"While I love the power of Lisp, I am not a devotee of functional programming. I see nothing bad about side effects and I do not make efforts to avoid them unless there is a practical reason. There is code that is natural to write in a functional way, and code that are more natural with side effects, and I do not crusade about the question." -Richard Stallman

I have a question regarding console applications. I want to make a program, which upon first login asks to create an admin account. Then, that admin account can create new accounts and save data in a txt file. All encrypted of course.
Now, I have a problem; how do I change between accounts without using some sort of database? All account information will be in a single txt file, each in it's separate line. How do I switch between them? All of them will have ID's, with the admins being 0.

first to show off my pro code Ive been a python major for 7 years now
I made a cool ass digital clock

import time,datetime

a0 = ["00000"," 11  "," 222 "," 333 ","4   4","55555","  666","77777"," 888 "," 999 "]
a1 = ["0   0","1 1  ","2   2","3   3","4   4","5    "," 6   ","7   7","8   8","9   9"]
a2 = ["0   0","  1  ","    2","   3 ","44444","55555","6666 ","   7 "," 888 "," 9999"]
a3 = ["0   0","  1  ","  2  ","3   3","    4","    5","6   6","  7  ","8   8","   9 "]
a4 = ["00000","11111","22222"," 333 ","    4","55555"," 666 "," 7   "," 888 ","999  "]

def numap(w,x,y,z,f):
    print(a0[w] + "  " + a0[x] + f + a0[y] + "  " + a0[z])
    print(a1[w] + "  " + a1[x] + f + a1[y] + "  " + a1[z])

    print(a4[w] + "  " + a4[x] + f + a4[y] + "  " + a4[z])

while True:

>>>59266196
BTW you can repurpose your solver as a random state scrambler. Most fags scramble with random moves but random moves does not guarantee a random scramble. Random moves make easier scramble show up more often. It's not as a big deal when working with 8 puzzles but when doing 15 puzzles it's noticeable and pain obvious on higher order ones.
For scrambling:
>generate random state
>check parity to see if it's possible to solve
>if impossible go to step 1
>else solve it
>print out the inverse of the solution as the scramble

Hey guys I'm just learning C now and what's everyone's obsession with pointers? I understand what they do, but why do people use them all the time? Why use pointers for adding 2 numbers?

What would give a person brain cancer if he went from python to lisp?

>>59266444
>but why do people use them all the time?
Pointers are absolutely vital in C. It would be very difficult to write a non-trivial program without using them.
>Why use pointers for adding 2 numbers?
That is a typical situation where you would use a pointer.

You WOULDN'T use a pointer for that.

>>59266489
Use existing engine (irrilich, ogre3d, openscenegraph, urho3d, gameplay3d) and program with c++.
Or use you choice of language, pretty much all of them have wrapper for sdl and opengl.

hello python noob back again

>>> for i in listb:
...     lista.remove(i)

What can I do to stop it erroring out if listb contains something not in lista? Like a catch or an if contains or something like that

ex lista=[1,2,3] listb=[5,6,7] would make the above code crash and I just want it to do nothing and be like okay we tried to remove it and it wasn't there and that's okay

Is SICP still relevant?

>>59266498
Understandable, not everyone can handle the freedom of dynamic typing, and need to have the compiler hold their hands. That's why in Lisp, you can have this (quoting an example from the Hyperspec):

 (defun equidimensional (a)
   (or (< (array-rank a) 2)
       (apply #'= (array-dimensions a))))

 (deftype square-matrix (&optional type size)
   `(and (array ,type (,size ,size))
         (satisfies equidimensional)))

You can then use FTYPE and TYPE to declare your types in a DECLARE form. Need monads? There are macros for that. Currying isn't given by default, but that is a pretty simple function. Purity isn't too much of an issue, and the Hyperspec documents cases where side-effects occur anyway.

>Currying isn't given by default
of course, since lisp is trash. it can't even have auto-currying for every single function. is it even Turing complete?

>>59266719
I'm sorry, but you must be confused, redditor.
Never ever recommend usage of objects or OOP here.

Can I get some resources for C++ please.

I need to know when to use .h and when not to.

>>59266750
see >>59266740

>>59266730
Of course it is, anon. Not to mention, static type checking can be given by Lisp. But that's not really meaningful, as the compiler is available at any time.

Basically if you're not writing self-modifying Assembly, you should flip burgers instead.

Quick question about linq. Can you use it to read specific text from a file? For example, in a file somewhere is written "cuck: value". I want to search for "cuck" and compare the value to user input.

Currying by default I assume would involve extending the evaluator through a combination of *evalhook* and *applyhook*. I've never tried this before, but I'm interested now.

