Last issue established problems with Kissu's software and the need to expand into custom written user interfaces, moderation tools and customization of existing aspects.

As of this point kissu's experimental UI is in a beta state(all functionality planned out for the current revision, usable, but buggy and unstable).
https://beta.kissu.moe/
The experimental UI's purpose is to bring a 4chanX like environment into kissu providing it with dynamic content that reacts to the user's needs and offers a more responsiveness to the board changes(notifications on site content and your own). A list of features will be set below in the next post.
What we have now is a server with read only permissions on the vichan database to create it's own API pages for the React front-end+server.
While it handles poorly on 800 post threads, this is likely due to poor optimization that I'll fix in the coming weeks. That being said, there is a huge improvement to viewing experience in music threads such as https://beta.kissu.moe/qa/thread/47339#qa-47339

Kissu was also targeted for the first time by script spammers with preexisting knowledge on the workings of Vichan, even going so far as to script spam my banner program with account generation. Though we managed not to cause any interruptions to people's activities on Kissu it required a lot of energy from the staff and required me to get a moderator in addition to Cool. This giving us 22 hour surveillance over the actions happening on the site.
I also felt that time was up for /megu/ which I was uncomfortable about. The new board /ec/ offers a more arguably cultured/artistic board devoted to cute and sexy image sharing.
In the future we will need more moderation tools and I think that the following 3 will put kissu into a state where it's in full control of it's own agenda.

The current three tools that I feel will help kissu and not be too hard to implement are:
- Perceptual hashing: http://blockhash.io/
This will target people's avatars and repetitive image spam. Cloudflare already provides this for child sexual abuse material(and even forwards offending IPs), but for our own purposes this is needed to put more stress on spammers obfuscating their images. In the very least, when combined with a captcha, their spam becomes less recognizable and more comedic when they have to put noise into it. Nonetheless, I think that it's worth pointing out that no captcha or spam gaurd is unsolvable and there needs to be other solutions.
- Archive Backups
The archive on kissu doesn't yet function as a backup because post information gets wiped when it gets knocked off of the pages. Though the archive isn't planned to be a feature of the experimental UI, it is still useful for moderation and restoration of the site after captcha breaking spam attacks.

Still, what if the spammer is completely automated, breaking the captcha, flooding every second, spamming every single thread on the site… then what?

A year ago I made the proxy scrapper program that searches pages for IPs and submits them into the ban table.
This is a solution that catches 1 or 2 ips every so often. But what if it needs to be expanded to eliminate large swaths of IPs and thuroughly deny access from any webserver proxy? Well, it might be worth considering how 4chan handles rangebans. A new function should be added to vichan whenever the system or mod bans an IP address that potentially eliminates subnets when a certain threshold of bans are hit. If the IP scrapper sees that a number of IPs are banned between 192.168.1.0-192.168.1.223 it will make the decision that the 192.168.1.0/24 subnet is unusable due to spam and automaticly issue a ban. Naturally this will cascade upwards to 192.168.0.0/16 when a certain threshold is hit. This combined with filter rules for autobanning will create a system where script spammers are getting consistently shut out and maintain the speed of vichan which starts slowing down when the ban table hits 1000 entries.
In addition to this, it means that mods don't have to put in as much thought into combatting spam making it easier for these active users to contribute to the community and not police it.

-Real backups
Kissu needs an automated backup system. This is not complicated to do for the database, but images will take more effort. I could pay the server provider some money for this, but unless there is a crash, I'll find a manual system, or accept recommendations on this.

These will be done using Vichan since there will be way too much unnecessary wheel reinventing otherwise

For https://beta.kissu.moe/ I've forgotten to add the API information necessary to trigger inline expansion. It's in a really unstable state right now as well and my priority may be kissu's security for a bit, but I will list the set of features.

