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.
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.

Working on a way to subdivide blog post content into a format that should comfortably translate into ActivityPub Notes.
Changing my content to run on an intermediary language last summer has allowed for so much flexibility in post-processing.
@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.
See, they wanted to call the DirectX -> Vulkan layer "IndirectX" but found out the term was already used for something else!
Specifically, for Indirect X Rendering over the GLX/Xorg pipeline using the LIBGL_ALWAYS_INDIRECT=1 Mesa flag to use the older indirect OpenGL renderer for remote X connections
"We have IndirectX at home" :p

COMPUTER IN THE 2020's: I stored 10,000 identical copies of what you were doing in 500 different global datacentres at a carbon footprint equivalent to leaving a semi-trailer idling 24/7 and also sent a copy to the FBI just to be safe. Let me know which one you want and I'll do my best to figure it out. By the way here are 10 things which are similar to what you were doing and 9 of them are ads. Do you like this?

Is Microsoft trying to take the Internet back to Fidonet or straight back to CompuServe? 🙃
