Ask Slashdot: Linux Database GUI Application Development? 264

New submitter msubieta writes I have been developing some applications to use in small businesses using Windows and SQL Server. I would like to move on and start doing the same thing in Linux. I have looked at several Frameworks/Databases/Development environments and I really don't know what is the best/simplest/fastest to learn approach. I use VS and C# mostly, although I could easily go back to C++. I found Qt and GTK+ are the most common frameworks, but they seem to lack controls that deal with datasets and stuff (sorry, spoiled by the .net form controls), but I also know that I could use Mono in order to make the jump. I would have no problem on moving to MySQL, as I have done quite a lot of work on that side, and I would like to stick with the traditional client server application, as I find it easier to maintain, and a whole lot more robust when it comes to user interaction (web apps for POS applications don't seem to be the right way to go in my view). Any suggestions/comments/recommendations?

KDE Frameworks 5.3 and Plasma 2.1 – First Impressions 84

jones_supa writes Ken Vermette has done a write-up on his experience with the new KDE desktop encompassing Frameworks 5.3 and Plasma 2.1. For starters, some patience is still needed for apps to be ported to KF5, and most of them will be KF4-based for now. Many of the widgets you may have used don't exist yet either, but the good news is that the Plasma goodies which do make an appearance are universally improved. The new search widget is shockingly fast and the notifications tray has been reworked. Visual outlook of desktop has been simplified and things don't feel so tightly packed together anymore. The system settings application has been completely regrouped more by goal than underlying mechanics. Unfortunately the desktop stability leaves a lot to desire: there was several crashes and Plasma had at one point managed to forget colour and wallpaper settings. However the developers seem to be knowing what they are doing, and there's a real feeling that this software will reach rock-solid stability very quickly given the state of it as it stands.

Sloppy File Permissions Make Red Star OS Vulnerable 105

An anonymous reader writes: Red Star OS Desktop 3.0, the official Linux distro of North Korea, which recently found its way onto torrents and various download sites in form of an ISO image, is interesting for a number of reasons, including its attempt to look like commercial operating systems (currently OS X, earlier versions mimicked the Windows GUI). Hackers are also poking Red Star for security vulnerabilities. An pseudonymous researcher noted in a post to the Open Source Software Security (oss-sec) mailing list, that the OS has one significant security hole: Red Star 3.0 ships with a world-writeable udev rule file /etc/udev/rules.d/85-hplj10xx.rules (originally designed for HP LaserJet 1000 series printers) which can be modified to include RUN+= arguments executing arbitrary commands as root by Udev. In the post he also mentions how the older Red Star 2.0 shipped with another schoolboy mistake: /etc/rc.d/rc.sysinit was world-writeable.

Ask Slashdot: Best Software To Revive PocketPCs With Windows Mobile 5-6? 110

An anonymous reader writes I recently got my hands on some amazing (at their time) pieces of technology, PocketPCs from the 2005-2007 era. All run with Windows Mobile 5 or 6, have storage SD cards (up to 4GB), 300 to 600 MHz ARM CPUs and 64-124MB of RAM/ROM. GPS chip is Sirf STAR III. I want to know what software you would install on them. Maybe a good Linux with GUI - if anyone can point on how to make it work. Creating some apps myself would be nice, but dunno where to start for WM5. One of my ideas was to use them as daily organizer / shopping list / memory games for people that don't own smartphones. So if anyone remembers such apps, I'd appreciate a reference. Tips or ideas for memory training or smart games are also highly welcomed. The power within these toys is simply unused and it's a shame!

Unity 8 Will Bring 'Pure' Linux Experience To Mobile Devices 125

sfcrazy writes If you have tried the live images of Ubuntu Next you may worry that Canonical is trying to do a Windows 8 with Ubuntu. That's not true. There is no need to worry though: A great deal of work is happening at a deeper level that may not have yet surfaced. It will surface eventually, however. Will Cooke of Canonical clarifies: "We are trying to make it clear that Unity 8 desktop will look like the traditional desktop and will behave like a normal desktop. We are very aware that our users expect a normal desktop there."

Unity 8 will offer the traditional desktop interface when it detects a desktop. The same OS will switch to a touch-based interface on touch-based devices such as tablets and smartphones.

