It's that time of year again, and we've got a new version of macOS on our hands! This year we've finally jumped off the 10.xx naming scheme and now going to 11! And with that, a lot has changed under the hood in macOS. As with previous years, we'll be going over what's changed in macOS and what you should be aware of as a macOS and Hackintosh enthusiast.
Has Nvidia Support finally arrived?
What has changed on the surface
A whole new iOS-like UI
Broken Kexts in Big Sur
What has changed under the hood
New Kernel cache system: KernelCollections!
New Kernel Requirements
Secure Boot Changes
No more symbols required
Broken Kexts in Big Sur
MSI Navi installer Bug Resolved
New AMD OS X Kernel Patches
Other notable Hackintosh issues
Several SMBIOS have been dropped
Extra long install process
X79 and X99 Boot issues
New RTC requirements
Legacy GPU Patches currently unavailable
What’s new in the Hackintosh scene?
Dortania: a new organization has appeared
Dortania's Build Repo
True legacy macOS Support!
Intel Wireless: More native than ever!
Clover's revival? A frankenstein of a bootloader
Death of x86 and the future of Hackintoshing
Getting ready for macOS 11, Big Sur
Has Nvidia Support finally arrived?
Sadly every year I have to answer the obligatory question, no there is no new Nvidia support. Currently Nvidia's Kepler line is the only natively supported gen. However macOS 11 makes some interesting changes to the boot process, specifically moving GPU drivers into stage 2 of booting. Why this is relevant is due to Apple's initial reason for killing off Web Drivers: Secure boot. What I mean is that secure boot cannot work with Nvidia's Web Drivers due to how early Nvidia's drivers have to initialize at, and thus Apple refused to sign the binaries. With Big Sur, there could be 3rd party GPUs however the chances are still super slim but slightly higher than with 10.14 and 10.15.
What has changed on the surface
A whole new iOS-like UI
Love it or hate it, we've got a new UI more reminiscent of iOS 14 with hints of skeuomorphism(A somewhat subtle call back to previous mac UIs which have neat details in the icons) You can check out Apple's site to get a better idea:
A feature initially baked into APFS back in 2017 with the release of macOS 10.13, High Sierra, now macOS's main System volume has become both read-only and snapshotted. What this means is:
3rd parties have a much more difficult time modifying the system volume, allowing for greater security
OS updates can now be installed while you're using the OS, similar to how iOS handles updates
Time Machine can now more easily perform backups, without file inconsistencies with HFS Plus while you were using the machines
However there are a few things to note with this new enforcement of snapshotting:
OS snapshots are not calculated as used space, instead being labeled as purgeable space
Disabling macOS snapshots for the root volume with break software updates, and can corrupt data if one is applied
What has changed under the hood
Quite a few things actually! Both in good and bad ways unfortunately.
New Kernel Cache system: KernelCollections!
So for the past 15 years, macOS has been using the Prelinked Kernel as a form of Kernel and Kext caching. And with macOS Big Sur's new Read-only, snapshot based system volume, a new version of caching has be developed: KernelCollections! How this differs to previous OSes:
Kexts can no longer be hot-loaded, instead requiring a reboot to load with kmutil
OS Snapshots are now verified on each boot to ensure no system volume modifications occurred
apfs.kext and AppleImage4.kext verify the integrity of these snapshots
While technically these security features are optional and can be disabled after installation, many features including OS updates will no longer work reliably once disabled. This is due to the heavy reliance of snapshots for OS updates, as mentioned above and so we highly encourage all users to ensure at minimum SecureBootModel is set to Default or higher.
Note: ApECID is not required for functionality, and can be skipped if so desired.
Note 2: OpenCore 0.6.3 or newer is required for Secure Boot in Big Sur.
No more symbols required
This point is the most important part, as this is what we use for kext injection in OpenCore. Currently Apple has left symbols in place seemingly for debugging purposes however this is a bit worrying as Apple could outright remove symbols in later versions of macOS. But for Big Sur's cycle, we'll be good on that end however we'll be keeping an eye on future releases of macOS.
New Kernel Requirements
With this update, the AvoidRuntimeDefrag Booter quirk in OpenCore broke. Because of this, the macOS kernel will fall flat when trying to boot. Reason for this is due to cpu_count_enabled_logical_processors requiring the MADT (APIC) table, and so OpenCore will now ensure this table is made accessible to the kernel. Users will however need a build of OpenCore 0.6.0 with commit bb12f5for newer to resolve this issue. Additionally, both Kernel Allocation requirements and Secure Boot have also broken with Big Sur due to the new caching system discussed above. Thankfully these have also been resolved in OpenCore 0.6.3. To check your OpenCore version, run the following in terminal: nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:opencore-version If you're not up-to-date and running OpenCore 0.6.3+, see here on how to upgrade OpenCore: Updating OpenCore, Kexts and macOS
Broken Kexts in Big Sur
Unfortunately with the aforementioned KernelCollections, some kexts have unfortunately broken or have been hindered in some way. The main kexts that currently have issues are anything relying on Lilu's userspace patching functionality:
Big Sur dropped a few Ivy Bridge and Haswell based SMBIOS from macOS, so see below that yours wasn't dropped:
iMac14,3 and older
Note iMac14,4 is still supported
MacPro5,1 and older
MacMini6,x and older
MacBook7,1 and older
MacBookAir5,x and older
MacBookPro10,x and older
If your SMBIOS was supported in Catalina and isn't included above, you're good to go! We also have a more in-depth page here: Choosing the right SMBIOS For those wanting a simple translation for their Ivy and Haswell Machines:
iMac13,1 should transition over to using iMac14,4
iMac13,2 should transition over to using iMac15,1
iMac14,2 and iMac14,3 should transition over to using iMac15,1
Note: AMD CPUs users should transition over to MacPro7,1
iMac14,1 should transition over to iMac14,4
Currently only certain hardware has been officially dropped:
"Official" Consumer Ivy Bridge Support(U, H and S series)
These CPUs will still boot without much issue, but note that no Macs are supported with consumer Ivy Bridge in Big Sur.
Ivy Bridge-E CPUs are still supported thanks to being in MacPro6,1
Ivy Bridge iGPUs slated for removal
HD 4000 and HD 2500, however currently these drivers are still present in 11.0.1
Similar to Mojave and Nvidia's Tesla drivers, we expect Apple to forget about them and only remove them in the next major OS update next year
Due to the new snapshot-based OS, installation now takes some extra time with sealing. If you get stuck at Forcing CS_RUNTIME for entitlement, do not shutdown. This will corrupt your install and break the sealing process, so please be patient.
X79 and X99 Boot issues
With Big Sur, IOPCIFamily went through a decent rewriting causing many X79 and X99 boards to fail to boot as well as panic on IOPCIFamily. To resolve this issue, you'll need to disable the unused uncore bridge:
With macOS Big Sur, AppleRTC has become much more picky on making sure your OEM correctly mapped the RTC regions in your ACPI tables. This is mainly relevant on Intel's HEDT series boards, I documented how to patch said RTC regions in OpenCorePkg:
For those having boot issues on X99 and X299, this section is super important; you'll likely get stuck at PCI Configuration Begin. You can also find prebuilts here for those who do not wish to compile the file themselves:
For some reason, Apple removed the AppleIntelPchSeriesAHCI class from AppleAHCIPort.kext. Due to the outright removal of the class, trying to spoof to another ID (generally done by SATA-unsupported.kext) can fail for many and create instability for others. * A partial fix is to block Big Sur's AppleAHCIPort.kext and inject Catalina's version with any conflicting symbols being patched. You can find a sample kext here: Catalina's patched AppleAHCIPort.kext * This will work in both Catalina and Big Sur so you can remove SATA-unsupported if you want. However we recommend setting the MinKernel value to 20.0.0 to avoid any potential issues.
Legacy GPU Patches currently unavailable
Due to major changes in many frameworks around GPUs, those using ASentientBot's legacy GPU patches are currently out of luck. We either recommend users with these older GPUs stay on Catalina until further developments arise or buy an officially supported GPU
What’s new in the Hackintosh scene?
Dortania: a new organization has appeared
As many of you have probably noticed, a new organization focusing on documenting the hackintoshing process has appeared. Originally under my alias, Khronokernel, I started to transition my guides over to this new family as a way to concentrate the vast amount of information around Hackintoshes to both ease users and give a single trusted source for information. We work quite closely with the community and developers to ensure information's correct, up-to-date and of the best standards. While not perfect in every way, we hope to be the go-to resource for reliable Hackintosh information. And for the times our information is either outdated, missing context or generally needs improving, we have our bug tracker to allow the community to more easily bring attention to issues and speak directly with the authors:
Kexts here are built right after commit, and currently supports most of Acidanthera's kexts and some 3rd party devs as well. If you'd like to add support for more kexts, feel free to PR: Build Repo source
True legacy macOS Support!
