People are often surprised at how encompassing a sufficiently wide stereo setup is. My stereo speakers can go down to 50Hz so I don't consider a subwoofer to be essential. However, with a larger screen and multiple people viewing, a centre speaker is a good improvement. The ghost centre channel on stereo only really works if you're sitting in the sweet spot.
My impression is that BEVs are much easier to improve incrementally on many fronts while hydrogen faces a lot steeper hurdles.

With hydrogen the fuel cell stack, tank, refueling mechanism and distribution are all things you need to solve. With BEVs some of those points collapse into just one component (the battery), we already have a distribution network and at low charging rates any wall plug will do.
The technology baseline for electric cars is so low that they're about as old gasoline ones. The same can't be said about hydrogen.

La matrice dei formati digitali
It's always lack and coordination and power, not lack of will. There might be around a thousand scientists in the world that are relevant enough to be able to contact other big names and try to get the whole scientific community on board, not only with a massive effort to make the problem well known to the general public and try to gather enough attention to it, but also making some specific proposals on how this can be solved, and proposing some rather drastic measures if laws are not changed, like getting scientists to agree to ignore any paper that's not released freely and publicly online, and trying to get the media and everyone else on board. But those big names are usually very busy already, and doing useful things. Not more useful than this, but translating from will to coordination is one of the biggest problems preventing humanity from making the world a better place. Some essays like "meditations on moloch" have discussed this problem in more detail if you are interested, but the key idea is that existing power dynamics and the interests and willingness to cheat or be "cleverer" of a minority can deeply compromise the game for everyone else, moving the individual "rational" decision (low risk) very far away from the collective optimal.

Well, I think this overestimates people outside the HN echochamber again. Most senior ML people we see in big corps have no clue what they are doing: they just fiddle with knobs until it works. They would not be able to explain anything: copy code/model, change parameters and train until convergence, test for overfitting. When automl was coming a bit I hoped they would be fired (as I do not think they are doing useful work) but nope: they have trouble hiring more of them.
> Now it's refining the idea someone has until it's code.

This is one of the most succinct ways I've seen this said. Thank you.

For the most part the days of handing a programmer a spec who then codes it up are gone. For many problems, programming itself is the easy part. Figuring out what to program, and the complete solution is where the majority of the work resides.

>The efficiency compared to battery tech is horrendous.

nope

>Hydrogen is effectively a storage technology -- we have to generate it and compress it. Which combined with the above means that charging a hydrogen car will always be more expensive than putting the same amount of usable energy into a battery powered car.

Nope, 350kw charger -> loss

>Let's not forget that the cheapest way of generating hydrogen is from fossil fuels. Electrolysis is very inefficient.

no, newest one >95%

>Any concern there might exist for the effect on the electrical grid coming battery powered cars multiplies for hydrogen due to the inefficiency.

Nope you get more energy with less area used via pipeline than grid lines

> In the end, a hydrogen car is ultimately electric. What is more convenient, having a car that can be plugged into an outlet, or a car that needs an extremely specialized hydrogen station?

home hydrogen station exist

> IMO the only excitement from hydrogen is for fossil fuel companies, because that's what the vast majority of it is made from, and because it'd be a fairly natural fit into their existing infrastructure.

wrong fossil fuel companies still want to sell fossil fuels. we have to deal with emission inside cities. hydrogen cars cleaning the air while driving. battery cars still emit emissions.

Hydrogen is super hard to store and transport. Electrolyzers are prohibitively expensive, and probably won't be cost competitive until 2050: https://about.bnef.com/blog/liebreich-separating-hype-from-h...

However EV's last mile problem is solved, at least for people with garages. 220v is more than enough for daily charging. A 120v 15amp circuit is almost trickle charging at <5mph, but most car are idle >90% of the time and that slow charging is enough to replenish a typical days driving in 8 hours.

As far as the transmission and distribution grid, shiftable load like car charging has the potential to drastically reduce grid costs, by shaving off peak capacity, and utilizing the times of Los grid usage. Chris Clack is a leading grid modeler, and his latest grid models tor decarbonization show massive savings by putting batteries and solar at electrical meters. Car charging is half of the function of home batteries, and it's likely that in the near future, many cars will allow vehicle to grid discharge, like the new f150 truck.
I have no data here just my personal experience.

In my area (in Norway) there are probably 50% EVs on the road now, closer to Oslo I bet the proportion is higher. In my street alone with 10 houses the cars are about 80% EVs and I just heard another neighbour has ordered an ID.4.

The local bus is also electric and it has a pantograph that draws 450 kW from a charger just 50 meters from my house in it's "down time" as I am at the end of the route.

No problem with the grid so far, but they have put a capacity charge on how much max capacity you use divided into 50 NOK ($5) monthly tiers. The tiers so far are 5, 10 and 15 kW, I'm unusually in the 5-10 bracket since I turned my cars down to 3.4 kW charging. In addition they lower the grid price during night to encourage people to charge when not much else is in use.

But so far it has not required a massive grid build-out. It might be since the grid itself is well maintained being critical infrastructure.

Since we are in the subject of hydrogen cars and pumps, there is also no tax on hydrogen cars here so there have been a few, but not nearly in the number of EVs. The pumps will sometimes require more time to refill than a charge since if you have many filling in a row the pump itself tends to freeze up and requires quite some time to thaw.

