  • Introducing ESP32-C5: Espressif’s first Dual-Band Wi-Fi 6 MCU

    ESP32-C5 packs a dual-band Wi-Fi 6 (802.11ax) radio, along with the 802.11b/g/n standard for backward compatibility. The Wi-Fi 6 support is optimised for IoT devices, as the SoC supports a 20MHz bandwidth for the 802.11ax mode, and a 20/40MHz bandwidth for the 802.11b/g/n mode.

  • Compulab’s new IoT gateway is based on NXP’s i.MX.8M processor and runs on Linux, MS Azure IoT and Node RED [Ed: Compulab should shun spyware from Microsoft. Bad neighbourhood.]

    The IOT-GATE-IMX8PLUS is an IoT gateway made by Compulab that is based on the NXP i.MX.8M Plus System on Chip (SoC) for commercial or industrial applications. The device features dual GbE ports, Wi-Fi6/BLE 5.3 support, LTE 4G, GPS and many optional peripherals.

    Compulab’s new IoT gateway provides support for two processor models, the C1800Q and the C1800QM. Both come with a real time processor but only the C1800QM includes the AI/ML Neural Processing Unit. 

  • Want A Break From Hardware Hacking? Try Bitburner

    If you ever mention to a normal person that you’re a hacker, and they might ask you if you can do something nefarious. The media has unfortunately changed the meaning of the word so that most people think hackers are lawless computer geniuses instead of us simple folk who are probably only breaking the laws meant to prevent you from repairing your own electronics. However, if you want a break, you can fully embrace the Hollywood hacker stereotype with Bitburner. Since it is all online, you don’t even have to dig out your hoodie.

  • Split Audio Files into Parts

    I recently got in the need of splitting quite large amount of audio files into smaller equal parts. The first thought that came to my mind was – probably thousand or more people had similar problem in the past so its already solved – so I went directly to the web search engine.

    The found solutions seem not that great or work partially only … or not work like I expected them to work. After looking at one of the possible solutions in a bash(1) script I started to modify it … but it turned out that writing my own solution was faster and easier … and simpler.

    Today I will share with you my solution to automatically split audio files into small equal parts.

  • A Previous Sibling Selector

    In natural language, what I wanted was: “select every

    element that directly precedes an <hr> element and style the <a> link inside of it.”

    I know how to select the next sibiling of an element with div + p.

    And I know how to select any adjacent sibling of an element (which follows it) with div ~ p.

    And I learned how to select an element when it only has one child with p:only-child a (even though they are the only element on their line, markdown will wrap the [link](#) elements in a paragraph tag).

    But how do I select the previous sibling of an element? Something like p:before(hr) which would select all paragraphs that precede an <hr> element.

  • Make a temporary file on Linux with Bash | Opensource.com

    When programming in the Bash scripting language, you sometimes need to create a temporary file. For instance, you might need to have an intermediary file you can commit to disk so you can process it with another command. It's easy to create a file such as temp or anything ending in .tmp. However, those names are just as likely to be generated by some other process, so you could accidentally overwrite an existing temporary file. And besides that, you shouldn't have to expend mental effort coming up with names that seem unique. The mktemp command on Fedora-based systems and tempfile on Debian-based systems are specially designed to alleviate that burden by making it easy to create, use, and remove unique files.

  • How to Add Your Own Custom Color in LibreOffice - Make Tech Easier

    While writing or editing text in LibreOffice, there are times where you need to change the color of the text or the background. LibreOffice comes with its own set of color palette that you choose the color from and it is easily accessible from the toolbar. The problem is that if you want to use a custom color which is not available in the palette, you are out of luck because there are no visible options for you to add your own color to the palette.

  • How to Split Vim Workspace Vertically or Horizontally

    There is no better computing environment than the one availed by a Linux operating system distribution. This operating system environment gives its users a complete computing experience without too much interaction with the GUI (Graphical User Interface). The more experienced you are with Linux the more time you spend on the Linux command-line environment.

    The command-line environment is efficient enough to handle OS-centered tasks like file editing, configuration, and scripting. A command-line text editor like the Vim editor makes it possible to perform such tasks.

