It's very common for daemons/servers to chdir("/") at the top of main. Relative paths sent by clients getting broken is a feature, not a bug. (In fact I just fixed a bug related to this an hour ago because a relativ

If it's a relative path, then changing the working directory will break (chdir("/") is a very common tactic at the top of main()). It's possible/desirable for the parent to change the PATH of a child process, p

Well that's true, but also something that can't be addressed within a currently running process afaik.

Those are all cases where you're using argv[0] as an argument to the program where it's appropriate. Using it as the path to spawn a child process is incorrect . You're free to re-use it as an argument. I have fixed enough s

clang does this too.

Don't do this - if you (reliably) want the path to the current executable there is no portable way to do it, but on Linux you need to readlink /proc/self/exe and on MacOS you call _NSGetExecutablePath. I forget the API

It seems like the test is starts with a clear green or clear blue and then devolves into cyan and asks if you think it's blue or green. I think it's blue or green hinted cyan.

This is an accuracy vs precision question - an iPad is not an appropriate tool for the job even if there are hacks to get around its limitations. You should consider buying a different device for this purpose. You can learn C on a Raspberry

Sure, when the cameras start turning into a source of revenue then the city has an incentive to adjust the timing of the lights to maximize revenue and not minimize harm. This has happened (notably, the city of Chicago reduced the time of y

Red light cameras have perverse incentives that have led to municipal corruption and made intersections more dangerous.

One reason calculus is a good prerequisite for CS is that it's typically where you introduced to the concepts of limits and are taught how to look at a formula and see how it behaves at extrema and critical points, if you're good

I think you're making broad statements about macroeconomics without thinking too hard about it. If you're spending $X in rent and have $Y in cash, whether or not it's better for you personally to put that money into equities,

The actual number of residential properties owned by hedge funds is a pittance compared to the number owned by individuals and small time land lords. So I have a hard time seeing how they're pushing smaller competitors out of the busin

To be fair, the income isn't "free" and the margins are basically zero for small-time property owners on the rent itself. The bulk of the income comes from appreciation in value of the real estate, and when you sell you owe c

That's a very different situation than the one you initially replied to. It's also not something everyone can do.

The problem is they can't give the owner an adequate price when they're paying for the owner to grow more equity in the property while also needing to save at a faster rate to afford a downpayment on a mortgage.

Housing prices are publicly available information, rents should be too.

I think you're missing that in order for your employee to do that work they would have to access public information, which is also available to renters. If on the other hand, you got an employee to call up landlords and get the rental

That is not true for pipes.
982.
by duped 2y ago
It doesn't that's why no one does it. But for pipes what it means is that if whoever is reading or writing the pipe expects non blocking semantics, the other end needs to agree. And if they don't you'll eventually get an

To be a sociopath for a second: Up-front pricing is only good for the buyer and never good for the seller. And while being an advocate for the user is a good thing in general, it's not a good thing if the result is less revenue. And if

Because there's two decades of revenue between that happening and today. It's far more likely that Uber buys Waymo than Waymo replacing Uber.

by duped 2y ago
Waymo has zero presence in the vast majority of the United States and nowhere internationally. Meanwhile, "uber" is a verb and noun like Kleenex. And even if in ten years Waymo displaces Uber for transit, Uber will be dominant in

I agree with this but with a much more nuanced take: avoid pipes if either reader or writer expects to do async i/o and you don't own both the reader and writer. In fact if you ever set O_NONBLOCK on a pipe you need to be damn sur

Not necessarily, in fact one of the most important optimizations for compilers is inlining code (copy-pasting function bodies into call sites) which results in more code being generated (more space) but faster wallclock times (more speed).

This is what the `AsRef` trait is great for impl AsRef<str> for MyCoolString { fn as_ref(&self) -> &str { ... } } To be totally defensive, other library authors can write their APIs

Most of your target folder isn't debug info, but stale build artifacts because Cargo doesn't do any garbage collection.
