npm
As part of installing phantomjs when buoilding a development environment for Magento 2 I encountered a problem where it failed to install. The error presented to me was Error: Command failed: tar jxf /usr/lib/node_modules/phantomjs/phantomjs/phantomjs-{version}.tar.bz2 I was able to run tar, and tar was in my $PATH, so I was confused about the problem. Turns out because the file was a bzip one, it was trying to execute bzip2 within tar, hence why it seemed like tar was failing.

lxc
LXC is great, I’m really loving it. However I also love Fedora and work almost exclusively in the Red Hat, Centos, Fedora ecosphere - so the Ubuntu centric nature of LXC is sometimes a bit of a hindrance. One thing is that the LXC implementation on Ubuntu and Fedora differs in how the commands are run, eg Ubuntu: lxc start -n containerName and Fedora: lxc-start -n containerName This means that I can’t easily use the LXC bash completion I found here I love bash completion, it’s awesome and really quite easy to get working Here is something quick I threw together for working with LXC on Fedora: #!/usr/bin/env bash _lxc-containers(){ local cur local -a toks cur="${COMP_WORDS[COMP_CWORD]}" toks=( $( ls /var/lib/lxc | grep "$cur" )) COMPREPLY=( "${toks[@]}" ) return 0 } complete -F _lxc-containers -o nospace lxc-start complete -F _lxc-containers -o nospace lxc-stop complete -F _lxc-containers -o nospace lxc-attach I also use the following aliases to make life a bit easier: alias lxc-start="sudo lxc-start -n " alias lxc-stop="sudo lxc-stop -n " alias lxc-attach="sudo lxc-attach -n " And now if I add both of the above to my ~/.bashrc file, I get completion on start, stop and attach.

lxc
If you are finding that when you run lxc-checkconfig then you will probably get output like: Kernel configuration not found at /proc/config.gz; searching...

xdebug
Recently while trying to set up XDebug and PHPStorm for remote debugging I came accross the following error: cannot Accept External Xdebug Connection: Cannot Evaluate Expression '$_server['server_port']' I managed to fix this error by adding the following to my nginx.conf: fastcgi_param SERVER_PORT $server_port;

nginx
When specifying Nginx config, a common requirement is to control access to particular routes or even servers and use IP addresses as the method of restriction. Generally that’s quite simple, you can just allow 123.123.123.123; for any IPs you want to allow and then conclude with deny all; However - what if you have quite a large range of IPs to block - do you need to do a separate allow for each line?
