# New & Revised /dpt/ Code of Conduct #
We want to ensure that the /dpt/ community, while large and diverse, remains
welcoming and respectful to all participants. To that end, we have a few
ground rules that we ask people to adhere to.
- *Be friendly and patient.*
- *Be welcoming.* We strive to be a community that welcomes and supports
people of all backgrounds and identities. This includes, but is not limited
to members of any race, ethnicity, culture, national origin, colour,
immigration status, social and economic class, educational level, sex,
sexual orientation, gender identity and expression, age, size, family
status, political belief, religion, and mental and physical ability.
- *Be respectful.* Not all of us will agree all the time, but disagreement
is no excuse for poor behavior and poor manners. We might all experience
some frustration now and then, but we cannot allow that frustration to turn
into a personal attack. It’s important to remember that a community where
people feel uncomfortable or threatened is not a productive one. Members of
the /dpt/ community should be respectful when dealing with other members as
well as with people outside the /dpt/ community.
- *When we disagree, try to understand why.* Disagreements, both social and
technical, happen all the time and /dpt/ is no exception. It is important
that we resolve disagreements and differing views constructively. Remember
that we’re different. The strength of /dpt/ comes from its varied community,
people from a wide range of backgrounds. Different people have different
perspectives on issues. Being unable to understand why someone holds a
viewpoint doesn’t mean that they’re wrong. Don’t forget that it is human to
err and blaming each other doesn’t get us anywhere. Instead, focus on
helping to resolve issues and learning from mistakes.

This (You) was paid for by the hard efforts of the users of 4chan.
I was making a program to read an html file and break it up into words. But the algorithm I made failed because Im not sure about the formatting of html files. Never worked with them before.
What I tried to was to find every instance of
> > </span>
but that pretty much missed everything.
I was gonna tailor the algorithm to find every instance of
> </span> <span
as well but before I do that I figured Id ask here since I could be taking the wrong approach to solving this.

THREAD CHALLENGE
Replace this class structure and implement the compare function in C.
compare a b must return true if a and b are mathematically the same number. For exampleinteger a = 7;
fixed b = 7.000;
float c = 7.001;
compare(a, b); // must return true
compare(a, c); // must return false
number is the interface of the class hierarchy

Actual attachments?
Make a MailMessage object.
Make an Attachment object with a filepath to the file you want to attach.
MailMessage has an enumerable property called Attachments.
You can call the enumerable method Add() to add a an Attachment object that references a filepath.
I thought it was a stupid question because it was about making something in VBA that's pretty entry level but I've been directed otherwise >>54358714

I suck at math but I'm decent when it comes to program intermediate stuff. If what you are trying to do isn't strictly math-related, you can find pretty much everything with a quick search. Even if you plan to do low level C stuff with pointers, where you have to understand how bit/bytes work, it should be pretty easy.
>>54359713
>>54359727
Well, it's not that I can't add attachments (here's the full thing if it helps: https://ghostbin.com/paste/3nuj8), I just need to add specific attachments from a filepath based on the selected items in a listbox.

I'm too spoiled by LINQ at this point, not sure if VB has an equivalent.
5 second hack example:foreach(var x in listBox.Items.Where(x => x.IsSelected))
{
mail.Attachments.Add(new Attachment($@"C:\temp\{x}.txt"));
}
Basically, you just want to say:
"For each item in this list that's selected, look for the accompanying file and add it to the email as an attachment."
Sorry, I'm not too familiar with VB.

>>54359874bool reference_compare(Foo *foo, Bar*bar) {

This doesn't work. If you have a class Baz that inherits from both Foo and Bar, pointer-to-foo-in-baz is not equal to pointer-to-bar-in-baz.
>>54359892
Yeah, that's it, where each item in the listbox has an associated attachment filepath. Like I said in the /sqt/ post, if I had [item 1] and [item 2] out of the listbox selected, I want the loop to grab the attachments that correspond with [item 1] and [item 2].
>Sorry, I'm not too familiar with VB.
It's fine, I'll either stumble on the answer on my own or someone will end up pointing out how easy the solution is to me.
>mfw my virtual file system crashes when I try to use it to open a file in a directory that has about 45000 files
At least it's a reproducible crash. Seems to always fail identically.
>>54359967
They're different bases, they can never have the same offset. Why would they ever have the same address? What are you actually trying to do?
>>54360000
What's the virtual file system for?
>>54360007
See if they are bases of the same object.
>>54359997
Well, it's pretty simple.
Just do a FOR statement through the list of items like you already did in your code, use an IF statement to check for an associated file, and if the if is true, create an Attachment and add it to the message.