As of OpenCore's latest versioning, 0.6.2, you can now boot every version of x86-based builds of OS X/macOS! A huge achievement on @Goldfish64's part, we now support every major version of kernel cache both 32 and 64-bit wise. This means machines like Yonah and newer should work great with OpenCore and you can even relive the old days of OS X like OS X 10.4! And Dortania guides have been updated accordingly to accommodate for builds of those eras, we hope you get as much enjoyment going back as we did working on this project!
Intel Wireless: More native than ever!
Another amazing step forward in the Hackintosh community, near-native Intel Wifi support! Thanks to the endless work on many contributors of the OpenIntelWireless project, we can now use Apple's built-in IO80211 framework to have near identical support to those of Broadcom wireless cards including features like network access in recovery and control center support. For more info on the developments, please see the itlwm project on GitHub: itlwm
Note, native support requires the AirportItlwm.kext and SecureBootModel enabled on OpenCore. Alternatively you can force IO80211Family.kext to ensure AirportItlwm works correctly.
Airdrop support currently is also not implemented, however is actively being worked on.
Clover's revival? A frankestien of a bootloader
As many in the community have seen, a new bootloader popped up back in April of 2019 called OpenCore. This bootloader was made by the same people behind projects such as Lilu, WhateverGreen, AppleALC and many other extremely important utilities for both the Mac and Hackintosh community. OpenCore's design had been properly thought out with security auditing and proper road mapping laid down, it was clear that this was to be the next stage of hackintoshing for the years we have left with x86. And now lets bring this back to the old crowd favorite, Clover. Clover has been having a rough time of recent both with the community and stability wise, with many devs jumping ship to OpenCore and Clover's stability breaking more and more with C++ rewrites, it was clear Clover was on its last legs. Interestingly enough, the community didn't want Clover to die, similarly to how Chameleon lived on through Enoch. And thus, we now have the Clover OpenCore integration project(Now merged into Master with r5123+). The goal is to combine OpenCore into Clover allowing the project to live a bit longer, as Clover's current state can no longer boot macOS Big Sur or older versions of OS X such as 10.6. As of writing, this project seems to be a bit confusing as there seems to be little reason to actually support Clover. Many of Clover's properties have feature-parity in OpenCore and trying to combine both C++ and C ruins many of the features and benefits either languages provide. The main feature OpenCore does not support is macOS-only ACPI injection, however the reasoning is covered here: Does OpenCore always inject SMBIOS and ACPI data into other OSes?
Death of x86 and the future of Hackintoshing
With macOS Big Sur, a big turning point is about to happen with Apple and their Macs. As we know it, Apple will be shifting to in-house designed Apple Silicon Macs(Really just ARM) and thus x86 machines will slowly be phased out of their lineup within 2 years. What does this mean for both x86 based Macs and Hackintoshing in general? Well we can expect about 5 years of proper OS support for the iMac20,x series which released earlier this year with an extra 2 years of security updates. After this, Apple will most likely stop shipping x86 builds of macOS and hackintoshing as we know it will have passed away. For those still in denial and hope something like ARM Hackintoshes will arrive, please consider the following:
We have yet to see a true iPhone "Hackintosh" and thus the likely hood of an ARM Hackintosh is unlikely as well
There have been successful attempts to get the iOS kernel running in virtual machines, however much work is still to be done
Apple's use of "Apple Silicon" hints that ARM is not actually what future Macs will be running, instead we'll see highly customized chips based off ARM
For example, Apple will be heavily relying on hardware features such as WX, kernel memory protection, Pointer Auth, etc for security and thus both macOS and Applications will be dependant on it. This means hackintoshing on bare-metal(without a VM) will become extremely difficult without copious amounts of work
Also keep in mind Apple Silicon will no longer be UEFI-based like Intel Macs currently are, meaning a huge amount of work would also be required on this end as well
So while we may be heart broken the journey is coming to a stop in the somewhat near future, hackintoshing will still be a time piece in Apple's history. So enjoy it now while we still can, and we here at Dortania will still continue supporting the community with our guides till the very end!
Getting ready for macOS 11, Big Sur
This will be your short run down if you skipped the above:
Lilu's userspace patcher is broken
Due to this many kexts will break:
WhateverGreen's DRM and -cdfon patches
Many Ivy Bridge and Haswell SMBIOS were dropped
See above for what SMBIOS to choose
Ivy Bridge iGPUs are to be dropped
Currently in 11.0.1, these drivers are still present
For the last 2, see here on how to update: Updating OpenCore, Kexts and macOS In regards to downloading Big Sur, currently gibMacOS in macOS or Apple's own software updater are the most reliable methods for grabbing the installer. Windows and Linux support is still unknown so please stand by as we continue to look into this situation, macrecovery.py may be more reliable if you require the recovery package. And as with every year, the first few weeks to months of a new OS release are painful in the community. We highly advise users to stay away from Big Sur for first time installers. The reason is that we cannot determine whether issues are Apple related or with your specific machine, so it's best to install and debug a machine on a known working OS before testing out the new and shiny. For more in-depth troubleshooting with Big Sur, see here: OpenCore and macOS 11: Big Sur
Samsung J3 Prime (2017) Android 7.0 Bootloader Unlock
I want to get Link2SD on my phone with Magisk but bc it's Samsung they removed the OEM Unlock feature from the dev options in an update so that's no use. If there's any other way to unlock my bootloader I'd love to hear it.
This is the CLI & GUI v0.17.1.3 'Oxygen Orion' point release. This release predominantly features bug fixes and performance improvements. Users, however, are recommended to upgrade, as it includes mitigations for the issue where transactions occasionally fail.
We encourage users to check the integrity of the binaries and verify that they were signed by binaryFate's GPG key. A guide that walks you through this process can be found here for Windows and here for Linux and Mac OS X.

Note that you should be able to utilize the automatic updater in the GUI that was recently added. A pop-up will appear shortly with the new binary. In case you want to update manually, you ought to perform the following steps:
Extract the new binaries (the .zip file (Windows) or the tar.bz2 file (Mac OS X and Linux) you just downloaded) to a new directory / folder of your liking.
Open monero-wallet-gui. It should automatically load your "old" wallet.
If, for some reason, the GUI doesn't automatically load your old wallet, you can open it as follows:  On the second page of the wizard (first page is language selection) choose Open a wallet from file  Now select your initial / original wallet. Note that, by default, the wallet files are located in Documents\Monero\ (Windows), Users//Monero/ (Mac OS X), or home//Monero/ (Linux). Lastly, note that a blockchain resync is not needed, i.e., it will simply pick up where it left off.
You ought to perform the following steps:
Download the new binaries (the .zip file (Windows) or the tar.bz2 file (Mac OS X and Linux)) from the official website, the direct download links in this thread, or Github.
Extract the new binaries to a new directory of your liking.
Copy over the wallet files from the old directory (i.e. the v0.15.x.x, v0.16.x.x, or v0.17.x.x directory).
Start monerod and monero-wallet-cli (in case you have to use your wallet).
Note that a blockchain resync is not needed. Thus, if you open monerod-v0.17.1.3, it will simply pick up where it left off.
In the wizard, you can either select Simple mode or Simple mode (bootstrap) to utilize this functionality. Note that the GUI developers / contributors recommend to use Simple mode (bootstrap) as this mode will eventually use your own (local) node, thereby contributing to the strength and decentralization of the network. Lastly, if you manually want to set a remote node, you ought to use Advanced mode. A guide can be found here: https://www.getmonero.org/resources/user-guides/remote_node_gui.html
How to Safely Flash Official One UI 2.5 (DBT) on SM-N960F
Hey Guys! https://youtu.be/hzHzSk5KPUE I will be showing you how to flash Official One UI 2.5 Germany DBT ROM on your device without deleting any data (if OEM is enabled otherwise you will have to backup). 3 Main Requirements before you start.
Make sure your chipset is Exynos (you can find out using CPU-Z app).
Model number must be either SM-N960F or SM-N960F/DS.
