Review: Make: Raspberry Pi Starter Kit 74

XWWT writes "A few weeks ago Make offered to send us a sample of its Raspberry Pi Starter Kit to see if we would do a review of the product. Samzenpus asked around the engineering team to see if there was someone who would be willing to do an on-camera review of the device. With all of the buzz about Raspberry Pi, I was very excited to get hands-on time with the device so I could more closely examine the platform. At first we wanted to do this piece as a video but quickly realized that a) it would probably be boring to see some blinky lights and push buttons working on a sample project, and b) the amount of audio that would need to be bleeped to cover my frustration with parts of the kit would be annoying. On a personal note, I also wanted to document all of my experience here as I thought it would be beneficial for newcomers to the maker technology and sometimes having someone else’s experience documented can help you avoid pitfalls and mistakes. (Full Disclosure: I am the Director of Engineering for Slashdot Media. We were given a review copy of the Make: Raspberry Pi Starter Kit. We were not paid for this review but had fun doing it.)"

Solaris Machine Shut Down After 3737 Days of Uptime Screenshot-sm 409

An anonymous reader writes "After running uninterrupted for 3737 days, this humble Sun 280R server running Solaris 9 was shut down. At the time of making the video it was idle, the last service it had was removed sometime last year. A tribute video was made with some feelings about Sun, Solaris, the walk to the data center and freeing a machine from internet-slavery."

Ask Slashdot: How Many Time Standards Are There? 214

jjoelc writes "Being one of those 'suffering' through the time change last night, the optimist in me reminded me that it could be much worse. That's when I started wondering how many different time/date standards there really are. Wikipedia is a good starting point, but is sorely lacking in the various formats used by e.g. Unix, Windows, TRS-80, etc. And that is without even getting into the various calendars that have been in and out of use throughout the ages. So how about it? How many different time/date 'standards' can we come up with? I'm betting there are more than a few horror stories of having to translate between them..."

KDE Releases Plasmate 1.0, A Plasma Workspaces SDK 16

jrepin writes "The KDE Plasma Workspaces team is excited to announce the first stable release of Plasmate: an add-ons SDK that focuses on ease of use. Plasmate follows the UNIX philosophy of "do one thing, and do it well". As such, it is not a general purpose IDE but rather a tool specifically tailored to creating Plasma Workspace add-ons using non-compiled languages such as QML and Javascript. It guides each step in the process, simplifying and speeding up project creation, development, adding new assets, testing and publishing. The goal of Plasmate is to enable creating something new in seconds and publishing it immediately."

The Book of GIMP Screenshot-sm 197

Michael Ross writes "Web designers, graphics artists, and others who create and edit digital images, have a number of commercial image-manipulation packages from which they can choose — such as Adobe Photoshop and Adobe Fireworks (originally developed by Macromedia). Yet there are also many alternatives in the open-source world, the most well-known being GNU Image Manipulation Program. GIMP is available for all major operating systems, and supports all commonly-used image formats. This powerful application is loaded with features, including plug-ins and scripting. Yet detractors criticize it as being complicated (as if Photoshop is intuitively obvious). Admittedly, anyone hoping to learn it could benefit from a comprehensive guide, such as The Book of GIMP."

Tim O'Reilly Steps In To Debate Open Government and Linux 45

PatrickRIot writes "Aeon Magazine ran a longform critique of Open Source politics last week titled 'Open Sesame: "Openness" is the new magic word in politics – but should governments really be run like Wikipedia?' It referenced Tim O'Reilly and the man himself has stepped in at the bottom of the page for a detailed and lengthy rejoinder. 'I'm a bit surprised to learn that my ideas of "government as a platform" are descended from Eric Raymond's ideas about Linux, since: a) Eric is a noted libertarian with disdain for government b) Eric's focus on Linux was on its software development methodology. From the start, I was the open source activist focused on the power of platforms, arguing the role for the architecture of Unix and the Internet in powering the open source movement. ... One thing that distresses me about this discussion is the notion that somehow, if open government doesn't solve every problem, or creates new problems as it solves others, it is a failed movement. The world doesn't go forward in a straight line! The "open" democracy experiment of 1776 is still ongoing; we're trying to figure out how to use technology to adapt it to the 21st century and a country with a hundredfold greater population.'"

DARPA Open Source Security Helped FreeBSD, Junos, Mac OS X, iOS 22

An anonymous reader writes "In a February 2013 ACM Queue / Communications of the ACM article, A decade of OS access-control extensibility, Robert Watson at the University of Cambridge credits 2000s-era DARPA security research, distributed via FreeBSD, for the success of sandboxing in desktop, mobile, and embedded systems such as Mac OS X, iOS, and Juniper's Junos router OS. His blog post about the article argues that OS security extensibility is just as important as more traditional file system (VFS) and device driver extensibility features in kernels — especially in embedded environments where UNIX multi-user security makes little sense, and where tradeoffs between performance, power use, functionality, and security are very different. This seems to fly in the face of NSA's recent argument argument that one-size-fits-all SELinux-style Type Enforcement is the solution for Android security problems. He also suggests that military and academic security researchers overlooked the importance of app-store style security models, in which signed application identity is just as important as 'end users' in access control."

