Our Last Time Benchmarking Ubuntu 32-bit vs. 64-bit

Filed under
Graphics/Benchmarks

Over the years we have looked at the 32-bit vs. 64-bit x86 Linux performance for curiosity sake, showing how x86_64 can be much faster than i686, and just providing these values for a reference look and if for some reason are still running 32-bit Linux software including the OS while the hardware is 64-bit capable. For this final benchmarking look are fresh numbers when doing a clean install of Ubuntu 17.10 32-bit compared to Ubuntu 17.10 64-bit.

  • Linux To Get "Extended LTS" Releases, Kernel Support For Six Years

    Linux right now offers a "Long Term Support" release where support for the kernel branch is maintained for two years, which is nice compared to kernel releases usually dropping maintenance around N+1.1 after the release. But moving forward, Linux LTS releases will now be maintained for six years.

    The two-year Linux LTS cycle is suitable for many users, but one case where it's not long enough is the lifecycle of a smartphone and the status quo is many Android phones out there are still running on Linux kernels no longer receiving bug/security fixes. Via Google's Project Treble and cooperation with the upstream Linux community, that two year process is now being extended to six years.

  • Mesa 17.2.2 Set For Release Next Week

    For those not comfortable riding Mesa Git, Mesa 17.2.2 is set to be released early next week as the newest stable update for the open-source 3D graphics driver stack.

    Point release manager Juan Suarez Romero of Igalia is planning on releasing Mesa 17.2.2 next Monday, 2 October, if all goes well. So far there are 43 patches queued and a handful of more patches still possibly landing. Friday marked the release candidate for this newest point release.

  • SELinux (Security-Enhanced Linux)

    SELinux, or Security-Enhanced Linux, is a part of the Linux security kernel that acts as a protective agent on servers. In the Linux kernel, SELinux relies on mandatory access controls (MAC) that restrict users to rules and policies set by the system administrator. MAC is a higher level of access control than the standard discretionary access control (DAC), and prevents security breaches in the system by only processing necessary files that the administrator pre-approves.

  • Alpine Linux

    Alpine Linux is a small, security-oriented, lightweight Linux distribution based on the musl libc library and BusyBox utilities platform instead of GNU. It operates on bare-metal hardware, in a VM or even on a Raspberry Pi. The distribution is noncommercial and evolved for embedded and server-based workloads, although desktop OS use is possible.

  • Attend a Fedora Women Day 2017 event

    Fedora Women Day (FWD) is a worldwide series of events initiated by the Fedora Diversity Team. The events are dedicated to female contributors of the Fedora Project. During this day of celebration, local communities gather to present the accomplishments of women in the Fedora Project and thank them. FWD is also a great chance to promote the participation of more women and raise awareness about the gender gap in tech communities. Furthermore, FWD and events like it show the importance of diversity in open source projects such as Fedora.

  • Keep the Trump administration out of your private life with Tails 3.2 Linux distribution

    As we learned from the great patriot Edward Snowden, the US government can and will spy on you. Not caring about that invasion of privacy, and dismissing it with the flawed statement of "I have nothing to hide," is flat out idiotic. Regardless of what you do on your computer, or on the internet, your privacy is sacred, and quite frankly, it was earned by our forefathers that fought for our freedoms.

    If you do care about your privacy, and you want to keep the heavy-handed Trump administration or other government agency out of your private business, please know you aren't powerless. There is a specific Linux-based operating system that aims to protect your privacy from corrupt governments and other evildoers, such as hackers and spies. Called "Tails," it always runs in a live environment from a DVD or flash drive. In other words, especially with an optical disk, it will help to hide your footprints. Today, version 3.2 sees release.

  • Blockchain skills: Don't Try to Block the Chain

    Blockchain technology is on the rise. Some might presume Bitcoin is the reason behind it. While it was developed for the digital currency, developers are finding other uses of blockchain technology. Most prominently is the open source project Ethereum. The use of Ethereum has brought about smart contracts, which have proven to be quite functional within the financial industry. With its decentralized structure, blockchain technology could be a paradigm shift with vast boundaries.

  • Network Functions Virtualization: All Roads Lead to OPNFV

    Previously in our discussion of the Understanding OPNFV book, we provided an introduction to network functions virtualization (NFV) and explored the role of OPNFV in network transformation. We continue our series with a look at chapters 4 and 5, which provide a comprehensive description of the various open source NFV projects integrated by OPNFV and the carrier grade features contributed back to these upstream projects by the community. In this article, we cover these two topics briefly and provide some related excerpts from the Understanding OPNFV book.

  • Facebook re-licenses React.js, a new open source tool from Oath, and more news

    Recently, Facebook drew the ire of the open source community by licensing React.js (a widely-used JavaScript library) under a so-called BSD + Patents license. That license drew fears of patent litigation and React.js was rejected by the Apache Foundation and WordPress decided to ditch it. As a result of the backlash, the social media giant has backtracked and re-licensed the library.

  • An alarming number of patched Macs remain vulnerable to stealthy firmware hacks

    An alarming number of Macs remain vulnerable to known exploits that completely undermine their security and are almost impossible to detect or fix even after receiving all security updates available from Apple, a comprehensive study released Friday has concluded.

  • What Clarence Birdseye can teach us about container security

    Clarence Birdseye is generally considered to be the founder of the modern frozen food industry. In 1925, after a couple of false starts, he moved his General Seafood Corporation to Gloucester, Massachusetts. There, he used his newest invention, the double belt freezer, to freeze fish quickly using a pair of brine-cooled stainless steel belts. This and other Birdseye innovations centered on the idea that flash-freezing meant that only small ice crystals could form, and therefore cell membranes were not damaged. Over time, these techniques were applied to a wide range of food — including the ubiquitous frozen peas.

Industrial dev board builds on Raspberry Pi CM3

Kontron announced an industrial-focused “Passepartout” development kit built around a Raspberry Pi Compute Module 3 Light and equipped with a dual Ethernet, HDMI, CAN, 1-Wire, RPi 40-pin connectors. Kontron announced its first Raspberry Pi based product. The Passepartout — which is French for “goes everywhere” and the name of Phileas Fogg’s valet in Jules Verne’s “Around the World in Eighty Days” — builds upon the Linux-driven Raspberry Pi Compute Module 3 Light (CM3L). The Light version lacks the 4GB of eMMC flash of the standard CM3 module but still supports eMMC or microSD storage. The CM3L is otherwise identical, with features including a quad-core, 1.2GHz Broadcom BCM2837 and 1GB of LPDDR2 RAM. Read more

Patches For The Better Spectre STIBP Approach Revised - Version 7 Under Review

Version 7 of the task property based options to enable Spectre V2 userspace-userspace protection patches, a.k.a. the work offering improved / less regressing approach for STIBP, is now available for testing and code review. Tim Chen of Intel sent out the seventh revision to these patches on Tuesday night. Besides the Spectre V2 app-to-app protection modes, these patches include the work for disabling STIBP (Single Thread Indirect Branch Predictors) when enhanced IBRS (Indirect Branch Restricted Speculation) is supported/used, and allowing for STIBP to be enabled manually and just by default for non-dumpable tasks.