Binary Version should be either 6 or lower. (see the video below for better understanding)
1.1. On Phone > Goto Settings > Scroll Down > About Device > Software Information > Tap Build number 7 times > Go back to settings main page > scroll down > you will find new option called Developer options. Click on it > You will than find OEM unlocking (if OEM unlocking is not visible or is already enabled than you can skip to section *1.2*. If OEM unlocking is disabled, make sure you backup your device using SmartSwitch. 1.2. Download the necessary files from the video description. (Odin, Stock ROM (DBT), SmartSwitch, Samsung USB Drivers). 1.3. If you have SmartSwitch and USB Drivers already skip to *1.4*, disconnect cable to your device if connected than once you have installed both software/drivers make sure you reboot your PC. Launch SmartSwitch and simply press backup. 1.5. Once you are done now run Odin as administrator, click BL, AP, CP and CSC one by one and click on file that matches the starting letters located in your stock rom folder. NOTE: You will have 2 CSC files, Home_CSC is to keep data and not to format, CSC is to format the device. Pick the one you desire. 1.6. On your device, power it off, than plug in a usb cable to your PC, hold volume down + bixby button and power button simultaneously once it vibrates leave the power button but keep holding volume down + bixby button until you see warning screen, press volume up once to enter download mode. 1.7. Now you should see a blue highlighted ID:COM on Odin, you can simply press Start and it will do its job. 1.8. After it shows the PASS sign, you may close the odin and enjoy the One UI 2.5! :) If you get to know that your region released the One UI 2.5 you can follow the same step and flash your region rom and you will get the OTA updates with no issues. I also made a video since there isn't a video that explains step by step, I hope you enjoyed and thanks!
An introduction to Linux through Windows Subsystem for Linux
I'm working as an Undergraduate Learning Assistant and wrote this guide to help out students who were in the same boat I was in when I first took my university's intro to computer science course. It provides an overview of how to get started using Linux, guides you through setting up Windows Subsystem for Linux to run smoothly on Windows 10, and provides a very basic introduction to Linux. Students seemed to dig it, so I figured it'd help some people in here as well. I've never posted here before, so apologies if I'm unknowingly violating subreddit rules.
An introduction to Linux through Windows Subsystem for Linux
tl;dr skip to next section So you're thinking of installing a Linux distribution, and are unsure where to start. Or you're an unfortunate soul using Windows 10 in CPSC 201. Either way, this guide is for you. In this section I'll give a very basic intro to some of options you've got at your disposal, and explain why I chose Windows Subsystem for Linux among them. All of these have plenty of documentation online so Google if in doubt.
Dual-booting with Windows and a Linux distro
Will basically involve partitioning your drive and installing Linux from an external bootable USB through your computer's boot menu. You'll get the full Linux experience.
Lots of Linux flavors to choose from. For beginners, Ubuntu and Linux Mint are generally recommended. I have Ubuntu 18.04 LTS, I'd recommend Ubuntu 20.04 LTS since it's newer, but it's all up to you.
However, it can be a pain to constantly be switching between operating systems. Maybe you wanna make the full jump to Linux, maybe you don't.
Life pro tip: if you go down this route, disable Window 10's Fast Startup feature as it will get very screwy with a dual-boot. I've also included a helpful guide in Appendix B.
Using a virtual machine (VM) to run Linux
Involves downloading a VM, downloading a .iso image file of whatever operating system you'd like, and running on your local machine.
Devours RAM and is generally pretty slow, would not recommend.
Using terminal emulators
These provide commands and functionality similar to a Linux terminal, but are still running on Windows architecture.
These days, the most commonly-used Linux terminal is called bash. bash stands for Bourne Again Shell (no, Bourne is not a typo), and is likely what you'll be using as well.
Terminal emulators generally don't include a package manager, i.e. you can't download new bash programs, so pretty limited for general usage. BUT you can install a package manager externally, kind of hacky but can work.
Examples of terminal emulators include PuTTY, Git Bash, msys2 and mingw.
Using Windows Subsystem for Linux (either WSL 1 or WSL 2)
WSL provides a compatibility layer for running GNU/Linux programs natively on Windows 10. It has integration features certain Windows 10 development apps (notably Visual Studio Code) as well.
You've got two options, WSL 1 and WSL 2. WSL 2 was recently released and features a real Linux kernel, as opposed to an simulated kernel in WSL. This means WSL 2 offers significant performance advantages, but still lacks some of WSL 1's features.
WSL 1 is what I currently use, and thus what I'll be talking about in this guide. I'm not necessarily recommending it, frankly I regret not doing a dual-boot sooner and ditching Windows, but a dual-boot isn't for everyone and takes a lot of time you might not have right now.
Getting WSL initially setup is easy, but making it run smoothly requires some effort, and some features (like audio playback or displaying GUIs) require workarounds you can research if interested. WSL will also not work properly with low-level system tools.
With that out of the way, let's get started with setting up WSL 1 on your Windows 10 machine.
Setting up WSL
So if you've read this far I've convinced you to use WSL. Let's get started with setting it up. The very basics are outlined in Microsoft's guide here, I'll be covering what they talk about and diving into some other stuff.
1. Installing WSL
Press the Windows key (henceforth Winkey) and type in PowerShell. Right-click the icon and select run as administrator. Next, paste in this command:
Now you'll want to perform a hard shutdown on your computer. This can become unecessarily complicated because of Window's fast startup feature, but here we go. First try pressing the Winkey, clicking on the power icon, and selecting Shut Down while holding down the shift key. Let go of the shift key and the mouse, and let it shutdown. Great! Now open up Command Prompt and type in
If you get a large text output, WSL has been successfully enabled on your machine. If nothing happens, your computer failed at performing a hard shutdown, in which case you can try the age-old technique of just holding down your computer's power button until the computer turns itself off. Make sure you don't have any unsaved documents open when you do this.
2. Installing Ubuntu
Great! Now that you've got WSL installed, let's download a Linux distro. Press the Winkey and type in Microsoft Store. Now use the store's search icon and type in Ubuntu. Ubuntu is a Debian-based Linux distribution, and seems to have the best integration with WSL, so that's what we'll be going for. If you want to be quirky, here are some other options. Once you type in Ubuntu three options should pop up: Ubuntu, Ubuntu 20.04 LTS, and Ubuntu 18.04 LTS. ![Windows Store](https://theshepord.github.io/intro-to-WSL/docs/images/winstore.png) Installing plain-old "Ubuntu" will mean the app updates whenever a new major Ubuntu distribution is released. The current version (as of 09/02/2020) is Ubuntu 20.04.1 LTS. The other two are older distributions of Ubuntu. For most use-cases, i.e. unless you're running some software that will break when upgrading, you'll want to pick the regular Ubuntu option. That's what I did. Once that's done installing, again hit Winkey and open up Ubuntu. A console window should open up, asking you to wait a minute or two for files to de-compress and be stored on your PC. All future launches should take less than a second. It'll then prompt you to create a username and password. I'd recommend sticking to whatever your Windows username and password is so that you don't have to juggle around two different usepassword combinations, but up to you. Finally, to upgrade all your packages, type in
sudo apt-get update
sudo apt-get upgrade
apt-get is the Ubuntu package manager, this is what you'll be using to install additional programs on WSL.
3. Making things nice and crispy: an introduction to UNIX-based filesystems
tl;dr skip to the next section The two above steps are technically all you need for running WSL on your system. However, you may notice that whenever you open up the Ubuntu app your current folder seems to be completely random. If you type in pwd (for Print Working Directory, 'directory' is synonymous with 'folder') inside Ubuntu and hit enter, you'll likely get some output akin to /home/. Where is this folder? Is it my home folder? Type in ls (for LiSt) to see what files are in this folder. Probably you won't get any output, because surprise surprise this folder is not your Windows home folder and is in fact empty (okay it's actually not empty, which we'll see in a bit. If you type in ls -a, a for All, you'll see other files but notice they have a period in front of them. This is a convention for specifying files that should be hidden by default, and ls, as well as most other commands, will honor this convention. Anyways). So where is my Windows home folder? Is WSL completely separate from Windows? Nope! This is Windows Subsystem for Linux after all. Notice how, when you typed pwd earlier, the address you got was /home/. Notice that forward-slash right before home. That forward-slash indicates the root directory (not to be confused with the /root directory), which is the directory at the top of the directory hierarchy and contains all other directories in your system. So if we type ls /, you'll see what are the top-most directories in your system. Okay, great. They have a bunch of seemingly random names. Except, shocker, they aren't random. I've provided a quick run-down in Appendix A. For now, though, we'll focus on /mnt, which stands for mount. This is where your C drive, which contains all your Windows stuff, is mounted. So if you type ls /mnt/c, you'll begin to notice some familiar folders. Type in ls /mnt/c/Users, and voilà, there's your Windows home folder. Remember this filepath, /mnt/c/Users/. When we open up Ubuntu, we don't want it tossing us in this random /home/ directory, we want our Windows home folder. Let's change that!
