But they could. And it would be a good exercise to reflect on the fact that, should any or all of them disappear, no user would have any legal or practical recourse. I started thinking about this situation a few years ago when Tumblr—a platform devoted to a highly streamlined form of blogging, with an emphasis on easy reposting from other accounts—was bought by Yahoo. I was a heavy user of Tumblr at the time, having made thousands of posts, and given the propensity of large tech companies to buy smaller ones and then shut them down, I wondered what would become of my posts if Yahoo decided that Tumblr wasn’t worth the cost of maintaining it.

How to Quickly Extract Media from Slide Decks. If you’ve ever wanted to quickly extract the media (images, etc.) from a presentation such as PowerPoint or Keynote, there turns out to a pretty simple way to do it.

How to Quickly Extract Media from Slide Decks

This may well be common knowledge, but, as my friend Merlin Mann likes to say, every day somone’s born who’s never seen The Flintstones. That is, it’s always new to someone–and this was new to me. The key is to recognize that PowerPoint and Keynote files are basically just bundles of other files–that is, they’re fancy ZIP files: So if you want to find an easy way to pull photos, videos and sounds out of a PowerPoint or Keynote file, follow this simple tip:Make a copy of your original file (this way, you don’t risk harming your original). On your copy, replace the .PPTX or .KEY extension with .ZIP instead (do this in Windows Explorer or Finder – on a Mac you may need to open the Get Info window and then change the extension in there). Recommendations for timeline tools? Oddly enough I'm actually building a timeline tool for the Intro to European History I'm teaching this fall.

Recommendations for timeline tools?

Basically I'm going to crowdsource a European timeline between 400AD-1700AD in the classroom. I've looked a few things - yes, SIMILE is great and the de facto standard. But as an historian the date handling rubs me the wrong way - perhaps I'm reading the code wrong, but it requires a valid JS Date to work. The 14 Best Data Visualization Tools.

The 14 Best Data Visualization Tools

Raw data is boring and it’s difficult to make sense of it in its natural form. Add visualization to it and you get something that everybody can easily digest. Not only you can make sense of it faster, but you can also observe interesting patterns that wouldn’t be apparent from looking only at stats. Tool Buffet. VoiceThread.

First Reference Ontology for Plant Biology. The Planteome Project, an international collaborative effort that is Powered by CyVerse, recently has announced the first full release of their database and ontology browser.

First Reference Ontology for Plant Biology

The browser serves as a centralized portal where common reference ontologies (structured, controlled vocabularies) for plants are used to annotate gene expression, traits, phenotypes, genomes, and genetic diversity, across a wide range of plant taxa. The Planteome Project is funded by the National Science Foundation and leverages infrastructure provided by CyVerse to develop data standards and reference vocabularies that can be used universally to describe plant gene and phenotype annotation.

With numerous institutional collaborations, the project's goal is to aid scientists in developing improved plant genotypes leading to agricultural crops capable of delivering higher yields and withstanding climate pressures.