General:
- The experimental user interface allows for no javascript viewing of content such as polls, scores and posts. Posting is not currently in the plan, but could be in the future.
- A sidebar now contains most of the important navigational tools and page information
- Banners rotate when clicked, but banner ads work as normal.
- News, boards and partners are included into one object that is dragable
- Summary tab keeps track of all new posts on the site. It also can notify you whenever a post has been made on the site.
- Global and board search allows you to easily find what you're looking for
- Makes use of FireFox's right click menu and additional tabs in chrome
- It's a single page environment, meaning it looks like you're navigating the site but are always on the same page. This is theoretically faster and means that unless you are doing an application layer DDoS I don't have to worry about you clogging things up.
- XSS proof. There is only one instance where html may be inserted dangerously meaning user security is easier to handle.
- Some information is generated based on cookies meaning there is a possibility for a very effective no-javascript experience if demand exists.

Options:
- You can decide what boards you want to see
- You can create your own custom quote characters
- Mascots still exist
- Custom CSS still exists(and you can create your own shareable custom comment tags)

Home:
- Active threads shows you which threads have been last responded to
- Featured threads are admin curated best picks going on in kissu
- Hovering over will generate the full thread, and right clicking allows you to pin
- Partners are given their own dedicated space in recognition of their efforts.

Overboard:
- The overboard allows you to eliminate any board you want
- Allows for paged or catalog viewing
- Works fully with no javascript users.
- The overboard is sortable
- The index watcher will now behave like boards and ignore sage.

Threads in general:
- Threads and posts can be completely removed so you don't have to worry about even seeing the stub.
- Threads are also sortable(creation date, bump order, last reply, reply count)
- Threads (will) expand inline
- Index watcher still exists to notify you of new posts

Fileboard:
- The fileboard continues to exist now with the new file expansion method

Pollboards:
- This is the more disapointing aspect. Currently there's no way for me to effectively render graphs without making the script huge and slow. The text is just colored, which leads to some strange situations.
- However, it now works with no javascript, but you can't yet vote.

Posts:
- Posts can be expanded inline meaning text walls do not dominate threads
- Custom insertion of style tags. Typing [s test]text[/s] will give your text a span with the class of test. This means you can use custom CSS to a greater degree. For security, no transparency is allowed and urls, if not already, will override.
- Yen text and custom quote
- Replies to your posts will notify you when you have a response

Cites:
- Clicking a cite will now open up a new window that creates a reply chain. This should make it possible to reply to large threads and at a glance tell what the discussion is like.
- Citation hover brings up a preview like always

Files, Embeds, and Flashes:
- Images and gifs expand like always
- Videos(mp4 and webm), audio and flashes open up in a new window that allows you to browse the thread and close them at any time.
- Embeds are given their own window that allows for a larger view than previously.
- Embedded videos are also given thumbnails making it much easier to load pages such as the music thread.
- Hover over a filename to reveal it all

Submitting Posts:
- The reply or create box will follow you around unless you dismiss it(no longer have to worry about pressing back accidentally)
- The comment is under the WhatYouSeeIsWhatYouGet principle, or rich text. If you type in a quote the line of text will turn green. If you type [s custom]text[/s] then the text will be given your custom tag
- Post Previews allow for previewing how a post will look before it is submitted
- URL and Media submissions are combined into one element
- You can modify the filenames of your images by editing them in the given box
- Post submission on the overboard is multi-staged meaning you write up a post, then choose the board then if it's a poll you write up the poll.
- Replies to threads allow for a post queue to be created

 No.4245

This sounds cool but you might want to add a prefix to the class names, or otherwise people could use class names for markup that clash with the class names used elsewhere, causing Kissu's scripts and/or userscripts to malfunction and maybe even causing malicious things to happen if they're clever enough.

oh, heres one ive been wanting to mention but always forget. My laptop screen is small so if i ever have to solve a captchouli, the textbox to paste the code in as well as the submit button are hidden and i cant scroll down to it so i cant submit the code. ill take a picture of it next time it happens so i can show you

basically this pops up and the bottom part is hidden, if i scroll down it moves with the window as the rest of the page scrolls. changing browser size doesnt fix it either

A bit different and more along the idea of trying to create microthreads. Instead of making the user manually open every link what I've been working on is the ability to create a chain that automatically does it for you.

This UI is an interpretation of 4chanX's customization and automation features.

 No.4275

First new anti-spam tool is last one I'd ever want to use.

Effectively blocks poster's IP ranges from posting until they submit a ban appeal.
This would probably be used if captcha got broken and someone was using a residential botnet,
or if I died and cool needed to keep the site running.

My preffered system will probably be an ISP check on post submit that locks someone using a webserver ISP, or whatever regex term is needed.

 No.4276

seems like you have to pay money to get this information in a timely manner(ie. not querying someone's website).

ISP detection would have to be done after the post. In this case it seems like a better thing to do after bans on top of an automatic subnet lockout to get better information about weather the IP is from a commercial service or residential area…

 No.4277

decided to make a filter using PHP's gethostbyaddr. It's a hit or miss solution to detecting if an IP is a proxy or not, but it seems to work in certain cases.

I believe it functions on a lookup table, so there might be ways to improve this

 No.4278

I also added a whitelist table which will allow given users to get through filters and rangebans on approval.

My final system of auto-bans is going to be the bans table condenser which will estimate if a range should be locked down or not.
This will be an extension on top of the GoLang API server(Hazuki) to handle scheduled tasks of automatically adding via proxy lists and optimizing the bans table.

Hey, Vern, can you add in the ability to edit banners after you've posted them? There's been a few times where I've either wanted to update a banner or change the URL but been unable to do so without taking down the previous banner and uploading what's essentially a "new" one.

 No.4296

Archive restore is done, but it's half programmed on hazuki-golang and half on vichan(DB on api server, thread files on vichan) so I'll finish that off then move on to the perceptual hashing question.

After this, i'll leave mod tools until there's another need to improve them, but I think we have just about as much features as 4chan with the exception of better dashboards and management monitoring tools…

>>4295
I'll see what it take when working on it comes up again, but it shouldn't be anything more than another option in the user dashboard

 No.4305

there's a function which checks if bans have expired and it seems to be doing that very inefficiently.

If I comment it out kissu can handle 160,000 bans easily, but with it on it struggles to post in under 10 seconds

 No.4306

oh man… it's Twig isn't it… the thing I'm trying to replace is attempting to build the entire bans table https://kissu.moe/bans-all.html
so it freezes posting because it tries to create a json representation of the data. I can't put it onto another thread because php is single threaded… that's messed up

 No.4307

Archive functionality is developed on hazuki-go to serve as a temporary backup. What's remaining on vichan is the index construction and the archive.json generation.
Archive pages are depreciated, but information about them will stay around(json files, html pages and archive as a temporary image storage). They're not worth the continued investment in for functions other than moderation.

The proxy-logger is still making rangeban guesses on the 160,000 bans, but I realized by formula for /17 subnets was too large meaning none will be done as yet… when it's finished and I've moved over the archive stuff I'll run it again to do further compression if any may exist.
The logger can do /9 subnets but this may be overkill, I've yet to see.
This experiment is mostly about seeing if there's a way to confirm posting from risky locations rather than locking out. Kissu's whitelist-anti-ban feature will help here.

When this is moved over all that's left for the anti-spam purposes will be a perceptual hashing solution. Likely this too will be done on Hazuki-Go which will communicate with http://blockhash.io/ or a similar functioning package within golang.
What will follow is more work on the revised UI, see about some banner program alterations(editting banners, perceptual hashing duplicate checks might be good), could even do it as a warmup, make Hazuki-Go less hardcoded and I need to start thinking about money so I'll probably be making a bigger deal of that again.

 No.4308

zzz there's a problem where if it sometimes writes the json files incorrectly and it means I need to manually fix them. So naturally the property pages for home, all and so on have broken.

you can put that into a json linter to see what I mean. It might probably be a race condition where it writes chunks without locking first.

on the archive issue, there's very little percieved support for doing anything other than basic upkeep on it. Creating a light version of it would be done(along with better no-javascript support) if vichan's HTML generation were to be fully discarded.

Range optimizer and estimator took ~160,000 down to 139,220 bans. Currently /17 isn't in the list, but that wouldn't knock out too many more. There are currently 1163 /25 bans

This operation likely took a total of 20 hours where the ban insertion is a combination of string comparison and golang's CIDR creation from string and associated net.Contains method with an IP and range,

The ban insertion methods are n * m time complexity comparing all bans against inserted bans whereas the optimization method is n * 6n time complexity where it takes a given ban, creates /9 /17 and /25(6 times) variations on it and checks it against all bans for whichever is contained within it. The comparison method also is built to take a string parameter and convert it into an IP every time, this can be improved.

