/general/@void how much free speech are you willing to permit regarding the use of profanity and racial slurs outside of clear racism?
On 4chan we usually got to go wild even outside of /pol/ and when you went full hitler you usually got a warning before a ban.
Obviously letting your site turning into stormfront 2.0 like 4chan isn't smart, it drives users away and destroys discussions.
Yet at the same time completely sterilizing everything defeats the purpose of anonymous posting here I think.
Also "tripfags" like myself should be held to higher scrutiny though since we can act as ambassadors for umigalaxy, right?
I'm asking because of the 4chan mod grapeape macking a mockery of 4chan just by posting the dumbest stuff on twitter lol.
Like I wonder if you should make different, more strict rules for registered users and relax them a bit for anonymous ones.
I'd be cool with that tbh. But if I made questionable statement (as anonymous while logged in) could the less strict rules apply?

/general/Why aren't people having kids anymore? Is there any way birth rates can be raised or is this the new normal?
Imo people are having fewer kids because they're marrying and even dating less often. A lot of people talk about money, but there's the least of the problems.
50 years ago most high school kids dated, nowadays only a minority do. Nowadays we have a lot more virgins and people who never dated.
Standards are sky high and people have no patience for human interaction anymore, guys would rather watch porn over pursing sex. Simping is rampant, be it the guy leaving likes on instagram, the guy on tinder swiping on a million women without getting a match, or the guy on twitch sending money to his dream gamer girl.
Girls end up in soft harems where 10% of guys fuck most women, they are told they need to marry a multi-millionaire while being broke, they are told their normal boyfriends aren't good enough.

/general/There's literally no place on the internet to discuss Magick and practical spiritual subjects anymore. Every modern forum on the topic is an overmoderated assembly of faggots, and every imageboard around is a basket case schizo central with no coherent discussion about it. Then you have the pseudo-skceptics (because they are not really skceptics, just retards shills) that have never in their god forsaken lives interacted with, and even less had any sort of experience regarding, mysticism and metaphysics.
Is anyone interested anymore? This is the conversation subject, but it has been propagandized with so much misconception and subversion that it set off people and everyone with real competent person participating and willing to share real perspective just fucked off. Early psionics and lucid dreaming forums, and the /r/DimensionalJumping and /r/Oneirosophy were good examples of competent online spaces, but their problem will always be that they are way too specific, and the ideal place would be a syncretic hollistically oriented place for all "magic" and mental science PSI phenomena. It's this topic just outright doomed in the dead of the internet? Subjected to be misunderstood by the masses and misdirected by helpless schizos? Is there hope for man?

Maybe that's just the way modern MMORPGs are, they play like everything is dialed up to eleven. I've been playing Valheim as well and even though it's a single player game, it kinda has that feeling old MMORPGs have, you feel like an insignificant person inside a vast world, everything happens slowly, you need to respect your enemies and grind your way to success. Another sad part is that MMORPGs aren't really social anymore, I didn't talk to a single person, didn't form any party, I joined a dungeon but got grouped automatically with other people
I'm gonna continue playing for a while, but AION 2 feels much more forgettable than when I played AION 1 many years ago

Primary goal: Determine compression efficiency between image codecs using a CVVDP score.
Secondary goal: Investigate diminishing returns between Webp and JXL
Currently only works with this specific input file: in.png. Only tested in Ubuntu WSL.
Replace /mnt/c/Users/1337/AppData/Local/Programs/Python/Python313/Scripts/cvvdp.exe with your CVVDP location.
CVVDP SDR display model used: standard_fhd. Scores tested: ~9.0 and ~9.5
My subjective CVVDP interpretation is that ~9.0 = medium quality and ~9.5 = high quality
Use CVVDP with photographic images only as it does poorly with Anime ones.

Workflow:
- Take 1080p anime screenshot in PNG.
- Crop it to 1:1 1080x1080 res (so it looks good on mobile and desktop)
- Resize it to 50% and feed it to the Resrgan upscaler using the Anime-HQ-W4xEX model (found on the waifu2x extension gui on github)
- Resize it to 50% again (ie back to 1080x1080), overall this significantly removes video compression artefacts and sharpens up blurry details.
- Convert to webp using these parameters in cwebp: -sharp_yuv -m 6 -pass 10 -psnr 45

/meta/Supporter Tier is Free Right Now! Just make an account and ask for it!
Check it out: Supporter Tier
I decided to make this thread so we can have a discussion about how Umi Galaxy is supported.
The idea behind the Supporter Tier is that, if the website grows, at some point we'll need to make some money to cover the server costs. And if it gets really huge, there will be even more costs beyond just the servers.
Right now, the servers are cheap and more than enough for the current traffic, so I'm taking this opportunity to give the Supporter Tier for free to people who register an account.
What do you think the Supporter Tier should have?
Right now, the Supporter Tier provides boosts for Clan and Alliance threads. Since everyone can create a Clan or Alliance, there needs to be something to prevent usage from getting out of control. We can't have an infinite number of threads with millions of media files without eventually paying for all that storage.
At the moment, Clan and Alliance threads have very little usage, so I was thinking about extending the Supporter Tier perks to regular threads on the normal imageboard as well.
What do you think? What kind of perks would you like to see in the Supporter Tier?

