Well, I'm learning how to use objects. I made a variable containing three keys which are all simple functions. I'm trying to run an input through all three functions and log it to the console with a for... in... loop, but I'm not sure how to do it. I can't seem to get the input to actually go through the keys themselves.

>>56372663
Follow the fucking well-established OP format. The OP isn't your personal shitposting space.
Adding a bunch of shit into the OP and/or posting a retarded image will set a terrible tone for the entire thread, and there will be much more shitposting overall.

I'm working on a desktop wallpaper randomizer that supports multi-monitor setups. Its working great, but only on GNOME right now. Is there some *nix way to set the desktop wallpaper without having to worry about figuring out what DE/WM the user is currently running?

Otherwise, I'd just have to write some routine for every fucking DE/WM out there... Right?

I originally started this because I'm too dumb to figure out if feh can set a different image per screen, but now that I'm generating one image that spans all the screens, using feh would be simple.

Thanks, anon.

There is the stock XORG desktop that you can set with nitrogen or feh, but every faggot DE draws their own in a layer on top. So you will need a switch case for every one, sadly.

No, you've completely missed the point.
It's something that everyone should be able to do.
Not something you should memorise and then be like "I've done this before" - it's something you should hear as a task and think "this is fucking easy"

>>56373006
C# is considerably better, but still very marketable. Also less Pajeet poo in your code base to clean up.

>>56373008
yes I've been a programmer for 10 years in node.js and I can tell you it's the most common interview question I've gotten. Once you know it you know how to program

>>56373006
Java easily has the most jobs, but C# is second place in that regard, significantly higher than Python or C++.

It's also much nicer than Java to use.

Previous Thread: >>56365584

>>56373069
This is the new /dpt/ template. It is superior.

>>56373112
superior in patheticness, yes

I sent over 200 individually tailored resumes since March (manually). And I went to about 8 interviews but got rejected from all of them. I believe tech interviews are totally f***ed up. I have been asked so many ridiculous questions that makes me sick for days just thinking about them. Every job posting I see asks for "SENIOR DEVS".

So I'm going to take a different approach. I believe in the numbers game. There are ton of companies out there. But its impossible for me to find them one by one.

So I'm building a bot to speed up this process: 1- Find a list of all companies 2- Filter only those companies that hire software devs 3- tailor my resume based on specific keywords 4- send emails 5- reply and arrange interview based on my schedule.

Currently I'm working on the first part. The bot finds a list of companies using major search engines. Each search engine has a certain query limit. So I use proxies to get around it. And when the system runs out of proxies, it starts data processing till the query limits are reset. Currently the bot harvested about 895,000 companies across the US. But only 9000 has been processed to see if they hire software developers.

For the data processing, I used AWS at first but it got pricey very quickly. So I built a nodejs version of my bot and used socket.io to handle connections. I run the bot as a daemon on each one of the library computers of my University. There are about 80 computers that I can access without credentials. Also I connected my slack bot to get live status from each processing node. I think at some point the system admin will notice the unusual CPU loads. So I renamed the nodejs process as chrome and I run the bot during busy hours to make it look like people are using chrome on those computers.

Anyway, so the only important part left is to automatically tailor my resume based on keywords. I don't exactly know how to go about this. Do I need to use some kind of machine learning method?

Can we get some more of these?

In a book I'm reading there's a question: What is a statement that introduces a new name into a program with memory set aside for a variable called? Is the answer declaration or definition? I assumed that a definition was for defining behaviour of a function whereas declaration is the right answer?

Scheme is good for the huge amount of recommended reading material on it. If you read the Schemer books and SICP, which you probably would while learning Scheme, you'd be a much better programmer and computer scientist overall.

Discord is a comfy program to use but the fact that they give you free servers but it doesn't have any obvious monetization scheme spooks me.

How likely is it that Discord surveils everything you say and then sells a dossier on you to targeted advertising firms?

>>56374020
I don't know how it would be best expressed in Rust, so I'll just use Haskell.

foo :: (forall a. a -> d) -> b -> c -> (d, d)
foo f b c = (f b, f c)
-- foo show 10 "Hello" = ("10", "\"Hello\"")

It works in Haskell because everything is boxed, and polymorphic functions can be implemented with void pointers. The existential part of higher-rank polymorphism can just be fat pointers, which Rust already has.

