A Mersenne prime is a prime number of the form 2P-1. There are 41 known Mersenne primes. The first few values of P which yield a Mersenne prime are 2, 3, 5, 7, 13 (the corresponding primes are 3, 7, 31, 127, 8191). A Lucas-Lehmer primality test is used to determine if 2P-1 is prime. For further information, visit Chris Caldwell's superb web page on Mersenne primes.
Finding new Mersenne primes is not likely to be of any immediate practical value. This search is primarily a recreational pursuit. However, the search for Mersenne primes has proved useful in development of new algorithms, testing computer hardware, and interesting young students in math.
It was easy, all I did was make it look like it was easy to get through one of the openings. But the trick is the big marbles don't fit through the hole.
in the trailer when they sale "A tale best forgotten." i'd like to see a real movie based on Discworld. The special effects in this look like something I would do:P
* 245392 - Installer options for where to put start menu / desktop / quick launch shortcut icons.
* 231062 - Provide Firefox MSI package.
Major improvements
* 124561 - Anonymous ftp login failure should prompt for username/password.
* 151375 - Focus outline should be drawn outside of element.
* 133165 - Focus outline should include larger descendants of inline elements.
* 65917 -:active neither hierarchical nor picky about what can be activated.
* 175893 - Make XUL 's focusable.
* 20022 -:hover state not set until mouse move.
* 276588 - Rework toolkit command-line handling. You can now open local files easily from the command-line (e.g. firefox.exe README.txt), and command-line switches should do the same thing whether Firefox is running or not.
* 95227 - Make it possible to set different default font type (serif vs sans serif) for different languages.
* 16940 - [Windows] IME is now disabled for password fields.
* 151249 - [Mac] Middle click on link does nothing on Mac OS X (should open link in new tab).
* 238854 - [GTK2] Changing GNOME2 theme doesn't apply until restarting Mozilla.
New web developer features
* 24861 - Quotes nesting (CSS "quotes" property, elements).
* 238099 - CSS at-rule for matching on site/document URL. This makes it possible to include site-specific rules in user style sheets.
* 237568 - CSS3:only-child.
* 251162 - CSS3 columns.
* 163174 - CSS3 cursors.
* 72747 - CSS3 overflow-x and overflow-y properties.
* 24676 - Support -moz-outline-radius.
* 73409 - document.open("text/plain").
* 164482 - XML Events (?)
* 251418 - Expose progress notification events through nsIXMLHttpRequest.
* 253391 - Elements with tabindex="-1" should be focusable even though not in tab order.
* 76197 - Scrollbars should look disabled when there's nowhere to scroll.
New extension developer features
* 128398 - Hidden referrer column for History. (Examples of extensions this makes possible: How'd I Get Here, advanced history visualizations.)
* 142255 - Provide a way to prioritize HTTP connections. (Examples of extensions this makes possible: prioritize current tab, prioritize pages over images, prioritize one download over another.)
* 179006 - API for managing user and UA stylesheets. (Examples of extensions this makes easier: Flashblock, per-site user stylesheet editor. This also makes it possible for user style sheet hacks, such as support for or blocking Google ads, to become simple extensions.)
* Ability for extensions to implement new command-line switches (?)
Notable bug fixes
* 217527 - Left column on Slashdot is sometimes too narrow or too wide for its contents.
* 238493 - (Re)implement widget change caching. (Fixed problems where ads in pages such as Gamespot would flicker into other parts of the page during page load.)
* 47350 - Current scroll position not retained, reloading or going back to multipart/x-mixed-replace (e.g. Bugzilla bug lists).
* 157004 - Error pages should be stored in history and show the original URL in the address bar.
* 237244 - "Try Again" on XUL error pages does not repost form data. (Now that this bug and the previous bug are fixed, I recommend enabling error pages. To enable error pages, go to about:config and set browser.xul.error_pages.enabled to true.)
* 69114 - Opening Internet Shortcuts (.url files) doesn't work (using File | Open or file protocol)
* 97283 - Mouse wheel scrolling does not work for elements such as div using overflow - auto or scroll.
* 251986 - Keyboard scrolling does not work for elements such as div using overflow - auto or scroll.
* 62384 - Text Zoom doesn't change dropdown height (without reload).
* 162081 - Wrong letter is underline
Funny about that, I usually prefer the sound of music than the sound of vinyl.

Does this mean we will have a cool new way to do one of those pictures for your wall that you change with your computer? I have been interested in them but they seem to be a waste of power.
I got some Anime in ogg once. It was the Rurouni Kenshin OVA. It was such a wonderful format and I could switch between english/jap audio and subs just by right clicking a system tray icon.
I really wish the Anime community saw it as a viable format rather than using XVid and DivX for everything. OGG is beautiful.
How could a computer possibly work out what media is sports or music videos or anime or tv shows or whatever. We need a new format like WMV (It contains XML type things in it) with XML wrapped inside that can be extracted and read that contains proper Genre and Category and such. I think WMV has this but it's not compulsury and doesn't get used often. If these formats were to take off then I could see this happening.

Ah yes my mistake. They are 250mb OGM files. Oh well it's still beautiful and should be employed as the Anime standard.
I expect once we get quantum computing in 20 or so years this will solve the video problem ;)
