Some would go to fight with a Long Sword, others would prefer a Katana. I think that's fine. Master what works best for the way your mind and body works. That said, I'd hate for languages to adopt a lowest common denominator just

Honestly, that describes exactly my programming workflow when working in Clojure. The whole process happens in Clojure. This language is small enough to write on a single piece of paper Check, Clojure is one of the most concise language o

Not all REPLs, just like you had to preface debugger with good, you need to preface REPL with good. You really need to give a good REPL a fair try to know what I mean. Most people also thought tests wouldn't add much worth, and took a

I've used Haskell, have I overlooked parts of it? How does it solve my problem? Also lazyness I'm not a super fan of. And I/O is kind of a pain, not sure its worth the overhead just to achieve purity. P.S.: I encourage people

Not really, I often don't need them. They're mostly for being able to reset the full app state back to how it is at startup. You can also just restart the REPL, though some people find waiting 5 second for that too annoying. I wis

More like cement. I don't mean to be dismissive, but REPLs aren't created equal. I've used good IDEs with Python and Java and C#. The C# debugger is probably the best, but its really not the same thing. Python could probably

But what I don't understand is if you can actually develop real programs like that? Well yes, I do it daily at my work. We develop backend SOA enterprise services like that, it works great. Surely even in Clojure code there are lots

Well, yea, hopefully in the future we have languages that allow both. I do feel like research in language design has ignored the interactive and fast feedback loop aspect though, at least from the reasearch I know of. My biggest gripe with
3429.
by didibus 9y ago
It's true, but it's more a treatment then addressing the root cause. Rich Hickey, creator of Clojure has a fun quote that goes something like: "You thought you wanted TDD, but really you wanted an interactive REPL." My g

Ya, I think that's just the familiarity hump. Most people don't get over it, and the few that did geek out too much about the possibility of infinite macros, and how you could extend Lisp, while eventually realising how few made i
3431.
by didibus 9y ago
Agree whole heartedly! That's why my favorite language is Clojure. That interactivity, instant feedback, seeing the program running as you are tweeking it, its a bliss to use and it creates better more functional software. Imagine play

Is it logical to code in Racket vs just coding in Chez Scheme? How much does racket bring to the table on top?
3433.
by didibus 9y ago
It's probably not what you want to hear, but there's a "I get it" moment I reached at one point, where my intuition just all of a sudden was able to quickly pin point all my errors. There's a lot of these moments in

You'd use an interface for polymorphism, much better. That said, I have to thank you for your suggestion of doing sum types with inheritance. I hadn't thought of it, and the use case presented itself at work yesterday. So I learne
3435.
by didibus 9y ago
Okay, but its not, not from the perspective the best practice comes from. The most common use cases for object inheritance can be delivered with object composition instead. This is much more like loop vs recursion.

Or learn some self control and restraint.
3437.
by didibus 9y ago
"but that's a misunderstanding of what inheritance is used for" I'm not sure what you imply. Most OOP languages where people tell you not to use inheritance, but composition instead, so java, c++, c#, etc. In those langu
3438.
by didibus 9y ago
No, sum types and product types relate to values, inheritance and composition relate to objects, which include values AND behavior. Inheritance is therefore abused to share behavior. This distinction is important, and relates to some common

Can someone more knowledgeable then me shed some light on a few issues I have? 1) Isn't it the case that the free speech amendment protects censorship only from the government, and not from anyone else, including private or public comp

Can someone explain to me Java EE?

How's LFE in comparison? I don't hear as much about it, but I suspect (don't know why), that its closer to Erlang, any comparison with Elixir?
3442.
by didibus 9y ago
These all exist, you just don't agree with them being reasonable: Scala, Common Lisp, C++, D, Clojure, F#, OCaml, Kotlin, etc. Those could all count or not depending on your subjective opinion. The truth is, it is difficult to create t

I always felt like patents shouldn't exist for ideas, but only for implementations. Having the idea, while sometime novel, is always easier then coming up with the implementation of it.

by didibus 9y ago
Hum, thanks for the info. I feel curious to try it out. I think names should be namespaced though, that could solve the issue of having a length or value named property. The namespace could distinguish between two values that aren't co
3445.
by didibus 9y ago
I see, sounds interesting. Are the names namespaced? And how would a method know its compatible? Do you type the properties a method needs instead of the object name?
3446.

Make sense, you might be seeing a real trend, but maybe not. You can evaluate things from personal experience, and even a small amount of negative individual experience can hurt a business, because of word of mouth. You should also calibrat

Is structure defined just by type? Like is all things which only have two integer properties considered the same? { Int age; Int weight; } Would be equal to: { Int x; Int y; } ?
3448.

Personal experience is anecdotal by definition. What are the other problems? Anyways, I'm not defending, just surprised the HN crowd accepts a few anecdotes which are statistically insignificant given the Amazon volumes. I see question
3449.
by didibus 9y ago
You're being persuaded by anecdotal evidence. At the volume of sales Amazon makes, fraud is but a tiny fraction. The probability of your next purchase to be a fraudulent one is minuscule. Not saying fraud isn't an issue, and there

I'm not convinced by this. Respectful discourse is good, but I'm not sure disrespectful discourse is. I feel sometime that does more harm, because it sends an underlying message, that our moral values allow us to be hateful to oth
