You can also add OpenAlias DNS TXT record with your cryptowallets, also web monetization of another kind. https://openalias.org/

You can report viruses on TPB's forum, there's usually entire accounts which upload viruses which are easy to find.

I use Xiqi printer for barcode printing on a self-adhesive paper. It's about $11 only, battery powered, light, bluetooth.

Oh, this e-reader has lots of productivity features. You can highlight words (which are later stored in a separate folder), make bookmarks, easily translate words, use screen reader, etc. I use it mostly for work and academic papers, not fo

Well I guess that could help, but only on Windows, since it's the only OS which follows printer "installation" flow for driverless printers. Other OS just discover printer all the time, and for that they need DNS-SD as well,

Most people can't comprehend that. "If it's available publicly online and has a readme, it's DEFINITELY was created for me and for all other users, right?" This is so common, to the point that it's a FOSS misco

But that's another issue: developers make software for themselves vs "digital public goods for everyone". UI/UX (which the article is about) is part of the broader approach.

Most people don't need computer (full feature power, full power of choice) to solve their task, as could be seen with the smartphones, which are designed as appliances more or less. I don't want most of consumer electronics to

When I was working in audits, I used to record everything happening on my screen with 3 fps and then rewatching it with 10x speed, just not to forget anything. When Recall was announced, I was in minority who thought it was super cool techn

I read until "gVisor, system call emulation" and though that this is some kind of IP-KVM project port to RTOS or microcontroller or something other thing which reuses Linux code but does not run Linux.

le9 is a 'simple' method to keep the fixed amount of the page cache. It works exceptionally well for what it is, but it requires manual tuning of the amount of cache in MB. MGLRU is basically a smarter version of already existing

It's fixed since Kernel 6.1 + MGLRU, see above, or read this: https://notes.valdikss.org.ru/linux-for-old-pc-from-2007/en/...

It's kind of solved since kernel 6.1 with MGLRU, see above. Dirty buffer should also be tuned (limited), absolutely. Default is 20% of RAM, (with 5 second writeback and 30 second expire intervals), which is COMPLETELY insane. I limit i

The majority of desktop Wi-Fi cards/chipsets have buggy drivers that break mDNS discovery in one way or another. To the point that I'd say that Wi-Fi drivers are the most offender in printer discovery problems, which also rely on

Yes, it has dramatic impact on the battery life. Wi-Fi in lower power state, when it has nothing to respond to, disables power amplifier and only listens to incoming data. Some functions which are usually performed by the OS are offloaded o

It improved the battery life but made the connection activity detection worse (the disconnected phone won't be detected for up to 2 hours), but I didn't complain anymore. I initially set it to 5 minutes.

Newer Raspberries also rely on third-party components they have limited control of. VL805 USB chip in RPi 4 and 5 has known bugs since 2020 which are still not fixed.

Sleep states are not trivial from the security perspective, and they've eliminated the issue by just not allowing it :)

I used that! Nowadays we have cryptocurrency-based Sia, Storj, which are kind of similar.

Wow, that's really different compared to what we have in EU, with up to 10 SD channels in a single multiplex.
