Mozilla: Hiring a Vice President From Facebook, Homepage for the JavaScript Specification and More

Filed under
Moz/FF
  • Welcome Lindsey Shepard, VP Product Marketing [Ed: Hiring from Facebook (under criminal investigation for privacy infringement crimes) for VP role. Worst Mozilla hire since it put a Microsoft person -- yes, the company that puts back doors in everything and is most cooperative with the NSA (started PRISM) -- in charge of "security".]

    Most recently, Lindsey headed up corporate-level marketing for Facebook Inc., including leading product marketing for Facebook’s core products: News Feed, News, Stories, Civic Engagement, Privacy and Safety. Before joining Facebook, Lindsey led marketing at GoldieBlox, a Bay Area start-up focused on bridging the gender gap in STEM.

  • A Homepage for the JavaScript Specification

    Ecma TC39, the JavaScript Standards Committee, is proud to announce that we have shipped a website for following updates to the JavaScript specification. This is the first part of a two-part project aimed at improving our information distribution and documentation. The website provides links to our most significant documents, as well as a list of proposals that are near completion. Our goal is to help people find the information they need in order to understand the specification and our process.

    While the website is currently an MVP and very simple, we have plans to expand it. These plans include a set of documentation about how we work. We will experiment with other features as the need arises.

    The website comes as part of work that began last year to better understand how the community was accessing information about the work around the JavaScript specification. We did a series of in-person interviews, followed by a widely distributed survey to better understand what people struggled with. One of the biggest requests was that we publish and maintain a website that helps people find the information they are looking for.

  • A look at Mozilla's data science tooling, Google's Season of Docs, and more news

    Mozilla released Iodide, a new tool for publishing data science. Still in very early alpha, Iodide is a tool designed to help scientists write interactive documents. It is similar, but not exactly equivalent to Jupyter Notebooks or R Markdown in RStudio. Brendan Colloran shares all the technical details in a post on the Mozilla Hacks blog.If you want explore Iodide yourself, Mozilla has a demo site available.

Development
  • WadC 3.0

    A couple of weeks ago I release version 3.0 of Wad Compiler, a lazy functional programming language and IDE for the construction of Doom maps.

    3.0 introduces more flexible randomness with rand; two new test maps (blockmap and bsp) that demonstrate approaches to random dungeon generation; some useful data structures in the library; better Hexen support and a bunch of other improvements.

  • Rcpp 1.0.1: Updates

    Following up on the 10th anniversary and the 1.0.0. release, we excited to share the news of the first update release 1.0.1 of Rcpp. package turned ten on Monday—and we used to opportunity to mark the current version as 1.0.0! It arrived at CRAN overnight, Windows binaries have already been built and I will follow up shortly with the Debian binary.

    We had four years of regular bi-monthly release leading up to 1.0.0, and having now taken four months since the big 1.0.0 one. Maybe three (or even just two) releases a year will establish itself a natural cadence. Time will tell.

  • Django 2.2 release candidate 1 released

    Django 2.2 release candidate 1 is the final opportunity for you to try out the salmagundi of new features before Django 2.2 is released.

    The release candidate stage marks the string freeze and the call for translators to submit translations. Provided no major bugs are discovered that can't be solved in the next two weeks, Django 2.2 will be released on or around April 1. Any delays will be communicated on the django-developers mailing list thread.

  • Qt 3D Pairs Nicely With Vulkan & NVIDIA RTX To Make A Beautiful Path Tracer

    Not to be confused with Apple's Quartz graphics layer, a new open-source project called Quartz by developer Michał Siejak is producing stunningly beautiful results while being powered by the Vulkan graphics API, making use of Qt 3D, and NVIDIA RTX support within this path tracer.

    Michał Siejak open-sourced his "Quartz" project this past week and it's the latest open-source Vulkan project catching our eyes. Quartz is a path tracer designed around NVIDIA RTX (and, yes, does require a NVIDIA GPU) and delivering stunning results as an open-source path tracer that works on Windows and Linux. Beyond that, it offers a JavaScript/ES7-like description language for interacting with this path tracing renderer. The ES7-based description language is based on Qt5's QML.

Canonical Says Ubuntu 14.04 Extended Security Maintenance Begins April 25, 2019

Filed under
Ubuntu

Released five years ago on April 17th, 2014, the Ubuntu 14.04 LTS (Trusty Tahr) operating system series will reach its end of life next month on April 30th. Following on the success of the Ubuntu 12.04 LTS (Precise Pangolin) operating system series, Canonical announced some time ago that it would offer its Extended Security Maintenance (ESM) commercial package to Ubuntu 14.04 LTS users as well.

