Thrift, Protocol Buffers, and Avro are modern software projects which all contain an IDL-enabled data serialization format with Python support. One might think that because they all have an IDL that they all would enforce some level of type safety even in Python, but one would be wrong:
Docker is a long-lived daemon process with a thin CLI client which makes it easy to
clone() new processes with their own PID namespaces, network interfaces, root filesystem, mounts, and hostname.
image contains a filesystem tree (actually an
aufs filesystem which allows one image to be implemented as a "layer" on top of another more "base" image).
Dockerfile is a list of instructions for building a docker image.
A short overview of terms used by the system that Amazon Web Services (AWS) uses to manage user accounts, roles, permissions and groups:
To get shared folders to work in VMWare Fusion with a Linux guest, I needed to reinstall vmware tools:
I couldn't get my home directory to work over hgfs (lightdm would log me in and then the session would immediately exit), so I created an entry in /etc/exports on my mac.
Ansible is a python command line program. In its basic usage, it reads a list of server hosts (the "inventory"), has access to a library of command line scripts ("modules") that might be run on the servers, and reads a configuration file ("playbook") which specifies modules to run on each server, and parameters to pass to each module. Using the sequence defined in the playbook, it connects to each server with SSH, copies (SFTP or SCP) the module up to the server, executes it remotely, then deletes it.
As is wont with modern open source software projects, the librarian-puppet homepage describes itself in terms that only fully make sense after you already know what the software does:
Librarian-puppet is a bundler for your puppet infrastructure. You can use librarian-puppet to manage the puppet modules your infrastructure depends on, whether the modules come from the Puppet Forge, Git repositories or a just a path.
If your computer crashes while firefox is running, it's possible that you will get an error message like this when you next start up firefox after rebooting:
Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.
To fix it, you can remove the lock files inside your profile. On Linux (with a default setup where you have a single firefox profile) this looks something like:
tig and GitX are invaluable for visualizing the git commit graph, but when GitX recently stopped displaying branch names on a repository I work with, I started looking for a stock git install command line replacement for two reasons:
Here is a command line that provides similar commit graph visualization:
