Openscad models are a bit like complex regexps, write only artifacts that do the job at the time but are regarded with trepidation afterwards.

Fusion 360 and my golf sim software are the only two reasons I have windows dual boot.
A little bit like a country's leader calling for the death penalty for a decorated pilot and astronaut who reminded service members of their duty to reject unlawful orders.
Re:FreeCAD is an open-source parametric 3D modeler on Friday February 20, 2026 @01:49AM (#47084588)
I feel CAD is one area where open source does not shine. The problem space is too complex, and the UIs demand continuous, thoughtful development driven from customer demands rather than developers scratching their own itches.

Not least there are free (as in beer) solutions available, like fusion 360, that are enormously capable.

Theres certainly a place for open source, and openscad would be a great tool to reach for for procedurally generated models. But in all honesty, Freecad doesn't compare well to the professional tools in this space - not in the way that say, gimp does to its commercial competitors.

I've just now done exactly this. Model something (not an apple) not because I want to print it, but because I need to import it into CAD to check clearances etc. around it. I can abolsutely imagine modelling different sized apples if I was building an apple sorting machine.
Agree! I've been computering for 50 years and for me the significant milestones have been:

- rdbms

- PC

- Internet and email

- SaaS

- Mobile

- social media

- LLMs

I doubt that LLMs will be anything like as significant to our futures as social media though. And not in an entirely good way.

The example - the cable not extending far enough from the post to make a connection - was explained in the article as something he failed to specify properly. Not a failure of the manufacturing partner.

For this not to be a problem a worker would have to notice it and put two and two together, then investigate further and then persuade their supervisor to raise it with the customer and get a change made to the spec.

While enjoying your faith in the rigour and attention to detail of the US assembly line worker, I think this example tells exactly the story the article says it does - that you have to specify everything.

Is that counterintuitive? If I had a model trained on 10 different programming languages, including my target language, I would expect it to do better than a model trained only on my target language, simply because it has access to so much more code/algorithms/examples then my language alone.

i.e. there is a lot of commonality between programming languages just as there is between human languages, so training on one language would be beneficial to competency in other languages.

Thanks for the link, that is very impressive.
Re:"Anyone else out there vibe circuit-building?" on Monday January 19, 2026 @02:02PM (#46683020)
If I understand what you are doing this sounds like a great idea.

For example a part like the ADS7953 ADC comes with layout recommendations, including the design of the ground plane underneath the chip and the placement of the decoupling caps. A more extreme example would be an esp32 and all of it's supporting parts, including the keepout area on the PCB for wifi transmission.

I really want to assemble circuits out of higher level primitives like that, drag and drop a chip and all of its supporting parts, including their layout and power connections.

I find both chatgpt and Gemini to be very good at writing c++ for Arduino/esp32. Certainly better than me unassisted. Compile errors are very rare, and usually they are just missing declarations. Right now I would say chatgpt is ahead for daily driver use but sometimes Gemini can instantly unlock things that chatgpt is stuck on.
Re:Drones that recharge directly on transmission lines on Saturday January 10, 2026 @05:12PM (#46570432)
Yes, feels like perching via some insulated "feet" and only using energy for stabilisation (as opposed to flight) would allow the drone to get very cloe (and suck much more power) from the line.
You really created an account to post this?
Removing CO2 from the air is a pipe dream for several obvious reasons.

Firstly, it will always be more difficult and energy-intensive to extract CO2 than to just stop putting it into the atmosphere in the first place. Yet the world is nowhere near agreeing any meaningful framework on reducing emissions, and the party in power in the largest democracy in the world is in denial that a problem even exists.

But mainly, if there was an effective means of CO2 removal, who will be in charge of the dials, and who will set the targets?

Atmospheric CO2 is now 50% higher than when I was born. Will we go back to the levels as at the 60s, or perhaps the beginning of the industrial revolution? Obviously that is unfavorable to the frozen regions that are now thawing - like Russia (and Greenland), who benefit from climate change.

As a non-American, but one who worked in US companies for decades, I feel Americans are influenced by economic gigantism.

The American experience is of triumphing with audacious, go big or go home schemes that others wouldn't or couldn't attempt.

To cherry pick one example, during WWII the US created airstrips on tiny pacific islands to fight the Japanese. Few people imagined it was possible to freight in the bulldozers, machines and materials to accomplish this, and it was game changing.

And of course we have the Manhattan project. Railroads. Gigantic IT companies like Oracle, IBM, Apple and more lately Google.

These successes fed into American exceptionalism.

