    gojq

    Pure Go implementation of jq

    ...I understand this might cause problems for some scripts but basically, we should not rely on the order of object keys. Due to this limitation, gojq does not have the keys_unsorted function and --sort-keys (-S) option. gojq supports arbitrary-precision integer calculation while jq does not; jq loses the precision of large integers when calculation is involved.

    Surrogates.jl

    Surrogates.jl

    Surrogate modeling and optimization for scientific machine learning

    A surrogate model is an approximation method that mimics the behavior of a computationally expensive simulation. In more mathematical terms: suppose we are attempting to optimize a function f(p), but each calculation of f is very expensive. It may be the case we need to solve a PDE for each point or use advanced numerical linear algebra machinery, which is usually costly. The idea is then to develop a surrogate model g which approximates f by training on previous data collected from evaluations of f.

    Funkin

    Funkin

    A rhythm game made with HaxeFlixel

    ...The project includes the full game source built using Haxe and OpenFL, allowing contributors and modders to explore and extend the game mechanics, audio library, and visual assets. In the core game loop, players navigate a story across multiple weeks with unique songs and characters, and the engine handles input timing, score calculation, and animated feedback in sync with background music. Because it’s open source, the community has created an expansive ecosystem of mods, new songs, and custom charts that extend replayability far beyond the base content. The repository itself is designed to be approachable for new developers who want to learn game development or contribute to the project, with build scripts, asset pipelines, and documentation to help users compile the game locally.

    Evolver

    The GEP-Powered Self-Evolution Engine for AI Agents

    ...The project uses a protocol-constrained approach centered on concepts such as genes, capsules, and events, which are stored as structured assets and selected through signal matching logic. It also depends on Git as part of its operating model, using repository state for rollback, blast-radius calculation, and solidification workflows, which makes it especially relevant for code-centric agent environments. The CLI integrates with external agent runtimes through setup hooks, including support for platforms such as Cursor, where hooks can fire at specific lifecycle moments like session start or after file edits.

    FiniteDifferences.jl

    FiniteDifferences.jl

    High accuracy derivatives, estimated via numerical finite differences

    FiniteDifferences.jl estimates derivatives with finite differences. See also the Python package FDM. FiniteDiff.jl and FiniteDifferences.jl are similar libraries: both calculate approximate derivatives numerically. You should definitely use one or the other, rather than the legacy Calculus.jl finite differencing, or reimplementing it yourself. At some point in the future, they might merge, or one might depend on the other.

It's much simpler and maintainable. The calculation for height of complex UITableViewCell is really boring. With FlexLib, all the calculation is automatically. FlexScrollView (the subclass of UIScrollView) can manage its contentSize automatically. I'm sure it will save you a lot of time.

    A simple measure of dependency freshness

    ...Rails 5.0.0 (June 30, 2016) is roughly 1 libyear behind 5.1.2 (June 26, 2017). There are obviously more nuanced ways to calculate dependency freshness. The advantage of this approach is its simplicity. You will be able to explain this calculation to your colleagues in about 30s. If your system has two dependencies, the first one year old, the second three, then your system is four libyears out-of-date. At Singlebrook we try to keep our client’s apps below 10 libyears. We regularly rescue projects that are over 100 libyears behind. "lib" is short for "library", the most common form of dependency. ...
