programming

[olive sable]

rust mentioned

[hard raptor]

yeah R*st

[olive sable]

i think a fresnel lense is fine

but

the minimum focus of the stock lens is 50cm

which is too long

so ill have to throw a different lens inbetween

[opaque wharf]

@solar pilot I forgot where I put the old project, but I found this which is exactly what you're after
https://satnogs.org/documentation/projects/

It only needs Pi 3B

[solar pilot]

WOW thanks dude

[opaque wharf]

You're welcome. It's fun anyway so I enjoy searching it too. Takes me back to the old stuff I do lol

[solar pilot]

Yeah man with my new job being more in the radio comms sector it's inspired me to get more into this stuff

[tacit sage]

SHE HAS MEMORY

And can actually learn now woo

im so proud of my LLM model

She can learn from youtube scripts which is pretty cool and just from me talking to her

[olive sable]

its jax

[tacit sage]

lol I should probably change my pfp to something for fitting for what im doing

anyways

[olive sable]

im not that far into TADC

im liek at ep4

[tacit sage]

its a good show

ok so the next logical step clearly is to now get her to try and interact with me without me interacting with her

[hard raptor]

Imma convince the dutch government to invade flanders

just to spite sam

[olive sable]

honeslt

i would welcome them

we could have decent roads

[tacit sage]

im in my "Give the A.I a muffin when its doing something right" arc

[olive sable]

the lenses are giving me some issues

lemme think about this one for a bit

preferably id need to put a short throw on it

[azure lynx]

could you make like a 1m tall tube to hold everything so the throw was right?

and sit it on the floor?

[olive sable]

the minimum distance is 50cm

so that coudl work

i jsut dont really wanrt it to be a 50cm + 10cm actual screen + 20cm space inbetween lens and bottom

[azure lynx]

you could also deal with some of the distortion from not being fully collimated in software by distorting the image you're projecting

but would still need it focused

[olive sable]

ye

[azure lynx]

you could maybe do it so it stands on the side of the projection cylinder?

like the whole thing lies down

[olive sable]

hmm

[azure lynx]

then it could still fit on a desk, but just have a part that sticks out the side

[olive sable]

then it would jsut be very long

[azure lynx]

easier to not knock something very tall over when it's already lying down

[olive sable]

the one i got has

Throw Ratio: 1.2
Off Axis projection: 100% Offset

so id already need to correct for that 100% offset

cuz now the bottom of the image is at themiddle of the lens

i think i need to get rid of the stock lens and put a different one on

but they dont have standart lens mount, so id need to 3d print

on-axis woudl probably be easier to design for, but 100% off-axis might actually make it use up less space

[olive sable]

i can put a spacer inbetweent he lens and the DMD to make the focal distance closer

[tacit sage]

I just spent the past 2 hours trying to get tts to work

just in time for my psychology appointment lol

Will I be diagnosed with ADHD tune in next time to dragon ballz

[olive sable]

i diagnose you with brain't

[tacit sage]

lmfao

[neat patio]

Its bananas B A N A N A Z

[tacit sage]

ok but like genuine question whats the like legality of me making my own streaming A.I like neuro

[unkempt citrus]

There are others around, you'll be fine

You just probably won't be successful

[tacit sage]

thats fine not really looking for success

[unkempt citrus]

Then go for it

[olive sable]

as logn as you use a filter and dont forget certain periods in history

[unkempt citrus]

[tacit sage]

certain periods in history..

oh

lol yea thats a good point

wait theres also other people who are also already streaming with an A.I their working on?

is it like an entire category?

is there a way I can view these people as well

its lowkey perfect that theres also other people who are doing what vedal is doing so I can see what they are doing as well

[olive sable]

throw ratio of the original proctor lens is 1.2
the DMD width is 9.855mm
9.855 * 1.2 = 11.826mm

at the 50cm factory limit we have s = 1 / (1/11.826 - 1/500) = 12.113mm from the DMD
we want to get 10cm so we do s = 1 / (1/11.826 - 1/100) = 13.412mm from the DMD

so i need to 3D print a 1.299mm spacer

1.299 mm is not too bad

for 5cm i can do 15.489mm

nah i forgot the - 12.113

i only need 3.376mm

actuallly. i probably need to balance the focal plane with the size we want

[unkempt citrus]

There's been a few that try every so often

Most of them never get noticed

I can't remember any of the names of them though

[azure lynx]

i feel like there was a kind of corpo one in the last year or two which made an initial splash but disappeared quickly. but otherwise it's probably just people playing at it hoping to become the next vedal on twitch.

they probably just need a lucky raid

[olive sable]

for a throw ratio of 1.2. we need the fresnel to be exactly 180mm away for 150mm of light

s = 1 / (1/11.826 - 1/180) = 12.658

12.658-12.113 = 0.545mm

[azure lynx]

how wide is the focal plane? how blurry will it be on the top and bottom when the middle is focused?

[olive sable]

the goal is to make the focal plane 150mm wide

at 180mm form the lens we'll put a fresnel

i just need to put a 0.544mm spacer inbetween the lens and the DMD assembly

[azure lynx]

it would be funny if a 3d avatar had to squat so you could see their mouth moving coz it was blurry at their head and feet

[olive sable]

0.545mm layer is pretty exact to get right tho. idk if my ender 3 could pull it off

[azure lynx]

do you have something to render the slices yet? it'll be less straight forward than just slicing on a horizontal plane because of the helix. you'd be able to test if it was working by setting a video of it like you'd use as the color source for a light in blender. (i think a spotlight?)

[olive sable]

im probably better off jsut putting some pieces of paper inbetween

[olive sable]

ive been looking into how to do it wiht vulkan, but i odnt have a working solution yet

[azure lynx]

you just need to calculate the depth value for each (x,y) coordinate, and then lookup/calculate that pixel's value.

[olive sable]

the lookup is the issue

i cant do traditional rendering

i need to have the model already be voxels

[azure lynx]

the "easy" way to do is to voxelize it.

