7 of the Best Free Linux Calculators 289

An anonymous reader writes "One of the basic utilities supplied with any operating system is a desktop calculator. These are often simple utilities that are perfectly adequate for basic use. They typically include trigonometric functions, logarithms, factorials, parentheses and a memory function. However, the calculators featured in this article are significantly more sophisticated with the ability to process difficult mathematical functions, to plot graphs in 2D and 3D, and much more. Occasionally, the calculator tool provided with an operating system did not engender any confidence. The classic example being the calculator shipped with Windows 3.1 which could not even reliably subtract two numbers. Rest assured, the calculators listed below are of precision quality."

Video Review of Hivision's $100 ARM-Based Android Laptop 220

Charbax writes "The Android laptops are coming. Thanks to cheap ARM-powered laptops made in China, and the latest, most optimized Android software, we can soon buy usable $100 laptops in all the supermarkets. In this video, I test the web browsing speed on the new Rockchip rk2808 ARM9-based PWS700CA laptop by Shenzhen-based Hivision Co Ltd. Web browsing on AJAX-heavy websites is surprisingly snappy, and could only be even faster if ARM11, ARM Cortex A8 or A9 processors were used and if it was configured with slightly more than 128MB RAM. How soon will Google release the $100 Google laptop?"

MSI Will Launch iPad Alternative 756

itwbennett writes "Underwhelmed by the iPad? Don't give up on tablets just yet, says blogger Peter Smith. MSI has a tablet coming in the second half of 2010 that measures up on price and size and addresses a lot of the iPad's most noted shortcomings. 'The iPad runs iPhone OS while the MSI runs Android,' writes Smith. 'That means the MSI will multitask of course, and Flash support in Android should be a given by launch time (though that isn't certain). It has a camera. It's running on an Nvidia Tegra2 chip which Ars Technica suggests puts it on par with the iPad's A4 as far as computing horsepower. And of course Android doesn't live in a walled garden.'" The post notes that the MSI device does not support multitouch in its built-in apps. Still, would an Android-powered iPad-alike tempt you?

Update: 01/29 17:58 GMT by KD : Dave Altavilla suggests Hot Hardware's coverage of Asus's recently announced tablet, also based on the Tegra2 chip.

2 Displays and 2 Workspaces With Linux and X? 460

Borov writes "I'm planning to buy a second monitor in near future and I was searching for ways to configure it under Linux. It seems there are two main ways: 1) to have one 'big' desktop, which means I have single workspace — changing virtual desktop switches both monitors or 2) to have separate X sessions for each display — which means I have separate workspaces, but I can't move applications between them. I need something in the middle — a separate workspace for each screen, so that I can have independent virtual desktops on each screen, but still have the ability to move applications between monitors (no need to strech one app across both of them). I've read that some tiling window managers can do this kind of thing, but I'd rather go with 'classical' window managers, like Openbox/Gnome/KDE or similar."

Ubuntu Moves To Yahoo For Default Firefox Search 370

An anonymous reader writes "Starting in Ubuntu's Lucid Lynx release, Firefox's default search engine will be switched from Google to Yahoo. The switch was made after Canonical 'negotiated a revenue sharing deal with Yahoo.' Google will still be available as a choice. Since Yahoo search is now powered by Microsoft's Bing, this would seem to mean that Microsoft will be paying people for using Ubuntu."

The Future of Portable Linux Distros 107

i_want_you_to_throw_ sends in a Tech Radar piece about the various portable Linux distributions, focusing on operating systems like Android, Chrome OS, and Ubuntu Netbook Remix. The article compares the distributions designed for similar purposes and discusses where they will likely go in the future. "As UNR is built on Ubuntu, it's highly likely that we'll see almost as many UNR respins as we have for the parent distribution. We've already seen one example in Jolicloud, and we'd put money on many community distributions, such as Linux Mint or Crunchbang offering a UNR overhaul alongside their standard desktop installations. It's also likely that Canonical will be able to forge stronger relationships with companies like Dell, which is already shipping a specific version of UNR on its Mini 9 platform. As Windows XP is phased out and the cost of bundling Windows 7 rises, manufacturers will be looking for a cheap and easily maintainable netbook OS, and UNR fits the bill admirably."
Education

