I guess historically grad school was an apprenticeship for academic research and teaching. I don't think you "need" this kind of skills (working 4+ years on one thing with a very small team) anywhere else.

Nowadays, the excess of graduate students made this _the_ convenient signalling criterion for a lot of jobs (ML at FANG, liberal arts jobs (for which studying makes real sense - think museum curator, school curriculum development)). While this has been around for these kind of jobs for ages, the glut of PhDs, etc. effectively limits access to people being able to finance their PhD and having access to the required signalling from their undergrad. In the US in general and liberal-arts worldwide this effectively means that the aforementioned positions (of a certain power) are only available to the already privileged. If you get a rare living-wage scholarship or happen to live in certain parts of the EU, this can be quite ok though if you want to increase your signalling value and do something off the beaten path.
> No one in their sane mind would retire or give up their faculty position in this environment.

This environment will probably drive some faculty to retire. Distance teaching is a lot more work than in-person teaching, and it's a lot of new skills and fiddly technology. Someone who could retire anytime now, and was planning to retire in the next five years may decide to do it sooner than later.

Although, they may not be immediately replaced, given enrollment/revenue drops.

Do you think that people would continue to work for Uber after the first month if they were really earning $4/hr when they could walk into a fastfood chain and earn minimum wage?

So either your number is wrong, or the answer is yes. Either way, you're not arguing for what you think you are.
I've been using iSH for more than 2 years now, and I'm glad to see that it's made it to the app store.

Here are some good use cases I've used iSH for:

- youtube-dl videos to Files app

- SSH into remote servers

- performing network pings or scans discretely

There's even a device at /dev/location which when catted can keep the app active in the background, due to background app refresh. The only real issue I've had (especially with Python programs) is that it runs orders of magnitude slower than native.

African and South American countries you have in mind have typically highly corrupt police force. Police themselves being often also criminals or cooperating with them is big part of problem. I dont think that is argument for why it is good idea to adopt their tactics.

The murder clearance rates are quite low when I checked, so at least part of issues is the way police prioritize their work. And you wont raise murder clearance rates by surveilling protesters nor by having guns from army nor by arresting people for loitering and what not.

You cant disincentivize homicide when you don't catch murderers. And most murders are also among people who know each other, not random events.

No, you underestimate issues that come with hiring someone from another country.

I am not going to hire an accountant from Vietnam to do my taxes even if I would be able to pay him $1 instead of $100. Accountant from Vietnam is not going to learn US or some EU country tax code if he has customers in Vietnam. In case something goes wrong, like you would have to go to court to settle things, good luck on getting someone from other side of globe to the court and setting things straight.

Local regulations, local language plays huge role in a lot of jobs that can be done remotely. But they will be done 'local' remotely so you still compete locally not globally.
I think this is really neat. It’s seems a bit more flexible than the composition approach of SQLAlchemy, too.

I also like that the unit of composition is the CTE.

I can highly recommend OsmAnd+ for navigation, it's fully customizable to whatever you want it to do (I was rather suprised it had relevant hiking routes available on my last vacation).

Just for research. Most research models are not used for anything. Imagine having to serve a model that requires 2 x 32GB GPU to billions of users.

Text to speech is also much worse in deployment compared to research. The recent research models have much better intonation.

GPT-3 is the worst offender here - it's so big that it becomes almost uneconomical to run, and certainly impossible to offer for free. (estimated requirements are 11 Tesla V100 GPUs)

Ask HN: How do I improve my command of mathematical language?
First of all, sorry if my English sounds off, maybe weird; it's not my first language but I'm striving to improve.

Short story short: I went back to high school in my late 20s and next year I'll graduate. Over the years I went from hating math to really enjoying it, especially calculus, but there's still one thing that keeps bugging me, and that's my command of its language. I have no problem solving most of algebra or calculus problems, but if you asked me to explain what I'm doing I wouldn't be able to tell you, at least not using mathematical constructs/words. It doesn't help that I can't find any resources like you could for any natural language.

When I asked my teacher she said to practice over and over, but that's all I've been doing these years and it didn't do much to improve my oral presentation. So, I'm asking here in the hope that someone who went through the same struggle or understands the mental process very well and knows what it takes to "fix the computation-presentation bridge", could help me or guide me in the right direction, to overcome this obstacle.

Thank y'all for your time.

Bartenders, and waiters heavily dependent on tips. As non American visiting it is always taxing for me to figure what to tip.

I am more accustomed to price including the waiters salary and rarely only tipping when service is truly exceptional.

