Programming languages can be hard to grasp for non-English speakers. Step forward, Bato: A Ruby port for Filipinos

TuxMachines - Thu, 2018-03-22 16:17

A Filipino developer is hoping his handmade Ruby port will help bring coding skills to some of the Philippines's poorest communities.

Joel Bryan Juliano says he built Bato as a way for speakers of Tagalog – the most widely-spoken language in the nation – to be able to learn the basics of programming without also having to be fluent in English. Today's coding languages tend to be built around English grammar, which is a problem for people without a grasp on English.

A software engineer with Altus Digital Capital by day, Juliano told The Register he developed Bato as an educational tool for skilling up family members, and quickly saw how it could be used to show the basics of programming without language barriers.

FOSS Licensing: Good Compliance Practices and "Do I Have to Use a Free/Open Source License?"

TuxMachines - Thu, 2018-03-22 16:13
  • Good Compliance Practices Are Good Engineering Practices

    Companies across all industries use, participate in, and contribute to open source projects, and open source compliance is an integral part of the use and development of any open source software. It’s particularly important to get compliance right when your company is considering a merger or acquisition. The key, according to Ibrahim Haddad, is knowing what’s in your code, right down to the exact versions of the open source components.

  • Do I Have to Use a Free/Open Source License?

    That, as we all probably already know, is not the case. The only licenses that can be called "open source" are those that are reviewed and approved as such by the Open Source Initiative (aka OSI). Its list of OSI-Approved licenses allows developers to choose and apply a license without having to hire a lawyer. It also means that companies no longer need to have their own lawyers review every single license in every piece of software they use. Can you imagine how expensive it would be if every company needed to do this? Aside from the legal costs, the duplication of effort alone would lead to millions of dollars in lost productivity. While the OSI's other outreach and advocacy efforts are important, there's no doubt that its license approval process is a service that provides an outsized amount of value for developers and companies alike.

Programming/Development: JupyterLab, Python Enhancement Proposal (PEP), Rust, Python 3.7 in Fedora

TuxMachines - Thu, 2018-03-22 16:11
  • JupyterLab: ready for users

    In the recent article about Jupyter and its notebooks, we mentioned that a new interface, called JupyterLab, existed in what its developers described as an "early preview" stage. About two weeks after that article appeared, Project Jupyter made a significant announcement: JupyterLab is "ready for users". Users will find a more integrated environment for scientific computation that is also more easily extended. JupyterLab takes the Jupyter Notebook to a level of functionality that will propel it well into the next decade—and beyond.

    While JupyterLab is still in beta, it is stable and functional enough to be used in daily work, and steadily approaching a 1.0 release. From the point of view of developers working on extensions or other projects that use the JupyterLab API, however, the beta status serves as a caution that its developer interfaces are still in flux; they should plan for the possibility of breaking changes.

    JupyterLab arose in 2015 from the desire to incorporate the "classic" (as it is known now) Jupyter Notebook into something more like an integrated development environment running in the browser. In addition, the user was to have the ability to extend the environment by creating new components that could interact with each other and with the existing ones. The 2011 web technology that the Jupyter Notebook was built upon was not quite up to this task. Although existing JavaScript libraries, such as React, suggested a way forward, none of them had the power and flexibility, particularly in the area of interprocess communication, that was required. The JupyterLab team addressed this problem by developing a new JavaScript framework called PhosphorJS. JupyterLab and PhosphorJS are co-developed, with capabilities added to the JavaScript framework as they are needed for JupyterLab.


    The Jupyter Notebook has already won over many scientists and educators because of the ease with which it allows one to explore, experiment, and share. JupyterLab makes the Notebook part of a more complete, powerful, and extensible environment for pursuing computational science and disseminating the results, leaving little doubt that this free-software project will win over an even larger portion of the scientific community. I've tried to give some idea of the power and convenience of the JupyterLab interface, but to really appreciate this technology, you need to try it out yourself. Fortunately, this is easy to do, as it's simple to install and intuitive enough to get started without reading documentation—and it happens to be a great deal of fun.

  • Variable-length arrays and the max() mess

    Variable-length arrays (VLAs) have a non-constant size that is determined (and which can vary) at run time; they are supported by the ISO C99 standard. Use of VLAs in the kernel has long been discouraged but not prohibited, so there are naturally numerous VLA instances to be found. A recent push to remove VLAs from the kernel entirely has gained momentum, but it ran into an interesting snag on the way.

  • Discussing PEP 572

    As is often the case, the python-ideas mailing list hosted a discussion about a Python Enhancement Proposal (PEP) recently. In some sense, this particular PEP was created to try to gather together the pros and cons of a feature idea that regularly crops up: statement-local bindings for variable names. But the discussion of the PEP went in enough different directions that it led to calls for an entirely different type of medium in which to have those kinds of discussions.

