GNOME 3.30 Desktop Environment Gets Beta 2 Release Ahead of September 5 Launch

Filed under
GNOME

Coming two weeks after the first beta release, the highly anticipated GNOME 3.30 desktop environment received a second beta release today as Michael Catanzaro informed us via an email announcement. This beta 2 release is tagged as GNOME 3.29.91, and it marks the Software String Freeze stage in the development cycle.

But it doesn't look like it was an easy release for the GNOME Release Team, as Michael Catanzaro reports build failures for several components, including GNOME Boxes, which didn't make it for this second beta release. As a consequence, numerous components weren't updated in this beta 2 release.

A Quick Look At The Windows Server vs. Linux Performance On The Threadripper 2990WX

Filed under
Graphics/Benchmarks

One of the frequent requests/comments stemming from the launch-day Windows 10 vs. Linux benchmarks on the new AMD Threadripper 2990WX were questions about whether this 32-core / 64-thread processor would do better with Windows Server given Microsoft's obvious tuning of that Windows flavor to high core/thread counts... Well, here are some initial figures with Windows Server 2016 and a Windows Server 2019 preview.

Given the immense interest and speculation about the Windows Server performance on the AMD Threadripper 2990WX, to see if it would give Linux better competition relative to Windows 10, I ran some initial benchmarks so far. I am still doing some more Windows vs. Linux exploration and benchmarking (a lot of other interesting tests from this new hardware) while for today are the Windows Server 2016/2019 results alongside the other operating system tests on this 2990WX system.

Both Canonical and Red Hat emailed us with regards to the L1 Terminal Fault security vulnerability, which are documented as CVE-2018-3620 for operating systems and System Management Mode (SMM), CVE-2018-3646 for impacts to virtualization, as well as CVE-2018-3615 for Intel Software Guard Extensions (Intel SGX). They affect all Linux-based operating system and machines with Intel CPUs.

"It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault (L1TF). A local attacker in a guest virtual machine could use this to expose sensitive information (memory from other guests or the host OS)," reads the Ubuntu security advisory.

HowTos

I have been out of touch for the past six months, because I accepted a teaching position in Amsterdam. The amount of time that required, and the weekly commute from Switzerland (yes, really, weekly), was vastly more than I expected, and left me no time to do justice to my blog. But now I am back again, and determined to manage my time more effectively and keep up with blogging.

Although I haven't been writing, I certainly have been keeping up with news and developments in the Linux world. What really inspired me to get busy and write again was the announcement of LMDE 3 (Cindy) Beta. Hooray! How long have we been waiting for this? It feels like years. Oh, that's because it has been years.

  • How to install Linux apps on your Chromebook

    Chromebooks are great because they're simple: there's a lot you can get done with web services without exposing yourself to the troubles and security issues that plague more complex platforms.

    But if you need to do a bit more with your Chromebook, you have a few options. Most Chromebooks these days allow you to install apps from the Google Play Store, which should fill most productivity gaps. If not, you'll soon have one more option: installing Linux apps. To be clear, you've been able to install Linux apps on Chromebooks for years because Chrome OS is Linux. But, it's about to get much easier.

  • Top 5 Features Still Missing From Chrome OS

    Google’s Chrome OS gets a lot of things right, and the platform has evolved considerably over the years. Not only does it offer an always up-to-date version of the Chrome browser, but there are also Android apps, stylus input, and even Linux support on some devices. However, Chrome OS is far from perfect. You have to make compromises if you choose to live with a Chromebook, but you shouldn’t have to make quite this many. Here are the top five things Google should fix.

  • Walmart's selling an all-aluminum Chromebook with a comfy keyboard for just $220

    If you’re not considering a Chromebook when you're shopping for a notebook, you’re doing it wrong.

OSCON 2018 Events Coverage by LWN

Filed under
OSS
  • Using AI on patents

    Software patents account for more than half of all utility patents granted in the US over the past few years. Clearly, many companies see these patents as a way to fortune and growth, even while software patents are hated by many people working in the free and open-source movements. The field of patenting has now joined the onward march of artificial intelligence. This was the topic of a talk at OSCON 2018 by Van Lindberg, an intellectual-property lawyer, board member and general counsel for the Python Software Foundation, and author of the book Intellectual Property and Open Source. The disruption presented by deep learning ranges from modest enhancements that have already been exploited—making searches for prior art easier—to harbingers of automatic patent generation in the future.

  • Diverse technical topics from OSCON 2018

    The O'Reilly Open Source Conference (OSCON) returned to Portland, Oregon in July for its 20th meeting. Previously, we covered some retrospectives and community-management talks that were a big part of the conference. Of course, OSCON is also a technology conference, and there were lots of talks on various open-source software platforms and tools.

    An attendee who was coming back to OSCON after a decade would have been somewhat surprised by the themes of the general technical sessions, though. Early OSCONs had a program full of Perl, Python, and PHP developer talks, including the famous "State of The Onion" (Perl) keynote. Instead, this year's conference mostly limited the language-specific programming content to the tutorials. Most of the technical sessions in the main program were about platforms, administration, or other topics of general interest, some of which we will explore below.

TransmogrifAI From Salesforce

  • Salesforce plans to open-source the technology behind its Einstein machine-learning services
    Salesforce is open-sourcing the method it has developed for using machine-learning techniques at scale — without mixing valuable customer data — in hopes other companies struggling with data science problems can benefit from its work. The company plans to announce Thursday that TransmogrifAI, which is a key part of the Einstein machine-learning services that it believes are the future of its flagship Sales Cloud and related services, will be available for anyone to use in their software-as-a-service applications. Consisting of less than 10 lines of code written on top of the widely used Apache Spark open-source project, it is the result of years of work on training machine-learning models to predict customer behavior without dumping all of that data into a common training ground, said Shubha Nabar, senior director of data science for Salesforce Einstein.
  • Salesforce open-sources TransmogrifAI, the machine learning library that powers Einstein
    Machine learning models — artificial intelligence (AI) that identifies relationships among hundreds, thousands, or even millions of data points — are rarely easy to architect. Data scientists spend weeks and months not only preprocessing the data on which the models are to be trained, but extracting useful features (i.e., the data types) from that data, narrowing down algorithms, and ultimately building (or attempting to build) a system that performs well not just within the confines of a lab, but in the real world.
