MySQL Founders Reunite To Form SkySQL 215

Posted by timothy
from the together-again-at-last dept.
mikejuk writes "The founders of the original MySQL, the open-source database, are getting back together in a merger between Monty Program and SkySQL. SkySQL was created by around two dozen former MySQL executives and investors after Oracle bought MySQL from Sun. Widenius started Monty Program AB and created the MariaDB database from some of MySQL's open source code. The merger will provide a stronger rival to MySQL, so reassuring users who are worried about Oracle's future plans for the database."

Stop Standardizing HTML 302

Posted by Unknown Lamer
from the remember-xhtml-2.0 dept.
pfignaux writes with an interesting view on the place of centralized standardization in modern browsers. From the article: "When HTML first appeared, it offered a coherent if limited vocabulary for sharing content on the newly created World Wide Web. Today, after HTML has handed off most of its actual work to other specifications, it's time to stop worrying about this central core and let developers choose their own markup vocabularies and processing." Instead, the author proposes that CSS, Javascript+DOM, the W3C's accessibility framework, and Web Components are sufficient to implement the rendering of smaller, domain-specific markups.

Overconfidence: Why You Suck At Making Development Time Estimates 297

Posted by Soulskill
from the i-blame-the-schools dept.
Dan Milstein from Hut 8 Labs has written a lengthy post about why software developers often struggle to estimate the time required to implement their projects. Drawing on lessons from a book called Thinking Fast and Slow by Dan Kahneman, he explains how overconfidence frequently leads to underestimations of a project's complexity. Unfortunately, the nature of overconfidence makes it tough to compensate. Quoting: "Specifically, in many, many situations, the following three things hold true: 1- 'Expert' predictions about some future event are so completely unreliable as to be basically meaningless 2- Nonetheless, the experts in question are extremely confident about the accuracy of their predictions. 3- And, best of all: absolutely nothing seems to be able to diminish the confidence that experts feel. The last one is truly remarkable: even if experts try to honestly face evidence of their own past failures, even if they deeply understand this flaw in human cognition they will still feel a deep sense of confidence in the accuracy of their predictions. As Kahneman explains it, after telling an amazing story about his own failing on this front: 'The confidence you will experience in your future judgments will not be diminished by what you just read, even if you believe every word.'"

Dropcam CEO's Beef With Brogramming and Free Dinners 400

Posted by timothy
from the why-is-the-incinerator-so-big? dept.
waderoush writes "Plenty of technology companies serve free breakfast, lunch, and dinner to their employees, but Dropcam CEO Greg Duffy says that's a form of mind control designed to get people to to work late. To keep employees happy, Duffy says, it's better to make them go home to their families for dinner. Some other suggestions from the San Francisco video monitoring startup: don't fill your engineering department with young, single, childless males (aka brogrammers). Keep your business model simple by making actual stuff that you can sell for a profit. And don't hire assholes. Why pay attention to Duffy's advice? Because Dropcam has a 100 percent employee retention rate — no one who has joined the 4-year-old company has ever left."

Wikipedia Moved To MariaDB 5.5 133

Peetke writes "As we all know Oracle is not the biggest friend to the Open Source Community. Long standing OSS supporter Wikipedia has now moved from an optimized fork of MySQL 5.1 to MariaDB 5.5, for both its English and German sites. Wikipedia expects all other languages to follow within a month. Performance-wise, this move has no big implications, but it will ensure our biggest community database will live long and prosper."

Harvard/MIT Student Creates GPU Database, Hacker-Style 135

Posted by Unknown Lamer
from the search-faster dept.
First time accepted submitter IamIanB writes "Harvard Middle Eastern Studies student Todd Mostak's first tangle with big data didn't go well; trying to process and map 40 million geolocated tweets from the Arab Spring uprising took days. So while taking a database course across town at MIT, he developed a massively parallel database that uses GeForce Titan GPUs to do the data processing. The system sees 70x performance increases over CPU-based systems, and can out crunch a 1000 node MapReduce cluster, in some cases. All for around $5,000 worth of hardware. Mostak plans to release the system under an open source license; you can play with a data set of 125 million tweets hosted at Harvard's WorldMap and see the millisecond response time." I seem to recall a dedicated database query processor that worked by having a few hundred really small processors that was integrated with INGRES in the '80s.

