Read about what I’ve been up to @engineering! It started as a random experiment when I was fed up with our current tooling, and it's now a product that’s used across the company.

Thanks to my team, I learned so much about launching a product, driving adoption, and how to make a delightful user experience that competes with existing open-source tools.

we have google maps at home--

fun experiment on rendering pretty maps in the terminal with rust and mapbox/openstreetmap tiles!

What they mean by guerilla marketing

[Henry Nguyen @henryng__]

@freemanjiangg Congrats on launching!!

[Henry Nguyen @henryng__]

@freemanjiangg Looks slick!

[Henry Nguyen @henryng__]

@Shahanneda Yeah it parses the code into a tree and lets you copy whole subtrees

[Henry Nguyen @henryng__]

I spend way too much time selecting code to copy, so I made something to copy code trees faster

[Henry Nguyen @henryng__]

@sohambasu963 Yep! Perfect copying :)

@Parisa__Rashidi It's a custom UI library using webgl

Network Map of 50,000 blogs
I scraped my favourite blogs and made a graph of which ones linked to each other! You can see clusters of blogs that correspond to topics--there's clusters for Canada, rationality, crypto, India, and even postgres.

Did this with webgl and ran into some hard problems with this one:
- rendering 600k antialiased lines of different color / width
- when and where to show URL labels aesthetically
- the "fly to" animation when you search for a domain (inspired by mapbox!)

Might do a blog post on some of these later!

@sincethestudy Should be on the chrome extensions store soon

[Henry Nguyen @henryng__]

@Shahanneda @engineering Yeah pretty much haha. There is some talk about open sourcing 👀--it'd be cool if I could use it in my future jobs.

@Shahanneda absolutely zero--if you can pack a lot of lines and circles into a compact format, then the webgl can handle it pretty well. I'm doing lots of LOD for the text though because rendering text is very expensive.

Check it out at https://t.co/OQoY4n2uut

The data was scraped from all the blogs at https://t.co/ptbHyqvYiG

@aarnphm Maybe because Chrome is the only supported browser on X laptops 😭

[Henry Nguyen @henryng__]

@omkizzy damn i'm so curious, what's the project?

[Henry Nguyen @henryng__]

@amirbolous I've been using this one liner to dump files into a single file I can paste to claude.

find . -type f \( -name "*.ts" -o -name "*.tsx" \) -exec bash -c 'echo "--- < file $1 > ---"; cat "$1"; echo' _ {} \; > output.txt

Also check out https://t.co/5lZ0Dsq6Og if you haven't. It's a travel time map for public transit.

Just added transfer costs so you can adjust how much you hate transferring buses.

[Henry Nguyen @henryng__]

Made a bicycle routing map where you can choose how much you want to avoid hills or avoid cars.

Try it at https://t.co/lyWKrMBCnT

I used Claude to optimize the memory usage so the routing now works across all of California! Made with @Mapbox , @rustlang , and a whole lot of GPT

[Henry Nguyen @henryng__]

@omkizzy @Mapbox @rustlang maybe a safety tolerance--we'll decide to route you through the tenderloin or not :)

I think changing the scoring to add "resting" periods in between long uphill segments would also be cool.
