@last ingot Just had a look at the GitHub plans. And free tier is useless to us, with $4 a month, price would be higher than our selfhosted BitBucket, and for the UI, I have a hard time figuring out why the GitHub UI should be better than BitBucket. To me both have an equal amount of annoyances, but in parts of the UI I don't use too often to care. π
It's a virtual server, hidden beneath many others, the hosting costs of the bit bucket server is marginal, when you look at how big a share of the resources that one server takes. I'm sure if I do the actual math, the hosting is almost free. π
foggy ginkgo
Do not forget to factor in your usage of the tool. If you are a heavy user of CI/CD toolchains and you do not host and manage a Jenkins, GitLab might offer more than Bitbucket. Even with Git, GitLab offers more out of the box with protected tags and partial clones.
Companies I work with regret using Bitbucket because of its lack of features compared to the competition and the weakness of their "deployments", administration panels and basic features that should not be part of the premium plan. By the way: who ever used their "pipes", really?

Hello all, I just completed version 3.0 of my Automated / Dynamic Outlook Signature script. It's in use in quite a few places now (an older version). You set it as a logon script in Group Policy and it uses AD attributes to generate their signature and set it as their default in Outlook.
I was wondering if it would be ok to post a link to the GitHub to see if a fresh set of eyes can see other ways it can be improved or have any suggestions?

is it possible to make an auto typer that will write each letter individually into whatever the input is (google search bar for example)
having hotkeys for each line, for example if i press NUMPAD1 it wont automatically just put "google.com" it will individually put each key in
tidal tusk
does anyone know of a html5 player that can play back videos higher than 60 fps?
ashen sky
@tidal tusk Doesn't that depend on the OS and browser, more than the player? HTML5 players just use the video and audio API's available in the browser, along with the codecs the browser supports.
tidal tusk
i wouldn't think so as vimeo has a high refresh rate player
ashen sky
@tidal tusk Just made a simple test. Took a 240 fps slowmo video with my iphone, transfered the file to my computer, made a simple HTML page with just a video tag referencing the video, and it plays at 240 fps no problem. (Using chrome on windows)
tidal tusk
really?
@ashen sky
my second though is, is there a way to detect monitor refresh rate and push the proper fps?
no point in showing a 144 fps video if the user has a 60hz monitor
ashen sky
@tidal tusk Doubt it. My monitors are all 60Hz.
Also, I don't see the exact framerate, but the video is in fact played in real recording speed, not in slowmotion.
If you want, I could send you the file...
cloud knot
@tidal tusk you can't detect such things in browser
foggy ginkgo
Even with content negotiation ?
ashen sky
But the browser can do that, and restrict playback if needed.
foggy ginkgo
I mean, there are protocols to exchange information with media servers. Youtube is the prime example, as is Netflix or any other video streaming website.
cloud knot
there is literally no browser API for refresh rate information
you can only roughly measure with script like http://jsfiddle.net/rBGPk/
which prints out 143/144 fps for my 144Hz monitor
sadly it prints the same on my 60Hz monitor
ashen sky
Prints 59 on my 60 Hz monitor.
cloud knot
well it might measure the primary monitor, that is another possibility
ashen sky
Or the one with the highest refresh rate?
cloud knot
but in any case, this is browser performance measurement and not querying the specs of the actual hardware
ashen sky
Yup. Can be influenced by a slow or busy CPU....
cloud knot
so if you have something else which could slow down your framerate (let's say you calculate prime95 or fold full blast on your PC), it could measure wrong values
ashen sky
Exactly.
cloud knot
for example https://www.testufo.com/refreshrate - look at how often it says stutter warning
and that is with just discord and twitch stream running on other monitor π
elder ivy
prints 144 fps on my monitor
cloud knot
yes, but again, if you do something on your PC, it will show framerate drops often
elder ivy
there's a reason youtube is only 60 hz
ashen sky
Yeah, also just checked some javascript docs, and it seems like I have a lot of dropped frames. Makes sense on a 60 Hz monitor though.
tidal tusk
there is literally no browser API for refresh rate information
@cloud knot then how does ufotest work?
cloud knot
@tidal tusk see the code before that. it tries to pain web animation frames and measures how much can it paint
ashen sky
Seems like the video plays about 40 frames per sec, and drops the remaining 200.
tidal tusk
My phone has a 90hz refresh rate so that is accurate
cloud knot
@tidal tusk the browser of course can paint only as much frames as monitor allows it to, if not limited by other software on the PC. Thus if there is nothing else loading the CPU, browser can paint as many frames as monitor allows it to
so you measure how many frames you can paint, not what the hz of the monitor is. In ideal case it is the same value, but not everything is ideal (you learn that with coding, if you didn't yet)
tidal tusk
I'm more php than js
elder ivy
lol ufo test has obfuscated code
tidal tusk
But you see what I mean right
tidal tusk
If ufo test can determine it why can't I take the value it returns and show the corresponding video file
elder ivy
because they've taken a lot of effort to estimate fps
cloud knot
measuring monitor framerate via detection of animation performance of browser is like detecting RAM by trying to allocate various sized of RAM and see if you succeed π
@tidal tusk you can. i just say it is not bulletproof
tidal tusk
True
I think the simpler route to go with this project I'm working on is to have users fill out a profile that allows the user to specify what monitor refresh rate they have and just show the videos accordingly
elder ivy
oh this site does a MUCH better deobfuscation job https://beautifier.io/
cloud knot
you can still use the script from the jsfiddle and offer the detected value as 'default'
so if you detect 135-150 FPS, you set the default to 144Hz. 55-65 FPS, you set 60Hz. etc
tidal tusk
good idea
thanks for the fiddle
I got a friend of mine that does front end that will love this idea
he's helping me with the site
I'm handling back end
he's doing front end
foggy ginkgo
I also have an idea worth spreading if you are set to build a website or application that features video streaming.
Have you ever watched TED videos on their website?
tidal tusk
have not
backstory fyi I've been an admin of another discord for a while and we're getting pretty serious with membership
foggy ginkgo
With your web console opened, navigate to one of their videos. Example: https://www.ted.com/talks/dan_finkel_can_you_solve_the_world_s_most_evil_wizard_riddle
tidal tusk
a lot of users upload videos to sites like youtube or streamable
we figured we could build our own and have a community site
upvotes, comments sharing to other platforms
server announcements etc...
foggy ginkgo
There, you will see a lot of mp2t and aac requests that retrieve video and audio segments. TED developers implemented their video streaming platform so that the contents renders nicely on your device.
tidal tusk
very cool
foggy ginkgo
Having an Apple branded computer, my responses may vary from yours. There is one request that jumps out in that mess: https://hls.ted.com/talks/62866.m3u8?qr
This file describes the video, audio and subtitle streams the server can deliver. Your client will default on the first one, then, depending on your device and network, will decide to skip to a stream that requires more or less bandwidth.
cloud knot
in other words, HLS.
foggy ginkgo
YES! You can even find the spec online on the IETF website if you feel bored someday.
tidal tusk
Hls is something I'm new to
foggy ginkgo
In other words: I hope you will not implement this and instead choose to rely on an existing media delivery service that encodes and delivers the right video for you.
tidal tusk
But I like how it's adaptive
ashen sky
Tried measuring framerate with a video.. https://videofps.azurewebsites.net/video.html Appears to be working, but I only have 60 Hz monitors to test with. If someone with faster refresh rate would like to test, it would be appriciated. π
Feel free to comment on the code as well.

