I'm OOTL, what's this?

windows 11 supports rar file extraction. inbuilt feature

isn't there some kind of unrar licensing issue?

either way, the only people who use WinRAR are people who have never heard of 7-zip

the thing is, not only decompression (and there are open source alternatives for unrar which are allowed by the license), but also compression (which is basically not allowed without special licensing, because rar is a proprietary and closed format, only decompression is open and documented, maybe Microsoft paid for it) ```“We have added native support for additional archive formats, including tar, 7-zip, rar, gz and many others using the libarchive open-source project,” says Windows chief Panos Panay We also plan to provide support for creating those files in those formats in 2024 ```

oh you can `.tar.gz` something now, interesting

I used 7-zip for years but one day I got bored and decided to try winrar and compare it to 7-zip and I came to find out that I actually like winrar way better then 7-zip

so now I just use winrar and only pull out 7-zip for edge cases

may I ask what kind of aspects you prefer from winrar?

obligatory https://twitter.com/zacbowden/status/1643594814120656897

I love translations without context

it reminds me of when the cleveland plain dealer said that someone was Back In African-American

after a system find/replace from Black -> African-American

I generally think as a GUI program it's better designed and doesn't suffer from a lot of the problems of 7-zip such as: - Doesn't understand UAC at all leading to the program failing either silently or with a unknown error if you try to do something that requires admin such as changing certain settings or trying to do something with a protected folder. - Doesn't use the native Windows date time format when displaying time - Doesn't allow you to change what font it uses and just uses MS Shell Dlg. - Doesn't prompt you to setup file associations during install which I have seen lead to quite a few problems for end users over time (for example I had a friend that for the longest time didn't even know 7-zip had a GUI and they where using it as their main program to extract things). - Settings menu is lacking a lot of nice options. - Doesn't understand/make us of mouse 4 and mouse 5 buttons. - Just in general has a bunch of smaller issues that add up The person who made 7-zip really understands their stuff when it comes to compression algorithms but I think they are lacking a bit when it comes to program functionality and design.

this is why I just use 7-zip as a backup for edge cases nowadays

I also don't really recommend friends and others to use 7-zip anymore but if they insist on using it then I usually give them a small fork I made of it

sometimes ill ask people why they state that 7-zip is better then winrar and the only reason I have really ever heard is either "because it's open source and free" or "it just is"

being open source and free doesn't automatically make something better but it is nice

> Doesn't prompt you to setup file associations during install which I have seen lead to quite a few problems for end users over time (for example I had a friend that for the longest time didn't even know 7-zip had a GUI and they where using it as their main program to extract things).

yes it does

and nagging you to buy it is a massive downside of software, fr

it's why I stopped using sublime text

nagware is annoying

not for me

it just installed with 0 options

well 1 option

are you reinstalling or installing for the first time

that may affect it

I use a fork of it which resides in a different folder

ill try testing in a VM maybe

it at least used to do that, I don't know if it still does

unrelated but interesting point about 7zFM is that the GUI is apparently relying on privimitive windows APIs, which is why it's backwards compatible all the way down to windows 2000

but as a side-effect of this it works in recovery mode

whereas windows explorer is not

7zip associates .7z files by default but will leave most other filetypes to their own programs

At least recalling back a year ago when I had to reinstall after a dead drive

something else I wanna point out is from what I have seen if you do not setup associations from the GUI in the settings menu then the files you associate it with will not have they custom icons and will just have the 7-zip logo.

