LXer: 5 steps for making community decisions without consensus

Wednesday 17th of August 2016 02:50:54 PM
Healthy open source communities usually include a wide range of people with different ideologies, goals, values, and points of view—from anarchists to CEOs of major corporations. The normal approach for making decisions that affect the entire community should be an attempt to reach consensus through discussion; however, what if you're attempting to make a decision that is critically important, but there are irreconcilable differences in the community?read more

TuxMachines: Basics Of Linux File Permissions

Wednesday 17th of August 2016 02:21:33 PM

Linux file permissions are very well documented in many places throughout the internet. In fact, it’s one of the first things one learns when first learning Linux. Linux permissions are the first layer of security when it comes to your personal files and folders, as they control who can access and/or change them (and in Linux, technically everything is a file, but that’s a discussion for another day).

Linux.com: How Twitter Avoids the Microservice Version of “Works on My Machine”

Wednesday 17th of August 2016 02:03:07 PM

Apache Mesos and Apache Aurora initially helped Twitter engineers to implement more sophisticated DevOps processes and streamline tooling, says software engineer David McLaughlin. But over time a whole new class of bespoke tooling emerged to manage deployment across multiple availability zones as the number of microservices grew.

LXer: Packaging Apps for Linux the Easier Way

Wednesday 17th of August 2016 01:32:58 PM
There are now at least three app packaging systems that pretty much ignore a distro's directory hierarchy and do away with the need to find and install dependencies, making them distro agnostic. They all work basically the same way, by including standalone copies of all libraries that would otherwise be shared within the package. This also does away with "dependency hell," which has plagued computer users since the advent of shared libraries.

Reddit: Kickstart vs Bare Metal Imaging - how do you decide which one to use? (what factors do you consider?)

Wednesday 17th of August 2016 01:29:10 PM

In my particular example, I deploy a "stack" to systems (around 2000) which are in groups of about 10 to 20 in different cities throughout the US. The stack is essentially identical, except for the typical host-identity configuration (IP, hostname, etc...) Once this image and minor tweaks are complete, the host should not have any additional configuration updates. (i.e. I don't keep a separate BMI for each individual system - it's the same BMI laid down on every system, then tweaked).

I am contemplating whether it is better to:

  • deploy the systems using kickstart (using PXE and http) and perform host-identity tasks during the kickstart and apply final tweaks post-install
  • or....
  • deploy the systems using an BMI (using PXE and http - and ReaR) and apply final tweaks post-install

My gut is telling me that kickstart (without a Bare Metal Image) is likely more flexible and just as adequate as the BMI approach. If I need to tweak something, I simply update the kickstart source vs having to deploy an image, update the image, recreate the image, upload the image.

Just wondering what you all consider when deciding which method to use.

Reddit: Battery Life

Wednesday 17th of August 2016 01:06:35 PM

This has probably been covered in other posts, however, the only thing that has stopped me from using Linux as my main OS on my laptop is battery life. I currently have a desktop using Elementary OS Freya and wanted to use the same on my laptop. I ended up booting into Freya, installing and testing it, I'm getting less than half the battery life that I do on Windows.

I understand that this is because of missing hardware specific or driver optimizations from the OEMs, but is there anyway at all to get close to the battery life one would expect running Windows? And I have already installed TLP and it seems to only increase it marginally.

Reddit: Is anyone having trouble with Kali and VMware tools?

Wednesday 17th of August 2016 12:52:25 PM

I am having the hardest time getting VMware tools or Open VMtools to work on a Kali VM on workstation player 12.

They both seem to install correctly, but the screen resolution is still messed up.

Any advice is welcome.

LXer: 'Top' Linux System Monitoring Tool

Wednesday 17th of August 2016 11:46:40 AM
Hello everyone. Once I used to be a Windows user but now I use ?Linux? and I use Ubuntu distribution. When I switched to Linux, one of the initial tasks was to know the processes running in the background. In Windows, we have task manager which is GUI. In Linux we have so many task managers that are GUI & CLI both. In this article, I’ll mention one of the easiest CLI Linux system monitoring tool known as ‘Top’.

  • 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.
