  • Tips on How to Start Learning Linux
    Of course, most of the time, especially you need to solve a task at hand in a timely fashion, you will usually just find the quickest way that works for something, and probably not bother on how exactly does it work. These tips are for beginners, but mostly for those who like Linux as a whole and like to sacrifice some of their own time to go on a path of constant learning how it works.

  • How far will the Supreme Court go to stop patent trolls?
    What kinds of software—if any—deserve a patent?It's a basic question, and one that many thought would be resolved by now, especially since the issue came up in the US Supreme Court's 2010 Bilski decision. But Bilski left the legal landscape more confusing and fractured. This was illustrated in dramatic fashion last year, when the nation's top patent court, the US Court of Appeals for the Federal Circuit, practically split apart at the seams trying to decide if four patents on financial software held up. The Alice Corp. v. CLS Bank case resulted in ten judges writing seven different opinions and resolving nothing.
  • Supreme Court hears argument on a patent worthy of King Tut
    That was followed by Justice Stephen Breyer's question, which suggested the Alice patent is describing a method of settling accounts that is in fact ancient."I mean, imagine King Tut sitting in front of the pyramid where all his gold is stored, and he has the habit of giving chits away," said Breyer. "He hires a man with an abacus, and when the abacus keeping track sees that he's given away more gold than he has in storage, he says, stop.... How is that [the Alice patent] less abstract than King Tut, if we had the same thing with a grain elevator, if we had the same thing with a reservoir of water, if we had the same thing with my checkbook?"