I have seen a lot of computers where 7-zip associations where not done from 7-zip's GUI leading to the custom file type icons not being used

most computers with 7-zip I see are like that

In my case the 7zip GUI makes the files show as the logo

WinRar context menu also has a nice property of displaying only "compress" subset of selections for uncompressed files and "uncompress" for compressed, while 7-zip displays everything which can be confusing for beginner users

Yeah, 7zip is more intermediate-expert and winrar is from amateur. Got some nice features but takes time to learn them

I install 7zip daily on many computers. It doesn't even register .7z files during installation.

it used to do that then, iirc

unless I'm just misremembering

there are msi and exe installers, maybe they behave differently

perhaps

i used winrar 15 years ago

7zip may not have the best defaults but after setting up the context menu I can't go back

Both exe and msi have the same behaviour

winrar can all 🥱 do not update to 11

Linux can not reFS ⚰️

Windows cannot btrfs, zfs ⚰️

⚰️ ok ⚰️

https://github.com/maharmstone/btrfs no native support, but there is this

tbf, zfs is incompatible with the kernel licensing-wise

so it can't be shipped by default with linux distros

that's the kind of thing escher did a lot

not to be confused with Theodor Escherich, discoverer of E. coli (although he was not the one who named it after himself – he originally named it _Bacterium coli commune_; it was later renamed to _Bacillus coli_ in 1895 and then to _Escherichia coli_ after Escherich’s death)

btrfs, zfs, refs? nope, true king is coming 😄 https://bcachefs.org/

why would someone use it when btrfs exists? Is it better than btrfs?

I am asking it because I don't know anything bcachefs

Well, it should be. I dont think anyone would make new FS if they didnt think its better then the previous ones.

but i cant tell you exactly how, I am just excited to see what becomes of it

btw, I personaly use ZFS on my TrueNAS... its shame that stupid licencing problems keep it from kernel

from https://news.ycombinator.com/item?id=22005653

it's crazy that it's faster to develop completely new FS for linux kernel than to change licence of already developed one to be used in kernel (ZFS) 😄

"advanced new filesystem for Linux" to me is a downside I like ext4 cause it's on so many systems most of the bugs have been ironed out

ext4 is very good for what it does, but it's just different from CoW filesystems

end users generally have no need for CoW snapshots

they aren't backups

i guess you can simulate CoW like behavior like red hat does https://stratis-storage.github.io/

i am end user and I very much like snapshots on my TrueNAS

why? it is needed for rollbacks in case of updates failure.

it's not a backup though, if you have corruption, it corrupts the snapshot

because of the cow nature

what corruption? write corruption? thats why it check integrity

i even have ECC ram

Some updates cause bugs. not file system corruption

saying "my filesystem will never have corruption" is a delusion

oic what you mean, like you try to install something and it fails and you want to roll back to pre-install

but what do you mean by that? you mean that some bug occures and whole filesystem implodes?

whole filesystem? no

but parts of it

on opensuse tw, it creates snapshots during package installation and removal. it is an useful feature

like restore point in windows

i get what you mean... I use ZFS as target for my PC backups so if ransomware got on my PC and encrypted even backups I can just restore snapshot because they are read only

also it's easy to backup snapshots, fwiw

you are right, that I should ideally have second NAS and fully backup the first NAS to the second one... but I just do the best I can with with only one

I like that I can fuck up whatever and just use snapshot and revert it.... I like that snapshots dont use much space, they only store differences

in particular, snapshots give you a temporally consistent view of the fs at a certain point in time - you *don't* want to backup different parts of your fs at a different time, it's a great way to break stuff

It looks like kernel like linux-tkg comes with bcachefs

https://www.gizmochina.com/2023/06/04/huawei-challenges-eye-protection-benefits-pwm-dimming-1440hz-honor-responds/

> Honor believes that the impact of PWM dimming frequency on eye protection is influenced not only by the frequency itself but also by factors such as fluctuation depth and duty cycle. that becomes a very believable hypothesis as soon as you learn of this difference between the flickering of incandescent vs. LED lighting, and then realise (for example by looking at the measurements on notebookcheck) that displays vary in those aspects too

when they review a device, notebookcheck shows graphs for various brightness levels https://www.notebookcheck.net/Apple-iPhone-14-Pro-review-The-Apple-smartphone-is-ready-for-the-island.659550.0.html#:~:text=Measured%20at%20a%20fixed%20zoom%20level%20at%20various%20brightness%20settings