Canonical said it would reveal more details about when the ESM (Extended Security Maintenance) offering is available for Ubuntu 14.04 LTS (Trusty Tahr), so the company now announced that users who want to continue using the operating system and still receive security updates after the April 30th end of life, can purchase the ESM package beginning April 25th, 2019.

A major new version of the Geary e-mail client is now available for Linux users to download.

Now, you’ll forgiven for feeling a sense of deja vu upon reading that as it’s only been a couple of weeks since the release of Geary 0.13 (itself the first update to the email app this year).

But there’s a reason why a new release has appeared so soon after the last…

Forbes Says The Raspberry Pi Is Big Business

Filed under
GNU
Linux
Hardware

Not that it’s something the average Hackaday reader is unaware of, but the Raspberry Pi is a rather popular device. While we don’t have hard numbers to back it up (extra credit for anyone who wishes to crunch the numbers), it certainly seems a day doesn’t go by that there isn’t a Raspberry Pi story on the front page. But given that a small, cheap, relatively powerful, Linux computer was something the hacking community had dreamed of for years, it’s hardly surprising.

[...]

So where has the Pi been seen punching a clock? At Sony, for a start. The consumer electronics giant has been installing Pis in several of their factories to monitor various pieces of equipment. They record everything from temperature to vibration and send that to a centralized server using an in-house developed protocol. Some of the Pis are even equipped with cameras which feed into computer vision systems to keep an eye out for anything unusual.

[Parmy] also describes how the Raspberry Pi is being used in Africa to monitor the level of trash inside of garbage bins and automatically dispatch a truck to come pick it up for collection. In Europe, they’re being used to monitor the health of fueling stations for hydrogen powered vehicles. All over the world, businesses are realizing they can build their own monitoring systems for as little as 1/10th the cost of turn-key systems; with managers occasionally paying for the diminutive Linux computers out of their own pocket.

Graphics/Benchmarks
  • NVIDIA 418.49.04 Linux Driver Brings Host Query Reset & YCbCr Image Arrays

    NVIDIA has issued new Vulkan beta drivers leading up to the Game Developers Conference 2019 as well as this next week there being NVIDIA's GPU Technology Conference (GTC) nearby in California.

    The only publicly mentioned changes to this weekend's NVIDIA 418.49.04 Linux driver update (and 419.62 on the Windows side) is support for the VK_EXT_host_query_reset and VK_EXT_ycbcr_image_arrays extensions.

  • Nouveau NIR Support Lands In Mesa 19.1 Git

    It shouldn't come as any surprise, but landing today in Mesa 19.1 Git is the initial support for the Nouveau Gallium3D code to make use of the NIR intermediate representation as an alternative to Gallium's TGSI.

    The Nouveau NIR support is part of the lengthy effort by Red Hat developers on supporting this IR as part of their SPIR-V and compute upbringing. The NIR support is also a stepping stone towards a potential NVIDIA Vulkan driver in the future.

  • Vulkan 1.1.104 Brings Native HDR, Exclusive Fullscreen Extensions

    With the annual Game Developers' Conference (GDC) kicking off tomorrow in San Francisco, Khronos' Vulkan working group today released Vulkan 1.1.104 that comes with several noteworthy extensions.

    Vulkan 1.1.104 is the big update for GDC 2019 rather than say Vulkan 1.2, but it's quite a nice update as part of the working group's weekly/bi-weekly release regiment. In particular, Vulkan 1.1.104 is exciting for an AMD native HDR extension and also a full-screen exclusive extension.

  • Interested In FreeSync With The RADV Vulkan Driver? Testing Help Is Needed

    Since the long-awaited introduction of FreeSync support with the Linux 5.0 kernel, one of the missing elements has been this variable rate refresh support within the RADV Vulkan driver.

    When the FreeSync/VRR bits were merged into Linux 5.0, the RadeonSI Gallium3D support was quick to land for OpenGL games but RADV Vulkan support was not to be found. Of course, RADV is the unofficial Radeon open-source Vulkan driver not officially backed by AMD but is the more popular driver compared to their official AMDVLK driver or the official but closed driver in their Radeon Software PRO driver package (well, it's built from the same sources as AMDVLK but currently with their closed-source shader compiler rather than LLVM). So RADV support for FreeSync has been one of the features users have been quite curious about and eager to see.

9 Admirable Graphical File Managers

Filed under
GNU
Linux
Software

Being able to navigate your local filesystem is an important function of personal computing. File managers have come a long way since early directory editors like DIRED. While they aren’t cutting-edge technology, they are essential software to manage any computer.

File management consists of creating, opening, renaming, moving / copying, deleting and searching for files. But file managers also frequently offer other functionality.

