Unrolled thread from @patio11
“Some people really benefit from hearing advice that everyone knows, for the same reason we keep schools open despite every subject in them having been taught before.” Mostly related to the tech business.</p>

In that spirit, here’s some quick Things Many People Find Too Obvious To Have Told You Already.

Your smartphone is making you stupid, antisocial and unhealthy. So why can’t you put it down? – The Globe and Mail
We’re doomed! Interesting for this bit: “It takes office workers an average of 25 minutes to get back on task after an interruption, he notes, while workers who are habitually interrupted by e-mail become likelier to “self-interrupt” with little procrastination breaks”. That’s true of me: if I’m constantly getting interrupted I give up and procastinate in anticipation of the next interruption.

How evolutionary biology makes everyone an existentialist | Aeon Essays
“Each variant of human desire is ‘natural’, not in the sense of being required, but only of being made possible by nature. And it is in what nature makes possible, not in what it necessitates, that we should look for the answer to the question about what we should be or do.”

Recommendations please: Is there more to Belief than Credence above a certain threshold? : askphilosophy
Apparently, the thesis that this is all there is to belief is known as the Lockean thesis and is regarded as wrong. Some interesting references to dig into.

Inspiring Philosophy and the Laws of Logic: Part 1 – UseOfReason
What could apologists be talking about when they speak of “the laws of logic”? (This is usually part of an argument that God is needed for there to be such laws). Discusses various different logics, what Godel really proved, and a bunch of other stuff.

Thin Pinstriped Line: The business of Remembering
Veteran and civil servant “Sir Humphrey” on poppies: “I have grown increasingly concerned at the manner in which manufactured outrage focuses on any organisation or individual that challenges the Poppy status quo, by not wearing one. If you are wearing one only because everyone else is wearing one, then perhaps it is time to ask whether the Poppy has become a victim of its own success.</p>

As we move into the world where we are over a century on from the events of WW1, perhaps the time has come to ask if it is time to evolve the service of Remembrance, and perhaps do it differently. I do feel that the need to remember is always appropriate, but that the means by which a simple silence has become a business and outrage outlet to sell papers is increasingly distasteful. “

What every systems programmer should know about lockless concurrency
“Seasoned programmers are familiar with concurrency building blocks like mutexes, semaphores, and condition variables. But what makes them work? How do we write concurrent code when we can’t use them, like when we’re working below the operating system in an embedded environment, or when we can’t block due to hard time constraints? And since your system transforms your code into things you didn’t write, running in orders you never asked for, how do multithreaded programs work at all? Concurrency—especially
on modern hardware—is a complicated and unintuitive topic, but let’s try to cover some fundamentals.”

I’ve updated the little script I wrote to keep track of which comments are new on LJ and Dreamwidth (LJ now does this automatically in its default style, DW doesn’t, by the looks of it). Thanks to various people for telling me it was broken for HTTPS sites, which LJ and DW both default to these days.

Userscripts.org is long dead, so I’m now hosting it on my site.

A very British dream | Richard Seymour on Patreon
“Problem number one for the Conservatives is that they no longer have any idea how to administer capitalism. No viable long-term growth strategy avails. They can’t address the financial sector without hurting their allies in the City. They can’t address the crisis of productivity and investment without more state intervention than they’re willing to accept. They can’t address the housing crisis or the precarious debt-driven economy without harming the interests of home owners. They can’t build new support in the rustbelts on an anti-immigrant basis, without sacrificing affluent swing voters and particularly ethnic minority voters in big cities and marginals.”
