In the medium and heavy vehicle industry one of the big discussions is on reuse of batteries at economic EOL. The idea is that after maybe 600 charge cycles a vehicle-sized battery will have a lot of life left but will no longer support the range that high-duty-cycle vehicles require. So they can be recycled into grid storage in a way that creates a virtuous cycle.

Battery swapping might even be a good way to jump start such a system since it could produce a flexible system for curve flattening both by charging in off-peak hours while still supporting fixed-installation vehicle packs.

The downside is that this makes battery systems less flexible, since batteries have to be of some fixed physical dimensions. This may not be practical for certain compact vehicles, but could be implemented more easily with straight trucks.
> settled science

There's no such thing as "settled science", that's the nature of science. Not that I agree with the throwaway account at all.
Consumer car batteries charge 20->80% in under a half hour these days, and are warranted for a minimum of 8 years.

30 minutes seems slow until you realize that you hardly ever need to charge the car away from home. I do not miss going to the gas station!

I’d guess the mechanisms needed to swap the battery would be more maintenance than they are worth.

I guess for delivery vans, which drive during peak solar production, doubling the number of batteries so you can charge during the day might make sense.

>Water fluoridation reduces cavities in children, while efficacy in adults is less clear.[9][10] A Cochrane review estimates a reduction in cavities when water fluoridation was used by children who had no access to other sources of fluoride to be 35% in baby teeth and 26% in permanent teeth.[9] However, this was based on older studies which failed to control for numerous variables, such as increasing sugar consumption as well as other dental strategies.[9] Most European countries have experienced substantial declines in tooth decay, though milk and salt fluoridation is widespread in lieu of water fluoridation.[11] Recent studies suggest that water fluoridation, particularly in industrialized nations, may be unnecessary because topical fluorides (such as in toothpaste) are widely used, and caries rates have become low.[3]

Yeah, I used to look down on that kind of things too, and a decade later, I find myself doing those very things.

Yes, I know sort | uniq. I even have a couple Linux shells open on my Windows work system. But I can't for the life of me remember the magic flags, so I'll either paste the list to Emacs and M-x sort-lines + M-x delete-duplicate-lines, or paste it to Excel and do it there, or do something even more cheesy - whatever is least likely to break my flow.

There are tools more or less optimized for any specific job, but the best tool for the job is the one you have handy, and are experienced in using.

I too increasingly often find myself using GPT-4 for random, ad-hoc tasks. They may or may not be better tools out there. I may even have some installed. But none of them beat being able to just describe what you want, paste some data, and get the results out few seconds later.
I agree with both arguments: In my examples it doesn't look natural (and having such a boring box is really a worst-case but serves well to show the effect very clearly), but on the other side it must be seen in context (like others said before). While nature doesn't have "translucent" materials, this soft edge can be interpreted as a transition you can often see in the real world: be it, that a little bit of sand and dust from the ground sticks on the base of the object or just a variation of the ground-height which avoids an unnatural straight line between the two "elements".
It is of course a hack, and it doesn't work perfectly fine when looking so close at the box, but in my eyes it works very well for e.g. the stones. Unfortunately, I wasn't able to overwrite the shader to disable the blending in the game. I'd have loved to show how Deus Ex looks Without this effect.
Congratulations on launching! I’ve often found myself doing these kinds of explanations as an eng manager to other stakeholders, so kudos for identifying a problem and launching a solution.

Good luck!

> Canada and they have large enough wait lists that people are dying in large numbers waiting for medical care.

Googling shows ~2000 Canadians died waiting for surgical care in 2020. Meanwhile in the US:

* Millions of people delay even starting care in the first place due to costs

* In the seven years from 2000 to 2006 an estimated 162,700 Americans died because of lack of health insurance

* Massively worse medical outcomes than Canada in virtually every metric

* Massively higher costs

* Systemic lying about waitlists and patients to cover up how bad they are [1]

>California has outlawed new diesel truck sales after 2036, and other states aren’t far behind (you can drag the stragglers along).

When the new fuel is cheaper and suitable for consumer's needs, there will be no need to "drag" them along or prohibit choices. I believe this is what the comment was referencing.
I guess the devil's advocate is similar but it's coal to produce the electricity compared to the diesel truck. Thinking both aren't great.