[olive sable]

ye

[azure lynx]

the better way might be with SDFs or other implicit surfaces

then you could have proper smooth surfaces without marching cubes-like approximations

the middle ground is to write your own triangle raytracer for a mesh

[opaque wharf]

The Z is pretty accurate

They can pull 0.1mm layer quite welll

[azure lynx]

you'll have to make the layers custom heights probably though

or it'll round to the nearest layer

[opaque wharf]

The resolution of ender 3 is 256 step / revolution and 2mm pitch thread right?

[olive sable]

idk

if we do that. with the fresnel lens we shoudl get close to this

there's still the issue of the 100% offset tho

i think its fine to jsut put the projecotr offcenter

ill need to research it more

[solar pilot]

I so need to get myself a new printer, my poor Anycubic i3 from
Uni is dead :(

[opaque wharf]

Yeah, I've checked the spec and ender 3 can pull off 0.04mm because a single step is the thread pitch / step per revolution

[olive sable]

[opaque wharf]

Make one from scratch

Honestly, I wish I did that instead of buying ender

[azure lynx]

i'd maybe worry about how the heat from the projector will affect the 3d printed part though. they tend to have low melting points

[opaque wharf]

Now that I have a lot of experience, ender is quite shitty without tweaking

[azure lynx]

instead of making one from scratch, consider a bambu A1

[olive sable]

this thing rn is 10cm electronics, 18cm cone dispersion, and 10cm acual projection surface
we can make the projection surface as tall as we want within some limits. but im not really happy with the current height of the red cone dispersion part

this design 48cm tall rn

[opaque wharf]

Or that. But it's too pricey if you want to have a good cnc

[tacit sage]

Thankfully Ive already convinced myself im not looking for fame with this one also sorry for the late reply I was in a psychology appointment 😛

[solar pilot]

Do you have a good ‘from scratch’ example? I could obviously reuse most of the stepper motors from the anycubic but with better drivers etc

[opaque wharf]

Because now I know that I could make a rigid frame and just change toolhead and bed as necessary

[opaque wharf]

Nope. That is honestly come from experience. But basically if you only need 3D printing, check out klipper

[tacit sage]

Also should I use a LLM different from ollama? I was told its good to like start with but is it good for like a result tho

[opaque wharf]

But I want to make PCB so I need a place to etch (enclosed chamber with heated bed), to drill (change to drill toolhead), and then make a case

[olive sable]

true.
i think i might not want to make it from plastic

[opaque wharf]

Throw in a laser and you also got laser engraver

[olive sable]

i have a laser

[opaque wharf]

Laser to cut

[olive sable]

mine is a laser to etch i think

[opaque wharf]

Yeah etch sorry lol

Damn that's nice then

[olive sable]

its a cheap one

havent used it actually

its just been sitting here

[solar pilot]

How many mW?

[olive sable]

lemme check

[opaque wharf]

With some luck, you may even be able to etch PCB on those

[olive sable]

1.6W

its the lower end one from creality

[opaque wharf]

Naw, scratch that. It won't even make a dent on the surface lol

[solar pilot]

Teddy says hi!

[olive sable]

its more for wood and such

[opaque wharf]

Yep

Still nice to make gift tho

If you have a spare stepper, you can even make engraver for round objects

Etcher*

[olive sable]

i think i need to account for the 100% offset by using a 300mm fresnel

then ill cut a piece out of it

[unkempt citrus]

If you just want cheap to get shit done

Bambu labs is cheap and works

Personally I'm in the process of slowly making a Voron

[azure lynx]

that's the main thing i like about my A1. it pretty much just works most of the time.

[unkempt citrus]

I bought my ender 3v2 before bambu was in the market

[olive sable]

my ender 3 is an absolute peice of shit

but it has a bunch of upgrades

so now its manageble

i put like dual z axis, some smart functions, a cr-touch

[lyric salmon]

I just coded an entire application. Only to find out I was using the wrong version of Python

Wait, I can probably still make this work

[olive sable]

python versions are pretty interchangeable

as long as its not pytohn 2 to 3 or whatever

[lyric salmon]

NVM

I GOT IT TO SWITCH VERSIONS AND WORK

We prayed for moments like this

[glad path]

minor versions are usually backwards compatible, or at least not breaking

[olive sable]

ye

its ussualy just some minor changes

the biggest issue is the libraries most of the time

[glad path]

yes

[opaque wharf]

Cheap my ass. That is a whole 1 and a half months of salary here

[unkempt citrus]

Compared to a prusa?

[opaque wharf]

The problem with the ender 3 is the rigidity and the hotend for more high temp filament. You fix both of those, the rest is QoL.

[opaque wharf]

Both are expensive

[unkempt citrus]

Sure but its relative

[opaque wharf]

You compare that to ender 3 v2 and it is even cheaper then

[unkempt citrus]

Theyre about the same price here

[opaque wharf]

Nope, they're different here by a wide margin

Iirc, prusa is even more expensive than bambu

Anything not from china is expensive here

China, Korea or Japan

[azure lynx]

3d printing can be expensive. if buying a 3d printer is a major investment you might not be ready for the ongoing filament costs.

and if you think "i won't use much filament", you probably shouldn't be buying a 3d printer

[opaque wharf]

Allow me to demonstrate

[olive sable]

the filaments i print dont need more temp. im fine with how it is rn

[opaque wharf]

And yes, the bambu price is with the ams

[azure lynx]

compare it with a bambu A1

which is the equivalent printer

maybe even the A1 mini for the prusa

[opaque wharf]

Alright, lemme check

[azure lynx]

coz you're comparing a bare bones printer to the combo with the multi-filament add on

and the enclosure

[opaque wharf]

They don't have prusa mini here. Only mini+

1 mill idr difference between the ender and bambu still. Then there's prusa

For reference, minimum wage is 4.5 mill idr / month on big city

[azure lynx]

they're not "impulse buy" cheap unless you have a high income.

