Last year Google released WebM as an alternative to h264 encoded video. They followed that up with the release of WebP as an alternative to JPG. Ever since the release I’ve been thinking about giving it a try on iOS to see how well it might work to reduce application size. As a bonus to reduced size, WebP also supports an alpha channel that JPG doesn’t (there is more information available on the o
One of the first things I needed to do while building the GeeQE iPhone application was process the CC data dump from Stack Overflow. The dump contains XML files representing tables from Stack Overflow with the largest file being posts.xml weighing in at 1.2G as of September. I decided it would be pretty easy to use Ruby to parse the XML and load the data into MySQL so I went about finding the righ
This is for those who may want to load a video onto their iPad with iTunes that isn’t in the correct format. I needed to do this because I was trying to put an iTunes University video on my iPad a couple days ago and iTunes complained that it wasn’t in the correct format for the iPad. I’m not sure exactly how that could be but I decided to take the opportunity to see if I could use HandBrake to ea
The Google Analytics Dashboard plugin for WordPress gives you access to your Google Analytics data directly inside your WordPress blog. You can also allow other users to see the entire dashboard while they are logged in or include just parts of the data in posts, as a widget or as part of your theme. Goal tracking is also available. Dashboard Integration: Post Integration: Embedding Stats in Posts
I've been playing around with the Ruby/Rails cloud provider Heroku a little bit lately just to try it out. It is somewhat like Google App Engine or Microsoft Azure in the way it works since you bundle your application and push it out to the Heroku cloud for deployment. It is very easy to get things going but I ran into a few interesting items that I figured I would share. Some of the following gre
This post should be seen as a proof of concept. I’m working on creating a more concise and easier to use package of everything covered here but I felt like getting the knowledge out sooner rather than later would be of help to people looking for a way to do this. If you are interested keep an eye on the HTTP live video stream segementer and distributor project page as well as the github git reposi
This project is an attempt to make it easier to set up a live streaming server using Apple’s HTTP Live Streaming protocol. The source includes a ruby script and a C program that use FFMpeg to encode and segment an input video stream in the correct format for use with the HTTP streaming protocol. You can find the source in the git repository at github. For some background on this project you may wa
After some more work I have enhanced the HTTP segmenter and uploading script from my iPhone streaming using AWS S3 and Cloudfront post. I added a number of features and tried to pull together some of the ideas from the comments. I’ll go over some of the features here and there is a full list of configuration options on the HTTP Live Video Streaming server project page and the source is available a
I generally don’t recomend using SOAP instead of REST but I have been required to use SOAP so much now that I think it is inevitably going to be a requirement for a long time for certain projects. So when I noticed a question on stack overflow about using SOAP on the Google App Engine I thought it might be a nice exercise to see how easy it is to get fringe toolsets to work in the GAE. I’m going t
This has been done before with PHP (AJAX upload progress meter for PHP) etc but I needed something a little different because I wanted to upload a file and then have it loaded into a database. I looked around and found that someone had already made something that used the commons file upload package to do the upload part (AJAX Upload progress monitor for Commons-FileUpload Example). It wasn’t exac
After multiple attempts to find a good free diagraming application I think I have found a decent solution. I’m not creating enough diagrams to justify buying something expensive and I don’t feel like finding a graphics designer to make Dia diagrams prettier. If you have a Mac you are probably not in as bad a situation since you can buy OmniGraffle for $79. But for those of us without a Mac or who
I’ve been doing a little C programming lately and I have found that if you have a up to date distribution of linux there are a lot of libraries out there that make doing things you do in other languages like java easier. As I have time I’m going to post some examples of what I have found. The first here is how to base64 encode a chunk of memory using OpenSSL. [code lang=”c”] #include #include #inc