4. Changing your default home folder
Type in sudo vim /etc/passwd. You'll likely be prompted for your Ubuntu's password. sudo is a command that gives you root privileges in bash (akin to Windows's right-click then selecting 'Run as administrator'). vim is a command-line text-editing tool, which out-of-the-box functions kind of like a crummy Notepad (you can customize it infinitely though, and some people have insane vim setups. Appendix B has more info). /etc/passwd is a plaintext file that historically was used to store passwords back when encryption wasn't a big deal, but now instead stores essential user info used every time you open up WSL. Anyway, once you've typed that in, your shell should look something like this: ![vim /etc/passwd](https://theshepord.github.io/intro-to-WSL/docs/images/vim-etc-passwd.png) Using arrow-keys, find the entry that begins with your Ubuntu username. It should be towards the bottom of the file. In my case, the line looks like
See that cringy, crummy /home/pizzatron3000? Not only do I regret that username to this day, it's also not where we want our home directory. Let's change that! Press i to initiate vim's -- INSERT -- mode. Use arrow-keys to navigate to that section, and delete /home/ by holding down backspace. Remember that filepath I asked you to remember? /mnt/c/Users/. Type that in. For me, the line now looks like
Next, press esc to exit insert mode, then type in the following:
The : tells vim you're inputting a command, w means write, and q means quit. If you've screwed up any of the above sections, you can also type in :q! to exit vim without saving the file. Just remember to exit insert mode by pressing esc before inputting commands, else you'll instead be writing to the file. Great! If you now open up a new terminal and type in pwd, you should be in your Window's home folder! However, things seem to be lacking their usual color...
5. Importing your configuration files into the new home directory
Your home folder contains all your Ubuntu and bash configuration files. However, since we just changed the home folder to your Window's home folder, we've lost these configuration files. Let's bring them back! These configuration files are hidden inside /home/, and they all start with a . in front of the filename. So let's copy them over into your new home directory! Type in the following:
cp -r /home//. ~
cp stands for CoPy, -r stands for recursive (i.e. descend into directories), the . at the end is cp-specific syntax that lets it copy anything, including hidden files, and the ~ is a quick way of writing your home directory's filepath (which would be /mnt/c/Users/) without having to type all that in again. Once you've run this, all your configuration files should now be present in your new home directory. Configuration files like .bashrc, .profile, and .bash_profile essentially provide commands that are run whenever you open a new shell. So now, if you open a new shell, everything should be working normally. Amazing. We're done!
6. Tips & tricks
Here are two handy commands you can add to your .profile file. Run vim ~/.profile, then, type these in at the top of the .profile file, one per line, using the commands we discussed previously (i to enter insert mode, esc to exit insert mode, :wq to save and quit). alias rm='rm -i' makes it so that the rm command will always ask for confirmation when you're deleting a file. rm, for ReMove, is like a Windows delete except literally permanent and you will lose that data for good, so it's nice to have this extra safeguard. You can type rm -f to bypass. Linux can be super powerful, but with great power comes great responsibility. NEVER NEVER NEVER type in rm -rf /, this is saying 'delete literally everything and don't ask for confirmation', your computer will die. Newer versions of rm fail when you type this in, but don't push your luck. You've been warned. Be careful. export DISPLAY=:0 if you install XLaunch VcXsrv, this line allows you to open graphical interfaces through Ubuntu. The export sets the environment variable DISPLAY, and the :0 tells Ubuntu that it should use the localhost display.
Appendix A: brief intro to top-level UNIX directories
tl;dr only mess with /mnt, /home, and maybe maybe /usr. Don't touch anything else.
bin: binaries, contains Ubuntu binary (aka executable) files that are used in bash. Here you'll find the binaries that execute commands like ls and pwd. Similar to /usbin, but bin gets loaded earlier in the booting process so it contains the most important commands.
boot: contains information for operating system booting. Empty in WSL, because WSL isn't an operating system.
dev: devices, provides files that allow Ubuntu to communicate with I/O devices. One useful file here is /dev/null, which is basically an information black hole that automatically deletes any data you pass it.
etc: no idea why it's called etc, but it contains system-wide configuration files
home: equivalent to Window's C:/Users folder, contains home folders for the different users. In an Ubuntu system, under /home/ you'd find the Documents folder, Downloads folder, etc.
lib: libraries used by the system
lib64 64-bit libraries used by the system
mnt: mount, where your drives are located
opt: third-party applications that (usually) don't have any dependencies outside the scope of their own package
proc: process information, contains runtime information about your system (e.g. memory, mounted devices, hardware configurations, etc)
run: directory for programs to store runtime information.
srv: server folder, holds data to be served in protocols like ftp, www, cvs, and others
sys: system, provides information about different I/O devices to the Linux Kernel. If dev files allows you to access I/O devices, sys files tells you information about these devices.
tmp: temporary, these are system runtime files that are (in most Linux distros) cleared out after every reboot. It's also sort of deprecated for security reasons, and programs will generally prefer to use run.
usr: contains additional UNIX commands, header files for compiling C programs, among other things. Kind of like bin but for less important programs. Most of everything you install using apt-get ends up here.
var: variable, contains variable data such as logs, databases, e-mail etc, but that persist across different boots.
Also keep in mind that all of this is just convention. No Linux distribution needs to follow this file structure, and in fact almost all will deviate from what I just described. Hell, you could make your own Linux fork where /mnt/c information is stored in tmp.
"From the Transistor to the Web Browser" George Hotz CS Curriculum
Found this on George Hotz's Github. Thinking of following this curriculum to get into CS. Would love to know everyone's thoughts. The only thing this curriculum lacks is links and resources. Credit: https://github.com/geohot/fromthetransistor "Hiring is hard, a lot of modern CS education is really bad, and it's hard to find people who understand the modern computer stack from first principles. Now cleaned up and going to be software only. Closer to being real.
Section 1: Intro: Cheating our way past the transistor -- 0.5 weeks
So about those transistors -- Course overview. Describe how FPGAs are buildable using transistors, and that ICs are just collections of transistors in a nice reliable package. Understand the LUTs and stuff. Talk briefly about the theory of transistors, but all projects must build on each other so we can’t build one.
Emulation -- Building on real hardware limits the reach of this course. Using something like Verilator will allow anyone with a computer to play.
Section 2: Bringup: What language is hardware coded in? -- 0.5 weeks
Blinking an LED(Verilog, 10) -- Your first little program! Getting the simulator working. Learning Verilog.
Building a UART(Verilog, 100) -- An intro chapter to Verilog, copy a real UART, introducing the concept of MMIO, though the serial port may be semihosting. Serial test echo program and led control.
Section 3: Processor: What is a processor anyway? -- 3 weeks
Coding an assembler(Python, 500) -- Straightforward and boring, write in python. Happens in parallel with the CPU building. Teaches you ARM assembly. Initially outputs just binary files, but changed when you write a linker.
Building a ARM7 CPU(Verilog, 1500) -- Break this into subchapters. A simple pipeline to start, decode, fetch, execute. How much BRAM do we have? We need at least 1MB, DDR would be hard I think, maybe an SRAM. Simulatable and synthesizable.
Coding a bootrom(Assembler, 40) -- This allows code download into RAM over the serial port, and is baked into the FPGA image. Cute test programs run on this.
Section 4: Compiler: A “high” level language -- 3 weeks
Building a C compiler(Haskell, 2000) -- A bit more interesting, cover the basics of compiler design. Write in haskell. Write a parser. Break this into subchapters. Outputs ARM assembly.
Building a linker(Python, 300) -- If you are clever, this should take a day. Output elf files. Use for testing with QEMU, semihosting.
libc + malloc(C, 500) -- The gateway to more complicated programs. libc is only half here, things like memcpy and memset and printf, but no syscall wrappers.
Building an ethernet controller(Verilog, 200) -- Talk to a real PHY, consider carefully MMIO design.
Writing a bootloader(C, 300) -- Write ethernet program to boot kernel over UDP. First thing written in C. Maybe don’t redownload over serial each time and embed in FPGA image.
Section 5: Operating System: Software we take for granted -- 3 weeks
Building an MMU(Verilog, 1000) -- ARM9ish, explain TLBs and other fun things. Maybe also a memory controller, depending on how the FPGA is, then add the init code to your bootloader.
Building an operating system(C, 2500) -- UNIXish, only user space threads. (open, read, write, close), (fork, execve, wait, sleep, exit), (mmap, munmap, mprotect). Consider the debug interface you are using, ranging from printf to perhaps a gdbremote stub into kernel. Break into subchapters.
Talking to an SD card(Verilog, 150) -- The last hardware you have to do. And a driver
FAT(C, 300) -- A real filesystem, I think fat is the simplest
init, shell, download, cat, ls, rm(C, 250) -- Your first user space programs.
