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.
Runkeeper is a great tool to track your running and cycling. I was wondering, if I wanted to quit Runkeeper one day will I be able to export my Runkeeper activity data? There are scripts around to do so, but it turned out Runkeeper offers a way to export your data as GPX files. Here is how:
I was looking for a solution to connect my Android smartphone and iPad to a PPTP VPN. I found this tutorial by Marthijn van den Heuvel which explained step-by-step how to setup this VPN on Ubuntu server.
The wp-syntax plugin is very useful. Unfortunately the wp-syntax plugin does not support the processing language which is used for Arduino programming. This website offers the arduino.php file for the wp-syntax plugin. Simple upload the arduino.php file to the wp-content/plugins/wp-syntax/geshi/geshi folder.
Calculator Easy HD is a free calculator app for the iPhone and iPad which also lists your previous calculations.
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).
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).
