Is this a joke? Systems programming is a lot about accessing APIs, dealing with all sorts of intricacies like interrupts, different execution contexts, and managing memory as you said. If you write in C and your program is complex enough, y

You mean, manipulating strings of bytes? Bytes don't have to be memory, you can just use bytestrings in Python or whatever. Raw memory access is something you normally need to create vulnerabilities, not to exploit them :)

> Defenders of C/C++ frequently note that memory safety bugs aren't a significant percentage of the total bug count, and argue that this means it's not worth the hassle This says more about those C++ defenders.

Alpine base rootfs is just a few megabytes, while Arch is like 100-200MB. I usually encounter Alpine in Docker containers when people want to wrap just one specific service and have save space on things that are not essential for it (it wou

It works fine, unless you want to use Google Calendar and a non-Gmail email together. Then it goes nuts and makes your Gmail send out calendar invites instead of the email you use.

Sorry, I indeed switched to a wrong browser tab and skimmed instead of reading when started this discussion. Please disregard the quicksort discussion. I still think that it's normal for programs to behave weird when the input paramete

by gnull 4y ago
No, wait. The QuickSort from the article is O(n²), in fact. So that one specifically will take weeks, or even months to run — especially in Java. Feel free to test it and get back to me if you think I'm wrong.

by gnull 4y ago
Ok, I looked at it closer and I admit that quicksort implemented in C won't take days on an input of 2³¹ elements. It will take less than 1-2 hours, I think. Something that is a bit worse than O(n log n) or has a 20× bigger constant hi

My main takeaway from this is that the seemingly contradictory notions like "mutual help" and "competition" are just too vaguely defined, and exist on a wrong level of abstractions, to have any formal discussion about th

"High" as in "higher than runtime speed, safety, abstractions, plugin system"? Where would you put it if you had to rank compilation speed with other criteria? And let's admit even though Rust compilation speed coul

You misread my comment. I didn't say it was useless, I said there are things with higher priority. And well… unlike Rust, C++ sucked at some of those things too, this I think makes them different. Rust offers a better trade-off between

by gnull 4y ago
It's a fair remark, but your requirement is very niche. There's very few people who will value compilation time over runtime speed, safety, good abstractions, expressiveness.

Your example has nothing to do with geometry, it's incomputable because of encoding you use for real numbers. There isn't anything special about diagonal line that makes it incomputable. I only skimmed the linked article very quic
