De moins en moins d'écrans CRT fonctionnent et c'est normal, les composants s'usent notamment les condensateurs. Beaucoup d'écrans ont été jetés et ça devient de plus en plus rare d'en trouver alors si possible ne les jetez pas, vendez-les ou donnez-les pour pièces.

Tech is political.
You encode your values, your attitude and your bias into the code.
The tech you create can give you legitimacy. It can give you influence. Get rich enough (or start out rich enough) you get doors opened to you.
It's all power.
We can see what some people in tech do with that power.
We can however choose to not contribute to that enablement.
You're in FOSS you've made some sacrifices.
What's a little more?

Never Forgive Them
In the last year, I’ve spent about 200,000 words on a kind of personal journey where I’ve tried again and again to work out why everything digital feels so broken, and why it seems to keep getting worse, despite what tech’s “brightest” minds might pr…Edward Zitron (Ed Zitron's Where's Your Ed At)

By that time we were able to stop using the 1, but it was still "local long distance" for a few years after that, at least. I have no idea when the area started requiring 10 digit dialing because I had stopped using a land line by early 2007.
I can't talk about phone switching without sharing the "Speedy Cutover Service" video from the 80s.

@f4grx I will make some burning this week. I can "take orders" if some of you wants. Lets say I can book a total of 10 blank slate coasters for mastodon people.
I need a picture B&W (or vectorized) for ~9x9cm (the tile is 10x10cm but the hammered edges prevents nice result)
I propose 4€ each (without postage cost, to be added depending where you live).
First come, first served.

Well if vince fires up the laser again I'd be interested!

Coding is being positioned as place where generative AI is going to have a huge impact.
But a new study of 800 developers found GitHub Copilot did little to improve productivity, while introducing 41% more bugs into the code.

Alan Turing didn't have our modern boolean circuit notations, so he described circuits by the minimum number of high input lines required to trigger an output. You can almost see it as a neural net rather than logical gates, except when the ≢ sign appears for XOR. The lines with zeroes written over the node outlines are inhibitors.
The semicircles are delays measured in bits, which (as this was a serial machine) can achieve all sorts of shifting and rotation operations. The rectangles are delay lines (mercury tanks designed by Tommy Flowers at the Post Office research centre in Dollis Hill), and the number inside indicates the number of bits cycling around (although in some pages it's the number of 32-bit words, confusingly). Smaller delay lines could buffer a word for combination in a future operation.

@grs cause this was the speed it actually ran at back at the day.
(also, until very recently, there was legal limits on how fast I could transmit data over amateur radio in the US)
Hamnet news:
New 35 mile link and repeater brought up on the regional network thanks to involved parties.
I'm implementing dark mode on our dashboard so our users with browsers in their car can display the call log without being hindered by light in the night. A few nuts and bolts need to be adjusted with the map, but we're almost there.
@Foxarc in the PQC discussion, it is about switching key agreement and key signing (a lower priority) away from weaker cryptographic technologies (which today are computationally-hard, but in a post quantum world are no longer considered computationally-hard) in less than 10-20 years.
If you can call a software transition over 10 years agile..
It is also about making things easier to switch, should the newer tech introduced suddenly have weaknesses that were previously unknown, such as SIDH.
While at a high level it sounds like "great, I can just swap parts" as better ones come, the truth is that these PQC technologies have different protocol level requirements, storage and communication sizes, as well as computational overhead far different than what we have today, and change is fundamentally difficult to have backwards compatibility for.

in reply to aki-nyan • • •Still waiting for someone to make an x86 platform that just shoves uboot and/or a kernel/initramfs, plus a DTB, into SPI flash and just boots straight from that without needing any "firmware" at all.
Like how ~all ARM SoC boards boot.
aki-nyan
in reply to Andrew Zonenberg • • •@azonenberg That could be neat.
I remember this whole "linux booting linux" thing that made some noise *years* ago and I think it shared that idea, can't recall though.
Everything should just standardize on OpenFirmware :v

in reply to aki-nyan • • •@azonenberg flat device trees aren't cute. Device trees are only flat when they are stressed.
Basically, the idea that you need a DTB to boot is wrong. The device tree needs to be provided by the firmware. We went through this with ACPI already, people replacing their broken tables on the command line, and it had not suddenly become a sensible strategy twenty-five years later.
Andrew Zonenberg
in reply to Simon Richter • • •@GyrosGeier it makes much more sense to have a data driven boot process and not have code running on the platform before the OS starts.
(Doing this right would of course require that things like RAM init be handled in silicon or by the kernel, which is a whole other can of worms where silicon vendors are concerned...)
Simon Richter
in reply to Andrew Zonenberg • • •@azonenberg exacty — also, DTBs don't know how much RAM you have, the board revision, ... It's just unmanageable for users.
RISC-V, in the spec, say that the DRAM init code shall deliver a device tree to any later stages, with the hardware inventory hardcoded,
In practice, I need U-Boot specifically to patch the broken device tree. If it were correct, I could use Linux directly after the DRAM init code.
Andrew Zonenberg
in reply to Simon Richter • • •@GyrosGeier > how much ram
Isn't that the whole point of SPD (since PCs ~always used DIMM/SODIMM based memory)? You just need some board-independent init code that reads the eeprom from each slot, figures out how much is there, and brings it up.
I don't see why you need per-board firmware when the entire point of the eeprom is discoverability.