This process of 160,000 * 160,000 causes it to take the time it did(~20hr) and likely there need to be an adjustment to the search method and the comparison algorithm. A binary search would make the complexity roughly n log n, by comparison 160,000 * 5.2, however visualizing this for a []byte is a bit more complicated and I want to get back to fixing the UI.

 No.4315

Just the act of sorting might be the fix and tell it to stop when items are no longer contained within the optimization range… In which case the O(n*n) complexity is inevitable, but a bit better. A binary search seems like the best choice here but I'd rather not go there for now unless necessary

 No.4316

These adjustments made it so that the entire process of adding 160k items and compressing them took an hour so with that done, kissu now has archive restore and a good system of removing IPs that are regularly reported to spam/public listings. If there are any mistakes then you can appeal them.

 No.4317

speaking of appeals and stuff I ought to program a moderator input bayesian spam filter because the current weakest link of the system where ips are whitelisted is the appeals form….
It's an old method, but I know how to do it easily… There may be more accurate modern alternatives that don't rely on neural networks.

captcha skips are an interesting idea.

Something I could consider is IP hierarchy. If an IP is deemed safe (a temporary entry in the whitelist?) it gets exempt from captchas. This means there would be another page for requesting captcha exemptions.

Concerns with this idea are mostly adminstration

 No.4356

>>4344
I considered this as well, but it's probably not the best idea. For one not everyone has a static IP so you'd have to keep whitelisting IPs and this may run into issues for people that use VPNs or IPs without captcha that are no longer in use by the people who you meant to whitelist. If somebody with malicious intent were to stumble on one of them it could be very bad. Also, thinking in long term it may become a bit unsustainable with people maybe wondering why others are deemed worthy of this "kissu pass" of sorts and they aren't, and the more the userbase grows the more headaches such a system would cause. For my idea I think it'd probably incentivize using the features on /ec/ a bit more and maybe encourage people to post more if they don't need to solve a bunch of captchas each time they esnt to dump.

 No.4358

>>4356
hm, I guess it could be that this is a form of IP verification. However, all I need is a phone and I have a free pass anyways. It's much more flimsy because I don't have mod tools built around fixing scores or polls, they exist solely for the sake of entertainment rather than accuracy.

I can't really trust anonymous peer reviews to give out exemptions. I think it has to go through a bureaucracy just as a ban would, with clear cut rules that a paper-pusher could follow…

 No.4359

>>4358
You could make the exemptions reply-specific, so people can't use them to avoid thread-making captchas

limits to what can be done is a good idea regardless of what system gets used.

Captcha and rangebans are both exemptions that the 4chan pass gives and so far that's the ultimate system of security and freedom. But when you apply this into a 100% free model that I'm going for with kissu that idea falls apart and is too easy to abuse. It's tricky

Added perceptual hashing but currently no filter rules are set up. Blockhash works well, spammers will have to put in a lot of effort.

Banners is also having perceptual hashing set up. To stay consistent I need to finish off making test cases for this and do the documentation work for it.
Banners also has a similar anti-bruteforce setup for it.

Also made it easier for mods to see ban appeals so we'll have a faster response time to these kinds of issues and requests for whitelisting.

There's a big bug in vichan filters where if someone posts at the exact second as someone who violates a filter rule, they'll be effected by it.

 No.4428

it might be caused by something else.. it was a really strange situation.

Banners have a security update(account limits per IP, max login attempts per time cycle, blockhashing without hash distance). No new features to that as yet. Registration was previously closed but is open again.

Kissu has distance evaluated blockhash.
You can test out the no-distance blockhash by posting an image and trying to modify it slightly and posting it again. To test out distance evaluated you'd need to trip up a spam filter.

Last item is a simplistic email spam filter for the ban appeals in case it becomes such that someone tries to deny mods from picking out real appeals.
The value of proper appeals is because the proxy searcher and proxy range compressor are starting to catch legitimate VPN users. It might be of worth to also provide a key to donors that lets them auto-whitelisted from rangebans.

