what does this sentence mean?
> Apple is simply exporting to CUDA now.
My takeaway was definitely not that all of Apple is using only one framework.

This is really great.
Bummed I didn't see it before. I made a really precise timebase and a fairly precise interval counter a decade ago using pretty different techniques (ECL and staggered delay lines and a lot of calibration). It would have been nice to know more about these techniques.
I've been wondering if it's possible to recreate this with today's technology. The HP implementation uses a custom ASIC with very fast transistors, so it's not obvious.

If you want to make your own interval counter today, the to-go-to method is to use a TDC7200 chip. If that's not good enough, you can also look at the schematics of an SRS SR620 time interval counter. It has a similar 25ps precision and uses an ADC to interpolate between samples of a 90 MHz clock. These kind of ADCs weren't available in 1978.

I love the old HP app note linked: https://ilrs.gsfc.nasa.gov/docs/time_interval_measurements.p...
The fact that we have this discussed in the open, in such a transparent way, is great. HP was confident they could maintain their lead while talking about methodology and design. The marketing value of open communication to showcase their leadership (and to enable engineers using their products to learn to do similar things outside of the test space) was evident.
If you haven't already, you should also check out the HP Journal edition that was dedicated to this counter: http://www.hparchive.com/Journals/Low-Resolution/HPJ-1978-08....

My biggest gripe is with iPhone photos today is the way small details get mangled beyond recognition. Small text looks like it was sent through a hallucinating LLM (which it probably was!)

In February, the RP2040 was officially declared 200 MHz capable. All that’s left now is for the RP2350 to be declared the same. Right now it’s only 150 MHz.

I exhibited there, and I had a lot of fun. My friends co-hosting the noisebridge booth got a lot of folks to find a makerspace near them. Several general attendees told us that the very first time they had soldered was at Open Sauce, when putting together their badges. The event has positive impact, and I'm hoping it sticks around.
I would like to exhibit some of my nerd stuff, but the rules say that your booth most always be manned by someone. How then would I be able to visit other booths?

Propagation delay is a thing.
Edit: at some point the memory controller gets a chunk from the lowest level write buffer and needs to compute ECC data before writing everything out to RAM.
Without ECC, that computation time isn't there. The ECC computation is done in parallel in hardware, but it's not free.
The kind of ECC that’s used for register file and memory protection is trivial to compute and completely in the noise in terms of area. It is essentially free.
The reason people say ECC is not free is because it added area for every storage location, not because of the ECC related logic.

Sorry, that conclusion is just silly. I know people in the airline industry (some pilots and a number of flight attendants) and the problem is not that they're forced to conceal mental issues.
The problem is that many people in aviation imagine that they need to conceal their problems. And they point to videos like this one as proof of that, ignoring that the events of discussed in the video are actually proof of the opposite.
Emerson (the suicidal pilot in the video from Alaska Airlines Flight 2509) self-medicated himself using hallucinogenic substances and developed suicidal ideations, because he didn't seek treatment (like therapy) for his mental issues after the death of a friend. If he had sought treatment, he'd still be flying today because he wouldn't have tried to kill several dozen people, and he would have learned to cope with his depression.
What about Xyla Foxlin’s case:

I visited NYC a few weeks ago and was instantly reminded of how much the traffic fucking sucks :) While I was there I actually thought of Waymo and how they'd have to turn up the "aggression" slider up to 11 to get anything done there. I mean, could you imagine the audacity of actually not driving into an intersection when the light is yellow and you know you're going to block the crossing traffic?
It took only a few seconds for a human to answer the support request and she immediately ordered the Waymo to go to a different lane. Very happy with the responsiveness of support, but there's clearly still some situations that Waymo can't deal with.