(I wish they’d make these a bit easier to read)

my 7th gen X1 Carbon had deep, slow PWM that caused a visible rainbow effect when moving my eyes, similar to single-chip DLP projectors

from what I understand, it was specific to the 4K model (the 1080p version was spared) of the 7th gen (which introduced the 4K option, and they fixed that issue for the following generation)

bad luck for me

ah, no, 8th gen still had it: https://www.notebookcheck.net/Lenovo-ThinkPad-X1-Carbon-2020-Business-Laptop-Review-4K-display-costs-battery-runtime.482570.0.html

> However, there is a massive drawback: At a brightness level of 99% or lower, we can detect PWM at a very low frequency of 200 Hz, which can definitely result in problems.

it looked like this in slow motion

it looks as though the red subpixels didn’t flicker?

My eyes gets irritated and tired whenever I use my oled phone in dark place unless I turn on flicker prevention setting.

I don’t think my eyes minded the X1 Carbon’s flickering, but my brain did, in that it was very distracting

They'll probably be fine, as the foss version of rar doesn't support encryption, which you often see in the wild.

I didn't expect opera with this much percentage.

I have a question for compression specialists, for some reason I can't find an answer to this question either in the RLE study material and even the chatgpt neural network can't answer it. The question sounds like this: I have a binary file that contains information, and all Byte variants are used to transmit information. The question is how Intermediate service data can be written, that the sequence has started, or what is the length of the RLE sequence, if all the byte value variations are already use in the most compressible file and cannot be used as pointers

yeah pretty cool stuff

all formats always have pointers -- that containers, that codecs, service information that is determined in advance. Even unicode has this in order to use more than 1 byte, but these are all pre-known values. I can't find the answer to the question - what do compression algorithms, archives, do in order to solve this problem. There is literally not a word about it in any educational material. And all the examples are done on numbers or Letters. At the same moment, the neural network says "just take one byte and write that it is the beginning of the RLE sequence" -- how can I do this if all the bytes are already used in the Compressed file? <@853026420792360980><@557099078337560596>

????

compression formats add headers and things like that

Examples?

https://www.rfc-editor.org/rfc/rfc1952.txt

it looks surprisingly small... wow 12 pages. need to read

that's just of the container, the compression spec is https://www.ietf.org/rfc/rfc1951.txt (still not very long)

not much either. In fact, I didn't even think about going to read the real documentation of archives, because I'm used to the fact that there are more than 200 pages

hm.

Amazing, that's something I wanted to be able to generate ten years ago (lol)

why does it exist? <:Thonk:805904896879493180> one of the most useless things

it's been almost 30 years, but it's literally not used for anything anywhere, I can't create a file with a different kind of compression or without compression at all

because in 1996 they wanted to futureproof it

it's three bits, who cares

but at the same time, the archive will break if I try to change the number 8 to any other, it's just amazing that 7zip does not skip checking this number at all lol

lost functional,

PNG does this as well, it has a compression method flag

in IHDR

but the only permitted value is the one indicating zlib

do png 2 now <:KekDog:805390049033191445>

~~lossless JXL~~

but no, it can be changed, there is a compression level of 0 that makes PNG analogous to BMP

that's zlib compression level isnt' the same thing as compression method

?

compression method in the PNG IHDR says what algorithm is used for compression

zlib compression level 0 still outputs zlib-compatible compressed data

it just doesn't actually do anything interesting to "compress" it

without compress

ye

it just sticks a header in front of it and that's about it

where is GZIP compression 0 ?

gzip is a container for DEFLATE it's not actually a compression algorithm

zlib - DEFLATE - GZIP

Where is the answer?

you'd have to look at DEFLATE compression 0

which is detailed in the DEFLATE RFC

<:Thonk:805904896879493180>

Well, in this case, we can say that the developers are complete idlers, they could not write a couple of lines of code that would encode all the data in blocks marked Not compressed, and make the compression mode 0

you can do that in ZIP

not in gzip tho

for some reason, the uncompressed compression mode was cut out of 7zip-zstd when the 7z archive is marked as "copy". This is why 7zip-zstd just doesn't have it, but it does in the original 7zip. Also, all levels 1 of 7zip-zstd are marked as "Store"-- What does that even mean?

