That's not value creation, that's zero sum.

SOHCs are approaching 100% conversion efficiency, and SOFCs have 60% baseline efficiency, and with practical heat conversion technologies, have closer to 75% efficiency. And they can use hydrocarbon fuels which can open up fuel options to synthetic fuels that have more reasonable mass/volume tradeoffs.
The guy lived in a small town for 20 years, and it’s clear that he was a relatively private person. There’s nothing wrong with being introverted / private / withdrawn etc.

More to the point, when something came up that was meaningful to him, he stepped up and did a lot of work to try and make it happen, and in the end things did get meaningfully better even if not in the exact way the author had hoped.

I think you severely misinterpreted this story.
The mental disease of many anti-intellectuals and conspiracy theorists is the inability or refusal to understand scale and proportion; it's the single source of an enormous amount of flawed logic.

Scale and proportion is the reason. 7 per 1,000,000 risk of blood clotting if you are a woman between 18-49 (and basically no risk if you're a man or outside that range, or use one of the vaccines that have not shown this risk). This is on the level of shark attacks and getting hit by lightning. Actually getting COVID has more serious risks and a much higher rate of being affected by them.

We regularly ask of citizens to do things that have a 7 per 1,000,000 risk of injury; it's a reasonable ask.

OTOH, using the model 3 as an example, you have to drive around 480kg of batteries all the time, while the same energy (75kWh/270MJ) in hydrogen would only amount to less than 2 kg.

90% of hydrogen worldwide is made using carbon sources. First de-carbonate that before talking about "clean energy".

Most of the trucks nowadays can be replaced with trains. Let's focus on that first.

This it not an engineering issue, it's a political and organizational issue.
AWS is a bad service because they don't let the customer set billing limits.

It seems earning money from users' mistakes is part of their business model.

Yes, resource limits are not a silver bullet. Users will complain when their important service goes down because it would have gone slightly over budget during "normal" use.
Implementing it in a reasonable way is not perfectly simple. Probably you want separate limits for network, storage, and processing as well as different ways to enforce the limit. Deleting all S3 data might not be what many users would want. They might still be willing to pay for keeping the existing data.

And obviously changing the limit must not be possible with the same credentials that allow you to use resources. Another fundamental challenge.

But with the size of AWS's business there is no excuse not to implement anything. They just value profit over customers.

(Sorry, not a reply to the original poster's question. I don't have anything significantly different from what has been mentioned by others.)

I guess it is about that simple if you'd be satisfied with the release of a documentation-free binary blob of weights. Somehow I suspect others might complain about usability.
That would be true for cars, not so much for trucks. Most trucks hit their mass limits long before they hit their volume limits. Most box trucks, for example, are transporting more air by volume than cargo.

That doesn’t preclude learning from younger langages in any way.

The trend of providing really helpful and valuable error messages (especially compilation) really started with Evan’s “compilers as assistants” and “compiler errors for humans” from 2015, although there had been forays into improvements to e.g. error localisation from clang.

And Rust’s improvements absolutely come from there, as acknowledged by Jonathan Turner’s 2016 “shape of errors to come”: https://blog.rust-lang.org/2016/08/10/Shape-of-errors-to-com... as well as his “new error format” proposal / rfc which eventually lead to the change: https://github.com/jonathandturner/rust_proposals/blob/maste...

FAA rejects payload review for Momentus
Yes, but that's not the e2e efficiency of the hydrogen powertrain, a 120kW hydrogen stack found in Hyundai Nexo is as big as an average petrol engine and its energy efficiency is somewhere around 45%, so it's not only the hydrogen tanks and the hydrogen inside it. If we're going to analyze the volumetric and mass efficiency and compare it to a BEV, then we need to take everything into the account.

Majority of hydrogen produced is made from processing oil, the energy efficiency of "green" hydrogen (electrolysis) is very poor and thus expensive.

I believe there's a strong chance of using hydrogen for long haul type of transportation, however, there are a lot of misconceptions about the technology and its general practicality.
This is also one of the benefits of diesel, it doesn't ignite so easily.
Simple, and lightweight sound great in theory but some problems are complex enough they they require a lot logic, and that complexity needs to live somewhere, whether it’s your code base or a dependency. Node.JS could provide its libraries in a modular way so that you only install what you need. Essentially, that’s how npm works now except that the packages are provided by random people, and often times the work of getting them to work together to form a complete solution to a problem is left as an exercise to the reader.

When everything is broken down to very simple packages, you often end up in a situation where your dependency tree is very deep and now keeping track of which packages you use and vetting them becomes a complex task. Many devs are too trusting of the packages they take a dependency on. Remember that npm package that everyone used but was buried like 3 levels deep in people’s dependency trees, and then maintainer got tired of working on it so he handed it over to someone else who then purposefully injected a vulnerability into it which affected a lot of projects?

