Learn Linux for free from August 1

ITWire - 12 min 36 sec ago

The Linux Foundation is offering its comprehensive Introduction to Linux course - normally $2,400 - for free.

The Linux Foundation's Intro to Linux course is a full, professionally-delivered course. Its usual price tag is $2,400 but is being offered for free from August 1st 2014.

For your money - or lack of money, in this case - you get over 40 to 60 hours of course work, taught by Dr Jerry Cooperstein, who oversees all training for the Linux Foundation.

To get the free course click on the words "Why do I have to pay? What if I want a free honor code certificate?" and the option to select the "Select Honor Code Certificate" option will show, which allows you to bypass the usual contribution fee.

{loadposition david08}The course outline lists 18 modules, through an introduction to Linux philosophy and components, the GUI, system configuration, command-line operations, finding documentation, file operations, and on through text editors, network operations, text manipulation and printing, shell scripting, processes, security and common apps.

Before taking the course it would be helpful to ensure you have Linux running on a computer (or virtual computer). If you have never done this before the Linux Foundation provides a helpful 16-page guide to get you up and going.

Sign up through edX and bolster your Linux skills. The course has no assumed knowledge except familiarity with computers and common software. If you can sign up for the course then you have as much experience as is required.

For the keen, you can register to get a certificate proving your completion and newly acquired Linux skills for $250.

HP updates Moonshot family

ITWire - 1 hour 12 min ago

HP has announced two new Moonshot servers as part of its ambitious program to change the way organisations do IT.

HP's Moonshot system is built around the idea of using large numbers of low-power servers in parallel to support scale-out workloads such as web serving and desktop virtualisation.

Several of these microservers are packaged into one 'cartridge', and multiple cartridges can be packed into one rack-mounted chassis.

A key aspect of Moonshot is that cartridges are built to suit particular applications, allowing the design to be simplified and thus reducing power requirements. HP calls them 'application-defined servers'.

{loadposition stephen08}As part of its New Style of IT concept, HP has added two new cartridges to the Moonshot family.

The Moonshot ProLiant m300 (pictured) is aimed at front-end Web applications, dedicated hosting and light weight analytics workloads.

HP officials said the new m300, based on the 2.4GHz Atom C2750 processor, delivers seven times greater performance and six times higher performance per watt than the previous generation.

The Moonshot ProLiant m700 is built for hosted desktop infrastructure workloads and is used in the HP ConvergedSystem 100 for Hosted Desktops which supports 180 hosted desktops from one chassis.

These hosted desktops provide the business graphics and multimedia performance of a traditional desktop PC, company officials claimed, while reducing the total cost of ownership by up to 44%.

Furthermore, Moonshot technology can reduce power costs by up to 63%, they said.

In related news, HP has opened a Discovery Lab in Singapore, allowing customers and partners in Asia Pacific and Japan to work on applications on Moonshot and traditional servers.

Discovery Lab resources can be used on-site or remotely.

"Organisations across the region are under enormous pressure to build an efficient infrastructure to grow, compete and be ready for what's next," said HP South Pacific enterprise group director and general manager Raj Thakur.

"Today's announcements demonstrate HP's continued commitment to transforming the server landscape with customer-inspired innovations to Moonshot servers that enable organisations to be faster, smarter and more efficient now and into the future."

Palm-sized mini PC projects display, uses IR for touch

LXer Linux News - 4 hours 7 min ago
TouchPico is prepping an Android 4.2 mini-PC that doubles as a pico-projector and approximates touch input via an infrared stylus and camera. It’s not enough to offer just another straight-ahead pico projector these days. Sprint’s recent, ZTE-built LivePro, for example, doubles as a mobile hotspot and features an embedded display, and Promate’s LumiTab is also a tablet. Now a startup called TouchPico offers a similarly Android-based TouchPico device that adds touch input to projected images.

Who will win? Watch Supermoon and Perseid meteor shower battle it out!

ITWire - 12 hours 36 min ago
The Perseid meteor shower is gearing up to show us a whole bunch of fireballs screaming across the August night sky in 2014. However, a Full Moon at its perigee (a Supermoon) will also be present. Who will win the visibility contest? Look up in the night sky in mid-August and find out!     The meteors from the Perseids will be traveling over 93,000 miles (150,000 kilometers) per hour before burning up in the Earth’s upper atmosphere and giving us a bright display as they race across the night sky.   Probably the best time to view the Perseids is the first half of August because by the middle of the month the bright glare from the Full Moon will overshadow the light of the meteor shower. The Moon becomes full on August 10. However, astronomers think it will be still be quite a show -- seeing a Full Moon and very bright fireballs in the same night sky.   Astronomers are calling this a Supermoon because it is a Full Moon and is at perigee (its closest point on its orbit around the Earth; which occurs on August 10), which makes it appear about 30 percent brighter than normal because it is about 14 percent closer than during regular Full Moons.   Therefore, the first week of August is probably the best time to view the Perseid meteor shower. At that time, only a sliver of the Moon is visible, which allows the Perseid fireballs to shine bright in the night sky.   {loadposition william08}However, even the glare of the Supermoon will not eliminate the visibility of the Perseid meteors. Bill Cooks of NASA’s Meteoroid Environment Office states, “the Perseids are rich in fireballs as bright as Jupiter or Venus. These will be visible in spite of the glare." (NASA: “Perseid Meteors vs. the Supermoon”)   The meteors of the Perseids are tiny space debris ejected from the Comet Swift-Tuttle. Tthe Perseids are named after the constellation Perseus because their radiant (the direction from which the shower seems to come from) lies in the same direction as Perseus. (See image above.)   The constellation Perseus is located in the northeastern part of the night sky. Look toward that part of the sky to see them streaking toward you.   Also called the Tears of Saint Lawrence, the Perseid meteors originate from the Comet Swift-Tuttle (formally known as 109P/Swift-Tuttle).   Italian astronomer Giovanni Virginio Schiaparelli (1835-1910) first identified that the comet is associated with the Perseid meteor shower in 1866.    Comet Swift-Tuttle, with a comet nucleus of 16 miles (26 kilometers) in diameter, was discovered independently by American astronomer Lewis A. Swift on July 16, 1862, and by American astronomer Horace Parnell Tuttle on July 19, 1862.   Page two continues with more on the Perseids meteor shower and the Supermoon.     The Perseids are visible from mid-July (around July 17) to late-August (August 24), with a peak in activity from August 9 to August 14. NASA says the peak is on the 11th, 12th, and 13th (see the mention of the NASA article on page 1).   During its peak, the frequency of meteors can reach 60 or more per hour -- in some years the frequency has reached 100 per hour.   Most sightings for the Perseid meteor shower will occur in the Northern Hemisphere. And, most will be seen in the pre-dawn hours.   As they collide with the Earth’s atmosphere, the meteors become visible to skywatchers (some call them shooting stars), but they will soon disappear at heights above the Earth of about 50 miles (80 kilometers).   NASA has an interesting YouTube video, shown above, called ScienceCasts: Perseid Meteors vs the Supermoon (http://www.youtube.com/watch?v=JkKzMAzT5fs&;feature=youtu.be).   Its caption states, “Which is brighter--a flurry of Perseid fireballs or a supermoon? Sky watchers will find out this August when the biggest and brightest full Moon of 2014 arrives just in time for the peak of the annual Perseid meteor shower.”

