Creating a snap using make or autotools

This probably isn't the right place to ask, but I thought I should ask in case it does matter in the context of snapping: when creating a snap of say, a hello world program in C[1], should I use the make or autotools plugin? Is one better than the other when it comes to snap creation? A quick

Re: Relationship between snaps and containers, if any

Thanks Mark, your explanation is clear. But I am also thinking along similar lines to Gustavo's suggestion of running a snap multiple times, and wondering if that is the same as having multiple docker processes. -- Luther On Wednesday, January 25, 2017 10:13 PM, Gustavo Niemeyer

Re: Version numbers for snap packages

I totally disagree. Use Gaussian integers for your major version number and transcendental numbers for the minor. The product of these must not lie in the range between a pair of twin primes, unless your using the ratio of a circle's circumference to its diameter, the base of the natural

Version numbers for snap packages

Hello all, Quick question about version numbering (as in, the `version:` field of `snapcraft.yaml`). The logical choice here is to use the version of the app being packaged, but what's the recommended way to handle changes to the snap package alone that don't change the version of the

I'm not exactly sure how functional it is in the snapweb package, but you can see that snapweb does package and use avahi to provide the ability to type a mdns address into a browser to get to the snapweb store by default: https://github.com/snapcore/snapweb On Wed, Jan 25, 2017 at 12:29 PM,

Re: Relationship between snaps and containers, if any

Interesting.. I actually don't see that line between snaps and Docker. Just like you can run "docker run mysql" several times, one may run "mysnap.mysql" several times. In both cases the daemon will be visible to the external world via a separate port of the local host's public IP address. In both

Re: Relationship between snaps and containers, if any

The best way to think of this is to know that snaps are GREAT when you have a precise 1:1 relationship between "machines" and "running instances". And Docker is GREAT when you want an elastic relationship. So for example, if you want a MySQL "appliance" on a device, there will only ever be 1

Hi Luther! Docker containers and snaps are different but sometimes overlap in solving certain classes of technical problems. For instance, "software distribution" as a broad problem is addressed by both snaps and Docker containers, but with very different implementations. First of all, yes you
