An anonymous reader writes "I have deep experience programming in many languages, and I've some exposure to SQL through PostgreSQL. My math goes so far as trig and algebra, with a little statistics. So far, I've learned enough to be dangerous: mostly via other people's code, experimenting, the PostgreSQL docs, etc. I've been successful using the DB in various ways, but I know I am missing a great deal (and probably doing it wrong, at that.) When DB articles come up on Slashdot, I don't recognize a good deal of the terminology. What is the best way for a technical person to learn SQL/DB work using PostgreSQL? Books? Tutorials? I should mention I don't have local access to a university or people with DB knowledge; have to do this on my own, so books or the Internet are pretty much my options."

First time accepted submitter jasax writes "As an Amazon frequent buyer, I rely quite a lot on reviews of the books I want. However, some caution is in order: the (bad) quality of Amazon's reviews and reviewers under the Amazon Vine program has already been news in Slashdot. Today I was shocked by a practical result of that program. This second edition (published in 2012) of a very specialized system identification book has 12 reviews: the oldest (dated 2007) certainly targets the first edition. The remaining 11 reviews are all from 'Vine Reviewers' (VRs). All seem to be ignorant of what 'System Identification in the Frequency Domain' really is. None of the reviews is tagged with a 'Verified Amazon Purchase'; most (if not all) are 'small talk reviews' peppered with technical phrases cloning the publisher's book description, and some of the reviews are ridiculous, to say the least. If this sample of reviewing by VRs really is the norm, then the bottom line is that the Vine program is totally irrelevant and unreliable — at least for technical books."
grahamsaa writes "I work at medium sized company that offers a number of products that rely fairly heavily on backend databases, some of which are hundreds of gigabytes and deal with hundreds or thousands of queries per second. Currently, we're using a mix of Postgres, Oracle, and MySQL, though we're working hard to move everything to Postgres. The products that are still on MySQL and Oracle were acquisitions, so we didn't get to choose the RDBMS at the time these products were designed. So far, we've been very happy with Postgres, but I know next to nothing about Oracle. It's expensive and has a long history of use in large enterprises, but I'm curious about what it offers that Postgres might not — I'm not saying this because I think that sticking with Oracle would be a good idea (because in our case, it probably isn't), but I'm curious as to how some companies justify the cost — especially considering that EnterpriseDB makes transitioning from Oracle to Postgres feasible (though not painless) in most cases. For those that use Oracle — is it worth the money? What's keeping you from switching?"
An anonymous reader writes "As promised, Mozilla today announced the release of Firefox OS Simulator 4.0 with a focus on developers who want to make money in the Firefox Marketplace. You can download the new version now for Windows, Mac, and Linux from Mozilla Add-Ons. First and foremost, the new simulator supports test receipts for paid apps: each app's dashboard features a drop-down menu where you can select a receipt type. Choosing one of these will have the simulator add-on downloading a test receipt from a Marketplace receipt service and reinstalling the app using it. This lets developers test receipt verification with whatever receipts types they may require (valid, invalid, and refunded)."

In trying to replace the program, the Pentagon spent a billion dollars and wasn't successful."
cyclomedia writes "Over a number of years my company has managed to slowly shift from a free-for-all (pick a developer at random and get them to do what you want) to something resembling Agile development with weekly builds. But we still have to deal with constant incoming feature changes and requests that are expected to be included in this week's package. The upshot is that builds are usually late, not properly tested and developers get the flak when things go wrong. I suspect the answer is political, but how do we make things better? One idea I had was that every time a new request comes in — no matter how small — the build gets pushed back by 24 or even 48 hours. I'd love to hear your ideas or success stories.

