NASA Solar Probe Blasts Toward Rendezvous With Sun 90

coondoggie writes "NASA this morning used a United Launch Alliance Atlas rocket to blast its 6,800lb Solar Dynamics Observatory into an orbit 22,300 miles above Earth. The $808 million spacecraft will ultimately study the Sun and send back what NASA called a prodigious rush of pictures about sunspots, solar flares and a variety of other never-before-seen solar events. The idea is to get a better idea of how the Sun works and let scientists better forecast the space weather to offer earlier warnings to protect astronauts and satellites, NASA said."

Which might make for some interesting theoretical attacks -- if I can craft a block with the same hash as a block I'm interested in, I can read the contents of the other block.

// Assume that an information-leak bug that allows the attacker to read the hash values and other metadata necessary, which is entirely possible.

It's funny.  Laugh.

Treasured "Moon Rock" Is Petrified Wood 209

Hugh Pickens writes "BBC reports that a treasured piece at the Dutch national museum — a supposed moon rock from the first manned lunar landing given to former Prime Minister Willem Drees during a goodwill tour by the three Apollo-11 astronauts shortly after their moon mission in 1969 — has been revealed as nothing more than petrified wood, curators say. A jagged fist-size stone with reddish tints, it was mounted and placed above a plaque that said, 'With the compliments of the Ambassador of the United States of America... to commemorate the visit to The Netherlands of the Apollo-11 astronauts.' The plaque does not specify that the rock came from the moon's surface. Researchers from Amsterdam's Free University said they could see at a glance the rock was probably not from the moon. They followed the initial appraisal up with extensive testing. 'It's a nondescript, pretty-much-worthless stone,' wrote Geologist Frank Beunk in an article published by the museum. Beunk says the rock, which the museum at one point insured for more than half a million dollars, was worth no more than $70. The 'rock' had originally been been vetted through a phone call to NASA. As the US Embassy in the Hague said it was investigating the matter, the Rijksmuseum says it will keep the piece as a curiosity."

Then your company would likely frown on you working around that by indirectly syncing the personal machine as well. The technical measures in place that prevent you from connecting your laptop to Exchange are merely a way of enforcing policy. You're still violating the policy even if it doesn't stop you.

I don't give a shit, but I bet your company would.

I mostly agree with you, but ADB made it all the way from the Apple IIgs [1986] and IIc+ (6502/65816 CPU with Apple II OS), Mac SE (68000, System 5 or later), up through the beige PowerMac G3 [1998]. That's about a 12 year run. Even beyond that, it apparently was still used for internal keyboards on laptops until the Intel switch.

If you think we *want* to be stuck on IE 6, we don't. We don't really care. However, the developers wrote some asinine ActiveX shit that doesn't work on IE 7 or IE 8, and sure as fuck don't work on Firefox. Or, we're using PeopleSoft software that isn't certified on anything about IE 6, etc.

For XP? Well, by the time Vista was working well enough with the internal apps to roll out, Windows 7 was in beta. Why the hell would I go through upgrading everything to Vista just to have the same people turn around and want Windows 7 next week, but we can't afford to have any departments down for a day to reimage.

It comes down to the golden rule of the sysadmin -- if it's working, don't fuck with it.

I've dealt with enough developers that I'd say about 1/2 to 2/3 were competent, and some of those, while competent developers, didn't have anywhere near enough knowledge to be allowed to administer their own machine.

Of course, I'd probably say the same about 1/2 of the sysadmins I've worked with as well, and very few sysadmins have the knowledge to be competent developers. The higher percentage of incompetent sysadmins stems from not understanding security, or not understanding how to balance security with usability.

Note my use of the word knowledge -- most developers could be competent sysadmins, but don't have the knowledge base. If you're developing database-driven web applications using .NET, how likely are you to need to know details of filesystem ACLs, or how a rootkit may insert itself in to a OS kernel? How many sysadmins are going to know how to write (or even use) a database stored procedure, and more importantly, /when it's appropriate to do so?/

Unfortunately, most people don't have the wisdom to understand where their own knowledge ends. I understand quite a bit about a lot of topics, but I'm willing to let an expert (doctor, dentist, mechanic, athletic trainer, etc.) do their jobs. Why don't people have the same attitude about sysadmins? (Hint: I think it's because when you fuck up your car, you pay to fix it. If you fuck up your PC there's no direct financial penalty for you personally.)

It's not "one minute out of work."

You're focused on a large, complex problem. Someone interrupts you, and you have to go deal with them. When you get back to the large, complex problem, you lose a lot of time figuring out where you were and picking up the pieces of the troubleshooting.

That's not even factoring in that your co-worker called the help desk, someone there had a write a ticket, send it to a deskside support person, who had to leave their desk, come down, and do the "one minute" fix. Total time? Probably more like 30 minutes where your co-worker wasn't working.

I agree with one of the other posters -- I would have had *your* ass. Sending an email to the entire company to apologize to the tech? That's a cannon to kill a gnat -- but don't forget that you're the gnat, asshole.

If you really think the sysadmin is making the decision to block flickr, I (hope and expect) you're wrong. Generally, it's some asshole who's spending his day looking up nudists on flickr, someone else sees the monitor and complains, and because the asshole is the manager's nephew/golf buddy, the problem is that flickr.com was allowed -- tell the sysadmins to block it.

Even without that contrived scenario, if they're using a third-party service for the filter, like websense, you block a category -- porn, blogs, social networking, sports, gambling, etc. Because flickr has plenty of NSFW images, filters may include it in the porn category, as well as social networking (comments, friends, etc.)

If the filter is blocking it by default, in a non-work-related category (porn), how will you justify *un*blocking it?

Which OS Performs Best With SSDs? 255

Lucas123 writes "Linux, Vista and Mac OS perform differently with solid state disks. While all of them work well with SSDs, as they write data more efficiently or run fewer applications in the background than XP, surprisingly Windows 2000 appears to be the winner when it comes to performance. However, no OS has yet been optimized to work with SSDs. This lost opportunity is one Microsoft plans to address with Windows 7; Apple, too, is likely to upgrade its platform soon for better SSD performance."

Inventor Builds Robot Wife Screenshot-sm 469

Inventor Le Trung must really like the book "The Stepford Wives," because he has built the dream of every lonely man without hope, a robot wife. Le's wife, Aiko, starts the day by reading him the newspaper headlines and they go for a drives in the countryside. Le says his relationship with Aiko hasn't strayed into the bedroom, but a few tweaks could turn her into a sexual partner, even redesigning her to have a simulated orgasm. *Shudder*