In Development: An Open Source Language For Cell Programming 31

Posted by timothy
from the tab-A-in-slot-T dept.
hessian writes with a story at Wired (excerpt below) about a project from Drew Endy of the International Open Facility Advancing Biotechnology, or BIOFAB, to standardize a programming language connecting genetic information from DNA to the cell components that DNA can create. "The BIOFAB project is still in the early stages. Endy and the team are creating the most basic of building blocks — the 'grammar' for the language. Their latest achievement, recently reported in the journal Science, has been to create a way of controlling and amplifying the signals sent from the genome to the cell. Endy compares this process to an old fashioned telegraph. 'If you want to send a telegraph from San Francisco to Los Angeles, the signals would get degraded along the wire,' he says. "At some point, you have to have a relay system that would detect the signals before they completely went to noise and then amplify them back up to keep sending them along their way.""

Ask Slashdot: Service-Heavy FOSS Hosting? 75

Posted by timothy
from the for-work-and-play dept.
An anonymous reader writes "For many of us our hosting providers are a way to hone our skills as well as run a business. Which provider out there gives the best bang for the buck for a FOSS developer? Virtually everybody provides Perl, PHP, Ruby, MySQL / MariaDB etc. but where can one get easy and cheap access to a stuff like NodeJS and Big Data? Companies such as Pair Networks are great but not quite on the mark with any of their service offerings for somebody looking to test out real world scenarios with these technologies from a hosted stance. Obviously hosting from home is always an option but that has the penalty of administration, backup, DR planning, bigger security footprint etc. and for those of us whose time is balanced between making money and friends / family time that's not very appealing."

Localized (Visual) Programming Language For Kids? 185

Posted by timothy
from the because-english-sometimes-sucks dept.
First time accepted submitter jimshatt writes "I want my kids to play around with programming languages. To teach them basic concepts like loops and subroutines and the likes. My 8-year-old daughter in particular. I've tried Scratch and some other visual languages, but I think she might be turned off by the English language. Having to learn English as well as a programming language at the same time might be just a little too much. I'd really like to have a programming language that is easy to learn, and localized or localizable. Preferably cross-platform, or browser-based, so she can show her work at school (Windows) as well as work on in at home (Debian Linux). By the way, she speaks Dutch and Danish, so preferably one of those languages (but if it's localizable I can translate it myself). Any suggestions?"

Red Hat 'Fedora-izes' JBoss With New WildFly Java Application Server 40

darthcamaro writes "The JBoss Application Server is no more. Just like Red Hat killed Red Hat Linux in 2003 to make way for Fedora, the same is now happening with JBoss and the new WildFly project. 'There was of course the application server, there are a number of JBoss commercial products, there was the community site, etc., so when you asked someone "What is JBoss?" the answer was varied,' Jason Andersen, director, product line management, at Red Hat, explained. 'What we wanted to do was cement the idea that JBoss is a portfolio of middleware products and not just the application server.'"

Java 8 Delayed To Fix Security 135

Posted by Soulskill
from the projected-release-2047 dept.
mikejuk writes "Java Development Kit 8, planned for September 2013, is being delayed until next year because of 'a renewed focus on security.' Java has been having security publicity problems recently, but Oracle now seems to be taking them more seriously. Mark Reinhold, chief architect of the Java platform group, said, 'Maintaining the security of the Java Platform always takes priority over developing new features, and so these efforts have inevitably taken engineers away from working on Java 8.' The major change still to be made to Java 8 is Project Lambda, which Reinhold says is 'the sole driving feature of the release.' He laid out alternatives, such as dropping Lambda from this release, but said Oracle has decided instead to wait until Lambda is ready. The revised schedule for JDK 8 has a developer preview scheduled for September, a release candidate scheduled for January 2014, and general availablity scheduled for March 2014. The delay means that Java SE 9 will probably be released in early 2016, rather than late 2015."

