Think about this, or Fahrenheit451, or anything sci-fi novel really: this is what we are heading towards if we go for a pure free-market society with no evil gov't at all. We become more and more reliant on whatever big corporation can provide as bread-and-circus all-in-one pack, to the point where the free market destroys itself and competition is only a faint dream. This is what you would probably term a communist shithole, yet it is the probable outcome of our current system. Citizens can only remain reasonably independent if they control at least part of the services they use, and this includes seeds (Monsanto owns your crops, did you even know?) and software, which put RMS, indeed a leftist but not an authoritarian one, on the side of reason.

I'm learning node.js at the moment
>inb4 web peasant
I've only ever done front-end work (AJAX and API interactions, etc). This is my first foray into back-end programming. What I don't get is this whole "server" stuff. "You can make a server in node, and it will serve up responses to user requests"! What is special about this? I've used FTP to throw html pages onto servers, and I've obviously never had to program any of that for it to work.
So, what is it that backend languages do, exactly? I know they interact with databases, but I have no idea what value that really holds. The idea of them serving up html in response to user requests doesn't strike me as particularly interesting either, considering when you buy a server that stuff is all pre-installed.
Are C# and Xamarin good to learn?

well, I compiled it on windows, and on linux using mingw with the same outcome - it just did that "program stopped working", there was no error message, and the program works fine on linux (I don't usually use windows)

I want to love Rust but they make it really hard for me.
>>53881364
and you don't get any compiler warnings or anything? are you using libraries outside of the standard library?
>>53881364
does helloworld work with the mingw setup? I tend to think that your mingw install is fecked for some obscure reason. Mingw is usually quite robust AFAIK. Is it any C program or one specific C program and not the others? Narrow you issue down - it's exciting when it doesn't work!

Look at your error list in Visual Studio, and the red underline under that part.

What a silly post.
Not saying you can't make money with Java, but there are plenty of lucrative opportunities with other languages.
>>53881954
I make money with python, so its the best programming language.
>>53881954
Not with Happy BALLS you won't
Java is clearly superior to every other language even the web languages like HTML and CSS
Sup it's me(>>53879322 (You)) again
I tried so far doing this with the WebBrowser for the learning experience.
I've managed to connect, I know the page is loaded because I'm executing functions from a WebBrowserDocumentCompletedEvent, and I can get some of the info.
I tried:public HtmlElement[] GetElementList(WebBrowser browser, string tagName, string className)
{
var elementList = new List<HtmlElement>();
var elements = browser.Document.GetElementsByTagName(tagName);
foreach(HtmlElement element in elements)
{
if(element.GetAttribute("className") == className)
{
elementList.Add(element);
}
}
return elementList.ToArray();
//then parsing to List<HtmlElement>
}
This worked on a simple Html page, without scripts and css.
But when I try to load a List<HtmlElement> from an actual site I get a couple of javascript errors, and then the specific elements are not loading into the list - it's empty.
I can get the whole text with tags(browser.DocumentText), but then I can't make a list of the element's content like I want to.
I can get all the inner text in the inside the body(browser.Document.Body.InnerText), but I get all inner text EXCEPT the elements I need.
Questions:
1) Is the site blocking me from viewing the elements I am looking for, or is the WebBrowser just shitty as described?
2) If I am getting blocked, Is there a way of getting around it, or should I approach it in another way?
3) If I do need to get the info from a string, does anyone has advice on what LINQ can find and each string that is between two other strings that I specify?
4) What's the usual approach to getting info from within tags, for displaying, for example, all messages on a fb wall, or all blog text posts in a winform?
TL;DR can't load needed elements from HtmlDocument, although other do load.

How about you fail to hear my DICK, geek.
my prof says in producer/consumer you want to have mutexes on the outside, and 2 semaphores full and empty. and in producer, you wait mutex, wait empty, post empty, and post mutex. is that right? i thought you would wait empty, wait mutex, post mutex, post full

>>53882037
As a guy who has done professional web development before I could help you but
TLDR
>>53882142
Your prof is wrong: mutex-outside blocks, it's obvious!
Look it up in Tanenbaum's or here: https://en.wikipedia.org/wiki/Producer%E2%80%93consumer_problem shows the mutex-inside version for a good reason. The critical section consists only of modifying the actual buffer, not waiting on semaphores: those semaphores can protect themselves from race conditions thank you very much.
Maybe it was just to see who in the class was actually paying attention? :^)

1: could be that the site uses javascript to generate elements that isn't supported by the Dispatcher/ScriptObject
2: change your user-agent (subclass WebBrowser, override the headers in the BeforeNavigate method), site won't know you're not firefox (or whatever)
3: could use regex for this, but >regex >html
4: filter until you get the tags you want, then get the InnerText or InnerHtml to get the data from inside the tag. and/or GetAttribute
or use something that supports xpath or css selectors.
http get page (httpclient in .net 4.6, webclient in older .nets), feed it into parser, get elements with selectors.

