Reboot Your Brain with a Caffeine Nap

leave a comment »

Didn’t get enough sleep last night? Grab a quick midday nap just after a cup of coffee. From Wired’s How To wiki:

Scientists say that a successful midday nap depends on two things: timing and (no kidding) caffeine consumption. Experiments performed at Loughborough University in the UK showed that the sleep-deprived need only a cup of coffee and 15 minutes of shut-eye to feel amazingly refreshed.

  1. Right before you crash, down a cup of java. The caffeine has to travel
    through your gastro-intestinal tract, giving you time to nap before it
    kicks in.

  2. Close your eyes and relax. Even if you only doze, you’ll get what’s
    known as effective microsleep, or momentary lapses of wakefulness.

  3. Limit your nap to 15 minutes. A half hour can lead to sleep inertia, or
    the spinning down of the brain’s prefrontal cortex, which handles
    functions like judgment. This gray matter can take 30 minutes to reboot.

Test If Site Is Blocked in China?

leave a comment »

WebSitePulse is supposed to test for you if a website is blocked in China.
Enter any URL on top, select a location (if you want to test mainland
China, pick e.g. Beijing), and provide a verification code. After some
seconds you’ll get either an OK or a couldn’t connect to host message.
For instance, is supposedly OK whereas
is blocked. Note that sometimes what may be blocked in one region in
China mainland may not be blocked in another region in the country. I
can’t verfiy if this tool returns correct results, but if anyone from
within China knows more, please leave a comment.

Here are the results for my own site
