why does go come with a http server? i seriously don't know why programming languages would come with libraries that make it easy to host http servers

Anyone here use a standing desk?
If so, would you say you're more/equally/less productive/effective with it than a normal desk?

>>60800340
Go having an http server is probably it's only redeeming feature, it's managed to carve out a niche being an ideal language for server backend programming.

>>60799997
Programming is a terrible profession. For one, you are not respected at any normal company. You're known as 'IT' or 'tech' and everyone gossips about how disgusting everyone is in the department. Every day, some Alpha who probably does nothing at his job except get his secretary to suck his dick in his corner office cucks you into doing random bitch work, and then yells at you when it's not done by the deadline despite it being impossible to complete the work requested. Not only that, the code rarely works, your co-workers are smelly Indians brought in by Tata Consultancy and connive to replace your job at all times for half the salary, and the work never, ever ends. You pollute your body with sugar and toxins, deprive it of sleep, and let it rot while you sit the majority of the day, neglecting any healthy exercise, social interaction or life goal attainment. It's like a Postal worker, but coupled with feelings of patheticness, loneliness, helplessness, rage and total hopelessness.

Women, when they hear you are a programmer, instantly remove you from the potential pool of mates as they know your earning potential is maxed early and your career over at 35. They are also instantly disgusted by you. It is far better to tell a woman you are on welfare than to out yourself as a computer programmer. It's also highly embarrassing for a woman to date or be married to a programmer, as virtually everyone knows they are the grown up version of the hopeless virgin in high school. One who never really grew up and became normal and fit into society, but rather found an environment where he could escape the reality of his situation and be invisible, able to hide the toxic shame and utter humiliation that is the programmer.

After Dentists, programmers have the highest rates of mental disorders, especially depression and suicide.

Programmers, why haven't you taken the cyanide pill?

I'm learning C# and was wondering if y'all could review one of my exercise solutions. It's from the book C# Player's Guide. The challenge is attached.

Here's my solution:

using System;


namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            for(int row = 0; row < 5; row++)
            {
                for(int spaceColumn = 5; spaceColumn > row; spaceColumn--)
                {
                    Console.Write(' ');
                }

                for(int starColumn = 0; starColumn < row + 1 + row; starColumn++)
                {
                    Console.Write('*');
                }

                Console.WriteLine();
            }

            Console.ReadLine();

    }
}

Thanks for any help.

programming is an incredibly degrading job that offers 0 job security and is the vocation most plagued by ageism by a far margin. You are not respected at any normal company. Every day, some Alpha who probably does nothing at his job except get his secretary to suck his dick in his corner office cucks you into doing random bitch work, and then yells at you when it's not done by the deadline despite it being impossible to complete the work requested. Not only that, the code rarely works, your co-workers are Indians brought in by Tata Consultancy who will replace you for half the salary and you have to train them to get your $500 severance, and the work never, ever ends. You pollute your body with the caffeinenated jew, deprive it of sleep, and let it rot while you sit the majority of the day, neglecting any healthy exercise, social interaction or life game goal attainment.

It's like a postal worker, but coupled with feelings of loneliness, helplessness and total hopelessness. Programmers are too depressed to go postal, a sad state of affairs. After dentists, programmers have the highest rates of mental disorders, especially depression, transgenderism and suicide.

It gets worse. Women, when they hear you are a programmer, instantly reject you. It is far better to tell a woman you are on welfare than to out yourself as a programmer. It's highly embarrassing for a woman to associate with a programmer, as everyone knows they are the grown up version of the hopeless virgin in high school. One who never really grew up and became normal and fit into society, but rather found an environment where he could escape the reality of his situation and be invisible, able to hide the toxic shame and utter humiliation that is the programmer.

counting the number of times an element appears in a list

countElements :: Ord a => [a] -> [(a, Int)]
countElements s
  = sortBy (flip (comparing snd))
    $ Map.toList
    $ foldr count Map.empty s

count :: (Ord a) => a -> Map.Map a Int -> Map.Map a Int
count c curCount = Map.alter update c curCount
  where update Nothing = Just 1
        update (Just a)  = Just (a + 1)

example

> countElements "help i need somebody help not just anybody"
[(' ',7),('e',5),('o',4),('d',3),('n',3),('y',3),('b',2),('h',2),('l',2),('p',2),('s',2),('t',2),('a',1),('i',1),('j',1),('m',1),('u',1)]
p> countElements (words "help i need somebody help not just anybody")
[("help",2),("anybody",1),("i",1),("just",1),("need",1),("not",1),("somebody",1)]

probably not optimal but I'm still learning.

With auto acks, the transmitter always sends till MAX_RT is set. The receiver interrupt never fires. I put caps across vcc and ground since that looked like a common problem. Also they're right next to each other.

>>60802076
To clarify, what I'm asking is, if stdio is already in std, why did they have to call it stdio. The std is implied by the fact that it's in std. They could've just called it io. And then, as you say, if someone wanted a different io, they could just do uLib.io instead of std.io. On the other hand, uLib.stdio wouldn't make any sense, because then stdio wouldn't be in std, making the term "stdio" a misnomer.