nocturne galleon
@late berry Are you looking to get into game development? All major engines are made using C++ but many offer scripting in other languages. For example the Unity engine uses a lot of C# scripting for the actual development of your game. If you're very new to programming I would suggest starting with python to learn some programming fundamentals, and once you're comfortable there all of the C++ stuff will make a lot more sense and be easier to manage. And if you're not interested in programming at all, some engines offer 'visual scripting' where you drag and drop your game logic visually instead of programming it. Unreal Engine 4 does this using Blueprints for example
@trail zealot I use a lot of python at work and am glad to help if I can, or you can dm me too if that's easier

"OrderDate": "/Date(836434800000)/",
"RequiredDate": "/Date(838854000000)/",
"ShippedDate": "/Date(837471600000)/",
"ShipVia": 3,
"Freight": 32.38,
"ShipName": "Vins et alcools Chevalier",
"ShipAddress": "59 rue de l'Abbaye",
"ShipCity": "Reims",
"ShipRegion": null,
"ShipPostalCode": "51100",
"ShipCountry": "France"
},
Does this sound reasonable?
obtuse night
could be. Thanks. Is that a common type?
ashen sky
A unix timestamp is quite common. Displaying it in milliseconds, is not quite as common. But as they all ends with 5 0s you can just divide it by 1000 before working with it, that way you have a regular unix timestamp.
But seems like javascript returns timestamps in milliseconds, which is just what I'd expect from JavaScript. π
If you are using javascript to manipulate it, this should do the trick.
obtuse night
Thank you

@ashen sky i bet the backend is java for that
tho i am not sure why the weirdos who made the backend didn't use the normal YYYY-MM-DDTHH:MI:SS+TZ:TZ notation (example: 2020-05-21T15:08:15+02:00 to say 15 hours, 8 minutes, 15 seconds at time zone +2 hours on 21st May 2020
ashen sky
Because you could just remove the / at either end, and do an eval in the string? π
But it seems more likely, that it's just the result of a silly JSON encoder, getting some other object, and does not expect anyone but itself to ever decode it, so just used a silly format.

hi guys i have a question. im trying to make a custom shell for myself in C++ .and add commands to it like:
say "hi"
and it prints hi. but i dont know how to get input and devide it by different arguments.
like imagine in my shell i add a command to make a file and its syntax is:
makefile (filename) (fileformat)
and user inputs: makefile foo dat
how do i make the application understand the syntax?
like first it says ok. the command is makefile then looks the next argument and then creates a file with the name and then sets the format from the 2nd argument
#include <iostream>
#include <string>
#include <fstream>
#include <boost/algorithm/string.hpp>
using namespace std;
using namespace boost;
class Pixie {
void sayPixie () {
cout << "Pixie - " << version << " - Prefix: " << prefix << endl << endl;
}
protected:
string prefix = "#def";
string version = "0.3";
string codename = "strong";
};
class Commands : Pixie {
public:
void commandRan(string arg) {
if (boost::iequals(arg,cmds[0])) cmdHelp();
else if(iequals(arg,cmds[1])) cmdInfo();
else wrongCmd();
}
void cmdHelp() {
cout << "\nHelp: \n";
for (int i = sizeof(cmds)/sizeof(cmds[0]); i > 0 ; i--) {
cout << cmds[i] << endl;
}
cout << endl;
}
void cmdInfo() {
cout << "\n\nVersion = > ";
cout << version << endl;
cout << "Codename ";
cout << codename << endl;
cout << endl;
}
void wrongCmd() {
cout << "\n\nCommand does not exist\n\n";
}
protected:
string cmds[2] = {"help","info"};
};
class Listener : Pixie {
public:
void listen() {
while (allowRun) {
string txtRan = input();
Commands cmd;
cmd.commandRan(txtRan);
}
}
protected:
string input() {
cout << prefix << " => ";
getline(cin,in);
return in;
}
string in;
bool allowRun = true;
};
using namespace std;
int main()
{
Pixie px;
px.sayPixie();
Listener list;
list.listen();
}```this is the code for my app
I know i can use one of the boost's library called starts_with() but idk if thats gonna work
Please no say why u use namespace or code is messy Β―\_(γ)_/Β―
shy helm
There's a few different ways to do that, and it depends how string you want to be
The simplest way would be to use the command pattern and then have a command dispatcher that matches based off the first word in the command (kind of similar to how it works with linux, but hardcoded)
So if you entered "makefile blah blah" it would look for a command named makefile and then pass it the rest of the string
For actually parsing the inputted command, again, you have a few options. The easiest would be to white-space delimitate and then you can just split it on white space. It would give you an ordered array and you could process the arguments by their expected place (i.e. you expect the file name to be at position 0, the file type to be at position 1)

nocturne galleon
@neon niche you could still get the whole input from the user like normal, but then take that input and split it into an array, linked list, vector, or whatever. That way the first item would be makefile, the second item the filename, and the third item the fileformat, etc. So you could then check what the first item is to determine the action, and so on

can someone explain what this is actually doing? if I'm not mistaken c will always be > 0 and cause an unending loop?
scenic hamlet
seems like c will be set to 0 when there are no more bytes left to read, which will happen when you hit the end of the stream
when it's called the first time, it'll read the entire stream into buf and set c to buf.Length, and on the second loop, it's already read the entire stream so buf won't be modified and c will be 0, exiting the loop
nocturne galleon
huh
but wouldn't it be 0 to begin with since thats the index where fs.Read starts?
scenic hamlet
c isn't an index, it's the number of bytes that the last Read call moved into the buffer
since the limit being passed to Read is just buf.Length, it looks to me like c will just be set to buf.Length on its first run, and then since there's no more bytes left to read, it'll be set to 0 on its second run
once its set to 0, that exits the loop
so the inner part should just get run once
nocturne galleon
hmmm
but when it goes back to check the condition, wouldn't it just read the file again?
deep scarab
no because the file stream position will be updated on every read

How do i use variables in my sql query? Im trying to get a sorting mechanism for my table using a dropdown menu, but i dont understand how i can use a php variable inside my sql query. This is my first php/MySQL project so i have no clue what im doing. I read https://stackoverflow.com/questions/7537377/how-to-include-a-php-variable-inside-a-mysql-statement but these all use INSERT and PDO's (PDO for injection risk or something but thats not a concern for me)
<?php
//Voeg inhoud header.php toe aan pagina
include "header.php";
?>
<h1>Cijfers</h1>
<p><a href="cijfer-toevoegen.php">Cijfer toevoegen</a></p>
<!--form output for tabel sortering-->
<form action="index.php" method="get">
<p><select name="sort">
<option value="DESC">Datum aflopend</option>
<option value="ASC">Datum oplopend</option>
</select></p>
<p><input type="submit" value="Sort"></p>
</form>
<?php
//Nieuwe verbinding
$conn = mysqli_connect($servername, $username, $password, $dbname);
//Var van sortering declaren
$Sorting =" '" . $_GET["sort"] . "'";
//SQL query
$sql = "SELECT * FROM cijfers ORDER BY "$Sorting"";
//SQL query door database halen
$result = mysqli_query($conn, $sql);
?>

