This was super encouraging to read. Thanks for sharing your experiences
> I thought we were against for-profit education?

Jeeze, not everyone on HN has the same viewpoint!

These categories of schools just have different funding mechanisms and thus different incentive structures. Compared to private nonprofits, for-profits can crowdfund creation of the school, but give up some ownership. On the other hand, public nonprofits are controlled by politicians and the general public.

> why did [many people] think that one for-profit is bad, and the other gets a free pass

I suppose for most people it was a value judgement, rather than an ideological one. The same reason why someone might dislike McDonald’s, but still like Veganburg. Bang-per-buck, many Coursera classes are a better value than those at other schools, whether they are for-profit, private nonprofit, or public.

I'm sure this strongly depends on where. I don't really know the state of the world today, but very distinctly remember curves being destroyed in the late 90s early 00s by a flood of professional engineers and medical doctors fleeing former Soviet republics to the US and not having their licenses or even degrees recognized and having to go back to school. There was a time where the quality of students in Los Angeles community colleges was probably higher than an average Ivy League university because of this.
> but where's all the love for analysis & PDEs?

That would be getting too close to stuff that's actually useful.
Nice answer, but it actually supports the point being made here. NLP is an attempt to see how far we can go in processing natural language, without doing this sort of translation, and without structured knowledge bases. As (I'm pretty sure) Wolfram Alpha contains a structured knowledge base and draws on it for this sort of question (though not without help in this case), its abilities are orthogonal to the issues addressed in the article.
Is it possible to use secure boot to boot e.g a Linux environment with something like AppArmor enabled in a way that can’t be disabled without resigning a new bootloader?
My experience, PhD, 10 years postdoc, 10 years in startups (all in UK).

I actually didn't get any hassle as a PhD student, possibly since I was a mature student and wouldn't take any shit, I didn't need to get into any fights but I was willing to and I guess that comes out as confidence.

As a postdoc I experienced several attempts at bullying, all worked out in my favour as I was sensible enough to join the union on my first day at work. I'd say that 90-95% of tenured academics are reasonable and often pleasant people, but high-achievement does also tend to attract a proportion of arseholes, and it's pretty random as to whether you come in to contact with them. How you handle it is up to you of course, I always fight back. The union is your friend.

I find that startups are much more mellow places to work, finding an aggressive and unpleasant manager seems to be really quite exceptional; businesses tend to have "processes" in place in a way that academia just doesn't. An aggressive manager is quickly identified as a bad manager and then an ex-manager, they can't just claim "I'm really clever so suck it up" in the same way as in academe.

I don't regret being a postdoc at all, I met a load of interesting people and worked on a lot of interesting projects. But it's not the whole of the world. I'd recommend exploration of the rest.
I mean, it is a magical field that seems to surround every single observable object (and some otherwise unobservable ones) that propagates at the speed of light. On that scale of weird, magnetism is not particularly special.
Do you have any proof or even hint for your suggestions or is this just a doom 'n gloom mixed with "they are out to get you" paranoid trope of the week?

They also fall for non-deepfaked media as well, and spearphishing, and so on. The greatest threat vector has always been the wetware.

If you're doing trivial things, or things where the data is the content itself, then none of this matters and you would be right. However, if the data is something more "meta" or is tied to the product itself, it becomes a bit trickier. If the app is not just a tool, but the whole workflow of a team or organization revolves around a workflow the app provides, it can be tricky, because the data is not just the content, but the result of the workflow.

Just imagine. You use Duolingo to learn a language and it shuts down. What do you do? What's the export format. Will the new product have the same levels / trees/ etc? Very unlikely. You'll have to start all over again. It's not about the raw data, it's about the data that your work has generated.

If you're doing machine learning, then there's the raw data, but there's also all the other data resulting from your hard work: training jobs, experiment tracking, parameters and artifacts and metrics, models.

The question becomes... First, how important is your product in the user's life? If it's important, they'll rely on it a lot and use it a lot to do things that are important for them, or for their organization.

Then, the service needs to provide export options and send you a shutdown notification. These are not always true but, assuming they are, you'll have to scramble to exfiltrate your data.