I sometimes hear people saying that Ruby is functional, but whenever I open a tutorial for it, they start talking about OOP concepts right out of the gate.
I might have to learn Ruby for a job, but if I am going to be writing OOP code, I won't even bother.

>>54360054
>do you just "get it" at some point?
At some point you may think you've "got it" but a couple years down the road from there you'll realize you were about as retarded as it gets/
template<typename T, typename U>
bool dynamic_compare(T *t, U *u) {
return t && u && dynamic_cast<U *>(t) == u;
}
class Foo {virtual void foo(){}};
class Bar {virtual void bar(){}};
class Baz : public Foo, public Bar {};
int main() {
Baz baz;
return dynamic_compare(static_cast<Foo *>(&baz), static_cast<Bar *>(&baz));
}

>write a function in C that convert a string into lowercase
how can i do this in C?
my solution so far
char convert_string(char string)
{
int i ;
for (i = 0; i < strlen(string); i++) {
//what now ??
}
}
halp
>>54360223
Foo does not derive Bar, and it makes assumptions and is restrictive
Try it with 3 base classes
>>54360237void convert_string(char* string, size_t len)
{
size_t i ;
for (i = 0; i < len; i++) {
//what now ??
}
}
fixed it for you
>>54360237string[i] = string[i] - 65;
You also need to check if string[i] is a letter, your 'string' needs to actually be a string (so its type would be char *) and you should stop the for loop at strlen(string) - 1.
>>54360329
>- 65
I assume you mean tolower(...)

in c++ how does one read the whole file into 1 string.

>>54358891
Use split(), explode(), or whatever the equivalent is in your language to get an array of strings from the html file. Look for for "<span>" and "</span>" in the array then extract the array elements and rebuild the content from the strings in between those two locations using implode() or whatever is the equivalent in your language.

Question:

struct stuff *next;
struct stuff *test;

?
the strucure is global so all elements are initialized to zero already
>>54360355
no, I actually meant +32. It's the offset between uppercase and lowercase letters
for(int i=0;i <strlen(string)-1;i++){

string[i]=string[i]+32;

You'll need to learn Assembly for that.
And you /do not/ want to start with Assembly.

So we'll fork it and call it IronOxide or something, and remove the CoC.

In this moment, I am triggered. Not because of some phony Code of Conduct, but because I am oppressed by these white males.
>>54361560
the language is code, not the github repo and the community. The future of language is tied to its community though, but you can always fork if you think you know better how the language should be developed.

Guess again, shitlord. Check your privilege-checking privilege
>>54361372
Caesar isn't a mapping cipher, it's just offsetting, so you don't need two alphabets, just two offsets.
Direct tokenizing is probably a bad idea because you should be passing not alphabetic characters through untouched, not removing them.
Go through the string, store the start position, check if a char is valid, if so increment a counter.
Once you've reached an "invalid" character, apply the offset according to the counter i.e. length (odd or even), starting from the stored start point of course.
Then carry on, resetting the start position with the next char.

I don't think you can do that.
>>54361651
Why not, tard?
>>54361680
Both Apache and MIT licenses don't allow that.
>>54361694
Both apache and mit license explicitly allow that.
FTFY.

does the outline of the shell approximate a golden spiral?
>The nautilus shell presents one of the finest natural examples of a logarithmic spiral, although it is not a golden spiral. The use of nautilus shells in art and literature is covered at nautilus shell.
oh that's still fucking cool

Oh, I was thinking strip the license.
Is the COC even in the source code?
>>54361744
Maybe try renaming stuff so you're not reusing the same identifier in 3 different places, and people can actually work out what the fuck you are doing.
>>54360408
you have to malloc it senpai, but if it's global i wouldn't do that, instead just make it on the stack:struct new_struct;
new_struct.next = newstruct.test = NULL;
>>54361796
You're retarded if you can't understand that.

