Ask Slashdot: What's a Good Tool To Detect Corrupted Files? 247

Volanin writes "Currently I use a triple boot system on my Macbook, including MacOS Lion, Windows 7, and Ubuntu Precise (on which I spend the great majority of my time). To share files between these systems, I have created a huge HFS+ home partition (the MacOS native format, which can also be read in Linux, and in Windows with Paragon HFS). But last week, while working on Ubuntu, my battery ran out and the computer suddenly powered off. When I powered it on again, the filesystem integrity was OK (after a scandisk by MacOS), but a lot of my files' contents were silently corrupted (and my last backup was from August...). Mostly, these files are JPGs, MP3s, and MPG/MOV videos, with a few PDFs scattered around. I want to get rid of the corrupted files, since they waste space uselessly, but the only way I have to check for corruption is opening them up one by one. Is there a good set of tools to verify the integrity by filetype, so I can detect (and delete) my bad files?"

Ubuntu 12.04 LTS Out; Unity Gets a Second Chance 543

An anonymous reader writes with this enthusiastic review of the latest from Canonical: "So how does Ubuntu Precise Pangolin (12.04) fare? I will say exceptionally well. Unity is not the same ugly duckling it was made out to be. In Ubuntu 12.04, it has transformed into a beautiful swan. As Ubuntu 12.04 is a long term release, the Ubuntu team has pulled all stops to make sure the user experience is positive. Ubuntu 12.04 aka Precise Pangolin is definitely worthy of running on your machine."

Code Name, Theming Update Announced For Ubuntu 12.10 285

benfrog writes "In a blog post, Mark Shuttleworth announced some changes for Ubuntu 12.10 (due in October), including the code name (Quantal Quetzal — no, really) and a theme update. He said, 'That will kick off with a project on typography to make sure we are expressing ourselves with crystal clarity – making the most of Ubuntu’s Light and Medium font weights for a start. And a project on iconography, with the University of Reading, to refine the look of apps and interfaces throughout the platform. It’s amazing how quaint the early releases of Ubuntu look compared to the current style. And we’re only just getting started! In our artistic explorations we want to embrace tessellation as an expression of the part-digital, part-organic nature of Ubuntu.' Some other more meaningful announcements include a focus on the cloud in the server version and the lack of a transition from Upstart to systemd."

HP To Certify Ubuntu 12.04 LTS For Its Proliant Servers 66

An anonymous reader writes with this dose of nice news (untranslated from the PR-ese) on the Linux-in-business front: "Mark Shuttleworth has announced at the OpenStack conference that Canonical has received a ringing endorsement from HP in the form of certification for Ubuntu 12.04 LTS on the ProLiant server systems. Responding to customer demand, HP has decided to officially support the popular flavor of Linux giving sysadmins another flexible software option to leverage their current and future hardware."

Ask Slashdot: Best Book For 11-Year-Old Who Wants To Teach Himself To Program? 525

New submitter waferthinmint asks "What is the best book for my son to use to teach himself to program? He wants to study on his own but everything seems to assume an instructor or a working theoretical knowledge. He's a bright kid but the right guide can make all the difference. Also, what language should he start with? When I was in HS, it was Basic or Pascal. Now, I guess, C? He has access to an Ubuntu box and an older MacBook Pro. Help me Slashdot; you're our only hope."

Kubuntu To Be Sponsored By Blue Systems, Rather Than Canonical 99

JRiddell writes "Kubuntu, the KDE flavour from Ubuntu, has found a new sponsor in Blue Systems. They will be providing more resources than were available by previous sponsor Canonical. The project will remain much the same: community led, KDE focused, Ubuntu flavour. With the new independence it can branch out into new markets such as a Kubuntu Active flavour for tablets."

Controlling GNOME 3 With Skeltrack 18

dartttt writes with an excerpt from Ubuntu Vibes: "Skeltrack is a Free Software (GPL3) library by Igalia for tracking the human skeleton joints from depth images. It is implemented with GLib and uses plain mathematics to detect the human skeleton and although it does not use any database, it was inspired by Andreas Baak's paper: "A Data-Driven Approach for Real-Time Full Body Pose Reconstruction from a Depth Camera" Skeltrack devs have recorded very cool videos showing Gnome Shell and Linux games being controlled through gestures."

