My father asked me to write a program that remotely controls other computers (cory) in the house. So he can able to take control the router settings w/o going to its "website" and be able to access to run commands in the other Windows machines from one program.

My idea is to make a server on my dad's PC and hide the client programs as Windows Services on the other computers.

But cause I need a plan I am using UML diagrams to do it but I hate drawing with a mouse so i do it "analog" with pen and paper.

Generate some files containing numbers, implement from scratch several sorting algorithms (merge, quick, heap)? and sort your files. Compare times.

I'm messing around with Emacs Lisp.
Empty list is nil, so this works:

(defun fizzbuzz ()
  (interactive)
  (let ((number nil)
        (fizzbuzz-list (number-sequence 0 100)))
    (while (setq fizzbuzz-list (cdr fizzbuzz-list))
      (insert (cond ((= (mod (setq number (car fizzbuzz-list)) 15) 0) "FizzBuzz")
                    ((= (mod number 3) 0) "Fizz")
                    ((= (mod number 5) 0) "Buzz")
                    (t (number-to-string number)))
              ?\n))))

I'd like to make it look even better.

>>55680716
>implying that is an indian accent

>>55680785
Common Lisp is better.

(defun fizzbuzz ()
  (loop for n to 100
        for res = (concatenate 'string
                    (when (zerop (rem n 3)) "Fizz")
                    (when (zerop (rem n 5)) "Buzz"))
        if res do (print res)
        else  do (print n)))

How could I make a Grand theft auto mod that will run on my Ps4's ofw.

Would I need special programs?

I don't know much about this stuff, but I'm thinking about getting my game data, and finding a way to code a mod menu into it, putting the altered data on a USB, and overwriting the old on the Ps4. I don't know how that'd work, or if it'd even work.

But is it possible?

Hi guys,

Sorry to bother you with this, but (in/with Docker) is it better to:

>contain scripts (e.g the Rails skeleton) in "open" "volumes" so I can edit them from outside the container and edit them whenever needed
or
>contain scripts in the container image itself, inaccessible from the host and rebuild the whole image every time

Sure I can still access the files from the host both ways but the second one is a little harder.

Also, if the first one, how should I move around the separate volume if using dockerhub or github or something?

>The matrix representing the returned transform is:
[ cos(theta) -sin(theta) x-x*cos+y*sin ]

I tried my hand at learning Python a couple of years back. I didn't really finish Learn Python The Hard Way. Now I am planning to start developing for Android. I have like 0% experience with Java and I only know about HTML/CSS. Should I dive right into Android development or go and learn Python first like I originally tried to?

Alright guys, i am not sure if i understand REST.
Please answer me this question:

is the "requests" module in Python a RESTful API? you can perform get, post, head, puts and delete requests with it, so it must RESTful right?

And CRUD would be something like JDBC for Java, yeah?

Yeah, no.
Cross compiling is hell.
There is no better way to learn to hate autotools than build a proper cross gcc.

>>55684010
What would you suggest then?

>>55683899
>Should I dive right into Android development or go and learn Python first like I originally tried to?
If your goal is pure Android dev, then you should start learning Java ASAP.

Alternatively, you could start learning C#. This would allow you to develop for Android in Xamarin or Unity while not using the clusterfuck that is Java.

>>55684067

>>55684067
Literally anything other than Java or Android

>>55683550
No. But they'd be useless anyway.
You have to actually write shit to learn *anything*.

>>55684090

>anything other than Java
but m-muh flappie bird clone

Seriously I want to reach consumers or is there a better way that possibly leads to early retirement for me? I'm not a capitalist I just want enough to get by, been freelancing for years and all that.

>>55684168
If you want income from developing, first you must learn to be a developer.

I recommended C# + Xamarin or Unity because you can dev it once and it'll run on iOS, Android, and Windows Phone, giving you a larger audience immediately.

It's probably the easiest way to get something working and on the Play Store / App Store.

>>55684248
I have some C# knowledge from college programming classes. If that's a viable path then I wonder how come I don't hear about it often? I am inclined to believe you I just want to learn more.

