Microsoft is addressing a Windows 11 bug that caused a folder to take up several gigabytes of storage space. As spotted earlier by Windows Latest, Microsoft included the patch in its optional June 2026 update (KB5095093), which "improves disk space usage for the CapabilityAccessManager.db-wal file." The CapabilityAccessManager.db-wal file is installed on Windows 11 PCs by […]

Show HN: Yamanote.fun – A complete soundscape for Tokyo's Yamanote line

After visiting Japan for the first time a decade ago I became completely enamoured with Tokyo's Yamanote Line railway loop. Particularly the sonic experience of it. Like so many others I fell in love with the charming departure melodies and enjoyed discovering experiences like Yamanot.es ( https://news.ycombinator.com/item?id=45045307 ) here on Hacker News when I returned home. But it wasn't until my second trip to Tokyo that I truly appreciated how much the door chimes, on-board announcements a

Tell HN: Who wants to be hired" posts outpace "Who's hiring" 2 to 1

Lately I've noticed that "Who wants to be hired" posts are getting more comments than the "Who's hiring" ones. I pulled the data using HN API and confirmed this "reversal".

I'm old, I'm from the times where demand for software devs greatly outpaced supply, but maybe we're seeing a reversal of it? I don't want to draw any conclusions yet,

Show HN: Frugon – Find which LLM calls a cheaper model could handle (local, MIT)

I started leaning in on AI heavily this year, as I wanted to get more done autonomously, but then my token usage climbed dramatically to the point where my weekly quota would run out before the end of the week, sometimes a couple of days into the week. I realised I had to do something about it else I'd have to double my spend. So I decided to start tracking my cost per task type. This revealed that a lot of my spend went to searches/scans or simple things like scouting tasks. I then decided to t
