Flash ahaa...The save-ier of the universe

Flash memory has been dominated by two things of recent times:

Capacity goes up
Price goes down

We now have a 4Gb SD card, that's the same size as a DVD and how well were they lauded when they arrived?

There are prototypes that use magnetic charge (like a traditional hard drive) opposed to the [volatile] electric charge.

But what does this really mean?

It means that we are very close to having a non moving part PC. The average size of a hard drive in a laptop today is somewhere between 20 and 40 Gb (although this is trending up) so imagine being able to have 10 such SD cards creating a logical drive. This would take up much less space than a normal hard drive and would give the ability to swap out parts of the storage.

Think of it as SD raid.

Crisis Connections

What the flood situation in Thailand has shown once again is the power of social networks to fill the void of communication. In recent times the role of Facebook, Twitter, and Blackberry messenger has been shown in good and bad light. The same methods that released the Arab Spring have also been used to coordinate the London Riots . Love them or loathe social networks are here to stay and what the floods show is how they keep people connected. Some will say there should be no communication void if central government is on top of its game, but with a situation that can change so rapidly, and over such a large area the traditional press certainly struggle to keep the public up to date. Twitter and Facebook have been saviours for those of us outside Thailand at this time. With roving reporters and connected people like Patee Sarasin and Jetrin out doing and tweeting many more people are kept up to date. Equally useful is the ability to time shift news updates...

AaI and Net Neutrality

On a previous post on Access as Infrastructure there was a discussion on the government led initiatives for ultra fast broadband. The proposition is that the build out of new access networks is such an expensive activity that the governments of Australia and New Zealand will make the investment, using a combination of public and private money. So with ubiquitous access a near reality and with that access provided in the same way as electricity, water, gas, and roads getting to your house what does this mean for the net neutrality debate? If the telco no longer owns the asset and are merely a party in the trade then surely this solves the net neutrality problem? The incumbent may get preferential treatment because of scale and buying power but this wouldn't be extended to priority routing. Moving the competition from the physical platform to the offering, as long as the telcos, CSPs, and RSPs are not government owned, then we can have comfort that the pipe is there and ev...

Muni, Muni, Muni

2006 is going to see an explosion in the activity of Municipal, Muni, Networks. This article from the BBC states that IP access is becoming a basic amenity, in the same way as water and electricity. Philly is the next to be online; with a 135 square mile network being built out by Earthlink and turned on next year. Not far behind is San Francisco with, you've guessed it, Google as one of the prime bidders. They believe they can take their successful advertising revenue stream to provide free IP access to the proletariat. On a brief aside the partnership of Google and NASA, can we expect to see Google in Space? With the benefits of WiFi access to schools, hospitals and police forces around the US it won't take long for a few well publicized examples of how access helped them for the ball to start rolling. I would agree with Paul that the secret to success is a partnership with the existing carriers. Otherwise the likes of SprintNextel could easily freeze the new comers out. Th...