If you calloc it, all the fields will be initialized to 0 (aka NULL).
Seriously tho, just put it in a an init function.

Is desktop thread / desktop threads filtered or what?
what are the primary languages used for web applications?
>>54361817
yes thank for replying.
i know that i have to malloc.
my question was if i had to assign the value NULL or 0, since its already global, hence zero initialized
>>54361887
I'd rather he not have a pointer to memory on the heap be global, but yeah, calloc in an init is best.
>>54361828
Welp not only is the struct self-referential, but initialising those nested structs to 0 is also nonsensical.
So I can understand perfectly well how retarded it is, I'm just giving them a chance to make it sensible.
>>54361899
js (node, angular, whatever), ruby (on rails), python (+django, flask, whatever)
>>54361900
You know that you'd have to malloc it between those two lines, yes? Just making sure
>>54361887
calloc is a performance smell
>>54361820
Where the fuck do you think you are exactly?
Fuck off back to >>>/v/
>>54361915
>when you don't know what pointers are
>>54361902
If you're modularizing your code in .c files, just keep it local to that file only using a static global.
>>54361923
fuck off with your cargo cult programming terminology
>>54361973
Says the guy who unironically posts
>modularizing your code
>static global
>>54361973
>>54361922
all i am saying is instead of code A i would code B
Code A
stuff *create_node()
{
stuff *new_struct = malloc(sizeof(stuff));
new_struct->next = NULL;
new_struct->test = NULL;
return new_struct;
}
Code B
stuff *create_node()
{
stuff *new_struct = malloc(sizeof(stuff));
return new_struct;
}
>>54362048
modular is a proper word that means something
pretentious terms like "code smell" don't mean anything
>>54362055
that's not global then famalam
Code A is correct
if you have anywhere in your code something likevoid fun(stuff *s) {
if (s->next == NULL) ...
then it's not going to work as expected if you use code B
>>54362055
You'll get better performance by doing(long long int)new_struct->next = 0;
>>54362055
Nodes of a linked list should only be created by list_push or pop function.
>>54362087
"performance smell" means something
>>54362110
No it doesn't, you just made it up.
>>54362128
That guy isn't me.
>>54362128
I'm not him famalam
it's a big worry if you can't realize "performance smell" means "it'll hamper performance"

Hey ya'll I'm super new to programming and I'm trying to write a converter for decimal to hexadecimal
I'm having a fuckload of trouble visualizing how this is going to work.
This is practice for me so I'd really like a tip or two but outright telling me how to do it isn't much help
thanks for any and all advice
>Qualifications:

what do they mean by college course work can substitute for experience? do they mean if i took a class that used microsoft visual studio? everyone "develops software" getting a csci degree. how proficient do i need to be in visual studio and sql? what do they mean knowledge and experience on the SDLC?

What programming languages are growing in demand lately?
>>54362244
logo, perl and ada
>>54362244
just learn java if you want a job, it's the only language used in industry
>>54362228
>what do they mean by college course work can substitute for experience?
They mean if you have a course that uses the same languages and methodologies that the company uses, you can substitute it for experience
>>54362228
They mean if you've done interesting projects, contributed to research, or done internships.
Nobody gives a shit about your reverse-trawling B-tree program or that one course of C you took.
>Visual Studio
Enough to know the useful hotkeys and compiler settings.
>SQL
Big company? A reasonable enough amount that you can interface with the databases programmatically without issue.
Small company? Enough that you can create tables yourself in an organized and efficient manner and traverse them programmatically without causing huge performance issues.
>>54362225
First, learn how to convert decimal to hexidecimal by hand. You should know this already.
Second, write a program to do it.

Java, Python, C#, and SQL are all in high demand but I'm really concerned about future growth.
My mom basically spent most of my life unemployable because she didn't adapt to industry-wide changes and now no matter what programming job I get I'm going to be earning at least 4 times what she does