After this it's about bugfixing what's been done, from the UI that I haven't touched in a while to the bugs created from new mod tools.
It also goes without saying that since effort was put into vichan, kissu will likely always use vichan's post insertion and mod tools… items such as archive, deletion, polling, scoring and so on will likely eventually be moved over, but vichan's post filters and mod tools are great. I don't see a way around this.

I have to start concerning myself with money.

I stalled it out for a long time but I'm paying an affordable rent now and my savings are going to start getting chunked out every month. Is it possible to make a poverty level living on imageboards alone? It's time to put it to the test… I'm pretty certain getting a full-time job will mean quitting imageboards or making it a background project. I've got a commitment towards this site and community that goes beyond myself and want to continue as long as I can afford it. I want to focus on this site as long as possible and keep living a life of flexible hours and see Kissu gain in quality.

I'd like to give some sort of reward to donors and am thinking that it might be ideal to privately give out a whitelist key that exempts you from any vpn/proxy/tor/phone/agent bans and captchas. There are some ways I could do it without a sort of cash down deposit, but this is by far the most practical and my current donors are very generous and I want to give them something special.
This is the donation page should you be interested https://www.patreon.com/ECVerniy

Money is an important priority in this stage of my work here, but it's more important for me to finish off the last security feature and create the whitelist keygen. At this point Kissu is in a state of management, maintenance and bug fixes, where beta features are ironed out(new UI) and fixes/adjustments are made to Kissu's software. However, ultimately I'd like to get away from the software and start focusing on the brand and I'm not too far from this point where I have a software and financial model I want to push. One that doesn't let me compromise my beliefs and stays true to the easy going atmosphere.

You won't have to deal with this kind of stuff right away, but in the next few weeks I'll start making a push. Until then, there are still bugs to solve and features to test.

What do you think of using koremutake instead of base64 for displaying secure tripcodes?
http://shorl.com/koremutake.php

A major drawback of tripcodes is that nobody remembers them. So to impersonate someone, it's often sufficient to get the first few characters right. Koremutake encodes data as pronounceable strings which are easier to remember, so instead of someone's tripcode looking like !!PiTTj6CgcA, it would look like !!pikevafujojigru. It would only make sense to do this for secure tripcodes because with normal tripcodes it's desired that they look the same on every site.

 No.4453

>>4452
hmm, it's an interesting idea and it would have to be done before anyone starts using them.

A system of base127 seems like it would be interesting, but could it just be done by appending a vowl to the end of each capital letter constantant

PiTTj6CgcA would become PiiTaTaJu6CagcA. It's a similar system kind of like how in navigation when they read out the codes they say Alpha Beta Charlie Foxtrot isntead of ABCF

 No.4454

correction: base128, so all it needs is bit shifts and lookups in the array.

Wouldn't that still produce unpronounceable tripcodes when there are a lot of lowercase consonants in the tripcode? Looks harder to remember too.

Are you doing these in PHP? The way that makes sense to me in PHP is a base64_decode which turns it into a 7 character binary string. Characters are converted into an array of 255bit numbers. Each one is shifted 1 bit. It's not accurate to your method so I'm wondering if you had a better way to do it.

07ANLLIBMQ(60bit) into Ó°
,²1 as D3 B0 0D 2C BD 01 31(63bit) and each 8bits gets shifted 1bit resulting in "FROVUDA - GUVYBA - HA"

It feels to be like when a tripcode gets past this length it starts being way too long for people to care about it. I did a quick birthday paradox check and it seems feasibly impossible for someone to pick the same one in a set of 128^7 so I might just run with this unless there's a reason to think otherwise

 No.4471

Is it worthwhile to have a disjarring difference between trip styles? I think it looks ugly to mix and match them…

 No.4472

>>4470
If you're worried about the length, you might want to consider the capitalization idea, where you use the 8th bit of each byte to decide whether the syllable is capitalized. You could also think about the last option in >>4461, which is a bit shorter than the Koremutake encoding with some loss to pronounceability due to long strings of vowels. That one is just (in Python) 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'[n//5] + 'aeiou'[n%5] for each byte n.

