Had some fun tonight doing gradient descent linear regression from scratch in Kotlin, starting with a simple y = mx + b fitting. Once you get the multivariable calculus, it's stunning and beautiful how little code is required. https://gist.github.com/thomasnield/fbe2e2205233388577e6abe6f5bbe897

Got a suggestion to create a cheat sheet showing how to convert math symbols and expressions into Kotlin code. Here's the start, contributions welcome. https://github.com/thomasnield/kotlin_math_cheatsheet/blob/master/README.md

best would be if there was a svg that picks up foreground color and background or transparency based on css

Guys, sorry for off topic. Dear Admin, if this is wrong channel, please tell me where should I put it 🙂 I've been collecting Slack groups since 2016. In 2017, I set a goal to find 1000 groups and did it successfully. Now I would like to present the results of months of hard work in 2018. I collected and verified 2000 Slack groups - http://bit.ly/2000slack (link to Slack group directory). Please check this out! You can find there a lot of new groups related to Kotlin etc. Enjoy.

Short question as english is not my mother tongue: Let's say I have a

Recipe

class and a

RecipeDto

class. What's the plural?

val recipe : Recipe

val recipes : List<Recipe>

val recipeDto: RecipeDto

val recipeDtos : List<RecipeDto>

Like this?

Dtos

?

every gradle refresh now is triggering a bloody slow "resolving external annotations" process.. is it really necessary? May I turn it off?

gradle.. i wish speed was their n°1 priority, but nobody care about performance anymore nowadays..

Hello, someone who know threads and avoid undefined results on critical variables? For example if thread 1 have aquired a lock for "critical section X" and executes in the "critical section X". When the thread 1 executes in the "critical section X", thread 2 would also like to enter the "critical seciton X". Then, thread 2 tries to aquire that lock that belongs to the "critical section X", but the lock is already locked. What will happend to thread 2 then????? Will it spin in an extremely CPU-consuming loop until thread 1 unlock the lock? Or what is going to happend? Or what things would we like to happend with thread 2 in the meantime?

LaTeX? Can’t tell if serious or…

Also checklists don't really work on Youtrack. I don't have more info, sometimes it just doesn't work. I thought it was because I'm typing on MacOS and maybe line breaks are different, but I was not able to confirm this. But if the problem was line breaks, then why would it work sometimes?

Change the

fun

keyword to

funKT

for April fools :troll:
