development

[hollow basalt]

which is a fancy way of saying inside the node itself

[midnight wind]

oh yeah you need to exit node terminal

CTRL - D I think

or CTRL - C

when i type node app.js

[midnight wind]

did you install discord.js

[next igloo]

i beleive i had but i will double check

[hollow basalt]

how did you installed it

[next igloo]

npm discord.js

[midnight wind]

in that folder?

[hollow basalt]

[next igloo]

something like that in command prompt

[midnight wind]

is it in package.json?

[next igloo]

hmm thats why

i used the command prompt you get from typing in windows search

[midnight wind]

yeah, npm is folder specific

will create node_modules folder

[hollow basalt]

it probs isntalled in
C:\Users\ericr\node_modules

[midnight wind]

yeah

[next igloo]

it is

[hollow basalt]

tbf, that's the best practice

[midnight wind]

yeah I guess

[next igloo]

how can i get discord.js installed to the folder then?

[midnight wind]

just npm install discord.js in that folder

[next igloo]

typed it in cmd

and it gave the module not found error again

[hollow basalt]

screenshot in cmd?

when you installed it

[hollow basalt]

have you tried saving app,js then running it again

[next igloo]

how can i check if discord.js was installed correctly

[hollow basalt]

actually inpsect the node_modules fikder

or use

npm list

[next igloo]

C:\Users\ericr\Documents\nodehttp>npm list
nodehttp@1.0.0 C:\Users\ericr\Documents\nodehttp

[hollow basalt]

looks good

[midnight wind]

is your file saved?

[hollow basalt]

i said that lel

[midnight wind]

yeah ik

idk if he did it

[next igloo]

yes

[hollow basalt]

cause the file probably has token

[next igloo]

i removed the line that had the token

and now when i type node app.js it freezes

[midnight wind]

yeah

[hollow basalt]

that's actually a good sign

[midnight wind]

wait show the code

[next igloo]

const client = new Discord.Client();

client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}!`)
});```

[midnight wind]

did you create discord token?

[next igloo]

i did

[hollow basalt]

which is where

[next igloo]

but when i typed node app.js it would give me an error

even i put quotes around the toekn

so i removed it

[hollow basalt]

[midnight wind]

ok then in client.login("token here");

[hollow basalt]

hardcoded

[midnight wind]

is it the right token

a bot token

not a app token

[next igloo]

it was the wrong token

[hollow basalt]

token't

[midnight wind]

now, don't hardcode it

get it out of there

[next igloo]

i put in the correct token

for the bot and not the app

i got it to work

thanks for the help

const Discord = require("discord.js");
const client = new Discord.Client();
const token = require("./token.js");


client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}!`)
});

client.on(`message`, msg => {

  var response = msg,
  prefix = "$",
  string,
  number,
  channel;

var list = {
  array: [ 
["a"],
["b"],
["c"]
]
}

if (response.charAt(0) == prefix) {
  string = response.slice(1, response.length).toLowerCase();
}

if (string == "reset") {
  msg.reply("Reset Bot");
} else if (string == "guide") {
  msg.reply("Channel Guide");
} else if (string == "current") {
  msg.reply("Current Channel");
} else if (string == "cycle") {
  msg.reply("Cycle Channel");
} else if (string == "previous") {
  msg.reply("Previous Channel");
} else if (string == "about") {
  msg.reply("About Bot");
} else if (string.includes("channel: ") && (string.length == 10 || string.length == 11)) {
  number = Number(string.slice(9, response.length)) - 1;
  channel = list.array[number]
  msg.reply("mb play " + channel)
  } else {
  msg.reply("Syntax Error");
}

});

client.login(token);

i get at error that (response.charAt(0) is not a function

the script works in normal javascript

except msg.reply is alert

and client message is prompt

[midnight wind]

that means charAt() is not a function

you can use a debugger and see all properties of response

[next igloo]

is there a function that does the same job?

[midnight wind]

¯_(ツ)_/¯

google

[hollow basalt]

lel

remember #development isn't community debugger

[midnight wind]

asking is my last resort

I google everywhere

[hollow basalt]

this is what I want

people learn by researching

[next igloo]

i found the problem

var.thing makes the ide think that it is not javascript or something

it gets treated at a function

and not an operator?

[hollow basalt]

[midnight wind]

@next igloo syntax highlighting?

don't look at syntax highlighting

vscode is not an ide, just remember that

[hollow basalt]

he who hath syntax

[midnight wind]

I like it because it's not a full ide

[midnight wind]

learn how to use a debugger

I can help with that

this way you can see all properties of slice

[next igloo]

do i go start debbuging?

[midnight wind]

yeah for starters you can use console.log()

[hollow basalt]

Debuggers are good but I still use plain old logs

Why are you using slice in response

I suggest you take a look at discord documentation first

[midnight wind]

and js in general, I'm still a noob in js though so I can't help much

[hollow basalt]

Don't need much, as long as you have the fundamentals of http apis

[midnight wind]

well discord.js wraps around the http api's though?

[pliant siren]

Yes.

[next igloo]

the issue was msg was an object

i fixed that now

[umbral saffron]

would it be worth it to buy a watch controller for the helmet
it would just swap between the cameras, turn on the flashlight, and i guess connect the screen

[midnight wind]

wdym by watch controller

[umbral saffron]

it would just swap between the cameras, turn on the flashlight, and i guess connect the screen

for the helmet

im working on

its a screen on ur wrist with a strap

@midnight wind

[midnight wind]

so like custom made?

I really don't know what you are talking about

[umbral saffron]

ok so take an apple watch

or any smartwatch

it has a screen and a band right?

instead of being connected to ur phone

this is connected to ur rpi

as a remote

[midnight wind]

ok yeah

I know that

but about the controller, wdym? a custom made pcb? what are you thinking about

[umbral saffron]

the watch is the controller

sorry im making this confusing

we have a helmet right

[midnight wind]

isn't that the pi?

[umbral saffron]

yes

but its a 0

and we have no way to interact with it

so would buttons or a watch be better

it would just swap between the cameras, turn on the flashlight, and i guess connect the screen

[midnight wind]

but the pi is the watch though? It's the hub where verything is connected?

there are GPIO pins for a reason

[umbral saffron]

we have the pi in the helmet

[midnight wind]

oh

[umbral saffron]

the pi connects to the GPIO board

and that to the cable and the cable to the screen

we need a way to control the pi

would a watch or buttons be better

[midnight wind]

isn't the screen touch?

if it's not that would be a good option

[umbral saffron]

the screen in front of the helmet? no
but the watch screen? yes it would be

[midnight wind]

What watch were you thinking about

[umbral saffron]

?

[midnight wind]

Like what watch did you want to buy

You would want something similar to a pi with an i2c or something similar for data transmission

And programmable

Or bluetooth

[umbral saffron]

what i would do

is use a bluetooth screen with a band around it

with one wire for power

[midnight wind]

Yeah I would do that

[umbral saffron]

can u help me find one the one i saw was too expensive

i have a budged of 150 and we've spent about 2/3 of it

[next igloo]

hello, how can i make my bot run for 24 hours straight? (the bot is text based)
currently the bot runs for 5-10 minutes after i type node app.js in vs code or 5-10 minutes after someone has given it a command

if its offline it wont respond to commands

[midnight wind]

do you close the cmd prompt?

or close node

you need something to host it

discord won't host your bot for you

@next igloo

[next igloo]

k

its just a bot for just 1 server so it should be easy to host

[midnight wind]

discord bots are easy to host

no need for port forwarding

a raspberry pi can

or you can rent a small vps or discord hosting service

a small bot doesn't need much resources

@next igloo

[hollow basalt]

[next igloo]

?

