ChatGPT’s signature writing style is everywhere now, and I hate it. It reminds me of when we tried mixing all the beverages at the soda fountain in middle school. We didn’t actually create the perfect drink, we just made a cloying monstrosity that lost everything good about its constituent parts.

Really enjoyed this latest @volts.wtf episode with @kingsmillbond.bsky.social, especially the analogy of energy storage technology being like granaries:
"Imagine global agriculture if you couldn’t store grain, you just had to eat it out of the fields." (1/2)

Kingsmill Bond explains why the global march of "electrotech" has moved beyond the reach of US political interference.

Started a fun #gamedev side project: I'm making a web-based version of #sokoban with #svelte, #typescript and #css. Got basic graphics, animations and controls working and just finished the improved version of a solver. It currently solves 90% of the 154 Microban levels in under 10 secs. #wip

This can be hard to spot, because the empty arrays will look the same (i.e. `[ [], [] ]` will look like `[ [], [] ]`).

@edzitron.com You should see this... It seems like all those $$$ spent on Cursor and other "vibe coding" tools don't actually make developers more productive (but make them think they are). The perfect punchline to the enshittification story 😂
We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.
The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

Oh, wow. I had a hunch #LLMs don't actually make devs more productive, but this is ... pretty damning.
And (as pointed out by others) it doesn't even account for the time required to fix all the vibe-coded bugs later on.

I wrote a few words on #battery #energy storage systems and the role of sodium-ion batteries. They are an interesting hedge against future lithium shortages, but the big Chinese players will continue to dominate the global market.

Sodium-Ion Batteries Won’t Free Us From Chinese Market Dominance — KlaasNotFound
