Can’t believe my luck of cosmic proportions. I bought a ’83 Yamaha SG that came with just one of the original pickups. I found a NOS spare part pickup from Yahoo Japan Auctions and turns out it’s from the same year, same month as the other one!! #guitarsky #guitar #yamahasg

The general brazenness of how LLMs were conceived seems to have influenced the use of LLMs at work. When organizations are pushing use of "AI" heavily, it can lead to reckless sourcing of data. This blurs access control and makes PII usage harder to audit.

Some PCs like mine require manual steps to qualify for the Windows 11 upgrade: - convert MBR to GPT - disable CSM (compatibility support module) - turn on UEFI Technical, yes. Difficult, no. I would gladly help a relative or a neighbor if they asked with this.

In the next version of Liikennematto, it's easier to keep lots when making changes to connected roads. I've added 19 new lot entry tiles to accommodate all possible configurations of nearby roads. You can now, for example, create a cute cul-de-sac! #screenshotsaturday #gamedev

✨ Big O ✨ Let me take you on a visual introduction to what big O notation is in my new blog post: samwho.dev/big-o. With big O notation you can better understand how algorithms will perform in practice, finding orders of magnitude improvements often with very simple changes to your code.

Matias Klemola @matiasklemola.com · 23/08/2025
I’ll add that O(nm) is used for 2D array based functions (e.g. inner loop). Maybe this is something that warrants a mention, like a footnote (to avoid complicating the meat of the article)?
010
Matias Klemola @matiasklemola.com · 23/08/2025
Right. I’ve seen examples with multiple components, signalling that an algorithm has multiple expensive operations to it (for example, in a gamedev book). In a case of two linear components, there is no clear winner, I guess?

Matias Klemola @matiasklemola.com · 23/08/2025
Great post, as expected! 💯 I wonder about the buildList example, though. The time complexity analysis of the function seems to omit the .join() operation, which makes the big O value either O(n^2+n) or O(2n), right?

I rather have an ever-evolving style with inspired results than rehashing of old ideas. The track would sound like Tame Impala even if you removed the vocals. There’s something in Kevin Parker’s production that transcends genres.

This is a welcome change. I'm not against (LLM) AI for coding but prefer to maintain command of the coding workflow. Note that this change does not change the balance of Zed development, so AI still takes away resources from development of other features (same as VS Code). zed.dev/blog/disable...
