If you want to get good at something, document your progress. An inexpensive notebook and one-line entries is fine to start.

Plan for the day: a few hours of AWS study, then doing some exploration in the Java/Springboot ecosystem.

Curious about the intersection between systems programming, scripting, and JavaScript? Join me and Adam Young in Portland, Maine, Tuesday, Nov 10, for a collaborative talk on tools and tradeoffs. www.meetup.com/mainejs/even...

My latest writing about SEO. It's a black box for good reasons. My goal to be on the first page and the search engine's goal of surfacing relevant information are not always in alignment. www.jakeworth.com/posts/black-...

Starting today, direct to your RSS reader, you can get quotes and notes on the most interesting things I'm reading. Shoutout to @jakeworth.com for recommending that I get an RSS feed set up for these. still.visualmode.dev/blogmarks

TIL: ChatGPT reminds me of this the `main()` scripting syntax I'll be using in future JavaScript work. www.jakeworth.com/tils/javascr...

Maine tech folks: join us on Tuesday, October 13 for a JavaScript-themed social at Novare Res! Recent discussions have centered on agentic AI, CSS, type-safety, and more. All experience levels are welcome. www.meetup.com/mainejs/even...

I think whipping up a technical talk in 24 hours and then giving it, and not falling on my face, is a good skill to keep sharp.

Giving a talk tonight on reflective programming in JS! Hoping to get a question or two, because I have a few of my own.

Interested in learning or getting better at JavaScript? It's never been a better time! Please join us tomorrow at the Maine JS Meetup at Portland Webworks. We'll have some good talks, networking, and socializing afterward at Novare Res. www.meetup.com/mainejs/even...

Today's TIL: calling Git hooks on demand. www.jakeworth.com/tils/call-a-...

Linking to a local node module with npm-link: www.jakeworth.com/tils/link-to... #til #javascript

Found a use for TypeScript's tsc --watch today. www.jakeworth.com/tils/tsc-wat...

Experimenting with building a React skeleton UI library today.

Tech folk of Maine! Just over a week until our September Maine JS Meetup! Please RVSP now and join us for a fun evening of JavaScript lightning talks and networking in Portland, Maine. www.meetup.com/mainejs/even...

Today I'm writing a blog post about validating a problem exists before solving it.

On my mind today: if you want an unusual outcome, do unusual things.

Today, did some QA on an app I'm building. One learning: AI is good at generating content, but it benefits from a quick sanity-check before shipping to production.

What's a technical book you've read and would recommend to any programmer?

An important part of engineering is confirming that a problem is a problem, before trying to solve it.

Engineers who are new to TypeScript may find its errors to be cryptic. This post will help you understand them better. www.typenotes.io/notes/why-ty...

Migrating to TypeScript is less about the technical details and more about picking a place to start. A technique that I've seen work well is to pick a seam: utility code. www.typenotes.io/notes/migrat...

In JavaScript, double equals is bad and triple equals is good, right? I'm breaking down the difference here: www.typenotes.io/notes/javasc...

Generics are a TypeScript feature that some find confusing. Don't be confused anymore! The best way I know of to understand them is a concept from functional programming: identity. www.typenotes.io/notes/typesc... #TypeScript

The TypeScript handbook suggests these are equivalent: let state: string = 'maine' let state = 'maine' Have you ever wondered how you could prove that's true? A brief exploration of contextual typing: www.typenotes.io/notes/inspec... #TypeScript

TSX is a tool I've been using in daily TypeScript exploration: $ npx tsx Install and run this program, and you'll enter a #TypeScript REPL! You'll need some additional techniques to get type-checking, though. My summary here: www.typenotes.io/notes/runnin...

“Be conservative in what you do, be liberal in what you accept from others.” Primary keys from an API are a great opportunity to practice this principle. #TypeScript www.typenotes.io/notes/typing...

I often want the same #TypeScript string list in three places: runtime values, a state type, and function parameters. Duplicating a union by hand drifts out of sync quickly. Here's a solution I've found: `as const` combined with an indexed access type. www.typenotes.io/notes/union-...

Are you looking to get better at TypeScript / JavaScript, in small daily doses? 🚀 I'm building TypeNotes to take the real-world lessons I'm learning every day building TypeScript apps and distill them into short actionable tips and tricks. #TypeScript www.typenotes.io

Relative imports in #TypeScript can be useful. This relative import tells me these two files are located in same dir and meaningful to each other. More on this and my preferred alternative, path aliases, here: www.typenotes.io/notes/path-a...

Just finished "How to Open Source" by @schneems.bsky.social. Fantastic! Gave me the push to comment on an open issue. github.com/lodash/lodas... howtoopensource.dev

A small thing that's worked well for me in code reviews: commenting and approving at the same time when nothing is blocking. www.jakeworth.com/posts/on-com...

I’m thinking about a weekly newsletter for SaaS CTOs (teams ~10–100 engineers): “3 tech trends you should care about (and what to do about them)” Format: - Act on this - Watch this - Ignore this Would you read that? If yes, reply or like this post, and I’ll send a first issue to a small group.

This is an enviable quality of great software engineers I've observed. If you're trying to level up, it might help. www.jakeworth.com/posts/gettin...