Is it even possible to write a program people will use without relying on pure luck? I swear I've come up with original ideas, only to find they're already actively developed.

How many layers does your network have?

Because both the sine function and XOR can't be represented as a linear combination of the inputs. On the contrary, a linear classifier can actually do very well on MNIST. Specifically, you can get to like 93% apparently, which is kind of around what you said.

Yeah, I agree. All I can tell you is, it's failed on problems which require the slope of the output neuron to change and are thus not linearly classifiable (sine, XOR). It's also succeeded on MNIST, but only to the extent a linear classifier can (maybe a tiny bit better). And in addition, in the image you attached the output is monotonically increasing the entire time (even though the slope almost becomes 0).

So, I can't really tell you what the bug is, but I would use that as a basis for looking for problems.

Of course sissies are inferior, you can tell that much just from looking at them. They're soft, smooth, curvy, fragile, and naive. That's kind of a big part of what makes them cute and fun.

I'm trying to learn to code for fun, and I cannot read any more fucking documentation, or do any more cutesy little controlled examples. I need an actual project, but I can't think of something I'd want to do that's in my skill range, or just far enough outside of it that I wouldn't just be going right back to reading documentation to even hope at starting. Any suggestions?

Also, half-related, I've been learning Java because it's the meme, but I'm willing to shift if there's a better language for beginners. I'm not trying to rush headlong into things so I'm alright with it being not immensely useful outside of being a tool for learning.

I was just suspicious, since monotonicity is a feature shared in common with linear classifiers. Since that data's a counterexample, it's not the case, although if it's rare as you say, it could be statistically the behavior which defines your accuracy.

The problem is for a beginner, questions are NOT language agnostic. It's not the way a beginner programmer who's never seen a different language thinks at all. An answer in C++ is useless to them. They don't have the skill to analogize between syntax and semantics of languages since they don't even fully understand one of them yet, let alone two.

Also, I don't use StackOverflow that much anymore - I'm saying back when I was in that learning phase, I relied on it heavily to understand error messages.

>>60802866
The second entry is one of the tricky ones since it's a denormalized float.

It's kind of hard to see the pattern when you have only 2 exponent bits (easier with 3). When the exponent bits are 0, instead of the exponent being E=(e+B) where B is the bias which in this case is B=-1, E is B+1. (in other words, the exponent is the same for e=0 and e=1) The reason this is is because in that last segment where e=0, denormalized floats happens. This is to ensure a smooth set of steps from the smallest normalized number (where e=1) to the actual floating point value 0.

The other consequence of denormalized floats is that since you're trying to actually get close to 0 without changing the exponent, the "invisible first digit" is now 0 instead of 1, which is why you that the mantissa is less than 0 if and only if e=0.

>>60803037
Data would no longer stored serially. It would be stored associatively at hardware level. Symbols and references would stop being abstractions over numerical addresses, because addresses would not be numerical. The way memory was allocated would change completely, due to the fundamental change in the nature of the hardware involved, and these changes would make explicit deallocation unnecessary.

>>60803068
Wouldn't that be inefficient though? I mean binary addresses are as compact as you can get. So your "symbolic" store would provide a smaller address space for the same address size.

>>60803082

There is no simple trick or secret save for this: most developers write scripts not programs. Knowing the basics is literally all you need in the professional world ( ie an actual company).
Very few corporate developers write entire programs. Those are the elite among even the employed developers. What 'noobs' dont understand is that companies have large code bases and working programs that often need maintained or improved by the 'basics'. This requires fixing it with an often small amouny of code to actually make work since the framework already exists. This framework is (roughly) called the architecture, and is the design and implementation of software. That is a whole new beast.
Once you know the basics then you know what you need to know to be an entry level developer. This is hard for the 'noob' because they feel like that cant be all there is. Well to bad. It is. Writing larger programs is still just stringing multiple smaller scripts into a larger file to hold it all in one place.
O and did i mention that i had a relatively unreleated degree (bs and ms in mathematics) when i was hired to be a developer? I learned from the same websites and books as everyone else when i got here.

is this true?

I wander. Is gender a float or an integer?
I would assume an binary integer set since it can only be in 2 actual states: 0, and 1. but according to feminists the value is (pardon my mathematical imcompetence) an floating point vlaue with an infinitesimal range between 0 and 1 which approaches 1 but never quite reaches it. (1 being men because it looks like a dick).

so non-queer pseudo-male trans-transitional cis male = 0.9999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999 which more or less equals cis male (1.0).

i suppose. you couldn't really parse from a .jpeg in the same way as you would parse from a .txt

I have no clue what an actual file reader does, so a meant a literal file reader (a program that parses a file to look for a specific section).

Gender is a concept made by a pedophilic child molester named money. It has no basis in biology. The correct answer would be that thre are only 2 sexes. Know the difference my friends.

There is no golden road. Though gradually pick up data structures and algorithms as you go along.

>>60803922
Your goal shod be to create stuff as you practice. Challenge yourself with S.M.A.R.T goals for programming, like i did with making an arithmetic program (which took 3 hours to do since im a newbie to java).

