Conditional redirect based on use case from work.

Page a.php is moving to b.php, and b.php is not yet ready, but for some reason (well, we'll assume there is a reason) it is necessary to direct users to b.php to tell them that the new content will be hosted there, and then send them back to the original content at a.php without redirecting them again to b.php.

This is one way to do it in php. We introduce a query string parameter on the request to a.php that - if present - will force the content to load with 200 response; otherwise it 302 redirects to b.php. When b.php is completely ready it will be turned into a permanent 301 redirect.

(In reality a.php and b.php live on different domains but this example adapts easily to that case - and you could replace the query string condition with something else, like a referal domain check or other.)

Example of slanted row layout.

Two examples are given - the first only works if the width is fixed, the second is responsive.

Essentially following this answer:

https://stackoverflow.com/questions/12514197/convert-a-git-folder-to-a-submodule-retrospectively

Looking at the docs for git filter-branch is useful too:

Creating the submodule

First, create a cloned copy of your directory

Building production on a mean.js stack application

By mean.js I mean specifically an application based on the meanjs framework hosted here.

For reference, the following posts helped me identify and fix my problem.

• https://stackoverflow.com/questions/24516497/how-to-deploy-mean-js-node-js-application-to-production-environment
• https://blog.dylants.com/2014/11/19/bundling-production-assets-for-mean-js/

It works mostly like how you would expect. From a vanilla working development environment, the following should work:

Git log alias

This short but sweet post shows how to create a simple command to create an alias to a suped-up git log.

It's just a one-liner

$ git config --global alias.lg "log --color --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit"

A very basic Apache set-up to host python apps with mod WSGI

This is almost all taken from (https://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide) - I'm adding something here because I did not realize that I had port 81 blockked on my firewall and lost a bit of time figuring that out (was able to wget the expected url but could not navigate in a browser). Anyway, here are the basic steps. See the link google code link though.

In my case, I have an already running php server where I just want to test out some python web apps and don't particularly care about performance or anything like that. In reality, it might make sense to have a separate instance of apache running for the python apps. But that's beyond the scope of what I'm trying to accomplish today, which is just to get a hello world python app up and running.

1. Install mod_wsgi: sudo apt-get install libapache2-mod-wsgi
2. For this installation we will run python apps on a different port, namely port 88. It is not necessary to do
