Have you considered that your opinion on the best way to serve data to a billion users might actually be wrong? That maybe Facebook actually knows what they are doing?

This is the company that bragged about having 18,000 classes for their iOS app [1] and having to patch the Dalvik Virtual Machine to support new features in their Android app [2]; they are not infallible.

IiRC they aso exploited an Android bug to give themselves more memory. Facebook is woefully buggy and slow that many people are now either using the website or alternative wrapper apps that don't drain their battery immensely.

My favorite part - > This friend recommended nvd3.js, presumably because you’re not making real graphs in 2016 unless your graphing library is .js and requires at LEAST one other .js as a dependency. Everyone looks at you like “what, you DON’T already use .js? Jeez say goodbye to your Hacker News karma. Just apt-get install npm && npm install bower && bower install-” NO STOP IT THIS ISN’T WHAT TIM BERNERS-LEE WANTED”…

Indeed, the article was a great and humorous stream-of-consciousness.

For me, it was this:

You used to be able to do this with the Facebook Query Language (FQL) that Facebook exposed, sending something like this query to the FQL endpoint.

   SELECT uid, name, online_presence
   FROM user
   WHERE online_presence IN ('active', 'idle')
   AND uid IN (
     SELECT uid2 FROM friend WHERE uid1 = me()
   )
Unfortunately, the current version of the Facebook Graph API[0] doesn't have the online_presence field, so this is no longer possible. Maybe the Graph API will be updated in the future to also return the online_presence fields?

Really? The notifications and the first story show up fairly quickly for me, but everything else usually takes a few seconds. Certainly not terrible, but I wouldn't call it "ridiculously fast" either.

0.3 seconds for me, just now. HN was 1.3 seconds.

Really?

FB just took 13 seconds for me to load fully! HN took only a second. I suspect the situation would be way worse if the browser cache was cleared too.

> Actually it is: https://www.facebook.com/notes/facebook-engineering/bigpipe-....

Nope. Did you read through how BigPipe works? It's more than a handful; they basically load a whole bunch of mini web pages inside of another. I'm actually impressed they get better performance doing that; I would have thought condensing everything down would net much better performance. It would at least improve latency but I digress.

Do you have stairs in your house? (i.e. do you browse SomethingAwful, because your style of sarcastic humour is pretty similar, going by your writing & the animated frog on Swagify, and yes yes i know the rules of HN...)

I love this guy's humor. I remember when I was 17 I used to write a column for flipcode.com where I thought I was being pretty funny in appropriate amounts ( http://www.flipcode.com/archives/Theory_Practice-Issue_06_Ev... for example) but I like his jokes more! But hey, I was 17 and also it was me so... I'm biased.

I used to read those articles! Fond memories.

What's with the ellipses? Always so awkward reading messages from people who always do the ellipses thing.

I think in some cases it is because people are taught that Comma Splicing Is Bad. But imo Ellipse Splicing Is Worse (and should probably be Considered Harmful ;) ). Commas or Em Dashes[0] are better, clearer, and (AFAIK) more grammatically correct.
