Android Now Supports the Kotlin Programming Language ( 91

In addition to Java and C++, Google announced at its I/O 2017 conference today that Android is gaining official support for the Kotlin programming language. VentureBeat reports: Kotlin is developed by JetBrains, the same people who created IntelliJ. Google describes Kotlin, which is an open sourced project under the Apache 2.0 license, as "a brilliantly designed, mature language that we believe will make Android development faster and more fun." The company notes that some have already adopted the programming language for their production apps, including Expedia, Flipboard, Pinterest, and Square. There are already many enthusiastic Kotlin developers for Android, and the company says it is simply listening to what the community wants. But Google's choice didn't just come down to the team believing Kotlin will make writing Android apps easier. Developers will be happy to know that Kotlin's compiler emits Java byte-code. Kotlin can call Java, and Java can call Kotlin. Indeed, "the effortless interoperation between the two languages" was a large part of Kotlin's appeal to the Android team. This means you can add as little or as much Kotlin into your existing codebase as you want, mixing the two languages freely within the same project. Calling out to Kotlin code from Java code should just work, while calling to Java code requires some automatically applied translation conventions.

Developer Creates An Experimental Perl 5 To Java Compiler ( 94

An anonymous reader writes: Saturday night saw the announcement of an experimental Perl 5 to Java compiler. "This is the first release," posted developer FlÃvio S. Glock -- after 100 weeks of development. "Note that you don't need to compile a Java file. Perlito5 now compiles the Perl code to JVM bytecode in memory and executes it." He describes the compiler as "a work-in-progress" that "provides an impressive coverage of Perl features, but it will not run most existing Perl programs due to platform differences."

Open Source SQL Database CockroachDB Hits 1.0 ( 80

An anonymous reader quotes InfoWorld: CockroachDB, an open source, fault-tolerant SQL database with horizontal scaling and strong consistency across nodes -- and a name few people will likely forget -- is now officially available. Cockroach Labs, the company behind its development, touts CockroachDB as a "cloud native" database solution -- a system engineered to run as a distributed resource. Version 1.0 is available in both basic and for-pay editions, and both boast features that will appeal to enterprises.

The company is rolling the dice with its handling of the enterprise edition by also making those components open source and trusting that enterprises will pay for what they use in production.


Microsoft Is Surprisingly Comfortable With Its New Place In a Mobile, Apple, and Android World ( 73

An anonymous reader writes: The company that once held a mock funeral for the iPhone -- complete with dedicated "iPhone trashcans" -- now has a very different attitude about the company of Jobs. The Microsoft whose old CEO Steve Ballmer in 2007 famously predicted the iPhone had "no chance; no chance at all" of getting market share, now readily accepts and embraces a world where the iPhone and Android dominate personal computing. Microsoft talked a lot here at its Build 2017 developer conference about extending Windows experiences over to iOS and Android devices. And it's not just about fortifying Windows. Microsoft says it not only wants to connect with those foreign operating systems, but by bringing over functionality from Windows 10 (along with content) it hopes to "make those other devices better," as one Microsoft rep said in a press briefing yesterday. The developers here at Build cheered when Microsoft announced XAML Standard 1.0, which provides a single markup language to make user interfaces that work on Windows, iOS, and Android. In one demo, the company demonstrated how an enterprise sales app could be extended to an iOS device so someone could continue capturing a potential client's data on a mobile device. Windows not only sent over the client data that had already been captured, but also the business-app shell that had captured it.

Apple is Bringing iTunes To the Windows Store ( 87

Tom Warren, writing for The Verge: Apple is planning to bring its iTunes desktop app to the Windows Store. In a surprise announcement at the Build developer event today, Microsoft revealed it has been working with Apple to get iTunes listed in the Windows Store. It might not sound like an important addition, but iTunes is one of the most searched for apps that's currently missing in the Windows Store. USA Today veteran columnist, summing up the announcement, "Microsoft announces that iTunes (incl Apple Music and full support for iPhone) is coming to the Windows Store. Big get for Microsoft." Microsoft's communication head, summing up the situation, "Didn't see that one coming, did you!"

