Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

# This file contains pin mappings for the Anycubic i3 Mega with
# Ultrabase from 2017. (This config may work on an Anycubic i3 Mega v1
# prior to the Ultrabase if you comment out the definition of the
# endstop_pin in the stepper_z1 section.) To use this config, the
# firmware should be compiled for the AVR atmega2560.

# See the example.cfg file for a description of available parameters.

Frequency Testing

This will allow you to test a specific frequency that you hear when you do your resonance testing in Klipper and potentially track down where extra peaks are coming from. If something is rattling at a specific frequency, you can specify that frequency and feel around the printer until you track it down.

Code was adopted by zifnab from somewhere in Klipper.

Usage

You have to have [resonance_holder] in your printer.cfg.

The command is HOLD_RESONANCE AXIS=<axis> FREQ=int SECONDS=<seconds>

###Creating a REST API using Node.js, Express, and MongoDB

####Installing Node.js

Go to http://nodejs.org, and click the Install button. Run the installer that you just downloaded. When the installer completes, a message indicates that Node was installed at /usr/local/bin/node and npm was installed at /usr/local/bin/npm. At this point node.js is ready to use. Let’s implement the webserver application from the nodejs.org home page. We will use it as a starting point for our project: a RESTful API to access data (retrieve, create, update, delete) in a wine cellar database.

Create a folder named nodecellar anywhere on your file system. In the wincellar folder, create a file named server.js.

Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:
