It works, but you loose some more energy. Better still is to make fertilizer with that and ship that out.

Shipping ammonia half way around the world with the intention of using it as a fuel doesn't make sense from an efficiency point of view. You loose so much energy creating the hydrogen, transforming it into ammonia, shipping it around, and then turning it back into mechanical or electrical energy, which again is not super efficient. By the time that is done, you are looking at maybe 10% efficient (possibly way less). So, it's a very costly way to move stuff around using ammonia as a fuel. Nice that it works but unlikely to be a preferred solution aside from some niche use cases.

And while ammonia is better then hydrogen in terms of volumetric density. It's still about half of what lng gives. So, you need two ammonia ships for every lng ship to deliver the same amount of energy. That same property also is an issue with bio kerosene vs. ammonia in planes.
I'm probably one of those people. I first came upon his writings while researching text editors and CLIs. It was all under the umbrella of a design, called "The Humane Interface". I agreed with him about somethings, like the universality of text, and the importance of undo, but disagreed with him about others like "modelessness" and file/program organization.

I can tell you why the Canon Cat never caught on with me. I don't recall ever hearing of it. Maybe I forgot. this was all a long time ago, circa 2000. Overall I did respect the amount of serious thought he had put into text-based interfaces and tried to hang onto what I thought was valuable, but I didn't buy into the system as a whole.
This is so very much worth reading given the context.

That doesn't make it illegal? If they don't want to talk to you because you entertain those ideas, that's just them using the right to freedom of association. It doesn't make entertaining the ideas illegal.
It's way better when you learn the words. Now I understand it's about frequencies and channels.

DFS to a software crowd will always expand to depth-first search. I was trying to figure out if that's what was being discussed here (with plenty of skepticism, admittedly) until reading GP.
Yeah I wasn’t expressing myself clearly, let me try again.

HTMX writes quite a bit of the logic for us. We don’t need to test that logic because we can assume that it’s been tested. We only need to test the remaining logic, of which there is less and it’s less messy because it’s more declarative (if I understand HTMX).

If we use an input of type “email” we also don’t test if its validation works.
Modern vehicles have high quality oils, tight tolerances but rpm dependent oil pumps. At idle, the oil pressure is lowest, the fuel energy is lowest and consequently the engine will take the longest to come up to operating temperature.

FYI
There seem to be more people calling themselves communists and supporting communist ideas in the USA, than there are who promote violence toward minorities. And I do mean actual or very-near communists, not people who want a social safety net and health care.

Although of course, attempts are made to associate broader and broader statements with extremism, such that even having an immigration policy at all is interpreted as racism, so the number of supposed racists is dramatically inflated.

If the right similarly broadened it’s interpretation of statements, 80-90% of the country could be claimed to be communists, for supporting the most minimal state assistance of the poor, which almost everyone does support at some level.
I use Raindrop for personal/hobby stuff and Zotero for pieces related to my research. I used to use Pocket and Instapaper but both of them became filled with ads and popups. The performance of Raindrop on Mac is questionable at best but it remains the best service I have tried in recent years. I've heard a lot good about Matter buy my guess is that their VC funders will push them to adopt $XXX/year subscriptions soon, which is certainly something I am trying to avoid.
Of course those inefficiencies multiply. You generate hydrogen at 30/40% efficiency. You generate methane from that at a similar efficiency. Then you compress it ... which takes energy. You ship it around. Which takes energy. Then you burn it at 40% efficiency. Numbers rounded up here. Real world efficiencies are worse. Multiply all of that and you end up with efficiencies of a few percent. Nice that it can be done at great cost but there are a lot of things that are probably more efficient and cheaper.
Employer often selects the arbitrator and is therefore a repeat player. This sets incentives for the arbitrator, no matter how fair they intend to be.

Also, pretrial discovery is much broader in a class action, so much more expensive. The procedures available to a plaintiff in an arbitration are much more limited.

But big picture, it’s better to have more options rather than fewer.
It can be trained some form of trustfulness, and a measure of certainty is intrinsically part of the model (compare with image to text models etc "70% cheetah 10% dog")

In any case it can be trained to assert confidence via a side channel
How does copying the first paragraph of the linked README and adding three words improve the conversation?
Another description: "dynamically picking channels to avoid radar activity". Seems more fitting with this one.

