If you think this is what LLMs are, then you are a bit behind the times. Opus 4.5 is a huge step up. The previous generation was good for starting basic hobby projects, now we can do pretty big time-consuming changes with it.
I have been extremely skeptical and dismissive of LLMs for a long time, but after a certain level of improvement you have to realize that at least for programming the advantages are substantial.
Well, what would those benefits be? I genuinely don't see what it's useful for.
From what I've seen, people spend an inordinate amount of time typing in "prompts", and the chatbot goes off and pretends to generate some code, and then the people have to work out what's wrong with it and type in another prompt.
So it looks like the humans get to do all the slow, time-consuming drudge work of typing stuff in and debugging the result, but the chatbot does the interesting part.
Because then it doesn't alter the side of the membrane where it does the reading (plus one minus one equals zero). That makes the measurement more accurate.
Specifically, if you assume a partial pressure of Oxygen and of all other gases on the electrode-side of the diffusion membrane, then you'll only see a certain number of "ionization events" per time, and you're limited in how much electrical signal you get by how fast oxygen can diffuse across the membrane. This is likely driven by maintenance of a partial pressure within the membrane. However if you re-ionize the oxygen that you deionized, then the partial pressure is much closer to equilibrium, and therefore the partial pressures are only dependent on the amount of oxygen outside of the membrane instead of being dependent on both the ionization rate and the recovery rate through the membrane. It probably makes the calculation a lot faster and more closely dependent on the environmental presence of oxygen which is what you want.
It means you do an electrochemical reaction that releases an oxygen molecule, like the original explanation said. It doesn't really matter what reaction it is, but it could for example be electrolysis, where you split 2x H2O into 2x H2 and 1x O2.
The point is this reaction is reversible. In one direction, you end up with fewer O2 molecules than you had before. In the other direction, you end up with more.
How do you add the molecule? Well, you're not just dealing with single-digit numbers of molecules. Have an oxygen tank with a flow meter for example, open the valve to release the required volume of oxygen. The ideal gas law tells you how many molecules you let out.
How do you know when you have to do it? The sensor tells you how many oxygen molecules you consumed, as a proportion of the current flowing. So just let oxygen flow into the tank at the same rate as you're consuming it. Which you know because the device literally measures how much oxygen it is consuming.
I think the real issue is that the explanation in the tweet is from a physics perspective rather than an engineering one, which means it reads like it was implemented with impossible magic.
>open the valve to release the required volume of oxygen
Mega LMAO. I can assure you this is not what's going on, at all. Also, if you release oxygen in gas form into the liquid you're going to run into a zillion other problems.
One of the golden premises of measuring things is to avoid altering what you're measuring, lol.
There are a lot of explanations elsewhere in this thread. If you've read all of them and still don't understand, I don't know how to help you further.
Mainly I take issue with the person I replied to implying "I don't understand the solution, therefore there must be some functional issue with the solution."
It sure looked like he was a part of the organizing of the event. But you mean the organizers phoned him up and informed him that they were going to storm a church or something?
> But you mean the organizers phoned him up and informed him that they were going to storm a church or something?
Yes, probably. The whole point of protest is to be public and raise awareness of the issue. Getting a journalist to cover their controversial church protest is exactly what I would expect a competent protester to do.
I've also seen the "interviews" though. He's interviewing the victims of the harassment and he's not interviewing them, he's pushing the agenda. You should go watch them with this in mind.
> "Don has been a journalist for 30 years, and his constitutionally protected work in Minneapolis was no different than what he has always done," Lowell said in a statement. "The First Amendment exists to protect journalists whose role it is to shine light on the truth and hold those in power accountable."
I mean.. he posted the videos so we can all see that this isn't the case. Journalism doesn't normally produce the chaos that they report on.
I guess it is some kind of problem with the home-made counter (e.g., picking up electrical noise), or perhaps the counter is placed in a building with a higher background level.
As far as I’m aware, buildings made of blocks containing coal power plant slag have a higher background, but I don’t know how pronounced the effect is.
The normal background should be like 15–25 counts per minute for majority of Geiger tubes.
Well.. it's not a menu bar, which can be seen pretty clearly from the screenshots. It's basically only the left side of the menu bar with tools from the mac, not the menu bar itself.
django-seal offers optionality on this front. You can choose to use Django's default behavior or opt into sealing for when you're working on code where you _really_ want to avoid N+1's
If you're doing simple CRUD apps, try https://iommi.rocks/ which we built because imo it's way way too slow and produces too much code to use standard Django to make CRUD stuff.
