My view on Android

Android is an operationg system developed by Google, and based on linux kernel. It sees phenonmenal growth since 2009, firstly from mobile phones, then to tablets. The growth pattern is also very similar to linux. Linux, is now 20 years old, and is still growing / evolving rapidly. It's very grass-root style movement, based on GPL open source concepts. There's lots of info on the internet, free apps on Google Market. Yet many says that the tablet market is dominated by iPad from Apple, but it's still similar scenario as "Linux vs Microsoft". Linux did not try to compete with Microsoft, and shows no interest on it. Similar belief is in Android. They promote a FOSS ( Free open-sourced softwares ) ecosystem, that let everyone to participate / modify your device. It's same concept that "If you cannot open it, you do not own it" Android may not become the winner in tablet market / mobile phone market, but it won't die. I went to 桑達

Plastic Logic

Cambridge University’s Cavendish Labs and I’m joined by Professor Henning Sirringhaus, who is a founder and chief scientists for a company called Plastic Logic Plastic Logic is a little start-up company in Cambridge that make plastic electronics. So if you imagine your plastic bag that you use to do your shopping that’s a very uninteresting thing. It doesn’t do much. But you can make electronic devices such as transistors, light emitting diodes, solar cells using these plastic materials in the same way that you would use silicon for conventional electronics. Plastic Logic is a company that’s exploiting this materials research for displays. The core of the technology is to make plastic transistors using a plastic semiconductor. So what you need for a flexible display are lots of transistors on a flexible substrate. Plastic Logic uses PET, which is the material from which coke bottle are made as a substrate. It then deposits an array of transistors onto that substrate. It can be

working with MS access mdb files in Linux

It seems there is no easy direct way to work on a M$ access mdb file But you can extract the file contents and convert to csv format, and then use Openoffice to view it 1. Install MDBTools 2. use a python script to automatically convert to a CSV format file here is a link with a small python script to do conversions

So did Einstein get it wrong? Scientists clock particles travelling faster than the speed of light

CERN claims neutrinos went faster than the cosmic speed barrier of 186,282 miles per second (299,792 kilometers per second) A neutrino beam fired from a particle accelerator near Geneva to a lab 454 miles away in Italy traveled 60 nanoseconds faster than the speed of light Read more: http://www.dailymail.co.uk/sciencetech/article-2040735/So-did-Einstein-wrong-Scientists-clock-particles-travelling-faster-speed-light.html#ixzz1Yjq4R7ii “The feeling that most people have is this can’t be right, this can’t be real,” said James Gillies, a spokesman for the European Organization for Nuclear Research, or CERN, outside the Swiss city of Geneva. Mr. Gillies told The Associated Press that the readings have so astounded researchers that they are asking others to independently verify the measurements before claiming an actual discovery. “They are inviting the broader physics community to look at what they’ve done and really scrutinize it in great detail, and ideally for someone elsewher

Things to do before and after Ubuntu Installation

1. harddisk is not recognised by Ubuntu Installer. But you can mount the drive or the partition, and no problem to perform reads or writes Follow this link to remove the tags Ubuntu Installer can't find my SATA drive 2. Logitech Cordless Optical Keyboard I just use "generic Logitech keyboard" and is just fine. The numeric keypads are working correctly. Don't select "Logitech cordless optical keyboard". My model is Y-RK49 3. install numlockx, and modify the X startup scripts, so that numlock is always ON when X windows is started Enable Numlock Upom Login 4. fix the clock As I am using same PC with multiple Operationg Systems installed, the real time clock is used differently. Windows is thinking the realtime clock is local time, while in Ubuntu thinks it's UTC so I change the Ubuntu /etc/default/rcS scripts to UTC=No UbuntuTime 5 Make grub menu visible and with boot messages visible grub2 it is located it /etc/default/grub ma

Sony SLT-A77 OLED viewfinder

Spec : AMOLED 1024 x 768 XGA 100% frame coverage ( should be ) frame rate: 12 fps max review shows that Cons: Sony's new OLED technology does a dramatically better job with highlights than most any EVF approach we've seen in the past, but we found that the tonal problem has now moved to the shadows: In scenes with a wide tonal range, it can be tough to see any detail in shadow areas without momentarily re-framing to get the viewfinder to gain-up a little. Even with the brightness adjustment set to maximum, when I brought the viewfinder to my eye while shooting under bright sunlight, the EVF display was significantly less bright than the surroundings. While great progress has been made, even the A77's OLED display doesn't come close to providing the dynamic range of a purely optical system. Likewise, update lag during continuous shooting is still at least somewhat an issue. Pros: One very useful improvement over optical viewfinders comes at the opposite
