want to learn more about how state updates work, when React re-renders a component, and how closures can affect values inside hooks? I highly recommend BigFrontendDev

After watching Instagram reels of people’s projects, I realized Im not using my free will and coding to its potential. Someone created a fish tank and you can feed it by pinching your fingers My next project will be….

I've been having trouble attaching screen recordings to GitHub tickets because the file sizes are too large. What are some alternative ways to share videos in a ticket?

Who else 'git pull' before working on their branch daily?

I started to time myself doing algos and here's what I noticed: 1) no second guessing 2) forces me to recognize pattern faster I livestream on Thursdays around 3pm PST. Come hang out then so we can do some algos, projects, etc, together.

Which Chrome extension do you guys use to check contrast on page to see if it fits WCAG requirements? #chrome #accessibility

I'm used to writing my sliding windows algo pictured on the left side, but today, I learned how to write it like the right side Personally, the left side is more clean to read and there's no slicing involved What are your thoughts on this?

I found a way to search for files more efficiently. Instead of using VS Code's built-in search, I've been using grep (global regular expression print) to find .tsx files containing specific text: i.e.: grep -r "yAxisScaleType" --include="*.tsx" -l How do you search for files?

New sourdough flavor getting baked

On today's episode of is it just my computer or is it an internet thing? I wasn't getting the print preview to work on Safari on my localhost so I benchmarked it Google's website and it worked. So it is my computer's problem lol :)

Building out my Milestones section where a user can redeem rewards It's getting cuteee

The thing no one tells you about starting a sourdough starter is youre constantly baking My first loaf and got another one coming

Inspired by @racheljychen's RacheLLM, I wanted to add an LLM to my portfolio website so others can ask questions about my bio, projects, tech stack, and how to contact me. Next stop is to add in markdown-style links to render links as clickable HTML

Friends, where have I been? We no longer need a tailwind.config.js file?!! and everything can be done in globals.css file? I love this udpate @tailwindcss.com

I’m currently working through tickets and instead of just "fixing bugs," I’ve been documenting the entire journey from the initial "where does this even live?" to shipping solutions. I’m sharing my full thought process and technical takeaways on my blog.

Starting out my new project by identifying types I will be using throughout the project. How do you like to start out your project?

Starting a new project and I loveeee NPM. Unfortunately, it seems we might have to part ways since PNPM has more advantage of speed, security and so much more.

Learning union-find algo this morning and there's two parts to optimize: 1) compress path in the find function 2) incorporate sizes into union function slowly digesting this algo....so more to comee

This worked beautifully on Chrome, but on Safari, it was a different story. After some googling, I hread that Safari has stricter security controls while Chrome prioritize developer experience and is generally permissive about JavaScript triggering browser dialogs like print 💡

While working on a ticket to enable PDF form printing on the webpage, I came across a simple but powerful trick. Create a button that calls window.print(), which will instantly open the browser’s print dialog, letting users print or save the whole page as a PDF. Pretty cool, right? :)

After fixing an issue on Chrome and getting it to work, I remember I also have to test this code on Safari as well How often do you test cross-browsers?

Wow! @inkeep is pretty good at this! When users ask the AI support chat something the docs don't cover, it automatically opens a GitHub PR to fix the gap instantly. That's pretty cool

Listening in on @roxyrodbeck.bsky.social presentation explaining how she created a worldwide solution with her tube Amazed she built a tube tracker app with vanilla JS for her first round and created a solution to calculate g-tube feed rates

It's one of those days where I have to visually draw out and understand step by step what needs to occur for an algo. The algo I'm working on is generate all possible groceries from a grocery list based on how much money you have

Handling a ticket where a user stated they weren't able to use keyboard navigation on the docs webpage. Putting on my detective hat to investigate the main source to find the suspect

working on padding ('inside' of a border) and margin ('outside of a border') and listening to @dthompsondev.bsky.social 's talk Congrats on your new job btw!

My weaknessssssss Everything was so goooddd

Yes. This book by Rob Eastaway teaches you how to do complex maths with nothing but the back of an envelope, a pencil and some good old-fashioned brain power.

Sometimes when I'm researching about a question I have, a new question popped up. Learning something new sometimes feels like opening a door… only to find a hallway full of more doors 😄 Anyone else like this?

Couldn't find Dev Tools in Safari. Turns out I never activated it in the Advanced Settings under 'Show features for web developers'. 😅

I've been testing my DSA skills to know where I stand. I will chose a random algo (max: medium level) and see if I can solve it within 25-30 minutes. If I'm not able to solve it, I will go back and review the topic again What have you been doing to test your algo skills?

When the customer attaches a Loom recording of the bug they reported

I was unsure if the Docker containers were done spinning up, but I realized I can run docker ps -a to see the status of the containers and confirm they’re actually done running.

Trying to flatten out a 2D list to a 1D list and was thinking of using flatten method (but that's a JS method) 😅 I learned you could use .extend. It takes in a list and adds each item from the list.

The vibes this weekend

The way to anyone’s heart on Valentine’s Day is sushi + donuts. Taking requests now for more relationship advice ;)

🚀 Build faster with Junie CLI. We used Junie CLI to generate a one-tap flying game straight from the terminal – then had Junie review the PR and run a security audit. Join the waitlist 👉 jb.gg/krjcli

Starting on an open source project and was unsure of what commands were used to start the project, so I navigated towards package.json. I'm used to updating commands in my own projects in this file, such as for testing, running dev environment, and so much more

Its aliveeee

As I see more tickets, I learned something new everyday. Today, I learned browser extensions can modify the DOM and React won't know about changes.
