I have the feeling that you are talking about european style socket with shallower than normal recess, ie. CEE 7/1. These sockets are sometimes used in Benelux countries for RCD protected circuits without PE, and should only be used for Class II devices which usually have CEE 7/16 “EuroPlug” with isolation sleeves and thus there is nothing to touch. On the other hand nothing prevents you from plugging essentially any other european plug in there which then becomes safety issue both because of the exposed live pins when (un)plugging and missing grounding. Similar sockets were (are?) also used in Russia.

This is probably the only case when CEE-style socket is not designed such that it is safe to use with any CEE-style plug that mechanically fits. In general I view the system as better design than BS 1363, because it solves the relevant safety issuess without overengineering and with reasonable degree of backward compatibility.

I wonder why they didn’t include the RAVPower 61w GaN charger. It is smaller than the “Slim” model and has folding prongs.

You don't have to inject heroin to consume it, FWIW. You're right that intravenous use is probably more addiction prone (not to mention, dangerous for all kinds of reasons).

> people (especially in the USA) seem to think that manufacturing jobs are inherently better than other jobs

I don’t think they’re inherently better, but I do think the person who invents the next big thing will necessarily be a person who knows how to manufacture the current big thing, so the more people we have who know how to do that, the more likely we are to lead the next wave.
Very popular. Even they look small next to a F250 - like you shrunk one down to 3/4 size.
If you found the Khan academy videos too slow paced then my suggestion would be to jump straight into the problem sets. Keep trying to solve things and if you get it wrong then you can get an explanation of the steps in text form. You don’t need to watch the videos at all unless you’re really stuck, and then you can try skipping around the videos instead of watching all the way through.

As I’ve seen written elsewhere on HN: math is not a spectator sport. The best way to learn is to work through problems until you master them. Heck, there are plenty of people in college who never bother going to lectures yet still achieve top grades by putting in the work.

This really is just another poor-me major piece of spin that we Aussies have had to cop in the media in the last decade - following on from these other two gems:
1. too much air-conditioning is overloading the grid;
2. the power bills have been high because they've over-spent on the grid (apparently preparing it for future demand);
3. too much solar is stressing the grid...
Looks like the grid is the weakest link. Time to go off grid perhaps?

1. could be loosely verified - mid-day black-outs were a common occurrence on extremely hot days in Sydney, esp. in the noughties. Or was the grid just not up to it? Lucky they over-spent on it.
2. price gouging is still be rampant, the rates are still as high as ever, and solar feed in tariffs are a joke; If we're swimming in free/cheap electricity, where is the lowering of the rate? and why is green energy still much higher for the consumer? Good reasons I'm sure... probably something along the lines of "the grid can't handle it".

3. Given that we're now (apparently) swimming in all this extra grid-damaging power, maybe it was the solar that really stopped the blackouts - after all, the air-con comes on when the sun shines! Just tell everyone to turn on their air-con. That should solve it!

Good luck to anyone trying to get a clear answer on any of it - like it's been noted, too many vested interests in politics and the media. My view: go-off grid as soon as you can.

On my first internship I worked at a lab and at one point a researcher asked all the staff to be nice enough to read his draft to spot mistakes. I obliged as well, not understanding he meant typos. I asked him about an equation I did not understand in his paper, because I could not link some terms to the rest of the text. He answered that he did just copy it from another paper, that it only made sense in the original publication and that he was not really understanding it either but just enough to know it had to be there.

On another internship I worked for a researcher who bragged about having published almost 10 papers on one of his algorithmic discoveries without ever revealing totally (which allowed him to start a for-profit company with it)

You know, the whole publication + review + reproduction thing really helped science become a more solid process, but we need something more elaborate now. Probably some kind of reputation system that would not just be the number of citations by friends and colleagues.

Their pay is a reflection of the revenue they generate for their publishers, which itself is a reflection of the engagement their content provides for that publisher to monetize through ads, subscriptions or one-off purchases.

Lots of people use ad blockers. The HN crowd is particularly bad about this.

