The cover is a nice tribute to Hal.

@zcassini lol

The examples in this book were written for and tested with R Version 2.15.3

Pretty old though. First published 2013, but was written may be much earlier

@jacobbogers "advanced R" is a great book, and here is the companion site where it is free http://adv-r.had.co.nz/

hi @/all,, how to get the API key for FCC API?
evaristoc
@evaristoc
May 18 2016 07:17

Welcome everyone.

Taking a look at Advanced R too, @zcassini. I think they are letting out mostly books that are relatively outdated, but even if the versions have been replaced by better ones most of the techniques are still up to date.

@gayathry2612 I did some kaggling before coming to FCC. Really good. If you want to go ML, that is one of the best places indeed. Go to previous challenges and read the fora when public, and even try to solve previous problems even if closed if you have time.


People:

Hi New Comers,

We are currently working on data coming from the first FCC Survey (15,000 records, 40 questions). Join us! @SamAI-Software is very active in that area and he is organising the info. You can see @SamAI-Software's analyses if you scroll up this page. We are discussing the results and giving tips for our visualizations. Historically we have been using python for the analyses in this room, but for the FCC Survey we are using R (@erictleung's code).

The objective of this exercise is to bring those results as d3.js visualizations. You can see @krisgesling's map for an example. If you don't know d3.js yet, you could at least make some analyses on the data that could be make as viz later on.

The room is open to all the topics and discussions even though the focus data is usually FCC data.

I have also prepared a (WIP) page of what has happened in this room since its foundation if you are curious:
http://evaristoc.github.io/FreeCodeCamp_DSR/

Hope you will all enjoy!

/all A huge round of :clap: for @erictleung for merging and cleaning the dataset, and everyone else who helped with this process.

The full, cleaned dataset is now available here: https://github.com/FreeCodeCamp/2016-new-coder-survey/tree/master/clean-data
Please use this for building your visualizations.

To my knowledge, there's nothing else that we're waiting on, so let's get started answering these questions with D3 data visualizations :shipit: https://github.com/FreeCodeCamp/2016-new-coder-survey/issues?q=is%3Aissue+is%3Aopen+label%3Aquestion

Good luck, and if you have any questions, this chatroom is the best place to ask :)

@ddrdushy although the FCC API is ready, FCC has decided to hold on its use while revising again if complies with campers' privacy T&C.

@evaristoc interesting! I am new here, but I will contribute any way I can. This is right up my alley.
I just looked over the questions, and some results. Is the survey questions to be expanded in the future?
evaristoc
@evaristoc
May 18 2016 10:21

@gitdek Great! There are no plans for a expansion in the short term. There is a proposal for an annual survey, 2016 is the first one.

Have a look! There is some interesting stuff in that dataset... Check the repo and also ask @SamAI-Software.

so the survey was filled out by members of FCC only, so theoretically you could include metrics(and keep them anonymous) ?
that might give some interesting insight into analytical data pertaining to certifications
evaristoc
@evaristoc
May 18 2016 11:46

@gitdek the records are anonymous already.

Not only FCC members I am afraid, but you can analyse data for the first 2 weeks to get the best of FCC members, who were the main surveyed during the first stages of the project. Maybe... although I would recommend not to try that extrapolation and just concentrate on survey results.

@gitdek by the way, are you interesting in creating D3 visualizations?
J Puglisi
@gitdek
May 18 2016 14:08
I can't commit much of my free time, but I will take some of my other projects using R+D3 and generate some visualizations with the datasets
I do quantitative finance all day in R (work), so I'll go through my libraries and see what will be useful.

About how many months have you been programming for?

  • Software developers with less than 1 year of experience tend to spend much more time studying programming rather than their experienced colleagues, while for respondents without software developer's job it's the opposite - with more experience they tend to spend more hours per week studying.

I feel like last statement might be too complicated and can have some English mistakes.
Please, feel free to correct me! :)

In a different direction, not because of politics but just check the VIZ for this one, as example and possible inspiration for your your projects?

I spend half a day to do the design, I think you will like it, I like to pimp things up and learn new CSS things
I think a real designer would do it in 5 min, lol
