The primary bottleneck is feature extraction, transformation and iteration, which is both CPU and read/write intensive. Model building is not too slow, so no need to distribute training/testing as of yet.

I've heard good things about Spark/Shark and Storm. Does anyone have any experiences or recommendations? Maybe we don't even need a super sophisticated system and a Riak/Redis K-V store cluster would do?

I want to set up an VM for my team. I am trying to use VirtualBox to run a local copy of production software environment on each laptop as that's what I believed to be the common practice.

However, if we try to give the env an initial data dump, it can easily boost the file size to >10G and makes setting up process very time consuming and for some machines that is even too big.

Because of that, my teammate set up a cloud-based env for himself and encouraged us to do the same. Even though it is creative and solves some problems, I am not sure if that's a good solution. Is it reliable? Is it scalable?

What will be your recommendation on setting up the Dev env?

Thank you.","time":1349192412,"title":"What is the best practice on setting up development VMs?","type":"story"}],[3679859,{"by":"krsgoss","descendants":6,"id":3679859,"kids":[3680567,3680250,3680013,3681346,3680006,3680678],"score":2,"text":"I'm planning on purchasing a new 13\" MBP this weekend.

My wife and I decided that for our anniversary this year we'd both get $100 to spend on whatever we want. I've wanted a nice set of headphones to use when coding/mowing/etc, but have yet to purchase any because I do not know which to buy.

A couple of guidelines: I like noise canceling, but that usually pumps up the price and I hate when headphones require an extra battery. I usually prefer over-the-ear headphones to earbuds, but I won't rule earbuds out.

Kind of an oddball question, I know, but the fact is that I respect you all's opinions quite highly especially when it comes to which tech to buy.

I appreciate any assistance you might provide!","time":1274880368,"title":"Ask HN: Any Headphone Recommendations For Around $100 US?","type":"story","url":""}]]