Why? I'd bet most people wouldn't mind at all.
And they wrote the GPU driver in Rust. Really pushing the cutting edge tech on this project. Unbelievable work.
yeah for a language model it sure did have a lot of opinions all the while professing to have none...and once a session gets stuck in a rut, it turns into a moody defensive model which then gets a bit funny sometimes.
> If this was a Chinese message board or Russian message board, I could make opposite predictions and be met with much more interesting debate and intellectual curiosity, as their information control mechanisms aren't nearly as sophisticated, and as a society they tend to be much more pragmatic and intellectually curious.

How do you mesh this with the fact that you can and will be arrested in Russia for calling the war in Ukraine a war, or for even protesting with a blank sign?.
They actually went the other way and released some extra features that only serve to make alt OSs easier and do nothing for macOS.
Please do not put words in my mouth. Calculus is currently an AP / college subject, not a required public education one.
Do you mean the touchbar? Yeah that’s a problem. Apparently the touchbar runs a whole instance of iOS. I don’t imagine support is going to be easy.

The one thing I want is operator overloading, so I can write vector calculations in a natural way. But this would need differing behavior depending on types, which is something the developers don't want to add in principle. They say it has to be added in JS first, but this is something that makes not much sense in JS but is possible when you have type information at compile time. (You don't want to add the penalty of dynamic dispatch to every addition, just rewrite v1+v2 to v1.__plus__(v2) when you know statically that v1 and v2 are Vectors.)

I thought about implementing it myself (maybe as a babel transformation) but I couldn't figure out a way to access the type information.
Just so we’re clear, Matt Walsh has never said any of the things you straw manned, he has never called for violence against anyone, explicitly or implicitly, I’ve seen many people call for violence against him.

In one breath you decry the supposed calls for violence against your chosen victims and in the very next sentence claim you must commit violence against others because it’s your only option. Do you not see the extreme irony in that?

You’re saying not only are you alone allowed free speech but also you alone are allowed to decide when to commit acts of violence, lest those you disagree with are allowed to speak and say something you find unacceptable and thus “verbal violence”.
No thats not the main issue. Most of the issues come from crap batteries not being anywhere near fit for purpose. I’ve swapped out enough (tens of the things) to see that as the average case.

Most laptops just whine about third party batteries and you can just nuke the vendor battery junk to get rid of it.
I am greatful for this summary, as I usually check the comments before the link, to see if its worth to click through the cookie consent and Ad spam found on most sites, as well as digging out punchlines from lengthy articles.

I just did a bit of reading on wikipedia about Semmelweis, and I think there is an interesting wrinkle which is normally left out of the Semmelweis tale. The effect size from handwashing was huge, but even Semmelweis couldn't explain why it worked. Handwashing only ended up catching on later once we had the germ theory of disease.

I wonder if a good modern analogy for Semmelweis would be if we did a study on crystal healing or Reiki, and the crystal healing/Reiki was found to vastly outperform placebo pills. (Actually something like this sort of did happen with parapsychology. The effect sizes were pretty small I believe, though.)

Obviously in hindsight, other docs still should've listened to Semmelweis. What I'm trying to get at here is that sussing out the truth can actually be a pretty tricky thing. Even if the docs had somewhat good reason to accuse Semmelweis of spreading medical misinfo, it was still a catastrophic mistake in retrospect.
The linked site is GitHub which has neither of those things.
The more interesting fact is not that she was a woman, but she was an accomplished Hollywood actress with no formal training that went on to invent the channel-hopping technology used in Wifi, Bluetooth and military radar installations, among other inventions.
Oh, I saw a video in 2021 in which a retired doctor/uni. prof. explained AZ complications (it was someone from the UK) were most likely/could be related to how nurses handled the needle and where they stung it. Like, he was concerned about the lack of instructions given to vaccinating squad. I blacked this info out because it was too much of a yet another thing I had to watch for at the time on top of others but for my first booster I had a chat with the nurse about the dosage of the booster and... yeah... better check these kind of things out yourselves, things can go wrong really fast (and mark your legs and operation instructions on your body before going under the scalpel :).

Edit: not sure if it's the video I watched but it's definitely the guy https://www.youtube.com/watch?v=nBaIRm4610o

I'd feel a bit guilty about remapping somebody's Windows keyboard if I was using their machine for some reason, since even if I had my own user account, the key mapping solutions tend to be global. They'd end up mystified about why the caps lock wasn't working, and it would be basically impossible for them to fix.
Oh I agree with that one entirely. One reason I buy apple shit is last year I got them to stuff a new battery in my old 6s which I bought in 2015 and they did it there and then in store. Second swap it has had.

Here is what I would want from a bookmark manager:

- Independent of the browser.

- Local (no cloud).

