Submission + - CERN Open Sources Its KiCad Component Libraries

ewhac writes: CERN, a long-time Open Source pioneer, has made several contributions over the years to KiCad ("KEE-kad"), an Open Source EDA (Electronic Design Automation) package widely used in the hobbyist and professional electronics communities. It's gotten so widely used that users can now submit their KiCad design files directly to several electronics fabricators (rather than the traditional step of converting the layouts to Gerber files). Over the years, CERN have also developed their own symbol and footprint libraries to support their own internal electronic designs. Last week, CERN released those KiCad component libraries, containing over 17,000 symbols, under the CERN Open Hardware License (permissive version).

And then technology just froze. No sensor components got cheaper. Computer vision stopped, as a field. Multimodal AI didnâ(TM)t get invented. Robotic hand technology development stopped. Robotic planning and error recovery did not progress. Time just froze, after McDonalds ended its robotic program.

Welcome to the all-new eStop! We know you have concerns, so let us put them to rest straight away.

The site will not change. We respect the investment you've made in learning and navigating the site. However, if you're feeling curious or adventurous, feel free to check out our [new site design prototype]. (This design will become the default landing page in mid-2027; the old site UI will enter maintenance mode for only the most critical bugs.)

To thwart LLMs and other bots, new default limits on bidding have been imposed. Accounts may only bid on a given item no more frequently than once every 20 minutes. If your circumstances require more frequent bidding, have a look at our [eStop Pro Membership Plan] for only $9.95/month (billed annually; no pro-rated refunds), which will allow unlimited bidding frequency. And for members who want to have more than 20 items on sale simultaneously, take some time to review our [eStop Bulk Vendor Programs], charging only 25% of gross sales, or $3600/year + 20% of gross sales.

And to help with "doomscrolling" for that one specific thing you're looking for, we've also partnered with Anthrop\c and X's Grok to help curate your buying experience, surfacing the items most likely to interest you.

Comment Re:Wildfires in outer space? (Score 1) 77

Got me curioser, so I googled it. One source said what I thought:

https://www.scientificamerican...

"Because gravity is necessary for density differences to arise, neither buoyancy nor convection occur in a zero-gravity environment such as space. Consequently, the combustion products accumulate around the flame, preventing sufficient oxygen from reaching it and sustaining the combustion reaction. Ultimately the flame goes out."

and

"Researchers learned that flames extinguish themselves."

and

"Oxygen could still reach a flame in a gravity-free environment if someone blew the gas into the flame or let it "diffuse" in. It is the diffusion process that spreads the scent of a perfume in a room without air circulation: the perfume slowly mixes with the air to try to achieve a uniform distribution. This process, however, is too slow to sustain a flame."

Other sites don't directly contradict this, but say fires in the ISS are dangerous because smoke doesn't rise and set off smoke detectors on ceilings like in homes, so they install smoke detectors in the ventilation ducts. Also that fires on the ISS can survive on lower levels of oxygen than humans, and thus are much more dangerous if they linger on. That's confusing; if the smoke doesn't rise, then wouldn't it smother the fire like the first site says? But if the ISS has moving air from ventilation ducts, maybe that is what feeds oxygen to the fires.

Thanks for tricking me into not being so lazy :-) But all I learned is that I don't know.

Comment Confounding Factors in Play (Score 1) 66

I’ve only just skimmed the paper, but I think the authors are missing a HUGE confounding variable: the plants of today are not the same plants of yesterday. Commercial food operations have selectively bred crops for traits like colors that consumers prefer, the ability to survive mechanical harvesting and long-distance shipping, drought, disease and insect resistance, reduced time from planting to harvest, and profitability. Neither nutritional value nor flavor is prized.

If you need to see this in action, compare a supermarket tomato with a notoriously fragile Cherokee Purple tomato, or supermarket white rice with Carolina Gold rice. They are damn near incomparable. It wouldn't surprise me one bit if that’s a far bigger impact than a few ppm of CO2 changes.

(I’m not saying that CO2 isn’t a factor; I’m saying that the study design doesn’t support any real conclusions.)

Comment ISDN: It Still Does Nothing (Score 1) 95

(a/k/a Innovation Subscribers Don't Need)

It still amazes me that, as late as the 1990's, and well after 56kbit modems were prolific, ISDN was being offered up by the ILECs as "broadband," at metered rates that made Ma Bell's long distance charges look like spare change.

Happily, it wasn't too long before ISDN was put out of everyone's misery when DSL showed up. And now, finally, after fifty years of pissing about, fiber is finally being pulled to the premises.

If you really need ongoing ISDN support, you can pull the source code from an old Git commit and update it. But I feel quite comfortable in opining: ISDN support will not be missed.

They know exactly what I've bought from them and when, so computing the tariffs I've paid through them is a matter of database queries.

They know how to give the money back to me - they send me a credit based on my executive membership every year, and that would be an acceptable and minimally painful way to refund the tariff windfall. They could give Costco store credit cards to non-executive members.
