How do idle games continually increase player's cash/resources/progress?
Say I have a 'cash' row in the users database, how would I go about giving all users say 10 coins every 24 hours?
Surely running something akin to a cronjob that traverses the whole table and updates all the rows seems slow as hell.
I have thought about tracking the last timestamp the user accessed my website, and calculating the resulting eventual amount of cash to give him the next time he comes back.
I hope that last sentence made sense.

2. Suppose that instead of always selecting the first activity to finish, we instead select the last activity to start that is compatible with all previously selected activities. Describe how this approach is a greedy algorithm, and prove that it yields an optimal solution.
>Selecting the last activity to start that is compatible with all previously selected activities is a greedy algorithm because, firstly, the choice you make doesn’t depend on the outcome of any subproblems. Secondly, because you will always only be selecting the last activity that starts, you will always only have one subproblem. Thirdly, this means that the greedy algorithm will allow you to select the optimal activity very quickly. These are all of the properties of greedy algorithms.
>Selecting the last activity to start that is compatible with all previously selected activities will always yield an optimal solution. There may be other equally optimal solutions, but no other solution will be more optimal. This is because selecting the last activity to start that is compatible with all previously selected activities does not give the resulting subproblem less time-space than if any other selection was made. This means it’s an optimal choice. Repeating this on the resulting subproblem will continue to result in optimal choices until no other activities can be selected. The optimal choice and optimal subproblem solutions combine to result in an optimal overall solution.
did i answer this well enough? the question doesn't strike me as him wanting me to actually write the algorithm, unless that's what he meant by 'prove'. also, did i prove it well enough? the problems referencing the activity selection problem https://en.wikipedia.org/wiki/Activity_selection_problem which we solved in class by greedily picking the first activity to end. the question brings up a reversal, ie picking the last activity to start

Is there a way to detect whether or not an image is of a data table?
I'm working on a program for work that involves using OCR to read tables of alphanumeric data that are stored as images in PDF's. The tables may or may not have borders.
The tables I need are all in the same section of the PDF so I can easily dump every image in that section with something like XPDF, but I think that's wasteful since other images (graphs, figures) get mixed in and I would rather not waste time and money to process them.

A lesson on memeacadamy runnin through a language's syntax is like having the process of riding a bike explained to you, but you've never actually touched a real bike. You won't be able to actually do it until you try, fail and practice.
Memeacadamy doesn't teach you anything, it just gives you a false sense of accomplishment. Congratulations you successfully swallowed every spoonful of goop that they guided into your mouth while making airplane sounds... Now you're a chef, go cook a banquet for 20.

>>53866332
No wonder optimizing space was a matter... in the C++98 standard! But it awfully broke the convention that every container should be dereferencable through the [] operator. That makes vector<bool> a special class with a misleading name, since it is not a container per se. Even worse, you could implement a class equivalent to vector<bool> with better optimizations if you take advantage of larger word sizes.
A interesting read on the subject: https://isocpp.org/blog/2012/11/on-vectorbool

How is it arbitrary? When you subtract 2 out of 5 you get 3 - there is nothing arbitrary about that. And this is used to teach *everybody* to do arithmetic calculations faster not only kids who can figure out how to do mental math efficiently by themselves.

>Common Core STANDARD

Here's the standards:
http://www.corestandards.org/ELA-Literacy/
Where does it say that textbooks must teach the Second Amendment as being a non-individual right? It's entirely general skills that students are supposed to have, shit like this:
>Cite specific textual evidence to support analysis of primary and secondary sources, connecting insights gained from specific details to an understanding of the text as a whole.
Blame your district for niggering out and contracting with a shitty textbook writer.
>>53868723
Isn't it one of the first lines that the American people are obligated to overthrow it's government if it is to fall to corruption? Isn't that what a millitia does?
>>53868723
>"A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."
It's not as straightforward and clear as either you or this book present it. It actually sounds like it was formulated by a retarded person not familiar with the concept of ambiguity.
>>53868725
I have no doubt it's part of the master communist plan. I can't find anything specific in the standards, but I'm not looking very hard.

>>53868019

So you've confirmed that you're a retard and have literally no idea what you're talking about.
There are plenty of textbooks that go by the interpretation of the Second Amendment as an individual right. Especially considering that that interpretation was held up in DC v. Heller, a landmark Supreme Court case.
Cherrypicking shitty textbooks purchased by Bumfuck Independent School District isn't evidence of a conspiracy against the Second Amendment by education boards.

Common core sucks because it gets rid of AP Calculus. When I went to high school, there were two math tracks -- algebra 1, geometry, algebra 2, and pre-calculus; and a second path for people who had more than 2 brain cells that has algebra 1 taught in the last year of middle school, and AP calculus taught in the senior year of high school. Meanwhile, the smart kids in some other countries got to go one year further, taking the same differential and integral calculus in their junior year, and multivariable calculus in their senior year. Common core makes Algebra 2 taught in the senior year.
If we're going to make everyone follow the same standard, we should be raising, not lowering the standard. Make everyone take differential calculus in high school, it's not that hard.
>>53869127
Can confirm, was taught pre-calc in my senior year of high school
>>53869127
i took ap ca
>>53869127
i took ap calc 1 and 2. i dont think that's true
>Make everyone take differential calculus in high school
that's retarded
now another shader fails after a simple change, compiles fine on shdr.bkcore.com, glGetShaderInfoLog says nothing. for fuck's sake?
>>53869216
>>53869170
Common core applies to the current little buddies (4-8 year olds)
>>53868723
I would say it's not exactly wrong. All able bodied men aged 18-45 are considered members of the reserve / unorganized militia.
>>53869328
I know we're part of the unorganized militia, but that's not a requirement. If it were, then your frail little grandma wouldn't be able to have that .38 for protection.
>>53869314
oh, guess they're fucked then. i'm reading the wiki page right now and it reads like an advertisement all the way through
Still working on my imageboard server that I've spent way too long working on in comparison to what it's put out.
>>53869309
apparently it's a driver bug. i can't have the same uniform declared in both shader stages despite:
>It is legal to have the same uniform defined in different shader stages.
>When you call glGetUniformLocation, it will return one location. When you update the uniform with a call to glUniform, the driver takes care of sending the value for each stage (vertex shader, geometry shader, fragment shader).
>This is because a GLSL program contains all of the shader stages at once. Programs do not consider uniforms in a vertex shader to be different from uniforms in a fragment shader.
can someone redpill me on dynamic programming?

