Ask Slashdot: Which Classic OOP Compiled Language: Objective-C Or C++? 85

Posted by Soulskill
from the not-as-classic-as-COBOL dept.
Qbertino writes: I've been trying to pick up a classic, object-oriented, compiled language since the early 90s, but have never gotten around to it. C++ was always on my radar, but I'm a little torn to-and-fro with Objective-C. Objective-C is the obvious choice if you also want to make money developing for Mac OS X, but for the stuff I want to do, both languages would suffice on all platforms. I do want to start out on x86 Linux, though, and also use it as my main development platform. Yes, I know quite a few other languages, but I want to get into a widespread compiled language that has good ties into FOSS. Both Objective-C and C++ fit that bill. What do you recommend? How do these two programming languages compare with each other, and how easy is cross-platform development in either? (Primarily GUI-free, "headless" applications.)

Xfce 4.12 Released 88

from the onward-and-upward dept.
motang writes: After two years of hard work (and much to the dismay of naysayers who worried the project has been abandoned), the Xfce team has announced the release of Xfce 4.12. Highlights include improvements to the window switcher dialog, intelligent hiding of the panel, new wallpaper settings, better multi-monitor support, improved power settings, additions to the file manager, and a revamped task manager. Here is a quick tour, the full changelog, and the download page. I have been running it since Xubuntu 15.04 beta 1 was released two days ago. It is much improved over 4.10, and the new additions are great.

Users Decry New Icon Look In Windows 10 506

Posted by samzenpus
from the no-sir-I-don't-like-it dept.
jones_supa writes A lot of people got upset about the flat looks of Modern UI presented in Windows 8. Recent builds of Windows 10 Technical Preview have now started replacing the shell icons, and to some people they are just too much to bear. Basically, Microsoft opted to change the icons in search of a fresh and modern look, but there are plenty of people out there who claim that all these new icons are actually very ugly and the company would better stick to the previous design. To find out what people think about these icons, Softpedia asked its readers to tell their opinion and the messages received in the last couple of days pretty much speak for themselves. There are only few testers who think that these icons look good, but the majority wants Microsoft to change them before the final version of the operating system comes out.

Developers Disclose Schematics For 50-1000 MHz Software-Defined Transceiver 131

Posted by samzenpus
from the fire-up-the-boat-anchor dept.
Bruce Perens writes Chris Testa KD2BMH and I have been working for years on a software-defined transceiver that would be FCC-legal and could communicate using essentially any mode and protocol up to 1 MHz wide on frequencies between 50 and 1000 MHz. It's been discussed here before, most recently when Chris taught gate-array programming in Python. We are about to submit the third generation of the design for PCB fabrication, and hope that this version will be salable as a "developer board" and later as a packaged walkie-talkie, mobile, and base station. This radio is unique in that it uses your smartphone for the GUI, uses apps to provide communication modes, contains an on-board FLASH-based gate-array and a ucLinux system. We intend to go for FSF "Respects Your Freedom" certification for the device. My slide show contains 20 pages of schematics and is full of ham jargon ("HT" means "handi-talkie", an old Motorola product name and the hams word for "walkie talkie") but many non-hams should be able to parse it with some help from search engines.

Tim O'Reilly On Big Data, CS Education, and the Future of Print 26

Posted by Soulskill
from the timbits-of-wisdom dept.
M-Saunders writes: How do we take advantage of big data without putting our privacy at risk? Should everyone be able to code? And how much life is still in the market for printed books and publications? Linux Voice put these questions to Tim O'Reilly, the founder of O'Reilly media, and the man who helped to popularize the terms Open Source and Web 2.0. ("Should everybody be a professional coder? No way. Should everybody be able to do more than just use a GUI? Absolutely. Should people be able to automate operations of a computer? Absolutely.") Despite the amount of "free" (or advert-supported) content out there, O'Reilly still believes there's plenty of money to be made: "I think that the willingness of people to pay for things that delight them will not go away."

Removing Libsystemd0 From a Live-running Debian System 755

Posted by samzenpus
from the taking-sides dept.
lkcl writes The introduction of systemd has unilaterally created a polarization of the GNU/Linux community that is remarkably similar to the monopolistic power position wielded by Microsoft in the late 1990s. Choices were stark: use Windows (with SMB/CIFS Services), or use UNIX (with NFS and NIS). Only the introduction of fully-compatible reverse-engineered NT Domains services corrected the situation. Instructions on how to remove systemd include dire warnings that "all dependent packages will be removed", rendering a normal Debian Desktop system flat-out impossible to achieve. It was therefore necessary to demonstrate that it is actually possible to run a Debian Desktop GUI system (albeit an unusual one: fvwm) with libsystemd0 removed. The reason for doing so: it doesn't matter how good systemd is believed to be or in fact actually is: the reason for removing it is, apart from the alarm at how extensive systemd is becoming (including interfering with firewall rules), it's the way that it's been introduced in a blatantly cavalier fashion as a polarized all-or-nothing option, forcing people to consider abandoning the GNU/Linux of their choice and to seriously consider using FreeBSD or any other distro that properly respects the Software Freedom principle of the right to choose what software to run. We aren't all "good at coding", or paid to work on Software Libre: that means that those people who are need to be much more responsible, and to start — finally — to listen to what people are saying. Developing a thick skin is a good way to abdicate responsibility and, as a result, place people into untenable positions.

