vital101··on Ask HN: What are you working on? (September 2025)
I've been fiddling with a long-term niche product for WordPress plugin and theme updates. It's 10(!) years old this year. Working in a code base that old 100% of my own commits is both amazing and terrifying. Past me was not as experienced at current me :)

vital101··on FreeBSD on the Raspberry Pi
Are there any Raspberry Pi competitors that people like? I've see a few referenced in different articles but I don't have any idea how reliable or useful they are.
vital101··on Ask HN: Who is hiring? (October 2022)
I don't see the "Engineering Director, Frontend" position on the hiring site. Is it still available?
vital101··on Java Development on an Apple M1 – A One Year Review
This is similar to how developing with VSCode is on Windows + WSL.
vital101··on Simulation of a 2B-atom cell that metabolizes and grows like a living cell
The article mentions that they use minimal cells. "Minimal cells are simpler than naturally occurring ones, making them easier to recreate digitally."
vital101··on How to Run Wordpress on AWS
I personally wouldn't build my own infrastructure. I'd use something like https://convesio.com/ and let them handle the scaling.
vital101··on Using VueJS Alongside Django
I've been using Django with Vue sprinkled in on https://candid.work and it's been a pleasure. Using Vue for reactive stuff and then modifying form fields after the changes so Django can still do the updates has been a pretty great experience so far.
vital101··on Ask HN: What is your passive income 2019?
Kernl (https://kernl.us) - WordPress Plugin/Theme Updates, Git Deployment, Analytics, Load Testing, etc.

Currently around $1200/month with fairly linear growth. It's a fun project to work on and I get to make money on the side for doing it.

vital101··on Slack S-1
Zero to IPO in five years. Well done team Slack!
vital101··on Ask HN: One-person SaaS apps that are profitable?
I made https://kernl.us solo and it's making ~$1100 MRR and growing.
vital101··on Ask HN: What discontinued company/product do you wish was still around?
It isn't quite the same, but I've had great luck with a combination of VS Live Share (https://marketplace.visualstudio.com/items?itemName=MS-vsliv...) and then Zoom or some other tool for voice communication.
vital101··on FrontPage 98: Elegant and Exquisite (1997)
Back when I was in middle school I used a copy FrontPage 98 at school to generate frames for my Star Wars site and then finished up the rest at home with FrontPage Express. A few years ago I restored the site after finding a broken version of it on the WayBack machine.

vital101··on Ask HN: Those making $500+/month on side projects in 2017 – Show and tell
I've been working on https://kernl.us for a little over 2 years now.

It's currently making $650 / month and growing.

Something I "knew" but never really understood about growing a business is how long it can take. Granted this is completely on the side, but it still takes a long time to find your market, grow, get customers, etc. Learning that this is actually a marathon was valuable.

The other thing I have to actively manage is building things that are valuable -vs- things that I find interesting. As a developer I LOVE tinkering with new technology, but when I'm wearing my business hat upgrading to the new hot frontend framework doesn't make that much sense.

vital101··on Ask HN: What was your best passive income in 2016?
Many years ago when I was still a PHP + Wordpress developer, I discovered that getting updates to private plugins and themes was a huge pain.

Fast-forward a few years and I finally built out https://kernl.us as a learning project (Mongo, Node.js, Angular). It's mostly passive income now, pulling in ~$450 per month.

vital101··on Ask HN: Single Person startup/company?
I started https://kernl.us last May and brought it out of beta in January. I've been growing at the rate of around 5 new paying customers a month.

After the closed beta I started out with about $140 / month in profits, which has grown to $330 / month over time. The growth rate has been pretty steady, but nothing so large that I could go full time on it.

vital101··on Ask HN: Passive Income Suggestions 2016
I build a developer tool for premium plugin / theme authors in the Wordpress ecosystem. If you can build something that scratches an itch in a programming ecosystem, people are likely to pay for it.

Although with the amount of work I do on it, I'm not sure I'd call it passive ;)

vital101··on Free Transactional Email Services – The Best Alternatives to Mandrill and Co
I just finished the work today of migrating from Mandrill to SendGrid. I can't speak for the other providers, but so far it has been a fairly painless process. The client libraries for Node are similar enough between the two that I didn't have to put a ton of thought into refactoring.
vital101··on Ask HN: What are you working on and why is it awesome? Please include URL
Private Wordpress Plugin & Theme updates + CI services - https://kernl.us

It's awesome because I get to work on fun technologies (MEAN stack), learn how to scale Node.js, and interact with a great community. Also, I have paying customers which makes it even better :)

vital101··on Ask HN: Out of beta with paying customers. What's next?
Thats a good point. If I can differentiate the plans more, charging more becomes a lot easier. +1 to grandfathering existing users.
vital101··on Ask HN: Out of beta with paying customers. What's next?
Yes, thats correct. I initially priced this based on what others in the industry were pricing. I think eventually I'll experiment with pricing a little bit, but I'm worried that with higher prices developers will just say "Meh, I can implement this myself" and go the other direction.
vital101··on Ask HN: Out of beta with paying customers. What's next?
Thanks for the response (and critique). I think you're probably right. Unless this can target a much larger part of the Wordpress development community, it probably won't attract VCs.
vital101··on Ask HN: What are you currently building?
We make it pretty easy to do with Kernl. It also supports "push to build" from GitHub or BitBucket if that interests you. If you have any questions send me an email: jack at kernl dot us
vital101··on Ask HN: What are you currently building?
I started working on getting my private Wordpress plugin and theme update service out of beta. It's getting closer! Maybe by the end of the month.

https://kernl.us - Come check us out!

vital101··on Ask HN: Product Pricing
Thanks for the reply. You make good points. I imagine I'll end up doing a lot of A/B testing on pricing to see what sticks the best.
vital101··on Ask HN: What project are you currently working on?
I'm working on private hosted Wordpress plugin and theme updates. My goal is to do for Wordpress updates what Github did for Git.

Its currently in a private alpha, but I've already got 26 users signed up! I have lots of ideas for doing automated builds, webhooks, and third party integrations, but the going is slow because I lack a lot of time to work on it.

vital101··on The Inferno Operating System (1997)
Back in grad school we used the Inferno OS as a learning tool. I don't remember too much about it, but I do remember using Limbo (precursor to Golang) and liking it quite a lot. When Go came out it was really easy to pick up due to my time mucking around Inferno using Limbo.
vital101··on Ask HN: How many users is 'enough' for an Alpha?
Congrats on 800 sign ups, thats huge! I agree with you on aggressively tracking metrics, although I think I need a bit more than 20 users for my alpha. Its nice to have a concrete number to compare against, even if we aren't in related niches.
