So some chip designers used ChatGPT as a rubber duck. Useful, but it didn't become the designer.

Spotify is constantly finding new ways to irritate me when opening their app. I just want to listen to music, but their app wants me to look at modal popups for promos I don't care about, and recommends me music genres that neither I n

Really good information. I have only used naive spinlocks on hacky ducttape for embedded RTOSes. And most of the time those will provide better mutex or semaphore functions you should be using instead of the spinwait. Interesting that the e

It's not the landlord they were worried about. They expected visits from the housing authority who sometimes check up on the tenants. The biggest one is when taking section 8 is you aren't allowed to have guests staying for more t

Thanks for that article, it confirms what I'd long suspected. The bit about traffic cameras is a good one, and the very same problem of trying to judge health supplements efficacy without RCTs.

Interesting why it decided to draw a bounding box around the dog's head, maybe because its training images are mostly dog portraits

Years ago, my dad owned and rented out some Section 8 houses in the hood. Tenants were single moms on welfare with usually 3 to 4 young kids. Many times he'd knock on the front door after a call to fix the toilet or some such repair, b

A common number for improvements in outcome by placebo is typically 20%. Significant, but not a game changer.

I think people in western countries have been a victim of our own successes, where we enjoy such a prosperous (relative to most of history) life that we now unwittingly afford the luxury of forgetting how raw human behavior actually works.

It's all relative to its contemporary FOSS applications, and it may well be beautiful compared to some of those :)

Excellent analysis and fix of the problem! I've found Chinese clones are always subtly different than the parts they supposedly replace.

Probably an old Lecroy! With the floppy drive next to the thermal printer.

I also had one. 1tb+octane cache. It actually was a net decrease in performance! The reason is that first writes would saturate the cache SSD. Then the octane driver software must manually flush the cache to the main SSD. What happened was

I suspect they wanted to change off Basecamp anyway maybe for legitimate technical reasons, but couldn't resist trying to score some brownie points with their sophisticate librarian cohorts.

A typical high-end 18650 li-ion cell from 1996 was 1400mAh. A typical high-end 18650 from 2023 is about 3200mAh. In other words, it took 27 years for battery tech to achieve a bit over a doubling in energy capacity. Even if we wait another

Except for the rare cases where a chip can be decapped, turned into a netlist and painstakingly translated 1:1 into logic primitives (which itself is usually impossible without some fudging), all re-implementations are exactly that. You can

It does have DMA but this only speeds up data transfer. You are probably thinking of PCI bus mastering, where the PCI slave temporarily takes control of the bus to read and write main system memory. This still exists in PCIe and thunderbolt

Seems like an oversight that the extra stuff the 68302 added wouldn't have been a DMA block copy or something.

Back in 2007 when I did my first board, the only option I could afford was a US fab that had a "33 each" special. You got a 2layer board with HASL finish and had to order 3 of them. So it cost $100. If you were academic they'

Restrictions or constraints being creativity. That's the whole fun of it. No fun in pressing F to win.

Win2k was peak windows. Though, it did need a lot more RAM than 98 did - it was happy only at 128mb, and 256mb was optimal. Meanwhile, 98 could run most things all day at 64meg. 98's swap and caching agent was definitely not as good as

Maybe for day to day stuff. But sometimes, maybe even once per year, that one road trip where multiple charging stops at hokey non Tesla stations is enough to prevent a lot of people from jumping. Lots of people want the possibility of do

Been donating to Ducks Unlimited here in the US for years. Their angle is to protect the hunting pastime, but to that end involves getting involved with many states' local issues to keep the wetlands protected. Just a drop in the bucke

Indeed, a good RTOS from 10-20 years ago works just as good now as it did back then. The only things that change are dev environments and the driver support.

The only weak point of the x230 was the stock TN display was absolutely awful. I swapped it for an IPS. One day I dropped it about a foot onto a carpet floor, and the metal chassis accordioned and bent in the corner. Was not impressed by th

Maxim parts were and remain bulletproof, with prices to match . I think eeprom longevity is intentionally understated due to practicalities of testing and possibly wide variations in lifetime beyond the spec. And then you have Chinese domes

My gut feel was also cracked MLCC ceramics from thermal expansion or shock. I've seen some 1206s shear right off a pcb from merely mechanical shock to the PCB, not the cap directly. When I use them I try to orient them parallel with an
