It's not a natural place for him to post. He was bought. From what I've seen of the guy, the natural place for him to post would be in a .plan file somewhere.
There's nothing wrong with posting a technical article on Facebook, especially if you're too busy being a graphical programming genius to set up your own blog somewhere. I don't see it as any different than posting on Medium...besides making a choice as to which company you're going to support? But seriously, who cares?
The only thing wrong with it is that you generally have to have a Facebook account to read Facebook content, which means you have to give them your real name. It appears that this month Facebook is allowing people to read this particular post, but they aggressively put the sign up wall wherever they thing it will generate the most conversions. You certainly can not see John Carmack's past posts without a Facebook account. Facebook is not the open web.
Technically you can violate the ToS and set up a fake account, but that's a bit of an inconvenience

fold --spaces --width 75 | sed -e 's/^/ /' In almost all of the public VR critiques I have made, I comment about aliasing. Aliasing is the technical term for when a signal is under sampled, and it shows up in many ways across graphics (and audio), but in VR this is seen most characteristically as "shimmering" imagery when you move your head around, even slightly. This doesn't need to happen! When you do everything ri…
TIL 'fold', thank you. I've always been a big fan of including the command you use to get the output you're quoting - people sometimes pick up even subtle tricks or flags from doing this.
Oddly this is one of the tricks in Programming Pearls that I love, but can't get others to want to do.
It doesn't help that json prohibited comments. So, anything that modified json is incapable of adding a breadcrumb of what it did.

Whether or not a post is available to "the public" (signed in or not) is completely the choice of the author, not some mysterious committee at Facebook.

> as Facebook cozies up closer and closer to Oculus and gang. My understanding is that Facebook has “geared up” Oculus: added a lot of staff. I would assume that a majority of engineers who are working on VR were originally Facebook hires; it’s certainly the case for things like back-end / scaling. It’s not the most visible part of the company, but when Mark says publicly that a project is a priority, that means that…
I was referencing blog posts that ought to be on a blog, not in a Facebook post. Just because someone has worked for Facebook, or currently works for Facebook, doesn't make posting these sorts of articles on Facebook ideal. Even Facebook knows this... which presumably is why they chose to use a traditional blog style site for their... blog posts[1]. [1] https://developers.facebook.com/blog/
Like it or not, when someone is a public figure, their posts on Facebook get LOTS of views. A larger percentage of internet users ONLY read Facebook these days.
Carmack's profile has almost 10,000 followers and several hundred 'friends' each of which will have been pinged about the new post immediately. Even a popular blog won't be able to do that, that instantly. So you can see the attraction.
Also, on Facebook there is the concept of 'Notes' which are better for long form writing and display in their own large overlay div. Not sure why Carmack didn't use it.
I am not a fan of Facebook, but from a technical point of view the platform does have its merits.

Can you format text (eg different fonts for code snippets) in facebook posts?

Have you tried to read a page on facebook without an account? It's intended to be an almost unusable experience.
On loading a page, I get a modal popup obscuring all content insisting I "register" or "login", with a "not now" option. Then when you click "not now", the bottom third of the screen is obscured by a fixed overlay.
It is loosely describable as readable, but in practice, it's a fight to read it. The element has randomly generated id, so can't easily be blocked with ublock or similar.

indeed: inspect element -> style='display: none' should not be mandatory to read a page. Grease monkey is an option, but still.

#79New project: A script that extracts public posts from Facebook for a given user, and formats them for consumption via RSS, or generates content/markdown to be served by Jekyll/Lektor. I should get on that...
Might I humbly suggest a project name? FFSS. For F(acebook|uck)'s Sake Syndication. :)
Once upon a time Facebook had RSS/Atom feeds as in https://www.facebook.com/feeds/page.php?id=12183340&format=a...

#80What's the problem with specular lighting on bump maps? I think I see what the issue can be, specifically, that when the bump map texture is smaller than 1-1 texels-to-pixels, then the normal chosen will 'shimmer' between the possible texel values. But can't one use mipmaps for bump maps as well to reduce this?
