Had a great time last week delivering one of the A-level residential days for the NCCE @wearecomputing.bsky.social at the STEM Centre in York. I had the joy of explaining the origin of the phrase "2's complement", and doing lots of floating point binary exercises.

If I set up a projector aimed at Big Ben, and projected political posts, current affairs, recipes, opinions, child sex abuse material and cat pics on rotation, how long before it gets shut down? Asking for a nation.

The X Effect: How Elon Musk is boosting the British right For nine months, Sky News' Data and Forensics team has been investigating whether X's algorithm amplifies right-wing and extreme content. It does.

They get almost no reach there any more. Musk saw to that.

In the spirit of brotherly love, could I gently enquire why the almighty **** are government departments, government ministers and Labour MPs *STILL* using X?

When I was a kid it was mimicking The Fonz (thumbs akimbo, "Heyyyyy"), or Yoda impressions. Yes I'm that old. Yes I still do these.

Compute isn't the problem, it's complexity. The recent Cloudflare outage shows how hard it can be to diagnose a fault in millions of lines of code scattered over thousands of instances.

I think you're holding up "1066" as an example of a "fact" which is irrelevant, but in this discussion you have alluded to many facts which are indeed relevant. You are mocking a common parody of "useless facts" (dates of battles) while admitting that facts in general are valuable knowledge.

Wow this has taken off. The screenshot was sent to me by a friend, not sure how to credit the original author. I don't have a soundcloud 😁, so instead please thank me by checking in on someone vulnerable today, because the billionaires won't. Thank you.