Then when you exfiltrate your data, it's an export. You'll have to find another product or service, and then somehow hope you can import that data to the new product, and then set up another workflow.

And here I'm talking about consumer products. For enterprise, there are many parameters including who the vendor is, procurement, team size. Meaning if you are Google/Amazon/Microsoft/etc, then a lot of people will treat you like a utility that will continue to be there, even with the track record of some of these of shutting down products and services (how many products has Google shut down over the years).

Look at this thread[0] I posted about our machine learning platform and the conversation that followed. The person objected that as long as it wasn't open source, they wouldn't use it. But digging a bit deeper, it turns out what they wanted wasn't really open source, but open source was one solution/implementation to their underlying problem. Trust you'll be there or control.

At least, that will be a shared system framebuffer, not applications own memory.
I can only speculate as to why because it's safari which i don't have. If the eval is throwing an exception it's probably something to do with the unicode encoding that packs 2 ASCII chars into each UTF16 surrogate pair - the second one ultilises slightly more of the 20bits available and some UTF16 implementations/interfaces are buggy.

You could replace 'eval' with 'throw' and see if the output looks like sane JS
From my experience, Switzerland is definitely better compared to countries like, let's say, Germany, in almost every area of life - standard of living, salaries, closeness to the nature, taxes, healthcare - you name it.

Average salaries for devs :
- Germany: 50k EUR / year;
- Switzerland: 95k CHF / year.
Of course, it depends on the specific canton/city/town when you want to settle down, but you need to take to account taxes as well. In Germany, they will tax you pretty heavily, around 50%, and Swiss taxation is ~30%, more or less.

Of course those are rough estimations, but you get the point.

In terms of costs of living, it is expensive, especially if you want to live in Zurich, but for a dev earning ~100k it won't be that much of an issue. Of course, you can choose a smaller town and cut down all expenses in half :slight_smile:

Netflix region locks content that they have to license, not their original content. Sometimes content is restricted because of previous exclusive licenses given to traditional channels (e.g. cable).

I imagine that as everything moves to “streaming first”, and old licenses expire, we ‘ll leave región locking behind. Video games are not región locked, even though prices are adjusted for different markets.

Movies and series should move more and more towards a global market. When I was a kid movies took months to arrive to theaters in my country (for various reasons, like reusing celluloid or making better predictions of performance)... now big blockbusters premier simultaneously everywhere because a good portion of marketing is global.
>You either are or not.

This is a lie you tell yourself to be able to continue to look down on people.

In the real world, people are affected by their circumstances, regardless of whether they have the ability to change them.
Thank you for the pointers.
Battery: it doesn't have to be lithium (even thought, currently all planned ones use lithium-ion). Sodium-sulphur would be an option as well.

Biofuels are low energy density: this isn't about aviation or transportation, so that's not a concern at all.

Biofuels don't provide enough power: citation needed (are you moving the goalpost again?) - note that most energy will come from wind and the sun, so there is relatively little need for biofuels.

Burning biofuels releases carbon into the atmosphere that would otherwise be trapped: No, it would be released anyway (well, unless if you burry it really deep).

The problem with nuclear power is cost, due to high risks. And even then, the insurance (which is really expensive for nuclear plants) doesn't cover all the risks. The biggest risk is externalized: if e.g. a power plant in Switzerland would blow up, almost the whole country would be become un-inhabitable. And there is no insurance company paying for that.

You can't make uncle Bob any more media literate than he wants to become. So perhaps your energy might be better focused on being a good resource for helping his daughter/your niece become media literate. And then perhaps that may rub off on him via osmosis.
Among other things: intel has an internal fab that they do not want to let go. This makes them several generations behind on the process. Even copying AMD arch would not help.

What was the motivation for including OO capabilities for a language targeted at embedded systems? The docs seem to make quite a fuss about the fact that it can do OO. As someone who doesn't work professionally in this space I was curious how the domain of embedded stuff is a good fit for thinking in OO?
Yes it possible. The main issue basically as all app basically on one domain localhost so USC can be bad
Correct - the publisher does not have the power to stop used copies of their books being resold, as per first sale doctrine. You can definitely still sell or buy used copies, although one of your most convenient markets (eBay). But that's eBay's decision, they have the right to decide that.
Overloaded Helium tanker?
These articles are terrible.

