Looks great!
 
Estimating a causal effect accurately is hard, especially when a randomized experiment is not available. We've been working on this problem for some time at Google. One approach we've been developing and using internally is based on Bayesian structural time-series models.

We use these models to construct a synthetic control — what would have happened to our outcome metric in the absence of the intervention whose effect we're interested in. This approach makes it possible to estimate the causal effect that can be attributed to the intervention, as well as its evolution over time.

Today, we're excited to announce the release of CausalImpact, a new open-source R package that makes Bayesian causal inference in time series simple and fast. Visit the Google Open Source blog, linked below, to learn more.

Question for Software Developers: If you were to apply for a developer job, how would you feel if the employer asked that you take an online "quiz" consisting of some simple programming exercises? Would you find that it's kind of beneath you? I've had some applicants who refused. Not sure what to make of it.

I've given and taken these before.

When I give them, it's usually 6 "fill in the body of this function" problems, and it just differentiates those who can follow instructions and write a program from those that can't. Not one of the 15-20 people I've sent it to has ever refused. When people ask how they did, I give them my honest assessment of their code, comments inline. Because even if I don't want to hire them at that moment, it's better for everyone if they know how to improve.

Other tests I've taken have believed they were asking for more in-depth results, but which I determined to be a bit over the top. One gave 30 minutes for 10 questions, all online. I recently took a test that required building a basic app - backend using Python, Django, and MongoDB, along with a frontend that let you manipulate data using drag and drop. Hilariously enough, neither of those companies offered me a job... which makes me wonder: what the hell are they trying to hire for?

Want to learn how to make some cool things with 3D printing? The MIT Club of Southern California is hosting a workshop (limited to 15 people) at Deezmaker Hackerspace in Pasadena, Saturday 10/26/2013, 1pm to 6pm. 

I accidentally reserved an extra spot -- I thought I was I updating a registration, but instead it created a brand new one. So I can take another person. It's $75. Let me know!

  
Event Description - Learn 3D Printing - Repeat event (Pasadena). Have you been wondering what this 3-D printing excitement is all about? Spend an afternoon at Deezmaker Hackerspace in Pasadena, makers of the Bukobot 3-D printer. You will learn how to download and use all the relevant free open ...

Son: Dad, what's this thing?
Me: That's a 5 and 1/4 inch hard drive.
Son: Ok. Are you using it?
Me: Um... No ....
Son: Can I take it apart?
Me: ... YES!!!! Oh wait, I don't have the right screwdrivers. Here, take this thing apart. (See picture.)

Hahahaha... Dad, What's THAT thing?!?

BTW: Be careful of the strong rare-earth magnets inside the HDD.

Makena checking out a Makerbot Replicator. First time she's seen 3D printing. You can almost see the ideas churning in her head!

Moment of inspiration: heat lamps for the domestic kitchen. Or we can just turn off the TV and internet when breakfast is ready.

The best objective measure of how awake my brain is? Typing speed and accuracy.

I don't know, I can type even when I'm just about ready to pass out. Like right now.