Section 6: Browser: Coming online -- 1 week
Building a TCP stack(C, 500) -- Probably coded in the kernel, integrate the ethernet driver into the kernel. Add support for networking syscalls to kernel. (send, recv, bind, connect)
telnetd, the power of being multiprocess(C, 50) -- Written in C, user can connect multiple times with telnet. Really just a bind shell.
Space saving dynamic linking(C, 300) -- Because we can, explain how dynamic linker is just a user space program. Changes to linker required.
So about that web(C, 500+) -- A “nice” text based web browser, using ANSI and terminal niceness. Dynamically linked and nice, nice as you want.
Section 7: Physical: Running on real hardware -- 1 week
Talking to an FPGA(C, 200) -- A little code for the USB MCU to bitbang JTAG.
Building an FPGA board -- Board design, FPGA BGA reflow, FPGA flash, a 50mhz clock, a USB JTAG port and flasher(no special hardware, a little cypress usb mcu to do jtag), a few leds, a reset button, a serial port(USB-FTDI) also powering via USB, an sd card, expansion connector(ide cable?), and an ethernet port. Optional, expansion board, host USB port, NTSC TV out, an ISA port, and PS/2 connector on the board to taunt you. We provide a toaster oven and a multimeter thermometer to do reflow.

It will tell you what needs to be done, when it needs to be done, what you will be doing and why you will be doing it, all in one convenient manual that is made for Windows users. Although if you'd want to try it on Linux or MacOS we did add the commands necesary to get the CodeReady Containers to run on your operating system. Be warned however there are some system requirements that are necessary to run the CodeReady Containers that we will be using. These requirements are specified within chapter Minimum system requirements. This manual is written for everyone with an interest in the Red Hat OpenShift Container Platform and has at least a basic understanding of the command line within PowerShell on Windows. Even though it is possible to use most of the manual for Linux or MacOS we will focus on how to do this within Windows. If you follow this manual you will be able to do the following items by yourself: ● Installing the CodeReady Containers ● Updating OpenShift ● Configuring a CodeReady Container ● Configuring the DNS ● Accessing the OpenShift cluster ● Deploying the Mediawiki application What is the OpenShift Container platform? Red Hat OpenShift is a cloud development Platform as a Service (PaaS). It enables developers to develop and deploy their applications on a cloud infrastructure. It is based on the Kubernetes platform and is widely used by developers and IT operations worldwide. The OpenShift Container platform makes use of CodeReady Containers. CodeReady Containers are pre-configured containers that can be used for developing and testing purposes. There are also CodeReady Workspaces, these workspaces are used to provide any member of the development or IT team with a consistent, secure, and zero-configuration development environment. The OpenShift Container Platform is widely used because it helps the programmers and developers make their application faster because of CodeReady Containers and CodeReady Workspaces and it also allows them to test their application in the same environment. One of the advantages provided by OpenShift is the efficient container orchestration. This allows for faster container provisioning, deploying and management. It does this by streamlining and automating the automation process. What knowledge is required or recommended to proceed with the installation? To be able to follow this manual some knowledge is mandatory, because most of the commands are done within the Command Line interface it is necessary to know how it works and how you can browse through files/folders. If you either don’t have this basic knowledge or have trouble with the basic Command Line Interface commands from PowerShell, then a cheat sheet might offer some help. We recommend the following cheat sheet for windows: ● Https://www.sans.org/security-resources/sec560/windows\_command\_line\_sheet\_v1.pdf Another option is to read through the operating system’s documentation or introduction guides. Though the documentation can be overwhelming by the sheer amount of commands. ● Microsoft:https://docs.microsoft.com/en-us/windows-serveadministration/windows-commands/windows-commands ● MacOS Https://www.makeuseof.com/tag/mac-terminal-commands-cheat-sheet/ ● Linux https://ubuntu.com/tutorials/command-line-for-beginners#2-a-brief-history-lessonhttps://www.guru99.com/linux-commands-cheat-sheet.html http://cc.iiti.ac.in/docs/linuxcommands.pdf Aside from the required knowledge there are also some things that can be helpful to know just to make the use of OpenShift a bit simpler. This consists of some general knowledge on PaaS like Dockers and Kubernetes.
The minimum system requirements for the Red Hat OpenShift CodeReady Containers has the following minimum hardware: Hardware requirements Code Ready Containers requires the following system resources: ● 4 virtual CPU’s ● 9 GB of free random-access memory ● 35 GB of storage space ● Physical CPU with Hyper-V (intel) or SVM mode (AMD) this has to be enabled in the bios Software requirements The minimum system requirements for the Red Hat OpenShift CodeReady Containers has the following minimum operating system requirements: Microsoft Windows On Microsoft Windows, the Red Hat OpenShift CodeReady Containers requires the Windows 10 Pro Fall Creators Update (version 1709) or newer. CodeReady Containers does not work on earlier versions or other editions of Microsoft Windows. Microsoft Windows 10 Home Edition is not supported. macOS On macOS, the Red Hat OpenShift CodeReady Containers requires macOS 10.12 Sierra or newer. Linux On Linux, the Red Hat OpenShift CodeReady Containers is only supported on Red Hat Enterprise Linux/CentOS 7.5 or newer and on the latest two stable Fedora releases. When using Red Hat Enterprise Linux, the machine running CodeReady Containers must be registered with the Red Hat Customer Portal. Ubuntu 18.04 LTS or newer and Debian 10 or newer are not officially supported and may require manual set up of the host machine.
Required additional software packages for Linux
The CodeReady Containers on Linux require the libvirt and Network Manager packages to run. Consult the following table to find the command used to install these packages for your Linux distribution: Table 1.1 Package installation commands by distribution
To install CodeReady Containers a few steps must be undertaken. Because an OpenShift account is necessary to use the application this will be the first step. An account can be made on “https://www.openshift.com/”, where you need to press login and after that select the option “Create one now” After making an account the next step is to download the latest release of CodeReady Containers and the pulled secret on “https://cloud.redhat.com/openshift/install/crc/installer-provisioned”. Make sure to download the version corresponding to your platform and/or operating system. After downloading the right version, the contents have to be extracted from the archive to a location in your $PATH. The pulled secret should be saved because it is needed later. The command line interface has to be opened before we can continue with the installation. For windows we will use PowerShell. All the commands we use during the installation procedure of this guide are going to be done in this command line interface unless stated otherwise. To be able to run the commands within the command line interface, use the command line interface to go to the location in your $PATH where you extracted the CodeReady zip. If you have installed an outdated version and you wish to update, then you can delete the existing CodeReady Containers virtual machine with the $crc deletecommand. After deleting the container, you must replace the old crc binary with a newly downloaded binary of the latest release.
When you have done the previous steps please confirm that the correct and up to date crc binary is in use by checking it with the $crc version command, this should provide you with the version that is currently installed.
To set up the host operating system for the CodeReady Containers virtual machine you have to run the $crc setup command. After running crc setup, crc start will create a minimal OpenShift 4 cluster in the folder where the executable is located.
Setting up CodeReady Containers
Now we need to set up the new CodeReady Containers release with the $crc setup command. This command will perform the operations necessary to run the CodeReady Containers and create the ~/.crc directory if it did not previously exist. In the process you have to supply your pulled secret, once this process is completed you have to reboot your system. When the system has restarted you can start the new CodeReady Containers virtual machine with the $crc start command. The $crc start command starts the CodeReady virtual machine and OpenShift cluster. You cannot change the configuration of an existing CodeReady Containers virtual machine. So if you have a CodeReady Containers virtual machine and you want to make configuration changes you need to delete the virtual machine with the $crc deletecommand and create a new virtual machine and start that one with the configuration changes. Take note that deleting the virtual machine will also delete the data stored in the CodeReady Containers. So, to prevent data loss we recommend you save the data you wish to keep. Also keep in mind that it is not necessary to change the default configuration to start OpenShift.
Before starting the machine, you need to keep in mind that it is not possible to make any changes to the virtual machine. For this tutorial however it is not necessary to change the configuration, if you don’t want to make any changes please continue by starting the machine with the crc start command.
\ it is possible that you will get a Nameserver error later on, if this is the case please start it with* crc start -n 220.127.116.11
It is not is not necessary to change the default configuration and continue with this tutorial, this chapter is here for those that wish to do so and know what they are doing. However, for MacOS and Linux it is necessary to change the dns settings.
