Well, there are really only two (or three) ways to create a line (or higher geometry like a square, cube, etc.) from scratch.
1. Reflexivity, i.e. weakening - you have a term in a context with some dimension, but the dimension variable is not used in the term
2. Univalence, which gives you a line from an equivalence (or vice versa)
3. Path constructors of higher inductive types, which of course aren't strictly necessary because of Church encoding

At least, I'm not using any framework and the server is in C.

I'm starting from scratch with a new idea, so forget about hierarchical tree threads.

>>57162362
Well, technically univalence gives you a path from an equivalence which can be "path-applied" to make a line, and if this equivalence is between paths you can path-apply again to make a square, and so on. But that's the gist of it.

daily tip: coding isn't the same as programming

>>57162454
I know what you mean but you can say it differently

What software should I use for creating and managing databases? I've been using MySQL for a few years but I feel like trying something new.

I recently started learning python it's so damn easy, I see a lot of people here hating on it, but I might use it for my next project, keeping track of a product line.

>>57162454
one time tip: coding is synonymous with programming

>>57162479
You could go to MariaDB, which is based in MySQL, or if you're looking to increase your job prospects, familiarize yourself with SQL Server and the surrounding tools (SSIS, SSRS, etc.)

>>57162454
The only people who say that are the fags who never got a formal education in programming or are in the first/second year of their degree

>>57162341
OK. So there's a misunderstanding then.
My idea was a function that produces results that cover its entire set of outputs in a cyclic way when you feed the function recursively. So to call back to the hashing idea. If I have a function f(byte i) and it produces a byte sized result. It won't repeat a result until it has gone through all the possible results. So if I feed it 2, 2 won't be produces before all other numbers 0-15 were produced.
That's the only criteria.

I mean I don't really expect anyone to know a name for this arbitrary thing I imagined. I felt it was worth asking though.

>>57162508
In the first year of my CS degree.

Can confirm, coding is not the same thing as programming.

Only faggots (read: apple users and related) code. Real programmers program.

Why? Because writing imperatives in a programming language has absolutely no "code" to it.

>>57162508
Well I'd say most people with formal education never do programming and just do coding. Because there's very few formal educations that teach programming in any reasonable way. Plenty teach how to write code and computer science. But neither of those fit the act of programming (planning and exploring development of a software/hardware product) well.

See my last post's name for details.

I'm writing an imageboard, and I'm a bit stuck on the "bump" system (showing the threads with most recent replies at the top).

I've got two table:

Threads(id, content, date, etc etc).
Replies (id, thread_id, content, date, etc etc).

How would I select all the threads, and order them by the most recent post to them? Any ideas?

>>57162943

That's not how you'd handle this.

>>57163052
Yes, if you assigned each thread a "last bump datetime" value.

At least, that's how I'd do it.

Each post would update that value, but if the thread is at bump limit or mod/admin saged, then the value doesn't update any longer.

in multiple threads?

>>57163100
Girls really don't care for that anymore it seems.

>>57163175
That's not really likely, depending on your time precision, but at that point they have the same "score" when sorted, so those threads would be grouped in indeterminate order in that place in the list.

Not really an issue.

So, what do you think of an imageboard with a semantic flow graph as UI?

Similar to mind maps and g/maps merged together into a chan.

>>57163230
Someone wrote one for 4chan threads at one point.

Looks neat, but ultimately not very user-friendly to browse with.

What are /dpt/'s recommended OpenGL textbooks?

>>57163264
>not very user-friendly
It depends how this has been done. What was it like?

The advantage (or not) of using a graph is to remove any kind of sorting, including time.

>>57163226
But you said all you wanted was someone to lean on and hug. There's nothing implicit in those functions that require a certain gender.

>>57163329
I'm not him. But generally there's a rather strict boundary for emotional closeness between men. You can talk about things and in desperate times you can have comforting physical contact but that doesn't work in the long run.

I'm not sure why. But it turns problematic all the time. So I'm presuming it's a romantic/sexual thing.
If girls can do this then maybe it's a male specific thing. But looking at research I'm not willing to jump to that before excluding that women are more bisexual than men is the true explanation.

>>57163204
It's not about time precision, it's about ordering of bumped threads.

