If I want to implement malloc, and I want to merge/defrag some blocks (because there's no single continuous free block available), perhaps using memmove, pointers pointing to that data might get invalid since the data has been moved. Do I really need a special API to access the data (i.e. I can't just dereference the pointers mymalloc() gives me)?

>>52212768
If negative numbers don't exist then numbers themselves don't exist.
>>52212820
He means you can't have a negative number of things, which is correct, but we use negative numbers to represent data (.e.g. -5 meters above sea level) which just translates into (5 meters below sea level), but it's useful to keep the same reference point when referring to data.
So, if negative numbers are a meme, it is a useful meme.

>He means you can't have a negative number of things
ambiguous definition, you can have a negative amount of money. you can have a negative amount of charge.
>>52212968
>You can hold a positive number of things in you hand
That's only because the meaning we have given positive numbers applies to that situation. Numbers themselves don't inherently have any existence outside the realm of symbolism.
>>52212987
>you can have a negative amount of money
no you can't, you just have a positive amount of money that you owe to someone else
>>52212987
>you can have a negative amount of money
No you can't, you can owe somebody money you don't have. Using negative numbers is just a neat way to represent it.
>you can have a negative amount of charge.
A substance that gains electrons becomes negatively charged, while a substance that loses electrons becomes positively charged.
A substance never has a negative number of electrons.
>numbers exist
Lay of the drugs for a while
>>52213046
>no you can't, you just have a positive amount of money that you owe to someone else
that is the definition of a negative amount of money. it sounds like you can't explain what you mean because you don't even understand your point.
>>52213047
>A substance never has a negative number of electrons.
It has a negative amount of charge though. you're trying to shift the goalposts by changing the subject from charge to electrons.
>>52213109
>that is the definition of a negative amount of money
so the definition of "negative" relies on "positive", meaning that negative numbers don't actually exist, they're just a nice way of separating positive numbers being used for different purposes
>>52213133
you can apply the exact same logic and say that positive numbers don't actually exist.
>>52213145
at which point you've just redefined the meaning of positive to negative and vice-versa, rendering the entire exercise pointless

>>52213109
>It has a negative amount of charge though. you're trying to shift the goalposts by changing the subject from charge to electrons.
The charge refers to the number of electrons it gains or loses. It can never have a negative number of electrons.
Negative numbers are just a useful way to represent data, you can never physically have a negative number of things.
You can have a positive number of things, but never a negative number of things.

>>52213191
exactly. the clear result is that positive numbers are no more valid or real than negative numbers.
an ill thought through statement like "negative numbers don't actually exist" or "positive numbers don't actually exist" is just a lack of understanding of the nature of numbers. this is apparent when you ask for a clear and unambiguous (I won't even bother to use the word rigour) statement of their point. it always boils down to dumb examples and dumb bullshit.
>>52213291
Yes, you owe the bank 500 dollars you don't have. The minus is just a neat way to represent that.
>>52213277
If I have -500 dollars it means even if I got 500 dollars it would be taken away, leaving me with 0. If negative numbers were a "meme" then I would have 500
>>52213277
>You can have a positive number of things
That does not mean positive numbers exist. I can define two new words foo and bar, someone who is "foo" means they have an apple, "bar" means they do not. Does that mean the state of foo exists and bar does not?
>>52213317
they're just more valid because they're the ones we used to create the negative numbers, if it had been the other way around then positive numbers would be less valid, but, as it stands, negative numbers are a meme
>>52213336
The minus represents that you owe the bank 500 dollars, it doesn't actually mean you have -500 dollars.

People need to understand that although minus is useful for representing data, it's just an abstract idea.

As are positive numbers.
>>52213483
Positive numbers can be used to refer to things that exist, negative numbers can't.

