Let's say today is your birthday. You've just put those boisterous, vicenarian times behind you, reaching the first big step to your upcoming midlife crisis—30 years old. Maybe this is your midlife crisis. After all, if you're not where you want to be in life when you join the tricenarian ranks, the future starts looking bleak.
Today, we are going to combine what we learned from the Introduction to Cryptography article with our Java programming skills. If you are new to Java, check out Matthew's Learn Java: Part One for a quick beginner's lesson, or check out some of the Java tutorials directly on Oracle.

In Linux, all password hashes are normally stored using the MD5 hashing algorithm in the /etc/shadow file, but MD5 is algorithmically weak due to collision vulnerabilities. The new recommended standard are the higher level SHA-2 hashing algorithms, SHA256 or SHA512. As a friend pointed out to me, Ubuntu is currently the only distro implementing SHA-2 as the default. With SHA-2, your passwords take an unreasonably larger amount of time to calculate. This will greatly decrease how many password...

+Eric Cattell, the Social Graph Technical Lead of Google+, announced a lot of improvements and added features this morning, most of them having to do with circle management and blocking people.
Have you ever heard symmetrical is sexier? Yep, according to scientists, symmetry is inherently more attractive to the Homo Sapien eye. Back in the days of Helen of Troy, Phidias, Plato and other great philosophers all observed the golden ratio, "a sum where the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one". Confusing? Let's apply it to the human face only: the features of the human head were measured in calculated, precise proportions to d...

Video game ranking site VGChartz reports that Mike Leyde, a 56-year old steel contractor from Riverside, California, has broken Bejeweled 2's scoreboard with a score of 2,147,783,647.
This method is easy, intuitive and requires very little math. You will need:
If you thought the last post on Two Circle Wobblers was wild, then wait until you see what happens when you build wobblers out of two half circles or two ellipses. In both of these cases, the center of gravity still remains constant in the vertical direction, allowing them to roll down the slightest of inclines or even travel a significant distance on a level surface if given a push or even when blown on.
I just found out that I might be expected to tip all the vendors... on top of the exorbitant fee they charge! Sigh... Here is a great tipping cheat sheet courtesy of theknot.com.
As you may have seen in your city or town, red light cameras are on the rise in the United States. In many instances in my area, these cameras have sprung up seemingly out of no-where, and mostly without any reason. Over use of these systems can make privacy (even on the road) a fleeting possibility.
I'm pretty sure that it's a universal dream for everyone in the world to retire early. Who wants to to be stuck with the rest of the country and retire when you're almost 70 years old? You heard me right, 70! Most people can't go out and do the things they love to do by the time they're 70, unless they've been practicing good health and exercise their entire life.
Always falling asleep behind the wheel? The National Highway Traffic Safety Administration (NHTSA) estimates that there are over 56,000 sleep-related accidents each year, resulting in 40,000 injuries and 1,550 deaths annually in the United States. Don't want to be a statistic? Then you may want to try out ASP Technology's mobile application which aims to keep you awake when you're fatigued on the road.
This one smells like a fish story. It is not. Tuesday April 13, Dave and I got up to surf westward at 7 in the morning. First rate waves. Headache cold water....sun blocked by the cliffs. Fast, clean, beach break. 3-4 foot sets, mostly lefts. About 15 dolphins swam by. Blase blase. We always see dolphins. But then some bigass whale with barnacles breaches. We are speechless. It is about 20 feet from us. We follow it for about thirty seconds and pinch ourselves. Have-you-ever? No...

What is a Data Structure?
The DIY industry is booming, despite the desperate blackmailing of society by finance capitalists. Companies like Adafruit and Makerbot are grossing well over a million dollars a year, and Evil Mad Science Laboratories just recently dedicated themselves to running a full-time kit business. Making kits is fun, but starting a business can be scary. If you already enjoy making gadgets and want to take the plunge into selling your own kits online, this article is for you.
Everyone's been in the following situation. You're sitting there at a nice bar, chatting up a smoking hot member of the opposite sex when all of a sudden they drop this bomb: "Can you engrave on wood in Photoshop?" The next thing you know, the night spirals into blackness and you wake up in a puddle of your own tears with some half-eaten beef jerky hanging out of your mouth.
Does this video prove that otherworldly intelligent life has visited Earth? No. It does not prove anything other than there are designs ‘etched’ onto the surface of a field. Does the video immediately above prove that otherworldly intelligent life hasn’t visited Earth? Yeah, you saw it coming; no, it proves nothing more than humans are able to ‘etch’ designs in a field of grain.

This week, Google held back on introducing a slew of new Google+ features, and introduced new Chrome extensions instead. The new additions won't replace of your favorite Chrome extensions, but they are very useful, and elegant.
Sounds like a false promise à la infomercial or typical spammy web headline—how can a 4.8 ounce gadget aid in weight loss? But, in truth, "who" better to act as a dedicated personal trainer and nutritionalist than the iPhone? The smartphone is completely and utterly tethered to the daily life of the average middle to upper class American. It's reliable and exact. All it needs is a charged battery, the right app, and of course, as with every diet and fitness regime, a user with unwavering self...
There's gonna be a rumble.... For this week's GJ article, I thought I would jump right into talking about a mortal-lock favourite of mine: West Side Story. If you haven't seen it (and a lot of folks havent - dudes especially) and you want a lesson in filmmaking craft from a bonafide master then you kind of owe it to yourself to rent this undisputed gem.
Join the Pilot program and learn how to fly! But you're not going to be flying airplanes in this Pilot program, you'll be trying your hands at Google's first laptop computer.
Imagine you're in Paris and you need to get to Versailles. Looking around for directions, you come to a cold realization—you do not speak a lick of French! How are you going to get to Versailles and what happens if there is a detour? It will be a difficult struggle, and you'd probably get lost and eventually fail. This is why it's important to know some of the country's language before taking that trip in the first place.
In the first part of this series, we learned about darknets, as well as how they came about. But these patches of forgotten Internet are not the oasis of free information you might think. Despite being hidden—or just harder to come across—these networks are no more safe then anywhere else on the 'clear' Internet. The nature of networking and routing means your location is always known in server logs. It only takes one phone call to your ISP with your IP address to obtain both your physical ad...
Welcome to Minecraft World! Check out our advanced tutorials and come play on our free server. There are many amazing redstone builds, but probably the pinnacle of redstone technology is the redstone calculator. The ability to turn simple game mechanics into a real-life calculator is one of genius, pioneered by some very clever Minecrafters many months ago.
Briefing Playing cards are used to play Killer but Killer is not exactly a card game. You cannot play this game if you do not know how to wink. I do not recommend that you go about winking at men and women to practice for this game.
Facebook unveiled a lot of changes last week, and, as usual, it's causing a lot of consternation and controversy. People within my Facebook, and on Google+, keep asking how to remove the ticker, and are trying, and mostly failing to make sense of the changes.

It could be said that the World Cup really starts during the knock-out stages. What was going on for the last couple of weeks was more like the "World's Soccer Fair." At least I'd like to think of it this way after watching games like Slovenia vs. Algeria, New Zealand vs. Slovakia or Cameroon vs. Netherlands (where Cameroon had no chances at all) and Brazil vs. Portugal with both teams qualified for the next round. I'm not dismissing any of these teams, since after 4 years they all merited to...
Introduction Halo: Reach is Bungie's latest and final addition to the franchise. Microsoft has claimed the title and from now on 343 Industries will be working on the Halo franchise. In my opinion, Bungie's last game is the best out of all of them. These are some tactics and bits of advice that I've picked up.