In the field of desktop environments, there are two desktops that dominate the open source landscape: KDE and GNOME. They are smart, stable, and generally stay out of the way. These use the widget toolkits Qt and GTK respectively. And there are many excellent Qt and GTK file managers available. We covered the finest in our Qt File Managers Roundup and GTK File Managers Roundup. But with Linux, you’re never short of alternatives.

There are many graphical non-Qt and non-Gtk file managers available. This article examines 9 such file managers. The quality is remarkably good.

Slimbook & Kubuntu - Combat Report 6

Filed under
KDE

Here we are gathered, for another episode of drama, thrill and technological escapades in the land of Tux. Starring one Slimbook Pro2 in the main role, with a trusty sidekick called Bionic Beaver of the Kubuntu clan. We've had quite a few episodes so far, and they tell a rather colorful story of progress, beauty and bugs.

Over the past few months, I've detailed my usage of the laptop and its operating system in serious, real-life situations, with actual productivity needs and challenges. This isn't just a test, this is running the machine properly. Many things work well, but then, there are problems, too. Of course, you can read all about those in the previous articles, and again, for the sake of simplicity, I'm only going to link to only the last report here. If you're truly intrigued, I'm sure you can find your way around.

[..].

I believe the Slimbook - with its Kubuntu brains - is slowly settling down. The one thing that is certain is that system updates bring in small tweaks and fixes all the time, and it's a shame that we can't have that from the very first minute. On the other hand, the system is stable, robust, and there are no regressions. I am quite pleased.

But there are still many things that can improved. Small things. The nth-order fun that isn't immediate or obvious, and so people don't see it until they come across a non-trivial use case, and then things start falling apart. This is true for all operating system, it's only the matter of how much. Plasma has made great strides in becoming semi-pro, and I hope it will get better still. Onwards.

Security: Cult of the Dead Cow, Huawei, and LastPass

  • Open Source Security Podcast: Episode 137.5 - Holy cow Beto was in the cDc, this is awesome!

    Josh and Kurt talk about Beto being in the Cult of the Dead Cow (cDc). This is a pretty big deal in a very good way. We hit on some history, why it's a great thing, what we can probably expect from opponents. There's even some advice at the end how we can all help. We need more politicians with backgrounds like this.

  • Is Huawei a security threat? Seven experts weigh in

    Regardless of how the suit shakes out, it will hardly be the last volley in the ongoing battle. Is the US right to target Chinese equipment makers like Huawei, or has the company, as it maintains, been unfairly maligned? The Verge convened experts, from prominent China-watchers to Sen. Marco Rubio, to give their views.

  • Should you be concerned about LastPass uploading your passwords to its server? [Ed: Wladimir Palant says what I have been saying for years. Alas, it fell on some deaf ears. LastPass is a dangerous trap. Very bad, and not even for convenience. Faith-based security.]

    I’ve written a number of blog posts on LastPass security issues already. The latest one so far looked into the way the LastPass data is encrypted before it is transmitted to the server. The thing is: when your password manager uploads all data to its server backend, you normally want to be very certain that the data visible to the server is useless both to attackers who manage to compromise the server and company employees running that server. Early last year I reported a number of issues that allowed subverting LastPass encryption with comparably little effort. The most severe issues have been addressed, so all should be good now?

    Sadly, no. It is absolutely possible for a password manager to use a server for some functionality while not trusting it. However, LastPass has been designed in a way that makes taking this route very difficult. In particular, the decision to fall back to server-provided pages for parts of the LastPass browser extension functionality is highly problematic. For example, whenever you access Account Settings you leave the trusted browser extension and access a web interface presented to you by the LastPass server, something that the extension tries to hide from you. Some other extension functionality is implemented similarly.

  • RQuantLib 0.4.8: Small updates

    A new version 0.4.8 of RQuantLib reached CRAN and Debian. This release was triggered by a CRAN request for an update to the configure.ac script which was easy enough (and which, as it happens, did not result in changes in the configure script produced). I also belatedly updated the internals of RQuantLib to follow suit to an upstream change in QuantLib. We now seamlessly switch between shared_ptr<> from Boost and from C++11 – Luigi wrote about the how and why in an excellent blog post that is part of a larger (and also excellent) series of posts on QuantLib internals.

    QuantLib is a very comprehensice free/open-source library for quantitative finance, and RQuantLib connects it to the R environment and language.

  • 10 Python image manipulation tools

    Today's world is full of data, and images form a significant part of this data. However, before they can be used, these digital images must be processed—analyzed and manipulated in order to improve their quality or extract some information that can be put to use.

