Kotlin, which Google blessed last year as an alternative to Java for programming Android apps, has already made its way into almost 12 per cent of open source Android apps, and in so doing has elevated their code quality. From a report: So we're told by computer scientists Bruno Gois Mateus and Matias Martinez, affiliated with University of Valenciennes in France, who observed that Google at the end of 2017 said Kotlin had infiltrated more than 17 per cent of Android apps developed with its IDE, Android Studio 3.0. Kotlin is an open source statically typed programing language that targets the JVM, Android, JavaScript (transpiling to ES5.1) and native platforms (via LLVM). JetBrains, the company that created it, contends Kotlin is more concise and more type-safe than Java. It estimates that apps written in Kotlin require about 40 per cent less code than they would with Java. With fewer lines of code, in theory, one can expect fewer bugs. In a paper distributed through pre-print service ArXiv, "An Empirical Study on Quality of Android Applications written in Kotlin language," Mateus and Martinez describe how they gathered 925 apps from the open source F-Droid repository, measured the amount of Kotlin code in each, and analyzed the code for "smells" as an indicator of code quality.

An anonymous reader quotes IEEE Spectrum: [W]hat's so compelling about RISC-V isn't the technology -- it's the economics. The instruction set is open source. Anyone can download it and design a chip based on the architecture without paying a fee. If you wanted to do that with ARM, you'd have to pay its developer, Arm Holding, a few million dollars for a license. If you wanted to use x86, you're out of luck because Intel licenses its instruction set only to Advanced Micro Devices. For manufacturers, the open-source approach could lower the risks associated with building custom chips.

Already, Nvidia and Western Digital Corp. have decided to use RISC-V in their own internally developed silicon. Western Digital's chief technology officer has said that in 2019 or 2020, the company will unveil a new RISC-V processor for the more than 1 billion cores the storage firm ships each year. Likewise, Nvidia is using RISC-V for a governing microcontroller that it places on the board to manage its massively multicore graphics processors.

An anonymous reader shares a blog post on OpenSourceMap: Most OSM commentary focuses on unimportant minutiae (layers, for goodness' sake, as if it's still 2004) without seeking to examine what makes OSM unique -- and whether that's still relevant in a rapidly changing market. Could OSM become a dead-end curio while Google, Apple, and an increasingly self-sufficient Mapbox hare off in another, common direction? OSM's continuing differentiation from Google/Apple boils down to two points.

First, a non-commercial imperative. Google and Apple (and Mapbox, TomTom, HERE) are beholden to their shareholders and investors. They do what makes them money, which means car navigation. (Once human-controlled, now, increasingly, self-guided. When people ask "How far ahead of Apple is Google Maps?", what they usually mean is "Who will get to self-driving cars first?") OSM, however, isn't ruled by shareholder value, but by the preoccupations of its contributor base. (We'll come onto that demographic later.) Whether that's a good thing depends on what you want from a map. But it's clearly a point of differentation.

Second, ground truthed local knowledge. Surveying by locals is the gold standard of OSM, building a rich, intricate compilation of contributors' preoccupations. The painstaking human curation of areas and topics remains unique to OSM. Neither of these are under threat from Google/Apple. Outsourced quick-fire digitisation of Street View-type imagery in cheap labour countries doesn't give you this. Nor does image recognition. OSM's points of differentation remain clear. In OSM's early days, commentators used the phrase "democratising mapmaking," and it remains true. You choose what to map; and you choose how to use the map. You participate. Other maps are a one-way street: sure, you can contribute (actively through map corrections, or passively through using a mobile app that phones home), but the provider chooses what you get back.

BrianFagioli shares a report from BetaNews: Microsoft seems eager to get programmers on the quantum bandwagon, as today, it launched the open-source Quantum Katas on GitHub. What exactly is it? It is essentially a project deigned to teach Q# programming for free. "For those who want to explore quantum computing and learn the Q# programming language at their own pace, we have created the Quantum Katas -- an open-source project containing a series of programming exercises that provide immediate feedback as you progress," says The Microsoft Quantum Team. "Coding katas are great tools for learning a programming language. They rely on several simple learning principles: active learning, incremental complexity growth, and feedback."

