Yes, unfortunately. But Based Microsoft explains to businesses looking to make the switch that your job will remain intact even if you're maintaining some old pile of garbage Java application. .NET is the future.
Per Microsoft:
How to Get Started with .NET
Moving to a new technology is always intimidating for organizations. While .NET is very large, it is not that hard to migrate to. Since it will co-exist with your existing applications, there is no need to rewrite old applications. Simply write new applications in .NET and leave your older applications alone. However, there are several things you should do to prepare for your move to .NET.

then you can do a different challenge: calculate the cross total of the factorial of a given number.
i.e: 5! = 120 -> 3

If he didn:'t check all numbers he'd have to add a workaround for the number 2.
>>55111726
>he'd have to add a workaround for the number 2
That's perfectly fine as a special case. By not checking even numbers in the loop, you reduce the number of comparisons you have to do by half.
You just needif (n % 2 == 0)
return n == 2;
after the (n < 2) case.
>>55111763
Why even modulo it?
If you already know 2 is prime, just return true if it's 2.
>>55111797
By handling all even numbers outside of the loop, you can change it tofor (int i = 3; i <= sqrt(n); i += 2) {
if (n % i == 0)
return 0;
}
return 1;
Also a few other notes. It's "<= sqrt", otherwise numbers like 9 will come out as prime.
"n != i" is guaranteed by the loop condition, so is pointless.

I need an algorithm that keeps my period roughly the same depending on the input size of a signal.
How do I do this? Pic related.
Either cos or sin solution. Shouldn't matter.
Preferably in Matlab, that's what I'm trying it in.
I only have experience doing work in kernels and desktop applications, but I've been approached recently with making small websites for people (small as in I can probably get away with making it all static). I muck around with userstyles and scripts, but I've never really developed a formal stack or workflow from scratch.
Do I just go to town with simple hand-made html/css/js files or should I pick up some other stuff? It seems like if I actually want to impress people I ought to be using React, node, etc.

>>55112208
>>55112270
Haha trolled u
>>55112191
multiply x by a number to normalize the period.
For example, if the period is 2, multiply by x by 2. If the period is 5, multiply x by 5. That way the period is always 1.
I have a programming assignment for a small game that allows you to tap cells in a colored grid to make them disappear. I'm having trouble keeping the score. The method for calculating the score is run at the end of the game.
I'm currently calculating score by running through the entire grid and counting all the empty cells. However, this doesn't keep track of all the rows that have been eliminated. Any tips?
How come every time I get stuck and want to ask a question I figure it out immediately after I hit post?
>>55112322

Well, if you're going to interpret it as something English that can be given an initialism, it's the only phrase that makes the most sense. Reading it as "for example" is counter intuitive because the first letter isn't f, and the second letter isn't e.
>It's worth remembering it just like that so you don't do something really stupid and use "For e.g." which reads as "for for example".
"For example given" also sounds retarded. Reading it as "example given," one further expands it out to "the example given is..."

Firstly, Latin doesn't map to English without adding in filler words, it's about as least verbose as you can get (in western languages anyway).
Secondly, why do you need an initialism, are you dyslexic? Not everything needs an initialism to be remembered, especially something this basic.
Besides, just say example in spurdo-speak and you get eggsamble, which starts with "eg". There, I made it memorable even for a dyslexic 4channer.
>one further expands it out to "the example given is..."
You're reading it as example given, but that alone isn't enough for it to make sense, so you have to add in "the" and use 3 words to explain a 2 letter initialism.
"For example" is already grammatically correct, probably because it is the English meaning of e.g.

As software becomes more and more complex, it also becomes more and more fragile. The only exception seems to be the internet, which has only become more reliable as it grows. The reason for this is the internet is inherently redundant - packets will find new routes to their destination if one is knocked out.
Will software devs adopt to this kind of redundancy? For example, rather than saving a variable in only memory (and open yourself up to loss due to computer crashes), software might save it to the local disk, to the cloud, and to memory. When the variable's value needs to be accessed, the program can check memory first, then the disk, then the cloud. If we mind our abstractions, doing this will be as simple as declaring and dereferencing a pointer.

