Hello dear readers and attendees,

This is the post that I will be/ will have been referencing during my presentation to the Seattle Central Community College’s Byte club on Thursday, December 10th at 1500-1630.

I will begin with a bit of an autobio and find out what kind of students we have in attendance. Please feel free to comment if you’d like to keep in touch before or after the presentation. I will discuss some of the bits and pieces of some industry standard platforms which I’ve developed, deployed, maintained, managed, co-operated, administered and replaced. We can discuss some of the patterns that work well in the industry, and some that are a bit harder to tame.

Once we have touched most of the areas of specialization represented at the meeting, I will dive in to an AngularJS demo I am developing in github here:

As I reported via Twitter late last week, we encountered an issue that got some of our mail delivery delayed by about a day and a half. I’ll explain more about what happened as I believe in openness on these matters, and also the experience has educational content for others.

Our mail server doesn’t have direct external interaction, it’s shielded by two relays that handle both the inbound MX and the outbound queue. This setup works remarkably well in terms of exposure to spam and other malicious activity. As previously discussed, it appears that it’s more difficult to make mail server infra more resilient without expending lots more time/effort and infrastructure expenditure. Just because of the way the common tools for mail delivery and imap are built, having two or more of each in a semi-active setup gets quite complex. Complexity is in itself a risk so it has to be considered in relation to the costs and risks of the …

This post is being constantly updated as we find out more useful information on Momentum tuning. Last update: 2012-05-05.

About 2 months ago I’ve joined LivingSocial technical operations team and one of my first tasks there was to figure out a way to make our MTAs perform better and deliver faster. We use a really great product called Momentum MTA (former Ecelerity) and it is really fast, but it is always good to be able to squeeze as much performance as possible so I’ve started looking for a ways to make our system faster.

While working on it I’ve created a set of scripts to integrate Momentum with Graphite for all kinds of crazy stats graphing, those scripts will be opensourced soon, but for now I’ve decided to share a few tips about performance-related changes …

Just noticed that the Drizzle list has had more messages since June last year (2008) than the mysql internals@ list has had since March 2006.

I got a phone call the other day from someone asking about MaxDB MailDB. He said that he got my phone number from something he read online. I publish my phone number with a lot of my writings, as well as the url to *this page you're reading now*

So some people call me on it sometimes. I might have to put up an asterisk filter some time if I get too many calls.

He called me to tell me that MailDB is the new Jesus Christ and that I should *sell sell sell*!!!! (!!!)

He didn't put it quite that way, but that's the gist of the conversation.

I spoke with my manager about working on this code for MySQL during work hours. That means that any work I do on it belongs …
