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).
Hi Guys, Today I wanna talk about a storage service that I have been using for a couple of months and I am pretty satisfied so I thought of sharing my experience with you guys. It's a Mega cloud storage that provides 50GB data for free and an official Linux client. Here is all that I have to say after using Mega in my Ubuntu Linux.
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.
Reddit: Kickstart vs Bare Metal Imaging - how do you decide which one to use? (what factors do you consider?)
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
- 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.submitted by /u/idioteques
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.submitted by /u/Arsoul