The team further says, "The Microsoft Quantum Katas are a series of self-paced tutorials aimed at teaching elements of quantum computing and Q# programming at the same time. Each kata offers a sequence of tasks on a certain quantum computing topic, progressing from simple to challenging. Each task requires you to fill in some code; the first task might require just one line, and the last one might require a sizable fragment of code. A testing framework validates your solutions, providing real-time feedback." You can view the project on GitHub here.

Slashdot reader fisted quotes NetBSD.org: The NetBSD Project is pleased to announce NetBSD 8.0, the sixteenth major release of the NetBSD operating system.

This release brings stability improvements, hundreds of bug fixes, and many new features. Some highlights of the NetBSD 8.0 release are:

— USB stack rework, USB3 support added.
— In-kernel audio mixer (audio_system(9)).
— Reproducible builds
— PaX MPROTECT (W^X) memory protection enforced by default
— PaX ASLR enabled by default
— Position independent executables by default
[...]

NetBSD is free. All of the code is under non-restrictive licenses, and may be used without paying royalties to anyone.

A crowdfunded project, known as "PeerTube," has blown through its initial goal with 53,100 euros collected in forty-two days. The project aims to be "a fully decentralized version of YouTube, whose computer code is freely accessible and editable, and where videos are shared between users without relying on a central system." The goal is PeerTube to officially launch by October. Quariety reports: PeerTube relies on a decentralized and federative system. In other words, there is no higher authority that manages, broadcasts and moderates the content offered, as is the case with YouTube, but a network of "instances." Created by one or more administrators, these communities are governed according to principles specific to each of them. Anyone can freely watch the videos without registering, but to upload a video, you must choose from the list of existing instances, or create your own if you have the necessary technical knowledge. At the moment, 141 instances are proposed. Most do not have specifics, but one can find communities centered on a theme or open to a particular region of the world. In all, more than 4,000 people are currently registered on PeerTube, for a total of 338,000 views for 11,000 videos. The project does not display ads, unlike YouTube. "In terms of monetization, we wanted to make a neutral tool," says Pouhiou, communication officer for Framasoft, the origin of PeerTube. The site will rely on a "support" button at the start, but "people will be able to code their own monetization system" in the future.

Christine Peterson is a long-time futurist who co-founded the nanotech advocacy group the Foresight Institute in 1986. One of her favorite tasks has been contacting the winners of the institute's annual Feynman Prize in Nanotechnology, but she also coined the term "Open Source software" for that famous promotion strategy meeting in 1998.

Christine took some time to answer questions from Slashdot readers.

Government Technology reports: On July 16, Google Maps is going to make it more difficult and expensive to use its API, which could make custom maps that rely on the service less sustainable or even unfeasible for the people who made them... First, Google Maps is requiring all projects to have an official API key in order to work. If a user doesn't have a key, the quality of the map will likely be reduced, or it could simply stop working. Second, API keys will only work if they are attached to somebody's credit card. Google will charge that card if users exceed a certain number of API requests, which is different for different services. Google will provide users a free $200 credit toward those costs each month...

There are a couple places where the changes might have more of an impact. One is in the civic hacking space, where people often work with government data to create niche projects that aim for low costs, or are free so that as many people as possible can use them... "I think that's what scares people a little bit, it certainly scares me, this thought of having this API out there and not knowing how many people are going to use it," said Derek Eder, founder of the civic tech company DataMade. "I don't want to suddenly get a bill for $1,000."
There's at least three Open Source alternatives, and Geoawesomeness.com lists nine more.

Slashdot reader Jiri_Komarek also points out that Google's move was good news for its competitor, MapTiler. "Since Google announced the pricing change the number of our users increased by 200%," said Petr Pridal, head of the MapTiler team. "We expect more people to come as they get their first bill from Google."

Sean Michael Kerner, writing for eSecurity Planet: Back in 1999, Eric Raymond coined the term "Linus' Law," which stipulates that given enough eyeballs, all bugs are shallow. Linus' Law, named in honor of Linux creator Linus Torvalds, has for nearly two decades been used by some as a doctrine to explain why open source software should have better security. In recent years, open source projects and code have experienced multiple security issues, but does that mean Linus' Law isn't valid?

