Building Layoffs On A Healthy Foundation
- Kellan Elliott-McCrea
#Leadership #Management

tl;dr: "This is not a complete guide to doing layoffs. I think there is room and need for someone to write a definitive guide to doing layoffs well, but this is not that. This post is just some things I think about when I’m not in the middle of a layoff that I’ve found reduce the negative impacts when I do find myself in the middle of a layoff."

The Perfect Commit
- Simon Willison

tl;dr: The perfect commit is a single commit that contains the following: (1) A single, focused change. (2) Tests that demonstrate the implementation works. (3) Updated documentation reflecting the change. (4) A link to an issue thread providing further context.

tl;dr: We wanted to improve the coding experience for our development teams through infrastructure changes. We conducted research among 318 engineers and learned that: (1) Developer productivity and satisfaction were compromised due to longer build times, as per our Engineering Satisfaction survey results. (2) Build times on Apple silicon machines were 43% faster than Intel-based Mac systems, overall, and up to 50% faster for Android builds and 40% faster for iOS builds. And more. 
The Type System Is A Programmer's Best Friend
- Dustin Moris Gorski

tl;dr: "A string value is not a great type to convey a user's email address or their country of origin. These values deserve much richer and dedicated types. I want a data type called EmailAddress which cannot be null. I want a single point of entry to create a new object of that type. It should get validated and normalised before returning a new value. I want that data type to have helpful methods such as Domain() or NonAliasValue() which would return and respectively for an input of"
tl;dr: "One of my favorite parts of SSH is SSH Tunnels. With nothing but standard tools and often using just a single command, you can achieve the following: (1) Access internal VPC endpoints through a public-facing EC2 instance. (2) Open a port from the localhost of a development VM in the host's browser. (3) Expose any local server from a home/private network to the outside world."
