TUI – no, not the traveling company.
” Text-based user interface (TUI), also called textual user interface or terminal user interface,[clarification needed] is a retronym that was coined sometime after the invention of graphical user interfaces, to distinguish them from text-based user interfaces. The concept of TUI refers primarily to the way of output and does not coincide with command-line interfaces which is a certain user input mode. An advanced TUI may, like GUIs, use the entire screen area and does not necessarily provide line-by-line output, although TUIs only use text, symbols and colors available on a given text environment.”

It’s always fun to see two people from different departmends and backround talking about the same acronym (in this case “TUI”), but from a different context and point of view.
So, they mean completely unequal things and been surprised that the other didn’t understand.

Trotz des steigenden Onlinehandels kaufen viele immer noch nicht online aus Angst und Unsicherheit wegen der Bezahlung. Eine Prepaid Karte ist wie beim Telefonieren schon lange bekannt die Lösung genau dieses Problems. Als Visa, Master, Gold oder sogar Partnercard kann man bei der LBB – Landesbank Berlin ohne Schufa Abfrage sogar in der Version für Jugendliche eben eine solche Prepaid Karte bestellen.

” DroneShield: A simple device that alerts you to nearby drones
DroneShield is a low-cost, easy-to-use device that detects the presence of nearby drones (including RC helicopters, quadrotors, etc) and issues alerts via email, sms, and a flashing light. The goal is to help preserve privacy from low-cost remote-control air vehicles with video cameras.
How Does It Work?
DroneShield includes a microphone that listens for sounds of drones. Each DroneShield contains a database of common drone acoustic signatures so false alarms are reduced (IE ignores lawn mowers and leaf blowers) and in many cases the type of drone is also included in the alert.
Technical Specifications
Our initial target platform is the Raspberry Pi. Other components include a microphone, power supply plugs (or micro-USB battery pack). Wifi connectivity is required for email and SMS alerts. Signature database updates can be downloaded and uploaded on the RPi’s SD card.
What’s the Plan?
The goal of this initial campaign is to create a low-cost device that will help protect privacy against RC helicopters and quadrotors with video cameras; we already have a working prototype running on a laptop. The Indiegogo campaign will port that code to a small low-cost hardware platform that you can plug in and forget about. If you like you can periodically update the signatures of the drones we scan for, or even contribute your own signatures to the database.
Our goal is to port our existing code and database to the Raspberry Pi platform and bundle that with peripherals into a stand-alone product that can be operational right out of the box with absolutely no technical knowledge needed. The funds will be used to buy hardware in bulk (reducing prices) and the developers will donate their time to assemble the hardware and port the code.
We hope that there will be enough interest to justify further development to reduce costs in future generations; we believe ultimately we could get the cost down to the $20-range at scale. Future plans could include moving to an open-source ‘sourceforge’ type development environment and teaming with additional hardware makers. We could also envision a smart-phone based platform for portable applications.”

” One definition given in a recent review on graphene is:
Graphene is a flat monolayer of carbon atoms tightly packed into a two-dimensional (2D) honeycomb lattice, and is a basic building block for graphitic materials of all other dimensionalities. It can be wrapped up into 0D fullerenes, rolled into 1D nanotubes or stacked into 3D graphite.
A previous definition is:
A single carbon layer of the graphitic structure can be considered as the final member of the series naphthalene, anthracene, coronene, etc. and the term graphene should therefore be used to designate the individual carbon layers in graphite intercalation compounds. Use of the term “graphene layer” is also considered for the general terminology of carbons.”

After downloading the application from the App Store and activating Bluetooth, in the application the SensorTag can be connected to the iOS device.To enable the connection, the push button of the SensorTag must be pushed once. The LED on the device will start blinking and the SensorTag can be connected now by the application.
Pictures coming soon …
Texas instruments TI offers with the CC2541 Sensor Tag a nice development tool with quite a lot of functions. The SensorTag includes these sensors:
The complete SensorTag is optimized to low power consumption by TI. When not used the sensors been in sleep mode.
The communication between the SensorTag and the iOS device needs Bluetooth 4.0 and the TI application.