According to Dirk Hohndel, VP and Chief Open Source Officer at VMware, Linus' Law still works, but there are larger software development issues that impact both open source as well as closed source code that are of equal or greater importance. "I think that in every development model, security is always a challenge," Hohndel said. Hohndel said developers are typically motivated by innovation and figuring out how to make something work, and security isn't always the priority that it should be. "I think security is not something we should think of as an open source versus closed source concept, but as an industry," Hohndel said.

"The GNOME Foundation is pleased to be able to offer paid employment to exceptional people who have the drive to help us complete our mission," reads a new announcement. Gnome.org explains: Today, July 6th 2018, the GNOME Foundation has announced a number of positions it is recruiting for to help drive the GNOME project and Free Software on the desktop.

As previously announced, this has been made possible thanks to a generous grant that the Foundation has received, enabling us to accelerate this expansion. "These positions are key to ensuring that the Foundation remains sustainable and that we are able to support the community in key areas," said Neil McGovern, Executive Director of the GNOME Foundation.
The Foundation is currently recruiting for four posts:

• Development Coordinator. This will ensure that we receive sufficient funds to continue our work delivering free software.
• Program Coordinator. The Program Coordinator will free up time from those involved in organizational, administrative and logistical problems.
• Devops/Sysadmin. The systems and services we run need proper maintenance and care. As Flathub [An app store and build service for Linux] continues to grow, more support is needed to achieve this.
• GTK+ core developer. GTK+ is core to our entire platform. Investing in development and maintenance of this toolkit will benefit the whole GNU/Linux ecosystem.

"The Foundation is keen to hear from any person who is interested in applying for one of these posts."

An anonymous reader quotes a report from MSPoweruser: Today, Microsoft announced that it is releasing 124 Million building footprints in the United States to the OpenStreetMap community. Bing Maps team used Microsoft's CNTK Unified Toolkit to apply its Deep Neural Networks and the ResNet34 with RefineNet up-sampling layers to detect building footprints from the Bing imagery. OpenStreetMap currently has 30,567,953 building footprints in the U.S., thanks to editor contributions and various city or county wide imports. Using DNNs and Bing Imagery, Microsoft has extracted 124,885,597 footprints in the United States and making it available for download free of charge.

Steven J. Vaughan-Nichols, writing for ZDNet: Google couldn't exist without Linux and open-source software. While you may not think of Google as a Linux company in the same way as you do Canonical, Red Hat, or SUSE, it wouldn't be the search and advertising giant it is today without Linux. So, it makes sense that Google is moving up from its Silver membership in The Linux Foundation, to the Platinum level. With this jump in status, Google gets a seat on the Foundation's board of directors. This position will be filled by Sarah Novotny, the head of open source strategy for Google Cloud Platform. Earlier this week, Chinese tech giant Tencent joined the Linux Foundation as a platinum member.

"Open source maintainers are exhausted and rarely paid," writes TechCrunch's editorial manager. "A new generation wants to change the economics."

An anonymous reader quotes their report: [Patreon] is increasingly being used by notable open source contributors as a way to connect with fans and sustain their work... For those who hit it big, the revenues can be outsized. Evan You, who created the popular JavaScript frontend library Vue.js, has reached $15,206 in monthly earnings ($182,472 a year) from 231 patrons... While Patreon is one direct approach for generating revenues from users, another one is to offer dual licenses, one free and one commercial... Companies care about proper licensing, and that becomes the leverage to gain revenue while still maintaining the openness and spirit of open source software...

Tidelift is designed to offer assurances "around areas like security, licensing, and maintenance of software," CEO Donald Fischer explained... In addition, Tidelift handles the mundane tasks of setting up open source for commercialization such as handling licensing issues... Open Collective wants to open source the monetization of open source itself. Open Collective is a non-profit platform that provides tools to "collectives" to receive money while also offering mechanisms to allow the members of those collectives to spend their money in a democratic and transparent way.
TechCrunch warns that "It's not just that people are free riding, it's often that they don't even realize it. Software engineers can easily forget just how much craftsmanship has gone into the open source code that powers the most basic of applications...

