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the Trends page for the library website (the old page is http://library.tc.columbia.edu/trends.php) which is really outdated (some data are for 2006-2007).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.
According to this post on Quora (answered by a former Google recruiter), NO!
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:
- Content is king
- Choose your words wisely
- Create a great user experience
- Go social
- Make use of video transcripts
- Leverage a multi-channel strategy
- Create sitemaps
- 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).
Two weeks ago we had a seminar about offering great customer support in Higher Ed. I really hope my story had happened before that day so that I could share it with everyone at the seminar. Anyway, here is my recent story to prove the old ways of customer support should die and social media should take its place.
I purchased a TCL HDTV from Amazon in 2010, which is a renowned Chinese brand but not so much in the U.S. Six months ago I was reviewing something else when I encountered the so-called "firmware update instructions" on Amazon. Unfortunately I did the update although I didn't have any problem with the TV. After that all my TV did was show me a black screen.
Unluckily my TV was out of the 2-yr warranty. Since I am a tinkerer-kind-of-person, I googled around hoping I can find a solution instead of paying $100+ to a service person. Nothing useful was found. So I contacted the TCL customer support via phone, which proved to be a waste of time because all they could do was to give me the number of a local service center. This was totally expected though because those outsourced support representatives do not know anything about the products.
A study conducted at Seattle Pacific University (SPU) uses Google Hangouts, Vialogues, and blog in an online course:
Quotes from student evaluation:
Vialogues was a convenient and useful method to interact with students if you were not able to attend the Hangout, still felt like I got to know classmates better that participated in the Vialogues even if they weren't getting to know me blog buddies: helped create a network of other educators who passed on helpful resources.
Hey, anyone still remember my earlier proposal to integrate Google Hangouts into Vialogues?

We have a flexible, adaptive physical environment that can be transformed for multiple purposes for education.
2) Participatory learning (intellectually and physically).
3) Flexible, adaptive physical environment and pedagogical content.
1) Projections on wall (modularized).
2) Sound-proof projector screens use the columns as anchors. They can be raised or dropped to divide the hall in different ways in order to create various configurations of immersive learning environments. For example, it can divide the hall into an exhibition space, or into several smaller classrooms.
3) Short-throw projectors cast images or videos on each of the those screens. What are projected can be controlled by the on-wall consoles (the purple rectangles).
When Nara reported what she learned in theÂ Fluent Conf 2013Â she discussed the benefits of using web icon fonts instead of image sprites. I was very interested in this new technique so gave it a try. The result was quite satisfying because with web icon fonts we can reduce download size of Vialogues Player by 15%.
The benefits of using web icon fonts instead of image sprites:
Reduce download size. Icon fonts are vectors. So they are potentially smaller than images if you have lots of them.
Easier to change. It is well admitted modifying image sprites is a huge headache because you may have to re-calibrate all other sprite icons every time you revise the size, location, or number of the sprites. Icon fonts, however, are relatively easier to modify -- not in terms of modifying the icon per se but other icons will not be affected.
Better display quality on hi-res displays such as Retina iPad. Because icon fonts are vectors, your icons will be always sharp and clear no matter where or how large you display them.