Oracle Fixes 42 Security Vulnerabilities In Java 211

Posted by samzenpus
from the patching-things-up dept.
wiredmikey writes "Oracle released its quarterly Critical Patch Update (CPU) for April, which addressed a whopping 128 security issues across multiple product families. As part of its update, Oracle released a Java SE Critical Patch Update to plug 42 security holes in Java, 19 with base CVE score of 10 (the highest you can go) and 39 related to the Java Web Start plugin which can be remotely exploited without authentication. According to security analyst Wade Williamson, organizations need to realize that Java will continue to pose a significant risk. 'The first step is for an organization to understand precisely where and why Java is needed,' Williamson wrote. 'Based on the rate of newly discovered vulnerabilities, security teams should assume that Java is and will continue to be vulnerable.' Organizations should to take a long, hard look at Java and answer for themselves if it's worth it, Williamson added. Due to the threat posed by a successful attack, Oracle is strongly recommending that organizations apply the security fixes as soon as possible."

Most Projects On GitHub Aren't Open Source Licensed 630

Posted by timothy
from the na-und-was-meinst-du? dept.
PCM2 writes "Kids these days just don't care about open source. That's the conclusion of the Software Freedom Law Center's Aaron Williamson, who analyzed some 1.7 million projects on GitHub and found that only about 15% of them had a clearly identifiable license in their top-level directories. And of the projects that did have licenses, the vast majority preferred permissive licenses such as the MIT, BSD, or Apache licenses, rather than the GPL. Has the younger generation given up on ideas like copyleft and Free Software? And if so, what can be done about it?" Not having an identifiable license is one thing, but it seems quite a stretch to say that choosing a permissive open source license is "not caring"; horses for courses.

Google Forbids Advertising On Glass 274

The internet company has explicitly and openly said that the Glass platform should and must be clean and clear of any ads whatsoever, because the technology is designed to facilitate internet browsing and other related activities, therefore, the featured podium cannot be used to advertise products as it will cause the user experience to diminish.' Seems like Google is going for hardware-only revenue on this one." You're not supposed to resell the Glass hardware, either.

U.S. Senate's Big Immigration Bill Seeks Centralized Database For H-1B Jobs 251

Posted by Soulskill
from the because-centralized-databases-are-always-a-good-idea dept.
dcblogs writes "The U.S. Senate comprehensive immigration bill, due Tuesday, will allow the H-1B cap to rise from 65,000 to as high as 180,000. The bill, overall, contains some interesting provisions. It will require the U.S. Labor Dept. to create a website of H-1B job openings that employers must post to. The jobs must be posted least 30 calendar days before hiring an H-1B applicant to fill that position. The bill also raises wages for H-1B workers to make them more competitive, although the amount wasn't specified. One provision that will affect India, in particular, limits H-1B visa use to 50% of a firm's U.S. workforce. The provision may prompt India firms to buy U.S. companies to expand their U.S. presence."

Google's BigQuery Vs. Hadoop: a Matchup 37

Posted by samzenpus
from the in-this-corner dept.
Nerval's Lobster writes "Ready to 'Analyze terabytes of data with just a click of a button?' That's the claim Google makes with its BigQuery platform. But is BigQuery really an analytics superstar? It was unveiled in Beta back in 2010, but recently gained some improvements such as the ability to do large joins. In the following piece, Jeff Cogswell compares BigQuery to some other analytics and OLAP tools, and hopefully that'll give some additional context to anyone who's thinking of using BigQuery or a similar platform for data. His conclusion? In the end, BigQuery is just another database. It can handle massive amounts of data, but so can Hadoop. It's not free, but neither is Hadoop once you factor in the cost of the hardware, support, and the paychecks of the people running it. The public version of BigQuery probably isn't even used by Google, which likely has something bigger and better that we'll see in five years or so."

Taking the Pain Out of Debugging With Live Programming 254

Posted by samzenpus
from the we'll-do-it-live dept.
angry tapir writes "'Everyone knows that debugging is twice as hard as writing a program in the first place,' Brian Kernighan once wrote (adding: 'So if you're as clever as you can be when you write it, how will you ever debug it?') However, Sean McDirmid, a researcher at Microsoft, has been working to remove some of the pain from debugging. McDirmid, based at Microsoft Research Asia, has been studying ways of implementing usable live programming environments: a solution that is less intrusive than classical debuggers. The idea is to essentially provide a programming environment in which editing of code and the execution of code occur simultaneously — and in the same interface as code editing — with tools to track the state of variables in a more or less live manner."