So? The numbers themselves do not, hence being abstract.
I'm developing an exchange website for a niche mmo I'm playing with django/python/sql.
There's no centralized marketplace, so all trading happens at player shops or player to player. Besides commodity raw materials, the economy runs almost entirely off player-crafted items which are so highly customized that players basically have to requisition anything they actually want directly from a crafter as it's not just a sword, it's a sword with these runes and this enchantment etc..
This creates a space for an exchange between crafters and buyers to connect the two rather than everyone spamming trade chat on a one in a million chance the crafter with the patterns to make exactly the custom item you want is online, paying attention to trade chat, and willing to craft it for a price you can afford.
The way it works right now is crafters can contact me for an account (I want to do a little vetting), and then they log in and their profile has a big list of every pattern that mirrors the way it's laid out in game, so they can go through and check off every pattern they can make (these map to arrays where every pattern has its own index number). Then on the other side buyers can custom order an item they want made and the price they're willing to pay for it (it stores these as an array of ints that map to each of the patterns). The crafters then see all buy orders for items they are capable of making, and if they are willing to do it for that price, they claim the order and it disappears from the list.
Now I'm in the process of adding an order fulfillment element that will show when their buy order has been claimed by a crafter, and when the item is ready and which shop to pick it up. My major problem is I don't have access to in-game information at all, so it's impossible for me to know which shops have open space available for crafters to post up the completed orders.
(Cont'd)
>>52213565
Ignoring numbers entirely.
You can add items to an empty list.
You can't take away items from an empty list.
>>52213647
You can't add items to a full list.
You can take away items from a non-empty list.
>>52213674
>You can't add items to a full list.
>You can take away items from a non-empty list.
Correct. We've found something we agree on.
>>52213635
So in trying to figure out a decent way to allocate crafters posting up the items for sale, I've had a few different ideas but I'm open to hearing others.
Idea #1: Periodically rotate which of my shops I tell the crafters to post it
Idea #2: Fill a shop 3/4 full and rotate to the next shop hoping that by the time it gets back around to the first shop the orders have all been picked up
Idea #3: Let the crafter figure out which shops have open space in-game, and rely on them to communicate the correct shop to the buyer (don't like this one)
Idea #4: Rotate to a new shop every time
I'm trying to control a 8-bit shift register IC with an AVR microcontroller. I've connected a 7-seg. LED display into the outputs of the shift register.

void SReg_Drive(unsigned char num) {
unsigned char i = 0;
unsigned char bit = 0;
/* Drive shift reg. clock pin to "0" */
SREG_PORT = (SREG_PORT & ~(1 << SREG_CLOCKPIN));
/* Loop through the 8 bits of input byte */
for (i = 0; i < 8; i++) {
/* check if bit #i of input is "1" or "0" */
bit = (num & (1 << i));
/* if "1" set shift reg. data pin high */
if (bit == 1) {
SREG_PORT = (SREG_PORT | (1 << SREG_DATAPIN));
/* if "0" set shift reg. data pin low */
} else {
SREG_PORT = (SREG_PORT & ~(1 << SREG_DATAPIN));
}
/* Set shift reg. clock pin high, wait and set back to low */
SREG_PORT = (SREG_PORT | (1 << SREG_CLOCKPIN));
Delay_ms(1);
SREG_PORT = (SREG_PORT & ~(1 << SREG_CLOCKPIN));

Negative numbers may not exist, but they help by relating real world values with values of debt or depth. If we didnt use negatives, real life calculations would take a bit longer to explain (I have 1000 real dollars but I also have 5000 dollars of dept)

I'm thinking it should try to simulate 3 turns ahead and try to pick the optimal choice without explicitly knowing what all the variables is.

All of your ideas will fail if no orders have been picked up. Isn't there a way to tell if the buyer has picked up his/her item? You have to know the amount of free slots in order to assign a crafter to one.

There's no communication available between the game servers and my website, so manually looking at the shops is the only way to tell which have open spots.

Threadly reminder that you should not refer to the act of programming as coding. It is improper and makes you look like a 15 year old
You are a programmer, not a coder
Software Alchemist is GOAT
Developer is okay
Magician is okay
Software Engineer is okay
Software Architect is okay

Like in #2, add an error margin to your shops for those edge cases. Manually sync the amount of free/occupied slots in the shop by checking in game every once in a while.
Isn't there a way for the crafter/buyer to report back to the website that the item has been picked up?

Can some one please explain to me how the remove function in this example is working?
http://will.thimbleby.net/algorithms/doku.php?id=hash_table
it seems that if I try to remove a value, it performs the hash funciton, finds where my value fits in the hash table, then performs the hash function on it, recursively and never endingly. Am I missing something? are two remove function being used? one made by him and the other some js remove funtion?
please help

It hashes the data to get a slot, then it removes the data from that slot.

>>52214708
Yeah thanks. I know that it's removing the data from the slot it hashes to, my only issue is that this linethis.array[slot].remove(data);
Isn't it just recursively running the remove function? Or is it running another function by the same name? I have zero experience with javascript, so I really don't know what I'm missing
>>52214802
Different function, same name. Each slot is a linked list, and that remove function is operating on the list.