If thread A and thread B both have 2 people bumping it at the same time they could get out of order and not be shown in the true order they should be the board page.

>>57163296
Get a reference textbook and use online tutorials. IMO that's the best way.

>>57163375
Women are more bisexual than men because women are objectively cuter. Even very straight women and extremely gay men have admitted as much to me.

Why are we spending so much time talking about sex? None of us ever have any.

>>57163399
>If thread A and thread B both have 2 people bumping it at the same time they could get out of order and not be shown in the true order they should be the board page.

That doesn't make sense.

If they are literally bumped within the same nanosecond, there really isn't a "true order".

Your "true order" only exists as precisely as you can measure.

In this case, it really does not matter which one is higher, and you could choose to break this "tie" with another measurement, such as # of posts.

>>57163432
That's why.

>>57163433
I'm saying the implementation can cause problems. PHP runs in a linear fashion and as such could cause some ordering problems. If you use your DBMS timestamp function you have to wait on the queries which can also cause ordering problems

Reached a weird point today /g/


I was hired at a company nearly two years ago because they wanted someone to help out. They didn't really know what they wanted me for but I got lucky in the interview and they thought I was pretty good.

I fixed up the codebase and gave it a better architecture. One that would scale and provide a base for other company projects. The people hacking the code weren't very good and I had to work hard to enforce standards and conventions. I spent a lot of time crafting a standard toolset and eventually things started looking good.

Today and all this week I was given a small older company project to convert over to the new libraries and when I finished I realised that the project that was only on my machine two years ago has grown into a colossus.

The project today spans 4 teams making 11 products over three continents. I realised that it's now too big for me to fully understand all of it.

It's like a mixture of happiness and sadness. I like what I did, but it doesn't feel mine any more.


Anyone experience similar /g/?

How do you keep feeling like the parent of a large project when it gets really big? It's like having a young kid that's only really into the stuff you show them - but when they get bigger they develop their own complex personality.

>>57163595
I dunno. It seems a bit simple to view it as cute vs uncute. Gay men are often very uncute and I can appreciate their aesthetic appeal. But I wouldn't say that makes me gay in any way. The statue of David isn't sexually attractive to me. But I can say he's well built, appreciate that on a hard work and fortunate genetics level (if he wasn't fictional). But I'd imagine gay guys can find him very sexually attractive despite how he's not particularly cute. And I also don't expect heterosexual guys to be attracted to feminine guys. I'm not. I'm only into that when what I'm presented with is convincingly female. Similarly heterosexual women have a wide range of people they find attractive. Some cute some very much not cute.
So it seems more like a coincidence that women are more into cute and happen to be more bisexual than it coinciding. But I haven't looked at what kind of guys/girls bisexual women/men are into. It's interesting.

first of all what on earth are you doing with a variable name like cardsInEachHandIterator

unless your professor is forcing you to compile with strict c89 then please use

for(int i = 0; i < whatever; i++)

or 'c' instead of 'i' if you're really autistic about sufficiently descriptive variables, i guess

second: you have to tell us what your program is trying to do. were you given those structs as a malloc() exercise? is it your solution to a card-counting problem?

I'm trying to create an array of hands, where each hand contains two integers and an array of struct cards

I'm just trying to allocate memory for it. But when I run this loop it sometimes crashes after 0, 1, 2, 3 or more iterations It's random. I don't understand it.

howManyHands is equal to 5
cardsPerHand is equal to 5
struct card *deck is created earlier and displays properly

struct hands dealDeck(struct hands *cardsInHand, struct card *deck, int howManyHands, int cardsPerHand)
{
    int allCards = 0;   // Goes through every individual card within the loop
    int handIterator = 0;   // Goes through every hand, as defined by howManyHands
    int cardsInHandIterator = 0;    // Goes through cardsInHand, as defined by cardsPerHand

    for(handIterator = 0; handIterator < howManyHands; handIterator++){
        cardsInHand[handIterator].currentHand = handIterator;
        printf("INSIDE1\n");
        for(cardsInHandIterator = 0; cardsInHandIterator < cardsPerHand; cardsInHandIterator++){
            cardsInHand[handIterator].cardsPerHand[cardsInHandIterator] = deck[allCards];
            allCards++;
            printf("INSIDE2\n");
        }
    }

    printf("INSIDE3\n");

    return *cardsInHand;
}

pretty much what always happens in these cases.

