The Hidden Power Of Momentum
- Paulo André
#Leadership #Management

tl;dr: "When an army has the force of momentum, even the timid become brave; when it loses the force of momentum, even the brave become timid.” Building momentum is about increasing velocity - speed and direction. Leading is about increasing: (1) confidence in the direction i.e. vision, planning, strategy. (2) speed at which you're moving i.e. execution. Paulo discusses practical ways to achieve momentum.
Start Test Names With “Should”
#Tests #CareerAdvice #Naming

tl;dr: Reasons include: (1) It removes redundancy, because the function name should already be in the call stack. (2) It is falsifiable i.e. a person reviewing the test can decide to which degree the name agrees with the actual test. (3) Encourages testing one property of the function per test.

#Management #Security

tl;dr: Proactively demonstrate your commitment to security, externally and in real-time with the Vanta Trust Report.

tl;dr: "If positive engineering is taken to mean the day-to-day work that engineers do to deliver productive, expected outcomes, then negative engineering is the insurance that protects those outcomes by defending them from an infinity of possible failures." Jeremiah discusses the impact on productivity.

Uber’s Unified Signup and Login Stack
#Architecture #Uber

tl;dr: "Over the years we’ve built independent signup and login experiences for each of our lines of business which allowed us to innovate and move a lot quicker. However, as we scaled and added additional lines of business, our experiences began to diverge leading to some of these inconsistencies being amplified."
The Day I Wiped A Production Database Table
- Paul Boyd
#Database

tl;dr: "I was 6-months into my first real developer job, trying to fix a bug. Our application would sometimes insert rows with an invalid “foreign key.” Of course, the bug was only seen in production, so I had a production MySQL shell open to see the bad rows."

Python 3.11 Performance Benchmarks Are Looking Fantastic
- Michael Larabel
#Python
