PHP: how did it become so popular?

PHP empowers a gigantic part of the internet. So it is, by definition, a very popular (i.e. prevalent) language. But it also very popular (i.e. well-liked) to dislike PHP as a — serious — language. This could be explained as one of the side effects of that same popularity. With great exposure, comes greater scrutiny. […]

Git is eating the world

The inception of Git (2005) is more or less the halfway point between the inception of Linux (1991) and today (2019). A lot has happened since. One thing is clear however: software is eating the world and Git is the fork with which it is being eaten. (Yes, pun intended). Linux and Git In 2005, […]

Gid – Get it done!

Last weekend I built a personal ToDo app. Partly as an excuse to mess around a bit with all this ‘new and hip’ Web 2.0 technology (jQuery and Bootstrap) 🙈 But mostly because I needed one, and I couldn’t find a decent one. Decent? Decent in my opinion would be: Self hosted Self contained Use […]

Create a Chrome bookmark html file to import list of URLs

I recently switched RSS providers and I could only extract my saved posts as a list of URLs. So I thought I’d add these to a bookmark folder in Chrome. However, Chrome bookmark import only accepts a specifically formatted .html file. So if you have a file with all your urls, name this file ‘url.txt’ […]

And this happened after a server or website migration. You exported your database and imported this export or dump on the new server. And now your posts look like […]

Use PostgreSQL REPLACE() to replace dots with commas (dollar to euro)

If you have set up your database tables correctly you might be using double-precision floating numbers to store currency values. This works great because dollars use dots to represent decimals. The problem starts when it’s not actually dollars you are storing but euros, and maybe you need to copy query output to Excel or LibreOffice […]

Can we replace paper?

Paper always beats rock and scissors. Because one of the few inventions greater than writing itself, is writing on paper. Paper writings are absolute, self-contained and transferable units of knowledge, which after publishing become and stay available and accessible for hundreds of years or more. Don’t take my word for it, there is this great […]

Save data from your broken Raspberry Pi SD card with GNU ddrescue

This week my Pi stopped working. After hooking up a monitor I saw kernel errors related to VFS. So the file system was obviously broken. Oops. The end conclusion is that the SD card is physically ‘broken’, but I still managed to salvage my data — which is more important than the card. Here’s how. […]
