Is that 50-55% estimate conditional on no civilizational collapse or extinction event? Either way, it seems very optimistic. According to current actuarial estimates, a 30 year-old has about a 50% chance of living another 50 years. For life expectancy to dramatically increase, a lot of things have to fall into place over the next half-century. If you think anti-aging tech will be available in 30 years, consider how medicine has advanced in the past 30. Unless there are significant breakthroughs, we're sunk. I'm signed up for cryo and I donate to SENS, but my estimates are much more pessimistic than yours.
If you want to improve your writing, I strongly recommend The Sense of Style, by Steven Pinker. He explains why certain guidelines usually make text clearer, shows how they can fail, then gives the underlying mechanisms for why. It's a much more scientific look at language than the usual, "Trust my advice because I'm good at writing. Do this. Don't do this. Except sometimes, do."
The real answer is: Whatever you can get yourself to do regularly.
If you don't exercise regularly, deciding on a sport is like a picking a programming language before you've learned even one of them. There is no one-size-fits-all sport or exercise. It really depends on your interests, physical abilities, social circle, the weather, what's near you, etc. This discussion might help give people ideas, but so could a list of sports. The most important thing is to get out there and do something.
Also, your quoted example sounds like a just-so story. I thought bowling and football were popular because they're an excuse to drink with friends.
I think Eugine_Nier means to imply (and I would agree) that anybody using SSL2 is incompetent when it comes to security.
If you have a significant amount of money in your account, I recommend asking your bank about multi-factor authentication. I had to pay a small fee for it, but Wells Fargo gave me an RSA token for my accounts. Its use is required when transferring funds to other banks. So even if my password is stolen, my money is safe. Silicon Valley Bank has a similar scheme using SMS authentication.
For #1, "I reacted immediately" and "I reacted when the urgency became evident" are probably the same thing for most people. I heard about the bug 20 minutes after it was announced, from the Cloudflare blog of all places. Not even USN had posted about it. I patched my servers within an hour, and spent the next 5 hours waiting for my CA to respond to my revocation and re-key requests. Apparently they were inundated.
On the bright side, I prepared for security issues like this. I used multi-factor auth for our admin tools and perfect forward secrecy cipher suites for our TLS. Even with our private key, previously recorded traffic cannot be decrypted. And if an attacker got ahold of our passwords, they would still need to steal our YubiKeys to get access to our admin tools.
Hooray for being paranoid about security.
An update for those who are curious: Ag is now the 11th most-starred C repository on GitHub. It's more popular than memcached or Arduino. It will soon surpass XBMC to become #10. People freakin' love it.
The risk of dry eye is because LASIK cuts a flap in the cornea, severing many of the nerves that sense irritation and dryness. Other procedures like epi-LASEK or PRK don't involve cutting into the cornea, so their risk of dry eye is much lower. Unfortunately, those procedures are more painful and take months to heal. They involve scraping the epithelial cells off of your cornea, zapping your eye, and then letting them grow back. On the bright side, there is no flap that can be dislodged by a blow to the eye.
I got wavefront-guided epi-LASEK a few years ago. My vision went from 20/200 to 20/15. It can be pricey ($5k), but it's definitely the best money I've ever spent.
I defy your assertion that both societies are similarly happy. Unless the telepath society is extremely accepting of fringe thoughts, it's going to be worse. Knowing that others will read your thoughts and judge you for them causes you to censor yourself. But at that point, it's already too late. People will know that you thought of something objectionable and suppressed it out of fear of judgement.
Really though, the two options are silly. Ems allow for so many more possibilities. A society in which people could voluntarily expose their thoughts would have quite a few advantages. Ditto for a society with perfect (optional, voluntary) lie detection.
I do not. Your praise is more than enough.
Also, I have pretty much everything I want that can be ordered off Amazon.
My co-founder and I launched Floobits, a tool for remote pair programming. We'd been soft-launched and were slowly growing through word of mouth, but we hadn't tried to get publicity or told the world that we're a Y Combinator startup.
We got coverage on:
...and a couple other places I've forgotten about.
I also wrote an insubstantial post about getting into YC. It doesn't contain any special hints, just a summary of the journey so far.
Demo day is next week, so maybe I should have waited to post in this thread. :)