dcblogs writes "There are about 18.2 million software developers worldwide, a number that is due to rise to 26.4 million by 2019, a 45% increase, says Evans Data Corp. in its latest Global Developer Population and Demographic Study. Today, the U.S. leads the world in software developers, with about 3.6 million. India has about 2.75 million. But by 2018, India will have 5.2 million developers, a nearly 90% increase, versus 4.5 million in the U.S., a 25% increase though that period, Evans Data projects. India's software development growth rate is attributed, in part, to its population size, 1.2 billion, and relative youth, with about half the population under 25 years of age. Rapid economic growth is fueling interest in development. India's services firms hire, in many cases, thousands of new employees each quarter. Consequently, IT and software work is seen as clear path to the middle class for many of the nation's young. For instance, in one quarter this year, Tata Consultancy Services added more than 17,000 employees, gross, bringing its total headcount to 263,600. In the same quarter of 2010, the company had about 150,000 workers."
itwbennett writes "U.C. Berkeley researchers have determined that crowdsourcing bug-finding is a far better investment than hiring employees to do the job. Here's the math: Over the last three years, Google has paid $580,000 and Mozilla has paid $570,000 for bugs found in their Chrome and Firefox browsers — and hundreds of vulnerabilities have been fixed. Compare that to the average annual cost of a single North American developer (about $100,000, plus 50% overhead), 'we see that the cost of either of these VRPs (vulnerability reward programs) is comparable to the cost of just one member of the browser security team,' the researchers wrote (PDF). And the crowdsourcing also uncovered more bugs than a single full-time developer could find."
theshowmecanuck writes "I'm working at a small- to medium-sized company that creates software for mobile devices, but came from a 'large enterprise' world before. I see node.js being used increasingly in smaller companies (including ours) or in web/mobile related software. Meanwhile we see languages like Java/JEE, C/C++, and .NET continue to be used for medium-to-large enterprise corporate software. Compared to the status quo in the enterprise (JEE/C/C++/.NET ... and yes, maybe even COBOL) maybe Slashdotters can chime in on how they see Node.js in this role. I'm thinking of things like complexity of business logic (dependencies, workflows, linear processes, etc), transaction support (for processes in general and database support), messaging services, etc. Also, what is the state of Node.js in terms of paradigms like application containers, where much of the 'plumbing' is already set up for you (one of the main benefits of JEE application containers)? But there is also the question of maintainability, deployment, and ongoing operations. What say you, Slashdot?"
Nerval's Lobster writes "In the fall of 2014, 20 promising video game developers will begin a yearlong (and free) program at the University of Texas at Austin, where they will study under some of the gaming industry's most successful executives. 'The idea is to get the best of the best of the best, run them through a Navy Seals boot camp of sorts and not force them to worry about "how do I pay the rent and buy groceries,"' said program leader Warren Spector, who is responsible for creating well-known games such as Deus Ex. 'Fingers crossed, when we start delivering graduates who can contribute in major ways to the development of future games, that philanthropy will continue.' In a wide-ranging interview, Spector also talked about how his future students will be graduating into an industry in which 'every business model is broken, which is either terrifying or an opportunity depending on how you look at it.' Focus groups, analysis of historical trends, and aggregated game review scores may be comforting to number crunchers, but the majority of game projects still end up as commercial failures. Spector ultimately believes the people who actually make the games are going to make better decisions than the number crunchers. 'We've got to be looking forward and any time you start bringing data into it, you're not," Spector said. "I pitched a Lego construction game in 1989, and guess what: Minecraft is basically a Lego construction game. But at the time I was told "no, that won't work." I pitched a western game and the response was "westerns don't sell." And then Red Dead Redemption came out. Stuff doesn't sell until someone makes one that sells, and no amount of data can reveal what new thing is going to sell. The metrics and data guys, and the publishing guys will never come up with the next big thing.'""

One possible lesson: radically overshooting your crowdfunding goal can cause you to wildly expand your ambitions, leading to a project that can't be tamed."
Michael Ross writes "As a hugely popular scripting language with an 18-year history, PHP has been the topic of countless computer language books. One of the most comprehensive offerings has been Programming PHP, published by O'Reilly Media. The first edition appeared in March 2002, and was written by Rasmus Lerdorf (the original developer of PHP) and Kevin Tatroe. A second edition was released in May 2006, and saw the addition of another co-author, Peter MacIntyre. With the many changes to the language during the past seven years, the book has again been updated, to cover all of the major new features made available in version 5 of PHP."

