40 Years of Multics, 1969-2009 138

gribll writes "October 2009 marked an important milestone in the history of computing. It was exactly 40 years since the first Multics computer system was used at MIT. The interview is with Multics co-developer, MIT Professor and Turing Award winner Fernando J. Corbato. Multics (Multiplexed Information and Computing Service) is regarded as the foundation of modern time-sharing systems. Multics was the catalyst for the development of Unix and has been used as a model of operating system design since its release four decades ago. There is also a picture gallery of Multics history."

Arbitrary Code Execution With "ldd" 184

pkrumins writes "The ldd utility is more vulnerable than you think. It's frequently used by programmers and system administrators to determine the dynamic library dependencies of executables. Sounds pretty innocent, right? Wrong! It turns out that running ldd on an executable can result in executing arbitrary code. This article details how such executable can be constructed and comes up with a social engineering scenario that may lead to system compromise. I researched this subject thoroughly and found that it's almost completely undocumented."

NVIDIA Driver Developer Discusses Linux Graphics 317

An anonymous reader writes "Andy Ritger, who leads the NVIDIA UNIX Graphics Team responsible for creating drivers on Linux, FreeBSD and Solaris, has answered many questions at Phoronix about the state of Linux graphics, gaming, and drivers. Ritger shares some interesting facts, such as: the Linux graphics driver download rate is 0.5% that of their Windows driver downloads at NVIDIA.com; how the Nouveau developers are doing an incredible job; creating an AMD-like open-source strategy at NVIDIA would be time intensive and unlikely; and development problems for the Linux platform. Also commented on are new features that may come to their Linux driver within the next twelve months." Like all stories at Phoronix, in common with most other hardware review sites, this one is arbitrarily and maddeningly spread across 8 pages.

Apple Blurs the Server Line With Mac Mini Server 557

Toe, The writes "Today Apple announced several new hardware offerings, including a new Mac mini, their (almost-literally) pint-sized desktop computer. In a bizarre twist, they are now also offering a Mac mini with Mac OS X Server bundled in, along with a two hard drives somehow stuffed into the tiny package. Undoubtedly, many in the IT community will scoff at the thought of calling such a device a 'server.' However, with the robust capabilities of Snow Leopard Server (a true, if highly GUI-fied, UNIX server), it seems likely to find a niche in small businesses and even enthusiasts' homes. The almost completely guided setup process means that people can set up relatively sophisticated services without the assistance of someone who actually knows what they are doing. What the results will be in terms of security, etc. will be... interesting to watch as they develop." El Reg has a good roundup article of the many announcements; the multi-touch Magic Mouse is right up there on the techno-lust-inspiration scale.

OpenSolaris vs. Linux, For Linux Users 303

An anonymous reader writes "With Sun busy being swallowed up by Oracle, should Linux geeks pay any interest to OpenSolaris? TuxRadar put together a guide to OpenSolaris's most interesting features from a Linux user's perspective, covering how to get started with ZFS and virtualisation alongside more consumer-friendly topics such as hardware and Flash support."

Meet Uzbl — a Web Browser With the Unix Philosophy 318

DigDuality writes "Dieter@be over at Arch Linux forums, a release engineer for Arch Linux, got inspired by this post. The idea? To create a browser based on the Unix philosophy: 'Write programs that do one thing and do it well, programs that work well together, programs to handle text streams because that is a universal interface,' among other points. The result? A fast, low-resource browser named Uzbl, based on WebKit, which passes the Acid3 Test with a perfect score. The browser is controlled (by default) by vim-like keybindings, not too dissimilar to vimperator for Firefox. Things like URL changing, loading/saving of bookmarks, saving history, and downloads are handled through external scripts that you write (though the Uzbl software does come with some nice scripts for you to use). It fits great in a tiling window manager and plays extremely well with dmenu. The learning curve is a bit steep, but once you get used to it, it's smooth sailing. Not bad for alpha software. Though built for Arch, it has been reported to work on Ubuntu."

Appeals Court Overturns 2007 Unix Copyright Decision 330

snydeq writes "A federal appeals court has overturned a 2007 decision that Novell owns the Unix code, clearing the way for SCO to pursue a $1 billion copyright infringement case against IBM. In a 54-page decision (PDF), the 10th Circuit Court of Appeals said it was reversing the 2007 summary judgment decision by Judge Dale Kimball of the US District Court for the District of Utah, which found that Novell was the owner of Unix and UnixWare copyrights. SCO CEO Darl McBride called the decision a 'huge validation for SCO.'" The case over who owns Unix will now go to trial in Utah.

