The only benefit Hydrogen had over BEV was refueling time. I think what we've learned in the last few years is that charging at home overnight makes up for the perceived disadvantage BEVs have, and we're seeing rapid improvement in DC fast charging times (18 minutes for the 800v Hyundai Ioniq5 and it's platform cousins, for example) for longer road trips. In fact I just drove 450 miles across california in an EV and the car was always done charging before I could get my kid out of the car for a bathroom break and a quick snack and then back in the car.

So if refueling time isn't as big a deal as it was 5-10 years ago, and will be even less of an issue in another 5-10, Hydrogen starts to look pretty lousy actually. For those who own BEV's, having to stop at some point in your day to go to a fuel station feels archaic. Home charging is a game changer.

Thanks for your comment! I originally finished my PhD in computational neuroscience and have been riding the deep learning wave for the past five years. I listened to the audio Machine Learning Street Talk episode on GFlowNets, and that was my general introduction. It wasn't until I looked at the image of the GFlowNet on your blog post a connection to actually biological plausible architectures became apparent. The individual firing of a neuron can be interpreted as a Poisson process, but with populations of neurons we often would approximate the firing rate of the entire population as a Gaussian distribution. That would be one patch of cortical column, but these populations are linked together to form larger scale functional brain networks. Anyway, thinking about that scale you could imagine the neural activity communicated between these patches of activity as a type of flow from one region to another. I think your paper raises interesting questions about how this inference engine in our brain might be doing some sort of MCMC like sampling and constructing different belief hypothesis.

As a pragmatic manner, I don't regard having the register and/or addressing mode encoded into the opcode as a separate opcode.

Emulating a modern 64 bit processor would be a major chunk of work, but the old 8 bit ones are simple.

Let's just say it was hilarious if you had anything to do with computers - I could totally relate to the story of an intelligent being emerging from the "primordial soup" of dust collected over the years in an old PC.

> The electric grid will not be able to support everyone going electric, so there will need to be a good stopgap

More accurately, we in California decided that "flex alerts", planned blackouts, and closing plants are the right approaches to our energy infrastructure.

I agree that our grid wouldn't support everyone having electric cars, but why do I get the feeling that it could and should?

A relative designed and built a physical product and when through that problem.

According to his experience the hardest requirements were about high voltage and electromagnetic interference (both how your device interferes with others, and how others affect yours). He also had mechanical requirements but that was fairly easy to test himself.

He was able to design his device to not use any high voltage. Basically buy the power supply off the shelf and don't enclose it in your product.

For EMI, it's hard and expensive. Specialized companies will test and certify your device, but this is too expensive. He found a laboratory in a local university for a reasonable price who was able to help design, define some minimum testing to reasonably ensure compliance without breaking the bank, and realize the tests. It was long and a significant budget.

A lot of his BOM are components from China. His conclusion is that you cannot trust in any way their CE marking. Some pass, others don't. They are all marked. You need to test yourself.

For low volume "artisanal" products, it looks like a lot of people just don't perform rigorous (professional) tests, they just test whatever they at home, mark it and hope they never get into trouble.
At a first glance that book completely fails for an undergrad lin alg course, and looks weak in other areas too.

Examples: the words nullity and kernel don't appear, rank of a matrix is not in it, and, well, every topic I can think of for undergrad linear algebra is simply not in the book.

It's equally bad for stats: no mention of many common distributions a student would learn for example.
There seems to be lots of conflicting info out there on "good" fats. I think everyone agrees that monounsaturated fats are relatively good (e.g. olive oil), but there are two camps for saturated vs polyunsaturated. Each thinks the other fat is the root of many health problems. I suspect that different industries are behind the apparent dichotomy rather than science.

Hydrogen is not something that could work, it already does work. Battery EVs make a lot of tradeoffs making them unsuitable for a lot of workloads. Hydrogen solves them and does not need much development to make it useful for consumer vehicles.

You can look at hydrogen almost as a propane replacement as well.

Nuclear to hydrogen is workable and the way I'm imagining it going. There's also options to create hydrocarbons from air using the heat of a reactor.

ah, see, you've applied logic where there is none. Am I really going to open a philosophical debate with myself when I visit a product's webpage? I scrolled through, I saw different scheduling types, some other features. But as a whole, the software's purpose is "make screen brighter or dimmer" and that's something I just don't have big use for.

And on your second point. I also don't have data. But if people crck software that costs $23, maybe they're willing to pay some fraction that isn't $23. Isn't that reasonable? Or in your mind, are there two groups of people: one that will pay anything, and the other that will pay nothing?

I have about 50-100 PB of object storage workloads sitting on top of LVM cache for the past 5 years or so in production. It works extremely well.

