Recently, I was trying to execute some very time consuming commands on
a Linux server. It turns out if your SSH connection gets
disconnected it eventually times out and tears down your session,
includuing whatever you were doing if it's still running. After
the third disconnect I got mad enough to do something about it.
That's when screen saved the day. After a quick yum install screen I was up and running. Just run screen and compute away. If you get disconnected, reconnect with a screen -d -r.
Everyone's favorite software slinging straight talking blogger, Joel, has a few things to say
about why he thinks superstar programmers are the key to success in the
software business. The basic economics of the argument go like
this... You don't pay for programmers when you sell software, you
pay for them when you create the software. That makes the extra
up front investment more that payoff as you prance around the Internet,
gleefully selling your wares at near zero marginal cost. One of
the success stories he sites is the iPod, only half software, which
begs the question - do his conclusions about individual productivity
and investment in product creation apply more generally? In
particular, I wonder if this model is as effective in the open source
world where you are mostly competing on service, attaching a higher
marginal cost to each sale. If anything, I think it might be more
important. Even if your margins are lower, the creation of the service is still an up front cost and the better it is the lower support costs will be, helping to increase margins.
In other news, MSN's Virtual Earth is Microsoft's latest move in expressing their insane jelousy over Google's coolness. Not surprisingly, it doesn't work very well in Firefox.
