I was looking for a smoother Munin theme and found this one. This theme has a cleaner design than the default Munin theme and comes with an icon for the iOS springboard.

I have several delegated calendars setup in my Google account. Unfortunately my iPad only syncs with my primary calendar and there is no way to select my delegated calendars. Then I found this page. Which describes how to solve this problem. The answer is simple just visit https://www.google.com/calendar/iphoneselect and check the calendars you want to sync. Restart the calendar app and all calendars are synced. You might have to check them in the view options when they do not show up.

When I used the BlackBerry simulator I was unable to connect to internet from the build-in browser. In order to enable internet access, follow the steps below.

BB menu -> Manage Connections -> Setup Wifi network

The wifi wizard starts.

Choose Next ->Manually Add Network

Enter “Default WLAN Network” as SSID and choose Add

Choose “No security” and pick Connect

Pick Save (do not choose for connect, since this fails).

Pick Next

Done!

Update 16-05-2011:
It turns out that the method described above also works when a BlackBerry prompts for a PIN code in an open network. Just enter the name (SSID) of the open network as the network name and your BlackBerry can connect to an open network without entering a PIN code.

Munin is a networked server monitoring tool written in Perl. Munin consists of two parts: the Munin server and Munin nodes. The nodes are running on the servers we want to monitor, while the server periodically (5 minutes by default) fetches the data from all of the registered nodes. The server is a able to build charts from this node data, which gives insight in the cpu usage, disk usage, network load and more.

The Munin team has a live demo of Munin, which can be viewed at http://munin.ping.uio.no/ I have installed both the Munin node and server on my Ubuntu server machine, and added nodes of other servers as well.

I upload a lot of pictures to Flickr. I was looking for a tool to backup all the pictures I have uploaded during the year. Although there are several tools available, only one succeeded in downloading my entire collection (about 500 photos) without any problems. I tried a python tool, which had a crash during downloading. Antoher Java tool failed as well. Finally I tried Bulckr, which is an Adobe Air tool. It works pretty straightforward and downloaded all the pictures with only one timeout (which it detects and let you resume your download by clicking a button).

My new Mac Pro had a strange problem. When I turned on the Mac or woke it up from sleep it had no ip anymore. The only way to fix this problem was to switch the cable from ethernet 1 to ethernet 2. Sometimes I had to repeat this step, turn wireless on and off and finally I got an ip. When I restarted the router I did not have to switch the cables, then I got an ip immediately after the restart.

I searched on the internet and found several solutions:

• Reset PRAM
• Remove and add the ethernet connections
• Check the cable (the cable worked for years on my MacBook Pro)
• Try different ports on your router

None of these succeeded. I decided to contact Apple within a few days but first I searched again on the Internet. I found this page which described exactly my problem. The interesting part of this thread was about the FritzBox since I do have this router as well. The thread suggested to disable energy saving mode on the ethernet ports of the router. Which turned out to be the solution! Now my network is immediately connected after a reboot or wakeup.

Every time I reboot my Mac Pro the sound output resets itself to internal speakers. This is quite annoying and I had no clue how to fix it. This topic on the Apple forums shows how to fix it.

First delete the audio preference folder:

$ sudo rm -r /Library/Preferences/Audio

Recreate a new one:

$ sudo mkdir /Library/Preferences/Audio

Change the permissions:

$ sudo chown -R _coreaudiod:admin /Library/Preferences/Audio

Go back to the sound preference panel and set the audio to the one you prefer. This will recreate the settings file.

Reboot the system and see if it works.

I accidentally formatted my external harddisk in OSX. Since I wanted this disk to be NTFS I needed it to be formatted in Windows. When I opened up disk management I was unable to format the harddisk because it had a GPT protected partition on it.
