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.
