I will repeat my offer once again. It has no value for experienced programmers, but you know, there are people who pay for code camps to learn. And my offer has more value than these paid codecamps.

Gentlemen. I'm looking for junior devs, pajeets, neets and anyone who is willing to become my slave. I have an offer that can be interesting for you.

I have a side-project with some commercial potential, but I don't have enough time to develop it myself. So, I'm looking for people of any skill level who want to practice and do job for me. I will give you tasks, and you will be free to implement them in any way you want — microservice hell is what we will create.

What is your benefit?
- You will get real tasks. If you are learning to code, real-world task may be good for you to understand what expects you in the industry;
- You will get some experience of working with a real client. You will see how real-world interaction may look like;
- My feedback and code review may help you improve your skills;
- You'll be able to add "I know how to develop microservices" line into your CV;
- When the project becomes profitable, you risk getting a low-paid laid-back job, you will have the opportunity to feel the pain of microservice integration and so on.

What is my benefit?
- Free coders;
- Opportunity to find people for future mutually-beneficial exploitation.

Interested? Contact me via [email protected]

how to access the addons page from firefox

with python or other language?

this url only works in firefox, but that's not a valid url
i tried

You can't. It used to be possible but Firefox had to remove this kind of feature because people kept installing malware.

>>62167707

>>62167905
you can't, it's a browser-specific tailored handler that servers an internal page based on the url, you can't access it from outside of the browser unless through an RPC or something like that but I doubt browsers even offeri t

>What purpose does a cripple have?
people are their own purposes
it's immoral to consider a person a means to an end
also cripples can do useful things
even the most physically crippled cripple can teach or program
even the most mentally crippled cripple can do heavy lifting, with sufficient strength training
and even someone crippled in both regards can serve as a table
>Besides being a burden to society, they're a burden to themselves.
everyone is a burden to himself
life itself is fundamentally a burden
you will never get more out of it than you have to put in to sustain it
it's a hard lesson to learn
what keeps us alive then
a basal and profound spark of will that can only be extinguished by the most sickening and destructive tragedy
how this spark feels to hold in one's heart is difficult to put into words
after all it's the premise of words themselves
why speak if you have no will to live--life being the singular interminable will from which all other wills are forged
>They know they cannot achieve all great things other can achieve.
life is not about progress
progress is merely a means to ever increase the probability of continued life
>Living for the sake of being alive is stupid.
don't call it stupid, it's why life exists at all
it's why you're here
it's why everyone is here
any other purpose anyone fulfills is secondary and in fact a distant consequence of that one original drive to live for its own sake
>You live to do great things that make you and the people around you proud.
greatness is relative to past experience
anyone who does anything they once thought out of their grasp is right to be proud of it, regardless of the achievements of others
for this reason pride is a fundamental experience that cannot be divorced from life

access(mutex){
  if (mutex->lock == UNLOCKED){
    mutex->lock = LOCKED;
    return UNLOCKED;
  }
  else return LOCKED;
}

i'm thinking of two threads running this at the same time
thread one would run the first line, immediately followed by thread 2 doing that first line. both of them read the mutex is unlocked. then thread 1 sets the mutex to locked, as well as thread 2 doing that right after. then both of them get unlocked returned from this function. how would you avoid that? or does that not happen?

Haven't done Java since college, recently finished up in a place I was at for a few years. Freshening up on the basics so I thought I'd do a linkedlist

Did this in about 10 minutes for a standard LinkedList

class LinkedList {

    Node head = null;
    Node tail = null;
    int size = 0;

    private LinkedList(Node h){
        this.head = h;
        this.tail = h;
    }

    private void add(Node a){
        this.tail.setNext(a);
        this.tail = a;
        size++;
    }

    private boolean hasNext(){
        if(tail.next() != null)
            return true;
        else
            return false;
    }

    public String toString(){
        String output = "";
        Node temp = head;
        int s = 0;

        while(temp != null){
            output += temp.toString();
            if(s != size){ output += ", "; }
            temp = temp.next;
            s++;
        }

        return output;
    }

    public static void main(String args[]) {
        LinkedList mylist = new LinkedList(new Node(0));
        int x = 1;
        while(x != 6){
            mylist.add(new Node(x));
            x++;
        }
        System.out.print(mylist.toString());
    }

}

class Node {

    Object data;
    Node next;

    public Node(Object dt) {
        this.data = dt;
    }

    public Node next(){ return next; }

    public void setNext(Node n){ this.next = n; }

    public Object data(){ return data; }

    public Node getNext(){ return next; }

    public String toString(){ return data.toString(); }

}

Not sure if this would go down well in an interview if I was asked to do one but it was probably the fastest I could do off the top of my head. How much work is ahead of me?

