Recently, I’ve bought a NetGear WNDR3300 router, which supports N-draft. Ffor a more convenient management of this router, I decided to put DD-WRT firmware on it. For some reason, however, my router doesn’t want to broadcast N-draft with this firmware. As information is limited, here’s how you can revert your installation of DD-WRT:

Although I’m Dutch, I prefer to use my Operating System and software in English. This has several reasons, but the foremost reason is that I just don’t like some translations (Mac OS X, for example, translates ‘File’ as ‘Archief’ (’Archive’) instead of ‘Bestand’ (’File’)).

Well here it is: The problem with safe trading at the internet is that you never know if your ordered product [...]

I noticed lately that there’s not much ‘webby’ about ‘webmail’. Webmail is just an interface for reading a POP- or IMAP-server. In fact, it’s just an idiotic construction from server to server to client.
Currently, e-mail uses POP3, IMAP and SMTP to communicate between client and server. This are, in my opinion, dated specifications (1982, 1985 [...]

I noticed that the CPU usage of Explorer, and to be more specific: the thread shlwapi.dll, could slow your system down quite a bit, especially if you’re computer isn’t quite state-of-the-art. That’s why I began my investigation.
It appears that shlwapi.dll is (among other things) the search engine for the Start-menu search bar. I personally use [...]

The best way for saving user data using PHP are Sessions. They come in different flavours: at first, there’s the one that makes your URL ugly, but makes them usable for all users. Secondly you can use cookies. That’s much nicer, but doesn’t work for all browsers. Surf2me.nl uses the latter.