>>55684272
I write C# for a living, ask me anything.

>>55684272
Xamarin only recently became free (open source + free beer).

Previously, it cost about $1,000 per year for a license before Microsoft bought them and made it free.

That's why it's a new thing for entry-level developers.

They make their money on if you want to host your database/application on Azure, and if you want to use their hive of all Android devices ever created to do testing.

>>55684286
I have a macbook air and I already have android studio installed but I guess that's useless.

I have gedit, sublime text, what do I need to get started? Is ther a kind of Learn Python The Hard Way for C#? I really enjoyed that book that's why I keep coming back to it.

>>55684272
>I wonder how come I don't hear about it often?
Because it's boring.
A lot of the lol-enterprise Java stuff migrated to C#.
So there are plenty of C# jobs around doing mostly boring stuff.
Also, if you know C#, you know most of Java and vice versa.
(C# is the bigger language of the two, tough)

>>55684307
>macbook
Well, Xamarin Studio is probably what you'd want to go with.

Visual Studio would be preferred, but there's no OSX port for it at the moment, seeing as how it's based on the WPF framework.

I learned C# with Murach's, but there are probably better beginner books. Murach's focuses on database integrations and GUI creation, which is nice but Xamarin GUI is done differently than something like WinForms.

>>55684299
sounds interesting. Thanks. What's the best simple resource on C# + Xamarin/Unity?

>>55684308
Ive all but forgotten the C# college courses I took but I'm sure I can get into it again within a month.

If lets say my plan is to make a simple text editor, or a chat app, be it web based or app based, C# would be sufficient for me to get started right?

>>55684342
>What's the best simple resource on C# + Xamarin/Unity?
They have lots of example code and solutions you can compile and play with on their site. There's video tutorials, too.

I'd hesitate to recommend any random thing when their tutorials and documentation is solid.

>>55684348
Sorry to be a bother but would you mind posting a link?

>>55684307
>what do I need to get started?
A compiler and a .net runtime, so mono.
You can install mono (open source .net implementation, AFAIK soon to be merged with the open sourced .net) and use their compiler.

But for "professional" C# development:
Get a Windows machine and prepare to suck Microsoft dick.

>Is ther a kind of Learn Python The Hard Way for C#?
Sorry, I never used a C# book. I knew Java reasonably well and picked up the rest on the go.
I heard of 'C# in Depth' from John Skeet, but it's probably not a good introductory book.

>C# would be sufficient for me to get started right?
I know next to nothing when It comes to Web or App development.
However, whipping something up in WPF or WinForms should be manageable.
IIRC mono can't do WPF though.

>>55684413
>'C# in Depth' from John Skeet
I meant to say that book was written by John Skeet.
I didn't want to imply that I know him.

There are videos interspersed throughout, but you're certainly going to need to do some reading.

>>55684526
I'm that guy >>55684413

Just for the record. I don't think you absolutely have to do it in C#.
And I'm not sure that it's going to be a better experience.
Mostly because the Java Android API is directly supported by the vendor, and
I'm sure that there is a lot of material on that.
I guess having a cross platform intermediary is going to lead to some pain.

In my experience these "pancea" type that promises to cure all problems over a set of different platforms
tend to be more trouble than they are worth.
Be it ORM mappers or mobile cross platform systems.

People, and especially /g/tards, love to hate Java, so always take it with a grain of salt when they talk about it.

Also, depending on what you want to do, you can get away with a pure webapp.
Then you just open that thing in a Android browser to get mobile.
That way you could build up on the Python, HTML and Javascript you already learned.

Damn, I don't fall into any of those groups.

>>55685409
Damn, nobody asked you anything.