[midnight wind]

nevermind

[pliant siren]

I just wrote my discord bot to run in a container. Then you can just use an Amazon micro VM running docker that hosts the bot

[midnight wind]

yeah packing in a container is a good way to make it work everytime

[pliant siren]

In fact, here's the Dockerfile for the one I wrote.

`FROM node:12.18.3-alpine

WORKDIR /pinboy

COPY package*.json /pinboy/
RUN npm install

COPY app.js /pinboy/app.js
COPY package.json /pinboy/package.json
COPY config.js /pinboy/config.js
COPY pinnypals.js /pinboy/pinnypals.js

COPY config.json /pinboy/config.json

CMD ["node", "app.js"]`

[midnight wind]

doesn't have to be a docker container, I myself am experimenting with buildah and OCI containers

docker can run OCI containers

and so can podman

podman can also run docker containers

I also use yarn instead of npm

[pliant siren]

on alpine?

[midnight wind]

I used FROM node:12

didn't specify alphine

why?

[pliant siren]

yeah, alpine is much smaller.

[midnight wind]

ah ok

[pliant siren]

it's a pain sometimes cos you write your heavyweight container using some base image that expect say, apt-get, or yum, then you change to say alpine and f%*#%, now I gotta use a different package manager lol

[pliant siren]

No. Because then if you have even a single file that gets modified, you need to create a new image /did for that step and all those changes.

It also ensures you don't copy unnecessary files without having to add them to. Dockerignore

Not if you have a large source folder.

That would imply you have another shadow copy step.

dist should generally only contain derived assets.

So you would still end up with a new container diff at that build step. You've just instoduced a new problem and not solved the old one

That still applies.

It's the size of the diff and length of the build that is impacted

[pliant siren]

What happened? Now it looks like I was talking to myself lol

[marsh oasis]

Im running a flask server on my RPi and ive made it to run on 0.0.0.0:5000 but when i go to my laptop to connect to the site using the public ip it doesnt work...

any idea why?

and if so how can i fix this?

[marsh oasis]

wdym

[marsh oasis]

well could you tell me it?

[midnight wind]

@marsh oasis you need to port forward and enable nat reflection

In your router

[marsh oasis]

@midnight wind why would i port forward to see make it so everything on my local wifi can be visible

[midnight wind]

@marsh oasis ok, so you don't need to port forward, but you said you wanted to access it from your public ip. If you just want to access it within you lan you need to find the ip of the pi.

Making it run on 0.0.0.0 :5000 just means the pi will listen on all interfaces

[marsh oasis]

when i run ifconfig i get the list of the ip's and none of them seemed to work

[midnight wind]

Run ip addr and post here

[marsh oasis]

cant do rn but will do later and keep you updated

[midnight wind]

Alright

[umbral saffron]

That happened to me in another server

[sage vector]

I am. Doing it Dart as it has been tradition for me: https://github.com/julemand101/AdventOfCode2020

So far, it is still easy 🙂

[shy helm]

@sage vector I’m not actually caught up yet, but if you want I’m happy to share my C++ solutions 🙂

Do you try to make them as efficient as possible? Or do you care more for just solutions

[sage vector]

Efficiency is one parameter but it also needs to be readable and some kind of clean. 🙂

[slim pulsar]

Hmm never heard of this advent of code thing before

Might need to check it out

Been looking for a good reason to learn Golang and this might be it

[late plank]

how do i find the path to this title in php?

Ive already decoded the json and and named it $response_decoded

sth like this: "title" => "$response_decoded->products->data[0]->title" ?

[hollow basalt]

[late plank]

needed to remove the ""

[tall kernel]

I love html

[shy helm]

Gotcha, let me catch up and then we can talk about solution efficiencies 🙂 there are O(n) and O(n^2) amortised solutions for day one that are easy, will let you know if I see anything for the others

[bleak breach]

@shy helm It's been my tradition for the last 4 years to think about it in Feb, do 3-4 puzzles and then abandon it. 😂 🎅

[honest sleet]

I made a new video devlog for my game, about the development of new visuals, UI elements and gameplay improvements using Godot Engine! And an over-engineered ground texture feature 🤣! https://youtu.be/0xe65ckvPjs

[slim pulsar]

First time trying it out. Going to try to finish it in chunks. Do a few days at a time then wait for a few more

[gusty girder]

Does anyone know, when using C#, is there a large difference in performance between using nested if statements vs. multiple conditionals?

if(loaded_games < total_games)
{
    if (scrolled_to_end_of_list)
    {
        loadMoreGames()
    }
}

and

if(loaded_games < total_games && scrolled_to_end_of_list)
{
    loadMoreGames()
}```

[shy helm]

I double it makes significant difference @gusty girder

Both should create mostly similar instructions:

calc cond a
jump end if not a
calc cond b 
jump end if not b 
jump loadMoreGames
end

Obviously that's not real instructions, but close enough

[spring pond]

yeah i think the compiler will probably be smart enough to treat them the same

[gusty girder]

aight thanks

[pliant siren]

Modern compilers will figure that shit out.

[bright hound]

is anyone else doing adventofcode?

[spring pond]

there are some messages from people doing it in the chat history

[bright hound]

I'm trying to do it avoiding the bruteforce nest a bunch of loops solutions. so trying to use more advanced data structures.

[shy helm]

@bright hound let me know if you ever want to compare solutions, I’ve only done the first three days though

[bright hound]

so I'm doing python.. and trying to not do dumb things.. this was day 1 pt1

[shy helm]

Yeah, you can do day one part 1 in quasi linear time if you want

[bright hound]

`#!/bin/python3

with open("input") as file:
inputlist = [int(line.strip()) for line in file]

print(inputlist)

listindex = 0
while listindex < len(inputlist):
testednumber = inputlist[listindex]
if (2020-testednumber) in inputlist:
print( testednumber * (2020 - testednumber))
listindex = listindex + 1
`

[shy helm]

Part two in quasi n^2

[bright hound]

yeah got that.

[shy helm]

Yeah nice

My solutions are in C++ haha, but basically the same

Actually just to note, your day one solution is not linear

[bright hound]

I think 2 would be easier in C

[shy helm]

Your solution is n^2

List membership is a linear search

[bright hound]

if in list is O(1)

so it's O(n) worstcase.

[shy helm]

You’re thinking of sets

List member is N

There’s no order to the data, how can it be sub-linear?

[bright hound]

list datatype in pythhon does that for you 😄

[shy helm]

No, it doesn’t

https://wiki.python.org/moin/TimeComplexity

x in s O(n)

I use python professionally 😛 I’m familiar with the built in runtime complexities

[bright hound]

huh I thhoughht it was better than that boo. that make my part 2 O(n^3). 😦

[shy helm]

Yeah, have to use sets/dicts to get the O(1) amortized ‘in’ complexity

[bright hound]

and worst case remains O(n)

[shy helm]

Yes, but it’s extremely unlikely

With cuckoo hashing they can get worst case constant time lookup, not sure if python uses it though

In this example though, you won’t have duplicate keys, so you’ll always have constant time

[bright hound]

so making a copy of the list as a set and using that for the in operation.. is trivial.

[shy helm]

Yeah should be easy 😄

[bright hound]

yay for bitwise operators for day2 pt2

[bright hound]

ok it's getting a bit more involved now... `#!/bin/python3

8-9 x: xxxxxxxrk

lines=[]
count = 0
def test(line, indexno):
if line[indexno] == '#':
return 1
return 0

myfile= open("input")
for line in myfile:
lines.append(line.strip())

def testarray(across, down):
count=0
j=0
i=0
while i < len(lines):
if lines[i][j] == '#': count = count + 1
j = (j + across) % len(lines[i])
i = i + down
return count

print(testarray(1,1) * testarray(3,1) * testarray(5,1) * testarray(7,1) * testarray(1,2))
`

[umbral saffron]

ok so for the helmet thing im making would an rpi 0 be better or an arduino

[spring pond]

what are you trying to make

[umbral saffron]

its a helmet with a camera connected to a screen

[honest sleet]

With shader sorcery and clever dynamic ground tiling, I can move wormholes around, it's trippy!

