At the core of every Linux system is the kernel. The kernel is what sets apart Linux from other operating systems. It is the central component of the operating system and acts as a bridge between the user-level applications and the underlying hardware components.
In conclusion, Linux can be a viable option for businesses that want to take advantage of its cost savings, customization options, security features, and reliability. However, it is important to carefully consider the compatibility and support issues that may arise, as well as the limited user base, when deciding whether Linux is the right choice for your organization. It may be necessary to weigh the benefits and disadvantages of Linux against those of proprietary operating systems in order to determine the best fit for your business. Ultimately, the decision to use Linux in your business will depend on your specific needs and goals.

MongoDB offers high-performance data storage when deployed over multiple servers. So, we need to identify the version of MongoDB running in the system when analyzing the reported problems. The version numbers which follow a semantic numbering scheme enable us in recognizing significant and minor changes. We can run the latest bug-free version by just updating the mongodb version which should be known. We have discussed some methods below which can be used to determine what version of MongoDB we are currently utilizing. Some of these techniques check the server version of the MongoDB, whereas others check the version of the Mongo shell.

The Logical Volume Manager commands in Linux are one of the handiest tools I’ve used for adding new disk or expanding existing volumes. It’s easy to do this on the fly without requiring downtime or rebooting, though I always recommend taking a full backup of all data on any existing volumes first, as well as taking a snapshot of the virtual machines involved.
Apache’s mod_proxy module allows you to forward requests to another server using the ProxyPass and ProxyPassReverse directives. However, in some cases, you may want to exclude certain URLs from being proxied. In this tutorial, I will show you how to exclude an URL from ProxyPass in Apache.
The first step is to identify the URL that you want to exclude from being proxied. For this tutorial, let’s assume that we want to exclude the URL “/static” from being proxied.

At this time, ChatGPT is the talk of the town.
I was doing some preparation for my weekly tutoring activity and when I realized I misspelled “science” on a particular file that I end up sharing with parents. Somehow, I spelled “scoence” and almost published the file spelled as such. I realized that somewhere along the line, Dolphin, the most amazing file manager wasn’t doing the spell check that it once did for me. A crutch I much appreciate leaning on to keep me from looking like a fool.
I did a quick search about spellcheck in dolphin but nothing came up in the top few search results. The full documentation came about but that wasn’t helpful. What I wanted to answer was, how can Dolphin, once again spell check my file names.
Here is the answer: Go into the Plasma System Settings and search for “Spell Check.” That will filter out the module from the rest quickly. The option of “Automatic spell checking enabled by default” is what you need to have Dolphin automatically check your spelling.
We are excited to announce the launch of our new website, now built with the popular static site generator, Hugo. This change marks a significant shift away from our previous CMS, Drupal, and brings a fresh new look that aligns with the style of KDE, our parent organization.

Additionally, the new design is fully responsive, ensuring that the site looks great on any device.
Netrunner is one of my absolute favorite Linux distributions, but I haven’t been recommending it to people lately. Why? Well, to be honest, I thought the operating system was dead. You see, the last time the developers released a new version of Netrunner was early 2021. I assumed development had ended. The year 2022 came and went without any substantial Netrunner news.
But no, Netrunner lives! Out of the blue, a new version of the KDE-focused operating system is made available for download. Code-named "Vaporwave" (no, not vaporware), Netrunner 23 is based on Debian 11 "Bullseye" stable for the first time. Yes, fans of Netrunner can finally have modern Debian.
After nearly two years of silence regarding the operating system's development, you would expect a rather detailed announcement, but nothing could be further from the truth. Shockingly, we are treated to only two substantive sentences, which we share below.

Ubuntu is a Linux distribution based on the Debian operating system. Xubuntu is an operating system that is based on Ubuntu, but using the Xfce desktop environment instead of GNOME. Freespire is an OS that is based on Xubuntu. What does this mean? Well, besides too many Linux distributions existing, it means Freespire is, very loosely speaking, sort of like the great-grandson of Debian.
Anyway, today, Freespire 9.0 becomes available for download. A 64-bit ISO of the Linux-based operating system, can be had immediately. It is notable for using Xfce 4.18.
"Today the PC/OS Open Source development team is pleased to announce Freespire 9.0, our newest release based on Canonical;s Xubuntu 22.04 LTS. With stability and functionality in mind, our team has been working to make this optimal for both open source enthusiasts and desktop users," explains The Freespire Team
Welcome to the Ubuntu Weekly Newsletter, Issue 771 for the week of January 15 – 21, 2023.
The companies state the “highest performance RISC-V development board” is a “premium software development system ideal for developer desktop machines and rack-based build/test/deploy servers for RISC-V software development. RISC-V has no limits.”. But last October, the demo platform was clocked at 2.2 GHz, and if what we have here is indeed a quad-core Cortex-A75 processor @ 2.2 GHz, it will be the fastest RISC-V platform and offer a performance boost compared to the VisionFive 2 SBC (which I received yesterday), but still be ways behind mid-range Arm and entry-level x86 processors such as Rockchip RK3588 or Intel Jasper Lake processors.
We don’t have pricing information yet, but it’s clearly designed as a (Linux) development board that’s NOT optimized for cost, so the microATX motherboard won’t be cheap and should cost several hundred dollars, and possibly closer to $1,000. For reference, the previous generation HiFive Unmatched mini-ITX motherboard initially sold for $665. You may find a few more details and/or register your interest on the product page.

