Submission + - New Mersenne Primes Announced 1

Mini-Geek writes: GIMPS has announced M45 and M46, found September 6 and August 23 respectively. Both numbers are over 10,000,000 digits, having 11,185,272 and 12,978,189 respectively. The numbers are 243,112,609-1 and 237,156,667-1. M45 and M46 were discovered by Hans-Michael Elvenich and Edson Smith respectively. GIMPS will claim the EFF's $100K reward for the first prime number with over 10,000,000 digits. GIMPS will split the prize money by their prize rules, with $50,000 going to the discoverer of M46. The discoverer of M45 will not receive any prize money, since he discovered M45 after M46. M45 is 'the first Mersenne prime to be discovered out of order since Colquitt and Welsh discovered 2110,503-1 in 1988.' Read more about both new primes at http://www.mersenne.org/.

Submission + - The death of the progress bar? (slashdot.org)

Too-late-too-fight-boredom writes: As I sit watching a 3G iPhone absorb the latest 237.8MB upgrade (that's before unpacking, btw) I realise that here too is really no way of telling just how far it has progressed, and it struck me that I haven't seen a *real* progress bar for quite some time other than, ironically, on the iPhone itself.

Let me define "real": a progress bar that gives me an idea of how far a computer program has progressed during a time consuming (> 30 seconds) task. What I do NOT consider a progress bar:

- one that starts again after it has completed its journey from left to right (a "feature" of most newer installers, probably aimed at users busy)
- an animation that tells me nothing at all — demonstrated by what PC based iTunes shows when it pushes the aforementioned update up the iPhone's rear end.
- one that tells me it needs another 31456 hours and some minutes and then finishes 10 mins later (Vista).

Now, I understand that it's sometimes hard to predict just how long things are going to take, but then maybe an overview bar and one per task would be more informative. It's not like that is a new idea, if I recall correctly that was something used by the Norton Commander. If not, well, look at the Linux Midnight Commander — same idea. Useful.

I've seen enough "keep 'em busy" animation to last me a lifetime, starting with the animated Windows hourglass which mainly appears to suggest that the system you paid for is presently off doing something else like smoking a joint or copying some potentially confidential information, so I really don't need any more of that, thanks.

Just bring back the progress bar, please. I would consider that, umm, well, progress..

Submission + - Why Does Hurricane Size Not Get As Much Attention? 1

circletimessquare writes: "Hurricanes can vary greatly in size. As of Thursday Evening, Ike is a Category 2-3 Storm. But it is extremely large. Therefore, in terms of raw destructive energy, it is stronger and more dangerous than even Hurrican Katrina. A good comparison of raw strength, ironically on an experimental NOAA scale called IKE (integrated kinetic energy), quantifies this comparison. Anyone with a passing familiarity with physics understands a wind going 100 mph and 30 miles wide packs more energy than a wind going 200 mph but only 10 miles wide. But there are people who choose to wait things out in Houston and Galveston, for many foolish reasons, but not least of which because they hear that Ike is only Category 2. So why doesn't the NOAA and the media convey more information, use a different scale that takes into account storm size as well as wind speed, or at least quote the numbers together? Such as 'Hurricane Ike is a Category 2x550 storm' (550 miles across)."

Submission + - The Adobe PDF license trap

Gene A writes: "I wanted to download Adobe Reader on to my computer so I could read PDF files. I went to Adobe's web site. The Download page said, "By clicking the Download button you agree to the License Agreements and Privacy Policies for the software included." Dutifully, I went to read the license page and it said, "You can access the product license in Adobe® Portable Document Format (PDF) by ..." Obviously, the web site maintainers at Adobe have read the novel, Catch 22."

Submission + - Using ITunes Genius Isn't Smart (daniweb.com)

rsmiller510 writes: "The other day I downloaded the latest version of iTunes and discovered the much-heralded Genius feature is a not-so subtle way to sell content on iTunes. First, you have to transmit a list of the contents of your library to Apple, then they make suggestions in the iTunes store based on your content. Genius also can build playlists based on your content in your library, but not unless you transmit to Apple your information to Apple first. They could have made it a service that just checks your library or lets you share your info to get suggestions from the Apple store, but they chose to force you to send your information and that's what really bothers me."

Submission + - Chrome browser and Microsoft's website

gksmith writes: I've been using the Chrome browser for a week, with Microsoft's site as my home page. This morning I fired up Chrome and my hard disk started going crazy. If I navigated to other sites, the hard drive continued thrashing, but closing Chrome altogether instantly silenced the hard drive. If I go to www.microsoft.com using IE or Firefox, the hard drive remains idle. I've opened Chrome several times over the last few hours and hard drive thrashing is now predictable. Anyone else see this happening? Anyone know why it would?

Submission + - Robert Heinlein's Fan Mail Solution

Hugh Pickens writes: "Kevin Kelly has an interesting post about a letter he found from Robert Heinlein from Kelly's days editing the Whole Earth Catalog with Heinlein's own nerdy solution to a problem common to famous authors: how to deal with fan mail. In the days before the internet, Heinlein's solution was to create a one page FAQ answer sheet — minus the questions. Then he, or rather his wife Ginny, checked off the appropriate answer and mailed it back. Some of the entries in Heinlein's answer sheet are quite illuminating and amusing. Our personal favorite: "You say that you have enjoyed my stories for years. Why did you wait until you disliked one story before writing to me?""