[umbral saffron]

woah

[spring pond]

you will need a pi for that project because i dont know of any arduino with the processing power needed for that

[umbral saffron]

ok

so a 0 would be powerful enough?

[spring pond]

let me see

what are you trying to do with this camera feed

[umbral saffron]

send it to the screen

its an IR nightvision camera

the end product is going to have a nightvision helmet

[umbral saffron]

sorry my handwritings so bad i made it with my friend

[uncut garden]

hi, i was wondering if it's possible with traefik to define the defaultRule in the config file such that it retrieves the name a container and for each container ?

[spring pond]

depending on how high res is im not sure if a pi zero will be able to compute it quick enough

[umbral saffron]

https://www.amazon.com/Dorhea-Raspberry-Camera-Automatic-Adjustable/dp/B07DNSSDGG/ref=sr_1_9?dchild=1&keywords=IR+raspberry+pi+camera&qid=1606968300&sr=8-9

thats the camera

which goes to the pi

https://www.canakit.com/raspberry-pi-zero-wireless.html?src=raspberrypi

https://www.adafruit.com/product/1590

which goes to the GPIO pin board

which goes to the ribbon cable

https://www.adafruit.com/product/862

which goes to the screen

https://www.adafruit.com/product/1680

[spring pond]

you should be fine

[umbral saffron]

ok

[umbral saffron]

is there a cheaper driver board i could use

[spring pond]

maybe

i dont really work outside of pis and arduinos

[azure mica]

HAha Neural Networks goes Brrrrrrrrrrr...

[midnight wind]

maybe an STM32 could be fast enough to drive a screen, idk

yeah seems like it is

https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-mpu-eval-tools/stm32-mcu-mpu-eval-tools/stm32-discovery-kits/32f429idiscovery.html

[umbral saffron]

its 4$ cheaper

but it might not be fast enough

[bright hound]

@shy helm Pretty proud of my test for day4 pt1 after converting the passport to a dictionary used set(passport.keys()).issuperset(requiredfields)

[nocturne galleon]

Im doing vector<int> list;
and list.size()
and it doesnt work although it should work according to http://www.cplusplus.com/reference/vector/vector/size/
error: request for member ‘size’ in ‘list’, which is of non-class type ‘std::vector<int>()’
15 | cout << list.size();

nvm it works now

[nocturne galleon]

Why can I do list[3] after I have done list.clear() and still get the element that was there before but then when I do list.size() it says 0

list is a vector

[deep scarab]

pretty sure that's undefined behaviour

i think at() will throw an exception if you tried that

[hollow basalt]

Undefined, I think it's not guaranteed to do the memory cleaning immediately

[hollow basalt]

<@&750150305383186585> so uhh

[midnight wind]

um

[umbral saffron]

what happened

[hollow basalt]

it

[umbral saffron]

what

[warm sleet]

@umbral saffron STM32's have DMA

there are gfx libraries optimized to use DMA for SPI displays

stm32 development boards like the blue pill (STM32F103) are arduino compatible

but much faster.

32 bit chip @ 72MHz vs 8 bit chip @ 16MHz (or 20 if you swap the crystal)

[umbral saffron]

so it would work

i dont understand any of that

@warm sleet

[warm sleet]

@umbral saffron simple displays that you'd use with a microcontroller like that use SPI

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

The most commonly used DIY development platform is arduino

but arduinos are terribly slow, and not ideal to drive a display

don't get me wrong, it can do it. but updating pixels will be lot slower

[umbral saffron]

i was planning on using a pi bc i have no idea how to use an arduino and it might be faster

[warm sleet]

@umbral saffron arduinos are not that complicated

you connect them to your computer with usb

and you can use the arduino program to upload your code to the board

It does not contain an operating system

[umbral saffron]

all i need to do is connect a camera to a screen

[warm sleet]

the code it runs, is your program

[umbral saffron]

so would an arduino be better

[warm sleet]

Nah

if you want to do realtime streaming like that

you kinda want a pi yeah

[umbral saffron]

yeah thats what i thought

but im still new to all this

[warm sleet]

if you just want to drive a simple display

[midnight wind]

arduino is too slow (depending on the chipset)

[warm sleet]

then a pi is overkill

[midnight wind]

a pi is a full on computer

[warm sleet]

@midnight wind those avr chips all suck ass

but they go far smaller

attiny25

is

tiny

https://i.imgur.com/xWcko19.png

thats magnified like 20x

[midnight wind]

an arduino or any microcontroller (Ex: stm32) can't run a full on OS (or can it, idk, but not designed for that)

you program it directly

[warm sleet]

@midnight wind microlinux can run on an stm32

[midnight wind]

huh

cool

[umbral saffron]

being able too fit the pi into the vero board into the pinboard is gonna be tight

bc this is going onto a helmet

[warm sleet]

https://i.imgur.com/JKe9HNo.png

[umbral saffron]

but the veroboard is better bc im only using 1 thing that im plugging into it

[warm sleet]

the stm32 discovery is the official dev board

but there are compatible kernels for it

@midnight wind the only thing the kernel will really do, is just run your init script

kernel boot parameters contain the path to your init script

which the kernel runs after it starts

this would work with this right

[warm sleet]

@umbral saffron use breadboards

[midnight wind]

for prototyping

[umbral saffron]

yes i was going to

[warm sleet]

https://upload.wikimedia.org/wikipedia/commons/thumb/7/73/400_points_breadboard.jpg/1920px-400_points_breadboard.jpg

[umbral saffron]

but i need it to be smol

[midnight wind]

but for a final product you could use that

[umbral saffron]

and im only connecting one thing

[midnight wind]

yeah breadboards are too big

[warm sleet]

yeah but for prototyping your hardware & software

its fine

when you go to build your first actual prototype of the design

you could use perfboard

[umbral saffron]

whats wrong with the veroboard

[midnight wind]

make it on a breadboard first

[warm sleet]

its perfboard

[umbral saffron]

meaning

[midnight wind]

make on breadboard -> make sure it works -> then solder

breadboard is solderless

[warm sleet]

vero is a brand

[midnight wind]

perfboard you need to solder

[warm sleet]

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

[umbral saffron]

ah

[warm sleet]

vero is a brand

if you want to go smaller still

[midnight wind]

make your own custom pcb

[warm sleet]

you can order custom designed PCBs online these days

[midnight wind]

fusion 360 has eagle built in now

[warm sleet]

all you do is send your gerber files from your cad software

I use kiCad

[midnight wind]

that's nice too

[warm sleet]

https://kicad.org/

[midnight wind]

I used it before

[warm sleet]

takes bit of getting used to

but it does basically all you need

[midnight wind]

I'm just like the eagle <-> fusion intergration

[warm sleet]

netlists, autorouting

etc

and if you have the latest version

it has almost all commonly used electronic parts in its db

eagle is piss

because its monthly subscription now

[midnight wind]

I have it from school

[warm sleet]

yeah

[midnight wind]

¯_(ツ)_/¯

[warm sleet]

thats how they get you

Its the same for me with IDEA

[midnight wind]

yeah true

[warm sleet]

microsoft does it too

except they make the school pay for it

[midnight wind]

and adobe

[warm sleet]

yeah it creates people educated to use this one system

[midnight wind]

there aren't any like Blender type of good free CAD programs

[warm sleet]

instead of teaching them how to teach themselves more

like

all these cad programs

have same kind of views of a pcb

you have the schematic

then your board

netlists

which translate the schematic to the board

and then you can get a 3d view as well

https://kicad.org/img/frontpage/kicad_3dviewer.png

hack yeah

[midnight wind]

oh that's kicad?

