NVIDIA Fixes Old Compiz Bug 47

Posted by timothy
from the mayan-long-count dept.
jones_supa writes NVIDIA has fixed a long-standing issue in the Ubuntu Unity desktop by patching Compiz. When opening the window of a new application, it would go black or become transparent on NVIDIA hardware. There have been bug reports dating back to Ubuntu 12.10 times. The problem was caused by Compiz, which had some leftover code from a port. An NVIDIA developer posted on Launchpad and said the NVIDIA team has been looking at this issue, and they also proposed a patch. "Our interpretation of the specification is that creating two GLX pixmaps pointing at the same drawable is not allowed, because it can lead to poorly defined behavior if the properties of both GLX drawables don't match. Our driver prevents this, but Compiz appears to try to do this," wrote NVIDIA's Arthur Huillet. The Compiz patch has been accepted upstream.

Microsoft's First Azure Hosted Service Is Powered By Linux 66

jones_supa (887896) writes "Canonical, through John Zannos, VP Cloud Alliances, has proudly announced that the first ever Microsoft Azure hosted service will be powered by Ubuntu Linux. This piece of news comes from the Strata + Hadoop World Conference, which takes place this week in California. The fact of the matter is that the news came from Microsoft who announced the preview of Azure HDInsight (an Apache Hadoop-based hosted service) on Ubuntu clusters yesterday at the said event. This is definitely great news for Canonical, as their operating system is getting recognized for being extremely reliable when handling Big Data. Ubuntu is now the leading cloud and scale-out Linux-based operating system."

Elementary OS: Why We Make You Type "$0" 208

Posted by samzenpus
from the drop-a-dollar-in-the-bucket dept.
jones_supa writes Open source software can always be acquired without charge, but can still incur significant development costs. Elementary OS wants to make people aware of this, and have changed their website to suggest donating when downloading, and make users explicitly enter "$0" if they want a free download. This is the same strategy Canonical has used when offering Ubuntu. The Elementary OS blog explains: "Developing software has a huge cost. Some companies offset that cost by charging hundreds of dollars for their software, making manufacturers pay them to license the software, or selling expensive hardware with the OS included. Others offset it by mining user data and charging companies to target ads to their users. [...] If we want to see the world of open source software grow, we should encourage users to pay for its development; otherwise it'll be underfunded or developers will have to resort to backdoor deals and advertising. And nobody wants that future." Currently the only people who have received money for working on Elementary OS have been community members through their bounty program.

Ask Slashdot: Is There a Web Development Linux Distro? 136

Posted by timothy
from the best-of-brood dept.
Qbertino writes I've been a linux user for more than 15 years now and in the last ten I've done basically all my non-trivial web development on Linux. SuSE in the early days, after that either Debian or, more recently, Ubuntu, if I want something to click on. What really bugs me is, that every time I make a new setup, either as a virtual machine, on concrete hardware or a remote host, I go through 1-2 hours of getting the basics of a web-centric system up and running. That includes setting PHP config options to usable things, setting up vhosts on Apache (always an adventure), configging mod_rewrite, installing extra CLI stuff like Emacs (yeah, I'm from that camp) walking through the basic 10-15 steps of setting up MySQL or some other DB, etc. ... You get the picture.

What has me wondering is this: Since Linux is deeply entrenched in the field of server-side web, with LAMP being it's powerhouse, I was wondering if there aren't any distros that cover exactly this sort of thing. You know, automatic allocation of memory in the runtime settings, ready-made Apache http/https/sftp/ftp setup, PHP all ready to go, etc. What are your experiences and is there something that covers this? Would you think there's a need for this sort of thing and would you base it of Debian or something else? If you do web-dev, how do you do it? Prepareted scripts for setup? Anything else? ... Ideas, unkown LAMP distros and opinions please."

The First Ubuntu Phone Is Here, With Underwhelming Hardware 177

Posted by timothy
from the early-days-yet dept.
A few days ago, Fast Company reviewer Jay Cassano was enthusiastic about Ubuntu's approach to apps for its new phone OS: namely, not relying on them, and instead interfacing seamlessly with existing websites and protocols. Now, new submitter ablutions (4006541) writes with a less than glowing review at The Daily Dot of the actual hardware that the OS is launching on. A sample that conveys the gist: Let's start with the good stuff: It sports a 4.5-inch multi-touch screen and a respectable 8-megapixel rear camera and 5-megapixel lens on the front. That's pretty much it. The list of negatives is a bit longer.

