I have general question about C if anyone knows the answer, when implementing a generic swap function why would one implement it with pass by value instead of pass by reference, is there some disadvantage to just swapping the references to the variables?

I need to output two backslashes in python and i cannot plz halp
timber violet
print("\\\\")
no no no
4 slashes will print two
i dont know why discord deleted two of mine
royal sonnet
ok thanks
timber violet
sure thing
small escarp
@royal sonnet that behaviour is because of escape sequences
which is used to print invisible chars and similar things
so \n becomes newline
and \\ becomes \
it can get ugly when you're dealing with paths,
so you can use the raw string literal construct to remove this behaviour

i want to turn only the diagonal elements in a list to 0
for rval,r in enumerate(a):
for cval,i in enumerate(r):
if(cval == rval):
a[rval][cval] = 0
this turns everything to 0
what m i missing?
timber violet
the problem is that you are not adding to rval & cval at the same time. you are iterating through every element. You dont need two for loops. Use only one for loop and iterate both rval and cval.
imagine a 2d array as an xy graph. y=x is essentially what you are trying to do.

So I have aΒ PHP script that will serve users a photo based on a GET request.
<?php
$file = $_GET['i'];
$size = getimagesize($file);
$fp = fopen($file, "rb");
if ($size && $fp) {
header("Content-type: {$size['mime']}");
fpassthru($fp);

header("Content-type: image/png");

readfile("https://i.ryois.me/404.png");

readfile("https://i.ryois.me/{$file}");

Is there some way to add a GET like ?i=myfile.png&c=1 where c=1Β will tell the script to compress the image before serving it to the user?
Im using PGP 7.1.7 on IIS.

Whats the name of an unpredicted error in code that Grace Hooper used, and is used today
is it bug or defect
upbeat folio
I'd guess defect. The term "bug" comes from the early days of computers, when literal insects would crawl inside computers and bridge circuits, causing unexpected behaviors. This meant that early debugging, outside of checking your code, meant making sure there wasn't a dead roach inside your mainframe.

For a discord bot, should i use a local database (MongoDB) or an abstraction on top of google sheets? im leaning toward sheets because that allows it to run on any computer that can log in.
nocturne galleon
@here how do i even get gud at coding
i know a little bit of java
less kotlin
proper gale
you dont get good, you git good.
nocturne galleon
and some HTML/css
little knoll
@proper gale It depends of how much your bot need to read/write data, I'd recommand you to have a local DB tho, you can use something like SQLite, it runs with your app on all systems, or just use json files.
proper gale
minimal amount of read/write and total data
its private bot, and i could always change it later.
@upbeat folio the first documented use of 'bug' to describe a computer not operating as expected was on a stanford research computer when a moth was trapped between contacts in a thermionic valve. there is a wikipedia article on it.
it was not a bug crawing in the mainframe, but rather one manufactured into it.
would it make that large of a difference, @little knoll?
little knoll
You would have to rewrite a lot of code to implement a DB system after that...
proper gale
nah, ther would be an abstraction layer inbetween anyway, so just that part.
little knoll
Or you could use your own "DB driver" and so you would just have to rewrite it to switch to a DB system
Oh well..
proper gale
yea, thats basically what im doing
little knoll
The only issue would be rate limit and "I/O" latency (for Google Sheet thing)
proper gale
so the backends im looking at are mongodb (im running it in different jars so it needs to be external) or google sheets (anywhere)
little knoll
Or (if you work with nodejs) you can use NeDB, a local standalone MongoDB like system.
proper gale
Java/Kotlin and Discord4J
little knoll
Ok... So it's not an option ^^' So yeah, you could try it, it should work, but if you want to try something else for the anywhere scenario, you could use SQLite or json files to store your data.
proper gale
ill probably go with mongo
upbeat folio
@nocturne galleon The best thing I can recommend for learning how to code is learning how to read code. Once you've got the basics down (which you can pick up from just about anywhere), peruse some open source code to see how other people have made things work. If you find something you don't understand, get ye to Google or StackOverflow (or even ask here). And also, try not to get discouraged if your code doesn't work the first time - practice makes perfect, and every developer worth their salt tests what they've written before publishing to make sure it works.

Hi! I'm having problems with sessions in java (servlets, jsp and filters).
So let's take admin user for example.
So the case is that I have login page which works fine.
After admin has entered username and password correct it redirects to "/admin" where is index.jsp. (I have Filter that checks if the user actually has logged in. the filter url pattern is /admin/*)
On the index.jsp I have <a href=""></a> to another jsp page but when I click the link it seems that the information about the user on session has dissappeared and filter redirects me back to the login page.
small escarp
haven't seen servlets in a while, but how are you accessing the session?