Quote: "Scuff across a rug, and you charge your body to several thousand volts." Pardon me?

Further down: "Can an object have a certain voltage? No. Why not?" How does that fly with the above statement?

These articles are exactly the confusing non-pedagogical and partially straight out incorrect nonsense that the author criticises in other works.
If by "warp drive" you mean a drive that would be contracting spacetime in front of the ship and expanding it behind, then this ship wouldn't be subject to time dilation.

As it is not the ship that is exceeding the speed of light within a local reference frame (the "warp bubble) but the spacetime.

But the feasibility of such a drive is purely understood at the moment as it seems such a drive would allow for causality violations.
Can you clarify your argument, I don't get where you are going with this? Also once Coursera is on the stock market then you and I can own it and we didn't create the school.
No one said uncle Bob is old. Maybe uncle Bob is your hip cousin who still has no idea how these things work and zero interest to learn it. IMO, the biggest failure of tech discussions is to ignore that technology is there to solve a problem people have. It's not an end, it's a means to an end. People want to know that the video they see which says "filmed in xy" was really filmed in xy and not manipulated afterwards. And saying "yeah, you can just do this yourself, all you have to do is use gpg, make your own signature, distribute it, .." completely misses the point.
I personally absolutely need that piece of information. I have a simple assumption about the material universe. All interactions rely on touch. Atoms or their sub-particles don't magically interact with each other over a distance.

That's why I still don't understand gravitation, at all. I don't care that we can calculate something. That doesn't tell me what is actually happening.
The actions of that cop were horrific and inexcusable. No one deserves to be treated in that manner including Miles Davis's wives and girlfriends whom he publicly bragged about treating in a similar manner when he thought they got out of line.

The UK Open University (distance learning) uses Apostol heavily in its MSc Maths course.

I've put a post about this in their private forum, so you may pick up some interest from there.
Banning anything that's already widespread implies making a part of the population into criminals. With that comes the costs of enforcement and of government's authority (which is finite). Consider too that crypto is, often, a response by many to perceived policy for fiat.
The threat for phishing attacks grows exponentially. When you redirect users to your webpage, they see a padlock in the URL bar, can check the certificates easily, and get a big red warning screen if the URL gets reported. They also have the option to go the page manually, knowing for sure they're in the right place. In their email client they have none of those. As an attacker I could just as well email a form that asks for their old password in the form in order to get a new one.
This is a great suggestion. For any topics like these, starting in very low dimensional space and working through an example is a fantastic way to understand it.

I'd also suggest not only trying to imagine this in your head: implement it in code. That's how I truly learn these types of things.

For extra fun, you can make it into a game. After you've implemented the filter, create a way for a human to input a guess at the filtered output. Score it depending on how close it is. This way you get to practise your intuition for it too.
That sucks, but none of it of sounds abusive.

Depends on how important you are and if you are aware of your own importance.

A lot of important people also lend themselves to bullying either because they are not aware of their importance or because they have some psychological affinity to exploitation.

But it's definitely less in a competitive job market where you leave one company and find another one same week at a different company.

"Just make it one click to store it in a wide selection of remote storage options" is easier said than done. From the standard user's point of view, they don't need to be reguarly exporting, they can just use that option if they want to change apps or if the app itself is at end of life.
Yeah, it isn't something that is feasible if you can't tailor the infrastructure to the underlying data. An SQL backend is about as generic as it gets, hence the poor results. Enterprise DB deployments get away with it because they can justify throwing a lot more hardware behind a centralized generic data store.

Give that second link a closer look if you change your mind. It demonstrates a way of indexing 1.6 billion 80B strings in 24GB, and then returning the result of a fixed string search in 100ms. That is the reward you get when you venturing outside of the LAMP stack: less resource consumption, greater performance, increased utility.
It is huge.