You are supposed to do them on C#.
I did them all, but I spend 4 hours after the 3 onward. I have no CS background or whatsoever, just doing online courses and reading books in my free time for 3 months now, mainly doing C# and javascript(i know i know)

Asking the buyer to hit a button when they pick it up creates more problems than it solves. They can hit the button and not pick it up; they can forget to hit the button after they pick it up. The crafter confirming it creates similar problems, although they are more reliable. The idea is to minimize the effort on both sides for the transaction to make it as frictionless as possible.
I could manually sync it up, but then the fault point becomes how often I log in and do that, and if I implement that then I'll end up buying more shops just so I can go longer without logging in.
Another problem is when a crafter is trying to do a bunch of orders at once. If I tell them to post all their orders to one shop then I get a problem of stacking all on one shop, and alternatively telling them to travel to each shop to post 1 item is a big hassle for them too.
The only feasible solution with no effort on either side is to have so many shops that any systemic problem I could iron out manually once a week or so. I have to pay for the shops once a week, so it creates lost opportunity whenever they sit empty. The only complete solution is to have the crafter decide where to post it, and have him put that into the website. I believe crafters might be willing to do that since if they don't tell the buyer where to pick it up, the sale won't happen.

How/when does one gets better ?
For the last few weeks I've been doing 10-15 exercises everyday and I keep forgeting basic syntax and doing stupid errors in the logic.
What is the normal time to solve a problem like that ? Do I have to give up programming ? Am I too stupid ?

How often does the number change? If it changes quickly enough, you'll just see all of the segments illuminated.

This is about chapter 4 or so in textbooks
ch1 being defining programming, or hardware background
Ch2 being variables or datatypes
ch3 being if and ifelse statements
and finally ch4 or so being loops and conditionals

My issue with dynamically typed languages is this: computers are fast but ultimately stupid. Many programmers who are starting out have issues with just how direct they have to be when programming, as we take our intuition for granted. Computers have no intuition; they only know what you EXPLICITLY tell them. Dynamically typed programs give the computer the choice to decide some pretty important decisions, which often leads to inefficient results and (in my experience) broken code.
>array of integers in a loop
>numbers being added to and removed from array
>array methods being called on what the computer decided was an array, since I defined it as a group of elements in brackets
>at some point, get down to one integer in the array
>computer decides it's no longer an array of integers, just a single integer
>program crashes because it's calling array methods on an integer
This actually happened.
>>52214970
it's normal to take long in the beginning
and it'll still be normal to take long later on when you tackle harder and harder problems
maybe start working on a slightly bigger project of your own and put the little bits and pieces together until you have more of an actual program

Well, I followed the libart meme tier (won a scholarship so it was free) and ended up being useless. I hate modern art now... and I hate all the "designers" just following the next flat trend. But I can't get my time back, so I guess I am better off learnign new stuff that are interesting and actually can provide something useful in the longrun
>>52215134
What language? Normally objects in a dynamically typed language don't change their type on a whim.
>>52214970
I'm not really sure how long it'll take. I remember that I was so used to expecting syntactic errors every time I compiled some code, and become shocked when I began to write code and have it compile properly 90% of the time. Once I was over that hurdle, I had to deal with the fun stuff: Logic errors
Protip: you never get over that hurdle

Free is good. I used to be an 'artist' myself then i switched career choices around midway through highschool.

>>52215291
Whats your skill level?
>>52215217
JavaScript.
Yeah, neither did I, but then it happened. I showed my TA and some class mates, and everyone was confused as to what the hell happened. On each iteration, I began to print the type of the array while keeping track of what was being added or removed, and it would say "object" up until it was down to one element, at which point it said was a number. It may have just been a freak accident. I've had weird shit like this happen in all kinds of languages, even statically typed ones.
In Java, I had the wrong answer given for some arithmetic process using the Integer class (was using lists) for about 1 out of every 20 tests I passed in, and it fixed everything when I used the intValue method to get primitive values instead.

>Thanks, you really motivated me.
No, this is not what you want. You don't want "motivation". "motivation" is a stupid buzzword to prop up children and losers. The time you're spending here asking us dumb questions about whether you're good enough to program or not would be better put to actually programming something, or reading a book, or talking about something programming related (even talking about one of /dpt/'s memes). Stop wasting time.
Any programming related reading material you'd recommend?
I want to learn.

What lang?
In Hindley Milner languages you kind of have to have it as a built in because it needs to have the signature something likeassert : bool -> string -> 'a, but ya usually it can just be made as a macro it's just that people would prefer to not write that macro and have it ship with the std lib because that's easy and works better across multiple projects (standardization is good)