  • Android development articles for iOS developers
    The online magazine objc.io has a new issue up - focusing on Android instead of iOS and OS X. Admittedly, this started out as an April Fools' joke. But we quickly realized that we actually could make a really good issue about this. After all, it's interesting to Objective-C developers to learn something about what development on the other major mobile platform is like, as well as what we can learn from it. A set of articles of specific interest to iOS developers wishing to get their toes wet on Android development. No politics, just code.
  • The new Mozilla CEO's political past is imperiling his present
    For the Internet community, the principles of free speech and equal rights are foundational. But in recent days, those issues are clashing at Mozilla, the nonprofit foundation and tech company behind the Firefox browser. At issue is Brendan Eich, a co-founder of Mozilla, inventor of the much used Javascript programming language and the newly appointed CEO of the company. Eich made a $1,000 donation to the campaign for California's Proposition 8, which defined marriage as only between a man and a woman. The donation had come to light in 2012, but fizzled. Opposing same-sex marriage is no different than opposing interracial marriage. As a Dutchman, it baffles me that an organisation like Mozilla appointed a man with such medieval ideas.
  • Apple's Cyclone microarchitecture detailed
    AnandTech on Apple's A7 processor: I suspect Apple has more tricks up its sleeve than that however. Swift and Cyclone were two tocks in a row by Intel's definition, a third in 3 years would be unusual but not impossible (Intel sort of committed to doing the same with Saltwell/Silvermont/Airmont in 2012 - 2014). Looking at Cyclone makes one thing very clear: the rest of the players in the ultra mobile CPU space didn't aim high enough. I wonder what happens next round. This is one area where Apple really took everyone by surprise recently. When people talk about Apple losing its taste for disruption, they usually disregard the things they do not understand - such as hardcore processor design.
  • Round two: Apple, Samsung suit up for another patent war
    The Verge, summarising the first US patent lawsuit between Apple and Samsung: Apple was awarded just over $1 billion in damages, though that figure was later cut down to $939.8 million after the judge pointed out errors in the way the jury did its math. Those damages were retried, and came in lower than the original figure, though the entire amount has since been appealed, and Samsung hasn't paid a penny. Alongside that, Apple and Samsung failed to win bans against one another's products in the US, making the first trial seem like nothing more than a legal spectacle. Or, just call it what it is: an abject failure on both company's sides, and a huge waste of money that could have gone to product development, higher salaries, or even shareholder returns. Two gigantic and hugely profitable companies using despicable weaponry - and all, for, nothing. But in the midst of all that was a very real threat: another lawsuit, one that targeted more successful devices from both companies, and used easy-to-understand patents covering basic software features. Apple filed it against Samsung in February 2012, targeting 17 devices. Samsung responded in kind, and this week the pair go head to head once again; the outcome could be very different. Here's what to expect over the next weeks and months as these two titans clash again in California's courts. So, prepare for another week of lawyers laughing all the way to the bank, while two companies with more money than they know what to do with waste precious time of the US justice system that could be spent elsewhere, and better. Let the cheering contest continue. Which faceless corporation that cares none about you do you root for?
  • First Sailfish OS build for Nexus 4 released
    Jolla has released the first builds of Sailfish OS for the Nexus 4. Installation isn't exactly easy, and the builds are far, far from complete or stable (the display is even watermarked to say as such), but it does constitute Sailfish' first steps beyond the Jolla phone. Take note of all the disclaimers - and if you're okay with taking the plunge, have fun.
  • 'Announcing the Office you love, now on the iPad'
    We know you've been wanting it, and starting today, you can download Word, Excel and PowerPoint for iPad from the App Store. The apps have the robust capabilities and familiar look and feel that is unmistakably Office, while offering a fantastic touch experience built from the ground up for iPad. With the free versions of the apps, you can read your Word documents, view your Excel data and present with PowerPoint. Your documents will look as good as they do on your PC and Mac®, and better than ever on your iPad. With an Office 365 subscription, you can edit and create new documents with the iPad. It looks pretty good, and as a heavy Office users, I can't wait until this hits Android tablets. On a related note: Office for phones (both iOS and Android) has gone completely free. I'd be remiss if I didn't mention that iOS got touch Office before Windows. I feel like I'm in the twilight zone.
  • GNOME 3.12 released
    Major new features for this release include a significant update to the experience for finding and installing applications, as well as major facelifts for the Videos and gedit applications. Those who have high resolution displays will benefit from greater support, and users will experience better start up times as well as more efficient resource usage. They will also be able to quickly organize their applications with the new application folders feature. I remember a time when GNOME and KDE releases were big deals here. Feels like eons ago, a distant memory from an irrelevant past.
  • Virtual reality is going to change the world
    Notch was working with the Oculus team to bring Minecraft to the Rift - and then the Facebook news hit. He immediately cancelled the project. I definitely want to be a part of VR, but I will not work with Facebook. Their motives are too unclear and shifting, and they haven’t historically been a stable platform. There’s nothing about their history that makes me trust them, and that makes them seem creepy to me. And I did not chip in ten grand to seed a first investment round to build value for a Facebook acquisition. It seems like Notch sums up the general response to Facebook acquiring Oculus pretty well.
  • Steve Jobs' brutal response after getting a Google employee fired
    In early March, 2007, as Google was expanding fast and furiously, one of its recruiters from the "Google.com Engineering" group made a career-ending mistake: She cold-contacted an Apple engineer by email, violating the secret and illegal non-solicitation compact that her boss, Eric Schmidt, had agreed with Apple's Steve Jobs. What happened next is just one of many specific examples of how people's lives were impacted by the Techtopus wage-theft cartel that was taken down by the Department of Justice antitrust division, and is currently being litigated in a landmark class action lawsuit. This story sent shivers down my spine. What a bunch of horrible, unethical scumbags. Sadly, their criminal behaviour won't really have any meaningful consequences. These people reside above the law.
  • Facebook to acquire Oculus
    Facebook today announced that it has reached a definitive agreement to acquire Oculus VR, Inc., the leader in immersive virtual reality technology, for a total of approximately $2 billion. This includes $400 million in cash and 23.1 million shares of Facebook common stock (valued at $1.6 billion based on the average closing price of the 20 trading days preceding March 21, 2014 of $69.35 per share). The agreement also provides for an additional $300 million earn-out in cash and stock based on the achievement of certain milestones. What the heck does Facebook need this for? Great news for the Oculus men and women though.

  • Sailfish OS builds available for Nexus 4

    Owners of Nexus 4 mobile phones now have yet another open source operating system that they can install: Sailfish OS, the Maemo/MeeGo descendant being developed by the team at Jolla.

The builds are far from complete; as the release notes explain, voice calls are not yet enabled, nor are "Sensors, Device clock/alarms, Reset device, Bluetooth, USB control + MTP, Bluetooth, WLAN hotspot, Camera (photography, video recording), and video playback.

