in this case medium is relative to the projects I've worked. Bad expression anyway.

I threw 1M tokens for nothing in a medium codebase.
drchaim··on Why is Google still serving dodgy ads?
I’d love to know how much Google has made from accidental clicks since it started. I used to see my mum make a couple of mistaken clicks here and there on her computer; now on mobile it’s easily 10x worse. Sometimes because she doesn’t realize they’re ads, other times she tries to tap the X and it opens… It’s insane

drchaim··on Every Millisecond Counts
Good post, thanks for sharing. I discovered CH around 2018, and I knew it would change the analytics space. I spent countless hours studying it on my own and promoting it at work (when it made sense). I also tried to land a job at companies using it, but nothing happened :(.

I still check the monthly changelog, even though I do quite different things at work these days.

The idea of custom software on the fly is coming
drchaim··on Show HN: WaveHouse – Supabase for ClickHouse
Good one!
drchaim··on Does anyone run Postgres without PgBouncer?
I do. I run Postgres in the same server as the app in some apps, with no pgbouncer, no regret at all after 10+ years.
drchaim··on Tailscale didn't stop the Hugging Face intrusion
How are you folks handling secrets in a simple way?

- sops , ansible vault and similar seems too weak given the agent is gonna read them at some point if you have the pass available. - proxy injection seems too complicated and doesn’t cover all use cases.

drchaim··on Demis Hassabis has a plan to harness AI safely
It's not clear to me whether this is being done with genuinely good intentions, or if it's just a way to put barriers in front of open-source models. We'll see.
drchaim··on Postgres rewritten in Rust, now passing 100% of the Postgres regression tests
i highly doubt you can make it faster than clickhouse, but happy to see it.
drchaim··on Ask HN: Is anyone experimenting with different ways of using LLMs for coding?
This is not my case. Today Claude code coded three features in my client saas just perfectly. Medium complex ones but perfectly from the plan, tests, linter and pr. A good CLAUDE.md is enough. Skills for auxiliary tools like sentry, grafana…

too slow or broker right now
drchaim··on In praise of memcached
WHEN do you move to Redis/Memcached? None of my projects have exceeded 1000 rps at peak, and in none of them have I felt the need to move from unlogged PostgreSQL tables to Redis.

Just trying to get a sense of where people draw the line.

drchaim··on The minimum viable unit of saleable software
Brandur of course knows more than me, and his framing sounds correct. I would be worried about whether the TAM of Go + Postgres is enough for business sustainability, but that says probably more about my fears than the reality in this huge market called “internet”
drchaim··on Developers don't understand CORS (2019)
I understand CORS each time I need to fix or to avoid them ;)
drchaim··on Pre-2022 Books
This will happen with social accounts, news articles..I set the date pre 2023, but we all have some date in mind. I don’t like it, but it’s what it is
drchaim··on Supermarket giant Tesco sues VMware for breach of contract (2025)
Having VMware in 2026 is a sign of low tech.
drchaim··on Ten years of ClickHouse in open source
Actually, there was no search, only on-the-fly aggregations/filtering over "big data". ES was kind of famous at the time, although not the best tool for that job.

afaik CH introduced FTS rececently.

drchaim··on Ten years of ClickHouse in open source
I discovered ClickHouse around 2017-18 and built a PoC to replace Elasticsearch: 5x better storage and qps, in a couple of weeks.

Managers rejected it because it wasn't well known and was seen as "some database made by Russians."

On a personal level, it's quite sad to have seen that train coming so early and not been able to get on board.

drchaim··on Databricks Launches LTAP: A Unified OLAP/OLTP Data Architecture
No benchmarks, no pricing, no examples..
drchaim··on Running local models is good now
really want to try local models, but I don't have the hardware yet. Probably I'm the only one here still using a Mac Mini m1 8gb 2020. :/
drchaim··on How TimescaleDB compresses time-series data
I've tested the migration of the main table (IoT data), from 300GB to about 25GB in a non-production environment. Everything seems right, but I'm still delaying/procrastinating the prod migration, so I wanted to know how it is going for other live projects.
drchaim··on How TimescaleDB compresses time-series data
I'm not into k8s things, but thanks. Still run this project with Postgres in the same machine as the app. No issues so far after 8 years. :)
drchaim··on How TimescaleDB compresses time-series data
Is anyone running self hosted timescale? How is it going? I have a use case for it, but don’t know why I’m a bit afraid of using it.
drchaim··on Ask HN: How to deal with agents constantly messing up padding/alignment in UIs?
I go further, how do you work in UI/frontend tasks? As a backend I know how to control agents in backend code, but in FE I am almost lost. Any hint isn’t appreciated
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.