GNU/Linux Running On An 8-Bit Processor 361

dartttt writes, quoting Ubuntu Vibe: "Dmitry Grinberg has successfully booted Ubuntu 9.04 on an 8 bit micro machine with 6.5 KHz CPU and 16 MB RAM. Grinberg did this experiment on a ATmega1284p, 8-bit RISC microcontroller clocked at 24MHz and equipped with 16KB of SRAM and 128KB of flash storage. Since the RAM was too low, he added 30-pin 16MB SIMM to the machine and a 1 GB SD card to host Ubuntu image. ... To get the world's slowest Linux Computer running, he had to write an ARMv5 emulator which supports a 32bit processor and MMU. A similar machine can be made very easily and everything should come in about $20." There is source code available, but it's under a non-commercial use only license. Just how slow is it? "It takes about 2 hours to boot to bash prompt ('init=/bin/bash' kernel command line). Then 4 more hours to boot up the entire Ubuntu ('exec init' and then login). Starting X takes a lot longer. The effective emulated CPU speed is about 6.5KHz, which is on par with what you'd expect emulating a 32-bit CPU & MMU on a measly 8-bit micro. Curiously enough, once booted, the system is somewhat usable. You can type a command and get a reply within a minute." If you like watching a whole lot of nothing, there's a video of the boot process below the fold.

Tom's Hardware Tests and Reviews Fedora 16 and Gnome 3 101

New submitter LordDCLXVI writes with a review at Tom's Hardware that starts out with some loaded questions about GNOME 3, as included in the newest version of Red Hat's Fedora: "While most other distros are passing up or postponing GNOME Shell, Fedora is full steam ahead. Does Red Hat know something the rest of us don't? Or is GNOME 3 really as bad as everyone says?" Writes LordDCLVXI: "This massive article amounts to a full-blown guide to Fedora 16 'Verne' and complete dissection of GNOME Shell. It begins with an installation guide, with instructions for enabling third-party repos, proprietary graphics drivers, Wi-Fi, Flash, Java, multimedia codecs, and 32-bit libs. Next up is a GNOME Shell tear-down, including customization options and methods to 'fix' the Shell or mimic GNOME 2. Finally, Fedora is benchmarked against Ubuntu 11.10 and Windows 7. [While the author] adds to the voices criticizing GNOME Shell, he also points out that the extensions can empower distributors to create unique, yet compatible layouts. One of the most fair and constructive critiques of GNOME 3 — definitely worth the read, and even makes GNOME 3 worth a second look."

Ask Slashdot: What Is the Best Distro For Linux Lessons? 319

MBtronics writes "I work at an embedded hardware/software company and we are currently moving all our products for Windows CE to Linux. Our core development team already uses their favorite distro for development, but the rest of the developers are still working on Windows. We are going to give a series of Linux lessons (from 'what is Linux' to installing, using and developing) for everybody in the company who is interested (including non-developers). They will be allowed to choose their own distro, but we will certainly get requests for recommendations. My question to the Slashdot crowd: what distro (and window manager) do you think is the best to teach Linux to the generic public? We are currently thinking of Ubuntu, Fedora or Mint."

Ubuntu 12.04 LTS Precise Pangolin Beta 1 Released 243

donadony writes with news about what will become the next LTS release of Ubuntu. From the article: "It's time to take another look at what is happening with the development of Ubuntu 12.04. As it stands, the first Beta of Ubuntu 12.04 LTS Precise Pangolin has been released. I just updated my own system. What changed since Alpha? Not much, really. In fact, there's really nothing groundbreaking or any new features added. Unity has been updated to version 5.4.0 which also sees the introduction of the new HUD feature. HUD still apparently has many outstanding bugs, but developers maintain that all bugs will be ironed out before Ubuntu 12.04 goes gold. Also added were recommendations to Ubuntu software center, and a new tool called 'privacy' and other small new features."

