After all the rave reviews of my last post I knew you were just on the edge of your seat waiting to hear more about my little unsupervised text anomaly detector. So, we’ve got some working ML! Our job’s done right? ‘Round these parts, it ain’t shipped ‘til it’s fast and it’s got it’s own chat bot. We spend all day in chat and there’s a cast of characters we’ve come to know, and love, and hate.

A wild anomaly appears!

So, I’m working on the new Data Team at Stack Exchange now. Truth is we have no idea what we’re doing (WANNA JOIN US?). But every now and then we come across something that works a little too well and wonder why we haven’t heard about it before. We run a niche job board for programmers that has about 2900 jobs on it this morning. Quality has been pretty easy to maintain.

I work at Stack Overflow on Careers 2.0. In addition to our job board we have a candidate database where you can search for developers to hire. Our candidate database has 124K+ developers in it right now. Customers frequently gawk at this number because they’ve looked at other products in the dev hiring space that offer millions of candidates in their databases. Sourcing.io claims to have “over 4 million developers” in their database.

So, we just went through comp review season here at the Stack Exchange. This is pretty much the only time of year we talk about money, because that’s the way we want it. We pay people enough to be happy and then shut up about it. You’ll probably only ever hear stuff about comp from me around September each year because that’s the only time it’s on my mind. The system works, and I’m generally happy about my financial situation, but we have a comp policy about remote work that subjects me to a bit of a perverse incentive when it comes to commuting.

So, calculating π is a fun pastime for people it seems. There are many ways to do it, but this one is mine. It’s 12 lines of code, it wastes a lot of electricity and it takes forever to converge. {% codeblock lang:csharp %} public double EstimatePi(int numberOfTrials) { var r = new Random(); return 4 * Enumerable.Range(1, numberOfTrials) .Select(o => { var x = r.NextDouble(); var y = r.NextDouble(); return Math.

Geography's The Fuck.

Raganwald poses an interesting question. Why do some of the best minds in our industry spend time figuring out how to make people click more on ads? Aren’t there more interesting problems for these bright up-and-comers to spend their valuable time and insight on? One simple answer to the question is Geography. How do you know this? I’ve spent a little time figuring out how to make people click more on ads :)

So me and my wife had a babby recently. Unfortunately my wife had some preterm labor around week 33 and we had to spend about 10 days in the hospital. Don’t worry, everything turned out all right (see perfection below), but I was pretty burnt out after the 10 days in the hospital. My wife was happy with my performance during our mini-crisis and she told me to go indulge a little.