NZ School Goes Open Source Amid Microsoft Mandate 305

Dan Jones writes "Kiwis have built an entire school IT system out of open source software, in less than two months, despite a deal between the New Zealand government and Microsoft that effectively mandates the use of Microsoft products in the country's schools. Albany Senior High School in the northern suburbs of Auckland has been running an entirely open source infrastructure since it opened in 2009. It's using a range of applications like OpenOffice, Moodle for education content, Mahara for student portfolios, and Koha for the library catalogue. Ubuntu Linux is on the desktop and Mandriva provides the server. Interestingly, the school will move into new purpose-built premises this year, which include a dedicated server room design based on standard New Zealand school requirements, including four racks each capable of holding 48 servers for its main systems. The main infrastructure at Albany Senior High only requires four servers, suggesting an almost 50-fold saving on hardware requirements."

Misa Digital Guitar Runs On Linux 125

conner_bw writes "Imagine strumming a guitar without any strings, on a touchscreen. Think the idea is too far-fetched? The Misa digital guitar claims to be exactly this. Overcoming the natural limitations of a traditional guitar, this new instrument eliminates the need to pluck strings while using the right hand to control sound. Specs: Linux kernel 2.6.31 (Gentoo); 24 frets; touchscreen; MIDI out; RJ-45 Ethernet. My favourite parts of the site are the FAQ (How do you SSH into the guitar?), and this quote from the developer: 'Because the software is open source I'm hoping people completely change the instrument and share new "firmware" with others. Different graphics, different control ideas etc. It would all be free of charge. So I'm hoping that happens as the instrument becomes more familiar.'" The developer, Michael, has not yet promised a delivery date or set a price for the instruments he is manufacturing.

Red Hat Support Continues To Flourish 215

ruphus13 writes "As the pure-play Open Source companies continue to dwindle, Red Hat has thrived through the recession. Its support revenues have grown 20+%, and account for 75+% of its revenues. 'Instead of the traditional strategy of selling expensive proprietary software licenses, as practiced by the Microsofts and Oracles of the world, Red Hat gets the vast majority of its revenues from selling support contracts. In the third quarter of last year, support subscriptions accounted for $164 million of its $194 million in revenue, up 21 percent year-over-year. All 25 of the company's largest support subscribers renewed subscriptions, even despite a higher price tag.'"

Nokia To Make GPS Navigation Free On Smartphones 300

mliu writes "In what is sure to be a blow to the already beleaguered stand-alone GPS market, Nokia, the global leader in smartphone market share, has released a fully offline-enabled free GPS navigation and mapping application for its Symbian smartphones. Furthermore, the application also includes Lonely Planet and Michelin guides. Unfortunately, the N900, which is beloved by geeks for its Maemo Linux-based operating system, has not seen any of the navigation love so far. With Google's release of Google Navigation for Android smartphones, and now Nokia doing one better and releasing an offline-enabled navigation application, hopefully this is the start of a trend where this becomes an expected component of any smartphone."

75% of Linux Code Now Written By Paid Developers 368

i_want_you_to_throw_ writes "During a presentation at Linux.conf.au 2010 in Wellington, LWN.net founder and kernel contributor Jonathan Corbet offered an analysis of the code contributed to the Linux kernel between December 24 2008 and January 10 2010. The Linux world makes much of its community roots, but when it comes to developing the kernel of the operating system, it's less a case of 'volunteers ahoy!' and more a case of 'where's my pay?'" It's not clear from the article why anyone should perceive a contradiction between having high ideals and getting paid to do something you enjoy.

Jeremy Allison Calls Microsoft Dangerous Elephant 306

oranghutan writes "At the annual Linux.conf.au event being held in Wellington, NZ, one of the lead developers for the Samba Team (and Google employee) Jeremy Allison described Microsoft as 'an elephant that needs to be turned to stop it trampling the open source community.' Allison has been an outspoken critic of the vendor since he quit Novell over a deal it did with Microsoft that he saw as dangerous to open source intentions. And now he has evolved his argument to incorporate new case studies to explain why Microsoft's use of patents and its general tactics on free software are harmful.

