Yes, obviously, to your second bit -- nobody would try to do those calculations in imperial/customary units.

But most of my usage of units is more of the form "Oh it's 60 degrees out today? Better put on a sweater!" than how "to raise the temperature of a vessel that is 10 foot tall and 4 foot in diameter containing a solution of sodium hydroxide by 40 F."

I, along with most replies, took you to be meaning that for the former usage you would use celsius, which surprised me. Nothing is surprising about the fact that for calculation of this sort you use metric.

Indeed!

The buoy was in for at most a handful of years, and catches a 1-in-1300 year event in that one location?

The first thought on that should not be "what incredible luck!", but "is there something special about this location, or is that 1-in-1300 estimate off?".

Ask HN: Is TypeScript worth it?
I have been using TypeScript for a few years now, and I haven't yet been convinced that I would choose to use it if I had the choice; not just for my own personal projects but for large scale applications where the codebase is shared with many developers.

I want to skip over the static typing benefits argument, because I think it is well understood that static typing is a good thing and if we could bless JavaScript with a built-in and robust typing system then I don't think many people would be against that. My issue is with the amount of extra work it places on developers, much of it the "dumb" kind of work which can eat up hours and doesn't deliver all that much value.

i) Like a framework, you are at the whim of TS devs as it gets updated (edited)

For example, a new package you install can require a new TypesScript version. Once installed, you then may need to update your source code. This can place quite a high tax on the developer, where perhaps a 10 minute change becomes hours long.

ii) Libraries are badly documented

Most libraries do not document their types, or have no examples using TypeScript. Some worst offenders: Apollo, Protobufjs. The type definitions exported by these libraries can be large and complex, and the error messages emitted by TypeScript are so long and cryptic the result is often a drawn out process of trial and error along with trawling through source files.

iii) Error messages are hard to follow

Errors are long and don't provide enough detail. They will explain a type mismatch referencing many types you may not have ever seen, and are not documented anywhere. Except for simple errors, many of them are very hard to follow to a remedy.

iv) It requires yet more transpilation

Transpilation takes time, and always adds a burden to developers. I didn't mind so much with ES6 etc because eventually many functions were included in a broad set of browsers. There doesn't seem to be much progress including TypeScript in a browser, and feels like these complicated transpilation steps could be with us for a long time.

I could probably add more to this list, but my point is that I just can't see that TypeScript is worth all this time investment and making progress so slow sometimes. Are there others that come to this conclusion? I mainly see positive posts about TypeScript.

edit: I referred to TypeScript as a framework which it isn't. However it feels similar to me in that you are at the whim of TypeScript developers and how they decide to progress with the language.

Exactly, I get that they initially used Ruby given the whole company is build on it. But overhauling the CLI and NOT going for a single binary is beyond me.
But that's at odds with the job description of Senior Engineer? They're supposed to be leading, showing the team better solutions, working smarter not harder etc.

The idea that they should pretend to be an ordinary engineer is strange to me.

Personal itches? The idea was, their solution was objectively better. Not a personal itch. Defensible as better for the product. Just trickier to explain or support.

You reprimand a senior engineer, you'll have no senior engineers. Just a job shop with a pile of undesigned code, boilerplate from the example book that is even more fragile, unscalable, a hundred other problems that have technical debt of their own.

Code is a sophisticated topic. To blame folks who get that and can work with it, is misplaced criticism.
> There were attempts to create tsunamis with nukes. But I’m not sure how effective this sort of thing would be against a carrier.

Not very effective.

Tsunami waves move huge volumes of water, but in the open ocean they are also very long waves. Their travel speed is about the same as the "linear long wave speed", or about sqrt(g*D) where D is the depth of the water.

As these waves approach the shore, however, the ocean becomes more shallow. Waves slow down. The tsunami effectively "piles up" on itself, and a wave that was a little high and a lot long becomes a wave that's a lot high and a little long.

A carrier operating away from shore would see the tsunami in its more benign state. Coastal cities, however, would be in trouble.
In the end you get never around getting some parts of a system bulletproof and reliable. The question is just how big those parts are.
If gas is setting the price as the most expensive form of energy, then it acts as an incentive to build cheaper forms of energy because your margins are that much higher.

Alas, England doesn't allow on-shore wind power, and there's not sufficient capacity (in terms of HVDC lines) to transfer enough power from Scotland down to England to move all of the excess energy.
One more thing that can be used for soaking up rarely generated free energy are cheap old inefficient Bitcoin miners.

There are many places already using it for this. Bringing Bitcoin miners to a place at this point is just shipping a container.

Something that I try to remind friends of when discussing mass extinctions: Extinctions don't happen overnight. They happen in the blink of an eye when thinking in geological time, but on the scale of a human lifespan they're not overnight.