The requirements of a hydrogen pump station is far higher than a gas station, it's not just the matter of shipping it on a truck to an existing one. You need compressors and decompressors (why it's freezing up) and it does take quite a bit of energy.

There is also the issue of leaking since hydrogen atoms are so small, we did have one blow up not that far from here a couple years back.

After living with only EVs for over two years now I think it's the way to go for personal cars and buses, but for ships and perhaps aircraft hydrogen makes more sense.

It's also easier to store excess grid power on sunny or windy days using hydrogen, but right now the issue is also that most hydrogen is produced using steam-methane reforming [1] which emits CO2. Way better than petrol though.

He removed money from Uniswap. Uniswap is a decentralized exchange. At the heart of it there is the ability to provide liquidity by funding the exchange wallets.

Imagine Dollar and Apples as our currencies. The exchange rate is 1 to 1 for this example. So in order to provide Uniswap with liquidity you give them 100 dollar and 100 apples. People can trade against those assets, in turn you get a small fee for every trade. If person A comes along and buys 40 Apples, the Uniswap wallet now contains 140 dollar and 60 apples. These still belong to you, as they represent your share in the wallets.

What Techlead did is, he created a coin (like our Apples) and provided Uniswap with his coin and USDC (basically a coin tied to the dollar). This way people could buy his coin. No, after them buying he pulled out money from the wallets, now his shares are predominantly in USDC. By removing the liquidity the pools are now incapable to provide sellers of his coin with USDC, therefor the market is dead.

I think there are a scary amount of programmers (this is their job and they get hired: often they are already seniors) who cannot explain what they copied or even wrote themselves. I have asked guys with 5 years or more job experience why they wrote something they wrote and I get 'because it works'. Sometimes I have trouble seeing why it works and usually it means there are indeed those disastrous edge cases. Copilot will make this worse and has the potential to make it far worse.
Because front-end developers are the least visible to the CEO (the furthest away from the business data).

Backend developers are a little bit closer to the business data than backend developers.

Devops are even closer to the data that the CEO wants.

The "visibility" is not "visibility relative to the product" but "visibility relative to the profit".

If you draw the entire business as a series of concentric circles, with the circles representing the business, the centre of the circle (the heart of the business) is Accounting, the next layer would be HR, the next would be sales, then marketing, then maybe advertising, then product development...

The only people less visible (further away from the business data) than the front-end devs are the data entry people.
I know this article is from bmw but afaik people are interested in hydrogen for other types of vehicles than cars. Ships, for instance. Forklifts. Trains.

Planes will never work well due to hydrogens low energy-to-volume ratio, unfortunately.
I completely agree that hydrogen is fundamentally flawed, but from a commercial point of view it makes sense in the EU where the "Green deal" has allocated upwards of 500 billion euros for establishing a hydrogen economy over the next decade.

At one of previous gigs we had weekly newsletters organized and edited by our VP. Besides org-wide news it typically featured 1-2 freshly written in-depth articles about some piece of our system or project by engineers who worked on it. An archive of these posts served nicely as a repository of knowledge: if you needed to know how some component worked, often there was an article there by experts involved, even if somewhat dated, giving you enough background and pointers to get started. The background stories were especially interesting e.g. giving you some historical context why something exists and was designed this way, which is often missing from other forms of technical documentation.
I prefer containers over pyenv and poetry. This way not only python version and dependencies are "in one place" but also all other stuff that comes along with a new project. The OS, the database etc.

The one thing I dislike about Python projects is that Python plasters the compile cache files all over the place. Is there a reason to change that? Currently I use the -B flag for all my scripts. But that makes it slow. I wish Python would have an option to perform like PHP and keep cached compilations in memory instead on disk. Or at least somewhere in /tmp/.
Where I Can Find Good LinkedIn Data Scraper?
But that is not true. When learning a field, you must first learn the terminology. Then the big picture and general rules of thumb. Then the details and exceptions.

If an article can convey some of the former, you're smarter than before. Not as smart as an expert, of course! But how can one short article turn you into an expert? That is an unreasonable goal. Every summary of a complex topic will contain and gloss over some factual errors.

Take, for example, an article explaining big-O notation and conveying that sorting can't be faster than O(n log n). Now, you, as an expert, say, "Well, that's not true, that only applies to algorithms with pairwise comparison; we can do better if the domain is very restricted and known a priori, etc. etc.". Fair enough. But still better than not having read the article.

In fact, I think that The Economist does exceptionally well on that front. It will introduce a topic to you, outline the major questions/developments/points of contention, summarised from talking to several experts, and then often (quite opinionated) give a verdict.

You should not take it as gospel, obviously, but it would often reflect the consensus of the experts (of a certain school, sure), but also give you enough background and opposing positions that you can do your own research to dive deeper if you so wish.
Where you go wrong here is that a webcam image is pretty stable. Same background, person moving a little.

Sure it can't be as optimal as a non real-time compressor can, and should therefore need more bandwidth, but high compression ratios on such an image aren't difficult. It's not valid to compare professional film work or even output BluRay encodes to what's required for your typical home video call.
Hotz has mentioned that the training code is not public because it wouldn't benefit anyone apart from those that are trying to wholesale copy the entire project. You can see model architecture and gleam insight from the decisions that they made. You can run simulations with the model and replay scenarios. You can add support for currently unsupported vehicles. Dev tools let you see signals generated.

There's a lot of stuff you can do. But what they don't let you do is easily clone the report, throw a few million in compute and repackage what they had built. I think it's a reasonable restriction.
