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.

Memory leak proof every C program
I have a much better and oracti al solution: https://github.com/LibreDWG/libredwg/blob/7d9fc3da44bbdb60a4...
free is way too slow if not needed, so detect valgrind via its API. Just on valgrind to the unnecessary free dance. ASAN's memleak detector is disabled via its env.
Perl5 does its final destruction similarly, only when it has important destructors (like IO, DB handles and such) to call.

Ask HN: What are some interesting examples of Prolog?
I use it for reverse engineering unknown struct layouts for DWG classes. A field packing problem.
I'm using picat, a better Prolog dialect, and generate the facts automatically from C to generate the field layouts via picat automatically.

optimization problems as in compilers are extremely natural in Prolog.

Backdoor in upstream xz/liblzma leading to SSH server compromise

oss-fuzz: https://github.com/google/oss-fuzz :
> We support the libFuzzer, AFL++, and Honggfuzz fuzzing engines in combination with Sanitizers, as well as ClusterFuzz, a distributed fuzzer execution environment and reporting tool.
> Currently, OSS-Fuzz supports C/C++, Rust, Go, Python, Java/JVM, and JavaScript code. Other languages supported by LLVM may work too. OSS-Fuzz supports fuzzing x86_64 and i386 builds.

Fuzz Testing Is the Best Thing to Happen to Our Application Tests
I love fuzzing as a technique and use it quite regularly, but running AFL++ on even a single program occupies all threads of a high end AMD server for weeks. I'm running it locally so only paying for the electricity. If it was a cloud instance it would cost a small fortune. I think this is a reason it is not used more widely.
I will note that Google have a programme for doing fuzz testing on open source projects using computer from their cloud: https://google.github.io/oss-fuzz/

Java Fuzzing with Jazzer compared to Symflower
We will explore how Jazzer is used to automatically generate malicious inputs for Java programs, and how it compares to Symflower, which can automatically generate unit tests to uncover bugs and errors in your code. With the help of Jazzer, many bugs - some of them even in the OpenJDK - were found already. Also, as of March 2021, Jazzer is officially part of OSS-Fuzz, Google's cloud fuzzing engine. It should be noted that Jazzer is a pure "bug detection" utility that finds reproducers for errors in user code. Symflower can do the same, but provides additional functionalities to boost developer productivity, like generating high coverage unit tests and providing test templates for the software developer or tester.
What are some alternatives?
LibreCAD - LibreCAD is a cross-platform 2D CAD program written in C++17. It can read DXF/DWG files and can write DXF/PDF/SVG files. It supports point/line/circle/ellipse/parabola/spline primitives. The user interface is highly customizable, and has dozens of translations.
AFLplusplus - The fuzzer afl++ is afl with community patches, qemu 5.1 upgrade, collision-free coverage, enhanced laf-intel & redqueen, AFLfast++ power schedules, MOpt mutators, unicorn_mode, and a lot more!
FreeCAD - This is the official source code of FreeCAD, a free and opensource multiplatform 3D parametric modeler.