Linux Steam Controller Driver and LWN Kernel Coverage

TuxMachines - Thu, 2018-03-22 15:47
  • Steam Controller Linux Kernel Driver Updated To Work Happily With The Steam Client

    Last month we reported on a kernel driver being worked on for Valve's Steam Controller but it wasn't coming from Valve developers but rather an independent member of the community. That hid-steam driver continues to be hacked on.

    To date Valve has just been supporting the Steam Controller on Linux via the Steam client with handling the controller's behavior in user-space. There have also been some independent user-space programs to come about too for manipulating the Steam Controller, but this has been the first time a proper Linux kernel driver has been worked on for this popular gaming controller.

  • Time-based packet transmission

    Normally, when an application sends data over the network, it wants that data to be transmitted as quickly as possible; the kernel's network stack tries to oblige. But there are applications that need their packets to be transmitted within specific time windows. This behavior can be approximated in user space now, but a better solution is in the works in the form of the time-based packet transmission patch set.

    There are a number of situations where outgoing data should not necessarily be transmitted immediately. One example would be any sort of isochronous data stream — an audio or video stream, maybe — where each packet of data is relevant at a specific point in time. For such streams, transmitting ahead of time and buffering at the receiving side generally works well enough. But realtime control applications can be less flexible. Commands for factory-floor or automotive systems, for example, should be transmitted within a narrow period of time. Realtime applications can wait until the window opens before queuing data for transmission, of course, but any sort of latency that creeps in (due to high network activity, for example) may then cause the data to be transmitted too late.

  • Designing ELF modules

    The bpfilter proposal posted in February included a new type of kernel module that would run as a user-space program; its purpose is to parse and translate iptables rules under the kernel's control but in a contained, non-kernel setting. These "ELF modules" were reposted for review as a standalone patch set in early March. That review has happened; it is a good example of how community involvement can improve a special-purpose patch and turn it into a more generally useful feature.

    ELF modules look like ordinary kernel modules in a number of ways. They are built from source that is (probably) shipped with the kernel itself, they are compiled to a file ending in .ko, and they can be loaded into the kernel with modprobe. Rather than containing a real kernel module, though, that .ko file holds an ordinary ELF binary, as a user-space program would. When the module is "loaded", a special process resembling a kernel thread is created to run that program in user mode. The program will then provide some sort of service to the kernel that is best not run within the kernel itself.

  • Results of the MDN “Duplicate Pages” SEO experiment

    Following in the footsteps of MDN’s “Thin Pages” SEO experiment done in the autumn of 2017, we completed a study to test the effectiveness and process behind making changes to correct cases in which pages are perceived as “duplicates” by search engines. In SEO parlance, “duplicate” is a fuzzy thing. It doesn’t mean the pages are identical—this is actually pretty rare on MDN in particular—but that the pages are similar enough that they are not easily differentiated by the search engine’s crawling technology.

  • Raspberry Pi 3 Model B+ Benchmarks

    Last week on Pi Day marked the release of the Raspberry Pi 3 Model B+ with a slightly higher clocked Cortex-A53 processors, dual-band 802.11ac WiFi, faster Ethernet, and other minor enhancements over its predecessor. I've been spending the past few days putting the Raspberry Pi 3 Model B+ through its paces the past few days with an array of benchmarks while comparing the performance to other ARM SBCs as well as a few lower-end Intel x86 systems too. Here is all you need to know about the Raspberry Pi 3 B+ performance.

  • Porting L4Re and Fiasco.OC to the Ben NanoNote (Part 2)

    Having undertaken some initial investigations into running L4Re and Fiasco.OC on the MIPS Creator CI20, I envisaged attempting to get this software running on the Ben NanoNote, too. For a while, I put this off, feeling confident that when I finally got round to it, it would probably be a matter of just choosing the right compiler options and then merely fixing all the mistakes I had made in my own driver code. Little did I know that even the most trivial activities would prove more complicated than anticipated.

    As you may recall, I had noted that a potentially viable approach to porting the software would merely involve setting the appropriate compiler switches for “soft-float” code, thus avoiding the generation of floating point instructions that the JZ4720 – the SoC on the Ben NanoNote – would not be able to execute. A quick check of the GCC documentation indicated the availability of the -msoft-float switch. And since I have a working cross-compiler for MIPS as provided by Debian, there didn’t seem to be much more to it than that. Until I discovered that the compiler doesn’t seem to support soft-float output at all.

    I had hoped to avoid building my own cross-compiler, and apart from enthusiastic (and occasionally successful) attempts to build the Debian ones before they became more generally available, the last time I really had anything to do with this was when I first developed software for the Ben. As part of the general support for the device an OpenWrt distribution had been made available. Part of that was the recipe for building the cross-compiler and other tools, needed for building a kernel and all the software one would deploy on a device. I am sure that this would still be a good place to look for a solution, but I had heard things about Buildroot and so set off to investigate that instead.

  • Artila Releases New Linux-ready Cortex-A7 System on Module M-X6ULL

    Artila's new SODIMM module based on NXP i.MX6ULL ARM Cortex A7 CPU core operating up to 800MHz speed with Linux OS.