People on HN actively look for ways to get around pay walls. Just to be clear since everyone seems to routinely assume that I'm making a moral argument, I don't use paywalls for my content and I don't have a big problem with people looking for ways around them. I'm just pointing out that they aren't exactly working well for people trying to monetize a thing that involves publishing writing.

People also have a very big problem with writing used as a means to get you to make purchases of some sort, aka content marketing. People are understandably suspicious of writing whose goal is to get you to buy a thing so the writer and publisher can pay their own bills.

I'm glad you have subscriptions. Good for you. But as someone who has put time into developing good writing, gets lots of feedback that I write well and my writing is "valued" but who continues to fail to find some means to adequately monetize my writing, I find all these arguments ridiculous.

I would love to go Get A Real Job like everyone keeps telling me to do. Or even make an app, though I can't manage to get actual coding related questions answered here.*

I've been here over a decade. HN gets over 5 million visitors a month. Between my old handle and this one, I have nearly 50k karma, which presumably is a proxy for "member of the community in good standing whose participation is valued."

And I still can't get what I need, which makes me slightly suspicious that it basically can't be done at all given the state of the world. So, to my mind, saying (essentially) journalists "just need to write better" amounts to victim blaming.

They didn't conquer an empire of millions. They conquered the elites. As best as we can tell, from mexico to parts of south america, they expertly pitted groups of native elites against each other and somehow ended up on top. Nobody really knows how or why they were able to succeed. But even more impressive than the conquest is their staying power. The spanish essentially took over the elites and managed to maintain that position for hundreds of years.

Take mexico for example. After the spaniards positioned themselves atop mexican society 400+ years ago, they never relinquished that position. Even though ethnic spaniards made up anywhere from 1% to 5% of total mexican population thoughout the 400 years. Even more astounding is that the spaniards used their position atop mexican society to outbreed the native population. 66% of current mexican Y chromosomes are of european ancestry, while 90% of mexican mitochondrial dna comes from native ancestry. Fascinating stuff.

The spaniard conquest of central and south america differed markedly from the genocidal conquest of north america which is reflected in the genetic makeup of the populations in the americas.

Did Godel say infinity is the reason too?
Thanks for the response, I don't remember reading about infinity being the reason.

Off topic:
Still, you'd run out of matter in the universe (that you could use for ink), before you wrote down a finite amount of numbers while ever reaching a percentage of infinity. That's how unreal infinity is in my mind.

I know the concept of infinity is useful in math, and in this incompleteness theorem, it seems like infinity is the very reason not all truths are provable. But I thought Godel's incompleteness theorem would apply to physical reality, but since infinity doesn't exist in physical reality, I'm not sure the incompleteness theorem would apply to physical reality. Hmmm

Also, didn't Godel show his theorem to be informally true by stating, "This sentence is inprovably true."? There was no infinity invoked in that sentence.

Same with a lot of the famous, longer lived brands. Seems to tie in with the brand rather than the product becoming the important thing. Quality craters. Often the product(s) that build the brand in the first place, e.g. Craghoppers Kiwi outdoor trousers, been around since before me, but the quality seems to decline every couple of years. Now the only ones worth buying now are old ones on eBay and are unrecognisable compared to the ones sold in the 70s and 80s. The once cheap copies are now often better. Loads of other examples.

Terminal support is the only reason I use Emacs. Remote editing is a must. Emacs is the most feature-complete editor available on terminals.

The alternatives are: run VNC or RDP to get a remote graphical environment for an IDE or use VS Code's proprietary remote extension. Neither of these get me excited for many reasons.

The trick for terminal Emacs is to run Emacs as a daemon and spawn Emacs with the `emacsclient` command.

alias e='emacsclient -nw -a "" -c "$@"'

You will have to rebind some of the key chords that terminal emulators refuse to pass through, but you really shouldn't be using key chords anyway (to avoid RSI).

I'm not so sure that it is hustling, though I'm sure that exists. I'm a firm believer of Hanlon's Razor [0], and we shouldn't rush to attribute malice.

