Is this a good thread to ask questions in? I'm trying to figure something out in Vue if anyone knows anything about that.
I just started learning Vue like 2 weeks ago, so I'm not the best at it. And I'm using it for web development.
Basically, I'm on a page and I have an array that I'm using. Now I have a link to another page, which I'm using a <router-link> to do that, and I'm passing a few params with it as well. But on the page I go to I need to use that same array and I'm not sure how to do this. I've tried to find my answer from the Vue documentation and also just from google searching, but no luck.

thanks, guys! MS and W3C have a certification thing at EDX for front-end development. I noticed codecademy started me right with javascript whereas this wants to go through HTML5, CSS and then javascript.
Should I stick with this first and once the edx class hits javascript return to codeacdemy? I don't wanna get confused since they'll both be teaching two separate things.
i'm in for the long haul, I suppose! i'm super thankful sites like these exist.
has anyone received a certification from a site like courser, udacity or edx? I'm leaning towards edx or udacity just because they both offer certificates from Google, MS, etc. instead of just universities and even then, edx offers courses from Harvard and MIT which is nuts imo
thanks for this. so far, it hasn't been incredibly daunting but I quickly realized I'll have to do this everyday or I'll forget everything. my goal is to develop solid foundations primarily, so i don't mind retreading on things right now.
I'd say go through the HTML and CSS course first. JS main thing is that it can interact with the web and be used to make sites (you can run JS in your browser).
I have a certification from coursera for the first deeplearning.ai course and I'll get the second certificate soon. I'll be honest and tell you that I don't know how much value they have, but they should be able to tell people that you can learn things by yourself at least. Making a portfolio is the most import part, I believe.
Thanks! I'll finish up the edx course and refresh later.
how's that going so far? enjoy all the money! I was thinking the same about the portfolio. Can't wait to add my first project.
Has anyone done the third course of deeplearning.ai? I'm thinking of joining as an audit as there is no programming and I don't know if the case studies are worth it.
I'm finishing the second one and it's going nicely. I want to get to the fourth course soon as CNNs sound really interesting and are probably useful in my field. I'm not getting money from deep learning projects atm (still in college), but I might if I win some Kaggle competitions lol.
In Qt, is there a good way to apply the same code to a bunch of different UI elements?
For instance, I have four widgets that I want to fill with plots, all basically in the same way, only with a different image and of course different object names. Seems to be quite a waste to write the same code four times and just swap out the Qt objects, but I dunno how to switch out object names in stuff like ui.prePlot->replot(); dynamically.
Basically, I'd want to write a method that I just feed with the UI element and image and do all the rest in there.
(I also don't know the right key words to google around for this kind of problem, it seems :-( )
Thanks!
Edit: Disregard everything, call by reference

Hey, ya'll! I've started working with HashMap's and have been having a little issue with them and would appreciate any help. I've read the JAVA documentation involving HashMap and also searched online for a solution, but I can't quite find what I am looking for. The HashMap has two variables entered into it the name of the employee (The key value), and their randomly generated ID (The value I want to access when the key is entered). I already have a method that adds an employee to the HashMap and randomly generates an ID for them, it works fine and so does the method to remove the employee. I am then supposed to make another method where I would enter a parameter id and that would look for any id's matching it in the HashMap and remove them, then I would make a separate method called generateID to assign a new randomly generated ID to the employee name key.
My issue is that I do not know how I am supposed to type it out so I am referencing the id I want to remove in the method. If I do something like employees.get(id) or employees.get(inputName, id) it says it cannot find the variable inputName and so I don't know how to set it up properly. Below is a snippet of the code I am typed up. It's missing some of the other methods, but they all work fine. The only issue I'm really having is removing/changing the value of the id.

public Company (String name)
{
employees = new HashMap<>();

