unteer writes "I am a US Peace Corps volunteer currently teaching a computer technician course at a technical college in Kenya. My students have all completed the Kenyan equivalent of high school and have been accepted into a program where they give a year of nation-building non-military service in return for a technical education. My students' course load includes an introduction to computer networking, and this is where my problem lies. Do any of you know of a visual network simulator that can create an interactive network map that allows me, the instructor, to manipulate various components of a network, including the physical media, routing configuration, and which applications are being used to submit data? An example would be to have a visual of the differences between mail traffic and web traffic, and be able to show how the configuration of a wireless network might be different from a wired network. I know this may seem silly, but visuals of all this are critical to getting ideas across. It doesn't even have to be technically accurate, but rather just pictorially accurate, possibly just labeling the various components correctly. Also, it would be highly preferable if it ran on Linux, as I teach using FOSS only."

adeelarshad82 writes "Dell Streak, the Android-based 5-inch tablet (which has also been called out as a smartphone) is set to ship starting in July, both from a US carrier and direct on Dell.com for $500. Even though Dell has not disclosed the name of the carrier, some experts believe that it will be AT&T because the Streak is a 3G GSM 850/1900 device and AT&T is the only major US carrier that supports those frequency bands. According to a hands-on, Streak is a sharp-looking device with a black front and candy-apple red back that unfortunately shows fingerprints easily. On the upside, Streak's curved body is comfortable to hold. Streak runs a customized version of Android 1.6, but Android aficionados will have to get used to the unusual button layout. Its 800x480-pixel screen makes images look tight, and web pages will benefit from the horizontal resolution. The 1 GHz Qualcomm Snapdragon processor, the same as in the HTC Incredible and Sprint EVO 4G, functions snappily. There's a 5-megapixel camera on the back, a VGA camera for video calling on the front, and a MicroSD memory card slot under the back cover."

metasonix writes "While the rest of the industry has been babbling on about the iPad and imitations thereof, Qi Hardware is actually shipping a product that is completely open source and copyleft. Linux News reviews the Ben NanoNote (product page), a handheld computer apparently containing no proprietary technology. It uses a 366 MHz MIPS processor, 32MB RAM, 2 GB flash, a 320x240-pixel color display, and a Qwerty keyboard. No network is built in, though it is said to accept SD-card Wi-Fi or USB Ethernet adapters. Included is a very simple Linux OS based on the OpenWrt distro installed in Linksys routers, with Busybox GUI. It's apparently intended primarily for hardware and software hackers, not as a general-audience handheld. The price is right, though: $99."

courteaudotbiz writes "In a court battle in the province of Quebec, Canada, initiated more than two years ago, free software activists Savoir Faire Linux (translated 'Linux know-how') won the right to submit offers (Google translation; original French version) when the government takes public requests for submissions to replace its desktop operating systems and office suites. This opens the possibility in the future of replacing Microsoft Windows and Microsoft Office in favor of Linux and OpenOffice.org, or any other operating system and office productivity suite. In his judgment, the magistrate said that the government acted illegally when it discarded the proposal of Savoir Faire Linux for replacing Windows XP with a Linux distribution."

Roblimo writes "Zappa's 'Dinah-Moe Hummm' is totally about Linux, at least in spirit, while the song 'Montana,' with its talk of zirconium-encrusted tweezers and dental floss, 'is obviously about Mac users.' Not only that: In the early '70s Zappa wrote a song called 'Penguin in Bondage,' an obvious foretelling of the anti-Linux lawsuits and threats from SCO, Microsoft, and other evildoers. Zappa was also a heavy user of the Synclavier, an electronic music machine that was a precursor to today's 'studio on a computer' recording and sound editing software. According to an article on DevX, today Zappa would no doubt be using Linux and Ardour for most of his recording and composition."

Kidfork writes "On Wednesday Google's vice president of product management said that this fall Google will launch Chrome OS to compete with Microsoft Windows. More than 70 million users already use the Chrome Browser, and Google expects at least 1 million users of the OS by day one of release."

Reader awyeah notes a Financial Times report that Google is ditching the use of Windows internally. Some blogs have picked up the FT piece but so far there isn't any other independent reporting of the claim, which is based on comments from anonymous Googlers. One indication of possibly hasty reporting is the note that Google "employs more than 10,000 workers internationally," whereas it's easy enough to find official word that the total exceeds 20,000. "The directive to move to other operating systems began in earnest in January, after Google's Chinese operations were hacked, and could effectively end the use of Windows at Google. ... 'We're not doing any more Windows. It is a security effort,' said one Google employee. ... New hires are now given the option of using Apple's Mac computers or PCs running the Linux operating system. 'Linux is open source and we feel good about it,' said one employee. 'Microsoft we don't feel so good about.' ... Employees wanting to stay on Windows required clearance from 'quite senior levels,' one employee said. 'Getting a new Windows machine now requires CIO approval,' said another employee."