Submission + - Non-Random DL #s Making Identity Theft Easier?

jazzduck writes: "My father recently was contacted by an anonymous caller who claimed that he was doing a survey on identity theft. The caller claimed to have found my father's SSN online and was calling to "notify" him and ask if he knew it was available. But the interesting part is when the caller said, "Oh, and I also have your driver's license number. It's ####-####-####... but I can't make out the last two digits on the picture, what are they?" This caught my attention because we live in Wisconsin. In Wisconsin, all but the last two digits of your Driver's License number can be calculated from your last name, first and middle initials, gender, and date of birth. The final two digits are a random or maybe sequential code that eliminates duplicates. Back in high school I reverse-engineered the algorithm for kicks, which is why my father was smart enough to know to not give out his last two digits. So was this guy legitimate? It seems to me that he was likely some kind of scammer who had calculated the first twelve digits and was trying to trick my father into revealing the two non-calculable digits. But what would he want someone's driver's license number for? Very few things use your driver's license number. More importantly, do states that use driver's license numbers like this, which can be determined from commonly available information, put their citizens at greater risk of identity theft? I know that Illinois uses a similar algorithm and I believe at least one other state does too. What does Slashdot think?"

Submission + - The CookieMonster Demands Satisfaction (fscked.org)

mikepery writes: "------ Begin Cut Here —
Note to slashdot editors: Hey guys, I was wondering if you could help me out a bit to correct for the fairly inaccurate article you featured about my HTTPS hijacking work being a Gmail-specific attack tool. I want to make sure the record is set straight, and people realize that a lot more sites are potentially affected than just Gmail, so that they can ensure they are fixed properly.
------------ End Cut Here —

I figure the slashdot readership is the best place to reach a large number of slacking admins and developers, so I want to announce that it's been 30 days since my DEFCON presentation on HTTPS cookie hijacking, and as such, it's now time to release the tool to a much wider group. Despite what was initially reported, neither the attack nor the tool are gmail-specific, and many other websites are vulnerable. So, if you maintain any sort of reasonable looking website secured by any SSL certificate (Sorry Rupert, you lose on both counts), even if it is just self-signed, you can contact me and I will provide you with a copy of the tool. Be sure to put "CookieMonster" in the subject, without a space.

I'd also like to encourage security professionals and consultants to request a copy of the tool for use in encouraging their clients to adopt SSL properly for their websites. There's no possible way for me to reach every site, but if convincing demonstrations can be given of the vulnerability on an individual basis, perhaps that will drive the issue home much more than the press alone has done. Heck, the tool might even land you a few new clients."

Submission + - Google Chrome privacy worse than you think (wordpress.com)

coderrr writes: "Google Chrome's location bar auto suggestion feature (Omnibox) is one of the biggest privacy breaches in web browser history. The feature allows Google to know almost every URL, partial URL, phrase, word, and character you type into the location bar even before you press enter. More than that, all this information can be linked with your main Google account, because Google sends your cookie along with every automatic search it performs from the location bar. A representative from Google said they plan to store about 2 percent of that data along with the IP address of the computer that typed it. The feature can be turned off, but is on by default."

Submission + - Photonovelists Start Running Into Each Other

TechnicolourSquirrel writes: In a kind of fan convention replay of Man Bites Dog, one camera-wielding photo comic creator encounters another at Fan Expo 2008 in Toronto, resulting in some amusingly self-reflexive photoblogging that may demonstrate the value of the network effect in the field of photonovels. The blogger also has this to say about convention culture: "Far more this year than last year, the gamers were segregated from the rest of the convention-goers. Nonlinear geeks are not like linear geeks. The clustering vibe is as different as between a clan of badgers and a herd of buffalo. It shouldn't really be necessary to separate them — that takes care of itself. I would have preferred it if the organisers had used their floor plan to force a little more mixing".

[Note for Eds: This is a corrected version of the story I submitted earlier, in which I believe I mistakenly wrote 'Man Bites Bog' where I intended to write 'Man Bites Dog'. This is the corrected copy — you may post it or use it as a guide to correct the original timestamped version, or just reject both as you wish. Apologise for doing it this way — it was the only way I knew to be sure the same people would see it.]

Submission + - MythBusters to Debunk Moon Conspiracies Tonight (popularmechanics.com)

mattnyc99 writes: A couple years back, we got Jamie Hyneman and Adam Savage to open up on Slashdot about so-called moon myths. Tonight, the MythBusters go all-out to finally put to rest all the conspiracy theorists who say NASA never landed on the lunar surface. From Popular Mechanics' in-depth look behind the scenes of the episode: "NASA has been incredibly open-source about the missions to the moon, about every scrap of information down to the material in the astronaut's socks," Savage says. "So you have a tremendous amount of material to choose from to make sure that your replication is entirely accurate. We had probably a greater breadth of information than we usually have to achieve the replication. But that also means that you've got to be a little bit more picky, and choose carefully so that you're not overwhelming yourself with details that aren't actually germane to the myth you're doing."
