LibreELEC Embedded Linux OS Now Compatible with Windows 10 Fall Creators Update

Filed under
Linux

The LibreELEC 8.2.1 update is based on the latest Kodi 17.6 "Krypton" open-source and cross-platform media center software and it mostly patches some Samba (SMB) "file exists" share errors on Windows 10 Fall Creators Update by updating the protocol to Samba 4.6.10, implementing SMB client options for minimum SMB protocol and an SMB legacy security option with NTLMv1, and disabling SPNEGO.

"LibreELEC 8.2.x includes changes that allow the Kodi SMB client and our embedded Samba server to support SMB2/3 connections; deprecating SMB1 to improve security and performance. This is necessary to cope with changes Microsoft introduced in the Windows 10 ‘Fall Creators Update’ to resolve SMB1 security issues," explained the developers.

Ubuntu Boot Times From Linux 4.6 To 4.15 Kernels

Filed under
Graphics/Benchmarks
Linux
Ubuntu

It's been a while since last doing any Linux boot speed comparisons while this morning I have some numbers to share when looking at the boot performance from the Linux 4.6 kernel through Linux 4.15 Git to see how it's changed over time,

These tests were being done using a Lenovo ThinkPad X1 Carbon notebook using a mature Intel Broadwell CPU. Linux 4.6 through 4.15 Git was chosen since that's as far back as the mainline kernel would work with this Ubuntu 17.10 user-space. Linux 4.5 and older would fail to boot.

7 tools for analyzing performance in Linux with bcc/BPF

Filed under
Linux

A new technology has arrived in Linux that can provide sysadmins and developers with a large number of new tools and dashboards for performance analysis and troubleshooting. It's called the enhanced Berkeley Packet Filter (eBPF, or just BPF), although these enhancements weren't developed in Berkeley, they operate on much more than just packets, and they do much more than just filtering. I'll discuss one way to use BPF on the Fedora and Red Hat family of Linux distributions, demonstrating on Fedora 26.

BPF can run user-defined sandboxed programs in the kernel to add new custom capabilities instantly. It's like adding superpowers to Linux, on demand. Examples of what you can use it for include:

Why the open source community needs a diverse supply chain

Filed under
OSS

Diversity and inclusivity in the technology industry—and in open source communities more specifically—have received a lot of coverage, both on Opensource.com and elsewhere. One approach to the issue foregrounds arguments about concepts that are more abstract—like human decency, for example.

But the "supply chain" metaphor works, too. And it can be an effective argument for championing greater inclusivity in our open organizations, especially when people dismiss arguments based on appeals to abstract concepts. Open organizations require inclusivity, which is a necessary input to get the diversity that reduces the risk in our supply chain.

Programming: Swift, Brilliant Jerks in Engineering, and Career Path for Software Developers

Filed under
Development
  • Swift code will run on Google's Fuchsia OS

    A few days ago, there was a flash-in-the-pan controversy over Google "forking" Apple's open-source programming language Swift. After a few minutes of speculation over whether Google was going to make its own special flavor of the language for its own purposes, Swift's creator Chris Lattner (who now works at Google) helpfully clarified the situation:

  • Brilliant Jerks in Engineering

    This are numerous articles and opinions on the topic, including Brilliant Jerks Cost More Than They Are Worth, and It's Better to Avoid a Toxic Employee than Hire a Superstar. My colleague Justin Becker is also giving a talk at QConSF 2017 on the topic: Am I a Brilliant Jerk?.

    It may help to clarify that "brilliant jerk" can mean different things to different people. To illustrate, I'll describe two types of brilliant jerks: the selfless and the selfish, and their behavior in detail. I'll then describe the damage caused by these jerks, and ways to deal with them.

    The following are fictional characters. These are not two actual engineers, but are collections of related traits to help examine this behavior beyond the simple "no asshole rule." These are engineers who by default act like jerks, not engineers who sometimes act that way.

  • [Older] The missing career path for software developers

    You started hacking on technology thrilled with every stroke of the key, making discoveries with every commit. You went about solving problems, finding new challenges. You were happy for a while, until you hit a plateau. There was a choice to be made. Continue solving the same problems or start managing others. You tried it out, and hated it. Longing to focus on technology, not people, you turned to your open source project. When it became successful, you became an open source maintainer but ended up overwhelmed and burned out. Hoping to get back to doing work that fascinates you, you went work for yourself. Lacking experience running a business, you're crushed with all the decisions you need to make. You’re nearing burnout — again. It feels like you’re on a hamster wheel.

Mastodon is Free Software, But It Does Not Respect Free Speech

  • Extra KVM Changes For Linux 4.15 Bring UMIP Support, AMD SEV Changes Delayed

    As some additional work past the KVM changes for Linux 4.15 submitted last week, a few more feature items have been queued.

    The second batch of Kernel-based Virtual Machine (KVM) updates sent in today for Linux 4.15 include ARM GICv4 support, x86 bug fixes, the AMD VFIO NFT performance fix, and x86 guest UMIP support. Landing already with Linux 4.15 is Intel UMIP capabilities for User-Mode Instruction Prevention to prevent certain instructions from being executed if the ring level is greater than zero. This latest KVM pull update adds this UMIP support to its space for both real and emulated guests.

  • AMD EPYC Is Running Well On Linux 4.15

    Of the many changes coming for Linux 4.15, as detailed this weekend Radeon GPU and AMD CPU customers have a lot to be thankful for with this new kernel update currently in development. Here are some initial benchmarks of the Linux 4.15 development kernel using an AMD EPYC 7601 32-core / 64-thread setup.

    When it comes to EPYC in Linux 4.15, the kernel side-bits have landed for Secure Encrypted Virtualization (SEV), CPU temperature monitoring support now working, and improved NUMA node balancing.

Security: Uber Sued, Intel ‘Damage Control’, ZDNet FUD, and XFRM Privilege Escalation

  • Uber hit with 2 lawsuits over gigantic 2016 data breach
    In the 48 hours since the explosive revelations that Uber sustained a massive data breach in 2016, two separate proposed class-action lawsuits have been filed in different federal courts across California. The cases allege substantial negligence on Uber’s part: plaintiffs say the company failed to keep safe the data of the affected 50 million customers and 7 million drivers. Uber reportedly paid $100,000 to delete the stolen data and keep news of the breach quiet. On Tuesday, CEO Dara Khosrowshahi wrote: “None of this should have happened, and I will not make excuses for it.”
