A a single data point, I spent an hour cleaning the K worm off my laptop after a co-worker lent me his memory stick to transfer a file.
Cost - An hour of pay plus the frustration of directly not getting important tasks done.
The articles seem to state specifically that the drilling in Europe caused the earthquake. Almost without a doubt that is just a conjecture.
The problem in California is that if the drilling takes a year or two, there is bound to be some kind of quake, and the drilling
will get the blame.
On the other hand, the value of deep well geothermal is so great that it would be worth a minor quake to get it.
I noticed in the NASA description that the heat shield is exposed for the first time during the mission, when the service module is jetisoned just before reentry. This is an obvious plug at the problems the shuttle had with heat shield material.
They also have seperated the people from the cargo so the people ship can be more reliable, and the cargo ship can be less reliable, e.g. the solid fuel boosters.
Strapping solid fuel boosters to people has never been a good idea.
The reason you are healthier is because you are eating a better diet than before. If that better diet happens to be a no-animal diet then you are confusing cause and effect. I went from vegetarian
to meta-atarian and felt much better and healither. Most people, when they discover any 'health food' diet, feel much better simply because the diet is better than the junk they were eating.
At this time I believe that a hunter-gather paleo-diet (PaleoDiet) is the best suited for Homo Sapiens.
I very much agree that 'Milk is an Unnatural'®.
Golly! I see none of that. OpenOffice works fine
for me and I am immersed in a MS world. There are a few minor quirks, but there are also quirks in MS Office. It sure is nice not to have to worry about
licenses and such. And yes, it uses lots of memory, but then it does lots too. MS Office uses even more memory.
Nope, it only raises the data use for a short time. Once the spamer stops and the site dies we gat back that bandwidth plus what the spammer was wasting.
I noticed the 10 per person quote too. It is wrong.
There are something like 6 Billion people in the world. IPV4 is 4 billion addreses.
The huge space of the IPV6 address is 18 Million Billion addresses.
This is 3 Billion addresses per peron.
They must have meant 10 whole internets per person or something, but it is realy about 1 internet per person.
The previous project in C had much more control and persistence on the clients doing the computing. This current project had much looser volunteer work and ini fact was done on alot less computers. The java program is faster than the old C++ because it is running on MUSH faster hardware. Java is platform portable. That is why I used it.

My most sincere appologies. I had so many emails that I couldn't reply to them all. I ended up putting the code on my web site, which is what I should have done in the first place. This is the first time I ever posted to slashdot and it was a learning experience.

Actualy the network computing started with many people rendering the image and after a month only about 5 or 6 people were following through and still rendering. Unfortunately I didn't put in a counter for cumulative CPU hours.
This is one of the few sensible responses. You are exactly correct. The email was a bad idea. I will be posting it on my web site soon.
I may try to automate the upload. The problem is that the result data set is 20Meg and i am worried about the upload time on a 56k modem. I may put an 'upload' button so it happens when the user decides it should.
I have received about 900 emails today.
I will be posting the program on http://www.cpjava.net in a day or two so everyone can download it.
Not to self: don't post email address:-(
Im learning my lesson the hard way on this one. I should have (and will) posted the cpjava.net site and then let everyone download from that.
Apparently posting my email was not a good idea. The response has been way more than I expected.
In fact in 1994 the SIGGRAPH moderators rejected the article but published the picture.
The reason I did the rendering in 1994 was mostly
"because it's there" and had not been done before.
So why do it again now? First of all, "because it's there". Second, there are a new breed of graphics cards comming out soon that will do ray tracing in hardware. This brute force approach may not be so far fetched.
That is correct. There is almost no extra cost in extra cameras or extra focal planes. I chose three so that the returned results are not too large. In fact you could simply record every photon that hits a wall, but the results would be huge.
I will be combining the result in a graphical tool that lets me look at each submission
before it gets summed into the result. This will at least prevent some pr0n picture from getting merged in. Also a few bad submissions or duplicates will not throw off the total results.
The old 1994 picture is of a cubic room with mirrors on the near and far walls. The 'bubbles' are refletive spheres. A beam of light comes out of the left wall, hits a prism and forms a spectrum on the right wall. The depth of field is very shallow so
only objects exactly on the focal plane are in focus.
The black fuzzy blob is the camera aperature, out of focus, being reflected in the far mirror.
There is an error in the image. The corners of the room are bright and should not be. This is due to a poorly chosen diffuse scattering model.
The current project is an almost identicle setup, with 1/4 as big of aperature. I have done about 1 billion photons on my 3 computers, and the new image looks much cleaner.
I expcet it will take about a trillion photons to make a realy smooth image.
Prevayler addresses a certain class of problem, the small application with a simple database.
It does not address the same problem space that a relational database does.
The problen space for prevayler happens to match several projects I am working on. They have the properties of a small database, single instance use, and load-all-and-flush-once-in-a-while. This
matches pretty well most small web applications. If you look at.NET and C# the approach there is to load the entire database into memory, and flush the changes. This was chosen by the Evil Empire because it meets a certain need and class of web site application.
I think that the rhetoric on the prevayler web site is a bit extreme, and may not be in the best interest of the project. The comments on slashdot are much more extreme, and rather insulting and poorly thought out.
I, for one, am glad that Slashdot carried the article, and am thankfull for the team that wrote prevayler for making it open source. It
is a good solution for a certain type of application.
Prevayler is a horrible solution for some other types of applications where an RDBMS is appropriate. If you need the advanced capabilities of SQL than by no means should you use Prevayler.
Once 64 bit Java VMs become common, then Prevayler will become appropriate for a broader class of application. Even then there will be some applications that need the features of a RDBMS. Maybe at that time Prevayler will gain more features that RDBMS's have, and probably be wrecked by code bloat. Lets just hope that Prevayler keeps it's simplicity and keeps targeting the application space it was intended for and does not try to compete with RDBMS.
So, why all the harsh comments? Perhaps the people making the harsh comments simply never created anything usefull in their lives, and are attempting to agrandise them selves at the expense of others. My advice to them? "Get tharapy".
Or better yet, the best tharapy would be to actualy work on an open source project and see just how difficult it is.
My kid was running through the room, tripped on the network cable, and yanked the entire desktop unit off the table.
It bent the heck out of the case, but the computer still works. It's just a bit lopsided now and the outer cover won't go n correctly.
I bought my kid a 200-in-one electronic kit from Radio Shack. It is realy nifty and does everything from A to Z in electronics. Radios, Buzzers, FlipFlops, LED Lights, and has a generic breadboard in the middle.
For $50 its a great deal. I wish I'd had one in college when taking EE courses.
