drchiu··on Ask HN: What are you working on? (September 2026)
Working on a card game website (https://bs.fyi). Currently have a few games popular in Asia, including Big 2, Tiến Lên, and Dou Dizhu.
drchiu··on Ask HN: What are you working on? (September 2026)
Broadcast (https://sendbroadcast.net); been working on this since 2024.

It’s a self hosted email software.

drchiu··on Ask HN: What are you working on? (August 2026)
Working on Broadcast: https://sendbroadcast.net

What it is: Self-hosted email marketing software

Been doing so since 2024 (pre AI coding era).

drchiu··on Shadcn/UI now defaults to Base UI instead of Radix
Just read the post and it didn’t sound AI to me.

Would be kind of funny if someone from the team came out and said it was written by a human.

drchiu··on Apple announces significant price increases for MacBooks, iPads, more
My prediction is that the semiconductor price increases is going to cause a lot of demand destruction. The semiconductor companies revenues is not based on new products but rather on the fact that there is scarcity. Once that scarcity is removed then I suspect that we're going to have some reckoning happening across the industry.

Just bought a MacBook Air that I didn't need to hedge in case my current laptop breaks down. Won't be buying it at the higher price.

drchiu··on Ask HN: What are you working on? (May 2026)
I’ve been working on Broadcast since Sept 2024:

https://sendbroadcast.net

It’s a self-hosted email marketing/newsletter app. The basic idea is: own your subscriber database, run the app on your own server, and send through SES/Postmark/Mailgun/SMTP instead of being locked into another SaaS.

Not trying to be “Mailchimp but cheaper”. It’s more for technical founders, agencies, and consultants who want a boring, controllable email tool they can deploy for themselves or clients.

I’ve kept the changelog public because I wanted the work to be visible: https://sendbroadcast.net/changelog

My buyers are typically people who want to own their data and are in regions that have strict data privacy regulation/laws.

Interesting fact: This was my real last project where v1 was built by hand before AI coding became the norm in the software industry.

drchiu··on I won a championship that doesn't exist
My wife cited ChatGPT as her primary source the other day when she wanted to debate with me on something.

"AI told me that..."

In the old days, it would have been "I read on Google..."

drchiu··on The Sideprocalypse
It was never easy after ~2010.
drchiu··on Ask HN: What are you working on? (February 2026)
Also working on App Shot Editor [1], a free iOS/Google App store screenshot generator. Basically my kids were getting into mobile app development, and I wanted an easy way for them to create the screenshots needed for the app store listing.

I'm working on Checkend [1], which is a self hosted error monitoring app. I needed something lightweight and easy to deploy.

drchiu··on Show HN: Free app store screenshot editor
A lot of folks building iOS apps these days (I wonder why). Heck, my kids decided to build some themselves the past couple of weeks.

When it came time to submitting to the app store, we needed app store screenshots. I didn't want to buy "yet another software".

So, I created this (Disclaimer: with the help of AI).

Enjoy.

drchiu··on Ask HN: What are you working on? (January 2026)
https://sendbroadcast.net - I've been working on it since October 2024, and it's still going strong.

Currently on v1, but working on v2 release in the next month.

drchiu··on Opus 4.5 is not the normal AI agent experience that I have had thus far
Having used Opus 4.5 for the past 5 weeks, I estimate it codes better than 95% of the people I've ever worked with.

And it writes with more clarity too.

The only people who are complaining about "AI slop" are those whose jobs depend on AI to go away (which it won't).

Working on https://stepsies.com

Tagline: Turn your knowledge into interactive guides

Had the domain for 2 years, and finally putting it to use.

drchiu··on Cloudflare Timeouts in Europe
All my European servers proxied through Cloudflare's CDN are down.
drchiu··on Cloudflare Global Network experiencing issues
Just when the eastern cities are waking up too.
drchiu··on Open hardware desktop 3D printing is dead?
Better printers came along, were not "open", but they were easier to use and maintain especially for first-time hobbyists and even for print farms.
drchiu··on Building better AI tools
Friends, we might very well be the last generation of developers who learned how to code.
drchiu··on Ask HN: What are you working on? (May 2025)
I have been working on Broadcast (https://sendbroadcast.net).

It’s an email marketing tool, self-hosted, for use with existing ESPs like Postmark, Mailgun, Amazon SES, etc.

Been working on this since September 2024, and have been consistently hacking away at it weekly: https://sendbroadcast.net/changelog.

drchiu··on People are bad at reporting what they eat. That's a problem for dietary research
Another way to look at it is that tracking what you eat is very difficult. Currently trying to lose a few pounds and doing calorie tracking. Practically carry a scale and a calorie tracking app with me. About once a day there's still some "estimation" involved due to the fact that all the ingredients are mixed together.
drchiu··on Open Source Alternative to Vercel, Netlify and Heroku
I enjoy using Kamal as well. It's simple enough for small teams to understand quickly and flexible enough to tinker down at the server level.
drchiu··on Ask HN: Those making $500/month on side projects in 2024 – Show and tell
Built https://sendbroadcast.net for myself and started selling it too. Made about $1500 usd so far over the past 2 months and a bit.
drchiu··on Sam Altman: Long con was "child's play for me"
To play in SV, you have to study Game of Thrones, Art of War, etc.
drchiu··on Show HN: No-code CLI script builder
Dev for proggy.io here.

Why I built this: I occasionally find the need to build CLI scripts. Whether it be for resetting variables, performing some mundane task, it seemed to involve the same process of trial and error. I wondered if it would be possible to create some sort of reusable blocks and design my CLI program with a web UI. This way, anyone on my team could modify it who weren't comfortable touching bash scripts or just wanted something where they could clone and tinker for their own needs easily.

Be happy to answer any questions!

drchiu··on The loneliness of the low-ranking tennis player
As a parent with kids who play junior tennis, I remind them after every loss (and win) that this is just a hobby.

But the number of parents who take this so seriously would surprise anyone not part of this culture.

The travelling, the hotel rooms, the large number of tournaments played every week -- all these things start early (7-8 years old). School? Forget about it. They're superficially home-schooled. Tennis is all they do, and if they're lucky (at least by the standards of the article), they don't get good enough to be a low-level "pro" and get a chance to go to school for a proper education and get a regular job that pays well.

If they're unlucky, they get a D1 school, on a full-ride scholarship, and then waste a few years of their lives continuuing to damage their bodies in pursuit of "making it" as a pro tennis player.

drchiu··on The economics of American lotteries
Lotteries have asymmetrical risk/payout.

Not crazy, if one could allocate a small amount of money to it.

drchiu··on Children need risk, fear, and excitement in play
Let’s not forget the role of lawyers and the general increasing litigious nature of society.

Things are made “safe” because there is now always a risk of getting sued when stuff happens.

drchiu··on A Canadian payroll dependency chart
A lot of countries trend toward bureaucracy as their biggest “innovation”.

Unfortunately, the same people who are in position to change things for the better (ie. to make a country more competitive, innovative) stands to benefit from more bureaucracy, not less.

drchiu··on Now that cars are like smartphones, we don't really own them
One day, a new car startup will come out offering exclusively analog cars.
drchiu··on AWS IPv4 Estate Now Worth $4.5B
Engineers/designers never assume their ideas aren’t as clever as it appears in their minds.