as the whole point of gzip is to compress a single file

store means "don't compress"

zip and 7z both support different compression methods

gzip does not, as gzip's purpose is to compress a single file

no, if I need to compress without compression, I use the best archive that contains a whole normal file system in its head -- 7z

if you need to compress a *single file* without compression you just use the original file......

single file ok just use tar

or just

the original file

7z and zip are *archive* formats, which is why they support multiple methods

sometimes it is useful that no one knows what the file really is, for example, when sending .webp in telegram

<@226977230121598977> on a side note, this tool may be interesting to you: https://github.com/wader/fq It has some analysis for gzip and png, I didn't use it, so don't know how good is it, but maybe it can be handy for you

in fact, you are surprised when you find out that there are only 2 archives that can compress and contain more than 1 file, these are only zip and 7z

literally all

"Store" means no compression

I'd use some "escape sequence" - eg. define "ff xx" as a RLE times xx, where xx = 00 .. fe, and encode single "ff" byte as "ff ff"

that's one way to do it, yea

most recently, I was parsing mp3 through the documentation, in fact, I don't think I need this tool for anything

looks so geek

Aah, well, then it's clear, the author 7zip-zstd is dumb

literally

the 7zip-zstd project is already 7 years old, and are you serious about it?

Hmm, but you just came up with the idea. But I would like to know how it really is, now I will finish reading GZIP and start reading DEFLATE documentation

another real unreal useful flag

the most important information at the beginning takes only 3 bytes, but then there is a gathering of completely unnecessary garbage, at least 7 bytes of the GZIP format itself are spent on nothing

In fact, it was necessary to start with the documentation of the compression algorithm itself, there is literally nothing in the GZIP documentation, in general, except that it sets the type of compression algorithm - nothing in gzip format is done anymore.

That's it, I found out

in fact, it's even strange that I didn't realize this a little earlier, because I've already worked with huffman trees

The answer to my question will be this: Due to the Huffman tree algorithm, any amount of data with any content variants can be converted into bits of any length that will be unique during reading, moving exactly along the tree. Bits can be of any length, from 1 to any number - and the size of the tree can be any size.

this also means that the RLE algorithm cannot be used at all without Huffman

n.txt.gz 165 bytes n.7z zstd 260 bytes n.txt.zst 160 bytes

💁‍♂️

my self-written (with the help of a neural network) huffman algorithm compressed into 373 bytes. it is worth saying that lz77 works well

on such data sizes, Brotli is really the best compression algorithm for text, bypassing the other ppmd algorithm by 1-2%

What does he mean by sizes larger than ideal for the web? Is he spreading misinformation?

it depends on what you consider "ideal for the web"

Well, that depends if you count 'ideal for the web' as 'lowest size possible'

Maybe he thinks emojis and smudgy images are ideal for the web

Ironically, emoji's would probably compress better with JXL

For lossless jxl yeah what about lossy jxl vs avif?

who wants lossy emojis

yuck

but if the file is small enough avif loses due to its massive header

idk if they've fixed that

that is not a real problem

I think the avif team did benchmarks on lossy jxl vs avif to show how avif is better

for emojis?

just use fonts

Yeah

COLRv1 should allow emojis in fonts to be possible now (it was possible before but very limited)

They lose their minds whenever they try to justify avif's superiority.

tbh any (insert image format) advocate

including jxl

I count at least the following: - red herring + appeal to ridicule + ad hominem + guilt by association (once, one of you proposed this unrelated and obviously (to me) ridiculous hypothesis, so clearly everything your group says is doubtful) - motte and bailey (chrome’s support for jxl was behind a flag -> there was no support to remove, no invested effort, zero potential intent to make it the default) - poisoning the well (“Folks with a taste for spreading misinformation will twist this though 😀”) - shifting the burden of proof (wb presented contradicting data, so suddenly, Jake supporting his original claim is “Brandolini’s law”)

am I missing anything?

ahaha- I see you are a fellow maxim-enjoy.

