NightCap for iOS


I just wanted to briefly share my first experience with an app called NightCap which promises to take better pictures in low-light situations than the standard iOS Camera-App through the longer exposure time it uses to take them.

Here you can see a picture taken with the standard app for taking photos at almost night-time:


And here’s a picture taken under the same conditions using NightCap:


Looking at this light source in the upper right of the pictures it seems obvious that this single-purpose app wont be suitable for use in normal, let alone sunlighted situations because the app makes light sources look much brighter than they really are but overall the second picture seems far more usable than the first one, especially considering that these pictures have been taken with the rather crappy rear-camera of an iPad 2.

QR-Code Generator


I have just found something for all you Tech-Freaks out there who are always trying to keep up with the latest mobile technologies and trends. While we might all use QR-Codes in combination with our phones from time to time, the possibility to generate them yourself is new to me.

So I present you the QR-Code Generator:

This Website can turn URLs, Texts, Phone Numbers and SMS Messages into QR-Codes of 4 different sizes so you can share them with others and make it easier to get your content out to mobile phone users.

What we have come down to.


Some dark days are ahead of us my friends.

As I have now already read from multiple sources the US Federal Communications Commission (or FCC) has recently passed what many Enthusiasts fearfully call the Net Neutrality Act. For those of you who don’t know what this is:

Network Neutrality is the basic principle that describes the access to a network (on the Internet) for all of its users as being neutral. It indicates that everyone has the same Level of Access to a certain Network’s Contents. That nothing gets Priority over something else or is taken out entirely.

This principle has hereby been broken for Users accessing the Internet over Cellular Networks in the U.S.A. From now on, Providers can help themselves to a better Quality of Service by for example downgrading the priority of Skype Traffic or even charging extra Money for it. While it is true that Skype Phonecalls aside other things use a lot of traffic and are therefore a Bandwidth-Killer for Celltowers I simply can’t believe this is seen as the Solution. If the Structure of a Network gives in to the Demands of its Users the Provider has to make sure that the Structure is improved in my Eyes.

This Article from Dial-A-Phone sums up the basic Problem of this Approach even further. The Net Neutrality Act allegedly doesn’t even restrict the Providers from shutting down certain Services entirely.

Some dark days are ahead of us my friends.

Sick and twisted fruit


To scratch the topic of Mobile Computing once again I want to take you through the processes of setting up an iPhone and a Nokia N97 Mini with a Bluetooth driven wireless Keyboard. The reason I’m doing this is of course due to recent events I experienced and – SPOILER ALERT – the iPhone fails miserably under almost all circumstances. Successful ones could unfortunately not be tested.

The Keyboard used can be seen on the following picture, accompanied by the successfully paired N97 Mini:


Why it’s a Bluetooth Keyboard designed by Apple themselves, just to make it a little less tough for the iPhone one might think. But I digress.

The step-by-step Instructions for the N97 Mini (or basically any Symbian S60 device) go as follows:

  1. Download the free Bluetooth Keyboard Application from Choosing the right one shouldn’t be too hard, I didn’t find one for Symbian S60 5th Edition so i just took the first one which popped up an incompatibility alert but still installed and worked fine.
  2. After opening said Application, turn on your Keyboard and pair it with the Phone. In my case this included defining a Passkey like “123456” and then entering exactly that Passkey on the Keyboard. Pressing Return should finish the pairing process. I assume this works the same on all Bluetooth enabled Keyboards.
  3. That’s it. You’re set to write some text messages or even emails with your Bluetooth Keyboard.

On the iPhone on the other hand, the situation looks as follows. (At least that’s all I found out on a jailbroken iPhone 3G with the latest jailbreakable iPhone OS 3 on it).
When you turn on Bluetooth and search for devices, the (Apple !!) Keyboard does not show up. So if I’m not wrong that takes care of our first approach. The second approach then would be taking advantage of the freedom of a jailbroken iPhone. Do some searching on Google/Youtube and what I found was a Video explaining how to use an App (namely BTStack Keyboard) from the Cydia Store (which of course comes with jailbreaking the device) to use Bluetooth Keyboards with your iPhone. The only catch you ask? It costs 5 Dollars and since I neither own an iPhone, nor a Cydia Store Account (or whatever is needed to buy their Apps) my trail to success stopped there.

If there is another approach, be it for jailbroken or non-jailbroken iPhones please let me know. Nothing would please me more than knowing that Apple isn’t having such a tight stranglehold on its customers after all. Smartphones set aside, I’m one of them as you can see from the picture.

Of course it’s not surprising that the Nokia Device works with an Apple Keyboard. The Bluetooth Standard is the same for everybody, also for Apple luckily. And of course it might not make perfect sense to everybody that I’m connecting a Keyboard to a Mobile Phone that has a QWERTZ Keyboard built-in. To be honest I’d know a lot more to do with such a keyboard on an iPhone than on this N97 Mini. Seems like it’s not supposed to happen.
