I mean, can't you just get openjdk-9-jre with apt?
umbral saffron
so i made a thing with TensorFlow Lite on my pi
how would I do a command like
if Human = in_frame:
#unlocks the rest of my code
else:
print("Please put face in frame")```
spring pond
im no ml expert but i think you need to train a model
you can find them around the internet
just search something like "tensorflow face detection model"
urban flint
Also one equal is assignment two is comparison in python
umbral saffron
just search something like "tensorflow face detection model"
i have that i just need to make the unlocking system
spring pond
you need to ask someone with more experience
i have 0 with ml
but if you need to do your own face then thats a lot more complicated
you need a completely new model
with your face in it
midnight wind
@umbral saffron what you would want to do is use callbacks
So when tensor flow detects face it will trigger a callback you specified
umbral saffron
python
midnight wind
python
Idk, but do research on callbacks
Basically you give a function to a function and that function will call that function depending on when you want it to
spring pond
what library are you using for video input
spring pond
i usually use something like opencv for camera stuff
midnight wind
@umbral saffron have you looked at documentation and examples
that's the best way
it's usually more complicated then you think
lament cave
thonny is the worst IDE
if you have a separate computer you can run pycharm on it, I don't really recommend using pycharm directly on the rpi unless you have the newer model with at least 2gb ram (since it uses quite a lot of ram in my experience)
warm sleet
@umbral saffron you can just mount the program directory on your rpi to your local development environment, with sshfs
sshfs user@host:/path/to/dir /mnt/rpi
this would mount your raspberry pi to /mnt/rpi
if you then also spawn a regular shell, you can remotely debug too
umbral saffron
Ah ty
warm sleet
@umbral saffron just connect as root and mount sshfs root@ip:/ /mnt/rpi
make sure the directory /mnt/rpi exists on your system, and is empty.
you can unmount with
umount /mnt/rpi
now you can view the entire device
all its files
and everything
so settings would be in
/mnt/rpi/etc
@umbral saffron this is one of the big things that i like, and windows has a lack of. Sure, you can do network sharing
but its all so overcomplicated and nonreliable to immediately work
@umbral saffron https://github.com/billziss-gh/sshfs-win
There's also this
allows you to map a windows network drive, to sshfs
instead of \\192.168.88.10\bla
pliant siren
can I use an rsa/dsa key? :?
peak acorn
idk
pliant siren
yeah, it's a bit hidden, you have to use
\sshfs.kr[LOCUSER=]REMUSER@HOST[!PORT][\PATH]
and that forces you to use %LOCALUSER%/.ssh/id_rsa
midnight wind

LaTeX is baad
errant tapir
Its stupid weird
warm sleet
@errant tapir like random values?
floating pins you should tie to ground through a resistor
@rancid nimbus that's the same in essence, scp is just a subset of ssh
@errant tapir for buttons and such on an arduino, you'll always want to tie those pins to ground
only when you press the button, the resistance changes, and can you register a button press
If you don't reference those pins to ground, you'll have floating values randomly going up and down
midnight wind
All my arduino unos just pick up trash on the pins
how are wiring it?
you know, arduino is just an easy to use microcontroller, you kind need to wire it correctly for it to work
vital blaze
LaTeX is baad
LaTaX is great!
errant tapir
idk what my problem is
i wire the ground to the other side of the pin and it doesnt work but same side it does
thats what i was going on
but
doesnt work
resistor has to be on other side with the pin
autumn swan
resistor has to be on other side with the pin
Yes. When it's like you're picture, the pin is connected to nothing (is "floating") still. You need the pin to be "pulled" gently to ground at all times, and then when the button is pushed, 5V goes through but has no resistance so the pin sees basically the full 5V.
The onboard/software pull-up is good too, but if you're just learning this, then there's value in doing it with the hardware instead of just the software so you can see what's going on and make sense of it.

ok so i bought some raspberry pi picos to use as HID devices. i need to make a 2-key and a 4-key keypad.
Since i got 2 125mhz cores, will it be faster (or even a good choice) to handle USB in core 0 and input in core 1?
autumn swan
I think that's a good case to just chose the simplest option, since your max poll rate will likely be overkill even on just one core
woeful rapids
hmm yeah 100hz is way less than 125mhz and theres no calculations on the device so it'll be fine
hmm

Hi, I'm having trouble cutting down on latency with ffmpeg, this is basically something that streams the screen into the stdout which gets piped into a web server to be streamed to the client, I've been playing with some options to try to cut down on lag, and have managed to get it to about 5 seconds of delay, can someone help me cut it to at least one second of lag if possible because I will be adding a feature to give mouse control. Part of the slowness might be because I'm running this in a linux vm since i'm going to be deploying to a linux machine. I based this off a npm package called stream-screen.
Note: although haste says so the language is javascript, I'm not planing to add types any time soon