Windows 10 To Feature Native Support For MKV and FLAC 313

jones_supa writes Windows Media Player is going to become a more useful media player for those who want to play geeky file formats. Microsoft has earlier confirmed that Windows 10 will come with native support for Matroska Video, but the company now talks about also adding FLAC support. Microsoft's Gabriel Aul posted a teaser screenshot in Twitter showing support for this particular format. It can be expected to arrive in a future update for people running the Windows 10 Technical Preview. Not many GUI changes seem to be happening around Media Player, but work is done under the hood.

Ars Dissects Android's Problems With Big Screens -- Including In Lollipop 103

When it comes to tablets, Google doesn't even follow its own design guidelines." That's the upshot of Ars Technica writer Andew Cunningham's detailed, illustrated look at how Android handles screens much larger than seven inches, going back to the first large Android tablets a few years ago, but including Android 5.0 (Lollipop) on the Nexus 10 and similar sized devices. Cunningham is unimpressed with the use of space for both practical and aesthetic reasons, and says that problems crop up areas that are purely under Google's control, like control panels and default apps, as well as (more understandably) in third party apps. The Nexus 10 took 10-inch tablets back to the "blown-up phone" version of the UI, where buttons and other UI stuff was all put in the center of the screen. This makes using a 10-inch tablet the same as using a 7-inch tablet or a phone, which is good for consistency, but in retrospect it was a big step backward for widescreen tablets. The old interface put everything at the edges of the screen where your thumbs could easily reach them. The new one often requires the pointer finger of one of your hands or some serious thumb-stretching. ... If anything, Lollipop takes another step backward here. You used to be able to swipe down on the left side of the screen to see your notifications and the right side of the screen to see the Quick Settings, and now those two menus have been unified and placed right in the center of the screen. The Nexus 10 is the most comfortable to use if it's lying flat on a table or stand and Lollipop does nothing to help you out there.

GTK+ Developers Call For Help To Finish Cross-Platform OpenGL Support 89

jones_supa writes OpenGL support under GTK is getting into good shape for providing a nice, out-of-the-box experience by default on key platforms for the GTK+ 3.16 / GNOME 3.16 release in March. For a few weeks now within mainline GTK+ has been native OpenGL support and as part of that a new GtkGLArea widget for allowing OpenGL drawing within GTK applications. Since that initial work landed, there's been more GTK+ OpenGL code progressing that right now primarily benefits Linux X11 and Wayland users. While good progress is being made and improvements still ongoing to the GNOME toolkit, GNOME developers are requesting help in ensuring other GTK+ backends can benefit from this OpenGL support. If you are using or planning to use GTK+ 3 on Windows or OS X, and you know how to use OpenGL on those two platforms, please consider helping out the GTK+ developers by implementing the GdkGLContext API using WGL and AppleGL.

Android 5.0 'Lollipop' vs. iOS 8: More Similar Than Ever 178

Nerval's Lobster writes With the debut of Android 5.0 (also known as Lollipop, in keeping with Google's habit of naming each major OS upgrade after a dessert), it's worth taking a moment to break down how the latest version of Google's mobile operating system matches up against Apple's iOS 8. After years of battle, the two are remarkably similar. So while nobody would ever confuse Android and iOS, both Google and Apple seem determined to go "flatter" (and more brightly colored) than ever. Whether or not you agree with their choices, they're the cutting edge of mobile UX design. The perpetual tit-for-tat over features has reached a climax of sorts with Lollipop and iOS 8: both offer their own version of an NFC-powered e-wallet (Apple Pay vs. Google Wallet), a health app (Apple's Health app vs. Google Fit), car-dashboard control (Android Auto vs. CarPlay), and home automation. That's not to say that the operating systems are mirror images of one another, but in terms of aesthetics and functionality, they'll be at near-parity for most users, albeit not for those users who enjoy customizing Android and hate Apple's "walled garden." (Related: Lots of reviews are popping up for Google's new Nexus 6, one of the first phones to come with the newest Android; TechCrunch's is typical, in that reviewer Greg Kumparak has high praise for the Lollipop UI, but found himself nearly dropping the device because of its size and texture.)

