Dreamhost Deal Comes Back Again

   Posted by: techiecat   in Internet

A sweet dreamhost deal comes back again! Please see the image.

The same deal came into my eyes when I looked for a web site hosting company around the new year. I had already done some research on web hosting and dreamhost was on the top of my list. So I just took the promotion without hesitation. It has been one month, and dreamhost does not disappoint me so far.

If you are looking for a web hosting service, why not give it a try? It will cost at most 10 bucks anyway.

Note: my web site is a small, personal web site without much traffic. So I do not have experience with dreamhost for large, professional web site hosting. And I am not paid for writhing this article.

Insights of Web Feed Publishing and Tracking

   Posted by: techiecat   in Tutorial

As many web masters do, we can host our web feeds (or RSS, a more familiar word to you) on a third-party provider. I’ll share the interesting insights that I got during my recent adventure on web feeds. In this post, I supposed that you know something about RSS or ATOM (two most popular formats of web feeds) and want to know more tricks on how they are working. Especially, I will explore the following questions:

  1. First of all, who produces the RSS documents and where are they?
  2. How are your RSS recoganized by browsers automatically?
  3. What does a third-party provider, like Feedburner, do for you exactly?
  4. If you use a non-popular blogging system, how do you configure your Feedburner feeds?
  5. The third-party providers often show statistics such as how many subscribers you have. How do they got such number? Is that number accurate?
  6. Your feeds links look wired. Can you explain them?

So I decided to do a small test on it. I searched two practical questions that I had recently. Let’s see how well cuil and Google did on my questions.

When sued by a Pennsylvania couple after their home (on a private road clearly marked as private property) appeared on Google’s Street View pages, Google said that

Today’s satellite image technology means that even in today’s desert, complete privacy does not exist

Yes, I admit it’s true. But can we have SOME PRIVACY if we do not have all? At least, people will not see details of a house or a face from any public satellite image. While this is what Google is doing.

I actually use street view some time. It is not a bad or evil service from theory. But can Google do some extra efforts to respect our little privacy? Such as blur our faces on their images, or limit their street view cars in public places only.

Secure WordPress by SSL

   Posted by: techiecat   in Security, Tutorial, Wordpress

Using SSL protocol to protect your critical information, such as user name and password, is a good idea. If you may log to your blog via an unprotected wireless network or you make some directory (e.g. uploads/) writable by WordPres, you’d better use SSL (i.e. using https:// type URL) to encrypt the administration traffic.

If your WordPress blog is hosted by a web-hosting provider, the provider likely has SSL solution for you already. In this article, I would like to share my experience on SSL solution on a self-hosted machine, which use a Fedora system and Apache httpd server.

The best solution in WordPress is probably to use the  Admin SSL Plugin. However, it cannot set up everything for you. I will give a complete tutorial on how to make SSL work for you, including how to get a key and certificate, how to set up SSL module under Apache and how to fix a bug of the Admin SSL Plugin.

A Review of Online RSS Readers

   Posted by: techiecat   in Review

I was a little frustrated today, for online RSS readers. I used to be a happy woman with Google Reader. However, I found that Google Reader is slow sometimes. After I posted new posts and used ping-o-matic to update them, they just NOT showed up in my Google Reader, even though I could see the new posts in my feed link. The Refresh button is jusr useless! OK, so I said “it is the time to try a new online RSS reader”. I want to have an online RSS reader with similar interface as Google Reader which can retrieve new posts quickly. My little research is as blow.

One of my friends has a pixelpost-based photoblog on catsgarden.net. Pixelpost is a simple, neat and pretty platform for photo blogging.

Today he called me saying that he got a “Coming Soon! Nothing to show. No image to show here!” message when he visited his photoblog. “Did you change anything?” He asked. I did some maintain on the server, but I did not touch httpd server and anything inside his blog directory. And I did see images just in the images/ directory. What’s wrong with that? Searching did not provide any useful information for me.

Finally I found that the problem is the system time of the server. When I maintained the server, somehow the system time was accidentally changed to an earlier day. He did not post anything yet at that time. So pixelpost got no images from the SQL query – since pixelpost actually queries images before the current system time (this is what I read from the PHP code) by default.

Solution: after I set the system time correctly, the problem is solved :)

Nowadays, domian name is a cheap resource to make your web space cool. After you purchase a domain, most of the domain suppliers allow you to add sub-domains. Then, it is a good idea to provide sub-domains for your friends or your web sites with different styles. In Apache, you can serve multiple domains and sub-domains using one IP address. In this article, I would like to share my experience on setting up virtual host in Apache.

Scenario: We would like to set up name-based virtual hosting. We have two domains (domain1.com, domain2.com) and more subdomains. We want to serve them with one IP address. Our DocumentRoot path is docrootpath (you must replace with your real path).

Where to put .htaccess for permalink and the reason

   Posted by: techiecat   in Wordpress

Permalink is definitelty a good idea. When I tried to setup the permalink in my WordPress blog, however, I was frustrated at the beginning. I always got 404 error, mod_rewrite seemed not working. Finally, I found that it is really simple. I was just confused by a statement in the WordPress Document that