[warm sleet]

https://kicad.org/img/frontpage/kicad_pcbnew.png

board layout

[midnight wind]

yeah it's all similar

[warm sleet]

@midnight wind only 3d modelling I've ever done

was with this uhm

https://www.openscad.org/

uses code to describe your models

[midnight wind]

huh

that's different

[warm sleet]

yeah its 3d cad

for 3d printers and such

never got into this

I'm more electronics and code

[midnight wind]

blender is so nice

[umbral saffron]

https://www.adafruit.com/product/1590
all i need is a way to connect this to the pi

[midnight wind]

I wish CAD got more love

[warm sleet]

blender is for virtual scene rendering

like

[midnight wind]

yeah

ik

[warm sleet]

openscad can compile to GCODE

which are commands to operate the printer

[midnight wind]

yeah, I built a cnc

[warm sleet]

nice

[midnight wind]

I've worked with some gcode

[warm sleet]

its quite bad isnt it xD

[midnight wind]

need to improve it a bit though

yeah

[warm sleet]

very nitty gritty process

[midnight wind]

the worst is the wobble

[warm sleet]

omg

https://i.imgur.com/jdC5xvq.png

are you serious

what kind of ripoff is this lmao

minimum order of 8

for 56 bucks

[warm sleet]

@midnight wind https://www.ioccc.org/

[midnight wind]

what's this

[warm sleet]

its a recurring contest

https://i.imgur.com/SpFYXw2.png

[midnight wind]

huh

[warm sleet]

its like a hackathon

[midnight wind]

it takes a good programmer to write bad code

[warm sleet]

except they compete to write the most obfuscated spaghetti code ever

so its impossible to deduce what its attempting to do

@midnight wind giving you gems like these: https://www.ioccc.org/2019/adamovsky/prog.c

[midnight wind]

oh god

[warm sleet]

@midnight wind thats an unlambda interpreter

http://www.madore.org/~david/programs/unlambda/

[umbral saffron]

half life

[warm sleet]

@umbral saffron https://en.wikipedia.org/wiki/Anonymous_function

[umbral saffron]

what

[umbral saffron]

i was saying this symbol (made by the spaces) is the symbol for half life

[warm sleet]

yeah

its lambda symbol

[umbral saffron]

oh

[warm sleet]

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

in functional mathematics it can be used to describe a function

and computing also uses it

in javascript for example

() => console.log("hello world")

[umbral saffron]

all i remember is
alpha beta gamma delta epsilon zeta eta theta iota mu nu omnicron pi tau opsilon fie chi psi and omega

[warm sleet]

this is an anonymous function

[umbral saffron]

ah that was the part i didnt understand

[warm sleet]

so you can store them in a variable

foo: () => console.log("hello world")

[umbral saffron]

oh

cool

[warm sleet]

so you can do myObject.foo()

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

[shy helm]

in Racket lambdas are actually identified with the lambda symbol

[warm sleet]

did you declare it?

[patent arrow]

i declare it with x=0

the same line

[warm sleet]

declare -i x=0

[patent arrow]

y tho? i did y=0 a few lines above and it worked

[warm sleet]

https://bash.cyberciti.biz/guide/Create_an_integer_variable

`x=0'

I think your quote is worng

` '

[patent arrow]

the quote was from the terminal

[warm sleet]

' `

well then

did you add a #!/bin/bash ?

[patent arrow]

yes

anyways i added the declare. doesnt change anything... :(

[rough zenith]

Guys i don't know what im doing wrong? can't seem to get my visual studio to upload... actual code to github

have you tried uploading

no

[rare wolf]

Do using atom, github's editor, just open the same file, assuming you have github desktop, otherwise download that as well

Tell if it works

[hollow basalt]

or use command line

Why is it that multiple professional programmers prefer buying a mac over windows laptops when many times the raw power of equivalent priced windows laptops is greater?

A general question

[vestal glen]

My guess is that they went to mac for the easily accessible posix environment, since that's only recently become a thing on windows.

(and yes, I'm saying that not everyone wants to bother with linux, as much as that pains me)

[vast echo]

linux on laptops is so finicky

and sure there are cheaply built, best specs for the money windows laptops that beat macbooks for price to performance, but even the intel macbooks were reasonably competitive with similar "premium" windows laptops like the dell xps/surface devices (which are the most common dev laptops for windows users from what I've seen)

and with the m1 macbooks, it seems like the macbook air might now be the best value in it's price category if there's nothing that blocks you from using the new architecture

[crystal tundra]

The good ui with a *nix interface, long lasting hardware

U gotta admit although macs are more expensive, they last so much longer, with equally priced windows laptops lasting around 4 years whereas a mac can last 8

And now the m1s add performance

[night pewter]

guys can you help im devopeping a game and it shows that there is an error i dont no what

[midnight wind]

well, the error would help

[night pewter]

what

[midnight wind]

what error are you getting

[night pewter]

assets/player error expected

[midnight wind]

full error

that doesn't really help

[midnight wind]

well, it's kinda obvious

read the error

[night pewter]

i did and i dont no

please tell me

[midnight wind]

cmon

what's the last 2 works say

[night pewter]

i just started devopeping 2 days ago

[midnight wind]

; expected

at player.cs at line 11

[night pewter]

ok

let me check that

[fallen cedar]

maybe worth teaching how to read this particular error message

if he's new

[midnight wind]

I'm a bad teacher but I'll try

[night pewter]

ok the errors are gone now but for some reason what i coded its just not happening in game

[fallen cedar]

[15:34:11] -> timestamp of the error message
Assets\player.cs -> error is in this file
(11,35) -> error is on line 11, column 35
error CS1002 -> it's compiler error CS1002 https://docs.microsoft.com/en-us/dotnet/csharp/misc/cs1002
; expected -> the error message

so in short: you were missing a closing semicolon

[night pewter]

ya

[midnight wind]

yep, basically same thing

[night pewter]

i no i fixed it

[midnight wind]

ah it's the error code

[night pewter]

but for some reason what i coded dident happend in the game

[midnight wind]

welcome to programming

[night pewter]

but before i coded that last line it was perfectly fine

[midnight wind]

are you using a game engine

[night pewter]

ya unity

[fallen cedar]

well, that's beyond my help 🙂

[midnight wind]

idk unity, so I can't really help you

[fallen cedar]

logic errors, especially game programming 🙂

[midnight wind]

what line did you add?

[fallen cedar]

i don't know Unity either, but you can try debugging your code

setting breakpoints

[night pewter]

@midnight wind ok thanks for the help tho

[fallen cedar]

stepping through the code

and see where reality starts shifting away from your expectations 🙂

[midnight wind]

I'm currently in the progress of doing that for a js game

working on an animation system

preloading all the images was going to be a problem, but then we found out about sprite sheets

so now I have to implement that

mozilla's dev site is great

[pliant siren]

If you want the easiest time ever handling sprites, have a look at the way it's done on the GameBoy Advanced.

All except that the ARM7tdmi didn't have FDIV, that thing was awesome and so easy to develop for.