GNOME Project Seeks Donations For Trademark Battle With Groupon 268

Drinking Bleach writes Groupon has released a tablet-based point of sale system called Gnome, despite the well-known desktop environment's existence and trademark status. This is also not without Groupon's internal knowledge of the GNOME project; they were contacted about the infringement and flatly refused to change the name of their own product, in addition to filing many new trademark applications for theirs. The GNOME project is seeking donations to help them in a legal battle against these trademark applications, and to get Groupon to stop using their name. They are seeking at least $80,000 to challenge a first set of ten trademark applications from Groupon, out of 28 applications that have been filed.

Kubuntu 15.04 Will Be Based On KDE5 45

jones_supa writes Kubuntu Vivid is the development name for what will be released in April next year as Kubuntu 15.04. The exciting news is that following some discussion and some wavering, the Kubuntu team will be switching to Plasma 5 by default. They claim that it has shown itself as a solid and reliable platform and it's time to show it off to the world. There are some bits which are missing from Plasma 5 which are planned to be filled in over the next six months. As another technical detail, Debian git is now used to store the packaging in a Kubuntu branch, so hopefully it will be easier to share updates.

The Classic Control Panel In Windows May Be Gone 347

jones_supa writes In Windows 8, there was an arrangement of two settings applications: the Control Panel for the desktop and the PC Settings app in the Modern UI side. With Windows 10, having the two different applications has started to look even more awkward, which has been voiced loud and clear in the feedback too. Thus, the work at Microsoft to unify the settings programs has begun. The traditional Control Panel is being transformed to something temporarily called "zPC Settings" (sic), which is a Modern UI app that melts together the current two settings applications.

More Eye Candy Coming To Windows 10 209

jones_supa writes Microsoft is expected to release a new build of the Windows 10 Technical Preview in the very near future, according to their own words. The only build so far to be released to the public is 9841 but the next iteration will likely be in the 9860 class of releases. With this new build, Microsoft has polished up the animations that give the OS a more comprehensive feel. When you open a new window, it flies out on to the screen from the icon and when you minimize it, it collapses back in to the icon on the taskbar. It is a slick animation and if you have used OS X, it is similar to the one used to collapse windows back in to the dock. Bah.

Apple Doesn't Design For Yesterday 370

HughPickens.com writes Erik Karjaluoto writes that he recently installed OS X Yosemite and his initial reaction was "This got hit by the ugly stick." But Karjaluoto says that Apple's decision to make a wholesale shift from Lucida to Helvetica defies his expectations and wondered why Apple would make a change that impedes legibility, requires more screen space, and makes the GUI appear fuzzy? The Answer: Tomorrow.

Microsoft's approach with Windows, and backward compatibility in general, is commendable. "Users can install new versions of this OS on old machines, sometimes built on a mishmash of components, and still have it work well. This is a remarkable feat of engineering. It also comes with limitations — as it forces Microsoft to operate in the past." But Apple doesn't share this focus on interoperability or legacy. "They restrict hardware options, so they can build around a smaller number of specs. Old hardware is often left behind (turn on a first-generation iPad, and witness the sluggishness). Meanwhile, dying conventions are proactively euthanized," says Karjaluoto. "When Macs no longer shipped with floppy drives, many felt baffled. This same experience occurred when a disk (CD/DVD) reader no longer came standard." In spite of the grumblings of many, Karjaluoto doesn't recall many such changes that we didn't later look upon as the right choice.

Robot SmackDowns Wants To Bring Robot Death Matches To an Arena Near You 82

Business Insider profiles Andrew Stroup, Gui Cavalcanti and Matt Oehrlein, who are trying to get off the ground a robot competition league, called Robot SmackDowns. The idea, as you might guess from the name, is to showcase violence and drama to draw on the crowd-appeal of wrestling, NASCAR, and monster truck rallies: this is definitely not Dean Kamen's FIRST — it's giant mechanical beasts shooting at and otherwise trying to destroy each other. And it's not quite right to call them robots in the usual sense; they're more like mecha: "In a MegaBots battle, a two-member team sits inside the bot's upper torso, where the controls systems are housed. Although the co-founders assure me that the pilot and gunner are well protected inside, the situation presents a heightened suspense. Each 15,000-pound robot is equipped with six-inch cannons inside its arms that fire paint-filled missiles and cannon balls at 120 miles per hour. Good aim can cause enough damage to jam its opponent's weapons system or shoot off a limb." They'll be launching a Kickstarter campaign soon; according to the article, "Assuming it raises enough money to build a fleet, [the company's] plan is to take the bots on the road. They will tour the country, face off in epic battles against other MegaBots, and build a fan base. Stroup says (without giving specifics) networks have reached out and will closely watch how MegaBot, Inc.'s upcoming Kickstarter campaign performs. The possibilities for distribution seem endless, though the team is tight-lipped about the exact direction it's headed."

