How "Engineering-Driven" Leads To "Engineering-Supremacy"
- Charity Majors
#Leadership #Management

tl;dr: Companies that describe themselves as engineering-driven tend to fall into 2 traps: (1) They alienate the business side showing little interest in other functions, such as sales or marketing. (2) Act like engineering is superior to other roles in the company. Charity hires engineers that show interest in the business, and believes that caring for the business is a "learnable skill" highlighting the tactics used at her company. 

Make Debugging Suck Less. Keep A Logbook.
- Connor Lamb
#Debugging #CareerAdvice #Tips
tl;dr: "Scientists keep logbooks for their findings. Why don’t computer scientists?" Conor shares an example of one and cites these benefits: (1) Enumerate where you are in the bug fixing journey. (2) Keeps you rooted when you have a stack of issues. (3) Makes your future steps clearer. (4) Documents the time and effort spent, helpful to show your team the energy you put in. (5) Documents your eventual success and how it happened.

"The tools we use have a profound (and devious) influence on our thinking habits, and, therefore, on our thinking abilities."
— Edsger W. Dijkstra
tl;dr: "How PostgreSQL row count estimation can go very wrong. In this case, domain knowledge will help us trick PostgreSQL into a different query plan which will be way faster, without adding any additional indices." Jacob shows us that query plans aren’t that hard to interpret with the right tools and how to rewrite queries to "achieve substantial performance boosts without unnecessary indices or denormalizing the data model."
An Extremely Casual Code Review Of MetaMask’s Crypto

tl;dr: "This post describes a very casual code review of a few cryptography functions used by MetaMask. It does not describe any vulnerabilities. If you’re the kind of person who likes a meandering and amateurish code review that goes absolutely nowhere, you’ll enjoy this post."