What is the length of deck?
What is the length of the cardsPerHand arrays?
What is the length of the cardsInHand array?
How could the iterator variables overflow them? printf them, and see if their actual values match your predictions.
What are they supposed to contain in a physical sense? You know that

struct card *cardsPerHand;

in struct hands is a pointer, which means the array is allocated somewhere external and that only a reference to that area is stored in the struct hand right?
And maybe post your entire code, it's hard to see where your coming from in any other case.

>>57164289
So less than (because there were almost certainly more women than men around during the war) 6.6% of men participated in the holocaust in some way.
So 1/20 or so.
What is it. 3-5% of people are sociopaths? Wonder how well those coincide.
Regardless. I don't consider that number to be worthy of the label 'most men'.
And buying i-shit can be a conscious tactical decision. You often find that people work like that. The price of an iPhone isn't as high as the gain they see from it. Because frankly for most people the difference between phones are marginal and the price doesn't matter that much. Me personally I wouldn't notice a difference at my income level. So if I felt my current phone was about the same but didn't give me whatever social approval I'd gain from an iPhone (which I doubt I'd get quite frankly) I'd get one.

I don't want to be stereotypical aggressive /g/ man but your variable naming is really really not good

your struct is named "hands." is it supposed to contain all hands? one hand? (a. it should be the latter, b. if it is then why is the word plural??)

cardsPerHand sounds like a count, not the actual array itself. if it's supposed to be a cards array then it should be named "cards." I literally can't think of a reason to name it the way you have

what is "currentHand?" why is it an int? why does it belong to a hand?

whatever. I'll let your professor handle that. (if he thinks this is fine then you have bigger problems than learning proper malloc usage.) reducing this to just the core issue,

theHands[cardsInEachHandIterator].cardsPerHand = malloc(sizeof(struct card) * cardsPerHand);

look at what you're feeding malloc().
malloc takes a size_t. (which is, for your limited purposes, the same as int).

all malloc() does is go ask the os for X bytes of memory, where X is the size_t you give to malloc().

sizeof(struct card)

will give you a size_t (number) representing the number of bytes in your card structure.

but then you multiply that by the cardsPerHand, which is not of type int or a size_t, but of type struct card*. i.e., you're multiplying a number (sizeof(struct card)) by a memory address (cardsPerHand, a pointer to a card). that's why you're getting "random" results, because the value of cardsPerHand is just whatever garbage you assigned in the previous loop iteration.

I'm not going to give you the correct code. if the above isn't enough to help you figure it out then e-mail your professor, because that would mean your fundamental understanding of what's going on is lacking to an extent not practically solvable by /dpt/ randoms.

>>57163989

It reduces binding of variables which gains performance.

>>57164384
Well the issue with networked physics still exists. Because it's the player interaction that screws the simulation if you have the kind of game where you care about that. Half life 2 did care about that to some extent in Half life 2 DM and it worked pretty ok. Sure it's not the most fantastic simulations going on but they're consistent until there's desyncronization due to player interaction. Outside of fringe cases like the extreme pressure garrysmod puts on them.

The gains you get are that you don't have to check if things are simulating correctly all the time.

God I just remembered something you might want to look at if you're interested in this. It's rather similar and iirc there was a Q&A question that was just about this.

Not a disgusting haskell person but. HOW?

In C++, if I have a few classes and want to add a new file containing globally accessible helper functions available to all classes, that do not need to be a part of an object or access any members, what is the cleanest way of going about this?

>>57164457
It's the other way around actually. GHC will only inline and rewrite (with the proper annotations, of course) if the required arguments are spelled out. That's why there are a few functions of the form foo x y = \z -> ... in the standard library.

>>57164526

There's no 'privacy issues' anywhere unless you're sharing only parts of the source (and you can't share only parts of a file for some reason).
Here's a good set of header only libraries to affirm the belief that writing everything in a single .h (or any other extension) file is fine.

