      • TecMint11 Best Screen Recorders For Linux in 2023

        Recording your desktop session is a common and good practice for a variety of purposes, such as playing a hard level of a game, creating a video tutorial, or writing a how-to article. Screen recording software can help you accomplish all of these tasks.

        In this review guide, we shall cover some of the best screen recording and live video streaming software that you can find for your Linux desktop.

      • TecMint6 Best Email Clients for Linux Systems

        Email, an enduring method of communication, remains a fundamental way to share information; however, the preference has shifted from web applications to email clients over the years

        An email client is software that allows users to manage their inbox, send, receive, and organize messages directly from a desktop or mobile phone.

      • University of TorontoA user program doing intense IO can manifest as high system CPU time

        Recently, our IMAP server had unusually high CPU usage and was increasingly close to saturating its CPU. When I investigated with 'top' it was easy to see the culprit processes, but when I checked what they were doing with the strace command, they were all busy madly doing IO, in fact processing recursive IMAP LIST commands by walking around in the filesystem. Processes that intensely do IO like this normally wind up in "iowait", not in active CPU usage (whether user or system CPU usage). Except here these processes were, using huge amounts of system CPU time.

      • David Buchanans32 Unix Clock

        It's pretty simple. The clock face has 256 "ticks" (annotated in hexadecimal), and four dials, each moving exactly 256 times slower than the previous. The longest and fastest moving dial moves at one tick per second, which means it takes very approximately 4 minutes to do a full revolution (4:16, actually). The next hand takes roughly 18 hours, the next roughly 6 months, and the smallest hand takes ~136 years - or exactly 2^32 seconds.

      • Jan Piet MensOn the importance of logging

        In spite of configuring debug logging and log forwarding from AWX, I couldn’t figure out what was wrong. My assumption was the body of the post was missing something. I looked at the source code of the api view controller and still didn’t figure it out and basically gave up after an hour. Actual webhooks posted from Gitea worked (when configured in AWX as Github), but my simple curl invocation wouldn’t. (Remind me to rave about how I like Gitea and Forgejo.)

      This report covers hrev57184 through hrev57256.

      It’s worth noting: the main Haiku CI is currently offline as the developer who was hosting the build machine moved to a location with much slower internet. A new build machine and home for the CI has already been selected, but isn’t fully online yet, so the nightly builds are a bit behind at the moment.

      To the user, an appimage is a binary that looks and feels like a statically linked binary. In fact, you’d have a hard time discovering a binary is an appimage at all.

      At its core, an appimage is a squashfs image that contains an application and all of its dependencies. Prepended to the binary is a statically linked runtime that: [...]

      • University of TorontoMy (new) simple system to open URLs on my desktop from remote Linux machines

        I have a long standing setup where I read my email on one of our Linux login servers, instead of on my desktop. Email can include URLs that I want to open, so I need some way of opening these URLs in my desktop browser. For a long time this has been through one of two options; either I forwarded X over SSH and used Firefox's X-based remote control, or I was operating purely with text and selected the URLs in the terminal to use with my tools to open URLs in various browsers.

      • Linux Links4 Best Free and Open Source Office Suites

        Microsoft Office still dominates market share of office suites. Businesses have often rejected free Office alternatives. However, things are changing. With the cost of a price subscription plan for Microsoft Office, the average home user or small business will welcome a free alternative. Fortunately, there are some truly excellent open source alternatives available for Linux (and other operating systems).

        Our recommendations are captured in our legendary LinuxLinks-style ratings chart. Only free and open source software is eligible for inclusion.

    • Education

      • Cendyne NagaSoftware Security Fur All

        The security industry is not too accessible. It focuses on common details, rather than fundamental problems and solutions. We can do better by building communities with free knowledge and compassion, rather than exclude newcomers with paywalled content and competitive hazing. Fundamentals like separating code and data must be top of mind as new technologies like large language models get deployed. Bad cryptography is everywhere and we hope to make cryptographic knowledge more accessible.

      • Daniel LemireTranscoding Unicode strings at crazy speeds with AVX-512

        In software, we store strings of text as arrays of bytes in memory using one of the Unicode Transformation Formats (UTF), the most popular being UTF-8 and UTF-16. Windows, Java, C# and other systems common languages and systems default on UTF-16, whereas other systems and most of the web relies on UTF-8. There are benefits to both formats and we are not going to adopt one over the other any time soon. It means that we must constantly convert our strings from UTF-8 to UTF-16 and back.

      • ButtondownIf you work on a big language, I'd like to talk

        Directed graphs are ubiquitous, so it's incredibly weird to me that not a single mainstream programming language has a built-in directed graph type. And it's even weirder that not a single mainstream programming language has them in the standard library.

      • Juha-Matti SantalaPull requests are great

        I have recently been seeing an increasing amount of chatter about and against pull requests. These especially often come from the crowd that advocates for pair or mob/ensemble programming. I saw a great one in Mastodon the other week but failed to save it so I can’t reference it. In essence, that toot asked: What legit benefit is there for pull requests for teams that trust each other?

        And I’ve seen this sentiment quite often: some people consider that pull requests’ main or even only function is to prevent malicious or bad code from entering a codebase from untrusted sources. And in many distributed open source projects that is one of its functions. However, I’d argue that focusing solely on the trust issue and then dismissing pull requests for teams that trust each other, is short-sighted.

      • Matt RickardThe New Economics of Generating Code

        "The next is replace -- replace feature after feature after feature of the older Cerner system with a new Cerner system, new Millennium, which we are not coding in Java like we usually do. The new Cerner system is being generated -- as you know, generative AI generates code. We have an application generator called APEX. And we are not writing code for the new Cerner; we are generating that code in APEX, and it's going extremely well."

        This is a quote from Larry Ellison in Oracle’s latest earnings call. It should be taken with a grain of salt — Ellison is a master of narrative, and he’s addressing an audience of investors. Whether APEX works as well as he claims or if developers are simply using GitHub Copilot, the fact remains: this is the future of a good chunk of software development.
