Bore da

bonjour

Morn!

morn

I’m really enjoy this summer

been so lovely the last couple of days

morning

we had some heavy downpours last night and it has cooled down a lot now...

I'm still wearing shorts

yeah still shorts weather for sure

it would be cool if we could create an app/thing that would let us take the temperatures around us in our respective offices, then show them on a map.

Just a silly idea i thought of but it would be fun to do i reckon

You could literally create a heatmap of the uk 😄

https://www.forecast.co.uk/temperature/ like this but less blocked off?

I'm surprised something better doesn't already exist. I guess it's more of a toy than practical? Not gonna change as you go across the country really.

Yeah could be, maybe its a dumb idea. But having a more granular look at offices around the

yeah exactly

Do you mean temperature in the office or around the office?

morning

If it's around the office there's https://www.wunderground.com/ where you can send your data.

@kevin42 can you query their data though, for your own analysis?

https://www.wunderground.com/maps/eu/uk/Temperature.html nevermind, they're on it

@guy nice idea. Texas Instruments do a nice little IOT device with a load of sensors and that sends the data direct to IBM Bluemix platform, all the visuals are done for you. Not sure if you can mix others information coming in though.

mmm interesting, i was thinking just raspberry pi style

but that sounds cool

as far as I remember (this was 4-5 years ago) I think they have an api. The problem a long time ago is that it was missing data point in the UK and we wanted data in the world too.

@guy I’ve done Pi/Ard stuff in the past with a DHT-22 temp/humidity sensor.

how was it?

was it hard to do?

Not overly hard, Alasdair Allen did some good write ups on the Ardruino. Just gotta be careful with the 3v line. Readings were easy, it’s just case of where/how you’re going to send the data.

Was done in Python on the Pi though and I never used the DHT there I’m afraid.

no worries thanks for the information!

pleasur

@rickmoynihan always good to see the open data crowd. 🙂

Morning all

🙂

Needs to work, but wants to Clojure. What a conundrum!

are you london based @yogidevbear ?

Nope, I live in Horsham (West Sussex)

About a 55min train journey from London Victoria

ah ok, our office is next to Mansion House tube station

extra 15 mins from Victoria station on circle/district

Do you live in London too?

brixton, which is about a 40 min door to door for me (though I have a 10/15 min walk to the station on brixton end)

That's nice in the summer months

aye lots of new stuff in the last few years

Context switching between Python and Clojure is not as hard as I expected it to be...

Hello everyone 🙂

python is just common lisp with poor syntax 😉

(1 + 1)

@dominicm not enough tabs

last year I accidentally wrote (func arg1 arg2) in pycharm and it didn't complain about the syntax.... so it confused me for quite a while.

you can write all of python inside tuples if you want

but don't

http://norvig.com/lispy2.html follow this, and then just write lisp again

life is better this way

@dominicm - I will have a look at that...

Thx!

disclaimer, never done this! 😛

@dominicm - Looks fascinating, but it's not for now__...

😉

pixi is cool, it's a shame it can't interop python

Yes, I thought the same thing when I looked at it, 'cos it is VERY cool.

But when I want to write Lisp I use Clojure and that can interop with Java, so I am going to assume it can interop with Jython as well..?

I'm having a really weird issue with a csv, I can pull all the values out using get-in, apart from the date which is a date string, even if I copy a row out from the repl into the editor and def it, it still return nil. I tried not using keywords, and even renamed the field, but it still won't play ball

this is the def

that quote looks suspect

probably unrelated, but i’m just surprised to see it there

there’s no date in that example though

I know, I changed it to bob

sorry, it was one of the straws I was grasping at 🙂

@geek-draven that def works for me on http://tryclj.com

weird, it's not in my editor, even 'find' is returning nil. Thanks. I'll try running it in lein rather than proto repl and see if that makes a difference

nope, lein is returning nil too

@geek-draven try (keys test-data) and (vals test-data).

@dominicm this is what I get for (keys test-data)

"bob" is in there. How about vals? 🙂 Do you see the 06-…?

also getting nil in http://tryclj.com too

@geek-draven how are you getting the key out?

no, just the value

sorry

(get-in test-data ["bob"])

I did (get test-data "bob") which worked. Didn't try get-in. Though wouldn't expect differing behaviour.

still get nil with that in tryclj

> (get test-data "bob")
"06-05-2017"
> (get-in test-data ["bob"])
nil
> (get test-data "bob")
nil

have I broken Clojure 😞

> (keys test-data)
java.lang.IllegalArgumentException: Don't know how to create ISeq from: clojure.lang.Var$Unbound

Give me some Clojure:
> (def test-data
    '{"store_name" "Leather Lane", 
        "net_sales" "2231.87", 
        "gross_sales" "2782.90", 
        "check_count" "321",
        "bob" "06-05-2017", 
        "promos" "36.50", 
        "comps" "88.65", 
        "tax" "0.00", 
        "guest_count" "328.00", 
        "payment" "2657.75"})
#'sandbox18953/test-data
> test-data
{"promos" "36.50", "comps" "88.65", "payment" "2657.75", "guest_count" "328.00", "store_name" "Leather Lane", "net_sales" "2231.87", "tax" "0.00", "gross_sales" "2782.90", "bob" "06-05-2017", "check_count" "321"}
> (keys test-data)
java.lang.IllegalArgumentException: Don't know how to create ISeq from: clojure.lang.Var$Unbound

I removed the quote from my def after @glenjamin mentioned it

the quote should make 0 differnece here 🙂

yep, I'm getting the error now

don't trust the sandbox any more

right, works fine in my local repl (not tryclj)

wondering if we were sharing a namespace

If you do (def x) what is the var name?

Mine is 18953

Mine is 19031

okay, cool 🙂

I can values and keys from my local repl, but the get and get-in are both returning nil

Must persist across refreshes using a cookie or something

anyway, this is fucking weird

I've spent the week parsing emails, pdfs and xlsx files, so thought a csv would be an easy Friday afternoon task 😄

get works on some keys but not others?

yep

eugh, I guess /clj doesn’t play well with smart quotes

anyway, i was wondering if it’s an issue with extra invisible chars

but you said you renamed the key, so maybe not

what about (get m (-> m keys (nth 4))) or whichever key

Thank you, that works!

that suggests weird characters in the string to me

yes, might ignore the header row and write my own

clojure's = on strings does what?

"foo".equals("bar") it seems

looks like it is weird characters, if I copy the key from the def and manually type 'bob' I get false

Thanks for both your help
