Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Good iPad games like Heroes 3?
idos2 is still available via patreon (https://litchie.com/dospad) - and really good as I purchased it when it was available from the appstore, alternatively any dos emulator via altstore - then heroes II... it's by far the best experience you can have on ipad/iphone. Tried many clones and while some are OK, heroes II blows them all away.

DOS emulator
there was idos 2 available, but sadly was pulled out from sale (ofc because of apple) and if you didn't purchase it back then - now you can't. Now the only two ways without jailbreaking are: 1) https://litchie.com/dospad - via patreon the idos2 dev sign up the newest version for you
- iDOS ipa file?
- Mobile Battle Station for some holiday Pascal coding

Looking for iDOS IPA
AFAIK this is the latest IPA available on GitHub: https://github.com/litchie/dospad

Copying files in dospad on iOS?
This seems to be a bug/feature (depending how you look at upgrades breaking existing features). I filed https://github.com/litchie/dospad/issues/139 to track this.
- Installing games in iDOS 2

One of my favorite DOS games when I was younger. Now running on my iPad Pro through sideloaded iDOS via AltStore. Loads of fun on a touchscreen and super convenient to play during meetings :)
I’m doing all of this through iDOS (which is just a DOSBox variant compiled for iOS/iPadOS devices). I don’t own an Android tablet, but a quick search shows multiple versions of DOSBox available on the Google Play store you could install on your Android device. Once installed, there is usually a way to drop DOS game files into a folder accessible by DOSBox as a drive mount. You CD to the directory and run the game.

[Question] Any good gaming emulators for iOS 14?
Also for MS-DOS games in general, iDOS is an awesome Dosbox emu for iOS. Supports Bluetooth keyboards and MT32 emulation and a bunch more.

QEMU Version 9.0.0 Released
My most-wanted QEMU feature: https://github.com/qemu/qemu/commit/a2260983c6553
Using `gic-version=3` on macOS you can now use more than 8 cores on ARM chips.

Autoconf makes me think we stopped evolving too soon
A better solution is just to write a plain ass shell script that tests if various C snippets compile.
https://github.com/oilshell/oil/blob/master/configure
https://github.com/oilshell/oil/blob/master/build/detect-pwe...
Not an unholy mix of m4, shell, and C, all in the same file.
---
These are the same style as a the configure scripts that Fabrice Bellard wrote for tcc and QEMU.
They are plain ass shell scripts, because he actually understands the code he writes.
https://github.com/qemu/qemu/blob/master/configure
https://github.com/TinyCC/tinycc/blob/mob/configure
OCaml’s configure script is also “normal”.
You don’t have to copy and paste thousands of lines of GNU stuff that you don’t understand.

Revng translates (i386, x86-64, MIPS, ARM, AArch64, s390x) binaries to LLVM IR
> architectural registers are always updated
In tiny code, the guest registers (global TCG variables) are stored in the host's registers until you either call an helper which can access the CPU state or you return (`git grep la_global_sync`). This is the reason why QEMU is not so terribly slow.
But after a check, this also happens when you access the guest memory address space! https://github.com/qemu/qemu/blob/master/include/tcg/tcg-opc... (TCG_OPF_SIDE_EFFECTS is what matters)
But still, in the end, it's the same problem. What QEMU does, can be done in LLVM too. You could probably be more efficient in LLVM by using the exception handling mechanism (invoke and friends) to only serialize back to memory when there's an actual exception, at the cost of higher register pressure. More or less what we do here: https://rev.ng/downloads/bar-2019-paper.pdf

Multipass: Ubuntu Virtual Machines Made Easy
Some of these tools include Oracle VM VirtualBox (that I've used since before the acquisition of Sun Microsystems by Oracle), VMWare Workstation Player, and QEMU, but last year, I found out about Multipass.

Libsodium: A modern, portable, easy to use crypto library
For C/C++ projects that use meson as the build system, there is an excellent way to manage dependencies:
https://mesonbuild.com/Wrapdb-projects.html
https://mesonbuild.com/Wrap-dependency-system-manual.html
meson will download and build the libraries automatically and give you a variable which you pass as a regular dependency into the built target:
https://github.com/qemu/qemu/tree/005ad32358f12fe9313a4a0191...
https://github.com/harfbuzz/harfbuzz/tree/main/subprojects
https://github.com/harfbuzz/harfbuzz/blob/37457412b3212463c5...
Or, if you're using proper operating systems, they're managed by the usual package manager, just like everything else.

Top 6 Virtual Machine Software in 2023
For all the users of the Linux platform, QEMU is the VM that you should go for. This software comes without any price tag and works as an emulator of various machines with utmost ease and completion; the software uses dynamic translations to emulate hardware peripherals and enhances its overall performance. If you are using QEMU as a virtualizer, then it will function exactly like the host system (provided you have the right set of hardware).

UTM for Developers
In this tutorial, we set up macOS and Windows virtual machines on UTM, a macOS application that provides a GUI wrapper for QEMU, a powerful open-source emulator and virtualizer. UTM allows you to easily manage and run virtual machines without memorizing complex commands. It also has special handling for macOS, making it simpler to install compared to other virtual machine software.
