I feel like I'm not even programming anymore.

90% of the time, I'm just using a library and wiring it to an existing codebase to get some other functionality out of it.

It's not like I don't like being able to do it, but at the end of the day I feel like I'm just putting legos together with prebuilt engines and showing it to my boss saying "ta dah" and everyone claps even though it's easy as hell.

There's tons of languages that have this feature.
Many of those don't define the order of expression evaluation for two reasons:
- it might be preferable on the target hardware to not start with the first one
- It gives more options to optimize
Of course meme languages have a strict definition which parameters are evaluated in which order, they don't care about practicality or performance.

Technically his block works because he's returning the value that was originally input by the user, so nothing outrageous is being caught. He's got that list index

days[x]

going on in there but it doesn't mean anything since he didn't assign it to x or another variable to be returned.

>>59048513
It shouldn't be specific to either version of Python since it's a pretty universal way to directly access items in a list. Check your whitespace/type it out again. Try assigning the results of

weekDay()

to a variable like:

result = weekday(input("Input day number: "))
print(result)

Pretty babby-tier stuff. Some awkward wording in your writeup, too. The "growth rate" section doesn't really make sense, as you're literally just taking a single measurement from one year to the next. You'd typically want to sample more years and get the average growth-per-year for a more meaningful comparison.

At the end of the day, the whole thing is as simple as spinning up a database anywhere you want and running a few lines of code and it's done. Not sure why you've given a complete writeup of this.

Are you fucking blind?

>>59048483
The problem is that input returns a string, not a int, even if you input a number. Numbers can be interpreted as a string or int, so in this case you would have to cast the string to a int using int(). So you would either do print(weekDay(int(input("Input day number:")))) or just
return days[int(x)]

a year-to-year comparison can give you indications about years with lower rainfall.

The issue is not converting from excel to MySQL, the issue is that the tables are horribly formatted. There are columns spanning multiple years which should be condensed into 1 column with 20 records associated. I need to transpose that data, but I also need to slice up the spreadsheet into smaller tables. Height data and foliage density data are in the same spreadsheet but should be in two separate tables joined by the tree ID as the primary key.

The issue is not converting A spreadsheet to RDBMS: the issue is creating a tool so that retards can do it; I'm learning jframe/swing so I can make a tool so that future undergrads can be put to work updating databases and you don't need a programmer every time you need to do this. Transposing an array and cutting up a CSV file is easy, but I'm working on the UI shit too. I don't get why you seem to be so intent on shitting on other people's work?

I'm not shitting on your work. It's not bad work at all. I simply didn't want you to think that someone in the industry would look at this and be particularly impressed, which appears to be the intent of this article.

This is the kind of stuff I do routinely, and I'm certainly not one of these "l337 h4x0r C/Assembly programmers" you see in here; I use high-level languages for projects like this on a regular basis.

What you're describing is one of the first projects done by undergrads where I went to school; creating a database, populating it with existing data, and making a GUI-based application either web-based or desktop-based for users to put future data directly into the database or view the information in meaningful ways.

It's a good project, and - when completed fully and correctly - shows a solid understanding of how applications should work. However, I feel like you could take it a step further and demonstrate at the beginning of the article how you turned manual drudgery into new hotness and happy users, and then explain what you did to accomplish that.

Flash your tits, and then explain how you used to be a man and there was surgery involved. Metaphorically speaking.

Sorry pal, I also have to agree with >>59048834 . He's not a douchebag for stating what the reality is. One of my first non-code example/hackerrank garbage projects was pretty similar to what the anon is talking about; create a DB, populate it, and then make a desktop program with GUI that queries said DB and displays results based on user input. Your project needs CONTEXT applied to it, which is apparently not as common of a skill as I thought after leaving with my undergrad (not STEM).

>I feel like you could take it a step further and demonstrate at the beginning of the article how you turned manual drudgery into new hotness and happy users, and then explain what you did to accomplish that.
This is pretty much why he's taken the position he has. It's great to record it if you actually go the whole way and show how you turned minutes of navigating a mountain of miserable sheets into an application that performs that task in seconds instead of writing a page that's pretty much "man, life is so much easier when you don't put years of data into Excel spreadsheets!" That kind of stuff is what other people and employers want to see.

