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.

Obfuscating WebAssembly using Emscripten with an LLVM-based obfuscator
Seeing as there are no WebAssembly obfuscators, I decided to try to build Emscripten with an LLVM-based obfuscator. Specifically, I built it using Hikari, which is based on the obfuscator-llvm project. This was built for research purposes and may not be practical in real-world scenarios, but I thought I'd share it here anyways!

Valve bans 40.000 dota2 accounts using honeypot patch
Love this topic. I remember Everquest used to checksum areas of memory that were commonly modified from cheats. World of Warcraft used to (possibly still does, it has been forever since I looked at this) inject anti cheat code at runtime.
Obfuscation and deobfuscation is also super interesting. I think overall reverse engineering and figuring out how things work is one of the most interesting things in computer science.

A question from a non-cheater
5- Ah, no. https://github.com/obfuscator-llvm/obfuscator/wiki but I see why you said that, I didn't mean to use shitty app to make your code harder to read, I apologise I meant changing the actual binary, use different opcodes mutate the code, etc.. like llvm obfuscator not this shit. but if I were you I would say the same since I didn't clarify this point.

Code obfuscation
the obfuscator-llvm project is a nice place to look at when introducing yourself to some fundamental obfuscation techniques like control-flow flattening and opaque predicates, which operate on top of assembly instructions and what are called basic blocks.

Kimmer: Port immer for kotlin/jvm
This problem can be resolved by https://github.com/jboss-javassist/javassist/blob/master/src/main/javassist/util/proxy/DefineClassHelper.java perfectly, I will use some of its code to fix this problem on 0.0.1
