In Pony, unary operators always bind stronger than any infix operators: not a == b will be interpreted as (not a) == b instead of not (a == b).

Should I learn C or C++? I'm not sure what I wanna do in the future, but I'm thinking about learning some reverse engineering for fun, and I also want to be able to transition into C# if needed (for work). I already know Python very well, and have touched Golang/Java (in addition to webshit, including JS).
C is just a subset of C++, correct? So why not just learn C++?

currently I have this

devShell = pkgs.mkShell.override

it does make clang as the default compiler and shit, but it still uses /nix/store/<hash>-gcc-10.2.0/include/c++ unfortunately

Practically yes. There are silly edge cases that are different that autists will bitch about but they don't matter in the real world.

If you aren't smart enough to learn C++, you can learn C instead. Otherwise there is no reason.

I made a simple math-game to learn a bit JS. Every time a level is finished basically this function is called which based on player difficulty and level checks calls another function with fixed parameters to create new calculations to solve. My question is how this could be shortened or made better. I switched already from if else to switch cases. I am pretty new to programming so nothing to complicated/abstract please.

There is no such thing as "colored output". c++ only outputs text to a buffer then the terminal reading that buffer may add color or not.

Using strings to represent words is fine. The problem is there is no constraint on the values of those strings. I could create a Pokemon like this:

new Pokemon("myPoke", 1, "not a real sex", "not a real location", false, "not a real type", "also not a real type)

This pokemon is complete nonsense. It's very likely to lead to bugs later because you haven't constrained the values each property of the pokemon can take on. You can fix this by representing sex & type as enums, and by representing catchLocation with a custom Location data type.

3 words: correctness by construction. Try to write programs so that if it compiles then it maintains key invariants.

Most python devs would probably use defaultdict for that pattern, if it was any code worth caring about

You do have some boilerplate as you need to import defaultdict from the standard library:

from collections import defaultdict
dic=defaultdict(int) # could also use a lambda here to initialize a non-zero value if desired

But then this is all you need:

dic[cum] += 1

If I had started 13 years ago, I would have had to nonstop chase the breaking changes with every subpoint version update, that's one of the main reasons everyone stayed with 2 all this time. Other reasons include:
- It's slower
- It's more verbose
- Until recently, it was outstandingly buggy
Did you know that dictionaries in python until 3.5 or so were naive and outrageously low-performance? The kind of stuff that undergrads work out in year 1 as part of their classes was not implemented until that late, because guido is a complete hack.

Stupid question:
Distributed file systems, such as Hadoop split data into blocks of a fixed size, 128MB as default in Hadoop. Now the claim for most distributed data processing is that you should "move the code to the data, not the data to the code". My idea of this is that you run the processing of a block where that block resides in the cluster. But how does that even work? In order for it to work you'd need each block to be sensible for the type of processing you intend to do. In case of a simple word count you'd need to make sure that no word was split when splitting the file into blocks, json files get even trickier, and you'd need to support this for all kinds of data?
I feel like there is a major step I'm missing here. Does anyone know how this works in practice?

I've been using python3 for awhile day to day and generally like being on the up-to-date versions. There are a few tweaks in the standard library I like that let me skip using 3rd party libraries (or my own wrappers). Specifically I'm thinking of urllib.request and subprocess.run. I still prefer requests and my custom subprocess wrappers but if I need a portable script with no dependencies, those functions are far better than what's available in 2.7. And of course unicode blah blah.

Otherwise: you're absolutely right. The move from 2 to 3 was an absolute shitshow in every way and where the only messaging was alternating gay evangelists hyping features I didn't care about and "beatings will continue until morale improves" from the footsoldiers.

I still have some code running on python 2 which I actually didn't realize. It's been passing linter checks in 3.7 for awhile but there's still code in there that doesn't actually run with Python 3 so at some point soon I have to go in and fix it.

I know how to do it, I did it by hand a few times to port utilities because some libraries are dumping support for python 2 in new versions now (which is a huge problem, I have publications with code attached and at this rate, in 5 years, nobody will be able to run it without modifying everything). The guide is not at all comprehensive: new map breaks everything, new string breaks everything, etc. That said I hadn't heard of modernize or futurize, but I was using six and __future__ imports anyway.

not a stupid question anon, good question.
i did a search. remember that you don't program against HDFS directly. instead, you use MapReduce. MapReduce stores "record splits". Apparently, you store records in HDFS. Then, MapReduce is aware of how records are split physically. MapReduce handles consolidating the record into a single data structure, which is what your code executes on.

This happens to every language, and it could be much worse (i.e. Python was dropped after 2.7 for some new language, meaning no one could even port your code or use it for reference).
>I was using six and __future__ imports anyway.
You shouldn't have been using six unless you needed to support Python versions older than 2.7.

