AdmiralXyz writes "I'm a university student, and I like to take notes on my (non-tablet) computer whenever possible, so it's easier to sort, categorize, and search through them later. Trouble is, I'm going into higher and higher math classes, and typing "f_X(x) = integral(-infinity, infinity, f(x,y) dy)" just isn't cutting it anymore: I need a way to get real-looking equations into my notes. I'm not particular about the details, the only requirement is that I need to keep up with the lecture, so it has to be fast, fast, fast. Straight LaTeX is way too slow, and Microsoft's Equation Editor isn't even worth mentioning. The platform is not a concern (I'm on a MacBook Pro and can run either Windows or Ubuntu in a virtual box if need be), but the less of a hit to battery life, the better. I've looked at several dedicated equation editing programs, but none of them, or their reviews, make any mention of speed. I've even thought about investing in a low-end Wacom tablet (does anyone know if there are ultra-cheap graphics tablets designed for non-artists?), but I figured I'd see if anyone at Slashdot has a better solution."

palegray.net writes "The latest version of Ubuntu 9.10 (Karmic Koala) has been released. Offering numerous enhancements for both desktop and server environments, this release includes notable features like Ubuntu Enterprise Cloud images, the Ubuntu One 'personal cloud,' and Linux kernel version 2.6.31. Please be sure to use a release mirror close to your geographic location to help reduce the stress on Ubuntu's primary servers; using BitTorrent for downloads can help alleviate the load even more. If your organization has adequate network and server resources, please consider hosting a mirror as well."

Barence writes to tell us that Canonical plans on limiting the number of "free Ubuntu CDs" that people can mooch from the company. The growing popularity of Ubuntu has seen a dramatic increase in the number of CDs being shipped via the free "ShipIt" scheme. The only people able to take advantage of this program now will be the usual community teams, contributors, and first-time Ubuntu users. "'While these CDs are often referred to as 'free CDs,' they are of course not free of cost to Canonical. We want to continue this programme, but Ubuntu’s growth means that some changes are necessary. Therefore we are adjusting how we handle CD requests to try to find the right balance between availability of CDs and the continued viability of the ShipIt program,' [Canonical's chief operating officer Jane Silber] adds. Extra CD copies of Ubuntu will still be available for purchase through the Canonical store, although they need to be bought in bulk. Five copies of the open-source operating system will cost £5 exc VAT and shipping."

oranghutan writes "Computerworld is reporting Canonical has made available the Release Candidate of its latest Linux-based operating system, Ubuntu 9.10, on the same day Microsoft launched the long-awaited Windows 7. 'The upcoming Canonical release, which is code-named Karmic Koala, is the latest version of the popular flavor of the Linux OS. The development release on Thursday pushed the OS one step closer to final release, which is due on Oct. 29, according to the company's release schedule Web page. An image of the OS is available for download on Ubuntu's Web site. Test versions of Karmic Koala RC available for download include the server, desktop and netbook versions.'"

An anonymous reader writes "It looks like IBM isn't much of a friend of Microsoft's anymore. Today IBM announced an extension of its Microsoft-Free PC effort together with Canonical Ubuntu Linux. This is the same thing that was announced a few weeks back for Africa (a program that began a year ago), and now it's available in the US. The big push is that IBM claims it will cost up to $2,000 for a business to move to Windows 7. They argue that moving to Linux is cheaper."

stoolpigeon writes "Google's mobile OS Android has received plenty of press. As with a lot of Google products, there was much anticipation before any devices were even available. Now a number of phones are available, with many more coming out world-wide in the near future. Part of the lure of Android is the openness of the platform and the freely available tools for development. The SDK and accompanying Eclipse plug-in give the would be creator of the next great Android application everything they need to make their idea reality. The bar to entry in the official Google Android Marketplace is very low and it doesn't seem to be much of a stretch to predict that the number of developers working on Android is only going to grow. As with any hot technology the number of books will grow as well and O'Reilly's Android Application Development has jumped into the fray, promising to help budding Android developers what they need to get started."

s31523 writes "I love my current laptop, but unfortunately on my last trip the primary LCD went bonkers. It's an older Gateway (2 GB RAM Intel Pentium M 2.0 GHz, ATI M7). There are a handful of features I love about it: [1] Hot-swappable drive bay, with several components that can go in: CD/DVD R/W, extra battery, floppy drive, extra hard drive, memory card reader, etc. The extra battery option is especially appreciated — I can go 4-5 hours on battery power. [2] Docking station / port replicator: I like having my home setup with keyboard, network, and dual screens (a necessity). [3] It runs Linux. OK, I'm a wus, I actually have GRUB command three different OS's: Windows 98 (I have really old embedded software compilers that only run on 98, and yes I have tried every trick in the book to make them run on Linux), Windows XP Pro, and Ubuntu. I'm trying to find a replacement setup that offers the same flexibility and a little better performance. I am open to change as well. So, I ask Slashdot: What is your pick for best developer's laptop under $1,200, considering the features above?"

