How would you like to pick and choose what aspects of your operating system you want upgraded, and leave the ones you know, love, and are accustomed to how they are?

Why the operating system matters in a containerized world

Filed under
OS

Applications running in Linux containers are isolated within a single copy of the operating system running on a physical server. This approach stands in contrast to hypervisor-based virtualization in which each application is bound to a complete copy of a guest operating system and communicates with the hardware through the intervening hypervisor. As a result, containers consume very few system resources such as memory and impose essentially no performance overhead on the application.

DemocracyOS promotes civic engagement on both sides

Interviews

Using DemocracyOS represents a challenge for any institution used to make decisions in the traditional way. It is designed for governments to open themselves up to citizen engagement, but power is usually conservative. But the biggest challenge is probably to fight against the presumption that citizens are naturally apathetic and shun commitment. Our challenge is cultural, not technological.

Kernel Developers Begin Work On CPPC Processor Performance Controls

Filed under
OS

Ashwin Chaugule of Linaro has announced his experimental kernel implementation of Collaborative Processor Performance Controls (CPPC) that is part of the ACPI 5.1 specification.

An increasing amount of x86 and ARM64 hardware is expected in the marketplace soon that supports CPPC, which is a new interface for CPU performance control between the OS and platform, while right now it's just exposed by a limited number of systems. Here's more from Ashwin's description:
CPPC is the new interface for CPU performance control between the OS and the platform defined in ACPI 5.0+. The interface is built on an abstract representation of CPU performance rather than raw frequency.

elementary OS Freya Beta Is Out, Still the Most Beautiful OS in the World

Filed under
OS

“Freya inherits core components from Ubuntu 14.04.1 LTS such as the Linux kernel (version 3.13), hardware drivers, and graphics stack. This includes support for EFI stub-loading, which is a kernel feature that enables booting directly from (U)EFI, without the need for an additional bootloader such as GRUB. Ubiquity does not yet have support for this configuration, but one of our developers has created a guide for a GRUB-free install of Freya on modern Mac computers using rEFInd.”

Additionally, the MPlayer-based video playback application also gets the "--image-display-duration" option for controlling the duration of image display, and a new "dcomposition" flag for controlling DirectComposition.

  • Report: If DOD Doesn't Embrace Open Source, It'll 'Be Left Behind'
    Unless the Defense Department and its military components levy increased importance on software development, they risk losing military technical superiority, according to a new report from the Center for a New American Security. In the report, the Washington, D.C.-based bipartisan think tank argues the Pentagon, which for years has relied heavily on proprietary software systems, “must actively embrace open source software” and buck the status quo. Currently, DOD uses open source software “infrequently and on an ad hoc basis,” unlike tech companies like Google, Amazon and Facebook that wouldn’t exist without open source software.
  • The Honey Trap of Copy/Pasting Open Source Code
    I couldn’t agree more with Bill Sourour’s article ‘Copy.Paste.Code?’ which says that copying and pasting code snippets from sources like Google and StackOverflow is fine as long as you understand how they work. However, the same logic can’t be applied to open source code. When I started open source coding at the tender age of fourteen, I was none the wiser to the pitfalls of copy/pasting open source code. I took it for granted that if a particular snippet performed my desired function, I could just insert it into my code, revelling in the fact that I'd just gotten one step closer to getting my software up and running. Yet, since then, through much trial and error, I’ve learned a thing or two about how to use open source code effectively.
  • Affordable, Open Source, 3D Printable CNC Machine is Now on Kickstarter
    The appeals of Kickstarter campaigns are many. There are the rewards for backers, frequently taking the form of either deep discounts on the final product or unusual items that can’t be found anywhere else. Pledging to support any crowdfunding campaign is a gamble, but it’s an exciting gamble; just browsing Kickstarter is pretty exciting, in fact, especially in the technological categories. Inventive individuals and startups offer new twists on machines like 3D printers and CNC machines – often for much less cost than others on the market.
  • Open Standards and Open Source
    Much has changed in the telecommunications industry in the years since Standards Development Organization (SDOs) such as 3GPP, ITU and OMA were formed. In the early days of telecom and the Internet, as fundamental technology was being invented, it was imperative for the growth of the new markets that standards were established prior to large-scale deployment of technology and related services. The process for development of these standards followed a traditional "waterfall" approach, which helped to harmonize (sometimes competing) pre-standard technical solutions to market needs.

  • The Voicemail Scammers Never Got Past Our OpenBSD Greylisting
    We usually don't see much of the scammy spam and malware. But that one time we went looking for them, we found a campaign where our OpenBSD greylisting setup was 100% effective in stopping the miscreants' messages. During August 23rd to August 24th 2016, a spam campaign was executed with what appears to have been a ransomware payload. I had not noticed anything particularly unusual about the bsdly.net and friends setup that morning, but then Xavier Mertens' post at isc.sans.edu Voice Message Notifications Deliver Ransomware caught my attention in the tweetstream, and I decided to have a look.
