Instalando #antix virtual para hacer algunas prácticas con runit, me encuentro con esto durante el proceso de instalación:

Configurar zram como swap al inicio... justo lo que comenté en mi último video en el canal de youtube de #juncotic.

Eso sí, crasheó con la instalación y tuve que desactivarlo para instalar y activarlo después, pero bueno, que aparezca ahí es muy bueno! 🙂

Reminder: enable ZRAM on your Linux system to optimize RAM usage (and potentially save money)

With the price of RAM getting out of control, it might be a good idea to remind Linux users to enable ZRAM so they can get better performance without upgrading memory, or save money on their next single board computer by selecting a board with the right amount of memory. I had already written about the subject when I enabled ZRAM on a ODROID-XU4Q in 2018 using zram-config, and did the same on my Ubuntu laptop at the time. In recent days, I found Firefox crashing often due to running out of memory on my system with 16GB of RAM, and the Linux 7.0 release reminded me about ZRAM, since there were some related changes. So I decided to check the current swap configuration on my Ubuntu 24.04 laptop: lzo doesn't look like a recent compression algorithm, and I think I've seen Zstandard compression used on other systems before. However,

Se viene un #debian virtualizado para seguir jugando con cositas del núcleo, memoria, #zram, #zswap, #hardening y #optimización 🙂

#optimizacion_linux #linux #gnu

To tackle the #RAM issue i keep having on #Linux, I'm giving #zram another try :)) except this time, I'm adding that while retaining my existing swapfile, and I'm also disabling #zswap (as I have before). will see how it goes

Qué interesante debate se armó en el último video que publiqué en le canal de YouTube de #juncotic! 🤗

Con una comentarios así se enriquece mucho la comunidad, y se aprende un montón! ✨

Si no vieron el video, les dejo el link, digo, por si alguien quiere jugar con #zram, #swap y cositas del núcleo #Linux 😃

Linux 7.0 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just released Linux 7.0 on LKML: The last week of the release continued the same "lots of small fixes" trend, but it all really does seem pretty benign, so I've tagged the final 7.0 and pushed it out. I suspect it's a lot of AI tool use that will keep finding corner cases for us for a while, so this may be the "new normal" at least for a while. Only time will tell. Anyway, this last week was a little bit of everything: networking (core and drivers), arch fixes, tooling and selftests, and various random fixes all over the place. Let's keep testing, and obviously tomorrow the merge window for 7.1 opens. I already have four dozen pull requests pending - thank you to all the early people. Linus This follows the Linux 6.19 release about two months ago, which brought us PCIe link encryption and

Les discussions sur #zswap et #zram reviennent souvent, voici un article intéressant sur la question.

Debunking zswap and zram myths

zswap and zram are fundamentally different approaches with different philosophies. If in doubt, use zswap.

I've been trying to figure out how to address/work around #Linux 's hunger for RAM and non-ideal/insufficient controls around this. I remembered seeing an article by #KDE about them trying to address this themselves on their new distro and stumbled upon this issue they created - pertaining to topics like #Zram, #Zswap, etc.

It's great to see that this issue is acknowledged for once instead of the constant stream of Linux
extremists swearing that it's not an issue, or somehow it being an issue is an attack to them and their beloved OS/distro/DE. Also it's always a suspicion I have but even in this short issue thread, it's clear that Linux people (hence, devs) are often only familiar with #Windows (and #Android), so the benchmark is always them - which isn't a problem 'cept they both suck ass (in a lot of aspects but esp this topic on RAM usage/OOM handling).

I'm glad to see at least one comment mentioning how
#Apple does it on #macOS (maybe also #iOS) - which offers a far superior experience and is exactly why 8 freaking GB RAM on a #Mac or 4GB RAM on an #iPhone is no big deal at all (plenty, even), unlike on other systems/platforms. It's high time for Windows to die so our beloved Linux devs look at Apple instead for benchmark/inspirations. It doesn't help ofc that macOS can easily be insufferable to use when ure already on Linux land, but I promise it won't even be close to half as shitty as Windows, and there def are alot of things we could learn/benefit from and replicate.

¡Para los que se lo perdieron! ☕️🐧

¿Tu #Linux anda lento o querés cuidar la vida útil de tu SSD?

Tenés que conocer #ZRAM.

En este video les explico cómo crear dispositivos virtuales comprimidos directamente en la RAM.

Es una de las mejores formas de optimizar el Swap y las cachés del sistema sin gastar un peso en hardware.
