    Your question reminded my immediately about one of my favorite 35c3 talks Butterbrotdosen-Smartphone - Mein DIY-Smartphone-Bau from 2018-12-29. It is in German language, but has an English translation, too. Maybe it can give you some good starting ideas?

    Story, Translated with DeepL.com (free version)

    I would like to show you how I built a smartphone from a Raspberry PI. The problems and difficulties I encountered and the solutions I found. The project is not yet finished, there are still a few small things missing. Nevertheless, I want to show you my smartphone in the practical sandwich box and tell you how it came about.

    I had no idea that building a smartphone could be so complicated. Raspberry Pi + touch display is not all there is to think about in this project. At the moment, the smartphone project lives in a sandwich box and attracts attention on the subway. If the power bank can passthrough, that’s an advantage, I’ve found. Setting up the X and Y axes on the touch display so that you can also use the on-screen keyboard was not so easy. And I had to realize that Landscape is not the right size to work smoothly. Most Linux programs are not directly touch-compatible or require too much memory. Then there were also big challenges! Learning to solder was one of them. First learning how to solder, then learning how to desolder, and then daring to use the PI. I would like to tell you these and other stories about building my smartphone.








  • Looks like a really nice and useful initiative.

    Suggestion to the owners of the SFD webpage

    I would appreciate the SFD initiative even more, if on the SFD webpage you would “live by your own words”.

    Facebook and the blue bird are by no means free software, also not according to your definitions “free to study [how the program works]”, “free to distribute [copies]”, “free to modify [the software]”, “free to access [the source code]”.

    So why not at least show the benefits and use FOSS social media alternatives in action?
    If you need the momentum of the unfree social media, you still could do this additionally.




  • If you are unhappy with suggested XSane, but only want an OSS solution, I do not know a good alternative.

    Possible non-OSS solution

    Although I am an open source enthusiast, there are few application where I use commercial, even non-OSS solutions on Linux. One of this exceptions is for scanning.

    Background: I “administrate” some legacy Epson scanners used with my family’s Linux boxes and got them all to run with a software called VueScan, with the following restrictions:

    • Perfection 3490 worked out of the box, no drivers required
    • Perfection 3170 requires Epson drivers (iscan_2.10.0-2_i386.deb, iscan-plugin-gt-9400_1.0.0-2_i386.deb), but only runs on 32bit Linux
    • Perfection V30 requires Epson drivers (scan-gt-f720-bundle-2.30.4.x64.deb.tar.gz) and simply works on 64bit Debian

    As you see, it might be a bit of luck, if a device works out of the box or not.

    Unfortunately your Epson Stylus SX435W seems not to be listed under the supported Epson devices (click red button “All drivers” to see all supported Epson scanners).

    If you happen to find no solution, I suggest to use the trial version of VueScan and check if your Epson simply runs or not.

    EDIT: sorry, I forgot to mention. that the VueScan GUI has plenty of those processing options you are searching for.



  • Let the religious shell wars begin … again

    Only right answer is of course TCSH. Not much documentation and support, ancient but still receives new bugs in 2021 (on Debian), but attackers hate it! (I love it)

    My real suggestion is to learn zsh and fish (and bash). Try using them for all your purposes and in the end you will automatically find the one (or more of them) that suits you best and that you like most for your daily tasks.









  • We have purchased a very cheap Epson EcoTank ET-2815 about a year ago and it has earned its price already. Please note that this printer is for sure not a good Photo-printer, but it is fast and colorful enough for our needs. The printer is really “cheap” in a sense of dubious material (thin plastic) and bad design (e.g. compared to my ancient HP LaserJet). But it has the EcoTank, which means the color refill does not cost very much.

    Also on the positive side it did immediately work attached to my Raspi print server, after adding it with CUPS and the following settings:

    We can print from all PCs and mobile devices to it with no issues. Never have tried to scan from Linux with it (it is printer-scanner-copier)
