Re: Wine and WineBottler?

I've used it for quite a bit in the past but not used it for a few years now. Usually it's better to use VMWare for most things with a full Windows but Wine is a good option for some things where it works.

Quite a bit of info on http://portingteam.com/index although game focused.

Re: Pressed to sign contract quickly

Take the amount of time you find reasonable which is most likely less than the deadline. My team was on the other side recently and were being pushed to hire someone quickly because of the additional workload being brought on and there were constant pushes from the higher ups to get the person on-bo...

Re: Python 2 or 3 more common in finance?

The hold over generally is because you have something that works but you have no track of the requirements and there are no good unit tests or integration tests so upgrading or moving on is scary. This happens all over the place in any language and/or framework.

Re: Python 2 or 3 more common in finance?

 Moving to new versions is never easy. There are still critical applications running under MS C++ 6.0! Especially where there is combined hardware-software is involved. I don't see an upgrade to C++11 soon. I'd argue that it depends on the language, software and development process. If your require...

Re: Programming in R (on Mac)

Yes, we used to use custom stuff but opted for https://github.com/hadley/testthat in the end.

We have an internal Github Enterprise instance for version control.

Re: Programming in R (on Mac)

Note you can also call R from Python directly where Python doesn't have the modules to meet your needs so it's a natural flow to use Python as a primary but if the focus is on statistics rather than building out a full application or framework starting with R only has little downside.

R has it's place, Python has it's place. Your post reads like this: "HEY DON'T DO IT ANY OTHER WAY THAN ME, I MUST VALIDATE MY OWN OPINIONS AND CHOICES BY MAKING SURE NO ONE DOES ANYTHING DIFFERENTLY".
