Code Magazine Introduction to Mongo Article

MongoDBRecently I wrote my first article for a publication. What an experience that was. Writing on a blog almost no one reads has much less pressure than writing for a magazine that actual has a readership. The article itself was relatively easy but I learned my fair share for the editing process, which I need to write up later. In the mean time, here is the link to my article.

Php And Mongo Db Web Development Beginner’s Guide

Php And Mongo Db Web Development Beginner's GuidePhp And Mongo Db Web Development Beginner’s Guide by Rubayeet Islam
My rating: 4 of 5 stars

This was a great book for those looking to get their feet wet with MongoDB. PHP And MongoDB covered many more topics than many of the MongoDB books I have read recently and while I am not a PHP developer gave me a few more ways to leverage MongoDB in my day to day work.

I especially enjoyed the chapters on Geospatial functionality and the GridFS system. Both of these topics we handled throughly and are typically glossed over in other books.

The one place I felt this book was light was the operations and administration side of things. Nowadays, many developers are handling operations as well and I feel that those topics could be explored further in books like this.

All in all, I would recommend anyone in web development looking for somewhere to start with MongoDB pick up this book and give it a read.

Seven Databases in Seven Weeks

Seven Databases in Seven Weeks: A Guide to Modern Databases and the NoSQL MovementSeven Databases in Seven Weeks: A Guide to Modern Databases and the NoSQL Movement by Eric Redmond
My rating: 4 of 5 stars

Seven Databases in Seven Weeks is a great book for giving you an overview of the latest databases in the different segments out there. It is definitely an entry level chapter on each system that will let you know whether or not to pursue it further with more in depth material.

Anyone curious about what is available besides the de facto SQL standard offerings should give this book a read.

Sometimes You Have To Go Backwards

Your metrics are showing a decrease in performance and users are starting to complain. You start digging through the performance metrics, source code and your stack to find inefficiencies and places you can gain that performance back. What if you do not find any low hanging fruit and solutions are going to be invasive, complicated and time consuming? While those things may need to be done, do not just dive in and start the surgery, stop and ask who am I doing this for?

Humans are driven by numbers. Why do you think there are some many top 10 lists, 5 easy steps to be a guru, etc? Most developers just start attacking the problem with the goal being to get those numbers back in an acceptable range. Maybe they through up some caching, rewrite some queries or upgrade a server. Ultimately they get the numbers back into that arbitrary acceptable range, wrote some fancy code and might have wasted their time.

Yes, I said wasted their time. We need to step back and look at more than the performance numbers. Look at the analytics for your app. What does the actual user usage look like? How does that data looked when overlaid on your performance metrics? Look for the patterns and correlation of the datasets. The insight you gain might surprise you and point you to where the real problem lies. If you find a rarely used feature(s) seriously consider removing them. You may be surprised how one such feature can bottleneck the system.

Removing a feature that is causing a table lock or extreme CPU spikes can free up those resources allowing the rest of the site to flow and  with the usage data you can assess how valuable that feature really is. If you can’t decide one way or the other, ask your users. At the end of the day you may need that feature but your users can live without it for increased performance while you work on a better long term solution.

Don’t be afraid of throwing that hard work in trash. While it may seem like your app is moving backwards what you are really doing is improving your user experience, code and performance maintainability and doing so with the right combination of data to back up this decision.
