Auto clicker

This tool has helped a colleague find his partner for life on a dating site. This post is a little shady. To get students excited for creating software, i.e. a creative art, we can give them creative assignments. Aim This post shows how to automate the pressing of a button on a website. Why? Tinder just announced they’re going live with a web version. By showing students a case where they can ‘cheat’, could get them excited for more coding. Read more

So you want to become a hacker?

First lets get one thing straight. You have two groups, the angels and the daemons, white hat and black hat, hackers and crackers. Keep in mind, that the angels, the guys who find security holes and report them (what a sweet angel) are sometimes perceived as a daemon! The world is full of digital users, but the majority of people are ignorant fools when it comes to cyber security. For this reason, never call yourself a hacker, but a “Security researcher” or “Pen tester” (google it). Read more

The android phone for an iOS user

This is an old post, nowadays I would recommend We all know it, our phone is crappy and we want to upgrade it. For a lot of people this means a new iPhone, which I totally get, since the Android landscape is overwhelming. Of course BlackBerry and WindowsPhone are options, but since they have so little market share, you miss out on the good apps. TL;DR Buy a stock Android device, preferably a Nexus, or just get an iPhone. Read more

Scaleway C3

This is an old post, Scaleway does offer cheap 64bit VPSes now. Scaleway has a good deal with their ARM VPS. But there are some down sides.. One of them I have fixed (ufw). The other, getting to run docker on them, I have not tried to tackle. I’m currently satisfied, but may switch to OVH in the future, since their (same price) VPS has 64bit, which will run docker.

color inversion

This is an old post, nowadays I use a chromebook with a web IDE running on my server, which is set to dark theme. Some programmers use flux, which makes sense if you need to view pictures, but I prefer to invert the colors, system wide. Debian (ubuntu) sudo apt-get install xcalib and bind the following to your desired keyboard shortcut: xcalib -a -i #alter invert my current keyboard shortcut is SUPER (windows logo) + N (negative).

Forever 22

Let’s talk about something that can benefit our lives. No, not online clothes shopping, but SSH to your Linux VPS! If the last sentence contained two things you needed to Google, then this article isn’t for you (it all comes down to remote desktop, but fast). As a programmer, I see myself as an artist. Coding is a creative process for me, which results in making creative notes all the time. Read more

My favorite IDE

This is an old post, nowadays I use a web IDE. We all start with something like notepad++ until we start for something more useful. Various editors exist, Xcode with block scope highlighting (which is CPU intensive) to something like vim, which is ideal for quick editing of config files over SSH. My first real IDE My first language was Java, which was taught in BlueJ at my university (if your uni still does this, burn the books! Read more

Passwords, can you remember them all?

Old post, do not use this advice, but the tool found at As a logician, I like to order certain things in my life, based on logic, instead of emotion. Examples are file and directory structure, clothes in closet and of course, passwords. You probably all know the deal, of remembering various passwords, which can be a nightmare. And we all know that you should not use the same passwords on multiple site, because some save them plain text, and usually the sites that do, have poor security, which means an easy breach.

USB bike charger

Before the era of solar chargers, people could charge their phones via their bike dynamo. Phones back then charged at a maximum of 500mA, which is close to the 400mA a regular bike dynamo generates. Nowadays phones require lots more power. A video of this board can be found here. What you’ll need: 50x100mm board 4 diodes 1n5817 (in order of preference: 1n581[7,8,9] or 1n400[1,2]) large capacitor: 10-35v, 750-1000uf small capacitor: 10-35v, 10-24uf 7805 (don’t get the small 100mA) What you need to know: Read more
