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.

Show HN: Tetris, but the blocks are ARM instructions that execute in the browser
OFRAK Tetris is a project I started at work about two weeks ago. It's a web-based game that works on desktop and mobile. I made it for my company to bring to events like DEF CON, and to promote our binary analysis and patching framework called OFRAK.
In the game, 32-bit, little-endian ARM assembly instructions fall, and you can modify the operands before executing them on a CPU emulator. There are two segments mapped – one for instructions, and one for data (though both have read, write, and execute permissions). Your score is a four byte signed integer stored at the virtual address pointed to by the R12 register, and the goal is to use the instructions that fall to make the score value in memory as high as possible. When it's game over, you can download your game as an ELF to relive the glory in GDB on your favorite ARM device.
The CPU emulator is a version of Unicorn (https://www.unicorn-engine.org/) that has been cross-compiled to WebAssembly (https://alexaltea.github.io/unicorn.js/), so everything on the page runs in the browser without the need for any complicated infrastructure on the back end.
Since I've only been working on this for a short period of time leading up to its debut at DEF CON, there are still many more features I'd eventually like to implement. These include adding support for other ISAs besides ARM, adding an instruction reference manual, and lots of little cleanups, bug fixes, and adjustments.
My highest score is 509,644,979, but my average is about 131,378.
I look forward to feedback, bug reports, feature requests, and strategy discussions!

It Takes 6 Days to Change 1 Line of Code
Entails hundreds of hours of single-stepping through that opcode in Linux kernel using an indirect operand pointing toward its own opcode (self-modifying code).
Even the extraordinaire Fabrice Bellard (author of QEMU) admitted that it is broke and did a total rewrite, which fixed tons of other issues.

Vita3K android running Tales of Hearts R - A Glimpse of What's to come
Macdu (Vita3K dev) also stated that this game is CPU bound so they used a CPU emulator known as unicorn2 , this is also the reason for the slow speed

QEMU Version 7.0.0 Released
This is how I found out a snippet of assembly code that can actually distinguished between a KVM hypervisor and most of today’s emulator.

Top Python Tools for Malware Analysis. – PythonStacks
Unicorn is missing from that list.
The python CPU emulator with full program counter (PC) and general (and other CPU-specific) register set controls.
I use it to catch fileless malware in the second fastest dynamic manner. Also good for detecting Rowhammer/SPECTRE behaviors.

Seeking information to build software to support windows software apps to run on upcoming Snapdragon X Elite arm processor?
The open-source and performant ones are https://fex-emu.com/ and https://box86.org/, but they are not written in Rust. Their documentation is probably the best bet if you want to build something along these lines.

Have you ever tried to run STEAMCMD on a Beaglebone Black ?
On the official repo if you scroll down there is steam compatibility and it says that in the root of the repo there is the steam install script. https://github.com/ptitSeb/box86
- Wine on chromebook
-
Steam not available ?
That means it'll need a 32-bit emulator to run on, but as it says on box86.org, box86 only runs on 32-bit ARM chips. Hence it runs on a Pi2 but not a Pi3 or higher.

Factorio on Arm: A Benchmark
Recently, I got a server from Oracle Cloud, having 4 cores and 24GB of RAM. Then, using a software called Box86 and its 64 bit version called Box64, I succeeded in running Factorio! Unfortunately, 1.1.80 ran at 3 UPS! I went through each major version, testing each individual one down to 0.12. Here are my results!

Does my white thinkpad count~?
Unfortunately box86 requires a little-endian processor, and the G4 is a big-endian processor so it won’t work
