Need a KDE and OpenSuSE expert

by ??? ###

Recent update to my Tumbleweed broke KDE. The install is on an HP laptop. I'm worried that this update will also break things on two other computers. Willing to pay reasonable fees to fix and/or advise. Thanks *--* *Let it be known that my mind is as quick, sharp and strong as a steel bear trap,* * and it is in no way my fault that it has been left out in the rain, rusting it beyond* * all practical use.*

spinlocks

by Brian E. Lavender

I was checking the kernel output messages of my Xen VM and I saw the following message. "Preventing Guests from Spinning Around" It made me think of the song "Spin me right round like a record player" Then I found the research paper "Preventing Guests from Spinning Around" https://www.researchgate.net/profile/Thomas_Friebel/publication/200014431_L… The work you have to do to keep from spinning, and spinning, and spinning! These are all entertaining thoughts. Brian -- Brian Lavender http://www.brie.com/brian/ "There are two ways of constructing a software design.

Full stack development with Srping boot and React

by Brian E. Lavender

I think the book a friend told me about was the following. Full Stack Development with Spring Boot and React by Juha Hinkula https://www.packtpub.com/product/full-stack-development-with-spring-boot-an… It appears that there is a new version of this book as well. https://www.packtpub.com/product/full-stack-development-with-spring-boot-3-… I was looking at it and it says to install node js. This is where I think I had the stumbling point. Node JS is packaged in Fedora, yet node is a package manager itsself. I seemed to become a question of getting the correct dependency version. It appears that Node Version manager is the way to go! https://developer.fedoraproject.org/tech/languages/nodejs/nodejs.html I tried the first portion of the book that has you go to the Spring IO project generator and it now targets Spring Boot 3.2.2. I imagine the code samples still have the Spring 2.0 tools. Well, that's some food for thought if anyone is interested.

Google is Bad

by Gary

I recently had occasion to use Google searches to support a brake job on my truck and a software/hardware issue with Fedora 38. God the results were amazingly bad. I got the Fedora issue fixed. The big issue with the Google results is that you can't really restrict the results to Fedora 38 only. Google wants to give me 3 million results and not the 30 I really need. You can't tell what version of Fedora a lot of the results were for and they didn't work. Even if it was a Fedora or Red Had website. I finally found a result where someone mentioned that it was the H264 codec that was the problem. Focusing on that got me the fix. Which allowed me to realize that if anyone on the Fedora team though about my use case,: the infrequent and obscure use of a web browser to stream a video, the problem never would have occurred. But that is for another rant. I'm thinking I want to do a startup for a search engine that prioritizes results that include all the search terms and appropriately implements and, not, or, and maybe shows the date the result was created or first found (some websites do this and I really like it). Maybe we could use Google's data. Maybe we could rank the results some other way than the number of times someone clicked on it or haw it fits into our ad strategy. Maybe get feedback. Maybe use AI. I did get the brake drum fixed, but mostly by using what I already knew. None of the information and YouTube videos actually provided the information necessary to successfully do the job and most left major safety issues unaddressed. The ones at the top of the results did seem to be doing a good job selling things like rust penetrants and showing how to spary them is places where they don't do any good. One of the places they said was a cover you should remove so you could spray some magic stuff was actually the cover for the star adjuster on the drum brake. This has to be manually backed off so you can remove the drum. Seeing this video reminded me that I hadn't done that. You can't pull the drum unless you do that. Nothing mentioned this step. Yet they all showed smiling happy people taking the drum off. Some with really impressive background music. You have to be careful when working the bleed nipple so that you don't get air in the cylinder. No one mentioned this. You should ckeck the level in the reservoir when you are done. In fact, one encouraged you to "just drive off, you're all done". If you had actually done the job, you would have backed off the star wheel. This is the self adjuster. It is now not adjusting and you should back up a short distance and apply the brakes firmly a few times to get it readjusted. Otherwise, you have no rear brakes when you stop -Gary

ordered X1 Carbon Gen 11 laptop with Fedora preinstalled

by Brian E. Lavender

I ordered an X1 carbon from Lenovo with Fedora preinstalled. https://www.lenovo.com/us/en/p/laptops/thinkpad/thinkpadx1/thinkpad-x1-carb… It seems that they have the hi-res screen offering with the camera that previously did not have support. It was a known issue for at least two years to avoid that hardware configuration. It looks like it is supported now! Lenovo has 45% discount promotion on their site! I configured the system with 64 Gig ram and 2 TB storage with the 2880x1800 screen. The "estimated" delivery is Feb 1. I have the 1st gen X1 Carbon and it has been a great machine!

pipewire-pulse vs pulseaudio

by Gary

Anyone played around with pipewire. I was just going to do some pacmd stuff on one of my recent Fedora 38 installs when I found out I am actually running pipewire-pulse instead of pulseaudio. It's suppose to be a seamless dropin for pulseaudio, but pacmd doesn't seem to see it. The man pages and online documentation for pipewire seems a bit sparse. -Gary
