Using adb tools in Linux to remove bloatware from my Samsung Galaxy Note 20 Ultra

, 13/06/2021 | Source: Fitzcarraldo's Blog

Samsung included a lot of bloatware on my Galaxy Note 20 Ultra 5G, and it is not possible to uninstall it using Play Store. However, it is possible to remove this stuff using adb tools. I got rid of the bloatware I don’t want very easily using the Linux version of the adb tools. I […]

Is Gentoo Linux an anachronism?

, 29/05/2021 | Source: Fitzcarraldo's Blog

When I started visiting the Gentoo Linux discussion forums in 2007 there were at least three pages of posts daily, if not more. These days there is usually one page. I’m sure the number of Gentoo Linux users has dropped significantly since then. Interest in the distribution has certainly decreased since its heyday: Google Trends […]

That's the end.

So.. the time has come..

I've used to think that the one of the last bastions of purism and quality in linux world will live in gentoo. Most distributions have different contraptions that, let's say, gives more trouble underground with a problem costumed of a solution. Then the systemd arrived and make this even bigger. Fine, gentoo offer the choice of systemd, it was a matter of not using at all (even so, at this day, openrc is the default option). Then, in the last years something was happening that wasn't good. I had to change meaningful things in the system to work as expected, but that's another subject.

Then they deleted consolekit because "everyone expects elogind". Cmon.. elogind is just a band-aid because you're lazy to not patch things to work as expected. I don't see a single fucking reason to ditch consolekit. And elogind brings a different animal to the scenario, you don't have systemd but you have the systemd problems, customed as "just elogind, so the modern software will work properly", say that to the BSD userland then.

Last weeks I've noticed that portage have a new "thing" now: git-r3 is acting different and is undocumented what changed, but changed, and to the worst aspect. I don't want to talk about that because I gave up explaining this shit over and over. 

My wild guess is that they'll link bin and sbin to /usr/bin and /usr/sbin too? 

The simplicity and functionality of Gentoo has fallen. There's no such thing of seriousness on this, it's just a children's desktop playground. There's not even consistency anymore, so after those last 20 years, it's time to let it go.

Review of an MT-ViKI 2-port automatic KVM switch

Three years ago I bought a two-port KVM (keyboard, video and mouse) switch with the intention of using it to connect my keyboard and monitor to my headless server to investigate a boot-up problem. But I found the cause of the problem quickly and never needed to use the KVM switch, which was sitting on […]

Configuration of the APC UPS Daemon on my Linux server

  For obvious reasons my Linux home server supplying NAS and Web services 24/7 is connected to a UPS. The UPS model (now discontinued) I use is a 700VA 230V APC Back-UPS ES-BE700G-UK. It is connected to one of the server’s USB ports via an APC-supplied cable so that the server can interrogate the UPS […]

How to prevent CUPS omitting the bottom of the CUPS Printer test page

This is something that has been bugging me for years but I never bothered to look into it until now. When I set up a printer using CUPS Administration and then print a test page, for some printers the bottom of the test page image is cut off, as shown in the scanned image below. […]

Resurrecting my Iomega Zip 100 parallel-port drive – Linux comes to the rescue

, 19/04/2021 | Source: Fitzcarraldo's Blog

Back in 1998 I purchased what was then a state-of-the-art storage medium: an external Iomega Zip 100 drive, which used removable 100 MB ‘SuperFloppy’ disks. Until 2002 I backed up my important files on removable Zip 100 MB disks. Over several years in the 1990s Iomega released various models of the Zip 100 MB drive: […]
