"I think you're attractive, and I'd like to cuddle with you at my house. Here is my number, call me when you're done with classes today."
Worst case scenario, she doesn't call you.
>>53680675
No, worst case scenario she gets worried about her job and puts in a sexual harassment complaint into the university so there's no way she can be liable if some autist claimed she was flirting with him.

this is really confusing me. i've read the instructions and in some parts it's literally saying just to copy some of the stuff from the book, but the book's a couple hundred dollars and i don't have it. am i storing the list of cities and the list of adjacent cities in 2 separate data structures? i don't understand why it isn't just 1 file with the name of adjacent cities.
when i look at a problem like this it seems to me like i would want to make a bunch of city nodes with a string and MAX_POINTER_COUNT number of pointers pointing to connected cities. Then to have an array that saves the location of all the cities for easy scanning, and then just make the city node connect to whatever city the input file says it should point to. but it doesn't look like that's at all what we're doing. at all

this is the flightmapinterface. the file i was given also included a couple other skeleton files. i was given a city class, a determinepaths class, and a stack interface to implement. i already implemented the stack using an array. i was also given a node class, but the instructions said that if you implemented the stack with an array you could just delete it which i did

Is there a generalized XML reader?
i'm working with XML for an assignment. (supposed to convert to csv). It seems like for 90% of the XML i could just read each attribute for each element and have that be the fields for the csv. then I'd take each bottom level and create a csv line for each.
but the problem is at the bottom level two of the fields I want aren't attributes but bottom level elements..
This probably doesn't make any sense but is there a better way? Right now I'm just thinking of recreating the class structure in the program then manually creating loops to get all the info. It doesn't seem very elegant but the data structure isn't totally consistent.

Generics are compile time, reflection is run time. Protip: an array holding different types is really bad practice. See what happened to Belgium.
>>53681933
the java standard library already has a HashMap
if your "objects" can be used generically they're either not very interesting objects or you're not doing something interesting with them
go doesn't even have generics, should tell you something about how useful generics are
use an interface or something if you have different objects that you want to operate on with the same algorithm. there's no way you can do something interesting with ALL objects outside of very basic things like storing them in an array or hashmap

Why does PHP get shit on so much? I've developed numerous useful applications for it. It's also the only practical way to integrate things like payment processors into a website.

It's a badly designed language with a lot of caveats and lack of consistency created by someone who proudly claimed to "have no idea how to write programming languages" and "have no idea how to program". It started as a toy language for one person to ease a few tasks that hasn't had any thought put into the design whatsoever and accidentally ended up being widespread.
This doesn't necessarily address all of the bad things about PHP but should give you an idea:

fucking magic
for example, you can bind every method that matches (or doesn't match) some criteria X in some class Y (or classes extending Y, classes that Y extends, etc...) to invoke an additional, written by you, method before or after (and even during) its own invocation
and that's just one small thing
there is a million ways to describe the precise conditions in which something like that takes place
without AOP, if you wanted something like this, you'd have to write quite a fucking bit of boilerplate code

My point exactly! I want something usable that helps me and doesn't keep be back just because i haven't learnt yet the really specific way to do a task.
I always return to vim with clang integration but it is limited in many ways.

cmake, for whatever reason, wouldn't expand variables in add_executable blocks. Maybe I did, or did not, put the variable in quotes, and that somehow makes a difference.
Cmake seems to be very particular. Like it kept suffixing library targets with .lib (so it'd be .lib.lib, .obj.lib) until I put it in quotes. Really don't like programs that attempt to correct user error or make assumptions, their heuristics almost always get in the way.
Seems like I'm missing something fundamental. Have to read the documentation more thoroughly instead of trying to piece it together.

Did a little not-so-exciting side project today. Ever since gookmoot ruined /s/ and /hc/ with the 500x500px minimum image size limit, it's been impossible to have threads. Most older scans don't meet the limit. People have taken to actually scaling the images, but that ruins them. In order to do something non-destructive, I figured I'd make a program that just automatically adds borders to all images in a directory that aren't at least 500x500.

that sounds like a 1 liner of imagemagick
if only people had enough years to read the manual
/dpt/ I've never done anything with networking before and I'm making a client-server program for the first time.
I've opened up a tcp socket and now can send data back and forth between 2 or more computers over the internet. The thing is I just made the connection and wrote something around it without having any clue what I was doing design wise, I'm not familiar with practices for this type of thing. Everything I wrote works but I have no idea if it's the right way to handle it. What I mean is, I made some datatypes that I'm calling "messages" and I'm passing them back and forth, when either the server or the client receives them it switches on it and handles it accordingly, is it appropriate to call this a protocol?
I want to know what I'm doing so I can look up some books or something to do it better, I'm unsure if I'm handling this right at all despite the fact that it works.
I essentially just connect the client and server then spin up a thread per client on the server, once established I just block forever on a read of the socket until data comes through, I thought about polling instead but I have no idea what I'm doing with networked stuff, I need to learn how to do it right and maybe rewrite all this.
Another thing bothering me is assuring something was received, do I just constantly send a message and expect a response every time with a timeout or is that something I should avoid with TCP? Can someone point me at some documentation to read on this kind of thing?

