Filed under
Software

When you work with terminals in Linux often, you’re bound to run into some struggles when you want to multitask.

That’s where the stalwart members of the Linux system administration world tmux and screen come in. But, as with all things in the open source community, the choice here isn’t clear as to which one of these commands is better for your usage.

Software: Radare2, Joplin, and Vizex

  • Explore binaries using this full-featured Linux tool

    It's natural to ask why you need yet another tool if existing Linux-native tools do similar things. Well, it's for the same reasons you use your cellphone as your alarm clock, to take notes, as a camera, to listen to music, to surf the internet, and occasionally to make and receive calls. Previously, separate devices and tools handled these functions — like a physical camera for taking pictures, a small notepad for taking notes, a bedside alarm clock to wake up, and so on. Having one device to do multiple (but related) things is convenient for the user. Also, the killer feature is interoperability between the separate functions.

    Similarly, even though many Linux tools have a specific purpose, having similar (and better) functionality bundled into a single tool is very helpful. This is why I think Radare2 should be your go-to tool whenever you need to work with binaries.

  • Use Joplin to find your notes faster

    To store my digital notes, I needed to pull them all into one place. The tool needed to be accessible from multiple devices, have a useful search function, and be able to export or share my notes. I chose Joplin after trying many, many different options. Joplin lets me write notes in markdown, has a pretty good search function, has applications for all the OSs (including mobile), and supports several different ways to sync between devices. As a bonus, it has folders and tags, so I can group my notes together in ways that make sense to me.

  • Welcoming Open Web Docs to the MDN family [Ed: Mozilla outsourcing to Microsoft is a colossal mistake]

    Collaborating with the community has always been at the heart of MDN Web Docs content work — individual community members constantly make small (and not so small) fixes to help incrementally improve the content, and our partner orgs regularly come on board to help with strategy and documenting web platform features that they have an interest in.

    At the end of the 2020, we launched our new Yari platform, which exposes our content in a GitHub repo and therefore opens up many more valuable contribution opportunities than before.

    And today, we wanted to spread the word about another fantastic event for enabling more collaboration on MDN — the launch of the Open Web Docs organization.

  • find mostly doesn't need xargs today on modern Unixes

    For usage with find, all of this is unnecessary on a modern Unix and has been for some time, because find folded this into itself. Modern versions of find don't have just the traditional '-exec', which runs one command per file, but also an augmented version of it which aggregates the arguments together like xargs does. This augmented version is used by ending the '-exec' with '+' instead of ';', like so: [...]

  • Linux fmt Command – Formatting Text on the Command Line

    The fmt command is a text utility included in the GNU Core Utilities. It was originally created to format email messages at the command line. However, it can be very useful for reading any text files in the terminal. Sure, modern terminals will wrap text to fit in the window.
