I read it as 31kg of hydrogen. You probably need quite a bit of steel around that and a fuel cell.
Can you really forecast inflation? They failed to do so before the whole Russia shit-storm, and they're trying to yet again.

It seems to make more sense to base economic policy on finding choke points and vulnerabilities, and addressing them before they get triggered. Wars from without are unpredictable, but you can prepare for the disruption from within. Economic forecasts by contrast seem like soothsaying.
I think the Lightning Network will be useful for this role someday. The only proof of work that ever needs to be necessarily run are on the Bitcoin network, and you can transfer Bitcoin or satoshis or fractions of a satoshi as the representative of work, instead of the doing the work directly.
Wrong. Only the market that exploits labour. For example, I just finished reading the article about WeldingDroid in Norway:

https://www.linkedin.com/pulse/denmarks-weldingdroid-automat... : Denmark's WeldingDroid to automate welding of tanks used in food production in Norway

Citing profits to continue exploiting cheap labour in lieu of installing new technology doesn’t happen everywhere.

Slavery in plantations was profitable. Nobody can justify it today. And yet there are supporters of minimum wage and dangerous jobs just because it’s not institutionalized slavery.

This here is the key: [..]Faced with rising wage costs and increasing prices of both raw materials and freight, not to mention a widespread shortage of qualified welders, many manufacturing businesses around the world are experiencing a pressing need to improve their efficiency and profitability. In this situation, giving the qualified welders at a workplace the option to automate low-profit operations and focus their efforts on more profitable jobs makes a real difference, [..]

Not nearly as much as required to produce batteries.
This is just a no-true-scotsman though. The term “left”, whilst representing an extreme generalization, means just as much (or as little) in the US as it does continental Europe, or any other western democracy.
Right. And I think subsidies are being offered to switch. (I saw an ad outside yesterday promoting this.)
Electric and Hydrogen trucks today struggle because a truck needs a huge amount of energy to go somewhere.

If that energy could be reduced, the problem would be far easier.

Here is a free idea for anyone working on this problem:

Make it more aerodynamic. EU trucks today have flat fronts and flat back. They're super aero-inefficient. US is better but not much. The flat front and back are primarily to meet maximum length regulations, which are to allow them to navigate small streets. Bypass all this by having an inflatable front and back that auto-inflate to make a pointed front and back when going over 40 mph on a straight road. Use the same kind of construction as a SUP-paddleboard - ie. 15 psi air and thousands of cords for shape. When the truck slows down, have the whole lot deflate to leave a flat front/back.

This will ~halve energy requirements for long distance trucking, which, considering fuel/energy is ~30% of the cost of shipping goods, is a massive financial win, as well as being good for the environment!

The main barriers will be regulatory. You'll have to persuade lots of government agencies to let you run trials of such things on the road. Trucks have pretty strict regulations, and you can bet 'stick a massive inflatable on the front' is going to mean you can't meet some of them, so will need exceptions to those regulations. That in turn will mean your truck can only drive in some states or regions, which will reduce its utility.
31kg of H2, the tanks themselves will be much heavier than that.
Their paid one when you go over the limits. Not everything has to be black and white and reduced down to a single, oft repeated catch phrase like that.
H2 is the future. I can't wait for it to take over the world.

>It seems pretty clear to me that in your scenario Texas wouldn't have jurisdiction over anything that happens outside its border.

States enforce laws across state lines all the time, doing so for abortion - now considered a crime - would be no different. Several states, including Texas, have or are attempting to pass laws making it illegal to cross state lines to obtain an abortion. South Carolina is banning websites which describe how to get an abortion. So this affects not only freedom of travel, but freedom of speech.

Of course Gitlab also got rid of the $4 tier last year, making their cheapest price point $19/month/user.

Clarification: He thinks it came out of a US biotech lab. Given who was the US president at the time of the outbreak... I don't exactly believe it, but I wouldn't be terribly surprised if it turned out that Trump outright ordered it as a covert mass destruction attack which then got out of hand. He would be just the kind of "man" who would ignore all the warnings and just do it.

I like to think it was a Show HN, about a remote isolated browser product, but actually I found that spikes in sales came more often after I made some random comment that showed I'm an expert in that tech, not trying to sell something.

