It's a certification requirement that the magnet can quench with a patient inside and the patient is not affected – the cryogens are supposed to vent outside the room, or, in the even that does not happen, at least safely within the room.

A blocked quench pipe and a stainless steel (typically A4 stainless) cryostat becomes a bomb: cryogens expand in volume by about a factor of ~700 when boiling and so the volume they occupy at 1 bar and 300 K is, well, far far larger than the volume of the room the scanner is in.

This is the sort of thing that is a (remote) risk to life. I've only ever seen one (preclinical, not-for-human-use) magnet unexpectedly quench; copying and pasting a paragraph from my PhD thesis:

*The overpressure created by the rapid boiling of the large volume of liquid helium surrounding the superconducting magnet was sufficient to burst the bursting disc (as designed), which allowed the venting of helium gas from the inner cryostat to the emergency quench pipe (the bursting disc was temporarily replaced by clingfilm in this photograph). Additionally, it was also sufficient to rip and blow off the quench pipe, break two windows, damage the floor, and relocate several light items within the magnet room (which, presumably, was not as designed)*

Eliza in the 1960s, and all it does is parrot back words. The participants just didn't know about computers and used their best explanation that they were talking to a human.

The Turing test aims to show that the AI and human are indistinguishable. But what it really shows is that it's not normal to question whether you're actually interacting with a human or not. Even if a homeless guy shouts nonsensical words, it's weird to wonder whether they are actually an AI.

Once you know there is a magic trick at play, then it's trivial to notice the difference.

How so? I’m genuinely curious as a current Tokyo resident.

The main issues Vancouver seems to face are:

Affordability and Housing Crisis: Tokyo is a remarkably affordable city given its status. There’s housing stock at pretty much every price level.

Homelessness and Street Disorder: not a problem in Tokyo

Drug Addiction and Overdose Crisis: not a problem in Tokyo

Traffic Congestion and Transportation: public transportation is stellar in Tokyo. Traffic can get pretty crazy at rush hour, but I hear that’s been the case for a long time and it’s not much of a problem if you use the aforementioned fantastic train system.

FWIW, I left San Francisco after close to 15 years due to the issues above. Tokyo has its problems, but they don’t seem to be in the same category.

Great post, happy Lunar user here!

I followed a kind of reverse path in a way: I ran my own small business for some years (first with a partner, then solo) but I eventually got burned out due to the feeling of being always-on. I’m now in contractor mode but working mostly like an employee for every project I participate in, and this did work better for me financially and personally too.

That said, I always think of maybe trying my business again (though I wouldn’t have employees next time around) and now that my daughter is about to start University doing animation and video games, who knows, maybe she needs a programmer one day and I can be that guy. That’d also help her work for herself and not be an employee. Thank you for an inspiring post!

Also, I somehow didn’t know about rcmd. I feel frustrated by cmd tab since ido-switch-buffer in emacs has spoiled me; it seems rcmd is close to that for task switching so I’ll give that a try right after my current vacation, so I’ll be a user of another software by you :)

Well, good luck convincing anyone to merge all config and mutable state into the same place (that should be fun, especially the user-specific config/state) :)

> NixOS's handling of state is poor. Even ignoring the problem of it all being spread out it is not uncommon for secrets to make it into /nix/store which is world readable.

The secrets handling is a well-known issue and easy to avoid when you're familiar with Nix. Although yes, it can be a problem when people are not aware of it.

And I disagree with NixOS's handling of state being poor. Apart from this "secrets" problem you mentioned, it's not worse than other Linux-based operating systems and in fact it can be argued that it's significantly better.

Just the fact that /nix/store is mounted read-only is, on its own, already a huge improvement over letting users and applications installing and modifying the system in an ad-hoc fashion (good luck when you upgrade your system!).

Not to mention all the other advantages of /nix/store (such as user-installed applications, no package or library conflicts even if you install multiple versions of them, etc).

And as another example, the `stateVersion` feature is something that also makes upgrades a lot more reliable, and I know of no other operating system that has a similar feature.

Atomic configuration changes, booting into specific configurations, and system-wide configuration roll-backs (configurations which also include changes in package versions or even entire OS upgrades), also makes upgrades and configuration changes easy to try / fix if anything goes wrong. No other widely-used operating system has such a reliable configuration change mechanism, as far as I know.

But, you know, if you have other ideas of how things can be improved (apart from your idea of merging user and system-wide state into the same place, which I think makes no sense), I would definitely appreciate to hear it!
I want to use meilisearch but it takes up more disk space than I'd like unless that has already improved.

I do medical risk assessments professionally and this is not at all how it works at all.

Most FDA approved medical products have inherent risk, e.g. X% of people will die.
The question is actually about how the actual performance aligns with disclosed and approved risks.

If Y% of people are hurt, the expectation was X%, and Y>X, then this is grounds for a penitential investigation and potential recall.

If it actually worked the way you stated, these machines would probably never have been recalled.

I do not work with MRIs, but I work next to the guys who run the NMRs (which is the ~same technology). It is my understanding that all of these super cooled magnets are designed for the eventuality of an emergency quench. Which means the machine has a direct path to evacuate the gas, and it should be piped into the building's HVAC so that if a quench does happen, the people in the area do not suffocate because of lack of oxygen.

A surprising amount of maintenance can occur while the magnets are cold and energized. My armchair-uniformed-guess is that they can replace the not-always-working relief path without venting.
Thanks for sharing your story. Switching from a tech to a "non-tech" (if you allow) company doesn't sound like an easy decision. I assume the NPO must have a vision and/or a purpose that attracts you. Do you mind sharing some of the reasons that motivated your switch of career?
This reminds me of that Zen proverb “Before enlightenment chop wood, carry water. After enlightenment chop wood, carry water”.

