> However, I've always failed to see the practical interest of categories. It's nice to see how various things can be described or defined in a categorical framework. It may shade new light on some concepts, but I didn't see any useful theorems you could apply (like in vector spaces for instance). Probably I didn't go deep enough.

Almost by definition, you can't see the point of category theory until you go deep enough. Because statements in category theory are, in a very profound sense, statements about everything, they must logically be less substantial (or at least no more substantial) than statements about any particular thing.

If that is so, then why bother making these less substantial statements? The point is precisely that they do apply to everything, so that your knowledge about categorical statements pertaining to vector spaces instantly translates to knowledge of exactly the same statements about groups, or modules, or … whatever (as long as the relevant categories satisfy the same hypotheses).

That is, from my point of view at least, the utility of category theory is almost never in what it has to say about any one discipline, but rather the connections it makes, or at least the 'automated transfer of knowledge' that it allows.

EDIT: Also, I think that, much like the monad tutorial profusion, the large number of resources for learning category theory makes people think that they are obligated to go out and find a use for it. I think one is much less likely to be successful with the mindset "where can I use category theory?", and much more likely to be successful with the mindset "I have this language in my lexicon, and so will recognise the opportunity to speak it when it arises."
Google has ~24 billion in revenue. Twitter is harder to pinpoint but from the sources I've seen it's far less than 50 million. Facebook is somewhere around 400-550 million.

I guess my point is that they aren't even in the same stratosphere. Twitter and Facebook may be international recognized (and clearly I should have differentiated here), but they aren't in any way equivalent to a behemoth like Google.
When you're in a good class with other smart people, you get to see their brains in action. You end up talking about interesting things with the classmates you like, and who like you. This is the foundation of a genuine intellectual network. It is difficult to obtain this seed network in any other way, except perhaps by email in a hopping open source project, or by getting into an interesting clique like Y Combinator.
It may not be just the lectures that matter, but I definitely learned a lot and developed technical maturity as a result of my courses. Could I have learned them on my own if I had known exactly what to study? Maybe. Were there bad courses along with good ones? Yes. Are there bad students that still get degrees? Yep. Was it worthless? Absolutely not.

Example experience that could not have been had outside college, by definition: after taking the introductory computer science with perhaps more enthusiasm than was wise in my first semester, I TAed the course for my remaining 5 semesters. Obviously, my experience was not typical. On the other hand, if your experience is typical, then you certainly need to learn from courses rather than trying to do it all through self-study.
How much of this list is currently present in the nightly build of Webkit?
It is for East Asian language support, though, which may have an indirect connection to Ruby, the language, since it's from Japan.
The rest of the word might hesitate to consider the person "not dead" when their body, their instantly recognizable human feature, has been taken away from them.
Yeah, blocking works well. I removed 90 out of 95 RSS feeds I followed and I don't miss them.
awesome!
facebook style tagging on twitter.
thanks. not exactly positive :(
Also as a front end developer (who does UX / design), I think I can get about 80% in most situations, but the additional 20% is what makes sites like airbnb stand out so much.

In those cases, I'm happy to hire someone and code it myself, after all, I'd much rather they be knock-your-socks-off-good at web design than someone who is only decent at design, and okay at integrating.
Your bug is my feature.
I could easily see playing an instrument turning not-fun if you do it as a full-time job, especially if you're doing it as an employee with minimal creative control, in a fairly big organization, which is the place a lot of programmers find themselves.

The musician version might be: playing guitar in a Las Vegas casino's house band. Pays the bills, but it's not many musicians' dream, and it surely gets un-fun after a few weeks, let alone years.
> it is super obvious you are not comfortable with this guy and don't trust him

If you don't trust someone, then regardless of how the numbers add up, it's almost certainly a bad idea to have him as a business partner.
jQuery requirement doesn't suit me because I am currently using YUI. Are you planning on making YUI version available? If not it would be nice to have a version with no framework dependencies.
It's not unreasonable to extrapolate from "got it from a friend-of-a-friend" to "quite a lot of people will have this".

Yes, one should notify the professor; but I think it's acceptable to do this a little less publicly (e.g. by writing it on the test or sending an e-mail), if one so desires.
This is very much a real world problem. It seems that the author of this post has written it out of frustration, hence the title.
But in the end, I couldn't agree more. If you are a visual designer and you solely design websites and you can't do HTML/CSS, you have no business being in that role. Period.