You want to "bind" the parameter
What you're doing is quite unsafe
I would just follow the guides you find and use PDO
olive turtle
Pretty much: By setting $sorting to βwhatever; DROP TABLE cijfers β
brazen sluice
How is it unsafe? Its an option form, so no Injection risk and thats the main reason for using pdo right? @shy helm
im 5 iq so i might be wrong so idk
olive turtle
I just gave you an example

brazen sluice
isnt drop table for deleting tables?
shy helm
yeah

Im trying to sort the

so people can arbitrarily delete your tables
Ok so the user input is βwhatever; DROP TABLE cijfers β
Your code concats the two strings
"SELECT * FROM blaj ORDER BY whatever; DROP TABLE blah;"
brazen sluice
How would someone enter Drop table into this?

You dont?
shy helm
and I can also edit the HTML to make the content of the field anything I want
nope
I can just look at the destination the request is being sent to and fabricate my own request using something like Postman
olive turtle
Itβs probably just an url-encoded or some form of Post request

haha fair enough
Your SQL should work then the way it's written, no?
What issue are you encountering?

Mysqli should have binding though

Im trying to use a php var in an sql query @shy helm
and since its my first time using php i cant figure out how to make it work

That should work no?
Or
$sql = "SELECT * FROM cijfers ORDER BY {$Sorting}";
brazen sluice
Using {$sorting} it has stopped giving errors, but its not changing
olive turtle
What does your query result as? Can you output it?
brazen sluice
I forgot to do ORDER BY Date
shy helm
I don't speak the language you're using but
the ORDER BY <blank> needs to be a column name
olive turtle
Right. You end up doing order by DESC or ASC
brazen sluice
Oh does $Get output a boolean
olive turtle
But you need the column name

Oh wait i realise whats happening
olive turtle
Been a while since Iβve used βvanillaβ html but value is set to Sort for submit bit youβre getting sort? Isnβt there case sensitivity?
shy helm
Nah it just depends on the name of the field
brazen sluice
The name is what you call the output, so i use the name=sort to get $Sorting =" '" . $_GET["sort"] . "'";
While value=Sort is what the button shows when i press sort
shy helm
The name of the submit button doesn't matter...
You care about the field name of the multi-selector
olive turtle
Aight
brazen sluice
Hmm
$Sorting =" '" . $_GET["sort"] . "'";
$Sortresult = mysqli_query($conn, $Sorting);
i added a mysqli_query and now the error is gone, but its still not using the var to order
foggy ginkgo
In SQL, there are no quotes around the sort direction. The syntax is SORT field [ASC|DESC].
Also, SQL injection potential here.

Its a school assingment so injection isnt a concern, but thanks for the tip @foggy ginkgo

Hi, I'm trying to create a Flask server for a game. The server expects a json POST request and returns a json response. What is the safest way to handle the client input? I tried using escape on all the dict entries from request.get_json() but I ended up just having to cast back to a built-in type to use the data which is a bit of a hassle, and I think might defeat the purpose of escaping in the first place? Is it safe to just use the raw json and then use the below format to have pymysql handle santitize the data before running queries?
cur.execute("SELECT * FROM players WHERE player_name = %s;", (json['player_name']))
Would I then use escape() on the json response or will jsonify() sanitize any data before it's sent to the client?
Most of the data I'm expecting is generated by the client (no real user input) so the main concern is curious/malicious people trying to generate requests manually
fervent orbitBOT
Why not use something like peewee to communicate with the DB, then serve corresponding JSON to your game using Flask? You can parse out returned data pre-shipping it to the game.

Correct, Iβm Dutch @nocturne galleon

You'd be better off just generating UUIDv4s and storing them on a per-user basis. This is a fairly standard way of doing CSRF protection
But it ultimately doesn't solve the problem because I can just programmatically load your page, scrape the CSRF token, and then plug it into Postman
shy helm
How does your solution do that?
somber glacier
I'm not sure CSRF is such a problem in this situation (custom client). The only thing an attacker could do without signing in is list games that can be joined. Once they're signed in they can try and request a game be made or join an existing game. The worst they can do when in a game is just play a turn. The server is authoritative and won't allow illegal moves so they'd essentially be playing the game by post (or met with errors), without the visuals of the game to help them. I think it's more about not encouraging accessing the server in such a way and making sure they can't run malicious database code if they do. My original idea was a key/token that only valid clients know as a first level of security (which I guess could be sniffed with a decompiler) along with some sort of idempotency token for the specific action that the current player can take (which I guess is close to @last ingot 's idea). Thanks @shy helm @last ingot I'll have a bit of a think but I Think I have a better idea of how to go about it π

ah ok, i figured it was smth like that

hey guys, im having trouble with a little thingy:
im trying to insert a variable into a pointer in JavaScript
my current code looks like this obj.items.item_id.name where item_id is the variable.
all of this is json related (obj is a json file I added with const items_master = require('./vars/items_master.json');
midnight barn
You can't use dot notation with variables in JS @mellow dagger
You should use bracket notation to access the member elements if you want to do so programmatically
So obj.items[item_id].name
Also, just a small nitpick, but that isn't a pointer
rotund bramble
You should be able to do something like:
obj.forEach((item, i) => {
obj.items[i].name = newName;
});
This lets you edit the original instead of duplicating it (with map or creating a new object), which saves a little in memory (default node, which I'm assuming you're using, has a memory limit of around 1.4 GB IIRC). Of course, if you have a large JSON file that's actually over like 1 GB, you should have some method for editing in pieces with temporary files.
Also, your "newName" or whatever would be what you come up with, that was just a placeholder.
rotund bramble
Also, just a small nitpick, but that isn't a pointer
I don't think it's a small nitpick. I think it's a valid concern.
The "pointer" is actually called an "object" and are very different things. The parent should also be an object, but it mostly likely contains just a collection (array of objects).
So like:
{
"items": [
{
"property1": "value1",
"property2": "value2",
"property3": "value3",
},...
]
}
Hi guys Iβm messing with filestreams and am opening relatively large files (600MB videos) with File.OpenRead, however it seems to be really damn slow, itβs only loading in around 4 bytes each loop because thatβs the size of the buffer I made, just wondering could that be the reason itβs only doing a few kB/s? My pc has an M.2 and so my IO isnβt the problem, any ideas on how to increase the speed?
shy helm
For every read thereβs fixed overhead costs, reading something as small as 4B is going to be extremely slow because your small read time will be grossly overshadowed by the fixed costs
I.e. letβs say thereβs 50 units of fixed cost and reading each byte is 1 unit of cost (this is arbitrary for the example because I know fixed costs > small read), one of your reads is 54 units of cost, you do this 150,000,000 times and incur 8,100,000,000 units of cost
If you instead read, letβs say, 1 MB, you incur 1,000,050 cost per read, and you do it 600 times giving you 600,030,000 units of cost
@nocturne galleon hope this helps explain why itβs so slow. For reference, this concept is the amortization of fixed costs.