- When adding a new bookmark, a readable, entirely offline copy is stored (something like the SingleFile plugin). This is used as a fallback in case of link rot.

- Good tagging and organization tools.

Does anything like this exist?
Might even be easier than that. You'd want to test for the specific antibody, far too many people have the gene:

In my experience as an ISP 95% of small businesses have no money or inclination to hire someone such as yourself to architect their LAN, sadly, resulting in worse results for them. They just buy whatever has more spikey antennas at best buy and hope it works.
The brand I use has a drop down menu to select from.

Also, regarding WiFi equipment. Finding out the quality of consumer WiFi gear is near impossible before buying, because of so many other factors affecting wifi performance (especially that I use mostly 2.4ghz). If anyone has a foolproof method for this please let me know.

In context of GPT3 this video made me think how deep this problem will become, when there is no such thing as truth in the internet
Svelte stores. Mainly because the docs are practical and not a lecture about state management or functional programming and secondly because stores come with Svelte.

React seems to be drowning in its own complexity these days. As another poster points out you can do global state by observing an object on ‘window’, that most react state management tools make this more complex rather than simpler is concerning.
Interesting piece. One might think that abandoning the maelstrom of modern life with all its trappings would be a sign of intellectual or emotional disturbance. Seemingly not.

The problem is that your hypothesis "this is caused by (bigoted) society" is unambiguously contradicted by the facts, aka "wrong".

In more gender equal societies, men and women self-segregate into different jobs more, not less.
Solution architect here. Having to grok some new tech quickly and put it to use ASAP is almost a weekly occurrence.

The most important thing (to me) when learning a new technology is learning what it _can do_ in the most complete way possible. Reason: when I invest into learning a technology, afterwards I want to be able to quickly pick the feature that is most suitable for a particular need without the risk to reinvent some kind of wheel in a dumb and costly way. And for that I must have a mental map of all the features, at least superficially. Everything else you an look up. (The same principle goes for the total of all the technologies I have learnt before).

In practice I make sure I scan _all_ the documentation for the product and build a cheat sheet of the features, concepts, configuration flags, best practices etc. I will consult the sheet later, but the process of building it helps immensely to construct the map of _what's possible_ with this thing.

A recent example - I had to design a GCP solution while not having much experience in GCP. I sat down and browsed the introductory docs of all the hundred plus (?) products that GCP offers, and built a cheat sheet categorizing the features and intents of each and every one. This took me around two days, and ultimately of in the solution I only used a handful services out of the hundred. But these were exactly the ones that solved the problem, including a couple of exotic ones that I wouldn't have guessed even existed.

For the cheat sheets I use Obsidian which is excellent for this.
The most common heater of an industrial engine is for the jacket water. Keeping the entire block heat soaked is the easiest/safest way to heat the oil as well. Using a "prelube pump", which is a low pressure, low volume circulation pump that parallels the main engine driven pump, oil is continuously sent throughout the internal passages

What you need to know about Wi-Fi 6 (IEEE 802.11ax)
Your (and liberalism in general) inability to understand humor when it comes from someone you dislike is quite concerning.

I recently watched a socialist YouTuber argue against Ayn Rand because someone might read her books and fail to understand it was fiction. And thus her books should be banned. That’s an argument against all fiction books but he made this argument with a totally straight face while speaking against the dangers of capitalism in general.
Yup. It is really bad.

Where I live, the channels 36-48 - which is really just one channel once you go 80 Mhz - is chock-full of networks and completely unusable. The DFS channels are also complete unusable, because they jump around like crazy due to some noise source (I checked, and there's no radars around). Trying to use them means you see disconnects ten+ times a day.

My router can use channels 149+, which are not DFS and most consumer routers don't use them so that part of the spectrum is clear, but those channels have smaller allowed broadcast power so I get slower speeds. Or I could use 2.4 which works reliably, but is even slower than the low power 5 Ghz channels.

Interesting consequence is that while my ISP started offering gigabit connection, I see no reason to upgrade, since my Wi-Fi is now the limiting aspect, unless I start using wires or replace my devices with ones that can do Wi-Fi 6e or something. Even the 300 Mbps I pay for I only get in the living room.
IIUC it's the kernel EDAC subsystem rebooting the server for you. If you turn it off you'll get non-ECC behaviour, but in this case you'll also get really interesting system issues because as the sibling comments have said your RAM is actually faulty :P
My mother used to play Dropzone while I was at school, she got amazingly good at it. A very impressive game for the time, extremely smooth graphics on the Atari 8-bit. I was playing it just a few days ago on an emulator, great game. I've also played Whirlwind snooker as a kid, another impressive game, I didn't realise the same guy was behind both.

