Managing People
- Andreas Klinger
#Leadership #Management

tl;dr: "Your job is not to manage people, but to manage processes and lead people." The CTO at OnDeck provides advice on all management topics in short, bullet, form ranging from creating trust through transparency, avoiding "drive-by management," how to give feedback, and more.

Managing Yourself
- Subbu Allamaraju
#CareerAdvice

tl;dr: "You’re the CEO of yourself — a one-person enterprise — act like one." Subbu realized that "managing yourself includes managing your internal state" i.e. how you feel about yourself and others, your emotions, time, relations, etc... yet most are not aware of their internal state. A CEO rarely runs the company based on that morning’s news, social media chatter, or the stock ticker.


"I do not fear computers. I fear the lack of them."

Regexes Are Cool And Good
- Hillel Wayne
#Regex #CareerAdvice
 
tl;dr: People hate regexes for 2 reasons: (1) They’re hard to read, so it's hard to tell what a regex does. (2) They’re fragile an a slight change to the input can break it and making them more robust is tough. Hillel argues that the best use cases for regexes is in "interactive use" - when you’re trying to substitute in a single file you have open, or grep a folder. "Readability doesn’t matter because you’re writing a one-off throwaway, and fragility is fine because you’re a human-in-the-loop."
#PostgreSQL
 
tl;dr: "I was trying to understand how PostgreSQL stores the data onto the disk and there are a few interesting things that I have noticed that might be useful for application developers. In this post, I will try to go into the implementation level details and map out how PostgreSQL row storage really works."
How UTF-8 Works
- Seth Michael Larson
#Unicode

tl;dr: "I recently learned how UTF-8 works and felt that the definition lended itself perfectly to creating diagrams explaining the implementation. I created these diagrams for my own enjoyment and wanted to share them. Hopefully this will inspire you to learn how other low-level protocols work too!"
I Relearned Typing To Save My Wrists
- Gregory Witek
#CareerAdvice #Management

tl;dr: "With help of Ergodox keyboard and Colemak layout I changed my typing habits and saved my wrists from severe pain."