That code will NOT work for an random number of items.. Also I seem to remember, when I played with Java, that Java has the same "funny" thing about reading keyboard input, as C/C++ does, that you need to clear the keyboard buffer, before reading again, or else you would have some random input lurking around, and getting read. (Mostly the linebreak character caused by pressing enter.)
Also you say the code don't work, what happens when you run it?
deep scarab
that only happens when you mix formatted and unformatted input
e.g. nextInt() followed by a nextLine() will cause the nextLine() to skip
ashen sky
So the issue seems different from C/C++ then, I remember it as happening all the time there. π
Anyway, when using this online compiler/executer https://www.jdoodle.com/online-java-compiler/ The code works fine..
Except the indentation of item 4 is a little off..

@ashen sky I have a question
How can I input numbers with decimals and add $ next to the numbers into my program?

ashen sky
I'm not very familiar with java, but depending on available datatypes, a double or float is the type you want to store the values.
nocturne galleon
This is what I have so far
ashen sky
Also instead of getting someone to input the date, it's possible to just read it from the system, whenever needed.
nocturne galleon
How could I do that?
ashen sky
I think java has a date/DateTime class, that can be used. But you'll need to check the documentation for details on how.
nocturne galleon
Thanks
deep scarab
you just store them as doubles instead of ints
and to add the $ in front, just change it in the printf

Hey all! Could someone give me some feedback on my webapp? What can I do better? https://nanonews.app/

Sure! I didn't receive an email verification link, meaning I can sign up using anyone's email address without verifying it's mine. Also, you shouldn't tell me "there's no user with a specific email" when trying to password reset - that's how bots can harvest valid emails for a service.
Otherwise it works OK for what it is. The landing page could do a better job of explaining how it works though - I thought it would generate an RSS feed based on feeds I give it.
nocturne galleon
@limpid reef Thanks!! Yeah currently I don't even have password resets or any sort of verification system in place, that's coming. I'm hoping the password confirmation on the registration form will prevent the need for that until I can get it working haha.
Any suggestions for how I could better explain it? It's sort of difficult for me to think because what I have now makes sense to me, but I'm not sure how I would better describe it to someone who wasn't familiar with the system.

@elder ivy I have a flat html table that represents nested json (each row has meta-data that signifies its parent and how deep it is nested). I am trying to build the json back from the flat html table.
@tough ember pm'd me a really neat solution that worked much better than my eval function
function getParentKeys(level) {
var workingCopy = null;
var i = 0;
while (i != level) {
if (i == 0) {
workingCopy = json.get(parent_keys[0]);
} else {
workingCopy = workingCopy.get(parent_keys[i]);
}
i++;
}
return workingCopy;

I couldn't figure out a way to re-apply ".get()" to itself, so I did it using eval(), his way is much better and cleaner.

@gusty girder not really a recursive solution though lol
gusty girder
Perhaps my problem was not ever recursive in nature in the first place Λ^
elder ivy
I mean you can solve it using recursion. guess that was a red herring
gusty girder
Not as much for you as much it was for me. I thought it could only be solved by recursion because I needed to apply itself on its result, but as Lobfil (and myself) demonstrated, a for loop was good enough for that.
elder ivy
I was gonna say a lot of these homework like questions actually require you to use a certain programming concept in order to accomplish it. asking someone to write something in both iterative and recursive ways is a good example
shy helm
All problems that are solvable recursively are solvable iteratively, and vice-versa
elder ivy
it's may possible to write but not elegant
gusty girder
I'm gonna save both of those replies. That like, lit a lightbulb in my head lol.
Can any of you offer a recursive solution to the problem so I can compare? I just needed to solve it, it didn't really matter how, but I'm curious how a recursive version would look.
elder ivy
Since your data structure doesn't have levels counted for you inside it. You probably have to pass in the current level into the function to count
Curious though. Why do you need to stop at a certain level
shy helm
You probably can do this with pure structural recursion, not sure if I specifically get what your code does, there's a number of undefined variables
gusty girder
Since y'all curious:
I have a flat html table
row (key: value)
row (key: novalue)
row (key: value)
row (key: value)
that represents a nested json
key: value
key: { key: value, key:value }
(I know it's not actually written like that, it's for visual purposes, so you understand what it represents)
What I'm doing is I'm creating actual json from the flat table.
So I create an empty javascript Map(), and go row by row, adding key:value pairs.
Of course, in case of the second row, when it has no value, but is actually the parent of row 3 and 4, I create an empty map() for its value, but then when I reach row3, I can't access the initial map anymore, I need to access the map inside the map to put the values inside
perhaps this screenshot will illustrate it better
The html table (on the left) is actually a flat structure. The visual nesting that you see is purely that - visual with a margin-left.
What I needed is to create actual json that is nested from that flat structure.
gusty girder
It works tho Λ^ (but fucks up when I try to access nested arrays)
shy helm
Recursion should give you a very easy solution for that
elder ivy
I mean there's some weird parts to this structure you realize @gusty girder
key12 is repeated three times for instance
gusty girder
it's on a different nested level though, json specs allows for it
elder ivy
and it's not obvious what you actually want at the top
shy helm
It's basically just
jsonify(root) {
json : Map
for child in root:
if (child.hasChildren())
json[child.id] = jsonify(child);
else
json[child.id] = child.data
return json
}
yes of course it does. but how flat do you want it
I mean you can construct unique keys recursively downward too
gusty girder
No I don't want it flat. I WANT it nested. My SOURCE is flat The table on the left. It's flat.
elder ivy
oh lol
gusty girder
you can see in my html, I have the metadata to figure out which belongs to what parent
but the structure is flat, and I use the metadata to generate the actual json
shy helm
The pseudo code I gave you above should be correct--you'll just have to modify it to work specifically with the data format you have
gusty girder
Thanks, I'll try it. I basically just use the innerText values from each cell (or values in case it's an input)
shy helm
i.e. you need to change it to support the initial flat structure, which shouldn't be too hard--use the comma separated list of key names to simulate depth
gusty girder
json : Map What does this do?
elder ivy
it's pseudo code
shy helm
though my code does assume that they are presented in order, if they're not it will break
It's just a type def in pseudo code
elder ivy
yeah I was gonna say this is just iterating straight down a flat table and then creating your nested object along the way
gusty girder
yeah I was gonna say this is just iterating straight down a flat table and then creating your nested object along the way
that's what I do now, just with a for loop.
shy helm
How familiar are you with recursion?
gusty girder
Not very much at all. I pretty much used it for the first time ever about 3 weeks ago
shy helm
Ah, you may have a hard time adopting my pseudo to work for an initial flat structure then
elder ivy
I mean that the code above only gets you the object at a certain level. I'm saying you can just build the entire object walking through the table once through
shy helm
But if you want to try it anyway and want a hint on the direction, you should be able to do it using pure structural recursion (to give you something to Google)
Yeah, the pseudo code I gave would turn an entire nested table into a nested map
elder ivy
assuming that it's nested by increase in level strictly (ie that the parent is the previous level - 1 parent)
gusty girder
That wouldn't work, sometimes a row is level 2 or 3, and the next row is back to 0
shy helm
that's why you should use the keys instead of the level
gusty girder
I can get level from the keys, just comme-delimited-array.pop().length() but I get what you're saying.
shy helm
you can, the length of the comma split string array is the level
and split-arr[n -1] is your current key, split-arr[n-2] is your parent (n being the length of the arr), special condition for n = 1 where the parent is root
gusty girder
It just seems faster/easier to store it separately, as I only generate the table once (php when I load the page), but I rebuild the array many times when the user edits values etc
so I perform less "calculations" as I can simply access level information directly
shy helm
yeah, the issue is you can't figure out where you are in the hierarchy using just level data, you need the keys too
elder ivy
lol if you're going to use the keys then you're going to have a bad time at the bottom row aren't you
keys="key10,1"
shy helm
oof
gusty girder
yeah, key10 is an array so it automatically uses 0,1,2 for "keys" but since it's an array it doesn't actually have any
gusty girder
yea no problem (narrator: but actually it was a problem, but I'll look into it)
shy helm
Just a suggestion, otherwise processing any of the keys will be basically impossible since you wont be able to ensure that splitting the string gives you the actual keys
gusty girder
well isn't 0,1,2 technically the correct keys for an array?
elder ivy
I mean the other part is why is your UI different than the structure used to represent it
you might as well just create it in the way it's supposed to look
shy helm
well isn't 0,1,2 technically the correct keys for an array?
@gusty girder ye, just don't comma separate the index with the key name
gusty girder
I mean the other part is why is your UI different than the structure used to represent it
How would you representa json editorstructured data in html without a table?
elder ivy
lol I mean you can blindly assume that intermediate levels exist
and blindly create keys/levels along the way
shy helm
I mean the other part is why is your UI different than the structure used to represent it
this is also a good point, you probably could nest your TRs and use a special inner CSS class to make them indent
elder ivy
I mean it's also a matter of reordering, collapsing etc. nested html makes that a lot easier
gusty girder
but a table doesn't really support nesting (it does but ugly af with double borders and other problems)
I would have to use a list for that
and list has the "vertical" problem
how I make the columns match up
Like I'm not averse to using something better, but I couldn't figure out anything better for myself. I looked at other json editors, and they all use what amounts to a table
example
so that's what I went with - why reinvent the wheel.
shy helm
table rows can nest fine, you just have to change the CSS
if you use a special inner CSS class you can remove the extra borders and fix the other stuff