I don't think any browser shares all the peculiarities of any other browser. That's hardly an argument against there being a W3C spec for HTML, CSS, the DOM, or JavaScript. Why pick on SQL?
Oumuamua seemed to accelerate as it moved away from the sun. A space rock moving only due to gravity shouldn't do this, though a comet might.

Gravity slingshot. Humans have used that effect themselves. There's nothing mysterious about it.

My mother read a book to me called "The Emperor Has No Cloths" when I was very young. The book is silly, but it stays with me to this day. Every time I hear my president repeat absurd, dangerous and divisive conspiracy theories, this book always comes to mind. Same goes for the supporters that defend him.

Public debate is fine, but we are watching a huge population of people absurdly follow this man in his birthday suit. People so easily "persuaded" deserve the (non violent) pushback they get.

"The study, published on 17 November by researchers from New York University, Abu Dhabi, combed through more than 200 million scientific papers to identify several million mentor-mentee pairs, then tracked their co-authorships and citation records to evaluate the impact of mentorship. Their conclusions, including a finding that “current diversity policies promoting female-female mentorships, as well-intended as they may be, could hinder the careers of women,” angered many researchers. Critics attacked both the study’s conclusions and the methods used to reach them.

In a retraction notice published today, the authors wrote that they recognized the validity of some of the complaints, including concerns about “the use of co-authorship as a measure of mentorship.” "

Wow, they used co-authorship == mentorship and from that assumption concluded that women-women mentor-mentee relationships result in worse outcomes? That's one hell of a reach. How did this make it past peer review?
The 3rd most popular journalist in the world is a random dude? Do you even believe yourself?
The trespassing and sacking of the capitol is precisely a sign of backsliding on traditionally liberal ideas from the enlightenment, much more so than Twitter banning the number one inciter of the aforementioned insurrection.
Not exactly.

A newly typeset and printed copy of Alice in Wonderland does have copyright protection. The presentation has transformed the (public domain) text enough to qualify for protection. Someone chose fonts, letter sizes, line lengths, book size... You can't go making photocopies of that particular work and sell them without infringing.

You can, however, take the original text, which is now in the public domain, and typeset and print your very own Alice in Wonderland book. And now you hold a copyright on a presentation of Alice in Wonderland.
That part shocked me the most. History is one of the most eye-opening subjects you can possibly learn, and requires significant critical thinking skills to be able to really understand things. Think a big codebase is complex? Try understanding the motivations behind ancient law systems, and how they affected their peoples over the centuries.

Not to mention the perspective it can offer people. There are so many things repeated throughout history which could have been avoided had people focused more on an objective understanding of the past.
As a counterpoint, I started programming when I was 5, and have known what I wanted to do since I was 7 (shortly after writing my first program that someone else used). I did my first commercial software project when I was 16, and got stuck in 'trying new things' for several years because people (for example, parents, family, teachers) around me told me that I didn't really know what I want.

Doing that set back my career by several years over where I could have been.

If this was happening at an earlier age, it would be more questionable, but for the vast majority of human history people already knew what they would be doing for their lives and had training and experience by the time they were 16. She is young enough to change her mind, and will still finish high school. As for the social aspect, did you miss the part where she will attend a different education program?
I have made several Broadcom-equipped laptops more Linux friendly by installing an Intel wifi card. They go for about 20 or 30 bucks on eBay. I don't know if the MBA has replaceable components like that though.
I think one drink per 2 hours is pretty reasonable. Maybe it should be one every 1 hour, or maybe one every 4 hours is reasonable. At the end of the day, it's convenient and helps make the coffee shop owners money, but it's not a coworking space, and I'm a fan of "fair share".
There is almost no regulation (insider trading is fine for example). Leverage is huge so it draws in the get rich quick people. FX has dealers instead of brokers, and I'm told from friends who have dabbled in FX trading, feels like a conflict of interest.

My method: Keep going right until it says you are wrong more than once. In that scenario, go left. Now go right again, and continue. If it catches on, change it up a little: Continuously switch to the other side when it starts catching on.

I can beat it about 80% of the time with this simple method. You just need to think: What wouldn't a human do when trying to be "random"?
Forgot to mention: algodeal.com

Never tried it myself and can't vouch for them, but it seems to be an interesting concept and might let a lot of hackers get their feet wet without any monetary investment.
Thanks. The pages were displaying correctly on my machine. However I think Super Cache compression was partially to blame.
A big variance is going to occur in any direct elimination competition (which the world cup is after the group stage).

(This has always bugged me regarding the baseball playoff system. It is a big boost for teams economically but for purity I would prefer to see just a NL and an AL league table).
Excellent point. IME, billing upon shipment is the standard.

