What happened to google search?

Google search is acting really weired recently. First off, my homepage disappeared from the search results by using keywords "Pan Yu homepage" (without the quote marks), which used to be the second results on the first page, but now totally disappeared (I haven't found within the first 10+ pages). Instead, lots of other web pages which neither contain consecutive "Pan Yu" nor are homepages of any sort are listed. At the beginning, I was wondering whether this is caused by the "personalized search" just launched, though I don't remember enabling it. I logged out my google account, searched again, nothing changed. Then I asked my labmate Edward to try the same thing for his homepage. This time, more counter-intuitive thing happened. When he typed "edward sim", his homepage appeared at the end of the first result page, however, trying "edward sim homepage" returned irrelevant stuff as what happened to me.

I know google has integrated news results to the normal search results a moment ago, but apparently what listed for our homepage search are not news. Google is acquiring a lot of companies and participating lots of other services outside the search world. While it used to move cautiously, it is more aggressive nowadays. I'm a little worried about google because it used to be based on pure technologies and people are really admire the objectiveness and spirit behind this. Growing into an empire that dominate the web may not be bad, since a lot of innovations and good services really benefit everybody and change the world. But except all those services and the so called google operating system, I really hope the heart of google can always be the same, being dependable and reliable, moving solid moves.

Tips

Do not try to compile a large program not compatible with your current version of gcc, instead, compile a version of gcc compatible with the program, and then use the gcc to compile it. (however, newest gcc does not even compile the old versions. In this case, compile a not-that-old version which compiles the old version to compile the old version. What a mess!)

Directional magnetic recharging

Daydreaming in the restroom just now, I was thinking how wonderful this world has become because of the discovery of electrocity. Electrical power captivated inside small batteries enables countless portable and handy applications, yet charging batteries frequently is really a headache and more and more becomes a bottleneck for all portable devices. I was wondering if there is any way to make recharging easier... here comes the idea. As we all know, electric power and magnetic power are interchangable. While electrocity conduction usually needs solid/liquid media like copper wire, the conduction of magnetic power can be done in the thin air. According to this simple fact, one can construct a pair of transmitter-reciever devices to transmit power from the power grid to charge the consumer device. The transmitter connected to the power grid convert electric power into a highly directional and focused magnetic beam, and the reciever obsorbs the magnetic beam entirely and convert it back to e-power to charge the device battery. Apparently one prerequisit needs to be kept: there mustn't be any living obstacles between the transimitter and reciever, to avoid harmful effects due to human body exposed to strong magnetic field.

Imagine a fuel free country with wirelessly rechargable transportations. Think of recharging recharging ur laptop on a bus, in ur car, etc. How amazing things would be.
