"前些日子我花了一些時間研究如何將Google Earth 打包成RPM. 已經有一支叫做 make-google-package 的程式可以在網路上找到,但是它只能建立debian的安裝包. 然而, it was a good start to get me going to create a Google Earth (GE) rpm. Although I met quite some obstacles, which is not to uncommon in package building, I was still able to come up with a procedure a get GE packaged. The biggest problem I encountered were incorrect library dependencies, for which I opened issue 702 in the Google Earth issue tracker. Anyway to make a long story short: the rpm installs Google Earth system wide, corrects file permissions, for openSUSE_11.2 it takes care that the font is rendered correctly, the rpm takes care that Google Earth integrates nicely with the rest of the openSUSE system."
"We are proud to announce the availability of the OBS 1.7.2 release.
The new version comes with a number of bug fixes, but also with some new features back ported from master branch. The new functionality allows to use existing LDAP servers for authentication. The new instances can be setup more easily now via the admin web interface, esp the OBS Appliance."
"I’m a sucker for a cool space wallpaper, and judging by the images I find online, so are many of you. Creating a cool space scene can be done in a few minutes once you’ve got the basic method down, and Gimp provides several ways to go about adding random elements to keep things interesting. In this guide we’ll cover a 10 minute method to creating a galactic landscape that may not win you any awards but will certainly add some depth to your desktop."
"Want to take full keyboard control of Firefox? Tired of having to mouse around the Web? Firefox has a good set of shortcuts by default, but if you want to go completely keyboard-driven, take a look at Vim-inspired extension Vimperator."
"Even after decades of using Unix on thousands of systems, I find that it's still fun to discover various convolutions of sed and awk commands to perform command line wizardry. There's a lot more to each of these tools than those uses I make of these commands on a routine basis. Let's take a look at some one-liners you might not yet have tried."
"You don't need a PhD in computer science and years of experience to hack the kernel. Sure, they help, but the nature of Linux development means that it's open to all by default. All you have to do is get stuck in. You use the Linux kernel in whatever shape or form every day; wouldn't you feel just the tiniest swell of pride if you'd helped work on it, no matter in how small a way?
We asked prolific kernel hacker (and Linux Format reader!) Greg Kroah-Hartman to tell us what it takes for newbies to patch the Linux kernel - here's what he had to say..."
"One of the classic problems in designing storage solutions is that we don’t know what kind of IO performance applications need. We may have some empirical knowledge, “switching to SSD’s improved by wall clock time by 25%,” or, “adding an extra drive improved my application performance by 11%.” While this information is helpful to some degree what is missing is the understanding of why performance improved and by extension, what are the driving mechanisms behind the performance improvement. Perhaps equally important for the application developers is that understanding the driving forces of IO performance for your application can be used to improve the IO performance, if needed."
"FrostWire is a gnutella client written in Java. It supports a number of advanced features like ultrapeers (like FastTrack's supernodes), automatic download retries, freeloader punishment, etc."
"Miro is a free application that turns your computer into an internet TV video player. It's a free, open source Internet TV and video player that can automatically download videos from RSS-based channels. Features a built-in BitTorrent client."
Projects Corner
The corner for introducing activities of sub project *inside* openSUSE.
"There are multiple options to set up a slide show screen saver that shows the pictures of your choosing when the screen saver kicks in. The following shows the various options and works with the gnome-screensaver.
Easy does it
The most direct way to get a slide show screen saver going is to place your pictures in the $HOME/Pictures directory, then start the GNOME screen saver settings dialog by using gnome-screensaver-preferences from the command line or by selecting the Screensaver icon in the Control Center (gnome-control-center). In the screen saver settings dialog select “Pictures folder” and click “Close”."
"Monday I released Tomboy 1.1.4. Last month's 1.1.2 release was actually the first to feature automatic note synchronization (herein referred to as 'autosync'), but in 1.1.4 the feature is less annoying and you can actually turn it on in the Preferences UI. Here's the only possible autosync screenshot: ..."
"我想這是一個好主義,試圖的吸引你 – the fine openSUSE community – 在討論中關於 "Us" 這個社群. 我們似乎被慣壞了有一個社群經理,人們似乎讓他做他的工作或是期望更糟的去做. 現在,我們沒有任何更多的立場,我們需要回到基本問題和開始捲起我們的袖子. 我們已經開 始,但我們有很多事要做. 因此,這是第一次在我不知道有多少關於這個問題"
"New installs will at some point bring in a multitude of additional 個套件 as well as Updates. It seems to perplex some users, which may be understandable if they have a poor internet connection. With no shortage of space and a hight speed line, I tend to just go with the flow - mostly."
