>>53575819
I'd say avoid go.
C would be good for teaching yourself pointers and getting a better idea of how things function at a lower level. I'd also recommend a functional language, maybe ML or Haskell, for a more principled and rigorous introduction to maps, filters, folds, and recursion, and the underlying theory behind them than Python can realistically provide. Scheme is a good choice for getting into metaprogramming. Clojure's concurrency model (channels) might also be useful.

Yes, I have made my own Lisp dialect. It is in fact a library to make your own lisp dialects. Sadly it doesn't use JIT or anything fancy like that yet.
I think lisp is a great choice because it is simple and gives you a huge amount of flexibility.
Anyone ever wrote their own scripting language?
I'm in statistics research, and I've built up my own small library of functions to deal with things I encounter on a daily basis, like parsing through different program's output files to grab specific results, fourier transforming things etc...
However, whenever I want to start a new project, I start a new c++ source and link in my library, and just plob in the functions I need in the right order. I was thinking of trying to make this process into my own scripting language so I don't even need to worry about compiling new code when I want to do something slightly different the data.

Moomin edition is best edition
I'm trying to write a theorem proving program in python that recursively tries rules against each other and adds new rules until it either runs out of combinations or finds a contradiction
I've hit a wall though, it just sticks the same two rules together every time until it hits recursion limit and crashes
how would dpt keep track of something like this?
I was thinking a 2d array of boolean values to keep track of what I have and haven't tried and updating that every time, but it seems like it would take up a lot of memory to possibly have a 20x20 array for each function call

mkFizz
– takes an Int, String and another Int, and
– returns a Writer, which accumulates its state in a tuple of type (Any, String) and returns Int as the result
There is no pattern matching in mkFizz, the where clause is just local binding, it's equivalent tolet divides = ...
in writer (n, ...)
There's a pattern match in final, tho:where (n, ...) = runWriter w
matches the return value of runWriter to the tuple

A linked list is a sequence of nodes. Each node contains an element of the list, and points to the next node in the list. The last node of the list points to null instead. The first node is the head of the list.
In contrast, an array list contains a single array, which contains all the elements of the list. This makes random access much faster than for a linked list. However, there are drawbacks: if appending an array to the list would go past the end of the array, a new, larger, array must be allocated and every element copied to it. This array is now used to hold the elements of the list. A new array must always be allocated to prepend an element to the list, and a copy performed. Thus prepending always takes linear time.
In contrast, prepending to a linked list simply requires creation of a new node, which is made to point to the current head of the list. This new node then becomes the head. However, appending to a linked list always requires you to traverse to the very end of the list, in order to set the pointer of the current last node to the new last node. Thus appending always takes linear time.

>>53576291
You'll need to keep a counter, and traverse the list, updating the counter each time until you get to the index you want, then insert the element as a new node pointing to the next node to be traversed and update the previous node.

I'm looking for a type of software that I'm not sure exists, but I'd like to write. Just wondering if you guys had heard of anything similar.
I want a workflow monitoring tool. The usecase is that I'm at a large organization and every team has their own processes that we have to manage and make sure functions as expected. Every server would have a heartbeat for statuses and hooks in specific processes to know that it was kicked off or that it has finished. Ideally it'd be decentralized so every node could have the same configs that propagate as nodes are added/removed. Ex: Let's say we have two pipelines, one for ops and one for devs
OPS: build server -> configure server -> start services
DEV: source control -> build -> deploy -> start services
The tool could handle both by checking that the executables are either running/completed/not started yet, whether that's bash/ruby/python/etc.
This is not meant to be cluster management or orchestration, just lightweight monitoring. Also I just want the senpais at Hashicorp to notice me.

>I agree. It makes different tradeoffs than Haskell though, and I don't think the payoff is worth the downsides of them.
I almost feel this way, but 9 times out of 10 I find myself working in OCaml over Haskell because it just feels so much more comfy to me. There are some features that I always miss when moving to Haskell. I do hate not having type classes, but I can live with that using modules. In Haskell, the lack of first-class modules is really annoying to me.
Also, I still haven't found what it is, but there's something that makes Haskell feel uncomfy to me compared to OCaml that really stops me from using it a lot of the time. I feel like a lot of other OCaml users have this problem too, because if you take a look at most of the big OCaml user's github profiles you'll notice that a lot of them have a handful of Haskell projects on there. I think it has to do with the libraries, honestly. Trying to learn an OCaml library is generally a whole lot easier for me... thinks like named arguments are great and it's often a lot harder for me to find good documentation for even some of the more popular Haskell libraries. For example, a few weeks ago I tried to start a project with Snap cause i heard a ton about it on Hackernews. It looked great, but looking through the documentation for it on Hackage it felt like I was getting an overview of how it's implemented rather than what everything does. Yesod documentation was a lot better, but it still feels weird that some random OCaml library with 10 users often has better documentation/example code than a popular Haskell framework. Anyone else have thoughts about this? Maybe I'm just picking a lot of shitty libraries, but I've had that experience with Haskell a lot and that really pushed me away from it.