That's not a problem if python 2.7 is still maintained because someone can download the python 2.7 interpreter and run the code anyway. This is common even today, while nobody in the field uses matlab or fortran anymore, code in those languages is still sometimes needed from old packages.
Here however, because python 2 and 3 are artificially at odds, upstream makes sure to prevent it from working over time, and downstreams also do the same e.g. in distro package managers.
Additionally, the packages that some code may rely on is eventually going to stop working with python 2 altogether, and old archives of this code will not be available because nobody cares about maintaining at least the last good python 2.7 version of the code.
Additionally modern python 3 versions don't work on windows 7 (there's an artificial check in the installer).

Maybe one day there will be a self-aware Python 3tard who can actually take the dicks out of his mouth long enough to admit the way Python handled the transition to 3 was far less than ideal. The article link doesn't prove your point it proves his, that you need a whole article explaining the hoops you need to jump through (instead of actually spending time solving the problems you picked python to solve in the first place)

I expected them to support it indefinitely as they deployed it as a cornerstone of their service managed by Amazon and not the customer. As as reminder, COBOL, FORTRAN, and Ada are still actively supported. If they expect me to fall for vendor lock-in like lambda, then they better not abandon their shit after 10 years. Never using lambda again, I'll roll my own. What a joke that a trillion dollar company throws up its hands and does a "nuthin' we can do" because they're no longer getting free patches from freetards.

Line splitting makes sense for map reduce jobs. Because it's a pretty trivial task and ridiculously parallel for most parts. I guess things like sparks RDDs need to do something more complex upon creation to be sensible, as you can read files from HDFS directly into RDDs, but I'll find that out for my self. Thanks again!

Maybe to do basic web shit. It heavily depends on your background as well. But as a rule of thumb, don't set these kind of "learn X in Y amount of time" goals. Simply focus on becoming as good of a developer as you can, you are ready for employment when you are ready for employment. Of course you can apply to jobs after 6 months, and if you land one, hey that's great, but the ride is far from over. With a short time frame like 6 months, at best you'll become a web developer who is completely bound to one tech stack, and shits the bed when having to work with new technology.

I have no experience with desktop gui software is it possible/advisable to make something like a visual node editor in pyqt5? I am trying to port some of my ocr scripts and embedded the preprocessing stages as visual boxes you can see (to modify, skip etc.).
Can that be easily done with pyqt5 widgets or should I just use opengl for that? It would somehow like this http://playground.tensorflow.org/

What do you mean different lambdas? Lambda is syntax sugar for single method interface. So you just create more interfaces and create methods that accept those interfaces

void foo(OneArgumentInterface);
void foo(TwoAgumentInterface);
void foo(ThreeArgumentInterface);

If they're the same type of argument, just use vararg.

Serious question guys - I'm building an application in flutter and making some API requests. Every tut I look up has some pajeet making 9 different error handling classes to cover 55 slightly different things. This all seems retarded.

Is there any reason at all, why I cannot place a status.dart file like

enum Status {
SUCCESS
FAILURE
CONNECTIVITY_ERR
TIMEOUT
}

and just leverage these in displaying any error handling to the user on conditionals? Am I missing something here, or is proper revolting against pajeet pay-per-line stupidity?

You need to either fuck up big or be a complete retard to be laid off.

Well I made my own changes: using a boolean intead of a break to end the loop, and having better looking output.

You might want to know slightly more than "there was an error" if you ever have to debug something. Enums are dirt cheap so there really is no reason to hold back.

What am I missing to upload an image?
Text works, but I've never been able to get an image uploaded here.

Sounds fair - so your issue wouldn't be the use of the enum, so much as the quality of the description. I think dart allows simple methods for enums... In this case, more than sufficient then.

So I will post it plain bc no one respond
public static void main(String[] args) throws Exception {
if (args.length != 3) {
System.out.println(
"Usage: java MergeFiles file1 file2 mergedFile");
System.exit(1);

}
File file1 = new File(args[0]);
if (!file1.exists()) {
System.out.println("file1 " + args[0] + " does not exist!");
System.exit(1);
}
File file2 = new File(args[1]);
if (!file2.exists()) {
System.out.println("file2 " + args[1] + "does not exist!");
System.exit(2);
}
// Check if target file exists
File targetFile = new File(args[2]);
if (targetFile.exists()) {
System.out.println("Target file " + args[2] + " already exists");
System.exit(3);
}

try (
Scanner input1 = new Scanner(file1);
Scanner input2 = new Scanner(file2);
PrintWriter output = new PrintWriter(targetFile);) {
while (input1.hasNext() && input2.hasNext()) {
String h1 = input1.nextLine();
String h2 = input2.nextLine();
ArrayList<String> list = new ArrayList<String>();
list.add(h1 + " " + h2);
for (String c : list) {
System.out.println(c);
}

}
}

}
}
I want to print the result using the last for loop with the elimination of duplicates and in a sorted (alphabetical) order, what to do from here? I'm completely stuck.
