The Setting: Avoiding 4 Weeks of Runtime Recently, I was faced with a problem: I had written a rather complex simulation of a discrete time queueing network, and I needed to let this simulation run with some repetitions of the entire simulation, for some varying different parameter values, with many observations (i.e. ~ 2.000.000 observation). The goal was to verify that a new estimating procedure for such queueing networks provides sensible results.

Suddenly, Attention So, it seems like my blog is getting some attention. Recently, I was even featured on the front page of Hacker News: Number 17... only 16 more to go! Obviously, I am delighted and flattered by the number of people reading and discussing my blog. But since we're living in a material world, and I am a material guy, I kept on wondering "is there any way to monetize this in an ethical way?

As I recently pointed out, I have grown rather fond of Emacs and org-mode especially in recent months. On an entirely unrelated note, the FIFA world cup is right around the corner. Wouldn't it be nice to combine my passion for the greatest sport in the world (even including all the inevitable diving, arguing with the referees etc...) with my new-found passion for clear and concise org-agendas? Just so...

A couple of weeks ago, I started to work with Emacs, and I grow fonder of it every day. During a very short time period, it has become my go-to editor for nearly everything I do on my computer, including (but not limited to) planning my Todos (in org-mode, to be precise), setting up my agenda (org-mode again), taking memos during meetings writing my (longer) e-mails play around with new stuff write blog posts (this is the first of these.

I have a personal Google account, complete with gmail, gdrive and everything else. I first opened it up as a sort of spam email for all kinds of logins, but started to it use more and more due to its convenience. I was always slightly worried about the magnitude of data collected by Google on me, yet I never found a way to pinpoint exactly the extent of my slight worrying.

In a previous post I have shown you how to setup an AWS instance running the newest RStudio, R, Python, Julia and so forth, where the configuration of the instance can be freely chosen. However, there is quite a lot of possibilities of instance configurations out there: There are different instance classes (General Purpose, Compute Optimized, RAM Optimized, … ) and different instance sizes within these classes. For General Purpose, or t2, there are, e.

Hello world! My name is Sebastian Schweer, and I am a Data Scientist. This job description is increasingly popular, but it is notoriously difficult to describe precisely, what that entails. Let me show you one of my favourite definitions: Source. My job requires me to spend a lot of time each day writing code in varying languages, mostly R but also Python and SAS. This inevitably leads me to spend a lot of time thinking about both code as well as the process of programming itself.