You've Got 25 Years Until UNIX Time Overflows 492

CowboyRobot writes "In 25 years, an odd thing will happen to some of the no doubt very large number of computing devices in our world: an old, well-known and well-understood bug will cause their calculation of time to fail. The problem springs from the use of a 32-bit signed integer to store a time value, as a number of seconds since 00:00:00 UTC on Thursday, 1 January 1970, a practice begun in early UNIX systems with the standard C library data structure time_t. On January 19, 2038, at 03:14:08 UTC that integer will overflow. It's not difficult to come up with cases where the problem could be real today. Imagine a mortgage amortization program projecting payments out into the future for a 30-year mortgage. Or imagine those phony programs politicians use to project government expenditures, or demographic software, and so on. It's too early for panic, but those of us in the early parts of their careers will be the ones who have to deal with the problem."

Video A Chat With USENIX Community Manager Rikki Endsley (Video) Screenshot-sm 40

Rikki Endsley has been Community Manager for USENIX since September, 2011. She also edits their magazine, ;login:, writes for publications ranging from Linux.com to Network World, and is a long-distance runner to boot. But this interview concentrates on USENIX, a worthy organization that does a great job of helping its members (and the entire Unix/Linux community) stay up to date technically and, with its job board, keep USENIX members employed. Toward the end of the conversation, Rikki mentions some of the intangible but valuable benefits people get when they attend USENIX events.

New Releases From FreeBSD and NetBSD 149

tearmeapart writes "The teams at FreeBSD have reached another great achievement with FreeBSD 9.1, with improvements to the already fantastic zfs features, more VM improvements (helping bringing FreeBSD to the next generation of VMs), and improvements in speed to many parts of the network system. Support FreeBSD via the FreeBSD mall or download/upgrade FreeBSD from a mirror. Unfortunately, the torrent server is still down due to the previous security incident." And new submitter northar writes "The other day the NetBSD project released their first update to the 6.x series, 6.0.1. They also (rather discreetly) announced a fund drive targeting 60.000 USD before the end of 2012 in the release notes. They better get going if their donation page is anything like recently updated."

Researchers Convert Phones Into Secret Listening Devices 59

CowboyRobot writes "Columbia University grad student Ang Cui demonstrated how networked printers and phones can be abused by attackers. 'The attack I demonstrated is caused by the multiple vulnerabilities within the syscall interface of the CNU [Cisco Native Unix] kernel,' Cui tells Dark Reading. 'It is caused by the lack of input validation at the syscall interface, which allows arbitrary modification of kernel memory from userland, as well as arbitrary code execution within the kernel. This, in turn, allows the attacker to become root, gain control over the DSP [Digital Signal Processor], buttons, and LEDs on the phone. The attack I demonstrated patches the existing kernel and DSP in order to carry out stealthy mic exfiltration.'"

FreeBSD Project Falls Short of Year End Funding Target By Nearly 50% 245

TrueSatan writes "Perhaps a sign of our troubled times or a sign that FreeBSD is becoming less relevant to modern computing needs: the FreeBSD project has sought $500,000 by year end to allow it to continue to offer to fund and manage projects, sponsor FreeBSD events, Developer Summits and provide travel grants to FreeBSD developers. But with the end of this year fast approaching, it has raised just over $280,000, far short of its target."

FreeBSD Project Discloses Security Breach Via Stolen SSH Key 86

An anonymous reader writes "Following recent compromises of the Linux kernel.org and Sourceforge, the FreeBSD Project is now reporting that several machines have been broken into. After a brief outage, ftp.FreeBSD.org and other services appear to be back. The project announcement states that some deprecated services (e.g., cvsup) may be removed rather than restored. Users are advised to check for packages downloaded between certain dates and replace them, although not because known trojans have been found, but rather because the project has not yet been able to confirm that they could not exist. Apparently initial access was via a stolen SSH key, but fortunately the project's clusters were partitioned so that the effects were limited. The announcement contains more detailed information — and we are left wondering, would proprietary companies that get broken into so forthcoming? Should they be?"

Ask Slashdot: Finding Work Over 60? 306

First time accepted submitter Hatfield56 writes "I've been in IT since the mid-1980s, mainly working for financial institutions. After 16 years at a company, as a programmer (Java, C#, PL/SQL, some Unix scripting) and technical lead, my job was outsourced. That was in 2009 when the job market was basically dead. After many false starts, here I am 3 years later wondering what to do. I'm sure if I were 40 I'd be working already but over 60 you might as well be dead. SO, I'm wondering about A+. Does anyone think that this will make me more employable? Or should I being a greeter at Walmart?"

Ask Slashdot: Finding Legacy UnixWare Installation Media? 193

First time accepted submitter lukpac writes "We have an old (ancient) Unisys server in production that hosts a legacy system and are attempting to virtualize it. Unfortunately we don't have a generic UnixWare (2.1.2) installation CD, just a Unisys-specific one, and given the recent unpleasantness (see Groklaw for details), SCO isn't much of an option. We're not looking at pirating it (as above, we do still have the Unisys-specific media), but do need a generic copy of UnixWare. What options, if any, are available?"