Plenty of eurorack manufacturers use aluminum PCBs as panels - but keep in mind the printing options are super limited at small scale (e.g. 5 colors for the background soldermask, 2 colors for foreground silkscreen). Using an FR4 PCB has the added benefit that if you leave off soldermask in an area the panel is slightly transparent so you can see LEDs thru it (e.g. http://www.makenoisemusic.com/modules/richter-wogglebug)

People with a financial stake in the outcome have decided to invest a lot of money into electric semis despite knowing about all of these limitations (and many more) ahead of time. So they must have some plan for overcoming these hurdles.

Perhaps these limitations aren't as rigid as people swear they are, or maybe shipping modalities change in order to play to the strengths of EVs. For example, there's nothing stopping shipping from becoming a relay-based, rather than point-to-point. Or maybe it becomes financially feasible to have drivers swap trucks. Yeah, that kills the "owner operator" long-haul trucker, but that model is pretty untenable anyway.

Even industry experts can call an idea patently absurd, then have it become dominant over the next 20-30 years. Cable television is a good example of this, it's crazy to attach physical cables to every house in the USA in order to deliver TV, which can be sent over-the-air at a fraction of the cost. But we did just that. The benefits out-weighed the (tremendous) costs.
Seems to me that fuel price volatility is a point in favor of electric, as grid electricity prices are less volatile cyclic price swings (day/night) can be planned for, and grid energy is fed by an array of sources, which reduces volatility compared to being dependent on a single energy source.

Fuel with subsidies and unmet externalities is already a slow-motion disaster...

Cheaper how? Don’t you need a battery change at a certain mileage or age of the vehicle that will eliminate any cost advantage of not using diesel? At least for cars it does. It may be better for trucks considering they do put in a lot of mileage
> But then this program does not halt, since its halting would mean that ZFC can prove that this program halts.

That step is not logically consistent. It could halt, it's just that ZFC can't prove it will ever do so. For example, the program which computes the 8000th busy beaver number halts (per definition of the busy beaver function), but is undecidable in ZFC[1].

An undecidable program can halt. An undecidable program can run forever. But whatever axiom system is being used to decide that can't prove which (without running the program, potentially for an infinite number of steps).

We should, but we don't do enough of that. So let's put efforts where they bring results - even if they'd theoretically bring more results elsewhere, in practice they don't.

In reality we do try to prevent atmosphere pollution from happening, we just don't do enough of it. Some others of us, who're not involved in this process may have better chances with other, less efficient for now but still useful approaches.

Oh and you missed performance at extreme weather/temps.
All of those happen on VPNs period, not just with port forwarding.

Dealing with annoyed law enforcement, hosting providers, and IP reputation is 99% of the value of a VPN. The other 1% is just setting up a VPN server to open proxy everything (which there are scripts on github that can do it in 2mins). Of course its not really preserving privacy much unless there are multiple users...

Any significantly shared connection will have at least one person abusing it and causing most of the problems, the logical conclusion would be to ban the few abusers but if mullvad truely doesn't log/retain billing data as they claim, permanent banning would be difficult as a new account could just be created.

I don't see why they couldn't do some kind of compromise like an account has to be of certain age/spend to use port forwarding. They do keep mappings of ports to account, so its not like they don't know which accounts are abusing. Getting banned would then be more expensive for the abusers.
I used scissors and ended up with a notch in the shape of the letter M. It still worked.
Google doesn't even plan to be running the same OS kernel in a few years, let alone on the same last-gen-security hardware.

> It is easy to shit on the party in office which is BJP right now but show me a country that can have hundreds of languages, all religions and still survive for centuries as one country. Europe couldn't do it. They broke into EU (for better or worse).

I have no idea what you’re referring to here. Europe has never been one country, and will likely never be. Having smaller countries isn’t something bad, nobody would consider multiple Europeans countries to be a failure, or the result of a broken Europe. Even proponents of a United States of Europe (I am one) don’t see having multiple European countries as a failure.
Kind of an odd take. The first folks performing what we now call DevRel were engineers, founders, VPs, and directors. Even now a vast majority of DevRel practitioners are engineers. Which means they do more than one job.

As far as being disrespected or viewed as divas, it's ironically engineers that meme-ify DevRel folks.

As far as the three points, much like every engineer that writes a post about the pointlessness of code tests in the interview process, sometimes things don't change. Granted, those three points haven't been made in "every single devRel blogpost you read since 2012" since the term DevRel was really coined in 2014-ish. but that's not really the issue.

No, there are still many things unresolved in the DevRel industry. It's much bigger than it was, yet "pure engineers" slough it off as meme-worthy and management still can't see past it being marketing or pre-sales. So more people add their voice in an attempt to improve things.