>>62168192
java is more complicated than c

but nonetheless more complicated
therefore perhaps it will be a positive learning experience

>>62168222
>Do you think a cripple using a motorized wheelchair controlled by his/her chin is a happy person?
that's for the cripple in question to decide
>The only goal they have is to wait until life's over.
so don't decide it for them

>>62168278
Before Christianity, people killed themselves because they were a failure. Christianity forces you to keep on living no matter how horrible the conditions are. Sometimes people cannot decide for themselves.

>>62168245
Its ok. I'm not sure why the tail would ever have a next in a linked list. You should also use generics instead of object, ie Node<Integer>. Also, you have standard interfaces that describe a list. Make LinkedList<T> implement List<T>

>>62168313
>Sometimes people cannot decide for themselves.

>>62167566
I'm waiting for government clearances to go through so that I can start working on a new project. In the meantime I'm amusing myself by learning antlr4 and making a short DSL that create CRUD application plumbing classes for you. If I get it to be beautiful and awesome enough, I'll then proceed to write about how this is an absolutely retarded way to solve the problem, and that what we really NEED is compiler macros so that we can hook our DSLs to the compiler to let it transform our code.

So far I've defined the grammar and I'm kinda happy with it.

type Widget (
  fields (UUID id "id"
          String name "name"
          BigDecimal costPerUnit "unit_cost")
  readers (
    getByUuid 
      query: "SELECT id, name, unit_cost from Widgets where id = ?"
      args: (UUID id)

    getByName
      query: "SELECT id, name, unit_cost from Widgets where name = ?"
      args: (String name))

  deleters(
    deleteByUuid
      query: "DELETE from Widgets where id = ?"
      args: (UUID id)))

This gives you a proper DAO with correct JPA annotations and the aforementioned methods, it gives you an immutable value class called Widget, and it gives you a builder that you can use to change state so that you can save state to the database.

If I get it to work I might add caching too, using the standard annotations for it. Dependency Injection would be necessary though. Just take a functional interface that returns a connection or something and I'll be happy.

The point of the exercise is that these classes are annoying to make: They're boring. We all know how they look. They're not where you spend your time.

So let's create these for us using this incredibly simple language, hit the compile button and have it compiled into java for us, and we're golden. (How I'll tell the compiler what file and package to put the classes in is an unsolved problem though. Not sure what is the BEST way to do it.)

>>62168313
by the way, in this post: >>62168397
i'm assuming you're suggesting sometimes we should kill cripples, which is disgusting and atrocious
if what you mean is that we shouldn't have to go out of our way to keep them alive, then i agree, see: >>62167619

I want to search collections of some millions of entries with ~100 characters each using a reverse word index and then filtering. Does there exist some software to do this reasonably performantly written in a compiled language without many external dependencies? Compile-time is okay if they can be statically linked. How is MySQL's search functionality from a performance perspective?

>>62168481
Have you tried grep?

>>62168423
Anyway the point here is to define something really nice that people wouldn't mind giving a go. Something that looks like it can save them time, that's easy to use, etc. Then I'll show you all the retarded bullshit you have to go through to compile it. Then I'll suggest a compile time mechanism to have the compiler execute arbitrary code at compile time at various places. This would mean that as you point javac at your Main.java class it'll see some sort of annotation or directive that tells it what macros it uses, and how to call them.

And show how all the annoying bullshit that you at one point had to deal with is now dealt with. There's no hidden magic to trick the compiler, it's all right there. And you could conceivably extend the compiler that way too by making it be able to say, deal with more literals. There are several possibilities, but my so far favourite is to tell javac directly about it when you compile by adding it to some macro manifesto that it consumes first, and thus what expansions you have in the java language is easy to deduce. Either that or do it like in Lisp.

