Oracle Named Database of the Year, MongoDB Comes In Second (softpedia.com) 122

Posted by Soulskill from the headlines-from-a-parallel-universe dept.
An anonymous reader writes: Oracle's database management system has seen the biggest rise in terms of popularity in the past year. Oracle didn't only see a rise in the number of deployed instances, job offerings and mentions on LinkedIn profiles, but for the first time also became a popular topic on Twitter and a constant mention on StackOverflow, a popular Q&A support forum for developers. Second on DB-Engine's popularity list was MongoDB, which barely missed winning the DBMS of the Year award for the third time in a row.

K12CS.org: Microsoft, Google, Apple Identifying What 1st Graders Should Know 145

Posted by Soulskill from the how-to-get-mommy-and-daddy-to-buy-that-new-device dept.
theodp writes: On Sunday, The Simpsons declared computer coding class the nation's latest educational fad (script). Proving Principal Skinner's point, K12CS.org on Thursday announced a New Framework to Define K-12 Computer Science Education, the collaboration of participants from a number of states (MD, CA, IN, IA, AR, UT, ID, NE, GA, WA), large school districts (NYC, Chicago, San Francisco), technology companies (Microsoft, Google, Apple), organizations (Code.org, ACM, CSTA, ISTE, MassCAN, CSNYC), and individuals (higher ed faculty, researchers, K-12 teachers, and administrators). "A steering committee initially comprised of the Computer Science Teachers Association, the Association for Computing Machinery, and [tech bankrolled and led] Code.org will oversee this project," explained a CSTA blog post. "Funding for the project will be provided by Code.org and the ACM. The framework will identify key K-12 computer science concepts and practices we expect students exiting grades 2, 5, 8, and 12 to know."

In a FAQ, K12CS.org envisions a Programming and Algorithms standard for 1st Graders that calls for the 5-year-olds to "Work collaboratively in clear roles (e.g., pair programming) to construct a problem solution of a sequence of block-based programming commands." A day before the announcement, Politico reported that K-12 CS education is expected to get a State of the Union mention this year, and that the White House and U.S. Dept. of Education have been trolling for CS success stories in conjunction with the announcement of a broad set of new commitments to CS Education in early 2016.

Java Named Top Programming Language of 2015 (dice.com) 358

Posted by timothy from the because-of-the-taste dept.
Nerval's Lobster writes: What was the most popular programming language of 2015? According to the people behind the TIOBE Index, Java took that coveted spot, winning out over C, Python, PHP, and other languages. "At first sight, it might seem surprising that an old language like Java wins this award," read TIOBE's note accompanying the list. "Especially if you take into consideration that Java won the same award exactly 10 years ago." Yet Java remains essential not only for businesses, it continued, but also consumer-centric markets such as mobile development (i.e., Google Android). That being said, even big languages can tumble. (Dice link) Objective-C tumbled from third place to 18th in the past 12 months, thanks to Apple's decision to replace it with Swift. In 2016, TIOBE expects that "Java, PHP (with the new 7 release), JavaScript and Swift will be the top 10 winners for 2016. Scala might gain a permanent top 20 position, whereas Rust, Clojure, Julia and TypeScript will also move up considerably in the chart." What has been your most-used (or best-loved) programming language of the last 12 months?

PostgreSQL 9.5 Released 104

Posted by timothy from the once-in-a-while dept.
iamvego writes: Later than the typical release cadence, PostgreSQL 9.5 has finally been released, and brings with it a slew of new features including UPSERT functionality, row-level security, and some big data features (CUBE/ROLLUP, join pushdown for foreign data wrappers, TABLESAMPLE, BRIN indexing and more). The previous release had brought about some new JSON functions and operators, but they only queried the data; 9.5 comes with new operators which now allow modification of JSON values, so it no longer has to be manipulated outside of the database. PostgreSQL's wiki has a more detailed overview of the new features.

The Unsung Heroes of Scientific Software (nature.com) 62

Posted by Soulskill from the credit-where-credit-is-due dept.
An anonymous reader sends this news from Nature: For researchers who code, academic norms for tracking the value of their work seem grossly unfair. They can spend hours contributing to software that underpins research, but if that work does not result in the authorship of a research paper and accompanying citations, there is little way to measure its impact. ... Enter Depsy, a free website launched in November 2015 that aims to "measure the value of software that powers science."

[Postdoc researcher Klaus] Schliep's profile on that site shows that he has contributed in part to seven software packages, and that he shares 34% of the credit for phangorn. Those packages have together received more than 2,600 downloads, have been cited in 89 open-access research papers and have been heavily recycled for use in other software — putting Schliep in the 99th percentile of all coders on the site by impact.