Hi I have a question. Will a reaction collector stop if the message the reaction collector was on is deleted?
In discordjs
meager turtle
Would anyone be able to point me in the right direction to find a reliable and trustworthy web developer with experience in things like CDNs and NGINX? I'm pretty comfortable with the frontend stuff of webdev but the backend I'll definitely need to find a professional to help me out. Would prefer a referral to somebody rather than just hiring somebody who I don't have a connection to.
shy helm
What region are you in?
meager turtle
United States, Northeast
shy helm
idk if this is the best place to ask though tbh
hmmm
Like outside of me recommending people I know, I can't really give you an objective recommendation haha
meager turtle
I figured not, I just enjoy Linus' community he built and I'd respect y'alls advice and opinions.
I'm open to personal recommendations too. I'm looking for POC and/or progressive minds really.
shy helm
What kind of backend work is it? If it's not super custom you might be able to go with a relatively standard solution
wordpress/etc
meager turtle
I'd prefer to avoid using a CMS or frameworks if possible, I want it to be lightweight and efficient (fairly custom I suppose)
I know it's a huge ask...but the cause is worth the effort (and my own $) imo
shy helm
Does it actually need a backend? Like, is this something users are going to be interacting with directly to do stuff?
Or is the backend just to serve content to the front end?
meager turtle
Yes, I'll need quite a bit of content and user protection.
shy helm
ahh
meager turtle
I mean ultimately I want the frontend to be as simple as possible, but the backend I want sturdy and secure and efficient
shy helm
Yeah fair enough
TBH even if you hire a dev they'll probably end up using a backend CMS
meager turtle
Yeah, I realize thats kinda the norm these days :/
shy helm
Full custom just isn't really worth it now a days
meager turtle
but I'm hoping I can find a savant to work alongside ahahah
shy helm
Unless it's supppper custom
like you're doing stuff that's out there
the issue you'll find though is full custom has higher maintenance requirements
meager turtle
I'm not completely discounting using frameworks, I just want to make sure the site's content and users are well protected.
shy helm
finding new people to maintain it is a PITA tpp
WordPress has gotten farrr better than it used to be
not perfect but
meager turtle
If somebody can convince me that their CMS and framework is secure and efficient I'd be willing to go that route.
shy helm
Well, you just do things like security through depth
if you're really concerned about the CMS being vulnerable
proxy the website through something like CloudFlare
restrict access to admin sections to certain IP addresses if you're super concerned
meager turtle
Oh yeah I'm definitely looking to utilize CDNs as much as possible, I don't have the money to fund a raw metal server structure.
thats not a bad idea for initial security though
I appreciate the info a lot!
meager turtle
Thanks π security and authenticity is going to be a huge point of interest for me and the business
foggy ginkgo
@meager turtle CMSs are not all heavy -unlike those from ibexa *cough* *cough*-. The core idea of a CMS is to⦠well manage content. Therefore, presentation can be delegated to other applications that would retrieve content from the CMS. Two examples: Contentful and Strapi.
Depending on what you wish to build, you might have to consider your requirements before choosing any tool. Basically, how much does your application need to be resilient, cost-efficient, maintenance-free, secure, performant?
This also applies to NginX or the CDN you will choose: what is essential, what you can add. Do you need it to be flexible, an industry-leader� See what I mean?
meager turtle
Thank you @foggy ginkgo ! I appreciate that information. My requirements are definitely a bit specific to my case, I'd love for secure, resilient, and cost-efficient CMS most of all. My only concerns with CMS' are the security flaws I've witnessed in some scenarios. Obviously it's not the norm that they are unsecure but I just want to basically make damn sure mine will be, especially if I'm storing important or personal user data that I want to keep 100% private.
honest hamlet
does anyone know a good http server vulnerability/security scanner site?
foggy ginkgo
@meager turtle Unfortunately, I can only provide help with AWS when it comes to choosing the right service and AWS might be too expensive in your case.
You would need:
- a scalable object storage (S3 / Backblaze) for your content. If you are conservative, your CDN could optimize and deliver static assets. Otherwise, go crazy!
- some session storage, preferably a key-value store like Redis;
- a scalable CMS API;
- a NoSQL database or multiple relational ones in a Master-Standby configuration or Master-Standby-Read configuration;
- a domain name and some SSL certificates.
Your scalable object storage can also host your frontend application and your CDN can also deliver it. Some basic level of security can be achieved at the network level by not exposing your object storage and your database to the Internet. And by only exposing what the user needs to see and nothing more. Easy you say?
Now, you can decide on how and where you will host this and whether or not you need all these services. This is a baseline but sometimes less is more π
Oh, and another free tip: automate everything. Yes, even infrastructure provisioning and deprovisioning can be automated.
meager turtle
Dude...that is an amazing amount of useful information for me. I greatly appreciate it. I'll look into all of these things.
β€οΈ
shy helm
Keep in mind AWS is veryyyy expensive for bandwidth
There's a reason why we don't use it for LTT
meager turtle
Yeah I'd prefer not to use a CDN that is run by a potential competitor. Don't want to risk them throttling or disabling my access for whatever reasons.
A friend told me that even if they did throttle me there wouldn't be an easy way to get proof.
I'll most likely go with whichever service is most unbiased to the actual content, because I want to allow adult content as well.
foggy ginkgo
Here is a fringe idea that I have never actually experimented with but that tempted me for a while: Multi-CDN.
Let's think about it: your assets will probably be delivered by a domain like static.mywebsite.tld. What if you could, with some telemetry sprinkles, use multiple domains for your CDNs and shift in real time towards the most efficient in a certain region and for certain types of contents?
Or randomly choose which CDN will deliver your assets. They all have the same access to your static contents, right?
Anyway, going without a CDN is hardly an option today, I fear.
elder ivy
o.O that's what a CDN is supposed to do
unless I'm not understanding something, it's literally in the name
multiple CDNs would get annoying with CORS anyhow
foggy ginkgo
I do not see how. Provided they all point to the same vhost or set of vhosts with similar configurations π
Then your CORS issue is a matter of handling OPTIONS and adding headers at the vhost level.
shy helm
CORS is on a domain not IP basis
iirc most CDNs let you use custom domains and use anycast IPs for serving, you would just have to give the user the right anycast IP based off GEO location
But yeah, what Blue said, the whole point of a CDN is to do all this for you...
elder ivy
depends if you want common libraries being cached or not across other websites too
shy helm
true, but if you do that you should just pick the most popular CDN for that library, ignoring local performance
Since that would give you the highest chance of it already being cached in the user's browser
meager turtle
These sound like great ideas! Interesting to see the discussion about it.
iirc I read about how Netflix does their hosting and they basically use a bunch of raw metal servers distributed in various locations usually with the support of local ISPs. So it's a similar mentality to using multiple CDNs that are located in different parts of the world.
Because ideally you want the content hosted/streamed from the nearest provider to your end user.
That could've been dated information, but I'm pretty sure that's how they used to function.
shy helm
Actually they use AWS largely
they do have custom cacheing servers that they colocate with local ISPs though to improve performance/alleviate load, etc
meager turtle
Ah interesting!
zenith junco
do anyone here knows about TCP/UDP sockets?
I neeed to send large chunks of data several times a second
~300KB, 20/30Hz
Is it possible? I alredy tried, with a server/client application, and is likely to loose the start of the buffer
In the client I always recieve only part of the buffer, always the ending part
And sometimes the whole buffer
ashen sky
Do you close the connection after each transmission?
ashen sky
Perhaps the issue is, that the OS can not handle the data at the network layer, fast enough? Or the OS has too small buffers..
You would only do that, if you were inexperienced, and I've seen it done, by people not understanding why performance suffers. π
zenith junco
I think if the buffer is too small the OS sends the data in small packets
ashen sky
If it possible for your application to just chop the data into smaller chunks, and reassemble on reception?
zenith junco
well, it would be difficult
ashen sky
As I see it, your payload would ideally be small enough to fit in single packets. Also are you using UDP or TCP? Is the network stable? Or could the data become lost in transit?
zenith junco
TCP, and network is stable
and I'm sending the whole 300KB buffer in a single send() operation
