czhu12··on We're working on a new RuneScape MMO
Runescape was the first thing that got me into coding. Fell in love with the game and had a ton of admiration for the devs who could spend decades crafting the same game, to create such a wonderful playground for so many millions of people.

Stopped playing after a few years but still have many fond memories of the joy I had everyday after school logging onto that game.

czhu12··on Sonnet 5.5
The other thing too is that I’m having a hard time reviewing these massive PRs that are being generated. So much so that I’m having it write me a book (also vibe coded) that I can read through to learn about all the stuff it did as part of the pr review https://ai-lessons.oncanine.run/
czhu12··on Tells of a Slop UI
Yeah brutalist is exactly right, that is basically what I prompted for. I didn't realize a bunch of other people were doing this. Actually the only inspiration I had for this was watching the movie (Brutalist) a few years back.
czhu12··on Tells of a Slop UI
You could be right, I haven't seen too many like this yet, but it did some out with this staggeringly fast. The style I've seen the most are the gradients + font changes mentioned in the article.
czhu12··on Tells of a Slop UI
At least some of these are just for lack of caring. I vibe coded this landing page recently https://tui2web.com/ and fought off a lot of the defaults the LLM came up with after a few hours of iteration. Feel free to roast it, I'm not really attached, but I thought it did a reasonably good job.
czhu12··on Does Georgism work? Five years later
Just dropping by to say that you're doing gods work advocating for more housing. Its exhausting seeing amount of cynicism around how the status quo just can't be changed for this or that reason, but seeing the small, incremental, advocacy over decades pro housing groups put in is really inspiring. An incredible amount of progress has been made here
czhu12··on Bill to Ban Private Equity from Owning Medical Practices
The economist did a piece in defense of private equity a few months ago. Basically boils down to more efficient resource allocation across an entire economy, deep pools of capital to rapidly transform businesses into things people want to buy from.

czhu12··on Minimal Phone 2
I find for these what happens is that the phone itself can’t actually install certain banking or security apps, and also our workplace restricts it.

Inevitably I have to carry two phones around Anyone find a solution around this?

czhu12··on An empirical study of harness design for coding agents
I think they are referring to the file https://github.com/SWE-agent/mini-swe-agent/blob/main/src/mi...

190 lines with comments included so close enough

Which is the actual agent? Everything else is just glue code to connect to different LLM providers, etc

czhu12··on Ask HN: What are you working on? (September 2026)
I've been slowly working on https://github.com/CanineHQ/canine for about 2 years now. Basically a self hosted, FOSS that turns a Kubernetes cluster into something as easy to use as Heroku. Its grown to about 2000 active developers using it host small things at https://canine.sh

It was a pain point from a start up I cofounded before where we needed Kubernetes flexibility but developers hated using it. I figured there was no reason why it had to be hard to use and thus Canine was born.

Lately been playing around with setting up remote dev containers on your own compute as well -- basically like github codespaces, except self hosted.

Built in Rails + Stimulus

czhu12··on >10x More Efficient Pretraining
"Almost nobody is using fable 5" at anthropic apparently

czhu12··on Compute-efficient pretraining and scaling to trillion-parameter models
its already true today according to openrouter usage stats. https://openrouter.ai/rankings Most people just use cheaper open weight

czhu12··on Doomscrolling ourselves to death
One thing that recently clicked for me was making podcasts for my girlfriend / friends / parents on the subject, highlights of books I’ve read. It’s like a virtual book club.

Somehow even though this adds a gigantic amount of burden to reading, it taps into a “productivity” seeking part of my brain that can then create a sense of focus and accomplishment after each book.

Since then reading has been a lot easier and I can usually get to 1 hour per day. Still really underwhelming but it’s way more than I managed to accomplish through sheer force of will in the past

czhu12··on OTel isn’t going well
It really never grokked with me why there isn't just "open source Datadog" that can be installed and used. End to end, stateful, that we can just self host.

