> it slows programs down

Interesting, how costly would be hardware acceleration support for Fil-C code.

> i.MX8 is not realtime and the support for running bare metal code is very much non existent.

Looking at e.g. STM32H755: 1x Cortex-M7 480 MHz, 1x Cortex-M4 240 MHz, USB2, 100 Mbit Ethernet, DAC.

Comparing to AM6421: 1x Cortex-A53 1GHz, 2x Cortex-R5F 800MHz, 1x Cortex-M4F 400MHz, 2x PRU, USB3, 1 Gbit Ethernet, PCIe Gen2.

I can hardly believe STM32H755 microcontroller is almost so costly as AM6421 SoC.

That's why I'd say Cortex-M fits well for a very-very good soft real-time (99.99+%). But for hard real-time (100%) you need an FPGA.

I'm missing comparison of FL2 on Gen13 vs Gen12, since this would be a real win (or loss?) from the hardware upgrade. How can they justify the upgrade without this data?

> usually in the lower single percentage range

Is it worth to compare Wayland vs X11?

When I need to compare large text files I use diffuse instead of meld.

> environmental conditions

Shouldn't it be: no more negligible manufacturing / assembly tolerances instead? I mean, when I turn PC on, the temperature of all components is 20 C, the training is done at almost this temperature. But then the PC can work for months with much more higher memory controller and DRAM chips temperatures.

> apple's relatively long OS update period

For a 127 EUR Samsung A17 up to 6 OS and security updates (6 years) are advertised. For a Google Pixel up to 7 updates. How long is it for Apple?

This has been reported here but got not enough attention:

"Debian GNOME team announces intent to remove GTK 2 in Debian 14" (08.01.2026)

https://news.ycombinator.com/item?id=46548257

P.S. Still hope GNOME maintainers let other volunteers maintain GTK 2.

But since when? There are public announcements about new energy deals since summer 2024. But I'm missing any information about similar RAM/NAND/HDD deals back then, so that corresponding shortages could be only for short time until, say, summer 2026.

> add more channels

and unfortunately increase latency even more with registered DIMMs. Comparing bandwidth increase (50 GB/s) to the stagnated latency (~80..120 ns total, less than ~0.1 GB/s) over last decades, I'm wondering, whether one still can call today's RAM random memory (though sure it can be accessed randomly). Similar to hard disk drives. Up to 300 MB/s sequentially but only up to less than 1 MB/s 4KB random (read).

Considering the level of the API. But it is total opposite comparing a bit deeper. Linux has a famous rule "WE DO NOT BREAK USERSPACE!" e.g. [1].

Implemented like any custom GTK+ 2 widget?

Very nice looking UI! Powered by forked GTK+ 2 [1]. (First release almost 24 years ago [2]).

> You can’t be against the Ukraine war in Russia

I was glad after discovering [1]. In one of the videos the interviewer explains, why he was not arrested. The channel is for English-speaking auditory outside of Russia. It was enough to "close eyes" for some openly expressed critiques. Though it was painfully to listen to some people who were not against the war.

"Say" in the sense of demonstrate peacefully for this? Then I'm impressed. If someone else can confirm this? Is this because of USA being a federal union? Before Ukraine declared independence, there were voices to make Ukraine a federal state, so that people in the West part of Ukraine can live their way of life and people living 1600 km (!) away in the East and Southern parts would be not much affected from that and vice versa. Voices for the unitary state were stronger because of stability of the state. Would be interesting to see some documentary "what if", whether a federal state would be more stable against pulling from the west (Europe, US) and the east (Russia).

I'm referring to (if we would continue with the list):

- Ukraine for Donbas

Which is so much weaker than all others. There are Ukrainians, Russians, Chinese, Tibetans. But there is no such ethnicity as People of Donbas.

OTOH in a democratic state you're still have the right to demonstrate peacefully for whatever you want, even if it doesn't make much sense. But would you allowed to demonstrate in Ukraine for Donbas independence if they are considered separatists according to the law?
