My Corsair Scimitar mouse started acting up this week so I had to completely deconstruct it to clean out two small cats worth of fur from around the scroll wheel. During my internet travels related to this procedure, I came across the acronym DPI, or dots per inch, that many mouses use to quantify their sensitivity. A low dots per inch value (ex. 800) results in slower, more precise cursor movements when the mouse moves in the physical world. A higher value obviously means the opposite - your cursor zings across the screen when the mouse is nudged one way or another. You can typically adjust this value using your mouse’s software provider and/or by using the mouse settings on your computer. ...

There is a static method in JavaScript called Promise.race() which “takes an iterable of promises as input and returns a single Promise that resolves with the first promise that settles”. This provides an easy way to set maximum timeouts on your functions: const timeoutPromise = new Promise<boolean>((resolve) => { setTimeout(() => { console.log("EOU detection timed out after", TIMEOUT_MS, "ms"); resolve(true); }, TIMEOUT_MS); }); const detectionPromise = (async () => { ... }); return Promise.race([timeoutPromise, detectionPromise]);

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. This week, I finally decided to see what else was possible and it turns out you can replace the current window with the new one by appending the -r flag to the command: ...

You can tell TypeScript to treat a string value as a literal type using the as const phrase. For example, if you have an interface like this: export interface Message { role: "user" | "assistant" | "tool"; content: string; } You can add objects to it like this: const updatedMessages: Message[] = [ ...currentMessages, { role: "assistant", content: baseResponse, }, ...(functionResponse ? [{ role: "assistant" as const, content: functionResponse }] : []), ];

Adding scripts to your package.json file is an efficiency necessity, but what makes these scripts even more effective is the ability to pass arguments to them while still using the abbreviated npm run {command} format. 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.