Html is my favorite programming language
>>53869651
have you thought about trying CSS
>>53869658
I have and I also tried Php and I found it be such a beautifully well defined structure language much better than C+
>>53868491
this has different behavior though
>>53869676
Php is the pinacle of coding and is what all coding languages strive to be.
>>53869607
There is no red pill. Just go to Wikipedia or pick up an algorithms textbook. Use dynamic programming wherever it may apply.
>>53869651

I am going to uni in the fall for cs and I have a couple years of experience programming in primarily C#. I just started my first big project but I'm wondering if I should write ditch OOP and write it in something like C. I want to be prepared for uni/real world situations, should I continue with OOP or write it in C.
It's something that could be done easily with either language but there will be a learning curve with C.
>>53869692
The task is to swap two integers. Only reason the Java function is using an array is, because you can't have multiple returns in Java.
>>53869651
plant
>>53869400
I know that feeling. Been working on mine for almost 2 years. Slowly rewriting it from scratch in a different language now.
>>53869794
I haven't had to do that much, but I have been stuck on fixing shit. Dealing formatting HTML before/after it's parsed and figuring out how it should be stored and handle in the db before and after is either harder than it sounds like, or I'm retarded and going about it the wrong way.
>>53869738
School and most jobs will expect you to be a good little sheep and use OOP.
I'm learning C coming from OOP and I'm wondering how I would implement this data structure in C.
OOP Pseudo code
class WordList{
property: ListOfDefinitions[]
property: WordList[]
}
class Definition{
property: Word
property: Definition
}
Here is my Csuedo code
typedef struct {
char* item;
char* description;
word_list_item* next;
} word_list_item;
How can I get a structure that would contain multiple lists of word_list_items. Sorry if noob, I have only been writing in C for a week
>>53869738
>>53869878
Not that you shouldn't ever use OOP, of course. It has its times and places. But if it's anything like my university you will be expected to do things like fill in an overengineered, poorly-designed OO ADT, which I suppose is a realistic working condition.
>>53869929
>fill in an overengineered, poorly-designed OO ADT
i literally just had to do this a few days ago. i felt like i was doing a fill in the blank for a childrens book written by a mildly retarded person
Why aren't you guys coding shitty apps right now making easy money
>>53869882
C doesn't have OOP support. If you find yourself trying to use a bunch of data structures to solve problems you're doing it the wrong way. Learn pointers, memory management, function calls, passing arguments, avoiding undefined behavior.
>>53870012
>using "code" as a verb
>>>/out/
>>53870012
It's been a while since I used Java, and am completely unfamiliar with the Android API.
>>53869882
Ignore this guy:
>>53870017
Data structures are key.
>>53869845
No, it is hard, if you have no experience with this. I think I've restructured the database layout about 10 times, before I got it right.
Should we move to 7chan's prog?
>>53870017
how is typedef/struct in anyway undefined behavior
>>53870038
So what go learn EASY money awaits you
C++ question. Can't access a protected member of a base class in a friend class.class A {
protected:
friend class Friend;
int x_a;
};
class B : public A {
protected:
friend class Friend;
int x_b;
};
class C : public B{
protected:
friend class Friend;
int x_c;
};
class Friend {
public:
void foo() {
C c;
c.x_a = 2; //error: x_a is protected
}
};
I know it's protected C++ but I told you he's a nice guy. What gives, how do I access x_a? I dont want a public set method because x_a should be set once then never changed. I can't set it in construction because C's are constructed in an array.
>>53870310
did you forward declare Friend?
>>53868397
If they're int's you can do it by swapping using bitwise xor.
temp ^= arr[0];
arr[0] ^= temp;
temp ^= arr[0];
But Java is a cancerous language,
>>53867753
The most I've done is linear algebra for graphics stuff.
I suck at math in general.
>>53870328
yes, forward declared above A. the method foo in Friend should be private also.
Who has made an esoteric language and is it worth it to make one?
>>53868019
Please tell me this isn't real.
>>53870397
yes
>>53870353
wait I sort of fucked writing that out but whatever it should be clear enough.
>>53868138
That's not too bad.
>>53868019 is way more fucking retarded.
>>53870464
That is a helper method, aside from formatting you've also only got one parameter for squareRoot while squareRootGuess takes an initial guess parameter
>>53868138
9 + 8 = 17
(17 << 0) + (3 + 8)
181
That's how I'd do it in my head lmao
Shaders are fun.
what's the best language to learn data structures in? like trees, graphs, etc.
I think Java, right?
>>53870588
C++
Is there anything like RDoc for C?

FFFFUUUUUUCCCCKKKK. I had a typo in the friend class declaration. Been staring at this for an hour.
Why do I never check the god damn basics first.
