100% agree. I've loaded multi-gigabyte datasets into Postgres on my laptop and SQL is a great language for manipulating and aggregating data. Plus, when you use a database and SQL you can access that data from a wide range of applica

There are also no shortage of "Data Science" projects that are basically just showing off (e.g. somebody in a large org trying to get recognition for being advanced) or using an algorithm to justify a decision that somebody had al

Background: I currently lead a Data Science team at a big non-tech company. Previous to this I worked at a software company that had a Data Science team in their customer facing consulting group. I'm going to speak primarily about ap

I worked for an established software company (~3000 employees) that had unlimited vacation. How much vacation people really took varied greatly by managers and which part of the organization you were in. There were no minimums and no real p

What makes R code good for production is basically the same for what makes code in any language good for production. Use functions, local variables, tests, check for nulls, type issues, etc. I wouldn't say having loops is always a bad

Thanks to certain popular technologies like Hadoop, a lot of big companies have their legal teams looking at open source licenses as an alternatives to the big vendors like IBM. Using R and CRAN is getting easier because of this. A lot of

We used separate workflows depending on if the data was streaming or batch oriented (e.g. on-demand or triggered by a user). First I'll talk about batch oriented jobs. The company I worked for had a tomcat based product that exposed R

I used to work in the consulting arm of a software firm and we wrote and deployed R code in production at many Fortune 500 companies. We worked in almost every industry. I spent quite a bit of time refactoring bad R code so it could run re

This is what the docs say "When you select this feature, extensions are installed in the database engine to support execution of R scripts, and a new service is created, the SQL Server Trusted Launchpad, to manage communications betwee

That statement is overly vague and sounds like marketing BS. I worked on a project where we scored streaming data in R. The biggest bottleneck was getting the data into and out of the R session. We started out using disk based I/O an

I forgot this. If you are serious about staying with the company, move into or work with a group that is visible and known to the higher ups. Usually this happens when the manger is very good at managing upwards. In my last company many g

If could talk to myself pre-acquisition, this is what I’d say. First of all, think about where you want your life and career to go. Think about the skillset you have and what you need to develop your career and life. Think seriously about

The following is my experience with it. Feel free to skip over it. The short version is: Expect a tough time unless you are senior management. Unless you really like your job or are stuck, update your resume and start looking around. I r

This may seem like really basic and obvious advice, but I’ve always found it helpful to think about solving a much smaller problem, solving that, and then going to management with that as a guidepost for building out the larger project. Pu

Stats 101 is basically what you would learn in the first applied statistics course taken by an undergraduate (or advanced secondary schooling). Mean, Median, Standard Deviations, Z scores, T-tests, etc. For control charting, just look at

I work for a company that does a lot of Data Science Consulting. And I'm still surprised by how many companies I see that try to use complex methods to solve problems that can be solved by high school statistics and a little lateral t

Yes it is. Maybe I should have said "has many fanatics" instead of "full of" but they are absolutely as adamant and caustic as some religious fanatics. And on forums these people create the same kind of environment as

I doubt anybody from the industry tracked him down and made him go away. Headphone AMPs/DACs are typically made by smaller vendors or are low volume for big vendors. The major vendors are selling the "Beats by Dre" brand to

I used to be fairly active on a popular Headphone Forum, both before and after NwAvGuy appeared and disappeared on that forum. Nobody with a real engineering background and strong belief in the scientific process could actively participate

IME it is also important for management to officially recognize the need for a Wiki and provide some minimal resources and time to manage it. Otherwise it becomes just another thing for people to add to their ever growing list of things to