Firefox Will Support Non-Standard CSS For WebKit Compatibility (theregister.co.uk) 132

Posted by samzenpus from the making-it-work dept.
RoccamOccam writes: Mozilla developers have discussed a plan to implement support for a subset of non-standard CSS prefixes used in WebKit. Mozilla developer Daniel Holbert says: "A good chunk of the web today (and particularly the mobile web) effectively relies on -webkit prefixed CSS properties & features. We wish we lived in a world where web content always included standards-based fallback (or at least multiple-vendor-prefixed fallback), but alas, we do not live in that world. To be successful at rendering the web as it exists, we need to add support for a list of frequently-used -webkit prefixed CSS properties & features."

Overcoming Intuition In Programming (amasad.me) 237

Posted by Soulskill from the learning-is-hard dept.
An anonymous reader writes: Amjad Masad, a programmer who works at Facebook, has put up a post about intuition and programming. It's based on a series of experiments (PDF) into how the presentation of a problem affects the learning involved in solving it. Researchers found that if they made a test deliberately hard to understand, those taking the test would exhibit greater understanding after solving it than those who were presented with a more intuitive wording of the same problem. Masad discusses how the research applies to software engineering: "Programming is an intellectually challenging task, but luckily we invent tools to make it manageable. I find that up to a certain point, the intuitive and easy properties of a given language, framework, or library might start to have negative effects.

From personal experience and from mentoring beginners I noticed that when using tools that allow us to reason within our intuition, anytime we're faced with some difficulty we feel that we've done something wrong. And although we might have the necessary skills to overcome the difficulty, we often start questioning and revising our work." He concludes, "Code reuse, libraries, sharing, and open-source are very important to software engineering, but we should be careful to not enable the belief that programming should be as easy as gluing things together."

The Sad Graph of Software Death (tinyletter.com) 210

Posted by Soulskill from the we'll-pull-it-into-the-next-sprint dept.
An anonymous reader writes: Programmers, raise your hand if you've been on a project where bugs keep piling up, management doesn't dedicate time to fix them, and the whole thing eventually bogs down. Gregory Brown summarizes that situation in one simple little graph from an issue tracker, and discusses why so many companies have problems with it. "This figure tells a story that is no way surprising to anyone who has worked on software projects before: demand for fixes and features is rapidly outpacing the supply of development time invested, and so the issue tracker is no longer serving as any sort of meaningful project planning tool. In all but the most well-funded, high functioning, and sustainable businesses — you can expect some degree of tension along these lines. The business side of the house may blame developers for not moving fast enough, while the developers blame the business for piling work on too quickly and not leaving time for cleanup, testing, and long-term investments. Typically, both sides have valid concerns, but they don't do an especially good job of communicating with one another." What methods have helped you deal with situations like this?

The Swift Programming Language's Most Commonly Rejected Changes (github.com) 339

Posted by Soulskill from the not-willing-to-force-every-function-to-be-recursive dept.
An anonymous reader writes: When Apple made its Swift programming language open source in early December, it opened the floodgates for suggestions and requests from developers. But the project's maintainers have their own ideas about how the language should evolve, so some suggestions are rejected. Now a list has been compiled of some commonly rejected proposals — it's an interesting window into the development of a language. Swift's developers don't want to replace Brace Syntax with Python-style indentation. They don't want to change boolean operators from && and || to 'and' and 'or'. They don't want to rewrite the Swift compiler in Swift. They don't want to change certain keywords like 'continue' from their C precedents. And they have no interest in removing semicolons.

Scott Meyers Retires From Involvement With C++ (blogspot.com) 112

Posted by Soulskill from the so-long,-and-thanks-for-all-the-best-practices dept.
An anonymous reader writes: If you've studied C++ any time in the past 25 years, you've probably read something by Scott Meyers. He wrote Effective C++, regarded by many as one of the top two books for learning to work with the language. He also wrote similar books about changes in C++11 and C++14, as well as making good use of the Standard Template Library. He's been a seemingly endless source of instructional videos, articles, and helpful answers on Usenet and StackOverflow. Unfortunately for us, Meyers has now decided to move on. "25 years after publication of my first academic papers involving C++, I'm retiring from active involvement with the language. It's a good time for it. My job is explaining C++ and how to use it, but the C++ explanation biz is bustling. ... My voice is dropping out, but a great chorus will continue." Thanks for all the help, Scott.