>do I just constantly send a message and expect a response every time with a timeout
TCP guarantees (unless the network connection is lost) that all of the packets will arrive in-order, reliably. Application programmers can pretty much ignore whatever is going on below them in the networking stack and just expect it to just be a reliable data stream. This doesn't hold true for UDP though.
If the connection breaks or anything, just clean-up and quit the thread.
Maybe close the connection yourself if a client is taking too long to respond, to prevent denial-of-service attacks on your server.
>Can someone point me at some documentation to read on this kind of thing?
I learned most of the shit I know about networking at university, so I don't really know of any online resources besides Wikipedia articles.

>>53685744

My best guess is that CMake doesn't like the fact that you are mixing newlines and spaces to separate source files. Did you use spaces when defining ZLIB_SOURCE? If so, try switching to newlines.

Managed memory languages have fewer instances of memory leaks because it's handled automagically.

That's considerably more work for the same effect.

Most people that add borders don't do so losslessly. It could be done if they use the same quantization tables and the borders are exactly on block boundaries, but that, to me, sounds like more work.
I can't remember if jpegtran has a means of lossless resizing.
>>53685856
What makes you think that the implementation of C I use does not have managed memory?
Not to mention that this has nothing to do with build systems.
>>53685631
You should look into thread pool and message queues
Also look a bit into UDP, it can be very helpful at times.
The thing here is that the way to handle networking is heavily dependent to the thing you try to accomplish. For simple networking you are fine.
Another thing to consider is how should your program handle network failures. For example if the connection initiates a session what happens on a disconnect? Do you deallocate a session? do you have a cooldown timer? What happens for many connections? What about network delays?
All those things are application specific. You can have many general discussions about networking but having something specific in mind is the way to go.
Just look around for other protocols to get a general idea.
also what the other annon said
>>53685850
I had an assumption that cmake wouldn't know how a variable was set when it was expanded, so I'd set ZLIB_SOURCE's files in quotes. It parsed it all as one argument on expansion.
Works now though. I'm used to working with scripting languages where you need to be careful with whitespace, tab characters, spaces, etc. Habits carried over.
One of these days I ought to actually learn CMake, but it's confusing as fuck compared to just building a Makefile.

This is a program used fairly commonly, and very old.
I think it was to make C more fortrany?

for pi in PG_ID:
rpid = pi.upper()
rpi = re.sub('[\w+\s\.]' + rpn, '', rpid)
rpn = 0 btw
Hi, I'm trying to delete a predictable string pattern which I have captured from a regex. Unfortunately the 'pg 0.xxxxxxxx', is required in order to safely capture the xxxxxxxx values without capturing anything else within the var, output.
What I'm trying to do is remove these predictable characters but I'm having difficulty.
Please refer to the attached photo for an idea of the raw text I am dealing with.
The current method outputs:PG.DFB2D74
So PG still exist, I've tried putting PG in btw and the dot still exists even though it was intentionally escaped.
The space and the 0 (rpn) has been removed though, any ideas?
>>53685809
Thanks for the input Anon.
>If the connection breaks or anything, just clean-up and quit the thread.
That's what I was assuming but I wasn't sure. I intend to have some kind of timer per connection that gets increased every time a full procedure finishes, if anything hangs for more than this timeout I'll just close the connection and cleanup. Same on the clientside but it will just reconnect and start over.
Do you have any advice on how I should handle multiple clients in the future besides 1 thread per connection? I toyed around with the idea of using some kind of state struct with a peerlist and going synchonously but it seemed like threads would be the better option while learning. I'd like to get it right though if I intend to write a non-trivial program.
>>53686021
>All those things are application specific. You can have many general discussions about networking but having something specific in mind is the way to go.
Thanks, that's the impression I was getting when I looked around but it felt odd to me, most people encourage being general or using standard practices so having all this freedom made me question my implementations. It's very cool but a little scary when you don't know what you're doing, everything else I've done had big lists of opinions and practices so it was easy to look up a list of "don't do this ever" and compare it to my programs.

>>53686116
It's fine for toy programs, but it's not a good habit.
The whole point on namespaces is to avoid name collisions. If you use namespace std, you've just polluted your namespace with god know what names, defeating the purpose of the std namespace.
>>53686105
>Do you have any advice on how I should handle multiple clients in the future besides 1 thread per connection?
Create a job queue, with one thread listening for connections and adding them to the queue, and many other threads taking jobs from the queue and handling them.
Threads aren't cheap to create and destroy, so this way, you can create all of your threads up front and use them over and over again.
>>53686116
yes, basically because it pollutes the namespace, a halfway point would be "using std::(whatYouNeed); instead for each class in the STL, but for toy programs or if you are in a rush, just using namespace std is fine. Also, if you get tired of typing that you could throw it in a header file and include that with your custom defined classes.

You miss the point, if you have a header file with using std::vector or std::string and include this header file where ever you need to use the STL, then you only update it in one place, you don't pollute the namespace, and you no longer have to qualify your statements with std::

Not really. Using a namespace doesn't really make too much sense in other languages either. In Ruby, it would be rather silly to do something likerequire 'mymodule'
include 'mymodule'
Because that pollutes the global namespace as well.

The Scanner will automatically filter whitespace for you. What kind of whitespace is filtered can be manually set at the stream variable. By default it's spaces, tabs, newlines, etc. The next() method will treat the entire input as a single sentence and parse it word for word.

Ruby and Python don't use headers like C and C++, and yet "using" a namespace like that is discouraged in them just as it is in C++. That is what I am pointing out.