[unkempt citrus]

For Bambu I usually mean the Bambu A1 mini

Oh wait you have it there

Huh so it is cheaper

[opaque wharf]

I am lucky enough to have a high income, but that doesn't mean I can spend it willy nilly either. For reference, I can make a better frame, hotend, extruder, electronics, and all that jazz for 5 mill idr

[unkempt citrus]

Yeah but the average person whos complaining that their school's 3D printer is broken isnt going to be able to do that

[azure lynx]

the bambu is designed for people who just want something they can use immediately with good results.
the default settings are (imo) way too conservative for most materials. but they work perfectly adequately out of box without needing to modify anything. (I did add a clip on box to catch the filament it poops when changing filament and initializing prints, but that was only to keep my desktop clean. if you ignored the multi-colored plastic poop all over the desk it was perfect.)
and you're paying for that experience.

[olive sable]

EKB says the throw ratio is 1.2, but TI says its 1.4.
so in reality i cant actually design anything for this without knowing for certain

[azure lynx]

design for the worst case?

then if it's the other you can probably just cut a section out

[olive sable]

i mean

thats not really how throw ratio works

its kinda the angle of the output beam

if its too small i dont have my fulls creen, if its too big than half my pixels wont be visible

[opaque wharf]

Design it with adjustability in mind

[azure lynx]

you can just move it forward or backwards to compensate, no?

[olive sable]

ye

i guess if it ends up being too small ill need to extend the size

its not a massive issue, but kinda annoying to design lens optics for

[opaque wharf]

Try to overlay both designs on your head and see where they differ. Then make that part adjustable and fixing everything else as much as you can

[azure lynx]

all optics are annoying. things would be so much easier to make if light just behaved like i imagine it should.

[olive sable]

if the pixels were jsut 1 line of light

thent his would be so much easier

but they change in size and now i need to make sure they're in focus

[glad path]

if i had a penny for every time i called chatgpt out on this i might have half a dollar now

[glass jetty]

dont accept any generated code

just write it yourself, even if line by line

at least you may spot shit like this
at most - better names and formatting

• dont give ai context it shouldnt have to find solution for problem, it reduce chance of hallucinations

also, gpt now is just worst for code

i use lmarena -> thinking models (whatever)
and somehow 50/50 correct/total_bullshit

could be 20/80 if id try solve everything with ai first

[azure lynx]

so you think it will mess up the easy stuff more than the hard stuff? (i'm assuming you don't only use it for the trivial stuff)

[glass jetty]

i only use it for trivial "is there any, or what is function for this"

it is only usecase

and it do it wrong usually

you have to check docs

[amber fractal]

the C++ to C++ in the bottom left is so real from what I hear about it

[azure lynx]

every language sucks. but some are useful for some tasks.

[young plover]

C++17/20/23 <-> C++03

[azure lynx]

    Single voice can be requested (e.g. 'af_bella') or multiple voices (e.g. 'af_bella,af_jessica').
    If multiple voices are requested, they are averaged.

Ok... that sounds like a feature which could do with more documentation. Also more control. But cool.

so you could do a 2:1 blend by putting the voice in twice

[glass jetty]

yes
it is real

i lost ability to cry how msvc is bad in prev server, so i will cry about it here

there is regular function, that have one compilation error

one error

instead, fucking worst compiler give me error highlight for every single line

and also give unreasonable error msg

same func but fixed namespace for one type

really, worst compiler
and it is light error by msvc

it can give you unreasonable error inside meta in std

and you have to guesswork where is error if you changed many files at once

[azure lynx]

it's usually the first one. and that cascades.

[glass jetty]

most of the time, tho, in console output there is actual error stack, but 2 times that was just error and nothing related to code in my app

[glass jetty]

clang and gcc handle it much much better

and you know what? msvc is windows compiler
windows have much much more users
that means it have more developers

but

msvc is worst compiler

also

windows exceptions

fuck you microsoft

[azure lynx]

they don't want you to like it, just use it.

[glass jetty]

i removed all exceptions from project completely
because after transition from linux to windows... it undebuggable

[glass jetty]

except recursive algo for one edge case, i used exception to unwind stack instead of tl::expected

ok

we really should use only vue and cpp backend instead

[jagged turtle]

honestly I don't get why RSC is the way it is

or even why it's ncessary at all without just, idk, rendering to string or smth (however preact-render-to-string goes)

to be fair, supposedly RSC isn't super stable for bundler/framework implementation

https://react.dev/reference/rsc/server-components

oh and also this

yeah I'd say this is pretty good instead of server components

Hello guys, I am planning to uninstall windows now, and plan to install Linux os. Ubuntu is the only linux I have ever used. Could you give me any recommendations which is best for both software development and gaming

[rough bloom]

distro war incoming

[fleet jungle]

Why not go with SteamOS or a unofficial alike of it?

Seeing as you're a programmer, I'm sure you'll do just fine enabling the locked permissions of bazzite anyway

[tender river]

steamos very much not desktop distro

[rough bloom]

CachyOS is good probably
it's basically preconfigured Arch Linux with a focus on performance

[fleet jungle]

It's not?

Oh guess not, seeing as you have to go through some steps to get a desktop view, while its natively a programOS

idk what those are called - OS that basically only runs one main program with limited freedom in GUI

[tender river]

its just not intended for desktop use image based os

[short barn]

Hmm, let me check, I plan to install on tuf gaming laptop

[rough bloom]

I think most (modern and common) distros will do both dev and gaming just fine though, Proton is mostly self-contained and pretty much just needs working graphics drivers
same for dev, nodejs/npm doesn't really care about your host OS

[fleet jungle]

have fun with nvidia tho 😩 (I say from experience)

[rough bloom]

ye image based probably sucks for power users unless you love containers

[fleet jungle]

who loves containers

sorry, they have their purposes

[rough bloom]

pretty much everyone ships NVIDIA drivers
it's fine, they work

[fleet jungle]

I mean who would want to daily a container

[fleet jungle]

setting up for them was a... challenge tho

[tender river]

works for many people on steamos and bazzite and silverblue derivatives

but the difference is

[fleet jungle]

😐 I just realized what that meant and I was recommending that to the other guy

[tender river]

steamos is literally just intended for use on consoles

[fleet jungle]

I was thinking of docker containers, but are those maybe fine to run like OSs too?

[fleet jungle]

interesting

[uneven pulsar]

sql queries are sluggish

[tender river]

???