    Common image processing tasks include displays; basic manipulations like cropping, flipping, rotating, etc.; image segmentation, classification, and feature extractions; image restoration; and image recognition. Python is an excellent choice for these types of image processing tasks due to its growing popularity as a scientific programming language and the free availability of many state-of-the-art image processing tools in its ecosystem.

    This article looks at 10 of the most commonly used Python libraries for image manipulation tasks. These libraries provide an easy and intuitive way to transform images and make sense of the underlying data.

    This article is about text processing in Rust, but it also contains a quick introduction to pattern matching, which can be very handy when working with text.

    Strings are a huge subject in Rust, which can be easily realized by the fact that Rust has two data types for representing strings as well as support for macros for formatting strings. However, all of this also proves how powerful Rust is in string and text processing.

    Apart from covering some theoretical topics, this article shows how to develop some handy yet easy-to-implement command-line utilities that let you work with plain-text files. If you have the time, it'd be great to experiment with the Rust code presented here, and maybe develop your own utilities.

Canonical Releases Important Linux Kernel Patch for Ubuntu 16.04 LTS, Update Now

Filed under
Linux
Ubuntu

The new Linux kernel security update is here to address five security issues discovered by various security researchers in the Linux 4.4 kernel used in the Ubuntu 16.04 LTS (Xenial Xerus) operating system series and official derivatives that aren't using the Linux 4.15 HWE (Hardware Enablement) kernel from Ubuntu 18.04 LTS (Bionic Beaver).

These include a flaw (CVE-2017-18241) in Linux kernel's F2FS file system implementation, which incorrectly handled the noflush_merge mount option, and multiple integer overflows (CVE-2018-7740) in the hugetlbfs implementation. Both issues could allow local attackers to crash the vulnerable system through a denial of service.

Fedora 29 Linux Gaming Report: The Nvidia, Radeon And Steam User Experience

Filed under
Linux
Gaming

Gaming on Linux. Depending on who you talk to, getting stuff like Steam up and running and graphics drivers installed can be a tedious exercise, or ridiculously straightforward. That's because people don't really game on Linux. They game on Fedora, Manjaro, Ubuntu, Deepin, Solus. They game on Debian-based distributions or Arch-based distributions. Each with their own philosophies on free (as in open source and freely distributed) versus non-free (Steam and proprietary Nvidia drivers) software. Each with their own approaches to stability, affecting which versions of drivers are available out of the box.

While there are certain procedures and best practices that persist across any distro, the variances can be daunting for new users. And that's the jumping-off point for this series.

These are some of the major reasons why you should use Fedora. It might not be popular as Ubuntu or comes with advanced tools by default as Kali Linux or user-friendly as Linux Mint, but it has a solid base when it comes to latest features and security. Another fact is, anyone, can build a Linux distribution but you should not use one run by a single or few people. Fedora is backed by RedHat, one of the most reputable names in Linux industry and hence you will have peace of mind.

OpenXR 0.90 Released For AR/VR Standard - Monado Is An Open-Source Implementation

Filed under
OSS

Last year we were expecting The Khronos Group to introduce OpenXR 1.0 for this standard to address fragmentation and provide interoperability in the VR space followed by AR. That debut last year didn't happen although they did show off the first demonstration at SIGGRAPH. This week though at GDC they are announcing the OpenXR 0.90 provisional specification release.

The OpenXR 0.90 provisional specification is now available today. Yes, v0.90 and not 1.0... This caught me by surprise too when being briefed last week. This provisional specification ended up incorporating not only VR support but also AR (augmented reality) into the design. They are hoping for more feedback from AR/VR developers before officially declaring 1.0 especially with the AR support squeezing in when originally they only anticipated to get that in post-1.0.

Lessons in Vendor Lock-in: 3D Printers

One interesting thing about the hobbyist 3D printing market is that it was founded on free software and open hardware ideals starting with the RepRap project. The idea behind that project was to design a 3D printer from off-the-shelf parts that could print as many of its own parts as possible (especially more complex, custom parts like gears). Because of this, the first generation of 3D printers were all homemade using Arduinos, stepper motors, 3D-printed gears and hardware you could find in the local hardware store. As the movement grew, a few individuals started small businesses selling 3D printer kits that collected all the hardware plus the 3D printed parts and electronics for you to assemble at home. Later, these kits turned into fully assembled and supported printers, and after the successful Printrbot kickstarter campaign, the race was on to create cheaper and more user-friendly printers with each iteration. Sites like Thingiverse and YouMagine allowed people to create and share their designs, so even if you didn't have any design skills yourself, you could download and print everyone else's. These sites even provided the hardware diagrams for some of the more popular 3D printers. The Free Software ethos was everywhere you looked. Read more
