What the GNOME Desktop Gets Right and KDE Gets Wrong 267

An anonymous reader writes: Eric Griffith at Phoronix has provided a fresh perspective on the KDE vs. GNOME desktop debate after exclusively using GNOME for the past week while being a longtime KDE user. He concluded his five-page editorial (which raises some valid points throughout) by saying, "Gnome feels like a product. It feels like a singular experience. When you use it, it feels like it is complete and that everything you need is at your fingertips. It feels like the Linux desktop. ... In KDE, it's just some random-looking window popup that any application could have created. ... KDE doesn't feel like cohesive experience. KDE doesn't feel like it has a direction its moving in, it doesn't feel like a full experience. KDE feels like its a bunch of pieces that are moving in a bunch of different directions, that just happen to have a shared toolkit beneath them." However, with the week over and despite his criticism, he's back to using KDE.

Speed-Ups, Small Fixes Earn Good Marks From Ars For Mint 17.2 69

Ars Technica reviews the newest release from Linux MInt -- version 17.2, offered with either the Cinnamon desktop, or the lighter-weight MATE, which feels like what Gnome 2 might feel in an alternate universe where Gnome 3 never happened. Reviewer Scott Gilbertson has mostly good things to say about either variety, and notes a few small drawbacks, too. The nits seem to be minor ones, though they might bite some people more than others: Mint, based on Ubuntu deep down, is almost perfectly compatible with Ubuntu packages, but not every one, and this newest version of Mint ships with the 3.16 kernel of Ubuntu 14.04, which means slightly less advanced hardware support. (Gilbertson notes, though, that going with 3.16 means Mint may be the ideal distro if you want to avoid systemd.) "This release sees the Cinnamon developers focusing on some of what are sometimes call "paper cut" fixes, which just means there's been a lot of attention to the details, particularly the small, but annoying problems. For example, this release adds a new panel applet called "inhibit" which temporarily bans all notifications. It also turns off screen locking and stops any auto dimming you have set up, making it a great tool for when you want to watch a video or play a game." More "paper cut" fixes include improved multi-panel options, graphics-refresh tweaks, a way to restart the Cinnamon desktop without killing the contents of a session, graphics-refresh tweaks, and other speed-ups that make this release "noticeably snappier than its predecessor on the same hardware."

Calculating the Truck-Factor of Popular Open Source Projects 79

An anonymous reader writes: The Truck Factor describes the minimal number of developers that have to be hit by a truck (or quit) before a project is incapacitated. Wikipedia defines it as a "measurement of the concentration of information in individual team members. A high truck factor means that many individuals know enough to carry on and the project could still succeed even in very adverse events." The term is also known by bus factor/number. In this article, the authors calculate the truck factor for 133 popular GitHub applications. Spoiler, but unsurprising: Linux ranks near the top (meaning that it's highly resilient).

Lenovo Will Sell Ubuntu Laptops In India 77

puddingebola notes the news, as carried by Tom's Hardware, that Lenovo will soon ship laptops preloaded with Ubuntu in India. "The first of these systems will be the Lenovo Thinkpad L450, featuring only one of two CPUs, but the selection may widen over time and expand to other countries ...Overall, switching to Ubuntu reduces the system cost considerably. Currently, the standard L450 system with Windows 8.1 Pro utilizing a Core i3, 4 GB of RAM, and a 500 GB HDD costs 59724 INR ($943.02 USD). An Ubuntu version of the system with the same hardware specs, however, will only cost 48000 INR ($757.91 USD).

Linux Foundation's Census Project Ranks Open Source Software At Risk 47

jones_supa writes: The Core Infrastructure Initiative, a Linux Foundation effort assembled in the wake of the Heartbleed fiasco to provide development support for key Internet protocols, has opened the doors on its Census Project — an effort to figure out what software projects need support now, instead of waiting for them to break. Census assembles metrics about open source projects found in Debian's package list and on openhub.net, and then scores them based on the amount of risk each presents. Risk scores are an aggregate of multiple factors: how many people are known to have contributed to the project in the last 12 months, how many CVEs have been filed for it, how widely used it is, and how much exposure it has to the network. According to the current iteration of the survey, the programs most in need of attention are not previously cited infrastructure projects, but common core Linux system utilities that have network access and little development activity around them.

Linux 4.2-rc1 Is One of the Largest Kernel Releases of Recent Times 110

An anonymous reader writes: Linus Torvalds ended the Linux 4.2 kernel merge window today by releasing Linux 4.2-rc1. He quickly wrote, "I thought this release would be one of the biggest ones ever, but it turns out that it will depend on how you count." By most metrics, Linux 4.2 is shaping up to be a very large release. Linux 4.2 is bringing plenty of new features including the new 'AMDGPU' kernel graphics driver, Intel Broxton support, NCQ TRIM improvements, F2FS file-system encryption, new ARM CPU/board support, Renesas R8/300 arch support, and many other additions.

How IKEA Patched Shellshock 154

jones_supa writes: Magnus Glantz, IT manager at IKEA, revealed that the Swedish furniture retailer has more than 3,500 Red Hat Enterprise Linux servers. With Shellshock, every single one of those servers needed to be patched to limit the risk of exploitation. So how did IKEA patch all those servers? Glantz showed a simple one-line Linux command and then jokingly walked away from the podium stating "That's it, thanks for coming." On a more serious note, he said that it took approximately two and half hours to upgrade their infrastructure to defend against Shellshock. The key was having a consistent approach to system management, which begins with a well-defined Standard Operating Environment (SOE). Additionally, Glantz has defined a lifecycle management plan that describes the lifecycle of how Linux will be used at Ikea for the next seven years.

