Golden State and the Mathematical Magic of Seventy-Three - The New Yorker

What Google Learned From Its Quest to Build the Perfect Team - The New York Times
Quote: "As the researchers studied the groups, however, they noticed two behaviors that all the good teams generally shared. First, on the good teams, members spoke in roughly the same proportion, a phenomenon the researchers referred to as ‘‘equality in distribution of conversational turn-taking.’’ On some teams, everyone spoke during each task; on others, leadership shifted among teammates from assignment to assignment. But in each case, by the end of the day, everyone had spoken roughly the s...

How to Provide Great Feedback When You're Not In Charge
Quote: "There are at least three different kinds of feedback that may be appropriate in a given situation: APPRECIATION is expression of gratitude or approval of another’s effort. It is an expression of emotion, designed to meet an emotional need. ADVICE (or COACHING) consists of suggestions about particular behavior that should be repeated or changed. It focuses on the performance, rather than judging the person. EVALUATION is ranking the subject’s performance in relation to that of others or...

Here’s the other problem with Facebook and Twitter and even The New York Times. When you expose yourself to those things, especially in the constant way that people do now—older people as well as younger people—you are continuously bombarding yourself with a stream of other people’s thoughts. You are marinating yourself in the conventional wisdom. In other peop...

3 Timeless Rules for Making Tough Decisions
Great lifehack for making tough decisions: "If the issues on the table have been reasonably vetted, the choices are equally attractive, and there is still no clear answer, then admit that there is no clearly identifiable right way to go and just decide. It helps if you can make the decision smaller, with minimal investment, to test it. But if you can’t, then just make the decision. The time you save by not deliberating pointlessly will pay massive dividends in productivity."

How Medium Detects Hotspots in DynamoDB using ElasticSearch, Logstash and Kibana — Medium Engineering — Medium
Really cool next level analysis on database performance issues, ie: tools (New Relic for instance) these days make it easy to figure out if you have a slow query or a set of queries against a specific table that are slow... but in certain cases (and I've been there) you have 2% of the set of queries against a specific table that are accessing a 98% of the table, which causes huge perf issues.

People keep the conversation on topics where they won’t mind being interrupted. They don’t feel as invested in each other. Even a silent phone disconnects us."

Funny thing is that I don't see a note saying that thinking about milkshakes this way actually increased sales, but the "what job are you using this for?" way of thinking is helpful.

The Procrastination Matrix - Wait But Why
Quote: "And the thing the monkey really likes about Q4 isn’t anything about Q4 in particular—it’s that Quadrant 4 isn’t Quadrant 1 or 2. The monkey, whose core drive is to do whatever’s easiest, can’t stand the “important” quadrants, because the important quadrants are where the pressure’s on—it’s where there’s something to prove, where your actions have consequences, where the stakes are high, and where you’re shooting for the stars, which means you might fail to reach them. No fucking thanks, says the monkey. Writing 300 blog posts while I was supposed to be dreaming up brilliant business growth strategies wasn’t “easy” in the sense that I didn’t have to work hard to write them—it was easy in that there was nothing at stake. Stakes are really what’s hard for a human."

He said, it’s fine to disagree, it’s fine to push back, it’s great to have strong opinions and beliefs, but give my ideas some time to set in before you’re sure you want to argue against them. “Five minutes” represented “think”, not react. He was totally right. I came into the discussion looking to prove something, not learn something." via @cdixon

What has to happen for “X” scenario to be true? What are the risks and rewards of this scenario and how likely are they to transpire?

Futures of text | Whoops by Jonathan Libov
Excerpted excerpt: "Text is the most socially useful communication technology. It works well in 1:1, 1:N, and M:N modes. It can be indexed and searched efficiently, even by hand. It can be translated. It can be produced and consumed at variable speeds. It is asynchronous. It can be compared, diffed, clustered, corrected, summarized and filtered algorithmically. It permits multiparty editing. It permits branching conversations, lurking, annotation, quoting, reviewing, summarizing, structured responses, exegesis, even fan fic. The breadth, scale and depth of ways people use text is unmatched by anything."

Office, messaging and verbs — Benedict Evans
Lots of great stuff in here, excerpt: "Just as today we make web app copies of software models conceived for the floppy disk, so the first PCs were often used to type up memos that were then printed out and sent though internal mail. It took time for email to replace internal mail and even longer for people to stop emailing Word files as attachments. Equally, we went from typing expense forms (with carbon copies) to entering them into a Word doc version of the form, to a dedicated Windows app that looked just like the form, to a web page that looked just like the form - and then, suddenly, someone worked out that maybe you should just take a photo of the receipt. It takes time, but sooner or later we stop replicating the old methods with the new tools and find new methods to fit the new tools.  

Hence, channeling Marshall McLuhan, new tools start out being made to fit the existing workflows, but over time the workflows change to fit the tools."

sbdc » Time, and the managing there of
Quote: "I thought it was noteworthy that in Max’s conversation he commented that in some professions there is a time when work is actually done. When you finish X that’s all there is for the day. When I worked as a professional graphic designer in the 90’s that was often the case – I’d have done everything I could and next steps were waiting on something from someone else so I could call it a day. But now, with the web, and social sites, and constant email there is never an end. There is always a flow of new things to do, so unless you consciously decide that you are going to put it down and do something else for X hours a day, you won’t. And before you know it you’ll be dead and will have wasted your life chasing likes on Facebook.

Fuck that".