Is an OOP approach really "right" for concurrent designs? The more I try to optimize my concurrency the more old objects must be refactored, sometimes to the point of abandoning the object. I'm constantly running into race conditions and needing to check and think about every little function I write.
Am I just doing it wrong? It's getting so frustrating.

>>53884753
JavaFX and Swing etc are good if you want a cross platform UI. But those are libraries, they don't make the language itself more portable.
Also JavaFX and Swing look like fucking garbage, and Java doesn't have any native GUI bindings. You can easily do first class UI with C# for any platform without it looking like it was made by a prajeet.

Yeah, there's a test that costs $200 or some shit to do, and it's just multiple choice questions about java. You just need to learn the book well enough. The test is on oracles website.
Alternatively you can just build a portfolio of software that you made relevant to the job you want. Database shit, web shit, whatever and that can often be enough. This will take longer, but you can pick from a lot more jobs and many are probably going to be more fun.

>I don't know the difference between half of these jobs
You'll just have to start researching.
Ask here maybe about enterprise jobs and what they are like. I don't know much about except they are easy and pay well, but potentially boring.
You can be a mobile developer too, and learn android and iOS development. This doesn't pay as well, but might be fun.
Web development pays loads. Just learn a popular set of technologies that sound fun to you. One you have a portfolio, apply for jobs. Web dev is easy, but often frustrating and can pay very well. Lots of work here. Maybe ask about this in /wdg/
Those are the main jobs you can get easy.

The whole point of Java is that it's not just a portable core language but its own complete platform. 1st party libraries like Swing are part of that.

Most people are just too dumb to set the SystemLookAndFeel.
Plus it's far from the only cross-platform GUI toolkit for Java.

And that's what i despise the most about it. It's the lowest common denominator on each platform. C# is the opposite.
It's great for making enterprise shovelware, but not for making anything actually pleasant to use.
Regardless, we're talking about portability of the language, not the entire platform.

I'd never claim otherwise.

Conceptually OOP has nothing to do with concurrency, but in practice, a lot of languages are designed for methods to mutate objects rather than return an updated copy. The latter approach, favouring immutability and only permitting mutability when you can ensure you're mutating through a unique reference, is what's important to concurrency.

Honestly I find C# programmers much brighter. Most Java programmers learned Java because they had to in college and work in braindead enterprise jobs. People who learned C# had to actually learn about it and decide it was useful to them and learn it. here's less of them, but the are a much sharper bunch in my experience. Not all are smart, but more are than Java programmers.
With C# on mobile you can easily make high quaity apps because the native API bindings are provided:

Nothing like this is made in Java.
>>53885098
It's the language semantics, and specifically, the type system. The == operator is basically completely unusable, and all languages that compile to JavaScript don't use it.
The syntax is alright, however.
>>53885047
You could. The alternative is having your customers upgrade to an OS written this millennium.

Dynamically typed, weakly typed, broken "this" scoping, modules are kind of hacked in, more verbose than other langugaes.

>>53885047
When has mono ever run software, that targets the latest .net version, well?
>>53885142
What do you mean == is unusable? I love the way it works. It's perfect if I want to compare int 69 to string "69" and have them be the same. Or, the opposite, I want 69 === "69" to be false. Maybe you mean something different though?
>>53885168

{} + [];
>>53885040
no point posting code for no reason. if you're asking for critique, or help, or just showing off then sure
>>53885208
dynamically typed means that there's no compile-time/ahead-of-time type checking, where the compiler/interpreter makes sure that all functions are called with only the right values, all method actually belong to the objects they're called on, etc.
weakly typed means that there's little or no mechanism to stop the programmer from accidentally using the wrong types of variables in a certain place (so it's a runtime issue on top of the compile-time issue) you're basically ALLOWED to call nonexistant methods or call functions with too few/too many arguments and nothing tells you that something's gone wrong
>>53885188
It's not even an equivalence relation."" == "0" // false
"0" == 0 // true
"" == 0 // true

Right, that's what === is for, when you care about type.
>>53885327

>>53885209
ISWIM is definitely related to CPL, but CPL is statically typed and ISWIM is commonly believed to be dynamically typed.
>Nearly all the linguistic features, such as where and while and and and recursive, that Peter Landin has been talking about are incorporated as an integral part of a programming language being developed at Cambridge and London called CPL.