Either way is fine.

>>62168481
Both MySQL and Postgres are good with text. But if it's a one-off, grep is likely faster.

>inb4 pointer to pointers
I don't like it either, but they're rarely accessed and I'll probably turn the whole thing into a ring buffer eventually. I'd reserve and call reset() if I didn't need it to grow and know its size.

>>62168707
>test

Yes, it has a race condition. You cannot guarantee the test and set operation are bundled in a single atomic operation.
You cannot write a userspace mutex.

Yes

>it'll eat up more time during an interview.

>>62168678
i'd love to talk about programming but unfortunately i'm currently tied up convincing a disillusioned person not to murder quadriplegics

>>62168700
How would there be benchmarks? You'd have to take into account the time of the loading operation, writing the functions, running it and getting the results back out again, vs grep just running over the files.

And that's WHY it's likely faster too. It's not that grep is superduper fast (though it can be), it's that it lets you do one-off jobs with a minimum of setup.

>>62168767

}

Would Peterson's algorithm even work on languages running in a VM?

I just started learning C and did an exercise to count blanks, tabs, and newlines, but for some reason the tab and newline values are wrong (tabs is always 11, newlines is always 0). What am I doing wrong?

 main () {
    int c, blanks, tabs, nls;
    
    blanks, tabs, nls = 0;
    
    while ( ( c = getchar() ) != EOF)
        if ( c == ' ' )
            ++blanks;
        if ( c == '\t' )
            ++tabs;
        if ( c == '\n' )
            ++nls;
    
    printf ( "Blanks: %d\tTabs: %d\tNew Lines: %d\n" , blanks, tabs, nls );
}

1b) sleep
2) if read mutex > 1 abort
3) read real mutex
4) set real mutex
5) dec read mutex
>>62168842
I have to rerun it for each query.
>>62168894
Don't do multiple assignments like that. Use {} for if statements. The excessive spaces look weird. Try fixing this, it might make the issue more clear.
On windows, newline isn't \n (it's \r\n), this might cause problems.

Is spoonfeeding allowed there? What does one read to quickly learn image encoding and transformation basics? Is there a good c# lib for that, or should I go straight into per-byte operations hell?

>>62168942
Thanks, it slipped my mind that I neede {} around the ifs.

>>62168953
>Don't do multiple assignments like that.
What is the reason for this? Is it purely cosmetic or does it affect the values?

>>62168894
C doesn't use indentation as syntax. It doesn't know all the if's are supposed to be in the while. In C's syntax, if a block has no curly braces to indicate what statements are a part of it, then by default only the very next statement is a part of it. So the C compiler reads your code like this:

while ((c = getchar()) != EOF) if (c == ' ') ++ blanks;
if (c == '\t') ++tabs; // Not in the while!
if (c == '\n') ++nls; // also not in the while

That doesn't explain the results you're seeing though. The results you're seeing are very strange.

>>62169016
>Thanks, it slipped my mind that I neede {} around the ifs.
I always add {} no matter if it's a one-liner or not. Otherwise, you might end up with obscure problems like you had.

not him but that's why you should put the star on the right and if you have a pointer type that's more complicated to express (i.e. contains modifiers) you should use a typedef

>>62165794
>>62165794
>>62165794

>>62168894
Just to mention, your loop will always overread by one character as EOF isn't set until you read the EOF character. Hence why C++'s ifstream has peak(), to set EOF before your loop condition check. Lot of ways to solve this, and many programming languages have had different approaches. None of which feel good.

Looking at your loop itself, the while should have the rest of the stuff in {}. Don't ever declare variables the way you have, but I imagine only nls is initialized to 0. "tabs" might be reading garbage or some kind of padding, though that's unlikely.

I don't do anything involving runtime input...ever, but the above are clear places the program isn't doing what you expect.

What's a good Prolog compiler / anything I should know in advance? Want to start learning it.