An anonymous reader writes "After announcing plans to go open source due to the success of the Humble Indie Bundle, developer Cryptic Sea has released the source code of 2-D platformer Gish under the GPLv2. There's a mirror on github."

With an Android armada on the horizon (or at least expected), reader androidtablet plugs this piece on ways Android could be truly tablet-friendly. Armchair engineering may be easy to knock, but I like the ideas presented here, such as aggressively using the inactive (locked) screen state to display useful information.

infoLaw passes along this excerpt from Threatpost: "Carnegie Mellon University's Computer Emergency Response Team has released a new fuzzing framework to help identify and eliminate security vulnerabilities from software products. The Basic Fuzzing Framework (BFF) is described as a simplified version of automated dumb fuzzing. It includes a Linux virtual machine that has been optimized for fuzz testing and a set of scripts to implement a software test."

ndogg writes "Security experts found that the iPhone 3GS has very little security, even with a PIN set up. They plugged one into Ubuntu 10.04, and it was automounted with almost all of the iPhone's data exposed. This has been reported to Apple, but the company seems to be having difficulty reproducing the problem."

omlx writes "KDE SC 4.5 is in feature freeze right now. Therefore, I decided to share some early screenshots with you. In general there are no major changes; it's all about polishing and fixing bugs. There are a lot of under-the-hood changes in libs, which as end users we cannot see. KDE SC will be released in August 2010." Note: you can also try out a beta of the release now, if you'd like.

tc6669 writes "Tom's Hardware just posted an interesting review of Ubuntu 10.04 LTS. It includes an expanded set of OS benchmarks that they also performed on the previous LTS release (8.04), to see just how much the mainstream Linux distro has progressed in two years."

Julie188 writes "Details on this are admittedly sketchy, but both Red Hat and Xen.org have gone on record promising that some kind of support for the Xen hypervisor is forthcoming for Fedora users. As we know, on Monday, Fedora 13 was released, chock full of features to appeal to business users. One of the ballyhooed improvements to 13 is virtualization — meaning KVM and only KVM — for Red Hat. Xen was dropped from Fedora a few releases ago and it hasn't come back in 13, except that 13 still supports Xen guests. Meanwhile, 'work is underway in Xen.org to add platform support to Fedora 13 post-release,' promises Xen.org's Ian Pratt."

It includes major features such as automatic print driver installation, automatic language pack installation, redesigned user account tool, color management to calibrate monitors and scanners, experimental 3-D support for NVIDIA video cards, and more."

Several readers made sure we are aware that Slackware 13.1 release is out. Here's the list of mirrors. "Slackware 13.1 brings many updates and enhancements, among which you'll find two of the most advanced desktop environments available today: Xfce 4.6.1, a fast and lightweight but visually appealing and easy-to-use desktop environment, and KDE 4.4.3, a recent stable release of the new 4.4.x series of the award-winning KDE desktop environment."

whisper_jeff writes "Engadget has an interesting article up discussing whether or not Android is fragmenting. While the article discusses the concept that it may be more about handsets becoming obsolete at a dramatic pace rather than the OS fragmenting, it also begins by noting that there are currently five different versions of Android on the market, which implies there is a notable degree of fragmentation. Regardless of it being fragmentation or handsets becoming obsolete to new feature sets in a terribly short period of time, I believe this development cycle could turn casual consumers away and hurt Android's chances for long-term mainstream success."

Malvineous writes "I have two devices, from two different companies (who shall remain nameless, but both are very large and well-known) which run Linux-based firmware. The companies release all their source code to comply with the GPL, but neither includes a build environment or firmware utilities with the code. This means that if you want to alter the free software on the device, you can't — there is no way to build a firmware image or install it on the devices in question, effectively rendering the source code useless. I have approached the companies directly and while one of them acknowledges that it is not fully GPL-compliant, due to other license restrictions it cannot make the build environment public, and the company does not have the resources to rewrite it. I have approached the FSF but its limited resources are tied up pursuing more blatant violations (where no code at all is being released.) Meanwhile I am stuck with two devices that only work with Internet Explorer, and although I have the skills to rewrite each web interface, I have no way of getting my code running on the devices themselves. Have these companies found a convenient way to use GPL code, whilst preventing their customers from doing the same?"

Kilrah_il writes "After HP bought Palm a few weeks ago, many rumors emerged regarding the new parent company's plans to further expand the scope of devices running WebOS. Now it appears that at least one of the rumors is true: The Slate will be running WebOS.
