Trunk and Branches Model for Scaling Infrastructure Organizations
- Will Larson
#Leadership #Management #Infrastructure

tl;dr: Early on in your company’s lifetime, you’ll form your infrastructure organization: a small team of 4-8 engineers. Later on, you'll have 70 engineers across 8-10 teams. Those are both stable organizational configurations. The transition between the small to the large team can be difficult and unstable, and Will provides us with a playbook on how to execute it. 
Delegation Is An Art, Not A Science
- Lara Hogan
#Leadership #Management

tl;dr: Lara provides a "delegation template" that prompts the manager to describe, in one sentence, the outcome they want to see, as well as 3 phrases to complete when delegating: (1) "I will support you by…" - aim for 2-5 actions on how to provide support. (2) "You should reach out to me when…" - how and when the report should connect with you. (3) "This will be a success when…" - make this measurable and time-boxed.

What Is Developer Experience? A Roundup Of Links And Goodness
- James Governor 
#DevEx #Management

tl;dr: "DX is about developer feelings – it is a sociotechnical system which should consider every touchpoint a developer interacts with to plan and produce software, from learning a platform to the very first line of code all the way through its promotion into production."

"Code never lies, comments sometimes do."

— Ron Jeffries

Editing Stuff In Prod

tl;dr: "This was someone who had been asked to give haircuts to hyperactive children and had only been handed a chainsaw, and still managed to actually DO it without harming or scaring anyone. That takes some serious effort (and skill)." The author discusses working with another individual who had to edit in prod.

The Technological Case Against Bitcoin And Blockchain
- Luke Plant
tl;dr: "Cypto-mania is not really about technology. If you want to understand what is going on, you need to understand it at the level of economics, culture and human nature." Luke asks the following 3 questions to evaluate cryptocurrencies: what problem does this try to solve? Does it actually solve it? What costs does it bring with it?
tl;dr: "This is the story of CVE-2022-0847, a vulnerability in the Linux kernel since 5.8 which allows overwriting data in arbitrary read-only files. This leads to privilege escalation because unprivileged processes can inject code into root processes."
Algorithms For Modern Hardware
- Sergey Slotin
#Hardware #Algorithms

tl;dr: "This is an upcoming high performance computing book. Its intended audience is everyone from performance engineers and practical algorithm researchers to undergraduate computer science students who have just finished an advanced algorithms course and want to learn more practical ways to speed up a program."