The only time I've been billed so far in advance of shipping was with Alienware in 2000. They were still a small company, so they actually called us on the phone to ask if they could bill now and ship in 6 weeks when the machine was ready. It was an unorthodox request, but we agreed. However, if they had billed us 6 weeks before shipping without asking we would have raised Cain.

That said, it is abundantly clear on your page that the item will not ship for 4-6 weeks.
Not surprising. I guess it happens everywhere.
Out here, you visit some obscure town, and as you get off the train, you realize everyone is speaking Korean or Mandarin.
I guess it's a combination of family moving near family, and friends moving near friends (sometimes coupled with political ties -- e.g. the Hmong population in Minnesota).

hotornot solved the problem by moderating all photos before they were pushed to the general public. this approach obviously wouldn't work for CR.

your suggestions are pretty good- i'd be somewhat surprised if these sorts of things weren't in place already.
The point of hashing passwords is that the true password is not revealable.

The point of salting password hashes is to prevent identical cleartext passwords from being stored as identical hashes in the database. Salts are often stored in the database, as well.

The point of peppering keeps a database dump from being at all useful for recovering passwords. It make sure that a component of the process of cleartext -> DB entry is not even in the database, requiring something from the app as well.

Why does encryption work here? Because you've already done a one way function on the cleartext -> salted hash. At that point, there is still no way to reverse the process all the way to get the cleartext. By using a two-way encryption function for the pepper portion, you keep the ability to rotate 'peppers' periodically, in case it is leaked, for example.
Why the fuck am I reading this on hacker news and not from a notification in slack?
That was actually a lot more fun than expected, thanks for sharing!
"In practice, I rarely reply to emails or GitHub issues, even if the sender sounds sincere. I've found that once you start being nice, some people will keep asking for more and then get angry when you don't keep volunteering your time.

Silence is the only scalable solution. I know that not making myself available feels unwelcoming and not inclusive; but I'm paid in my day job to serve students at my own university, not strangers on the internet who are using free software that I maintain in my spare time."

An interesting comment given past discussions on Hacker News about how demanding some users are about open source software (these users often tend to be other developers too).
Devils advocate would be to engage with the core of an argument, rather than nitpicking my characterizations. The larger point there is that both of those actions don't themselves have any effect outside of some isolated context. This necessitates using invasive methods to police them and also uneven enforcement ultimately based on other circumstances. Each of these aspects causes terrible results that undermine the rule of law itself.
All spending bills originate in the House of Representatives.
The backpack that came with my ThinkPad.

Wide comfortable straps, padded back, sufficient pockets, enough room for light business or personal travel (change of basic clothes, etc), pretty robust.

Given the volume of them I see in airports, I'm surprised I'm the only one mentioning these.
How about having a card 'linked'?

As far as I know, PayPal have no history of stealing money from linked cards.
This "yOu cAn't mAkE nUmBeRS iLlEgAl" thing is one of the most annoying memes I've ever encountered.

It's literally self defeating - you could just as easily say that he has no right to privacy for the contents of the harddrive because the contents of his harddrive is "jUsT aN iNtEgEr" and no integers are secret.

Some patterns of bits are clearly and rightfully illegal.
Thanks - really interesting.

Take this one, for example:

nvidia Drops Support for CUDA on macOS

--> CUDA 10.2 is the last release to support macOS

--> CUDA Toolkit Release Notes

The first two titles are quite interesting to me, as a macOS user and a general follower of the tech space (and I'd note neither are sensationalised, or click-bait, from what I can see). The last...? I'm not going to click on that in a million years, as I don't work with CUDA.

I'm not totally clear what the moderators' motivations always are, but might it be true that in some cases, maybe they're prioritising strict accuracy over interest, or discoverability? And as a result, their actions are actually diminishing the value of HN as a discussion forum?
You can’t make up in volume what you’re losing in margins.
i’m strongly convinced, but would genuinely love a strong counterargument, that the single clearest US foreign policy priority since WW2 has been the establishment of free markets. My perception is that we are supremely confident that we can outcompete anyone, anywhere. We just want a market where we’re free to go head-to-head
Established US defense/space industry does not want to make it easy for SpaceX to enter the market. Simple as that.

Since many generals leaving AirForce join the major firms as basically lobbyists, you can see where that's headed.

