@evaristoc I've been out of the loop for awhile, what's the latest update in FCC growth, fitter room use? An interesting piece of data would be back and forth intersections in the chat room, or to put it another way, responses to help requests.
I've posted 3 questions in the help rooms and got zero replies other than @mutantspore saying hi. Wondering if it is because no one in the room recognizes me anymore, are there too many ppl asking for help or not enough experienced campers in the room? If I am having that experience are others? Is it decreasing FCC value and what can be done about it? That's a lot of questions i wouldn't know where to start

@AdventureBear your times of glory are gone! :)

People: For those who don't know @AdventureBear is a used-to-be well known participant :) (she is almost a FCC founder) and the author of few templates, like the Bootcamp Calculator or the d3.js bar chart viz.

@AdventureBear still, you question is important... we have been working on few things on that regard, but at the moment that part stays experimental. Not so easy as saying "one-two-three-Done!". :)

By the way: did you know about the FCC survey (Quincy)? Will you have some time to see if you can contribute with ideas and opinions, if not with a viz?

And how are your personal projects going?? The app for training performance measurement: is that already in the market or are you waiting for "the right moment"? :)

See that I am going for a jogging in few minutes and I don't have an app to measure my performance :(

@emilaasa @zcassini in the front end room. I was doing the back end/BASE jumps before many of the current front end projects were added so getti my front end certification is playing catch up! I had some questions about my portfolio site and will on you so as not to fill up this room off topic. Thanks for asking. @evaristoc I out a halt on all my back end projects while I went back to fill in gaps in front end, then life happened. In the past month my grandmother and my step brother both passed away and my parter had 2 serious injuries that were work related. And I've just been trying to take care of myself. Funny how I turn to coding for relaxation. Miss you guys!

Coding can be sort of relaxation when you know how to do it, and you are almost at that point!
Zac Cassini
@zcassini

@evaristoc Agreed. If things are going your way and you have the right music on it can be cathartic.

@AdventureBear same as @zcassini... I am still lucky that some people still remember me there too... I guess we are not many evaristo's in this program... That is easier to remember by difference that trying to remember who is mike....
That could be anyone!

Anyway @AdventureBear: there is also now a reddit channel that is gaining momentum, and it is not as crowd. Otherwise just use your influences: mutantspore is already a master in front end development for example...

Anyway: I am interested in your experience, hard to check in the Front-End room and the Back-End room...

Again, take it easy and see if we can help!

@evaristoc Just rembered I listened to a podcast the other day with Quincy about fcc. He talked a lil about you.
evaristoc
@evaristoc
May 02 2016 16:16

Really?? That is an honour! He didn't tell me that. Probably talking about the survey project...

I hope you will also have some time for that, @zcassini... even offering advice and small support here and there will come handy. Don't want to take the 100% of the time of anyone, but if we can all give a 5% of the time as a group, that could make a difference. Then Quincy will have to make a long list of people to talk about in the next podcast... :)

People: getting to go... @erictlaung I will check those files as soon as I am back

@AdventureBear again, the best!!

People:

For those interested in R as tool...

For the survey dataset @erictleung and me will be working on the dataset using R instead. R is @erictleung's choice as he has more expertise with that language. I can help him as I know R too. I also like R for some stuff...

However, @erictleung code introduced me for the first time to an already old R package, the dplyr library, one that improves the management of the R data frames:

@zcassini I have seen a few things about julia: VEEERY promising, competing really hard against python they say, but still new... Didn't realised it was erlang family!! I thought it was more like java...
@Evaderei thanks for that one!!

Can someone look at the dataset and quickly determine the following:
  • median age of respondant
  • mean number of months studied
Median debt
These should be pretty easy to calculate. My computer only has 8 gigs of ram and I don't even have Excel (just Open office) so I'm not able to quickly do so.
I need these figures for the article I'm writing that I hope to publish tomorrow morning.
evaristoc
@evaristoc
May 02 2016 22:03
@QuincyLarson:
The data is not cleaned yet, so this values are not totally correct, specially for months and debt:
  • median age: 27 yo
  • mean number of months studied: (gives a immense number: reporting median: 9 months)
@QuincyLarson:
The "debt" question: there is not one but several ones; people may have reported different loans or a combination of them.
I will quickly see what I can do before going to sleep, give me few minutes... The report will be PRELIMINARY. Again, data is still dirty.
Zac Cassini
@zcassini
May 02 2016 22:07
@evaristoc glad you chimed in cause I got 29.06089206 for the age

May 02 2016 22:19
You are maybe right...
I am using R but over the raw data...
for a quick check...

@zcassini wuak!

Zac Cassini
@zcassini
May 02 2016 22:25
actually got 30.91071429 for the average age. not sure how I got 29 the first time.
evaristoc
@evaristoc
May 02 2016 22:31

@zcassini Probably because 29 sounds more milennian? 30 is always a scary number... :)

@QuincyLarson Debts: I am getting numbers for student loans and mortgage... Strange -> no-one had a combined loan? I don't think so...
The average loan is:

  • mortgages: Median : 130,000; Mean : 189,384
  • students: Median : 20,000; Mean : 34,191

Data that was "incorrectly" reported by the user was automatically excluded of these analyses. We are trying to rescue as much values as possible.

Hope this helps! Take care!

@zcassini could you get the Median number of months, too?
@zcassini for age, Median might be more useful than average, as well

age needs some filtering as there are a few 120s and a handful of 0s and the real numbers seem to start at 10 and end at 75 with 1 80 and 1 86
