I think as long as the objects in LEO are well documented and publicly tracked, it would not be much of a trouble to filter them out

When I travel to Kiev, Ukraine, that's what I use. The cab industry is pretty much de facto deregulated there. And you know what? It's great! It's dirt cheap - vast majority of fares are well below $10. There are apps, that allow me to order taxi from many different companies at the best available rate, and yes - the rates are specified instantly. No need to guess how expensive your trip is going to be. I traveled many dozens of times - not a single problem. The need of regulation in this industry is overrated.

The energy efficienty of fuel cell powered cars is abysmally low in comparison to electric. Infrastructure is almost non-existent and requires major investments. Hydrogen is very leaky and requires very high pressures for storage. There is a decent electric car already mass produced: Tesla Model S. I know that the batteries are pretty expensive, and energy density needs improvement, but for the sake of keeping our planet in better shape, I hope electric beats hydrogen.

I spend hours per day browsing internet. It seems like I am addicted to it. However when I travel overseas or do some hiking, I find absolutely zero withdrawal symptoms, even if I am offline for weeks at a time. The real addiction I have is not to the internet, but to brain stimulus. I hate boredom, and when I'm static, boredom sets in and makes me want to get online to get mentally stimulated. When I do some work around the house, talk to someone or travel, my brain is stimulated enough to not have a need for internet.

It might work if your web sites are not particularly popular. Above a certain threshold of popularity, spammers might actually personally visit your site to fine-tune their spam scripts.

They serve absolutely opposite purposes. Java is all about cross-platform support. .NET, on the other hand, was created by Microsoft for Microsoft lock-in. Don't even start about Mono. The shop that I work for develops software for 5 platforms: Windows, RHEL, HP-UX, AIX, and Solaris. For our core performance demanding jobs we code in C++. Everything else - mostly Java + few scripting languages. .NET is simply not in our lexicon for a good reason. It would be utterly useless for us.

According to the latest news. Also failed to find the Sun, and there are three days of battery power left before it's dead. BTW grunt means soil in Russian

Just go with the crowd.

You mean if somebody has physical access to your hardware on day-to-day basis? We are not talking about that. As several posters mentioned before - stolen laptop is the main concern here. If the disk is encrypted with a good key, this cold-DRAM-reading is the only viable and relatively easy method of stealing sensitive data from it. The best solutions I've read so far today about: 1. Getting rid of the somehow marked sensitive information from memory, while switching to sleep mode or to locked mode. This method will need lots of code change and full cooperation of OS and application developers. 2. Using capacitor based backup power on motherboard to wipe memory clean at the moment of power loss. This method is easier to implement but less reliable, since you can pop RAM from the motherboard while it is still on, or just destroy that capacitor before power off.