That’s not enough. CAN-SPAM is nearly 20-years-old now, it’s not even a GDPR matter. The rule is pretty clear in having to provide an unsubscribe link in every email.

We just need to travel to a solar system with a gas giant from which we can siphon Hydrogen directly, 'duh.

Should be easy, right?
This is a solved problem, why do people persist with stuff repeated in the 1980s?!

There are endless h2 vehicles on the road. Do you think the tanks used, are apt to become brittle, and leak?!

There are h2 refueling stations for said vehicles, all over the place.

Do you think these leak, and become brittle?

And amusingly, your comment is redirecting from the claim that transporting h2 is hard. You are now poking at storage, instead of at transport (which can be done with pipelines, and is done with them).
> over-certainty rife among users of statistics.

Heh. So people noticed.
Master’s. More than one PhD would be…interesting (although the only person I ever met who did was from the UK)
That is the weight of the hydrogen fuel. It does not include the weight of the tank nor the fuel cell so is not comparable to battery weight in a regular EV.

The trucks also have 72kWh worth of batteries in them and it is not clear if a 400km range includes a fully charged battery pack at the start.

Interestingly Hyundais page has slightly different specs for both fuel capacity as well as battery.

The article is being naive in its views of what the institutions of journalism are trying to accomplish. It is obvious that they are not interested in disseminating facts. Wikipedia crushed the entire industry of for-profit journalists in getting reasonably sourced information out to the world. With lower costs and generally better accuracy and less bias. Mostly by accident and because their deep-citation approach is just better than the alternatives. Top 10 global website, and all that.

The level of failure there by the media not copying them goes beyond incompetence, it is clear that there is no interest. None. Not worth a penny. Nothing of interest to the media.

If the article writer wants to play along with the pretend game then sure, the journalists working for the places he lists are just having a little moment of weakness on a path to bettering their practices. No doubt their bosses are staring glumly into their coffee mugs wondering how to get better information out to the patient masses! However the world is going to be a strange place where nothing seems to quite happen the way he expects, if he wants to believe that.

Journalists are creators of new, interesting and original content. That is often somewhat related to things that are factual. But they are not fact distributors.

Batteries aren’t an answer for anything but cars. Honestly even for cars they still aren’t a great answer. They are way too heavy and take up too much space.

There are all sorts of problems to solve with hydrogen, but I think we’re closer to solving those problems than we are to increasing battery density by an order of magnitude.
If you are a current user, it's possible GPDR actually requires them to send you notices of changes to policy and practices (where relevant to GPDR), without an opt-out?

At any rate, it seems good practice to send such notifications. I don't believe you can usually opt out of "business communications" like this.

Now, letsencrypt is a free service, and they may not be as good as they should about identifying who is a current user? If you don't have have certs that haven't expired, and they're still including you in business communications, then perhaps something isn't as targeted as it could be.

How does this solution compare to Dynamic DNS services like DuckDNS? How about overlay networks like Tailscale?

My initial impression is that it solves a similar problem to DuckDNS (“how can I get a static, public IP for a machine on my residential LAN?”) using technology similar to Tailscale (WireGuard tunnels as a service).

Perhaps egress/public routing is the big advantage over Tailscale? Tailscale focuses on creating a trusted perimeter so all your devices can talk to each other securely. It doesn’t have an external gateway for other people to access specific devices within that perimeter. I think their business model / architecture may actually preclude this feature… they use their hosted service primarily for peer discovery, most traffic is routed P2P.
Everything outside of encrypted datasets’ data is not encrypted. This includes the things you mention as well as vdev labels, block pointers, etc. The clear text bits can tell you a fair amount about the relative age of written data and how much data is present. It will also identify which machine last imported the pool.
Cost matters a lot more than efficiency. The two are related, but not the same. The correct question to ask is how much does a kWh of hydrogen cost, and how much lower can we get that.

That does not sound practical nor necessary. An authentication should be required to disable a service, but is never necessary to stop notifications.