SVG can seriously slow down the browser, especially animated ones. Bitmaps makes sense.

I wonder if progressive vector graphics are theoretically possible with tesselation. Icons don't need that much detail.

Didn't know animated SVG was possible, although with JXL splines you could probably do animated progressive similarly

is it possible without embedding javascript

recently: I'm now working for some NPU startup since last December and doing too many dirty works (*cough* Python C API *cough*)

I actually enjoy doing dirty works, as long as I have a reasonable confidence that I can do this, but it does take so much energy that my Github presence is greatly reduced (I use a separate GH account for work)

ah sorry, hardware accelerator for machine learning. there are several synonyms but NPU seems to be the best known terminology.

while GPGPU excels at parallel computing, ML computation payload (e.g. matrix multiplication) requires close cooperation between memory and computation unit which GPGPU can't fully do, so dedicated HW solution is useful

once again Google does have its own NPU, namely Tensor Processing Unit, but you can't directly buy TPU for various reasons, hence startups.

that said as I've mentioned before I do not design hardwares (I can't do), I'm mainly a plumber 😉

His MO is shilling for whatever Google does. I'd just ignore him

MO means?

> (I also recall you telling everyone that Google forced WebP on everyone by dropping support for JPEG on YouTube. The source of this was your imagination) As a response to Jon's legitimate benchmarks. When in reality Google *did* do this, kinda - allowing WebPs to be 30% smaller (not sure if there was an efficiency benefit here) & making Chrome WebP only. I think that's prob what he's referring to, but still, why bring up a totally different argument?

modus operandi

Ah.

Jake doesn't even work at Google anymore. I guess he somehow thinks that jxl is only useful at q > 90 and that jxl getting adoption will mean that everyone will start using high qualities, making the web slower. Or something like that.

Google did kind of push webp, not by making their own sites like YouTube break on other browsers though. They let other sites do that, and kind of encouraged that behavior by making their web perf tools and search rank metrics favor lossy webp over progressive jpeg, and not penalizing the use of webp without fallback in any way... Probably not intentionally or with some kind of evil plan, but the end result was that some websites started to serve webp without fallback, which basically forced firefox and safari to add support because whenever a page works on chrome but doesn't in your browser, that's not considered a bad page, it's considered a bug in your browser.

So I made an incorrect claim saying that YouTube did that — but that was an honest mistake: I did test YouTube in Chrome with "disable WebP image format" checked, and I saw that all video thumbnails stopped working, so I assumed YouTube didn't work on browser that don't support WebP (but it turns out it does, it just has some weird way of detecting webp support, maybe it only checks the UA string and not Accept headers or something)

but my main point does still stand imo. I said > Chrome can force things because they can control both the client and server side. E.g. with WebP, they first made it work in Chrome, then forced other browsers to also support it by making YouTube use it without fallback, effectively 'breaking the web' for Firefox and Safari. and while the "making YouTube use it without fallback" part was false, the rest of the sentence is imo still true: > Chrome can force things because they can control both the client and server side. E.g. with WebP, they first made it work in Chrome, then forced other browsers to also support it by ~~making YouTube use it without fallback, ~~ effectively 'breaking the web' for Firefox and Safari.

Victor Hugo said once : don't spend too much saliva justifying yourself on twitter

I did this more than once

after many online “discussions”, my strategy now involves checking that the other party’s points are actually relevant

otherwise, there is a risk of getting drawn into a different direction that has nothing to do with the point that you were originally trying to make

and potentially even feeling that you have to defend a position you don’t even hold

if a point they make is not relevant (like here, with “once, you said something based on wrong data”), I might briefly address it (“part of my data was wrong and I quickly retracted it”), but then I would try to recenter the discussion (“but back to the point, do you have data suggesting AVIF performs better?”)

