BBC international editor Jeremy Bowen, speaking to the FT, on impartiality www.ft.com/content/b139...
Later, he tells a story about impartiality. In Sarajevo in 1992, he saw the shelling of two children’s funerals. “I wanted to do a piece to camera saying, this is the most monstrous war crime you can imagine. I wanted to rant.” Then his BBC instincts kicked in. “I just described what happened.” Nineteen years later, the piece was used as evidence against Bosnian Serb leaders Radovan Karadžić and Ratko Mladić. “I remember thinking, if I’d got on my soapbox, would they be admitting it in the war crimes tribunal? I don’t think so.

It’s Alex’s first day. You want to help them make a big impact fast. You let them use your computer, email address & app logins. They’re so quick you can’t even see all the steps they’re taking. What could possibly go wrong? Why can’t we onboard LLMs the way we would really onboard an employee?

Great short post from @mheap.dev: michaelheap.com/visibility-i... It takes practice to deliver the right level of abstraction--too many details are not great. But surprises are so so bad. Even if Alice delivers a month later than Bob, people understand why and are more likely to accept it.

The Web Runs On Tolerance
If you've ever tried to write a computer program, you'll know the dread of a syntax error. An errant space and your code won't compile. Miss a semi-colon and the world collapses. Don't close your brackets and watch how the computer recoils in distress. The modern web isn't like that. You can make your HTML as malformed as you like and the web-browser will do its best to display the page for…

At the risk of starting the flame war to end all flame wars... Modern LLMs (GPT-5.1, Claude 4.5, Gemini 3) produce excellent code and can be a significant productivity boost to software engineers who take the time to learn how to effectively apply them - especially if used with coding agent tools

I've been given a packing list. On Thursday morning at 9am I fly from Gatwick. I'll return to Gatwick at 6pm on Monday evening. For the ~100 hours between the flights I'll be offline and unreachable - I don't know what I'll be doing. I'm trusting that time to a good friend and a mountain guide.