[nocturne galleon]

my favorite thing in the entire world is following a tutorial step by step and getting errors thrown all over the place and nothing works :)

[sacred pumice]

@nocturne galleon https://www.youtube.com/watch?v=MAlSjtxy5ak 😄

[hazy salmon]

Hi guys, I'm looking for software that can do the following:

• Manage text/config files
• Editing 1 single setting in multiple config files at once, without changing the other settings
• Basically a tool to automate editing multiple config files

For exampe, I have 2 config files:

value: 20```

```server_name: test2
value: 20```
Now I want to edit value to 30 in both files in one go without having server_name changed in either.

There must be something like this right?

[sudden tiger]

this is even better 😂 https://youtu.be/_WH6cbwZ5m8

[fallen cedar]

i don't know of a "tool", but if you have config files that follow the above pattern you outlined, so property: value, then you can just write a simple one shell script to modify multiple files

in Linux (assuming you have two files (test1.cfg and test2.cfg in the current folder with contents similar to what you provided)

sed -i 's/\(value:\).\+/\1 500/g' *.cfg

will change the line value: 20 to value: 500 in both files.

In Windows using PowerShell

(Get-ChildItem *.cfg) | %{ ((Get-Content -Raw $_) -replace '(value:).+','$1 500') | Set-Content -NoNewLine $_.FullName }

of course this only works if all your files are in the current folder and they strictly follow the pattern you mentioned:
property-name, colon, space, some value, end-of-line

[sacred pumice]

lol, times like this I'm thankful I did most of my learning before the days of Youtube 😄

[pliant siren]

Grep and sed.

oh right, someone already said that 🙂

[nocturne galleon]

Hey I was wondering if there is an easy way to make estimates on how long a project can take to build, I am beginning to learn the basics of web dev and have an idea for a website I would want to build but no idea how to gauge how long it might take. Does anyone know of any ways to figure that out? I understand if that might be possible but was curious if people who know alot more than me might be able to point me in the right direction

[spring pond]

due to how many factors can go into code projects it can be very hard to estimate time frames

i originally had a 6 month time frame for my project but its gonna end up taking about 10

[pliant siren]

like build time or project management time to finish?

My boss used to take whatever estimate I gave him then triple it 😉

[midnight wind]

do you have any experience? Making a basic website can be pretty easy, but once you add a backend component, complexity quickly rises.

Also, is it just a basic information website, or something that will require a lot of custom coding

[nocturne galleon]

A fair amount of custom coding and back end, I am still pretty fresh but I have got the hang of making simple static pages. Using Vue.js & Vuetify. The main thing I would need to learn is backend/data work. The idea is basically converting a spreadsheet i have into a webapp.

[nocturne galleon]

actual build time 😛

[limpid reef]

Depends entirely on the scope of the project (aka what features the client needs vs. their wants), your own personal experience building such a project, and expectations set with the client. Oh, and whatever you do, ensure you have a rock solid contract that outlines both YOUR and the CLIENT's responsibilities.

[pliant siren]

Not really, it depends how much of it is isolated and from scratch, and how the build can take use of multiple CPUs or even agents.

[limpid reef]

Well that's part of it for sure - actual development and coding can vary so much depending on what framework you choose to work with and your experience. I'm talking about the part clients can actually see themselves, and thus the part that usually holds up website development the most (usually because clients can be... difficult? if not managed properly) - the design & actual functionality of a website. But yeah, it's hard to say without knowing what this project actually is.

[nocturne galleon]

Thanks, that is a good point. I didn't want to explain everything to someone and have them just tell me an answer hoped I could find a way to determine it for myself. Guess I gotta just get started and hopefully after putting some more hours into it I should get a better idea of how long it can take.

[limpid reef]

Definitely look into consulting with a lawyer (or at the very least, use a generic contract template) to get expectations set in writing. I am not a lawyer, this is not legal advice, but it helps to at least have something on paper should anything go wrong during the project.
https://stuffandnonsense.co.uk/projects/contract-killer/

[nocturne galleon]

one final quick question, do you have any recommendations for back ends to use? Seems like alot of people use firebase but I have concerns over scalability and not being able to transfer user credentials to a separate db in the future

[midnight wind]

I use nodejs, but that's a low level backend server

Probably not what you need

[pliant siren]

all of this depends on other technologies you choose, and requirements.
I'm deploying a lot of my own stuff to a k3s cluster of node containers.

[limpid reef]

I'm one of those .... "WordPress" heathens, mostly because my clients enjoy how easy it is to make quick adjustments on the fly when I'm either unavailable or too busy to help. That being said, I lock down the WordPress sites I manager so the clients can't just go ham installing shady plugins, editing theme files, or otherwise break their site in a catastrophic way.

[midnight wind]

yep, I've been doing a bit of labbing with kubs

[limpid reef]

For clients that don't need the niceties of an easy-to-use familiar Content Management System, I tend to stick with Laravel + some form of SQL database (depends on the server environment) if PHP is needed, OR just plain HTML5+CSS3, usually using whatever flavor of Bootstrap or Boilerplate is current.

[pliant siren]

don't suppose anyone here can tell me this: I have a set of labels I want to print 4-per-page (or as many per page as fit, but in this case it's 4) - is there a CSS directive I can use to only apply say margin-left for elements that are not on a new row when they flow over using display: inline-block ?

[marsh oasis]

ive been trying to send a post request to a site and then sending it back to me.
the site receives the request but when i log the thing, it returns as undefined....

heres the code:

        const {body} = await got.post('https://distop.xyz/api/queue', {
        json: {
            secret: "token here"
        },
        responseType: 'json'
    });

    console.log("Succesfully sent to Distop heres what you recieved: " + body.json);
    }}

im using the got package to do this

[hollow basalt]

send the whole thing

cause right now

looks like the body should be undefined

[static wadi]

yeah body is undefined outside of where ever you do the post

[pliant siren]

withing knowing more about the libraries involved, I would generally expect that data to be passed via a callback or in to a function. I don't know what you're using but generally they're written to be async and not bother to return data from a call synchronously.

[bleak breach]

@marsh oasis try running const result = await got... rather than {body} because by doing so you’re assuming two things:

1. The return of the function will be an object
2. If an object is returned it will contain the property body

You may find that there is an error and it’s in a different field other than body.

[marsh oasis]

i have fixed it

i used axios and then i had to decode the json

lel

[cinder kraken]

so, i'm ready to burn my pc. i have a relatively simple piece of code in C that almost does it, but not quite

char payload[2048];
fread(payload, 2048, 1, fp);
a.cpuid = payload[12] + (payload[13] << 8);
a.year = payload[8] + (payload[9] << 8);

now, payload[12] = 0x81 and payload[13] = 0x06, but i get as final value a.cpuid = 0x0581
same thing happens with a.year = 0x1899, where i have payload[9] = 19 and payload[8] = 99
what am i missing here? pls ping

nvm, this went as a rubber duck debugging session
set payload to unsigned char and solved it right away

[obtuse night]

not sure if anyone will be able to answer, but i am starting a new job next month and am beginning to create my own open source application (in my own time). If i work on this by myself, outside work hours, am i correct in thinking my employer has no claim to having the application to themselves? If this doesnt make sense, please let me know and ill try and explain it better

[vast echo]

ianal but it would depend on the contract you sign

[spring pond]

^

read your contract very carefully

[vast echo]

and depending on the state/country, the contract may not be enforceable if it does claim copyright for side projects