I do think there is a problem that our breadth of knowledge, as humans, is far larger than what one person can understand. There's famous examples of revolutions in science being claimed as mundane results. Topologists said Nash was just applying topology to economics and it was nothing new (to them). Mathematicians saw Einstein's results as unsurprising because of the tensor analysis. (Some of these are over exaggerated and there's definitely a post hoc superiority complex in play). But if we just take this at face value, is any of this bad? I would argue no, because it still takes someone to connect the dots between fields and push studies to think in those ways.

But one thing is for sure, as we gain more knowledge it is more likely that someone else independently discovers something that was already discovered. It is also more likely that some of these are rediscoveries of ideas that were not useful at the time.

I think there is a way to solve this though, but I'm not sure we can (yet). We need some good way to check research in a cross-disciplinary manner. Not only that, but in a highly technical way.

I had this experience with multi-objective evolutionary algorithms. I worked with a researcher who was hung up on the idea of "rotationally invariant search operators." This idea made little sense in the first place. To the extent that it meant anything at all, the properties he ascribed to the search operators were more or less the opposite of their actual behavior.
Totally agree. To make file system crash-proof you really need an ACID compatible underlying storage layer or implement it inside the file system itself. In fact, file system and database are quite similar in case of atomicity and consistency. If an embedded ACID component is too heavy, utilizing a reliable database as storage, for example sqlite, might be a good idea. That’s exactly what I did in ZboxFS (https://github.com/zboxfs/zbox) which can use sqlite as a underlying storage to achieve ACID compatible behaviours.

As a result, lots of recent work is being done in the algebraic setting (rather than analytic), where the foundations are on much firmer footing.

Being algebraic symplectic is a much stronger condition than analytic symplectic, but is still interesting enough (and, for geometry related to linear algebra problems, as is often relevant in CS, is not a very strong restriction at all.)

> If you insist on no errors on master ever you will kill throughput.

There are a large number of automated tools which will help you prevent merging code that could break master: https://github.com/chdsbd/kodiak#prior-art--alternatives. The basic approach is to make a new branch from master, apply one or more commits on top of that branch, run the tests, and if tests pass, merge those commits (with fast-forward) back onto master. This makes it very difficult to get broken commits on master, as they have to pass the tests before. It is possible if you have a flaky test suite, but in my experience it happens very rarely, and is usually very easy to fix if something creeps in. In my experience, they speed up throughput, not slow it down, especially when you account for the disruption that merging broken code to master can be.

> You know, the whole publication + review + reproduction thing really helped science become a more solid process,

I think the model is still good. The examples you stated really do fail at the reproduction part. I think one of the difficulties here is that reproduction is difficult and costly, and there is no one willing to pay for it. A common metric for a paper is "can a smart PhD student replicate the experiment from the contents of the paper?" How many advisors ask their students to replicate a paper? How many students can?

My point was that using an inflation calculator defers to someone's idea of what a basket was, and that may obscure the lack of data, so it might be better to study a few different things that people used both then and now and come up with your own reference point.

I'm not saying there's any alternative, ultimately, to the concept of an average consumption basket, just that methods of determining it might be different. When you have really limited data, you can look at it more closely, and you probably need to, to leverage the context because it's not going to be an unbiased sample.
I'm a vim user, and the most attractive thing about emacs is that I don't have to write vs. I mean it really is that bad. Plus you have org mode, ivy, company, magit, and flycheck. There's plenty to be jealous about. Although you should be jealous that we have ALE and modal editing is far superior to the emacs defaults.
In my view many if not most professors are "careerists" in the sense that they put advancement of their career over accuracy. I wouldn't quite say that you need to be really smart to make progress in most fields, though being smart helps. If you can do a lot of work often you can get a great result without being a supergenius. Ultimately it's much easier to fool reviewers than to do good research.

I think most researchers are somewhat innocent in the sense that they produce bad research without knowing it's bad. Many of these folks seem apathetic to the quality of research, as you found in the professor who said they don't have time to go through the literature. As far as I'm concerned, if you don't have time to go through the literature (at a reasonable level, i.e., more than is typical now), you don't have time to do research at all.
I've used awk for one year of Advent of Code: https://github.com/bewuethr/advent-of-code/tree/master/2016