>>56374050
Higher-kinded =/= higher-rank

>>56374198
Of course they do that, you numpty. You are the product.

>>56374198

>>56374198
If you don't pay money, you're the product.

That being said, they don't care about you, specifically, and they're not selling a dossier on you, specifically.

The value comes from the aggregation of the millions of users, and what keywords they use, etc.

>>56374210
Regardless, you can't do either in Rust.

>>56374210
>(forall a. a -> d)
Give a non-trivial instance of this function
Non-trivial meaning "not const"

>>56374020
>>56374210
Oh, and it ~could~ work in Rust as long as the polymorphic type variable is only used behind a pointer, e.g. &T, Box<T>, etc.

>>56374189
Let's see some benchmarks.

    notPrimes = set(notPrimes)

    i = 3
    x = []
    while len(x) < len(words):
        if not i in notPrimes: x += [(words[len(x)], i)]
        i += 2
    return x

    if len(argv) < 3:
        print "FizzGen requires at least 2 arguments. An int, and some strings."
        rangeLimit = 100
        primes = [("Fizz", 3), ("Buzz", 5), ("Bar", 7)]
    else:
        rangeLimit = int(argv[1]) + 1
        primes = generatePrimes(argv[2:])

    for number in range(1, rangeLimit):
        print ''.join([ 
            string

>>56374312
It's less generic, so it can be used wherever the latter is expected. It just puts additional constraints on the rest of the parameters:

foo show :: (Show b, Show c) => b -> c -> (String, String)

>>56374359
In retrospect, the higher-rank lifetime syntax extends perfectly to types, so I should have just used that in the first place.

The only way you can avoid duplicating the divisible(x 3) is by calculating another divisible or by holding a variable in memory. This is an example of acceptable duplication because you only have to deal with checking if a modulo of a number equals zero anyways.

I wouldn't call it basic functionality, but it is surprising that they don't even seem to want to consider it. To be fair, a lot of the use cases for higher-rank types in systems programming are subsumed by Rust's lifetime system, which does have higher-rank polymorphism (presumably because lifetimes are erased and don't need monomorphization).

The lead language designer said this about the lack of polymorphic recursion:

It only takes a bit of creativity to implement higher-rank types without boxing everything.

It's horribly designed, the syntax is just plain silly, and i/o is a pain in the dick with it. The obsession with what the Rust devs define "safety" as makes it completely unusable. Effectively, it's C, but ever so slightly worse.

Go check how you implement an input-prompt in Rust and you'll see why it's shit. Compare it to Golang's -

reader  := bufio.NewReader(os.Stdin)
in, _   := reader.ReadString('\n')

which makes at least a thousand times more sense.

Not really a fair comparison because interpreted vs compiled, but in DeviousYarn, it's just "x = in", and in Python it's just "x = raw_input()".

If you want to make your Rust code one step more of a pain in the ass, try comparing the text you got in your prompt to a hardcoded string.

Rust safety is no memory errors. It can crash and get stuck in an infinite loop, but safe Rust code can't lead to an exploit, it won't corrupt your kernel, etc.

If all you want to do is I/O with some processing, Rust isn't the right language for you. Nor would C++ be, nor C.

Go has no templates / generics, which encourages unsafe usage of void pointers ("interface {}" in this case)

It deliberately disallows operator overloading, which makes working with vectors and matricies fucking impossible.

A lot of built-in types are "special" and have functionality of a sort users cannot define themselves (I think Go's foreach only works on builtins, yeah?).

Stop-the-world garbage collection makes it impractical for large classes of problems.

The package manager just pulls the latest version of the head branch from the repository of each package you define, which is pretty much guaranteed to break shit constantly. The solution to this is vendoring, which can cause legal issues.


...That said, Go is the best language for its primary niche. That is, building servers, especially servers which don't do much business logic but instead just coordinate I/O operations like multimedia CDNs. I think Go is actually a good language if you think of it as a domain-specific language for building servers in. The central role of channels and CSP coroutines make a lot of sense from that perspective.

I bet the money was fucking shit

>>56375211
No, thank you. OOP is a good tool in some use cases, but I don't want to end up overengineering my class clusterfuck, when a procedural solution is easier to read, write, lower on memory and likely faster.