Benchmarks of Debian GNU/kFreeBSD vs. GNU/Linux 143

An anonymous reader writes "The Debian Squeeze release is going to be accompanied by a first-rate kFreeBSD port and now early benchmarks of this port have started coming out using daily install images. The Debian GNU/kFreeBSD project is marrying the FreeBSD kernel with a GNU userland and glibc while making most of the Debian repository packages available for kfreebsd-i386 and kfreebsd-amd64. The first Debian GNU/kFreeBSD benchmarks compare the performance of it to Debian GNU/Linux with the 2.6.30 kernel while the rest of the packages are the same. Results are shown for both i386 and x86_64 flavors. Debian GNU/kFreeBSD may be running well, but it has a lot of catching up to do in terms of speed against Linux."

Kernel Contributor Corbet Says Linux Community Is 'Intimidating' 177

An anonymous reader writes "Key Linux kernel contributor Jonathan Corbet has admitted the developer community can be intimidating and hard to break into. He highlighted the issue during his Linux.conf.au presentation on the Linux kernel. Corbet expressed concern about the exclusivity of the kernel community, but says it's doing well regardless. He said in a period of just over a year, 55,000 individual changes from 2,700 developers (representing 370 employers) were made to the kernel, equaling 2.8 million lines of code. Corbet called the process 'alive and active.'"

100% Free Software Compatible PC Launches 458

crimperman writes "The Open-PC project has announced that its first PC will be available at the end of February for €359. They claim the mini-ITX desktop machine is energy efficient, consumer ready, easy to upgrade, and — significantly — uses only hardware that has free software drivers available. As you'd expect, it comes with GNU/Linux which is running KDE (a €10 donation to the KDE project in included in the price). Interestingly all the key decisions on design, pricing etc. have been made by the community via online polls. The spec of the machine is pretty reasonable for the price: Atom 1.6GHz dual-core processor, 3GB RAM, 160GB HDD, Intel 950 graphics."

Ubuntu 10.04 Alpha 2 vs. Early Fedora 13 Benchmarks 157

Given that early benchmarks of the Lucid Lynx were less than encouraging, Phoronix decided to take the latest alpha out for a spin and has set it side-by-side with an early look at Fedora 13. "Overall, there are both positive and negative performance changes for Ubuntu 10.04 LTS Alpha 2 in relation to Ubuntu 9.10. Most of the negative regressions are attributed to the EXT4 file-system losing some of its performance charm. With using a pre-alpha snapshot of Fedora 13 and the benchmark results just being provided for reference purposes, we will hold off on looking into greater detail at this next Red Hat Linux update until it matures."

Powerful Linux ISP Router Distribution? 268

fibrewire writes "I'm building a Wireless ISP using commercial grade, low cost equipment. My main stumbling block is that I cannot find a decent open source ISP class routing distribution. Closest thing to even a decent tool is Ubiquiti's AIRControl — but even it doesn't play well with other network monitoring software. I've used Mikrotik's RouterOS for five years, but it just isn't built for what I need. I don't mind paying licensing fees, but $300K for a Cisco Universal Broadband Router is out of my budget. Has anyone seen any good open-source/cheap hardware/software systems that will scale to several thousand users?"

Mozilla Starts To Follow a New Drumbeat 226

ChiefMonkeyGrinder writes "Key, then, to the Drumbeat project is openness, specifically openness as applied to the Internet. That fits in well with the original impulses behind Mozilla and Firefox. The former was about transforming the Netscape Communicator code into an open source browser, and the latter was about defending open standards from Microsoft's attempt to lock people into Internet Explorer 6 and its proprietary approaches. Both Mozilla and Firefox have succeeded, but the threats have now changed."

$199 Freescale Tablet Design Runs Chromium OS 93

Charbax writes "This is an extensive video interview with Freescale's manager of software development about their integration of the Chromium OS onto their ARM Cortex A8 i.MX51-based $199 Tablet reference design. It seems to run smoothly and fast with multiple tabs. There's no touch screen support yet, so input is done through a USB keyboard and mouse for now, but the WiFi drivers are fine. Freescale is also demonstrating Android and Ubuntu versions. Those have a 3G SIM card reader built-in, an HDMI output and 720p video playback. The question is: will they be able to support Chrome browsing at full speed on the most JavaScript- and Flash-intensive websites and support a large amount of opened tabs?" The demonstration of the Chromium tablet begins at about 11:20 into the video. The Android and Ubuntu versions are displayed earlier.