[rough bloom]

[fleet jungle]

hmm has Vedal set up the streams to have custom emojis beyond what twitch offers?

[uneven pulsar]

kind of stinky the only conventional way of managing databases that's compatible for every device old or new

[rough bloom]

uses 7TV

[fleet jungle]

I've seen the doc emojis being used but Idk if that's functional on twitch itself

[rough bloom]

they aren't always the same between Discord and Twitch but IIRC this one is

[fleet jungle]

oh thats neat

[fleet jungle]

wdym

[rough bloom]

there's no integration between Discord and 7TV, it's all manual

[fleet jungle]

oh yeah

No surprise there

I think discord parted ways a while back from them

[uneven pulsar]

I hate this

That's just so unnecessary by conventional meaning

[uneven pulsar]

Another weird ahh sql query

[stuck ocean]

fedora is good its the first os i used after switching to linux

Anyone for a chat ? DM’s open

[frozen hollow]

They use terms like generous and ample because they have literally no idea how much they’re willing to give you when they make these things.

[opaque sigil]

you will take what you are given and you will be happy about it

[wary mauve]

Quick question, can "role" technically be anything? Attempting to give my ai game context, at the moment its just user messages, but it very much hates responding to what is being sent, as it adament on commenting on the game context only 😭 i know i can tweak this with a "game" prompt when a game is active so it knows what to do when a game is being ran, when to comment and to prioritise answerinng / talking to people even whe a game is active but just curious if i can set role to something like "game" or "context"

[frozen hollow]

gotta go nyarch linux for the lawls

got that on a VM on my backup PC xD

[short island]

so..what's this?

[muted jasper]

Your question seems to lack context, can only guess what's the actual problem

[muted jasper]

Your question seems to lack context. So the answer is "It'sa me, Mario!" Hope that helps

[uneven pulsar]

Software development and gaming?
Nobara
Fedora is well known for its suitability for software development
Nobara is based on Fedora but has more added features and optimizations for gaming

[stuck ocean]

and uh do not trust anyone that mentions arch or gentoo

[stuck ocean]

nyarch is peak

if only it had hyprland support

[rough bloom]

Arch is reasonable
Gentoo is...

[stone badge]

i am reading a DSA book so was wondering if i should take notes of the algorithms, or just try to understand the logic and try to implement them myself

idk whats the best approach

[wary mauve]

don't worry, got it all fixed, it seems like it really liked responding to only the newest message

however I do have a specific game integration issue with one of neuro's game, specifically platinum, seems like it cant read memory addresses good enough

if anyone knows anything about the platinum integration 🙏

[tender river]

apply them

competitive programming tasks are the easiest option

obviously just vaguely knowing what is possible helps, but its best to do something with what you learned to confirm you actually learned it

[glass jetty]

nah, who need any war, every one know that arch is best, debian for servers, and canonical's shit for industrial

webp and avif - newer

[patent shard]

webp is barely better than gif, tbh

it's still pathetic even compared to H.264

people always wonder why my gifs are so high quality, it's because I'm not using garbage formats

[frozen hollow]

Webp turned my 350kb png sprite sheet of 1024x1024 simple art into 75kb so they’re alright in my book

[patent shard]

for static images, it's fine
I'd still say its lossy compression is not good.. I only use webp for the lossless function
but animated, it's abysmal

[frozen hollow]

I basically just wanted jpg with transparency and it seems to fit the niche

[patent shard]

biggest issue I have is it only supports 8-bit [per channel] which is... kind of wild?

[hard raptor]

i think i have PTSD towards JS now

purely because the virus i got on my pc yesterday was written in JS

OCZ Vertex anyone

[olive sable]

goodmorning

[azure lynx]

hello! I saw this video and thought of your projector project.
if you change the volumetric thing to being your helix you can do visualizations to check that the video you want to project works in Blender.

[azure lynx]

next month's.

and the next.

[idle dune]

Yeah I know, I'm just memeing

I'm with Bell Aliant which is like THE Canadian ISP monopoly

[azure lynx]

hmm. i should change my phone plan.

[idle dune]

I got mine changed because I was with Lucky Mobile, but they offered me a promotion to switch to Bell and have all my credits carry over.

I bought a used 512gb S23+. I need to find something to do with my iPhone 13 now.

[azure lynx]

an AT&T person came around a few days ago. he knocked on my door to tell me that in a couple of weeks i should have better cell service. was weird that they weren't trying to upsell me anything.
i bet they'll email me and text me about it too. but the signal here is literally unusable without wifi-assist. like 1-bar.

so as soon as i get out of wifi range my phone will cut out if i'm walking to my car, until i leave the parking area of my apartment.

[dim inlet]

Hi

[olive sable]

Hi

ive done the math

we can use a biconcave lens to make the angular spread of the light faster

but we need to put it at roughly 45mm from the stock lens

that in itself shouldnt be too much of an issue

then the distance to the fresnel depends on the strenght of the biconcave lens

if we get one with FL of -50 we can put the fresnel at 50-55mm away

so that gives us a full lenght of roughly 10cm

its that small, but its better than 18cm

actually, i fucked up my math

i was using the width of the DMD, not the height

so we wouldn't have gotten the full circle

[gritty dust]

Sam, exams are finally overr

we have successfully done physics and religion exams

[olive sable]

religion exam

You just have to believe

i will def go to hell

but its warm there so eh

our schedules have been made for next semester, nothing on friday

[gritty dust]

must be nice not being in highschool

[olive sable]

it is yes

[olive sable]

need to use 6161.4μm, not 9855 μm

half angle is 12.6 degrees then, not 19.6

1140 micromirrors
6161.4 μm
by
912 micromirrors
9855 μm

so when we crop it to 1:1 we're losing pixels from the 912

orthogonal micromirrors are so much easier to calcualte

cropped to 1:1 we get approximately 713x1140 pixels

new plan

1054 x 659 pixels for max refreshrate

im beginning to think

[opaque wharf]

Took you a while to do that eh?

