I have done multiple changes, but the moment I get an event on a game controller, it'll lock up until a new event is made on the game controller. I cannot find any documentation on what to do exactly, only some vague gesturing about EV_SYN events, and that they should be handled in a certain way. And of course the usual recommendations of "but there are already libraries made to abstract OS-level stuff", except many of them often janky in more than one way (a lot of them still uses DirectInput).

Wrote this to reduce boilerplate when calling a function with a nullable parameter. Language is Dart. I like how concise it is but it feels weird to override []. Would you be okay with this?

extension CallMaybe<R, T> on R Function(T t) {  
  R? callMaybe(T? t) => switch (t) {  
    null => null,  
    T t => this(t),  
  };  

  R? operator [](T? t) => callMaybe(t);  
}  

void example() {  
  int? n;  
  math.sqrt[n];  
}  

Please excuse - and do not hesitate to point out - any violation against etiquette that I might be committing here... I am new here.

I started to learn C a few months ago as a hobby as part of a bigger project, namely to learn about computers in general. I have had so much fun reading Code - The Hidden Language of Computer Hardware and Software by Charles Petzold. But that's another story...

I was about to buy a few new SSDs and needed to do some budgeting. Instead of using my phone's calculator, I decided to try to write a calculating program in C, because I hadn't touched programming for some weeks or months because life and I wanted to see if my knowledge had matured some.

The goal was to have it do the four standard arithmetics and also save the last result in a variable, which I just called "memory" for lack of bette phrasing on my part. Maybe next week I'll figure out how to make it possible to use the value saved in memory instead of having to type a number.

I welcome any constructive criticism on how and why this code is up to code or not(sorry...), if it can be improved and how or even if it's just garbage and why that is. I am just proud that it worked without gcc throwing any errors.

#include <stdio.h>

int main(void) {

        int num1 = 0;
        int num2 = 0;
        int choice = 0;
        int memory = 0;

        printf("Welcome to the Calculator of the century!\n\n");

        while (1) {
                printf("What would you like to do?\n\n");
                printf("(1) Add two numbers\n(2) Subtract two numbers\n(3) Multiply two numbers\n(4) Divide two numbers\n(5) Show memory\n(6) Exit\n\n");
                printf("Enter 1, 2, 3, 4, 5 or 6: ");
                scanf("%d", &choice);

                if (choice >= 6 || choice < 1) break;

                if (choice == 5) {
                        printf("\n%d in memory.\n\n", memory);
                } else if (choice < 5 || choice > 0) {
                        printf("\nEnter the first number: ");
                        scanf("%d", &num1);
                        printf("Enter the second number: ");
                        scanf("%d", &num2);
                }

                if (choice == 1) {
                        printf("\nThe sum of %d and %d is %d\n\n", num1, num2, num1 + num2);
                        memory = num1 + num2;
                } else if (choice == 2) {
                        printf("\nThe difference of %d and %d is %d\n\n", num1, num2, num1 - num2);
                        memory = num1 - num2;
                } else if (choice == 3) {
                        printf("\nThe product of %d and %d is %d\n\n", num1, num2, num1 * num2);
                        memory = num1 * num2;
                } else if (choice == 4) {
                        printf("\nThe quotient of %d and %d is %d\n\n", num1, num2, num1 / num2);
                        memory = num1 / num2;
                }
        }

        printf("\nWe hope to see you soon again!\n");
        return 0;
}

During OpenAI’s GPT-5 launch event, they demoed the model’s ability to fix real bugs in production code. Live on stage. In their own repository. The kind of demo that makes CTOs reach for their credit cards and engineers nervously update their resumes. There’s just one small problem: the fix they promised to merge “right after the show” is still sitting there, unmerged, three and a half months later.

I’m trying to convert a blog into an EPUB and keep running into issues with existing tools.

I first tried blog2epub, but it fails during parsing with:

lxml.etree.XMLSyntaxError: Opening and ending tag mismatch: meta line 10 and head, line 17, column 8

I then tried WebToEpub on Firefox, providing:

• Content selector: .article-content
• Chapter title selector: .title

It generated an EPUB, but the file wouldn’t open in any reader.

What I’m looking for is a tool where I can point to a blog’s base URL, define CSS selectors for the article title and body, and have it automatically fetch all entries and create one chapter per post. Or something similar.

Does anyone know of a reliable tool, script, or workflow that does this well on Linux?

Devs gripe about having AI shoved down their throats

A couple of weeks ago, I made this post over at !asklemmy@lemmy.world asking if I should go back to university. After some thoughtful consideration, I've decided to pursue certs; specifically Comptia A+ and then the Network+. I'm almost done with an A+ study guide I bought and feel almost ready to take the exam. But I've also wanted to hear about your experience on getting tech certs and the career that followed. Any advice is welcomed. Thanks in advance.

I am baffled any time I'm on facebook how horrid it is. Loads insanely slowly, won't accept picture uploads at random, randomly doesn't let you share to people in your friends group (it will just hide people for no reason). Such a terrible website. Sadly I have to stay on it for friends and music reasons (there is nothing else anyone I know uses) but man, it's crazy how badly they want you to install their spyware app so you don't use the browser version.

I have a vendor that sucks donkey balls. Their systems break often. An endpoint we rely on will start returning [] and take months to fix. They'll change a data label in their backend and not notice that it flows into all of their filters and stuff.

I have some alerts when my consumers break, but I think I'd like something more direct. What's the best way to monitor an external API?

I'm imagining some very basic ML that can pop up and tell me that something has changed, like there are more hosts or categories or whatever than usual, that a structure has gone blank or is missing, that some field has gone to 0 or null across the structure. Heck, that a field name has changed.

Is the best way to basically write tests for everything I can think of, and add more as things break, or is there a better tool? I see API monitoring tools but they are for calculating availability for your own APIs, not for enforcing someone else's!