You don't stop saying something needs to be fixed just because it's been said before. You keep saying it until it's fixed.

> Einstein could be convinced to tell you that 7 + 4 = 5

I think Einstein would have laughed at me if I tried to convince him to do that.

Because other than an LLM, Einstein knew what these symbols denote, what their relation to reality is, and how math works. Einstein didn't mimick math by completing sequences of tokens, and relying on humans antropomorphizing the sequence completion engines output to an actual understanding of the topic.

> Ants can't define nuclear weapons, but nuclear weapons exist.

Ants also cannot build nuclear weapons, nor create anything that would make the emergence of nukes any more likely, among other things because they don't have the ability to define them. So if we accept this premise, then the discussion is moot: We can be fairly certain that we are the most technologically capable entities on this world, so unless we can understand a technological creation to the extend that we can bring it about, nothing else will.

In short: If we are ants to the superintelligence, then we have nothing to worry about, because we likely lack the understanding and ability to create it, or even something that could act as its precursor. If we are not ants, then we should be able to predict when this can happen.

> Since we can't accurately predict the future

We can accurately predict a lot of things. Global warming is an example. And the things that we can predict, and determine how likely they are, we can and should prepare for.

AI doomsday preparation demands the exact opposite: That we prepare for something that we cannot predict, and cannot demonstrate if it is possible, or how likely it is. That's like asking to prepare for an ice age. Theoretically an ice age is possible on this planet, however nothing we can see, measure and demonstrate right now, supports the prediction that an ice age is about to destroy us.
It is a fact that we tend to imagine what's the worst that can happen, and as a species it served us well back when we had to survive by escaping from other predators and hunt out own food. Now it doesn't serve us so well anymore, but evolution is a slow process.

> The post compares an Apple 2e, which is a single-tasking OS that just displays the pressed key in the basic interpreter on the screen, and modern devices, where it is not always clear, what kind of app or setup is being used. But we know, that it's plenty of layers of GUI and OS code, that most people don't want to miss. Not to mention, that mot of the higher input lag is not detectable by humans in normal work conditions.

You can do an experiment for yourself along these lines. A few years ago, I pulled out an old laptop that had Gnome 2.x installed as part of an Ubuntu release from circa 2009. In every respect, the hardware from this machine (which itself had been a budget laptop when it was purchased in 2006) was worse than the hardware I was using in my daily life. I was struck (almost startled), however, by the difference in how immediately it responded to my input compared to my daily driver at the time—to the point that it distracted me from the original reason I booted it up in the first place.

A system capable of running Gnome 2.x is no pre-Mac, pre-multitasking system. In fact, it has all the capabilities/affordances that you'd expect and need from systems today. So your characterization is less than kosher (basically a motte-and-bailey).
I've always wondered if the push towards centralization is a reaction to fear of the lack of control.

True decentralization and censorship resistance requires taking the bad with the good. I'm the case of Mastodon, if I can't be censored for sharing my views on technology, politics, or sports then the person wishing to sharing illegal photographs of threats that may be illegal in some jurisdictions can't be censored either.

It raises the very interesting question of whether freedom of speech is an all our nothing concept. Very few people would support the idea of being able to say literally whatever you want, but can you really have freedom of speech at all if someone else gets to draw the bounds with which your speech much stay?

Their estimation was based on Swedish gas prices that, like all European fossil fuels, were artificially maintained very low thanks to staggering subsidies this winter.

Gas price volatility is an argument, but one that they ignored and that will never be in the interest of gas engines. Gas can’t be much cheaper than it is: carbon pricing, restriction on new wells, and instability in the Middle East will only make it more expensive.

Electric engines are measurably simpler. Every estimation I’ve seen is that maintenance for cars is at least an order of magnitude cheaper. I wouldn’t be surprised if e-trucks were more expensive to maintain than e-cars, but all the things that make trucks more tedious than cars (oil, brakes, clutch) are what makes EVs much better. Every specialist who has used an electric truck is very bullish on maintenance.

I definitely agree that the real issue with trucks is their size: current eighteen-wheelers are to big. It’s unsafe; their tires are expensive and need to be changed often. Brakes too, but that’s something EVs fix. The biggest issue is how fast they damage the road.

Lighter trucks would be the best idea. The solution for me is something that Sweden, California already do, but not enough; something that every modern country should do a lot more: carry goods on (electric) freight trains, and use smaller trucks for the last mile.
