crorella··on 7.1 magnitude earthquake strikes Southern California
It was not lost right away, it was working for several hours, around 12, but with a very low pressure. Since this happened on February (summer time) we were lucky one of our neighbors had a pool full of water we used for the toilet :)

After checking the build quality of the places around here (SFO bay area) I'm getting concerned too.

Make sure to have a backpack with some essential items there. Have some gallons of water and make sure to have a plan in the eventuality of an accident, for example, make sure to close the gas main valve. Sync with your family on where to gather if they are at work/school, etc.

I was there for the 9.1 @ Chile in 2010 and all of this was super helpful, within 10 minutes my whole family was gathered in our parents house and we were already saving water in our bathtub and pans (which was super handy, because we had no water for about 3 weeks)

crorella··on Ask HN: What are you working on?
I'm working on implementing a few optimizations for our DWH, in particular I want to automatically find the best partition and bucketing schema for tables based on their access patterns. This is actually part of a much bigger project that I want to do to further increase the performance and efficiency of our data analytics systems.

Yeah, that too, after the fact seems so stupidly obvious.

Money saved by firing experienced engs and outsourcing the development << money lost because they can't sell planes.

Why is that so hard to understand? Massive fail at risk management maybe?

How do you deal with discoverability of map keys and struct fields? That's something we just added after such datatypes became more prominent in our DWH.

crorella··on Facebook Overhauls News Feed to Focus on What Friends and Family Share
They mention this quite explicitly: "As we make these updates, Pages may see their reach, video watch time and referral traffic decrease. The impact will vary from Page to Page, driven by factors including the type of content they produce and how people interact with it."

I think it's bold but good for the long term.

Hi, right now I'm processing my perm, in particular, the PERM application was sent to the DOL last September. I would like to know if there is any problem if I change jobs now. Will this cause delays in the process?

Thank you
