theodp writes "Think outside the box? Nah, think outside the bun. Ted Dziuba argues there's a programming lesson to be learned from observing how Taco Bell manages to pull down $1.9 billion by mixing-and-matching roughly eight ingredients: 'The more I write code and design systems, the more I understand that many times, you can achieve the desired functionality simply with clever reconfigurations of the basic Unix tool set. After all, functionality is an asset, but code is a liability. This is the opposite of a trend of nonsense called DevOps, where system administrators start writing unit tests and other things to help the developers warm up to them — Taco Bell Programming is about developers knowing enough about Ops (and Unix in general) so that they don't overthink things, and arrive at simple, scalable solutions.'"

Kurofuneparry writes "Apple has announced that Java is deprecated as of the most recent update to OS X. This shot across the bow is getting some responses. To Jobs' claim that 'Sun (now Oracle) supplies Java for all other platforms,' James Gosling is quoted as saying that 'simply isn't true.' Much talk of a coming turf war is to be had. This certainly can't be unrelated to statements from Jobs recently covered on this website and is sure to make waves. Apple has enjoyed significant success recently accompanied by a widespread sense that they can do no wrong in business or design. However, is deprecating Java a mistake? It doesn't take much insight to connect the dots and see that Apple has starting marking friends and enemies relative to the increasingly heated fight for mobile and other platforms."

theodp writes "With its forthcoming Lion Mac OS and new Apple-curated Mac Apps Store, Apple will be locking down top tier applications on the Mac similar to the way apps are locked down on the iPad and iPhone. Only by submitting their apps to Apple's store and giving up 30% of their receipts will developers get to take advantage of two new OS features. The first is Apple's new 'Launchpad,' a tool for easily opening application; the second is the ability to update apps to new versions with one click. It will be a lot easier to use apps bought from the Mac App Store than ones downloaded in the wild. It didn't have to be that way, says Valleywag's Ryan Tate: 'Apple could have enabled its Launchpad and auto-update features for all applications, sold through the Apple Store or not. For example, an open system for updating applications has been in use for years on Ubuntu... Ubuntu's 'Apt' (Advanced Packaging Tool) lets users install, update, and remove software of their choosing with a single command. There's a central list of apps curated by Ubuntu's maintainers, but users are free to add and install from other lists... But Apple seems to have made a very clear choice not to take the open route.' Longtime Apple developer Dave Winer was also concerned, tweeting during Apple's presentation 'Is this the end of the Mac as an open platform?' The news also prompted developer Anil Dash to call for an open alternative to the Mac App Store."

Esther Schindler writes "In 1986, Susan Lammers did a series of interviews with 19 prominent programmers in a Microsoft Press book, Programmers at Work. These interviews give a unique view into the shared perceptions of accomplished programmers, the people who invented the tools you use today. In Programmers Who Defined The Technology Industry: Where Are They Now?, I tracked down the fate of these prominent developers — from Robert Carr (Framework) to Dan Bricklin (VisiCalc) to Toru Iwatani (author of Pac Man, I'm glad you asked). The article quotes the developers' 1986 views on programming, the business, and the future of computing. In two cases (Bricklin and Jonathan Sachs, author of Lotus 1-2-3) I spoke with them to learn if, and how, their views had changed. One meaty example: In 1986, Bill Gates said, on Microsoft's future: 'Even though there'll be more and more machines, our present thinking is that we won't have to increase the size of our development groups, because we'll simply be making programs that sell in larger quantities. We can get a very large amount of software revenue and still keep the company not dramatically larger than what we have today. That means we can know everybody and talk and share tools and maintain a high level of quality.' At the time, Microsoft had 160 programmers."

eldavojohn writes "A new paper (PDF) out of Carnegie Mellon University shows how to solve symmetric diagonally dominant linear systems much faster than before. The technique employs graph theory, randomized algorithms, and linear algebra to achieve an astonishing advantage over current methods to solve such systems. From the article: 'The result is a significant decrease in computer run times. The Gaussian elimination algorithm runs in time proportional to s^3, where s is the size of the SDD system as measured by the number of terms in the system, even when s is not much bigger the number of variables. The new algorithm, by comparison, has a run time of s*[log(s)]^2. That means, if s = 1 million, that the new algorithm run time would be about a billion times faster than Gaussian elimination.' Developers out there who maintain matrix packages and linear algebra tools might want to take a peak at the paper. Anyone who has modeled real-world systems will be able to tell you that speedups in linear algebra algorithms have a weighty effect on efficiency in simulations — especially as one approaches the theoretical limits of optimality. This research is currently being presented at the IEEE Symposium on Foundations of Computer Science."