I'm learning C from pic related and am having trouble on exercise 2.1:
write a program to determine the ranges of char, short, int, and long variables, both signed and unsigned, by printing appropriate values from standard headers and by direct computation. harder if you compute them: determine the ranges of the various floating-point types.
I found the max value of char to be 127, which is of course 2^7 - 1. I thought unsigned chars were supposed to top off at a byte (2^8). Is my machine automatically "signing" them?
Also, I found the value of short to be 32,767 = 2^15 - 1, but couldn't get the program to display anything for int and long types (i essentially reused the same program for char and short, but swapping out types where appropriate). Here is the program to determine int:

I'm dissapointed, I was really expecting a piece of pracitcal C knowlege.

You shouldn't worry about it because compilers can optimize out the move.
But if you have a type which can't be move constructed...

How about just don't write this all on one line like a pleb? Lines are cheap.

int a, b, c, d, e, f;

That way it doesn't matter which side the * is on, so you can put it on the correct side (the side where the type is, because * is a part of the type).

Ugly and pollutes global namespace. Makes a program harder to interpret if its use becomes particularly infectious and non-local.

Generally superfluous and trivial usings and typedefs should be avoided. If I ever fork another project and intend to work on it, shit like that is the first thing I get rid of.

C babby here again. How would you do this?

>Write a program to copy its input to its output, replacing each string of one or

I wrote a program that has the same effect by replacing every blank that occurs after a blank with a backspace, but I didn't replace strings because the book I'm following has only been dealing with characters so far.

>>62169886

When you encounter another space, don't print it id the flag is 1.

I'm reading in one of the C books. I've been doing all exercises so far but now they started tagging some of them as group projects.

idea for a userspace implementation of mutex: a thread sends the mutex controller a signal letting it know it wants access, and then the controller adds it to a queue of threads. when a thread tells the controller it has left the critical area, the controller will advance the queue, and tell the next thread that it may enter the critical section

>>62170806
sounds fairly foolproof to me

>>62170806
This is more or less how it works, "mutex controller" being the kernel.

>>62170862
it strikes me as really slow. i'm sure the kernel would use xchg somehow but idk how it would do that

Currently learning SDL2 but the tutorial I've been following is SDL1.2.
What's typically used in SDL2? SDL_Surface or SDL_Window? I can't find any documentation on SDL_Window so I'm not sure how it's used.

>>62170915
At least kernel can put all the waiting threads to sleep until the mutex is free, instead of running them in busy loop. If anything, userspace synchronization should be lockfree.

Any recommendations for C++ windows application resources? Also resources to serve as a refresher for things I should try to do that aren't present in C and habits I shouldn't do that come from C?

It's been a few years since I've coded in C++/Java and I don't think I've ever actually made a windows application. I've been primarily focused on C, Assembly, and HDL. Recently applied for a position that calls for experience in C++, hardware/software interfacing, and windows applications.

Any C++ resource would recommend to use libraries that is cross platform, so you don't have to look for platform specific resources.
Effective C++ teaches you a ton of things about the "new" features that you can use in C++.
It also teaches you about safe vs fast and you get insight into why the things are designed the way they are.

What BASIC is the best BASIC?

How are gui libraries really made? I always thought that different operating systems just provided a set of widgets for programmers to use, but things like Qt and JavaFX/Swing have their own "look and feel". Do they just get given a surface by the operating system and they get to draw whatever they want on it? Is it done on the CPU or on the GPU?

they have shitload of drugs with similar names and they need a system where on each keystroke you see drugs with similar names

>work for huge company
>project has 5 architects, 2 tech leads, 2 developers
>I'm building a "microservice" for them which has expanded to 10k loc
>they still want to add more to it

Anyone else /corporatehell/?

>>62172891
>more architects than developers
what

>>62172891
My friend was assigned to review code his company bought from some other company and repair it. Turns out it had 1 million loc of pajeet code

100mb is peanuts on a modern system. Are you too poor to have 16gb of memory?

>>62172874
i see. that's a nice idea.

https://softwareengineering.stackexchange.com/questions/118759/how-to-quickly-search-through-a-very-large-list-of-strings-records-on-a-databa

there are algorithms to search fast in big databases you just have to choose the best solutions

another interesting read why GNU grep is fast

Wish I was joking. We're hire more devs but it's slow. Lead architect is a pajeet too.

what book should i buy to get better at cpp and oop design
i already can use cpp and made some projects with it, but im just guessing at prorgram design, i have cpp indepth , effective cpp and effective modern cpp pdfs
but
do they go into detail for program design or just best practice for using cpp features ?

not an argument, fuckboy

why not make hello worlds with 2 GB since you have so much memory?