"If you work at a for-profit company, take the lead in finding a way to support the code that allows you to do your job so efficiently. The decentralization and volunteer spirit of the open source community needs exactly the same kind of decentralized spirit in every financial contributor. Sustainability is each of our jobs, every day."

An anonymous reader quotes ZDNet: When leading Linux company Red Hat announces that -- from here on out -- all new Red Hat-initiated open-source projects that use the GNU General Public License (GPLv2) or GNU Lesser General Public License (LGPL) v2.1 licenses will be expected to supplement the license with GPL version 3 (GPLv3)'s cure commitment language, it's a big deal. Both older open-source licenses are widely used.

When the GPLv3 was released, it came with an express termination approach that offered developers the chance to cure license compliance errors. This termination policy in GPLv3 provided a way for companies to repair licensing errors and mistakes... Other companies -- CA Technologies, Cisco, HPE, Microsoft, SAP, and SUSE -- have taken similar GPL positions... In its new position statement, Red Hat explained that the GPLv2 and LGPL, as written, has led to the belief that automatic license termination and copyright infringement claims can result from a single act of inadvertent non-compliance.
"We hope that others will also join in this endeavor," says Red Hat's senior commercial counsel, Richard Fontana, "to reassure the open source community that good faith efforts to fix noncompliance will be embraced."

ZDNet points out that the move to new licenses "doesn't apply, of course, to Linux itself. Linus Torvalds has made it abundantly clear that Linux has been, will now, and always shall be under the GPLv2."

Bruce Perens co-founded the Open Source Initiative with Eric Raymond -- and he's also Slashdot reader #3872. Now he's just won a legal victory in court. "Open Source Security, maker of the grsecurity Linux kernel patches, has been directed to pay Bruce Perens and his legal team almost $260,000 following a failed defamation claim," reports The Register. Slashdot reader Right to Opine writes: The order requires Spengler and his company to pay $259,900.50, with the bill due immediately rather than allowing a wait for the appeal of the case. The Electronic Frontier Foundation's attorneys will represent Perens during OSS/Spengler's appeal of the case.

Perens was sued for comments on his blog and here on Slashdot that suggested that OSS's Grsecurity product could be in violation of the GPL license on the Linux kernel. The court had previously ruled that Perens' statements were not defamatory, because they were statements by a non-attorney regarding an undecided issue in law. It is possible that Spengler is personally liable for any damages his small company can't pay, since he joined the case as an individual in order to preserve a claim of false light (which could not be brought by his company), removing his own corporate protection.

"Despite its low profile, OpenStreetMap is arguably one of the most important projects for the future of free software," argues Glyn Moody, author of Rebel Code: Linux And The Open Source Revolution, in a new Linux Journal article shared by long-time Slashdot reader carlie: The rise of mobile phones as the primary computing device for billions of people, especially in developing economies, lends a new importance to location and movement. Many internet services now offer additional features based on where users are, where they are going and their relative position to other members of social networks. Self-driving cars and drones are two rapidly evolving hardware areas where accurate geographical information is crucial. All of those things depend upon a map in critical ways, and they require large, detailed datasets. OpenStreetMap is the only truly global open alternative to better-known, and much better-funded geodata holdings, such as Google Maps.

The current dominance of the latter is a serious problem for free software -- and freedom itself. The data that lies behind Google Maps is proprietary. Thus, any open-source program that uses Google Maps or other commercial mapping services is effectively including proprietary elements in its code. For purists, that is unacceptable in itself. But even for those with a more pragmatic viewpoint, it means that open source is dependent on a company for data that can be restricted or withdrawn at any moment....

Although undoubtedly difficult, creating high-quality map-based services is a challenge that must be tackled by the Open Source community if it wants to remain relevant in a world dominated by mobile computing. The bad news is that at the moment, millions of people are happily sending crucial geodata to proprietary services like Waze, as well as providing free bug-fixes for Google Maps. Far better if they could be working with equal enthusiasm and enjoyment on open projects, since the resulting datasets would be freely available to all, not turned into corporate property. The good news is that OpenStreetMap provides exactly the right foundation for creating those open map-based services, which is why supporting it must become a priority for the Open Source world.
