I've lost over 45 pounds and kept it off for over three years so far. And best of all, I didn't do it by starving myself.

I've considered myself overweight for most of my adult and childhood life. Oddly enough, I had always been fairly athletic, and exercised regularly throughout my life. I had strong willpower. But I just couldn't seem to keep weight off.

I lost my weight by signing up for weight watchers online. Weight watchers online is a program that allows you to conveniently keep track of the food you eat. All of it. I don't think weight watchers is magic; instead, I think the process of making eating a deliberate and measured action is what helped me. I like numbers. I can do numbers.

What I found by recording everything I ate is that a small number of foods accounted for a large amount of calories. Beef, fries, bread, snacks. I've largely eliminated these foods from my diet. It's not that I can't eat them, I just don't feel that the value is high enough for the calories to eat them a lot. I was able to decrease the number of calories I ate without starving myself by eating smart. The other benefit of recording food is that there are some replacement foods that are significantly healthier. For me, I started snacking more on pretzels, which I found a lot more filling, but contained less calories than many of the other snacks I ate.

After about a year, I stopped using weight watchers. I had internalized most of the good behaviors, and no longer needed to record everything I ate. I continued to lose weight, slowly but steadily. Eventually I stopped at a healthy weight, and I feel great. Over time, even though I was never starving myself, I started eating higher calorie foods and exercising more regularly to offset it. On that note, for burning calories, exercising longer and with lower intensity is better than short, intense workouts. I like to use the elliptical; I can exercise for 90 minutes without killing myself, and burn over 1000 calories. I've found that playing video games at the same time really distracts me from the act of exercising, and even makes it enjoyable.

If you're skeptical, and think you know enough about dieting to not record everything, think again. There are simply too many surprises. Go to your favorite restuarant's website and look at the nutrition information. I used to go to Chili's quite often. I haven't been there for a long time. I don't know how they cook their food, but it's insanely high in calories. Even seemingly safe foods like salad can be high in calories depending on the dressing. The opposite is true as well. Some fast food, like KFC, can be very low in calories (although probably bad for other reasons). Over time, you'll learn what fills you up and doesn't have a ton of calories. If you just start "eating less" without any data, you'll still be eating the same inefficient foods, and you'll probably gain your weight back after you can't take it anymore.

Take a look at this list of practice or permanent CTFs. The root of the site also has a great archive of past CTFs, and other useful stuff.

As others have pointed out, deploying EC2 instances automatically is fairly easy using the well-documented EC2 APIs.

The difficult part about distributed computing is synchronizing the work between available instances. For this, you might want to look at RabbitMQ or other queueing servers. One way to do this would be to have one thread (on your computer) generating problem instances, while you spawn spot instances on EC2 as desired, which consume the work and report the results. I suspect you could accomplish something similar using Hadoop/MapReduce.

Have you ever put a slingshot in a blender or, conversely, created a blender that could be fired by slingshot?

The news of the earlier hack got me thinking about the unique risk/reward of ubiquitous communication and the challenge of computer security to keep pace. Certainly some say the pace of technological innovation is no longer in step with yesterday's, but that almost begs the question. It's truly ironic that modern computing becomes physically smaller as its footprint on our lives looms ever larger with each new year, yet no one disputes that, lately, electronic progress rests solely within the social stratum these days.

We should ask ourselves, however, the rather basic question of whether this seismic shift in the nature of the changes in technology brings with it an impedimentary effect on our lives, or indeed to wonder to the degree technology has ever been pedimentary when it comes right down to it. Yes, it's certainly got its foot in the door, but as with feet and doors it's not always possible to know at the moment of impact whether said foot represents opportunity, doom, or a casualty of a society overeager to shut the door to change.

Certainly the last thing anyone wants is a race to the bottom. Ah, but that's not entirely accurate when one considers the vested interest shoemakers have in most modern day footraces. It suggests that, moving forward, the most important thing to do when evaluating new technology in 2013 may very well be to first identify the shoemakers for that technology. Ask yourself: if I'm already wearing five pairs of socks, do I even need shoes at this point? Odds are, you don't.

Or, apparently, Raspberry Pi. I really have to get around to buying a couple of those.

I don't think it's something that's prepackaged and easy to install, unfortunately. The principle behind it is here, as implemented on OpenBSD.

For hardware, I guess just a small PC with a wireless network adapter and a wired network adapter. Major thing is to make sure everything is compatible with OpenBSD (or Linux as another option, if it looks like the above process can be tweaked to it). Wireless adapters are a pain for compatibility.

It seems to me as I write this that it'd be really neat if the EFF sold ITX-profile routers preconfigured to create open hotspots that route over TOR.

Typically, you only get one of these around a newly formed star, a T Tauri star, or Herbig Ae/Be star. This discovery really broadens the scope for the types of stars that could yield solar systems like our own, and maybe in turn, the likelihood for finding some sort of extraterrestrial life.

Keep in mind that (with a decent router) you can open your Wi-Fi but route all guest connections through TOR transparently. That might be a fair compromise, along with rate-limiting, capping per-session usage, and setting a hard limit for the month if necessary to prevent yourself from going over your own cap on service.

Open Wi-Fi everywhere actually makes me more nervous for the clients than for the servers. People already don't understand security with Wi-Fi, and need to know that any server they're using can observe their traffic if it isn't encrypted. I guess that's already a concern without open Wi-Fi everywhere, though.

Because there are two worlds colliding here in the mind of the average person.

• The school of thought that the victim is always at least partly responsible for being conned. There's a sense of superiority a lot of people get when they hear about scams where, because they themselves would never fall prey to a scammer, anyone who does is deficient or incautious.

• Anyone charged with a crime involving a computer for more then Solitaire, porn, and recipe hunting must be guilty.

It's been over eight years since the last TrollBack? I don't know if I ever said thanks for those, by the way, so thanks for those; really enjoyed them.

If science required knowledge of the outcomes before it was performed, ask yourselves: how many of the technologies around us would we enjoy today?

Taking the space program as an example, putting a man on the moon was symbolic, but the payback for the research and development went far beyond that. Even if we didn't reach the moon, we got memory foam, orange drink, and satellites out of the deal.

But too many people are unwilling to pay for R&D if they don't have a 100% guaranteed outcome. Well, science doesn't work like that. The best we can do is speculate about the gains from better and better software-based brain models. Simulated protein folding probably seemed a bit goofy to somebody when it was first proposed. We don't know if we don't try.

Fwoooooooooooosh. Fwoooooooooooooooooooooooooosh. KWEEEOW. Fwooooooooooooooosh.

Nah, just edit once and have the other 4999 machines fetch through Gnutella with a batch file. It's not like this isn't a solved problem.

That sounds pretty good. I figured there had to be something more to it if 1500+ people were showing up. 18 years in and my imagination with regard to Linux still only goes so far as to web browse, write code, and beg WINE to run games properly. Though I certainly wouldn't turn away automated beer if it came in the next Ubuntu.
