I got two of them from ebay recently at around $30 HKD each, the price is nice and the brightness is acceptable for soft illumination, the problem is that the light is closer to blue than white. The standard E27 interface worked out great.
Again, if you want them for soft illumination, the blue color is going to work.
I would say that cheap LED illumination technology is not yet ready. I wonder why, because it works pretty good for flashlight, and in that case, they're bright and truely energy saving.
I shall wait for another six months and longer to buy another small batch.

Refilling ink
Just successfully refilled the ink cartridge of my printer, the cost different is a kind of crazy, more than 60:1!!!
The ink was purchased online from DealExtreme, now one of my favorite shopping place, and I will always check the price there before heading outside, it's usually cheaper and better yet, it features site-wide free shipping.
There is no trick in re-filling ink, and the instruction inside the package is more than enough. I failed for the first time simply because that ink cartridge was broken originally, the print head was leaking, maybe it's too old or maybe I've handled it improperly before.
I've ordered a re-fill set for the color one as well, will do it later, but it seems the method is a bit different.

The old fashion way about downloading
Last night a friend of mine asked me to have a look on their internet connection, I did a ping and it works, and apparently, it was the browser which failed. Therefore, I proceeded to try Firefox, however, it was broken as well. So, how can I download another browser for them?
Yes, the answer is the old fashion ftp which is available even for command line!
Among all the browsers which I tried, only Firefox and also Mozilla still got ftp site which easy-to-guess name, i.e. ftp.mozilla.org
On (cleanly) removing the old Firefox and reinstall the new one which I just fetched from the ftp, it does not work still. So, I tried to install mozilla, and it works!
Afterward, I have also downloaded the google browser for them, just as a backup. But then it requires another browser first and in that case, it's mozilla.
As a summary, old fashion technology still has its place, especially when the new fancy stuff failed badly.

Source of noise from PC speaker
Some people reported that their on-board AC97 had noise, and I found a similar situation on my new PC. When you move your mouse, or when the hard drive begins to spin, you can hear the subtle noise, especially at night when the environment is relatively quiet. Therefore, I proceed to buy an external USB sound card in the hope to fix the problem.
However, the problem persists.
Then I know why, my speakers are drawing power from the USB port of the motherboard, and those were the real source of the noise. I tried to power the speaker from some other sources and the noise was gone!

Royal View Hotel
http://www.royalview.com.hk/chi/index.html
We just had a short local holiday there. In short, when you got only two days of holiday and you don't want to travel far away, finding a good local hotel might be a good option.
Near this hotel we have a beach, the water was no good in quality but if you're parents and you will know that all the kids wanted would be a beach so that they can play around the sand, digging here or there and building sand castle, etc. Therefore, there's no problem for the relatively bad water. Anyway, people still swim there but it's not recommended.
The food is nice, the restaurant was a small one but the variety and the quality of food is superb, they keep re-filling and changing food all night, even during the last half-an-hour. The price is cheaper than outside given similar quality, it is especially true if you go for their promotional packages during holidays.
The guest rooms are big in the standard of Hong Kong, and the view outside is unique and good. The swimming pool is nice and clean, with some toys so that your kids would enjoy. Finally, there are two playing rooms for the kids where you can find video games, indoor playing equipments, chess, boardgames, etc.
It's just wonderful to stay there for one night, simple and relaxing.

Stepmania and Economical Dancing Pad
In short, my kids (4 years old and 7 years old girls) enjoy it very much and it's just inexpensive and fun.
The USB dancing pad:

The software:

Zero complain, and actually, I've something similar many years ago but it was a parallel port version and the quality was just far worse. This one is USB (no driver required) and it is much better designed. Highly recommended for your kids.

Using the last drop of ink
I found that my inkjet printer was running of out black ink, there were nothing shown on the last few pages which I have printed, just a trace of black hint here and there, but it's definitely unreadable.
Last night, I pulled out the ink cartridge and clean the printing head with a tissue, after cleaning the mess, I inserted the cartridge again. And strange enough, the print out now is very good, and there's no trace of low ink as viewed from the printout. I don't know why, but it works. I believe this trick might be useful to squeeze the last bit of expensive ink from those original ink cartridge.