>>59049039
No, it's not that he criticized it; it's that he criticized it while ALSO telling me how it's something that HE does all the time and how nobody would be impressed about it. It just seems like he's got a weak ego that constantly needs to compliment itself by putting other people down. I never asked him what he did for a living; I never asked him if the project I was working on was a huge project. HE decided that it would be best to tell me about how great HE is and how I'M not.

The project is not a database entry system, it's a system for converting Spreadsheets into RDBMS format, slicing up CSV files, transposing poorly formatted tables, and then inserting them into the database. It's not a 1:1 entry system, but converting old data into new data.

I just don't get the point of the feedback. Here's what he said:

>Pretty babby-tier stuff

How is that necessary?

>Some awkward wording in your writeup, too

Okay, sure, I'm not an english major so that's fine

>he "growth rate" section doesn't really make sense, as you're literally just taking a single measurement from one year to the next.

I explained that year-to-year growth can indicate rainfall, or vice-versa

>At the end of the day, the whole thing is as simple as spinning up a database anywhere you want and running a few lines of code and it's done. Not sure why you've given a complete writeup of this.

This isn't right. It's not a few lines of code; it's an application so that other undergrads can use it without being a programmer. I wrote about this in the post, that writing custom scripts and queries for every spreadsheet may be less code but isn't good for non-programmers.

So what I got from his response was "You're a baby" right off the bat and "I didn't read the post".

It's a useless post. It offers nothing other than to make himself feel better by reassuring himself that he's better than someone else.

>>59049171
wait maybe you need another language

>>59049122

Exactly.
x is unbounded, therefore "tending towards infinity" - unlike what anon said before.


I also like how he says:
>In neither of the above cases to (sic!) we talk about limits or "tending to infinity"

Mr. Lebesgue would like to have a word anon.

>This is the kind of stuff I do routinely

Oh, ok I get it: YOU'RE awesome because you do this all the time. "babby-tier". Stuff you'd do in an afternoon right? I never asked for your life story dude.

>What you're describing is one of the first projects done by undergrads where I went to school; creating a database, populating it with existing data, and making a GUI-based application either web-based or desktop-based for users to put future data directly into the database or view the information in meaningful ways.

What you're describing is not what I wrote about, so I don't think you read the post

>It's a good project, and - when completed fully and correctly - shows a solid understanding of how applications should work.

This is so fucking condescending. It's like "your work is good! But don't think that it means you're good or anything; this is beginner's work, kid". Fuck you, I've been programming since I was 12 douchebag

>However, I feel like you could take it a step further and demonstrate at the beginning of the article how you turned manual drudgery into new hotness and happy users, and then explain what you did to accomplish that.

You got this all wrong.

Success is the result of your experience, experience is the result of your mistakes.

You just learned why it's a good idea to either define the aary length at ONE point in your code or use something like "for (i = 0; i< arr.length(); i++)" or just use forEach.

Congratulations, you're one step closer to being a good porgrammer. Just learn from your mistakes, that's all there is to it.

I'm having a difficult time with exercise problems in this book I'm reading. I'm only on page 60 of the book and it's throwing problems at me like this.

I didn't see what was under that chart so I thought I could do this and wrote

def myGrade(x):
    if x >= 75:
        print("First")
    elif x < 75 and x >= 70:
        print("Upper Second")
    elif x < 70 and x >= 60:
        print("Second")
    elif x < 60 and x >= 50:
        print("Third")
    elif x < 50 and x >= 45:
        print("F1 Supp")
    elif x < 45 and x >= 40:
        print("F2")
    else:
        x < 40
        print("F3")
        
myGrade(int(input("What is your grade?")))

But I didn't see what was under the chart and thought how can I even do this. These problems are so hard. I feel like my head is going to explode I don't think I'm cut out for programming.

there's nothing stopping you, but it's bound to run significantly worse than the same game made in any number of other languages. making a 2D platformer isn't particularly difficult in any language (assuming you make use of relevant libraries), so ease of development isn't a great reason to go with python

1) Where did I say I need pointer arithmetic? I said FORTRAN was a decent language and it EVEN has pointer arithmetic

2) I find Rust to be a shitty language in general. The fact that you need to wrap your code with "unsafe" constructs and the fact that pointer arithmetic is considered unidiomatic makes doing pointer arithmetic in Rust equivalent to doing object-oriented programming in C: Sure you can do it, sure you can probably implement most features, but why the fuck would you add all that boilerplate only to do something it wasn't really designed to do?

