Interesting development in the Apple spellchecker conspiracy: The Cupertino effect

Searching the UN’s website, it seems like this still plagues them.

I don’t know how I missed this, but Roger Ebert recently wrote about the difficulties of being voiceless (since his stroke) and finding a speech synthesis replacement.

It’s great that, after making the transition from television to his blog, Ebert can still so throughly engage his audience.

There’s been some interest in U+2603 (a.k.a. the unicode snowman) on the web lately (perhaps spurred by this sighting on TechCrunch):

  1. Like Andre, Unicode Snowman Has a Posse now.
  2. Someone made a handy Unicode chart and dubbed it Unicode table for you.

☃ is honored.

Google’s normally pretty good at handling special cases, but attempting to search for nearby Escape from New York Pizza, leaves you kind of screwed.

The solution? Just search for “pizza.”

Martin D. Ginsburg, Ruth Bader Ginsburg’s husband, has a great sense of humor.

The second installment of “terms of art.”

context switch |ˈkɑntɛkst swɪtʃ| noun

The art

Computers can run more than one program at a time, yet many only have one CPU. Yet when I’m programming, I don’t have to include any logic about what to do if another program needs to take over for a while. How do modern computers manage this feat, then?

Whenever the operating system determines that a different process deserves some CPU time, it pauses the currently running program and resumes the other. This is called context switching. All of the registers on the CPU (encapsulating the entire state of the program) are saved in memory, and the other program’s registers are loaded into the CPU. Amazingly, this allows us to pause and resume programs as they’re running!

Saving and loading these registers takes substantially longer than a normal CPU operation, though. Despite this performance hit, context switches occur on the order of hundreds of times per second to maintain the illusion of multiple programs running simultaneously.

Out of context (no pun intended)

the cost associated with changing the task one is working on, usually referencing the time necessary to begin to be productive in the new task : after abruptly being pulled into the meeting, the engineer requested a few moments to context switch.

Some kind Wikipedia editor created this chart of “supranational European bodies,” which is, at the very least, impressive:

Inspired, I decided to create the analogous chart for my continent:

November 13, 1973:

AASHO’s Policy Committee approves a new name, “American Association of State Highway and Transportation Officials,” and a broadened mission and membership to include all forms of transportation. On November 15, George H. Andrews, Director of the Washington State Highways Department, is installed as the first President of AASHTO.

Uh-huh, surrreee. You changed your name because of your new mission statement, not because your previous acronym sounded like the perfect way to pronounce “asshole.”
