Hydrogen storage is definitely not a solved problem. It was a hot funding topic for the US DOE a few years ago, but sufficient energy density and operating pressures are super challenging targets to hit.

Efficiency depends on fuel cell type and operating conditions and such, but I think it’s generally pretty high for the useful life of the catalyst material. (The catalyst is another materials challenge itself, since I think most of the good materials are super expensive like Pt/Pd alloys, and they’re vulnerable to carbon monoxide poisoning)

Edit: this DOE program page has some good detailed discussion of the current status, including on compressed liquid/gas storage systems, which I’m not as familiar with: https://www.energy.gov/eere/fuelcells/hydrogen-storage-curre...
For languages that support async/await (Typescript, C#, Python), you can write code that looks blocking but got executed as if it's a non-blocking state machine.

Mostly nitpicks:

> math formulas created by artists

Rarely do artists create the BSDF, generally a general model BSDF is provided by an engineer or scientest, and the parameterization is tweaked by an artist.

> that specify how light bounces off of objects

Technically a BSDF generalizes all light interaction with medium. a BRDF, is the function that describes how light bounces (reflects, the R in BRDF) off of objects, which is sufficent for raytracing solid, non transparent/translucent
objects.

> And an "uber BSDF" that kind of provides sliders for many different objects. (Invented by Disney

The idea of an uber BSDF wasn't "Invented by Disney" Brent Burley did develop Disney's principled BRDF at Disney, but it builds on a long foundation of uber BRDFs at VFX studios. He did popularize, if not invent the idea of a metalness map. It was however already possible to represent metals in existing uber shaders by just using a standard full color specular lobe.

> Understanding the hardware (SIMD-cores, maybe even GPUs)

I'd add understanding memory cache hierarchies, and their affect on performance highest among those.
The beauty of public markets is that you can make a handsome profit if this is your conviction, you put your money where your mouth is and it turns out to be true.
> there’s reason to believe neither Intel nor AMD could achieve Apple’s efficiency even if they had the same process, ISA, and area to work with.

From what I have seen the only difference in efficiency is the manufacturing process. M1 consumes about as much power per core as a Ryzen core. AMD also has a mobile chip with 8 non heterogeneous cores that has around the same TDP as the M1.
The keys don't just "somehow" leak. They leak because someone has access to your device, where the messages are stored unencrypted anyway.

What does that command do? Does it install dependencies, or simply verify the versions of the installed dependencies?

Is there some explanation why AMD processors are unsuitable in, e.g., the Mac Pro?
> I personally find it far more interesting than the halting problem.

I agree.

Another cool theorem related to the halting problem is the Rice theorem, because it's a really powerful thing to say that every semantic property on programs is either 1. always true 2. always false, or 3. undecidable.

It's an absolutely uncompromising theorem.
There seem to a be a couple of "camps" in HN. Broadly, those who enjoy reading, and those who don't, but endure it as a means to obtain information.

I'm in the former camp, and enjoyed your writeup quite a bit.

The latter camp will reliably show up when writing is any more long-winded than it absolutely must be, and will a) summarize (good) and b) complain (annoying).

It is what it is. Congrats on your whimsical creation!

There are a lot of people who command a lot of money that love to interact with, 'do deals with' important people, it elevates their status, much in the same way North Korea staged the US/N. Korean talks, ensuring the photo op had 'equal numbers of N. Korean flags to US flags' etc..

The developing worlds has vast sums of money controlled by unsavoury figures without a whole lot of oversight there are innumerable ways to 'pretend to do business' or to 'do it poorly enough' that he can bleed small time investors for a fortune.

While 'Bloomberg' and every other bit of financial press literally spells out the disaster of the numbers, how none of it makes sense, he can literally tell his 'investors' that 'the media is out to get him and that they are lying' etc. etc..

He's not incorrect about there being sugar in many things in the US, though. I've had to start reading labels a lot more after moving to the US, since some of the products I've used at home actually do have sugar added in the American version.

For example, this pasta sauce has sugar in the American version (https://www.classico.com/product/00041129077023/italian-saus...) but not the Canadian one (https://www.kraftwhatscooking.ca/brands/classico/product/cla...). The funniest thing about it is that the Canadian version still says "Product of USA" on the jar, they just cut out the sugar for that market.