Ask Slashdot: User-Friendly, Version-Preserving File Sharing For Linux? 212

petherfile writes: I've been a professional with Microsoft stuff for more than 10 years and I'm a bit sick of it to be honest. The one that's got me stuck is really not where I expected it to be. You can use a combination of DFS and VSS to create a file share where users can put whatever files they are working on that is both redundant and has "previous versions" of files they can recover. That is, users have a highly available network location where they can "go back" to how their file was an hour ago. How do you do that with Linux?

This is a highly desirable situation for users. I know there are nice document management things out there that make sharepoint look silly, but I just want a simple file share, not a document management utility. I've found versioning file systems for Linux that do what Microsoft does with VSS so much better (for having previous version of files available.) I've found distributed file systems for Linux that make DFS look like a bad joke. Unfortunately, they seem to be mutually exclusive. Is there something simple I have missed?

Interview: Ask Linus Torvalds a Question 383

samzenpus writes: Linus Torvalds, the man behind the development of the Linux kernel, needs no introduction to Slashdot readers. Recently, we talked about his opinion on C++, and he talked about the future of Linux when he's gone. It's been a while since we sat down with Linus to ask him questions, so he's agreed to do it again and answer any you may have. Ask as many questions as you'd like, but please keep them to one per post.

The Open Container Project and What It Means 54

An anonymous reader writes: Monday saw the announcement of the Open Container Project in San Francisco. It is a Linux Foundation project that will hold the specification and basic run-time software for using software containers. The list of folks signing up to support the effort contains the usual suspects, and this too is a good thing: Amazon Web Services, Apcera, Cisco, CoreOS, Docker, EMC, Fujitsu Limited, Goldman Sachs, Google, HP, Huawei, IBM, Intel, Joyent, the Linux Foundation, Mesosphere, Microsoft, Pivotal, Rancher Labs, Red Hat, and VMware. In this article Stephen R. Walli takes a look at what the project means for open source.

Ask Slashdot: Keeping Cloud Data Encrypted Without Cross-Platform Pain? 107

bromoseltzer writes: I use cloud storage to hold many gigs of personal files that I'd just as soon were not targets for casual data mining. (Google: I'm thinking of you.) I want to access them from Linux, Windows, and Android devices. I have been using encfs, which does the job for Linux fairly well (despite some well-known issues), but Windows and Android don't seem to have working clients. I really want to map a file system of encrypted files and encrypted names to a local unencrypted filesystem — the way encfs works. What solutions do Slashdot readers recommend? Ideal would be a competitive cloud storage service like Dropbox or Google Drive that provides trustworthy encryption with suitable clients. Is there anything like that?

Google Criticized For 'Opaque' Audio-Listening Binary In Debian Chromium 85

An anonymous reader writes: Google has fallen under criticism for including a compiled audio-monitoring binary in Chromium for Debian. A report was logged at Debian's bug register on Tuesday noting the presence of a non-auditable 'hotword' module in Chromium 43. The module facilitates Google's "OK, Google" functionality, which listens for that phrase via a Chrome user's microphone and attempts afterwards to interpret the user's instructions as a search query. Matt Giuca from the Chromium development team responded after the furore developed, disclaiming Google from any responsibility from auditing Chromium code, but promising clearer controls over the feature in release 45.

Reasons To Use Mono For Linux Development 355

Nerval's Lobster writes: In the eleven years since Mono first appeared, the Linux community has regarded it with suspicion. Because Mono is basically a free, open-source implementation of Microsoft's .NET framework, some developers feared that Microsoft would eventually launch a patent war that could harm many in the open-source community. But there are some good reasons for using Mono, developer David Bolton argues in a new blog posting. Chief among them is MonoDevelop, which he claims is an excellent IDE; it's cross-platform abilities; and its utility as a game-development platform. That might not ease everybody's concerns (and some people really don't like how Xamarin has basically commercialized Mono as an iOS/Android development platform), but it's maybe enough for some people to take another look at the platform.

TRIM and Linux: Tread Cautiously, and Keep Backups Handy 182

An anonymous reader writes: Algolia is a buzzword-compliant ("Hosted Search API that delivers instant and relevant results") start-up that uses a lot of open-source software (including various strains of Linux) and a lot of solid-state disk, and as such sometimes runs into problems with each of these. Their blog this week features a fascinating look at troubles that they faced with ext4 filesystems mysteriously flipping to read-only mode: not such a good thing for machines processing a search index, not just dishing it out. "The NGINX daemon serving all the HTTP(S) communication of our API was up and ready to serve the search queries but the indexing process crashed. Since the indexing process is guarded by supervise, crashing in a loop would have been understandable but a complete crash was not. As it turned out the filesystem was in a read-only mode. All right, let's assume it was a cosmic ray :) The filesystem got fixed, files were restored from another healthy server and everything looked fine again. The next day another server ended with filesystem in read-only, two hours after another one and then next hour another one. Something was going on. After restoring the filesystem and the files, it was time for serious analysis since this was not a one time thing.

The rest of the story explains how they isolated the problem and worked around it; it turns out that the culprit was TRIM, or rather TRIM's interaction with certain SSDs: "The system was issuing a TRIM to erase empty blocks, the command got misinterpreted by the drive and the controller erased blocks it was not supposed to. Therefore our files ended-up with 512 bytes of zeroes, files smaller than 512 bytes were completely zeroed. When we were lucky enough, the misbehaving TRIM hit the super-block of the filesystem and caused a corruption."

Since SSDs are becoming the norm outside the data center as well as within, some of the problems that their analysis exposed for one company probably would be good to test for elsewhere. One upshot: "As a result, we informed our server provider about the affected SSDs and they informed the manufacturer. Our new deployments were switched to different SSD drives and we don't recommend anyone to use any SSD that is anyhow mentioned in a bad way by the Linux kernel."