An anonymous reader writes "Phoronix has brought benchmarks comparing the FreeBSD 8.0-RC and Ubuntu 9.10 Alpha 6 operating systems. FreeBSD rather ends up taking a wallop to Ubuntu Linux, but there are a few areas where FreeBSD 8 ran well. They also posted benchmarks comparing this near-final FreeBSD 8.0 build to that of FreeBSD 7.2 to show performance improvements there but with a few regressions."

darthcamaro writes "No surprise but Ubuntu's Mark Shuttleworth has come out swinging in favor of the Linux desktop. Speaking at Linuxcon yesterday he detailed the things that he thinks Linux requires in order to win the desktop wars. Those include: co-ordinated software releases, better quality and design, some user experience testing and oh yeah, a dose of 'shut the f*** up' too. During his keynote, he extended an invitation to any open source application to submit their software for testing by user-experience experts. The sessions would be recorded for posterity, and the developer would not be able to interact with the user. "'If the developer is in the room, they have to say nothing. It's the shut the f*** up protocol,' Shuttleworth said. 'You sit and watch someone struggle with the software that you've so lovingly produced.'"

An anonymous reader writes "Most people use MS filesystems on Disk-On-Keys, and portable hard drives, as these are readable from most machines. But this way you lose the files' permission information, which many times is very inconvenient (you must agree that having Ubuntu asking you whether to execute or display every text file or image you open from a DOK is annoying). Using 'regular' Linux filesystems like ext keeps the permissions, but may require using the superuser when switching machines (as the UIDs are different). So do any of you have a creative solution for this problem?"

DigDuality writes "Dieter@be over at Arch Linux forums, a release engineer for Arch Linux, got inspired by this post. The idea? To create a browser based on the Unix philosophy: 'Write programs that do one thing and do it well, programs that work well together, programs to handle text streams because that is a universal interface,' among other points. The result? A fast, low-resource browser named Uzbl, based on WebKit, which passes the Acid3 Test with a perfect score. The browser is controlled (by default) by vim-like keybindings, not too dissimilar to vimperator for Firefox. Things like URL changing, loading/saving of bookmarks, saving history, and downloads are handled through external scripts that you write (though the Uzbl software does come with some nice scripts for you to use). It fits great in a tiling window manager and plays extremely well with dmenu. The learning curve is a bit steep, but once you get used to it, it's smooth sailing. Not bad for alpha software. Though built for Arch, it has been reported to work on Ubuntu."

BeckySharp writes "With the nearly simultaneous release of Apple's Mac OS X 10.6 'Snow Leopard' (available right now) and Microsoft's Windows 7 (available Oct. 22), you get the inevitable debate: Which is the better operating system, Windows 7 or Snow Leopard? To help determine that, Computerworld's Preston Gralla put both operating systems through their paces, selected categories for a head-to-head competition, and then chose a winner in each category." Relatedly, Phoronix has posted Snow Leopard vs. Ubuntu 9.10 benchmarks. They ran tests from ray tracing to 3D gaming to compilation. Their tests show Ubuntu 9.10 winning a number of the tests, but there are some slowdowns in performance and still multiple wins in favor of Snow Leopard, so the end result is mixed.

Ganty writes "I recently purchased a Lenovo W500 notebook, and after 'downgrading' to XP and creating a dual partition, I found that I had a battery life of nearly three hours using the long-life battery, at this point I was a happy camper because it means that I can watch a DVD during a flight. I then tried various Linux distributions and found the battery life under FOS to be very disappointing, with an average of 45 minutes before a warning message. After settling on Ubuntu I then spent three days trying various hardware tweaks but I only managed to increase the battery life to one and a half hours. Unwanted services have been disabled, laptop mode has been enabled, the dual core CPU reduces speed when idle and the hard drive spins down when not needed. Obviously Apple with their X86 hardware and BSD based OS have got it right because the MacBooks last for hours, and a stock install of MS Windows XP gives me three hours of life. Why is battery life on notebooks so poor when using Linux? Some have suggested disabling various hardware items such as bluetooth and running the screen at half brightness but XP doesn't require me to do this and still gives a reasonable battery life."

