Does anyone know the origin of "usesomesillystri" as a salt? Googling that string found more results than I expected, but most of them are from password files with no explanation. I found some PHP example code that tries to use &q

It's just not worth tickling the dragon's tail. What would be the motivation for anyone to even try (except for maybe government-sponsored hackers in China who are probably safe from extradition and personal blame)? Even if you bo

The lenses project the image plane such that your eyes focus as if they were looking at an object about a meter away. It doesn't cause the kind of eye strain you would get from trying to focus on something an inch in front of your face

The article doesn't go into much detail, but it may be safe for scale reasons, like the oligodynamic effect where metals like silver kill bacteria but can be safely worn on the skin. The research paper [0] indicates that they coated co

You're reading the sentence correctly, but I think it was a typo and was probably intended to say: "We need to improve C++ to sustain the momentum and to better serve the C++ programmers, not out of fear of competition." The

Muons also carry a negative charge, although they're unstable. (and of course there are antiprotons, if you count those)

When you say that boiling results in acidic water, are you referring to the fact that pH-neutral water would be slightly more acidic than your (slightly basic) blood, or is this about dissolved CO2 or something else entirely?

Distillation would essentially be doing the reverse, "boiling the water out of the lead", and that would work. But no amount of boiling in a open pot is going to remove lead from your water. It's hard to tell from the article

While the article admits that this isn't very secure, I think giving any visitor a one in three chance to "authenticate" with any given mobile number is well beyond "not very secure" and into "false sense of se

One issue with this is that the text of the C standard isn't actually enough to unambiguously determine what the committee (and compiler vendors) intend for the language to mean in practice. The official standards mailing lists for C a

Aside from the fact that they carried that style of naming over from Objective-C, the one benefit I see is that it makes it obvious that it returns the result in a new string rather than modifying the object itself. In C++ you would need to

This makes me wonder if there is a simple procedure for doing a pseudo-double-blind study on oneself (without a third party). That is, trying something that can be prepared in pill form in such a way that you don't know during any give

I think you misunderstand how "rootless" works. Nothing is stopping you from using "sudo su" if you want to be root for some reason. The new security features prevent certain system files from being modified even if you

Intentionally disabling security settings for your entire application just to allow advertising from companies who haven't upgraded their infrastructure seems quite user-hostile. Google is a big supporter for HTTPS, strong certificates

I'm guessing the idea here is that the IRS is changing how they interpret their own internal policy for how they will use the powers given to them by an existing law, rather than outright passing a new law with retroactive effects. ...

Cat's whisker diodes and the initial discovery of the LED are other good examples of this. Connect a small wire to the right kind of rock (or rusty old razor blade) just right and you get a diode. If you get it just perfect (and use th