If you frequent driving ranges, you’ve probably seen a machine (often attached to the front of an armored golf cart) designed to pick up golf balls. Because a driving range can easily fill up with thousands of golf balls an hour, such machines are necessary. After noticing that nobody wanted to pick up the ping pong balls after matches, Maxime Monsieur and his team (Oumaima Achkif, Reda El Marsse, and Amir Farbod) built this robot that collects ping pong balls using a mechanism similar to those used for golf balls.
Like a golf ball collecting machine, this robot picks up golf balls using a spinning mechanism that resembles something you’d see on an agricultural harvester. Any ping pong balls in front of the robot get pushed towards that mechanism by a pair of spring-loaded arms. The rotating mechanism then pushes the ping pong balls up a ramp and into a bin. The robot navigates through the room like an old robot vacuum: by driving forward until it meets a wall, then turning in a random direction.

Meta is the parent company of Facebook and Instagram, that is one of the biggest techno-feudal oligarchs of our time. The General Data Protection Regulation (GDPR), of the European Union is the “the toughest privacy and security law in the world”.
Says the Guardian that Ireland’s Data Protection Commission (DPC) has just given Meta “three months to bring its data processing operations into compliance with [the decision to impose] a fine of €210m for the Facebook GDPR breach and €180m for Instagram.”
The problem is that all this software-enabled revolution still needs:
more batteries than may be ever produced
more grid than it may be feasible
space, need, money by the same numbers of car owners of today
Last weekend I had the pleasure of being on a Scout camp. I am part of
a team taking a group of 14-18 year olds on an Explorer Belt
expedition to Malta, an island nation in the Mediterranean. The aim of
the Explorer Belt is to spend 10 days completing 10 minor and 1 major
project. This group of Explorer Scouts is made up of members of
various units across South West Birmingham and so many do not know one
another. I certainly didn't know many. So why not have a camp to get
to know one another and do some planning?
This is the third Frank Sinatra album I've had so far. This felt unreasonable, so I checked Wikipedia - and it'll be the last Frank Sinatra album I get, because he 'only' has 3 albums on the list. 3 is very respectable, but I haven't enjoyed the previous two much, so that also isn't much consolation.
Sleater Kinney passed me by totally. No good reason, I just never had the cause to pick them up. I'm grateful this project made me sit down and listen to Dig Me Out.
Oof-da I'm tired. Two misfortunes happened to me last night, the first was the 4€½ hr delay, the second was the invalid connection. Even though I had a ticket for a train that I missed because the railroad was late, there was some issue with the reservation so they couldn't compensate me or give me a reduced fare. In fact, I had to pay another $15 for the next day's train. Annoying, but I kinda expected this from America's least reliable (and only!) passenger rail.
This is a revised post of my older one talking about systemd. A lot is the same, but I've added some configuration options, and swapped to inetd because it was easier to setup, and was what efingerd expected.
If you want create a TUI or GUI application, I am not really interested in these details, even though this project is well suited to work on a TUI environment...
I found myself, always more, taking notes and ideas in GemText; I would write emails too if only we had a Gemini Email Client. Even though I'd had loved having more "lines" I think we got a good compromise. The composition for lines helps you to create a peculiar style giving a nice rhythm to the paragraphs, I really love it!
I think if I would have a software that allows me to taking notes and ideas in a Gemini fashion, and if I could link together these notes as the good old time of the hyper-texts, and moreover if I could eventually export such ideas in Gemini pages; plain text documents; or even plain text email; this will surely become my preferred software for writing anything.
The main RFC (Request For Comment)s for mDNS appear to be RFC-6762 [3] and RFC-6763 [4] and to support them in full requires breaking changes to my library. The first are a bunch of flags, defined in RFC-6762 and it affects pretty much the entire codebase. The first deals with “Questions Requesting Unicast Responses.” Most flags are defined in the header section, but for this, it's “the top bit in the class field of a DNS question as the unicast-response bit.” And because mDNS specifically allows multiple questions, it's seems like it could be set per-question, and not per the request as a whole, as the RFC states: “[w]hen this bit is set in a question, it indicates that the querier is willing to accept unicast replies in response to this specific query, as well as the usual multicast responses.” To me, that says, “each resource record needs a flag for a unicast reponse.” The other bit the “outdated cache entry” bit. which again applies to individual resource records and not to the request as a whole. And again, to me, that says, “each resoure record needs a flag to invalidate previously cached values.”
Another year, another version of Epicyon [1]. The details of changes can be found here [2]. Over the last year there have been many bug fixes and small improvements, and I have added more documentation.
Things seem to be going quite well for the fediverse in general, and there also appears to be declining mindshare in the legacy silo systems and in the scammy "web3". Open standards are making something of a comeback. The fall of Twitter may mean that activists start running their own infrastructure [3] again, and there's the potential for something like another Indymedia to emerge from the smoldering ruins.
* Gemini (Primer) links can be opened using Gemini software. It's like the World Wide Web but a lot lighter.