Our team tried to set up open telemetry to replace Datadog and got totally crushed in complexity. The model of having Open Telemetry just be for standardizing & exporting to other backends, needing glue for each part of the setup was nuts.

czhu12··on Taxi drivers rarely die of Alzheimer's
I had to read this a few times to make sure I read it right

> After adjusting for age, sex, race, ethnicity and education, roughly 1 in 100 taxi and ambulance drivers died of Alzheimer’s, compared with 1 in 60 people overall

I would’ve thought the effects were more profound

czhu12··on Ask HN: What Are You Working On? (July 2026)
1000% agree, the goal of canine is to make it so that you don't have to think about the guts of the system until you want to. Inevitably, companies outgrow the custom-built, closed-sourced, vendor-hosted platforms, but Canine allows you to fall back to Kubernetes.

The thing that inspired me was realizing that all of the current platforms that make it easy to host apps today are built on top of Kubernetes anyways -- they just hide it all from you. I'm hoping Canine gives people an option to self host on their own Kubernetes, and with sensible defaults, get basically as easy to use of an experience.

czhu12··on Ask HN: What Are You Working On? (July 2026)
Been working on an open source, free, Heroku alternative at https://canine.sh for about two years. Its basically a one-click install against a Kubernetes instance to give you a Heroku interface.

I feel like even after all these years we’re still missing the devex that Heroku provided.

Canine basically wraps a Kubernetes cluster -- gives you a heroku like interface to deploy applications to. At some point, if you get big enough that canine is no longer powerful enough, you can just "eject" canine from kubernetes, and continue using kubernetes directly, without having to do any migrations.

Just passed about 2000 developers, at this point most of my work is resolving bug fixes, adding helper text everywhere to make things cleaner, and supporting setups I've never encountered like homelabs with changing IP's

czhu12··on Grok 4.5
Its remarkable how Anthropic is able to maintain their edge against all competition. Anyone have any idea what the secret sauce is that has Anthropic at the top of all leaderboards for the past few years?
czhu12··on What job interviews taught me about Kubernetes
I built canine.sh for exactly that reason, gives you a sensible deployment platform on top of k8s with one install, and you can customize it once you outgrow it.

czhu12··on AI is slowing down
Code generation isn't big enough of a market?
czhu12··on Ask HN: What are tools you have made for yourself since the advent of AI?
Built this little tool for editing audio with text https://edit-with-text.oncanine.run/

(Transcribes the audio, marks the timestamps, so you can delete a word in the transcript, and it’ll crop out that segment in the audio)

czhu12··on SpaceX, Other Mega IPOs Denied Fast Index Entry by S&P
It seems the general consensus on HN is that they are overvalued and for sure will collapse in value down the road, I could imagine some frustration down the road if these companies actually become, say, 4T by the time they get added to indices.
czhu12··on SpaceX, Other Mega IPOs Denied Fast Index Entry by S&P
This does seem sensible and I’m glad most of my holdings are in s&p funds.

Just to play devils advocate though, what are the downsides of not having 3 of the biggest 10 in the world not in your fund, if you hold to track broad market performance? Wouldn’t that have a massive blind spot on AI related growth?

Whether or not I personally think ai is over hyped or not, the whole point of these ETFs is to make sure I don’t get a say in the matter, since I’m a terrible stock picker

czhu12··on Chuwi Minibook X
I feel like what I really want is a phone that can do this. I've been trying to figure out a reasonable workflow with a tiny mouse, an expandable keyboard, and a phone with termius (SSH Client) + a remote devserver. It's so close, the only issue is the screen is a tad bit too small to get anything real done other than ad hoc vibe coding.
czhu12··on The dead economy theory
This article describes a vicious cycle:

Layoff of workers -> Workers stop spending -> businesses suffer

This is not a foregone conclusion. Laid off workers could find other jobs, with higher incomes, due to productivity increases from AI.

This narrative falls into the trap of zero sum thinking, taken at the limit, you can advocate for jobs programs and helicopter money where people get paid to do nothing to keep the economy humming.

czhu12··on Uber, Lyft drivers in Massachusetts form first US ride-share union
it’s very confusing why uber makes so little profit given hire big their cut of every ride seemingly is.
czhu12··on The bootstrapper's EU stack for under €10 per month
We've been building canine.sh free and open source for an enterprise ready deployment platform.

Think about it like coolify is to a VPS as Canine is to Kubernetes.

czhu12··on Why Japanese companies do so many different things
The Japanese economy is also famous for a macro economic stagnation for almost 40 years, a mild deflationary spiral, and companies hoarding cash on balance sheets rather than return it or invest it.

There are definitely world class companies in Japan, but also broad systemic problems with incentives
