Five Hidden Dangers of Facebook (2010-05-08), from CBS news, at Source

I noticed today my webhosting company truncates IP address in the weekly weblog.

For example, in daily log, a entry would look like this:

196.12.236.55 - - [17/Apr/2010:00:00:00 -0400] "GET /favicon.ico HTTP/1.1" 200 217 www.xahlee.org "-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Creative ZENcast v2.01.01" "-"

But when they generate the weekly log by combining the past 7 daily logs, they replace the last part of ip address by “x”, so it looks like “196.12.236.x”.

Not sure why they are doing that. It wasn't so before. My webhoster is 1and1.com.

Anyone knows why? it's not by law is it?

Discovered that Wolfram Alpha generates a link graph for your site. See for example: http://www.wolframalpha.com/input/?i=xahlee.org.

This is quite useful when you need to know quickly a site's link topology. Am pretty sure there are better sites that generates a better link graph. If you know, please let me know.

Just discovered, that someone tried to trademark the term “SEO”. It appears, a chick named Rhea Drysdale stopped him, together with USD$17 k out of her pocket. See her blog on this incidence: SEO Trademark Registration Terminated (2010-03-15), by Rhea Drysdale. Source.

I think that's a commendable deed.

Quite amusing. Quotes from Content-control software:

Content-control software has been cited[14] as one of the reasons Beaver College decided to change its name to Arcadia University , as content-control software had been blocking access to the college Web site. Another example was the filtering of Horniman Museum.[15]

Quotes from Scunthorpe problem:

The problem was named after an incident in 1996 in which AOL's dirty-word filter prevented residents from the town of Scunthorpe, North Lincolnshire, England from creating accounts with AOL, because the town's name contains the substring cunt. Years later, Google's filters apparently made the same mistake, preventing residents from searching for local businesses that included Scunthorpe in their names.[1]

Discovered http://www.chillingeffects.org/. A site that deals with conflict of interest on the web. e.g. “cease and desist” letters, copyright, defamation, DMCA, etc. Lots of useful and reliable info.

Discovered Mibbit. A web based application for IRC, Yahoo Messenger, Twitter. Written in JavaScript. I'll be trying it out in coming weeks. Note, you can't use mibbit with freenode.net's irc server, because they banned it.

I haven't kept up with web tech for implementing instant messages, which is quite important and became popular in the past 3 or so years, especially by Google Talk. I looked into it about 4 years ago when a client needs chat functionality on a web site, but at the time i looked, there are like 3 or so Open Source ones i found in the few hours i looked. Most are implemented with PHP, and they are all pretty lousy.

How make IE's webfeed button work. See bottom of: Introduction To Atom Webfeed.

Google introduced a new tool, Chart API. It lets you create many sort of charts and graphs. You need some coding experience to use it. Basically, you send a url to google's chart server (GET or POST request), the url is a little programing lang that contain all your data. Google than sends back a image of your chart. Very handy. I'll probably use it. Home page at: http://code.google.com/apis/chart/image_charts.html

Another thing google announced is Aardvark. Which lets you ask a question and get answers. Any question. Any, you might ask your friends, family, co-workers, teachers, colleges, on tips, how to, where, or questions in professional fields. Announcement at: Source. Home page at: http://vark.com/.

More juice from the google exit china threat, from The Wall Street Journal. Google Warns of China Exit Over Hacking (2010-01-13) by By JESSICA E. VASCELLARO, JASON DEAN and SIOBHAN GORMAN. Source

The article gives a bit more detail on the nature of the hack, google's revenue in China, google search's market share in china. Follow links on that article will be quite a few others... all over the web.

From Google's blog: A new approach to China (2010-01-12). Source

Google is saying that recently there's a sophisticated attack, originated from China, on gooogle china that seems to be focused on stealing info on Chinese human rights activists. And they are implying, that they might exit China business.

The article is overall negative on China. I'm Chinese by blood. If google bad mouths China, i wouldn't support google.

Google might exit China? That is quite a laughable suggestion. As a business, that's close to suicide, even with google's particular philosophy on business ethics (which i think is good). Also, it is not clear if this is just a blog-level bluffing drivel. A blog with implied suggestion of exiting business in china is one thing, but if they explicitly make a official statement to their stock holders, that'd be different.

China has several of their own huge search engines, video site engines, etc. Just like everywhere else, the competition is tough. Those Chinese web companies, as well as foreign companies running in china such as Yahoo and Microsoft, would be more than happy, H A P P Y, if google gets the fuck out of China.

As for google ending their search engine censor in China... that'd be great if they asked the Chinese government and gets permission. Ultimately, it is up to the Chinese goverment, the Chinese people, to decide.