@small escarp So after user has filled in the form and pressed the login button it then goes to servlet in server side (the user doesn't see the process on client side). In the servlet I check if those parameters (username and password) from form are containing something. If those parameters succesfully contains something and aren't null then I run query on database that checks if there is a user or not with those credentials (the method of the query is on a different class).
Now to the session. So after the method that checks from database if it found the same username and password finds correspongding user it then returns a new User object (which has all of the information about the user) to servlet .
Then I have method "forwardAdmin" which takes HttpServletRequest, HttpServletResponse and the User object (that the login method returned earlier).
Method parameters are HttpServletRequest req, HttpServletResponse resp, UserBean user
And I call the method and give those parameters to it. Inside the method I'm setting the session with "req.getSession().setAttribute("user", user);" (the attribute value is from the method parameters. The whole user object that login method returned earlier)
then I use "resp.sendRedirect(req.getContextPath() + "/admin/");" to send them to the correct page.
Hopefully this helped you to understand more what is happening.

@small escarp I solved my problem. The problem was on the filter. So what I did wrong was that I checked if the requeseted url was same as "/admin/".

I simply changed to check if the url contains the "/admin/" and now it works properly

So I've been thinking about making a easy to setup version of Taran's second keyboard (the idea being that you would run an app that would generate the boilerplate code, then you could download i.e. a pack for a certain app to use as a second keyboard.
Thoughts?
upbeat folio
@weary vortex A bit late in replying here, but the way you have it set up, you're returning userId before it's been defined. Node.js is a synchronous language, which means it (essentially) fires all of the commands one after the next without waiting for the previous one to finish. As a result, you're logging userId before the get request has finished (or likely even started).

@solid horizon if you want efficiency searching neighbours you can use a matrix class
or a sparsematrix class
through multi-index arrays or arrays of arrays (or hiding index calculations on a simple array through the class interface)
upbeat folio
@weary vortex You should look into promises, and get to know the Bluebird library (which is one of the best out there). It's a really good way to run code asynchronously - so tell the code to wait for certain replies before continuing. In your case, you'd probably want to do something like...
small escarp
if for some reason you have tons and tons of blocks and are extremely sparse, you can use a k-d tree/octree or some approximate nearest neighbour algorithm

request.get(request_options, function(err, response, body) {
if(err instanceof Error) {
reject(err);

// Use 'let' instead of 'const' since the scope is much more contained.
let result = JSON.parse(body);
resolve(result.users[0]._id);
})
}

resolve(user);

I'm still relatively new to node.js so its quirks are still weird to me
by trade I'm a C#.NET programmer lmao
upbeat folio
It's definitely a strange beast coming from anything related to C, lol
I started in PHP, so I know the learning curve
but yeah, if you use Promises like how I outlined, it should make things easier
The idea is that a Promise tells the code to wait until its resolve() function is called, and if you put that in the callback, you can program asynchronously. Calling resolve(something) actually runs the callback that you outline in Promise.then(function(something){})
(I also recommend checking out the Bluebird library, which is actually more powerful than the native implementation of JavaScript promises)
weary vortex
will do!
shelved the project for now because of work etc. but i screenshotted this convo for future reference π
i will definitely use this advice in future
solid horizon
@small escarp thanks tho i have no clue what that means lol, but ill look it up
autumn mulch
@weary vortex regarding promises, nodejs comes with promises baked in, no need for the blue bird library.
But the code above still works
Also @upbeat folio nodejs is asynchronous - synchronous is where you wait for the last command to fire then move on to the next command. It even says on their website (in effect) - but don't worry, we all make mistakes from time to time.
@weary vortex you can also look into async await syntax, which though I do not understand it completely, is essentially a wrapper around promises
vestal glen
(it's a wrapper around generators, making working with promises much nicer)
vestal glen
(https://www.npmjs.com/package/co is how you'd do it before the async/await sugar)
autumn mulch
Also here is why nodejs is asynchronous: https://stackoverflow.com/questions/17607280/why-is-node-js-asynchronous
Isn't it better to use built in code? Async/await has been in nodejs since v8 LTS
But yeah, good point if he uses v7 or lower
autumn mulch
As footnote, the asynchronous and synchronous are confusing names as synchronous would imply things happen at the same time (which it essentially means the opposite of) . Then again Js calls generator functions generators when they don't really generate anything and Linus Tolvards decided to call git, well, an English swear. Programers name things in weird ways.
vestal glen
also, js always only runs one line of code (except for workers...), which is why you may call it sync in some way, though that's how the runtime behaves, not how your code behaves. You can still have race conditions...
generators are built to generate sequences
it's just that you can misuse them.
autumn mulch
Makes sense.
:)
(now I know why generator are called what they are called, all the example I saw made it look more like some form of user controlled step by step function)
Thanks!
upbeat folio
I prefer Bluebird for some of its more advanced features like concurrency control for promise maps and the like, but Iβll definitely give the await syntax a look. Thanks! π
autumn mulch
You are welcome!
upbeat folio
Also, yes, it is single threaded so it does only do one thing at a time, but when coming from PHP, I found it helpful at first to think of it as trying to do everything at once. This video, though, gave me a much clearer understanding of exactly how the event loop works, and how the various parts of Node interact with each other (note: it's long, but also good).

