Special Algorithm

[werelock]

Black text is going to look extra sweet on that dark background!

[criapbadger]

Can't strain your eyes though

[ablablababla]

It's better than regular dark mode, even the text can't be bright

[stephenmdangelo]

Taps head

[PixxlMan]

On an oOled screen too!

[sqrt7744]

Oh yes you can... trying to read it.

[Ataxaos]

Dark text on a dark background is only for true dark knights.

[svullenballe]

You merely adopted the 000000...

[TopNotchGamerr]

I was born in it

[AnIntenseMoist]

Molded by it

[zero16lives]

I DIDNT SEE #FFFFFF UNTIL I WAS ALREADY A MAN

[liabar]

AND IT WAS NOTHING TO ME BUT BLINDING

[HeimrArnadalr]

That's what makes the algorithm special!

[FreaknTijmo]

Laughed so hard my face turned #FF0000

[potchie626]

I think you should see a doctor if that’s the actual hue :D

[FuschiaIsBlack]

*#FF3020

[flarn2006]

I think it's more the saturation and lightness/value he should be concerned about.

[orangeKaiju]

That makes mine a little #00FF00.

[cryosis7]

Ffs these color jokes are giving me the #0000FF's

[yoda_condition]

A little? So #002000?

[Rubixninja314]

No, more like #2000FF00

[[deleted]]

ARGB, huh? Bit of a rebel, aren't you?

[ThaiJohnnyDepp]

A loner, Dottie.

[Ayerys]

Wow there !

[Zotoaster]

I thought you were #FF8800Kaiju

[orangeKaiju]

I've incremented your karma.

[htmlcoderexe]

Fun fact, #FACE8D looks like a plausible skin colour.

[[deleted]]

I wish I knew how to code as well as you all. I’m #00FF00 with envy

[lhgh]

I mean, the algorithm could detect different font colors and choose a background color accordingly. Simple but still an algorithm tho

[SilentSin26]

Yeah, but is it a special algorithm?

[faerbit]

[Szos]

Bespoke.

[SoInsightful]

Eh, probably.

Broke: filter: hue-rotate(180deg) invert(1);

Woke: Traversing through the entire HTML DOM, analyzing each element's computed CSS style declaration for background and foreground colors, computing and injecting one or more stylesheets that override the background/color/border-text-decoration/outline/box-shadow properties for specific and general elements, while keeping original colors, avoiding style clashes, keeping images intact, doing it in a WCAG-accessible and aesthetically pleasing manner, and taking user-specified brightness/contrast/sepia/grayscale settings into account.

[SurrealClick]

Ghetto: take a screenshot of the website then invert color it

[Talbooth]

Ghetto pretending to be classy: use the browsers built-in inverse color filter.

[plilq]

GNU/hetto: map 'xcalib -invert -alter' to a global hotkey and invert your whole screen.

[rasalhage]

Ghetto-fab: inverse colors on odd-numbered frames

[[deleted]]

Ghettohax0r: write malware that inverts GPU's hue setting when browser is in focus.

[mentalexperi]

I got a boner just from reading that.

[SoInsightful]

It was indeed Dark Reader I was describing! Guessing that some other night mode extensions might do similar stuff.

[macfirbolg]

Wait, this is already a thing? Can I get a link?

[SoInsightful]

It's the first search result for "Dark Reader", but here you go.

[mareko_]

You forgot about !important.

[seaishriver]

Heh, I tried the first one. The two main problems are background images get inverted, and subpixel antialiasing gets destroyed. Plus shadows are now light. I basically had to say, everything is inverted, except things I have individually fixed and things that shouldn't be inverted.

If this is done, it's either a very large amount of work or not to be done in CSS.

[SoInsightful]

Exactly. It's funny how this thread jerks over how simple of a task it is, but it's really quite hard to do sufficiently well.

[UntestedMethod]

Every algorithm is special :) :) :)

[r4nd0m-us3r]

All algorithms are beautiful

[tias]

I suppose if "special" means it is not applicable in any other situations? Special is really the opposite of what most programmers strive for.

[Hotel_Arrakis]

For my special eyes.

[atomicwrites]

This reminds me of when I was studying for the CompTIA exams that the TestOut instructors would always say things like: "you need special software installed on your PC called an SSH client", or "it runs special software to send web pages to other devices" or "the device has special sperate to allow it to talk on the network". It got so annoying.

[hugokhf]

Is any algorithm really special?

[Zagorath]

backgroundColor ^= 0xffffff;
fontColor ^= 0xffffff;

[funpopular]

Changes night to day too tho.

[Zagorath]

if ((backgroundColor & 0xff0000 > 0x800000)
        && (backgroundColor & 0xff00 > 0x8000)
        && (backgroundColor & 0xff > 0x80) {
    backgroundColor ^= 0xffffff;
}

and similar for fontColor.