Open Source Roles: Starters vs. Maintainers (jlongster.com) 77

Posted by Soulskill from the boredom-vs-dedication dept.
An anonymous reader writes: Mozilla developer James Long has posted a sort of internal monologue on the difficulties of being a hobbyist open source project maintainer. He says, "I hugely admire people who give so much time to OSS projects for free. I can't believe how much unpaid boring work is going on. It's really cool that people care so much about helping others and the community. ... There are two roles for any project: starters and maintainers. People may play both roles in their lives, but for some reason I've found that for a single project it's usually different people. Starters are good at taking a big step in a different direction, and maintainers are good at being dedicated to keeping the code alive.

I am definitely a starter. I tend to be interested in a lot of various things, instead of dedicating myself to a few concentrated areas. I've maintained libraries for years, but it's always a huge source of guilt and late Friday nights to catch up on a backlog of issues. ... Here's to all the maintainers out there. To all the people putting in tireless, thankless work behind-the-scenes to keep code alive, to write documentation, to cut releases, to register domain names, and everything else."

Coding Styles Survive Binary Compilation, Could Lead Investigators Back To Programmers (princeton.edu) 164

Posted by Soulskill from the making-a-list-and-checking-it-twice dept.
An anonymous reader writes: Researchers have created an algorithm that can accurately detect code written by different programmers (PDF), even if the code has been compiled into an executable binary. Because of open source coding repositories like GitHub, state agencies can build a database of all developers and their coding styles, and then easily compare the coding style used in "anti-establishment" software to detect the culprit. Despite all the privacy implications this research may have, the algorithm can also be used by security researchers to track down malware authors. We also discussed an earlier phase of this research.

Some of the former tenants of Lakeview Apartments had leases through the end of the year, but were reportedly forced by owner Cypress Real Estate Advisors to move out early. Some have said their security deposits were not returned, and they have had no assistance as they've struggled to find comparably priced housing. Last week, some of those residents gathered near the site of their former home to protest and to appeal to Oracle for assistance.

Tech Segments Facing Turbulence In 2016 (dice.com) 72

Posted by timothy from the constant-change dept.
Nerval's Lobster writes: David Foote, an analyst who accurately predicted the tech industry's job growth in 2015, is back with some new predictions about which segments will do well in 2016 (Dice link). At the top of his list: DevOps, cloud and software architects, and cybersecurity experts. Those that won't perform well? SAP specialists, storage 'gurus,' and network managers could all face some headwinds. 'Companies are continuing to outsource infrastructure and that will reduce the need for network specialists except for network security which will remain in-house,' he says. Whether or not he's right about which parts of the tech industry will do better than others, there are also increasing signs that things could get very tight from a funding perspective for startups, as even the so-called 'unicorns' risk seeing investor money (and customers) dry up.

US Dept. of Ed: English, History, and Civics Teachers Good Enough For CS Class 242

Posted by samzenpus from the close-enough dept.
theodp writes: In A New Chapter for Computer Science Education, the U.S. Department of Education explained earlier this month that the federal STEM Education Act of 2015 'provides an unprecedented opportunity to fully leverage federal resources' to address large gaps in students' participation in Advanced Placement (AP) computer science classes based on gender and race. "In three states," lamented the DOE, "not a single female student took the AP computer science exam" (that only 8 boys took the AP CS exam in those same 3 states was apparently not a concern). And the DOE has good news for those hoping to tap Title I and II funds for CS, but don't have any computer science teachers. "A background in math or science isn't necessarily a requirement to teach CS," explains the Dept. of Ed, "as disciplines like English, history and civics can also provide a solid foundation for teaching CS concepts."

Apps are also a lot of work for developers—it's not easy to write native apps to run on both Android and iOS, never mind considering Windows Phone and BlackBerry. What's the alternative? Well, perhaps the best answer is to go back to the future and do what we do on desktop computers: use the Web and the Web browser.

Fixing JavaScript's Broken Random Number Generator (hackaday.com) 136

Posted by samzenpus from the the-fix-is-in dept.
szczys writes: It is surprising to learn how broken the JavaScript Random Number Generator has been for the past six years. The problem is compounded by the fact that Node.js uses the same broken Math.random() module. Learning about why this is broken is interesting, but perhaps even more interesting is how the bad code got there in the first place. It seems that a forum thread from way back in 1999 shared two versions of the code. If you read to the end of the thread you got the working version, if you didn't make it that far (perhaps the case with JavaScript devs) you got the bad version of the code whose fix is just now being rolled out.