If you need nic drivers you can try downloading their package and transferring it via a usb stick or something
dawn geyser
@fringe wagon you would have to check if your nice drivers need to be loaded or installed. Did you install a precompiled kernel or build your own? It's been a really long time since I used arch Linux but I remember it used to ask certain questions on the kernel side of things. But run an ifconfig command and see if you have more than just the loop back interface. What hardware are you running on and are you hard wired or relying on wifi?

@tidal dune so many things with electron these days π¦ And most of them don't really need it, they just did because it was cheap.

I use electron sometimes because I like JS.
It's very slow on my Mac Pro though.
lol
vestal glen
I like JS too, but I really don't like electron. Never liked the idea of everything using its own "web" engine. I'd much rather have one central one, where I know what security patches it has...
tidal dune
It's Chromium, you can see patches, or source code if you want.

You can use others libraries like Electron for Node "Native" apps that could be less heavy on resources.
Even install a web app from Chrome to run it in a single window, but more limited in functionalities.
(Basically a standalone Chrome Tab)

little knoll
Intellisense and debuging tools that are working at each of my key input while not being helpful when I need them :p
It's probably because we are only writing some basic apps (CLI and a bit of WinForm) and that VS is more adapted to heavier/complex apps
proper gale
@little knoll intellisense is shit, get resharper.
little knoll
Yeah, I'll try it, I even have JetBrain licenses with my school so ^^'
dawn geyser
@little knoll how big are the projects you are working on ? i have no end of trouble with VS and intellisense due to one of the service reference files we have here thats around 580k lines of code, VS and Resharper really hate it
little knoll
I was just saying that probably VS would be more adapted to heavier projects and so Intellisense would be much more helpful than on a small project. ^^'

so im working on a sign up form for a site
and ive done a function that checks for invalid characters in the first name
so it outlines the box with a red border, but i would like to have a message put on the right side of the box that has a red X and says "Your name must include valid characters" or something along the lines of that
so my question is what command outputs a message in a specific location for example in that box right there ?
so what ive done so far was create a div with id "error"
and then try to set it to a certain value with the error message once function returns false
it doesnt work niether does showing an alert for some reason
so the border does turn red once i attempt to submit the field of the firstrname
dapper yarrow
How did you try to show the error message?
Display:none on the error div and jquery toggle when it returns false?
mint coral
no i didnt use jquery
im trying to use only javascript/html
function JSfirstname() {
var checkfn;
checkfn = document.getElementById("firstname").value;
var i;
var text = "/~`!@#$%^&*()_+-=0123456789'./,;";
for (i = 0; i < text.length; i++) {
if (checkfn.indexOf(text[i]) != -1) {
document.getElementById("firstname").style.border = "2px solid Red";
//document.getElementById("error").value.style.font = "bold 12px Arial";
document.getElementById("error").Value = "Hello";
return false;
}
}
return true;
this is my function so far
this line is the problem
document.getElementById("error").Value = "Hello";
ive tried creating a div under the input which has no text
and then im trying to make it have a text value with the error message
ive tried
document.getElementById("error").value
document.getElementById("error").innerHTML
document.getElementById("error").innterText
document.getElementById("error").text
and window.alert
and alert
and none of these change or do anything
dapper yarrow
Than there is an error in your js which stops the rest of the function
Right click on the page, select "inspect element" go to the "console" tab and trigger the code again. It should display errors in your js
When you're selecting the error id you do .value.style.....
Remove the .value
mint coral
the console doesnt say anything
the value.,style is a comment
it doesnt affect anything
its something i tried but i know doesnt work
dapper yarrow
Oops sorry overlooked the //
I'll be back at my office in 10 to 15 minutes. I'll be in a better position to help you from there. I'll get back to you then

alright, thanks a bunch π
mint coral
you there?
dapper yarrow
Yeah man, messing around with it in jsfiddle. Weird, can't even get an alert by only having that in the function
mint coral
exactly
i dont know why
thing is it used to alert before
but now it doesnt
dont know what im doing wrong
dapper yarrow
hmm it's weird. Have to do some normal work to so it takes a bit (well a lot) more time than usual
dapper yarrow
Weird. tried that as well. Didn't work
Anyways, a jquery example: https://jsfiddle.net/ckxrcate/32/

i havent changed anything it just started working lol

@mint coral are you stil using the getelementbyid?
dapper yarrow
I meant with a semicolon
dapper yarrow
Getelementbyid won't work on a class (wasn't being a prick, misread your answer)
Use the link above for info
dapper yarrow
Replace getelementbyid with getelementsbyclassname. Store that in a variable. It results in an array. So if you only use that classname once it's: var x = document.getelementsbyclassname("errormsgs"); x.innerHtml("hello"); should do the trick
Shit no