Why It's Important That the New Ubuntu Phone Won't Rely On Apps 140

Posted by Soulskill
from the they-hope dept.
tedlistens writes: To tackle the chicken-and-egg problem faced by the Windows Phone or Blackberry — you need an app ecosystem to gain market share, but you need market share in order to entice developers to your platform — Canonical, the creators of the free, open-source Linux-based OS Ubuntu, have taken a novel approach with their new phone, which will be launched in Europe next week: The phone — the Aquaris E4.5 Ubuntu Edition, made with Spanish manufacturers BQ — won't feature apps. Instead, it will have a new user experience paradigm called Scopes. These are "essentially contextual home-screen dashboards that will be much simpler and less time-consuming to develop than full-on native apps." For instance, the music Scope will pull songs from Grooveshark alongside music stored locally on your device, without strong differentiation between the two. The user experience, writes Jay Cassano at Fast Company, seems a lot more intuitive than the "app grids" that dominate most devices.

Dell Continues Shipping Fresh Linux Laptops 123

from the permanent-penguin dept.
jones_supa writes: In its latest move, Dell will be bringing Ubuntu 14.04 LTS to its top-of-the-line Precision M3800 workstation laptop and the latest model of the Dell XPS 13. Both systems will be running Ubuntu 14.04.1. According to Barton George, Dell's Director of Developer Programs, programmers had been asking for a better, officially-supported Ubuntu developer laptop. This came about from a combination of the efforts of Dell software engineer Jared Dominguez and enthusiastic feedback. Specs of M3800: 15.6" LCD @ 3840x2160, Intel i7 quad core CPU, NVIDIA Quadro GPU, up to 16 GB RAM. The bad news is, as Dominguez explained on his blog, this version of the M3800 doesn't support its built-in Thunderbolt 2 port out of the box. However, thanks to the hardware-enablement stack in Ubuntu, starting with upcoming Ubuntu 14.04.2, you will be able to upgrade your kernel to add some Thunderbolt support.

An anonymous reader writes Hacked has a piece about Georgia Institute of Technology researchers keylogging from a distance using the electromagnetic radiation of CPUs. They can reportedly do this from up to 6 meters away. In this video, using two Ubuntu laptops, they demonstrate that keystrokes are easily interpreted with the software they have developed. In their white paper they talk about the need for more research in this area so that hardware and software manufacturers will be able to develop more secure devices. For now, Faraday cages don't seem as crazy as they used to, or do they?

Canonical Launches Internet-of-Things Version of Ubuntu Core 43

from the things-need-love-too dept.
darthcamaro writes: Ubuntu Linux isn't just for desktops, servers and the cloud anymore. Mark Shuttleworth wants Ubuntu to be the operating system of choice for the Internet of Things too. The new Snappy Ubuntu Core is targeted at device developers and it's the basis for an entire new division of Canonical Inc. The promise of Snappy Ubuntu Core is also one of security, protecting the devices of the world, by keeping them updated. "With Snappy there is also a division of responsibilities for updating that can also help protect IoT devices and users. So we could deliver an update for a Heartbleed or Shellshock vulnerability, completely independently of the lawnmower control app that would come from the lawnmower company," Shuttleworth said.

Ask Slashdot: Linux Distro For Hybrid Laptop? 210

Posted by Soulskill
from the half-man-half-penguin dept.
Steve Parrish writes: I needed a new laptop and found a great deal on an Asus Transformer TP500L. It's one of the laptops where you can flip the screen back and use it as a tablet. I'd like to replace Windows 8.1, and I'm having a difficult time finding a Linux distro that will work on it. I'm familiar with Mint, SolydX, and older Ubuntu versions. I tried the latest Ubuntu with Unity and didn't like it, but the OS installed with only a few minor issues. Has anyone tried any other distros on a hybrid laptop with a touchscreen? I've used Linux for several years, but I'm no guru -- I'm not comfortable with the command line or other advanced workings. Any suggestions would be appreciated.