Give me the .exe so I can install it, senpai.

I dislike following tutorials - I feel like I'm not actually learning and just copying/pasting.
How bad of an idea is it to just go through the list of basic ideas like Hello World, parsing, etc by Googling anytime I get stuck instead of following a carefully made tutorial?

I can follow tutorials just fine and can understand the basics but it just bothers me since I feel like I'm not learning and literally just copying down what some guy says. Kinda like following a diagram to build a lego house instead of doing it yourself.

>>60804042
When following tutorials, I always type the program by hand, never copy paste. I do agree that doing projects on your own is better than tutorials, though.

Pick a lofty goal and build the simplest version of it you can imagine. Then keep improving on it.

The problem I had with a community college programming class was that the teacher wanted us to copy his code, type if obviously but just copy it.

It bothered me because it was less "I need to make the text entered into numbers to do math, how do I do that?" and more "enter this code and you can now get the percentage increase"

I'll look into doing things myself then, thanks, anon

>>60804111
Kinda dumb question but assuming that with books they're based on old version of languages, good or bad idea to read them anyway? Bceause one issue I came across for C# was that most of the guides were for VS from 2013 or earlier.

>>60801600
>C family is intolerant of failure
Web dev languages - JS, for example - are almost universally in the C family, you idiot, and the C family is known for it's weak typing and procedural code which allows the end user to basically type random tokens from the language and get valid code.

>>60804123
with C++ it's probably best if it's written with C++11 or newer in mind but i'd say it's generally ok to read an older book and you'll be able to pick the newer features up quite easily

>>60804123
It depends on the language. C has K&R, which is still a great manual after 30-odd years, but if you picked up a book on something more recent, like Python, you'd be shit out of luck.

>>60804123
When doing the copy-by-type thing, I will have these ideas like "ah ha! what if I rewrite it like this? is that equivalent?" or "oh ho! how can I modify this code to do ___?" Following up on these thoughts almost always leads me to good learning experiences.

I'm working on a markup interpreter in C++. Starting with JSON (easiest); it takes a haml-like syntax and outputs valid JSON.

Hello guys, i have stupid question.

I'm programming script in python that exports excel files to propiertary format. I have made that i get excel files from dir listing and problem is how to make new file for every excel

heres example.

exceltosomething(excel, "filename.meme")

so how to make that filename.meme would be like data.xls.meme automatically.

sorry broken english

>>60804345
oops. i mean

like in multiple files that it makes from data.xls to data.xls.meme and data2.xls to data2.xls.meme

>>60804345
Get excel file name, store in variable. Call it something like filename. Then:

exceltosomething(excel, filename + ".meme")

If i is an integer, that should work. On the other hand, you're treating that modulo expression as a Boolean when it returns an integer; meaning so long as the expression's evaluation is > 0, it will be true.
If you're testing for even numbers, I think you would want arr[i] % 2 == 0.

like network admin. It's such a great field, and just too fuckin easy to get into. The whole thing runs off of certificates, degrees don't even matter.

You can get all the study materials you need offline easily, and can just go take a cert test when your ready. If you fail you will know what to study more and can go do it again and again, just costs money. once you get the first couple certs you could be makin 40-50k.

After you get those you want to work of gettin job exp along with more certs over time, and with the money you made you could just go to school to get the next certs on the list. 4-6 years later you will be makin 6 figures son.

Your job: Find network issues in a companies network/tell a company how to layout their labs and what cables, pc's, routers ect they will need to accomplish their goals while staying in budget.

It can be a lot of staring at a pc, but also a lot of cash money.

 teamRepository.findAll().stream().map(Team::getName).sorted().collect(Collectors.toList()) 

Noob question
Can anyone explain me what each method does after the findAll() ?

>stream
puts everything into a stream, to do all these other cool operations on
>map
takes every object in the stream and "maps" it to another object, based on the function inside. It can use a lambda operator, or in that case, a function based on a namespace. This maps a stream of Teams to a stream of their names
>sorted
sorts them based on either custom comparator as input, or in your case default comparator
>collect
puts the stream into something useful. In your case it uses a built in collector called ToList, which puts the stream into a list in the same order.

So your thing takes your team list, and returns a sorted list of their names.

I'm the same way but i've found that some tutorials can be pretty nice, just the sheer volume of exercises will get you a decent baseline at least. Also there do exist tutorials that don't do all the work for you, CS50 is a pretty good one where every exercise I encountered required critical thinking and problem solving. It tells you what you need to know but it leaves you to implementing it.

if you're intelligent enough it just comes as naturally as anything, as natural as up/down/left/right, x/y/z, 1/2/3/etc, riding a bicycle, once you've learned it it's automatic

do you need mnemonics for tying your shoelaces, finding sin/cos/tan in a right-angled triangle, or for figuring out what 2+2 is?

>>60805825

No, but I personally have very bad spatial cognition, and when I'm using a screwdriver at a funny angle or upside-down or just somewhere I can't see well, it's very easy to close my eyes and repeat the mantra.

But you miss the point. For the truly intelligent, the value of a mnemonic device is in easing the transmission of knowledge to others. You fucking faggot.