Configuring the CodeReady Containers
To start the configuration of the CodeReady Containers use the command crc config. This command allows you to configure the crc binary and the CodeReady virtual machine. The command has some requirements before it’s able to configure. This requirement is a subcommand, the available subcommands for this binary and virtual machine are: ● get, this command allows you to see the values of a configurable property ● set/unset, this command can be used for 2 things. To display the names of, or to set and/or unset values of several options and parameters. These parameters being: ○ Shell options ○ Shell attributes ○ Positional parameters ● view, this command starts the configuration in read-only mode. These commands need to operate on named configurable properties. To list all the available properties, you can run the command $crc config --help. Throughout this manual we will use the $crc config command a few times to change some properties needed for the configuration. There is also the possibility to use the crc config command to configure the behavior of the checks that’s done by the $crc start end $crc setup commands. By default, the startup checks will stop with the process if their conditions are not met. To bypass this potential issue, you can set the value of a property that starts with skip-check or warn-check to true to skip the check or warning instead of ending up with an error.
C:\Users\[username]\$PATH>crc config get C:\Users\[username]\$PATH>crc config set C:\Users\[username]\$PATH>crc config unset C:\Users\[username]\$PATH>crc config view C:\Users\[username]\$PATH>crc config --help
Configuring the Virtual Machine
You can use the CPUs and memory properties to configure the default number of vCPU’s and amount of memory available for the virtual machine. To increase the number of vCPU’s available to the virtual machine use the $crc config set CPUs . Keep in mind that the default number for the CPU’s is 4 and the number of vCPU’s you wish to assign must be equal or greater than the default value. To increase the memory available to the virtual machine, use the $crc config set memory . Keep in mind that the default number for the memory is 9216 Mebibytes and the amount of memory you wish to assign must be equal or greater than the default value.
C:\Users\[username]\$PATH>crc config set CPUs C:\Users\[username]\$PATH>crc config set memory >
Configuring the DNS
Window / General DNS setup
There are two domain names used by the OpenShift cluster that are managed by the CodeReady Containers, these are: ● crc.testing, this is the domain for the core OpenShift services. ● apps-crc.testing, this is the domain used for accessing OpenShift applications that are deployed on the cluster. Configuring the DNS settings in Windows is done by executing the crc setup. This command automatically adjusts the DNS configuration on the system. When executing crc start additional checks to verify the configuration will be executed.
macOS DNS setup
MacOS expects the following DNS configuration for the CodeReady Containers ● The CodeReady Containers creates a file that instructs the macOS to forward all DNS requests for the testing domain to the CodeReady Containers virtual machine. This file is created at /etc/resolvetesting. ● The oc binary requires the following CodeReady Containers entry to function properly, api.crc.testing adds an entry to /etc/hosts pointing at the VM IPaddress.
Linux DNS setup
CodeReady containers expect a slightly different DNS configuration. CodeReady Container expects the NetworkManager to manage networking. On Linux the NetworkManager uses dnsmasq through a configuration file, namely /etc/NetworkManageconf.d/crc-nm-dnsmasq.conf. To set it up properly the dnsmasq instance has to forward the requests for crc.testing and apps-crc.testing domains to “192.168.130.11”. In the /etc/NetworkManageconf.d/crc-nm-dnsmasq.conf this will look like the following: ● Server=/crc. Testing/192.168.130.11 ● Server=/apps-crc. Testing/192.168.130.11
Accessing the Openshift Cluster
Accessing the Openshift web console
To gain access to the OpenShift cluster running in the CodeReady virtual machine you need to make sure that the virtual machine is running before continuing with this chapter. The OpenShift clusters can be accessed through the OpenShift web console or the client binary(oc). First you need to execute the $crc console command, this command will open your web browser and direct a tab to the web console. After that, you need to select the htpasswd_provider option in the OpenShift web console and log in as a developer user with the output provided by the crc start command. It is also possible to view the password for kubeadmin and developer users by running the $crc console --credentials command. While you can access the cluster through the kubeadmin and developer users, it should be noted that the kubeadmin user should only be used for administrative tasks such as user management and the developer user for creating projects or OpenShift applications and the deployment of these applications.
To gain access to the OpenShift cluster with the use of the oc command you need to complete several steps. Step 1. Execute the $crc oc-env command to print the command needed to add the cached oc binary to your PATH:
Step 2. Execute the printed command. The output will look something like the following:
PS C:\Users\OpenShift> crc oc-env $Env:PATH = "CC:\Users\OpenShift\.crc\bin\oc;$Env:PATH" # Run this command to configure your shell: # & crc oc-env | Invoke-Expression
This means we have to execute* the command that the output gives us, in this case that is:
\this has to be executed every time you start; a solution is to move the oc binary to the same path as the crc binary* To test if this step went correctly execute the following command, if it returns without errors oc is set up properly
Step 3 Now you need to login as a developer user, this can be done using the following command: $oc login -u developerhttps://api.crc.testing:6443 Keep in mind that the $crc start will provide you with the password that is needed to login with the developer user.
Step 4 The oc can now be used to interact with your OpenShift cluster. If you for instance want to verify if the OpenShift cluster Operators are available, you can execute the command
$oc get co
Keep in mind that by default the CodeReady Containers disables the functions provided by the commands $machine-config and $monitoringOperators.
C:\Users\[username]\$PATH>oc get co
Now that you are able to access the cluster, we will take you on a tour through some of the possibilities within OpenShift Container Platform. We will start by creating a project. Within this project we will import an image, and with this image we are going to build an application. After building the application we will explain how upscaling and downscaling can be used within the created application. As the next step we will show the user how to make changes in the network route. We also show how monitoring can be used within the platform, however within the current version of CodeReady Containers this has been disabled. Lastly, we will show the user how to use user management within the platform.
In OpenShift there is a feature called autoscaling. There are two types of application scaling, namely vertical scaling, and horizontal scaling. Vertical scaling is adding only more CPU and hard disk and is no longer supported by OpenShift. Horizontal scaling is increasing the number of machines. One of the ways to scale an application is by increasing the number of pods. This can be done by going to a pod within the view as seen in the previous step. By either pressing the up or down arrow more pods of the same application can be added. This is similar to horizontal scaling and can result in better performance when there are a lot of active users at the same time. https://preview.redd.it/s6i1vbcrltv51.png?width=602&format=png&auto=webp&s=e62cbeeed116ba8c55704d61a990fc0d8f3cfaa1 In the picture above we see the number of nodes and pods and how many resources those nodes and pods are using. This is something to keep in mind if you want to scale up your application, the more you scale it up, the more resources it will take up. https://preview.redd.it/quh037wmitv51.png?width=194&format=png&auto=webp&s=5e326647b223f3918c259b1602afa1b5fbbeea94
It is however important to know how to manually reclaim the persistent volumes, since if you delete PV the associated data will not be automatically deleted with it and therefore you cannot reassign the storage to another PV yet. To manually reclaim the PV, you need to follow the following steps: Step 1: Delete the PV, this can be done by executing the following command
Step 2: Now you need to clean up the data on the associated storage asset Step 3: Now you can delete the associated storage asset or if you with to reuse the same storage asset you can now create a PV with the storage asset definition. It is also possible to directly change the reclaim policy within OpenShift, to do this you would need to follow the following steps: Step 1: Get a list of the PVs in your cluster
$oc get pv
This will give you a list of all the PV’s in your cluster and will display their following attributes: Name, Capacity, Accesmodes, Reclaimpolicy, Statusclaim, Storageclass, Reason and Age. Step 2: Now choose the PV you wish to change and execute one of the following command’s, depending on your preferred policy:
According to the documentation of OpenShift is a user, an entity that interacts with the OpenShift Container Platform API. These can be a developer for developing applications or an administrator for managing the cluster. Users can be assigned to groups, which set the permissions applied to all the group’s members. For example, you can give API access to a group, which gives all members of the group API access. There are multiple ways to create a user depending on the configured identity provider. The DenyAll identity provider is the default within OpenShift Container Platform. This default denies access for all the usernames and passwords. First, we’re going to create a new user, the way this is done depends on the identity provider, this depends on the mapping method used as part of the identity provider configuration. for more information on what mapping methods are and how they function: https://docs.openshift.com/enterprise/3.1/install_config/configuring_authentication.html With the default mapping method, the steps will be as following
$oc create user
Next up, we’ll create an OpenShift Container Platform Identity. Use the name of the identity provider and the name that uniquely represents this identity in the scope of the identity provider:
$oc create identity :
The is the name of the identity provider in the master configuration. For example, the following commands create an Identity with identity provider ldap_provider and the identity provider username mediawiki_s.
