As I’ve discussed in the past, Microsoft Edge is a superior browser and in supporting that title, it allows you to add multiple search engines to your address bar. This week, I added Exa.ai as an option with the prefix exa. Note In the past, I’d prefix my prefixes with @ (ex. @ai, @exa, @x) but its faster to omit that and use the prefix directly. ...

In the past, I would always open new projects in VS code by navigating to them and running the simple and famous command: code . This command opens a new window with your project, leaving everything else untouched except for your system’s memory usage.

[{ role: "assistant" as const, content: functionResponse }] : []), ];

To do it, simply append -- after the npm script and then add your arguments as you would if you were running the script with node: npm run start -- --foo=3

After a 15 minute, AI-assisted troubleshooting session, I squashed a bug after realizing I was calling .pop() on a TypeScript list a few turns before I was attempting to print out that list. The result? A list that was missing the very last entry. The .pop() method is mutating or destructive because it directly modifies the array it operates on.

Contents I use Firebase Remote Config to manage AB tests in most of my software projects. Boolean AB Testing Whenever I want to run a new AB test, I create a new boolean parameter in my Remote Config (RC) console with the name of the new test (ex. show_pro_button). The default should be false since the test will be off for anyone not in the test set. ...
