GitHub Is Undergoing a Full-Blown Overhaul As Execs and Employees Depart
mattydread23 writes: This is what happens when hot startups grow up. [GitHub] CEO Chris Wanstrath is imposing management structure where there wasn't much before, and execs are departing, partly because the company is cracking down on remote work. It's a lot like Facebook in 2009. Business Insider has the full inside story based on multiple sources in and close to the company.


Docker Images To Be Based On Alpine Linux
New submitter Tenebrousedge writes: Docker container sizes continue a race to the bottom with a couple of environments weighing in at less than 10MB. Following on the heels of this week's story regarding small images based on Alpine Linux, it appears that the official Docker images will be moving from Debian/Ubuntu to Alpine Linux in the near future. How low will they go?

Really? You've never heard of Docker? Docker is a system that allows you to build "containers" for an application that contain all of its dependencies. Then you can deploy it on a machine where it runs as a VM, using its local copy of software and configuration if there is one, or the host's copy if not. It allows you to package applications that can run on any compatible server without interfering with other applications on that server. When you need to spin up a new machine, you can just copy the container over and the application and all of its configuration is automagically moved. It's awesome.

In the short term, Docker is going to change the way that every Linux system is administered. It will change the way that every Linux application is deployed. In the longer term, Docker will finally fulfill the promise of "write once, run everywhere"... linux, unix, windows, android; it won't matter any more. Docker is going to change the world.

In other words, its nothing new, but now with new added lack of security oversight because administration is hard and therefore worthless in todays race to the bottom.

The novelty comes from having a lot of tools to quickly maintain images and such. As you say, there's also 'dockerhub' to let you download canned application complete with OS libraries. The former I find to be handy, the latter I find problematic.

On the one hand, it can be a handy resource to dive into something to have a hands on example as you learn to deal with it yourself.

However, a few big downsides:
-Some projects have gotten very lazy about packaging. They make a half hearted or no effort to offer up distro packages, because 'hey, docker!'. I suppose this wouldn't be so bad, except for...
-As you say, these are various images with varying degrees of discipline in applying updates.

Complicating matters that even if you 'trust' a particular publisher, docker's infrastructure isn't exactly thorough about things like signing images and such. Updates become gigantic, because you are updating the entire OS even if one library needs a hand.

There's one guy working on a project called Atom/Atomic/Atome or something, which is basically your app compiled in to an OS container, instead of being built on top of an OS container, but still responding similar to a docker container.

Maybe several people doing the same, but this is one such project: http://www.includeos.org/

Simply add one include in you C++ project and compile it into a VM image.

I've been running linux as my main OS on my personal computers for about a dozen years. I browse through Slashdot nearly every day. I have never heard of Docker. I work in a Windows world and don't do application development. I'm not sure why you think this would be on the radar of every single reader of Slashdot.

This failure to explain, or even link to an explanation, of the core concept of a summary is probably one of the biggest recurring editorial failures on Slashdot. (And yeah, that's saying something.) Technology has a lot of specialized branches. I know plenty of application developers who don't know anything about networking, or network admins who don't know anything about databases or writing code, etc. etc.
