Even though referer spam isn’t something new to black hat SEOs, WordPress blogs seem to get hit pretty hard with referrer spam these days.
Every time somebody clicks a link on a website, the browser sends the originating URL (the URL of the web page that hosts the link) to the target web server. This referer information can be parsed with web server log statistic software to show the webmaster where the web site’s visitors originated from. Continue reading “How to prevent referer spam”
On my last trip to NYC I noticed that my Nikkor 18-200mm (27-300mm) zoom lens wasn’t wide enough for quite a few locations. I was looking for a non-fisheye, ultra-wide lens for some time when a fellow pointed me to the brand new Tokina AT-X 11-16mm f/2.8 zoom, that’s 16-24mm on my Nikon D80. The same model is available for Canon DSLRs too. The lens is a DX which means it should be used on crop sensor DSLRs only. The quality of the lens body is very good, nothing feels cheap or flimsy.

I finally found the (almost) perfect tripod for me. I decided to go for the Benro HVC Flexpod C-298n6 with a Benro KS-0 ballhead for the following reasons:
- Lightweight (legs made of carbon fiber)
- Extractable/reversible center column
- Maximum load of tripod and ballhead is 8kg (17.4 lbs)
- Maximum height is 167cm (65 in.)
- Fits into my travel gear (folded: 54.5cm/21.5 in. + ballhead height)
- Affordable price tag (for a full-height carbon tripod)
The weight of the tripod including the KS-0 ballhead is just 2.4kg (5.2 lbs) which is lighter than my previous aluminum tripod which didn’t even have a ballhead.

A few months ago I wrote an article about uneven iMac displays. Apparently, some buyers, represented by Kabateck Brown Kellner LLP, were disturbed enough with the bad display quality of the aluminum iMacs that they choose to file a class action lawsuit against Apple. The lawsuit names inflated claims, concealed inferiorities of the new 20-inch iMac as main reasons.
See here for the official press release from KBK.
Personally, I’d love to be part of this lawsuit because the 20″ display in our iMac really sucks big time and it’s the reason why this iMac is the worst Apple product we’ve ever owned.
Today, my Holux M-241 GPS Logger was giving me a hard time. I wanted to connect it to my Macintosh over Bluetooth and the BT747 Java application for the first time. There’s some fragmented information on the Internet about how it can be done but I was unable to find a useful guide. Continue reading “How to use the Holux M-241 on the Mac over Bluetooth”