[olive sable]

my 1 brain cell is not on vacation anymore

my firefox pages keep crashing

grrr

lemme restart my pc

i fucked up the math somewhere

okay ye

its 570x1140

exactly half

[amber fractal]

2:1 ratio

[olive sable]

its because of the daimond layout

the ones inbetween only count towards the height

so in theory the height being double wont be what we see in the actual screen

aslo

goodmorning iggly

[amber fractal]

[olive sable]

we can actually use the full 1140x570 pixels

its within our hdmi bandwidth

[amber fractal]

Insane how this is all put together

[olive sable]

im gradually losing my mind

[amber fractal]

I can relate

[olive sable]

[amber fractal]

This rabbit hole feels exactly like my NN work

[olive sable]

the closer i get to a final design, the less clear things become

[amber fractal]

As you spread out you realize your foundations never existed in the first place and only the knowledge from the black box persists

[olive sable]

ye

you think there are some starting constants, but then you realize those never existed and you need to actually calculate them

since we're working with out DMD 1:1 ratio of 6161.4 μm x 6161.4 μm, and throw ratio of 1.4 of our stock lens, the 150mm final image would be at a distance of 107.14mm

i need to actually see if that matches up with the specs

[amber fractal]

I think I am somewhat rested enough to continue with NN again. This is going to be a grinding time

[olive sable]

goodluck

sqrt(9855^2 + 6161.4^2) = 11622.6.
so the 16.7 inch at 50cm distance is 424.18mm diagonal, so 424.18/11.6226 * 6.1614 = 224.86mm high

thats not right

i forgot a decimal point

so 224.86mm high at 500mm distance.
thats not nearly throw ratio of 1.4

oh

throw ratio uses width, not height

vertical throw ratio is 2.223

[olive sable]

this is jsut completely wrong cuz of that

real distance usign vertical with stock lens is 333.5mm

with a biconcave D11mmF-8.58mm lens, we can get that down to 113.5mm

if i use 2 i might get it down to 64.3mm

[olive sable]

i cant find a 300mm fresnel lens with a focal point closer than 120mm

effectivly thats our minimum size then, so we only need to use 1 D11mmF-8.58mm

we could also use a larger but less strong lens to give some wiggle room

fresnel lenses are the ones that burn peoples houses down

[dusky jackal]

Hey. I got dm’d by some random on a mutual server that I’ve never been active on.

Is it safe to tell them that I never spoke to them and don’t DM me out of nowhere before blocking them, or will typing anything be dangerous?

[olive sable]

i mean, typing should be fine

i just wouldn't

[dusky jackal]

Oh. I was told never to say anything for some reason.

[olive sable]

the responding itself isnt dangerous. its the stuff that follows

this ussually results in phising, or artist scams, or whatever

[dusky jackal]

i jus wanded 2 tel them they r a bad preson a not 2 due bad preson thing or I will call the 911 peobal

[dusky jackal]

Lmao yeah.

[olive sable]

ok i have everything figure out now

i think

[opaque sigil]

famous last words

[olive sable]

we just need to put a 1mm spacer in-between the stock lens and the dmd assembly for focus, then we have a D15.5mmF-9.9156mm biconcave lens, and then a 300mm fresnel with 120mm FL at the end

out of which we basicly have to cut a 150mm circle at the edge

[amber fractal]

bro what flavor of jank is this???

[olive sable]

[amber fractal]

how is python deconstructing the array here?????????????????

what in the frick is actually happening

[olive sable]

uh

ye i have no clue

[opaque sigil]

val |Red()== wtf am i looking at

[amber fractal]

Some jank op

[olive sable]

maybe try using brackets?

i have no clue what the order of operation for that is

[amber fractal]

let me make sure the == isn't being handled as a spacial case

because most examples doing __ror__ and __or__

nope

python is deconstucting it somehow

mask isn't a bool... It is a bool array

[olive sable]

[opaque sigil]

elementwise bitwise operations?

sounds like something numpy would do

[olive sable]

thats a mouthfull

[opaque sigil]

since you can also do things like 2 * array

[amber fractal]

the whole point of this was to use this as an alias

[opaque sigil]

wait where tf is bitwise_or.reduce coming from

[amber fractal]

that is the thing I wanted to alias...

I can already do the others fine

but if I wanted to swap the codebase to using non functional

then those would still be functional because there is no way of doing those non functonally

so I am doing this to lessen the blight those would cause

[olive sable]

this is our current design

discord embed making it square

i feel like its still really tall

but i cant find any optical parts to reduce the red segment

[amber fractal]

python

why is that I can only use or

as the operation of the second half

not even operations like add work

[olive sable]

ask chatgpt, im too dum

[amber fractal]

yeah I'm also dumb, but I did learn of a part with it

numpy has an overide which I am now taking advantage of

[olive sable]

i used my 1 braincell to death trying ot design the lens assebly

i shall now take a break

[amber fractal]

good news is that I can at least set the left op to whatever I need it to be

[olive sable]

i need to design the vulkan side of this projector system now

welp, ill need to learn voxel raytracing

or not even ray-tracing, more like we know the distance and just need to read the value of that location

irlX = x + 0.5·(y mod 2)
irlY = floor(y / 2) + 0.5·(y mod 2)

this layout is gonna suck to program for

[amber fractal]

edit, at the cost of reduction, this is the most cursed thing known to man

what in the actual frick is this function, the more I edit I can make it better but also I have so many questions on how

Alright, it works

the enum is absolutely necessary for functionality

one can't do a lambda and pass it in

someone give me a reduce symbol

mabe I'll use APL's reduce symbol

the price we pay for nice looking code

[potent birch]

[glad path]

ok erm

i have the most annoying bug to plague me in quite a while

so i need to record keystrokes

im on macos

right

and im using python

i have a hotkey listener thing and a callback

the callback starts another keyboard listener

but

that's not allowed

all the listeners need to be initialized (i think) and started in the main thread

and the callback isnt the main thread

if i dont do it in the main thread the os immediately sigtraps the whole application

and I cannot figure out how to do it without rewriting half of the codebase

"patch tuesday is now a dreaded experience for people everywhere as they wait to see how their operating system gets borked in new and creative ways"

[azure lynx]

"patch tuesday" has been around for like 20 years, hasn' t it? for windows anyway.