$oc create identity ldap_provider:mediawiki_s
Create a useidentity mapping for the created user and identity:
$oc create useridentitymapping :
For example, the following command maps the identity to the user:
There is a --clusterrole option that can be used to give the user a specific role, like a cluster user with admin privileges. The cluster admin has access to all files and is able to manage the access level of other users. Below is an example of the admin clusterrole command:
If you followed all the steps within this manual you now should have a functioning Mediawiki Application running on your own CodeReady Containers. During the installation of this application on CodeReady Containers you have learned how to do the following things: ● Installing the CodeReady Containers ● Updating OpenShift ● Configuring a CodeReady Container ● Configuring the DNS ● Accessing the OpenShift cluster ● Deploying an application ● Creating new users With these skills you’ll be able to set up your own Container Platform environment and host applications of your choosing.
Nameserver There is the possibility that your CodeReady container can't connect to the internet due to a Nameserver error. When this is encountered a working fix for us was to stop the machine and then start the CRC machine with the following command:
C:\Users\[username]\$PATH>crc start -n 18.104.22.168
Hyper-V admin Should you run into a problem with Hyper-V it might be because your user is not an admin and therefore can’t access the Hyper-V admin user group.
Click Start > Control Panel > Administration Tools > Computer Management. The Computer Management window opens.
Click System Tools > Local Users and Groups > Groups. The list of groups opens.
Double-click the Hyper-V Administrators group. The Hyper-V Administrators Properties window opens.
Click Add. The Select Users or Groups window opens.
In the Enter the object names to select field, enter the user account name to whom you want to assign permissions, and then click OK.
Click Apply, and then click OK.
Terms and definitions
These terms and definitions will be expanded upon, below you can see an example of how this is going to look like together with a few terms that will require definitions. ● Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. Openshift is based on Kubernetes. ● Clusters are a collection of multiple nodes which communicate with each other to perform a set of operations. ● Containers are the basic units of OpenShift applications. These container technologies are lightweight mechanisms for isolating running processes so that they are limited to interacting with only their designated resources. ● CodeReady Container is a minimal, preconfigured cluster that is used for development and testing purposes. ● CodeReady Workspaces uses Kubernetes and containers to provide any member of the development or IT team with a consistent, secure, and zero-configuration development environment.
Ethereum on ARM. New Eth2.0 Raspberry Pi 4 image for joining the Medalla multi-client testnet. Step-by-step guide for installing and activating a validator (Prysm, Teku, Lighthouse and Nimbus clients included)
TL;DR: Flash your Raspberry Pi 4, plug in an ethernet cable, connect the SSD disk and power up the device to join the Eth2.0 medalla testnet. The image takes care of all the necessary steps to join the Eth2.0 Medalla multi-client testnet , from setting up the environment and formatting the SSD disk to installing, managing and running the Eth1.0 and Eth2.0 clients. You will only need to choose an Eth2.0 client, start the beacon chain service and activate / run the validator. Note: this is an update for our previous Raspberry Pi 4 Eth2 image  so some of the instructions are directly taken from there.
Based on Ubuntu 20.04 64bit.
Automatic USB disk partitioning and formatting
Adds swap memory (ZRAM kernel module + a swap file)
Changes the hostname to something like “ethnode-e2a3e6fe” based on MAC hash
Automatically syncs Eth1 Goerli testnet (Geth)
Includes an APT repository for installing and upgrading Ethereum software
Includes 4 Eth2.0 clients
Includes EF eth2.0-deposit-cli tool
Includes 5 monitoring dashboards based on Grafana / Prometheus
Geth: 1.9.20  (official binary) configured for syncing Goerli Testnets
Eth2.0-deposit-cli: 0.2.1 (bundled) 
Prysm: 1.0.0alpha24 
Beacon Chain (official binary)

Teku: 0.12.4alpha+20200821 (compiled) 
Lighthouse 0.2.8 (official binary) 
Nimbus 0.5.0 (compiled) 
Grafana 7.0.4 (official package) 
INSTALLATION GUIDE AND USAGE
RECOMMENDED HARDWARE AND SETUP
Raspberry 4 (model B) - 4GB or 8GB (8 GB RAM highly recommended)
MicroSD Card (16 GB Class 10 minimum)
SSD USB 3.0 disk (see storage section)
A case with heatsink and fan (Optional but strongly recommended)
USB keyboard, Monitor and HDMI cable (micro-HDMI) (Optional)
STORAGE You will need an SSD to run the Ethereum clients (without an SSD drive there’s absolutely no chance of syncing the Ethereum blockchain). There are 2 options: Use an USB portable SSD disk such as the Samsung T5 Portable SSD. Use an USB 3.0 External Hard Drive Case with a SSD Disk. In our case we used a Inateck 2.5 Hard Drive Enclosure FE2011. Make sure to buy a case with an UASP compliant chip, particularly, one of these: JMicron (JMS567 or JMS578) or ASMedia (ASM1153E). In both cases, avoid getting low quality SSD disks as it is a key component of your node and it can drastically affect the performance (and sync times). Keep in mind that you need to plug the disk to an USB 3.0 port (in blue). IMAGE DOWNLOAD AND INSTALLATION 1.- Download the image: http://www.ethraspbian.com/downloads/ubuntu-20.04.1-preinstalled-server-arm64+raspi-eth2-medalla.img.zip SHA256 149cb9b020d1c49fcf75c00449c74c6f38364df1700534b5e87f970080597d87 2.- Flash the image Insert the microSD in your Desktop / Laptop and download the file. Note: If you are not comfortable with command line or if you are running Windows, you can use Etcher  Open a terminal and check your MicroSD device name running: sudo fdisk -l You should see a device named mmcblk0 or sdd. Unzip and flash the image: unzip ubuntu-20.04.1-preinstalled-server-arm64+raspi-eth2-medalla.img.zip sudo dd bs=1M if=ubuntu-20.04.1-preinstalled-server-arm64+raspi.img of=/dev/mmcblk0 conv=fdatasync status=progress 3.- Insert de MicroSD into the Raspberry Pi 4. Connect an Ethernet cable and attach the USB SSD disk (make sure you are using a blue port). 4.- Power on the device The Ubuntu OS will boot up in less than one minute but you will need to wait approximately 7-8 minutes in order to allow the script to perform the necessary tasks to install the Medalla setup (it will reboot again) 5.- Log in You can log in through SSH or using the console (if you have a monitor and keyboard attached)
User: ethereum Password: ethereum
You will be prompted to change the password on first login, so you will need to log in twice. 6.- Forward 30303 port in your router (both UDP and TCP). If you don’t know how to do this, google “port forwarding” followed by your router model. You will need to open additional ports as well depending on the Eth2.0 client you’ve chosen. 7.- Getting console output You can see what’s happening in the background by typing: sudo tail -f /valog/syslog 8.- Grafana Dashboards There are 5 Grafana dashboards available to monitor the Medalla node (see section “Grafana Dashboards” below).
The Medalla Eth2.0 multi-client testnet
Medalla is the official Eth2.0 multi-client testnet according to the latest official specification for Eth2.0, the v0.12.2  release (which is aimed to be the final) . In order to run a Medalla Eth 2.0 node you will need 3 components:
An Eth1.0 node running the Goerli testnet in sync . Geth in our case.