This is also the reason I and many others prefer ride shares, price is transparent and upfront, in traditional taxies the negotiations depends on your local knowledge, knowledge of drivers' language etc and your people skills and it takes effort.

You're right - it's just you baiting people into this false dichotomy to make it seem like people are anti-police. I was just calling your bluff. I'll take an angry mob over lack of police accountability, and the police cannot police themselves so the public needs to do it by whatever means necessary even if that harms innocent police officers.

I will always choose the people over the police, even if the people are violent. A public mob is better than a police mob.

Until the police are held accountable to the public, I feel no remorse for anything that happens to them.

> I have a MP4 file and a SRT file with subtitles is there a convenient way to re render the video with subtitles drawn on it so I can use it in places where subtitles are not supported?

You're going to have to reencode it, which is a lossy and CPU-intensive process (unless you manage to get hardware encoding working with your video card, which is possible but very fiddly IME).

> Is it a super cpu intensive process that takes a long time for let's say a typical 2 hour movie?

There are a lot of compute/filesize tradeoffs that you can make. If you don't mind a file that's 2-3x larger than your original then you can do it fairly quickly (say 1/3 of realtime). If you don't mind an effectively uncompressed video (so tens or hundreds of gigabytes) then you can do it as fast as your disks will write. If you want something similar to the original without sacrificing too much quality then it'll probably be slower than realtime.
> Also I wonder if it is possible to put mini pressurized CO2 balls inside the battery enclosure such that if a fire happens they explode and release CO2, putting out the fire?

No, that may momentarily put out the flames but as long as the thermal runaway condition is still present it will reignite. The only way to stop a battery fire, which is actually a metal fire, is to permanently suffocate it - usually by dumping heaps of salt, cement or salt on it which melts and so removes oxygen from the fault area - and then, at least for electric cars, to dump the car in a container full of water and keep it there until dismantling, so that the water acts as a thermal buffer to prevent reignition.
Yeah, it’s hard to predict the outcome/knock-on effects without knowing more specifics so it’s definitely possible I’m wrong about that bit.

I generally think it’s a bad idea though. I’d like to think I could be persuaded otherwise, but the arguments I heard in favor of AB5 or no on 22 didn’t seem that strong.

The sense I got from friends voting no was it was mostly driven by anti-Uber motivated reasoning without much thought about existing incentives and unexpected negative consequences.

The sense I took away from reading about AB5 was that it’s a push to get drivers marked as employees so the teamsters could unionize them and collect fees.

Basically a political battle behind the scenes is the real fight and this other stuff is just confusing the issue.

In that context Yes on 22 seemed like a good option.
IT has gone for the worse and I feel like what SV has turned into is partly to blame.
I don't think the quality of the lecturers matters that much. It's all about the students for me: good students create an environment and expectations that drive the whole thing. An excellent teacher isn't going to drag average students to amazing, but conversely a decidedly average teacher will not make amazing students average.

Also, I am not convinced your average Nobel laureates is a particularly good teacher. If anything, from experience, research focused professors often see teaching as a chore and it has a clear impact on the quality of their teaching. If we're talking about teaching calculus 101, I'd much rather have a no-name professor who is a good pedagogue and loves teaching than a Fields medal winner.
Of course, in reality, the fact you were taught by $famous professor is probably more valuable than what you actually learned in the class.

I'm a software developer and lately I've been thinking that if I would change to work 6 hours a day my productivity would be at least what it is now. It's just hard to make an argument why they should still pay me the same amount when I'm sitting less on my computer and I can't afford a pay cut currently.
$50k in extra debt is a whole lot of money to pay in exchange for the promise of friendship.

But that is about people who don't understand their role as middle management. They should set guidelines and enforce processes so employees that do job think only about working and when they forget about some rules there is management to guide them.

This does not have anything to do with meeting with people f2f, one can use tech tools and maintain policies. Of course having coffee with people all day is easier :)

I won't even bother to read that junk. They clearly don't have the faintest idea what capitalism is but they want to re-engineer societies.

Even in the most extreme cases governments steal and spend 25% of GDP. While it may not seem like a lot (compared to basket cases like France), that is usually more than the entire private sector of a country can afford to invests. And those are best case scenarios. What capitalism???
Uber got kicked out of Israel as well - the taxi driver cartel wouldn't have it.

>But, if A is nonzero, then it must have at least one nonzero eigenvalue, hence one nontrivial eigenvector.

How about this matrix?

[[0, -1],
[[1, 0]]

>However, if v is a right eigenvector with eigenvalue \lambda, then v^T is a left eigenvector with eigenvalue \lambda, as well.