 No.4473

>>4472
After looking at some examples, I no longer think the capitalization idea is good:
https://pastebin.com/aCrTEpbb

If you're going to do 7 syllables, maybe just for aesthetic purposes it would be a good idea to move the last hyphen between the 5th and 6th syllables so you have SOHEHO - RITO - SEDRO instead of SOHEHO - RITOSE - DRO.

>>4471
I can't think of a reason to have insecure trips at all if they're not consistent with other sites.

 No.4474

Titlecase and lowercase seem like the best quick fix. It might be possible to maintain case consistency by adding 128 more pronunciations. I used the list on http://shorl.com/koremutake.php without any modifications.

> Insecure trip

I suppose so, there's no reason other than perhaps using a solver to get funny combinations. Keeping legacy makes two different styles in one application. I'm not sure if I want this sort of inconsistency.

for the consonant parts and
['a', 'e', 'i', 'o', 'u', 'y']
for the vowel parts would give 43*6 = 258 combinations while maintaining phonetic distinguishability. I'm a bit torn between "gw" and "sv"; neither are very common, with "sv" being the more common one, but I think "gw" rolls off the tongue a bit better.

The code I used is at
https://pastebin.com/7b6Qm9uU
if you want to tweak it.

Also, the code STI wrote years ago to generate "secure" tripcodes is pretty bad. There's very little point in using a semi-modern hashing algorithm if you're just going to use it to generate a salt for ancient DES crypt(). Wouldn't surprise me if someone could crack the "secure" tripcodes just by enumerating over all possible 12-bit salts. You should rip that garbage out and replace it with a proper key derivation function.

 No.4484

Another thing that might make it look nicer is adding consonants to the ends of the words. If you're doing two words, you could end one word with consonants[n>>4] and another with consonants[n&15] where n is one of the bytes in the binary string being encoded. consonants could be something like
['', 'b', 'c', 'd', 'f', 'g', 'h', 'k', 'l', 'm', 'n', 'r', 's', 't', 'x', 'z']
where I've excluded q, j, v, p, and w for being less common than other consonants at the end of words in the SSA baby names list, and the first item in the array is an empty string so that sometimes it ends in a vowel.

Came up with some more syllable list candidates:
https://pastebin.com/GTJ0NL5z

syl1 is the same as >>4483

syl2 also requires that the syllables be common in words in Moby Dick. This removes a lot of foreign-sounding syllables.
https://pastebin.com/03BtXPt1
Moby Dick from: https://www.gutenberg.org/files/15/15-0.txt

syl3 first enumerates over all consonant-vowel combinations except those starting with Q (Y considered a vowel). Then three-letter syllables are taken from the SSA baby names list. The result is slightly shorter syllables. I think it might look a bit better.

syl4 is like syl3 but with the Moby Dick filter applied, and with syllables starting with X also excluded from the two-letter combinations.

To make the matter worse the memory access is pseudo-random which makes it very difficult to cache the data into faster memory. With this we are left with two choices:

>1.Use the slow and large global memory and spend more time fetching the operands than processing them.

If you don't want to do the final consonant thing in >>4484 it might be good to add some syllables with consonants at the end. I generated a new list where I'm allowing some consonants at the end of syllables. Consonants allowed at the end of syllables are not allowed to precede another consonant at the beginning of a syllable to prevent two inputs from mapping to the same string. I've also dropped some of the frequent consonants from the two-letter syllables; it seems to improve the fraction of names that can be generated. Currently 34.3% of the female baby names on the SSA list (weighted by frequency) can be generated from combinations of these syllables and a smaller fraction of the male names. I'm probably going to fiddle with this more to see if I can improve coverage.

it's beggining to become more than anyone could ask for in a tripcode on an anonymous website, but I can simply modulo the number by vowels+1 and it won't take me any extra time.

did what you suggested in 4484

>>4498
Do you mean by the number of consonants? The idea of >>4484 was to take one of the bytes and instead of looking it up in the syllable table, compute n/16 and n%16 and use that to look up consonants to end the names with (with one option to let it end on a vowel). Wouldn't be much extra work. Switching to a syllable table with final consonants like >>4497 would work too, albeit producing slightly longer output (about 1 character longer).

A noteworthy consideration is that male names tend to end in consonants while female names tend to end in vowels. Thus >>4484 would be heavily biased toward male-like names whereas >>4497 would be biased toward female-like names. At least in theory.

