I really like this App ScreenFeeder, but currently it does only restart with a crash.
Here is the crash log and console output.
Update: Deleting the app and directly reinstalling it solved the problem, it even kept my accounts.
I just found this wonderful physics simulator. It is not even fun for my kids it also enjoyed me for the weekend. You find it in the Mac App Store.

With the transition from MobileMe to iCloud some valued service are dropped. The one I’ll miss the most is the keychain sync between all the machines. That frankly was the reason in the first place, why I bought MobileMe. But a good friend of mine felt the same pain and created a perfect replacement, which is called Keychain2Go.
Here is what I’ll have on my iPhone this month.

Since 10.7.2 it is possible not only find my iPhone, but also to find my Mac. I’ve added all of them to the iCloud service and used the sosumi php scripts to get the data.
Since today the iCloud is available to the public and you can use it to find your iPhone. The location service I described also works with iCloud accounts.

This is part 3 of the DIY Location mapping. This time we will integrate with google earth to see live updates from our devices, we tracked with part 1.
Therefore I have had the tracking running for some days with an update interval of 15 minutes, so that I does not drain my battery too much. By enhancing the update frequency you will get fine grained location data.
We need to add the following PHP script to deliver a valid KML file, which is loaded by another KML file. The second KML file is loaded into Google Earth and does poll data via the PHP scripts to enable the live updates. Continue reading
The godfather of C and Unix died.
Thanks for all you left.
“Unix is simple and coherent, but it takes a genius – or at any rate a programmer – to understand and appreciate the simplicity.”
“The greatest danger to good computer science research today may be excessive relevance. If we can keep alive enough openess to new ideas, enough freedom of communication, enough patience to allow the novel to prosper, it will remain possible for a future Ken Thompson to find a little-used Cray/1 computer and fashion a system as creative, and as influential, as Unix.”
Just moved from macports to brew.

Map Example
After the data collection part 1 we now want to display the collected data on a map. We use the google maps API to do so.
You need to have an API key for it, which you get at http://code.google.com/apis/maps/signup.html. Continue reading
Location based services needs to be switched on
Inspired by the question in the http://fanbóys.org/ podcast, I will write down, what I have up and running for over two years now.
Goal: Have a background method running, which collects your location during the day and displays it on a map and has some export functionality.
Ingredients: An Apple iPhone, an Apple ID, activated Find My iPhone, a LAMP system and additional Google Maps. Continue reading
Just|Mobile Gum Plus Power Pack
Just got my hands on this little beauty. Charges via MiniUSB and delivers power via USB port to charge your iPhone or Mifi or whatever needs to be charged.
It does charge your iPhone4 up to three times. The 4400mAh capacity is delivered as 1000 mA.
The power pack comes with iPhone charging cable, USB charging cable and a nifty carrying pouch.
The access to an access limit folder by the AFP is not possible. Time Machine backup is not possible
Firmware update for improvement is planned.
My workaround is to mount it via SMB.

[Update 2] Here is a workaround on the support pages from Apple.
Lion and Lion Server maintains a list of authentication methods that are not allowed. These are the older, less secure authentication methods. You may need to enable one or more of these methods to support legacy devices or protocols.
- Open Terminal.
- Execute the following commands:
sudo chmod o+w /Library/Preferences sudo defaults write /Library/Preferences/com.apple.AppleShareClient afp_host_prefs_version -int 1
- Restart the computer.
- For an AFP connection, on the client make an AFP connection to another system so that the AFP Client preference file will be filled in with the default set of values.If you want to enable a different User Authentication Method (UAM), execute the apprpriate Terminal command on the client system. For example, this command enables DHCAST128 by removing it from the list of disabled methods:
sudo defaults write /Library/Preferences/com.apple.AppleShareClient afp_disabled_uams -array "Cleartxt Passwrd" "MS2.0" "2-Way Randnum exchange"
To see a list of the disabled User Authentication Methods (UAM), run the following command in Terminal on the client:
defaults read /Library/Preferences/com.apple.AppleShareClient afp_disabled_uams
Typically, the disabled UAMs are “Cleartxt Passwrd”, “MS2.0″, “2-Way Randnum exchange”, and DHCAST128.
To enable one of these UAMs, the list of disallowed methods needs to not list the UAM that you want to exclude.
[Update3] Buffalo released some beta firmware updates. See Compatible devices
Just found DAViCAL and will have a look into this soon.
This little awk snippet wraps textlines longer than 80 characters and prepends a single blank to the wrapped content.

while (i< =textlength) { { print " " substr($0,i*70+1,70) } i=i+1} \

The idea of behind the way multitasking is handle in iOS, is to keep the battery life in a good shape and just keep the tcp sockets so far connected to wake the application, when something is happening on the connection.
The most VoIP application are using SIP, which is normally running on udp. And udp is not available for backgrounded application. So you might also get SIP via tcp, which has it‘s own merits and caveats.
SIP uses udp for the low latency and jitter purpose. It usually is okay for a listener, if some of the packets never made it to you and are dropped. We are all used to bad lines, we do not rely on perfect transmission. Means, it‘s fine to get crystal clear lines, but we also understand the opposite, if the drops are below a certain limit. udp is just build for that purpose.
Tcp on the other hand does retransmit packets until they reached the target, even if it has to stop the transmitting until this one piece of information has travelled. So with sip over tcp, the problem is not that we hear a bad line, but we could hear paused conversation, like stop and go on the highway.
If these stops getting above a level, our communication breaks down.
Technically there are some ways around this problem.
Hi,
this is an update to my previous entry, and does explain the architecture and all the steps you’ll need to set it up.
We make use of the pptp capabilities of iOS and build an pptp tunnel to a fixed server @.
From there we have an openvpn tunnel to our asterisk box *, which has ISDN links to the PSTN.
Routing makes shure, that all SIP traffic is shoveled between the endpoints.
Voilà encrypted calls, with your favourite SIP app.

rsync does a fantastic job to sync and keep in sync content from one to another system. Backups are perfect with it, use rsnapshot to get even more out of it.
But rsync is not good in bi-directional syncing in the case of deletion of content. Despite, that you can delete all file on all content directories on all hosts, which is not an option for a the very-day user.
Keep in mind, that you need same timezones and synced clocks, when using the –update option
Look out to keep things in sync, with deletion too, take “unison” for example.
