What are you working on, /g/?
Really /g/, what is OOP exactly and why is it so good?
[spoiler]
There are thousands of definitions, all of them are bullshit. And you can't defend it without using the True Scotsman fallacy that this mess enables. It's just a costly mirage, we should move on to Concurrency Oriented Programming.
[/spoiler]
So far the only reason you guys gave for why Java is bad is all meme reasons. Verbosity is not a real argument either is reference equality or serialization

>>53733370
fuck off retard
see

uhh...
CGo pointer rules added in 1.6 are really confusing at times.
- return C.GoBytes(unsafe.Pointer(&img.data), img.size), nil
+ return (*[1 << 30]byte)(unsafe.Pointer(img.data))[:img.size:img.size],nil
That'll fix it for now.
I was in a Go datastructure that the C code kept around and then calling C.GoBytes on data that was allocated by gc.
Go pointer to Go pointer.

>>53733497
The whole point of OOP is to not repeat things.
>>53733497
It's easy: just write a factory
>>53733516
You know there's functions and polymorphism for that already right?
btw: OOP "polymorphism" is not true polymorphism
>>53733516
Avoiding unnecessary repetition is the goal of PROGRAMMING, not of OOP. Many other paradigms have much stronger solutions.
>>53733519
>write a factory
Repetition.
>>53733458
When will you learn? Multi paradigm doesn't work.
>>53733531
>OOP "polymorphism" is not true polymorphism
Can you expand on this?
Examples with no object-oriented characteristics would be appreciated.
>>53733394
>>53733412
This. There are only two important parts.
First: typename_methodname(instance, ...) turns into instance.methodname(...)
Second: easy polymorphism through inheritance without fiddling around with function pointers.
That's all there is to it but then your university professor says you should use polymorphism and inheritance everywhere because it magically solves all your problems when in reality you should only use it when you actually need it.

I think he means that OOP polymorphism is just a corner case of polymorphism
I.e. oop polymorphism is subtypying via inheritance
Polymorphism includes:
Parametric polymorphism (templates, generics)
Ad hoc polymorphism (overloading, overload sets)
Subtype polymorphism (inheritance, discriminated union, implicit casting)
Lots of "OOP languages" use the others, but these aren't OOP features

You just get to dispatch based on one argument, arbitrarily promoted as the "receiver". It has its uses, but in a statically typed environment, you can use much more typing information that that. take the eternal Haskell example:mySum :: Num a => [a] -> a
mySum = foldl (+) 0
Here, Haskell selects one of the many existing implementations of +, based on the type of the list. It does this once at compile time, instead of doing it as much times as there are elements on the list, and throwing an exception at the 999th elements on 1000 because it is not satisfied with the other term of the addition for some reason.
>>53733674
Its an autohotkey script for calling user32.dll, with the basic syntax and the values necessary to do this so that he can port it to whatever fucking language he's writing his malware in.
Program's GUI windows on Windows operating system have a control bar at the top, known as the system menu. a system DLL (user32.dll) exists that can manipulate any window's system menu by targeting its identifying hwnd and then you issue the call with the RemoveMenu function to adjust its menu which updates the UI provided by the OS.
Be aware that adjusting menu's dynamically is STRONGLY DISCOURAGED on msdn as it looks unsettling to the user, no one will want to use your piece of shit software if it does this, just saying.

>>53733531
Polymorphism is an extremely generic term. Different groups of people use the same word to refer to different things. There is no such thing as "true polymorphism".
Arguing about "true polymorphism" is like a birdwatcher and a construction worker arguing about whether a "true crane" refers to a bird or a machine. Both are equally valid.
I want to an anki clone that focus on learning japanese and japanese vocabulary.
how do I make in java (it's for android) a class that contains let's say 500 strings and each string contains also information like being in the top 10, 20, 50, 100, 500, cathegories (as to easily make top 10 and other sublists) plus also having a score based on how many times you guessed right it and a time float indicating the time it should come back for review.
Also I should be able to have for each entry a certain ID so I can randomize the order in which they appear.
Also information over each word about it's grammatical function (noun, verb, adjective, adverb, conjunction, etc).
Also a bunch of tags like office, family names, places, etc.
All this information for making diferent vocabulary list like top 10 adverbs, top 50 verbs and list like food and so on.

explain to a retard what is a SQLite database.
>>53733849
SQLite (/ˌɛskjuːɛlˈlaJt/[3] or /ˈsiːkwəl.laJt/[4]) is a relational database management system contained in a C programming library. In contrast to many other database management systems, SQLite is not a client–server database engine. Rather, it is embedded into the end program.
SQLite is ACID-compliant and implements most of the SQL standard, using a dynamically and weakly typed SQL syntax that does not guarantee the domain integrity.[5]
SQLite is a popular choice as embedded database software for local/client storage in application software such as web browsers. It is arguably the most widely deployed database engine, as it is used today by several widespread browsers, operating systems, and embedded systems, among others.[6] SQLite has bindings to many programming languages.
>>53733839