>>55113549
But maybe I don't want to save all my variables on disk? Maybe that would be a huge waste of space?
>>55113549
No, that sounds great.
Instead of simply reading a stack variable from the registers, now you can wait literally forever for a disk read, or better yet, WAIT FOR A TCP PACKET!
>>55113583
Say you have 16gb of memory. You could save everything in memory to a 16gb flash stick for around $5. This is a very cheap operation.
>>55113549
thats already a thing for computers in satellites and whatnot.
>>55113602
You'd only need to do a disk read if the memory was corrupt or was lost somehow, for example after the computer was abruptly power cycled. If you hadn't written to disk, you'd be totally screwed - a slow read is only an improvement from that. Saving to the cloud means you can resume program operation even if the computer you were using was destroyed. Again, you'd read from memory by default, from disk or network in the case of memory failure.
>>55113654
I don't understand why program persistence is such an important issue when the computer running the program has just been destroyed.
If your servers are suddenly destroyed, so will your disks, and you won't be able to suddenly download your execution state back from the CLOUDDD

what is wrong with read() and write()?
yo /g/, I'm making a tool that visually creates data structures of custom types. I currently support lists, queues, stacks, deques, and trees (n-ary by default with a tool pane for enforcing constraints like heap, binary search, etc.) I intend to add priority queues next and possibly graphs after that, but I come to ask: do you feel there are any data structures you would like to see that I am missing?
On the radar: set (would be pretty easy to implement and report collisions based on live hashing) and dictionary/map (might be hard due to the nature of the tool, but I might be able to pull it off)
Apparently I missed something basic when I learned java. How can I just throw an exception without handling it? Everytime I try the compiler complains that it's unhandled.

Exceptions thrown are passed to the thread that called the thing that threw them. You can throw exceptions all day, but EVENTUALLY they're going to get caught by SOMETHING. That something is either your own program, someone else's program, or Java itself. That last one is what you don't want to happen, because the default thing Java does when it catches an exception is ABEND.
Sometimes you throw an exception and you're a retard who didn't realize his code was operating on, say, a button's thread. The button will catch any exception you throw to it, and it will deal with that exception by crashing the environment with no survivors.

No, we're all busy talking on our similar but incompatible systems.
I have a probably simple problem.
I want to do something basically like this in C++:class NodeHolder {

class Node {
public:
int data;
void DoStuff() {
//Insert a new node
Node newNode;
::nodes.push_back(newNode);
}
};
};
So basically I have a bunch of nodes that are contained in the NodeHolder. Sometimes the nodes want to allocate new nodes, and I want them to allocate them by adding them to the parent class's vector of nodes.
So how can I access the parent class? Is there a better way I should be structuring this?

OOP is good for one thing: abstract stuff in very well understood domains. That's why it works for, say, the Java standard library: data structures and algorithms that are thoroughly researched.
IRL, problems are not that well defined, and requirements change.
>>55115674
Can be done without OOP
>>55115741
Of course. But I think that was one of the reasons it got so popular. People saw that it worked well on that stuff, and thought it would work everywhere else.
GUI might be another place where it worked ok. FRP is far better, tho.

So much better, the only thing that used it abandoned it.

I want to make a REST API, probably with flask.
But I don't know what to make it for, what to do with it.
>>55115909
How much programming experience did it take to make this? Want to be at this stage myself in the future.
>>55116029
then you don't really want to make rest api
>>55116029
What kind of post is this? It's like saying "I want to make a GUI but I don't know what the software will be". Then you can't really make the interface for it now can you?

it's basically linear algebra (and a bit of recursion). Reference Image and most models (phong lighting, flatt shading) are from here http://www.cs.cornell.edu/courses/cs4620/2012fa/lectures/35raytracing.pdf