Hey
I need to determine the biggest maths exposant using a maximum value and a "base" so by example, if someone inputs 2 for the base, and 100 for the maximum value, the closest value would be 64 and it'd be 2 exposant 6
how can I do that
warm sleet
@wind oracle exposant?
you ment exponent?
highest value in base2 you can calculate as such: 2^n - 1
for base10, it'd be: 10^n - 1
@wind oracle if you want it the other way around
you're looking for logarithms
@wind oracle https://i.imgur.com/JViVvLR.png
10-log of your highest value, divided by the n-log of your base (binary is 2, decimal 10)
ofc, fractions would be rounded up

you could use a nested loop and multiply the two indicies (plus one on each)
hollow basalt
so this is your homework
wind oracle
not really
for (int i = 1; i <= valMax; i++) {
System.out.println(valMax + "x" + i + " = " + (valMax * i));
}
}```it's a small part of it
ebon viper
Has anyone ever worked on Unity’s A* or navmesh by any chance?
peak acorn
alright so I need to print out something like this
So a N by N multiplication table?
The string formatting is for the gaps between numbers
For c in each col
for r in each row
printf("%5d", r*c)
format as you need
and for java that'd be System.out.printf("%5d", r*c);
I come across a problem
how do you do like "%5d" but with a variable instead of 5
2 string formats?
spring pond
personally i'd use interpolation but that would also probably be possibly as well
spring pond
yeah it doesnt exist in java
the highest upvoted answer is a string.format() call for interpolation lol
*on SO
peak acorn
yea so like
System.out.print(" X | ");
for(int i = 0; i < rows; i++)
{
String s = String.format("%%%dd",maxLength);
System.out.printf(s, i);
}
System.out.println();
%%%dd lmao
man writing stupid formatting things like that dudes assignment up above is such a pain
well there we go anyways

peak acorn
:)
wind oracle
I don't understand
peak acorn
what in particular
wind oracle
well most of it
like I usually need stuff to be explained part by part idk
what im guessing is ill need 2 for loops
peak acorn
Yes you certainly need 2 loops
shy helm
One hint
Start by writing the output row by row
Get the basic part of the table built
Then, figure out how to write the first row of calculated numbers
wind oracle
wdym writing the output row by row
shy helm
-
- | - - etc
shy helm
It’s from the input right 😉
wind oracle
yessssss
shy helm
If there’s 5 numbers, you need the 5 rows for the numbers + the rows you statically (always) have (like the X | row and the - - - row)
wind oracle
that's like the only thing im missing to turn my homework in
shy helm
Look into how printf strings work
wind oracle
yes
peak acorn
hint: dont println
peak acorn
Found a program for that pdf editing. Xournalpp
works good
I would always use %d for numbers
im not sure what the difference is tho
peak acorn
screenshot?
wind oracle
peak acorn
%n makes it so on you either get /n or /r/n
peak acorn
Well, since on the example code you print you all the numbers once
that should be its own loop
wind oracle
how the fuck
peak acorn
I always seem to have this problem
idk how you can explain how to code something without just saying how you code it
autumn swan
It usually works much better in person unfortunately
peak acorn
yeah
well ill try
if you can accurately generate the top line of the sample then ur in a good spot
wind oracle
like the first loop x5 ?
peak acorn
that first gap might be too big but im not entirely sure
doesnt matter, thats an each change
I would just continue
wind oracle
I am lost
peak acorn
Do you know how string format for numbers works?
i think what you need to do
is use "%4d" or something, what that does is adds blank spaces before your number
so that the total length of the value is 4 characters
peak acorn
the *?
peak acorn
yeah so instead of printing i
you have to print i * n whatever n might be i dunno yet
wind oracle
n would be my dividend ?
peak acorn
what do u mean by dividend
peak acorn
oh
u might have the wrong word
idk if language barrier or anything but
divisor and divident are for division
wind oracle
oh
peak acorn
Divisor / Dividend
wind oracle
im a french canadian
peak acorn
For multiplication it would be, idk multiplicand?
wind oracle
oh yeah