Still working on my userspace sysfs NVMe driver. Made a couple of functions for submitting NVM commands and polling for their completion (but more logic is needed for phase bit etc). I'm also extracting some data about the controller from the identify controller structure.

The next step is to identify namespaces. After that I will try to create (and delete) IO queues and host them on GPU memory.

Mood

Really? This is ridiculous. 3d graphics is super easy now that you have so many resources to throw around. You can actually just draw stuff with your shaders and it happens in reasonable time on user machines.

And most libraries that people use for graphics only do basic stuff like set up VBOs, load textures and meshes.

>>59267492
Don't see how that's particularly relevant to my post but yeah to some extent. I wouldn't consider it gpu programming if you use some high level graphics library to draw a few meshes on screen. The abstraction usually tries to do away with the base graphics api entirely.

Words like low level and high level are problematic to use because people don't agree on what they mean enough to make them useful. When you say C is low level it's only really low level in terms of programming languages in general. But it's not all that low level when you consider the extra concerns you've added.

I'd say cuda is very high level though. But I haven't used it extensively, just a little bit.

>>59267607
Last modified date is pretty good. If you're comparing images without such information and you only need to know if they're different you should realise that there's no way of telling without comparing the entire image. You can easily early out but if you're to determine if they're exact copies you have to compare every pixel. A hashing function by its nature won't help you because it's a lossy translation of data. Multiple combinations of pixels correspond to single hashes.

Complete the load function that takes a list of strings as an argument, and creates a dictionary of strings. The argument of strings contains data that represents Experiences. The keys in the dictionary will be the year of the experience, while the values will be the companies, stored as a list. You may assume that all experiences passed in as arguments never have two experiences with the same company and year. Items will be added to the lists-as-values in the order they are processed in the incoming list argument. The function should return the dictionary. For example, if you had the following function call:
load(["software engineer,IBM,1996", "cashier,Safeway,1983", "architect,Microsoft,1996", "advisor,GMU,1996"])
It would return a dictionary, when printed out, that would look like:
{"1996":["IBM", "Microsoft", "GMU"], "1983":["Safeway"]}

So I need to go through this set of about 20 programs and convert them to SQL.

The problem is they were all hastily written in Microsoft FoxPro and FoxPro is the retarded bastard child of SQL

I know neither language, where exactly should I start? I have awhile to do this (He wants good progress in 3 months).

I think it would be best to learn SQL first since Fox is just slightly different SQL. I already did some research on good books, but is there any websites that will give me easy tasks to do until I learn?

Essentially I learn best in a classroom setting. I am already looking into edX

{code] Write a program that calculates the sum (with precision of 0.001) of the following sequence: 1 + 1/2 - 1/3 + 1/4 - 1/5 + … [/code]

Self-learner here, how would one approach this? I am not sure how to switch those + and -. My first thought was to assign a + to one bool value and just switch it on and off as program goes, for every true write + and for every false write -, am i correct?

>>59268429
(-1) ^ n

0 -> 1
1 -> -1
2 -> 1
3 -> -1

and + a 1 for the first bit

Is it possible to average 2 ints in C?

>>59268970

 int x=1, y=2; float average = (x + y)/2

(I don't actually know C but why wouldnt this work)

>>59268902
In this case, it means it is much faster and uses much less memory than any alternative. Imageboards are all written in slow languages like PHP and Python. The native Go thumbnailing is nowhere near a solution in C with Go bindings.

And in case of hydron, it is an (eventual) Hydrus replacement. Hydrus is written in Python and can occasionally take a good 10 minutes from boot to operational state, imports are slow as fuck and it can't scrape tags from boorus in batch.

>>59268872

>>59268968
First two iterations do 1 - 1/2 instead of 1 + 1/2. Ignore the 1 at the beginning and add it back at the end. It's not part of the harmonic sequence.

>>59269072
The internal representation of 32-bit float reserves 23 bits for the significand:
https://en.wikipedia.org/wiki/Floating-point_arithmetic#Internal_representation

This means the largest integer a 32-bit float can represent accurately is about 2^23 or around 7 digits.

Your idea would work with double precision.

Hey /g/
I'm trying to write a NEAT implementation from scratch. Up to now I've read the main paper from Kenneth O. Stanley but I'm left with some questions.

1)The paper doesn't mention it but, by the logic with which crossovers happen, it makes sense for neurons to have an innovation number.
So do neurons have an innovation number? And if they do is the innovation number shared with the connections or specific of the neurons?

2)When the net structure changes how do connection "feed" the network, or, to better explain myself, by what order is the infromation fed forward? (pic related)