Before going into prod, we tested LVM cache, and bcache, and LVM cache worked better for our workloads. Also, the tooling is significantly better than bcache.

One thing I love about LVM cache is if you are already running with LVM, you can add the caching layer on the fly without any downtime.

Regarding the note at the end where the author sees poor performance. I recommend taking a very close look at the SSD model. I've seen enterprise SSDs that perform worse with sync IO than spinning disks. When we buy hardware, we tell our vendors the exact model of SSD they can use. If we haven't qualified the SSD, we don't put it in production.
Thank you for this!!! I use the repl all the time and had no idea I could do this.
The physics of hydrogen powered vehicles just don't make sense. Insane tank sizes at extremely high pressures are needed to get into practical range territory [1]. This is fundamental physics and won't improve over time, as opposed to battery energy density and charging speeds.

It's got nothing to do with limiting wealth.

Bezos doesn't literally have 100 whatever billion. He owns shares which give him certain rights, and a bunch of people have said "we think these things are worth about X".

If there is a fixed (or practically approximately fixed) amount of central bank money, then from a practical perspective you absolutely want to limit the amount of it anyone could have. If someone has it all... the payments system based on it will stop working. Which would be super annoying.

Strange there isn't a page for the Delicate Arch. That's got to be the most iconic arch in Utah. Very interesting project though! I think my favorite is the Rainbow Arch (not bridge). If you click through the links to Sketchfab there are 3D scans of the arches to get a better view than the pictures provide.

Also, I highly recommend seeing the Arches and other landmarks in Southern Utah if you have the chance. Some of my favorite places on this planet.
What about infrastructure changes? We are using cars in a really shitty way currently. We have the technology to allow cars to go extremely fast, why are we limiting them?

For instance, if you could make a highly aerodynamic truck with huge, beefy tires and put it in a tunnel with very little atmospheric drag you could potentially go up to around 300 miles an hour. If you layer the infrastructure with sensors, the car itself doesn't need to be self-driving it simply needs to communicate with the sensors and stay in it's 'track'. No human would be able to drive within such tolorances, but a program can do that quite easily. All this can be done with current technology.

Hydrogen might still represent a superior source of carbon-free fuel. It's more energy dense than batteries, by a long shot. Containment for hydrogen fuel is a challenge, but they scale better at larger volumes.

Definitely, lithium ion batteries make the most sense for sedans. But for cross-country trucks, trains, and maritime shipping hydrogen has greater potential. You're not crossing the pacific on a battery powered cargo-ship.

If you trust Vox to give you insight into Republican voters, then I cannot take you any more seriously than if I cited a Federalist article to tell you why people voted for Biden. My trust for the Guardian is only slightly higher than for Vox, but I find this article at least seems far more balanced: https://www.theguardian.com/us-news/2016/nov/09/why-did-peop...

It includes things like:

* Voters felt Trump was more genuine than Hillary. That's not hard to believe. Trump is raw and real to a fault. Hillary is a corrupt career politician.

* Make America prosperous again. Democrats like to ignore history that shows that conservative presidents bring far more prosperity; leftist presidents destroy prosperity.

* Trump was the best or only conservative option. In general, the best reason to vote for a candidate is simply that the other candidate is worse.

* A reaction to Obama. Thomas Sowell at the time believed Obama was the U.S. worst president ever. While not a historian myself, I am inclined to take the opinion seriously: https://www.youtube.com/watch?v=0UpiNiaak18&list=WL&index=1&...

Any time you say merit-based hiring and quantifiable hiring metrics, you should realize that your best case is that you don’t add any additional bias to an already (racist, sexist, etc) biased system. And any hiring process company that doesn’t address this in their product pitch doesn’t understand the real barriers to equity in hiring today.

Among other things, almost all stories used to have at least a couple hundred comments. Today there are stories on the front page with less than 10.

The last nail in the coffin for me was their utter refusal to remove absolutely abhorrent comments.

>The study also finds that battery and charging advances will obviate the advantage that fuel-cell vehicles are presumed to have in long-haul logistic operations and the road transport of very heavy goods.

Despite this blurb, I still believe the primary use for hydrogen will be in trucking not in cars. Further more, there are times when some turbines in a wind farm are turned off because consumption has met demand. We could keep those going full time and just convert excess to hydrogen.
> We found that the more a firm responded to complaints, the more likely it was to fall in both value and in perceived brand quality.

Could someone with access to the actual paper tell me if they instead meant firms that responded through public strategies versus firms that responded through closed strategies? This sentence implies, rather, that firms that received more complaints fall in value and brand quality (duh).
