Chinese Emperor Has 1.5 Million Direct Descendants

Qing Emperor, GiocanggaNo wonder the Westerners get the Chinese people confused all the time insisting, “You Chinese all look alike; you related?” A research based on genetic evidence reported by BBC News identified about 1.5 million men from north-east part of China and Mongolia were direct decendants of a single Qing emperor.

The article credits this incredible phenomenon to the fact that it was not unusual for the royalties of the time to have several wives and concubines. One peom I used to memorize for school romanticized an emperor’s indulgence in 3,000 concubines during the Tang Dynasty.

“Research into an unusually high prevalence of a particular set of genes in China has suggested that 1.5 million Chinese men are direct descendants of Giocangga, the grandfather of the founder of the Qing dynasty.”

No wonder the Qing Dynasty was in such bad shape in the 1800s. The emperors were too busy womanizing and smoking opium. And considering how “productive” Chinese emperors were throughout history, maybe there’s some truth in such stereotypical comments from the Westerners. To make matters worse, emperors used to behead not only the entire family of certain criminals, but everyone who’s related to that family in anyway up to nine degrees of separation, which could have easily translated into thousands of people. The tactic was used to prevent revenge from close relatives of the criminal in question. Sometimes this meant an entire family tree of the same last name disappearing forever from the face of the earth, which in turn explains why certain last names only exist in history books today.

Earth Browsing

I guess there’s a whole community of Google Earth enthusiasts out there sharing what they found with each other. Since the forum is hosted on Keyhole.com, the company that actually made the software that is now Google Earth, I guess it’s endorsed by Google in some fasion.

There’ll be a day when Google Earth is banned from some offices, much like chatting clients and personal emails in some companies are actively forbidden.

RHCE Links

As part of prepping my next “career move”, I was looking into getting a RedHat Certified Engineer certificate to match what my resume says I know. I found a site that has quite a number of useful links.

Having a fine art degree in computer art, worked in a (practically failed) education technology start up with a diversified (but not professional) knowledge in a bunch of stuff don’t really prepare me for any kind of position really. Everywhere I looked, people are looking for hardcore specialty expertise in one area or another, especially in Silicon Valley. Maybe our luck will soon run out as everything in the bank will be depleted in no time.

Everybody dreams of a beaufiful American Dream. But sometimes it’s holding on to the illusion of such dreams that’s hard to let go.

OSX Spotlight Hogs CPU

For the past couple of weeks, the fan on my PowerBook would just start spinning like crazy out of the blue. Checking the CPU usage didns’t really yield any satisfactory results. But I finally found the culprit — Spotlight.

According to Many Ayromlou, sometimes Spotlight does hog the CPU, most likely when it’s trying to index corrupted metadata. So I applied the fix suggested by the site:

1) Using the mdutil command-line utility in Terminal, turn off indexing for each of your drives. example:

1
$ sudo mdutil -i off /Volumes/<i>your_hard_drive_name</i>

2) Then use mdutil to remove the indexes from each drive

1
$ sudo mdutil -E /Volumes/<i>your_hard_drive_name</i>

3) Physically remove the .Spotlight directories from the root of each drive.

1
2
$ cd /
$ sudo rm -fr .Spotlight-V100

(do the same for your second or third drive) BE CAREFUL WITH THAT RM COMMAND! One typo could ruin your day.

4) Use mdutil again to turn indexing back on for each drive

1
$ sudo mdutil -i on /Volumes/<i>your_hard_drive_name</i>

5) Spotlight will now re-index all drives and should behave in a normal fashion. (No longer uses 60%-80% of your CPU)

As Spotlight tried to re-index my entire hard drive again, I snapped this shot…
Spotlight indexing

Even though it estimated 10+ hours to index all of 23GB of files on my hard drive, the actual time it took to index everything was more like 2 hours — a far more acceptable time.

All this was done while I was trying to feed Bryan, change his diaper, check my email, read the online forums from SCAD eLearning, browse through the news and send a homework-related mass email.