In the UK, how to get a coding job in America?

>>56375280
Betting is huge in the UK

>>56375310
Move to America

>>56375330
ok
so how much money did you make?

>>56375340

I'm sure the procedure is, get a job, then get an invite to the country, this makes things a lot easier.

Anyone Python around here?
If so, can you explain to me why code related returns A C B instead of A B C?

I mean i can still go through the loop just fine, but why does C go before B?
The syntax is correct so far as i can see.

No.

It could be, but I just cooked it up fresh. Repost it if you're a spaghetti aficionado.

Dictionaries are not ordered by nature, you could fix this by calling for key in

 sorted(dict.keys()) 

, this is because of the way hashing works. Hashing generates a bunch of buckets with distinct values, you can't necessarily access those buckets in order.

>>56375408
I swear I've read the exact sentence about vendoring being illegal here before.

>>56374848
Yes. Actually, that's exactly what they did.

>>56375392

for key in sorted(dict):
    print(key, " ", dict[key])

I believe you can do this to restore order so it prints out A B C. >>56375413 beat me to it.

>>56375426
Probably because I've been posting the same complaints about Go for a while.

>>56375030

The main problem is that doing low level embedded unsafe Rust, which is supposed to compete with C and is unavoidable, it has worse defined behavior and is ridiculously more verbose than equivalent C. I would wager the UB is even worse than C++.

Until they sort that part out, it won't become anywhere near a better C. And linking jemalloc by default is stupid.

No thanks.

>>56375413
>>56375444
Thanks. That explains a lot.
Though i'm hesitant to sorted() my dictionaries every time i want to go through them.

>>56375392
As a sidenote to other comments:

Do not use dict as a variable name, its a build-in type..

Instead of iterating over a dict like that which re-hashes every key and does a lookup, do this instead:

for key, value in d.iteritems():
    print(key, ' ', value)

Use items() instead of iteritems() if python3.

With jsoup i did this
https://jsoup.org/apidocs/org/jsoup/Connection.html#validateTLSCertificates-boolean-
So it doesn't validate certs

Now how do i do it with okhttp?
I need to manually add the certs? is there any way to not validate the certs?

I can't do anything serve side because it's not something i have access, it's not mine

No difference to the go versions

in, _   := reader.ReadString('\n')

where you dismiss the error by writing ,_.

If you check it (which you should) and don't want to panic if the line can't be read

if let Ok(text) = line {
    println!("input==test? {}", text == "test");
} else { ... }

go would look very similar

The order in which the dictionary is handled keeps changing every time i run the script.
Even sorting before starting the for loop doesn't guarantee a singular order.

Am i overlooking something or am i just too new to Python to notice my error?

>>56375581

Why do you say that?
What state?
How much pay?

>>56375631
The things said in the other replies still hold; dictionaries are not ordered.

So you either call sorted() on the dict while iterating over it, or you can for instance use collections.OrderedDict which is a dictionary that remembers the order in which keys were inserted.

I get what the others were saying.

I got hung on what sorted() did.
I thought it just sorted lists and dicts, but i guess that's only when it's being iterated over?

I mean the sorting doesn't seem to stick in pic related.

    for(int i = 0;i<int.MaxValue;i++)

    }

>>56376011
Neverfucking mind.
I forgot to store sorted(l) in l

Be nice, i'm new to this.

>>56376011
I advise you to look at the python documentation.

sorted() returns a new sorted list.

If you want to do an in place sorting you have to do:

l.sort()

Don't mind me, just using this dying thread to figure out how code tags work.

l = ["a", "g", "d", "c", "e", "b", "f"]

l = sorted(l)

for letter in l:
    print(letter)

https://en.wikipedia.org/wiki/Bracket

{ } – braces are "two connecting marks used in printing"; and in music "to connect staves to be performed at the same time"[3] (UK and US), flower brackets (India), French brackets, curly brackets, definite brackets, swirly brackets, curly braces, birdie brackets, Scottish brackets, squirrelly brackets, gullwings, seagulls, squiggly brackets, twirly brackets, Tuborg brackets (DK), accolades (NL), pointy brackets, or fancy brackets