Well, he was "socialist" in the meaning "collectivist", but the NSDAP clearly believed in a mixed economy and their economic policies place them somewhere in the center (compared to modern day political parties). Compared to parties in Europe in that era, they were right leaning although not full on capitalistic.

Also, complaining about Java-esque wrapper functions and C#-style "unsafe" syntax is hardly a baby duck syndrome. As long as Rust will do implicit bounds checking and use memory ownership, it will NEVER be able to match programs that access memory directly in terms of speed simply because you'll never gain the benefit of retrieving cache lines.

>>59050306
Not because it has the word "socialism" in it, but because it's literal leftism. Not being the usual kind of it makes it better, but not by a lot.

But it's not.

Social liberalism is a center-right ideology.

No, that makes them by definition centrist.

Centrism != leftism.

Sounds exaclty like baby duck syndrome. If you needed pointer arithmatic so bad you wouldn't even complain about it.

>It will never be able to match programs that are like C
llvm compiler optimization has already reached to a point where Rust is above 90% of GCC C binaries. The jaw dropping 0.05s difference is negligible in modern hardware and it can be traded with some level of memory safety, prevention of data race and dangling pointers.

>>59050429

Pick one.

Only if you mean "center-left", which I would probably agree with.

You can only access one and one member, and your compiler will spill out warnings.

That's barely pointer arithmetics.

You clearly never worked on large data sets.

>>59050476

epic, may I ask why are you not using pure assembly in that case? It's faster than C.
Heck in some cases Fortran is faster than C as well

That's not the definition of left/right, retard. All right-wing parties in Europe, even the extreme far right, believes in welfare.

Anyway, they believed in mixed economy and social conservatism. They have more in common with republicans than any other modern party.

>>59050490
>epic, may I ask why are you not using pure assembly in that case? It's faster than C.
Because it's too time consuming, and correctness is hard to guarantee.

>Heck in some cases Fortran is faster than C as well
Yes, but rarely. FORTRAN compilers haven't received much attention the last two decades. But yes, FORTRAN and C are among the fastest out there, because the compiler is able to do all sorts of magic like using SIMD and fully utilizing data locality to benefit from caches.

>>59050522

This is by definition impossible. It might be considered """"far-right"""" on your shitty continent, but that's certainly not the case in the literal sense of the word.
>Anyway, they believed in mixed economy and social conservatism.
Which certainly doesn't make them right wing. They're center-left at best.

Wouldn't know that much about them but from what I've heard for the most part they aren't right wing.

Everything is leftist if you keep calling it that, eh goldberg?

according to these compile instructions i'm following, after the process, i'm supposed to find a .h file in a folder i specified.

This would by your """definition""" make a large portion of the republican party left-wing.

It's not.

>It might be considered """"far-right"""" on your shitty continent, but that's certainly not the case in the literal sense of the word.
The literal sense is the belief in varying degrees of capitalism. The more capitalistic you are, the more to the right you are. All modern right-wing parties, even in your shitty excuse for a country, believe in certain degrees of planned economy. By your own fucking definition, they would all be leftist then.

>Which certainly doesn't make them right wing. They're center-left at best.
It actually does. Belief in private enterprise and private ownership + reduction in welfare + social conservatism makes them center-right.

Fair enough. Honestly, I would still focus on mathematics, in particular discrete maths when it comes to CS. For algorithm design, check out the book by Skiena, and then graduate to CLRS. If you want a full education on OOP, check out how it's implemented in the popular languages like C++ and Java, then look at approaches taken in languages like Smalltalk and Common Lisp. Their object systems are very different, even though they all fit under the umbrella term OOP.

NSDAP didn't believe in welfare.

They believed in abolition of unearned income, which includes all sorts of welfare.

>>59050663
Source? That would certainly increase my opinion of them.

>>59050674
Their party program is like 25 bullet points, and abolition of unearned income is point 11.

Fucking hell, only mothers and children were allowed to not work. Any adult either had to be in school, military or workforce, otherwise you were viewed as a degenerate and on accord of the moral code Germanic race.