Docker Image Insecurity 73

Posted by Soulskill
from the totally-secure-for-undefined-values-of-secure dept.
An anonymous reader writes Developer Jonathan Rudenberg has discovered and pointed out a glaring security hole in Docker's system. He says, "Recently while downloading an 'official' container image with Docker I saw this line: ubuntu:14.04: The image you are pulling has been verified

I assumed this referenced Docker's heavily promoted image signing system and didn't investigate further at the time. Later, while researching the cryptographic digest system that Docker tries to secure images with, I had the opportunity to explore further. What I found was a total systemic failure of all logic related to image security.

Docker's report that a downloaded image is 'verified' is based solely on the presence of a signed manifest, and Docker never verifies the image checksum from the manifest. An attacker could provide any image alongside a signed manifest. This opens the door to a number of serious vulnerabilities."
Docker's lead security engineer has responded here.

$35 Quad-core Hacker SBC Offers Raspberry Pi-like Size and I/O 140

Posted by Soulskill
from the more-competition-more-innovation dept.
DeviceGuru writes: Hardkernel has again set its sights on the Raspberry Pi with a new $35 Odroid-C1 hacker board that matches the RPI's board size and offers a mostly similar 40-pin expansion connector. Unlike the previous $30 Odroid-W that used the same Broadcom BCM2835 SoC as the Pi and was soon cancelled due to lack of BCM2835 SoC availability, the Odroid-C1 is based on a quad-core 1.5GHz Cortex-A5 based Amlogic S805 SoC, which integrates the Mali-400 GPU found on Allwinner's popular SoCs. Touted advantages over the similarly priced Raspberry Pi Model B+ include a substantially more powerful processor, double the RAM, an extra USB2.0 port that adds Device/OTG, and GbE rather than 10/100 Ethernet.

Ubuntu Gets Container-Friendly "Snappy" Core 149

Posted by Soulskill
from the snappy-songbird?-corey-cormorant? dept.
judgecorp writes: Canonical just announced Ubuntu Core, which uses containers instead of packages. It's the biggest Ubuntu shakeup for 20 years, says Canonical's Mark Shuttleworth, and is based on a tiny core, which will run Docker and other container technology better, quicker and with greater security than other Linux distros. Delivered as alpha code today, it's going to become a supported product, designed to compete with both CoreOS and Red Hat Atomic, the two leading container-friendly Linux approaches. Shuttleworth says it came about because Canonical found it had solved the "cloud" problems (delivering and updating apps and keeping security) by accident — in its work on a mobile version of Ubuntu.

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.

OwnCloud Dev Requests Removal From Ubuntu Repos Over Security Holes 126

Posted by timothy
from the if-you-could-turn-back-time dept.
operator_error notes a report that ownCloud developer Lukas Reschke has emailed the Ubuntu Devel mailing list to request that ownCloud (server) be removed from the Ubuntu repositories because it contains "multiple critical security bugs for which no fixes have been backported," through which an attacker could "gain complete control [of] the web server process." From the article: However, packages can't be removed from the Ubuntu repositories for an Ubuntu version that was already released, that's why the package was removed from Ubuntu 14.10 (2 days before its release) but it's still available in the Ubuntu 14.04 and 12.04 repositories (ownCloud 6.0.1 for Ubuntu 14.04 and ownCloud 5.0.4 for Ubuntu 12.04, while the latest ownCloud version is 7.0.2). Furthermore, the ownCloud package is in the universe repository and software in this repository "WILL NOT receive any review or updates from the Ubuntu security team" (you should see this if you take a look at your /etc/apt/sources.list file) so it's up to someone from the Ubuntu community to step up and fix it. "If nobody does that, then it unfortunately stays the way it is", says Marc Deslauriers, Security Tech Lead at Canonical. You can follow the discussion @ Ubuntu Devel mailing list. So, until (if) someone fixes this, if you're using ownCloud from the Ubuntu repositories, you should either remove it or upgrade to the latest ownCloud from its official repository, hosted by the openSUSE Build Service."