but it definitely is in some places

I also wouldn't recommend using a work laptop or anything owned by your employer to do side projects regardless of your contract

[obtuse night]

thank you both. my current employer is very open about allowing personal projects but the new company is less upfront about it

[shy helm]

Adding on, if your side projects are mostly unrelated to your direct work at your company, and you make them on your own personal time and devices, you're probably pretty safe

Read your contract carefully, google the question for your specific area

[bleak breach]

@obtuse night You need to inform your employer of the project, and document the hours you work on the personal project if you're worried about them claiming it. If the project is in any way influenced by your day-to-day job they may have a claim depending on your contract. So the contract really is the key.

[obtuse night]

it could be seen as being influenced by current projects as my role is a bespoke software developer, just working on whatever other companies need. some time it will be finance based systems, then the next may be cybersecurity based. tbh, they probably wont even bother but it's just something i dont want to be worrying about. Thanks

[pliant siren]

Is there a chance anyone here uses Argo for kubernetes deploymetns?

[bleak breach]

No, but I've been really wanting to try it

[vestal glen]

there is a chance, yes. However I'm not sure what the value of the chance is.

[pliant siren]

The genera issue is I'm trying to define a DestinationRule but argo is not picking it up from the repo. My best guess is there's an error in the yaml but it doesn't tell me of anything like that.

[umbral saffron]

can someone help me with 3d modeling

[nocturne galleon]

Not sure if this goes here but...

So I added a helicopter into my FX server for FiveM and whenever I spawn it in I can't control it, like WSAD doesn't do anything. It only does it with add-on vehicles so... Any fixes?

I've had 2 developers look through the meta files and they didn't see anything so..

[finite coyote]

I'm looking for a way to do something in Python and im not sure how to, so any help is appreciated:
Say I have a .py script, where i have a list with 3 values, e.g values = [1.01 3.14 218].
When I execute the script, the program optimizes the values of this list and changes them over time, so say for example its now values = [1.21 4.15 201] after running the .py file.

Is there a way to modify the original list after running the script, so that the next time I run it it will start from values = [1.21 4.15 201]?

I mean apart from saving it to a .txt file, I kind of want to avoid the hassle of that.

[spring pond]

https://stackoverflow.com/questions/45175647/self-modifying-python-script

[finite coyote]

thanks!

[fluid kernel]

hassle!?

self-modifying python is way more hassle and complexity.

besides, you're still reading and writing a file, it's just also the file you are running.

[finite coyote]

I guess you're right, I thought there would be an easier way to just modify the value of a variable after running the script

[fluid kernel]

import json

def load_list():
    with open('list.json', 'r') as f:
        return json.load(f)

def save_list(list_to_save):
    with open('list.json', 'w') as f:
        json.dump(list_to_save, f)

vals = load_list()

# script here that uses, and perhaps modifies the values

save_list(vals)

not run it, but something like that is fairly simple.

[finite coyote]

Yep that seems easy enough, thanks a lot for the help!

[midnight wind]

@warm sleet thinking of maybe doing a project to control the garage door with a micro-controller powered by POE, something like this seems nice: https://www.olimex.com/Products/IoT/ESP32/ESP32-POE/open-source-hardware

[warm sleet]

@midnight wind two sensors and a motor

the sensors tell the controller if door is fully opened or closed

control motor accordingly

[midnight wind]

I could just wire directly into the door controller

[warm sleet]

oh it has one?

kk

@midnight wind I've tapped telemetry into industrial equipment before

using opto isolators

@midnight wind how does the door controller get its signal?

remote?

[midnight wind]

I would need to look into it more closely, but there are two parts. The outdoor side is wireless, while inside there is just basically a button that you can use to open/close the door

I was thinking I could just tap into the button

[pliant siren]

It amazes me that I can not find a simple arduino-type unit that simply takes a closed circuit, and then sends a REST call based on that pin short via a configured wifi connection.

hang on, that's the other problem i have. For the garage door I need to listen for a rest call and send data to the output pins.

[midnight wind]

yeah, that's basically what I want to do

[restive jungle]

Does anybody have an insight in X11? I have a problem with querying keystrokes and non us keyboards returning wrong keys. Does X11 translate keycodes into different layouts? E.g. ALTGR+Q returns 2 instead of L-CONTROL+R-ALT+Q

As a char that would be '@'. I suppose this is due to the US-keyboard layout putting '@' on SHIFT+2

[red jolt]

Anyone knows any good resource for learning concurrency in C++?

[hollow basalt]

real life

[sacred pumice]

@restive jungle I think X11 does exactly what you say actually, afaik X11 takes in key codes, and spits out characters based on the current keymap, which can be set with setxkbmap, but that's about as much as I know on the subject.

[warm sleet]

https://wiki.archlinux.org/index.php/Keyboard_input#Identifying_scancodes

keyboard mapping should be handled by udev

not all distros use udev though

keyboard events in X11 are handled by xev

I think you can use xbindkeys for that

[cloud knot]

hm.... https://pages.cloudflare.com/

Free tier, nice

[midnight wind]

I like to stay away from cf

[warm sleet]

same

there are plenty of tools to manage pages

[pliant siren]

Okay, I need to find a discord server that's crowded with seasoned devs, in this case preferably javascript/ecmascript devs.

I have some data/database design decisions to make 😄

[fallen cedar]

i tried sharing another discord server link, which is apparently not allowed (got scolded by LMG Warship 🙂 even though i skimmed the rules before i did so)

anyways, try asking here, maybe someone can help

so i think my discord link was removed because of rule #3

3. No spam
   This includes server invites, mass mentions, caps, screamers, and link spam.

While I agree with the intent, I wouldn't qualify this particular case as "spam"

[pliant siren]

ah yes, I didn't even think about that when I mentioned it.

[ivory bear]

can I know the reasoning behind it?
or was it purely because it just doesn't suit you?

because sometimes other people might not know if some service is actually not good to use and that there's actual better options etc, I'm sure others want to know that better options as well if cf is not good

[sacred pumice]

I imagine linking other discords is automatically removed, this server probably gets a lot of spam

as for finding seasoned devs, I still think IRC/Freenode is better for that, I've always had a trouble finding really developer centric and busy channels on Discord.

[midnight wind]

it's a huge service, if cf goes down then your site goes down as well. And cf goes down not that unoften

I just recently moved my dns nameservers from cf to he.net

[shy helm]

The forum uses CF, and I can’t remember the last time we were down because of them

[midnight wind]

Hmm, I have had multuple instances of it being down for a min or so

at least dns

[shy helm]

Ah, well, I definitely wouldn’t say they have bad up time

[midnight wind]

Yeah, it's not bad

[nocturne galleon]

Cloudfare is okay, but they like to force their content hosting on you instead of running straight DNS. Hurricane Electric gives you regular DNS... personally Id go with HE any day over cloudfare. They've been called the "used car lot" of providers before.

the CF dns is more like a CDN.

Looks like this might be in the wrong channel though. Probably better in maybe a networking channel or something?

[shy helm]

Eh, it’s fine in dev

#networking does exist though

[shy helm]

You can still just easily use them as a DNS if that’s all you want, it’s just one click

[nocturne galleon]

I agree. I have nothing against them, I've used 1.1.1.1 at home for a long time.

[midnight wind]

I use 1.1.1.1, 8.8.8.8, and 9.9.9.9 at home

router then caches

[nocturne galleon]

Hurricane electric just offers more control for those who are comfortable with it. They would be my choice first for that reason, but the family filters on CloudFare come in handy.

Funny I just set a router yesterday for the same combo

Adding HE actually as a 4th.

[midnight wind]

what's he's public dns server?

nevermind, got it

[nocturne galleon]

Well, kind of actuallyy. I used HE and CF for the IPv6. I'll tell you hang on. Its not as memorable off the top of my head

