Dictaat Linux

Afgelopen kwartaal heb ik, samen met Kevin van der Vlist het keuzevak Linux gedoceerd om de Hoge School Rotterdam.
Voor dit vak hebben wij speciaal een dictaat Linux geschreven welke de basis van Linux behandeld en de student leert omgaan met de basis van Linux.

Het dictaat is te vinden op http://www.hosthuis.nl/linux/ en kan vrij gebruikt worden onder de GPLv3.

De source files zijn ook online beschikbaar, en staan op https://github.com/kevinvandervlist/tirlnx01

Android and JSON

This afternoon I needed to create a JSON string in Android. Trying to search this at google I found nearly no results, except for reading/parseing a JSON string. I didnt need that (yet), I just needed to serialize/create a JSON string. At the end I came up with the next class to generate a basic JSON string, and to use it to post to a website.

The class includes a method that returns a HttpEntity, that can be directly used to send to a website via HttpPost.

Fun things you can do with android

Now I bought last week a new phone, with android  2.1 iam kinda having fun with it. As a school project our project is currently to program for android (Whats not that difficult, it basicly is java :) )

after playing a bit around with the SDK for android, I discovered a function that you can use to make a screenshot via the computer at your phone. (If you dont know how, its pretty easy. But I will post a bit more explained how later as seperate post).

Now the more weird thing, after some minutes playing around with this function, the phone was gone into sleep modes. So I expect if the phone is asleep, the screen is just black when I make a screenshot. However, it isnt, see the attached screenshot (Iam afraid you will need to trust me that thats the actual screen being displayed, I know :P ).

Something about servers, moving sites, and greylisting as anti spam

I never wrote a lot about the few servers I manage already for some time. Since half November there was a brand new server for hosthuis.nl to replace mostly the current server.
The current server is a nearly 3 year old box, that hosts several pretty well known sites, like www.phpbb3styles.net and www.phpbbmodders.net, besides the own sites from hosthuis.nl. Read more »

Moved blog

I just moved this blog to a brand new server, hopefully everything is still working (And I still have email etc :D ), if you notice a error, please report it to me :)