>>53733895
No it's a database contained in a single file.
>>53733901
It's a magic box holding your data. Seriously, if you've never used a database, don't start that project. Stick with fizzbuzz tier challenges.
Im working in a new compression algorithm that can theorically compress 80% most of the files without data loss.
Pros: Theorically can compress 1GB files to 50MB
Cons: Is slow, almost 3 minutes to compress files bigger than 10 MB, and the times exponencially grows.
All praise the Richard Super Conpression Algorithm (RSCA)

Porting a project to js. I've been trying different methods of rendering a lot of shapes to the screen and I've settled on WebGl after SVG + Bonsai.js proved too slow.
Js has a lot of potential - I can see that, but is there any IDE/editor plugin that will catch simple errors as I type?
I think that one of the reasons why Java is so popular is that eclipses live syntax checking is awesome. I don't see why this couldn't be done for other languages as well because it's one of the most powerful productivity tools around.
Eclipse Parallel edition + Fortran gives red underline syntax errors when you build but I don't see why this couldn't be done live.
>>53733929
Ohh I see so an entire database in one file where you can manipulate data locally on your device such as a phone?

You should learn SQL first
Someone help me with sql
Lets say you have 2 tables with 1 row one (1,2,1,2) and second (2,1,2,1) when i do a normal inner join :select * from table1,table2 where table1.row=table2.row
Now if i type it like this i get 22112211 and if i switch table1 with table2 i get 11221122 why is this?
how the fk joins work?
I've been told that only the common members from both tables are shown according to that condition but why instead of 4 members my resulted table has 8?
no matter what your opinion is about java, you're retarded if you don't think C# is worse than java.
C# is literally a cargo-cult clone of java with massive feature-creep due to a load of dunning-kruger pythonesque "features" tacked onto it that you aren't even supposed to use
>many of the disadvantages of java
>many of the disadvantages of C++
>few of the advantages of java

java is good for its simplicity. if you don't need simplicity you may as well use C++ instead. the "low level features" in C# still give you shit performance.

can't be done for JavaScript because it's dynamically typed (no type errors until the code is run)
I mean, syntax errors are still possible to catch, but it will never catch all the errors your IDE can catch for Java. if you want something that can, I recommend trying out TypeScript in Visual Studio Code

Yeah I figured that Js and C++ would be a little too complex but surely C/Fortran and one or two other languages are simple enough to allow live linting and catching 99% of syntax bugs without having to run it and see the compiler output.

Assuming all of your devices will be 'calling home' and retrieving data from a centralized location, you could stand up a server(your OS/distro of choice) with a MySQL or PostgreSQL installation for free (other than hardware/hosting costs).
A relational database would likely be the best way to get the structure you're describing, because the connections and relation between objects is meaningful.
This would force the application to be online-only, but you could also implement a caching system locally on the device. As far as storing this information directly on an Android device, I am not familiar with best practices for that.
As for retrieving the data, there are numerous Java libraries for sending and retrieving data from most database servers.
For example, in C#, you could do something like this:SqlConnection thisConnection = new SqlConnection(@"Data Source=localhost;
Initial Catalog=default;
Persist Security Info=True;
User ID=user;
Password=B1GT1tti3z");
thisConnection.Open();
string Get_Data =
@"SELECT *
FROM tablename";
SqlCommand cmd = thisConnection.CreateCommand();
cmd.CommandText = Get_Data;
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
sda.Fill(dt);
var ayy = dt.AsEnumerable().ToList();
foreach (var number in ayy)
{
WriteLine(number.ItemArray[0]);
}

>Do you rely on applications to do that type of work for you, or do you do that by hand?
That's usually done in the initial setup of all of the data definitions and proposed table design. When you're doing this, you generally work hand-in-hand with the software/application designers.
You start defining things, such as
>What is a computer?
Well, each computer has a primary key and some basic statistics about the computer.
>Well, a computer could have any number of disk drives
Cool, let's have a table for disk drives and the drives have a key pointing to the computer they belong to.
Etc.
>Also have you ever had to normalize stuff beyond BCNF?
Generally, no. The use-cases for normalization beyond your basic 3NF are limited and usually the uses are a bit contrived.
However, my opinion is that every database SHOULD be normalized AT LEAST to 3NF, because you can always denormalize with views later if needed. There are some use-cases where denormalized tables are 'fine', but generally they cause more harm than the problems they solve.

Sorry anon, everything is still on paper.
Its a midly serious investigation, and we dont want to code anything untill everybody on the team knows exactly how it works forward and backwards.
All our test are by merely calculations, and in theory, we can compress any file by 80%.
Other pros: No need for dictionary. Theorically you can compress a compressed file multiple times and recuce its size again.
Other cons: The compression level is based in procesor architecture, so you will cant decompress files that where compressed in 64 bits OS, to a 32 bits OS. (But we expect to fix this oin the future).
If everything goes right, we can (and will) release an alpha version of the compressor and decompressor for windows in abouth 3 months. So wait for it dear anon.

