Jemm is an "Expanded Memory Manager" (EMM), based on the source of FreeDOS' Emm386. It should work with MS-DOS and compatible DOSes, including FreeDOS. Like other EMMs it uses extended memory to simulate expanded memory (EMS) according to EMS v3.2 and EMS v4.0. Can load drivers and resident programs into UMB (upper memory blocks) to free up core memory. Can map RAM to the video address segments A000-AFFF and B000-B7FF. Installs VCPI (Virtual Control Program Interface) services to allow DOS applications running in V86-mode to switch to protected mode. VCPI also implements a simple memory manager. Installs a VDS (Virtual DMA Service) API to give drivers/applications some control over DMA and physical addresses in V86-mode.
There are 2 versions of Jemm:
- Jemm386: standard version which needs an external eXtended Memory Manager (XMM; examples: Himem[S]X, MS Himem, XMGR ) to be loaded.
- JemmEx: extended version which has an XMM already included.
JemmEx most likely is the better choice because it will need less DOS memory than an external XMM + Jemm386.
Keychain helps you to manage SSH and GPG keys in a convenient and secure manner. It acts as a frontend to ssh-agent and ssh-add, but allows you to easily have one long running ssh-agent process per system, rather than the norm of one ssh-agent per login session.
This dramatically reduces the number of times you need to enter your passphrase. With keychain, you only need to enter a passphrase once every time your local machine is rebooted. Keychain also makes it easy for remote cron jobs to securely "hook in" to a long-running ssh-agent process, allowing your scripts to take advantage of key-based logins.
If your workflow is such that you have one terminal window but multiple tabs, this will fix quite a few annoyances.

Works very well on Linux, I've been using it for years. Also works on OSX; it's in Homebrew.
An extremely fast Python package and project manager, written in Rust. A single tool to replace pip, pip-tools, pipx, poetry, pyenv, twine, virtualenv, and more. Installs different versions of side by side Python and allows quickly switching between them. Sometimes it's as simple as throwing uv in front of the usual commands you'd run.
Handy if the system you're working on is on the older side and you can't update the version of Python available. Kind of like rvm, but for Python. Cross platform, available for just about everything you're likely to use. Can even be installed with pip.
Works at the project level, the user account level, and the venv level.
What started as just a simple tool for managing Nvidia GPUs from command line or in text mode evolved into a project that now lives up to it's Blissful designation! I present to you "Blissful Nvidia Tool" - a lovely little tool for admining your modern (Maxwell or higher should be supported) Nvidia GPU from the command line on Linux. It only requires Python3 and pynvml/nvidia-ml-py and up to date drivers. It's capable of over and underclocking, changing power limits, controlling fans, and has a nice little curses based monitor built in capable of nearly realtime monitoring of GPU status with support for saving and loading profiles! It also supports fully offline operation meaning it can be called in scripts and the like. You accept ALL responsibility for the use of this tool. Monitoring can be done as any user but overclocking control requires root. License is MIT.
Duperemove is a simple tool for finding duplicated extents and submitting them for deduplication. When given a list of files it will hash their contents on an extent by extent basis and compare those hashes to each other, finding and categorizing extents that match each other. Optionally, a per-block hash can be applied for further duplication lookup. When given the -d option, duperemove will submit those extents for deduplication using the Linux kernel FIDEDUPRANGE ioctl, which only applies to btrfs and xfs.
Duperemove can store the hashes it computes in a 'hashfile'. If given an existing hashfile, duperemove will only compute hashes for those files which have changed since the last run. Thus you can run duperemove repeatedly on your data as it changes, without having to re-checksum unchanged data.
Requrires kernel v3.13 or later.
It's in the Arch extra package repository.

Ghostfolio is an open source wealth management software built with web technology. The application empowers busy people to keep track of stocks, ETFs or cryptocurrencies and make solid, data-driven investment decisions. The software is designed for personal use in continuous operation.
In theory you can self-host it. It looks like another case of picking apart the Dockerfile.
A shell script which checks your home directory for unwanted files and directories. When it encounters a file it knows about, it will tell you whether it's possible to move this file to an appropriate location, and how to do it.
Automatic CPU speed & power optimizer for Linux based on active monitoring of laptop's battery state, CPU usage, CPU temperature and system load. Ultimately allowing you to improve battery life without making any compromises.
One of the problems with Linux today on laptops is that CPU will run in unoptimized manner which will negatively reflect on battery life. For example, CPU will run using "performance" governor with turbo boost enabled regardless if it's plugged in to power or not.
Issue can be mitigated by using tools like indicator-cpufreq or cpufreq, but these still require manual action from your side which can be daunting and cumbersome.
Using tools like TLP can help in this situation with extending battery life but it also might come with its own set of problems, like losing turbo boost. With that said, I needed a simple tool which would automatically make "cpufreq" related changes, save battery like TLP, but let Linux kernel do most of the heavy lifting. That's how auto-cpufreq was born.
Please note: auto-cpufreq aims to replace TLP in terms of functionality and after you install auto-cpufreq it's recommended to remove TLP. If both are used for same functionality, i.e: to set CPU frequencies it'll lead to unwanted results like overheating. Hence, only use both tools in tandem if you know what you're doing.

OpenEMC is an open-source firmware implementing an embedded management controller (EMC) on an STM32F1 microcontroller. It consists of a bootloader and firmware (both written in Rust) and Linux kernel driver modules (written in C).
Implements communication with the host over I2C and one interrupt line, field-upgradable firmware, full power control, a system watchdog, a real-time clock (RTC) with alarm and system wake-up, GPIO with interrupts, pin control, an analog digital converter (ADC), and full Linux device tree integration.
pipx is a tool to help you install and run end-user applications written in Python. It's roughly similar to macOS's brew, JavaScript's npx, Linux's apt, and Ruby's rvm.
It's closely related to pip. In fact, it uses pip, but is focused on installing and managing Python packages that can be run from the command line directly as applications.
pip is a general-purpose package installer for both libraries and apps with no environment isolation. pipx is made specifically for application installation, as it adds isolation yet still makes the apps available in your shell: pipx creates an isolated environment for each application and its associated packages.
By default, pipx uses the same package index as pip, PyPI. pipx can also install from all other sources pip can, such as a local directory, wheel, git url, etc.
OpenCVE lets you search the CVE you want filtered by vendor, product, CVSS or CWE. Synchronized with the feed provided by the NVD. So each CVE displays the standards you already know (CVE, CPE, CWE, CVSS). You can then subscribe as many vendors or products as you want, and you will be notified as soon as a CVE concerning them is published or updated. Your custom dashboards and reports only include the CVEs associated with your subscriptions, and you can filter the list by keywords of CVSS score. OpenCVE keeps track of the changes, so you can find the history of your alerts in your Reports page. Can be self-hosted if you're concerned about leaking information outside of your organization.