Looks like you can google faster than me. Lol.

Thats the way to go though, diversifying the DNS protects you from a lot of the tomfoolery.

I'm learning c++ at school and when I finish it, I want to make my first Windows program.. I have this idea, all of the games from all platforms (Steam, Epic, GOG, Origin, etc.) are all in one library, categorized by Platform, Personal Folders, Genre, etc

Is this a good idea?

I'm open to criticism

[midnight wind]

too complex, start with something simpler imo

[nocturne galleon]

It would be awesome... but the people that own the copyrights woudn't let it happen.

What do you mean wouldn't let it happen?

[midnight wind]

well, locally run it should be fine

[crystal tundra]

way too complex, kinda grey legality

[nocturne galleon]

no no, just a launcher

nothing else

[midnight wind]

yeah, just a launcher, you still would need Steam, Epic, etc installed

[crystal tundra]

still pretty complex, mess around with some command line programs a bit

[nocturne galleon]

It shows what you have installed, updates, play time and it would be synced via APIs

[crystal tundra]

u need a pretty good understanding of the language before u can make actual good apps

[nocturne galleon]

yes you would need everything else but you can check what you have all in this program

I know I just in the future when i perfect my craft

I want to know if this is a good idea

[crystal tundra]

what do you mean by good idea

[nocturne galleon]

Kodi just released a plugin actually similar to what you are discussing.

[crystal tundra]

there are lots of good ideas

[nocturne galleon]

Its not real though... just a concept piece let me see if I can find a link

[nocturne galleon]

if people would use it

it would be free obvs

with donations as optional to continue development

[crystal tundra]

if ur looking for something to go widespread its gotta be really good and you would have to be able to spread the word somehow

[nocturne galleon]

yup i figured

but you, the consumer, do you see a use in it?

[crystal tundra]

like it sounds like a unique idea, but personally im fine using my steam library separately to my epic games library

[nocturne galleon]

as a gamer

[crystal tundra]

other people might think differently, but i think you should maybe ask in a gaming channel

rather than in a channel of devs

[nocturne galleon]

Discord is a good way to do that... lol. For that reason, I'll attached just this gif. Its probably got some ick attached to it so wouldn't go to Github and procure the binary if you like your computer. Not trying to start a bot-pandemic. Since it isn't real it does work in the Dev chat (as aproof of concept)

https://imgur.com/rHgDFw1

It would be an awesome idea though if it was a real thing.

[spring pond]

this idea already kind of exists on desktop, its called playnite https://playnite.link/

[hollow basalt]

yea

[spring pond]

https://github.com/JosefNemec/Playnite/ its open source if you want to look at the code, its in C#

[nocturne galleon]

Nice!

Looking at it now

I'm running Arch... the code is working? I'll give it a test drive if its ready...

Ooops give me a few I'm coming off of a fresh reinstall and I don't have a complier installed. I'm impressed from what I see thus far. I'll circle back.

[warm sleet]

@nocturne galleon lutris is another big one

https://lutris.net/

[nocturne galleon]

I have Lutris already actually... not a big gamer so I havent played with it much

[warm sleet]

Lutris also has scripts for configuring proton with some windows only titles

for using DXVK

[nocturne galleon]

Not famililar at all with DXVK. I'm assuming its a compatablity layer? Wine for DirectX or something like it?

Forgive the NOOB question...

[warm sleet]

Its a DirectX implementation with Vulcan, another graphics API

Allows windows only games (DirectX is windows only) to run on linux systems with WINE

Valve actually forked WINE and added DXVK to it, calling it "Proton"

Proton is bundled with Steam for linux

[nocturne galleon]

That was my next question though was what that meant for playing games on Linux. I always hear about Linux gaming being terrible but from what I've seen Windows games were playable through WINE. Good to know thats true.

I hardly play tetris on my phone, let alone PC games... lol. Just learning.

[warm sleet]

the performance issue is mostly with newer games

[nocturne galleon]

Drivers?

[warm sleet]

since a lot of optimizations for games are done in the graphics drivers

and drivers, are a major issue with nvidia specifically

amd is not as bad

Games on DXVK don't get to enjoy the optimizations done on windows sytems

[nocturne galleon]

I know how the big companies are... for sure. NVidia requires a kernel mod, right? That puts it out of the way of most casual users for sure.

[warm sleet]

Because they run directX as Vulcan

@nocturne galleon yeah so in linux, its kinda 'taboo' and bad practice to run user-space drivers in the kernel

drivers shouldn't live outside of the kernel source tree

but with nvidia they do

So they use DKMS to load a kernel module afterwards

It works, and its fine

but the issue is that the drivers are not optimized to the degree the rest of the kernel is

because nvidia does not even have technical documentation on how their hardware works

They sell us chips, as a black box, with a binary blob to use it

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

[nocturne galleon]

Got it... makes sense. I got into linux after doing windows IT for a long time... so still just learning. Most of what I do know comes from the distro of Linux I finally settled on... its called Sailent OS... its just Arch though. Thats dissapointing that NVidia can't pull their head out of their butt like that

[warm sleet]

nvidia is anti technology

[nocturne galleon]

I know Broadcom did it with WLAN chips too

[warm sleet]

they lock down features on their consumer cards

so they can sell more quadros

[nocturne galleon]

Anti-competition is more like it... wouldn't want the other guys to see their code. or at least thats part of it I'm sure.

Yep.

[warm sleet]

anti technology

not anti competition

look

their hardware is fine

but we can't use it if we don't have technical documentation on it

without those documents, community cannot build drivers

they have open source drivers for nvidia: nouveau

but they suck dick. because they have been built without insider knowledge

[nocturne galleon]

I have certainly seen plenty of that in other fields so I totally get it. I guess thats why I say anti-competition... but thats just a poor choice of words. They just aren't willing to invest as they should becuase of the market share. I understand their take, but Linux is EVERYWHERE anymore, and really, it has been.

They're only hurting their own pocketbook at the end of the day... the embedded market is already HUGE asis.

[warm sleet]

its the exception rather than the rule

nvidia is one of the very few companies that behaves like this

https://tenor.com/view/linus-linus-torvalds-nvidia-fuck-you-gif-18053606

Linus Torvalds did this ^

[nocturne galleon]

I saw that tjust the other day... lol

just**

[warm sleet]

in a statement on nvidia

They haven't changed since

this video is about 10 years old

thankfully, AMD is now back in the competition

[nocturne galleon]

No shit... wow. So thats why AMD is so well regarded in the linux circles.

[warm sleet]

and the AMDGPU drivers are upstreamed in the kernel now

Vega64 under linux was one of the first cards

those worked like a charm

[spring pond]

i really want to transition to linux 100% sometime but the lack of good game/nvidia support is whats holding me back at this point

[nocturne galleon]

Haha I can't type fast enough. That makes sense. They weren't very good cards under Windows though, right?

[warm sleet]

and why would nvidia go opensource lmao

they can cash in that microsoft money as bribes

[nocturne galleon]

I vaguely rememeber that.

[warm sleet]

lock down nvidia to windows only, games will have to pay microsoft for windows

Its same the same way microsoft made sure users are stuck to office 365

you give the apple people "Office for mac"

and linux people can go suck a big one

[spring pond]

i have heard some rumors (key word there) that ms may eventually transition from NT to the linux kernel and bring driver support with it, but even if they are eventually gonna do that itll take forever

[warm sleet]

@spring pond you don't have to "bring driver support"

since linux is 80% drivers

Windows is legacy technology

[nocturne galleon]

I'm on Arch with Plasma right now... you would think it IS windows honestly. Drivers is the only thing missing

[warm sleet]

What drivers are you missing lmao

excluding nvidia

everything is in the kernel

[spring pond]

for me intel wifi doesnt work on linux at all

completely broken

[warm sleet]

