• AVML - Acquire Volatile Memory for Linux - LinuxLinks

  AVML is an X86_64 userland volatile memory acquisition tool written in Rust, intended to be deployed as a static binary.

  AVML can be used to acquire memory without knowing the target OS distribution or kernel a priori. No on-target compilation or fingerprinting is needed.

  This is free and open source software.

• makeself - make self-extractable archives - LinuxLinks

  The makeself.sh script itself is used only to create the archives from a directory of files. The resultant archive is actually a compressed (using gzip, bzip2, or compress) TAR archive, with a small shell script stub at the beginning. This small stub performs all the steps of extracting the files, running the embedded command, and removing the temporary files when done. All the user has to do to install the software contained in such an archive is to “run” the archive, i.e sh nice-software.run. I recommend using the “.run” (which was introduced by some Makeself archives released by Loki Software) or “.sh” suffix for such archives not to confuse the users, so that they will know they are actually shell scripts.

  makeself is cross-platform software. It’s free and open source.

• Infer - static analyzer for Java, C, C++, and Objective-C - LinuxLinks

  Regardless of the input language (Java, Objective-C, or C), there are two main phases in an Infer run:

  The capture phase – Compilation commands are captured by Infer to translate the files to be analyzed into Infer’s own internal intermediate language. The analysis phase – In this phase, the files in infer-out/ are analyzed by Infer. Infer analyzes each function and method separately. If Infer encounters an error when analyzing a method or function, it stops there for that method or function, but will continue the analysis of other methods and functions. So, a possible workflow would be to run Infer on your code, fix the errors generated, and run it again to find possibly more errors or to check that all the errors have been fixed.

• dnst - Domain Name System Tools - LinuxLinks

  dnst is intended to offer both:

  a supported drop-in (see below) replacement and upgrade path for a subset of the popular NLnet Labs LDNS example tools, re-implemented in the Rust prpgramming language powered by the NLnet Labs domain Rust library an evolving toolbox of commands to aid DNS operators in the maintenance and operation of their zones and nameservers.

• InvoicePlane - self-hosting invoicing for freelancers and small businesses - LinuxLinks

  The main idea behind the InvoicePlane software is the creation of an application you host on your own server and use it for basic invoicing and client management. The target groups are freelancers, self-employed workers and small to medium sized companies which need a reliable and easy to use invoicing system but who can’t afford an expensive software.

  This is free and open source software.

• TUISIC - simple TUI online music streaming software - LinuxLinks

  TUISIC’s billing intrigued me. Its developer claims that the software is the first of its kind. A bold statement. So what’s TUISIC? It’s a simple TUI online music streaming application written in C++ with vim keybindings.

  The software streams music from a wide range of sources: YouTube, ForestFM, LastFM, SoundCloud, and JioSaavn. The developer indicates that support for YouTube Music is in the pipeline.

• Iocaine - defense mechanism against unwanted scrapers - LinuxLinks

  Originally, iocaine started as a garbage generator, a tarpit, a place where the reverse proxy routed unwanted visitors, so that they’d crawl an infinite maze of garbage. Since then, it grew into a more ambitious project, and includes a scripting engine that lets the iocaine-operator tell the software how to treat each incoming request. The idea remained similar, however: to waste crawler resources, while keeping costs down.

  Unlike some similar tools, iocaine does not try to make the bad bots go away, it welcomes them, into an infinite maze of garbage. It does so, because the author observed that if the bots keep being served plausibly legit looking content, they will behave slightly better: they will not try to disguise themselves as much, and they’ll keep a steady, but not overwhelming crawling pace. Serving unwanted visitors junk also evoked warm, fuzzy feelings inside the author. He likes warm, fuzzy feelings. The garbage generator used in iocane has been tuned with this in mind, to make it cheap, pretty much on par with serving a static file.
