Installing SSHPASS

SSHPass is a tiny utility, which allows you to provide the ssh password without using the prompt. This will very helpful for scripting. SSHPass is not good to use in multi-user environment. If you use SSHPass on your development machine, it don't do anything evil.

Installing on Ubuntu

apt-get install sshpass

Installing on OS X

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

//How to validate selectize.js comboboxes with the jQuery validation plugin
//selectize.js: http://brianreavis.github.io/selectize.js/ (brianreavis/selectize.js)
//http://jqueryvalidation.org (jzaefferer/jquery-validation)

//configure jquery validation
$("#commentForm").validate({
	//the default ignore selector is ':hidden', the following selectors restore the default behaviour when using selectize.js
	//:hidden:not([class~=selectized]) | selects all hidden elements, but not the original selects/inputs hidden by selectize
	//:hidden > .selectized | to restore the behaviour of the default selector, the original selects/inputs are only validated if their parent is visible
	//.selectize-control .selectize-input input | this rule is not really necessary, but ensures that the temporary inputs created by selectize on the fly are never validated

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

Info

This guide sets up a non-clustered Nutch crawler, which stores its data via HBase. We will not learn how to setup Hadoop et al., but just the bare minimum to crawl and index websites on a single machine.

Terms

• Nutch - the crawler (fetches and parses websites)
• HBase - filesystem storage for Nutch (Hadoop component, basically)
