Alex AngelUbuntu and other Linux variants do not have a Windows like CTRL + ALT + DEL screen, so I figured I'll make one myself. My plan is to make a HTML version, render that with the PyQt Web engine, and then when the keys CTRL + ALT + DEL are pressed the program launches. Preview it: https://codepen.io/...

pavelI'm trying to solve the LeetCode question where you need to find out the area of the container with the most water. I have created the solution that seems to work in my testing but it fails for being too slow when I try to submit it on LeetCode. My idea is that I create a dictionary of (x, y) tup...

Q: Pairwise summation

Pierre AbbatThis function adds up an array pairwise. It runs fast enough and appears cache-friendly; I've tested it for correct output. It's in C++ (farther down in the file there's a function that takes a vector), but looks like valid C as well (but I haven't tried it in C). How easy is it to understand? do...

From the cell (i,j) we can go (i,j-1), (i, j+1), (i-1, j), (i+...

When it comes to developing low latency software systems, the received wisdom is that you would be crazy to use anything but C++ because anything else has too high a latency. But I’m here to convince you of the opposite, counter-intuitive, almost heretical notion: that when it comes to achieving low latency in software systems, Java is better.

Q: N-dimensional array in Rust

apilatI am practicing Rust by creating data structures, such as this N-dimensional array. The purpose of this structure is to easily define and address into arbitrarily-deeply nested arrays without having to write out Vec<Vec<Vec<T>>> and incur the performance penalty coming from this (although perform...

@SimonForsberg Does @Duga have an endpoint anyone could do a "is live ping" to? Alternately do her endpoints support HEAD?

How am I asking many questions in one? The question is pretty focused. Make a method async and do the same thing automatically for the call stack. Also, what the tool does won't get merged without manual code review. It will save a lot of time. — user246392 46 secs ago

@Peilonrayz I think for now this is the best: stats.zomis.net/GithubHookSEChatService/registration/index (ignore the instructions)

If there's no message there by @Duga in > 2 hours, something is likely wrong
@SimonForsberg Thanks, may add an ability to 'health check' Duga, since my local server killed itself sometime last week and I was going to add a command to check for that.

If the code currently works as intended, and you're looking for peer review to improve it, your question should be asked on Code Review, which was created specifically for that purpose. You should make sure to read that site's guidelines in their help center to make sure it includes what is required there. — Ken White 16 secs ago