but now you know what i meant
peak acorn
so for row 1, you multiply by 1, row 2 u do i*2, etc
simple
Put another loop around your loop for printing the multiplication
peak acorn
maybe at first but its not so bad
You can already print 1, 2, 3, 4, 5
so now we have to print it multiple times
peak acorn
You can re-use your code for your first line and modify it
so copy it and make a new one of it
and put a second loop around your printing code
peak acorn
oh
wind oracle
wtf
peak acorn
change the outer variable to J
wind oracle
peak acorn
little j
or thats fine
variable names are irrelavent
yup
so
you need a new line
after the end of the loops
simply system.out.println()
wind oracle
I add that to my loop that's in my loop ?
peak acorn
!
wind oracle
but the multiplications tho
wind oracle
yeah thats what I was looking at
peak acorn
what do u think u gotta do
wind oracle
huhhhhh the ----- must not be complicated I think
peak acorn
that sounds simple to me
wind oracle
alright buttt it has to have it's own loop nah ?
wind oracle
huuuuuuuuhhhhh
peak acorn
within your loop try to get anything that resembles 1 | 1 2 3 4 going
peak acorn
whats the issue
peak acorn
yeah not that
what you want is for each row, to only print " 1 | " once
so it doesnt need to be in the inner loop
since the outer loop is for each row, and putting it in another loop would be too much
peak acorn
sure
wind oracle
look at my first row tho wtf
peak acorn
put it after your single loop up top
usually thats how u wanna structure it
you print out your line, and then move the cursor to the next line
so you print out X | 123125151 , and then put a newline
wind oracle
I don't understand the print newline
peak acorn
by newline i just mean
system.out.println()
there is a character ("%n", "\r" or "\n" depending) that moves the printing to the next line
so if you print something, then print a newline character, then more stuff, it will be on 2 lines
System.out.println() just prints a newline character
autumn swan
Hang on, didn't the assignment or whatever say you need to use String.format?
peak acorn
oh sheesh
wind oracle
autumn swan
I mean that's not a painful conversion but just asking
wind oracle
well he asked us to align our stuff correctly
peak acorn
printf probably literally calls string.format anyways
peak acorn
because you havent told the formatter to add padding
peak acorn
padding is how you can add spaces to make every print the same size
so instead of printing
1 1
100 100
it would print
1 1
100 100
discord isnt monospace so idk if that looks right on ur end
wind oracle
huhh yeah it does
how do I do that
im still wondering about the ---+-------------------
and the -----------------------
hollow basalt
I have this code to help you, though it does have a slight disadvatange
autumn swan
you can do monospace.
autumn swan
Do
Multiline
@wind oracle do you want this to solve yourself or do you want to ssee my code
you just need to tweak mine to cater to your needs
wind oracle
well im close to done
peak acorn
I mean i have all the src code to generate it of X by Y size i was just widthholding it
wind oracle
I just need to figure out my padding now
peak acorn
in favor of education
hollow basalt
in favor of *education*
me too
I don't want to exposse
though I do think that my code won't help him that much
wind oracle
big help
hollow basalt
here ya go
I ssee you added the censor
autumn swan
but atleast it works
Can't verify that for sure without using at least 4 as the input
peak acorn
oh that was the wrong file anywyas
peak acorn
yes yours is ugly
ok, padding
its basically printf("%4d", <number>);
but test for the numbers
thats just how you do it, idk how you could explain it to someone else
like a bash script?
fuck that
eeewww
hollow basalt
@peak acorn
public class Main
{
public static void main(String[] args) {
int row = 4;
if( row == 1){
System.out.println("x | 1");
System.out.println("1 | 1");

System.out.println("x | 1 2");
System.out.println("1 | 1 2");
System.out.println("2 | 2 4");

System.out.println("x | 1 2 3");
System.out.println("1 | 1 2 3");
System.out.println("2 | 2 4 6");
System.out.println("3 | 3 6 9");

thanks

my code has some slight disadvantage when the input isn't 1-4

first 10 lines fast as fuck
peak acorn
So now all you need is the ---+---
hollow basalt
@peak acorn am I insane when I created a program that generates a source code like that
peak acorn
why does your code have curly on a newline once and inline the other time
hollow basalt
just to troll fizzbuzz
wind oracle
yes
hollow basalt
yes isn't a valid answer for why
peak acorn
So you could just print a ton of "-" in a loop
wind oracle
hmmmm

no thats cool
wind oracle
how

how not
peak acorn
How to what part
wind oracle
the ---+----------
peak acorn
Have you seen the enterprise fizzbuzz?
peak acorn
the ---+----------
First try creating a for loop just to do "------" to the right length
hollow basalt
https://github.com/EnterpriseQualityCoding/FizzBuzzEnterpriseEdition
doesn't look like using apache libraries
peak acorn
import com.seriouscompany.business.java.fizzbuzz.packagenamingpackage.impl.Constants;
lmfao
hollow basalt
hollow basalt
what if the caller only wants one instance
hollow basalt
im no pro coder man
singleton = single insstance of class
my ss iss broken
damn it
peak acorn
is that not just new Foo();
hollow basalt
is that not just new Foo();
but you need to make ssure there is no other Foo running at the same time
wind oracle
MMMMMHMMMMM ??????
hollow basalt
i tell u im no pro
well, your code iss much better than mine
peak acorn
I was thinking of just like i would make a static bool lol
peak acorn
MMMMMHMMMMM ??????
So now you need the + and maybe formatting on the top line
I'll leak my src after hes done
maybe i should fix up some of the bugs it has
or the uglyness
wind oracle
the + hmmm
peak acorn
My method for that is kinda bad
but
You could say if you're on the right spot to add the +, add the plus, otherwise, add -
its bad cos it adds a conditional that is pretty much not necessary but
peak acorn
you can just play with the numbers until it works now
peak acorn
u got it yet?
peak acorn
Your system rn looks fine so you're close
also one thing, up top where you print(" X ") you should remove the first space, so that it lines up with the other numbers
peak acorn
So you could make it loop 1 less time, and manually insert a +
wind oracle
HMMM how
peak acorn
oh fuck i forgot the bottom orw
wind oracle
LOL mine is better than you now
peak acorn
class Main

