They really dont need acceleration during the transfer, they just need a great enough inital velocity to escape. If its not great enough, your right, theres not much of a chance of it getting out to a further orbit.
I am not sure if this would have any effect, but what about if its initial orbit was highly elliptical, and it used a type of 'sling-shot' boost off the sun or an inner planet?
Remember those stories about finding lunar and martian rocks down in Anartica? Those come by a process called interplanetary transfer.
When an impact happens on a body, the crash sends debris up, sometimes with enough force to exit the gravitational pull of the planet. Through interplanetary transfer, that debris may land on the Earth, or really anywhere else in the solar system.
The process also works in reverse, if the Earth was struck by a large meteorite, debris would fly up and exit the Earths gravitational pull. This is similar to the process that formed the moon.
If there is a chance that bacteria from Mars can land on the Earth, then there is a chance that bacteria from the Earth could land on Mars. DNA is a little bit of a stretch, but with the scales and timeframs you work with in Astronomy, it is possible.
A DNA description or sample from every species on the Earth, that may never happen. There are too many genetic mutations that are constantly happening. DNA is to variant to have a complete catalog.
More likely, I think, is that some basic structures of DNA will survive. In the end, DNA is just DNA. All DNA is made up of nucleotides that are stung together to form long strings. This gives DNA have some common properties, and thats probably already whats up there.
An interesting side thought, we have interplanetary transfer, could there be such a thing as inter-solar-system transfer, or maybe even inter-galactic-transfer? The physical laws stay the same, just the scale and timeframes change.

I seem to remember this exact situation happening to fellow students, right around 94, and this was a common practice problem for our CS class.
I do remember the hardest part of this program was multiplying two arrays each size n. I seem to remember that we had a very quick algorithms to square a number in large array and add two arrays. I remember solving it with these in a manner of factorial=n(n+1)=n^2+n.
Anyway, those were good times.

On most of the pictures that have been released of saturn, it looks like the picture has been flip-flopped horizontally (the left-side is on the right and right-side is on the left). At least to me that is.
When viewed from above, planets orbit counter-clockwise. Cassini's tragectory also follows the planets counter-clockwise orbits.When Cassini approaches Saturn, it will be coming in from behind the planet, it is trying to catch up to it. This means the Sun will be on the left side of the picture, and the dark side of the planet will be on the right.
There are only two reasons that I can think of to explain why the sun in these pictures is coming from the right side.
1) Cassini is actually in front of Saturn.
2) The image is flipped to make the image more asthetically pleasing. Maybe the rings look better this way.
Now that this has been done, I wonder if it will lead to hacking/modding other Linksys routers. I have a BEFW11S4 (4port with 802.11B) which I've been wanted to add a few extra features to for a while.
Since they are both Linksys, I wonder how close their design, code, chipset are.
Rand McNally seems to give the best driving directions.
Their shortest route feature is unparralled from any other site that I've found so far.
Mapquest and Yahoo do have a shortest vs quickest route choice, but it seems as if they still go by finding the closest more significant road algorithm. It seems mapquest searches a little more in depth for finding the shortest as the bird flies algorithm.
First, I cant imagine how anyone could unintentionally subject themselves to an environment without a word processor. I didn't believe a story like this would be possible these days.
Two years ago, however, I went on a sabbatical from computers. I had enough of CS and wanted to spend some time out and about with friends. After finding out that pen writing was a bad choice for me, I researched typewriters (the movie Naked Lunch helped quite a bit). A good old Royal typewriter can really do wonders and even make you want to write again.
I tried several typewriters, and gradually I learned what to look for in a typewriter.
1) Keyboard and button size, make sure they are comfortable. Same rules for a keyboard.
2) Availability of ribbon, does someone still make a replacement? I've had to respool several ribbons onto the old spools to make them work.
3) Weight of keys, how much force does it take to activate a key. I light a heavy key for its momentum, they leave a nice dark imprint, but it has to be balanced very well, otherwise it takes a lot of force to get it moving.
4) Key return, how fast a key returns to a safe or resting position, a quick return is good but can add more force.
5) The Mechanics, are the keys likely to hit each other while in action? Are they equally aligned both horizontally and vertically?
6) Physical Properties - A Heavy typewriter is good for home use. A later 70's plastic briefcase style typewriter might be a little better for travel, for when you want to write that novel or code at a coffee bar.
Every typewriter is a little different so it may take a while to find a good one. However, these days, its sometimes easy to pick one up for $5 or $10. Just hearing the clickity clack of the keys is enough to inspire one to write.
I've been wating this for a long while now. For us slashdotters that are looking for jobs this can help. I've been able to do a search for employment for my city. It came back with some sites that I had would never of found before.
Looks like a few people were knocked off line.
Look at the Internet Traffic Report site. I wonder how else the net was effected, and if there are any other sites that would reflect this.
Watching nightly news on one of the major networks, they actually discussed this topic, and that the outage could have been done by hackers.
The gist of the discussion came from that 3 weeks ago Power Authorities met and acknowledged that there was a security threat from their systems connected to the net. During that meeting, they set up some new guidelines to regulate the software that controls the power grids to make them more secure, and to take them off the internet. He said, however, those new regulations had not taken affect yet.
Now this is a far stretch, and I think they even acknowledged this, but nevertheless the topic was discussed.
Another possibility they said that could also of happened, instead of computer hacking, radio hacking. The power control centers are connected by radio, and it wouldn't be hard to override those signals.
Interesting thoughts, but I still doubt these possibilities could ever happen.
I work in the cell phone industry. From what I've seen, Nokia offers the most accessibility for developers wanting to write Java applications for phones. For several months now they have released SDK's and Development Suites. Looks like these would be farily easy to learn.
I'm not sure if Java applications will have access to items like the phonebook, or if they would be able to dial calls. I seem to remember they won't, its a security measure to make sure applications don't dial calls which could be charged for your bill (I didn't make the call, my hone did). I do believe, however, they would have limited access to hardware features such as a keypresses and the screen.
Customers do pay Symantec to protect their networks in every way possible. If they told a few customers first, thats great for them, they are a business and the higher paying customers probably appreciate that.
I am wondering though, if they had spread the word earlier (assuming they knew earlier), could non clients have patched their systems and reduced the effect that the worm caused on its paying customers systems.