Data From Windows 10 Feedback Tool Exposes Problem Areas 147

jones_supa writes: Two weeks in, and already a million people have tried out Windows 10 Technical Preview, reports Microsoft, along with a nice stack of other stats and feedback. Only 36% of installations are occurring inside a virtual machine. 68% of Windows 10 Technical Preview users are launching more than seven apps per day, with somewhere around 25% of testers using Windows 10 as their daily driver (26 app launches or more per day). With the help of Windows 10's built-in feedback tool, thousands of testers have made it very clear that Microsoft's new OS still has lots of irksome bugs and misses many much-needed features. ExtremeTech has posted an interesting list of the most popular gripes received, them mostly being various GUI endurances. What has your experience been with the Technical Preview?

KDE Releases Plasma 5.1 60

jrepin notes the release of KDE Plasma 5.1. Quoting the release announcement: KDE Plasma 5.1 sports a wide variety of improvements, leading to greater stability, better performance and new and improved features. Thanks to the feedback of the community, KDE developers were able to package a large number of fixes and enhancements into this release, among which more complete and higher quality artwork following the new-in-5.0 Breeze style, re-addition of popular features such as the Icon Tasks taskswitcher and improved stability and performance.

Those traveling regularly will enjoy better support for time zones in the panel's clock, while those staying at home a revamped clipboard manager, allowing you to easily get at your past clipboard's content. The Breeze widget style is now also available for Qt4-based applications, leading to greater consistency across applications. The work to support Wayland as display server for Plasma is still ongoing, with improved, but not complete support in 5.1. Changes throughout many default components improve accessibility for visually impaired users by adding support for screenreaders and improved keyboard navigation. Aside from the visual improvements and the work on features, the focus of this release lies also on stability and performance improvements, with over 180 bugs resolved since 5.0 in the shell alone."

KDE's UI To Bend Toward Simplicity 184

sfcrazy (1542989) writes "KDE Software is often criticized for being too complicated for an average user to use. Try setting up Kmail and you would know what I mean. The KDE developers are aware of it and now they are working on making KDE UI simpler. KDE usability team lead Thomas Pfeiffer Thomas prefers a layered feature exposure so that users can enjoy certain advanced features at a later stage after they get accustomed to the basic functionality of the application. He quotes the earlier (pre-Plasma era) vision of KDE 4 – "Anything that makes Linux interesting for technical users (shells, compilation, drivers, minute user settings) will be available; not as the default way of doing things, but at the user's discretion."

Fedora To Get a New Partition Manager 170

sfcrazy writes Developer Vratislav Podzimek has announced the next-gen partition manager for Fedora, blivet-gui. It is eventually going to replace GParted, the most popular GUI based partition manager, found in all major distros. The new tool is named blivet-gui after the blivet python library (originally Anaconda's storage management and configuration tool). The need of a new partition manager stems from the fact that none of the existing GUI partitioning tools supports all modern storage technologies. Fedora's Anaconda base supports all, though, and is hence chosen as the back-end for this new tool. The application is only a few months old but is already looking nice and useful. Features like RAID and BTRFS support are being worked on. Vojtech Trefny is the other developer working with Vratislav on blivet-gui. Here's the announcement.

Xiaomi's Next OS Looks Strikingly Similar To iOS 181

stephendavion writes Looks like Chinese device maker, Xiaomi, is taking its "Apple of the East" tag too literally. First, their CEO brazenly copies Steve Jobs' signature look, sitting cross-legged on the floor. And now, Xiaomi's latest version of Android shamelessly rips off iOS 7. MIUI 6, which is Xiaomi's upcoming edition of Android for its latest phones and tablets, looks almost exactly like Apple's operating system for iPhones, iPads and the iPod Touch. It features the same bright color palette and a flat design. Heck, it even does away with Google's "app drawer" and puts all apps on your home screen. It's like the CEO handed iPhones to the design team and barked: "Here, copy this!"