Many folks think of the Cretaceous–Paleogene extinction event (the dinosaurs 65-66 mya) as this shocking cataclysmic event where a comet hit the earth and the dinosaurs were blown away in a nuclear-blast like shock-wave. At 11:59am dinosaurs where there and by 12:00pm they were gone! poof - like that!

While that was obviously true for some individuals in the immediate blast area, most other species around the globe probably took days, months, years, or even more to fully disappear at a species level. They weren't blown to bits in a nuclear fireball, but died over time as ecosystems and food-chains collapsed due to climate change. That's what we're experiencing now.

I also have F-Droid and Termux installed, but to say this offers a complete or optimal Android experience is false.

I don't know that I agree. I think it's gotten significantly worse under the VC/PE monstrosity that has grown over the last decade. The dishonesty has been ratcheted up and there are more Shkreli's, Bankman-Fried's and Holmes's dominating the conversation.
No, all the problems wouldn't go away. But a healthy-weight population would cost roughly 64% less to treat, which implies a 64% reduced hospital congestion and workload. This could get offset somewhat as people die later in life of "old age" rather than chronic conditions or CVD events, but those costs would be much lower. So let's say a 50% reduction over the long run.

Yes, I am a former fatty who has kept it off for well over a decade now. It's really quite trivial to do.
Zerotier really doesn't fail any points, it's just no longer the "hot new thing" or an up and comming startup.

I moved from Zerotier to Tailscale mainly for the fit and finish and Wireguard. Zerotier accomplished everything I wanted for my home network but was never "pretty." Tailscale is "pretty" and easy to use. MagicDNS makes accessing my devices easy as I don't have to set up my own DNS entries.

I moved our entire company off of OpenVPN and AWS VPN to Tailscale. It may not be as cheap anymore, but their networking ACLs and integration with Google/Microsoft for login have made it SO EASY to onboard new people and hardware.

> managed automatically by scope

That’s just an implementation detail. The point is that the object’s lifetime is only known at runtime and will be reclaimed when a counter reaches zero, this is reference counting. Whether you have to manually inc/dec that counter, or the language does it for you through some abstraction is besides the point, it is automatic memory management either way, as it.. manages memory automatically.

> Like what? I can only think of one, which is passing memory allocated in one thread to another thread

Any programming language, both parsing into an AST, AST manipulations, interpretation (and that is a very wide category, not only for things you would think of as proper languages). But even some games may want to use GC for some in-game objects, as the lifetime of those is fundamentally dependent on user action.

Would the litany of managed languages and their widespread usage be less anecdotal?
I know quite a bit about most of the things discussed in the article from having worked for a renewables company and yet I learned quite some new bits I didn’t know about, for example the intra-UK submarine HVDC connectors (and their eye watering cost).

ChatGPT has some interesting thoughts on the subject:

The argument that the end of the high school essay is a good thing is misguided. While there may be some challenges associated with the traditional essay format, such as difficulty in giving useful feedback and a lack of emphasis on deep thinking, banning the use of GPT-3 and other technology is not the solution. Instead, we should use this opportunity to find a better way forward.

First, we should acknowledge that the traditional essay format does have limitations, such as the difficulty in providing useful feedback and the emphasis on superficial elements such as typing and sentence structure over deep thinking. However, these limitations do not negate the value of the essay as a tool for developing critical thinking and writing skills.

Instead of banning GPT-3 and other technology, we should explore ways to use them to enhance the essay-writing process. For example, GPT-3 could be used as a tool for providing feedback and helping students improve their writing. Additionally, we should focus on finding ways to provide more meaningful and effective feedback to students, rather than relying on superficial metrics.

Furthermore, we should also consider the reasons why essays are assigned in the first place, and ensure that the assignments are aligned with these goals. Essays are not assigned to simply prove that students can read and write, but to encourage deep thinking, questioning the status quo, and the ability to develop and express persuasive arguments.

In conclusion, the end of the high school essay is not a good thing, but rather an opportunity to find a better way forward. We should not ban GPT-3 and other technology, but rather use them to enhance the essay-writing process and focus on providing more meaningful and effective feedback to students, while also aligning essay assignments with the goals of developing critical thinking and writing skills.
Frankly because in many (not all) places (and especially true the further back you go) -- there's very few good ... anything. When I first moved to Austin TX in 99 I remember being really puzzled by how bad all the food was. Like nearly everything was mediocre. Very slowly better places popped up and everyone talked about them. The one exception was BBQ, and to that end yes -- the "best" was Franklins but frankly it was nearly all very good.

But overtime, other good stuff started to pop up, and eventually there were enough good places that "the best" became less interesting. Still, Austin is far away from NYC, and of the few times I visited Europe (Italy specifically) nearly everywhere in the US is a bit behind. IMHO that's largely b/c of how new everything is. Overtime as areas become more established, things get passed down and around, the quality of everything goes up. And in some places, there's so much good stuff that yeah it makes no sense to talk about best anymore. But for many places the difference between the best and the rest is the decision point of "is it worth going at all?".

