Using Transloadit for file uploading & processing on your website

by Cliff 2. November 2013
Over the years I have used a variety of custom solutions to resize images, encode video, etc.  Transloadit provides a really nice cloud based solution that you can use with any technology stack.  From rails, to php, to JavaScript, you can interface with their API to upload images and videos.  They offer some easy to use plugins to help get you started https://transloadit.com/docs#jquery-plugin

Ruby 1.9 and Rails 3 Changes

by Cliff 28. October 2010

The following are some changes I recently came across when updating a rails 2.x plugin to 3.x.

 

  1. Default HTML Encoding or Escaping behavior has changed (XSS prevention).  Now, in order to not have your <>'s encoded, you can use <%= raw ... %> or "<div>".safe_html

Ruby on Rails Mysql::Error: Unknown system variable 'NAMES': SET NAMES 'utf8'

by Cliff 11. January 2009

If you receive the following error message Mysql::Error: Unknown system variable 'NAMES': SET NAMES 'utf8' when trying to run MySQL with ruby on rails it may be due to the version of MySQL you are running.  I was receiving this error when running a basic ROR app as well as when trying to run a migration rake db:migrate.

Turns out I was using MySQL version 4.0.12-nt which is not supported with the most recent version of rails. 

 I had MySQL 5.1 running on a different port, so I also needed to update the database.yml file to specify the port.  If you need to specify a MySQL port with rails, you need to add port: to the yml file...mine ended up looking like: 

  host: localhost
  port: 3307

 With those changes in place, I was then able to run my rails app and migrations.

Software Development Podcasts

by Cliff 22. May 2008

Below is a list of software development podcasts, IT Podcasts, and general computer related podcasts. Please add commnets on podcasts you enjoy...

.NET Rocks - This is a really good (quality and content) podcast that focuses on .NET development.  While the main focus is .NET there is a fair amount of content that applies to general computing and development such as design patterns, agilie practices, and more.

Software Engineerig Radio - This podcast provides an excellent variaty of topics that span technologies, languages, platforms, methodologies, etc. The shows can be rather technical and geared more toward knowledgable developers, but still offer a wealth of knowledge for beginners through experts.

Hansel Minutes - This is a weekly podcast that is primarily focused on Microsoft technologies but also includes other technologies and topics from time to time (for example digital photography).  While Scott is a Microsoft employee, the cast is rather open to non MS technologies and techniques such as TDD, ALT.NET, etc.

The Java Posse - This is an excellent podcast focused on the Java language, platform, and related technologies.  It provides both technical information as well as news and events within the Java community.

Buzz Out Loud - This is a daily podcast that is a summary of news and events relating to technology.  The personalities of the hosts really help to seperate this podcast from the usually news recap type shows...certainly worth checking out...

Polymorphic Podcast - A good podcast focusing on development and .NET.  The podcasts sometimes include screencasts and overall provides a lot of good content.

SSWUG - A database centric podcast dealing mainly with SQL Server but does include topics on other RBDMS as general database best practices.