}
public String addEmployee(String inputName)
{
int n = randomGenerator.nextInt(max - min)+min;
String id = String.valueOf(n);
employees.put(inputName, id);
}
public String removeID(String id)
{
employees.remove(id);
return id;
}
public String generateID(String name)
{
}

In Java 7: Iterate over the key set and see what the corresponding values are. Replace the values you want with put().
In Java 8: Use map.forEach() to do essentially the same thing but using a lambda so you get cool points.
Are there a few people in here who are familiar with the Swift programming language? I've been teaching myself little by little over the last few weeks, and just want to make sure I don't clutter up the thread with inquiries if it's not a big language here. Thanks!
can any C monsters help me figure out what I'm doing wrong with my memory allocation ?
I have a struct that holds a char array, among other things.
I first malloc an array of these structs:
Then, in a while loop I allocate these entries and their character arrays individually:
My program is functionally complete and yields the results I want, but now I am trying to free this space to make valgrind happy. I have a clearRecords method:
I am getting free errors when I run my driver, however, and valgrind doesn't share much. Any tips on how I am supposed to free this correctly?

recList already has enough space for the records. You don't need to allocate again.
You create a record structure on the stack and then memcpy into the specific array address. Right now you end up freeing blocks in the middle of the array.
You do need to free each description in your design though.
Basically, loop through free the descriptions. Then free the array. You don't need to free each individual record just the list.

I'm trying to write a program that compares two arrays with integers and determine if they are the same
The code is not done yet (size is used because I need to choose between an array of size 8 or 10 which I will later add, and count will be used to compare the arrays)
The problem I'm having is
1. for the second array, even tho I'm writing the exact same kind of code as the first one, it lets me input one more number unless I set j<=7
2. I'm getting a 'c stack around variable corrupted' which as I understand means I'm exceeding the size of the array
Also, I'm not sure if the logic of the function even checks out yet ;p
Thanks!

You've got i <= 8 in one loop with the max index is 7 and j <= 8 in another loop again when the max index is 7.
Can I ask Unity questions here? I'm trying to move the player in their 2D UFO tutorial (3 of 9 videos) but the arrow key won't move the ufo.
Here's what isn't the problem:
1. Kinematic is not checked
2. Code is good (imported from the store)
3. Speed is not zero
4. Gravity is zero
My unity version is 2017.4.0f1
Thanks!

Right. Thanks! ><
Edit:
I ran into a problem with my approach, trying to think of a solution for it now, anyone has any bright ideas? ;p
Let's say I have two arrays
First array:
1
2
3
4
5
6
7
8
Second array:
1
2
3
4
5
6
3
8
My program checks the first index of the first array versus the entirety of the second array and adds 1 to the counter if there's a match, then does the same for all the next indexes of the first array. But the problem with my approach is I could have the same number appear a couple of different times in the second array and I'd have no idea of telling if the first array matches the second array.
I thought about creating a third array that does a count for each index individually but that seems like a bit of an overkill? I dunno
'Fixed' code
Code:
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
int comparearray(int a[], int b[], int size)
{
int i, j=0, count=0;
for (i = 0; i < size; i++)
{
do {
if (a[i] != b[j]) {
j++;
}
else if (a[i] == b[j])
{
j++;
count++;
}
} while (j <= 7);
j = 0;
}
printf("The count is: %d\n", count);
return count;
}
int main()
{
int array[8];
int array1[8];
int i, j, result, size;
printf("Please type the size of the array\n");
scanf("%d", &size);
printf("First array:\n");
for (i = 0; i <= 7; i++)
{
scanf("%d", &array[i]);
}
printf("Second array:\n");
for (j = 0; j <= 7; j++)
{
scanf("%d", &array1[j]);
}
result = comparearray(array, array1, size);
return 0;
}

