Comment Re:Cheating on my first love - Firefox (Score 1) 383

GIMP is C/C++ code loaded in a compiled state. The majority of Firefox's functionality is in the form of JavaScript that has to be compiled at some point.

GIMP is compiled and then run, Firefox is run (and of course the core is compiled) but then it has to unzip a bunch of files and read a bunch of XML, JavaScript and other resource files, turn them into something usable in memory and then do its thing.

FireFox is FAR more flexible than GIMP, but that comes at a cost of speed.

You can actually speed FireFox up with a custom build (an option to configure for FF actually) or by uncompressing all the chrome for firefox before hand. In theory it shouldn't matter as FF caches it, but it does make a difference.

The main thing is that they aren't shooting for the same targets. Chrome is trying to be as fast as possible so Google's webapps run fast and feel more like native apps. FireFox on the other hand is trying to be far more flexible.

What is with people whining about AdBlock all the time? OH NOES TEH ADZ@!1!One. Is it really that big a deal? Thanks to my Slashdot obsession and excellent karma, I have the option to disable ads on Slashdot natively, but I don't even use the option. Why do people care so much about little images trying to sell things?

Underground Lab To Probe Ratio of Matter To Antimatter 82

Wired reports on the Enriched Xenon Observatory 200, a particle detector scientists hope will answer the question of why there is significantly more matter than antimatter in the universe. Quoting: "The new detector will try to fill in the picture, determining basic features of [neutrinos], like their mass and whether or not they, unlike almost all other particles, are their own antiparticles. That quirk is why some scientists believe neutrinos could be the mechanism for the creation of our matter-filled universe. Almost all other particles have an antiparticle twin that, if it comes into contact with the particle, immediately annihilates it. But if neutrinos are their own antiparticles they could conceivably be knocked onto matter's 'team,' thereby causing the cascading win for matter over antimatter that we know occurred. As the Indian theoretical physicist G. Rajasekaran put it in a speech [PDF] earlier this year, neutrinos that are their own antiparticles would explain 'how, after [the] annihilation of most of the particles with antiparticles, a finite but small residue of particles was left to make up the present Universe.'"
Data Storage

Ext4 Advances As Interim Step To Btrfs 510's Kernel Log has a look at the ext4 filesystem as Linus Torvalds has integrated a large collection of patches for it into the kernel main branch. "This signals that with the next kernel version 2.6.28, the successor to ext3 will finally leave behind its 'hot' development phase." The article notes that ext4 developer Theodore Ts'o (tytso) is in favor of ultimately moving Linux to a modern, "next-generation" file system. His preferred choice is btrfs, and Heise notes an email Ts'o sent to the Linux Kernel Mailing List a week back positioning ext4 as a bridge to btrfs.

First Secure Quantum Crypto Network Up and Running 102

John Lam was one of many readers to send in news that on Thursday, "at a conference in Vienna, Austria, as reported by the BBC, a European Community science working group built a quantum backbone using 200-km of standard commercial optical fiber running among seven sites and successfully demonstrated the first secure quantum cryptographic key distribution network. In addition, each of the seven links used a different kind of quantum encryption, demonstrating interoperability between the technologies. To paraphrase, the project focused on the trusted repeater paradigm and developed an architecture allowing seamless integration of heterogeneous quantum-key distribution-link devices in a unified framework. Network node-modules managing all classical communication tasks provide the underlying quantum devices with authentic classical channels. The node-module architecture uses a layered model to provision network-wide, end-to-end, provably secure key distribution."

Linux 2.6.27 Out 452 writes "Linux 2.6.27 has been released. It adds a new filesystem (UBIFS) for 'pure' flash-based storage, the page-cache is now lockless, much improved Direct I/O scalability and performance, delayed allocation support for ext4, multiqueue networking, data integrity support in the block layer, a function tracer, a mmio tracer, sysprof support, improved webcam support, support for the Intel wifi 5000 series and RTL8187B network cards, a new ath9k driver for the Atheros AR5008 and AR9001 chipsets, more new drivers, and many other improvements and fixes. Full list of changes can be found here."

Messenger Sends First Full Fly-By Image of Mercury 55

An anonymous reader writes with this snippet from Gizmodo: "NASA's Messenger (MErcury Surface, Space ENvironment, GEochemistry and Ranging spacecraft) has flown by just 125 miles over the surface of Mercury, the closest planet to the Sun and the smallest in the Solar System. This is the first time in history that the whole planet is going to be photographed in its entirety by an Earthling probe, with amazing resolution and ultra-crisp detail." The picture at the top of the linked story is fantastic, too.

Submission + - The physics arXiv blog (

ultracool writes: If you are interested in the latest happenings in physcis, I would recommend checking out the the physics arXiv blog. It summarizes various general interest articles submitted to the arXiv for a broad (but physics-inclined) audience. From the about page:

'If ya'll been a-wundrin how physics is born, let me tell ya. It's just like your mammy and pappy told. The great white stork posts physics on the arXiv and leaves it a-cryin and a-hollerin until somebody starts a-lovin and a-nurturin it. If they do it just right-just right, mind-it'll one day grow up into a full force o' nature.

Ya'll can think of this lil ol blog as a kinda birth announcement where ya can see the little uns as soon as they arrive. Then ya'll can start a-cooin and a-cuddlin over the pertee ones.'


Submission + - Why Did Blu-Ray Win?

AndresCP writes: Now that Blu-Ray has definitively won our most recent format war, it's time to reflect on the past. Specifically, why was Blu-Ray able to pull ahead with the major companies and (to a limited extent thus far) with consumers? As a Slashdot member since before the format war, I feel that the opinion here was that HD DVD would probably win in spite of Blu-Ray's technical superiority. That was my thought too, given Sony's disastrous track record with proprietary formats and the idea of consumer inertia influencing the purchase of familiar sounding "HD DVD" over the scarier "Blu-Ray." So, what went right for Sony and wrong for Toshiba?

Feed Science Daily: Turning 'Funky' Quantum Mysteries Into Computing Reality (

The strange world of quantum mechanics can provide a way to surpass limits in speed, efficiency and accuracy of computing, communications and measurement, according to new research. Quantum mechanics is the set of physical theories that explain the behavior of matter and energy at the scale of atoms and subatomic particles. It includes a number of strange properties that differ significantly from the way things work at sizes that people can observe directly, which are governed by classical physics.


DOE Awards 265 Million Processor-Hours To Science Projects 59

Weather Storm writes "DOE's Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program supports computationally intensive, large-scale research projects at a governmental level. They recently awarded 265 million processor-hours to 55 scientific projects, the largest amount of supercomputing resource awards donated in the DOE's history and three times that of last year's award. The winners were chosen based on their potential breakthroughs in the areas of science and engineering research, and the suitability of the project for using supercomputers. This year's INCITE applications ranged from developing nanomaterials to advancing the nation's basic understanding of physics and chemistry, and from designing quieter cars to improving commercial aircraft design. The next round of the INCITE competition will be announced this summer. Expansion of the DOE Office of Science's computational capabilities should approximately quadruple the 2009 INCITE award allocations to close to a billion processor hours."
