PRTG Catches Network Issues Before They Cause DowntimeReactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

sj.h
A tiny little JSON parsing library
...The library does not try to own every part of JSON handling; instead, it leaves number conversion and string interpretation to the user. This design gives developers direct control over memory, numeric precision, Unicode handling, and application-specific parsing behavior. It reports errors with line and column locations, which makes malformed input easier to debug despite the library’s small size. It is especially appealing for embedded tools, game engines, small utilities, and C projects that value transparency over abstraction. -

Double Conversion
Efficient binary-decimal & decimal-binary conversion routines for IEEE
Double Conversion is a high-performance C++ library that provides precise and efficient binary-decimal and decimal-binary conversion routines for IEEE 754 double-precision floating-point numbers. Originally extracted from the V8 JavaScript engine, it was refactored into a standalone library to make its robust number conversion algorithms easily reusable in other projects. The library ensures consistent and accurate results for converting between double values and their string... -

libvips
A fast image processing library with low memory needs
...It has around 300 operations covering arithmetic, histograms, convolution, morphological operations, frequency filtering, colour, resampling, statistics and others. It supports a large range of numeric types, from 8-bit int to 128-bit complex. Images can have any number of bands. It supports a good range of image formats, including JPEG, JPEG2000, JPEG-XL, TIFF, PNG, WebP, HEIC, AVIF, FITS, Matlab, OpenEXR, PDF, SVG, HDR, PPM / PGM / PFM, CSV, GIF, Analyze, NIfTI, DeepZoom, and OpenSlide. It can also load images via ImageMagick or GraphicsMagick, letting it work with formats like DICOM. ... -

Abscom
A C11 library of reusable data structures and platform utilities.
...On top of that it ships a Python-inspired dynamic runtime that brings var values, lists, dictionaries, sets, JSON, random utilities, and a light object system to plain C, plus a scientific layer with matrices, statistics, general math (scalar utilities, number theory, geometry, complex numbers), CSV, path helpers, and basic threading. A data science layer adds NumPy-style reshaping and generators, Pandas-style numeric CSV, functional utils, and SciKit-Learn-style preprocessing (one-hot encoding, train/test split). An AI/ML layer adds activations, softmax, MSE loss, and numerical gradients for neural-network forward passes. An ultimate layer tops the scientific stack off with computational backend selection (CPU / AVX SIMD / GPU stub), a Micrograd-style scalar autograd engine. -

headsort
headsort: streaming sort + 2x faster than gnu sort
headsort sorts files by line and fields. Options can pick field order and etc. In general headsort can sort in 1/2 the time sort(1) (mergesort) does in situations involving either pipes or mult column selection; less than 1/2 with both. Best case was about opposite that of sort(1)*. NEW* hsort main algorithm speed improvement (applies to all; 27,29,31). Now faster than sort(1) (in all cases tested). Using triangulation, hsort begins piped sorted output when 1st bin is done. ... -

flom
Free Lock Manager
...Shell commands, scripts and custom programs can be synchronized inside a single system or in a network of IP connected systems. FLoM supports different types of abstract resources: simple, numeric, set, hierarchical and transactional sequence. libflom, the library shipped with FLoM, allows you to develop your own application using a simple C, C++, Java, Perl, PHP or Python client API. SSL/TLS security for network communication, X.509 certificates for peer to peer mutual authentication. -

HyperCLIPS
CLIPS compatible application which allows a high performance execution
HyperCLIPS was designed for high performance, especially with the CLIPS program which have a great deal of numeric calculation or memory allocation, along with keeping almost full compatibility with the original version of CLIPS. You can use HyperCLIPS to run CLIPS programs with no modification. The original version of CLIPS Rule Based Programming Language is available from here. https://sourceforge.net/p/clipsrules/ The misclns4.tst is a good example for it because HyperCLIPS performs 200% - 400% faster than the original version of CLIPS. ... -

lagrange_simulation_mechanics
simulations with Lagrangian method,both symbolic and by numeric deriv
...All well-grouped in folders. there is also a 'review' in 3 demos of the Newtonian dynamics: mass-spring systems. most of progs are written in C, with use of SDL lib to display simple graphics and have real-time interactivity. As to programming complexity, it's very simple... this all aims at classical physics simulation in a simple but efficient way. The numeric stuff really just illustrate the use of a real little physics-engine aimed at articulated body simulation... that's the funnest part of it: but of course much more is coming. Also some examples in Game Maker and Matlab/Octave are coming soon. link to Part 1 of the video where all method is thoroughly exmplained: http://youtu.be/ELD0WPOxNb0 http://youtu.be/Kjhkyq-pLLw the part_2 shall explain numeric stuff, and some support for collisions and serious rigid bodies jointed. -

Free Vector Math Library
C math functions vectorized for x86_64
The goal is to provide SSE (and eventually AVX) vectorized forms of C math functions. These function calls are the basis of floating point math, and currently prevent gcc from auto-vectorizing most numeric code. I want to fix that by providing vectorized versions. Presently, the library provides vectorized forms for double precision for about half of the standard C math functions. -

Lagrange_Motocross
2D motorcycle simulator done using Lagrangian equations of motion
2D simulation game using exlusively Lagrangian equations of motion. It's a 2D motocross game similar to X-Moto, ActionSupercross and such. Some stability issues persist but mostly it's good already. I shall compile it soon for Windows: one of the problems is that Windows compilers must periodically be reinstalled, and that's annoying. Using Lagrangians in games is not a well documented thing, but it allows to achieve exellent results in very little time, soon after a good parametrization... -
