I encountered the following video where a LinkedIn staff talked about the Economic Graph project at LinkedIn. After seeing this video and some digging about the EG project, it turns out EG is very similar to our own almost-forgotten project -- EdNode!

Yesterday I ran into U.S. Department of Education's Ed Tech Developer's Guide published in April 2015 and was excited to find New Learning Times was mentioned as a useful resource for EdTech developers nationwide!

New Learning Times is produced at the Ed Lab at the Teachers College at Columbia University and

I have spent a day to implement the Trends page for the library website (the old page is http://library.tc.columbia.edu/trends.php) which is really outdated (some data are for 2006-2007). It's very interesting to look at those stats but I think it's important to get the stats up-to-date. Right now you can preview the Trends page on the development server:

I attended this webinar titled Empowering YouTube for Higher Education today facilitated by 3PlayMedia. The webinar turned out not to have the content I was expecting. I thought it would be an overview of diverse use cases of YouTube in higher education but it eventually is a product demo from Justin McCutcheon, CEO of Cattura Video.

Tip 1: Optimize PNG and JPG with TinyPNG

If you frequently work with web images, particularly PNG or JPG, you should know this awesome tool: http://tinypng.com/. What this tool does is to reduce the size of PNG and JPG files by 1/3 to 1/2 without decreasing image quality to the eyes. I strongly encourage our editors and content managers to optimize the images with this tool before uploading them to NLT, Vialogues, Pressible, etc. By doing this users will be able to load our webpages faster.

It is extremely easy to use this tool. Simply drag the images (up to 20 images per upload, and 5MB per image) to the dotted box on their webpage, and you'll see your images get uploaded and shrunk. In case you have uploaded some wrong formats, TinyPNG will know that and show you an error. By the end you will have a download link for each uploaded image so simply download them.

I came across this whitepaper by JWPlayer — one of the most popular video player products in the market. Its title is 8 Steps to Master Video SEO and after reading it I find it's very informative and would like to share. The 8 steps this whitepaper mentioned are:

  1. Content is king
  2. Choose your words wisely
  3. Create a great user experience
  4. Go social
  5. Make use of video transcripts
  6. Leverage a multi-channel strategy
  7. Create sitemaps
  8. Mark-up with Schema.org

Among these steps, some we have taken for Vialogues, others not. And some of the untaken steps are ready to be implemented in our technology framework. I will be interested in hearing your thoughts.


  • On Vialogues, each vialogue and each video page should have its own meta keywords. Right now the adwords are all the same across the site (about EdLab and the Vialogues site per se but not the vialogue/video content).
