Alarming number of people now vape, says WHO More than 100 million people, including at least 15 million children, use e-cigarettes, fuelling a new wave of nicotine addiction, say experts.

100Mn + people with 15Mn vape all around the world. Children are 9 times more likely to vape than adults. Alarming!

Also, the more technology develops - the expectations of outcomes from that technology increases too. Steve Jobs once talked about how on average 3h to render a frame for a Toy Story scene in mid 90s despite computers getting 100x faster because the frames also got 100x complex.

I think #iOS26 is some larger play by Apple in the future. Otherwise, it looks like a cartoonish design of iOS system. The latch on/off buttons to the transparency - not sure what the goal here is or is it just β€œWe got bored, let’s YOLO”. It reminds me of iOS 5 where everything broke.

Sometimes, things just come together. Like life or Claude Code fixing a 1-line bug after working on it for 1.5h.

I’m not sure if there’s any point with Codex if you can exhaust your weekly quota in 20% of sessions compared with Claude.

Productivity != number of hours worked. Besides, a very high deductible from gross income lowers the incentive to work . Moreso, after having kids. Taxes and deductions make more work less appealing.

Claude Code tries to make the tests easier to pass them but it’s obvious it learned that behavior from humans. I was reminded of that today.

It’s always befuddled when individual tests run but the entire suite doesn’t because of inter-teat dependencies.

6-0, 6-0 in a #Wimbledon final is something I don’t think I’d ever see. I don’t think I have ever felt bad for a finalist as I am for Anisimova. Swiatek finally has trophy she so dearly wanted.

The area of Paris is 5.5 sq km in size. Enforcement remains very low there too. The size isn’t the dame. Meanwhile, a monthly public transport ticket cost 101€ per month with subscription and 89€ per month in Paris without subscription. Expect ticket prices to rise further next year.

2nd order effects are rarely understood in Germany. I think one can write an entire book on the amount of times you will see this happen.

Sure but that would make Bluesky cease to exist. The dissident voices are silenced by governments. It’s an unreasonable expectation for Bluesky to fulfil a gap which no other government or international organisation has. They are still different given the legal limitations (for now).

Entities have to function within the law of the countries they operate in. Any other expectation is utopian and largely a futile exercise.

You work with the world or the world works without you. The laws of physics at a macro level have their defined boundaries. You have the opportunity to understand them and factor them in your decision making. This applied to everything - society, trade. Bet against them at your own peril.

Trapping misbehaving bots in an AI Labyrinth How Cloudflare uses generative AI to slow down, confuse, and waste the resources of AI Crawlers and other bots that don’t respect β€œno crawl” directives.

Here’s more on how it works. I’m happy to see that you benefit from the work we did
