  • What’s new in Security for Ubuntu 22.04 LTS?

    Canonical Ubuntu 22.04 LTS is the latest long term support release of Ubuntu, one of the world’s most popular Linux distributions. As a Long Term Support release, Ubuntu 22.04 LTS will be supported for 10 years, receiving both extended security updates and kernel livepatching via an Ubuntu Advantage subscription (which is free for personal use). This continues the benchmark of Ubuntu LTS releases serving as the most secure foundation on which to both develop and deploy Linux applications and services. In this blog post, we take a look at the various security features and enhancements that have gone into this new release since the Ubuntu 20.04 LTS release. For a more detailed examination of some of these features, be sure to check out the previous articles in this series which cover the improvements delivered across each interim release of Ubuntu in the past 2 years between 20.04 LTS and 22.04 LTS.

  • We Still Want IBM i On The Impending Power E1050

    In March last year, as Big Blue was finishing up the development of the Power10 family of Power Systems machines, we wrote an essay explaining that we wanted IBM i to be a first-class operating system citizen on the four-socket Power E1050 machine, which we finally expect to see launch on July 12 if the rumors are correct.

  • Big Blue Tweaks IBM i Pricing Ahead Of Subscription Model

    Back in May, Big Blue said that it was going to be simplifying the IBM i stack ahead of a move to subscription pricing for systems software as well as hardware that runs it. To do that means zeroing out prices for a slew of things that had price tags on them formerly.

  • Guru: The Finer Points of Exit Points

    Many years ago, we received a call from an IBM i customer stating that all exit points were gone and the QAUDJRN and receivers were missing. Then the question, “Do you think we’ve been hacked?” Truth was, the exit points weren’t gone; the associated programs had been de-registered. Conclusion, they had most likely been compromised.

  • IBM i Licensing, Part 3: Can The Hardware Bundle Be Cheaper Than A Smartphone?

    How many monthly iPhone bills is a Power10-based entry server worth?

  • Guild Mortgage Takes The 20-Year Option For Modernization

    When Kurt Reheiser returned to the IBM i server after a 15-year hiatus away the platform, things weren’t a lot different than how he left them.

  • How to Add Repository to Debian

    APT checks the health of all the packages, and dependencies of the package before installing it. APT fetches packages from one or more repositories. A repository (package source) is basically a network server. The term "package" refers to an individual file with a .deb extension that contains either all or part of an application. The normal installation comes with default repositories configured, but these contain only a few packages out of an ocean of free software available. In this tutorial, we learn how to add the package repository to Debian.

  • Making a Video of a Single Window

    I recently wanted to send someone a video of a program doing some interesting things in a single X11 window. Recording the whole desktop is easy (some readers may remember my post on Aeschylus which does just that) but it will include irrelevant (and possibly unwanted) parts of the screen, leading to unnecessarily large files. I couldn't immediately find a tool which did what I wanted on OpenBSD [1] but through a combination of xwininfo, FFmpeg, and hk I was able to put together exactly what I needed in short order. Even better, I was able to easily post-process the video to shrink its file size, speed it up, and contort it to the dimension requirements of various platforms. Here's a video straight out of the little script I put together: [...]

    And it got me thinking about what you can and can’t do — what you do and don’t have control over.

  • allow-new-zones in BIND 9.16 on CentOS 8 Stream under SELinux

    We run these training systems with SELinux enabled (I wouldn’t, but my colleague likes it :-), and that’s the reason I aborted the lab: I couldn’t tell students how to solve the cause other than by disabling SELinux entirely, but there wasn’t enough time for that.

  • Will the IndieWeb Ever Become Mainstream?

    This is an interesting question, thanks for asking it, Jeremy. I do have some history with the IndieWeb, and some opinions, so let’s dive in.

    The short answer to the question is a resounding no, and it all boils down to the fact that the IndieWeb is really complicated to implement, so it will only ever appeal to developers.

  • How to Install CUPS Print Server on Ubuntu 22.04

    If your business has multiple personal computers in the network which need to print, then we need a device called a print server. Print server act intermediate between PC and printers which accept print jobs from PC and send them to respective printers.

In this tutorial, we learn how to set up CUPS print server on Ubuntu 22.04.

Open Hardware: XON/XOFF and Raspberry Pi Pico

  • From XON/XOFF to Forward Incremental Search

    In the olden days of computing, software flow control with control codes XON and XOFF was a necessary feature that dumb terminals needed to support. When a terminal received more data than it could display, there needed to be a way for the terminal to tell the remote host to pause sending more data. The control code 19 was chosen for this. The control code 17 was chosen to tell the remote host to resume transmission of data.

  • Raspberry Pi Pico Used in Plug and Play System Monitor | Tom's Hardware

    Dmytro Panin is at it again, creating a teeny system monitor for his MacBook from scratch with help from our favorite microcontroller, the Raspberry Pi Pico. This plug-and-play system monitor (opens in new tab) lets him keep a close eye on resource usage without having to close any windows or launch any third-party programs. The device is Pico-powered and plugs right into the MacBook to function. It has a display screen that showcases a custom GUI featuring four bar graphs that update in real-time to show the performance of different components, including the CPU, GPU, memory, and SSD usage. It makes it possible to see how hard your PC is running at a glance.