public static void main(String[] args)

the way that the numbers shade the screen kinda look like log functions
ew what the fuck
screencap the result?
nvm i forgot i have linux
cool lol
wind oracle
why does my code look simpler tho
peak acorn
becos urs is simpler
wind oracle
int valMax = 9;
System.out.printf("%s", "X |");
for (int i = 1; i <= valMax; i++) {
System.out.printf("%4d", i);
}
System.out.printf("%n");
System.out.printf("%s", "--+-");
for (int j = 1; j <= valMax; j++) {
System.out.printf("%s", "----");
}
System.out.printf("%n");
for (int i = 1; i <= valMax; i++) {
System.out.printf("%1d %s", i, "|");
for (int n = 1; n <= valMax; n++) {
System.out.printf("%4d", i * n);
}
System.out.println();
}
for (int j = 0; j <= valMax; j++) {
System.out.printf("%s", "----");
}
}```Do u see this uglyness
wind oracle
lol
peak acorn
int maxLengthForColHeader = new Integer(rows).toString().length();
String beginningMessage = String.format(" %%%ds | ", maxLengthForColHeader);
System.out.printf(beginningMessage, row);
thank you tho
peak acorn
yup :)
wind oracle
you were of a great help
peak acorn
Now i got a challenge for u ppl
Are there any elements in the periodic table, where their symbols encoded in any base (using the normal 0-9;A-Z system) are equal value to its atomic number
so dos mine
oh formatted urs looks much nicer
still guy but
i have no clue what i just typed
wind oracle
why the fuck won't my shit quit
peak acorn
it has shit tier highligting in dcord
i mean tbf its about the same highlighting as vscode gives me
wind oracle
ouf my shit is too big
peak acorn
and the answer to thatelement thing is no
however if u start the encoding for bases as A=0 and Z=numberOfLettersInAlphaBetCantRemember
then theres like 4
peak acorn
:)
peak acorn
thats some big code
his homework
its definitely extra
the multiplication was only maybe 30 lines or something
exit
bash yucky
the fact u have a bash shell discord
OH
im
deaf
blind
idk
dyslexic

warm sleet
@peak acorn this is pure magic: https://i.imgur.com/jcJsBrj.png
you can just calculate how many digit spaces you need for a base-10 number :3
to string and then length compare seems so.. easy and dirty lol
warm sleet
@rancid nimbus yeah but this is java specifically
and int to string and then range count is rather expensive
10log(value) + 1
should give you max column size
2log() for binary and 16log for hexadecimal
logarithms are just lookup tables, you're not creating a string instance
so its generally easier on the system
1000 = 10^3
- 1 = 4
2log of value = 10log(value) / 10log(2)
or other way around, I forget lol
10 log is the default in this case
though I think Math.* in java has log and log10
or 2 log, I forget lmao
even java had changes with this, java8 does not declare a log10()
@rancid nimbus the reason its efficient to use logarithms is because in java, these are native functions
/**
* Returns the natural logarithm (base <i>e</i>) of a {@code double}
* value. Special cases:
* <ul><li>If the argument is NaN or less than zero, then the result
* is NaN.
* <li>If the argument is positive infinity, then the result is
* positive infinity.
* <li>If the argument is positive zero or negative zero, then the
* result is negative infinity.</ul>
*
* @param a a value
* @return the value ln {@code a}, the natural logarithm of
* {@code a}.
*/
public static native double log(double a);
and the native implementation, within the runtime is probably a lookup table
as they do with pocket calculators and such
before calculators, there were literal log tables
would be a decently sized book
with a lot of pages full of numbers
strings are objects
int maxlength = (int) Math.log(rows) + 1
string is an array of char
you just count the length of the array
Look, in C this would be fine
since you can directly check memory space
null-terminated string would be harder
since you have to iterate
Intel even has library extensions for their processors
to do logarithm calculations in the hardware