so I think it cannot fit into a single packet
ashen sky
Well, that shouldn't be a problem, with TCP it should just be split and reassembled on reception, by the OS, and fed as a single stream to your application. Only thing your application needs to do, is to not assume all data is available when reading from the stream, but it should be handed over from the OS in the right order, without loss.
zenith junco
thats is exactly what I was expecting, but I loosing data
with a single client connected it seems like the stream is very stable, failing just sometimes
but with 2 clients, it goes very wrong
ashen sky
How do you read the data? Waiting for a "Data available" flag, then reading what's there, and repeats until your get your "End of data" mark?
zenith junco
with recv(), that handles it for me I think
It takes new data in the buffer and waits until reaches end of data
but the new data in buffer could be incomplete, but always containing the end of the buffer
ashen sky
The way I read the man page, it seems like it would just read whatever is available, but I'm not exactly sure, what will be regarded as a message.
Eg, if there's a short delay before part of the data is received, will that be regarded as the end of the data?
zenith junco
I don't think so
But recv() is a blocking method, so it waits until reaches end of message
I guess
Its for a uncompressed video streaming application, I can show how it looks visually
(with 2 clients)
ashen sky
Have you checked that you are not, by accident, making the buffer you store the data in, too small?
Hmm... Why not use RTP for that?
zenith junco
Have you checked that you are not, by accident, making the buffer you store the data in, too small?
@ashen sky no, the server and client buffers are exactly the same size, and if that was the issue, I would get a acces violation, or the data would be staticly lost, but the buffers that I get are of variable sizes
Hmm... Why not use RTP for that?
@ashen sky RTP? I don't know much about it
(demo with 2 clients)
ashen sky
RTP is basis for basicly every video and audio streaming application.
ashen sky
Here's a good place to start. https://en.wikipedia.org/wiki/Real-time_Transport_Protocol
zenith junco
Thanks for your help and info!
ashen sky
But for RTP my experience is more on the user part. (Work at a VoIP provider)
zenith junco
it seems like is connection less
I really would like a normal client/server with established links
it seems like is connection less
@zenith junco like UDP, because RTP seems like it runs un top of UDP?
ashen sky
Well, if you split the library, I'm sure you can just change the transport to TCP if you like. Also I think I've seen RTP over TCP implementations. But for streaming, TCP is not really great, at that rate..
zenith junco
but, I would not have the same problem with RTP over TCP?
It is still TCP
but RTP splits all the data and handles it for me?
ashen sky
If you find an RTP library.. But also keep in mind, that TCP connections uses resources on the server while the connection is running, UDP don't. Also with RTP and UDP you can multicast the stream, and save both network bandwidth, and system resources.
If it's just a learning project, I'd say do what you find fun, but if it's to be used for something serious, I'd say switch to RTP and UDP for the stream, and implement multicast if it's only to be used on an internal network, do control commands over TCP if you like, but UDP is better unless there's a good reason to keep the connection open.
ashen sky
RTSP makes sense to have implemented as well. π
zenith junco
Yes, but I have a raw buffer of pixels not a JPEG frame, or a MPEG chunk
ashen sky
Hmm.. Been thinking a little, how does resource usage look on the server when you connect client number 2? (I've understood that it mostly works fine with one 2 client, but fails a lot when connecting the 2nd) Does it struggle with CPU to capture the image?
zenith junco
it just consumes 50% of CPU time, with 1 cient and 2
zenith junco
320x240
Unless it's a pi.
@ashen sky Its not a raspi, but is not the heck of a lot of a computer
Is 2c/2t
ashen sky
But should still be able to handle 320x240 with less CPU.
zenith junco
Totally, but I do a while (cond) to wait till the new camera frame is in the buffer
ashen sky
Don't the capture driver have events for that purpose?
zenith junco
nop, is C style
you call a function to start the image capture, and polled waiting till the pixels are available in the buffer
ashen sky
Well, I suppose you should see what you can do to optimize performance, as that might be the entire problem.
zenith junco
Hmm
ashen sky
Eg. it usually takes 10 ms for the image to be ready, make the loop sleep for 10 ms before checking.
zenith junco
Ok
ashen sky
Adjust 10 to whatever fits the real world. A constant loop, with no sleeping, is asking for trouble. Whenever you call sleep, the CPU get a chance to process other things, and your application will consume less of it.
zenith junco
while (isCaptureDone(device) == 0) { std::this_thread::sleep_for(std::chrono::milliseconds(10)); }
oh thats a lot less CPU time
ashen sky
Something like that.. But if you know how long it takes for the frame to be ready, set the time to about that.
zenith junco
now is 8-10%
ashen sky
Hehe.. I've made the same mistake before. That was C# though...
zenith junco
Same
ashen sky
Also, while you're in the loop, network traffic is not processed..
zenith junco
I know that
Wait, i'm going to try with my 2 clients
nah, still the same
but the first client gets whole frames at 4/5fps and the 2nd client gets incomplet frames at 15fps
ashen sky
Do you have a similar loop on the clients, that could be optimized?
What if you lower the rate to 1 fps? Make that work flawlessly, and work up from there?
zenith junco
this is the whole loo
loop
while (true) {
doCapture(device);
while (isCaptureDone(device) == 0) { std::this_thread::sleep_for(std::chrono::milliseconds(10)); }
memset(buff, 0, buffSize);
writeIntToBuff(cap.mWidth, 0 * 4, buff);
writeIntToBuff(cap.mHeight, 1 * 4, buff);
for (int i = 0; i < cap.mWidth * cap.mHeight; i++) {
writeIntToBuff(cap.mTargetBuf[i], (i * sizeof(int)) + (2 * sizeof(int)), buff);
}
/*for (int i = 0; i < 8; i++) {
for (int j = 0; j < 4; j++) {
std::cout << (int)buff[(i * 4) + j] << " ";
}
std::cout << std::endl;
}*/
// Send buffer to all clients
for (int i = 0; i < clients.size(); i++) {
threadPool.push_back(std::thread(sender, clients[i], buff, buffSize));
//send(clients[i], (char*)buff, buffSize, 0);
}
for (auto& t : threadPool) {
if (t.joinable())
t.join();
}
threadPool.clear();
}
void sender(SOCKET s, uint8_t *buff, int buffSize) {
send(s, (char*)buff, buffSize, 0);
}
I create a thread for each send() operation
ashen sky
Multi threading.. Ouch.. π
zenith junco
But I think thats wrong
What if I just do this
for (int i = 0; i < clients.size(); i++) {
send(clients[i], (char*)buff, buffSize, 0);
}
I don't think it's entirely wrong.. But threads are usually causing a lot of fun problems. π
zenith junco
I tested to have a thread that asyncly updates the buffer and a thread for every client that sends the buffer at a fixed rate
That didn't work
Was very unstable just for 1 client
I just put a std::this_thread::sleep_for(std::chrono::milliseconds(1000)); at the end of the loop
ashen sky
But I think I'd make the threads do more.. Eg. Fire a thread when a new client connects, to handle connection setup, and data transfer. When a new frame is ready, signal all threads that a new frame is ready, and have the threads process the frames.
Consumes a bit more memory and CPU, but should be easier to debug. (Eg. all images transfered looks wrong in exactly the same way, it's a capture problem, only a single looks wrong, transmission problem etc. )
zenith junco
I'm not profresional with weird std mutex async and futures so, I don't really know how to signal the threads
ashen sky
Neither am I, I mainly use PHP, and recently python.. Quite different. π
And hardly ever with threads.
zenith junco
So it seems like at 1fps it runs great! But at what cost, 1fps
I'm going to wait just 100ms
ashen sky
Try increasing the rate, until it fails..
zenith junco
100ms
now is running 7/8fps
and is much better, the image is always stable in the 1st client and almost always stable too in th 2nd client
what if I do a small sleep in the client loop?
Like 20ms or so
What if I just do this
for (int i = 0; i < clients.size(); i++) { send(clients[i], (char*)buff, buffSize, 0); }
@zenith junco (this loop)
now is running 5fps, very low CPU usage, 230x240
Just failing sometimes
Sporadically
ashen sky
Well, try, see what happens.. π
Programming is mostly planning and trial and error, for casual and non-critical projects. (Critical like spacecraft control, avionics, etc)
zenith junco
hahah
I have found that when it fails, the client recieves actually more data than expected
(And sometimes less)
ashen sky
Perhaps you get two frames in one packet?
zenith junco
So I think that the losses and unexpected behaviours is just the OSs trying to break and build the buffers and waiting for all the litte pieces in packets
Perhaps you get two frames in one packet?
@ashen sky 2 frames would be 600KB, I don't think that fits in a single packet, are you refering to a send() operation?
ashen sky
No, I'm thinking that you might get the data mixed up, because client and server are not syncronized. The client may have 1 1/2 frame available when you ask for the data from the socket.
zenith junco
probably
now with the sleep_for() is much better, even with 3 clients
but the framerate is reduced
ashen sky
Yeah. But I suppose for surveilence cameras a framerate between 5 and 10 would be good enough.

