ScienceLogic embeds MySQL in its EM7 network management appliances. An installation of EM7 can perform over half a billion database queries daily, storing massive amounts of data for both real-time and trended performance reporting.
Michael McFadden, senior software architect with ScienceLogic, will discuss all this in an upcoming MySQL webinar.

Month ago I was on a vacation and as usual even though our hotel provided us with an internet connection on a pretty decent speeds, I wasn’t able to work there because they’ve banned all tcp ports but some major ones (like 80, 21, etc) and I needed to be able to use ssh, mysql, IMs and other non-web software.
After a short research I’ve found a pretty simple to set up and easy to use approach to such a connection problems I’d like to describe here.
First, you’ll need someone (or you can do it before leaving home) to start an ssh daemon on port 80 on one of your servers. I use one of my Slicehub slices for this to permanently have an ability to use it. You can do it like this (if it is a temporary solution):

# `which sshd` -p 80 |
Notice: this `which sshd` was used because on some OSes sshd does not want to start w/o an …
[Read more]Many people know me as a nginx web server evangelist. But as (IMHO) any professional I think that it is really rewarding to know as much as possible about all the tools available on the market so every time you need to make a decision on some technical issue, you’d consider all pros and cons based on my own knowledge.
This is why when I received an email from Packt company asking if I’d like to read and review their book on Lighttpd I decided to give it a shot (I usually do not review any books because I do not always have enough time to read a book thoroughly to be able to write a review). So, here are my impressions from this book.
First, when I received the book, I was in doubt: how such a small book could cover so flexible and multi-purpose piece of software like …
[Read more]Since the day one when I joined Scribd, I was thinking about the fact that 90+% of our traffic is going to the document view pages, which is a single action in our documents controller. I was wondering how could we improve this action responsiveness and make our users happier.
Few times I was creating a git branches and hacking this action
trying to implement some sort of page-level caching to make
things faster. But all the time results weren’t as good as I’d
like them to be. So, branches were sitting there and waiting for
a better idea.
Few months ago my
good friend has joined Scribd and we’ve started thinking on
this problem together. As the result of our brainstorming we’ve
managed to figure out what were the problems preventing us from
doing efficient caching: …
Today I’ve managed to finish initial version of our bounces-handler package we use for mailing-related stuff in Scribd.
Bounces-handler package is a simple set of scripts to automatically process email bounces and ISP‘s feedback loops emails, maintain your mailing blacklists and a Rails plugin to use those blacklists in your RoR applications.
This piece of software has been developed as a part of more global work on mailing quality improvement in Scribd.com, but it was one of the most critical steps after setting up reverse DNS records, DKIM and SPF.
The package itself consists of two parts:
Question: Do you think you have what it takes to take a service from a few hundred thousand users to tens of millions of users in 1 year flat? If you do read on and perhaps become the next beloved scalability rockstar of our age.
We are looking for a data charmer. A mysql magician. A code hack. A funny man. A mad man. A passionate man. Or perhaps a woman who does all these things and more.
Here’s what you gotta do:
If you’ve ever worked in companies with 5-10+ servers and it was your responsibility to install new boxes, change some configuration files and install new software on many boxes you definitely know how painful this work is. Every time you need to change something on 3-5-100 boxes, you go there and make those changes. Most experienced of us used some weird scripts to perform some task on many boxes or used some stuff like dsh. Even with those tricks I’d never wish this work to anyone.
While I was working in Galt, I’ve asked our junior admin to check out puppet and try to use it on our servers. After a week of screaming he’s managed to install and configure it and …
