How Trackback Works

No comments:
How Trackback Works is not very helpful. I will attempt to explain (and hence understand) a little more clearly, starting from first principles. Briefly a weblog is a stream of textual entries. The main blog page collects those entries chronologically with a cutoff. However, sometimes people might want to tell a friend about a particular entry. That's what "permalinks" are for.

There is no way for a blogger to know who's sharing permalinks, they just see a bunch of hits.

What if you want someone to know you're writing about them? One way is to leave a comment with a link to your own article. In fact, its not clear to me why this doesn't solve the problem. Trackbacks are often displayed right along with comments! The only difference I can see is that the Trackback interface is presented to you by your own blog, whereas leaving a comment uses various blog interfaces. Ah, there is one very powerful reason to do it - it presents a good way for you to leverage your effort for both your own blog and help others. A comment only appears "there" whereas Trackback appears here and there. It serves to collect your "output" in one place (e.g. everything I write on the web is collected in my blog.)

Aren't we just recreating Usenet.

Blogger Buzz pointed out that there is a new Rich Text BlogThis! thingy available via the google toolbar. That's good. Now if only they supported categories...

HTTrak Website Copier - Handy!

Back in the day I used to use a tool called "page suck" (or something like that). Now there's a quite sophisticated tool to download sites (quite handy for reverse engineering) called HTTrack. Recommended

The Iranian president is an idiot

No comments:
There really isn't any better way to put it. According to the BBC, he is hosting a debate on the holocaust. This is a little like hosting a debate on evolution - there is nothing to debate.

Luckily I am not the only person in the world who can put together 3 important facts to come up with a conclusion:


  1. Iran has huge oil reserves, and needs nuclear power like it needs more sand.

  2. Iranian president Mahmoud Ahmadinejad hates Israel and the Jews.

  3. The timing of the statements and the nuclear ambitions is rather close.



Conclusion: Iran wants to build a bomb to nuke Israel, and perhaps the US or Europe if it gets the chance. No-one is buying what Mahmoud is selling, thank God.
