The source you sited as stating 66 characters being "ideal", has an approximate average of 134 characters per line.

Here’s roughly what it’s supposed to look like, http://i.imgur.com/yOndq70.png Your browser window is just too wide. With such an oversized browser window, a substantial proportion of content on the web, perhaps the majority, is going to have an absurdly wide measure to the point of extreme illegibility. I highly recommend narrowing your window; as a general rule it will dramatically improve web typography. HTML/CSS…

> I highly recommend narrowing your window; as a general rule it will dramatically improve web typography.

That will have the side effect of knocking most sites into "responsive" mode, giving you less of a desktop experience than you believe you're getting.

My monitor is 1920x1080, a fairly standard desktop monitor resolution. Narrowing it back to 1024x768 or something will give you a poorer experience on most modern websites.

I do believe this "typographical style" is more relevant for printed material with smaller font sizes.

i can read it logged out of facebook unfortunately there is an annoying box covering up 1/3 of the page asking you to login or signup. it does not "block" any content in that you can still read all of it. but it is highly annoying (and i assume purposely so).

The main question is why Carmack doesn't use the Facebook Engineering Blog. There are no popups or other annoyances there. For example: https://code.facebook.com/posts/265413023819735/surround-360...

Facebook employees generally communicate internal results or opinion with Facebook posts, a lot like this, using a Company-only privacy setting. Posts like this one sound like something he posted internally first, and just reposted, or changed the privacy setting. I wouldn’t read any more into it than marginal laziness.

You just wrote Facebook Fuck's Sake Syndication with 1 extra character, and with more reading difficulty!

Looks like you need to brush up on your regular expressions. > For F(acebook|uck)'s Sake Syndication The pipe (|) means or, so the regex is indicating that FFSS can stand for either: For Facebook's Sake Syndication, or For Fuck's Sake Syndication I thought it was clever, anyway.

I don't know about clever, but it's a common idiom on tech forums.

OLED is the issue. Look into the black smear problem on Oculus DK2 and how they had to half-way fix it by overdriving for a frame and then falling back. CV1 of the Rift headset is OLED and has the same issue. They have to run the panels at a notch above minimum brightness to work around it and as a result they lose out on true blacks. https://vrwiki.wikispaces.com/Black+smearing

None of those threads mention the Rift CV1, the Vive, or the Samsung Galaxy S6 or S7 (the ones that fit in the current Gear VR headsets). I tried the test image from this thread http://forum.xda-developers.com/showthread.php?t=2765793 on my S6 and didn't see the issue. That thread and this one https://forums.oculus.com/community/discussion/10924/true-bl... say it's only an issue around areas where the screen is actua…

I think I wasn't clear. It isn't a notch above minimum brightness as in running the panel very dim.

It is a notch above minimum as in: minimum is pure black, and instead of every allowing pure black they set it to one notch higher, because pure black causes the smearing.

It isn't an visible issue in Rift CV1 or Vive because they do that as a workaround.

I do this a lot of the time, too. And I believe it is ridiculous to have to do it... Yes, I'm grateful that browsers today make it easy to pwn the DOM. And it is disgusting that this is often necessary to avoid spammy website behavior. People who don't understand browser internals are forced to contend with popups and forced registration to unveil content indexed by search engines. Yep I'm looking at you Quora. Thank…

Yeah, the Google query text is an oft-broken contract. I presume there is some German word that describes the feeling of searching, seeing what you want right there, bolded in the result text, and doing a CMD-F to search for it on the page, only to hear the plaintive beep of 0/0 results.

English doesn't have a word for Suchmaschineauswahlempfindungsfehlerschmerz?

(disclosure: not actually German)

Carmack: Some times you read HN. If you are reading this, please consider writing on a blog or something neutral. It is extremely disgusting for your readers to have to log in or else...half of your screen is occupied with spam. There is people out there that prefer not to report everything they read, when, where, how, how long to a big multinational associated to the US secret services.

"Extremely disgusting" sounds like an overreaction. "Not ideal" maybe, or "not helpful to those of us who don't want to read things in Facebook for privacy or security reasons". But "extremely disgusting" is over-exaggerating the importance of the choice of medium for a text post.

I was going to say "criminally atrocious" but then the popup div literally made me vomit excrement.
