(Student) rental house management platform

As my longest running project, the student rental house management platform has grown from a couple of pages to a portal that is still useful for, in this case my father, to manage his student house with 8 rooms. In this post I want to discuss the features, but also the components it’s built of. […]

3 nerdy things you can do with Telegram except chatting

You might know Telegram as a messaging app (like Messenger, WhatsApp, Wechat and the likes). Seen the increase in terrorist activity, it’s apparently also the preferred method for terrorists to communicate. But this can never be an argument against a free internet! Leaving politics aside: Telegram also has some very unique features, which will be […]

Displaying GDB dumped 802.15.4 buffer in WireShark

The 802.15.4 mac layer has these great headers with too many single-bit options; sufficient to make your head hurt after a while. Since I was debugging some code, I had access to the entire buffer containing the entire frame. It would be nice to show this in Wireshark, wouldn’t it? It’s actually not that difficult: […]

Debugging two targets with two Segger JLinks on Linux

How to solve Address Errors (on PIC24F)

Update Your compiler can help you out with some very common cause: the -Wcast-align flag. Every time you cast a value to something that was bigger than the previous one, you can get into serious problems. Prevent using any of these constructions… char *a_char_pointer; uint32_t *my_big_pointer = (uint32_t*) char_pointer; The a_char_pointer might be badly alligned […]

Configuring a Gyration remote to work with XBMC

This will be a quick post, mostly for future reference, but someone else might find a use for it too. Sources: The configs I found were made for a slightly different Gyration remote. Mine has colored small buttons on the bottom, while others have labeled black ones. I made some notes on […]

Encrypted Chatting

Have you ever wondered how safe it is to chat with MSN (nowadays Live) Messenger? Have you ever had a look at the traffic flying around a wireless access point? Well, you should! Install Wireshark on your computer and have a look at your own chat conversations. But for those of you who are simply […]
