🆕 blog! “Get Chartered!”

Computing is a comparatively young industry. We don't have hundreds of years of history, or secret societies jealously guarding our knowledge, or much love for hierarchy. This makes it difficult to progress in a world which values strict demarcations between people. There's an obvious and well documented path from Army Private to Sergeant. If you're […]

Eurostar say leisure travel is back to 100% of pre-pandemic levels & business travel 80-85%. But due to Brexit they can only provide 70% of pre-pandemic capacity. They've plans to resolve this including trialling online check-in, I've added a summary at https://www.seat61.com/news.htm

I appreciate that people with good/unlimited internet connections don't often care about the size of websites. But it does matter for both the environment and those on limited data plans e.g. my phone has 250MB/month and then have to pay 1p/MB above that.

I monitor UK local authority homepage sizes and, for each, list their biggest resources and give tips on what they could do https://open-innovations.github.io/council-website-emissions/ Usually it is massive images that they could easily optimise.

⚠️ Update: Internet connectivity has fallen further in southern #Turkey and particularly in #Osmaniye as authorities implement emergency power shutdowns to support the rescue effort; levels collapsed in the region earlier today after a series of deadly earthquakes ⚡📉

Did some deeper digging into the Teletex protocol stack. So we have X.21 physical interface at synchronous 2400 bps with HDLC/X.75SLP as link layer and then T.62 as session and document layer. Interestingly, T.62 was also reused for G4 (ISDN) fax. Rather complex state machines, nothing you can implement in an afternoon. https://de.m.wikipedia.org/wiki/Teletex https://osmocom.org/projects/retronetworking/wiki/Teletex

What's inside the famous 8086 processor from 1978? I opened up a chip, took microscope photos, and I'm reverse-engineering it. One of the 8086's instructions is HLT, which halts the processohttps://pbs.twimg.com/media/FnalrlNXEBoU1I_?format=jpg&name=4096x4096r. Seems simple, but there's a lot of circuitry to make the halt instruction work... 🧵

#Accessibility is cool.
I had wondered about the change, but never checked.
Excellent work by @FinancialTimes

Sunak apologised for taking off a seatbelt for 30 seconds. Zahawi won’t apologise for failing to pay £3.7m of tax, lying about it, threatening to sue people who write about it, and then secretly admitting it all to HMRC and paying up behind our backs https://taxpolicy.org.uk/zahawi_story
