I did some benchmarking for a dictionary app a while back, and the fastest I could get was strstr(), if I recall correctly. It substantially beat std::string::find(). Using a loop is bound to give terrible performance; for large data you

I'd say SF is more mid-California, compared to what's north of Sacramento. North of Sacramento is pretty rural, full of people wanting to implement the State of Jefferson. But you're right, there isn't much in the way

But you also have to calculate the opportunity cost of having a bunch of money sunk in an asset that (apparently) didn't perform spectacularly. By renting he could have invested that $200k in an S&P 500 index fund. Assuming he bo

Why shouldn't they be similar? Seems reasonable that a "legal person" should be subject to similar taxes as a real person. And from a fairness standpoint, it doesn't seem fair that Google is taxed 11% on $billions of i

Your assumptions are wrong, or you have confusion based on wording. By definition, net profit is after taxes and expenses. By definition, one always keeps 100% of net profits. If by "profit" you meant "gross profit" (

The most interesting point of the article to me is that fact that taxes above $100k were 70% - 90% until 1970. That seems like it nicely explains why income inequality and CEO salaries have increase since 1970. With a tax rate like that,

Personally, I think ethics mostly boils down to "I treat others like I want them to treat me." If you would not be okay with your washing machine repairman selling out you and your dissenting friends to the government, then you s

A real doomsday prepper would have bought some land in the middle of nowhere (so hordes don't want/think to come there) and learned how to farm it. Storing six months of food or whatever is preparatory-theater and doesn't

If I recall correctly, Win32 let you stuff a 32-bit value into a window. If you wanted to write an object-oriented application, you'd stuff your this-pointer in that 32-bit value. Since every little thing (button, label, checkbox) is

Maybe the solution is to have a video game movie that highlights the choices taken by the character. Make the decision points important to the movie, rather than remaking the overall storyline.

Ford was never considered a monopoly. GM and Chrysler have been around since the early days. And even in the Model T days there were plenty of other cars. Also, Ford never went bankrupt, you might be thinking of Chrysler or GM, both of w

After working in large codebases I discovered that there are all sorts of assumptions in the code, and that a small change in one function can break an assumption used a long ways elsewhere. I came to the conclusion that any change basic

Tesla says that the driver needs to be constantly watching the road in autopilot mode. But what kind of autopilot is that? If I have to constantly pay attention, I might as well just drive. I think it's safer, too, since I am bad at

I don't know anything about Solaris Zones, but I'm guessing that the FreeBSD jails wouldn't help with the problem in the article. It's still the same kernel running in the jail, so the fadvise calls are going to bottlen

I can't seem to find any easily accessible documentation on this, but it sounds like a container is basically an chroot jail: you copy over all the libraries and files into a subdirectory, chroot into it, and run. Am I right? And if

What were you studying? How do you know that your professors were wrong (that what they taught should be unlearned)?

Study Physics. I'd take the math prerequisites and not understand what this is useful for, and then the first week of physics class we'd review the math and suddenly it would become quite practical.

I think the market for liquid-cooled desktops is pretty niche itself. It just happens to be a niche that Apple is not interested in. Whereas for the majority of people, a regular iMac is just fine.

Depends on what is going on around you when it happens, how long it takes you to realize that something is wrong, and what to do about it. It wouldn't surprise me if many people would not even realize that they have power assist in the

If you learned Ada, Modula-2, Pascal, or BASIC, though, it might not be so relevant. COBOL, FORTRAN, Smalltalk, and Perl 5 are somewhat useful, akin to, maybe, jQuery in the web world.

It seems like free trade is beneficial when you're at the top or among relative equals. The educated people you are talking about are presumably American and/or European, so they benefit from free trade. However, countries that

Probably a bug in using that function, though: 1 billion years is the rotation period, not the rotation speed. The rotation speed is 2 * pi * r / (1e9 * 365.25 * 86400), where r is the distance from the center of rotation (in meters)
