drchaimon Show HN: A benchmark for analytical databases (Snowflake, Druid, Redshift)

I would say deep optimizations in every aspect of the data cycle. From storing to querying data is heavily optimized. I recall an online meetup where a 10ms gain after a patch was huge celebrated. That kind of things compound over and over and make a really fast data platform for that use cases.

drchaimon Jasonette – Native App over HTTP

I built my last mobile app with Ionic, every time I created a new page, new endpoint sending JSON i was wondering why I wasn't sending just Ionic html from the server, or that the JSON contains the UI.

Now even to a small UI change I need to redeploy the app to app stores, which is ...tiresome.

A pity I didn't know this way before.

drchaimon The Gov.uk Design System is now live

Always I go to any .gov.uk website I only feel envy comparing it to the .gob.es I need to deal with from time to time.

drchaimon Amazon Elastic File System Update – Sub-Millisecond Read Latency

I'm thinking of a ClickHouse database which files are on EFS. Clickhouse is usualy much faster than RDS/Redshift for the use cases is designed for, and having EFS will ease a lot replication efforts.

drchaimon Ask HN: Good open source alternatives to Google Analytics?

As I predicted around 2018, most or all analytics/events products will eventually move to ClickHouse or related technology (forks).

Plausible: ClickHouse

PostHog: ClickHouse

Panbelbear: Clickhouse

https://pirsch.io/: ClickHouse.

PD: I should have a blog or something where I put this predicts :)

drchaimon Databases in 2021: A Year in Review

This is the way for my also.

drchaimon Show HN: Distributed Tracing Using OpenTelemetry and ClickHouse

I've been thinking about mixing OpenTelemetry and CH for a while. There is a wild competition in this area, hope you luck and fun!

drchaimon Ask HN: Those making $500/month on side projects in 2021 – Show and tell

Congrats on this! I've also though about this kind of app to a solution for the "app fatigue". I really like the design, simple and fast.

drchaimon What's New in ClickHouse 21.12

I made a PoC to replace our current ElasticSearch cluster with Clickhouse 20.10. 5x gains in space and 3x gains in QPS, without changing too much the schema model. It's still in a PoC repo, priorities I guess..

drchaimon TimescaleDB raises $40M

Congrats to the tsdb team. I've tried the database extension months ago and it works perfect for my use case standalone. I just need to integrate it with Django, which is not easy given the current schema of the database and the way Django creates defaults autoincrements and PK, but I'm sure there will be a workaround for that.

drchaimon Ask HN: Are you/your company still using Python 2 in production?

Only one project is still in Python2. A project that were transfered to my without test, docs, etc. and a component heavily relying in sockets, unicode, regex that i'm quite scare to port to python3.

I'll guess I will decouple that component from others and I'll keep it in python3 while porting the rest to python3 in the future.

drchaimon Apple sends a letter to Hey: Change your app or get out of the App Store

I'm probably missing something, but can't Hey just make subscriptions in their page and let the App from free in the App Store?

Is the same as gmail, I can pay for a Google Suite, but the app is freely distributed in stores.

Basecamp should have great products (I've never used them), but it seems they are using this as a marketing strategy.

drchaimon Keycloak: Open-source identity and access management

All I can say is they don't seem to donate Django project.

I'm so much interested in that book to improve my business skills. Any reference?
