How do I write a markov text generator?
I don't understand any of the articles on the topic.

>>55801846

I'm think how it works is you store all the possible first words and then for each word you store words that could follow it and each potential option has a probability based on how common it is. So the next word is picked randomly from the choices available and more common words are more likely to be picked so it might make sense.

Once the system works you feed in tons of data so that the probabilities are sort of right and you might get sentences that make some sense.

I wrote a thue interpreter and modified that to also look at transition probability (instead of being completely random).

Then I just fed it a rule set.

reading "The C++ programming language" feels like trying to cram K&R allover again, except 5 times that.

I always preferred going to cplusplus.com and just reading about individual key and sometimes not so key features. After doing that for a long time, I just skimmed through the Stroustrup book and didn't learn anything new.

Is there anything worse?

I need to geocode 200K physical addresses into lat/lng coordinates and my budget is 0.00 shekels. Google Maps API has a query limit of 2K requests per IP per day. In the past I was able to get a huge list of free proxy servers from the internet and feed it to my script that would basically rape the fuck out of Google servers with parallel proxified requests. Now, however, it seems like Google blocks 99.99999% of proxies. Wat do?

How do you abbreviate 'number'?

I often have variables that contain "number" but not sure how how to abbreviate. I've seen the following:

num_elements
number_elements
nmb_elements
no_elements
nb_elements

Indeed.

Obviously my HTML parsing needs some work, but I did this in like 20 minutes.

>>55803088
That actually introduced a race condition, so I scrapped it. The problem I have is bunch of goroutines waiting in something like

select {
case allocate <- img:
  // Finish up
case <-time.NewTimer(time.Minute).C:
  // Bail and clean up
}

Then I have clients that have to somehow find their goroutine before it times out, receive from it and do so without race conditions. Mulling this over.

Okay so I'm writing a recursive search function that iterates through a filesystem from a specified beginning path and examines .mp3 file ID3 tags. It then moves those files into specific folders it creates, named for the artist name found in the ID3 tag. I'm doing this in Python.

My original attempt iterated through the filepath using a for loop around os.path.listdir() and then os.path.isfile() and os.path.isdir() as conditional statements inside it, but I've just run across os.walk(). I see that os.walk() is a recursive search function that iterates through the file system and returns a list of all the files in it.

Can someone here with experience in Python please tell me that I didn't just spend a few hours replicating a core feature in the python os library? Because that's what it's looking like. Fuck.

I mean yeah I'm trying to do that right now. I've never written a recursive search function before and this is my first attempt. Can you explain why iterating through with a for loop is wrong? I feel like with nested directories it should be fine to go:

def search():
    for x in filepath:
        if x is file:
            do something
        elif x is dir:
            search(x)

that's not recursion my friend
that's a for-each loop

if you know math it's the difference between
factorial (n) = (big pi symbol) i for i = 1 to n
and
factorial (n) = n * factorial (n - 1)
factorial (1) = 1

He aims for an "academic style", which is why he uses a Roman font for code samples instead of something like courier.

Basically, you can only type according to rules specified by the editor.

You'd hit certain hotkeys to insert different syntax elements (for example, an if-statements, while loops, etc) wherever the cursor is.

Then you can navigate between the various sub-nodes of the inserted node, and either insert raw text (if that node allows it) or further sub-nodes for nested expressions/statements.

The cursor points only at a given ast node (e.g. the cursor could select an entire if-statement, or it could select one of the branches of the if-node, etc.), and only in certain positions could you type in raw text.


To save the file, output some language-specific ast format rather than the raw text

Another possibility would be something like a picked ast object for
python, which encodes literal instructions for the python vm to recreate the object

Hello, my name is Prateek. I like programming in Java. It is very fun and good job in my country. My family sent me to American university when I was younger. This was to my benefit and I now make $5 USD an hour with Java. It is very comfortable life, I suggested it to my friends and family. They plan to do it too!

Gcode is used to program CNC machine motion, for example:

G00 X100 Z50 Y50 //rapid motion
G01 X00 Z100 Y00 //linear interpolation
G18 G02 X100 Z00 R50 //clockwise arc on XZ plane

There are heaps of gcode parsers already out there but I want to add a syntax that lets me calculate coordinates on the fly so I'm going to have to bite the bullet and git gud.

>>55806498
Ah, that makes more sense. I've been using vim more and more for everything since I started using it for work, and I'm really enjoying it.

I'm sure many of these have equivalent plugins in Sublime (which is my second-most-used editor, hence the molokai vim theme), but you should check out undotree in particular. Combining it with persisent undo history (which achieves a similar goal to hot exit in Sublime), it has really made a positive impact on my productivity, working like a meta-VCS between commits.

Being able jump back to a version of a function from a few minutes ago, copy some text, jump back, then paste it (without worrying about overwriting my history) is great.

what do you mean?
do you want to calculate coordinates based on previous parts of the gcode program?

don't write a parser, write a simple code generator.

you can do that in any language.

