My kids (9-year olds) each got a Kindle for Christmas (thanks Gramma and Grampa!). It looks like even for them to “buy” free books, this is how I had to set them up:

  • Create an Amazon account for them
  • Manage Account, 1-Click Settings
  • Turn on 1-Click for the account
  • Add an address
  • Click the link to make it the 1-Click default address
  • Make this address the billing address

After this, my kids were able to “purchase” free books (and gift cards can be added to their balance), all without requiring a credit card number. Thanks, Amazon for making this so simple! 🙂

A simple vector image of a camera
I kind of forgot about the idea of writing in my blog so that I can find the answers again via Google. Well here’s a quick one: How to backup the entire contents of your webcam (I own a Sony HDR-XR150) to a “Camera Archive Folder” on OSX.

  1. Open up iMovie
  2. Go to “File > Import from Camera” or the click big camera button under the Project Library pane
  3. Click the “Archive All” button beside “Camera: Sony HDR-XR150”
  4. Choose a location to save the entire contents of your camera (I use portable hard drives)

After doing this, you’ll have a “Camera Archive Folder” where you can import movies into iMovie for your editing pleasure.

I want to believe. SVG as an image format.As promised, I have a tiny thing to announce here. I recently split off and refactored the code that deals binary data in kthoom into a new open source project: https://github.com/codedread/bitjs, Binary Tools for JavaScript.

The faster and faster JavaScript engines in modern browsers and the rise of new technologies like Typed Arrays, Web Workers, and the File APIs mean that browsers can actually be used to read in binary formats completely on the client-side (as long as native performance isn’t a requirement).

For now the library includes two main capabilities:

  • streams for reading in bits and bytes from a Typed Array
  • unarchiving zip, rar or tar files (that’s right, you can unzip and unrar in JavaScript now)

I want to believe. SVG as an image format.Oh, I forgot to mention a cool thing that happened at the beginning of the year while I was so busy: Wikipedia inched a step closer to having an in-browser editing experience for its impressive collection of vector image files via an experimental MediaWiki Extension. The extension was put together by Brion Vibber of StatusNet and WikiMedia fame. Fingers crossed for this to one day appear in Wikipedia! 🙂

I want to believe. SVG as an image format.I’ve been busy at my day job not launching code, but over the weekend I had some fun converting kthoom‘s unzip/inflate algorithm from using binary strings to using Typed Arrays. Typed Arrays mean native binary data that is accessible to JavaScript in the browser, making operations like unzip much much faster (like 4x). Read the rest of this entry …
