JohnBerea··on Facebook fires employee for publicly scolding a colleague
Is the history of that phrase commonly known? That long and detailed Wikipedia Article was only created after Trump said the phrase:

> Trump’s posts included the racially charged phrase “when the looting starts, the shooting starts”

How is that racially charged?

In related news, the existence of biscuits and triscuits hints at a third food known as monosquits.
JohnBerea··on Not everyone has an internal monologue
People without an internal monologue: Are you able to listen to a spoken sentence and then replay that sentence in your head? Do you have any audio-type memories?

If so that's basically what it's like for the rest of us, just with the words rearranged into whatever sentence we're thinking.

JohnBerea··on Not everyone has an internal monologue
It's not necessarily either-or. I have an internal monologue for most things but much of my math and programming thoughts are conceptual.
JohnBerea··on Shared Cache Is Going Away
This is a wonderful idea. You could also opt-in client-side with a shared attribute:

<script shared src="//:jquery.com/jquery.js"></script>

JohnBerea··on New universe of miniproteins is upending cell biology and genetics
Such mutations are highly popularized and simultaneously very rare.
JohnBerea··on New universe of miniproteins is upending cell biology and genetics
The human genome is full of harmful mutations. While many are widespread and some are shared by everyone, we each still have our own unique collection of them. I often wonder how much longer we'd live with every obviously harmful mutation reverted.

And alternate splicing is a form of compression, where exons store the repetitive parts of genes only once, to be combined to make many proteins.

JohnBerea··on Ask HN: How comfortable do you feel using cloud-based password managers?
I just use KeePass, and Syncthing to automatically sync its encrypted password file (and other files I care about) to my android phone and all my windows computers. No cloud needed.
JohnBerea··on Why Do Computers Use So Much Energy?
The brain still tops every CPU at visual processing, which may be its highest throughput interface.

In addition to f.lux, I also use the Dark Reader Chrome extension[1], which dynamically generates dark themes for every page you visit. It seems to make a bigger difference than using f.lux.

JohnBerea··on Zuckerberg in Holocaust denial row
I've debated several holocaust deniers and I've never met one who was deliberately lying. It's a dangerous world when we make it "illegal and punishable" to be wrong.

> Editor of anti-fascist magazine Searchlight Gerry Gable told the BBC: "Zuckerberg could kill much of this dangerous material getting worldwide distribution - but he is a like a spoilt teenager."

It's a strange world when the "antifascists" want control of speech.

JohnBerea··on Mysterious ‘Jumping Gene’ That Appears 500k Times in Human DNA
If you need to make deliveries along the whole path from NY to Chicago to Philly, the path makes sense. If the road is necessary to anchor Chicago and keep it from floating away during the development of the United States, that's another reason, although our analogy is becoming strained lol.

If you are missing either of the superior or recurrent laryngeal nerve, you can still speak, although not as well as if you have both. Doctors use this hoarseness as a diagnostic for various chest issues.

United Airlines Flight 232 also illustrates the importance of running redundant cables through different paths. One piece of shrapnel pierced all three hydraulic systems on board, and nearly half the passengers were killed.

JohnBerea··on Mysterious ‘Jumping Gene’ That Appears 500k Times in Human DNA
The article you quoted says "there seems to be no apparent benefit to an extensive routing of the nerve supplying the larynx," but it doesn't mention or address the three reasons I cited above.
JohnBerea··on Mysterious ‘Jumping Gene’ That Appears 500k Times in Human DNA
On the recurrent laryngeal nerve in mammals: A direct route to the larynx already exists through the superior laryngeal nerve. A second path provides redundancy if one is damaged (e.g. by disease or developmental defect)

The nerve innervates the deep cardiac plexus at the bottom, and the esophagus and trachea on its way to the larynx. So the path needs to be run anyway, leaving little advantage to another route.

Gray's Anatomy (the book, not the tv show) says during development the recurrent laryngeal nerve provides "a means of support that would permit the ductus to develop as a muscular artery" which it can do because it "has a greater proportion of connective tissue than other nerves, making it more resistant to stretch." Having a single cell build itself into a giraffe (or human) requires scaffolding along the way, and having the scaffolding that is also reused as a functionally redundant component of its own is better design than if it were not.

The inverted vertebrate retina is needed to allow additional cooling through blood flow. This article goes into additional tradeoffs in the design: http://www.quarkphysics.ca/scripsi/vision-of-octopi-and-the-...