Some of the local foods in the US also have off the charts levels of sweetness, such as southern sweet tea and sweet potato casserole with marshmallows. Bread and pizzas also tend to be on the sweeter side in the US.
I'm confused, Hashnode seems to be multiple years old? https://news.ycombinator.com/item?id=11018763
I've also never had the issue where process mailboxes were filling faster than the messages were being consumed. If I were to run into a problem where that was an issue I would question whether or not erlang/elixir was the right tool for the task, but in my experience there's always been a way to spread that load across multiple processes so that work is being done concurrently and eventually across multiple nodes if the throughput demands keep increasing. If the workload truly does have to be synchronized I've always had the experience that sending a message to another tool was the right answer - maybe a database query or another service, for example.

Hi there! It’s great to hear you are working hard on your project. You may have missed the essence of the advice you were given, though. You can’t be at “beta” if you haven’t yet engaged with customers. You may be at “alpha”, but you probably have some revisions and decisions to make before you are truly are ready to formally test and verify. To answer your question about pre-marketing, you might consider a landing page with a small demo and place for interested parties to leave an email address. But first, work with 10-20 people on your current prototype and listen to what they say. Then go back, revise, and then get ready for broader testing. I hope you find this helpful, and good luck with the project!
It'll take more than just belief in the government. We'd need people to actually care about making government better.

Most people just show up to vote once every 4 years (or less) and make their decision based on the party affiliation or the wedge issue du jour, and the rest of the time pretty much ignore what's going on or don't have the power to do anything about it, which gives a lot of leeway for special interests to slide things in under the radar.

The new mac mini will be much better than the old mac mini. I have no doubt that for some it will be a game-changer: the ones who will never use anything except a mac but ran into performance limitations with the intel-based models.

But for people who do video editing on ThreadRippers and such, the new Mac Mini is a little, not-too-fat nothingburger of a machine. The fact the the "$4000 iMac Pro" was woefully overpriced and underpowered doesn't change that.

Hint: I can run a faster Mac in a VM on my 16 core threadripper than I could ever have bought from Apple.

The Hunter Biden laptop story was literally the results of a scummy right wing conspiracy with little supporting evidence laundered though the credentials of a mediocre publication in order to attempt to effect the results of the election so as to assist a Mussolini like figure intent on dismantling democracy as we know it.

There is no valid theory of morality which allows one to simply disregard predicable consequences of ones actions in preference for purely theoretical considerations.

This is why many other publications refused to run with this story because merely presenting "both sides" would not in fact be morally neutral it would have been wrong.

In the same vein Sen. Doug Mastriano was not presenting legitimate concerns about election fraud. There isn't any evidence for such it is literally a smokescreen for a desired takeover of the American government by a hostile minority.

The nypost and Mastriano are traitors in the old and simple constitutional sense of conspirators against the legitimate form of government on which all other freedoms hinge. It isn't that they are attacking Biden he like all leaders will be a transitory feature in our system of government here today and gone tomorrow. What they are attacking is a democratic form of government by polluting the essential contest by which we choose our leaders with lies about candidates and lies about the process in order to undermine the whole thing.

The fact that such actions aren't sufficiently clear cut to rise to prosecutable crimes doesn't mean we ought to forget their betrayal. It is OK if twitter doesn't lend its microphone to Mastriano or the nypost. Let them rent their own website if they prefer. Ntd.com is incidentally a laughable source that nobody ought to credit. For gods sake the story you linked is actually them reporting on a story from the epoch times. For the record the real and complete story is that twitter NEVER suspended the senators government account and says that it suspended the personal account because someone reported it for impersonating the senator and it was reinstated.

Presumably a more reliable source would have included the entire story.

Well, this relies on the assumption that a God also inherently exists outside of time and space, which is debatable even among religious scholars.
Except in most places the hospital are not overflowing, even in the event of hospital overflowing, the measure should be to increase capacity, re-distribute to other hospital, don't admit people who only have mild symptoms.

In fact, I would argue that lockdown can cause overflow because of all the delayed procedures and layoffs due to lack of doing those procedures

>No, unfortunately, if you cannot independently verify the claims in the paper, quantity becomes important (obviously, the papers have to com from reputable sources).

