Not OP but I use motorized ball valves from Amazon [1] which are hooked up to a four way water hose manifold to create four different zones. It's wired up to an ESP32 that controls them with relays via GPIO, using the ESPHome sprinkler controller module (which does pretty much everything OP's code does). I've never had a problem with them and the last time I even touched them was over a year ago. They're pricey but you can DIY them.

The usual sprinkler valves at hardware stores need quite a bit of water pressure to change state which is probably what most people have a problem with, especially if they're trying to feed them with the kind of pumps they get at hydroponic stores.

Yes. But the list is too long to put in a message here. Generally tools which do things that I needed done at the time, like convert PDF bank statements into CSV transaction files that can be ingested by a simple ledger application.

I always have a 'hacks' directory in my home directory of code that does something I need doing. Sometimes I use it again and again, sometimes its a one-off that answers a question.

I'm more curious though about the motivation of the question. What was the observation that got you to wonder about this?
Entropy gradients are non explanations.

Pointing to statistical mechanics and saying the derivative of an exponent is an exponent is an odd way to explain qualia.
> Is tech really that uniquely sensitive to interest rates while the rest of the economy doesn’t care?

This is likely due to IRS Section 174 which changed how tech salaries can be expensed.
What a massive and impressive coverage. The author, Robert Kuhn of Closer to Truth (https://closertotruth.com), ends this beast with a request to readers:

> Feedback is appreciated, critique too—especially explanations or theories of consciousness not included, or not described accurately, or not classified properly; also, improvements of the classification typology.

I think RK would enjoy Humberto Maturana’s take on cognition and self-cognition. Maturana usually does not use the word “consciousness”.

Start with Maturana’s book with Francisco Valera:

Autopoiesis and Cognition: The Realization of the Living (1970)

The appendix of this book is important (“The Nervous System”). Last few pages blew my brain or mind ;-)

Thinking about consciousness without thinking more deeply about temporality is one problem most (or perhaps even all) models of consciousness still have.

Since Robert Kuhn works in thalamocortical activity the theme of timing should resonant.
Generally, there's more car fires than you'd think. Summary off google:

"Data from the National Transportation Safety Board showed that EVs were involved in approximately 25 fires for every 100,000 sold. Comparatively, approximately 1,530 gasoline-powered vehicles and 3,475 hybrid vehicles were involved in fires for every 100,000 sold."

That's 1.5% chance of an ICE car burning down, 3.5% of a hybrid. That's even higher than I thought.

I assume this is including accidents and they probably account for the majority of fires, but ICE cars also catch fire parked sometimes. Off top of head, there was a Mercedes GLS recall and the recent Kia Telluride/Hyundai Palisade recall due to car fires in drive-ways/garages when parked.

Not in Germany, but still in the EU, I'm one who complain not against "seat belt" in general but the approved three-points one, because they are DANGEROUS instead of being helpful and automakers know it but do not want to invest in 4-points seat belt and most people do not even know why they are dangerous OR useless...

I do not tell why now, because I'm curious how many guess correctly, if someone ask I'll tell why, and yes there is pre-modern-web research on that topic, buried of course, similar to various researches about seed oils, colza hepatic toxicity in particular, others about plastic films to wrap food and so on.

Again, then this law is totally harmless: if indeed people are biased when they decide if someone lies or not, it does not matter if there is a law on it.

Again: if you are claiming that this law will harm opposition, then you are not saying that "human are not neutral", you are saying that everyone involved in the process are magically all aligned in exactly on side. If there are people biased "in the other direction", then they will be biased to say the accused is innocent, and it cancels out.

As compared to which demonstrator that uses HTS? The people at Tokamak Energy are very nice, but the technology is far from ready.

If that is your standard, then everything we make or build is outdated right out of the gate because there are always fancy new materials that are better for whatever property you think you need. They are also: much more expensive, usually much more difficult to make, not really well known (there is still quite a lot of research being done on REBCOs), and nowhere near ready for any kind of industrial process.

All the research in the area is for the next reactors. It’s good to look ahead and to know that there are several improvements coming, but it’s not realistic to expect them to be here already.
Helion would make their own 3He, by DD fusion. No lunar mining needed.
The claim about the second is correct, the first not quite since there are a few mid temperature superconductors that do work in liquid nitrogen, and REBCOs are mechanically good enough.
Their problem is all the rare earths - and to make a magnetic containment fusion reactor you need truly massive coils. So you face a problem in price and availability of the materials...

>Specifically on Linux there are two system-wide sysctls: fs.nr_open and fs.file-max. (Don't ask me why one uses a dash and the other an underscore, or why there are two of them...)

Somewhere it should be lore that the person that named these syscalls went on to name functions in PHP.
it's weird but Visidata is very nearly my idea of a perfect spreadsheet. "But!", you exclaim, "Visidata is not a spreadsheet", I know, I know, that is what makes it so weird. Let me explain.