Azure Goes Database Crazy With One New NoSQL, Two New SQL Services ( 39

An anonymous reader quotes a report from Ars Technica: In its continued efforts to make Azure a platform that appeals to the widest range of developers possible, Microsoft announced a range of new features at Build, its annual developer conference. Many of the features shown today had a data theme to them. The most novel feature was the release of Cosmos DB, a replacement for, or upgrade to, Microsoft's Document DB NoSQL database. Cosmos DB is designed for "planet-scale" applications, giving developers fine control over the replication policies and reliability. Replicated, distributed systems offer trade-offs between latency and consistency; systems with strong consistency wait until data is fully replicated before a write is deemed to be complete, which offers consistency at the expense of latency. Systems with eventual consistency mark operations as complete before data is fully replicated, promising only that the full replication will occur eventually. This improves latency but risks delivering stale data to applications. Document DB offered four different options for the replication behavior; Cosmos DB ups that to five. The database scales to span multiple regions, with Microsoft offering service level agreements (SLAs) for uptime, performance, latency, and consistency. There are financial penalties if Microsoft misses the SLA requirements. Many applications still call for traditional relational databases. For those, Microsoft is adding both a MySQL and a PostgreSQL service; these provide the familiar open source databases in a platform-as-a-service style, removing the administrative overhead that comes of using them and making it easier to move workloads using them into Azure. The company is also offering a preview of a database-migration service that takes data from on-premises SQL Server and Oracle databases and migrates it to Azure SQL Database. Azure SQL Database has a new feature in preview called "Managed Instances" that offers greater compatibility between on-premises SQL Server and the cloud variant, again to make workload migration easier.

Only 36 Percent of Indian Engineers Can Write Compilable Code, Says Study ( 210

New submitter troublemaker_23 quotes a report from ITWire: Only 36% of software engineers in India can write compilable code based on measurements by an automated tool that is used across the world, the Indian skills assessment company Aspiring Minds says in a report. The report is based on a sample of 36,800 from more than 500 colleges across India. Aspiring Minds said it used the automated tool Automata which is a 60-minute test taken in a compiler integrated environment and rates candidates on programming ability, programming practices, run-time complexity and test case coverage. It uses advanced artificial intelligence technology to automatically grade programming skills. "We find that out of the two problems given per candidate, only 14% engineers are able to write compilable codes for both and only 22% write compilable code for exactly one problem," the study said. It further found that of the test subjects only 14.67% were employable by an IT services company. When it came to writing fully functional code using the best practices for efficiency and writing, only 2.21% of the engineers studied made the grade.

An anonymous reader writes: Earlier today, Tim Sweeney, the founder of Epic Games, asked his Twitter followers an interesting question: "What are the attributes of an ideal programming language if computers were infinitely fast, and we designed for coding productivity only?" I could think of several things, the chief of which would be getting rid of the garbage collection. I was wondering what other things you folks would suggest?

Oracle And Cisco Both Support The FCC's Rollback Of Net Neutrality ( 136

An anonymous reader quotes The Hill: Oracle voiced support on Friday for FCC Chairman Ajit Pai's controversial plan to roll back the agency's net neutrality rules. In a letter addressed to the FCC, the company played up its "perspective as a Silicon Valley technology company," hammering the debate over the rules as a "highly political hyperbolic battle," that is "removed from technical, economic, and consumer reality"... Oracle wrote in their letter [PDF] that they believe Pai's plan to remove broadband providers from the FCC's regulatory jurisdiction "will eliminate unnecessary burdens on, and competitive imbalances for, ISPs [internet service providers] while enhancing the consumer experience and driving investment"... Other companies in support of Pai's plan, like AT&T and Verizon, have made the argument that the rules stifled investment in the telecommunications sector, specifically in broadband infrastructure.
Cisco has also argued that strict net neutrality laws on ISPs "restrict their ability to use innovative network management technology, provide appropriate levels of quality of service, and deliver new features and services to meet evolving consumer needs. Cisco believes that allowing the development of differentiated broadband products, with different service and content offerings, will enhance the broadband market for consumers."

Should The Government Pay For Veterans To Attend Code Schools? ( 168

mirandakatz writes: David Molina was finishing up his 12-year time in the army when he started teaching himself to code, and started to think that he might like to pursue it professionally once his service was done. But with a wife and family, he couldn't dedicate the four years he'd need to get an undergraduate degree in computer science -- and the GI Bill, he learned, won't cover accelerated programs like code schools. So he started an organization dedicated to changing that. Operation Code is lobbying politicians to allow vets to attend code schools through the GI Bill and prepare themselves for the sorts of stable, middle-class jobs that have come to be called "blue-collar coding." Molina sees it as a serious failing that the GI Bill will cover myriad vocational programs, but not those that can prepare veterans for one of the fastest-growing industries in existence.
The issue seems to be quality. The group estimates there are already nine code schools in the U.S. which do accept GI Bill benefits -- but only "longer-standing ones that have made it through State Approving Agencies." Meanwhile, Course Report calculates 18,000 people finished coding bootcamps last year -- and that two thirds of them found a job within three months.

But I just liked how Molina described his introduction into the world of programmers. While stationed at Dover Air Force Base, he attended Baltimore's long-standing Meetup for Ruby on Rails, where "People taught me about open source. There was pizza, there was beer. They made me feel like I was at home."

Red Hat And IBM Will Vote Against Java's Next Release ( 57

An anonymous reader quotes InfoWorld: The next edition of standard Java had been proceeding toward its planned July 27 release after earlier bumps in the road over modularity. But now Red Hat and IBM have opposed the module plan. "JDK 9 might be held up by this," Oracle's Georges Saab, vice president of development for the Java platform, said late Wednesday afternoon. "As is the case for all major Java SE releases, feedback from the Java Community Process may affect the timeline..."