Running some numbers:
probability of randomly generating real names from the SSA lists
where the numbers are probability (first word) * probability (second word) = probability (both words)

syl3 without >>4484
2.29804e-07 * 5.81503e-04 = 1.33631e-10 (female)
4.16767e-08 * 1.055e-04 = 4.396e-12 (male)

syl3 with >>4484 modification
4.15631e-05 * 4.15631e-05 = 1.72749e-09 (female)
1.03712e-05 * 1.03712e-05 = 1.07562e-10 (male)

final consonants included in the syllables >>4497
2.21422e-07 * 5.669e-04 = 1.255e-10 (female)
4.21423e-08 * 1.31249e-04 = 5.53113e-12 (male)

Hmm… by these numbers, they're all female biased in a way, and the main thing affecting the numbers is the word length.

Another interesting measure is what percentage of names can be generated if you're using a tripcode cracker.

If we want a whole word match, syl3 without >>4484 can get to fewer names because it requires the name end with a vowel.
Below, the percent of names reachable by syl3 for various numbers of syllables (out of all names of the given gender, weighted by name frequency):
1 syllable: 0.7% of female names, 0.7% of male names
2 syllables: 14.9% of female names, 4.8% of male names
3 syllables: 9.2% of female names, 1.2% of male names
4 syllables: 1.9% of female names, 0.0% of male names
5+ syllables: 0.0% of female names, 0.0% of male names
total (any number of syllables): 26.6% of female names, 6.8% of male names

If we want a partial match, syl3 without >>4484 should perform better than above because a lot of names ending in a consonant will be found as substrings even though the whole words end in a vowel. I haven't calculated those numbers yet, though.

Here are the same numbers for the alternatives:

syl3 with >>4484 modification
1 syllable: 1.4% of female names, 3.5% of male names
2 syllables: 22.4% of female names, 22.7% of male names
3 syllables: 11.3% of female names, 3.2% of male names
4 syllables: 1.9% of female names, 0.1% of male names
5+ syllables: 0.0% of female names, 0.0% of male names
total (any number of syllables): 37.0% of female names, 29.5% of male names

final consonants included in the syllables >>4497
1 syllable: 0.6% of female names, 1.0% of male names
2 syllables: 21.7% of female names, 12.2% of male names
3 syllables: 10.0% of female names, 2.3% of male names
4 syllables: 1.9% of female names, 0.1% of male names
5+ syllables: 0.0% of female names, 0.0% of male names
total (any number of syllables): 34.3% of female names, 15.6% of male names

 No.4504

>>4499
Why is it still 7 syllables?

 No.4505

>>4504
a mistake. >>4502 is 9

This is too much tripcode… these modifications make it much better than what anyone else uses. The combinations don't have to be masculine or feminine, they just have to look somewhat appealing and recognizable without the use of a solver

 No.4506

>>4502
>Swe
Is this still the list from >>4475? I thought you changed it to syl3.

 No.4507

>>4505
If you implemented >>4484 it should be 6 syllables not counting the final consonants. >>4484 is supposed to make the tripcodes shorter.

 No.4508

good catch, I mixed up the backup and upload

 No.4509

test

 No.4510

I'm happy with how they look now. It's achieved the goal of making tripcodes less like random characters and into sylables that are pronounceable and somewhat pleasing to the eye. There are other tasks to build on that getting stuck on a feature no one uses as yet would be kind of wasted time.

It's also had the sideeffect of increasing hash security for both tripcodes and mod logins

 No.4511

As it is now the final consonants are just making the tripcode longer but not carrying any additional information. What I was suggesting with the consonant idea is that you can drop one of the syllables and instead use that byte n to make the two consonants with n/16 and n%16.

 No.4512

Are you pushing these changes to Github? I know you don't want to waste any more time (and I probably shouldn't either), but if I could see what you've implemented I could just send you a patch or pull request with the fix.

 No.4513

>>4511
I see. Yeah that could be good.

>>4512
I'll make another push into a seperate repo because this version of kissu is practically pointless without the golang server. I just have to check there's nothing important in any of the files

 No.4514

yeah it looks a bit nicer

uploading the single file is faster
