I think you have a specific class of race conditions in mind where tight control of the hardware is desirable or even possible. But what to do if you have a race condition in a database stored procedure? Or in a GUI rendering code? Even web

Yes, but to a lesser extent.

Assuming you meant C's printf, why would you subject yourself to the pain of recompilation every time you need to look at a different part of code? Isn't the debugger easier than adding printf and then recompiling?

by branko_d 1y ago
Well, if you have a race condition, the debugger is likely to change the timing and alter the race, possibly hiding it altogether. Race conditions is where print is often more useful than the debugger.

In my experience, coding is much faster when doing it this way. Yes, you can produce a small amount of code faster if you don’t “waste” your time on documentation, but that becomes counterproductive as soon as you can no longer keep the ent

Most other brands had very similar problems (including my trusty Nokia at the time). You can still attenuate antennae on modern phones if you hold it just right. It's just a matter of physics. Here is what Nokia N97 does when you &quot

Even if it's slower for the vast majority of cases, but there are rare cases where the computer would otherwise freeze, that's still a win.

There is a lot of value in explaining the gist of something, even if it's not entirely accurate. In my experience, the cases where even that is impossible are very rare, at least when it comes to practical computer programming.

The problem is not that the experts have dismissed vibe coding without even trying it. The problem is that the experts have tried it and found that vibe coding doesn't actually work at scale that they need. Will it ever? Perhaps, but I

And as a consequence, C# can pack the value types directly in the generic data structure, instead of holding references to heap-allocated objects. This is very important both for cache locality and for minimizing garbage collector pressure.

Probably because of the "D" in ACID transactions, so the transaction log cannot be meaningfully write-cached. OTOH, writing to tables/indexes is already done "out of order" and aggressively cached in the buffer pool

I would love to see Web platform become more similar to JVM or .NET CLR - just a bytecode JIT with access to rich layout/rendering engine. Then build whatever you want on top of it.