Sorry just seeing this--I ended up realizing my mistake soon after posting and was able to fix everything by removing the allocation for individual struct objects as you said... I completely missed the fact that my initial malloc of the array held enough space for every object.
Thanks so much !
Are you trying to see if the arrays are the same or if they have the same set of numbers? There's a difference.
If the former, then you should be exiting the loop as soon as there's a mismatch. If the latter, then sorting the arrays first would probably be best (assuming you've already learned that).
I'm trying to see if they have the same set of numbers. They don't have to be in the same sequence or have the same number of appearances, just make sure that both arrays contain the same numbers
So let's say array 1 could be
1,2,3,4,4,5,6,7
array 2 could be
2,1,3,3,4,6,5,7
I'm not sure what you mean by sorting the array, could you elaborate?
If you sort the arrays from lowest to highest before comparing them, you'll have an easier time traversing the arrays and won't have to go over the same values more than once.
This way, you should be able to use a single while loop and an iterator for each array. There are only three cases to handle then: if the values are equal, less than, or greater. If the values are less than or greater, all we have to do is increment the corresponding iterator and continue searching for matches, because we know that the arrays are in the correct order.
Code:
while (i and j are less than size of arrays)
if (a[i] == b[j])
count++;
i++;
j++;
else if(a[i] < b[j])
i++;
else
j++;
What I would do is first check they are the same size, if not return that they are different then and there. Since this is C/C++ you can use sizeOf assuming an array with the same memory is of same size.
Then for each number in one array check that it exists in the other. Return false in the first mismatch. Return true in the bottom which will be reached if there is no mismatch.
E: Oh since you are only looking for membership ignore the first bit.
Then for each number in one array check that it exists in the other. Return false in the first mismatch. Return true in the bottom which will be reached if there is no mismatch.
E: Oh since you are only looking for membership ignore the first bit.
I actually just asked a friend and she thought of something else but her idea gave me a new one. I don't really care if there's more than one match so I just placed a break statement here
Code:
else if (a[i] == b[j])
{
j++;
count++;
break;
}This only solves half the problem tho. If the first array is the one that has the same number multiple times and it doesn't include all the numbers from the second array, I don't have any way of knowing.
I'll look into your method now. Thanks!

I'm working on a JAVA Homework where we have to create our first GUI with Swing and man... what a fucking pain in the ass.
I can get all four of my JPanels in the window (basically the top one is 4 radio buttons, the second one under it is a text box and a button, the thirst one is a list and the 4th one at the bottom is just a row of buttons)... They are all there but I can't get to resize properly. Right now they just completely fill the window. This is dumb and annoying.
Edit: Right ok... I think I finally got it to work with setPreferredSize but man this is still super clunky

Never heard of JAVAFX but it's a school so, as usual, they are always LTTP for stuff like that lol
Stopping by for a short rant:
People who merge in breaking changes without noting the breaking changes are incredibly annoying. Especially when there is a documented procedure on how we handle breaking changes. Now I've got to spend a day fixing broken stuff which is going to throw off my hours I'm logging on this project.

Why are they able to do this? You should be able to configure your build systems so that merges to develop are only possible after a successful build.
Problem: You are working on a branch. Team/Person b is working on a different branch and merges breaking changes that affect your branch. The tests and other gates for that build pass because master doesn't break but the changes affect your work. You rebase.
Now you have to spend hours fixing your branch. My worst case for this was I had a branch with upcoming changes that was relying on some internal library functionality. A senior team member decided to refactor the module and removed 'unused functionality' that I was of course using in my branch. Had to basically rewrite the whole thing and re-implement some parts of the old API in the new file.
Antagon it is exactly as Theonik describes. Except more developers besides me have been affected by this so a handful of us have breaking changes for our features we are adding. It wouldn't have been a problem if we were given a heads up at all.
Code:
void Display()
{
char flan[SIZE];
int count = 0;
pudding.open("beta.txt");
while (!pudding.eof())
{
pudding.getline(flan, SIZE);
while (flan[count] != '\0')
{
cout << flan[count];
count++;
}
}
pudding.close();
}Don't I know. The trifecta is scope creep, waiting on external party, and green lighting more projects than can be currently developed with your team size.
Has anyone here bothered to compile Quake III Arena recently in VS2017, I'm getting unresolved external symbol errors.
What are the errors? I've never compiled it with any version of VS, but i'm pretty familiar with VS linker and fixing linker errors so maybe it will be something obvious.
I dunno how many people here use unity, but you might also want to post that on the indie game development thread on the gaming forum.
There's also a lot of warnings but those don't really matter.
What does your link command line look like? You can show it by going into Tools > Options > Projects and Solutions > Build and Run and setting MSBuild project build output verbosity to the highest setting. Then after you do a build, Ctrl+F in the output window and search for link.exe and you should find the command line.
Can you also paste the declarations of the 3 functions? Just grep your source tree for all header files containing glConfig, GetRefAPI, and GetBotLibAPI (without the leading underscores)

