"He walked up to Helen and asked, 'What are you doing?'"

"He strode up to Helen and asked, 'What are you doing?'"

"He sidled up to Helen and asked, 'What are you doing?'"

"He tromped up to Helen and asked, 'What are you doing?'"

Each of those sentences conveys as slightly different action. You can almost imagine the person's face has a different expression in each version.

Yes, I hate it when amateurs just search/replace by thesaurus. But I think different words have different connotations, even if they mean roughly the same thing. Writing would be poorer if we only ever used "walk".

The Hawaiian language has a concept called Kaona, which is essentially embedding deeper meanings in contextual word choices. It can go way beyond the literal meaning of the words, and tie into bigger concepts of culture, lineage, and places. It's super cool hearing about it from native speakers.

We don't really do it intentionally in English, at least to the same degree. But there's still a lot of information coded in our word and grammar choices.

alexose commented on Analysis finds anytime electricity from solar available as battery costs plummet   pv-magazine-usa.com/2025/... · Posted by u/Matrixik

The scaling up of battery manufacturing for EVs and now solar storage has lead to prices I would have never imagined I'd see in my lifetime. It's one of the success stories that, having lived through it, has been a real joy.

I know that folks might have been able to point to a graph years ago and said we'd be here eventually, but I had my doubts given the scale required and hacking through all the lobbying efforts we saw against solar/battery. Alas, we made it here!

In addition to coming so far down in price, it's amazing to me how good the technology has gotten. Batteries that can easily discharge 5C in cold weather, cycle 10000 times, survive harsh conditions with zero maintenance. Panels that last for decades.

Which is why it makes me especially angry that the current US government is throwing away this gift in order to appease a bunch of aging leaders of petro-states. Literally poisoning the world for a 10-15 year giveaway to the richest of the rich.

I take some solace knowing that fossil fuels are now a dead end. And even though certain people are trying to keep the industry going, that end is sooner than ever.

alexose commented on Crews claim Boring Company failed to pay workers and snubbed OSHA concerns   nashvillebanner.com/2025/... · Posted by u/breve

I maintain the belief that Boring Company's purpose, first and foremost, is to confuse and derail (pun intended) local efforts to build real transit.

Anything they do happen to build is incidental to that goal, and as such it's unsurprising that actual construction would be a shitshow.

The original stated goal was to 10x the speed of existing tunnel boring machines by bringing up the cutting head RPMs, automating liner installation, and speeding up spoil removal with electric sleds. Which would seem like a good bet, except that there are a million other bottlenecks to the process. On top of that, it doesn't seem like they even solved their core problems.

It would be cool if they'd post a postmortem or something, but I get the impression that reporting bad news is a good way to get fired in an Elon-run organization.

Space is so ridiculously big that I don't think it will ever happen.

Back of the envelope math - 4.2 light years to the nearest star that's not the sun, current vehicles traveling about 10x the speed of voyager (e.g. 1 light day in 5 years). If something was launched today it would get to the nearest star system in about 7,660 years (assuming that star system also a radius of 1 light day).

100x faster than current (1,000km/s) would still take 76 years.

Definitely not before 2100 and almost certainly so long after that we will seem like a primitive civilization compared to those that do it.

Just spitballing, but maybe it would be possible with relatively modest advances in ion thrusters, and one (admittedly less-than-modest) breakthrough with fusion.

It's maybe too speculative to even matter, but I don't think it's _crazy_ to imagine a handful of AI-fueled advances in materials discovery during the next decade or two. Possibly enough to unlock laser fusion, or something that could be crammed onto a spacecraft.

ishtanbul · 25 days ago
Here is my proposal for AI in schools: raise the bar dramatically. Rather than trying to prevent kids from using AI, just raise the expectations of what they should accomplish with it. They should be setting really lofty goals rather than just doing the same work with less effort.
alexose · 25 days ago
Absolutely. I'd love to see the same effect happen in the software industry. Keep the volume of output the same, but increase the quality.

Just had a fantastic experience applying agentic coding to CAD. I needed to add some threads to a few blanks in a 3d print. I used computational geometry to give the agent a way to "feel" around the model. I had it convolve a sphere of the radius of the connector across the entire model. It was able to use this technique to find the precise positions of the existing ports and then add threads to them. It took a few tries to get right, but if I had the technique in mind before it would be very quick. The lesson for me is that the models need to have a way to feel. In the end, the implementation of the 3d model had to be written in code, where it's auditable. Perhaps if the agent were able to see images directly and perfectly, I never would have made this discovery.

Generative CAD has incredible potential. I've had some decent results with OpenSCAD, but it's clear that current models don't have much "common sense" when it comes to how shapes connect.

If code-based CAD tools were more common, and we had a bigger corpus to pull from, these tools would probably be pretty usable. Without this, however, it seems like we'll need to train against simulations of the physical world.

A tragedy. Killing this and Revolution Wind are some of the most consequential acts of the Trump administration. We are now unable to do large scale grid-connected energy projects and won't be able to take advantage of the incredible advances in efficiency renewables provide. With data centers causing the first increase in per-capita energy usage in decades there's a good chance we have an actual power crisis and the administration's other priorities like reshoring manufacturing become impossible.
alexose · 2 months ago
Yep. It has massive ripple effects for manufacturing, especially as more industry transitions away from fossils for heat generation. Energy accounts for around 40% of the opex for steel manufacturing, for instance. Zero chance we build more steel mills if the cost of electricity continues to skyrocket.

The Chinese have the right approach: Bringing the cost-per-watt down using massive deployments of renewables and ultra high voltage transmission. We were already in the backseat, and now we're not even in the same car.

Okay, how much pollution was caused creating it? How does that compare to the expected lifecycle of other power plants?

Shutting down H1Bs is extremely stupid because >50% of our unicorn founders are first generation immigrants that started out on the H1B. They are the greatest creators of jobs in the entire economy. Shutting down the H1B is a dark horse for the end of American success.

It's absolutely insane. At some point you have to wonder if this is deliberate sabotage.