theodp writes "The 1976 science fiction film Logan's Run depicts a dystopian future society where life must end at the age of 30. So, it's a world that kind of resembles today's Silicon Valley, where the NY Times reports that the median age of workers is 29 years old at Google and 28 years old at Facebook. The report that technology workers are young — really young — comes on the heels of other presumably-unrelated stories that Silicon Valley execs can't find enough skilled workers and no one would fund Doug Engelbart in the last four decades of his life. On the bright side, at least old techies don't die in Silicon Valley — they just can't get hired."
An anonymous reader writes "Following up on an experiment from December, Michael Hansen has recorded video of programmers of varying skill levels as the read and evaluate short programs written in Python. An eye tracker checks 300 times per second to show what they look at as they mentally digest the script. You can see some interesting differences between experts and beginners: 'First, Eric's eye movements are precise and directed from the beginning. He quickly finds the first print statement and jumps back to comprehend the between function. The novice, on the other hand, spends time skimming the whole program first before tackling the first print. This is in line with expectations, of course, but it's cool to see it come out in the data. Another thing that stands out is the pronounced effect of learning in both videos. As Eric pointed out, it appears that he "compiled" the between function in his head, since his second encounter with it doesn't require a lengthy stop back at the definition. The novice received an inline version of the same program, where the functions were not present. Nevertheless, we can see a sharp transition in reading style around 1:30 when the pattern has been recognized.'"
WebMink writes "A discussion in the Debian community reveals that last month Oracle quietly disclosed a change for the embedded BerkeleyDB database from the quirky Sleepycat License to the Affero General Public License (AGPL) in future versions. AGPL is only compatible with GPLv3 and treats web deployment as a trigger to license compliance, so developers using BerkeleyDB will need to check their code is still legally licensed. Even if they had made the switch in the interests of advancing software freedom it would be questionable to force so many developers into a new license compatibility crisis. But it seems likely their only motivation is to scare more people into buying proprietary licenses. Oracle are well within their rights, but developers are likely to treat this as a betrayal. As a poster in the Debian thread says, "Oracle move just sent the Berkeley DB to oblivion" because there are some great alternatives, like OpenLDAP's LMDB."

dcblogs writes "The strike by San Francisco Bay Area Rapid Transit (BART) workers this week is a clear and naked display of union power, something that's probably completely alien to tech professionals. Tech workers aren't organized in any significant way except through professional associations. They don't strike. But the tech industry is highly organized, and getting more so. Industry lobbying spending has been steadily rising, reaching $135 million last year, almost as much as the oil and gas industry. But in just one day of striking, BART workers have cost the local economy about $73 million in lost productivity due to delays in traffic and commuting. Software developers aren't likely to unionize. As with a lot of professionals, they view themselves as people with special skills, capable of individually bargaining for themselves, and believe they have enough power in the industry to get what they want, said Victor Devinatz, a professor of management and quantitative methods at Illinois State University College of Business. For unions to get off the ground with software workers, Devinatz said, 'They have to believe that collective action would be possible vehicle to get the kinds of things that they want and that they deserve.'"

CowboyRobot writes "ACM has an article about how Netflix conducts its resilience testing. Instead of the GameDays used by sites such as Amazon and Google, Netflix uses what they call The Simian Army, based on the philosophy that 'Resilience can be improved by increasing the frequency and variety of failure and evolving the system to deal better with each new-found failure, thereby increasing anti-fragility.' While GameDay exercises are like a fire-drill, with scheduled exercises where failure is manually introduced or simulated, the Simian Army relies on failure in the live environment induced by autonomous agents known as 'monkeys.' Chaos Monkey randomly terminates virtual instances in a production environment that are serving live customer traffic. Chaos Gorilla causes an entire Amazon Availability Zone to fail. And Chaos Kong will take down an entire region of zones. 'What doesn't kill you makes you stronger' and Netflix hopes that by constantly protecting itself from internal onslaught, they will become increasingly 'anti-fragile — growing stronger from each successive stressor, disturbance, and failure.'"