You can store null still. It's an array of integers but it isn't "filled" until you put something in there. You can set slots to null when you're done with it too, but it still takes up place in memory. Not sure what you're trying to achieve.

Maybe you can make small programs and use bash scripting

>is it possible to choose what type of vector you want to create
Yes, it is. While the vector type needs to be known at compile time, it will be one type out of known types, so there is no reason why you cannot generate vectors of different types at runtime, e.g.
std::vector<int> generateIntVect();
std::vector<double> generateDoubleVect();
.
.
.
etc.
You can also make it more general by creating a base class that has some accessor code, and use inheritance to define collections for some of the other types you want.
You can also do something icky, like write a magic Value class that would allow for (seemingly) heterogeneous vectors, e.g.vector<MagicValue> test;
test.pushback(14);
test.pushback("A string");
test.pushback( some_other_object );
// the above can be done if the MagicValue class has appropriate conversion constructors and/or overloaded cast operators
// that is, in each case, the vector is taking an instance of MagicValue because the following is legal
MagicValue foo = 14;
MagicValue bar = "Test";
.
.
.
// etc
I don't recommend the last one, because it allows for some sloppiness when it comes to type safety. It also means you need to write your own way of querying the MagicValue to see what type it is, and you have to keep track of that carefully.

>>53575670
So I'm a senior CS student right now. I've done projects in Haskell before, but I still am sitting here wondering why anyone would use a functional programming language for a project when there are other options available. It lends itself well to small math applications I guess, but it seems more intuitive to program in something like C, and the readability of programs made with functional languages are shitty as best.
I really cannot wrap my head around the idea that people do things like write client/server applications in haskell. These people must hate themselves.

Can anybody recommend a decent online note taking service for programming? I tried and used Evernote for a while but it's complete utter shit for this.
I want to insert code snippets, preferably with syntax highlighting.
Some kind of easy formatting would be great too, like Markdown or BBcode, or some custom shit, I don't care.
It would be great if it would be available for Android too, but it's not a necessity. Online is enough.
Pls help

It is much, much easier to write a comprehensive test suite for Haskell code than C++/Java/C# code.
I understand your current view of things, though. My CS degree taught me virtually nothing about writing software in the real world.
These days, immutability and purity are a godsend to me.

using Haskell and OCaml often lets you write code about the length of Python (or shorter!) but statically typed, for one thing. it's also a matter of functional programming being more fun for me. I find it a lot easier to express my ideas in terms of functional code and it makes it a lot easier to refactor for me in the long run, so it's much less stressful/boring than writing imperative code.
fuck yeah i'm good af

It's so easy to solve and replicate this all you have to do is implement the Lexiburg algorithm and then based off the captcha data reverse engineer it using calculus equations and finally redirect output from the servers internal information

You're passing a string, not a char. You want:vector< vector<char> > board(3, vector<char>(3, '*'));

>>53575640
wrote a VM (and an assembler) to learn about computer architectures and shit
made it write the registers to stdout every time it executes an instruction
I think it kind of works
there are 17 instructions, divided into operations (which take registers for two operands and another for the result), jumps (which take two registers, and if their comparison is true, jumps to the location in the third argument - seems to be a bit broken) and memory / register shuffling ones, which are all pretty arbitrary

I've never understood, how do you go up to previous lines if you made a mistake and need to correct it?
Do you rewrite the entire program every time you realize you've made a mistake?
Is there some sort of command to do it? If so, I assume it uses line numbers, doesn't having to type out line numbers every time you want to edit a line get tiring?

Yes, you can run a Haskell shell called by the command ghci.
Using Java to make a program which calculates the area of shapes but having some trouble at the moment.
First I had input/output for diameter, length, width, base, height, areaC, areaR, areaT all in the main and then three separate methods for calculating the area (of the three shapes) and returning the values.
Then I split the main into three separate methods, all the circleStuff, rectangleStuff and triangleStuff (handles input and output for relevant shape), which worked fine.
But now I want to split the input and output up (so I have separate methods for each of them): inputInteger, inputReal, outputAll. However, when I do this it fucks everything up because the output depends on variables initialized in the input.
Is there anyway I can pass variables between methods so I can use the values I get for the diameter, length, areaC, areaR, etc? Or how do I just make a method which outputs, "The area of the SHAPE (with DIMENSION = X) is AREAm^2, AREAcm^2, AREAmm^2." ?