What is the best way to calculate the absolute Value of an integer (c++):

#define abs(x) ( (1 + 2*(x >> -1))*x )

or

#define abs(x) ( x < 0 ? -1*x : x )

>>55685432

inline constexpr int abs(int x)
{
    return x < 0 ? -x : x;
}

>>55685432
~x + 1
Assuming signed ints only

>>55685432
>-1*x
lol

#define abs(x) ( x < 0 ? -x : x )

A sequence of numbers is called a wiggle sequence if the differences between successive numbers strictly alternate between positive and negative. The first difference (if one exists) may be either positive or negative. A sequence with fewer than two elements is trivially a wiggle sequence.

For example, [1,7,4,9,2,5] is a wiggle sequence because the differences (6,-3,5,-7,3) are alternately positive and negative. In contrast, [1,4,7,2,5] and [1,7,4,5,5] are not wiggle sequences, the first because its first two differences are positive and the second because its last difference is zero.

Given a sequence of integers, return the length of the longest subsequence that is a wiggle sequence. A subsequence is obtained by deleting some number of elements (eventually, also zero) from the original sequence, leaving the remaining elements in their original order.

public class Solution {
    public int wiggleMaxLength(int[] nums) 
    {
        int pos = 0;
        int max = 0;
        
        for(int i = 0; i < nums.length;i+=2)
        {
            if(nums[i+1] - nums[i] > 0)
            {
                
                pos++;
            }
            
               if(nums[i+1] - nums[i] > max)
            {
                
                max = nums[i+1] - nums[i];
            }
    
        }
        return max;
    }
}

I figured out how to do it for positive or negative but I am having difficulty figuring out how to combine the two different patterns if it's negative first or positive. It's always random things like this that makes me struggles with algorithms. What it do?

No it doesn't, and it never should. A compiler should never optimize in a way that violates the expected order of operations, and for good reason

A compiler will not and should not ever reduce

red * 255 / 65535

to

red / 257

That is the programmer's job to do if he wants that, as it can have implications in the result. It's obvious that >>55686014 doesn't care about those implications, but the compiler doesn't know about that

You're going to have to explain ACE because I'm not getting the right results from google.
I don't know what you mean by C/C++, is that a specific certification?

>>55687768

Something like this for c / c++

How do I run test.py from poweshell script?

googling leads to people asking how to run python interpreter inside the poewrshell
but I am a simple retarded guy

>>55688176
Yes you need to have Python installed and just do:

python test.py

Where the file is located.

why isn't this true?

int a = b = 0;
int num = a & b; //0, false

0 & 0 are in their intersection, therefor the conjunction of them should be true.

>>55688257
>I'm such a math fag

>>55688257
For argument's sake, we'll just assume a and b are bytes
a = 00000000
b = 00000000

a & b = 00000000 & 00000000 = 00000000 = 0

>>55688257

0     0     0
0     1     0
1     0     0
1     1     1

and you run the interpreter by just typing 'python' into powershell

but it won't work if you didn't do pic related

just a suggestion, but run from windows either to Mac or Linux it doesn't matter as long as it's not windows. Everything will be easier.

>>55688257
What fucking intersection? & means bitwise AND in C, 0 AND 0 is 0 -> false.

I understand how it works, but it's wrong.

>>55688334
pic related, 0 and 0 are the same circle therefor to say 0 AND 0 is true. saying otherwise is like saying the null class is not itself.

Functionality for that already exists and is called remote desktop.
You would also be able to do it much quicker by having all of the computers connected to the network and have one of them be administrator of the network.

Misunderstanding the logical and operation. Every comparison that isn't True and True returns false. This is why we use & for bit masking.

>>55685067
C : can use pointers only
C++: can use pointers and refs

Just before You go further, here is in short:

int a; //declares variable a, allocates a with size of int, variable is undefined
a = 5; //variable is defined
a; // will give 5
&a; //gives address of variable in stack
int * ptr; //declares pointer variable ptr
&ptr; //gives address of where pointer is stored
ptr = a; //WRONG ! You are not assigning value to pointer
ptr = &a; //OK! You are assigning the address of a to ptr
ptr; // Gives address of a, therefore.
*ptr; // de-reference operator, it POINTS to value
*ptr = 10; // now a == 10 as well

*ptr + 1; //11
ptr + 1; // address of space AFTER ptr
*(ptr+1); // will try to de-refer to another element AFTER ptr, same as ptr[1], unknown behavior

Someone end my suffering. I have a little bit of experience with C, Java, and Python but I just can't decide.

theres difference in just installing all the shit blindly
and actually setting things up to how you like all the stuff

Anyone here ever work with a dysfunctional team? I've been on this team for about a month now, ~20 people randing from QA, Escalation, devs and a tech writer.

there is 3-4 senior devs but no one is the "top dog".

