Dropbox

Dropbox also saves revisions of files. If you save your work regularly (or use auto-save), you can go back to an earlier version of the file. This can save you from wiping out your work in Word or even recover an accidently deleted file.

Dropbox also does file sharing. My wife and I also have Dropbox accounts and it was easy to set up one folder that’s shared with the entire family. Now when our daughter wants to show us something, instead of emailing it to us, she can just copy the file to the Family folder and we all get a copy on our computer. We also use it to copy files to the one computer that’s connected to the printer, since I haven’t gotten around to figuring out what’s wrong with the printer sharing on our network.

Dropbox can also share files online. By default, all your files are private and encrypted. But if you copy a file to your Public folder, you can right-click on the file and copy a web site link to that file.

Dropbox comes with a free 2 gigabytes of storage. You can upgrade to a paid account to get 50 or 100 gigabytes. If you use my referral link, we both get an extra 256 megabytes for free.

1. Take it easy on them. You don’t want to let them get away with making bad moves (that won’t improve their chess), so don’t just pretend to not see things. But you should intentionally make mistakes of your own and help them see how to take advantage of them.
2. Remove pieces from the stronger player. This is a traditional way to play chess with a handicap. You can remove as little as one pawn (and different pawns cause different problems) or as much as both rooks and the queen. This makes for a challenging and interesting game for the stronger player.
3. Switch places. Play through the opening and switch places once you get into the middle game. A good time to switch is right after they make a big mistake. Switch sides and let them figure out how to take advantage of their own mistake.
4. Let them make more moves to start the game. Give them two, three or four moves to start the game. They shouldn’t be allowed to move past the 4th rank as white (or 5th as black).
5. Use a clock. Give the stronger player 10, 7, or even 5 minutes while the weaker player has 30 minutes or more. Kids will still stress out and try to play fast moves, so you will constantly have to remind them to slow down and think.

But whatever you do, don’t let them take back moves. That’s a bad habit to start. They should still have to take back illegal moves, such as where a piece moves incorrectly or if the move results in check or doesn’t get them out of check.

The game is getting quite old, but it runs well on Windows XP. It does have some occasional glitches and it crashes on my PC about once every dozen combat rounds, but I’ve never lost a robot design or anything. I just have to fight a battle again.

The computer’s artificial intelligence (AI) for your computer-controlled opponents is fairly weak except for one particular robot, Emergency. Older kids and grown-ups will find good attack patterns that work over and over again against all the bots. This doesn’t take too much away from the game, but it is an oddity. The one tough bot, Emergency, is quite a challenge and shows what the game could have been. There are some hacks available on the web that will add more difficult AI for the other bots, but we haven’t tried them yet.

The multiplayer mode is difficult to keep working. We’ve had a lot of times where we just could never get connected multiplayer. Even if we get connected, the game often lags or loses connection. It’s bad enough that we rarely even try to run multiplayer any more.

The design and construction of the robots is the real winner in the game. The designer starts by drawing out the shape of the robot. Then components are added, usually starting with motors and wheels followed by weapons and batteries. Then the whole thing has to be wired up to work with the remote control system.

There are several types of motors, wheels, batteries, and different linking parts. Each has a tradeoff like weight versus power or strength. The different motors draw different amounts of electrical power so working out what type of batteries and how many of them is also a factor.

The weapons include ram plates, spikes, circular saw blades, hammers and axes. There are also pneumatic actuators powered by compressed air so a weapon can quickly thrust, if you have room for the air tank.

There are THREE different weight classes in the game which is how bots are categorized. Cost isn’t considered so you have an unlimited budget. In each weight class you face a different set of computer controlled robots, with different strengths and weaknesses.

It’s a great game for robot enthusiasts and even has some educational value.

1. Play with a clock. For some reason, kids love playing chess with a clock. A real clock is best, but in a pinch there are quite a few software clocks you can download for a laptop or PDA/smartphone.
2. Play Blitz. With only 5 minutes for each player, there is very little time to think. You get to play a lot of chess in a short period of time and get to make lots of mistakes to think about.
3. Play “the pawn game”. Only play with pawns, starting from their usual spots. Win by promoting a pawn or capturing all the opponent’s pawns.
4. Practice endgames. Set up just a couple of units in random spots around the board and play until a draw or checkmate. King vs. king and two rooks is a good starter, or a king and a couple pawns on each side.
5. Play Crazyhouse. On their turn, instead of moving, a player can add a new piece to the board to match ones taken from the other player. (Bughouse is a popular four-player two-board chess variant played at many kid chess club meetings.) There’s some debate about how much chess players learn from this, but it beats not working on chess at all.

Most chess books are aimed at the experienced player. Even the childish-looking How to Beat Your Dad at Chess is beyond beginning players. I’ve found three books that are excellent for teaching younger players: Chess for Children, Better Chess for Young Players, and Batsford Chess Course. The Chess For Dummies and The Complete Idiot’s Guide to Chess are also decent comprehensive books. Books by Susan Polgar, a female grandmaster, would be excellent for girls.

There are many excellent chess websites that offer articles, puzzles, and ways to play real opponents. One exceptional one for learning is ChessTempo, which dynamically rates players and puzzles so the player is offered puzzles at the appropriate difficulty. A bonus for kids is that you can see your score rise (or fall) as you work, so they continually get feedback on their efforts and can stay motivated to beat the scores of friends and family.

A great free chess tool is Winboard (and the bundled Crafty chess “engine”).  Whenever you can’t understand where a game went wrong, playing through the game with analysis turned on is a tremendous help.

We attempted to do it as a family last year but dropped out. This year, older and wiser, the kids are excited about doing it again.

EPGY has consistently exceeded our expectations with each of our experiences with them.

Stanford’s online high school adds grades seven, eight and nine

The Education Program for Gifted Youth at Stanford University will be adding three additional grades to its online high school.

Created in 2006 to meet the specific needs of gifted students, the EPGY Online High School (OHS) will add the seventh, eighth and ninth grades for fall 2009. Applications are currently being accepted, and classes for these grades will begin this fall. Full details are available at http://epgy.stanford.edu/ohs.

“The addition of these lower grades is particularly important, since this is where the frustration for these students so often begins,” said Cathie Wlaschin of the Malone Family Foundation, which provided an original gift of $3.3 million to launch the high school three years ago, and through the support of which the new grades are being added. The foundation provides scholarship endowments to select U.S. independent secondary schools to fund the education of gifted students with financial need. Through a separate program, the foundation also supports research on gifted education.

In the past three years, the EPGY Online High School has been fully accredited by the Western Association of Schools and Colleges and approved as an online provider by the University of California. Enrollment has grown from 30 students to 135, with students coming from 20 states and nine countries. Seventeen students will be graduating this year, with five entering Stanford University in the fall.

“It had always been our intention to be a full six-year school,” said Patrick Suppes, director and faculty adviser of EPGY and a philosophy professor emeritus at Stanford. “With students of this caliber, it is essential that they be identified early and put to work. The sooner they are fully engaged academically, the better off they will be.”