  • Best Quotes from the Linux Kernel Developer Panel (Linux.com)
    Linux.com presents a few quotes from the Kernel Developer Panel at the Linux Foundation Collaboration Summit. Kernel developers Greg Kroah-Hartman, Jens Axboe, Dave Chinner, Matthew Garrett, and Mel Gorman participated in the panel discussion, moderated by Jon Corbet. A video accompanies the article.

    The Linux kernel is one of the largest collaborative software projects in the history of the world and has almost nothing in the way of formalized management structure. We have people who have a strong operating systems background who have been contributing code, and then we have people like me. I have a background in fruit fly genetics and yet someone lets me get close to the Linux kernel; this seems wrong. And then we have people who are genuinely kids in their bedroom. It's a miracle it works as well as it does. We should be astonished that we're able to get it so right so much of the time.

    Next week, from Monday the 31st of March to the 4th of April (Friday), developers from the major Linux desktops (GNOME, KDE, Unity and RazorQt) will meet in Nuremberg for the second Freedesktop Summit.

    The summit is a joint technical meeting of developers working on 'desktop infrastructure' on the major Free Desktop projects. The event aims to support collaboration between projects by discussing specifications and the sharing of platform-level components. David Faure will be KDE's primary representative at this year's summit.

    Last year's event led to agreements related to D-Bus and management of trash folders. It also mapped the way forward for joint development and management of specifications that are important to multiple providers of desktop software.

    Like last year, the event is supported by SUSE.

  • KDE wins Linux New Media Readers Choice Award 2014

    Last week at CeBIT, KDE won the Linux New Media Readers Choice Award 2014 (link to German language Linux Magazine) for the best Linux Desktop Environment. 46% of the readers of Linux New Media's global publications voted for KDE. Runner-ups were GNOME with 18% and XFCE with 13%. Other awards went to CyanogenMod, Raspberry Pi, Bitcoin, Puppet, Tor and Git.

    Cornelius Schumacher, President of KDE e.V. received the award on behalf of the KDE Community from Mathias Huber, Editor at Linux Magazine. The video of the award ceremony will be available on the Linux Magazine web site later.

    KDE is delighted to receive the award. Hundreds of our volunteers dedicate hard work and passion to creating free software for end users and it is great to be recognized in this way. KDE's software runs on tablets and phones, Windows and Mac OS, but the core of what the KDE Community is doing is still focused on the Linux Desktop. Continuous work over many years has made KDE's Plasma the reliable choice of the majority of Linux Desktop users.

  • Applications 4.13 Coming Soon, Help Us Test!

    Last week, the first beta of Applications and Platform 4.13 was released. This week, beta 2 is coming. The openSUSE team has already asked its users to start the testing engines and that request extends to the entire community of KDE users!

    What's to be tested?

    Let's go over a list of major and minor changes in this release, and areas where developers have explicitly asked us for help.

    Search

    A major new improvement is the introduction of KDE’s next generation Semantic Search. This makes search faster, saves memory, improves stability, and generates more reliable search results. And it could use a good testing.

    Various applications use the search abilities, most notably Dolphin and KDE PIM (see the next section). Also tagging (Gwenview!) and KRunner (Alt-F2 run command dialog) can use some attention.

    Some of your existing data will need to be migrated from the current Nepomuk backend to the new 'Baloo' backend. Running the nepomukbaloomigrator should take care of that. The old Nepomuk support is considered “legacy” (but it is still provided). The programs that have not yet been ported to the new architecture have Nepomuk integration disabled. One significant regression is file-activity linking, which will not work until KDE Applications and Platform 4.14. If you rely on this feature, we recommend not upgrading at this time. For the final release, distributions might choose to optionally have the old search (Nepomuk) available.

    Kontact

    The Kontact Suite (email, calendaring, contacts and more) benefits from the improvements in search; there is also a new quick filter bar and search. IMAP will be more reliable, and performance should be massively improved. There is also a brand new sieve editor and integration with cloud storage functions, where Kontact can automatically put big attachments on Box/DropBox/Hubic/Kolab/ownCloud/UbuntuOne/WebDav/YousendIt and link to them.

    Okular, Kate and Umbrello

    Document viewer Okular has a lot of new features like tabs, media handling and a magnifier, improved Find and Undo/Redo.

    Text editor Kate has gotten a lot of attention, so there are many new features in the areas of further VIM style support, bracket matching, highlighting and more. You can read the blogs on the Kate site and test some of that awesome.