(not trying to say that this is the best way to do it or anything)

(this is the polite version)

he's been awful quiet since jon asked for evidence

fun fact: for some reason ssimu2 really likes the following mpv upscaling options on my very small dataset: ``` profile=gpu-hq vo=gpu-next scale=lanczos scale-radius=2 scale-window=kaiser scale-wparam=1 ```

probably just a quirk but was the only combination that scored over 60 on a 2.4x upscale in this test

> Jake doesn't even work at Google anymore. I guess he somehow thinks that jxl is only useful at q > 90 so, the most useful qualities? 😄

I can see color difference on firefox, edge and chrome on windows 11. Does it mean these browsers are bad?

they depend on your system

are you color managed

I'm using Arch and the two pictures look identical to me

and Firefox

did you turn on iccv4 (off by default)

the website's srgb version is untagged so you would need mode 1

insufficient test anyway imo

mode 1 to color manage all

here have some greens

should be noticeably different on a monitor with wled backlight or newer

on windows 11 both firefox and chrome don't support windows advanced color api (for when auto color management is on), but at least firefox allows setting a display profile manually

is prophoto HDR?

it's wide(r) gamut

I ask cause I have an sRGB SDR monitor and they look the same

which means I don't have a "wled backlight" or whatever

basically any 2017 ips or newer

ah, I don't have an IPS

also I think my monitor is from 2015

so that's 0 for 2

I use it to test if color management is working

if you know your monitor is less than srgb then it matters less since you wont be seeing anything oversaturated.

it’s likely that the ProPhoto image still only encodes colors that are in sRGB, and that they are therefore supposed to look identical regardless of your monitor’s gamut

my favorite way to test if color management is working is the green bench

it looks green if the ICC is stripped

is it missing the ICC profile? it looks green even in Chrome

which I think discord is doing

https://0x0.st/Hcxm.jpg

ah, this one works

this one is a link

is that what you uploaded?

does it now strip on upload then?

same file I sent to discord

disappointing

so it looks like discord is stripping ICCs on upload

it didn’t use to, did it?

heres a tip you can prevent discord from messing with your PNGs and JPEGs by adding ".webp" at the end of their name

this is the green bench from the conformance repo, reconstructed as a JPEG (djxl bench_oriented_brg/input green-bench.jpg)

for PNG sometimes ICC gets stripped while other times it doesn't I think it depends on how the ICC profile is embedded (I think? I might be mistaking another program)

what do the people who program “let’s strip the ICC profile” think it does?

or do they just forget about it?

they probably think that the ICC profile is random unnecessary metadata cause they have sRGB monitors and all their images are sRGB, ig

strange.. how come my prophoto green wasnt stripped

on strike if I remember, to protest against the new policy which will put a paywall for third party apps using the API

the subreddits are striking, yes. but reddit itself is also currently down https://www.redditstatus.com/

lol, I wonder what happened — is reddit "striking back"? did some of their systems break by suddenly having many subreddits switch to private? did they get hacked?

Maybe the IT people at reddit are also striking against the new policy

Wouldn't be surprised if none of them use the official app 😂

Man, they even managed to make color complicated.

How could color not be complicated? It's all about the biology of our eyes, the physics of light, and the engineering of reproduction technology from inkjet printers to OLED displays.

if you missed it : https://www.youtube.com/watch?v=xAoljeRJ3lU is an entertaining video on the topic

Why utf-8 use this

Why not this 1xxxxxxx 1xxxxxxx 0xxxxxxx 1xxxxxxx 0xxxxxxx 0xxxxxxx

because removing 0xxxxxxx will yield a valid encoding in your scheme

UTF-8 was designed to be a drop-in replacement for C libraries, thus no nulls except for U+0000, and no valid UTF-8 sequence is a subsequence of other UTF-8 sequence (otherwise naive byte-based C libraries will be confused)

? 0xxxxxxx 0xxxxxxx 1xxxxxxx 0xxxxxxx 1xxxxxxx 1xxxxxxx

`0xxxxxxx` is a subsequence of `0xxxxxxx 1xxxxxxx`, isn't it

so if you search for the former bytewise, the latter may be mistaken for the former

Oh yea 0xxxxxxx 1xxxxxxx 0xxxxxxx 1xxxxxxx 1xxxxxxx 0xxxxxxx

Now all same

now the second is a subsequence of the third 😉

<@268284145820631040> same?

no, because of the first byte

Why first?

