They're generating the certificate, not the keys. Those are different things. You can probably think of the certificate as the computer equivalent of photo ID for the server. They both show who you are (Driver's License: your na

How is python substantially different from javascript in this case? Google has a crazy fast javascript JIT compiler, even though javascript has something equivalent to python's setattr().

It sounds like maybe you are most familiar with GUIs or the web. Curl is a UNIX tool and doesn't work like those things. If it's the only unix tool you use, that might seem jarring. Of course it would be a smoother experience f

"Simulation" in this case is just numeric integration the hard way, even though there's a closed form solution. This is a calculus problem, not a programming problem. After you solve the real problem, the programming is triv

But, I don't want to do TLS. I'm not in the encryption business. Instead, I just want to send data across the network. The OS used to do the networking for me. It exposes the BSD sockets API, which is pretty simple and nice but

I'm not sure there's only one line to be drawn. There is absolutely a place for an API like this -- but that place is not as a replacement for OpenSSL. The world has changed. We must now consider send(2) and recv(2) to be toxic.

Yes, credit card numbers are used as passwords and need to be secret, but that doesn't change the fact that they are also used as names and need to be public. This is the fundamental problem. We're using a single thing both as a

Wow, that's almost as bad as sites that ask for my credit card number. Of course, my CC number is like my name: public information. Unfortunately, the companies behind the card seem to think it's more like a password. While the

I love when that happens! That's because I hate being wrong. I really really really hate it. I hate being wrong so much that I'm extremely grateful when people point out my mistakes. Then I get to stop being wrong and start be

That doesn't make any sense. What happens when you need to change the SQL? To an application developer, this looks like nothing more than a code generator. Generated code is not source code and it should not be edited directly. Rath

This seems wrong. The boat never moves when Sail Angle is 0. Boat Angles of 40 and 90 should cause motion with a Sail Angle of 0, but they don't.

I'm not sure that I understand the big picture here. Is my summary correct? This optimization does not apply to Postgres in general, but only to citrus_fdw and other column-store foreign data wrappers. The Postgres execution engine wa

When you're in 2nd or 3rd grade, it's more important to learn the mechanics of subtraction than to understand why it works. Kids at that age need to fill their brains with facts so that they have the raw materials for developing

No, it's not printed in your trivial example, but if you replace the simple "echo" command with any bash script, or any executable that calls a bash script, or any executable that invokes another program that calls a bash scr

For jquery, the page is often on your server and the script is on a CDN. The worry is that if an attacker compromises the jquery source on the CDN, they can exploit thousands or millions of sites on as many different servers. If each of t

Of course, but the point of the article is that blanks for high security locks used to be much harder to come by. Now, software and 3-D printers make it easier to defeat the feature that makes them "high security". The implicati

This article was only mildly interesting to me. I think there is a better story tangential to it. The article is only mildly interesting because it gets at the truth behind the idea that Eskimos have 40 different words for snow. If I didn

Ah, thank you. That's what I assumed the policy was, but I wasn't sure if it was implicit or explicit. Now I know. I guess the point I'm attempting to argue is that this particular policy is suboptimal and should be changed

But, HN titles are content. They are part of the conversation about the article. I agree that authors should be able to title and summarize their own work, but only in that work. They shouldn't be given any special control of th

I would assume such changes come from a desire to be accurate. But accurate how? In what way? That depends on the purpose of the title. As I see it, our differences of opinion on this topic stem largely from misunderstanding it. I think

Fahrenheit is pretty easy. The key temps are 30, 60, 90: -30 is dangerous, hibernate. 0 is frigid, wear a thick coat and warm pants. 30 is cold, wear a coat. (freezing point of water) 60 is cool, wear clothes. 90 is hot,

I think the core of the argument is that most software problems are becoming easier, which means the talents of the very best just aren't applicable or especially useful. If something is easy enough, anybody can do it, and do it nearly

Perhaps this is one of those white lies we tell to justify doing the right thing. A dishonest means to an honest end. Is this maybe how researchers publish negative results without having to admit failure? We often complain about the dear

Genius? A weak man can lift a small rock. A strong man can lift a large rock. But to lift a ten ton boulder, you need a crane. Even a weak man can operate a crane, if he knows how. Your genius is like a strong but stupid man. Maybe he o

That's a lot of digits. It would be interesting to interlace the latitude and longitude bits in such a way that any prefix is a valid code of reduced resolution, and you can add arbitrarily many digits for increased precision. I think

Speed limits only apply on public roads. They are a condition of using the road, not a condition imposed on your vehicle. You could build a private race track and drive as fast as you want.

I'm a realist, so I understand and accept that the Pentagon's main goal is keep its budget healthy. What I don't understand is why can't we do that in a way that gets us good airplanes? I'm a wary optimist. Trust,

That argument works even better for cars. Cars are much heavier. It's far more effort to stop a car and get it going again than for a bicycle. It would dramatically improve gas mileage if cars could ignore stop signs.
