task spooler is a Unix batch system where the tasks spooled run one after the other. The amount of jobs to run at once can be set at any time. Each user in each system has his own job queue. The tasks are run in the correct context (that of enqueue) from any shell/process, and its output/results can be easily watched. It is very useful when you know that your commands depend on a lot of RAM, a lot of disk use, give a lot of output, or for whatever reason it's better not to run them all at the same time, while you want to keep your resources busy for maximum benfit. Its interface allows using it easily in scripts. 

For your first contact, you can read an article at linux.com, which I like as overview, guide and examples (original url). On more advanced usage, don't neglect the TRICKS file in the package.

Synonym is a small utility tool to find synonyms directly from the command line.

It’s been known for years now that SSH servers can (and should) be hardened by removing weak default algorithms. For example, recent versions of OpenSSH ship with algorithms suspected of being back-doored by the NSA (i.e.: ECDSA with the NIST P-curves), along with other algorithms with sub-128bit security levels.

But did you know that client software can be hardened too?
Why Harden Client Software?

In a world where all servers are properly hardened, there would be no need to re-configure client software. However, server hardening is unfortunately more rare than it should be, and you can only do it for machines you directly control. In that case, it’s very useful to upgrade your client’s defaults so you have assurance that only strong connections will be made.

Terminal Phase is a side-scrolling shoot-em-up in the Gradius and R-Type tradition, but in text mode. In the terminal! It's free software created by Christopher Lemmer Webber [Patreon].

Collection of random scripts that make my life in the Linux console way simpler.

Do not expect readability, stability, compatibility, portability, applicability, or survivability.

Most of them are just a verbatim dump of what I'm using on my system(s). Simply sharing them to give back to the community. Written in shell, bash, python, and even php.

K9s provides a terminal UI to interact with your Kubernetes clusters. The aim of this project is to make it easier to navigate, observe and manage your applications in the wild. K9s continually watches Kubernetes for changes and offers subsequent commands to interact with your observed resources.

Unified access to the best community driven cheat sheets repositories of the world.

Let's imagine for a moment that there is such a thing as an ideal cheat sheet. What should it look like? What features should it have?

Concise — It should only contain the things you need, and nothing else.
Fast — It should be possible to use it instantly.
Comprehensive — It should contain answers for every possible question.
Universal — It should be available everywhere, anytime, without any preparations.
Unobtrusive — It should not distract you from your main task.
Tutoring — It should help you to learn the subject.
Inconspicuous — It should be possible to use it completely unnoticed.

Such a thing exists! It's easy to install and there's even auto-complete.

Consistent security controls and high reliability are common expectations for any systems administrator. How do you deliver both on a network with thousands of servers supporting thousands of engineers? Most off-the-shelf solutions require a compromise in at least one of these areas — and we refused to accept this.

Most systems administrators use the industry-standard Secure Shell (SSH) for accessing systems, and yet many of its special features are not widely leveraged. At Facebook, we take advantage of those features to use SSH in a way that is reliable, secure, and manageable. SSH, more specifically OpenSSH, has a great way to provide both the security and reliability we require: signed certificates with principals.

Automatically show a cheat sheet or notes for any command focused in tmux. e.i. Show vim, zsh, tmux notes/key-combos in a pane when using them.

If you want your list to be included on awesome, try to only include actual awesome stuff in your list. After all, it's a curation, not a collection.

But what is awesome?
Only awesome is awesome
Research if the stuff you're including is actually awesome. Only put stuff on the list that you or another contributor can personally recommend. You should rather leave stuff out than include too much.

OProfile has been around for decades, and for some time was the workhorse of performance profiling on Linux®-based systems, and can serve the same role today. However, OProfile is not included in Red Hat Enterprise Linux (RHEL) 8 beta, and so it may be prudent for OProfile users to start considering alternative tools. Analogous projects which compare very favorably to OProfile in features, ease-of-use, and vitality of the community do exist. One such project is the Linux perf command. Until recently, when compared to OProfile, perf had some drawbacks such as lack of support for Java™ just-in-time (JIT) compiled programs and hardware event mnemonics, but these have been addressed in recent releases. This tutorial offers current OProfile users a roadmap for transitioning from OProfile to perf.

lab interacts with repositories on GitLab, including creating/editing merge requests, issues, milestones, snippets and CI pipelines.

The development team has focused on keeping lab a simple and intuitive command line interface for commands provided in the GitLab API. lab's aim is to provide GitLab users an experience similar to the GitLab WebUI with respect to errors and messages.

Product professionals (whether designers, PMs, or developers) would do well to take away the same lesson: we ask too much of our tools. Doing perfect Agile will not produce good software, but that’s not Agile’s fault.

A lot of people ask me, what should we use instead? My answer is always: use your brain.
