Elliott C. Back: Internet & Technology

I just received an interesting email, which “offers” to help me secure my .com domain name in the Chinese varieties .cn and .hk. It’s more of a threatening piece of spam, because it carries the fear that if I do not avail myself of their services, them or another company will steal my brand!

Subject: YOUR DOMAIN NAME (elliottback)’S CURRENT SITUATION

Dear ELLIOTT C.Back

We are the domain name registration organization in Hong Kong, ,which mainly deal with the domain names’ conflicts of the company in China and Asia regions.We have received an formal application online from one company named “TianHaiYuanTong (China) Investment Co.Ltd” who is trying to apply for the domain names(www. elliottback.cn www. elliottback.hk etc.) and the Internet keyword(elliottback) as their domain name and internet brand on Oct 6,2008.After our initial examination, we found that the keywords and domain names being applied are the same as your company’s name and trademark. These days we are dealing with it. If you don’t know this company, we doubt that they buy these domain names with other aims. We have not started the registration for TianHaiYuanTong company until now. In order to deal with this issue better, please contact us by telephone or email as soon as possible.

Best Regards,
Boyce Meng

However, as far as I can tell, there is no such “Tian Hai Yuan Tong” company, and I am not replying. I advise you to do the same, and post any more samples of this spam in the comments!

If you’ve thought about whether upgrading from WP Cache 2.0 to WP Super Cache is a good idea, hopefully this benchmark will convince you. I followed my instructions on benchmarking Wordpress with Apache Bench on four configurations of this blog’s main page to measure performance:

1. Without any caching plugins
2. With WP Cache 2.0
3. With WP Super Cache (no compression)
4. With WP Super Cache (compression enabled)

The results show that WP Super Cache is a clear winner, performing 225% better than the older WP Cache. Here is the raw data I gathered during the test:

No caching:
Requests per second: 22.81 [#/sec] (mean)
Time per request: 4383.559 [ms] (mean)
Time per request: 43.836 [ms] (mean, across all concurrent requests)
Transfer rate: 613.75 [Kbytes/sec] received

WP cache:
Requests per second: 872.30 [#/sec] (mean)
Time per request: 114.640 [ms] (mean)
Time per request: 1.146 [ms] (mean, across all concurrent requests)
Transfer rate: 23549.46 [Kbytes/sec] received

Super cache (no compression):
Requests per second: 1518.90 [#/sec] (mean)
Time per request: 65.837 [ms] (mean)
Time per request: 0.658 [ms] (mean, across all concurrent requests)
Transfer rate: 41150.81 [Kbytes/sec] received

Super cache (compression):
Requests per second: 1960.39 [#/sec] (mean)
Time per request: 51.010 [ms] (mean)
Time per request: 0.510 [ms] (mean, across all concurrent requests)
Transfer rate: 53108.70 [Kbytes/sec] received

Normally I’d be uninterested in the story of how three New Zealand teen allegedly murdered 14 year old John Hapeta in New Zealand. According to the New Zealand Herald, “Two men charged with the murder of 14-year-old John Hapeta allegedly armed themselves with a revolver-style pistol and a claw hammer when they went to his house looking for drugs and cash. John Hapeta was celebrating his friend’s 15th birthday at his home in Justamere Place, Weymouth, when the attack occurred. Police allege the three went to John’s home on August 12 with the intention of robbing what they thought was a ‘tinnie’ house. The draft police summary of facts said Tumata and Williams pulled black bandannas over their faces and walked up to the house, confronted a man and allegedly shouted, ‘Where’s the drugs, where’s the drugs?’”

The story now becomes interesting when Judge David Harvey bans online mention of the accused’s names. No one is sure why print media (which is searchable, through interfaces like Lexis Nexus) gets special treatment here. I certainly disagree, and I’m free to publish whatever I’d like, as a journalist, including the names of the accused.

Anytime anyone wants to suppress totally free speech, I say RESIST!!