Read byte to 0xxxxxxx

I'm not sure what do you want to say, if you think UTF-8 has an overlapping sequence, give me an example

overlapping ?

as in, some sequence can be mistaken for other sequence

I can make a concrete example for your scheme

how

do

say a character A is encoded as `01010101`, B as `10101010 01010101`, C as `10101010 10101010 01010101`

now searching `B` from `C` will yield a false positive

Not, only 7 bit in byte

what?

Same as unicode

``` B is represented as 10101010 01010101 C is represented as 10101010 10101010 01010101 ```

Ansi is 7 bit

so a bytewise search routine will think `C` contains `B` at the offset 1

Why are you write first bit as symbols

sorry, updating

is this okay now

The other day I created my tokenizer based on a complete search of all the values of the text and the creation of a dictionary. So, to store 21 bits of information in the form of numbers, I use just such a storage system. Its works

well your search routine can be made to recognize and reject such false positives

that's fine, everyone did that for legacy character encodings

UTF-8 was designed so that byte-wise routine can work as is, which was a big improvement

But of course if you don't read the last byte then everything will break

but i use first in my system

UTF-8 can detect that though

(technical term: self-synchronizing code)

But here are my current results with the most common text tokenizer. mrsteyk/rupgt-chatml-tokenizer 274, 4674, 306, 309, 2789, 3057, 6957, 294, 296, 13124, 16, 492, 505, 19041, 2712, 309, 1209, 14938, 7150, 1209, 571, 2040, 4678, 16, 7155, 35250, 15559, 3136, 790, 435, 3417, 20755, 12538, 266 My -5935-18486-201-14619-4887-402-451-917-271-16-4960-5513-1346-12997-12482-3420-4302-25335-18191-13724-8737-278-16282-572-641-4187-982-6055-26049-27225-519-7151-20733-11137-1604-5697-271-88-252-397-384

My same

in my example, `C` but the first byte missing will look exactly like `B`

you can indeed detect the last byte missing, but not in the other direction

Each character always starts with "1" bit, so if something breaks, will one value

yeah, your design is indeed better than most legacy multibyte encodings, but worse than UTF-8 I meant

in general... In my memory, unicode looked like this 111xxxxx 11xxxxxx 1xxxxxxx But in fact it turned out to be some kind of ineffective bullshit, so I had to come up with my own

nope, UTF-8 is designed so that the first byte alone gives the total information about how subsequent bytes would look like

`0xxxxxxx` is a single byte. `110xxxxx` is two bytes long (i.e. one byte more to read). `1110xxxx` is three bytes long, etc.

and all "subsequent" bytes are `10xxxxxx`

If you lose one byte of 10xxxxxx everything will break. I don't see the point

you can argue about the exact byte allocation (for example, UTF-8 originally allowed up to 6 bytes, and nowadays 5--6 bytes are gone, leaving some bytes completely unused)

why?

let me give some concrete example

I have this sequence: ``` 11101100 10010101 10001000 11101011 10000101 10010101 ```

if I understand you correctly, removing the third byte `10001000` should break everything, right? is this what did you mean?

in my 1xxx1100 0x010101 0x001000 1xxx1011 0x000101 0x010101 x = now is free bit

sorry, my example is in UTF-8, not in your scheme

I made a translation from unicode into my scheme, saving the characters, all the information, and freeing up space

yeah you have free bits, but removing `0x001000` as I did will result in a *valid* sequence

which is by itself, fine

Yes

but this implies an overlapping subsequence issue which may be problematic in bytewise routines

Broke one symbol

yeah, one symbol only

Same in my

that's a definition of "self-synchronization"

yeah your code is also self-synchronizing

but not safe for bytewise routines

I don't doubt your code is better than most multibyte sequences

and can be useful for cases where you want self-synchronization but don't use bytewise routines ever

