So I have kids and I am constantly looking for fun, educational, entertaining, games for them to play.  I like discovering open source free applications that satisfy this most of all.

Some examples of great programs: tux paint and tux typing.

Phun is different.  Where those two programs excel in teaching kids, Phun is just fun.

It's interactive in a way that not many programs are.  It actually has the playability that feels much like an RTS.  It does what you make it do now.  You add something and the environment acts upon it.

Watch this video.

And it's a toy...except it isn't: 

Radial engine:

Gears:

It's a remarkable achievement.

One big benefit I see in Phun over the other kid applications I've found is that Phun uses an almost standard application user interface.  The user needs to navigate menus and toolbars and context menus.  The other kid apps focus on learning something or doing something.  Phun does that also, but because of its complexity the standard UI is leveraged as the simplest solution.

This is a great side benefit.  Kids get exposure to the standard UI and how applications work.  This has direct impact on any and all other applications they might encounter.

If you have kids go get this program now.  Install it, run it and watch your kids be sucked in for hours.  Heck go do it yourself.  It's really addicting.

Check out this cool demo for the Prius' main gear.

There is a simulation at the bottom of the page that let's you vary the input parameters and watch the gearing adjust.

The PSD is a planetary gear set that removes the need for a traditional stepped gearbox and transmission components, and also the familiar rev-lurch-rev-lurch of acceleration in an ordinary gas powered car. It acts as a continuously variable transmission (CVT) but with a fixed gear ratio.

Cool stuff.  They need to get their car designers to work on the car though because it is the ugliest thing on the road...well maybe that Pontiac Aztec thing was uglier, but it's close.

The much maligned International Space Station keeps moving forward oblivious to its critics.  Yesterday the Shuttle Atlantis blasted off with the Columbus Module aboard.

The Columbus module is another science module with the ability to hold 10 racks of scientific experiments.

It is growing and finally becoming a significant platform in space.  I understand the critics that deride its lack of strategic space location.  Its in-between-ness that doesn't help us much to get anywhere else in the solar system.  I understand the critics that bring up the ROI on a manned space station and compare it to one of our probe missions like the Mars Rovers.

I understand all that.

But I believe it provides other benefits:

1. It teaches us how to construct complicated things in space.  What we are learning from the ISS will be crucial for ANY construction we do in space and if you think there won't be much call for that...well I disagree with you.
   
   This has been done over a period of years.  From a broad base of contributors spanning continents, languages, governments.  It's remarkable.
   
2. We continue to learn how to make livable habitats for humans in space.  We need to have this sussed if we are to do any sort of long range trips in the future - Mars anyone?
   
3. There ARE science experiments that can only be performed by humans in space.  The trick is identifying them and prioritizing them.
   
4. It is a manned presence in space.  Do you realize if things just stumble along like this for another 10 years or so that we might enter an era where mankind will always have a representative in space.  And in my opinion there will be increasing numbers of extra-terran humans as the years go on.  Too many people want to explore "out there".

I also think it is flippin' cool.  And in the grand scheme of government and society expenditures the entire space programs of all the world are hobbies.  NASA has had a 12-15 billion dollar budget since the 1980's.  Through all that inflationary time, where the value of its dollars has steadily decreased, it has maintained the program and accomplished significant things.

It will be fascinating to see if the burgeoning commercial space programs will interface with the existing governmental ones.  Stay tuned...

Update: The final volume of the ISS is going to be approximately 1000 cubic meters. It is more than half done but for the sake of argument let's say there is 500 cubic meters of livable volume in orbit right now.

Well according to the awesome intertubes a standard 40 foot shipping container has 67.5 cubic meters of volume inside it.  That means there are the equivalent of 7.5 shipping containers of habitat up there right now and in the end there will be approximately 15 shipping containers of habitable volume (a little less actually but close enough).

Now that is amazing.  The space boys and girls aren't just whistling Dixie.

...Commercial...Space...Station...

Look, I don't mean to keep talking about all this accelerating change and stuff, but I really think we're on the verge of something here.

1. We have Virgin Galactic releasing their spaceship design and preparing for launches at some undetermined time.

2. We have SpaceX developing a new cost effective rocket system with the intent to be the only ISS supportable US based space system at the time the Shuttle fleet is finally grounded.  They have already had two launches and have several scheduled this year.

And now this news from Bigelow.

Bigelow Aerospace and Denver-based United Launch Alliance (ULA) have been working together for over a year studying what it would take to human-rate the Atlas 5 rocket. Industry sources said Bigelow Aerospace is ready to place an order that includes six launches starting in 2011 to begin assembly and early operation of the new station.

We live in unprecedented times in so many ways this is merely one more manifestation of the change that is taking place all around us.

If the X-Prize worked to get the private commercial space race kicked off and it was only $10 Million, what would a payout of $1 BILLION do for results. 

This is an ambitious set of problems laid out by the Victory Project. 

To the first person(s) that solves any of these Problems:

1. Develop a cure for breast cancer.
2. Develop a cure for diabetes.
3. Reduce greenhouse emissions from petroleum powered automobiles by 95% without increasing the cost of a normal car more than 5%.
4. Achieve 150 miles per gallon of gasoline in a 3,000 lb. car, using EPA standards; without increasing the cost of a normal car more than 10%.

Is it big?   Yes.

Is it different?   Yes.

Will it work?   Yes.

This is inspiring.  But some of these might take the full Billion dollar prize to develop.

They're looking for donations, feel free to contribute.

Pretty cool. Here's the project website: Autonomous Foosball Table

They were hindered by some hardware limitations.  Still like I said pretty cool.

We here at techRivet pride ourselves in our commitment to bringing our vast reading public only the most innovative achievements and inventions dealing with important technically problems facing us in the world today...

Then we find something like this and just marvel at the innovation, creativity and purity of mind that it took to create it.

300 hp V8 engine...Chainsaw!

Quantum chip rides on superconducting bus

The connection of two Qubits on a chip for the first time.  This is a crucial first step, a proof of concept, that will lead to true quantum computers.

In effect, says Johannes Majer, a member of the Yale team, the researchers have created "a quantum bus". A bus is used in conventional computers as a conduit for information among the various components – but its quantum chip equivalent has never been made before.

With the predictions for the end of Moore's law I refer you back to Ray Kurzweil's great essay on accelerating change that stipulated the doubling of computing power was not bound to the integrated chip.  The phenomena both preceded the integrated chip and will in all likelihood continue after the silicon chip is no longer viable.

The creation of a working quantum computer might be as momentous an event as the creation of the transistor.  History will of course judge.

I wonder if this is a modern solution...by that I don't mean modern as in tools but modern as in thought.  This is an ingenious technique but I just wonder how ingenious pre-historic man was.  I mean I think it far more likely that brutish multi-man methods were used rather than this elegant technique.

It's still cool though.