A snippet of code producing a counterexample:

import numpy as np
import scipy.linalg as spla

A = np.random.randn(3, 3)
right_eigenvector = spla.eig(A)[1][:,0]
right_eigenvalue = ((A @ right_eigenvector) / right_eigenvector)[0]

potential_left_eigenvector = right_eigenvector[np.newaxis, :]

# if all components of the following are not the same, then it's not
# a left eigenvector
print((potential_left_eigenvector @ A) / potential_left_eigenvector)
# prints [[-1.1327836 -0.j -0.14850693-0.j -1.84397691+0.j]]
> The financial crisis that brought the world economy to its knees was caused largely by bad statistics. Analysts assumed that the values of mortgages are Gaussian, and that the tails of mortgage values aren’t more correlated than than mortgage values are on average.

Analysts did use models that take into account that the tails are more correlated. Arguably overconfidence on these sophisticated models brought complacency and led to excessive risk taking.

I'm not sure why you're asking or what new features you'd like them to take advantage of, but given PHP's reasonable approach to backwards compatibility, I expect that it won't take too much effort to get Wordpress running on PHP 8, but obviously it's not going to utilize much of the new stuff that way.
Possibly not what the author meant. Support for PHP 8 in WordPress will come soon after PHP 8 is released. But to upgrade WordPress to PHP 8, that is to rewrite its codebase to make use of PHP 8 features, probably will not happen anytime soon. WordPress still has a minimum PHP version requirement of 5.6, so...
So php tries so hard to be Java. Well, just stick with Spring and get the job done professionally. Learning PHP these days is a waste of time.
Main Difference Between Email API and SMTP Relay?
Hi HN,

I'm struggling with pinpointing the main difference between Email API and SMTP Relay.

I've made a brief description of the different protocols for sending and receiving emails; the SMTP Relay uses back and forth communication, while the Email API use direct HTTP calls for sending emails.

The main difference is changing deliverability and sometimes blocking for emails sent with SMTP Relays due to blocked fire-walls, while the Email API is associated with fast delivery and limited blocking since most firewalls allow HTTP connections.

I know there are more differences, but is the description above a correct understanding of the different protocols?

while you are downvoted I think, there's a certain truth to your comment.

Imagine a corporate lab: there's trained researchers, as well as technical/lab staff (preferably with a solid apprenticeship). Now you have a 30 year old technician who worked in the field for >10years and in parallel did some community college BSc, so has at least some calculus, very basic mechanics and whatever domain-specific-science background there is. Both this one and a MIT grad apply for a technical, managerial position managing technical aspects of the lab/department.

I bet, today, the MIT grad is not too far behind, even if he has no idea of the social dynamics with all the people, skills in procuring stuff or even properly doing labwork. Great, not?
Hmm. This stuff is hard to google, but based on https://docs.microsoft.com/en-us/previous-versions/cc194797(... it looks like windows NT was the first version to support UCS-2 (in 1993), so i think utf-8 did exist at that point in time, but its pretty hard to blame microsoft for going with ucs-2 at that point in time.
That's extremely, extremely risky to do if you don't know the cell's composition, especially the liquid electrolyte, and its performance in cold temperatures. Last thing you want to do is manage to get it frozen and physically damage the layers.

I’ve been trying to learn Janet for a couple of days. Janet is a Lisp-like language but in no way a lisp. Janet’s site now delibarely states that Janet is a Lisp-like language not a Lisp.

Janet can be parsed using a PEG parser, so I think that causes it to lose some expressivity of Lisp.

Janet is a cool language though, I like it. I wish there was a decent tutorial instead of just language reference docs. And the Core API documentation is a bit poor in my opinion. I’m trying to submit examples to Core API documentation, I’m hopeful it will get better in time.

Very cool and useful stuff, but aren't CTEs optimization fences in postgres?

If you're dealing with largeish tables and several linked CTEs this might get too slow, and you're still stuck on optimizing your queries manually.

AFAIK subqueries do allow predicate pushdown, etc. Maybe for postgres, composability can be achieved through subqueries.

Nevertheless very cool stuff!
Aren’t there, uhm, lenses that autofocus? I get that are more choices for third party manual focus lenses, and that they’re generally cheaper, but the amount of stuff they’re buying / having to haul around to make this solution work seems to be pretty intense.

I guess this is most interesting for people who already use a gimbal, which is a tool that stabilises your camera for video, because until now you couldn’t use manual focus lenses, or at least not change focus during the shot, because operating the lens manually will interfere with the gimbal’s operation.