Nerval's Lobster writes "Once upon a time, Salesforce CEO Marc Benioff and Oracle CEO Larry Ellison took what seemed like inordinate amounts of pleasure in firing off verbal broadsides at each other. In 2011, for example, Ellison referred to Salesforce as 'the roach motel of clouds' and 'a very bad security model.' But Benioff's given as good as he's gotten, swiping at Oracle's early cloud efforts as 'cloud in a box' and 'just another server.' But oh, how things change: Ellison and Benioff have revealed that their firms would come together in a joint effort. They were on their best behavior during a conference call this week. 'The Oracle database has been a key part of Salesforce's infrastructure from the very beginning of our company 14 years ago,' Benioff told Ellison at one point, according to a transcript posted on ZDNet. 'Absolutely the best decision we ever made was to go with Oracle.' Why the sudden reversal? Simply put, after years of sticking with a hardware-and-software model, Oracle now has cloud religion. For Salesforce, the benefits are a little murkier, but some analysts think that Salesforce will be able to leverage Oracle's name to gain a heightened profile with businesses. But can Benioff and Ellison continue to play nice?"
An anonymous reader writes "While the landmark immigration bill (full text PDF), which recently passed the U.S. Senate, is being hailed as bringing crucial reforms that will vastly improve the state of immigration in this country, there is a provision in it that is seeing relatively little discussion: section 4101, a 'market-based' increase in the amount of H-1B visas for skilled workers. 'The pitched arguments of both sides, which are likely to resurface in the House when it takes up its version of an immigration overhaul, cloud a complicated reality. There is little empirical evidence to suggest that foreign engineers displace American engineers as a whole. If anything, one recent study suggests, the growth of immigrant workers in American companies helps younger American technical workers — more of them are hired and at higher-paying jobs — but has no noticeable consequences, good or bad, on older workers.'"
theodp writes "Over at Dr. Dobb's, Editor-in-Chief Andrew Binstock has a nice rant on The Misplaced Obsession with Simplicity. 'Any idiot can write complex code,' goes the old maxim, 'the true art is writing simple code.' Right, Andrew? Wrong (mostly). Binstock explains, 'It's not true that any idiot can write complex code. Complex code is difficult, often very difficult, to write. It's entirely true that it's more difficult to maintain, too. But that's the nature of complexity. Some things are intensely difficult to express in code and they require complexity, simply because they're not inherently simple.' After citing the complex-but-necessarily-so code of Al Aho and sometimes-misguided reverence for cyclomatic complexity limits to help make his point, Binstock concludes, 'My view of simplicity is unemotional and free of idolatry because I define it with respect to complexity, rather than the other way around: Simplicity is the quality of code that is no more complex than required to express the underlying complexity. In this way, simple code can be intensely complex. There is no inherent good/bad dichotomy.'"

An anonymous reader writes "Want to gain some of the benefits of open source software development but not sure how to finance it? According to Monty Widenius, creator of MySQL and MariaDB, one solution could be the 'business source' license. While 'open source friendly' rather than open source, Monty blogged, it is intended to offer a viable alternative for companies that want to 'do development and compete with closed source companies on similar economic terms.' Business source starts out with similar benefits as an OSD-compliant license: the source code is visible and can be used freely by all but a small segment that has to pay (the developing company chooses the segment). Then, after a few years, the license automatically changes to an open source license. Monty recently explained the details of business source, and gave a sample license. (Oh, and not to worry, he notes – MariaDB is and will remain GPL.)"

And you may take particular pride in maintaining that 'artisan' role. After all, it's mostly up to you to set up new users and their machines, fix current problems, manage the servers and their software, create databases and their user accounts, and try to keep the network and user configurations as uniform as possible despite running several different brands--and vintages--of hardware and software. However, warns infrastructure consultant John Arundel, '[b]eyond ten or so servers, there simply isn't a choice. You can't manage an infrastructure like this by hand. If you're using a cloud computing architecture, where servers are created and destroyed minute-by-minute in response to changing demand, the artisan approach to server crafting just won't work.' In his new book, Puppet 3 Beginner's Guide, Arundel emphasizes: 'Manual configuration management is tedious and repetitive, it's error-prone, and it doesn't scale well. Puppet is a tool for automating this process.'" Read below for the rest of sagecreek's review.

Well truth is Subversion is still going strong and just released version 1.8. While Git is still faster for some things, Greg Stein, the former chair of the Apache Software Foundation, figures SVN is better than Git at lots of things.