>>53735228
Mate it's easy
You store the file in Pi, then store the index in Pi, etc until you have a 1 bit number
>>53735164
So, eventually everything can be compressed to zero bytes?
Is there a website that gives you problems to solve with code? I really want to get into coding, friends.

perhaps I don't, but i sure as fuck understand it a lot more than you.
>>53735296
He's on about looking up a sequence of bits in the binary representation of pi that are the file that has been 'compressed'. For this, you'd need a start index and a length. This should work, if every possible sequence of bits eventually turns up in pi, but it won't be able to reduce the size of every possible file.
>>53735341
It won't work m8. Lossless compressions are bijective functions. They can't make everything smaller.
>>53735356
I presumed that's what he meant, but the size of the start index is most likely going to be much much larger than the size of of number being looked up. Probably astronomically larger.
>>53735341

>>53735379

He means Java programmers. Java programmers generally only know Java, so they defend it as if they are superior to other programmers who have different preferences, as if most programmers also only know one language and simply have never tried Java to know how great it is. This is the mind frame of the sort of person who says "Java master race". I find 9/10 of these people only know Java or maybe one or two other terrible languages like PHP or JavaScript.

memsort, not memesort.
It's a genius sorting algorithm I invented that is similar to sleep sort, but instead of using the value as a parameter to a sleep function, the value is used as an index into an array, where the value in the array at that index is incremented.
You then loop through the array and for each non-zero element, you append the index of that value into the output array and then decrement the value, repeat until 0.
I had an example implementation but I threw it away, it's easy enough to re-implement anyway.
I haven't compared it to other algorithms, but I imagine it being quite efficient in certain situations.

Now it's pretty clear it will cost at least 6 times more than he originally claimed he could build it for, and will keep out pretty much no one.

This is why Java is the number one programming language
Java (esp. at its time) had some serious advantages over other languages, which is why it won out:
It has a C-like syntax so it was easier to switch over.
It has a pretty huge standard library bundled with the core language -> no need to get into installing dependent libraries
It has Sun Microsystems to push for its success
It has Garbage collection which is a big win because manual memory management can be a huge pain in complex programs.
It prevents a whole heap of common bugs (like reading/writing/executing data you are not supposed to read/write/execute)
Now there is a huge ecosystem around java, which is why it is so hard to replace with any other language.

$26 billion for raw materials and labour at a minimum. It would also achieve pretty much nothing.
I like trumps tax plan and healthcare plan.
>good businessman
Is he? He's only actually worth 10% of what he's claimed. He sued some guy who wrote a book about this and lost, and then lost 2 appeals. During the appeal he claimed how much he is worth varies depending on "how he feels on the day". I understand if he put the money he inherited on a tracker index instead of running his own business, he'd be worth more. So, not really a great business man by that metric.
>best people to run the country
I like that he would probably negotiate better trade deals, but I don't know about anything else...

Of course there will be other similar classes, but the container name shouldn't be exactly the same as the most common one with only the first letter decapitalised.

>you're retarded
Why am I retarded? I've just said a bunch of points that you clearly agree with, since you're not dismissing them. Is there some reason you know I'm wrong but are afraid to tell me? You can tell me anon. I won't bite : 3.

>Of course there will be other similar classes, but the container name shouldn't be exactly the same as the most common one with only the first letter decapitalised.
I totally agree. It's just named like that because I couldn't come up with a better name for it.
>Given that they call it "std" and not "standard", I would suggest calling the container "str" and not "string".
The first namespace is always the name of the library / executable. And since this library comes with a very generic name "libstd" the first namespace got "std". So I need to come up with a better replacement for "string" namespace.

What has that got to do with anything? If people want to get past a wall they'll try it, no matter who runs it.
>no cameras, UAVs
Are you saying Trump will make an invincible wall that no one will be able to get past?
Get real.
>>53736772
I wonder why people ever built walls at all. We've had ladders and ropes for as long as we've had walls. I guess they're all just idiots.
>>53736806
Sometimes they work. Trumps one, as he proposes it won't for the reasons I mentioned before.
>>53736852
You know, the reasons that have applied to every wall ever, like ladders/rope, cost, the fact that a wall would never slow anyone down
>>53736868
The same type of walls work just fine for the Jews in Israel
>>53736590
Seems pretty damning to me.
>>53736868
yes. Others have smaller borders and are willing to pay a LOT more. If Trump really wants the wall, he could pay for a way more expensive one. But I doubt anyone will want to pay for it.
New thread: >>53736903
it's like you've forgotten that obama has spent trillions on dumb shit like bailing out the banks
$10-20 billion on a wall is chump change

this
>>53736936
that was money printed by the Fed and loaned by the Fed, and is owed back to the Fed. It was never in the treasury. The US national debt is high enough already, if they borrow a lot more for "just because we can" projects, then it won't be long before they default. And this time there isn't a gold standard for the GOP to "temporarily suspend" when a run begins.
