left-struck··on Fable 5 On Vending-Bench: Misbehaving, With Plausible Deniability
Vending-bench sounds like it would be really fun to play/interact with as a human!
left-struck··on Completing a computer science degree on Coursera
Huh, I was doing a mechanical engineering degree at the same time as working on a engineering team and when I was doing exams it struck me just how distorted the exam is from reality and how it selects for a completely different skill set.

So you’re going to put me in a room, under extreme time pressure, where I can’t access the internet, reference books, modelling tools or talk to people?

Versus an office where you often have to collaborate, or ask for help or approval from someone more senior, where important decisions are reviewed over and over by multiple people? Where you need to use tools like the internet, books and modeling software. Where you need to talk to people whether they are engineers, business people or machinists.

Not only that but exams I think are better for people who are good at solving mostly math problems quickly with reasonable accuracy, where as most mechanical design roles require intense attention to detail that rewards taking your time to make sure there are no mistakes made. And most mechanical engineers end up being projects managers anyway I suspect in my country.

left-struck··on sqlite-utils 4.0rc2, mostly written by Claude Fable (for about $149.25)
Yeah when these models find a bug i like to ask it to write a test that will fail if the bug is real and pass when the bug is solved.

It’s not perfect but usually it works pretty well, and I’ve had the model come back to me with oh actually the test passed, the bug doesn’t work exist

As a bonus, you’ve now got a test that can detect that bug if it comes up again.

Tbh I suspect this is a bit of astroturfing, but what I don’t understand is why?

Complex conversation function? I don’t think it gets much simpler

Would you mind sharing these links? Or a subset? I want to grow my collection which is tiny because I started way too late
left-struck··on Giant trees have no trouble pumping water to top branches: new research
The 10 metre thing assumes you have a suction side which is 10 metres lower than the pump, or at least a suction that is long/low enough that it can’t meet the pump’s NPSHr (Net Positive Suction Head required).

In a tree the inlet to the “pump” is at the base of the tree. It’s not like there’s a pump sitting in the tree at 80 metres trying to suck water up from the ground, that would obviously fail. It’s more like a very long pump.

I think you’re confusing something being permissible with something being fair

It’s not a contract, a contract requires an exchange of value both ways.
left-struck··on Internal Combustion Engine (2021)
> fun fact: modern cars release so little carbon monoxide, you won't kill yourself by starting one in a garage

Modern cars still release as much CO2 as older cars… which is still incompatible with human respiration.

left-struck··on Internal Combustion Engine (2021)
It’s because of the good enough precision at low cost that we use cams, it’s extremely difficult to get precise movement and the forces and speeds required when an engine is operating at >5000 rpm. It’s not impossible but the trade offs are rarely worth.

The exact valve timing isn’t really a big factor in emissions as much as temperature control and exact AFR control. I mean valves need precise timing to avoid coming into contact with pistons but if you’re already at that level of precision then you gaining more precision won’t really reduce your emissions.

Of course being able to change the timing of your valves helps with both efficiency and emissions, but VVT does that pretty well.

Why stop there? vary everything that can reasonably be varied slightly across each resume
left-struck··on My Mathematical Regression
I think a better way to think about it is that humans in general just make so many mistakes and imperfect judgements. Smart people just do them slightly less. Smart people also typically have biases as well which affects their judgement, their basis are just more complicated than normal people. Like obviously being smart is an advantage for any decision, but saying if someone smart does something it must be smart makes no sense in a world where smart people usually can’t agree on what is right.
left-struck··on Unauthorized alert sent to cell phones across Brazil
I read this as the implication being that at least some people’s phones would still be on them, and it would suddenly be very obvious.

Which incidentally, how do you enforce a rule like this without serious security like pat downs or metal detectors? Because otherwise you could easily sneak a phone in through the sophisticated hack of owning two phones…

Buy a used car from a few years ago… do some research and make sure it doesn’t have anti features. This is the only option until manufacturers stop this crap

left-struck··on Banned book library in a wi-fi smart light bulb
If I, as a person who is firmly opposed to racism, wishes to read the Turner Diaries, why shouldn’t I be allowed to? Do you really think some stupid book by some racist wackjob is going to sway my deepest values? Can you not imagine a legitimate reason why I would want to read such a book? For example, to see what these people are thinking so I can be better prepared to answer their arguments if I’m ever forced to argue with one?