/meta/I've decided to make this thread to discuss what I've learned while trying to promote Umi Galaxy.
So far, I've noticed that visibility and clicks are important, but there's also a need to reach the right audience.
For example, yesterday I made a post on Reddit promoting the website on /r/webdev. The post got around 92k views and 200 likes, which translated into 200+ visitors to the website.
That looks pretty good, but none of those visitors actually engaged with the website in a meaningful way. Nobody posted on the imageboard, and nobody created an account.
/general/About 10 years ago I became interested in learning Japanese. Mostly because of anime, I just wanted to know what the basic konoyarou/tasukete/urusai stuff meant so I could focus better on the show's plot.
The tsukkomi/boke comedy in anime involving unecessary physical/emotional violence never fails to amuse me. I don't watch much anime these days but I have become interested in Japanese culture.
The Miko shrine maidens, Shinto shrines themselves, Geisha, tea ceremonies, Onsen, no tipping in restaurants, general lack of DEI, and so on and so on. All things that I wish the US would adopt.
Thus I've been on a journey, for a few years now, to pass the JLPT N5. I've bought many books on this but it's always turned into a 5 minute study session followed by 30 minutes of youtube.
Result: I can read common kanji compounds like 野菜、電話、入口, without furigana now and from memrise practice I know pretty much all hiragana/katakana. However I just can't power through the grammar parts.
SO I've signed up here: https://www.tokiniandy.com/
It's $10 a month and my hope is that this course dumbs it down enough for me to stick to it for longer than 5 mintues a day. I know some N5 stuff now so I hope it can boost me to N4 level this year alone.
I don't mean to shill this course and I have no idea if it will even be worth it. However my plan is to post updates here every week or so and let you all know how it's going.
I hope that this will help other anons here struggling with learning Japanese. It's an amusing/mysterious high-context language (see honne/tatemae) but it will break you especially with grammar.
Still, the challenge can be quite fun. Which is why I refuse to drop it. Gonna start tomorrow (today?) night so stay tuned.
/general/I've noticed that I'm always putting much more effort into my relationships with people than they put with me.

/meta/During a conversation with @webpgoy we cooked up an idea for an image tab in the settings. Right now all the static image options from our image processor sharp are available for testing.
I already noticed setting the effort to 6 increases the processing time by a ridiculous amount so maybe that should be capped to a lower value.
The idea right now is to test what makes sense, right now when you create a new preset it uses the default values so we can even double check if the default values make sense, for example a 800kb jpg is turning into a 1.5mb webp, which seems counterintuitive.
ps: animated webps and gifs are left alone, these settings don't apply to them

/technology/I took the 73 Mbps 4K NLUUG Tears of Steel encode, scaled it to 720p, and used CRF 10 veryslow x264 to simulate 720p BD.
SSIM cheating was disabled in AV1 with tune 0 and variance boost, 720p was chosen to handicap AV1's 128x128 superblocks.
Even when nearly maxing out x264 compression , preset 4 AV1 = ~30% better compression and encodes ~40% faster as well.
I confidently declare that H.264 is now official boomer trash like flickering CRT displays.ffmpeg -i tearsofsteel_4k.mov ^ -vf "scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2:black" ^ -c:v libx264 -preset veryslow -crf 10 -pix_fmt yuv420p input.mp4base_av1=ffmpeg -i input.mp4 -c:v libsvtav1 -crf 28 -preset 4 -pix_fmt yuv420p10le -svtav1-params psy_av1=keyint=5s:lookahead=120:tune=0:enable-variance-boost=1:variance-boost-strength=3:variance-octile=4frame=17616 fps= 18 Lsize= 212825KiB bitrate=2375.4kbits/s speed=0.73x elapsed=0:16:45.14base_h264=ffmpeg -i input.mp4 -c:v libx264 -crf 18 -preset veryslow -pix_fmt yuv420phttps://ftp.nluug.nl/pub/graphics/blender/demo/movies/ToS/tearsofsteel_4k.movframe=17616 fps= 13 Lsize= 304524KiB bitrate=3399.0kbits/s speed=0.535x elapsed=0:22:51.14

I noticed this place supports AV1, hope it's cool if I crosspost from 4chan's /g/ board. I present you a script that targets SSIM, only 1 input video file per folder though.1 problem: AV1 cheats in SSIM. It intelligently preserves the structure of video but destroys fine detail. However these disable SSIM cheating:@echo off & mkdir temp :loop set /p crf="CRF? (30-50 reccomended): " for %%f in (*.mkv, *.mp4, *.mov) do ( ffmpeg -i "%%f" -c:v libsvtav1 ^ -crf %crf% -preset 4 -pix_fmt yuv420p10le -svtav1-params ^ keyint=2s:lookahead=120:tune=0:enable-variance-boost=1:variance-boost-strength=3:variance-octile=4 ^ -c:a libopus -b:a 64k -y "%%f_CRF-%crf%_AV1.webm" echo: & echo SSIM result: ffmpeg -hide_banner -loglevel error -i "%%f" -c:v libx264 -pix_fmt yuv420p10le ^ -preset ultrafast -crf 0 -y temp/temp_source_2_10b.mkv ffmpeg -hide_banner -i "%%f_CRF-%crf%_AV1.webm" -i temp/temp_source_2_10b.mkv ^ -lavfi ssim -f null - 2>&1 | findstr "[Parsed_ssim" echo: ) goto looptune=0Prioritizes perceptual/visual qualityenable-variance-boost=1allocates more bits to low-contrast areas (such as skin, clouds, or foggy scenes) that typically suffer from blurring and artifacting in fixed-quantization encoding.variance-boost-strength=3Applies medium strength variance boost, enough to improve quality but not bloat bitrate.variance-octile=4Applies medium strength for the new 8x8 variance algorithm, which is used for adaptive quantization.
All of these not only give you better/accurate SSIM scores but allow AV1 to create subjectively medium to high quality AV1 encodes, not just compete in objective metric pissing contests.