[olive sable]

ye but it used to actually patch stuff

now it does the opposite

[azure lynx]

no. it's alweays broken stuff.

that's not new.

[olive sable]

it was never nearly as bad as it is now

[azure lynx]

and kids used to listen to their parents.

[olive sable]

no they didnt

[azure lynx]

i know. same thing. it was always this bad.

[olive sable]

no

[azure lynx]

i'm old. i remember.

[olive sable]

has there ever been an update before that made the boot partition completely unmountable?

[azure lynx]

https://bbs.archlinux.org/viewtopic.php?id=302091 <= if you dual booted, yeah.

last year

and 7 years ago it deleted Linux occasionally.

[olive sable]

thats the efi, thats different

[azure lynx]

there have also been updates which made drivers not work before so some computers couldn't start.

[olive sable]

grub efi != unmountable windows boot partition

[azure lynx]

windoes boot partition IS EFI

unless you mean the system partition

[olive sable]

the grub efi thing still happens

but we're talkign the one for windows

[azure lynx]

it didn't do it for everyone though. just specific hardware was affected, right?

[olive sable]

idk

[azure lynx]

coz it didn't do it to me

[olive sable]

UNMOUNTABLE_BOOT_VOLUMEso the C drive

[azure lynx]

or anyone i know personally

and if this was the first time this particular thing has happened, it seems like it's not an "always" problem.

[glad path]

does anyone know a workaround to this

[azure lynx]

try setting a flag in the other thread and checking it in a loop in the main thread?

then do the thing from the main thread when it's set?

[glad path]

that would block the main thread though

i think

maybe

but i don't want high cpu usage

[olive sable]

uh.
is there a reason you cant jsut have one keyboard listener?

[glad path]

because i'd need to rewrite a ton of stuff

[olive sable]

then i dont know

[azure lynx]

sounds like you need to rewrite a ton of stuff anyway

[glad path]

i mean

the code is public if you want

[azure lynx]

i don't want.

sounds like bad code.

[glad path]

it runs fine

but not as an app

[azure lynx]

except it doesn't work.

[glad path]

it works unless it's an app

and also i only started trying to make it build as an app today

[azure lynx]

so what's the problem? ;P

[glad path]

macos doesnt like it when its an app

so it kills it

[azure lynx]

then rewrite it. seems simple. "if it works by itself it's still usefess coz you want the app."

i've told you the basic trick for multithreaded thread launching. now you need to work out the details.

you pass a message to the main thread and have them do the thing from the main thread.

[true hemlock]

got more offer

$250 for titan v

[olive sable]

i cant tell if thats a good deal

[true hemlock]

and about $3000 for a threadripper 9980x es

[glad path]

the cleanest way to do that is signals but that doesnt work

[true hemlock]

should i take

[olive sable]

the titan V doesnt really seem worth it comapring to 3090s

[true hemlock]

unless if your workload require fp64

[olive sable]

the threadripper is a good deal comparing to msrp, but still really expensive

[true hemlock]

the only reason im considering that titan v is because the fp64 and hbm memory

[olive sable]

only 12gb tho

but the bus width is really big

[true hemlock]

though its about 3070 level so $250 is pretty cheap if it were a normal card

(and volta is overclockable af elvyn once got the titan v perform like a 3080)

[olive sable]

3072bit bus

[true hemlock]

3090 is miles better for people wanting to do ai

but titan v is miles better for hpc

[olive sable]

for those of us who dont know

what is hpc?

[azure lynx]

high performance computing

like big number crunching

[olive sable]

[true hemlock]

and its usually scientific computation/simulations

so you need that fp64 precision

just a tiny imprecision fucks up the whole process

[azure lynx]

"let me simulate the galaxy using 4-bit precision. close enough."

[true hemlock]

nvidia ahh

[uneven pulsar]

Evil mentioned at some point in the subathon that she wants to build/has an operating system called "EviOS"
would be interesting to make a Linux distro called that

[glad path]

"minor rounding error"

[true hemlock]

its also why i called the B300 e waste

because they took out the fp64 and all in on fp4

makes it useless for hpc

fp4 is also unusable anyway

[olive sable]

[errant flax]

the one w the 4090?

[eager echo]

Idk but I think is run on another pc

[azure lynx]

there used to be components which were cloud, like her voice, right? Ashley from Microsoft Azure was cloud right?

[errant flax]

yeah

says that on the wiki

[glad path]

her voice is ashley but pitched up a bit i think

[eager echo]

How can she play osu?

[azure lynx]

that is a completely different system really.

she plays other games with patches in the games that allow her to interact in various ways. but the OSU Neuro is completely different from the VTuber Neuro.

[eager echo]

OMG I'm new

[azure lynx]

(i only learned about her well after her first birthday so I don't know all the background)

[eager echo]

At least more than m

[azure lynx]

while it's completely different code it is the same author and same name and twitch channel. as far as i understand it, neuro the vtuber was initially a bot to keep people entertained while the OSU bot was playing or something?

[glad path]

completely seperate ai

[opaque wharf]

Wtf

Useless compute unit

[silent island]

chat, do u think I need an additional 1tb nvme if I already have 1tb of onedrive storage?
I mostly code on vs and vs code and play a bit of AAA and switch games with my emu

[glad path]

no

i have 1tb of disk space and i havent ever ran out

[faint sandal]

yes

if you ever question if you need more storage the answer is always yes (if you can afford it)

[opaque wharf]

Modern AAA or old AAA?

Because some of those games could reach 200+ GB easily

[silent island]

PS4 era games recently ported to PC, like tsushima, FF7R, P5R, P3R, etc.

[amber fractal]

I'm sure everyone in this chat appericates my handywork

[opaque wharf]

Well, depending on the number of games, then I suggest just buy another

GoT alone is close to 100GB IIRC

[opaque wharf]

I don't appreciate python in general

[amber fractal]

yeah, I don't want to be in here either

I'm only here because it is a lot easier to prototype logic

I'm deciding to make the final iteration in C so I can use it as a lib

I should be able to allocate everything I need ahead of time

[frank mauve]

would linear algebra help with AI stuff

i mean im sure it prob helps a little but was wondering to what extent

[opaque wharf]

Math in general would help. Specifically statistics. But yeah, linear algebra would help to wrap your head around some concept too

[frank mauve]

statistics?

