Days ago Financial Times published a nice article by Gillian Tett about how the hand-to-mouth living is harming the 'recovery' of the US economy. In general, hand-to-mouth living implies that you fully spend your income to keep your current 'status quo'. It also means that the economy would work in cycles that cannot be detected by medium-term censuses. Read More
Not everyone likes to build things, some people prefer to do things. Because I come from a family of aviators and aviation-related workers. I became a pilot soon as I could. I love to fly and I was sure that being an airline pilot was the only career I would ever want. I was wrong. Read More
I've been using and maintaining large oracle databases for more than 12 years. I'm a fan of oracle databases. Oracle:
- Is incredibly fast when dealing with complex queries;
- It is easier to maintain than competitors when HA is necessary;
- has a rock solid performance and management makes it almost stupid-programmer proof;
- It's cool: all software can be freely downloaded from oracle.com;
- seems to be committed into supporting cloud solutions;
- is really great in support (at price).
But there is something about oracle you should know before choosing it as your database server... Read More
At the flight school people always ask me:
"Can I land a plane? I have X years of flight simulator experience."
Short answer is: history shows you will probably die. Probably not because it is difficult but because you don't know what you don't know. Flight simulators distort important aspects of landing airplanes: your awesome 200 degrees/3D vision, the muscle mechanics of flying and the notion of distance. In fact, flight simulators are harder than the real thing. Yet, many in the flight school I teach landed without the need for intervention in their first flight. I landed an airplane for the first time when I was 11 years old. With a bit of luck you can do this by yourself. So, in case of an emergency, this is what you could do... Read More

I built a small credit card company, we have around 500k users and 2k merchants. We focus primarily on the low-income families, our service is free to users, just merchants have to pay (and our price is 60% lower than visa's) that's how we could outmaneuver pretty much all the big guys in the employee-benefits market. We are a company of just 12 employees now, we live in the cloud, our costs are just a very tiny fraction of the cost our competition faces, they could never compete with us on a level playing field. They were all screwed and they know it, and we received some buyout offers, which we refused... Read More