So I'm learning python and one project is a random name picker now I have this

import random

name = ( "jay" , "luis" , "bob" , "sofi", "susan" )

print x 

But I'm wondering is there anyway to make it so the user enters the names via an input?

Yeah I'm also working on a kind of gcode generator that lets me draw a tool path on a 3d model of a material and execute the gcode, but I think using expressions as coordinates in the gcode would come in handy, for example:

(a = 150, b = 20)
G00 X(a / b) Y(a * b) Z(b + a)

So that it evaluates the expressions in parentheses to produce coordinates!

I agree that the vim defaults are terrible, both in terms of usability and style. Neovim is a bit better, but still not great.

That said, you probably have Package Control installed for Sublime, which is about as difficult as installing Plug for vim (ie, a single call to curl).

The difference is that the rest of the configuration is done via text files in a domain-specific language rather than GUI + JSON.

I think extending gcode with minimalistic syntax is more appropriate than having the end user write lisp code (although now that you mention lisp, I'm thinking prefix notation is the way to go!).

sqlite is fine when you need some persistent local storage and don't require fancy things like a separate server managing your database

It's better than dumping shit to a file.

>>55807295
you could have only one array, and each position of the array would represent a letter.
then you only need to call one time the print function

>>55807233

That's (((McCarthy)))'s fault.

>>55807435
Everybody liked s-exprs so nobody ever bothered implementing m-exprs.

>>55807435
Oy vey!
yes yes goy! hehe it's her fault!

>>55807422
I tried thinking of doing that, but the problem would be that, because each ASCII letter occupies several lines, it would print one letter, and then the next below it... Oh well..

>>55801574
So guys I'm going autism hypervision mode on Phoenix/elixir right now. Will there be jobs for it in the future?

For some reason I really like to get involved with the more obscure languages. Like I know I would be better off learning Go or Rails, but something about obscurity gets me rock hard

I'm writing a program that calculates the first 1,000 digits of pi iteratively.

I know there's a summation formula (pic related) that gives the nth digit of pi in hexadecimal, so all I would have to do is do a for-loop that does this 1,000 times. My main question would be how to do this math in hexadecimal. Would I have to create a 4-bit data type and work from there or could I use bitwise operations?

Is there an equivalent of Python's 'break' in C++?

>>55807593
Just calculate the number of decimal digits you need from the hex digit position and convert it?

>>55807505
Elixir isn't obscure.
Check out lamdaprolog

>>55807629
holy shit! thanks!

>>55807629
Okay, this is definitely a step in teh right direction for me, but I'm still a bit lost:

Let's say a string of digits is 'A35'
If it's after the decimal point, this would be:

(10/16^n) + (3/16^n+1) + (5/16^n+2), and this doesn't necessarily equal the number of digits (I did the above calculation, and it appears each fraction in hex is approx. equal to 3-4 digits in dec)

>>55807736
God that was so disjointed. Basically,
If it were .A35, which equals
.625 (1)
+.01171875 (2)
+00122070312 (3)

So I'm not sure what I can do (it looks like the leading digit is n-1 spaces away from the decimal, but I'm not sure how valid this is as you go on further)

>>55804533
>>55804640
That's a recursive depth-first traversal. You may use loops in going through each neighbor of one node at the same level, but it's still recursive as it proceeds through different levels of the tree.

Okay, I have a function that does the summation and so far, it seems to be working. It works until number 255, after which the result is NaN, presumably because it's smaller than the smallest fraction in a double.

>>55808286
Fuck... I'm too tired for this shit. Here's the code

        double sumVal = 0;
        for(int j = 0; j < 260; j++)
        {
            float tempInt =  j;
            sumVal = (1./pow(16, tempInt)) * ( 4./(8*tempInt + 1) - 2./(8*tempInt +4) - 1./(8*tempInt + 5) - 1./(8*tempInt +6) );
            double returnInt = pow(16, j) * sumVal;
            
            
            std::cout << "AT " << j << " sum equals " << returnInt << std::endl;
            
        }

>>55808071
That's embarrassingly parallel, if the problem is big arrays not being in a hot loop you could parallelize. Note that Python is terrible at concurrency and parallelization.

>>55808071
As for less lines:
c = sum((i in a for i in array)) - sum((i in b for i in array))

>>55808071
that code is logically incorrect if you are trying to count the #elements in a - #elements in b

>>55808297
why did you declair a tempint as a float and make it = to j?

Originally, it was to make sure 1/pow(16, j) would be a float, but after some reading, I realized I'm using an incorrect version of the formula.

The correct version is derived from the one I was using, but whatever... I'll work more on this tomorrow

JS doesn't have monads so the best I can do is pass input to functions without storing it as state. No state means no mutating data

Haskell is not pure but could be
Haskell restricts IO to IO computations for good reason
Obviously if you can side effect anywhere you can apparently write nicer code for this one instance

>>55811078
And monads are a pure expression of impurity, which is the point. In Haskell, if an unsafePerformIO function isn't used, you know anything performing side effects has a type IO x