Question about multithreading: if I can get an exact count of the number of CPU threads available on a system dynamically, is it better to create something like an array or list of that many threads, or is it more sensible to make a queue with an unlimited number of queue-able threads?
IE a system with 8 CPU threads would have an array/list of 8 thread elements, while a queue version would be able to execute a maximum of 8 threads at any given time that would be chosen from the queue

the solution is always a plugin.
though maybe there's ide-java or something that supports building.
little knoll
With some plugins you could run your code within atom. But I don't know if there is some Java compiling plugins for Atom at this time. AtomIDE is only useful for diagnostics and advanced autocomplete.
I don't know if Visual Studio Code supports to run Java code within the editor (with the debugger) but I know for sure that it's working for JS and C# (and more through plugins)
torn bronze
Yeah that Atom IDE wont do what you need, didnt look at it properly. Best of using an actual dedicated Java IDE
little knoll
I personally use Atom for its interface and plugins (for Nodejs/PWA dev) but if you really want to run code within your editor, you should use another IDE (and wait for atom-ide to become more powerful, they recently added a shell/cmd terminal so... Probably More Soon β’ )
From what I've heard, JetBrains have a cool (but not free) Java IDE (Eclipse like). But the closest alternative to Atom is Visual Studio Code (VS Code), if it supports Java debugging (which is probably the case)

Try putting printf("\n") before the 2nd for loop?
If thats isnt what you're looking for, explore gotoxy() but I think it's pretty outdated
verbal otter
unfortunately that was not it @spark pasture
dawn geyser
im guessing your required output is a pyramid ?seperated by numbers?
well kind of a pyramid :p
verbal otter
i just have to get the asterisks under the numbers @dawn geyser
dawn geyser
yeah so gotoxy might be your best option, you have to remember where you place the 1 and basically go to the same location 1 step lower
because it looks like you dont want the output of
1
*
2
**
3
damn discord haha
@verbal otter what are the actual requirements? because "printing under the numbers" could mean a lot, you obviously have more requirements than that otherwise they would be on new lines

@verbal otter use ``` to format your code please.
Put it at the top and bottom to make a code block

Does anyone here know how to make a MP4 video stream cdn with nginx or something else?
tropic grail
Depends.
verbal otter
@dawn geyser the stars under the number and the amount of stars correlates to the number making a pyramid
tropic grail
Like this. Put code in this to format it nicely so others can read it
didnt know u could do that
tropic grail
#include "stdio.h"
int main(void) {
int numbers, stars, rows, asterisks;
int a, b;
for(numbers = 1; numbers < 7; numbers++){
a = numbers;
if( a < 6)
b=a%2;
if (b == 0){
if(numbers >= 1 && numbers < 4)
printf("\n\n%10d", numbers);
else
printf("\n\n\n%d", numbers);
}
else
printf("\t\t%d", numbers);
for(asterisks = 1; asterisks <= numbers-stars; asterisks++){
for(asterisks = 1; asterisks <= numbers; asterisks++)
printf("*");
stars++;
}
}
}
See?
tropic grail
See the ` next to the 1 key?
verbal otter
ahhhh
tropic grail
that's the one.
verbal otter
yep
tropic grail
That letter after the ``` is the language it's in, which in your case is C.
verbal otter
do you know the answer to my problem? @tropic grail
tropic grail
I don't speak C, sorry.

@verbal otter It looks like you just need a \n in front of the asterisk, no? Maybe additionally you need to add the appropriate number of spaces as well.
tropic grail
^
verbal otter
no bueno bb
ionic hull
@tropic grail do you know the answer to my problem?
soft umbra
@verbal otter you need to sort out the tabs as well. Putting /n before the * will drop it to the next line, but it won't automatically line up beneath the numbers because you haven't added tabs before the asterisks like you did for the numbers.
\n I mean lol
tropic grail
@ionic hull No, I don't do C.
verbal otter
\n will make a long line of asterisks
soft umbra
@ionic hull actually creating your own CDN is...quite a big endeavor lol
@verbal otter sorry I should have been more clear, I mean /n before the first asterisk in a group, not before each one individually
verbal otter
can you show me what your saying?
soft umbra
put printf("\n"); before your asterisks loop
verbal otter
the nested for loop or the nested nested for loop
