What is a booru?
Other have already explained, but to simplify, a tag-based media archive. The original is Danbooru (cardboard), an anime-based one (including NSFW, so I haven't linked). They often tend to be fandom-based.
A high-quality safe-for-work example of a standard online booru is Find A Fox.
OP's tool is a local single-user booru instead, using Hydrus Network as an example. Personally, I like its UI, and while it has a developer-driven swiss-army knife design vibe, I still like it and have used a wide range of its many options. I haven't tried Blombooru and can't see many screenshot samples so I can't assume what specific issues OP has and how Blombooru solved them.
Agree on the hydrus UI. I love it and wish more things used a more classic style interface. It's slim, it works, and while it can admittedly be a little bit of a maze, it does practically anything you can imagine. And most importantly it's not a damn website pretending to be a UI like so many things these days. Blombooru looks like a white space nightmare imo. I will say that the tag extractions from AI metadata looks very nice though.
And thank you for the link to Find A Fox. I don't know how I never knew about this, but I very much needed it! 🦊
this is how it looks for anyone curious
Thanks for the screencap. It looks nice! Much more focused than Hydrus.
it's like an otaku software were people upload artwork and other stuff, in theory you could store any kind of image or videos, and it is tag based.
What's an otaku? Sorry friend, can't that be defined in English words? I am more familiar than japanese jqrgob.
By your words, is it a gallery? A kind of public gallery?
Otaku is the Japanese direct equivalent of "nerd" in English.
In English otaku is used to describe a nerd nerding over Asian stuff (anime, manga, games, whatever). Some gatekeep it for Japan-only stuff, while others use it for K-pop and K-drama as well.
In Japanese it's the opposite - they use "nerd" to decribe people nerding over American stuff.
Edit: both loaned versions are a bit more derogatory than their "native" version.
I learned something new!
Thank you
it's an image board based around fan art and art work, but it can host anything, it culturally hosts that content because of overlaps between japanese animation culture and that kind of software
Thanks you!
Just looked it up. Otaku (お宅) is essentially 宅, which means "house". It became an adjective which describes someone who seldomly leave the house, which relates to animation (anime). It probably means somewhere to host images or videos now.
The etymology is a bit different from that. Otaku does mean "your house" (important distinction: it's always the second person's house, not your own), but it's also used figuratively as a formal way to refer to your family or just you. There was a culture, at least in the 70s and 80s, for enthusiasts in non-mainstream fields of interests, whether that be ~~TV manga~~ anime, science-fiction, wargaming etc., to talk to each other in a weirdly formal way, so they kept calling each other "otaku".
Only thing I want to add is outside of Japan, otaku almost exclusively mean anime fan
You're uh... Way off. Good try though.
Putting aside specific etymology, what it means in common parlance is basically "nerd" with a heavy implication of "really into anime and manga."
Well, sir, it is of course way off because I was only saying what the word originally means. It means "house" and there is no argument about it. "Nerd" is developed later.
Otaku has essentially become a loan-word in English. It's somewhat derogatory and generally used to refer to people who are really into anime and manga.
looks pretty neat.. do you know how well it performs with large collections? i've heard before that hydrus absolutely crawls when the data increases past a certain amount.
My hydrus collection is 1.9TB with nearly 1m files. Can't say I've ever had any kind of slowdown. A search with 24.8k results takes about 5 seconds, and that's with the media stored on a HDD (though the database is on a SATA3 SSD). And run by an 8 year old AMD Ryzen 7 2700X. Plenty fast enough for me at least.
that seems pretty good overall. thanks for sharing!
ive imported around 2000 images, and it didn't take much, also take into account i only have 8gb of ram, so it did pretty well and pretty fast. first it crashed a few times but because i had a 300mb gif and it tried to read it and crashed. i have around 5000 images more but ill import them in batches because those are relatively organized in folders so it'll be easier to add tags as i go than dump everything and figure out what do to with them later. so far i dont notice any lag with my collection, during import it may take a bit more if your collection is larger tho but if you also have more ram... it also has Redis as an option for caching, i havent used it tho
Are you the author?
no, the author is mr blomblo, hence the name!
