What a horrible website. Made an account to get the mp3. Just to discover that the mp3 download link doesnt work even then. Thank god I used a throwaway email to sign up. Otherwise I would be even more pissed.
Disappointment in the HN community has reached a new high today.<p>So, instead of discussing the topics in the video, the majority of commenters here are discussing the flaws of the website it's hosted on or debating whether or not reddit is profitable. Neither of which has ANYTHING to do with scaling.<p>I expected better, people. Seriously.
"ask me anything about running a profitable social media company".<p>Except for that reddit is not profitable.<p><a href="http://blog.reddit.com/2013/08/reddit-myth-busters_6.html" rel="nofollow">http://blog.reddit.com/2013/08/reddit-myth-busters_6.html</a><p><a href="http://www.reddit.com/r/TheoryOfReddit/comments/1ihwy8/ratheism_and_rpolitics_removed_from_default/cb50c8c" rel="nofollow">http://www.reddit.com/r/TheoryOfReddit/comments/1ihwy8/rathe...</a>
I was confused about the memcached problem after moving to the cloud. I understand why network latency may have gone from submillisecond to milliseconds, but how could you improve latency by batching requests? Shouldn't that improve efficiency, not latency, at the possible <i>expense</i> of latency (since some requests will wait on the client as they get batched)? And while maybe efficiency is valuable, why would that be an improvement for a problem they didn't have before?
So did anyone else take the most important lessons in the video as:<p>1. Use AWS<p>2. Use Postgres<p>3. Use AWS<p>4. Use Cassandra<p>5. Use python, so later you can write C when shit needs to go super fast<p>That's what I got.
Thrilled to finally see this on InfoQ -- already an underappreciated resource for technical talks. What is it about video + slides that appeals so little to people?
Does anyone know how the different storage systems are utilized, and why each system is utilized for that purpose? The presenter mentions using memcached, Cassandra, and PostgreSQL, and mentions the same type of data when discussing each (votes, for instance). I would definitely benefit from a more in-depth understanding of how each system is utilized, and why.
