The updated Settings features in GNOME 3.26, released on September 13.When writing open source software, we often obsess about making our logic elegant and concise, coming up with clever ways to execute tasks and demonstrate ideas. But we sometimes forget a key fact: Software is not useful if it is not easy to use.read more

An introduction to machine learning today

Thursday 21st of September 2017 01:06:22 PM
Machine learning and artificial intelligence (ML/AI) mean different things to different people, but the newest approaches have one thing in common: They are based on the idea that a program's output should be created mostly automatically from a high-dimensional and possibly huge dataset, with minimal or no intervention or guidance from a human. Open source tools are used in a variety of machine learning and artificial intelligence projects. In this article, I'll provide an overview of the state of machine learning today.read more

LWN (Now Open Access): Kernel Configuration, Linux 4.14 Merge Window, Running Android on a Mainline Graphics Stack

  • A different approach to kernel configuration
    The kernel's configuration system can be challenging to deal with; Linus Torvalds recently called it "one of the worst parts of the whole project". Thus, anything that might help users with the process of configuring a kernel build would be welcome. A talk by Junghwan Kang at the 2017 Open-Source Summit demonstrated an interesting approach, even if it's not quite ready for prime time yet. Kang is working on a Debian-based, cloud-oriented distribution; he wanted to tweak the kernel configuration to minimize the size of the kernel and, especially, to reduce its attack surface by removing features that were not needed. The problem is that the kernel is huge, and there are a lot of features that are controlled by configuration options. There are over 300 feature groups and over 20,000 configuration options in current kernels. Many of these options have complicated dependencies between them, adding to the challenge of configuring them properly.
  • The first half of the 4.14 merge window
    September 8, 2017 As of this writing, just over 8,000 non-merge changesets have been pulled into the mainline kernel repository for the 4.14 development cycle. In other words, it looks like the pace is not slowing down for this cycle either. The merge window is not yet done, but quite a few significant changes have been merged so far. Read on for a summary of the most interesting changes entering the mainline in the first half of this merge window.
  • Running Android on a mainline graphics stack
    The Android system may be based on the Linux kernel, but its developers have famously gone their own way for many other parts of the system. That includes the graphics subsystem, which avoids user-space components like X or Wayland and has special (often binary-only) kernel drivers as well. But that picture may be about to change. As Robert Foss described in his Open Source Summit North America presentation, running Android on the mainline graphics subsystem is becoming possible and brings a number of potential benefits. He started the talk by addressing the question of why one might want to use mainline graphics with Android. The core of the answer was simple enough: we use open-source software because it's better, and running mainline graphics takes us toward a fully open system. With mainline graphics, there are no proprietary blobs to deal with. That, in turn, makes it easy to run current versions of the kernel and higher-level graphics software like Mesa.

Red Hat: Ansible Tower, Patent Promise, and Shares Declining

  • Red Hat’s automation solution spreading among APAC enterprises
    Red Hat recently shared revealed its agentless automation platform is spreading among enterprises in APAC countries like Australia, China, India and Singapore. The company asserts its Ansible Tower helps enterprises cut through the complexities of modern IT environments with powerful automation capabilities that improve productivity and reduce downtime. “Today’s business demands can mean even greater complexity for many organisations. Such dynamic environments can necessitate a new approach to automation that can improve speed, scale and stability across IT environments,” says head of APAC office of technology at Red Hat, Frank Feldmann.
  • Red Hat broadens patent pledge to most open-source software
    Red Hat, the world's biggest open source company, has expanded its commitment on patents, which had originally been not to enforce its patents against free and open source software.
  • Red Hat expands Patent Promise
    Open-source software provider Red Hat has revised its Patent Promise, which was initially intended to discourage patent aggression against free and open-source software. The expanded version of the defensive patent aggregation scheme extends the zone of non-enforcement to all of Red Hat’s patents and all software under “well-recognised” open-source licenses. In its original Patent Promise in 2002, Red Hat said software patents are “inconsistent with open-source and free software”.
