Hah!

Maybe we can change our tagline to be: "sales tool to know which of your customers are alive"

Lyft has this feature (not sure if they added it in the latest update) but the last time I rode the driver was unfamiliar with this feature and asked me "where to", to which I said I added the destination and as soon as the driver marked the ride as "picked up", the destination popped up in the maps. The driver was surprised and didn't know this feature existed.

Out of curiosity, does the Lyft driver app have maps/nav in-built while Uber does not ?

Congrats sam! Look forward to great things from you @ YC.

Does this mean you will have less time to write blogs ?

We are building a generic ETL framework and would love to talk with you about this. My email is on my profile.

great feedback. I was also skeptical of using EMR hive due to the fact that it is so far behind in versions. Also RedShift can do the analytics part very well but I don't think it can do the exploration part that Hadoop/Hive are so good at (but maybe I am wrong)

Thanks for your reply and your thoughts on the different frameworks.

Totally agree about giving better options to dev quickly in java too. There are so many times when I just end up using python to dev quickly and make a proof of concept web api and then when I have to interface with JVM systems, I end up writing thrift interfaces to keep my original python code around and to allow me to do quick changes to the api.

I tried dropwizard and it really makes it easy to write a webapi and is really fast. With that said, I will play with Micro very soon and let you know how it went.

This looks cool. Will give it a try soon. One comment I have is regarding the jars in the github repo, would you not benefit by using some kind of repository to pull down the jars when compiling (eg. sonar, maven central, clojars etc.) and remove all those deps from there and allow users to use their modified versions if needed. that will also reduce the size of your repo.

Also have you looked at dropwizard (http://dropwizard.codahale.com/) it's really simple to use. Would like to know your thoughts on that and also how your framework compares to theirs.

I agree with your points that PostgreSQL (or RDMS in general) is really good for certain type of reporting / analytics use cases while hadoop/hive is awesome for handling billions or rows + TBs of data.

How was your overall experience with impala ? Did you guys have a fairly new hive cluster to try it out or did you just spin up a new one since impala can only read certain file formats (i.e. no custom SerDe).

Also, for hive/hadoop datasets, is that more for just data exploration, while this PostgreSQL solution is for smaller datasets which return in a few seconds and would not perform well in hive due to the cost of setting up a mapreduce job ?

In addition to what others said, when you want to analyze multiple datasets the biggest problem is to store all that on a single machine or even a machine with network-attached storage. Eventually you will start hitting the bounds of I/O which is what big data tries to solve by moving processing units closer to the data storage (in theory).

In short, not all problems are big data problems.

aahh!! now i know why my application submit button would work sometimes even after i had the browser open for a few hours. Now I know that whenever it didn't work I could have been a victim of this restart.

thanks for the info.

I saw the HUD on the most recent BMWs and though it seems like a cool piece of technology, I am not sure if it's something that I miss sorely. Don't get me wrong, I was definitely wow'd when I saw it but in the end the amount of information that can be displayed without distracting the driver is limited. I am sure someone can prove me wrong but I have not come across it, not yet.

Given the amount of used cars that are sold every year, and the way people get wow'd by such technology, I would say it's worthwhile to build a SDK and at the same time provide an example of how to make a DIY HUD, if you get a lot of traction you can always make custom HUDs that users can buy directly from you (kickstarter project).

thanks.. i am sure there is some kind of agreement to not give out information on what he is talking because the liveblog is also not updating anything.