Xfce Getting a New Version Soon 193

Posted by timothy
from the welcome-eye-candy dept.
jones_supa writes It looks like the release of Xfce 4.12 is finally about to materialize. It has been about two and half years since the last stable release. There is now a concerted effort underway to ship a new release of this lightweight GTK+2 desktop environment out around the end of February or early March. "As we have discussed the status and progress of core components with many of you individually, we feel confident that the state of Xfce is good enough to polish some final edges and push more translations until then," wrote Simon Steinbeiß on the xfce4-dev mailing list. The official list of showstopper bugs does not look too bad either. However, looking at the long time between releases certainly makes one think if the project could have use for some extra resources.

How, and Why, Apple Overtook Microsoft 458

Posted by timothy
from the paper-beats-rock dept. writes James B. Stewart writes in the NYT that in 1998 Bill Gates said in an interview that he "couldn't imagine a situation in which Apple would ever be bigger and more profitable than Microsoft" but less than two decades later, Apple, with a market capitalization more than double Microsoft's, has won. The most successful companies need a vision, and both Apple and Microsoft have one. But according to Stewart, Apple's vision was more radical and, as it turns out, more farsighted. Where Microsoft foresaw a computer on every person's desk, Apple went a big step further: Its vision was a computer in every pocket. "Apple has been very visionary in creating and expanding significant new consumer electronics categories," says Toni Sacconaghi. "Unique, disruptive innovation is really hard to do. Doing it multiple times, as Apple has, is extremely difficult." According to Jobs' biographer Walter Isaacson, Microsoft seemed to have the better business for a long time. "But in the end, it didn't create products of ethereal beauty. Steve believed you had to control every brush stroke from beginning to end. Not because he was a control freak, but because he had a passion for perfection." Can Apple continue to live by Jobs's disruptive creed now that the company is as successful as Microsoft once was? According to Robert Cihra it was one thing for Apple to cannibalize its iPod or Mac businesses, but quite another to risk its iPhone juggernaut. "The question investors have is, what's the next iPhone? There's no obvious answer. It's almost impossible to think of anything that will create a $140 billion business out of nothing."

Windows 10: Charms Bar Removed, No Start Screen For Desktops 378

Posted by samzenpus
from the check-it-out dept.
jones_supa writes Late last week, Microsoft pushed out a new build (9926) of Windows 10 to those of you who are running the Technical Preview. The latest version comes with many new features, some easily accessible, others bubbling under, but two big changes are now certain: the Charms bar is dead, and Start Screen for large devices is no more. Replacing the Charms bar is the Action Center, which has many of the same shortcuts as the Charms bar, but also has a plethora of other information too. Notifications are now bundled into the Action Center and the shortcuts to individual settings are still easily accessible from this window. The Start Screen is no longer present for desktop users, the options for opening it are gone. Continuum is the future, and it has taken over what the Start Screen initiated with Windows 8.

Surface RT Devices Won't Get Windows 10 158

Posted by Soulskill
from the take-that-early-adopters dept.
whoever57 writes: In its announcement of Windows 10, Microsoft indicated not all devices would get the updated operating system. Now, Microsoft says its Surface devices running Windows RT won't be receiving full updates, though it does plan to roll some new functionality into them. "Given that Windows RT and RT 8.1 were designed for power economizing devices sporting 32-bit ARM architecture, and never had the same functionality — to many users' frustration — as full-blown Windows 8 and 8.1, it comes as little surprise that the RT versions of the operating system should be left out of the latest update loop. In fact, a week before Microsoft's big Windows 10 reveal on January 21, the company released firmware updates for all three models of its Intel-powered Surface Pro series, but neither of the ARM-based Surface tablets — the Surface 2 or Surface RT — received any new updates this month." The Surface Pro line of tablets, which run a normal version of Windows, will be getting an update to Windows 10.

Justified: Visual Basic Over Python For an Intro To Programming 648

Posted by timothy
from the I-know-let's-centralize-such-decisions dept.
theodp writes ICT/Computing teacher Ben Gristwood justifies his choice of Visual Basic as a programming language (as a gateway to other languages), sharing an email he sent to a parent who suggested VB was not as 'useful' as Python. "I understand the popularity at the moment of the Python," Gristwood wrote, "however this language is also based on the C language. When it comes to more complex constructs Python cannot do them and I would be forced to rely on C (which is incredibly complex for a junior developer) VB acts as the transition between the two and introduces the concepts without the difficult conventions required. Students in Python are not required to do things such as declare variables, which is something that is required for GCSE and A-Level exams." Since AP Computer Science debuted in 1984, it has transitioned from Pascal to C++ to Java. For the new AP Computer Science Principles course, which will debut in 2016, the College Board is leaving the choice of programming language(s) up to the teachers. So, if it was your call, what would be your choice for the Best Programming Language for High School?

Why Run Linux On Macs? 592

Posted by timothy
from the horses-for-courses dept.
jones_supa writes Apple has always had attractive and stylish hardware, but there are always some customers opting to run Linux instead of OS X on their Macs. But why? One might think that a polished commercial desktop offering designed for that specific lineup of computers might have less rough edges than a free open source one. Actually there's plenty of motivations to choose otherwise. A redditor asked about this trend and got some very interesting answers. What are your reasons?

Ask Slashdot: Linux Database GUI Application Development? 264

Posted by timothy
from the now-make-yours-look-like-mine dept.
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

Posted by timothy
from the developing-tools dept.
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

Posted by Soulskill
from the helps-to-feed-your-developers dept.
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

Posted by timothy
from the don't-knock-interesting-hobbies dept.
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

Posted by timothy
from the context-sensitive dept.
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

from the upgrades-always-welcome dept.
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

Posted by timothy
from the point-fifth-world-problems dept.
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

Posted by timothy
from the gears-spinning dept.
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.