> If you don’t like it, don’t use it

Again, simpler said than done. My guess is most of us are working on projects where we don’t/didn’t get to choose the tech stack.
Agreed - the real mark of leadership (whether heroic or mundane) is when you're pushing to the next cliff's next handhold, not coddling the lowest common denominator.

has a good infographic showing overall efficiency.

And this text:

With battery-powered e-cars, only eight percent of the energy is lost during transport before the electricity is stored in the batteries of the vehicles. When the electrical energy used to drive the electric motor is converted, another 18 percent is lost. This gives the battery-operated electric car an efficiency level of between 70 to 80 percent, depending on the model.

With the hydrogen-powered electric car, the losses are significantly greater: 45 percent of the energy is already lost during the production of hydrogen through electrolysis. Of this remaining 55 percent of the original energy, another 55 percent is lost when hydrogen is converted into electricity in the vehicle. This means that the hydrogen-powered electric car only achieves an efficiency of between 25 to 35 percent, depending on the model.
Hunting is much more than about population control, I mentioned that in my comment when I said "Hunting is similarly important in some places in Africa, providing them an incentive to maintain their local wildlife population."

In poor regions of the world, incentive alignment is important for species conservation and survival. The people are often barely surviving. If there is no incentive to keep endangered species alive and thriving, then they will be killed for bushmeat. Legal, controlled hunting that brings revenue to an area will help such species survive.

About me:

Passionate about building distributed systems. My experience is designing and working with fairly large scale systems. Most experienced with Java/Kotlin/Python and some touches of Go. I'm willing to learn any language/or technology.
The bigger the battery the faster you can charge it. And commercial drivers have to stop for an 8 hour rest every 8 hours of work by law anyway(at least here in UK/EU). Even using the already existing infrastructure and charging at the relatively common 150kW, you're regaining 1.2MWh(!!!!!!) capacity in those 8 hours. That's a lot of energy, about 12 Tesla Model X batteries worth.
My biggest concern about bugs as food is the potential for parasites or infection in the stock.
We already have issues detecting some of those in animals larger than us, I don't want to see what kind of maintenance hell it's going to be when a single box contains like 1000 "disposable" crickets. Bad employees surely won't help (if they can treat chickens and cows worse than objects for no reason, imagine bugs).

I also get this feeling that once the industry really kicks in, corners will be cut, farms will boom and sleazy techniques by owners could end up with something as environmentally damaging as beef, even if for different reasons. There's also the risk of break outs. I'm pretty sure a million bugs escaping at once because of some accident won't be an easy fix.

Sure, I know we already do operations at a similar scale with shrimp farming or so, but for aquatic creatures you can kind of control their environment much better by testing the water and such. Something like crickets need an environment that can't be controlled as easily, and I kinda don't see someone going in there to clean up every day and check for molds or fungi that could come into play (and it'd be easily covered by a cluster of bugs feeding on it with the inspector being none the wiser because it's a literal swarm inside)

I can be entirely wrong of course. In fact I'd rather be mistaken here, don't get me wrong, but I don't think it's a baseless concern, even cows have had problems that spread to humans (and at least in my country it's the reason you can't buy bones for soup anymore, just in case), and now that the market is more open you could end up with contaminated product and that bug flour was delivered to 25 countries and used as cheap additive in 450 different products before anyone noticed.

More than anything I'd like to see what people thinks about this. Is it a baseless concern or is it something that could happen?
I definitely don’t think aggression is a male trait. Aggression generally comes from fear. You lash out because you’re stressed or afraid. Perhaps the word you’re looking for is “brave” or “confident” or something like that.

Speaking to US readers:

The big takeaway here is how municipal politics works. There’s a tiny number of people - largely volunteers - working on the issues that have a huge impact on everyone’s daily life - and how much they deal with a very motivated and angry opposition all day long. The opposition size is never truly known, and the problem is it usually feels enormous and is actually tiny. It is not unusual for big city projects to be shut down literally by the angry screaming of a dozen people.

Lest you think this is just a small town thing, I have first-hand experience working in a local committee when I lived in Houston, and it was basically identical to what this author described.

Care about our national housing shortage? In nearly every city there exists a small angry mob that works to block every development project, and this job tends to be loudest and angriest about middle to low income housing and apartments. If you want that to change, the single best thing you can do is show up to local meetings and say “I support this apartment building.” Even better if you can mobilize a few friends. You would be shocked at how little it takes to have a big influence.
Typo in headline: should be “validate data” instead of “valid data”. Otherwise, looking good!
The Guix way moves more contribution upstream (it's very easy to get your PR accepted) and less people having their own untested "PPAs" everywhere. People have this image that having a private channel is simpler/faster somehow as it skips hoops but in Guix it's just not true (what hoops?). You can submit PR after PR after PR for something only you would ever care about.