Microsoft Acknowledges Linux Threat To Windows 348

angry tapir sends along coverage from Good Gear Guide of a recent Microsoft !0-K SEC filing: "Microsoft for the first time has named Linux distributors Red Hat and Canonical as competitors to its Windows client business in its annual filing to the US Securities and Exchange Commission. The move is an acknowledgment of the first viable competition from Linux to Microsoft's Windows client business, due mainly to the use of Linux on netbooks, which are rising in prominence as alternatives to full-sized notebooks. ... 'Client faces strong competition from well-established companies with differing approaches to the PC market,' Microsoft said in the filing. 'Competing commercial software products, including variants of Unix, are supplied by competitors such as Apple, Canonical, and Red Hat.'"

The Ethics of Selling GPLed Software For the iPhone 782

SeanCier writes "We're a small (two-person) iPhone app developer whose first game has recently been released in the App store. In the process, we've inadvertently stepped in it, bringing up a question of the GPL and free software ethics that I'm hoping the Slashdot community can help us clear up, one way or the other. XPilot, a unique and groundbreaking UNIX-based game from the early/mid nineties, was a classic in its day, but was forgotten and has been dead for years, both in terms of use and development. My college roommate and I were addicted to it at the time, even running game servers and publishing custom maps. As it's fully open source (GPLv2), and the iPhone has well over twice the graphics power of the SGI workstations we'd used in college, we decided it was a moral imperative to port it to our cellphones. In the process, we hoped, we could breathe life back into this forgotten classic (not to mention turning a years-old joke into reality). We did so, and the result was more playable than we'd hoped, despite the physical limitations of the phone. We priced it at $2.99 on the App store (we don't expect it to become the Next Big Thing, but hoped to recoup our costs — such as server charges and Apple's annual $99 developer fee), released the source on our web page, then enthusiastically tracked down every member of the original community we could find to let them know of the hoped-for renaissance. Which is where things got muddy. After it hit the App store, one of the original developers of XPilot told us he feels adamantly that we're betraying the spirit of the GPL by charging for it." Read on for the rest of Sean's question.

Linux Notebooks Selling Well On Amazon Germany 207

christian.einfeldt writes "The LinuxTech.net blog points out that Linux notebooks are currently selling quite well on Amazon's list in Germany. The blog includes screenshots showing the Linux Asus and Aspire notebooks in positions 2 and 4, respectively, on that list. These machines are not netbooks, but full notebooks, albeit on the moderate to low side regarding price and performance. That LinuxTech.net blog was dated 23 July 2009, and the Asus machine is still holding second place more than one day later, while the Acer machine slipped to fifth position, despite the volatile nature of Amazon bestseller lists. While these two data points are just snapshots in time, they are consistent with other data showing that Microsoft itself attributes some of its recent weak earnings to surging sales of low-end notebooks, as well as data showing that the Linux-powered and Unix-powered computers topped Amazon's sales charts in all categories for 2007. If there is to ever be a 'year of desktop (or laptop) Linux', it won't happen all at once, but will creep up in ways similar to what we are seeing now."

Firefox 3.5.1 Released 147

alek writes "A day after Slashdot reports about a self-inflicted vulnerability in Firefox 3.5, Mozilla releases 3.5.1. It addresses that security issue, but also fixes the annoying slow-startup on Windows. Bummer the UNIX wars have subsided, because apparently they also had to fix a problem where Firefox on a Sparc platform would crash when visiting www.hp.com!"

CJKV Information Processing 2nd ed. Screenshot-sm 52

stoolpigeon writes "At the end of last year, I made a move from an IT shop focused on supporting the US side of our business to a department that provides support to our operations outside the US. This was the first time I've worked in an international context and found myself, on a regular basis, running into long-time assumptions that were no longer true. My first project was implementing a third-party, web-based HR system for medium-sized offices. I found myself constantly missing important issues because I had such a narrow approach to the problem space. Sure, I've built applications and databases that supported Unicode, but I've never actually implemented anything with them but the same types of systems I'd built in the past with ASCII. But a large portion of the world's population is in Asia, and ASCII is certainly not going to cut it there. Fortunately, a new edition of Ken Lunde's classic CJKV Information Processing has become available, and it has really opened my eyes." Keep reading for the rest of JR's review.

Staying In Shape vs. a Busy IT Job Schedule? 865

tnok85 writes "I started a new job ~7 months ago at a very large company working a 12-hour night shift (7PM-7AM) in a fairly high volume NOC. Our responsibilities extend during the night to basically cover everything but the most complex situations regarding UNIX/Windows/Linux/App administration, at which point we'll reach out to the on-calls. I live 1.5 hours away as well, so it turns into 4-5 15 hour days a week of sitting still — throw in almost an hour to get ready to leave, and a bit of time after I get home to unwind and I'm out of time to work out. Unfortunately I'm pretty sure I have a very slow metabolism, ever since I was a pre-teen I would gain weight fairly quickly if I didn't actively work out, regardless of how much or what I eat. (Barring starving myself, I suppose...) So, how does somebody who works a minimum of 60 hours over 4 days, often adding another 12 another day, and sometimes working 7-10 days straight like this, stay in shape? I can't hold a workout schedule, (which every person I've talked to in my history says is necessary to stay in shape) and I can't 'wake up early' or 'work out before bed' because I need sleep. Any thoughts/opinions/suggestions?"

