What companies value can change after they’ve grabbed their share. Just like how OpenAI changed their “constitution” about working with others.

I wish there was a way to hold companies accountable for stuff like that.


Zulip being fully open-source and self-hostable helps this. It's what the Bluesky team have been calling "credible exit", and Zulip has it way more than Bluesky does.

On the other hand, I would love to see more tech companies being co-operatives, where their members get a say in governance. That'd be the ultimate hard-mode for a business that was dedicated to being rugpull-resistant.


Agree on wanting to see more tech companies being cooperatives but not sure what you mean by this:

> That'd be the ultimate hard-mode for a business that was dedicated to being rugpull-resistant.


Being a cooperative seems (having never run one) harder than being a regular private company. It seems like it would constrain a business from being able to do what it would otherwise want to do. So I think of it as doing business "on hard mode". I think it's socially worth doing, and I aspire to be part of one someday. But I don't think it comes for free, especially in a market where you'll compete with businesses that aren't also playing on hard mode.

I see, I agree with it too. I think that's why many tech projects prefer a "private company owned by a non-profit foundation" structure such as Mozilla and Signal as the examples off the top of my head.

How come you don’t just send the md5s to delete rather than the shell script?

I guess it's a more flexible design that allows to change the criteria for deletions in the future. You still need to calculate md5s on the phone either way.

That would definitely work too.

What I like about my process is that there is only one source script (the python one) to keep around.


Power plants are often described in terms of (max) power output, i.e., contribution to the grid. So, I can see how it might confuse a writer to then also talk about storage inadvertently.

But also, the second paragraph already describes the 100 MWh vs MW nuance.


It is not a nuance in an article that focuses on storage from the supposed premier professional association. As an engineer I would expect typical energy content (median/average) of the top 10 hydro pump projects and also some discussion about the availability of suitable sites. I think one should strive for at least high school level physics. There is no need to push out texts that can be easily surpassed by any current llm.


Indeed. For a sorting algorithm it would be more insightful to show it test the actual property of something that is sorted: every consecutive element is larger than the previous one (or the other way around). You don’t need a sorting function to test the “sorted” property.


Can you elaborate a bit further on what you’d need to do and why? It’s been a while since my electrical courses.

I’ve been trying to measure home power consumption with these plugs (and the ones from IKEA) but I’ve been getting suspicious readings for inductive loads.


I wouldn't bother using a smart plug. The other thing that's real dangerous about them that I didn't really elaborate on is the relay. There's a reason on something like a pump, fridge, AC unit, etc. you'd see a real contactor instead of a relay, and it's because relays are inappropriate and have dangerous failure modes for big loads like that and are typically way too small.

In most real non-resi situations, you'd probably isolate the hot leg and put a good CT (current clamp) on it and read that. The great thing about that is you haven't added anything in the power path for the device, like a shunt which is what most smart plugs use. Current clamps are good for a lot more current (though I guess a proper shunt could do it too). The easiest way to do this in your setting is to find a good UL-listed electrical box with cable glands, a short piece of DIN rail, a male and female plug pigtail, some proper THHN wire and wirenets and a Shelly 50A EM Pro, and just graft the EM Pro into the box and wire it up with it's CT. You've now got something signficantly more durable and probably safer (and correctly specced for the load). I've done other things like using an HV Labjack and some good CTs or other one or few off designs. There's lots of stuff in the commercial/industrial space that does this well but it tends to be $$$. Again, for the sake of my own family, I wouldn't use non-UL stuff (most plugs and things that go in gangboxes that are "smart" aren't UL listed, and MAYBE are ETL) as you who knows how much or how well it's tested.


The IKEA plugs have a tidbit in the manual that says a "motor load" is limited to 300W while a resistive load can reach the full 3680W (at 230V, probably less if you're in a lower voltage country).

Should be fine for modern fridges but older fridges may overwhelm the circuitry.


Yeah. Using the Kalman filter just to determine the position from noisy position measurements really undercuts the capability of the filter to use system physics to estimate the true state.

In one of the most common applications of Kalman filters, autonomous robots (e.g., a robot vacuum or a commercial drone), the filters are around 9 to 12 dimensions.


Right, in addition to the position you usually want the velocity, and sometimes also the acceleration, in all dimensions. More ambitious (or optimistic) practitioners could add more sensor measurements, like gyroscopes.


You are right of course and I was out of my depth. I wonder if the vector types now being added to databases for ML/AI stuff could help with this.


The number you are seeing is the (USD) price you would pay for one ounce of gold right now. (Not taking spread into account.)


I figured it out! I disabled scripts so the code of the website never ran. Now am not highly unique! (Neither am I “not highly unique” though.)


We designed a processor microarchitecture [1] at the University of Cambridge, inspired by Uncertain<T> (James Bornholt) and related work. In addition to assuming parametric distributions (e.g., Gaussian, Rayleigh), it lets you load arbitrary sets of samples into registers/memory so program values are carried and propagated as nonparametric distributions through ordinary arithmetic.

A spin-off, Signaloid, is taking this technology to market. I'm also researching using this in state estimation (e.g., particle filters).

Out of context, the expression "the uncertainty in the number of trials" would refer to missing knowledge in terms of how many trials actually ran.

In the context of the post this doesn't make sense, so the reader is left to hypothesize what the writer actually meant.


I agree it could be clearer but as a general rule, if you find an interpretation under which the question doesn’t make sense, try considering another interpretation.