Ubuntu 14.10 Released With Ambitious Name, But Small Changes 110

Posted by timothy
from the I'd-hoped-for-ubiquitous dept.
Ubuntu 14.10, dubbed Utopic Unicorn, has been released today (here are screenshots). PC World says that at first glance "isn't the most exciting update," with not so much as a new default wallpaper — but happily so: it's a stable update in a stable series, and most users will have no pressing need to update to the newest version. In the Ubuntu Next unstable series, though, there are big changes afoot: Along with Mir comes the next version of Ubuntu’s Unity desktop, Unity 8. Mir and the latest version of Unity are already used on Ubuntu Phone, so this is key for Ubuntu's goal of convergent computing — Ubuntu Phone and Ubuntu desktop will use the same display server and desktop shell. Ubuntu Phone is now stable and Ubuntu phones are arriving this year, so a lot of work has gone into this stuff recently. The road ahead looks bumpy however. Ubuntu needs to get graphics drivers supporting Mir properly. The task becomes more complicated when you consider that other Linux distributions — like Fedora — are switching to the Wayland display server instead of Mir. When Ubuntu Desktop Next becomes the standard desktop environment, the changes will be massive indeed. But for today, Utopic Unicorn is all about subtle improvements and slow, steady iteration.

Ubuntu Turns 10 110

Posted by timothy
from the ten-years-is-a-long-time dept.
Scott James Remnant, now Technical Lead on ChromeOS, was a Debian developer before that. That's how he became involved from the beginning (becoming Developer Manager, and then serving on the Technical Board) on the little derivative distribution that Mark Shuttleworth decided to make of Debian Unstable, and for which the name Ubuntu was eventually chosen. On this date in 2004, Ubuntu 4.10 -- aka Warty Warthog, or just Warty -- was released, and Remnant has shared a detailed, nostalgic look back at the early days of the project that has (whatever else you think of it ) become one of the most influential in the world of open source and Free software. I was excited that Canonical sent out disks that I could pass around to friends and family that looked acceptably polished to them in a way that Sharpie-marked Knoppix CD-ROMs didn't, and that the polish extended to the installer, the desktop, and the included constellation of software, too.

Now, the mobile operating system has finally reached "release to manufacturing" status. (Here's the release announcement.) The first phone running Ubuntu Touch, the Meizu MX4, will start shipping in December. "Details are scarce on its hardware, but a leak from iGeek suggests the Pro variant may have a Samsung Exynos 5430 processor, 4GB of RAM, and a 2560x1536 resolution screen. ... This more powerful hardware is good news if true, and it bodes well for Ubuntu's vision of computing convergence." Softpedia has a preview of the RTM version of the OS. They say performance has improved significantly, even on old phones, and that the UI has been polished into a much better state.

Ask Slashdot: Remote Support For Disconnected, Computer-Illiterate Relatives 334

Posted by samzenpus
from the help-me-please dept.
An anonymous reader writes I use email to communicate with my folks overseas. Their ISP only allows dial-up access to their email account (there is no option of changing ISP), that can receive messages no larger than 1MB nor hold more than 15MB (no hope of changing that either). They are computer-illiterate, click on everything they receive, and take delight on sending their information to any Nigerian prince that contacts them, "just in case this one is true". Needless to say, their PC is always full of viruses and spyware. In my next yearly visit, instead of just cleaning it up, I'd like to gift them with some "hardened" PC to use for email only that would hopefully last the year before someone has to fix it. So far, these are the things I have in mind:
  • Some kind of linux distro, or maybe even mac. Most viruses over there are windows only and propagate via Autorun.inf or by email attachments, not having Windows could prevent both.
  • Some desktop environment that hides anything unrelated to connecting to the net and accessing their account (dial-up software, email client, web browser, exchanging files between their hard disk/email attachments and USB drives). By "hide", I just want the rest to be out of the way, but not entirely removed, so that if necessary, I can guide them over the phone. For this, Ubuntu's Unity seems like a particularly bad solution, but a Gnome desktop with non-removable desktop shortcuts (is this possible?) for the file manager, browser, email client and dial-up program could work. An android system is unlikely to work (they have no wifi, and they were utterly confused with Android's UI).
  • This could be a life saver: some kind of extension to the email client that executes commands on specially formatted emails (e.g., signed with my private key), so that I can do some basic diagnostics or install extra software if I have to. This las point is important: they currently rely on acquaintances who may not be competent (they can't evaluate that) if something happens between my visits. They, most likely, wont know how to deal with anything non-windows, so all tech support would fall on me. (This is the reason I haven't moved them from windows yet.)
  • Another very useful extension would be something to automatically re-assemble attachments split into several emails, to overcome the 1MB message limit.

Does any of that exist? If I have to build that system myself (or parts of it), do you have other suggestions? For the inevitable and completely reasonable suggestion of getting someone competent for tech support: I've tried that too. The competent ones don't last beyond the third visit.
