drchaim··on Claude Fable is relentlessly proactive
Be careful of storing production ssh keys in your laptop, it will find a way to find them :/
drchaim··on Anthropic requires 30 day data retention for Fable and Mythos
Not the case for me. I tried .envs, ansible-vault and sops, and it always ends up reading the unencrypted ones for some reason, usually in debugging sessions, it finds a way to read them.
drchaim··on Raspberry Pi 5 – 16GB RAM
i would say my first Pi was about 50$, crazy times
drchaim··on Anthropic requires 30 day data retention for Fable and Mythos
and all their keys, because sooner or later, the harness is gonna read them
drchaim··on Apache Burr: Build reliable AI agents and applications
I just create a MVP chatbot for a client that has a Django app. I took the route to no frameworks. Claude/codex wrote the agent loop, the tools, the streaming..it’s working well for the MVP, we’ll see
drchaim··on PgDog is funded and coming to a database near you
Good stuff, although I’m not quite sure about the fast OLAP use case.

If you’re already sharding by tenant for other reasons, OK… But I see CDC to a true OLAP system as more scalable.

PostgreSQL still needs real columnar tables in the core, hopefully one day

drchaim··on Building an HTML-first site doubled our users overnight
I wish more people take this approach, specially public services.
drchaim··on Ask HN: What are tools you have made for yourself since the advent of AI?
- a personal and private webpage for: health: garmin metrics, apple health metrics, blood tests, rx.. - a kind of readitlater and bookmark index - personal finance: wip - in my homelab only available within tailscale.

The final idea is to own all my data, but I’m still on it.

Pretty happy so far

drchaim··on Harness engineering: Leveraging Codex in an agent-first world
But this is almost what we have been doing for the last 3/5 months, isn’t?
drchaim··on The Smart TV in Your LivingRoom Is a Node in the AIScraping Economy
I just checked,I have AdGuard for the whole network. On the TV, 80% of requests are blocked; across the entire network, around 50%. crazy.
drchaim··on I made my phone slow on purpose
Actually seems like a good idea. It's like when I use a 2012 laptop. I can't last more than 30 minutes on it. Probably a LAN proxy that throttles the network for some devices...
drchaim··on Claude Opus 4.8
i just want to use anthropic models under subscription with other agents!
drchaim··on Python 3.15: features that didn't make the headlines
Oh, my beloved Python, for nearly 15 years I wrote you. I miss you, but I no longer do — it's not your fault, life has changed.
drchaim··on Anthropic acquires Stainless
X: What are you folks doing?

A: Writing docs at an SF AI company for $500k TC.

B: Designing, maintaining, and implementing all features for a platform in the IoT sector in Spain — alone — for €40,000.

A: Spain? I just bought a villa near the beach, close to Alicante. Do you know it?

B: Yes..

drchaim··on Gmail registration now requires scanning a QR code and sending a text message
It was easy to see coming, and it’ll spread further and to more services. In fact, recently they even forced old accounts to log in or they would delete them.

It’ll happen with social media accounts and other things too. The account creation date is going to become an even bigger heuristic in their spam models.

drchaim··on Claude Opus 4.7
four prompts with opus 4.6 today is equivalent to 30 or 40 two months ago. infernal downgrade in my case.
drchaim··on Show HN: Plain – The full-stack Python framework designed for humans and agents
that's so true, I still prefer function based views
drchaim··on Hisense TVs add unskippable startup ads before live TV
The other day I was at a spa, they had a TV in the background showing a channel with relaxing images, but after 5 minutes ads started playing.I don't think the spa staff even knew about it. we're fucked
drchaim··on Red Hat takes on Docker Desktop with its enterprise Podman Desktop build
Is anyone paying for this things?
drchaim··on Show HN: Django Control Room – All Your Tools Inside the Django Admin
Good idea. If you add a kind of skill/prompt you’ll get a lot of other components from the community ;)
drchaim··on Show HN: ClickHouse Managed Postgres
I always thought clickhouse would release a kind of oltp engine syncable with the olap one, in their core, compatible with postgres clients. pretty sure the recently launched managed postgresql is just a shortcut :)
drchaim··on Fast, reliable Postgres natively integrated with ClickHouse
I always thought clickhouse would release a kind of oltp engine syncable with the olap one, in their core, compatible with postgres clients. pretty sure the recently launched managed postgresql is just a shortcut :)
drchaim··on Starlink updates Privacy Policy to allow AI model training with personal data
For global companies like Starlink, complying with the privacy laws of every country must be a nightmare. In fact, it really surprises me that they actually follow them to the letter in practice. I’d bet that internally and technically they aren’t fully complied with, but there’s no way to know
drchaim··on CLI agents make self-hosting on a home server easier and fun
My workflow is a bit different in the sense I open my claude session in my laptop, at the directory of my ansible homelab code, and I also give Claude access to ssh to my homelab. But at the end it's almost the same, great tool.
drchaim··on Go ahead, self-host Postgres
I’ve been managing a 100+ GB PostgreSQL database for years. Each two years I upgrade the VPS for the size, and also the db and os version. The app is in the same VPS as the DB. A 2 hour window each two years is ok for the use case. No regrets.
drchaim··on Python is not a great language for data science
Python was a great language for data science, when data science become a mainstream thing.

it was easy to think about the structures (iterators) it was easy to extend. it had a good community.

And for that, people start extending it via libraries.

There are plenty more alternatives now.

drchaim··on Ubuntu LTS releases to 15 years with Legacy add-on
After almost 10 years using ubuntu for vps servers, I’m tired of update them every two years. I would prefer a rolling release distribution, but i don’t have time to select one and make the switch :/
drchaim··on Helping Valve to power up Steam devices
So proud to see a Spanish company working on this low-level stuff
drchaim··on Self-hosting a NAT Gateway
I'm not to much into networks, although I've been sysadmin my vps for years. why I would need a NAT Gateway? it's not enough with a good set of rules of ufw or similar software?
drchaim··on Pg_lake: Postgres with Iceberg and data lake access
More integrations are great. Anyway, the "this is awesome" moment (for me) will be when you could mix row- and column-oriented tables in Postgres, a bit like Timescale but native Postgres and well done. Hopefully one day.