Android crypto blunder exposes users to highly privileged malware

LXer Linux News - 13 hours 2 min ago
The majority of devices running Google's Android operating system are susceptible to hacks that allow malicious apps to bypass a key security sandbox so they can steal user credentials, read e-mail, and access payment histories and other sensitive data, researchers have warned. The high-impact vulnerability has existed in Android since the release of version 2.1 in early 2010, researchers from Bluebox Security said.

The great Ars experiment—free and open source software on a smartphone?!

LXer Linux News - 14 hours 56 min ago
Android is a Google product—it's designed and built from the ground up to integrate with Google services and be a cloud-powered OS. A lot of Android is open source, though, and there's nothing that says you have to use it the way that Google would prefer. With some work, it’s possible to turn a modern Android smartphone into a Google-less, completely open device—so we wanted to try just that. After dusting off the Nexus 4 and grabbing a copy of the open source parts of Android, we jumped off the grid and dumped all the proprietary Google and cloud-based services you'd normally use on Android. Instead, this experiment runs entirely on open source alternatives. FOSS or bust!

6 open source tools for data journalism

LXer Linux News - 15 hours 53 min ago
When I was in journalism school back in the late 1980s, gathering data for a story usually involved hours of poring over printed documents or microfiche. A lot has changed since then. While printed resources are still useful, more and more information is available to journalists on the web. That’s helped fuel a boom in what’s come to be known as data journalism. At its most basic, data journalism is the act of finding and telling stories using data—like census data, crime statistics, demographics, and more.

Dev board targets Atom Z3000 tablet designers

LXer Linux News - 16 hours 50 min ago
Intel and Microsoft launched a community-backed, quad-core Atom Z3735G-based “Sharks Cove” SBC aimed at designers of Windows or Android tablets. As you might expect from the fact that the $299 Sharks Cove development board ships with a Windows Embedded 8.1 image, this is not an open source SBC — at least from the Windows OS perspective. However, it’s backed up by a SharkCove.org community site, which has posted hardware documentation, but currently lacks a forum. The board is available on pre-order from Mouser.

Has Toast lost its way?

ITWire - 17 hours 25 min ago

Toast 12 has been launched, but do you need to upgrade?

When I reviewed Toast 11 Titanium two years ago, I observed that the package was shifting away from its disc burning roots and becoming more of a media conversion utility.

If you weren't particularly excited by Toast 11 Titanium, Toast 12 Titanium ($129) is unlikely to cause more than a shrug.

As far as I can see from Roxio's description, all that's really new in this venerable Mac suite is a screen recording tool.

{loadposition stephen08}The ability to burn HD videos on DVDs is now a standard feature rather than being a $19.99 add-on, though that add-on is still required for Blu-ray authoring.

Then there are some extra templates and enhancements to the DiscCatalogMaker utility, but that's you're lot.

And they expect us to pay $89 to upgrade? That's not much of a saving for relatively little new functionality, especially as well-regarded screen capture software (eg, Screenium) is available for less.

It's much the same story with Toast 12 Pro. All that seems to be new is FaceFilter3 Standard, a tool for removing pimples and wrinkles from portrait photos and generally making the subject look better.

FaceFilter3 Standard sells for $37.99 in the Mac App Store, but it will cost you $129 to upgrade from Toast 11 Pro to Toast 12 Pro.

Toast 12 Pro, which costs $219, does include five other utilities: the screen recorder that's in the Titanium edition, plus HDR Express 2 (for creating HDR images), FotoMagico 3 RE (slideshows), iZotope Music & Speech Cleaner (clean up audio tracks), and SmartSound Sonicfire Pro 5.8 (create musical soundtracks). Photoshop Elements has disappeared.

If there are other improvements, Roxio hasn't done a good job of promoting them.

I won't be rushing to upgrade to Toast 12 Titanium. In nine months or so it'll probably feature in a software bundle that'll offer a better value way of acquiring the new version.