UDP question: do every sendto need to be followed by recvfrom?
round dome
no
zenith junco
That makes sense
zenith junco
Remember my uncompressed video stream server/client?
I implemented UDP multicasting (simply with the broadcast address)
But with UDP I can't just send a whole 300KB buffer, so I send line by line ~1290 bytes per line.
But there are quite a lot of packet loss, that is half solved just with a delay of microseconds in the server, but that makes the video very low in framerate, and there is still a litte bit of packet loss.

Best to ask a tech community first.
shy helm
AWS or GCP for their free tier
Youβll pay some money for data transit, but assuming youβre not moving that much traffic (like say only a few GB outbound) youβll pay pennies
You probably could use azure too I assume they have a free tier
verbal herald
Thank you, Im a little bit new to this so would it be the Amazon Compute? I just need to be able to host a Node Discord.js Bot and a MongoDB database on it
foggy ginkgo
On AWS, you will be able to get one t2.micro EC2 (Elastic Compute Cloud) instance for free for one year. With 30GiB of block storage and 1GB of outbound trafic per month for free.
To learn more about their Free tier: https://aws.amazon.com/free/
Is it enough for a small bot? For moderate usage, it will do. And nothing prevents you from hosting your website on some other solution such as GitHub pages.
verbal herald
I really dont know. Im really concerned for my computers sanity cause i want to add music but dont wanna risk killing it more now that im going to be over 100 guilds soon.
And that data storage should be find for awhile, i have a lot more data stored now then i will when i migrate
foggy ginkgo
Well then you might need a different approach. If you are not against vendor lock-in, they have a NoSQL database called DynamoDB with a good enough free tier.
Then you could either setup one EC2 for your music bot, play with their autoscaling and load balancing solutions or find a way to Dockerize it and run it on Elastic Container Service. Elastic Kubernetes Service would work as well but is a severe overkill in my opinion.
verbal herald
But will i be able to open both on a free tier?
Its not a big problem if i cant just would be amazing if i could
foggy ginkgo
Any of these solutions would work. It depends how deep you want to commit to AWS from the start and your compute model.
Just be aware of all the hidden costs. You should consider visiting the pages of the services you wish to use to read about their pricing. Before using them, preferably.
verbal herald
Yeah, thats my main concern at any of the solutions ive looked at. I looked at Digital Ocean and Oxide Hosting and they just seem to either be too good or missing important things in a bot with very limited specs