Starting a new intermediate position in an enterprise on Monday, any tips from fellow anons on standing out properly, or should I just keep my damn mouth shut and work?
I'm trying to learn perl and all I can think while going through this is "What the actual fuck"
It seems so damn useful but I can't for the life of me understand the internal logic behind all of these weird choices. Why are there like 20 different ways to write strings and arrays, but only a few unordinary ways to write hashmaps? What is the point of sigils, and why do subroutines mash arguments together as a list?
i'm not hating, it just seems so autistic
>>55115909
Pretty nice
How much do you guys feel you retain after reading a book?
>>55116459
0 percent
>>55114331
constant comments to remind myself so I don't go full retard every time I come back
>>55116459
About enough to feel confident that I can perform in relation to the topic without needing to refer back to the material, but not enough to be able to perform in relation to the topic without needing to refer back to the material.
>>55116459
When reading a reference book, I do multiple readings. The first reading is to get introduced to the language in the book. The next reading reinforces the ideas that I want to extract from the book. The third reading clarifies little details about the subject matter that I'm reading.
from bs4 import BeautifulSoup
import urllib.request as urllib2
import os
url=input('Url of thread:')
headers='Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.107 Safari/537.36'
req=urllib2.Request(url,headers={'User-Agent':headers})
try:
html = urllib2.urlopen(req,timeout=20).read()
soup=BeautifulSoup(html,'html.parser')
print('\n'+soup.html.head.title.text)
except Exception as e:
print('Error',e)
arr=[]
for element in soup.findAll('a'):
if element.get('title') == 'Reply to this post' and element.parent.get('class') == ['postNum', 'desktop']:
arr.append('>>'+element.text)
f=open('out.txt','w+')
for element in arr:
f.write(element+'\n')
f.close
print('\nYour file is labelled out.txt')
now even you can spam threads easily

What's a good resource to learn about formal verification

Wish me luck
>>55112191

>>55116895
GOOD LUCK!! YOU CAN DO IT!
>>55116893
I did a formal program verification paper in University.
The textbook for the paper was "Logic in Computer Science - Modelling and Reasoning about Systems" second edition by Michael Huth and Mark Ryan.
I never actually read it myself, but I assume it contains all of the information about that sort of stuff.
>>55116895
>In statistics, logistic regression, or logit regression, or logit model[1] is a regression model where the dependent variable (DV) is categorical.
Ahh, now I see. Good luck.

And how the fuck are you going to determine whether it's corrupt you stupid fucking retard?
I posted yesterday about wanting to thoroughly learn a new language so I'm not just seen as a web guy. I wanted to do one of the newer languages just because it's more interesting, and after considering Julia, Scala, Rust, Haskell (not new I know), Crystal, Kotlin, and a couple others, I have decided on.........Rust. It seems like the only one out of the newer languages that is for sure going to be at least relevant 10 years from now. I think I'm gonna take someone's suggestion from yesterday and implement coreutils in it for practice.
>>55116962
Thank you friend
>>55116987
It's part of machine learning, it is basically creating a trend line to decide which category an input should go into.
The math pains me because I am no mathematician

>The only exception seems to be the internet, which has only become more reliable as it grows.
The internet is 'reliable' because it's over engineered. Big ISP's would rather build more or bulker routers to handle traffic than come up with an efficient one that handles loads when over ~60-70%.
If they actually didn't over engineer it, we'd have an unstable shitstorm.

Nice counterargument, fuckface.
So /dpt/, I'm trying to become a programmer.
I'm learning Java and Lua first, (Java is required by a computer scinece course I'm taking), and Lua because it's easy.
After learning a few languages, how should I start getting into writing programs and hacking? [spoiler]white-hat[/spoiler]
>>55117391
>learning a programming language
>not writing programs
You can't learn a programming language without writing programs for it
>>55114542
Yes it is. Using modulus ends up chugging at about a million.
>>55117408
I have written some. I wrote a dice-rolling program in java. It just picks a random number between 1-6 when you press "a". I wrote a side-scrolling shooter in Lua, but have since lost the code.
What programs shoould I start writing as practice, per your suggestion?