In some languages voltage is called "pressure". I think this is also a good analogy because just like how you get energy from a pneumatic system by exploiting a pressure difference, you get energy from an electrical system by exploiting a potential difference

To any authors reading this:

It would be cool if you would set up abilities to "donate" or direct pay you. I love getting ebooks but often its really difficult to find a drm-free version (sometimes I can get one on the publishers website).

Because there's so much friction around it I get virtually all my books from pirated sources. For books that I really enjoy I'll then go pick up the book at my local bookstore, but I'd love to have an easy, digital way to pay you.

Would be even cooler if you had a cryptocurrency address (ideally monero or maybe bitcoin) I could pay.
The traditional way of solving this problem is to assume stronger social obligations -- to a spouse, and to family, and sometimes community.

I realize some people won't do that. But we're talking about tech CEOs, so these are people who have some control over their lives. If we re-normalized those social obligations, I think it would be better than transactionalizing it.

And it's not all-or-nothing. I've tried to arrange my life so that I can make enough money, but also spend a lot more of my time doing the things I value more than money.
Files are an implementation of "your stuff", using standards based storage to simplify managing "your stuff" should be the goal.

Show HN: I have curated a list of 127 remote companies
When we are looking for remote jobs we generally browse job postings in remote job boards.

In doing so we miss some opportunities which are not posted in those job boards.

So if you are actively looking for a remote job you should also checkout career pages of companies which recruit remote talent.

I have compiled a list of such companies and tagged each company with remote locations they are hiring for.

Those who are looking for remote job do checkout this page.

They're both valid definitions. My more earnest point is the trend of being less involved in more communities. And the corresponding shift in intensity from "all of your lives depend on each other and almost no one else" to "you all make money the same way".

And that shift is accelerating. Agriculture caused a big jump. The industrial revolution caused a big jump. The internet caused a big jump.

I don't think it's all bad. It's just different. My idea for the healthiest setup (covid aside) for modern work is remote in a friendly, local coworking space. That way if you change jobs, you only change half the people that you spent 9-5 with, not all of them. There's a resiliency from diversification.
I’ve experienced no abuse as a PhD student. However things have happened around me that could be interpreted as abuse. For example our group leader used to love confronting people who didn’t understand certain concepts. I don’t think that’s abuse but some might
It’s not as common but the incentive structures in academia are uniquely enabling to abusers. In industry it’s much easier to leave tyrant bosses. I agree with your points.

Many of the positive incentives don’t exist in industry though, an “up and out” culture is rarer in industry. When it works in academia your supervisor is positively invested in your growth, in general in industry your supervisor doesn’t care about your growth. If they need someone with new skills and you learn them fine but they can also fire you and hire someone with those skills (even though this is probably a net negative for them due to retraining on job specific stuff, it’s still seen as a net positive by management)

There is less abuse though. Full stop. Sorry you’re in this situation.

Thank you for the feedback. I realize it is important to introduce myself when sending out an invitation to join a book club like this, so I have added an FAQ section at https://spxy.github.io/bc/#faq where I introduce myself. I took the liberty to be elaborate there because I am not well known outside of a few very small communities.

By the way, I briefly talked about this yesterday at https://news.ycombinator.com/item?id=26355752 where I mentioned how a small tech support channel evolved into a computer science and mathematics literature club. The parent story of that thread inspired me to make this post today.

To all supporters on HN, thank you for the bringing this post to the front page. I honestly did not expect this to come to the front page. At most, I expected a few people to notice it at /newest and join the book club. However, since I created this post, about 25 new members have joined which is great!
Why is it downvoted? Because it’s implying that selling your information to advertising companies is a good thing, because it increases competition, and regulations making that harder are bad

The problem is that you could frame almost anything like that

Take an extreme example:
Let’s imagine gold traders were allowed to go around taking people’s jewellery at gunpoint. Gold would be cheaper to buy. Traders make more profit. More jobs! Surely this is a win all round?
Of course not, for obvious reasons.

This isn’t true of the vast majority of files.

People could do a lot with their photos, videos, music and movie files that were stored in standardized formats on their hard disks.

Witness the plethora of music and movie players, the tools formed around images and video browsing and manipulation, etc.

Even non standardized stuff like word and excel documents could be shared, backed up, organized using these files.
