I didn't realize they finally added a way to sort of control this behavior. It's under Languages in the YouTube settings. Similarly there is a control for captions languages under Captions/Subtitles.

I think this is likely a process problem. Having been a safety officer for a lab in the past, there are two types of injury reports. One for regular injuries, you have a week to report. Serious injuries need to be reported within 24 hours. These are death and amputation injuries (there might be more, it's been a few years).

Anyway I suspect they missed the deadline because it slipped through the cracks.

NIST maintains several time standards. Gaithersburg MD is still up and I assume Hawaii is as well. Other than potential damage to equipment from loss of power (turbo molecular vacuum pumps and oil diffusion pumps might end up failing in interesting ways if not shut down properly) it will just take some time for the clocks to be recalibrated against the other NIST standards.

I tried to use an LLM for assistance with reversing some embedded code and agree with this. I had built up a pretty decent model of what was going on before starting. It was able to explain what was going on in this one perplexing function quite well but when I'd feed it decent sized blocks of code it would hallucinate like crazy. But I was quite happy with the performance at finding the basic library and ROM functions and annotating them correctly. I think it is all in how you use it.

There is another source, SNI certs showing up on a server or load balancer during the TLS handshake. When the client tries to connect to a server using SNI without indicating the server, some will reply with a default or give a list of valid server names.

While the esp32 is only going to be able to do 2.4 GHz. KrakenSDR can be used in a similar way to do spatial mapping of other frequencies. There was a passive RADAR project for it as well that I think was taken down because of ITAR. https://www.krakenrf.com/

Totally agree. A cheap GPS + Raspberry Pi makes an incredibly capable little NTP server capable of serving 100k clients(after you block the bad actors). The local network is down in the 10s of microseconds. Anything more accurate would need PTO and significantly more investment, but that is more accuracy than I'd ever need.

Cloudflare has worked quite well for me as a DNS host. You don't need to have the registrar host the DNS records.

jhart99 — Mon, 29 Apr 2024 10:56:52 +0000

Ahhh thank you! I was wondering why the energy had to be so precise. That makes a ton of sense why it has to be so accurate. What makes this transition so low energy? The only other atomic excited state I have any knowledge of is the iron excited state used in Mossbauer spectroscopy. That transition is much higher energy. Also that one has some coupling to the electronic state of the nucleus. Does this Thorium transition have some special reason that it isn't coupled to the electronic state?

I suffered burn out from the Y2K and dot-com bubble. Left CS and worked at a winery for a year and a half. I went to grad school for Chemistry and then did a post doc in Cancer Biology... 20-some years later, somehow that all looped back around to Data Science. I guess I left CS, but not really STEM fields.

I would guess that the goal isn't to increase the mass of cinnamon to but to interfere with a standard assay of cinnamon. This would be similar to the melamine in baby formula and milk powder scandal in China. The melamine wasn't added to significantly increase the mass, but to interfere with the protein content assay. The lead might be there to add color, to interfere with assay of organic compounds, to prevent fungal growth, or even to cover a defect(lead binds to stinky sulfur compounds)... It's hard to say with knowing what form of lead they found in the apple sauce.

I routinely rerouted my packages in San Diego since UPS wouldn't attempt delivery. You can do it with most packages unless the seller specifically has specifically forbidden it, (thank you Ingram Micro for sending me on a 3 day chase for my package)

Doesn't look like it will be a private action. We will still need to get the State Attorney General to initiate it which will mean nothing will happen.

Replication in many fields comes with substantial costs. We are unlikely to see this strategy employed on many/most papers. I agree with other commenters that materials and methodology should be provided in sufficient detail so that others could replicate if desired.

Costco has incredible leverage over their suppliers. I worked for a supplier previously and they forced changes to our packaging including labels, cases, and pallets to make things easier for them. I have no doubt that Costco could give HP or Sony an ultimatum like this to dictate functionality or just not carry their brand.

In that case, I would offer 3. The journal is trying to boost their stats. One wonders how long they thought they could have gotten away with faking articles to fill a journal...