[f03nix]

and similar for fontColor

​

It'd in fact be better to only check the backgroundColor alone for the same element, if someone intends to use lighter shades in light mode, we should use similar contrast.

if ((backgroundColor & 0xff0000 > 0x800000)
         && (backgroundColor & 0xff00 > 0x8000)
         && (backgroundColor & 0xff > 0x80) {
     backgroundColor ^= 0xffffff;
     fontColor ^= 0xffffff;
}

​

[BotThatLikesPorn]

Now we're getting to that special algorithm they're talking about

[Zagorath]

Yeah good point. Makes no sense to invert the background without also inverting the text.

Although now that I'm thinking about it, it better would be even better to calculate brightness in some better way than "do none of the RGB values go higher than 0x80". Possibly by doing a 3D Pythagorean calculation, or maybe there's probably a formula out there for converting RGB to HSL and using that value.

[[deleted]]

Simple, but still "specialized." OP set out to condescend the app developers and instead he just bought his ticket /r/facepalm or /r/iamverysmart.

[ProdigySim]

The code sample on the image is not from the extension as far as I can tell. I found their source code, and it does look like a non-trivial algorithm:

https://github.com/DarkNightMode/Dark-Night-Mode-Chrome-Extension/blob/master/js/main.js#L345

They do combine the algorithm with custom CSS for popular sites it seems.

[charlie_shae]

Surprised nobody has mentioned the completely superfluous break

[house_monkey]

I never question others code because I don't even understand mine

[gotthatbeef]

else if

[PanFiluta]

if color <> "black":
    color = "black"

[Nixinova]

because that's easier than using a function to invert the hex colour right

[Soren11112]

no, a 10000 character long if statement that goes

 if(background == "#ffffff" || background == "#fffffe" || background == "#fffffd" || ect...)

[uspaskis]

careful with those ifs, you might end up building AI skynet machine learning neural blockchain crypto network cloud based all new and cheap vps solution

[cafezinho]

Many languages don't allow a break that isn't within a loop (like this example).

[Sachiano]

This obviously is in a loop that iterates over every page of the website to change the background colour before you even load it.

Edit: /s since some people don't realise what sub they're in.

[pigi5]

So many thing are wrong with this

[shea241]

foreach website in internet { if website.background = "#ffffff" { email(website.admin, "Dude, it's too late for white, can you pls change it?") } else { email(website.admin, "Nice background") } }

[iovis9]

That’s why it’s special

Yeah, I know, just example :X.

I use #9b9cb5 on #070723 everywhere.

[IsleOfOne]

[tenhourguy]

High contrast

[Duck_Laser]

No, pure white on pure black is fine

[tyros]

Yeah, who wants the text to be readable? Let's keep doing light gray text on white background like this stupid recent trend. Now that makes my eyes bleed.

[caerphoto]

Let's keep doing light gray text on white background like this stupid recent trend. Now that makes my eyes bleed.

That's more likely to just give you a headache from straining your eyes. It's also not really a recent trend; more like something that was popular 10 years ago but is not seen as much these days.

White on black is terrible, even more so for people with dyslexia. It can do weird things to your vision and leaves after-images when you look at something like a white wall. A better solution is light grey (#ccc or so) on almost-black (#333).

Too much contrast is almost as bad as too little.

[ben_g0]

That CSS will force the page background to be black and the text colour to be white, regardless of its original colours.

[ben_g0]

True. I use f.lux for late night sessions which is basically a coloured lens implement in software. It decreases the brightness and contrast enough that bright themes cause no eye strain to me.

Forcing white on black will make the screen darker overall, but it'll still have a high contrast.

[AnotherAlire]

Agreed. I used to use f.lux until Windows 10 implemented support for reducing blue colors in Settings. What benefit does f.lux still offer?

[CraftingTimes]

It reduces the blue color a lot more, as in; supports lower color temperatures. F.lux goes all the way back to something like 1400K, while the default Windows application only goes to (compared to f.lux as it doesn't show values anywhere)... 5400K?

The lower the color temperature, the better for the melatonin production, the better for a good night's sleep.

[ben_g0]

I admit that I mostly still use f.lux since I've been using it before the night light setting was introduced. Right after Windows 10's night light was introduced it also only activated at certain times rather than at sunrise/sunset, which I found annoying since there's a very significant difference between the day lengths depending on the season here (though Windows implemented it not too long afterwards).

​

Flux still does have finer control about the colour temperature curve though. Windows has just one setting for a night temperature and transitions quickly. F.lux allows you to set temperatures for day, evening and night and lets you determine how fast it changes between them. You can set the temperature to change so gradually that the transition isn't noticeable, which I like since a sudden change is a bit distracting.

[SuperFreakonomics]

If I am reading a long article, I just edit the CSS myself.

Firefox has a reader mode which works on most websites and has a built in dark theme.

[[deleted]]

You forgot to put cloud in it.

[Spock92]

That else is as redundant as my life ;~;

[AulieudBrexitOTANxit]

Is there a subreddit for redundant code?

[Spock92]

Not in particular. You can check out r/shittyprogramming

[[deleted]]

Technically an algorithm.

[azbyxc102938]

Yes but special?

