JavaScript gives us a built-in language feature for handling exceptions: try…catch statements. And they’re better than littering our code with if-statements. But they can be problematic. And they are not the only way to handle errors. In this article, we’ll take a look at using the ‘Either monad’ as an alternative to…
Not the entire thing, just "a subset". It's not stated very clearly exactly what that subset is but the easy interface is mentioned in the Chrome bug about this project. What? The Chromium bug states that they will create a library of their own (named libcrurl) that will offer (parts of) the libcurl API and … Continue…
tldr; saw a Windows Calculator bug on reddit . Since calc.exe was open-sourced I thought I’d try to find the bug and fix it. Cloned the code, recreated the bug, and found a minimal fix .
I’ve seen the inside of the Google and Amazon tech stacks. There are common threads that run through them and also, I bet, through most BigTechCos. Here and there down the stack is a lot of C++ and vestigial remnants from earlier days, Perl or PHP or whatever. Out in front of humans, of course, JS. But in between…
Or rather, an object is a set of functions that operate on implied data elements.
Simon Ritter, Deputy CTO of Azul, covers evolutions in Java including, 6-month release cycle, a change to the switch expression in JDK 13 and more.
In this step-by-step tutorial, you'll get a clearer understanding of Python's object model and learn why pointers don't really exist in Python. You'll also cover ways to simulate pointers in Python without the memory-management nightmare.
Coding puzzles and their prevalence
During my final term at UWaterloo I took the CS444 compilers class with a project to write a compiler from a substantial subset of Java to x86, in teams of up to three people with a language of the group’s choice. This was a rare opportunity to compare implementations of large programs that all did the same thing…
Real world example where uniform syntax enables unthinkable solution
A collection of examples of how to use Common Lisp
Hello! It looks like you're writing a blog post - would you like help with that? chuckles Me and my colleagues at Microsoft have decided that the world needs more Clippy - the adorable animated paperclip. To help with that, we're bringing a new feature to Edge 6.0. Web Developers can now use <clippy> to call up an…
This post describes the C++ Badge template used to enhance member function access control in Serenity Operating System.
I like Python, but wish it had static typing. The added safety would go a long way to improving quality and reducing development time. So today I tried to make use of type annotations and a static type-checker called mypy. After a few basic tests, I was excited. But my glee turned to disappointment rather […]
How do you design good abstractions? By using abstractions that already exist.
Reproducibility is an essential requirement for many fields of research including those based on machine learning techniques. However, many machine learning publications are either not reproducible or are difficult to...
How to split up your large, complex, frontend codebases into simple, composable, independently deliverable apps.
23114, 584, 46931, these three numbers were used to create the entire universe for Elite .
Most programming languages evolved awkwardly during the transition from ASCII to 16-bit UCS-2 to full Unicode. They contain internationalization features that often aren’t portable or don’t suffice.
Here’s a fun bit of trivia: malloc on Linux never fails [due to the obvious cause]. In this post, we’ll show that this indeed is the case, and explore why…
