In quantum physics, one of the calculations you might want to do is figure out how two or more particles may interact. This can become rather complicated and confusing once you get to more than two particles interacting, however. Also, depending on the interaction, there may be the creation and annihilation of virtual particles as part of the interaction. How can you keep all of this straight and figure out what could be happening?

Despite several attempts, the Linux Foundation's James Bottomley has not managed to get Microsoft to sign the mini bootloader for starting Linux on systems with UEFI Secure Boot. In a blog post, the Linux Foundation Technical Advisory Board (TAB) member says that he successfully managed to use a Linux system for various preparatory bootloader signing tasks, although Microsoft stipulates that a specific Windows platform must be used. However, Bottomley said that to upload the CAB file containing the bootloader, he had to use a virtual machine with Windows 7 because this step requires Silverlight, and the open source Moonlight implementation of Silverlight didn't work.

This tutorial describes how you can install Apache2 with mod_fcgid and PHP5 on OpenSUSE 12.2. mod_fcgid is a compatible alternative to the older mod_fastcgi. It lets you execute PHP scripts with the permissions of their owners instead of the Apache user.

Unix as a whole predates Linux by many years, and even the rather younger BSD variant was well into its teens by the time Linus released his first kernel. BSD networking defined and enabled the Internet. This illustrious history notwithstanding, BSD has long since ceded the spotlight to Linux in most settings. As Linux has come to dominate the free software development world, the result has been some occasional pain for other operating system distributions. Now, as a recent discussion on an OpenBSD mailing list shows, BSD developers are feeling that pain in a heightened manner. This situation has some serious implications.

Linux Mint’s Release Candidate turn around was very fast, with the full version of 14 now available

A new phone OS based on the work Nokia abandoned on its Linux-based mobile OS has been unveiled in Helsinki. Jolla is a start-up run by former Nokia staffers devised to build on the old MeeGo project, which is now called Mer. The Sailfish OS is Mer with proprietary elements: a new user interface. Jolla has an agreement with Chinese retailer D.Phone, China's equivalent to Carphone Warehouse. The start-up inherited no IP whatsoever from Nokia, and the UI is completely new. The backing comes from China which sees a lot of potential in an Android alternative.

In around 15 minutes, the time it takes to install Ubuntu Server Edition, you can have a LAMP (Linux, Apache, MySQL and PHP) server up and ready to go. This feature, exclusive to Ubuntu Server Edition, is available at the time of installation.The LAMP option means you don’t have to install and integrate each of the four separate LAMP components, a process which can take hours and requires someone who is skilled in the installation and configuration of the individual applications.

Various improvements to the major open-source Linux graphics drivers will be landing with the Linux 3.8 kernel in the months ahead...

That’s less than 10 days after the first Release Candidate was announced. What type of testing does this thing get? By the way, that’s normal for Linux Mint distribution, but again, how well is this distribution tested before it’s released to the public?

A previously unknown rootkit is infecting Linux web servers and injecting malicious code into web pages served by infected servers. The rootkit was discovered by a user of security mailing list Full Disclosure, who has posted his observations, including the suspicious kernel module, to the mailing list. The malware adds an iframe to every web page served by the infected system via the nginx proxy – including error pages.

Another interesting session from this month's LLVM Developers' Meeting in San Jose was about how Google manages to collect and utilize Clang diagnostics internally for software they develop at the company...

Standard releases aren't terribly different from the bi-annual LTS products, though they tend to be slightly less conservative in code offerings. The Ubuntu development community lets off the brakes a little and sticks some shiny back in.

Ubuntu 12.10 is no exception, so make no mistake—there's some shiny goodness in this release. We'll get into what makes this a decent desktop and even more decent server release. But there's a little tarnish mixed in, too, and that makes Ubuntu 12.10 less special than previous editions.

One of the biggest talking points in the run-up to the release of Windows 8 has been the feature that will supposedly lock down the operating system so that it cannot be infected by malware at boot-time.

While this week marks one year since the Doom 3 (id Tech 4) game engine was open-sourced under the GPL, there still isn't too much adoption by open-source game developers. The few forks of the id Tech 4 code-base also aren't seeing frequent activity...

Says explosion of smartphone patent litigation is "natural and reasonable." David Kappos, the head of the United States Patent and Trademark Office, offered a strong defense of software patents in a Tuesday address at the Center for American Progress. Kappos touted several provisions of the America Invents Act (AIA), which he argued would allow the patent office to weed out low-quality software and business method patents. Addressing those who claim the patent system is broken, Kappos said, "Give it a rest already. Give the AIA a chance to work. Give it a chance to even get started."

At the gates of Microsoft, there are numerous competing Windows versions now almost falling over each other as they strive for marketshare.

In my test of the Fedora 18 Alpha release, I was left thinking the "connect to server" feature in the Nautilus file manager disappeared in versions 3.5.x and 3.6.x of the GNOME desktop environment. Thanks to readers, I learned that "connect to server" has moved to a separate application that you call from the shell with the not-so-friendly name "Nautilus-connect-server."

ARM's AArch64 back-end for LLVM to handle the 64-bit ARMv8 architecture is working, but there's still more work ahead of the hardware's general availability in about one year's time...