I am not fond of the the usual spreadsheet data model. "It's a big bag of cell" does not fill me with joy. And upon a bit of reflection I think it is the rows, I really hate how easy it is for rows to get out of sync. All I really want is row security.* And this is what visidata brings to the table.

* Relational databases provide this in spades. and in truth most of my spreadsheets have been replaced by them(I maintain a local postgres server on my desktop for all the small random prototype junk you would usually do in a spreadsheet using visidata as a pager) And while the database is great for analysis, random data entry sort of sucks. There are some great tools out there for this. I don't tend to use them, mainly because psql is always there, so I just sort of grumble when I have to do random entry without trying to fix anything. Why postgres instead of sqlite? I like the types and functions better.
I think a great intro to RPG for young kids (5-6 year-olds) is Little Wizards. It's originally French, but I have a version in English. It combines enough choice and customization to make it interesting, but without being too complex. It's a world where magic exists, but only kids can use it, so that was a plus for the kids :)

I knew it had to into a major vein, but I didn't know about the hunger issue with TPN.
P-zombies is a thought experiment to demonstrate the hard problem of consciousness, it is not, in itself, an argument against materialism.

I can certainly imagine a robot that imitates all of human behaviors. If you hit it, it goes "Ow" and retracts, if you ask it if its conscious it says "yes". We can this imagine being created out of our completely physical electrical components, so the question becomes what is the difference between the imitation of consciousness and the consciousness we experience? This is interesting as in this day and age, we can totally imagine building such a robot, yet we'd have a tough time believing it is actually conscious.

Now, whether you are a materialist or not depends entirely on whether or not you believe conscious experience like yours can emerge out of physical components.

My take on this is: Materialism/physicalism is ill defined and materialism/physicalism and dualism are compatible. We consider completely mysterious properties like energy and now even randomness (things happen one way or another for no reason) as being fundamental physical facts about the universe. Theoretically, how does this differ from saying consciousness is a fundamental physical property?

Moreover, you have to consider the fact that the "material" world IS an imagination of the mind. Whatever facts or attributes we assign to being material is limited to the mental facilities of the brain.

At the end of the day, the question is, what fundamental facts do we need to explain the observations that we make? I can observe that I feel, see, hear things. Can the fundamental facts of the current physics model explain this? No? Then we must add to it an additional property, making it part of the standard physics model. If you want proof, you must either A. explain how consciousness can emerge out of existing known "material" processes, B. Admit consciousness as a "material" property and define the process by which it combines, reduces, etc. (the combination problem of panpsychism)

In Wales, the place this law is discussed, it is not true that the winner has all power: the system is designed to give a lot of power to the opposition too. It is just not true that in Wales the opinion of the opposition is not heard or is considered as lies.

In fact, in Europe, the definition of democracy is more of a system where you accept that there are different opinions and try to work to a consensus even if you are a majority. Due to that, there are rules to protect minorities even if the majority don't like or care for them.
> We did launch a “true” dual core, but nobody cared. By then Intel’s “fake” dual core already had AR/PR love. We then started working on a “true” quad core, but AGAIN, Intel just slapped 2 dual cores together & called it a quad-core. How did we miss that playbook?!

it is wild the way AMD engineers can't stop themselves from throwing stones, even with 20 years of distance and even when their entire product strategy in 2024 now rides on gluing together these cores.

people forget that Intel saying that AMD was gluing together a bunch of cores comes after years of AMD fans whining that Intel was gluing together a bunch of cores - that was always an insult to Intel users that pentium D wasn't a real chip, that core2quad wasn't a real chip (not like quadfather, that's a real quad-core platform!). And you see that play out here, this guy is still salty that Intel was the first to glue together some chips in 2002 or whatever!

and the first time AMD did it, they rightfully took some heat for doing it... especially since Naples was a dreadful product. Rome was a completely different league, Naples really was glued-together garbage in comparison to Rome or to a monolithic chip. You can argue that (like DLSS 1.0) maybe there was a vision or approach there that people were missing, but people were correct that Naples was a dogshit product that suffered from its glued-together nature. Even consumer ryzen was a real mixed bag, vendors basically took one look at naples and decided to give AMD 2 more years to cook. People wedge still so wound into it they sent death threats to GamersNexus for the “i7 in production, i5 in gaming” which frankly was already quite generous given the performance.

frankly I find it very instructive to go back and read through some of the article titles and excerpts on semiaccurate because it just is unthinkable how blindly tribal things were even 10 years ago, but this shit is how people thought 10 years ago. Pentium D is bad, because it's glued-together! Core2Quad is bad because it's glued-together! And that from the actual engineers who have the perspective and the understanding to know what they're looking at and the merits, with 20 years of retrospect and distance! If you instead look at what the discourse of this time was like...

https://www.semiaccurate.com/tag/nvidia/page/6/

"NVIDIA plays games with GM204"

"how much will a GM204 card cost you!?"

