Driverless Cars Hitting U.K. Roads This Summer
The U.K. will publish guidelines for self-driving car tests this spring, with the first cars on the road this summer.
The U.K. government today announced plans for the testing of autonomous vehicles on public roads.
Britain has been eyeing driverless cars since July 2013, but until now, the ability to test them has been limited. A six-month review of the technology released today, however, finds that the time has come to start testing self-driving cars in real-world situations.
"Driverless cars are the future," Transport Minister Claire Perry said in a statement. "I want Britain to be at the forefront of this exciting new development, to embrace a technology that could transform our roads and open up a brand new route for global investment."
"A Code of Practice will be quicker to establish, more flexible and less onerous for those wishing to engage in testing than the regulatory approach being followed in other countries, notably in the U.S.," U.K. officials said.
"The U.K. is at the cutting edge of automotive technology—from the all-electric cars built in Sunderland, to the Formula 1 expertise in the Midlands," U.K. Business Secretary Vince Cable said. "It's important for jobs, growth and society that we keep at the forefront of innovation."
Last summer, the U.K. launched a country-wide £19 million competition to find a handful of cities to host driverless car trials. The winners—Greenwich, Bristol, Milton Keynes, and Coventry—"will help to ensure we are world leaders in this field," which Cable expects to be a £900 billion industry by 2025.
Cable and Perry will visit Greenwich to witness the first official trials of the fully autonomous Meridian shuttle (pictured). The ministers will also unveil a prototype of a driverless pod to be tested in public areas in Milton Keynes, as well as a BAE wildcat vehicle set for testing in Bristol.
The first driverless cars supported by Cable's prize fund are expected to hit the road this summer.
"These are still early days but today is an important step," Perry said. "The trials present a fantastic opportunity for this country to take a lead internationally in the development of this new technology."
The U.K. wants to formally update its domestic regulations to include self-driving car technology by the summer of 2017 and update international regulations by the end of 2018.
In the U.S., self-driving car tests are being conducted on a state-by-state basis. California started issuing self-driving car permits to manufacturers last year, though they must adhere to certain restrictions.
Top 4 Fingerprint Scanner Enabled Smartphones Available in India
If privacy and security is on top in your priority features list, you will really want to have a fingerprint scanner in your Smartphone. Top smartphone manufacturers are now getting the wind of what their customers want and they have started offering a fingerprint sensor in some of their smartphones. Motorola was the first company to offer this facility in its flagship smartphone. In 2011, among Android phones, Atrix became the standard-bearer by getting this feature. While passwords can be guessed, your fingerprint is your own. The bottom line is that a fingerprint scanner can give you peace of mind: You know that your work data won't be compromised even if your device is lost or stolen. Here today at GizBot, we have listed all available Fingerprint reader enabled smartphones. Do take a look and choose your pick.

6 amazing things you didn’t know about your computer
It’s a ritual across the globe: somewhere between sticking the kettle on and complaining about last night’s match, you’ll probably hit the button on your ageing company PC and wait while it slowly thinks about turning on. Rather than take it for granted, though, it’s worth taking a couple minutes to realize a few of the things that your poor robot slave does without you ever knowing.
1. Bits, Bytes, and Size
Next time you complain about the pitiful memory capacity of your old 8GB iPod Touch, it’s worth remember what makes up eight whole gigabytes. Computer science grads will know that in every gigabyte, there’s 1024 megabytes; 1024 kilobytes in a megabyte, and 1024 bytes in a kilobyte. Breaking it down to the lowest level, you’ve got 8 bits in a byte.
Why does that matter? Because on a flash drive, each bit of data is made up of eight separate floating gates, each comprising two physical transistors, which can basically record themselves as either a ‘1’ or a ‘0’. (Want to be impressed ever further? Each floating gate actually relies on quantum mechanics to work.) That means that an 8GB iPod Touch – the one you were laughing at a minute ago for being puny – has, according to my back-of-the-napkin maths, 549,755,813,888 individual gates arrayed inside that svelte aluminium body. Mighty clever engineering indeed.
2. Everything you see or hear on the internet is actually on your computer
All your computer-whizz friends probably delight in telling you how having a ‘library’ of videos is so 2008, that no-one torrents any more, it’s all Netflix and iPlayer and ‘The Cloud’, whatever that means. But, you might want to remind them: every time you stream a video or the week’s latest Top 40 off the web, it’s actually, technically playing off your computer.See, every internet media file has to make a local copy of itself on your machine, first. Ever wondered what that white buffering bar means on YouTube or Netflix? It’s the amount of video that’s been copied to the local cache, a.k.a. the amount you can still watch if your internet decides to up and die.
3. The distance data travels
A quick experiment for you: click this link, which should take you to Wikipedia. With one click, you’ve just fetched a bunch of data from servers in Ashburn, Virginia, about 6000km away. Your request has travelled from your computer, through a local Wi-Fi router or a modem, up to a local data centre, from there onwards (under the Atlantic Ocean, if you’re in the UK), all the way to Virginia, and back again – in around 0.1 of a second, depending on how good your internet connection is.
