The system is clearly not "live and in use" without its dilution fridge and thermal radiation shields.

Built with asp.net and jQuery. Nowadays, it would probably be some React monstrosity that takes 30s to load and only shows one item per page (when did information density become evil?).

It's easy to overlook the sample memory spec. These old Teks have decent bandwidth and 1 GS/s, but only a few thousand points of memory. This makes it impossible to zoom into a captured trace and leads to severe aliasing (trap for

I hate the TDS2024 (early-2000s digital scope) with a passion. The LCD is awful, the power supply breaks all the time, and the sample memory is laughable compared to modern scopes, making it very difficult to use. Tektronix kept selling thi

In Europe, people use WhatsApp for this. Ridiculous to go through a chat app for this, but it works.

The hardware is very cheap (just a GNSS receiver), but this is a low-volume product. There are robot lawnmowers that come with RTK base stations.

The fuel is (almost) harmless, it's the fission products that make reactors dangerous. Many of those are water-soluble. Of course the fuel elements should be encased, but drinking pool water is probably not a great idea anyway.

I once worked in a nuclear research reactor, and they had lifebuoys at their pool. Quite prescient, as it turns out.

This is great! Having PDFs as a native image format removes one of the biggest hurdles for replacing LaTeX with Typst.

Yes, there is a limit called "quantum projection noise" that determines how much frequency stability one can achieve with a single-atom clock [1]. With N independent atoms, this limit gets smaller by 1/sqrt(N), but with N ent

This is true, but atomic clocks are about a million times more accurate than any other measurement device. For all pratical purposes, they are never the limiting factor.

The samples from the authors' GitHub are just some text vomited onto slides, and the AI voice reading them point by point. Exactly the opposite of a good presentation.

Yes, the dockered Windows 11 will start nagging you for a license keys after a while. I used some old Win10 key, and it worked fine.

I always used a Virtual Box VM for Office. After giving this a quick try, I'm impressed. The dockered VM is much less bloated then a normal Windows install, and somehow running the apps via a local RDP connection is significantly smoot

According to the list on Wikipedia, the existing reactors in the US are just a few different models [1]. Looks quite standardized to me. [1] https://en.wikipedia.org/wiki/List_of_commercial_nuclear_rea...

Why would you want to run a VCS in an embedded application? Any halfway usable development platform (even VIM) will be much bigger anyways.

The authors carefully avoid giving any actual efficiency figures (or figures from which the efficiency could be easily calculated). Since they barely managed to power an LED under concentrated sunlight, it is probably safe to assume that th

Watches tend to be exposed to light a fair bit, so putting a solar panel in the watchface easily outperforms a betavoltaic cell. This has been available for decades, and even some of the high-end Garmins have it.

The US Navy runs 50 MWe reactors inside billion dollar submarines. The requirements are almost entirely orthogonal to economically viable power reactors.

I believe that it may be misguided to focus on compute that much, and it would be more instructive to consider the effort that went into curating the training set. The easiest way of solving math problems with an LLM is to make sure that v

That decision probably paid someone's new car. The KPIs will be excellent. Who cares about what the users might have wanted to do with their clicks.

It is indeed an impressive feat of engineering to make the start menu take several seconds to launch in the age of 5 GHz many-core CPUs, unlimited RAM, and multi-GByte/s SSDs. As an added bonus, I now have to re-boot every couple of da

No, we do not have an absolute reference point for time. Our best models of physics are time-translation symmetric (this is equivalent to conversation of energy via Noether's theorem), so absolute time cannot have any measurable effect

The largest uncertainty of the Al+ clock is caused by relativistic time dilation due to the ion moving around a bit in the ion trap. This would affect a 229Th clock in the same way, but maybe the larger atomic mass would help.

These are optical clocks, so their rates are in the hundreds of THz to PHz range (1.121 PHz in the case of the Al+ clock). A 1e-18 shift corresponds to a ~mHz frequency deviation which a decent frequency counter can resolve in around 1s. Ho

LLM companies try to optimize their benchmark results, not to test the capabilities of their systems. This is why all the benchmarks are so utterly useless.

I'm all for making fun of LLMs, but asking this from a software that processes vectors of tokens is a bit silly. The information isn't really there in the input.

It's much worse, the maximum on-chain transaction rate is something like 7 per second. Also the time intervals between blocks have a huge spread, so it can take more than an hour for a transaction to be confirmed if you are unlucky. Th