I understand your discomfort with these books, and I actually agree that they deserve to be banned, but banning is not what we should do.

left-struck··on Windows 11 users are tired of MS account requirements creeping into everything
Oh man, unfortunately all the things I need windows for doesn’t work well in a VM:

Solidworks, needs special license to work in a VM that my company is not willing to pay for

DAWs, need real time access to low level audio stuff

Games, well, lets just say the experience is better with wine on linux

With the exception of work, at some point I decided that not only is windows dead to me, but any application that can only run on windows is also dead to me.

That’s crazy, surely it would have been cheaper to buy a new laptop at that point. I mean if you combine all the costs of those people trying to problem solve, plus the opportunity cost of you not being able to do your work…
left-struck··on Statement on US government directive to suspend access to Fable 5 and Mythos 5
Is it fine though? We’re definitely seeing some huge negative impacts from AI use. Of course some positive ones as well, but the point is that they were right to be concerned.

I have to wonder if their aggressive guardrails were because they had a specific reason to believe that this was coming.
left-struck··on Nobody ever gets credit for fixing problems that never happened (2001) [pdf]
I think because it’s a negative feedback cycle. So once it starts it’s hard to go back, the deeper you are the harder. A trap is something that’s easy to get into and hard to get out of.
left-struck··on Various LLM Smells
Yeah, I think in this case, pointing out what’s obviously llm is genuinely useful since it will lead to more diversity in websites and a better tool. I mean I don’t usually care if a website is LLM generated as long as the copy is human written

Just don’t read anything on there, don’t need regex for that.
left-struck··on That Methyl Methacrylate Tank
If you shoot and pierce a vessel that is pressurised, especially if it’s near its pressure limit anyway, it will explode. Even if it’s just filled with an inert gas.

Actually even just making a hole by any means will significantly increase the chances of an explosion. This because the smallest crack can start a chain reaction where the material at the leading edge of the crack is bearing too much stress and the bonds break which then passes the stress on to the material straight after that. This all happens very quickly and can even accelerate as the hole grows bigger and gas starts moving.

It’s very lucky that the crack that formed didn’t propagate like that. It could be for many reasons though, like the crack front could have run into thicker material or a weld line or something like that and if luckily stopped the crack.

left-struck··on Spotify will start reserving concert tickets for fans
Well it seems like it’s still an excellent idea to have laws like this in place but like you say also have some tickets that sell at an auctioned price
left-struck··on Removing the modem and GPS from my 2024 RAV4 hybrid
>Gas stations with cameras.

Everything has cameras these days. On my street almost every house has a cloud connected camera. Every major road has cameras, every store and business. Now I’m not suggesting we give up the fight for privacy but avoiding gas stations does nothing

left-struck··on The locals don't know
My own experience has been that the average quality, and especially the like floor of the quality of food here in Japan is pretty high compared to Australia. What you get compared to what you pay for is especially high in Japan’s favour. But perhaps you’re right that the hype is not deserved, if you’re coming here expecting a heavenly experience then you’re probably going to be disappointed purely because of unrealistic expectations. I would say tourists from wealthy western countries should expect decent food for a great price. Touristic places might have higher prices though.
left-struck··on The locals don't know
I see what you mean, the thing about food in Japan though is that the minimum quality is pretty high. So I can’t really recommend a specific grocery store, all of the major ones have decent quality ready to eat food that just needs to be microwaved. (They usually have a microwave in the front of the store). Convince stores as well. I’m originally from Australia and so that’s my point of comparison, a convenience store karage bento here in Japan is similar in quality to a Japanese restaurant chain in Australia, but the price is like 1/3rd.

As for actual restaurants, I think the mistake tourists make is trying to find the best ramen or whatever, but the best isn’t going to be that much better than the average joint catering to locals. So in other words, spend less time thinking about where to go and just explore and pick a random place that you like the vibe of, that’s what I do and I’ve never been disappointed here.

I don’t really have time to say all that to every tourists that asks though lol.

Also I’m literally writing this from a random ramen place I walked into, and it was delicious!