The main reason not to is when you want to keep your codebase secret, right? Composible modules are certainly another solution. I don't know what's ultimately best but I think we could perhaps make it easier to pin a specific Guix revision. Perhaps require it. It already runs different versions of itself so often, it's part of the way it should work.

I am one of those slow programmers that writes good code. My manager used to say that any dates I give him, he has to multiply by 2 or 3. However he knows that any code delivered has no bugs whatsoever. I just checked and I had 4 defects found against my code for the entire last year. I completed about 70 features of varying complexity.

Here is the kicker, I completed the most features out of anyone of my team. What happens to them is they finish a feature and within a few sprints they have at least a couple of defects they have to address from their own code. So their feature + defects ends up taking longer than my feature coding speed.

Having said that in 2020 I started to try to devise strategies to iterate faster, mainly because I felt I could optimize my thinking process since I knew that I had mental loops I would get stuck in trying to solve a problem.

Of course this is just my personal experience.

The only way to make electric long haul trucking work out is overhead wires. Trolley buses in some cites do this, (the latest have enough batteries to run for ~5 miles without a wire which is useful for a lot of applications)

Or better yet the freight railroads need to figure out how to serve their customers better. They are already more efficient than existing trucks, and overhead wire locomotives are already on the market. The US has the best freight rail in the world - and they still lose a lot of potential customers because their operations are so customer unfriendly.

It does, but it doesn't seem to be enough in many cases. And it's not as effective as fasting for a few days.

I had to inject insulin for a few weeks recently, then I fasted for a few days and was able to quit Insulin totally. After a fast of about 2 weeks I had blood sugar levels in the lower normal range and you wouldn't know I ever had a problem. Interleaving periods of fasting and a low-carb diet with 16h-8h intermittent fasting I lost about 20 kg in 2 months.

I wonder why no one ever mentions my big problem with solutions other than email: archiving and backup.

Let's play dumb here, back with POP3 if you configured it to leave the messages the server already had a copy. If you use IMAP you can still have a local copy. (I'm not saying these are valid backup strategies, but if all else fails it's still a decentral copy).

But more importantly, importing and exporting to different email clients and hosts (and even different IMAP server) is varying degrees of work, but it is doable EASILY by default. I can't be the only one keeping 15-18 years of email history and regularly referring back and searching for stuff there? (could be 5 more years but I was careless and didn't properly backup and maybe it's still on some medium...)

Even with matrix, the completely open new hip thing I don't see a good archival strategy by anyone except "somehow keeping logs" like on IRC. Maybe DB backups if it's your own instance. Not cool, but at least possible. And don't even get me started on all the other messengers here. Sometimes the backup works (via Android and maybe iOS) but not always and it's surely not open or accessible.

I'm actually not using email for a lot of private communication these days, but mostly because most of my communication to friends isn't really worth saving (except for logs in matrix/irc channels), I've never been a fan of formal emails between friends. But it's perfect to ask a random question to a semi-stranger. Surely beats Twitter DMs by a mile.

Hydrogen fuel cells don't make sense for consumer cars but there are still areas where the higher energy density and quicker refueling times make hydrogen a viable option.

Is syngas/synfuel [1] a viable route? Obviously it would be less efficient to produce than pure hydrogen (anyone know how much energy would be lost in the hydrogen conversion step?) and probably cannot compete with natural hydrocarbons with current tech, electricity prices and carbon taxes. However compared to pure hydrogen it should have a couple of advantages: compact (same energy by volume as current fuels) and can take advantage of current infrastructure. If done right it could probably power both current ICE vehicles as well as future fuel-cell vehicles. Can anyone comment on any major downsides except it not really being economically viable with current tech.

Elon and Tesla have bet the entire farm on batteries. Something tells me he is not the most unbiased source here.

passenger vehicles are a TOTALLY different ballgame than commercial long haul trucking. Even the early Tesla models could beat top of the line sports cars in some performance measures. The thing is the people who buy class 7 & 8 trucks work off an excel spreadsheet. They don't give a shit if the truck can accelerate way faster than a Cummins diesel or that the driver has a way better HUD or user experience than in a Freightliner cab. They certainly don't care very much that the truck is more environmentally friendly. Maybe they'll pay 10% more all else equal but that's not what Tesla or anyone else is able to provide.

They only care about $/mile and unless there is some massive technical breakthrough, batteries ain't beating diesel any time in the near future on that measure.

Notice the Tesla Semi has been delayed for three years now?