Mortimer.CA writes "In some recent release notes Apple has deprecated their JVM: 'As of the release of Java for Mac OS X 10.6 Update 3, the version of Java that is ported by Apple, and that ships with Mac OS X, is deprecated.' In the past Sun (now Oracle) has always let Apple do this: 'Apple Computer supplies their own version of Java. Use the Software Update feature (available on the Apple menu) to check that you have the most up-to-date version of Java for your Mac.' I wonder how much heads-up Oracle was given for this change, and if the Java team has any code ready to go, or whether they'll have to ramp up porting for Mac OS 10.7 (aka 'Lion')."

tsu doh nimh writes "Microsoft warned today that it is witnessing a huge spike in the exploitation of Java vulnerabilities on the Windows platform, and that attacks on Java security holes now far outpace the exploitation of Adobe PDF bugs. The Microsoft announcement cites research by blogger Brian Krebs, who has been warning for several months that Java vulnerabilities are showing up as the top moneymakers for those peddling commercial crimeware exploitation kits, such as Eleonore, Crimepack and SEO Sploit Pack." Several days ago, Oracle released a patch that fixed 29 Java security flaws.

Lucas123 writes "AOL recently completed the roll out of a 50TB SAN made entirely of NAND flash in order to address performance issues with its relational database. While the flash memory fixed the problem, it didn't come cheap, at about four times the cost of a typical Fibre Channel disk array with the same capacity, and it performs at about 250,000 IOPS. One reason the flash SAN is so fast is that it doesn't use a SAS or PCIe backbone, but instead has a proprietary interface that offers up 5 to 6Gb/s throughput. AOL's senior operations architect said the SAN cost about $20 per gigabyte of capacity, or about $1 million. But, as he puts it, 'It's very easy to fall in love with this stuff once you're on it.'"

Trailrunner7 writes "It's been tried before, but NSS Labs founder Rick Moy says his company's new Exploit Hub — a store front for exploit code — can work. In an interview, he explains why the current market for exploits doesn't work for the good guys, and why zero-day exploits don't help anyone. Above-board markets for software vulnerabilities have been around for close to a decade, but previous efforts to market exploits have had mixed results. The business of selling exploits versus vulnerabilities is fraught with danger, and organizations like WabiSabiLabi have operated eBay-style marketplaces for zero-day exploits for years, but haven't seen exploit writers beating a path to their door. The need for an above-board marketplace that can compete with the black market surely exists, but getting it to work is another matter entirely."

bgweber writes "The StarCraft AI Competition announced last year has come to a conclusion. The competition received 28 bot submissions from universities and teams all over the world. The winner of the competition was UC Berkeley's submission, which executed a novel mutalisk micromanagement strategy. During the conference, a man versus machine exhibition match was held between the top ranking bot and a former World Cyber Games competitor. While the expert player was capable of defeating the best bot, less experienced players were not as successful. Complete results, bot releases, and replays are available at the competition website."

eldavojohn writes "Today roughly marks C++'s first release 25 years ago when about six years of Bjarne Stroustrop's life came to fruition in the now pervasive replacement language for C. It achieved ISO standardization in 1998 and its creator regularly receives accolades. Wired's short interview contains some nice anecdotes including 'If I had thought of it and had some marketing sense every computer and just about any gadget would have had a little 'C++ Inside' sticker on it' and 'I'll just note that I consider the idea of one language, one programming tool, as the one and only best tool for everyone and for every problem infantile. If someone claims to have the perfect language he is either a fool or a salesman or both.' There's some surprising revelations in here, too, as his portable computer runs Windows."