From the link line, you can see that it's not linking in any quake .lib files. It's only linking these lib files.
winmm.lib wsock32.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib
So there are two possibilities:
1) GetBotLibAPI, GetRefAPI, and glInit are expected to be defined in some object file which is linked directly into the EXE
2) These 3 things are expected to be defined in some library which is not on the link line for some reason.
Couple of things:
a) Is all of this code you pasted from the file cl_cin.c? Or does some of it come from other files
b) I think you pasted the wrong thing for glConfig; You pasted the extern declaration, but not the definition. And in the spoiler, you pasted a function, not a global variable definition.
c) It looks like you pasted the definitions of the fucntions, but not the declarations. They should be in a header file somewhere with just the signature. For example it may just look like
void CL_InitRef( void );
But I'm curious if there's anything else on the line.
d) Can you paste the output of running dumpbin /symbols "C:\USERS\<UserName Redacted>\DESKTOP\QUAKE-III-ARENA-MASTER\QUAKE-III-ARENA-MASTER\CODE\DEBUG\CL_CIN.OBJ" | grep GetBotLibAPI
(If you don't have grep installed on your machine, you can instead upload the entire output to a pastebin)

Awful stuff, I guess key is to call it out early and often in meetings to give visibility to it.
When I saw it after you instructed me I though it may be something like that.
1 & 2) Makes sense.
A) The first three are about glConfig come from the class cl_cin.c, GetRefAPI and CLinit_Ref come from the class cl_main.c, and GetBotLibAPI and SV_BotInitBotLib come from the class sv_bot.c
B & C) Yeah I was a little confused by that.
This is all I found in regards to glConfig and I think it's from the OpenGL API.
Located in cg_public.h
Loacted in client.h
Located in tr_local.h
Located in tr_public.h
Located in tr_types.h
Located in ui_public.h

Code:

SV_BotInitBotLibHey just wanted to thank you once again for helping me. I kind of struggled with the project all week because I forgot I posted here and then checked your reply. I ended up Google'ing what lambda is and after working through it was able to finish the method as intended.
Yea sorry can you do the same for cl_main.obj and sv_bot.obj? If glMain is from opengl and the other two aren't in cl_cin.obj either then that won't have anything useful
Also, CL_InitRef and that SV_ function are both fine and not the problem, so don't worry about those
Edit: Wait do you mean to say CL_InitRef is in the same .c file as GetRefAPI? Is this file on the internet somewhere?

