Working on Humadroid - trying to make SOC2/ISO27001 compliance less painful for small businesses. The $30-50K consultant route is brutal for startups, so we're building an AI-assisted platform that helps with policy generation and guidance. Still in beta and learning a lot from each customer we onboard. We're actually going through our own SOC2 assessment in August, which has been... educational. Recently added busin…

Love this! Not a customer but could see it happening. ISO 27001 compliance (or equivalent) is a standard requirement when working with the public sector in my area. NIS2 is also on the horizon, have you looked into it?

Thanks! Really appreciate the interest. We already support a major part of ISO 27001 - actually releasing our Statement of Applicability tomorrow or the day after. I went through ISO certification at my previous company, and that experience is what triggered building Humadroid in the first place. The pain was real! NIS2 is definitely on our radar - planning to have support for it by Q4 2025. The public sector requirements you mentioned are exactly the kind of use cases we're building for.

After 15 years doing mobile apps, security, and systems development. I ended up learning ton about Cloudflare.

Now connecting all the dots and building a backend for mobile apps. It’s already live https://calljmp.com

Fully powered by Cloudflare, unbeatable pricing, rls and app attestation, raw SQLite queries, and tons more.

Looking for early feedback and adaptors.

My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and grind them in its propellers. Our target platform is a 40 grams tinywhoop so it’s safe to fly everywhere and makes almost no noise :). A Roomba for mosquitoes! The main plus compared to traditional systems is that a drone can cover an enormous…

Hadn't seen this before, this is awesome! I lived in Cameroon and Kenya briefly doing some consulting work and mosquitos still wreak havoc across the continent (and now living in DC I wouldn't mind having one of these in the summer for my place). I'm curious if you're also thinking about defense applications -- I would imagine that a super low cost drone that could help take out a shahed or other Russian drone that a…

A 40-gram device is unlikely to pack any punch, except against a mosquito.

It could be a great reconnaissance tool though.

I'm working on a Heroku / Render / Flyio alternative thats free, open source, built on top of Kubernetes. Supports deployments of your own apps as well as 15k+ other packages (postgres, airbyte, dagster, etc) via helm charts. https://github.com/czhu12/canine https://canine.sh Reason? Got sick of paying for the massive markups on PaaS but missed the simplicity and convenience.

Gieeve an instantly deploying AppEngine Standard, please. It's still great and the integrated push queues rather valuable, but Google likes to make the rest sooo complicated...

I am building Tracelake - a data quality solution for SAP replications.

https://tracelake.com/

Why? SAP holds the most important data for companies that use it, but it's notoriously difficult to replicate this data consistently into a data analytics platform (think Snowflake, Redshift, etc...).

Couple of companies specialize in the SAP replication, but it's hard to validate the correctness of the replicated data, because:

- the SAP data is changing continuously and rapidly

- there are hundreds of tables and TBs of data

Usually it's the consumers of data downstream who notice that the data just "doesn't feel right".

Tracelake adds a validation layer on top of the SAP to X replication, which periodically compares the data between source and target and informs you about any missing / incorrect data, so you can tackle data quality issues proactively.

Working on fabric construction blocks (like Lego of clothing), that you can use to build clothing and accessories completely by hand without any tools or machines. Intro video: https://www.youtube.com/watch?v=X_eKc6c5tDw

This is insanely amazing. The youtube video is so well-created. I hope to see this become successful!

Optimizing the Marginalia Search index code. The new code is at least twice as fast in benchmarks, but I can't run it in production because it turns out when you do it's four times as slow as what came before it for the queries that are the simplest and fastest to the point where queries exceed their timeout values by a lot. I'm 97% certain this is because the faster code leads to more page thrashing in the mmap-base…

It's annoying because it's right and also describes the exact type of paradoxical performance reversal I'm seeing. (It's also great because it describes the exact type of paradoxical performance reversal I'm seeing, likely saves me a lot lot of head scratching ;-)