Ant writes "The Linux Foundation's report (PDF) on who writes Linux — "... Linux isn't written by lonely nerds hiding out in their parents' basements. It's written by people working for major companies — many of them businesses that you probably don't associate with Linux. To be exact, while 18.2% of Linux is written by people who aren't working for a company, and 7.6% is created by programmers who don't give a company affiliation, everything else is written by someone who's getting paid to create Linux. From top to bottom, of the companies that have contributed more than 1% of the current Linux kernel, the list looks like this: ..."

wonkavader sends us this quote from an article in PCWorld: "In an effort to expand its Linux offerings, Dell is researching new netbook-type devices and will soon offer netbook Linux OS upgrades, a company official said on Wednesday. The company is researching the possibility of offering new Linux-based mobile devices called smartbooks, said Todd Finch, senior product marketing manager for Linux clients, at the OpenSourceWorld conference in San Francisco. The company will also upgrade its Ubuntu Linux OS for netbooks to the latest version in the next few weeks ... Smartbooks with Arm chips have inherent advantages over x86 chips like Atom, such as lower power consumption and longer battery life, according to Finch. The chips are also becoming more powerful, as indicated by the growing number of applications on smartphones, he said. 'I think it's natural and reasonable for us to begin looking at them as they begin scaling their processors up.'"

jonniee writes with a link to Dr. Dobb's Journal's look at a rather cool living-room-suitable media-centric computer from Neuros (presented as being suitable mostly for developers and serious hobbyists for now), excerpting: "The Neuros LINK is essentially a quiet x86 PC running Ubuntu Linux with an ATI graphics card delivering video via VGA, DVI, and HDMI output. ... What makes the LINK such a compelling platform for these folks and Linux/open source developers in general is the recognition that a real business entity is stepping forward to spend the money necessary to market and commercialize what tech enthusiasts have been doing for years."

sukotto writes "Ubuntu recently released an unannounced and experimental 'multisearch' extension to Firefox alpha 3, apparently in an effort to improve the default behavior of new tabs and of search. In a response to one of the initial bug reports the maintainers mentioned that the extension's other purposes were 'collecting the usage data' and 'generating revenue.' Since this extension installs by itself and offers no warning about potential privacy violations, quite a few people (myself included) feel pretty unhappy. The only way to opt out is to disable the extension manually via Tools > Add-ons." Most posters to this Ubuntu forum thread are not happy about multisearch.

Adam Wrzeski notes a piece up at Create Digital Music by musician Kim Cascone (artist's bio) on switching from Apple to Linux for audio production: "The [Apple] computer functioned as both sound design studio and stage instrument. I worked this way for ten years, faithfully following the upgrade path set forth by Apple and the various developers of the software I used. Continually upgrading required a substantial financial commitment on my part. ... I loaded up my Dell with a selection of Linux audio applications and brought it with me on tour as an emergency backup to my tottering PowerBook. The Mini 9 could play back four tracks of 24-bit/96 kHz audio with effects — not bad for a netbook. The solution to my financial constraint became clear, and I bought a refurbished Dell Studio 15, installed Ubuntu on it, and set it up for sound production and business administration. The total cost was around $600 for the laptop plus a donation to a software developer — a far cry from the $3000 price tag and weeks of my time it would have cost me to stay locked-in to Apple. After a couple of months of solid use, I have had no problems with my laptop or Ubuntu. Both have performed flawlessly, remaining stable and reliable."

djcb writes "After only 2 years since the previous version, now emacs 23 (.1) is available. It brings many new features, of which the support for anti-aliased fonts on X may be the most visible. Also, there is support for starting emacs in the background, so you can pop up new emacs windows in the blink of an eye. There are many other bigger and smaller improvements, including support for D-Bus, Xembed, and viewing PDFs inside emacs. And not to forget, M-x butterfly. You can get emacs 23 from ftp.gnu.org/gnu/emacs/ or one of its mirrors; alternatively, there are binary packages available, for example from Ubuntu PPA."
