eldavojohn writes "A teacher is offering empirical evidence that when you're mining data, augmenting data is better than a better algorithm. He explains that he had teams in his class enter the Netflix challenge, and two teams went two different ways. One team used a better algorithm while the other harvested augmenting data on movies from the Internet Movie Database. And this team, which used a simpler algorithm, did much better — nearly as well as the best algorithm on the boards for the $1 million challenge. The teacher relates this back to Google's page ranking algorithm and presents a pretty convincing argument. What do you think? Will more data usually perform better than a better algorithm?"

LuckyLefty01 writes "I'm 21, going to college, and working part time doing odd jobs like math tutoring. In the past nine months or so, I've discovered and taken to programming (so far mostly C/C++/Obj-C). I am now looking seriously at something in this area as an eventual full time job. Since I don't have much scheduled this coming summer, it would be great to try to get a job of some sort at a tech-related company in order to get some practical experience in the field. Even if I don't have the background to get a job involving actual programming, I think that the knowledge of how such a company works would be valuable. Fortunately, I live in the SF Bay Area, so there should be plenty of companies around. I'm flexible about what I'm going to be doing, and very willing to learn just about anything anybody cares to teach me. If there's some (or even quite a bit of) boring grunt work involved, I can do that too. What type of job would benefit an aspiring but inexperienced programmer the most? What methods might I use to find such a job?"

simoniker writes "Over at Dr. Dobb's, C++ creator Bjarne Stroustrup has given an in-depth interview dealing with, among other things, the upcoming C++0x programming standard, as well as his views on the past and future of C++. He comments in particular on some of the difficulties in educating people on C++: 'In the early days of C++, I worried a lot about "not being able to teach teachers fast enough." I had reason to worry because much of the obvious poor use of C++ can be traced to fundamental misunderstandings among educators. I obviously failed to articulate my ideals and principles sufficiently.' Stroustrup also notes, 'Given that the problems are not restricted to C++, I'm not alone in that. As far as I can see, every large programming community suffers, so the problem is one of scale.' We've discussed Stroustrup's views on C++ in the past."

ZDOne writes "Apple might have finally come around to allowing third party developers to create applications for the iPhone, but only up to a point. ZDNet UK claims Apple is leaving itself vulnerable to the competition and to a loss of lustre by blocking background tasks on the device. The author notes, 'Perhaps it doesn't trust application designers or users very much. Perhaps it wants the best software for itself, where it can limit what it can do in order not to upset its telco friends. Whatever the reason, it reflects badly on Apple. The iPhone is not an iPod; it's a smartphone connecting to a universe of fast-changing data on behalf of innovation-hungry users. The sooner it stops pretending to be a 1981 IBM PC, the better it will be for everyone.'"

For months now, I've been geeked about Amazon's EC2 as a web hosting service. But until today, in my opinion, it wasn't ready for prime time. Now it is, for two reasons. One, you can get static IPs, so if an outward-facing VM goes down you can quickly start another one and point your site's traffic to it without waiting for DNS propagation. And two, you can now separate your VMs into "physically distinct, independent infrastructure" zones, so you can plan to keep your site up if a tornado takes out one NOC. If I were developing a new website I'd host it there; buying or leasing real hardware for a startup seems silly. If you have questions, or especially if you know something about other companies' virtual hosting options, post comments -- let's compare notes.

stoolpigeon writes "IBM has made a move to support open source RDBMS PostgreSQL by investing in EnterpriseDB, a company that supports PostgreSQL as well as selling their own proprietary extensions to the database product. IBM participated in a $10 million funding round, though the article doesn't say how much they invested. In the past EnterpriseDB has primarily advertised itself as an Oracle competitor, though the article says, 'Derek Rodner, EnterpriseDB's director of product strategy, explained that Postgres Plus 8.3 also adds in new application quick starts which are supposed to help with installation issues. They will also help in EnterpriseDB's battle against MySQL for open source database supremacy.'"

simoniker writes "In a new weblog post on Dobbs Code Talk, Intel's James Reinders discusses the growth of concurrency in programming, suggesting that '...programming for multi-core is catching the imagination of programmers more in Japan, China, Russia, and India than in Europe and the United States.' He also comments: 'We see a significantly HIGHER interest in jumping on a parallelism from programmers with under 15 years experience, verses programmers with more than 15 years.' Any anecdotal evidence for or against from this community?"

An anonymous reader sends the story of the rediscovery of an original painting of Ada Byron at about age 4, the girl who was to become Countess Lovelace and the world's first computer programmer. A US Army sergeant in Tajikistan caught wind of an eBay auction of a 180-year-old painting of Ada Byron, with provenance; he notified a programmer buddy in Texas, who won the auction.

covertbadger notes a developer's blog entry on a novel way of judging progress in refactoring code. "Software quality tools can never completely replace the gut instinct of a developer — you might have massive test coverage, but that won't help with subjective measures such as code smells. With Wodehouse-style refactoring, we can now easily keep track of which code we are happy with, and which code we remain deeply suspicious of."