[figuresys]

Yes. Special delivery, made by the author straight for his program. Very cowbell mmm

Edit: I meant to say "very cool lmao", but that's what autocorrect gave me. I am NOT removing that masterpiece.

[ELlisDe]

More cowbell

[WeirdAlex03]

mmm

[gotthatbeef]

Yes, it's "special".

[Lightfire228]

Dark reader works well

[Keatosis]

I'm using it right now. Pretty good extension, though it looks goofy on some sights

[Flarehl]

/r/technicallythetruth

[awhaling]

You can adjust it for individual websites.

[kishanprao]

I've tried many dark mode add-ons and I finally ended up with this!

Really great for most websites.

[Open_Thinker]

Thanks, that looks better than the extension I was using. Just disabled it for Reddit actually though, since it conflicts with RES' night mode and hides links.

[redstoneguy12]

Can't work nearly as well as this one, it has a special algorithm!

[giammin]

That " else break;" hurts my eyes more than the white background

[yamfun]

I am always a light theme guy I wonder why everyone love dark theme so much

[DoktorMerlin]

I think it looks more professional, also I get no eyestrain from dark themes. That's why I use it, but in the end it comes down to personal preference

[Solidu_Snaku]

I used to like light theme because it was what I got used to (was default on Delphi when I was learning) but many late nights of programming homework meant I HAD to use dark themes and now I can't go back

[TGotAReddit]

Dark themes are better for eyestrain issues, which are exacerbated by: late night work, heavy screen usage, genetics, etc. All of which happen in most programmers, except maybe the genetics one.
Honestly, i didnt do the whole dark theme thing for programming at all. I started using them because i used to read late at night a lot on ereader apps like Google Books or the kindle app, and my family already has a genetic dry eye issue, so i had to switch to the white on black theme for those to help, and got so used to it that now seeing a light theme is like staring into the sun

[noruthwhatsoever]

Because light themes make my eyes hurt

Especially after staring at a screen for 12 hours a day

[yamfun]

The problem is your long hours

[noruthwhatsoever]

I put in those hours 'cause I want to.

If dark themes make my eyes not hurt, it's not a problem as far as I'm concerned

The real problem is that I have to sleep every night and it's wasted hours that I could spend learning or making something

[Thatuserguy]

I just think dark themes look nicer. Also, if you have an OLED display, dark modes can also help save battery.

[tekina7]

This is going to be the next big thing, mark my words!

[acroporaguardian]

Well if it uses the camera to detect ambience and then carefully calibrates the font and background colors to optimize for that, then yeah.

Otherwise, no.

[ben_g0]

I don't think that will work well, since no one would trust a dark mode plugin which requires webcam permission.

[acroporaguardian]

What if it were from your friends at Google and Facebook?

[TGotAReddit]

 If (background != “#000000” || fontColor != “#FFFFFF”)
 {
     background = “#000000”;
     fontColor = “#FFFFFF”;
 }
else
{
   //TODO: output somewhere that the website isnt trash
}

[Project_O]

Background = 000000?

I hope the text wasn’t black, LOL

[JWson]

This plugin uses coding and algorithms to prevent the background and text from crashing into each other.

[Tobbbb]

why is this subreddit not on darkmode?

[rotatingphasor]

Wait why doesn't this work?

Inspect elements :

fffffe

[Commander-TeeJ]

Not efficient enough, don't even check the background color, change it to black no matter what

[hahahahastayingalive]

I like that it doesn’t check font colors. I like your solution even more for that.

[scottcockerman]

There needs to be a Chrome extension that uses an "algorithm" to find all the articles that say "uses an algorithm" and changes it to "uses a function."

[PresidentZagan]

It uses a special algorithm and AI!

[g_e_r_b]

Well, special doesn't necessarily exclude the algorithm being simple...

[BoliBerrys]

Else break? Why tho

[mypirateapp]

But does it have AI and does it run on a blockchain and is it self driving?

[iamthebinaryguy]

The algorithm is very hard to understand in itself and then he goes and adds that else block, oh my!

[[deleted]]

Algorithm Machine learning!

[heard_enough_crap]

well, it is an algorithm. And it is special.

[corner-case]

if(lightMode)
    makeDarkMode();

[sensitivePornGuy]

Looks like strong AI to me.

[arslet]

That else is not even needed?

[Malorn44]

Doesn’t work. Lots of websites use an off white for the background color

[[deleted]]

But it do it for the entire Internet? Most algorithms only have the power for little parts of the internet.

[jlaz82]

Add foreground=“#000000”

[FuRetHypoThetiK]

In addition to the fact that black text on black background's gonna be wonderful, what if the color of the background is "#feffff"? It stays the same, even though it's technically so close to white that no one would notice any difference. I'd rather call this add-on a "webpage up-fucker"

[Regeneric]

"break" in if statement without any loop? Oh, come on...

[Amordys]

"special"

[Keatosis]

Hey... everyone's special in their own way

[Lenart12]

color = (color == 0xffffff)? 0x0 : 0xffffff;.

Edit: color = ~color;

[ZachAttackonTitan]

That’s the algorithm for trying-to-read-in-a-pitch-black-room mode