An Eth2.0 Beacon Chain connected to the Eth1.0 node. You will need to choose a client here (Prysm, Lighthouse, Teku or Nimbus)
An Eth2.0 Validator connected to the Beacon Chain (same client as the Beacon Chain)
The image takes care of the Eth1.0 setup. So, once flashed (and after a first reboot), Geth (Eth1.0 client) starts to sync the Goerli testnet. Follow these steps to enable your Eth2.0 Ethereum node: CREATE THE VALIDATOR KEYS AND MAKE THE DEPOSIT We need to get 32 Goerli ETH (fake ETH) ir order to make the deposit in the Eth2.0 contract and run the validator. The easiest way of getting ETH is by joining Prysm Discord's channel. Open Metamask , select the Goerli Network (top of the window) and copy your ETH Address. Go to: https://discord.com/invite/YMVYzv6 And open the “request-goerli-eth” channel (on the left) Type: !send $YOUR_ETH_ADDRESS (replace it with the one copied on Metamask) You will receive enough ETH to run 1 validator. Now it is time to create your validator keys and the deposit information. For your convenience we’ve packaged the official Eth2 launchpad tool . Go to the EF Eth2.0 launchpad site: https://medalla.launchpad.ethereum.org/ And click “Get started” Read and accept all warnings. In the next screen, select 1 validator and go to your Raspberry Pi console. Under the ethereum account run: cd && deposit --num_validators 1 --chain medalla Choose your mnemonic language and type a password for keeping your keys safe. Write down your mnemonic password, press any key and type it again as requested. Now you have 2 Json files under the validator_keys directory. A deposit data file for sending the 32 ETH along with your validator public key to the Eth1 chain (goerli testnet) and a keystore file with your validator keys. Back to the Launchpad website, check "I am keeping my keys safe and have written down my mnemonic phrase" and click "Continue". It is time to send the 32 ETH deposit to the Eth1 chain. You need the deposit file (located in your Raspberry Pi). You can, either copy and paste the file content and save it as a new file in your desktop or copy the file from the Raspberry to your desktop through SSH. 1.- Copy and paste: Connected through SSH to your Raspberry Pi, type: cat validator_keys/deposit_data-$FILE-ID.json (replace $FILE-ID with yours) Copy the content (the text in square brackets), go back to your desktop, paste it into your favourite editor and save it as a json file. Or 2.- Ssh: From your desktop, copy the file: scp [email protected]$YOUR_RASPBERRYPI_IP:/home/ethereum/validator_keys/deposit_data-$FILE_ID.json /tmp Replace the variables with your data. This will copy the file to your desktop /tmp directory. Upload the deposit file Now, back to the Launchpad website, upload the deposit_data file and select Metamask, click continue and check all warnings. Continue and click “Initiate the Transaction”. Confirm the transaction in Metamask and wait for the confirmation (a notification will pop up shortly). The Beacon Chain (which is connected to the Eth1 chain) will detect this deposit (that includes the validator public key) and the Validator will be enabled. Congrats!, you just started your validator activation process. CHOOSE AN ETH2.0 CLIENT Time to choose your Eth2.0 client. We encourage you to run Lighthouse, Teku or Nimbus as Prysm is the most used client by far and diversity is key to achieve a resilient and healthy Eth2.0 network. Once you have decided which client to run (as said, try to run one with low network usage), you need to set up the clients and start both, the beacon chain and the validator. These are the instructions for enabling each client (Remember, choose just one Eth2.0 client out of 4): LIGHTHOUSE ETH2.0 CLIENT 1.- Port forwarding You need to open the 9000 port in your router (both UDP and TCP) 2.- Start the beacon chain Under the ethereum account, run: sudo systemctl enable lighthouse-beacon sudo systemctl start lighthouse-beacon 3.- Start de validator We need to import the validator keys. Run under the ethereum account: lighthouse account validator import --directory=/home/ethereum/validator_keys Then, type your previously defined password and run: sudo systemctl enable lighthouse-validator sudo systemctl start lighthouse-validator The Lighthouse beacon chain and validator are now enabled PRYSM ETH2.0 CLIENT 1.- Port forwarding You need to open the 13000 and 12000 ports in your router (both UDP and TCP) 2.- Start the beacon chain Under the ethereum account, run: sudo systemctl enable prysm-beacon sudo systemctl start prysm-beacon 3.- Start de validator We need to import the validator keys. Run under the ethereum account: validator accounts-v2 import --keys-dir=/home/ethereum/validator_keys Accept the default wallet path and enter a password for your wallet. Now enter the password previously defined. Lastly, set up your password and start the client: echo "$YOUR_PASSWORD" > /home/ethereum/validator_keys/prysm-password.txt sudo systemctl enable prysm-validator sudo systemctl start prysm-validator The Prysm beacon chain and the validator are now enabled. TEKU ETH2.0 CLIENT 1.- Port forwarding You need to open the 9151 port (both UDP and TCP) 2.- Start the Beacon Chain and the Validator Under the Ethereum account, check the name of your keystore file: ls /home/ethereum/validator_keys/keystore* Set the keystore file name in the teku config file (replace the $KEYSTORE_FILE variable with the file listed above) sudo sed -i 's/changeme/$KEYSTORE_FILE/' /etc/ethereum/teku.conf Set the password previously entered: echo "yourpassword" > validator_keys/teku-password.txt Start the beacon chain and the validator: sudo systemctl enable teku sudo systemctl start teku The Teku beacon chain and validator are now enabled. NIMBUS ETH2.0 CLIENT 1.- Port forwarding You need to open the 19000 port (both UDP and TCP) 2.- Start the Beacon Chain and the Validator We need to import the validator keys. Run under the ethereum account: beacon_node deposits import /home/ethereum/validator_keys --data-dir=/home/ethereum/.nimbus --log-file=/home/ethereum/.nimbus/nimbus.log Enter the password previously defined and run: sudo systemctl enable nimbus sudo systemctl start nimbus The Nimbus beacon chain and validator are now enabled. WHAT's NEXT Now you need to wait for the Eth1 blockchain and the beacon chain to get synced. In a few hours the validator will get enabled and put into a queue. These are the validator status that you will see until its final activation:
DEPOSITED (the beacon chain detected the 32 ETH deposit with your validator public key)
PENDING (you are in a queue for being activated)
Finally, it will get activated and the staking process will start. Congratulations!, you join the Medalla Eth2.0 multiclient testnet!
We configured 5 Grafana Dashboards to let users monitor both Eth1.0 and Eth2.0 clients. To access the dashboards just open your browser and type your Raspberry IP followed by the 3000 port:
Lots of info here. You can see for example if Geth is in sync by checking (in the Blockchain section) if Headers, Receipts and Blocks fields are aligned or find Eth2.0 chain info.
Updating the software
We will be keeping the Eth2.0 clients updated through Debian packages in order to keep up with the testnet progress. Basically, you need to update the repo and install the packages through the apt command. For instance, in order to update all packages you would run: sudo apt-get update && sudo apt-get install geth teku nimbus prysm-beacon prysm-validator lighthouse-beacon lighthouse-validator Please follow us on Twitter in order to get regular updates and install instructions. https://twitter.com/EthereumOnARM
MAME 0.223 has finally arrived, and what a release it is – there’s definitely something for everyone! Starting with some of the more esoteric additions, Linus Åkesson’s AVR-based hardware chiptune project and Power Ninja Action Challenge demos are now supported. These demos use minimal hardware to generate sound and/or video, relying on precise CPU timings to work. With this release, every hand-held LCD game from Nintendo’s Game & Watch and related lines is supported in MAME, with Donkey Kong Hockey bringing up the rear. Also of note is the Bassmate Computer fishing aid, made by Nintendo and marketed by Telko and other companies, which is clearly based on the dual-screen Game & Watch design. The steady stream of TV games hasn’t stopped, with a number of French releases from Conny/VideoJet among this month’s batch. For the first time ever, games running on the Barcrest MPU4 video system are emulated well enough to be playable. Titles that are now working include several games based on the popular British TV game show The Crystal Maze, Adders and Ladders, The Mating Game, and Prize Tetris. In a clear win for MAME’s modular architecture, the breakthrough came through the discovery of a significant flaw in our Motorola MC6840 Programmable Timer Module emulation that was causing issues for the Fairlight CMI IIx synthesiser. In the same manner, the Busicom 141-PF desk calculator is now working, thanks to improvements made to Intel 4004 CPU emulation that came out of emulating the INTELLEC 4 development system and the prototype 4004-based controller board for Flicker pinball. The Busicom 141-PF is historically significant, being the first application of Intel’s first microprocessor. Fans of classic vector arcade games are in for a treat this month. Former project coordinator Aaron Giles has contributed netlist-based sound emulation for thirteen Cinematronics vector games: Space War, Barrier, Star Hawk, Speed Freak, Star Castle, War of the Worlds, Sundance, Tail Gunner, Rip Off, Armor Attack, Warrior, Solar Quest and Boxing Bugs. This resolves long-standing issues with the previous simulation based on playing recorded samples. Colin Howell has also refined the sound emulation for Midway’s 280-ZZZAP and Gun Fight. V.Smile joystick inputs are now working for all dumped cartridges, and with fixes for ROM bank selection the V.Smile Motion software is also usable. The accelerometer-based V.Smile Motion controller is not emulated, but the software can all be used with the standard V.Smile joystick controller. Another pair of systems with inputs that now work is the original Macintosh (128K/512K/512Ke) and Macintosh Plus. These systems’ keyboards are now fully emulated, including the separate numeric keypad available for the original Macintosh, the Macintosh Plus keyboard with integrated numeric keypad, and a few European ISO layout keyboards for the original Macintosh. There are still some emulation issues, but you can play Beyond Dark Castle with MAME’s Macintosh Plus emulation again. In other home computer emulation news, MAME’s SAM Coupé driver now supports a number of peripherals that connect to the rear expansion port, a software list containing IRIX hard disk installations for SGI MIPS workstations has been added, and tape loading now works for the Specialist system (a DIY computer designed in the USSR). Of course, there’s far more to enjoy, and you can read all about it in the whatsnew.txt file, or get the source and 64-bit Windows binary packages from the download page. (For brevity, promoted V.Smile software list entries and new Barcrest MPU4 clones made up from existing dumps have been omitted here.)