Jeremy Martin writes "Well I suppose it's an undeniable fact about us programmer-types — every now and then we just can't help but get excited about something really nerdy. For me right now, that is definitely JavaScript 2.0. I was just taking a look at the proposed specifications and I am really, truly excited about what we have coming."

wraith808 points out a story about remarks made by the CEO of software and game development company Stardock about sales in the PC game industry. His suggestion to other developers is simple: ignore the software pirates. From Ars Technica: "'So here is the deal: When you develop for a market, you don't go by the user base. You go by the potential customer base. That's what most software companies do. They base what they want to create on the size of the market they're developing for,' Wardell writes on his blog. 'But not PC game developers.' Don't let people who aren't your audience control the titles you make, and ignore piracy. This is much like Trent Reznor's strategy, although the execution is different. Instead of worrying about pirates, just leave the content out in the open. The market Reznor plays to will still buy the music; he's simply stopped worrying about the pirates. He came to the same conclusion: they weren't customers, they might never be customers, so spending money to try to stop them serves no purpose."

eldavojohn writes "If you're a Web developer, you should check out a quick post about the number of types, methods, & fields in the .NET framework. This was done using NDepend. The numbers are quite large — e.g. 39,509 types. The blogger went on to generate tree maps and a dependency matrix."

kulbirsaini writes "Google has announced the list of accepted organizations for the Google Summer of Code 2008. 'No doubt many would-be Summer of Code students are wondering what their next steps should be. We've changed the program timeline this year, leaving a week in between the announcement of accepted mentoring organizations and opening for student applications. Use this week to meet your potential mentors and discuss your project ideas with them, and keep on eye on the program mailing lists, as we'll post notes about additional resources for learning about our mentoring organizations.'"

psycho12345 sends in an article in News.com on a study, sponsored by Verizon and Yale, finding that if P2P software is written more 'intelligently' (by localizing requests), the effect of bandwidth hogging is vastly reduced. According to the study, redoing the P2P into what they call P4P can reduce the number of 'hops' by an average of 400%. With localized P4P, less of the sharing occurs over large distances, instead making requests of nearby clients (geographically). The NYTimes covers the development from the practical standpoint of Verizon's agreement with P2P company Pando Networks, which will be involved in distributing NBC television shows next month. So the network efficiencies will accrue to legal P2P content, not to downloads from The Pirate Bay.

schliz notes a development out of Rensselaer Polytechnic Institute where researchers have successfully created an artificially intelligent four-year-old capable of reasoning about his beliefs to draw conclusions in a manner that matches human children his age. The technology, which runs on the institute's supercomputing clusters, will be put to use in immersive training and education scenarios. Researchers envision futuristic applications like those seen in Star Trek's holodeck."

sipmeister writes "Two computer scientists who work for enterprise software giant SAP have shown that open source is growing at an exponential rate. Not only is the code base growing exponentially, but also the number of viable projects. Researchers Amit Deshpande and Dirk Riehle analyzed the database of open source startup ohloh.net and looked at the last 16 years of growth in open source. They consistently got the best fit for the data using an exponential model. Relating this to open source market revenue, Desphande and Riehle conclude that open source is eating into closed source at a non-trivial pace."

christo writes "In what appears to be a first, the US House of Representatives now has a Congressman with coding skills. Democratic Representative Bill Foster won a special election this past Saturday in the 14th Congressional District of Illinois. Foster is a physicist who worked at Fermilab for 22 years designing data analysis software for the lab's high energy particle collision detector. In an interview with CNET today, Foster's campaign manager confirmed that the Congressman can write assembly, Fortran and Visual Basic. Will having a tech-savvy congressman change the game at all? Can we expect more rational tech-policy? Already on his first day, Foster provided a tie-breaking vote to pass a major ethics reform bill."

An anonymous reader writes "Apple's iPhone software development kit is already drawing complaints due to the strict terms of service. Voice over IP apps like Skype that attempt to use the cellular data connection will be blocked. Competing web browsers Firefox and Opera are forbidden. Even Sun is now backpedaling on its recent announcement of a java port, noting that there are some legal issues. Critics are already comparing Apple's methods to Comcast's anti-net neutrality filtering, and Microsoft's Netscape-killing antitrust tactics. Could Apple face government regulators?"

Somecallmechief writes "Firefox 3 Beta 4 is now available for download.

MOBE2001 writes "There is widespread disagreement among experts on how best to design and program multicore processors, according to the EE Times. Some, like senior AMD fellow, Chuck Moore, believe that the industry should move to a new model based on a multiplicity of cores optimized for various tasks. Others disagree on the ground that heterogeneous processors would be too hard to program. The only emerging consensus seems to be that multicore computing is facing a major crisis. In a recent EE Times article titled 'Multicore puts screws to parallel-programming models', AMD's Chuck Moore is reported to have said that 'the industry is in a little bit of a panic about how to program multicore processors, especially heterogeneous ones.'"
