FYI anyone interested in, or who has already submitted a talk or bought a ticket to, Build IT Right Conference in Newcastle. Due to unforeseen circumstances we had to move dates from November 2018 to 4th April 2019. https://bitrconf.org/

Morning

Morning!

Morning Everybody

morning

morrrrrrrning!

how's everybody doing?

any winter day it's not raining is a good day 🙂 🚲

On the tram today to make Lambda Lounge easier 🙂

It was... not pleasant. There was a very stinky dude right in front of me. I felt quite ill 🙂

I cycled, which I will regret if the weather turns 😕

o/

muggy 😑

moist. The worst of words

I also may regret not grabbing any type of hoodie or similar by the time I get home tonight. It's possibly not short-sleeved-shirt weather out there...

Morning.

Does anyone have an email address for @jr0cket? Please can you DM me if you do. Asking for a friend.

incidentally, a friend sent me an interesting talk over the weekend: https://www.youtube.com/watch?v=rnmcRTnTNC8

that looks good

One of the sticking stories in my memory was of a locked door, and those ceiling panels that most offices have. Elevated themselves and dropped in.

You can get a long way with a high vis vest and acting like you're supposed to be there

Someone nicked about 5 £10k projectors from Lancaster using that tactic

And the number of times I didn't get stopped or questioned when I probably should have been...

yup

This is mostly about actual physical intrusion

but I used to work at a personal-data-processing company which meant we had some great security trainings from companies actually doing varieties of pentesting; one of the things they stressed was the importance of not treating unknown people as “oh, new hire from sales”

Places that hire intensively can get really awkward on the “Excuse me, who are you?” “We’ve been introduced last week…” routine

after a thousand times of trying to figure out if I have met someone before, I think I have become numb to most of the embarrassment. One side benefit(?) of running so many events and doing public speaking.

I stop people every day that just start walking into our office as I walk out

"I'm sorry, who are you?"

people get angry - but if you've not got a keycard, and I don't know you....

I like to stop people I do know if they don't have their badge

there's about 150 people in digital so I know most by eye or by name

have watching the entire mr robot be a required point during onboarding -.-

👍

Morning 🙂

What is the most idiomatic way to test for something like every? (not (nil?)) coll?

@yogidevbear are you looking for some?

(every? some? coll)

Sounds about right

Thanks

I should be able to use this in conjunction with a let and if-let binding yes? So something like

(let [v (if-let (every? some?) coll
            do stuff with data here
            set a default)]

no

Feels a bit convoluted

how would that work

every? returns a boolean

you'd bind your local to either true or false, not to the coll

Sorry, typo

unless I misunderstood what you meant

Let me try this again

(let [v (if-let (every? some? coll)
            do stuff with data here to set v
            set a default for v)]
  continue with functionality based on let)

I still don't understand why you want to use if-let there, instead of just if

if-let works like (if-let [a cond] a default)

Fair point :face_palm:

Thanks for the sanity check @bronsa 👍

np :)

slightly surprising: (clojure.set/union #{} [:foo]) => [:foo]

clojure.set is famous for being one of the worse offenders of GIGO

i have a protocol which i extend to clojure.lang.IPersistentList in clojure - in cljs do i have to implement it on both cljs.core/EmptyList and cljs.core/List ?

yes

it is really annoying that cljs doesn't have a hierarchy of interfaces like clojure does

and I think it's symptomatic of a missing abstraction in clojure and clojurescript

is there some doc somewhere detailing which types i have to implement on in cljs for lists, vectors, sets, maps etc ?

clojure cheats by using the host-level interfaces but cljs is forced to extend all the available concrete classes

not that I'm aware of

yeah, my extend-protocol is butt ugly now 😞

ah well, worse things happen at sea

huh, looks like there are quite a lot of concrete classes to think about: https://github.com/zcaudate-me/brahmin/blob/master/src/brahmin/category/monoid.cljs#L10