I've defined earlier cardsPerHand to be an int, there is indeed a cardsPerHand inside of the struct which is a struct card which I now see was a terrible naming decision but the compiler recognizes that they are different. Even so, doing what you said hasn't changed anything.

    int howManyHands = atoi(argv[1]);
    howManyHands = 5;
    int cardForEachHand = atoi(argv[2]);

    struct card *deck = malloc(SIZE_OF_DECK * (sizeof(char) * CHARS_INSIDE_CARD + sizeof(int) * INTS_INSIDE_CARD));

    struct hands *theHands = malloc(sizeof(struct hands[howManyHands]));

    int cardsInEachHandIterator = 0;
    for(cardsInEachHandIterator = 0; cardsInEachHandIterator < cardForEachHand; cardsInEachHandIterator++){
        theHands[cardsInEachHandIterator].cardsPerHand = malloc(cardForEachHand * sizeof(struct card));

It sounds to me like he's doing OOP. And he's inexperienced. So I'm recommending a static function rather than just (presumably namescoped) global functions since in my experience teachers prefer that. And it fits his use case more automatically he hasn't said he wants global state. He wanted global access to some functionality. If I were to recommend global functions he might use global variables. Which is fine, but if he does that in a static class he will not be able to modify those members which will prompt him to ask about global members he can modify. In which case he can have a discussion about that when that's applicable.

Yes you're right anon. My experience with OOP goes as far as some semi shit C# and server side ruby. I understand what I would need to do if I wanted global variables or to access members of it, which is basically not any of that. I think for my use-case it's probably best just to chuck a few prototypes into a header file and use that, since only a few parts of my program are going to use it and there is nothing needed more than just some void functions that accept nothing. I'm already making use of namespaces, btw.

There's this idea that there's a perfect way to do everything, but we end up doing the most roundabout stuff to implement these 'perfect' solutions which then causes other things to break.

Fixed point. A shit load of what you use following point for you can do with fixed.

>>57165596
Sounds like a bunch of oopinloos.

>>57165714
Too bad it uses 4 times the ram

>>57165739
Not my site m8
Still, I'd enjoy watching you struggle to find even on exploit

>>57165762
No hardware implementation. What exactly is the problem with floating point? I know the precision issues, but if you understand the limitations you can work around them, or use a software based implementation.

Not down. It was just a prototype. The real thing is coming soon.

>>57165789
Fixed point is just an integer, representing a decimal number

Lisp
Learming is painful

>>57165780
It doesn't, actually. It uses precisely as much ram.

>>57165714
>Dynamically compiled
Useless. Then you have to ship the libraries which makes it even larger.
>statically compiled, it's very slightly smaller than the equivalent C program.
Not if you statically link against musl.

>>57165804
Floating point math exists in hardware. Why would that be the case if what you're saying is true?

Clearly you're wrong.

>>57165824
Source please

>>57165829
I haven't tried against either musl or uclibc, true.
>Lmao X!

Ebin.

>>57165804
>what is division and multiplication
Multiplication requires fixing decimal point and rounding (or you can truncate, who cares).
Division requires software implementation, you can't just divide.

I've been stuck on this problem for a bit. I want to rotate the letters by the number of length, but then I don't meet the requirements. I guess I need to use bubble-sort or something?

I want to learn some of the new programming languages like rust or go but I think it would be just waste of time.

Should I?

>>57165889
Nope.

You can either be fast or right

>>57165875

You're supposed to be swapping though.

>>57165927
>WEEB SOCKETS
Ehhhhhhhh?

>>57165932
You can be fast and right if you put the time into it. You are just a walking false fact machine.

I'm not putting any thoughts into this but have you considered if you're just supposed to show tail recursion? So:
Check if n=0 if it is return otherwise
Call the function with str+1 (note, pointer math) and n-1
Swap the characters str[n] and str[0].
close function.

I hate how they make you do stuff like this. There's so many better programming tasks to start with than trying to figure out recursive functions.

>>57165525
>>57165953
Wouldn't happen with fixed point

>>57165889
Not a waste really. It's good exposure to new ideas.
But is it the most productive thing? Probably not.

>>57165953
Not right now you couldn't. Fixed point is slower on any significant scale.

Why do I keep getting "dict is not callable" in Python 3? I'm running dict(zip(list, list)

>>57166407
because dick is not an object

>>57164194
This is really neat. Any source available?

>>57164194
bretty neat. I've just been looking into playing around with some fractal stuff. you have any good docs/links for the math and implementation of an l-system or IFS? what did you use to draw it?
