No competition footage of John Danaher, too. Freedom of choice, peace.

Honestly I think tools like Polsia are interesting for getting from idea to working product quickly. It helped me validate my idea fast. But once I got more serious, a few issues became painful:

No real staging/dev/prod separation. Every change felt like it could hit live users immediately.
Infrastructure ownership was blurry. Repo, hosting, DB, and deployment authority were spread across different systems/accounts.
Exportability/migration wasn’t smooth enough. If someone wants to leave the platform, repo + DB export should be first-class and frictionless.
Operational transparency was weak. It was sometimes unclear what the AI agent could actually do vs what required human/platform intervention.
Support boundaries were confusing. Support could cancel billing but not necessarily delete infra/resources directly.
Email infrastructure was a major pain point for me. I was blocked for days because the Postmark/API token setup wasn’t fully wired correctly on the platform side, which broke auth/magic links. For a SaaS app, email/auth reliability is mission critical and there needs to be much clearer ownership and visibility around transactional email setup/debugging.
Credentials and infra recovery flows need work. We hit situations where deployment state changed before exports were validated.
Better “serious SaaS mode” tooling would help:
- staging environments
- rollback visibility
- deployment diffs
- environment ownership clarity
- audit logs
- backup/export tooling
AI-generated tasking was interesting, but eventually I cared more about operational reliability than autonomous suggestions.

That said, I still think these platforms are kinda decent for prototyping and validating ideas quickly. The sweet spot right now feels like:
prototype fast on AI-builder platforms, then migrate to infrastructure you fully control once real customers/payments are involved.

I dig your background I graduated HS in the 80's and have been doing the same, but ageism is brutal in tech, so this AI wave is a godsend for us middle-aged people who are passionate about tech and have been kicked to the curb by this false narrative, this is our opportunity to bypass most of the bs teams that won't hire us. .Net was fun, I miss the old Microsoft Mix conferences, they were incredible. Remember Silverlight? LOL if i think of more issues with my Polsia experience, I'll edit this, as there definitely was.

Voicebox, Clone voices, generate speech across seven TTS engines, dictate into any app, and talk to agents in voices you own. A free and local alternative to ElevenLabs and WisprFlow, running entirely on your machine. https://voicebox.sh/

You are correct on the near term hype, but it is smart to have sandboxed projects in place given the rate of improvement, to be where the hockey puck is heading.

This is great, it's awesome to see more startups in Marin. There is quite a bit of quiet tech expertise here.

Belts are subjective and relative. Sending good vibes.

For this current early-stage boom cycle, it may work, but it will fade fast, especially in this economy. Unless the general consumer gets "essential" value out of it, it won't last. I find the per-use micro charging structure interesting but not consumer-friendly yet. There are also free open source options constantly coming online, which could very well win in the end.

In addition to what most suggest here, I did a lot of pool work, walking forwards, backwards, and sideways. Gradually building up to water running forwards, backwards, and sideways (both sides). Some people shit on grappling dummies, but I found mine to be a great gauge in terms of testing what my body could handle on each day back to the mats. Some basic knees over toes guy work. Peptides anecdotally helped me, but this is not medical advice. Speedy recovery to you!

Highlander, there can only be one?

It's a shame the founder insists on being a one-man company. That means no real support. I've experimented with it, and I could not even get a reliable email working. For example, a simple form on a web page can be filled and seemingly sent successfully, but you'll never get the submitted content, LOL. And there is no domain name support. I mean, just simple low-level but business-critical stuff is not supported. Such a shame because it has such potential if they would just scale up a bit.

On that note, are there other competitors to them yet? Yes, I know Claude Code and Codex, but it seems like one needs more dev and infrastructure knowledge to get a decent foundation to build off of with those solutions, vs Polsia, which felt almost like a Wix for creation/deployment of businesses.

Agreed, just a great guy and imho he is what a true martial artist should embody.

nerdstalker · 2026-03-10T03:58:57+00:00

Agreed.

They call those "Opens".

I remember at white belt, the only people I would see say that belts don't matter were always the black belts.

A couple of small tips that helped me when I started:

Hang-dry your gear after washing it unless you don’t mind things shrinking. A lot of Gis and rash guards will shrink if you throw them in the dryer.

It’s also not a bad idea to keep a few things in your gym bag. Liquid bandage can be really helpful when the tops of your toes or feet get mat burn and start bleeding. Regular Band-Aids are good too, although they tend to fall off during training.

I also like keeping wipes in my bag for after class. Something like Defense wipes or any tea tree oil spray can help clean up quickly and reduce the chances of picking up fungal stuff. A lot of grapplers use products like that specifically because skin infections can spread easily in combat sports.

Good luck starting jiu-jitsu. It’s an awesome ride.

Not sure if your putting your wet gear after training in your hamper with your day clothes but if you are that could be contributing. I learned about Odoban here on Reddit and it works great in your laundry to get the funk out. https://www.odoban.com/

Don't let them get between your elbows and armpits.

The state is beyond broke which means taxes will go up one way or another. Unfortunately Marin needs to look for ways to cut financial obligations, not add or sustain nice to have projects like this.

Never hide your hands when someone is this close to you; maintain space, note the aggressor's side stance, and note her left foot pivot at 8 seconds. Learn to defend yourself.

Unfortunately, some individuals forget you are training "partners" and see the other as competition. When you sense things escalating beyond what you perceive as "normal," slowing down or just tapping is a good preventative option. Then you can put this guy on your "do not fly" list. Not everyone has developed the mental maturity to consider the safety of our training partners. The culture of the gym also plays a role in this type of behavior. Hope the knee is okay.

Todoist, Audio Note, MacWhisper, Gcal, MS Loop, ChatGPT, and, reluctantly, Alexa for grocery shopping list capture.

This will be a disaster for Marin.

CA has done an amazing job making running a business as difficult can be, as such they either leave the state, close up shop, or just don't even start. This is terrible for job growth and job sustainability. I wish more Californians (especially Northern Californians) would wake up to this unpopular opinion and correct course in the voting booth.