A great project for learning a new language: You have a chance to use abstractions to implement your own vectors, etc. You have a chance to unit test your vectors and vector math. Performance is important, and you have a chance to utilize multi-threading for positive effect. There's no complicated external dependencies like drivers, etc; it's just basic input and output streams and some math in between. It's not too big and not too small, a few hundred lines is just right for creativity and experimenting without taking months.

Actually no, NixOS is probably easier to use than other Linuxes. It gets more difficult when you need to package something new that it doesn't have, then you have to know the Nix language and how nixpkgs work.
I found myself in a similar situation with a budgeting app I wrote. Initially I was planning to make it public but the idea of dealing with people's financial data and paying for all the infrastructure caused me to change my mind.

Instead I've been exploring a strange idea of using sqlite client side. People would save their data to a sqlite file that gets downloaded, then when they come back, drag the file back onto the browser to pick up where they left off. A little awkward, but 100% client side, side skirting most of the problems.

(I realize hardly anyone would bother to use this app. But making it public with sqlite is really just an experiment. I host the app on a raspberry pi inside our home network and we use it that way.)

Trevor Milton invited me to his headquarters to prove his trucks weren't fake. While we were having lunch I asked him about the longtime friend of his (15 years, went to his wedding) who he had framed for extortion. The friend later committed suicide when he got out of jail. This was all happening during the Nikola reverse-IPO process.

After a recording of our conversation was posted online, a bunch of women came forward with accusations against Trevor Milton. That and the Hindenburg report are why GM can't do this deal anymore.

They weren't investing anything. They were getting the equity for free essentially, just to let them use the GM hydrogen tech that GM was planning to throw away anyway. So why would GM back out of a deal that was so sweet for them? It was really that bad.

This is what made it such a fun project for me. I don't enjoy really complex math, but I love optimizing and refactoring and making things more modular and achieving new visual effects. So I was able to just drop in a couple of key equations from the internet, and I was off to the races and got many hours of enjoyment from the infinite tail of possible improvements. Plus, you get really satisfying output really early on ("in a weekend"), which is a big motivator for me to keep going.
By that logic I can also says mask cannot be taken seriously on the societal level, unless you are being paranoid.
You feel that way because you realize that it's a calculated attempt to ride the coattails of an infinitely more successful and reputable company, a deliberate confusion, like if you opened a coffee chain named 'Farbucks' (slogan: "We'll make your dollar go further!"), or the small pennystocks which aim for stock tickers deliberately similar to real companies (Matt Levine covers the occasional bumps in the stocks of 'accidentally' similar stock tickers).

I've been following the SF homeless situation pretty closely.

The numbers are that of the $300-350 million/year SF budget for homeless, 60% goes to permanent rent subsidies (low-income long-term residents.)

That leaves $120-140 million/year for actual street homeless of the reported 5,000 people. $30 million/year is given out as $500/month vouchers, leaving $90 million-$110 million unaccounted for (ie. likely social workers and bureaucrats.)

Other cities have reported:

- 100% of street homeless are on substances

- 50% of street homeless are mentally ill

That means 50% could still be treated/rehabilitated/re-employed with inexpensive programs (mailing address, internet access, showers, transitional housing.)

SF has a couple problems though:

- homeless migrate here, so it's really a federal problem

- SF rents are so high that there will be a surging tide of homeless from the city residents post-2020. The lower-middle class individuals really need to emigrate in an orderly fashion beforehand.
I'd be interested in connecting, hearing more about some of the challenges you've had. It is definitely a hard problem.

Intel/AMD could produce an ARM processor that could find a market.

Intel did have an ARM processor line, and it did have a market. They acquired the StrongARM line from Digital Equipment and evolved it into the XScale line. What Intel didn't want was for something to eat into it's x86 market, and Windows/ARM didn't exist. So they evolved ARM in a different direction than Apple later did. It was very successful in the high-performance embedded market.

> I occasionally ask our principle / sr. Python engineers about this, and their response is always, "These things come and go, virtualenv/wrappers + pip + requirements.txt works fine - no need to look at anything else."

At the macro level, this seems like a bit of a self-fulfilling prophecy: if all the senior and principal engineers using Python don't care to take a look at something else, then it's not too surprising that new solutions don't end up sticking around. That isn't too say that there does necessarily need to be a change in the Python community's choice of package manager, but the rationale for not even considering looking at other options doesn't seem super compelling.