"I just tagged and uploaded a tarball for Plasmate 0.1-alpha2. Plasmate is our Plasma add-on creation tool and we're aiming for a summer release. Improvements since the alpha 1 release last month include not only a large number of bug fixes (thanks to everyone who tried it out and reported issues they came across!) but also some great new features, of which probably the most cool one is the online integration which allows you to grab a Plasmoid via GetHotNewStuff and instantly start working on it as well as upload your own creations using your opendestop.org account."
"Today we have released the absolute latest version of Qt for all those cutting edge folks that want to try out the newest stuff – The Qt 4.7 Tech Preview.
The 4.7.0 TP is the first step of the 4.7 release cycle, and our goal is to showcase our newest technology (such as Qt Quick) and solicit feedback so that we may improve it before locking down our APIs down for the beta. Although the quality isn’t at production level quite yet, it should be good enough for demonstrating the new features we have in mind for 4.7 final. The final 4.7.0 release is scheduled for around mid 2010, pending feedback on the new features/designs, and the overall product quality."
"As of today, people can buy t-shirts, hats, coffee mugs, stickers and other items that display the unique culture of Linux from the Linux.com Merchandise Store. This allows us all to support The Linux Foundation activities while letting our Linux geek flags fly.
The designs you see on the items today are limited to the creativity of a select few who helped us get the Linux.com Merchandise Store launched. But we know that the best ideas come from the community, not one company or organization, just like in the Linux developer community.
So, we’re inviting you to submit your design to appear on a t-shirt in the Linux.com Merchandise Store"
"Linus Torvalds has released the first RC of Linux 2.6.34 and completed the integration of the next version of the kernel's most important changes. Improvements include graphics drivers for recent Radeon GPUs and for the graphics cores of some Intel processors that are only expected to be released early next year. Another new addition is the LogFS file system."
"As strange as it might sound, there are times when I wish for the old days of the Internet circa the early 1990's. The days of Mosaic and Lynx, where there was no Flash, no Javascript and no Java. A simpler time where protecting your privacy and security wasn't as essential as it is today.
Time travel isn't an option for securing my browser. But Firefox gives me it all and then some. The number-two browser (with 32 percent market share), Firefox is a cross platform, standards based, open source browser. It is feature rich and has supernumerary add-ons to extend its functionality. In the spirit of Open Source, its community maintains a focus on security and has a strong record of swiftly patching known vulnerabilities, faster in some cases than most others in the market."
"In an age when Linux has become a powerful platform for development work, graphics processing and video production, it’s a welcome relief to see a mid-range system built for people who may or may not have experience with Linux. The HP Elite 7000 Microtower is quite capable: it has an Intel i7 860 2.8GHz quad-core processor with an 8MB L2 cache and an ATI Radeon HD 4550 graphics card built for Blu-ray movie playback. Meanwhile, with just 3GB of RAM, an 160GB SATA hard disk and little design flare, the Elite 7000 is not exactly a performance rig. The saving grace: the system can come equipped with Novel SUSE Linux Enterprise Desktop 11 and is extremely easy to upgrade."
"Text-to-Speech Software for Linux: If you've been using Mac OS X or Windows Vista before, you may be a bit disappointed to learn that there's no speech synthesizer or text-to-speech (TTS) application that is installed by default on your Linux distribution. For those of you who don't know what a speech synthesizer is, it's simply a computer program that converts normal language text into speech. Text-to-speech software can be of great help particularly for people who are visually impaired and those who are mute."
"Everyone who uses the internet knows that Google is the answer to every question. Google is a powerful search engine, and also a tool. Being such a good tool, almost like everything else on the internet today, Google’s capabilities are unfortunately being misused. To keep up to date, typically a security researcher refers to Google. This helps him learn more about new hacking trends, tools, and previous hacking incidents. Unfortunately, unless you are a hacker yourself, you cannot imagine what a hacker can be up to, since a typical security researcher can be quite naive and innocent, when compared to a real hacker. Therefore by searching and learning more on previous incidents, one can increase his knowledge and will perform better at securing websites and web applications."
