F# Not just for finance

While I think F# is a great programming language. The article missed some good uses of it.<p>Specifically the article missed one of largest F# deployment, in production, in the world at this point. We use F# at Jet.com and it powers every part of our core business from our dynamic pricing algorithm to search and analytics.<p>Over 4 million customers already on jet and over 2200 cores on azure all running F# code.

There is an interesting article about rewriting C# project in F#, with impressive results: <a href="http:&#x2F;&#x2F;simontylercousins.net&#x2F;does-the-language-you-use-make-a-difference-revisited&#x2F;" rel="nofollow">http:&#x2F;&#x2F;simontylercousins.net&#x2F;does-the-language-you-use-make-...</a>

I was an early adopter of F# (1.0) and promoted it pretty heavily in my previous job. We used it for some of our prediction code.<p>I&#x27;ve since left and move to the Linux world, but have become more involved with using OCaml. Both are great languages (probably my favorites) and that&#x27;s after investigating Haskell for a while. F#&#x2F;OCaml&#x27;s ability to easily move between functional&#x2F;procedural&#x2F;OO worlds makes it super flexible.

I liked tinkering with F# on VS Code with Ionide (<a href="https:&#x2F;&#x2F;marketplace.visualstudio.com&#x2F;items?itemName=Ionide.Ionide-fsharp" rel="nofollow">https:&#x2F;&#x2F;marketplace.visualstudio.com&#x2F;items?itemName=Ionide.I...</a>), but would love to hear from folk doing F#&#x2F;OCaml as to their toolsets.

Is anyone using F# on Linux? How&#x27;s the experience?

Here is the Louvre Architect demonstrating the use of F# to help with the design of the structure: <a href="https:&#x2F;&#x2F;channel9.msdn.com&#x2F;Events&#x2F;FSharp-Events&#x2F;fsharpConf-2016&#x2F;The-3D-Geometry-of-Louvre-Abu-Dhabi" rel="nofollow">https:&#x2F;&#x2F;channel9.msdn.com&#x2F;Events&#x2F;FSharp-Events&#x2F;fsharpConf-20...</a>

Just tried F# on <a href="https:&#x2F;&#x2F;www.codingame.com&#x2F;games&#x2F;puzzles" rel="nofollow">https:&#x2F;&#x2F;www.codingame.com&#x2F;games&#x2F;puzzles</a> Don&#x27;t really see the use case for me, but fun to try smthg new =&gt; &quot;one new language a day keeps the boredom away&quot;

I came across F# a couple of months ago. Very nice language! Short, expressive, no noise like declaring vars&#x2F;types that can be easily inferred at compile time. |&gt; is amazing. Tuples. &#x27;match with&#x27;. Took a couple of weeks to get over the hump, but I never looked back since. Work related stuff is still C#, but tooling, prototyping etc I do in F# now. Highly recommend. Also made me to rediscover glorious past of OCaml&#x2F;ML that went over my head at the time (like most things).

I enjoyed reading this retrospective about someone converting 30,000 lines of Python to OCaml.<p><a href="http:&#x2F;&#x2F;roscidus.com&#x2F;blog&#x2F;blog&#x2F;2014&#x2F;06&#x2F;06&#x2F;python-to-ocaml-retrospective&#x2F;" rel="nofollow">http:&#x2F;&#x2F;roscidus.com&#x2F;blog&#x2F;blog&#x2F;2014&#x2F;06&#x2F;06&#x2F;python-to-ocaml-ret...</a><p>OCaml and F# are quite close.

I&#x27;m quite sure KDB pays more.

I want to suggest looking at a language like Erlang&#x2F;Elixir that didn&#x27;t start out from corporate self-interest (i.e., was open-source from the get-go) but a rising functional tide floats all boats. (And besides, Elixir &quot;borrowed&quot; a few good ideas from F#.)<p>I&#x27;ve had nothing but good experiences during my forays into functional langs. Here&#x27;s to a more functional, immutable, easily-concurrent, easily-unit-tested future

Is porting OCaml code to F# on Unix straight forward? Is there something similar to the Opam package manager in F#? Thanks for your thoughts.

Where is R on those charts on functional languages?

Where are the best place to find that F# jobs? I will love to work on it (+17 developing but this years I have picked F#)

This was a bit of a surprise to me. Is there a disproportionate amount of people in Finance using F# compared to other technologies? Any particular reason for that if the answer is yes?

A high price tag for a niche language (purely defined by &quot;popularity&quot;) is hardly surprising, simple question of supply and demand.

I think the article is spammy and has a clickbait title. Unfortunately reading and addressing the actual article on Hacker News is old-fashioned.<p>StackOverflow surveys, while interesting, are probably meaningless because they suffer from selection bias. Even so, I would guess that F# developers are very well paid, like other developers of FP languages, but it&#x27;s probably not because they work with F#. The causality is likely reversed - good developers that tend to be well paid are also the kind of people naturally interested in expanding their skill set, hence interested in FP languages.<p>Nothing screams spam more than usage of a hot keyword like &quot;<i>functional programming</i>&quot; while leaving hints that you don&#x27;t understand what you&#x27;re talking about. I would expect an article that reads like a marketing brochure to at least make a short attempt at explaining what functional programming is. If you copy&#x2F;paste testimonials from fsharp.org&#x2F;testimonials, you could also copy&#x2F;paste from Wikipedia. But then, their own course named &quot;Functional Programming&quot; doesn&#x27;t seem to have anything to do with actual functional programming: <a href="https:&#x2F;&#x2F;fsharp.tv&#x2F;courses&#x2F;functional-programming&#x2F;" rel="nofollow">https:&#x2F;&#x2F;fsharp.tv&#x2F;courses&#x2F;functional-programming&#x2F;</a>

any good tutorials for F#?

Long time no see, #F.

&gt; F# came out as the single most highly paid tech worldwide and is amongst the third top paying techs in the US<p>Wouldn&#x27;t the latter be implied by the former? Or am I missing something?

Programming languages are hyped now worse than cars : &quot;From code to colossal: Waagner-Biro recently used F# to construct the dome of the Louvre Abu Dhabi museum&quot; They used X programming language to build the dome of a museum ? Wowwww...<p>It&#x27;s sad.
