I wanted to download youtube videos. So I got more acquainted with Apple’s user space scripting tools. Overall I’m pretty inspired by the clean UX of these tools. Of course, I guess all of these tools only work inside Apple’s walled garden, which is sad in terms of general population getting educated in general purpose …

Note: I can attest this to be functional for me, but I’ve used an LLM to produce this. Your mileage may vary. Please check your particular details, particularly the call for checking temperature may vary. Many people have video files that no longer work on modern devices. You may have downloaded or perhaps made backups …

I tend to always forget how to use prepared statements, so I generated this little helper function that always does what I typically want. (TODO: retest this, 2023-09-04) #include <QSqlQuery>#include <QSqlError>#include <QVariant>#include <QMap>#include <QDebug>#include <QSqlDatabase>/** * Executes an SQL query with placeholders. * * @param sqlString The SQL query string with placeholders. * @param placeholderMap …

In my layout, my dynamically generated QTableViews seem to get resized to only show one row. I want to have the container of the table views to have a scrollbar instead of the individual table views, which should show full contents. Qt doesn’t have anything built in for this apparently, you need to calculate and …

I finally got sick and tired of all my windows laptops breaking physically one way or another. First there was ThinkPad Edge, then there was the ultrathin Sony Vaio (bought just before Sony sold the business and discontinued the thing). Developers, Linus Torvalds included, online seemed to agree that MacBooks are the best hardware on …

Where an expert might think something is simple, the student’s journey toward understanding is filled with twists and turns the expert no longer even remembers. This is really the core challenge of teaching: how to communicate the complex when your own mind has already largely automated those early …
Authors: Olli Savolainen and Daniel Schildt Olli: In my opinion, it is important in the teaching of programming fundamentals to focus on the essential: Learning what will help you get started quickly and implement your own ideas. This is particularly challenging with C and C++ languages, teaching of which is sometimes still needed. When a …

For unit testing, I needed to read ForceProof project database into an in-memory SQLite database, from a .sql text file. Turns out, Sqlite (at least in Qt) is unable to execute multiple statements in one string.