In my view there’s only one thing to do when emails don’t contain an unsubscribe link: report spam — because it is, as described by CAN-SPAM.
>to people who explicitly say they don't know how to write code and spend the entire 45 minutes in an awkward struggle session

If it's important to you to find people who can write code, why are you even interviewing people who "explicitly say they don't know how to write code"? And if you interview them, why are you interviewing them in the same way as people who can write code? And if you interview them, why are you keeping them for 45 minutes on the struggle bus instead of interviewing in a manner they might actually succeed in?
Outlaw as the author calls them “groomed lawns”. They’re a waste of time, energy and resources that could all be going towards something productive.
The hydrogen is produced by cracking H2 out of oil. The H2 is then liquified using electricity made mostly by burning carbon. The liquified H2 is then transported on diesel trucks. Don’t fall for this carbon energy fake out.
Make physical fitness a key component of the educational system, as it once was.

I think the same every time I see reddit posts here. I come here to escape the constant reposts, fake and low quality posts, 0 value comments on Reddit. And then some users decide it's time to make HN into a reddit repost archive. As for the actual post, it sounds super fake to me, and I really hope it is.
Really? Here's a link to the actual report https://www.bankofengland.co.uk/monetary-policy-summary-and-...

>Inflationary pressures in the United Kingdom and the rest of Europe have intensified significantly since the May Monetary Policy Report and the MPC’s previous meeting. That largely reflects a near doubling in wholesale gas prices since May, owing to Russia’s restriction of gas supplies to Europe and the risk of further curbs.

Can you clarify? Currently have a Chevy Bolt and it is great...
Similarly: cyclops -> cyclopodes
The main reason is that both EVs and ICE vehicles have complex supply chains that are currently being disrupted. It isn't like ICE vehicle's supply chains can't be disrupted like an EV supply chain, it is just disrupted by different things.

I ordered a Ford Maverick Hybrid last year in October. Things that have been constraining items for Ford in that last year:
Spray in Bed Liner

Co-Pilot 360 (Blind spot monitoring and such which is on both regular gas vehicles and hybrids)

Luxury Package (Again available across both gas and hybrid, I believe because of heated seats)

Tonneau Cover (Again available across both gas and hybrid)

Mud Flaps

Overall EVs are mostly new vehicles, new vehicles tend to require new parts so the supply chains are younger and less robust. Older EVs such as the Chevy Bolt seem to be available right now.
Seconded, it didn't work well in the beginning but lately it's been solid, and super fast.
How will this impact braking distance?
And how long is the lifetime?

A battery lasts for many years. H2 is used more or less immediately.
Not just dirty but also relatively finite (on earth). Hydrogen is generally manufactured from fossil fuels.
We didn't look into a dataflow engine specifically, in part because we have a heterogeneous set of workfloads. Our core use case is loading mission critical data in chunks, but it is also coordinating SaaS tools and managed services like Sagemaker. So the sort of "just run this arbitrary code" reliably and scalably is an important role in our case, not just the dataflow part of things.
Sure but in that case please add energy costs for recycling the batteries bs recycling tanks for hydrogen. And I do not see how batteries can win in this race.
Just about everything is predicted by someone at some point. Once an event takes place it's very easy to look back and pick out the people who were right.

But ignoring this, allows the anti-h2 crowd to continue to deride h2 tech.

The heart of this often claims that h2 is polluting, based upon the fact that currently, we source a lot of h2 from Ng.

Of course this disregards that electricity is often derived from dirty sources too, meaning, all the same arguments should be levied against battery based power sources too.

What we need, is to get non polluting engine/point of use tech out there, asap! And h2 is the only tech which provides the range, due to refueling speed, to replace many applications.

Without end of use clean tech, we have zero hope.

Any environmentalist should be happy, joyful, exuberant with h2.

Sadly, endless division exists.

The Cartwheel Galaxy Is the Webb Telescope’s Latest Cosmic Snapshot
IMHO, the easiest way forward that makes sense from an engineering as well as financial standpoint:
overbuild as much energy capture as possible: solar, wind, nuclear, doesn't matter as long as it is captured at a location where it is cheap and convenient to do so.
Then use power-to-gas tech and get a well behaved hydrocarbon fuel which is easy to transport anywhere in the world, stores energy at a high density in a relatively safe way, and can be used in practically all applications.
And yes the conversion is super inefficient, which is why you need the energy capture to be cheap and to have maybe 300% of needed capacity.