It's fine you're helping me, dumping is relatively easy. Here, you go. cl_main.obj dump https://pastebin.com/iF7UPaaX sv-bot.obj https://pastebin.com/7VucXs6L
Oh sorry about that, I think it's my bad but yes, what I'm trying to compile is Quake III Arena from id-Software on Github, here I'll fetch the links real quick.
Here is the general Git. https://github.com/id-Software/Quake-III-Arena
To get there go to the link -> code -> client -> cl_main.c.
Here is the specific class on Github. https://github.com/id-Software/Quake-III-Arena/blob/master/code/client/cl_main.c
Hi, need some advice on Octave.
How do I construct a Hull White tree for Pricing Options? I'm at a loss and I don't even know how to start. The option I'm pricing involves a Zt state variable (that follows a Ornstein Uhlenbeck process) and the payoff function is as follow:
Ultimately I'm suppose to figure out a payoff for when te=2, so I only require Z2. Even then, how do I derive Z2?
Also, the risk neutral mean EQ, is it correct that the way to implement this is to assign probabilities pu, pd and pm to the function contained within EQ?
Many thanks.

Ok so the first problem is that GetRefAPI isn't actually in cl_main.c. What is in cl_main.c is this:
Code:
ret = GetRefAPI( REF_API_VERSION, &ri );That is just a call to the function. What we need is the definition of the function. I searched the GitHub, and it shows up in various places. For example, in tr_public.h we have this:
Code:
refexport_t*GetRefAPI( int apiVersion, refimport_t *rimp );But that is not a definition, that is a declaration. A declaration just says "hey there's a function called GetRefAPI and here's the signature. You can call it, but since I don't have the code for it, the linker is going to have to figure this out."
A definition is where the code actually occurs. That is in code/renderer/tr_init.c. Which you can see here:
Code:
refexport_t *GetRefAPI ( int apiVersion, refimport_t *rimp ) {
static refexport_t re;
...
}What this means is that the important object file is going to be tr_init.obj. For any given symbol (function, variable, etc) exactly one object file should contain a symbol for it. That's what I was getting at with the dumpbin commands. I was trying to see "does this object file have the right symbol?" If it does, and the name is correct, you won't get an unresolved external.
So when diagnosing this kind of thing, you have to ask:
1) Which object file contains the definition
2) Is that object file being linked in
3) If not, why not? If so, why isn't the name matching?
So now that we know it should be in tr_init.obj we go back and look at the link line again. This time we're looking for tr_init.obj. And we see, it is nowhere to be found.
So this brings us to #3 above. The proper object file is not being linked in, and we need to know why.
I went to the top level of the GitHub repo and saw that there is a quake3.vcproj file. I opened it up in GitHub (not in VS), and Ctrl+F'ed for tr_init.c found that this project does not even compile this file. So it needs to be coming from somewhere else. Probably it's compiled in a different file and then supposed to be linked in to the final project. So I opened the .sln instead and saw that there is another project called renderer/renderer.vcproj and sure enough, this is the project that compiles tr_init.c.
So now we have a clue. quake3.vcproj is supposed to be linking in the files from renderer.vcproj, but it isn't. How is it supposed to link them in? Well, in renderer.vcproj we see this line:
Code:
OutputFile=".\Debug_TA\renderer.lib"So we can tell that it is supposed to be outputting a file named renderer.lib, and presumably this file is supposed to be linked into the final executable. Remember one of the first observations I made when I looked at the link line was that there are no quake-specific libraries.
So to fix it. The first thing to check is: Did you open quake3.sln or did you open quake3.vcproj? If it's the latter, that's the problem. Open the .sln file instead. However, I suspect you are already opening the .sln file.
This could be an issue with such an old version of the MSVC project file format not fully forwards-compatible with the new version, so when it tries to upgrade, information is lost. The reason I suspect this is because I don't see anything in any of the project files or solution files to indicate that quake3.exe (from quake3.vcproj) should try to link renderer.lib (from renderer.vcproj).
If you just want to test this theory out, go into quake3.vcproj, edit project settings, go to Linker and find Additional Input files then add a full absolute path to renderer.lib on your hard drive.
I suspect the errors will go away. If you want to do it the "right" way, probably in the solution file you need to add a dependency from quake3.vcproj to renderer.vcproj, and then in the Configuration Properties > Linker > General for the quake3 project, make sure "Link Library Dependencies" is set to Yes