Actually an IEEE / Moverio Video Contest is in progress.
This article and link is just for information and research proposes only, because the possibility of breaking the HDMI security HDCP was shown before.
But that this can be done “so easily” was surprisingly for me.
“I should point out here that I’m not claiming to have anything to do with breaking it. I’m not even going to tell you about some new and interesting way of breaking it that I’ve discovered (although I will show you how easy it is to exploit the vulnerabilities).
So how do we go about figuring out what’s really going on under the hood?
Well, the first thing I did was to build myself an HDMI breakout cable. This turned out not to be as daunting a task as I at first thought. In fact it’s pretty simple:
Get a nice short HDMI cable and cut one end off, or, better still, get a longer one and cut it in half, make two, and give one to your local hackspace!
I had one that had been stepped on, so I just cut the broken end off (my other half thinks I’m more than a little mental for “hoarding” this kind of crap: “Why the hell would you want to keep that broken cable???”, but being able to do stuff like this on the spur of the moment on a rainy Sunday afternoon (did I mention I live in England?) is the lifeblood of the hacker!)
The magic search term for this is “HDMI Screw Terminal”. Once you know that you’ll find loads of them, and you’ll wonder why it took you so long to figure that out in the first place. 
Now you can plug the remaining end of your HDMI cable into the socket, and then buzz through each wire on the cut end to each of the screw terminals. As you find each one, screw it in. This will only take a couple of minutes, and once you’ve finished, the cable will be entirely looped back on itself, with each pin connected one for one, like this:

From time to time, exactly every 2 years customers have to choose between quit or extending the mobile contract. The business terms of t-mobile been fine and when extending the next choose will be between invoice credit or a new phone. Mostly my decision had been the new phone, but which one ?
The technical data was discussed alot and I’ll not repeat it here. I hadn’t experience with the Microsoft Windows 8 OS until now and no time to test. Still Android and iOS on the list. The new Nexus and the Sony Xperia Z wasn’t available at the time of ordering and the other competitors are to heavy in their dimensions for a mobile phone. Decision between Android, iOS and Windows 8 was a neck-and-neck race and the key point had been the invested money in Apps. Binding the hardware and the software in the way Apple does makes it some kind of difficult to change the operation system.
iPhone 5 slims in weight and is still good-looking, overall a good decision.
The Agilent U1731A is a 20,000-Count Dual-Display Handheld LCR Meter for measurement of inductance, capacitance and resistance.
With the SMD probe the U1731A is a nice piece of equipment.
Looking for information about the A-Net, the first mobile infrastructure in Germany, I found this website with comprehensive information.
The site informs about the technology between 1950 and 1994, because after 1994 the market spread extremely fast into a confusing situation with alot of different technics and mobile phones.

” An introduction to wireless charging: changing the way we think about power
Smartphones are changing the way we live our lives, both online and off. With each new model, we are used to getting more processor speed, new features and programs, and entire new ways of using them. Despite increased capabilities, battery life simply hasn’t kept up. For most users, phones are sending out sad bleeps by lunchtime, signaling a low battery.
Wireless charging is set to change this. We want to eradicate the problem of the dead battery.”

“Ever wanted a development kit that flies? Well now you can! The Crazyflie is an open source nano quadcopter kit designed for flexible development and hacking. It’s among the smallest in the world, weighing only 19 grams and measuring 9 cm motor to motor. ”
“British troops are using a nano drone just 10cm long and weighing 16 grams on the front line in Afghanistan to provide vital information on the ground.”
Well it look like the 20 € remote toy helicopters, but the surface of the rotor blade seems to be made out of carbon.
“Powered by battery, the Black Hornet is reported to have a range of about half a mile (800m), a top speed of 22mph (35kph) and can fly for up to 30 minutes.”
It uses GPS for waypoint navigation or can be directly navigated by a pilot. I ask myself how sensitive this drone will be to wind and other environmental influences.
