Today I had problems running my newly installed cygwin 1.7 beta and minTTY after updating BitDefender. It only took me some minutes to find out that BitDefender was the cause of the problem (much faster than the last time).

Currently we are developing the connection to mPAY to handle payments for our online time tracking application timr.com. mPAY provides a https URL that takes the payment parameters and returns if the transaction was successful.

I am using jungledisk for about half a year now to backup my Ubuntu home server online (photos, mp3, …). Today I tried to configure the virtual server this blog is running on to backup my blog with jungledisk – but I had no luck. Jungledisk uses fuse to mount the web service storage and [...]

Some months ago I wrote this post about Setting up subversion on Debian etch. I mentioned that you could use the AuthzSVNAccessFile directive to add more detailed access control for your subversion repositories. That time I did not need it and I did not look into the detailed documentation. Today I needed to setup another [...]

I am running my own mail server now for over five years. There are a lot of good free email services out there but I am not satisfied with their spam filters. I am getting about 300 spam mails a day and with my current solution only one of them makes it into my inbox [...]

This can be quite frustrating if you are a power user and you are used to your shortcuts and tools. Here are some tips to get rid of useless limitations some system administrators may have configured to your [...]

Today a version of KeePass was released that works on BlackBerry devices. KeePass is a free, OpenSource password manager. It comes with a desktop client and (thats the best part) can be synchronized with the BlackBerry. I am currently using MiniSafe Desktop which I purchased two years ago for 29 USD from Handango. I am [...]