The address Carl Sagan made in 1985 is well worth watching for those who remember those times and especially for those who weren't alive back then [0]

People knew about this before you were born and decided their best interests were more important and they acted in wilful disregard for your life and the lives of everyone on this planet. They weren't ignorant. No facts were hidden from them that they could be forgiven for being misinformed. They knew with certainty what the science was revealing and spent money to discredit the science, cut funding to their own researchers, bought politicians, funded PR campaigns, and continued building their fossil fuel empires.

Everything Carl Sagan said in that address has come to pass. It's wild to watch.

As an author, I agree with what you are saying 100%. But I'm not sure that you are disagreeing with the OP. His point--as I understand it--is that you don't get better marks for writing an essay about Jazz that is clear, complete enough not to have gaps, and deep enough to display comprehension versus writing something that is digestible and flows.

In other words, you are being graded on the superficial form of the essay, not the depth and completeness of your thinking. You may have chosen to close the gaps and dig beneath the surface, buta s he says, the system strongly discourages teachers from grading you on your thinking.

Unless the essay was in a music course, how could a teacher know enough about the subject matter to grade you well, except by happy accident that they are also a Jazz afficionado? If an essay asks every student to write about their favourite hobby, which teacher can grade all the essays at that level?

I agree that one of the great values of writing is to force you to think a thing through, but my read of TFA is that unless you are holding yourself to that standard, you need a reader who will hold you to that standard, and a high school teacher is statistically unlikely to be that reader. And therefore, assigning essays in high school for the most part does not help students.

Those students who hold themselves to a higher standard than trying to efficiently acquire high marks will benefit, but the rest will not.
To be fair, Autopilot, which this driver was using, is included with all Teslas at no extra cost. Personally, I find that road trips are significantly less draining with Autopilot engaged. In the same way that moving from basic cruise control to radar cruise control with lane-keep reduced some load, Autopilot takes it a step further. The difference is noticable. Remaining attentive and ready doesn't negate the benefits.
If an software system can generate abstracts, good. Nobody got into research for love of abstract-writing.

It is a tool. Ultimately researchers are responsible for their use of a tool, so they should check the abstract and make sure it is good, but there’s no reason it should be seen as a bad thing.

Well, mostly because the article that's always cited about the number of cameras in London is tabloid bunk, an utter fiction.

The guy that wrote it wanted a suitably shock-horror piece so he went to the main street of a shitty part of London, counted every CCTV camera he could see everywhere including ones inside all the betting shops, off-licences, pawn shops, cheque cashing places, and so on - all lovely totally-not-dodgy businesses I'm sure - and then multiplied up by the total amount of roads in the UK.

If the figures were accurate then every single-track road that's basically just a cow path with tarmac sprayed over it would have a CCTV camera every four car lengths, which is clearly not the case.

The article says we pay three times, curtail wind and then burn gas. Which is bad.

But all the solutions are aimed at reducing the curtailment of wind. Rather than reducing the gas burnt.

If the money saved by building more wind (or solar) and not having to burn gas saves more money then who cares if more wind is "wasted"?

It would be nice to use every last drop, but I dont want to actually spend money to achieve that goal when it could be used to e.g. build yet more wind, and burn even less gas.
I know you mentioned C in your original question, but some of the techniques discussed in low latency presentations at C++ conferences will be broadly applicable. Many are available on line.

The yardstick Vulkan is measured against shouldn't be OpenGL but D3D11 and Metal (even though Metal and Vulkan share a lot of common ideas which have their roots in modern GPU architectures, Metal is a lot more convenient to work with than Vulkan), and D3D10/11 introduced many of those ideas to graphics programmers already (like grouping related render states into immutable state objects).
Assuming a competitive market, the outcome is essentially the same right? If the government builds more than would be economic for a private company they're paying the extra through construction costs/maintenance/financing that they would have been paying to incentivise the extra turbines.

Oh she grew up in Westchester and her brother also went to UPenn.

“ When Charlie Javice, 19, and her brother Elie, 18, were growing up in the tony community of Westchester in upstate New York, their parents urged them to volunteer their time to help the town’s less fortunate.
Throughout their adolescence, they returned to the local soup kitchen, and each year, they saw the same faces.
That was their first lesson in the problem of poverty. “Obviously, there was a broken system if the same people

kept coming back,” said Charlie.
She and her brother are now a sophomore and freshman, respectively, at the Wharton School at the University of Pennsylvania, where they’re tackling poverty from a different direction. They’ve assembled a student-run microfinance platform called PoverUP that aims to break the cycle of poverty through capital, research and education, and social engagement.”
