Assorted Web 2.0 Tools That Might Be Helpful

QR Codes

There is a plugin for the Firefox browser called Mobile Barcoder.  Once installed, you can automatically generate a QR code for the current page, and/or any link on the page (right-click, generate code), or select text on the page and generate a QR code for the text.


You can add Mobile Barcoder to the Chrome browser also, but it only generates a QR code for the current page.




Ripping audio (mp3) from a YouTube video?  When I am driving around, and have low bandwidth, videos pause frequently on my iPad.  I was listening to some TED Talks and realized that for some presentations, the video wasn’t necessary,  just the audio.  So I googled for tools and found several (the one below is online) that would rip the audio from a video.  The mp3 audio file is much smaller than the video, and usually will stream or play even in low bandwidth areas.



I’ve installed portable versions of my favorite browsers on a USB (flash) drive.  I added the Mobile Barcoder plugin.  That way, I can plug my flash drive into a PC, laptop or presentation podium in class, open my browser, and push QR codes to my audience (students).  That’s even if my school doesn’t have Firefox or Chrome installed.
