It's not the data in the files that caused problems, it's the number of individual files. Imagine your app has 100k allocated for listing the contents of a directory, and the directory listing was 150k. That's the problem they are having, although much simplified. By deleting the files, the problem goes away, and they can prevent it in the future by clearing out files once they are downloaded to earth, so they don't accumulate so much over time.
Well it's not as risky as it sounds, the memory they are wiping is secondary storage and doesn't contain any of the OS. It would be like formatting a floppy or erasing a cdrw, they will lose the data that has been saved their since the mission started, but they aren't risking any of the OS itself.
actually that's not true. The degradation is caused by a chamical reactuion with oxygen in the air, not by the read laser, so they can be watched as much as you want, for about 2 days.
The bug they are talking about with IE allows you to put ANYTHING in the address bar. With your example, you are just keeping your domain name in the address bar, but with that IE bug, you could keep them on your site but make the address bar say http://www.microsoft.com
That's a good attitude, if you can't solve the whole problem don't do anything at all...
This isn't about blocking every spammer. Blocking port 25 outbound will stop infected PCs from sending the virus out to other people. Legit mailservers will have no problem, they just have to relay through the ISP's mailserver, which is simple in any MTA.
So, they aren't hurting anyone. They are stopping viruses from spreading. What exactly is the problem?
If you ask me, a virus that does some damage to the person who runs it is just what we need, all these pansy viruses we have now just spread and do stupid shit like ddos sco. If there were some viruses around that nuked some critical files after spreading, people would quickly learn (some of them anyway). It would also give mailserver admins more incentive to filter attachments.
Yes, that's obviously the way around it, serve the image yourself instead of just linking to it. That wasn't my point though, my point was simply that when you DO link to an image in someone else's site, you can't make clients visiting your site send a forged referrer to the site you linked from. Unless there was an IE bug like the one that lets you mess with the url in their location bar.
Except that they don't have to send the requests all from 1 ip address. These are spammers we're talking about, the same people who use PCs hijacked by windows worms to send spam. It wouldn't be much of a stretch to proxy their signups through hacked machines.
Besides, if multiple requests from one ip were all it took for the free email servers to deny someone, we wouldn't need catchems in the first place. The problem is there are often large numbers of people coming through single ip address, such as corporate proxy servers, nat ips, ISP web caches, etc.
The referer is easily forged by clients, but it's not something that another webserver could manipulate on the client side. I couldn't link an image from your site within my site and have clients visiting my site spoof the referrer. Well, maybe if the clients are using IE, but that's anothore story.
The spammers don't have to link to the original image, they can just copy it and serve it from the porn site. If done correctly, the free email server would never see anything out of the ordinary.
there is no way for the pornsite/spamscript to verify the input of the user
Sure there is, they just have to finish the signup attempt for the free mail account and not give results to the user until they see the results of the email signup. To the porn site luser, this would just look like a 1 or 2 second delay after hitting submit.
Take a look at the size of the external fuel tank and booster rockets used to launch. You'd to bring need a similar amount of fuel with you into orbit to land in the way you described. Carrying that much, you now need an even bigger (much, much, much bigger) tank and boosters to get to orbit in the first place. It's also more difficult to control, adds alot of complexity to the system, and still requres an unpowered emergency landing plan. It adds up fast, powered descent is just not a viable option.
We go from hearing next to nothing to now hearing something "new" just about everyday.
I wonder if that would have something to do with the fact that both missions from both NASA and the ESA just reached mars and a 3rd will be there saturday. What a coincidence that nasa would start releasing info at a time like that! BTW, it was the ESA's mission that proved there's water, not nasa.
Imagine a large asteroid hitting mars. There will be BILLIONS of pieces sent into an orbit similar to mars, many of which will then be gravtationally tossed into other orbits by mars itself. It's not hard to imagine many many of these eventually landing on earth within the billion years or so since then.
There are alot more than 6 pieces that have been found, these two people just happen to collect ALOT of meteorites and happen to know how to recognize a martian one. Of course it sounds like too much coincidence to be true when you think only 6 have hit earth and all been found by the same people, but in reality thousands and probably millions have hit earth, and many have been found and not recognized for what they are. It only makes sense that the people who know how to recognize them would find the most.
Halo orbits will only keep the object stable in the plane perpendicular to the line between the earth and moon, any displacement out of the plane will need to be corrected still by rockets. IMHO, this is a perfect application for ion engines, making minor orbital corrections in geosync and lagrange orbits.
Yeah, it's you could prove to the conspiracy theorists that the flag you brought back was actually on the moon for the last 30 years and not something you just brought with you this time. Besides, if we're going back, why would we go the the same places again? It would make more sense to explore new ground.

Both.
They have extra shielding on the outside, and the electronics on the inside are designed to disipate sudden charges created by radiation hits.
I've never seen an ISP who both forces you to use their relay and restricts you to their domain.
didn't you see the movie? the fifth is a hot chick with orange hair.

The best part is I've never seen one that send the headers back so you can see where the actual message came from.

Hey, there are all the conspiracy freaks now?
I bet they're busy writing up a description of how NASA faked this failure to make their staged landing more realistic...

Plus, the domain name itself has nothing to do with the work on the site.
Every single image taken by the rover (raw and not even combined into color images) is available for download from the mars rover website. Check here.
How did that get modded up? The conspiracy bitches complain about the color correction then complain more when it's explained in too much detail?
Not to mention that this mars mission was planned before GWB was even 'elected'.