Red Hat's Scott Stark, vice president of architecture for the company's JBoss group, expressed a number of concerns about how applications would work with the module system and its potential impact on the planned Java Enterprise Edition 9. Stark also said the module system, which is featured in Java Specification Request 376 and Project Jigsaw, could result in two worlds of Java: one for Jigsaw and one for everything else, including Java SE classloaders and OSGI. Stark's analysis received input from others in the Java community, including Sonatype.

"The result will be a weakened Java ecosystem at a time when rapid change is occurring in the server space with increasing use of languages like Go," Stark wrote, also predicting major challenges for applications dealing with services and reflection. His critique adds that "In some cases the implementation...contradicts years of modular application deployment best practices that are already commonly employed by the ecosystem as a whole." And he ultimately concludes that this effort to modularize Java has limitations which "almost certainly prevent the possibility of Java EE 9 from being based on Jigsaw, as to do so would require existing Java EE vendors to completely throw out compatibility, interoperability, and feature parity with past versions of the Java EE specification."

In Oracle's Cloud Pitch To Enterprises, an Echo of a Bygone Tech Era ( 55

An anonymous reader writes: Oracle sought to position itself once again this week as the best place for everything companies need to move to cloud computing. On Thursday, executives at the database and business software giant distanced Oracle from public cloud leaders such as Amazon Web Services, Google Cloud Platform and Microsoft Azure that provide computing, storage and other services to corporations looking to reduce or eliminate their data centers. "Our cloud is more comprehensive than any other cloud in the market today, a full end-to-end cloud," said David Donatelli, Oracle's executive vice president of converged infrastructure. "We design from the chip all the way up to the application, fully vertically integrated." What's interesting about that messaging, which Oracle has been refining since at least its OpenWorld conference last September, is not simply the competitive positioning. Oracle is essentially saying that the nature of cloud computing suggests customers need to move away from the notion that has dominated information technology since personal computers and PC-based servers began to displace mainframes and minicomputers: cherry-picking the best applications and hardware and cobbling together their own IT setups. In short, Oracle contends, it's time for another broad swing back to the integrated, uber-suppliers of a bygone era of technology. Of course, the new tech titans such as Google, Facebook and Amazon arguably wield as much power in their particular domains of advertising and e-commerce as the Big Blue of old. But it has been a long time since a soup-to-nuts approach has worked for enterprise tech companies, and for those few still attempting it, such as Dell and Oracle, it's far from obvious it will work. The cloud, Oracle contends, may well change that.

How Scratch Is Feeding Hacker Values into Young Minds ( 48

Reader mirandakatz writes: It's the 10th anniversary of Scratch, the kids programming language that's become a popular tool for training the next generation of minds in computer science. But as Steven Levy writes at Backchannel, Scratch's real value is how it imparts lessons in sharing, logic, and hackerism: 'A product of the MIT Media Lab, Scratch is steeped in a complicated set of traditions -- everything from educational philosophy to open source activism and the pursuit of artificial life. The underpinnings of this tool subtly, and sometimes not so subtly, convey a set of values through its use... These values include reverence of logic, an unshakeable belief in the power of collaboration, and a celebration of the psychic and tangible rewards of being a maker.'

NASA Runs Competition To Help Make Old Fortran Code Faster ( 205

NASA is seeking help from coders to speed up the software it uses to design experimental aircraft. From a report on BBC: It is running a competition that will share $55,000 between the top two people who can make its FUN3D software run up to 10,000 times faster. The FUN3D code is used to model how air flows around simulated aircraft in a supercomputer. The software was developed in the 1980s and is written in an older computer programming language called Fortran. "This is the ultimate 'geek' dream assignment," said Doug Rohn, head of NASA's transformative aeronautics concepts program that makes heavy use of the FUN3D code. In a statement, Mr Rohn said the software is used on the agency's Pleiades supercomputer to test early designs of futuristic aircraft. The software suite tests them using computational fluid dynamics, which make heavy use of complicated mathematical formulae and data structures to see how well the designs work.

China Makes Quantum Leap In Developing Quantum Computer ( 70

hackingbear writes: Researchers at the University of Science and Technology of China created a quantum device, called a boson sampling machine, that can now carry out calculations for five photons, but at a speed 24,000 times faster than previous experiments. Pan Jianwei, the lead scientist on the project, said that though their device was already (only) 10 to 11 times faster at carrying out the calculations than the first electronic digital computer, ENIAC, and the first transistor computer, TRADIC, in running the classical algorithm, their machine would eclipse all of the world's supercomputers in a few years. "Our architecture is feasible to be scaled up to a larger number of photons and with a higher rate to race against increasingly advanced classical computers," they said in the research paper published in Nature Photonics. This device is said to be the first quantum computer beating a real electronic classical computer in practice. Scientists estimate that the current faster supercomputers would struggle to estimate the behavior of 20 photons.
