number10_3.jpgQuite surprised to discover that British Prime Minister Office, the famous 10 Downing Street, is, since very few days, using social networks to communicate on the Web. 

Prime Minister Gordon Brown (at least his PR team) is active on Twitter and photos of the French President's visit to Downing Street have been published, by PM communication team, on Flickr.

Is PM Brown a geek also ? 

Who will be next ? This one perhaps ? :wink:

Q: Will it give enough "respectability" to introduce micro-blogging into corporate environment ? or is it still too early ? I will come on that subject again, after reading Simon's post

emirates_a340.jpgEmirates Airlines announced yesterday that passengers will no longer have to switch off their mobile phones and will be allowed to make calls and text people during their journey on-board.

The first flight with authorized mobile phone calls was made on 20th of March between Dubai and Casablanca on-board of an Emirates Airbus A340-300 fitted with AeroMobile system, which ensures mobile telephones operate at minimum power during flights and make sure mobile phone signal does not interfere with aircraft navigation equipments.

A second aircraft equipped with the same AeroMobile system will be in service shortly.

Rates were not published, but in 2007, cost per minute was estimated between 2.50 and 3.50 USD.

tgvest.jpgTGV tests Wi-Fi + satellite link in three TGV trains on its Eastern network. If the experiment proves successful the new service should be generalized, from 2009, to all 52 oars network East.

With combines effort of satellite link and wireless network, in locations, such tunnels and train stations, where the satellite link cannot be established, the wi-fi network takes over to maintain the access to the Web without interruption.

French railways company SNCF previously conducted unsuccessful test using GPRS data network before launching a 2 years research and preparation program to implement this dual solution. Among technical difficulties to overcome are these related to 320 km/h TGV trains speed which causes instability and vibrations. 

The project is done in a partnership with Orange(France Telecom mobile operator), Capgemini, Alstom Transport and Eutelsat.

SNCF will put on board of its TGV a dedicated Web portal providing information about destinations, weather forecast, News, traffic information as well as a real time tracking service. From a technical point of view, TGV trains are fitted with a server where all portal content is loaded prior the journey in order to minimize bandwidth consumption due to its high cost. The tested system has been designed to provide simultaneous web connection for 14 per cent (50 users) of the total capacity of each TGV train (350).

The business plan is not defined yet, but the widespread of the system on TGV Eastern Europe network would represent an investment of 120 millions USD over 4 years. First price estimation given by SNCF Passenger service would be a flat 4-5 USD to access the Web portal during the whole journey and a 4-5 USD per hour to access the Internet.

A very interesting project and definitively a real challenge to maintain permanent web connectivity during a train journey at more than 300 km/h where the 16'000 volt power line running over the train may also create some electro-magnetic interferences and without mentioning all micro interruptions of the satellite link each time the train pass under a bridge or when dense foliage is found within the satellite's line of sight.

Any reader who already had the chance to test the reliability of the service ?

samsungg800.jpgSince, mid-2006 mobile phones with a built-in 3 MP camera and optical zoon are available on the market and already represent an alternative to low end digital camera. More than 70 models are available today with a 3 to 5 MP resolution. One of the first phone with a "real camera" was the famous one Nokia N93 and its Carl Zeiss Optics.

Samsung is now putting even more pressure on camera makers with the soon release (first on European market) of its G800. A 5 MP digital camera with 3x optical zoom into mobile phone… or is it the opposite? 

The specifications are rather attractive:

  • Quad bands (900 / 1800 / 1900 / 2100  )
  • Data network HSDPA 7.2 Mbps
  • 2.4 inches TFT display with 256K colors
  • Size 101x52x19mm for 129 gr (25% lighter than the Nokia N93)
  • Standby 220 hours, talk time 3.5 hours.
  • Memory 160 MB + MicroSD slot
  • Document views (Office, PPT, PDF,)
  • Email (POP3, IMAP), SMS, MMS,
  • Connectivity: Bluetooth, USB 2.0, PCSync, OutlookSync, etc..
  • FM Receiver, Java embedded, MP3, etc..

and indeed the built-in camera:

  • 5 Mio Pixel
  • 2592х1944 pixels
  • autofocus
  • video recording mode: MPEG4, 3GPP, H.263, H.264
  • xenon flash
  • 3x optical zoom /4x digital
  • 4 shot modes
  • 4 quality settings
  • brightness adjustment

 All other specs are here

The big plus is definitively the 3x optical zoom which makes the difference with other 5 MP phones.  The resolution race continues as Samsung (them again) Electro-Mechanics announced on November 15th that 8 MP camera phones may be available by next summer following the successful development of a 10.5 x 11.5 x 9.4mm 8 megapixel CMOS censor.

Will camera makers develop new "point and shoot" camera with built-in phones  and multimedia facilities such MP3 player and FM receiver ?

I'm impatient to have one "box" less to carry when traveling…

What will you drop first ? your camera or your phone ? ;-)

upa.gif8th of November: World Usability Day "Make life easy" 

Swiss UPA, the Swiss chapter of the Usability Professional Association proposes to ease access to free public wireless networks using a specific sign ((o)) that would help users to detect easy to use wireless networks. 

Today, before getting online using a wireless device, users have first to find an user-friendly wireless access point and then try to connect to it.

The user has to detect which wireless networks are available from his location and check if they are public and free of charge. Often wireless network names do not inform the visitor if the access to the network is free or not. The wireless access point might not be protected but once connected users are redirected to a page where they will be invited to purchase access rights.

Swiss UPS also highlight the fact that once connected to a free and public wireless network, it is not uncommon to reach an authentication page before getting access to the Internet. This procedure has 2 main disadvantage:

  • Some authentication pages cannot be completed when using a Smartphone or a PDA.
  • Some services such email, Instant Messaging, VoIP, etc… do not require the use of a browser and users cannot pass easily through this authentication method.

To make users' life easier, Swiss UPS proposes to include at the beginning of the SSID (Service Set Identifier which broadcasts the name of the wireless network) of public and free wireless networks the  following distinctive sign:  ((0))

Usage of the sign ((o)) is free and open to all individuals, collectivities and organizations which operate a WiFi network respecting  Swiss UPA usability charter.

twineit.jpgRadar Networks, is releasing a free Web-based tool, called Twine, that it hopes will change the way people organize their information.

Twine website is a place where you can share any kind of information and knowledge such emails, bookmarks, documents, RSS feeds, contacts, photos, videos, product info, data records, and collaborate around common interests, activities and goals with friends, colleagues etc.

Once Twine has some information, it starts to analyze it and automatically sort it into categories that include the people involved, concepts discussed, and places, organizations, and companies.

Twine uses the Semantic Web, natural language processing, and machine learning to make your information and relationships smarter.

It still look unclear how Twine could make a real difference about organizing and sharing information but apparently a public beta version of the site may emerge soon.

Another question, Twine will be able to compete with what Techcrunch calls "the Google lethal social weapon", the project Maka-Maka.

Twine register form is available here.