[amber fractal]

Transformers is based entirely on derivatives as well

stats make sense

dealing with data

[opaque wharf]

Yes, to understand the data that you will be working with

[frank mauve]

im taking statistics right now so i could probably apply some stuff im learning

[opaque wharf]

You may be already familiar with some "AI" stuff then. Namely, parameter prediction or whatever the name is that I forgot already

Basically inference statistics and bayesian

[amber fractal]

optimizers

[frank mauve]

the stats im taking isn't really related to AI though

I think its just stats in general

[opaque wharf]

Well, the concept of parameter estimation is in general statistics. So does bayes

[frank mauve]

oh i see

maybe my class hasn't gotten there yet

[opaque wharf]

Yeah I think mine was in statistics 2 or 3. It was at the very end of my study and used for QC stuff

Because I major in applied/engineering degree

[frank mauve]

quantum computing?

[opaque wharf]

No, mechatronics engineering

[frank mauve]

mine is just AP stats

[opaque wharf]

So I don't get much in depth knowledge from uni, which is why my stats class only goes until bayes

[frank mauve]

bayes is the one about probability of A given B or something like that?

[opaque wharf]

Yep

But it also depends on what you want to do with "AI"

If you want in depth understanding, then math is the way to go

[frank mauve]

oh yeah i remember that then lol

[opaque wharf]

But if you want to just make stuff, then CS and programming because most of the math is abstracted away. It does help when you're building a model but not by a lot I think

[frank mauve]

i think i kinda wanna do both

im sort of washed at python though since I haven't used it in a while

[opaque wharf]

Yeah, at least you can practice python anywhere through google colab

[frank mauve]

i guess ill also learn the math because I'll need it for physics as well

[opaque wharf]

Especially for AI stuff. But if you want to do local training, then someone else here is more knowledable

[frank mauve]

I'll probably do some training or fine tuning models

[glass jetty]

move this if to line 1984

[opaque sigil]

Ignorance is bliss

[glass jetty]

understanding ai

[opaque sigil]

NLP is pretty chill math wise thankfully

[opaque wharf]

Until you want to understand some older stuff like markov chain but yeah, not that heavy

Was it chain or model? Either of that

[opaque sigil]

Technically both no?

I forgot what the Markov property was about tbf

[azure lynx]

the model describes how the chain will form

[opaque wharf]

Same. I only remember the markov name lol. It has something to do with predicting future state but only from current state (disregarding past state) iirc

[azure lynx]

"past state" can be encoded in "current state".

[opaque sigil]

Funky state machine

It can but then it's not a markov chain duh

[azure lynx]

it can be implicitly encoded, which is why a markov language model can produce language like utterances.

[opaque sigil]

I suppose

[opaque wharf]

The NLP stuff that I know pre transformer is the markov model, RNN and LSTM lol

[opaque sigil]

Fun stuff

[rigid snow]

monka

a driver

[nocturne olive]

Classic WinRing0

[nocturne olive]

WinRing0 is an open-source kernel driver (I think) that basically lets any app that uses it manage kernelmode tasks from userspace
You can guess why that's insecure because as it turns out, letting random apps freely access the kernel, not just including the one that shipped the driver, is a very bad idea

[olive sable]

[nocturne olive]

WinRing0 used to be used by things like RGB and fan controllers I believe

[azure lynx]

this means there is an issue with the driver that a hacker could exploit to gain "Ring 0" or "operating system" level access to your computer.
it's not a virus but could be used by one.

[rigid snow]

i know what that is

i don't know the specific driver

but i literally did this

exploiting drivers i mean

[nocturne olive]

Fairly recently though it was added to Defender because Microsoft seems to want to reduce access to the kernel

[rigid snow]

definitely not to bypass any ac nuh uh

[nocturne olive]

WinRing0 is like the most exploitable driver in the universe

[rigid snow]

good

[opaque wharf]

At this point I don't know why windows don't just make a breaking change already to the kernel

[nocturne olive]

It's literally designed specifically to give developers an easy way to perform Ring0 tasks and a lot of malware use it to gain access to the kernel

[rigid snow]

i read what the driver is

you're not exactly correct

[nocturne olive]

Eh they've probably made many breaking changes "rewriting the OS with AI"

[opaque wharf]

Naah, many apps compiled with old ms compiler still work is a testament to their policy of not breaking backwards compatibility (mostly vendor program)

[jagged turtle]

yeah, for all its faults, windows is surprisingly backwards compatible

[azure lynx]

and ironically(?) backwards compatibility is the reason for many of it's faults.

[opaque wharf]

Which is why if they are now closing the kernel anyway, why not make it a breaking change altogether lol. But maybe they don't have enough manpower for windows the software anymore

[faint sandal]

replaced by PawnIO already

[nocturne olive]

Is it less insecure?

[faint sandal]

my friend wrote that from scratch

[jagged turtle]

because then "everything would break" and people would get mad

[rigid snow]

ok i read the code you are correct there are literally methods to read/write memory
i'm pretty confused though how is this still used and exists and got flagged by anything only now

[jagged turtle]

also because they already probably break the kernel by accident anyways because vibecoded os

[faint sandal]

and he grew up from the cheat scene

[opaque wharf]

People are already mad because of the update nowadays lol

[faint sandal]

he knows windows better than most EDR devs

in other words, yes

[azure lynx]

they could make the operating system perfectly secure, except you'd also need to buy new software to run. and people would need to compile it specially and make changes for the new system. lots of changes.

they do a middle ground

[nocturne olive]

Coolio

[faint sandal]

they already have

with the most renowned recent changes being hardware enforced shadow stack protection

[opaque wharf]

Naah, many software is subscription nowadays. It's on them to update those software then

[azure lynx]

i almost feel sad for hackers these days. used to be so much easier. ;]

[faint sandal]

which broke a lot of (badly) written drivers

[opaque wharf]

Good

[faint sandal]

VMP'd ones are the most impacted

i know because our EDR driver isn't CET compatible :)

[patent shard]

yeah, Fan Control switched to PawnIO

[opaque wharf]

At least it broke now rather than being a malware attack surface instead lol

[faint sandal]

there are still a decent number of workarounds for BYOVD scenarios

but the attack surfaces are getting smaller and smaller

[azure lynx]

access scope and other design errors seem to be a lot of them

[opaque wharf]

In a way, it is sad that people can't just run anything in the kernel willy nilly like linux does. But then, many linux people usually know what running in the kernel entails lol

[azure lynx]

when people could do that, they did bad things.