    The UML modeling application Umbrello received some improvements and bugfixes. If you use it, now is a good time to help out a little and see if it works better! There is new duplication of diagrams and improvements to the context menus (which only shows relevant actions).

    Education and Games

    We received a special request from developer Ian Wadham:

    Please give the new version of Palapeli jigsaw puzzling a whirl. This contribution to KDE is my celebration of 50 years as a programmer. I started in April 1964.

    If you ever enjoyed jigsaw puzzles, especially those 500 and 1,000 piece boxed puzzles, please take a look at the new version of Palapeli. The main thing is its attempt to make solving large puzzles (300 to 10,000 pieces) possible, realistic and enjoyable on a small screen. You can make your own large puzzle from any photo or picture file you fancy.

    So I am very interested in *usability* feedback (look and feel). As well as bugs, of course. I am currently "testing" on a 10,000 piece puzzle ... The Handbook changes should be finished in a few days, but there is already a long help message that appears when you start a large puzzle (> 300 pieces).

    The new features are described, but in a technical way, in the usual place.

    Have fun, everyone.

    Artikulate (technical information) is a brand new application in KDE Edu and will have its first official release with KDE Applications 4.13. Find some information about it on community.kde.org.

    And how does that work?

    Testing follows these steps:

    1. set up your testing environment
    2. pick something to test
    3. test it
    4. back to 2 until something unexpected/bad happens
    5. check if what you found is really a bug
    6. file the bug

    You're not alone!

    In KDE, testing is not only an individual action by our users but it's also coordinated through the KDE Quality team. That does not mean you must work or coordinate with them, but it sure helps! You can reach them on IRC, as well as on their mailing list.

    The testing of this beta is also coordinated on this forum page for those more comfortable on forums.

    The KDE Quality Team wiki page is worth a read if you're unexperienced. There is even a real tutorial on becoming a KDE tester!

    Get the beta and prepare

    To get testing, you can either build the source of the Beta or RC, or grab packages for your distribution. If your distro is not on that list but you know there are packages, you can add them there!

    The second step is to create a testing user account. We recommend this to prevent destroying data on your current account. Many users also use a separate installation of KDE software on a separate partition.

    On most flavors of Linux, creating a new user is easy. On the command line, it goes a bit like this (as root):

    • useradd -m kde-test
    • passwd kde-test

    And now you've created a user kde-test and given the account a password. Just switch user accounts (menu - leave - switch user or Alt-F2 - switch) and have fun testing!

    The real testing

    Testing is a matter of trying out some scenarios you decide to test, for example, pairing your Android phone to your computer with KDE Connect. If it works – awesome, move on. If it doesn't, find out as much as you can about why it doesn't and use that for a bug report.

    This is the stage where you should see if your issue is already reported by checking on the forum, IRC channel or mailing list. It might even be fixed, sometimes! It can also be fruitful to contact the developers on the relevant mailing list.

    Finally, if the issue you bump into is a clear bug and the developers are not aware of it, file it on bugs.kde.org.

    How else can I help?

    Another useful contribution is triaging bugs:

    • determine if it's really a bug (it can be reproduced)
    • find out which component has the bug and
    • assign or cc the maintainer of that component

    If you can’t reproduce a bug, the bug might have to be marked as “WORKSFORME” or “NEEDINFO” if you can’t reproduce it due to a lack of information. And in some cases, the bug report is plain wrong (“Plasma doesn’t make coffee“) and must be closed as “INVALID”. You can find more information in the Ultimate Bug Triaging Guide. As long as you can't close bugs on bugzilla, you can just add your information as comments and they will be picked up by a maintainer – it is just as useful!

    It is a big help!

    We're very grateful for your help in this. Not all areas of our many applications receive the same amount of care and attention, and there may not always be an immediate reply to bug reports. However, developers greatly appreciate the attention given to their applications by users and testers.

    KDEntomologists rule!

  • Conf.kde.in 2014 - Knowledge. Power. Freedom.

    conf.kde.in 2014 was held at DA-IICT (Dhirubhai Ambani Institute of Information and Communication Technology) in Ghandinagar, India during the weekend of 22nd to 24th February. It was a big mashup of many different cultures with speakers and delegates from Europe, the USA and different parts of India. A platform for the exchange of ideas, and spontaneous discussions about goals and thoughts regarding open source as well as technological advancements. Also how to make paper planes.

