The correct abbreviation for the Conference on Neural Information Processing Systems is NeurIPS.

I think this could be said for many technologies: the cashier scans barcodes, the cook at McDonalds flips burgers when the alarm goes off, the anesthesiologist or pilot watches gauges...

davito88 | 9 years ago | on: U.S. motor vehicle deaths see biggest two year jump in over 50 years, per NSC

Ah. FARS does include data for each crash and each victim. It can be a mess to dig through: https://github.com/wgetsnaps/ftp.nhtsa.dot.gov--fars

Also, California has their own database that includes all crashes in the state down to crash/victim level: http://iswitrs.chp.ca.gov/Reports/jsp/userLogin.jsp (You have to create a free account)

There are other datasets too: http://opendata.stackexchange.com/questions/1755/automobile-...

All 50 states (and territories), only fatal crashes, goes back to the 1970s: https://www-fars.nhtsa.dot.gov/Main/index.aspx available via ftp or here: https://github.com/wgetsnaps/ftp.nhtsa.dot.gov--fars

All California crashes, fatal to no injury, goes back a few years at least: http://iswitrs.chp.ca.gov/Reports/jsp/userLogin.jsp (You have to create a free account)

Overall these data sets have been pretty well studied for the past few decades. The results are well documented: e.g. 6pm to midnight is the deadliest time, young males are the riskiest, older drivers are also risky, etc. Weather can actually be good for safety because people often drive slower and there are fewer cars on the road in bad conditions. But yes, weather can be a factor too.

Yes. The data is from the US Census Bureau's American Community Survey: http://www.census.gov/data/developers/data-sets/acs-5year.ht...

Here is the script to generate the GeoJSON file: https://github.com/davidbailey/py/blob/master/walkbike2015.p...

Thanks for the info about attribution. I've updated the page.

davito88 | 15 years ago | on: Ask HN: Is an SSD worth an upgrade for the 2011 MBPs?

SSDs are sweet. I just got a 13" MBP 2.7Ghz w/ a 128GB SSD. It's a screaming machine. Everything works instantly and it makes my older 2.4 Ghz MBP look like a sloth. In my opinion it's totally worth it. I spend a lot of time on a computer.

However, if you want a bigger drive than 128GB, I'd get a hybrid drive. You can get a 500GB hybrid drive for around $100. You get lots of space and I've heard they get around 80% of the performance gain of an SSD.

Enjoy the new laptop!

I love that this hit the HN RSS. However, I prefer the Pittsburg Left: http://en.wikipedia.org/wiki/Pittsburgh_Left

i've always thought password authentication is not the best way to be doing auth for websites. certificates seem to be the right solution, but difficult for the user to manage. (i love certs for ssh.)

davito88 | 15 years ago | on: Poll: How often do you visit HN?

I subscribe to the RSS feed. Pull it every hour. I guess that's 24x a day...

davito88 | 15 years ago | on: Poll: How much do you trust Google?

A while back I wrote an article talking about how Google has more information on you than any other single organization (government or corporate). Sure it's Gmail, search, ads (tracking cookies), but it's also maps, Chrome, Android. I'm just terrified Google is going to merge w/ the federal govt. jk http://www.davidabailey.com/index.php?title=The%20Internet%2...
