Are you in Law Enforcement? Do you have problems correcting erroneous CCTV timestamps? There’s an App for that!

My friend Dario has written one:

Clock Check — By Dario Persechino


Clock Check is an application designed to aid CCTV engineers and Law Enforcement personnel when calculating the time discrepancies on CCTV systems.

The app calculates the difference between a ‘real time’ and a CCTV ‘system time’.

This difference can then be used within the app to calculate when on the CCTV system an incident should be searched for.

The app also provides a facility to save the details of checks for later statements or further calculations.

Two further barriers to UK mobile money – /ht @Penrillian

I’ve done some work for Penrillian in the past, and I am rather liking Charles’ blogging:

The prospect of mobile money is exciting to Network operators, phone manufacturers, payment networks and banks: They’re all looking forward to consumers making payments with intelligent devices, creating better opportunities for customer engagement, and bringing benefits in terms of greater money security. Moreover, the devices are paid for by the consumers. There’s a vision of a ‘cashless society’ where we really don’t need cash at all; where all payments can be through electronic services.

Of course there are a number of barriers to the take-up of such a service.  At the moment everyone’s concentrating on the most obvious ones: lack of technology, smartphones, infrastructure, commercial agreements and lack of ‘anonymity’. 

Yet if the vision of a cashless society is to be realised, the UK has two further barriers […]

Samsung Galaxy S3 ‘sudden death’ security flaw fixed in UK | CNET UK

Samsung is beginning to roll out a security patch to UK Galaxy S3 phones, designed to clear up a bug in the S3’s Exynos chip that could potentially see some phones being wiped or bricked by naughty hackers.

The sudden death bug, as it’s known, was found by an XDA Developers user and gives hackers access to the RAM of phones including the Galaxy S2, S3 and Note. “RAM dump, kernel code injection and others could be possible via app installation from Play Store,” user alephzain explains.

Samsung has pointed out that it only affects a very limited number of devices, but it could affect those running stock Android or custom ROMs after rooting the device.

YAY: “Android X server « my20percent” # X-Windows On Android. Phones are becoming Workstations are becoming Servers.

Voici Android X server « my20percent:

For the past few months I’ve been implementing an X11 server to run natively under Android. In the near future I may have need for a serializable user interface, so to get a better understanding of how they work I decided to implement the de facto standard, X11.

Well, it turns out the X protocol is bigger than I thought, but through sheer bloody-mindedness I got it finished. And it might actually be useful.

I had assumed that all internet-enabled smartphones would be sitting behind NAT-ing routers, both for security reasons and to conserve IPv4 addresses. But no, on the ‘3’ network in Australia at least, phones all have externally-accessible IP addresses, meaning they can run servers. So you could potentially launch a Linux X application out in the cloud and have it display on your phone.

The user interface is fairly simple: touch the screen to move the pointer, and use the directional pad to activate the left/middle/right buttons. Update: the volume up/down buttons now work as mouse left/right buttons. Both virtual and physical keyboards are supported.

The source code is available at under an MIT licence, and the application (called X Server) is available for free through the Android Market.

For me, though, the money quote is:

on the ‘3’ network in Australia at least, phones all have externally-accessible IP addresses, …

…now where have I heard of the desirability of that before?

Discovery of the Day: Phone Touchscreen + Alcohol Wipe = Better Performance

I try to keep my phone (Galaxy S2) as clean as I can but frankly the past few weeks it’s been getting pretty grubby, and no amount of microfibre-polishing the glass seems to stop it feeling slippery.

Then this afternoon I used an iso-propanol screen wipe on it.

Massive change. Greasy feel gone, slight finger-drag is back, still picks up new fingermarks but after polishing it still feels “better” than before.

So – at least with this phone – the screen seems to appreciate a careful deep clean, occasionally.

PHP, the web’s most popular programming language, is coming to mobile # one for @glynwintle HT @jimfinnis

A certain kind of developer loves to hate on PHP. They are really going to hate where PHP’s custodians are taking it next.

PHP was created by Danish programmer Rasmus Lerdorf in 1995. In 1997, Israeli programmers Andi Gutmans and Zeev Suraski rewrote the parser, creating the base for PHP 3. By 1999, they had built the Zend Engine, which is still the interpreter for PHP.

Gutmans and Suraski continued their partnership with Zend Technologies, a commercial entity that creates add-on products and services for PHP developers, particularly developers in the enterprise.

Today, after multiple massive iterations to the codebase, 35 percent of web traffic is handled by PHP, says Gutmans. Wikipedia says 75 percent of websites use PHP. Facebook, Wikipedia, Yahoo, and Photobucket are all built in PHP. WordPress, the most popular blogging platform in the world, runs on PHP and probably accounts for half of that 35 percent. Most of the other major content management systems, such as Drupal and Joomla, are also built in PHP.

3G Google Nexus 7 inbound • Reg Hardware

Actually, I don’t mind this. I am getting on awfully well with Bluetooth tethering and only one phone bill.

Asus is ramping up production of a 3G-enabled Google Nexus 7, it has been claimed.

Citing a “well placed insider”, website Modaco says the cellular-connectable tablet will launch in roughly six weeks’ time.

The real reason that 4G rollout is lagging behind in the UK

On the radio they are discussing this pressing matter: why we are so far behind the rest of the world in 4G rollouts.

Surely they must know that British radio waves can only carry a fraction of the traffic that (say) American airwaves can.

That’s why we can only have up to 5 terrestrial TV channels, and why Radio 2 had to take up a full 4MHz of bandwidth to capture the chestnut tones of Terry Wogan.

It’s quality… or the weather… or something.

Police Tape: an ACLU mobile app # and a reason to prefer Android over iPhone #security #opensystems

Sometimes having a curated application store is a benefit; other times it’s a risk:

Police Tape is an Android app from the American Civil Liberties Union that is designed to allow citizens to covertly record the police. When activated, it hides itself from casual inspection, and it has a mode that causes it to send its recording to an ACLU-operated server, protecting against police seizure and deletion.


The ACLU says that an iPhone version is “coming soon,” though it remains to be seen whether something so potentially controversial passes muster with the App Store.
