I don't really like higher math, but simple algebraic geometry like this is fun.

Did you know there's a whole field of higher math called algebraic geometry?


No please...

Is there a way to manipulate what thumbnail a webm/mp4 shows?
4 posts and 3 image replies omitted. Click reply to view.


I think frame 0 would probably be for the best, sometimes a webm is spoiled by showing its mid contents first.


The main issue with using frame zero is that a lot of videos with a fade-in at the beginning wind up with solid black thumbnails.


Frame 10?


Or, frame 10 if longer than 10 frames and halfway through if not?


Something like that might work well. I don't know any statistics on how long these fade-ins last so you'd have to test it on videos people have posted.

This seems to have a lot of examples, you could use them for testing:

I highly recommend using cloudflare's csam scanning tool to stop illegal images from appearing on your site. It also helps to block proxies as well. I think as an imageboard community we can stop this shit but we need to start taking measures to put an end to it. If you want to step away from your board for awhile don't leave posting open. It will get spammed. Just put it in read only until you come back.

And yes, I'm posting this on all the imageboards I find. No I'm not a bot.

cloudflare already has a stranglehold over enough of the net don't you think?


They offer a useful service.

I'll apologize if I offended. I can't really handle watching people troll others right now without over reacting.

I'm not really in the right place mentally to really explain much, but I went to elementary school in a foreign country which was undergoing a civil war. Moved around a lot and never really managed to fit into whichever country I was in. I'm extremely aggressive and discriminatory when it comes to situations of aggressor against bystander.
If I see someone doing something I perceive as bullying another person I'll opt for the max punishments.

I don't have an intention to change how I am or the system. I know that some people take extended breaks from the site(this is normal). During the russian-invasion some people are probably taking a break from the internet altogether while others are glued to it.

There are likely ways to improve the way things are run, which is what I like to gather when I do something unpopular.


Can the soyjak spammers be indicated with something more descriptive than "low quality" in the ban list? It makes it look like you get a permaban for "lol u tk him 2 da bar|?"


They should be labeled as spam. I can bring this up with the others.

get an extension cord and put your computer on one of those desks with wheels and wheel yourself outside.


I get where you're coming from, but I often post to kissu at work, and making the site more mobile hostile would make that a pain.

Has anyone actually ever failed a captchouli because they didn't know the character?
3 posts omitted. Click reply to view.


same as anon above, but sometimes it can get difficult with the images they choose.


The goal isn't for it to be difficult but I think it's clear.
Captchouli is a speed limit on spam rather than a deterance. The Kissu-UI being a fully JavaScript UI negates essentially all primitive web bots to our top ranked pages on search engines and linked from other sites.


Yeah. I think the ones I mess up most often are probably the blep :P or pout ones.


Sorry I'm such a newfag, but where is captchhouli used?
I found the github repo(https://github.com/bakape/captchouli), really cool concept, but there's no captcha on kissu, so is there some other website related to kissu that uses it?


I've modified the filter system (Flood Detected) to use a captcha instead of outright rejecting the post. Users fill out the captchouli captcha and it bypasses the flood warning. But the parameters only get adjusted by me if the site is in a situation where it's required. Otherwise you probably won't notice unless doing imagedumps(in which case I have a purchased-pass system that allows you to bypass it that have been given to ~10-12 people).

The captcha itself hasn't been adjusted in probably a year, but I can decide what sort of tags to use and pollute the database with junk that will never be used to make it harder to solve. However, it's such a rare thing because we try to only let mature people post and have automatic systems to block tor and some proxy/vpn.

What's the point of having so many boards for a dead site
21 posts and 3 image replies omitted. Click reply to view.


i only do it on occasion
cause i forget


It's an unpopular opinion here but I think less boards is better too


File:finger.png (347.71 KB,600x387)

Something to keep in mind about early kissu post stats is that during that time I was making like 100-150 posts/day, and after a while it became pretty tough to keep up and the numbers of replies to my posts was dwindling. Whenever I looked at the front page it was like looking at nearly all me, and it was grating on me. Now I make like a dozen posts and kissu is mostly autonomous, so I'd say the current time is much better. Also that state of affairs led to a bunch of bad meta threads that artificially increased the post rates.


I agree that less boards is better for a small site, but I don't see how Kissu is at all an example of having an excessive number of boards. There's three general discussion boards, a meta board, the Higurashi board, an image sharing board, a flash board, a polling board, and whatever hidden boards there are. The only board that I find truly extraneous is /cry/, and you could probably cut one of the general boards too, but otherwise there's not much that could be removed without reducing functionality. It's only when you've got a long list of utterly dead boards that it's really an issue, and I don't see that here.


>Also that state of affairs led to a bunch of bad meta threads that artificially increased the post rates.
This period will be forever known as "The Era of the Great Meta Debates". I am rather glad that era has subsided.

Hey that's more than I thought.







I lost the SQL to do it. Ask me again if you want me to remake it so it gives a full site count.

mysql> select count(*) from posts_qa where wl_token="
| count(*) |
|      270 |
1 row in set (0.01 sec)

mysql> select count(*) from posts_jp where wl_token="
Post too long. Click here to view the full text.


you can do the query using php like this:

function calcToken($wl_token){
$boards = listBoards();
$query = 'SELECT SUM(`top`) FROM (';
       foreach ($boards as &$_board) {
         $query .= sprintf("SELECT COUNT(ip) AS `top` FROM ``posts_%s`` WHERE `wl_token` = '%s' UNION ALL ", $_board['uri'], $wl_token);
       $query = preg_replace('/UNION ALL $/', ') AS `posts_all`', $query);
       $query = query($query) or error(db_error());
       return (int)$total = number_format($query->fetchColumn());