Quick question, is it wrong to re-write a piece of software your company developed in your own time (as a learning exercise only)? My company uses a piece of software which i am wanting to convert to being scalable and using .net core, but not sure of the ethics of basically copying the idea for personal use
shy helm
As long as you don't do it the same way you're fine generally, even if it's for commercial purposes (this is not legal advice)
rebuilding something functionally identical for a learning exercise is probably entirely fine too
elder ivy
usually what happens is that the company owns your software regardless of when you wrote it as long as you're employed
it's not "wrong" but all code you write is theirs anyhow (within their industry)
shy helm
i.e. if my company makes widgets and I decide I want to practice widget making, so I recode their widget 9000 as a personal project (no selling it or anything), there should be zero issue
usually what happens is that the company owns your software regardless of when you wrote it as long as you're employed
@elder ivy no, most courts have ruled this not legal and many jurisdictions have laws specifically prohibiting this

I've signed 4 different non-competes for software jobs in the past few year--none of them cover personal learning projects
elder ivy
I mean going to market and uploading to github are two different things too lol
shy helm
Heck, I've yet to hear any of my friends complain that their noncompetes cover personal projects

@elder ivy dont go there. i uploaded my coursework for my apprenticeship to my private github and the apprenticeship provider flipped out
elder ivy
lol that falls into the territory of who owns your work for school too. it's all non sense
IP laws are silly, but if what ever you write never sees the light of day it's fine

another question, if you upload to private github repo, does that mean github has the rights to it?
shy helm
No
elder ivy
I'd probably self host just to be safe. I mean there has been breaches and what not from online hosts from time to time
if it's proprietary knowledge etc

another question, if you upload to private github repo, does that mean github has the rights to it?
@obtuse night im not worried about it, its just something i thought of just then
elder ivy
github doesn't ever own the rights to the stuff you upload as far as I know
shy helm
Using GitHub you basically only give them the rights they need to share your content per. your settings
I.E. if you make it public you give them the right to reproduce your code
As required for them to actually display it to someone else
TOS dictates they assert no right beyond whatβs required for them to perform their service to you

Im having an issue right now where I'm trying to serve an image from a php file and when I do
<img src="localhost:80/path/to/my/serve.php?picture_id=1234567890"/>
it doesn't show the image but if I put localhost:80/path/to/my/serve.php?picture_id=1234567890 in my browser directly it does load an image
any ideas?

@dense marten You should add the protocol before the domain. Since this domain is localhost, "http://" or "//" would both work in your case.
dense marten
Thanks! I can't believe I overlooked that
dense marten
I have another question now, so now that I have it working as http://localhost:80/path/to/my/serve.php?picture_id=1234567890 is there a way for me to configure Apaches rewrite engine so that while I have http://localhost:80/path/to/my/serve.php?picture_id=1234567890 as my img src when you right click on the image to get image url it says that it's actually http://localhost:80/images/1234567890
The reason why is because I added token (it's what document.cookie returns) as a parameter to the url to do permission checks on if a user can view an image and I don't think I want to expose the token in the URL
foggy ginkgo
You would need an Apache rewrite rule. Here is a candidate for your query:
RewriteEngine On
RewriteRule ^/images/([0-9]*)$ /path/to/my/serve.php?picture_id=$1 [L]
Documentation: http://httpd.apache.org/docs/current/mod/mod_rewrite.html
dense marten
What I tried was
RewriteEngine on
RewriteRule ^path/to/serve.php?Reason=GetImages=picture_id=$1&token=$2 images/$1 [NC]
did I get it backwards lol

You were also missing the (capture regions) of the regex. You were on the right path with your research, though π

I don't know if this breaks #6 or #16, but i updated to iOS 14 and my banking app broke (intentionally, they say beta versions are insecure). I'm gonna try to reverse-engineer the app to disable that check. Any pointers maybe?
(pointers. hehe)

You might be forfeiting certain insurances they have against theft if you do that
At least I suspect that would be the case in Canada

Hi.. I was wondering is it possible to dispatch multiple trained ML models for multiple frames at once in GPU... I am trying to anaylze a video of an input I already have model decided I just need to know if there is any way possible to not call the model per frame at a time
elder ivy
you might get your online banking privileges revoked. or easier yet they just kick you out as a client

I have a .net core worker service, and am wanting to add a single api endpoint to it without converting it all over to asp.net. Is there a way of doing this?

void ispF();

int main(){
double g;
double m1;
double m2;
double DeltaV;
ispF();
return(0);
}

void ispF(){
float isp;
printf("Enter the isp: ");
scanf("%f ", &isp);
printf("%f", isp);
}``` everything works fine till after this line ```scanf("%f ", &isp);```c btw
ive also had difficulties when using doubles. it wuldn't print anything or scan it. i was using the %lf tag
oof
it was the space at the end heck

hi guys, I have a quite simple question probably: in C++, what data type do normal numbers have? Like for example "arr[3];", what data type is the 3? a size_t or an int or something else?
shy helm
It depends haha
IIRC it's implementation defined
when you have a 3 there in your code, it's a constant though, it's not really stored as a variable
but for example, if you have const int n = 5, it's likely stored as an int constant in the read-only part of the compiled output
worthy dirge
That 3 is a int literal, and then implicitly converted to pointer arithmetics for array indexing
For your own class tho, you can define operator[] to accept any type
Not sure about literal type? You can do std::cout<<typeid(3).name();
nocturne galleon
anyone know how to make P2P connections in unity?
ideally with steamworks but if not i dont mind
nocturne crypt
@supple abyss if you're referring to the index of an array, it depends on the arcitecture
for example on x86_64 on a POSIX compliant system it'll be unsigned long, on an arduino it'll be a unsigned short (int in arduino is a 16 bit number :/)
on Windows, it's defined in words which may or may not be unsigned long on an x86_64 system
various 64 bit ARM implementations usually side with unsigned long

Anyone understand what amazons honey code is exactly? Seems like visual studio but more simple? Idk
Is it basically like VS and android studio?
foggy ginkgo
It is a no-code software editor that is similar to Retool. There is a very interesting discussion going on on Hacker News about Amazon Honeycode: https://news.ycombinator.com/item?id=23633110

Also the "equivalent" service for VS would be AWS Cloud9: https://aws.amazon.com/cloud9/