The product its self was inherited and is absolute fucking trash in terms of how it was built, talking 20k lines of javascript for the webclient.

everyone seems to agree that shit is wrong but nothing is being done about it, any advice? I don't want to bail (pay/benefits are good) but fuck am I stressed out after a month of this.

Is it possible to learn asp.net in 1 week?

>>55688595
>>55688601

Thanks guys. If I go for C I can just learn C++ at a later date anyway. Rust looks interesting though.

>>55688656

If you're learning ASP MVC and you already know C#, yes.

I have a couple of questions about C++:

frankly speaking pointers and references are just like soft and hard links under linux right ? (or at least vaguely similar)

and heres a long one please read carefully:

say I have a

main.cpp 

and a

foo.cpp 

and foo.h am I correct to assume that when I

#include foo.h

I can use only the things I declared in the header file ?

what is the purpose of include, coming from a java backround it does not seem like import, can you clear that up in maybe 1-2 sentences ?

>>55688655
Refactor the whole thing.
Hope that it's not pure JS.
Try converting it to coffee script.
If all fails, minify it.

>>55688695
Include basically does "copy and paste the contents" into the file that includes.

>>55688695
Separating interface from implementation.

How does one get out of programming limbo where you are stuck at doing medium programming skilled projects

>>55688707
Buddy the whole thing is JS + JQuery and an internal wrapper around a fuck ton of libraries like backbone, kendo, bootstrap. Its a total mess.

I 6 years experience doing this shit and this is by far the most fucked up thing I've ever seen, and people are just (slowly) building features on top of it. Because of the "pattern" the original idiots used, you basically have to just pile shit on top of shit to get anything to work too.

Pointers are just memory addresses. Nothing more. A pointer needs to have a type, because pointers support arithmetic.

Imagine an array of characters, each taking 4 byte of memory.

int arr[] = {1, 2, 3, 4, 5}

Now, a pointer,

int *p = arr;

Now, the pointer p points to the first character in the array. Now, pointers support arithmetic. If you increase a pointer:

p++;

Now, the pointer has shifted forward in memory 4 bytes, pointing to the second character. Thats why a pointer needs a type, to know
how much to shit. If it was a char, it would shift 1 byte, if it was a long long, it would shift 8 bytes, and so on.

If you go out of bounds:

ptr += 6;

Now, you are violating the memory rules and reading memory you should not, usually garbage.

Now, strings:

char *str = "Hello world!";

The str pointer points to the start of the string in memory. If you pass the pointer to printf():

printf(str);

Printf will start reading from memory and writing it to standard out until a null byte (\0) is found. If it isn't there, or you initialized the string in some retarded way, printf will read memory longer than the string and again start writing garbage to stdout untill a null pointer is found.

I only know other stuff like C++, Javascript, PHP etc. It's a course the uni gives, it's 1 week long and has a exam after it.

Start phasing out the older code base for new cleaner alternatives as you work on features. It's about the only way you'll be able to trick management into allowing a rewrite to happen.

One week doesn't seem like enough if you're coming into it from PHP/JS. C++ will help but it would be tough, IMO.

In python3, how do I get this to print a message when one is added?
This is comfy :

d[ip_address1] = d.get(ip_address1, 0) + 1

It just doesn't print a message like this ugly code:

                            if ip_address1 in d:
                                d[ip_address1]+=1
                            else:
                                print('reset/added', ip_address1, dest_port)
                                d[ip_address1]=1

What do I do? Keep old code?
