Multiple Sites Driven By One WordPress Installation

This is early experimental. And, I’ve also marked this post into the “personal” category, because you wouldn’t want your clients to have too much access, especially if they share a single WordPress installation. Now I know there’s the WordPress MU project, but I guess I can’t use it in this case, because WordPress MU assumes your URLs will be within the same...

Working With Amazon EC2: Tips & Tricks

It’s been a while now since I’ve been hosting on Amazon Web Services and I’d just like to point out some issues I had and quick ways of solving them. We’re gonna talk about setting up a server that would serve not only you, but your clients too, cause $100/mo is quite expensive, isn’t it? So let’s begin and keep this as straightforward as possible. If you...

Foller.me: MySQL Tweaking & Optimization

As I mentioned in the interview with @enked on his website Chidimar.com, I had serious problems with MySQL database optimization on the Foller.me project. The current public stable version (beta-1) is using the MyISAM engine and it’s not holding much data – profiles, locations, geo points for the followers geography. In the new version (currently dev-1 and hopefully beta-2 in a few...

Have You Tried the Amazon Web Services?

Amazon EC2, EBS, S3.. I’ve been looking for the perfect web hosting for over two years now. Is this it? A few months ago I really liked MediaTemple cause they offered pretty good US hosting starting from $20/mo, which was quite good for the Foller.me project, so at the starting point I chose them. Their service is cool, definitely worth the money, but. A few weeks have passed, along with...

Linux Dummy: Unscheduled Maintenance

If anyone of you have tried to access the blog yesterday night, you might have noticed that nothing was working. Sorry! I’ll say it straight, it’s completely my fault. Yesterday evening I decided to set up a cron job for automatic backups on my VPS – a full MySQL dump and a compressed archive of the www directory. So I got a couple of error messages stating that I don’t...

Internet Connection Sharing Via Wi-Fi On Fedora Linux

I was very tired yesterday evening, so I thought about tweeting through my iPhone while lying in bed. EDGE is pretty slow and expensive, and 3G hasn’t yet arrived in Moscow (military issues) so I decided to go with Wi-Fi. Good idea, huh? And it took me just a couple of hours to set the whole thing up. I’m running Fedora Linux 10 but you should’t have much trouble on other...

Gone Mobile: SSH Terminal on Your iPhone

I was in a bus today in the morning standing in a traffic jam, when I suddenly got a call from my colleague Alex. He said that he messed up something in our database on my virual private server and didn’t know what to do because everything stopped working. Alex doesn’t know what SSH is and how to work with Putty so I had to figure this out all by myself and fast. Luckily I found...

Benchmarking: Your Web Hosting is Not That Perfect

Today I realized that the VPS I’m renting for $20/mo is not as good as it seemed at first. Ever thought about high loads? Okay, this may sound like some DDoS hacking tools, but no! 100 requests with 10 simultaneous made my virtual private server think for ~ 1,5 minutes. Jeez! It took me quite some time to find good software for running some load tests on my webserver, linux has some good...

Three Linux Commands You Can't Live Without

Okay, we’re not going to talk about the shutdown, yum, etc. commands, though THEY are probably the ones that nobody can live without. I’m talking about the web here, remember? And we all know that not everybody owns a VPS, a VDS or a dedicated server. Virtual hosting plans are quite cheap today, and most of them are tuned to provide you with SSH access and basic privileges (although I...
