Awesome project.

I consider myself someone with a good sense of direction in big buildings, malls, hospitals, etc., maybe a side effect to playing video games and such, but it's rare for me to get lost in big, complex structures.

But man, Shinjuku humbled me badly. That thing is a Metroidvania level IRL. If you ever go there, please don't buy a ticket with only 5 minutes to get to the right platform. Give yourself at least 15 minutes or more.

It's an awesome place, but even with signs in English, it can be easy to get lost.

Im surprised by how bad LLMs are with SVGs but somehow are oke-ish with CAD and other weird files.

This. It may be a niche. But music that works with volume as part of the composition can be amazing.

But most music today has heavy compressors in the pipeline that kills dynamic range in favor of allowing you to hear almost even whispers, even in traffic or a city with ear pods.

But if you're from the first group, as you said it's more noticable the benefits of having better codecs and bit depth vs heavily compressed top billboard songs where even listening the master track from the studio, falls into diminishing returns.

Agree. It's clear since COVID that Pi it's barely a company for makers or DIYers anymore, but it's a supply company for small to medium industries to integrate cheap PCs in their manufacturing process and they are good at that role.

For reference this is a big price hike:

Plus went from x10 usage to only x2 vs the free tier. Pro from x33 to x4 Ultra from x166 to x80

I think it’s too little for this day and age as well, but in Apple’s defense, their RAM compression on ARM works amazingly well and performs similarly to 12GB on Windows.

With that said, I hate that you can’t upgrade the RAM or storage.

I hope that at least one side effect of this is that developers will have a business case for performance improvement dev time, as those machines will become a juicy target, similar to video game consoles that may not have the best specs but are consistent and have a large number of units in the market.

What I think was a wasted opportunity was not bringing the xserve back, being one of the few e2e solutions out there at scale.

AI being a bubble it's not mutually exclusive of being a real and useful technology and the existence of non-snake oil companies.

Cisco was a bubble in the dot com crash, despite being a company that provide real value and profit, just not at the level of the crazy expectations from the time.

Totally. I would add that code that "works" it's easy to do. Code that it's efficient, easy to maintain and safe... That it's another story.

But the sad truth is that most software can be or it's done with shitty code that "kinda works" as long as the CPU it's fast enough.

Yeah a ramdisk would probably work wonders. It's a shame Intel optane didn't became a standard, those type of workflows would be amazing for it.

I bet we'll the the SUV mania in the future as something crazy, like smoking in a plane or using lead for gasoline. Irrational large size cars that people get because everyone it's afraid of another SUV hitting them in a sedan. The tragedy of the commons.

I think this is the way, automated testing for all patches, small changes, and manual testing for big releases.

javchz — Mon, 13 Oct 2025 23:30:42 +0000

As many flaws as the npm/yarn/pnpm ecosystem has, its interoperability is waaaay better than the whole juggling act between pip, ven, poetry, Anaconda, Miniforge, and uv across projects.

UV it's a step in the right direction, but legacy projects without Dockerfile can be tricky to start.

Specially in the high end, you want oled or high refresh rates? You have to buy a "smart tv" that requieres internet to setup, even if you plan use it only with an HDMI device.

New comment by javchz in "Gene-edited pancreatic cells transplanted into a patient with type 1 diabetes"

Yes, but even lifestyle changes (like a diet low in glycemic load and building muscle) can help reduce many of the harmful effects of type 2 diabetes, even sending it into remission for some people in early stages.

Type 1 is a different story. It’s the lack of natural insulin production (due to a damaged pancreas, autoimmune or other causes), basically the opposite problem to type 2, and no amount of lifestyle changes will replace of need of insulin doses.