Video Stealthy Pen Test Unit Plugs Directly Into 110 VAC Socket (Video) Screenshot-sm 74

Pwnie Express is a cute name for this tiny (and easily hidden) group of Pen Test devices. Their website says, 'Our initial hardware offering, the Pwn Plug, is the first-to-market commercial penetration testing drop box platform. This low-cost plug-and-play device is designed for remote security testing of corporate facilities, including branch offices and retail locations. A security professional or service provider can ship this device to a corporate facility and conduct a security test over the Internet without travel expenses.' Hardware buffs will recognize this unit as a SheevaPlug, but the value-add is that it's preloaded with Ubuntu Linux and and a rich suite of intrusion/testing tools. The company's 'Founder and CEO and everything else' is Dave Porcello. The video is an interview with Dave, in which he shows off and demonstrates some Pwnie Express products.

Ask Slashdot: How Do You Install Ubuntu On 30 Laptops and Keep Them In Sync? 202

New submitter spadadot writes "I am setting up a new event in France (Open du Web), where between 15 and 30 laptops running Ubuntu Linux will be available. They came with Windows preinstalled and it must stay for other purposes. I'd like to take care of only one of them (resize the hard drive, install Ubuntu, add additional software and apply custom settings) and effortlessly replicate everything to the others including hard drive resizing (unattended installation). After replicating, what should I do if I need to install new software or change some settings without manually repeating the same task on each one of them? Should I look into FAI, iPXE, Clonezilla, OCS Inventory NG? Other configuration management software? I would also like to reset the laptops to the original environment after the event."

Canonical Puts Ubuntu On Android Smartphones 155

nk497 writes "Canonical has revealed Ubuntu running on a smartphone — but the open source developer hasn't squashed the full desktop onto a tiny screen. Instead, the Ubuntu for Android system runs both OSes side by side, picking which to surface depending on the form factor. When a device — in the demo, it was a Motorola Atrix — is being used as a smartphone, it uses Android. When it's docked into a laptop or desktop setup, the full version of Ubuntu is used. Files, apps and other functionality such as voice calls and texting are shared between the two — for example, if a text message is sent to the phone when it's docked, the SMS pops up in Ubuntu, while calls can be received or made from the desktop." ZDnet has pictures; ExtremeTech has a story, too, including some words from Canonical CEO Jane Silber.

Linux Of the Future May Be About Which Environment, Not Which Distribution 214

itwbennett writes "In its 2012 roadmap, the Mozilla Foundation highlights plans to create its own soup-to-nuts mobile platform, known as Boot to Gecko. With this move, the Mozilla Foundation 'is finally shaking off its dependence on browser revenues and treading where Google, with ChromeOS; Canonical, with Unity on Ubuntu; and (most recently) the Plasma community's Spark tablet have already started: the creation of standards-based platforms that rely on robust web applications (in varying degrees) more than native-run apps to provide the user experience,' writes blogger Brian Proffitt. 'I very much think that we are heading for a time when Linux flavors will be identified by environments, not distributions.'"

GNOME 3: Beauty To the Bone? 647

someWebGeek writes "According to the GNOME design crew, as reported by Allan over at As Far as I Know, GNOME 3 will represent a new approach to GNOME application design. The design patterns being developed and employed may effect a new, prettier interface, but more importantly a new mindset about the entire project, a mindset intended to encourage greater deep beauty in the application layers below the user interface. Maybe...for now, I'm sticking to the sinking ship of KDE in the Ubuntu ocean."

Ubuntu 12.04 To Include Head-Up Display Menus 449

For the first few years of its existence, it would have been fair to say that Canonical was essentially polishing, packaging and publishing Debian Linux (and Gnome) to create the base Ubuntu desktop, to great acclaim. For the past few years, though, the company has pushed new looks and new applications (cf. Unity and Ubuntu TV), and refused to stick with prettifying existing interfaces. Now, Barence writes with this excerpt from PC Pro: "Ubuntu is set to replace the 30-year-old computer menu system with a 'Head-Up Display' that allows users to simply type or speak menu commands. Instead of hunting through drop-down menus to find application commands, Ubuntu's Head-Up Display lets users type what they want to do into a search box. The system suggests possible commands as the user begins typing – entering 'Rad' would bring up the Radial blur command in the GIMP art package, for example. HUD also uses fuzzy matching and learns from past searches to ensure the correct commands are offered to users. Canonical's Mark Shuttleworth told PC Pro the HUD will make it easier for people to learn new software packages, and migrate from Windows to Linux software without having to relearn menus. The HUD will first appear in Ubuntu 12.04."
