kirubakaran··on Open Source Isn't Dead
Yes exactly! I'm so glad I took this route with my startup. We can't bury our heads in the sand and think the vulnerabilities don't exist just because we don't know about them.
kirubakaran··on Ask HN: What Are You Working On? (April 2026)
I'm building https://hyperclast.com/ - "Smart Documents for Teams" ie a self-hostable Notion competitor. And it is much faster! Here is why I'm building it: https://hyperclast.com/about/

Everyone knows that Tim Cook committed to 100% carbon neutrality. But not many know that they're achieving it by releasing Liquid Glass and attaching a dynamo to Steve Jobs' corpse.

Not surprising at all though, considering the "safety first" vs "yolo" approaches, right?
kirubakaran··on Waymo Safety Impact
The self-driving software could detect that the unmaintained car isn't responding correctly to the controls and refuse to drive.

kirubakaran··on Ask HN: What breaks first when your team grows from 10 to 50 people?
Team knowledge is the first thing to succumb to chaos, in my experience. This is the reason I'm building https://hyperclast.com/ When everything you used to take for granted to be in everyone's "L1 cache" is no longer there, things slow down real quick.

kirubakaran··on The changing goalposts of AGI and timelines
""" I resigned from OpenAI. I care deeply about the Robotics team and the work we built together. This wasn’t an easy call. AI has an important role in national security. But surveillance of Americans without judicial oversight and lethal autonomy without human authorization are lines that deserved more deliberation than they got. This was about principle, not people. I have deep respect for Sam and the team, and I’m proud of what we built together. """

A distinction without a difference, as the expression goes

kirubakaran··on Kanchipuram Saris and Thinking Machines
Yeah I shouldn't have posted The Office meme. My bad. Unfortunately it's too late to edit my original comment.
kirubakaran··on Kanchipuram Saris and Thinking Machines
Tamil is my mother tongue and I agree 100%. And like insisting that sentences shouldn't end with a preposition, or "you should say GNU/Linux, not Linux", it's no way to make friends and influence people.

Whenever someone says "actually", it's hard not to think of https://www.youtube.com/watch?v=dGvw-E4OtOA

kirubakaran··on Show HN: Streaming gigabyte medical images from S3 without downloading them
Of course you could commercialize it!

You've already done the "building v1" part, and have started to do the "talking about it" part.

Next step is to write up how one could use it, how it is better than the alternatives, and put it up on a website.

I'm happy to chat about it if you like. My email is in my profile.

Once you have real users, they will pull the v2 out of you, and that will be what you'll sell.

What I've written above sounds like a business proposition, but I want to clarify that I'm just offering to share what I know for free :-)

Thank you so much, I'll improve those points. I agree that a sample workspace would be great. I'm going to work on that today.
kirubakaran··on Show HN: Ferrite – Markdown editor in Rust with native Mermaid diagram rendering
Thanks, I mentioned "fast" to differentiate it from Notion, which becomes super slow as you add more and more pages.

Obsidian and Zed are desktop apps, whereas Hyperclast is web-based. Obsidian isn't multi-player, and not really meant for teams.

Thank you!

> There's a heavy emphasis on performance. Are you sure customers care about that more than real time collaboration and self hosting?

- Good point, I'll find out

> Notion has a feature to export an entire workspace; can you ingest that and get me spun up with your product?

Yes, I'm almost done with this feature

> If I hear something is open source I expect to be able to try it out immediately without logging in. It looks like you can do that but when you hit "Get Started" it puts you into a registration flow.

I link to that elsewhere in the page: https://hyperclast.com/dev/ I'll look into making this more prominent.

> You might take a look at how Zed is marketing themselves

Thanks, will do

> embed the interface in your landing page

Great idea, I'll do that!

Thanks, I'll fix that.