    What came before

    Conf.kde.in was first organized in 2011 in Bangalore; last year a KDE India Meetup took place at DA-IICT. Both of those helped bring forth an expanded conf.kde.in 2014. The growing KDE community in India welcomed new, cheerful friends. And the open source community in India welcomed a new generation of stalwarts.


    Group discussion

    Where it was

    Dhirubhai Ambani Institute of Information and Communication Technology (DA-IICT), Gandhinagar is an institution of higher learning located in one of the most thriving technological hubs of western India. It has been fostering young minds in the fields of computer science and information technology for many years and features an active local community. It was the perfect location for conf.kde.in to reach out to more young minds. With the conference at the institutional level, KDE and top talent made a solid connection.


    Group photo!

    What it was all about

    conf.kde.in 2014 was a fertile environment for getting people started with open source contribution, telling them about KDE technology and the community, introducing them to various applications, answering questions, and appealing to them to make the switch to open source. There were about 260 attendees for the event.


    Peter in action

    Starting

    The first day - the 21st of February saw the start of the conference with a talk by Pradeepto Bhattacharya (a member of the KDE e.V. Board) on the essence of the KDE Community. That was followed by a Qt hands-on session, with the students experiencing the power of Qt by fiddling with it, rather than just listening and trying to imagine how to use it. Some people couldn't keep up with the pace, but by the end of the day, almost everyone had a fully functioning Linux system running on their laptop and was beginning to explore the power of Open Source. There was a general level of satisfaction with the learning opportunities, no matter the person's starting skill level. People's willingness to help others made a big difference.

    Going deeper

    The second day - on the 22nd of February there was a huge line up of talks - spread out over different realms of open source. The sessions by Sinny Kumari, Chandan Kumar, Samikshan Bairagya, Smit Shah, Shubham Chaudhary were specific to the projects they are working on—Plasma Media Center, Artikulate (the language trainer application), Localization Team Management tool, KDE Multimedia and others. There was also some informal bug solving. The point of these sessions was to introduce the students to various KDE projects, projects that students have worked on previously as a part of the Google Summer of Code, the Season of KDE and other mentoring programs. This helped them understand real life applications of coding techniques and skills, and the value of direction and guidance from mentors. It also showed them how to get started contributing to open source.


    Lunch!

    The talks by Nikhil Marathe, Vishesh Handa, Siteshwar Vashisht and Shantanu Tushar Jha went deeper into specifics and covered technical details of various KDE applications. They covered topics such as memory and synchronization management with RAII, the Mer Project, Baloo (dealing with meta data and search indexing). These presentations expanded the attendees' horizons and helped them explore advanced issues and technologies.

    The non-technical talks—on various facets of open source and FOSS communities—were given by Kévin Ottens and Jos Poortvliet. They talked about Free and Open Source Software and how its principles operate within the KDE Community. Their presentations emphasized the practical aspects of FOSS on KDE's work and beliefs. Conference participants got a clear view into KDE as an open source organization, further broadening their horizons.

    On February 23rd, Bhushan Shah, Sayantan Datta, Rishabh Arora, Punit Mehta and Peter Grasch talked about their KDE projects which are (respectively):

    • Plasma Workspace
    • Digikam - photo editing
    • KStars - astronomical sky guide
    • Khipu - mathematical graph plotting
    • Simon - speech recognition software

    Students could choose a project and experiment with code, documentation and testing. Of course, everyone had the opportunity to use open source technology and experience its power. Kévin Ottens and Prashant Udupa spoke briefly about specific technologies such as C++11 and Generic Component Framework.


    Paper planes

    Closing thoughts

    The primary goal of the conference was to encourage people to get involved with open source and to understand its power and its reach. We also wanted to help them get started by teaching them the basics and by getting them to know more about KDE. When the conference was over, it didn't matter how many lines of code anyone could understand or even actually write. If some people were convinced of the magic of open source and of KDE, and are now willing to be contributors to this noble cause even if only slightly, then the event accomplished its aim. Events, speakers and mentors like these add fuel to the fire inside. Students were inspired to reach out and experience the power of free and open source technology.

    Be free. Live KDE.

    Editors' note: Also, on the last day, a competition in building paper airplanes took place. No correlation was found between C++ coding skills and the distance airplanes flew.
