    ext4magic project has been in deep sleep for 10 years and is now changing to abandoned. During this time, around 30 releases of the dependent e2fsprogs and library have been released. These changes are not reflected in the current ext4magic code, so current file systems are no longer compatible with ext4magic. User feedback shows that ext4magic can no longer successfully process current ext4 file systems. The clear recommendation to users is: please do not use ext4magic, it will no longer work correctly. For the packers in the various distributions, if you still provide packages for it, please stop supporting ext4magic as an optional package for your distribution. Otherwise you will only raise false hopes in users who have just had a data accident, and this tool can no longer live up to these hopes

    BrazilFW Firewall and Router

    BrazilFW Firewall and Router

    A powerful network security tool, easy, safe and totally free.

    BrazilFW is a mini Linux distribution designed to be used as a Firewall and Router that runs easily on older computers. An old PC running BrazilFW is much more powerful and efficient than commercial software for routing in offices and residences running on a "powerful" computer. BrazilFW is based on Coyote Linux, which was designed by Joshua Jackson who discontinued Coyote Linux in version 2.24 in August 2005. In that same month comes on the scene BrazilFW Firewall and Router (BFW) with version 2.24, which is led by "Claudio" and "Marcelo - Brazil", running only on floppy disks, and being 2.30.1 the last version with this support . The following versions, as well having automatic detection of network cards, only run on large capacity media, such as hard disk (HD). Versions in Development: * 2.33.x: Uses kernel 2.4.x and is developed by Marcinho Samurai. * 3.x: Uses kernel 4.x and is developed by WoshMan

    ESP8266Audio

    ESP8266Audio

    Arduino library to play MOD, WAV, FLAC, MIDI, RTTTL, MP3

    Arduino library for parsing and decoding MOD, WAV, MP3, FLAC, MIDI, AAC, and RTTL files and playing them on an I2S DAC or even using a software-simulated delta-sigma DAC with dynamic 32x-128x oversampling. ESP8266 is fully supported and most mature, but ESP32 is also mostly there with built-in DAC as well as external ones. For real-time, autonomous speech synthesis, check out ESP8266SAM, a library that uses this one and a port of an ancient format-based synthesis program to allow your ESP8266 to talk with low memory and no network required. All this code is released under the GPL, and all of it is to be used at your own risk. If you find any bugs, please let me know via the GitHub issue tracker or drop me an email. The MOD and MP3 routines were taken from StellaPlayer and libMAD respectively. The software I2S delta-sigma 32x oversampling DAC was my own creation and sounds quite good if I do say so myself.

    Expat

    Expat

    Fast streaming XML parser written in C99 with >90% test coverage

    Welcome to Expat, a stream-oriented XML parser library written in C. Expat excels with files too large to fit RAM, and where performance and flexibility are crucial. There are a number of applications, libraries, and hardware using Expat, as well as bindings and 3rd-party wrappers. Expat is packaged everywhere. This is Expat, a C99 library for parsing XML 1.0 Fourth Edition, started by James Clark in 1997. Expat is a stream-oriented XML parser. This means that you register handlers with the parser before starting the parse. These handlers are called when the parser discovers the associated structures in the document being parsed. A start tag is an example of the kind of structure for which you may register handlers.