"Why mantle API will outlive DX12 [as a private playground for API development outside the need for standardization with MS or Khronos]"

"GP100 shows that NVIDIA is over four years behind AMD in advanced packaging"

"NVIDIA profits are up in a fragile way".

like why are amd people like this? inside the company and out. It’s childish. None of the other brands engineers are out clowning on twitter (frank azor? chris hook? etc), none of the other fans are sending death threats when their brand’s product isn’t good. Like you wanna make a $10 bet over it???

Anyone who has kids has to answer the phone from strangers routinely. School staff and camp counselors are routinely using their own cell phones these days to communicate with parents.

Doing it the opposite way - tying all outbound school/camp calls to a single callerID - risks blending the important with the automated reminders. LAUSD abuses their automated calling system to the extent that my wife and I have both screened calls from the front office involving an injured child, more than once.

The real issue here is getting to the root cause, which is carriers and their intermediary aggregators having incentives to carry large volumes of spam.

In a number of markets, operators have increased the cost of SMS messages to deter spam, only to find a massive increase in traffic pumping fraud that mysteriously appears in the system of trusted intermediaries. Everyone's making a goddamn fortune off it, and no one actually cares to fix it.

You absolutely can do that. You still need a charging controller and a BMS, obviously. But you can avoid the AC round-tripping.
First link says

> No one has been arrested or charged

and you were claiming arrest

Second link: Police officers joking about raping, again no arrest for political opinion

Third link: racist and antisemitic stickers. Again, nothing political. Well if your idea of politics is blind hate then the discussion from my side is over.

You might say UK has censorship and no absolute free speech. That's true, but this is still miles away from prosecuting political opinions. I am not from UK but I am perfectly comfortable with prosecuting rape threats and hate.

Adversary of your government, not necessarily of yours. If at least your government kept the spying within its borders, you could reduce this to "us vs them", but USA spies overseas too, and brokes that information with its partner countries who also spy internationally. Accusing any other country of spying is ridiculous when everyone is doing it.

Show HN: Modern Portfolio Theory as a Service
Hello,

Some time ago, I created a free service: Quantitative API (Q-API).
Initially, it was capable of creating tearsheets and calculating portfolio metrics.

I have recently extended it to include Mean Variance Optimization with a walkforward approach to optimize asset allocations using PyPortfolioOpt.

I am demonstrating its use in the article through options trading strategies, but it will work with any asset: https://blog.deltaray.io/portfolio-construction-methods

The heavy lifting is done by PyPortfolioOpt and QuantStats.
The added value is the walk-forward optimizer plus the REST API.

I hope you find it useful and thanks for your feedback!
Delinking by itself isn't a heresy (no more than disassembly or decompilation), but what I do with it definitively is. Ripping out MIPS code from a PlayStation video game and shoving it into a Linux program, dismembering a x86 Linux program and turning it into a native Windows program...

It's when you get creative and throw ABIs out the window in order to create some cursed chimeras that this really becomes heresy.
In general norms are reasonable but just for instance my car ADAS today given me two phantom breaks, one for a reasonable reason (I was approaching another car fast enough knowing it will accelerate, but the car can't know that) another for no really reasonable reasons.

So well... I opposite such kind of deployments without a single, easy to locate physical button you can hit to "clear all ADAS pushing here" like an emergency button. Some examples:

- due to a health emergency you purposely want to ignore speed limits, and of course you do not want to waste time digging in car tablet preferences;

- due to a sudden emergency you need to ignore speed limits, like a landslide you see started dropping from above;

- you are actually passing another car and still at safe distance but quickly approaching another car appear in the opposite direction;

These are just few rares and far less rare examples why it's a good reason to pass limits and you have no time to deactivate the adas digging in some touch menus.
Yeah and where are those over unity results of their test reactor?

The other thing is that we do not care as much about the fuel, but the sheer masses of liquid helium as coolant. That reactor is not designed to capture the helium made for this purpose while staying energy efficient.

I agree - once you've settled your math on consciousness, you can go back and modify the priors based on new evidence. One of the crazier suppositions that actually makes a dent in the posterior probability is the simulation hypothesis.

If all civilizations that develop computation and simulation capabilities converge to the development of high fidelity simulations, then it's highly likely that they would create simulations of interesting periods of history, such as the period of time when computers, the internet, AI, and other technologies were developed. We just so happen to be living through that - I still put my odds of living in base reality somewhere above 98%, but there is a distinct possibility that we're all being simulated so that this period of history can be iterated and perturbed and studied, or some such scenario.

Maybe someone ought to start studying the science of universal adversarial simulation attacks, to elicit some glitches in the matrix. That'd be one hell of a paper.
I didn't say that the government followed the law or even did the right thing always. But in many countries you have absolutely no recourse. In the US you can talk about it, file lawsuits, etc.