It's not REALLY the AirForce that's making it hard. It's the established space launch firms, using their newly hired lobbyists.
S3 could do the exact same thing tumblr just did (though for different reasons, granted). This is the risk of the cloud in general (or really of outsourcing ANY labor in general) and is not isolated to tumblr etc. More a question of where you draw the line in terms of price/risk.
For what it's worth, I hadn't heard the name until thirty seconds ago.
byzanz-record with some manual cleanup in GIMP.
That sounds right to me. Only a few commands would need this facility. But when you need it, you need it. A long-running script should NOT lock up Redis indefinitely.
Yes, but who watches the watchmen?
This is great. I hope this kind of screening tech, like this, becomes commonplace and highly available. Early detection could save many lives and greatly reduce later stage treatment costs.
> The framers of the Constitution and the Bill of Rights intended that the total population of Congressional districts never exceed 50 to 60 thousand. Currently, the average population size of the districts is nearly 700,000 and, consequently, the principle of proportionally equitable representation has been abandoned.

Non sequitur, and in the first paragraph. I mean, yes, if we had more districts, you could get closer to exactly equal population per representative, but a difference of a factor of two in a few districts is not an "abandonment" of the principle. It's the principle not working perfectly, which is perhaps not ideal, but is far less end-of-our-democracy than this tries to make it sound.

And if we did expand the House to 6,000 members, what would we get? We'd get 1000 self-important committees, or we'd get more members per committee, or both. Can you imagine the impeachment hearings if the committee had 500 members, each demanding their 5 minutes to grandstand with each witness?
VeriSign wants price caps removed like .ORG managed. They are salivating. Their fingerprints were all over removing price caps for .ORG. Those same lobbyists are still involved now at ICANN in the groups, subverting the public interest.

Ha. 3x the local 1br apartment rent would put minimum wage higher than my current salary as a software engineer in the bay area (granted, I'm a government software engineer, not a FAANG software engineer). I don't know how many localities this would work for, but given the comically high wage (~$55/hr) you would get in many bay area cities, I'm guessing it's not many.
1) What makes you think your mother would be "competing" against people receiving UBI? Economy is not a single sum game, and there are several studies suggesting that the boost it would give the economy would actually free up more money for social services.

2) I am not a Yang expert, and agree with you on the dangers of an information autocracy, but from what I understand he is not against breaking up big-tech, he just doesn't believe it will by itself solve the fundamental problems society currently faces with respect to tech and believes other solutions are necessary.
Capsules papers don’t strike me as particularly groundbreaking. Still convolving over every single location in the input image, still using backrop. Vectors instead of scalars for activations and a novel way to pass signals between layers? Sure, why not. But if it wasn’t from Hinton no one would’ve noticed. The initial results were underwhelming, and there has been zero progress even 2 years later.
I had a pair of Allbirds and they were super comfy and breathable but the soles were dangerously bad. Walking around in slushy weather they were like ice skates causing me to slip and fall more than once. I know they're not winter boots but even a pair of regular sneakers were 100x better.
Where is the photo of the founder wearing a black turtleneck? I won't believe the results until I see that.

Yeah they aren't facebrick employees - according to facebrick. To really screw people working for you hire a contracting service to be the pointy end and do the thrusting for you. Every single thing about facebrick is absolutely vile. Nobody has yet considered all the dimensions in which they are repugnant. The more you find out the more sick you feel.
"I think that the average age of a Perl developer is about 35 years (I have no official data for this, my hunch is based on the people I saw at numerous YAPCs I had the opportunity to be present at).

Assuming this is true and assuming a dev enters into production at 23 years old, it results that the average Perl developer has 12 years of software development experience.
What kind of code would you prefer in your business critical, money making software products? one written by people with an average of 12 years experience in the language of choice"

Whoah, hang on there. Even if they did have an average of 12 years of experience, it hardly means that it's been Perl all this time.

Obviously the reasoning that led to this bit isn't rock solid, either ;)

"[...] or one written in a language that appeared on the radar in the last decade:
Ruby on Rails, the framework that made Ruby popular was launched in late 2005"

2005, that's 9 years of experience at best. How lame in compare to 12 :)

Micronutrients, even in hair. Trace metals, especially after chelation therapy, when the results are definitely misleading. Labs that associate Candida with everything. "Stealth" virus testing.

Outrageously large (>50-100 component) IgE allergy tests.

I didn't strike out on my own to write in a language that doesn't make me happy, with thousands of over-engineered libraries that don't do anything I want to do, that's owned by a company that's running around suing people.

After a certain point, there's a base of libraries that is Large Enough. I've never really been wanting with Ruby, at least not in the 'oh, but there's this Java library that does exactly what I want' sense.

Even then, JRuby would make it Just Happen, or maybe even SOA.