An anonymous reader writes "As reported by hobbyist calculator programmers, Casio has recently unveiled new graphing calculator models, the Casio fx-CG10/20 series, less than a year after Texas Instruments released the TI-Nspire Touchpad. The calculators features a 65536 colors screen (16-bit) with a resolution of 384x216 pixels, 16 MB of Flash memory (10 available for the user) and 140 hours of battery life. The calculators will retail starting at $129.99. Although Casio's new calculator official page have limited information about the calculator programming capabilities and processor speed, could this eventually mark the end of TI's reign in North American schools?"

GMGruman writes "Oracle's decision to shift focus from the Harmony Java open source project to OpenJDK seems innocuous enough — but InfoWorld's Josh Fruhlinger explains it's part of an effort to derail Google's mobile Android OS by gutting the open source project that Android has been driven by. IBM has signed on, apparently in return for getting the Java Community Process reactivated, leaving Google in a bind."

An anonymous reader writes "I'm an Applied Math grad student who knows a bit of Mathematics and a bit of programming. C++ is my first programming language — I am decent at it. I wish to start contributing to a numerical library with two purposes — contribute to open source and develop my C++ skills at the same time. I looked at the Boost libraries and joined the developer list. However, I have no idea on how to start contributing. I'm not an expert in template programming, having written only toy programs to understand that concept. I've used some of the OOP constructs like inheritance,but only for very small projects. Do you have any tips on how to get started on contribution? Are there any other emerging numerical libraries to which I can contribute? Are there any other avenues where I can contribute to open source and improve programming skills?"

eldavojohn writes "It's no secret that the actual cost of software is very complicated. Sure, the companies that write software are spending money on it, but when that software is released, it doesn't stop costing money. You can probably think of a number of relatively tiny things that add up — especially if you're a system administrator — like the man-hours spent patching software to avoid a nasty infection spreading quickly. The bigger debt is that old piece of software you paid a bunch of money for back in 1998 that you're critically dependent on, but it has no support and hasn't been updated in years due to any number of reasons. Well, the National Science Foundation paid Gartner almost half a million dollars to find out what it truly costs to bring an organization to a fully supported environment. According to Gartner, this hidden liability or 'IT debt' is at $500 billion worldwide right now, and in five years it will be at $1 trillion. Along similar lines, a company called Cast that makes software quality tools reported that your average business application comes with a million in IT debt (PDF). And if that's not misapplied enough for you, they estimate that the debt is $2.82 per line of code in the application and also that it's on average higher in the government sector."

jamie tips this mind-blowing data visualization concept from (naturally) data visualization researcher Michael Ogawa, who explains that it was inspired by "this XKCD comic. It represents characters as lines that converge in time as they share scenes. Could this technique be adapted for software developers who work on the same code?"

ed1023 writes "Currently I am teaching a 101 class on computers. It is more of a 'demystifying the black box' type of class. The current topic is computer viruses; I am looking for a virus with which I can infect the lab computers (only connected to local network, no outside network connection) that would be easy for the students to remove by hand. Can the Slashdot community point me in any directions? Is there an executable out there that would work, or do I try to write one myself, or is there one that is written that I can compile myself?"

eldavojohn writes "Linux Kernel Development Third Edition by Robert Love is the perfect book for the beginning or intermediate Linux kernel hacker. It provided me an excellent bridge between the high level introduction I had in college (from Operating Systems Concepts) and the actual kernel code. The best part about this book is that the chapters are — like the kernel — modular, and allow the reader to dig down in a particular part if they have a specific interest. This, in conjunction with Love's indications of which files and code snippets contain the logic, gave me confidence to clone the kernel, make tiny adjustments, compile and run. At four hundred pages, the book is a long read, but for kernel newbies like me it's a better alternative to jumping into the millions of lines of code. While you might find this information in pieces floating around online, this book balances clarity with brevity in an exceptional manner. It should also be noted that this book defaults to the x86 architecture when explaining architecture-sensitive parts of the kernel (with 64-bit differences occasionally outlined)."
