To pull backups, the backup system connects to the production system and grabs the data, storing it locally on the backup system. To push backups would be for the production system to connect to the backup system and send the data. The main

They can be made to work by introducing stubs for every os/arch/compiler/dependency I support, but that's way more work for dubious gain. And who is to say I'm doing it wrong? Just because conditional compilation CA

> Conditional compilation is an optimization, not a semantic intent. Why can't it have semantic intent? I frequently use it for cross-platform adjustments, and those don't usually compile on the defined-away platform.

In my opinion this is way too much gate keeping. Who defines which tools are "basic tools of the trade" and which are just bland infrastructure? And who decides how much of each tool one should know to move beyond "daily inco

"max" seems like an odd choice. Wouldn't that start to fail at large numbers? Edit: Nevermind, max is lexicographic, not based on string length. Brain fart.

It's all anecdotal. For example I know many folks who make $$$ doing the boring old thing because it is reliable, it gets results quickly with low risk, the engineers know the tech inside and out, and not many other folks want to work

The two are orthogonal. Even with generics, languages can have an "escape" type like interface{} which is used/necessary for when you do want (or require) run-time type checking.

wikibob was probably looking more for public documentation about the why and how rather than confirmation that the statement is true.

Can anyone with some real experience with this comment on the debug visibility? In gdb or lldb or otherwise? How easy is it to see what is going on, partially expand macros, get at intermediate values, or evaluate things at the debug prompt

From all of the horror stories I've heard, it is not foolproof. For one, don't you get notified after the usage and charge happens? So one mistake that causes a large spike and the notification is too late.

The problem is, UB is not guaranteed to segfault. A guaranteed segfault when a bug is hit would be great - but randomly getting one of (segfault, silent memory corruption, invalid instructions, ...) is not great, and most people would consi

NixOS probably helps with this, but it isn't a requirement - some devices already have a dual-root-type setup where they update the inactive root, boot into it, and the boot sequence doesn't mark it permanently active until it boo

The personal freedom to make choices for one's self should absolutely be up to the individual - but only insofar as those choices only affect the individual making them. Once you talk about things like being contagious and infecting ot

In that case, of course, the method of finding where the script lives would return something that indicates there is no script. But also in that case, the commands you are piping into the shell probably are not looking for the files they we

I feel like this is only a problem if the small functions share a lot of global state. If each one acts upon its arguments and returns values without side effects, ordering is much less of an issue IMO.

This is not correct. "Structuring" has a specific meaning and transferring $9,000 (or any other amount under $10,000) is not enough on its own.

The waitpid() call isn't quite as broken; I think there are only races there if there is any chance other parts of your process call waitpid() on the same pid and it gets reaped twice. Under normal operation (pid returned from fork, wa

I'm having trouble contrasting that to the many ways I can add 2 and 3, and this doesn't bother me: x = 2 + 3 x = 3 + 2 x = (2 + 3) x = (3 + 2) x = 2; x += 3 x = 3; x += 2 x = 2; x = x + 3 x = 3;

In javascript, what prevents the body of the map function from doing arbitrary stuff? Don't you have to read that to know for sure, just like a for loop? In some languages the map function may be restricted to not have side effects, in

The main difference is your mortgage was likely acquired long before the value reached that level. The choice was never between renting and buying a $1m home for a $500/mo difference.

The comment author may think there was no reason but almost every time I see a comment complaining about being downvoted, I see a reason among those I listed above.