Yes. Forgot to mention we have 2 "solutions analysts" as well.

Yeah, sure, why not? Good software engineering applies all the resources at your disposal to the task at hand.

their role is to design the system in those boring diagrams and choose the best stack, right?

thanks it looks like what im looking for

nice. since you have 16 gb of memory, let's make your browser use 10 gb for maximum efficiency

They design how each service and data store functions and interacts with each other. And yes they draw huge messy diagrams. They also write all of the technical user stories and write huge confluence pages, and have to approve all work that's completed.

                numerator = cashflows.Zip(yearFrac, (x,y) => (x * Math.Exp(y *-1*x_i))).Sum();

how do i do this in python i have no idea how lambda works

        numerator = sum(lambda x,y: x*math.exp(y*-1*xi),zip(cashflows,yearFrac))

you can laugh at this then tell me

>>62173140
what is yearFrac?

hard to do without knowing what the fuck is this shite

numerator = sum(zip(yearFrac, lambda x,y: x*math.exp(y*-1*xi)))

>>62173199
yearfrac and cashflows are lists

>>62173212
give examples

>i use a dark theme, but in PVRShaderEditor i leave it on the default white theme, the white is a bit distracting, since black is the absence of light why not have it be the background, and the things that should draw your attention (the text) are in white and other bright colors
Because studies have shown that we have an easier time making out black symbols on a white background than white symbols on a black background.

>brother calls and tell me to "learn python" to makeup for the fact that I missed the University enrollment

Is codeacademy good enough or should I read "Learn Python The Hard Way"?

>>62173261
doing the code academy python wont teach you any practical skill really, but you will help you learn what programming is and some feature sets shared by different languages

i'd do the code academy python course all the way through, and then do K&R C book, and then do your own projects. the last step requires you like programming.

Anyone here got modules to work in a useful way with C++?

I know clang can do it but it has a bunch of ugly and nebulous boilerplate, guess I could try to explore it.

>>62173261
read SICP

>>62173260
citing those old flawed studies is as ridiculous as the "human eye can't see more than 24 fps" type bullshit

the thin grey on white text those faggot web designers use completely nullifies any argument about contrast or legibility

maybe if you're an old normie fart who's used to black on white paper and can't into anything new the white background is better

>>62173261
beginner here.
While doing python from code academy try doing some little projects.. i mean like after every 2 units try to make a simple project on notepad++ or something and run it, it probably has errors, try to figure whats wrong and fix it, its ok to google/stackoverflow

>SICP
If is "Structure and Interpretation of Computer Programs "
From what I read
>The book was used as the textbook of MIT's old introductory programming class, 6.001.[5] This class has been replaced by 6.0001,[6] which uses Python.[7] Other schools also made use of the book as a course textbook.
as I understand it, Python only came in a later course.

>citing those old flawed studies is as ridiculous as the "human eye can't see more than 24 fps" type bullshit
Yeah, it's old so it must be bullshit. After all, only in the age of computers did people start wondering what would give better legibility. After all, it's not like we've been reading text on a background before computers, right? Nobody could've ever before wondered what kind of color combination would be better for reading. We just picked and stuck with a light background and dark text at random for thousands of years.

what program should i use on linux to make my own class hierarchy graphs and control flow graphs and stuff

In C++ I need to take input from stdin and store it in a string. The problem is that when I use this method

string in = "";
string temp = "";
while(getline(cin, temp))
    in += temp + '\n';

getline just hangs forever. I'm having this problem when debugging in Eclipse.

It's a probability, you fucking retard. Just because you have a low chance of rolling 6 on a 6-sided die 3 times in a row doesn't mean it can't happen.

Then give us a credible source that says otherwise. Until then you can take your conjecture and choke on it. If it truly is different from previous studies then in 40 years somebody would be debunking that, because this would be a rather easy topic to publish over.

>>62173615
Delusional? Because I understand how probability works I'm delusional? I swear, you white supremacists astound me. Your stupidity truly knows no bounds.
