lat lon - Measuring accuracy of latitude and longitude? - Geographic Information Systems Stack Exchange
"The ninth decimal place is worth up to 110 microns: we are getting into the range of microscopy. For almost any conceivable application with earth positions, this is overkill and will be more precise than the accuracy of any surveying device.

Ten or more decimal places indicates a computer or calculator was used and that no attention was paid to the fact that the extra decimals are useless. Be careful, because unless you are the one reading these numbers off the device, this can indicate low quality processing!"

The Architecture that Helps Stripe Move Faster
Lots of good stuff here about switching gradually. Reminds me of how we rolled out Rails 4 at Swiftype.

Also, this gem: "Eventually they found that Eventmachine is unusually difficult to program against."

Residents Express Concerns Over News Reports Expressing Concerns of Residents — Nick Magrino
"Minneapolis is not Manchester during the Industrial Revolution, or Hong Kong or Dubai or even Manhattan. It's a city of 420,000 that used to have 520,000 people and has a lot of room to grow in a place that is probably a good long-term location for city, unlike, say Phoenix or Miami. What is the responsible story to cover here? A lot of controversy you hear and read about is kinda manufactured, which does not help. It would probably be good to think about the big picture."

So, about this Googler’s manifesto. – Medium
"I need to be very clear here: not only was nearly everything you said in that document wrong, the fact that you did that has caused significant harm to people across this company, and to the company’s entire ability to function. And being aware of that kind of consequence is also part of your job, as in fact it would be at pretty much any other job."

Research Blog: Extra, Extra - Read All About It: Nearly All Binary Searches and Mergesorts are Broken
Integer overflow affects many implementations of searching and merging huge arrays. By Joshua Blooch, 2006.

"The version of binary search that I wrote for the JDK contained the same bug. It was reported to Sun recently when it broke someone's program, after lying in wait for nine years or so."

How to Tell the Truth – Andreessen Horowitz
"[A]ny dishonesty from the leader will be devastating. Employees trust CEOs with their livelihood, most of their waking hours, and their careers. If employees are repaid with lies, how will they trust the CEO’s directions? As a result, how well will the company execute?"

HTTP requests in Python - michaelgalloy.com
"The “Zen of Python” provides the basic philosophy of Python. From PEP 20:

There should be one — and preferably only one — obvious way to do it.

I doubt there is a single area in Python that violates this more than making a simple HTTP request. Python provides at least six builtin libraries to do this: httplib, httplib2, urllib, urllib2, urllib3, and pycurl. There are several reviews comparing the various libraries."

The microservices cargo cult - Stavros' Stuff
"Verily, verily, I say unto thee, do not start out with microservices just because the cool kids are doing it, they’re the complicated way that you don’t need in the beginning. Enjoy the ease of development and agility of deployment that a single new app brings, and, when your business has been proven and growing and you can’t find servers big enough for it, only then split out parts of your infrastructure into their own services, connected by HTTP or a messaging queue."
