For most of software’s history, the limit on what you could ship was your hands: how fast you could type, how much you could get built before the day ran out. Agents lifted that limit. A developer can now run several streams of work at once and get through more in an afternoon than used […] The post...

Want the unique key-value pairs from two Python dicts? dict.items() returns a set-like object: This returns the unique key-value pairs: {(‘b’, 20), (‘a’, 10), (‘d’, 40), (‘c’, 30)} The post Python dict.items(): Set operations on key-value pairs appeared first on LernerPython.

The goal of this post is to answer a simple question: why are the following two definitions of the vector dot product in Euclidean space [1] equivalent for vectors \vec{a} and \vec{b}: Component definition: \vec{a}\cdot\vec{b}=\sum_{i=1}^{n}a_i b_i Geometric definition: \vec{a}\cdot\vec{b}=|\vec{a}|...

In the last few months every engineer I hired stumbled in exactly the same way: Project management. They learned quickly, but that first big project has become a rite of passage.

In short: I prefer strict tables in SQLite because they avoid some datatype problems, such as putting text in number columns. SQLite has a feature that I think is underrated: strict tables. Strict tables help enforce rigid typing, preventing mistakes like putting text into integer columns. I like th...

With the three last problems significantly harder than the first two, it all came down to choosing the hard problem that fits one's strengths the most, as ...

Give an agent better tools and it should do better work. That’s the instinct, anyway. When you open a pull request, Copilot code review reads the diff and explores the surrounding code to find the problems that matter before they ship. To do that, it used its own code exploration tools. So when we s...

How migrating Copilot code review to shared Unix-style code exploration tools reduced review cost by reshaping agent workflows around pull request evidence. The post Better tools made Copilot code review worse. Here’s how we actually improved it. appeared first on The GitHub Blog.

Over the years, I've built up a collection of aliases, shell functions, and CLI tools that make my terminal feel like home. All of it lives in a single repository: my dotfiles. It's a backup of every terminal tool and configuration I rely on, and it means I can set up a brand new Mac from scratch in...

Coding agents are getting pretty good at building screens from a screenshot, Figma link, or a loose description of what you want. But “pretty good” can still mean a lot of small cleanup work: the button is almost right, the spacing is close, the font weight is questionable, and the loading state som...