good 'ol propietary drivers

yeah

some wifi chipsets on laptops in the past were full of bugs

but its been years since that was an issue

[nocturne galleon]

Ture

True

[warm sleet]

@spring pond quite a lot of laptops do support the replacing of wireless chips

they are m.2 keyed

getting a replacement module costs like 20 bucks

[nocturne galleon]

Mines working perfect. They have improved a lot.

Check out SalientOS... its bootable off a flash drive. Tjats tje screenshot I just sent.

[spring pond]

i have a desktop mb with it built in so sadly thats not an option

[warm sleet]

https://5.imimg.com/data5/TN/IS/EF/SELLER-1888409/lenovo-thinkpad-laptop-wireless-wlan-wifi-card-ac3160-04x6076-500x500.jpg

[nocturne galleon]

I need to buy a better keyboard... lol.

[warm sleet]

They look like this ^

[spring pond]

but at this point i use my slower ethernet when i do use linux so it doesnt matter to much

[warm sleet]

You just unplug the antenna wires

https://i.imgur.com/qHWF67Q.png

and plug them into this ^

[nocturne galleon]

There are PCIE cards or USB dongles as well

[spring pond]

well my current use case for my linux install is going to be going away in a week or two so im not too worried

if i was using it longer-term i would invest in a pcie card

[warm sleet]

if it was long-term

I'd ditch wireless entirely

and use a cable like everyone else

[spring pond]

due to my living situation thats not an option

[warm sleet]

¯_(ツ)_/¯

[spring pond]

i would 100% do that if i could but im not allowed

[nocturne galleon]

Yeah probably best you don't go plugging anything in. I understand that.

Wireless is much, much improved over the way it used to be. I only plug in anymore when its safe, and I'm protected with a shield.

A Firewall I mean.

Thinking of nVidia I guess... lol.

Its really just a matter of preference for sure.

I used Windows for a long time. I'm still running my crazy mix of big tech. Google, Apple, Microsoft, all working on Linux now. Just attempting to learn as much as I can. Its amazing how well things can work together with a little bit of elbow grease.

Not for the faint of heart though, for sure. Thats where the ecosystems Like Apple 1 or Google 1 work out well.

Heck you can make Juniper interface with Cisco just fine if you take the time, but time is precious to most people, so having someone else simplify it works for most. I guess I like doing things the hard way... lol.

Its important for Silicon Valley to understand how scary and dangerous it could get if that balance doesn't exist. Its almost like they forgot what Sci-Fi has already shown us.

[warm sleet]

mikrotik all the way

[nocturne galleon]

I want to maintain a bit of control for that reason mostly. The inmates running the asylum isn't too far off for us.

I feel like Mikrotik is just silly difficult though. It can still be a convenient product. PFSense is a good example there.

[warm sleet]

mikrotik is superior to pfsense, in terms of features and the hardware

[nocturne galleon]

I love Mikrotik stuff... but the learning curve is crazy sharp.

[warm sleet]

yeah its a bit steep at first

[nocturne galleon]

Its running LINUX

[warm sleet]

yeah but heavily modified

they use their own drivers for lots of things

[nocturne galleon]

As is PFSense... modified BSD.

[warm sleet]

pfsense has the issue that it doesnt integrate with hardware to the same degree

a mikrotik router that uses 25 watts can push 10gbit/s

pfsense, by the time you've spent 3x as much money, for 1/4th of the bandwidth

[nocturne galleon]

What is OSX? BSD. What is Linux? BSD. I don't disagree that in a commercial setting it makes since to go with the packaged product... but for me its about doing it for the right reasons. Time IS money. You don't see much Mikrotik in commercial installs for a reason... it would take 900 hours for the average guy to learn it at scale. Dell will sell you something preconfigured. And thats OK. Thats where we should focus on differentiating ourselves.

[warm sleet]

what

I don't hire companies to do my network installs

I install networks myself

and I find mikrotik much easier to use, than other enterprise platforms such as cisco

also, linux is not BSD.

where are you pulling that from??

[nocturne galleon]

I'm not trying to create an issue, certainly not. Its just about the right product for the job.

[warm sleet]

OSX has their own kernel

XNU

[nocturne galleon]

Its a derivitive.... thats all I meant.

[warm sleet]

@nocturne galleon unless you do carrier level exchanges, mikrotik is perfectly fine

they serve the lower to middle segment

up to ~80gbit/s

[nocturne galleon]

Its origins is in the same place. I never meant its exactly the same.

[warm sleet]

but they have all the features you'd want in an enterprise setting

[nocturne galleon]

I agree... and I've used it there.

I guess what I'm trying to say is the competetion is GOOD... we don't want to be TOO compatable becuase then we turn into a Staney Kubrick flick. Thats all.

[warm sleet]

mikrotik mainly competes with other lower end brands

but they completely stomp on tplink, asus, dlink, netgear, and the likes

[nocturne galleon]

Absolutely. I have had some issues with build quality with them.... but in general they have been very good for me. Have do done any kind of training with Mikrotik?

I'm thinking about getting some kind of cert and that was one idea on my radar was the Mikrotik stuff.

Just becuase its not that common and I'd like to diversify myself that way.

[warm sleet]

You can get training for mikrotik, but you can self teach

lots of infos on the wiki

I gotta go rn

ill ttyl

[nocturne galleon]

Oh absolutly yes... I just meant for the cert.

Ok Take care!

Sometimes... the truth hurts. But you can't argue with it. Its for our children's welfare... not just our pocketbooks today.

My point of view at least.

🙂

[fallen cedar]

on the unified launcher idea someone mentioned earlier

• yes, it's a good idea
• it's complex if you're just learning c++
• there are already solutions for this (this shouldn't discourage you though)

[rotund plover]

Someone into assembly?

[midnight wind]

@rotund plover I know someone who is but not in this server

They made their own os from scratch in assembly

I'll send an invite to a server they are in ( it's a flight sim server) if you are interested

[rotund plover]

It's ok I got it right 😬
Thanks

[midnight wind]

to make games or the underlying tech behind it

to make games the scripting engine uses lua

[lunar quail]

how is lua, honestly? I've not done anything with it.

I'd really like to pick up rust. Some of the small stuff I've written in C I'd like to rewrite in rust.

[midnight wind]

I never did anything big with it, just some flightsim scripting

[hollow basalt]

Why are you wondering why he's wondering if anyone knows assembly

[rotund plover]

Why not wondering? A lot of people not using assembly daily and don't know how to program in it.

[hollow basalt]

nothing is truly weird

it's just viewed from a different perspective

[summer cave]

Wtf

[nocturne galleon]

wrong

wrong again

you do mean like lda, sta, jne type assembly?

[nocturne galleon]

don't use go, didn't know it was so integrated

[regal geyser]

Anyone know if the LMG Warship bot was developed in house at LMG?

[midnight wind]

probobly

not THAT hard to make a bot

[regal geyser]

Oh yeah I know, I've made several

Ah got it. I wasn't sure how many people at LMG were Devs

[shy helm]

Yeah warship is built by the discord admin, floatplane is a separate company from LMG btw

[fervent orbit]

[deft sigil]

anyone an idea on howto fix this , in a way that navigation up the tree works again? , python interpreter has no problem running it but pycharm is complaining , its about the no ref in init popup. (ps all the options it gives to fix it just remove the warning but dont solve the navigation/(and less important codecompletition) problem)

i have already tried reinstalling pycharm, invalidate caches a couple times, reset to default settings aslwell, adding the funcition to init just links to that function but not to the actual mido function. and yes its python2.7, but its wat Live10's framework still uses. so stuck with it

[umbral saffron]

Ok so if I have a 40 pin screen can I plug it into an extension cable and connect that to an rpi 0 wh

And if so

How

[shadow furnace]

coding in a nutshell.

[sacred pumice]

I keep checking back in here to see if there's something I can help with, work as a Python/Django dev, I read that and I'm like "Yay, my time to shine" and then he's like "I fixed it" 😦

@deft sigil in weird circumstances where the linter complains but has no reason to, you can add #noqa to the end of the line to suppress the warning.

[warm sleet]

@deft sigil make sure pycharm is configured to use the same interpreter as your system

pycharm has its own interpreter, you can also tell it to use the one on your system, as well as venv