[opaque wharf]

I wonder how it would affect their embedded windows product. I remember the CNC from my uni (I think it was Hurco) has windows embedded on it

[faint sandal]

there are still some remnants of major issues with loading malicious signed drivers but with the appropriate ASRs applied it gets decently difficult

[olive sable]

the orange pi 5 ultra i had to reorder, but at least the cooler arrived

now i can cool what i dont have yet

[opaque wharf]

What happened now? They also out of stock again?

[olive sable]

nah the pi 5 order worked now

its just that i got a message that the cooler arrived

[opaque wharf]

Ohh, I thought you had to re order AGAIN after the first cancellation lol

[olive sable]

that would have been a pain

[azure lynx]

probably from the first order where it got cancelled?

[olive sable]

ye

the cooler and hdmi -> hdmi mini cable arrived

[opaque wharf]

I am quite lucky that the electronic store here is quite close now

[olive sable]

the projector itself is being shipped by the slowest ebay shipping in history, so thats for march

[azure lynx]

electronics store parts always cost like 3-5x more than they should.

[opaque wharf]

That's what you get if you order across the vast ocean usually

[opaque wharf]

Meanwhile its the reverse for online food delivery lol

[olive sable]

it was only 682 euro with shipping via ebay. while brand new was 1.2K

[opaque wharf]

Nice, almost 50% savings

[olive sable]

the fresnel lens will be PMMA

so acrylic basicly

kinda worried about getting cracks in it when ill have to cut it

[opaque wharf]

You don't have laser cut acrylic service nearby?

[olive sable]

idk, i dont think so

[opaque wharf]

Or maybe your uni has a laser cutting machine for their engineering dept.

[olive sable]

i highly doubt it

[azure lynx]

local maker space?

[olive sable]

if it exists i havent heard of it

[azure lynx]

hook up a cat toy laser pointer to a 3d printer and overclock it with a LiPo battery? [will not actually work. laser diode would explode.]

[opaque wharf]

Dang, your university doesn't have a mechanical engineering program?

[olive sable]

i have a 1.4W laser for my 3D printer, but the fresnel lens is 300mm in diameter so ouldnt fi on the printbed

[opaque wharf]

I think 1.4W is not enough to cut acrylic anyway

[olive sable]

ye

[olive sable]

nope

[opaque wharf]

Sadge

[azure lynx]

can could you potentially put one corner at a time in the 3d printer/laser-er?

[opaque wharf]

No, the 1.4W laser will not be enough to cut it anyway

To engrave something maybe, but not cutting. Or else it would take a very long time and the cut would not be clean due to heat build up

[azure lynx]

do a styropyro and overclock the laser?

[olive sable]

there is one a city over

18 euro per year

[opaque wharf]

That's cheap af. But the distance lol

[olive sable]

using the laser machine itself might also cost a bit

thats 18 a year jsut to be allowed inside

[opaque wharf]

That's expensive af

[azure lynx]

that's very cheap even for that here.

coz that would give you access to a base level of stuff once you've done the training for it with no extra costs

[opaque wharf]

"to be allowed inside" should be free lol. At least guided if you really want someone watching over that person

[azure lynx]

you can get a guided tour

but not use anything

and not like show up every week

[opaque wharf]

Ye, that's my point

To be allowed inside should be free

[azure lynx]

they want to limit that for liability. same reason it has to be a guided tour.

coz there are power tools and quite large machines

[olive sable]

its 18 a year to be allowed inside, acces to most tools, and some materials
other stuff is paid, they can hand out wood for free and stuff

[opaque wharf]

Now that makes more sense

You worded it like all of their equipment cost another fee to be used lol

[olive sable]

the big machines do

and you need to schedule when you'll be using it

[opaque wharf]

Yeah, that still make sense. But "to be allowed inside" is one hell of a word

[azure lynx]

it's very cheap. definitely worth it if you have some way to travel.

[olive sable]

its in collaboration with my college it seems
im geussing this is why they dont have machines on campus

[opaque wharf]

Indeed it is cheap because you get access to power tools and handtools you'd normally need to invest yourself. And if you don't do this stuff for a living, it makes even less sense to buy the tools

[opaque wharf]

Dang lol

[olive sable]

in terms of powertools i have most stuff just at home

[azure lynx]

it'd probably be worth joining and travelling out there just to get the lens cut

[olive sable]

true

[opaque wharf]

My uni has tons of stuff to use for their students. But they also have stuff that is rented for anyone (mostly companies)

[opaque sigil]

https://openai.com/prism/ huh

[olive sable]

ai latex

thats crazy

thats messed up

[opaque sigil]

Eh

[azure lynx]

also going to do that kind of thing is"socializing". so i can tell my parents "yes I got out and saw people this week."

[opaque wharf]

I have given up on using LaTeX. Typst is my friend now

[opaque sigil]

I don't mind latex tbh

Though typst seems neat

[olive sable]

laser-cutter, 60 cents per minute

[opaque wharf]

I mind due to how complex it is to setup and do anything with image/media

[olive sable]

they have their own 3d printers too it seems

[opaque wharf]

Do they provide assistance or give you full access to the machine alone?

[opaque sigil]

Is it? I guess media can be annoying true

tikz is my arch nemesis

[opaque wharf]

At least on arch, it is quite complex for my taste for what is essentially a compiler

[opaque sigil]

I suppose

[olive sable]

im not sure