unfortunately bytewise routines are there, and they are thoroughly optimized (because they don't assume anything)

so if a coding scheme can work with bytewise routines, it will get optimal routines for free

I don't know what you mean. In my program it works like this If bit = 1, then see if the next bit is equal to 1 or 0, if 0, then see if the next bit is equal to 1 or 0, if 0, then create a number from these 3 bytes

yeah, "if bit = 1" condition should be a part of your algorithm

bytewise routines... say, C's `strstr`, don't know about your bits

they don't concern if a particular byte has an MSB set or not

For beauty, I work with real mathematics, converting a number into bits, then dividing it by 7 bits, and adding this control bit to the end of each byte

just real 0010101+"1"

and in my program like this xxxxxxx1 xxxxxxx0 xxxxxxx0 xxxxxxx1 xxxxxxx1 xxx...

and 7 14 21 bits saved

As I understand it, it is important for unicode to have a clear understanding of how many bytes the end of a character is

only matter when you implement Unicode-specific algorithms

a generic string search works same for byte sequences and UTF-8 sequences

that's true so long as the inputs are correct

UTF-8 needs to reserve 0xxxxxxx for ASCII compatibility.

ok. Not problem.

0xxxxxxx ansi cmptblty 0xxxxxxx 1xxxxxxx - new (14 bit of data) 0xxxxxxx 1xxxxxxx 1xxxxxxx - new2 (21 bir)

https://github.com/google/brotli/issues/591

I was really surprised to find no ready-made build from Brotli. So bad

https://github.com/google/brotli/issues/787

real where

My friend and I are trying to generate our own dictionary for BROTLI compression.... But nowhere is there a word about how to do it but the instructions directly say that it can be used ```-D FILE, --dictionary=FILE: use FILE as raw (LZ77) dictionary; same dictionary MUST be used both for compression and decompression ```https://github.com/google/brotli/blob/master/c/tools/brotli.md

https://github.com/google/brotli/issues/697 So nothing was done

It's good that the person literally wrote here that for ZSTD it is done like this - Whoop and done

I think Discourse forum is needed, or at least open Discussions tab in GitHub.

😏

it's this again

actually I think drama magnitude increases every cycle

🍿

i think it's hilarious how people are entitled enough to complain about this strike

what about going back to self-hosted php forums like the old days?

Or IRC ? interconnected individual servers is the future

we can set up a channel on pissnet, the most reliable IRC network

pissnet ?! really

that was a joke :p

Though I do run one of the servers so I can guarantee 90% uptime

About Win11 Auto Color Management (ACM): on what mode Windows Explorer works? sRGB mode, or monitor profile mode?

defaults everything to srgb

I vote we start looking into Lemmy as a federated Reddit alternative. I started a community on lemmy here: https://lemmy.ml/post/1404566

let me know if we want a better icon/banner, if someone should have mod, etc

I like Lemmy. It is federated, there are relatively decent clients available on Android w iOS stuff on its way, and AV1 has already moved to Lemmy

Yeah, and I believe it isn't coming back

Simulping & many others (including myself) are working on an AV1 wiki, & Montec (subreddit mod) wants to move everything there

The Lemmy will prob just be for news

Yeah, it's not coming back 😔

Great decision <:Poggers:805392625934663710>

real agreed

I personally hope Lemmy catches on, I like it a lot currently

Discord is a private chat, not a public board, so it's not a real replacement.

So louis is a web font

This scores 77 108

No real one 41 50

It's too thin to be a readable font

85 64

This is a readable programming font

This you can read at 80 fps to 160hz

Update with esme font I do 91 53

Readability is bad on YouTube Music app

With Promoteur regular I can do 123fps

Is good enough

But on readability is 37 less

So

86

And is low for PC usage

But I think that Galmur font 206 67

Max I can understand is 67 fps

92 133 I think