Only jelly Javafags hate C#, as their committee-designed language evolves much slower than C#. For example, next version of C# has pattern matching and syntax for Python-like tuples while the last innovation in Java was adding fucking lambdas at last.
>>53885327
Yes, except that... Wait no. The semantics of == are nonsensical anyway. You do care about type since "0" as a string is different from "" unlike 0 as a number.
>>53885210
I was hoping for critique, or, if I did well, compliments. Unless I share it, I'm the only one who sees my code, so it's nice when other people look at it and tell me how I'm doing. I see where the confusion is though.

XP came out in 2001. More correct would be to say in the past decade.

The concern given was about support, not performance. Mono will support .NET on platforms not supported (yet) by Microsoft's Core CLR, including ISAs that Microsoft will never support (although people are now perfectly free to make a port of the Core CLR to POWER or MIPS). Because Mono exists, .NET can be considered relatively portable.
But strictly speaking, if you want good performance, you should probably use the Core CLR. You should also be using an operating system that isn't complete shit. Do you need to support really old hardware? Linux will probably do a better job at that, and you can, in fact, run the Core CLR on Linux.
>>53885188
A string and a number are so completely different that they should not under any circumstances be considered equal to each other.
That said, even if you accept that disparate types are allowed to be considered "equal", you should at least consider the possibility that equality is a relation that is reflexive, symmetric, and transitive. The == operator in JavaScript is not transitive. If you don't have any formal CS education, that means that a == b and b == c does not imply that a == c, which is pretty fucking illogical. Nonetheless, consider this JavaScript:> "0" == 0
true
> 0 == ""
true
> "0" == ""
false
>>53885378
C# will never compete with F# in anything but performance (where F# is horrific)
>>53885381
Well, an example of when not comparing types is nice is when I have to numbers that need to be compared, and one comes from a string inside of an array, and another comes from some other integer, and all I want to know is if both of them are the number I'm looking for. Otherwise, I would need to either first convert the int to a string or vice versa if I wanted to compare them with the === operator
>>53885209
To be fair that's not exactly a syntax issue, unless you mean the use of + for that operation in the first place and not the non-commutativity of that particular + semantics.

We are talking about Microsoft here. I wouldn't put it past them.
I'm doing Project Euler in C#, and I'm just keeping each problem as its own class for cleanliness sake.
Is there some way that I can progamatically generate a switch to choose what problem I want to run? They all have only one static public method titled "Run()", and while it would be relatively trivial to just copy+paste a case every time I add a new problem I think it'd be cool to have it taken care of automagically.
A point in the right direction would be delightful
>>53885522
It could have taken a year to squash bugs. But i recall XP being pretty flakey when it first came out. Maybe that was just drivers tho..
>>53885534
Be more specific
Code for example "cases" would help
>>53885555
nice quads
>>53885576
It's literally every problem is its own class file.
Euler problem #1?public static Problem_1
{
public static void Run()
{
//Insert Code Here
}
}
Repeat for all problems. They're all public, all static, and all share the same entry-point for the problem via a method titled Run()
So in the actual entry point for the whole project solution (Main(string[] args)) I could pretty easily just put in a switch case asking for a problem number and then have something likeswitch(input)
{
case 1:
Problem_1.Run();
break;
case 2:
Problem_2.Run();
break;
//Etc etc
}
>>53885555
Nice. Very impressive.
>>53885425
>Otherwise, I would need to either first convert the int to a string or vice versa
^definitive proof that you don't understand what's going on behind the scenes: the same number can have a lot of different strings parse to it. If you convert the int operand into a string, you will only have one of the many possible printed representations of that number match, whereas if you parse the string, it'll widen the accepted range in comparison. This is why this kind of stuff should be fucking explicit: it's not just boilerplate, it has a nontrivial meaning godammit!

> put references of all the items into a list
That still presents the same problem as using a switch case though, albeit much more elegantly.
I'm hoping there's some sort of way to call out to a given class at runtime without having to explicitly reference them at compile.
