Although I'm very interested in the subject matter (I have a production site that uses MongoDB and AWS), I often find presentations like this incredibly annoying to read.
The problem is that presentations are short-form jot notes that are meant to be supported by a delivery as well. The vast majority of the value comes from what's not written down.
What's worse is that the "signal to noise" ratio detracts from my ability to understand what you're really going on about.
Some examples:
You say "MongoStat is Amazing" why? how? what does it do? (I've personally played with and used it a little, but I'd like to know why you're amazed by it. How can the things you've learned improve my practice?
You mention starting with 1.2 - does that mean you're not using 1.8? I've used 1.2 and was suffering 80% - 99.9% CPU load, as soon as I updated to 1.81 the load dropped to closer to 0.03% for most of the same operations. Does that mean your talk is invalid? Obviously there's a lot more to your story that I can get from your slides.
All things considered though I'm no trying to come off as a jackass. Normally when I see a HackerNews->slidedeck I just get frustrated and annoyed by things like the "inside joke" and "cute kitten slides" that rely on the speaker to deliver some insightful punchline. In this case I did read one or two interesting points.
Though I find I'm still suffering from the signal-to-noise problem that accompanies all these decks, this was better than most. I'd love a bit more narrative around the points that matter and a bit less around things that don't (how to query in mongo isn't really necessary in a story of why you abandoned it, is it?)
Anyways - was that a rant, review or stream of consciousness?
TD;DR Thanks for the slide deck; I hate slide decks; Yours was less terrible than most.
- schmichael 15y ago(I'm the speaker) Audio should be coming, but I'm not sure it will help. I definitely tried to pack way too much into a 45 minute talk. Not sure how to explain mongostat further... have you run it on a loaded server? Just a great little near-real-time stats tool. Like vmstat for a db. It could probably have a talk all its own just to explain how to diagnose performance issues with it. Most of my comments apply to MongoDB 1.4 although our little bit of data that remains in MongoDB has been upgraded to 1.8 (via 1.6 first). I've never had MongoDB use a significant amount of CPU load (from 1.2 - 1.8).