This has its pros and cons.

In a world on the cusp of incredible discoveries, it let audacious American megacorps capture the high ground.

But explosive capitalist success has costs and masks underlying issues. Many people have had the experience of starting work at US Megacorp and being astonished at the waste, ineptitude and back stabbing that happens - yet somehow the corporate continues to thrive and throw off mountains of money.

The experience of that easy money breeds an unhealthy version of American exceptionalism where people start to believe they will and should succeed - just because American.

Things are different elsewhere in the world.

Up and comers make do with what they have and struggle upwards while the USA cruises.

Just one example are the thriving Chinese fabbing companies like JLCPCB. Every tech product contains a PCB. It's pretty obvious now that PCB manufacture is an absolute core competency in tech going forward.

Any two man upstart tech company can use JLCPCB's free online tools to design a PCB, then click to have the factory fabricate the board, solder on all the components and connectors, and have it in the customer's hands a few days later. True on demand manufacturing.

What would have cost thousands of dollars, taken months and required a team of experts a few years ago now takes days and costs a few bucks.

The US is nowhere in this relatively new but critical industry. The only US competitors are stuck in a local minimum where they get assured business at generous prices from security-sensitive govt agencies who can't outsource to China, but they can't remotely compete on price with their Chinese competitors on price or even quality and timeliness.

A keyfob is more analogous though - i.e. a computing device used to control a vehicle.

A golf launch monitor that lets you practice and play sim golf inside. Doesn't require an actual golf ball and lets you use your own clubs.

Using an esp32, high speed ADC and 4 bass guitar pickups to detect and reverse engineer the club's path and face angle as it swings past the pickups.

Re:Freeing a Xiaomi Humidifier from the Cloud on Saturday December 13, 2025 @12:42PM (#46256338)
My brother's house in Perth, Australia has an antique air conditioning system in the roof space that works in exactly this principle. 4 blankets that wick up water and have air drawn through them and into the house by a fan. It's in disuse now but I understand they were common and quite effective in the day.
Re:Are We over the "Jaws Effect?" on Wednesday December 10, 2025 @02:10AM (#46214975)
Jaws is the only movie (within reason I guess) that I don't let my 13 year old watch.

We live by the sea with one of the world's best marine reserves right off shore. There are plenty of fish including sharks living right off the beach and you need nothing more than a mask and snorkel to get right in amongst them.

When I watched Jaws as a kid when it first came out, it scared me shitless and I still carry some of that trauma whenever I am snorkeling over a deep canyon where the blue just goes on forever and you can't see the bottom.

I just don't want my child to miss out on that because of the ability of Hollywood to scare us.

Do you have kids?

It's much easier to say to a child "you can't have a social media account, it's the law because experts have determined it's not healthy at your age" than "your mother and I think that social media is bad for you".

> So you want to make it legally viable for religious parents to sue social spaces that allow for their children to question the religion of their parents?

Why not. In a court of law, and facts, such lawsuits would only serve to highlight that religion is not a real thing. That would be a good thing for the world.

Re:IBM to Acquire Confluent on Tuesday December 09, 2025 @02:42AM (#46202309)
That's an interesting and enlightening way to look at it.

For me it was the death of IBM's preeminence in IT. When I started there a job at IBM was prestigious,a job for life. More than once I was told that we had a lengthy backlog of inventions and technological wonders that could be wheeled out of the plant if competitors ever nipped too closely at IBM's heels.

At that time IBM had never made a single person redundant - anywhere in the world. The company had an incredible sophisticated internal HR platform that did elaborate succession planning and considered training and promotion as major workforce factors - there was little need to think much about recruitment because jobs for life. IBM could win any deal, maybe needing only to discount a little if things were very competitive.

It's impossible to imagine now what a lofty position the company held. It's not unfair to say that, if not dead, the IBM of old is no longer with us.

Re:Hunting for North Korean Fiber Optic Cables on Tuesday December 09, 2025 @02:32AM (#46202249)
The subsequent Vietnam war reinforced this even more.

The only path that America had to win in Vietnam was to destroy it, including the population they were allegedly there to protect. Hence they lost.

Re:IBM to Acquire Confluent on Monday December 08, 2025 @11:08PM (#46201128)
I joined IBM over 40 years ago, like my pappy before me.

My main takeaway from IBM's longevity is just how astonishingly long big companys' death rattles can be, not how great IBM are at running software businesses.

It's just the same dynamic as old servers. They still work fine but power costs make them uneconomical compared to latest tech.
