HTML5 might helps slowness of Udacity's videos.

Recently I resumed studying programming on Udacity, starting with algorithm course.

However, the videos very often get slow and lag - I could't even recognize what was the sentence teachers said. Then I got to check what is wrong with that.

Chrome's task manager showed adobe flash player consumed many CPU capacity. I suspected that flash player, known for Steve Jobs hated it, is doing something bad while loading a youtube videos incorporated in Udacity.

And I ended up with finding HTML5 trial on Youtube. After turned off flash player and took HTML5,  the videos on Udacity got better except for occasional latency.

So, if someone has the same problem on Udacity, you might resolve it with changing flash player into HTML5 on Youtube.

bought discounted English books.

Today I got three paperback books at nearly half of ordinary prices, for the book store's closeout sale.

The first one is James Bradley and Ron Powers's real story mainly about aftermath of the historically famous picture, the rising flag on Iwo-Jima, "Flags of Our Fathers" for 600 yen.
The next is Lisa Randall's science book in the field of the cutting edge theory of modern physics, "Warped Passages: Unravelling the Universe's Hidden Dimensions" for 900 yen.
The last is Eric Abrahamson's "A Perfect Mess: The Hidden Benefits of Disorder" for 800 yen. I don't actually know even what is the main focus of the book. But the benefits of "mess" was pretty interesting for me, and the word made me take this book on the counter.

Those books are able to be bought on kindle or other tablets now, with low prices almost similar to those discounted books. But I found that real books have still advantage for browsing pages.
