Configure Heli-X RC Heli Simulator with USB trainer for the Spektrum DX6i in OSX and Windows

Spectrum DX6i
Spectrum DX6i

I recently bought the Spektrum DX6i remote for RC planes and helicopters. To avoid damaging my RC helicopter on the first flight, I decided to practice on the computer first. There is a cross platform RC simulator called Heli-X which works on Windows and OSX. With Heli-X you can fly helicopters and quadcopters. I use the demo version since the time limit of 10 minutes is enough.

Syncing multiple and delegated Google calendars with iPhone / iPad

Syncing multiple and delegated Google calendars with iPhone / iPad

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.

Connect to internet with BlackBerry simulator

Connect to internet with BlackBerry simulator

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.

 

Server monitoring using Munin

Server monitoring using Munin

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.

Backup Flickr account to harddisk in OSX and Windows

Backup Flickr account to harddisk in OSX and Windows

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).