  • How to Create AWS VPC Peering in same account/region using Terraform

    Amazon VPC peering enables the network connection between the private VPCs to route the traffic from one VPC to another. You can create VPC Peering between your own VPC with the VPC in the same region or a different region or with other VPCs in a different AWS account in a different region.

    AWS create peering connection by using the existing infrastructure of the VPC. VPC peering connection is not a form of gateway or VPN connection. It helps to make easy to transfer the data from VPC to VPC.

    In this guice, it is assumed that the VPCs that you want to peer have been created. If you need help creating a VPC checkout this guide. We need to create the peering request from the peering owner VPC, accept the peering connection request in the accepter account and update the route tables in both the VPCs with entries for the peering connection from either side.

  • How to Install Darktable on Ubuntu 22.04 LTS - LinuxCapable

  • How to Create a Sudo User on Fedora Linux

    Fedora Linux is not a new name in the world of computing. This Linux operating system distribution has Red Hat as its primary sponsor. Red Hat made its development possible via the Fedora Project. Through free and open-source licenses, Fedora hosts a variety of distributed software.

    This Linux distribution also functions as an upstream for the Red hat Enterprise Linux Community version. The latter statement implies that the Fedora Project is a direct fork for Red Hat. In other words, Red Hat directly borrows its features’ implementation from Fedora.

Pinta is a great all-around image editor in every artist’s toolkit.

  • History of Version Control Systems: Part 1

    First-generation version control systems made collaboration possible, but it was painful. Deleting, renaming, or creating new files wasn't easily done. Tracking files across multiple directories as part of one project was impossible. Branching and merging were confusing. Locks worked by copying a file with read-only or read-write UNIX permissions. Inevitably, programmers didn't want to wait for someone else to finish editing, so they got around the lock system with a simple chmod.

    The two widely used first-generation version control systems were SCCS and RCS.

  • Easily Get 3rd-Party Software on Ubuntu With Deb-Get

    Deb-get is a high-level software installation and management tool that works on top of the apt package manager to easily enable installing 3rd-party software.

    The developers of the utility have already identified a list of where most common 3rd-party applications are distributed, and they have simply programmed their utility to download software from these places and install them for you automatically, so that you don’t have to do it by yourself.

    You can check that list here.

    The usage syntax is quite simple. Just like apt, you can run commands like deb-get install, deb-get show, deb-get search and deb-get remove.

    If the 3rd-party application you are looking for is distributed in a Deb package repository, then that repository will be added to your system so that you can receive updates anytime you run the apt upgrade command. Otherwise, you will just need to run the deb-get upgrade command to update all your 3rd-party installed applications whenever there is a new version.

  • Understanding jq's SQL style operators JOIN and INDEX

    In this post I explore a couple of new (to me) operators in jq's arsenal: JOIN and INDEX, based on an answer to a question that I came across on Stack Overflow.

    The answer was in response to a question (JQ: How to join arrays by key?) about how to merge two arrays of related information. I found it interesting and it also introduced me to a couple of operators in jq that I'd hitherto not come across. There's a section in the manual titled SQL-Style Operators that describe them.

Review: AlmaLinux OS 9.0

Filed under
Reviews

Looking back on my experiences with AlmaLinux, there was such a lot of ground covered in under a week and with such varied results. Getting started was a painful experience. The release announcement for AlmaLinux OS 9.0 talks about multiple editions which do not (at the time of writing) exist, cutting off avenues of testing live media and running the distribution on Raspberry Pi computers. The torrent I tried to download was incomplete and there are some key pieces of documentation missing that I had to find upstream. To make matters worse, Anaconda is one of the least friendly graphical installers I have used in recent years with awkwardly placed controls and overly complicated screens.

Once I was up and running, there were several problems on the desktop side of things. GNOME on Wayland is relatively slow and had some problems compared to the GNOME on X11 session, automatic updates are slow and interrupt the flow of using the system. It feels like a functional step backwards to be using a Windows-like update system which is less convenient than virtually any other Linux distribution of the past two decades. To top it off, I couldn't get the Totem player to play videos (despite the software centre claiming I had the proper codecs) and VLC wouldn't play sound, though it works fine on other distributions on the same hardware.