Rest in peace
The funny thing about homelessness is that its a material issue. When you address the material root causes, homelessness disappears. So does mental illness, which is why the correlation between these issues and GINI coefficient is so strong.

> Progressive politics in the US sadly transformed from mostly socially and economically-oriented (Wilson, Roosevelt) to an amalgamation of Marxism (Boudin), capitalism, wokeism and social impotency that satisfies no one.

This sentence is incomprehensible. Progressive politics has turned into Marxism and capitalism?
Has it? Capitalism is based on supply and demand, and where those two lines intersect is where the magic happens. Except that we've never adapted it to the reality of, well, computers and the Internet. The price of duplicating a pile of bits, whether it be a Linux ISO, Windows 11, or the latest Disney movie is effectively zero*. Or textbooks to spread human knowledge around. A graph of supply and demand, where supply is a vertical line is broken! Copyright tries to be this end run around this basic fact, when what's really needed is a fundamental rethinking of the entire system.

* Hosting a file < 10 GiB via Cloudflare's zero egress fee R2 and sending across the Internet, once for every human costs approximately $3k - https://www.wolframalpha.com/input?i=number+of+humans+alive+....

Distribution costs via Bittorrent are even cheaper! I don't actually how much it costs to run a DHT node, or even who's paying for them today, but spreading a magnet link around is really close to free!
while I wouldn't wish the bootstrap problem on my worst enemy, I think the idealism helps for at least versioning configuration changes, and partial component-level tear-downs and bring ups (you don't need this often, but when you do, you do).

also, with k8s, nothing like deleting the wrong object or making a change and not knowing what it was, N revisions ago.
While not a movie, I think that’s what made the original BBC[1] run of Black Mirror so eery. Everything was plausible, just a completely predictable extrapolation of current technology.

[1] not 100% it was BBC now that I think about it. Some British channel or another
You got it the other way round. The things you listed are implementation details, the list you quoted consists of abstract concepts.
I honestly doubt very much that a reinforcement learning based approach can scale to the breadth of facts that such a model would need to know about. Is there any reason that using a rewards-based approach to cover one set of facts would in any way generalize to a completely different area of expertise (say, rewards for true facts in mathematics generalizing to questions about literary criticism, or new world cultures), or would you have to include (manually curated) rewards for all areas?
At least NVidia did not replace their driver with a less capable one for older cards.

So instead of GL 4.1, AMD opens source does GL 3.3 for older APUs, and good luck trying to get any kind of video decoding acceleration.
You are basing it on military power, of which no doubt China and the US has some crazy claims, but if you just look at ridiculousness Europe's ones are probably the craziest because of colonies.

I’m glad people are researching this and other peculiarities from all angles, I got a lot of dismissive comments in 2021 about an opportunistic pathogen being a culprit for some issues

but the dismissiveness was paradoxical “scientists didn't study that so they must have ruled it out, stop fearmongering”

people didn't like the idea that there could be a parallel infection going around

annoying
Common man, you started your comment well, but you end up just discrediting yourself with your meme text at the end.

This site is for dialogue not flinging shit.
I don't think anyone who has played enough with ChatGPT is championing the notion that ChatGPT itself will replace Google. They are more so steel-manning the argument that Google might not be the best interface for search.
I think there’s degrees of cattleisation, I have in the past deployed crappy vendor software which needs a unique license key for each running instance. We discussed some sort of license service which would allow keys to be checked out when a container is started, but in the end settled on an auto scaling group with 1 instance for each running container with the key in an environment variable.

That got us the comfort of knowing if the host machine died in the night the task would be rescheduled without a bunch of extra engineering to be able to scale arbitrarily when we only needed a couple of instances running.
I used to live near a secondary arrival path to the nearby airport.

Every time the main route was unavailable, due to wind or something I would lose my Wifi because of DFS. That was really fun to debug until I finally figured it out.

Unifi especially may take hours to get the 5GHz network back for some reason.
Solar panel to battery to electrical engine is pretty efficient. We're talking ~80% efficiencies here.

Solar panel to hydrogen you are down to 30-40% right away before you do anything with the hydrogen. You still need to transport it. Once it gets to a fuel cell, you hit maybe 70-80% efficiencies. That's pretty good but these inefficiencies multiply. So, now you are down to 20%. That's a 4x difference. And of course there are losses along the way, etc. So it's more like 10 to 15%. Burning it is worse.