By comparison, your body takes around 0.15 of a second for a signal to pass from your fingers, up your spinal cord to the brain, and back down again.
4. Counting Starts at Zero
At a base level, every computer’s just a really big, complicated calculator. But thanks to the way its intrinsic circuitry works – with lots of little logic gates that are either ‘on’ or ‘off’ – every action that takes place at a base level is happening in binary, where things are either a 1 or a 0, with no shades of grey in between.
This actually translates up to a neat bit of programming trivia – in the computer science world, all counting (with the rather notable exceptions of Fortran and Visual Basic) starts at zero, not one.
It actually makes a lot more sense – ever thought about why the 20th century refers to the 1900s? It’s because when historians decided on the dating system, they weren’t clever enough to call the very first century (0-99AD) the 0th century. If they had, we’d probably have far fewer confused school children the world over.
5. The work that goes into a Ctrl+C, Ctrl+V
One rather under-appreciated fact about solid state drives (SSDs), regarded as the gold standard for fast, reliable storage, is the amount of copying they have to do. When you want to copy some data from one bit to another, it’s not just a matter of shuffling the data from one part of the drive to another.
Because of the complicated way a SSD works, over-writing a block of old data with some shiny new data isn’t as simple as just writing the new stuff in with a bigger, thicker Sharpie. Rather, the storage drive has to do some complicated shuffling around.
In practice, this can mean that writing a tiny 4KB file can require the drive to read 2MB (that’s thousands of times more data that the 4KB file you’re trying to write), store that temporarily, erase a whole tonne of blocks, then re-write all the data. It’s rather labour-intensive, so think before you juggle your files around next time.
6. Code isn’t as clean as you think
The majority of us put faith in bits of technology you don’t quite understand – be it committing your life to a 747, or your dirty pics to Snapchat’s auto-delete. When you do you generally tend to assume that the code’s been scrupulously examined by teams of caffeine-fuelled programmers, with most of the niggling little bugs found and nixed.
The truth seems to be quite the opposite. One Quora user pointed out that buried within the source code for Java, one of the internet’s fundamental bits of code, is this gem:
/**
* This method returns the Nth bit that is set in the bit array. The
* current position is cached in the following 4 variables and will
* help speed up a sequence of next() call in an index iterator. This
* method is a mess, but it is fast and it works, so don’t f*ck with it.
*/
private int _pos = Integer.MAX_VALUE;
It just goes to show that even programmers rush things to get home for the next installment of Game of Thrones sometimes.

Major security alert as 40,000 MongoDB databases left unsecured
More than 40,000 MongoDB databases are floating around on the Internet, present major threat to stakeholders
The NoSQL company MongoDB sufffered a major setback today when a group of students from Saarland University in Germany, found out that nearly 40,000 databases were accessible online due to the lack of security mechanisms in these databases. One of these alone includes around 8 million customer phone numbers and addresses.
The 3 Musketeers
These 3 students – Jens Heyens, Kai Greshake and Eric Petryka – from Saarland University in Germany were behind the discovery that databases running as a service or those being used as a website backend could be accessed by anyone on the internet and gain read and write access to them.
“Without any special tools and without circumventing any security measures, we would have been able to get read-and-write access to thousands of databases, including sensitive customer data [and]live backends of web shops,” the students wrote.
Their view is that these mechanisms were not put in place as the tutorials and guidelines do not mention them specifically.
Organisations that set up MongoDB web servers following these guidelines are likely to have overseen the importance of activating security mechanisms and left the databases open for access on the internet. After doing a simple search the number of database instances vulnerable that they found were 39,890. This number though, could be much more higher as major corporations block such scans and searches.
MongoDB by default executes on TCP port 27017, so anyone would simply need to run a port scan on the internet to find openly accessible databases, according to the students, who said it was ‘incredibly easy’ and could be achieved within four hours. They also mentioned about a search engine Shodan, which has a database containing IP addresses with a list of services running and an easy-to-use filter mask.
Lack of acknowledgment
“The fault is not complicated, but its effect is catastrophic,” said Michael Backes, professor of information security and cryptography at Saarland University and director of CISPA, who was contacted by the students at the end of last month. The students informed the French Data Protection Authority (CNIL), the Federal Office for Information Security and MongoDB so that the affected database owners could be notified. But the anger is not because of the flaw, it is being fuelled by the lack of acknowledgement of the existence of the flaw.
Dent in the growth
This revelation will cause a dent to the growth story of NoSQL systems, which have in recent years challenged the use of relational databases with the prowess of handling greater data sets with better efficiency. As the leading open-source document database, MongoDB is at the center of this trend with several major websites and services integrating it for their backend. This security alert is likely to be a setback for the company, which last month was valued at $1.6 billion after a new round of funding from investors.
