when things move as fast as satellites move, you never really know where they are. even a 0.01% uncertainty in velocity of a typical satellite going ~2000m/s... after about a minute the resulting position would have a bounding box of 12 meters. Now, after an hour, a day? It's not too difficult to lose track of where you need to point your radars to find your bird.

[Calculation is very general, I pulled that 0.01% velocity uncertainty from my ass]

The CEO of VMWare Paul Martiz thinks that everyone is moving to Python/Ruby, specifically Django and Rails as replacements for the J2EE stack. http://www.enterpriseirregulars.com/27968/vmware-ceo-django-rails-open-frameworks-packaged-apps-as-commodity-and-the-new-kingmakers/

Think of it what you will, but unless you've tried to write a small-medium sized project in Python (as suggested by ESR: http://www.linuxjournal.com/article/3882 ) then you don't know what you're missing, especially if you're moving from Java.

Actually, I thought it deserved a comment because he reversed the usage on both:

Google has plans to scale they're broadband experiment up to 50,000-500,000 homes before their done.

Should be "Google has plans to scale thier..." and "...homes before they're done."

Such improper usage leads me to believe that the original poster just does not understand proper grammar.

You're wrong, please don't be defensive.

Nothing was ever designed in Alabama. Defense contractors in Southern California (mainly Los Angeles) used fabrication facilities to manufacture things in Alabama, but all of the science was done in LA. All of the scientific brainpower for those companies have never resided in Huntsville, it's a shithole.

And JPL? I thought that was a Caltech institution? You know, in eastern Los Angeles? And Los Alamos National Lab in Santa Fe, NM might have something to do with the design of the nuclear bomb.

Because a company or an institution has offices in a rural southern state for cheap menial jobs, does not mean that those laborers contribute science or engineering designs. They don't.

Social Networks

Roughly 3 out of 4 Tweets ignored -> 2

alphadogg writes "Social media analytics company Sysomos studied 1.2 billion Twitter posts made over the past 2 months and found that 71% elicited neither a retweet nor reply.

"When a tweet generates a reply (aka @) or a retweet (aka RT), it suggests the tweet has resonated enough with someone that it sparks a conversation or encourages someone to share it with their followers," the company writes. http://sysomos.com/insidetwitter/engagement/

Of course this doesn't consider that lots of people read or view content — on Twitter and in other forms of media — and don't necessarily feel compelled to respond.

According to the Sysomos study, just 6% of Tweets measured got retweeted and 23% were apparently intriguing enough to warrant a reply."