Predicting SCO's Actions Post Bankruptcy 102

eldavojohn writes "SCO lost last year and began the bankruptcy filings a long time ago but PJ has some speculative bad news on what they retain through the bankruptcy proceedings. SCO proposes to sell a number of assets to an outfit called UnXis, which PJ characterizes this way: 'It starts to hint that this is more a renaming, taking in some new management who seem to have financial expertise, and SCO keeps skipping along as unXis, with the dangerous litigation spun off safely into a litigation troll.' In their filings SCO says they retain 'their litigation and related claims against International Business Machines Corporation, Novell, Inc., AutoZone Corporation, Red Hat and certain Linux users which are not material customers of UnXis (excluding certain large-scale users of Linux servers) that are claimed to have infringed against UNIX copyrights.' So that's still a possibility they could go after anyone who is a 'certain Linux user.' And what's even worse is that they'll retain a patent for running multiple Java applications on a single Java virtual machine. We may not be out of the SCO litigation woods yet."

SCO Sells Its UNIX Product Line To London Firm 95

An anonymous reader writes "SCO just forged a deal to sell its UNIX product line to Gulf Capital Partners LLC of London. Under the terms of the deal, SCO would continue to exist as a separate company helmed by Darl McBride, with its primary remaining assets being related to its mobile platform offerings. However, it's noted that this deal must be approved by the court, and should not be considered 'done' yet. It could fall through as others have in the past."

Drupal 6: Ultimate Community Site Guide Screenshot-sm 63

Michael J. Ross writes "Among the more popular and better-regarded content management systems (CMSs), Drupal is distinguished partly by its building-block approach, in which a website's functionality is built up in pieces, each of which is a module (either core or contributed). The opposite approach — using far fewer but more encompassing modules — is generally preferred by non-developers who do not relish integrating a sizable collection of modules or trying to modify the underlying code. Nonetheless, anyone who wishes to build a Drupal-based social website, can learn how to do so in a new e-book titled Drupal 6: Ultimate Community Site Guide."

Saving Unix Heritage, One Kernel At a Time 169

coondoggie writes "In this, its 40th year of operating system life, some Unix stalwarts are trying to resurrect its past. That is, they are taking on the unenviable and difficult job of restoring to their former glory old Unix software artifacts such as early Unix kernels, compilers and other important historical source code pieces. In a paper to be presented at next week's Usenix show, Warren Toomey of the Bond School of IT is expected to detail restoration work being done on four key Unix software artifacts all from the early 1970s — Nsys, 1st edition Unix kernel, 1st and 2nd edition binaries and early C compilers. In his paper, Toomey states that while the history of Unix has been well-documented, there was a time when the actual artifacts of early Unix development were in danger of being lost forever."

Unix Turns 40 254

wandazulu writes "Forty years ago this summer, Ken Thompson sat down and wrote a small operating system that would eventually be called Unix. An article at ComputerWorld describes the history, present, and future of what could arguably be called the most important operating system of them all. 'Thompson and a colleague, Dennis Ritchie, had been feeling adrift since Bell Labs had withdrawn earlier in the year from a troubled project to develop a time-sharing system called Multics (Multiplexed Information and Computing Service). They had no desire to stick with any of the batch operating systems that predominated at the time, nor did they want to reinvent Multics, which they saw as grotesque and unwieldy. After batting around some ideas for a new system, Thompson wrote the first version of Unix, which the pair would continue to develop over the next several years with the help of colleagues Doug McIlroy, Joe Ossanna and Rudd Canaday.'"

SQL in a Nutshell Screenshot-sm 86

stoolpigeon writes "The cover of SQL in a Nutshell sports a chameleon, the little lizard well known for its ability to blend in just about anywhere. This is a great choice for the Structured Query Language. SQL has been around since the seventies, helping developers interact with the ubiquitous relational database management system. Thirty some years later, SQL grinds away in the background of just about any interactive web site and nameless other technologies. New alternatives are popping up constantly but I'm going to go out on a limb and say that SQL is going to be around for a long time. Anyone interacting with an RDBMS is in all likelihood going to need to use SQL at some point. For those who do, who also want a handy desktop reference, SQL in a Nutshell has been there for the last 9 years. The SQL language itself has not stood still over those years, and neither have the products that use SQL, and so now the book is available in a third edition." Read on for the rest of JR's review.
