Apple MBP three screen setup

I just received the USB UGA-2K-A DisplayLink adaptor and it's working great! I'm seriously impressed by the no-hassle-plug-n-play. That's the good thing about having lowered expectations, you're pleasantly surprised when it does work.

I used the latest alpha 2.0 version drivers available from DisplayLink's site.

Sweet!

I've got the old mini-DVI-to-VGA plugged into one monitor, the DisplayLink adaptor into the other one and the MBP screen working too.

ITU and their lost battle to charge YouTube

ITU's Final acts of the World Conference on International Telecommunications, Dubai 2012, is out. 

Besides begging for money and trying to stay relevant, the ITU ratified 'Deep Packet Inspection' (DPI). They also managed to insert this gem: "optionally requires DPI systems to support inspection of encrypted traffic “in case of a local availability of the used encryption key(s).” [1]

What that means is that should your ISP magically come into possession of say your private keys, they are allowed to decrypt your email, communications etc. that you used to encrypt it, forever without telling you.

Their shameless money grab was left for last, on page 23 of the Final Acts titled 'International telecommunication service traffic termination and exchange'. It recognises that dedicated phone and data has moved to IP based networks and many Member States are asking for their authorised operating agencies to invoice service providers. In other words, many Governments are asking, on behalf of their state-run-money-losing telecos, to invoice YouTube for sending traffic to their users. 

The sooner these governments accept the fact that state run telcos are worse than state run airlines, the sooner they can stop begging YouTube for money and implement an open platform for all telecommunication firms to flourish.

iPhone Test Field Mode, Serving PLMN Info and Cell ID.

I'm working on a project and needed to validate the Location Area Code and Cell ID in my tests with actual info from my mobile phone. Using an iPhone and going into Test Field Mode did the trick.

Go into Test Field Mode:

• Dial *3001#12345#*
• MM Info -> Serving PLMN - Gives you MCC, MNC, RAC and LAC
• UMTS Cell Environment -> UMTS RR Info - Gives you Cell ID

There's much more information there and it's very handy since you don't need to muck about in an app.

Android land at Mobile World Congress 2012

A little late but here are some shots from Android land at Mobile World Congress 2012.

An android making little Android statues.

Club Android.

MWC: Huawei pretty booth

Huawei has got a very impressive boot here at MWC and some very neat products, but I didn't have much time as I was just passing by on my way to see Android's booth!

Location:Plaça d'Espanya,Barcelona,Spain

Mobile World Congress

It's here once again, Mobile World Congress or MWC, is upon us and mad scramble for free badges is in full swing. You'd think a pretty large company would have this all sorted out by now, but what's the fun in that, besides as my crazy aunt always says, procrastination is the art of keeping up with yesterday.

So there you have it, I've just got my badge sorted out and I'll be there everyday till it's over. It's being held in beautiful Barcelona, Spain. Engadget have a beautiful picture of the venue worth checking out.

I'll be out and about looking at cool things to come and will try to live blog as fast as I can. So stay tuned folks because there's more to come.