The simple and even tedious things in life are worth embracing and engaging in whole heartedly and with all of your attention.
A bursting disc is commonly used -- the diameter of the quench pipe is typically around 20 - 30 cm. The gas flow rates are insane; a PRV would fail and likely still not reduce the pressure inside quickly enough.

Remember, cryostats are like Russian dolls suspended on torsion wire. You want the mass of the metal inside to be as low as possible because it forms cold bridges to the outside world and increases the boil-off rate. Quenches should not happen once the magnet leaves the factory, but until that point it's not uncommon for a machine to have several "training" quenches as the (typically NbSn or NbTi) superconducting wire effectively anneals in place. A fixable giant hole in the top (with a graphite, insulating series of bursting discs) is the approach usually taken.

Return the full name and the link to the reference as a JSON object with the keys "first_name", "last_name", "link_to_reference". Return "not found" in case you are not able to disambiguate the initials. Do not return anything else.

JSON input:

ui.render()

> I can't tell if your comment is a parody, or if the "free speech absolutists" have really gotten this ridiculous.

Yes, I believe in free speech. If you believe this is ridiculous, it's on you.

> You think literally blasting someone in the face with dangerous smoke ... Potentially blinding someone ...

Now you are being ridiculous: the "danger" of this smoke is very relative: yes, particulates can be hazardous to health, but only in the long run. It's not like throwing acid at someone: it can't cause blindness!

This smoke may only reduce visibility a little and very temporarily unless it's done in a tunnel.

I think it's not a nice thing to do (pollution etc), but I still prefer having laws protecting important concepts like free speech, even if these laws also let people do things I don't like: the concepts these laws protect are more important that the consequences of a few isolated individual actions.

Also, intention matters: if the person doing that is aiming at cyclist faces or focusing on tunnels to risk causing accidents, it's very different from sending smoke towards the open sky and away from anyone: one is malicious and illegal, the other is expressing a political opinion and may be protected.

It's ok to dislike some political opinions, but it's not ok to try to regulate speech with the power of law.

Personally, I found switching to liferea (an RSS reader) to track the YT channels I cared about, and generally avoiding using recommendations was a path to satisfaction. I spend very little time scrolling through YT now. Most of the time, it's liferea that tells me a new video is out that I almost certainly want to see. However, the recommendation engine works quite well for me, and so when watching the video I did actually want to see, I will see the right-side suggestions list and every so often, there's something good/valuable there).

I think battery storage costs something like $100/MWh or 10 cents per kwh. (Don't quote me/find a reliable source). Batteries increase demand when there is excess supply and increase supply when there is under supply. The result is lower price swings. The price differentials are higher than the cost of storage which makes them balance sheet profitable. The notable thing is the buy low sell high cycle is 24 hours, not weeks or months. From an arbitrage point of view that's exceptionally attractive. Better than buying wheat futures in the spring and trying to offload them in August and sometimes losing your shirt.

I love through-zero frequency modulation (TZFM).

If your oscillator can do TZFM you can bring it’s frequency down to zero, where it stops oscillating and then to “negative frequency” where it starts oscillating again, but with a reversed waveform.

This has two main usages:

first you can do normal FM sounds with very deep modulation without getting strange pitch shifts because the frequency is capped before zero.

Second, you can set the oscillator to start at zero and then modulate symmetrically around zero. The sound you get is quite unique — ranging from woody sounds to growling lead sounds. The fundamental pitch is decided by the modulator (as opposed to the carrier in usual FM). Symmetric TZFM takes the modulator signal and integrates it, then adds harmonic content by folding
according to the waveshape of the modulator. This works best if the two oscillators are kept in soft or hard sync.

My favourite patch is to use a harmonic oscillator as modulator for a TZFM carrier. Modulating the distribution of sines in the modulator and the frequency of the carries gives such a unique set of timbre controls.

Yes. The more I browse though the NAICS hierarchy, the more I feel uncomfortable excluding hardware-heavy companies like Garmin.

On the other hand, it also context-dependent. Let's say you're looking for a job opportunity as a software engineer/developer/programmer/..., how much priority would you put on whether the company has tangible inventory?

No. In asymmetric warfare civilians are targeted partly for animus but mostly because of accessibility. Poorer security places extra pressure on the enemy government which makes it easier to destabilize over time, in theory. In the case of unguided missiles it's natural to point them at wherever the infrastructure is dense.

If you have the resources to be selective, it's much more attractive to hit specific targets like military facilities or political figures/institutions. Terrorist attacks are more often perpetrated against civilians nowadays because political/military targets are so hardened that assassinations are difficult.

This so untrue I had to make an account to reply to you.

Quebec french is standardised by the OQLF (Office Québécois de la Langue Française) and the formal/informal distinction is as important in our french as it is in other cultures. The reason it might seem less common is because most conversations people have are informal. In formal settings, it is still expected of people to use "vous" rather than "tu". It is seen as polite and some people might even take offence to the informal being used when they do not know their interlocutor personally.

I think it will stay that way for the foreseeable future (but who can say). Ways to fix the particular hole:

(1) disable creating new `code` objects directly from Python. This probably would break lots of things.

(2) Add a bytecode verification mechanism that would reject `code` objects whose bytecode would result in memory errors when executed. This could be a lot of implementation work; I'm not sure.