I'm sure some people will write to me to point out AlmaLinux is not primarily intended to be used as a workstation platform, its main duty is as a server distribution. I agree with this idea, but the project claims (inaccurately, it seems) to offer live desktop editions of AlmaLinux and the system installer has multiple workstation and "Server with GUI" roles we can select. Running as a desktop system might not be the distribution's primary role, but it is one which is advertised and encouraged. Running GNOME is even the default role selected by Anaconda, so it would be foolish to overlook how the distribution functions in this, its default role.

Linux 5.19-rc4

Filed under
Linux

So we've had a couple of fairly small rc releases, and here we finally
start to see an uptick in commits in rc4. Not what I really want to
see in the middle of the release cycle, but not entirely surprising
considering how quiet it's been so far.

And while 5.19-rc4 is a bit larger than previous rc's, and is a bit
larger than we usually see at this point, it's by no means anywhere
near record size. So more of a "a bit bigger than usual" than a "Oh my
God, this thing is huge".

The changes are also spread out fairly widely, and nothing really
stands out. I think the individually biggest patches are the reverts
to the printk threading changes that people wanted to really think
about some more, since the changes had caused some issues. The rest of
the diffstat is _fairly_ flat, with perhaps the vc4 drm patches
standing out a bit.

So at least right now this all feels like "making up for a small rc3"
rather than anything really worrisome, and probably just a result of
timing some of the patches shifted into rc4. But let's see how this
develops over the next couple of weeks.

The full shortlog with all the details is below, and I don't think
there's any larger pattern here. We've got all the usual architecture
fixes, driver fixes all over the place, and filesystems, core
networking, and tooling (perf and selftests). A lot of the changes
here are one- and few-liners.

Please do go test. Thanks,
                  Linus

FSFE Information stand at Veganmania MQ

Filed under
Misc

From 3rd to 6th June 2022 happened the Veganmania street festival at the Museumsquartier in Vienna. Despite not happening for two years due to the Corona pandemic this over the years has developed into the biggest vegan street event in Europe with tens of thousands visitors everey day. Of course there have been plenty of food stands with all kinds of climate and animal friendly delicious meals but the festival had also many stands for buying other stuff. In addition many NGO tents were there too to inform about important issues and their work.

Like already tradition for many years also the local volunteers group manned an FSFE information stand from Friday noon until Monday night. It was exhausting because only two volunteers manned the stand. But we both stayed there the whole time and the interest of so many people had confirmed once more how well we optimized our information material assortment without losing the ability to bring everything at once using just a bicycle.

The front of our stall was covered with a big FSFE banner while the sides are used for posters explaining the four freedoms and GnuPG email encryption. (We very soon need to replace our old posters with more durable water resistant paper since the old one has gotten rather worn down and doesn’t look very sleek any more with all the tape pieces it is hold together.) In addition we use a small poster stand we built ourselves with just two wooden plates and a hinge. This was of left over material from a DIY center. Unfortunately this time we didn’t have any wall behind us where we would have been allowed to put any posters or banners on.

    But that script changed when Red Hat Inc. announced its In-Vehicle Operating System in partnership with General Motors Co. during the Boston event. The impact of the deal with GM was hard to miss. RHEL, as a key resource that has driven enterprise computing for over 20 years, has now become a key element in one of the most personal of use cases — the safety and performance of cars.

    “This is a pivotal moment for the transportation industry and the technology industry to come together,” said Francis Chow, vice president and general manager, In-Vehicle Operating System and Edge, during a media briefing at Red Hat Summit. “It is built upon the strong heritage of RHEL.”

  • How to approach sustainability in IT operations [Ed: Mindless, facts-free greenwashing by LF]

    Sustainability has become a priority in all aspects of a business, and IT operations is no exception. To manage energy efficiency and be climate conscious, IT ops teams must look closely at where and what is using the most energy -- and a major offender is Kubernetes clusters.

    But many teams don't know how to measure pod energy use or overall energy consumption.

    At the Linux Foundation Open Source Summit, Huamin Chen, senior principal software engineer at Red Hat, and Chen Wang, research staff member at IBM, led a session on how to approach and implement sustainability in container environments to help cut unnecessary energy use.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
