Building out infrastructure for a Traveling Geeks tour

3 December, 2009 by sky Leave a Comment

The Traveling Geeks are at it again. This time the destination is Paris for LeWeb and some other tech meetings.

Organizing a tour for 15 geeks was a nightmarish task for TG Co-Founder Renee Blodgett, who worked for weeks to put this one together – much shorter lead time than for previous tours. And her co-organizers Eliane Fiolet and Phil Jeudy, plus two web developers, did a heroic job.

The online developers were tasked with creating the new web site, but I came in for the last few weeks to preside over one of my (current) specialties – ensuring that we can mash information together in real time. Here’s what it required and what I learned: [Read more…]

Is the Sidekick failure a cloud failure?

12 October, 2009 by sky Leave a Comment

When all data for Sidekicks got lost recently [read this article in the Wall Street Journal] was it a cloud failure or was it a single system failure?^[1] [also New York Times article]

In the sense that data was being stored somewhere and the customer didn’t know where it was, then yes it was a cloud failure. But I contend that it was also a failure caused by the existence of a single-point-of-failure. (As system developers, this is our constant nightmare.) The product/service was set up to use a single data service with (apparently) inadequate backup. That created the possibility of this single-point-of-failure. The real failure was that T-Mobile didn’t provide the option to back up your data in a location under your control, so that you could later on restore it if the central service went down.

Rock on, Net Neutrality

22 September, 2009 by sky Leave a Comment

Please stay aware of this issue – network neutrality means that you, the Internet user, have access to all online content with the same priority. It means that the carriers — both those who provide backbone services and those who deliver content to your doorstep — must not block certain types, or certain origins, of content that is lawfully provided to you.

FCC Chairman Julius Genachowski spoke about this [Wall Street Journal report] at the Brookings Institution earlier this week. He proposes that all carriers, including wireless carriers who handle data traffic, should have to carry traffic without regard to what its content is or who is providing that content. The new provision in his proposal is that wireless carriers would have to carry voice-over-IP traffic as well as other kinds of data, which brings very cheap voice communications to mobile devices – much cheaper than the rates now charged for mobile voice calls.

All those watches! All that bandwidth?

5 September, 2009 by sky Leave a Comment

Being on the road mid-summer, and having to watch my use of bandwidth, I noticed an uptick in the number of spam messages encouraging me to buy cheap watches; or more watches; or fabulous watches; well, you get the drift. Since I already have enough watches, I would like to ignore these messages, but rather than cause me to look at other folks’ wrists, they have caused me to look at the ticking clock of my broadband network usage.

The issue is the use of bandwidth by these messages, and for that matter, the use of bandwidth by everything else. Bandwidth, in spite of our living in the Internet age, was a recurring theme for the entire Traveling Geeks crew. We were on BT Mobile Broadband, which for the most part was reliable. I’d say that we varied between a high of 2.5mbps (mega bits per second) and a low of 4kbps (4k, yes), but if you disregard speed, we seemed to have access almost everywhere in London and Cambridge. Service winked out for a few minutes on the road between London and Cambridge, but regardless of that, there were several geeks online using their laptop computers during the entire bus journey that morning. And I used BTOpenZones, which is a commercial service provided via wi-fi in public places, cafes and hotels. We were given complementary service by BT^[1] and I can see that an average (non-business) user is going to get pretty good service for £10 to £15 a month, but heavy users are going to be bumping against the account limitations and the issue for the geeks is really how much data we are pushing into the cloud. I uploaded a couple of really large videos one day, and overstepped the 4GB cap on my account without knowing it. So BT “topped-up” the account for me, but several of the geeks seem to have hit their limit more than once.

Although I travel a fair amount, I’m seeing that bandwidth is hard to find. Even with wi-fi access, I’m getting top speeds in the 100kbps to 200kbps range. I’m gathering that it is because I’m sharing the connection with others, and yes it does seem that speeds are best in the early morning when few people would be online – and that they can be pretty low when another geek in the same hotel is uploading video – so perhaps shared bandwidth is the real issue.

Augmented reality “HUD” displays on iPhone

26 August, 2009 by sky Leave a Comment

Métro Paris, an iPhone app [see also the FastCompany article] to help us navigate the Paris subway has been beefed up to include heads-up^[1] displays that allow you to see pop-up displays of information about the buildings and businesses around you. You turn on the app and it shows you what your camera is seeing (vélos, motos, voitures moving along the street, and buildings) and rectangular squares pop up that tell you what the buildings and businesses are. In addition, you can get a big red arrow (like in SecondLife when you’ve teleported close to your destination but still have to fly to get there) that points you at a nearby Métro station that you can duck into to take the train to your destination. These augmented reality^[2] apps [see article on LA Times site] have been rumored to be on the way for quite some time. Apparently the heads-up portion was sneaked (snuck) into the app without Apple pretty much noticing that it was there. Thus the speculation about whether it‘ll be taken down. The photos/videos tell the story – take a look. [SEE VIDEO BELOW vids are in French – the demo is at Place de L’Opéra – I know it well.] [Read more…]
