We also started with the typical kube-prometheus-stack, but we don’t like Prometheus/PromQL. Moreover, it only solves the „metrics“ part - to handle logs and traces, more quite heavy and complex components have to be added to the observability stack.

This didn‘t feel right, so we looked around and found greptimedb https://github.com/GreptimeTeam/greptimedb, which simplifies the whole stack. It‘s designed to handle metrics, logs, and traces. We collect metrics and logs via OpenTelemetry, and visualize them with Grafana. It provides endpoints for Postgres, MySQL, PromQL; we‘re happy to be able to build dashboards using SQL as that’s where we have the most knowledge.

The benchmarks look promising, but our k8s clusters aren’t huge anyway. As a platform engineer, we appreciate the simplicity of our observability stack.

Any other happy greptimedb users around here? Together with OTel, we think we can handle all future obs needs.

I also heart about lakeFS for data versioning on S3 object stores. Is DVC a contender in this area?

I recommend using your preferred flavor of configuration management tool. It is tricky, especially when you want to provision multiple users in different Grafana organizations, data sources, and their dashboards, but it can be done (I prefer Puppet because of its flexible language, but Ansible should also work).

You could take a look at Postgres + TimescaleDB extension, which offers a nice time_bucket() function on its hypertables[1]. You can also materialize using continuous aggregates („self updating“ materialized views).

I also started with that stack, but swapped out InfluxDB for Postgres + TimescaleDB extension, which adds timeseries workflows (transparent partitioning, compression, data retention, continuous aggregates, …).

I found InfluxDB to be lacking in terms of permissions management, flexibility regarding queries (SQL, joins), data retention, ability to debug problems. In Postgres, for example, I can look into the execution plan of a statement, log long running queries, and so on.

Telegraf as an agent is very flexible; it has input plugins for every task I could want, and besides it’s default „pull workflow“ (checks on defined interval) I also like to push new metrics directly to the Telegraf inputs.socket plugin from my scripts (backup stats, …).

Inline Bundler is a nice way to include gems in a single script file, which proved to be useful for me: https://bundler.io/guides/bundler_in_a_single_file_ruby_scri...

Also not a fan of the touchbar, but since I learned that you can tap on volume and immediately slide left/right, it's ok for me.

In the meantime, you could use the version shipped with macOS:

    ▶ ruby -v
    ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.arm64e-darwin20]

There's a detailed issue[1] on the homebrew repo where you can track their progress. The "Major blockers" section lists go, rust, gcc, and others.

also check out ora_migrator https://github.com/cybertec-postgresql/ora_migrator (another extension from Cybertec) which uses oracle_fdw under the hood.

If you haven't already, take a look at their awesome dashboard http://haya2now.jp/en.html linked a couple of months ago https://news.ycombinator.com/item?id=18046274

https://avogadrocorp.com/ immediately came to mind:

> David Ryan is the designer of ELOPe, an email language optimization program, that if successful, will make his career. But when the project is suddenly in danger of being canceled, David embeds a hidden directive in the software accidentally creating a runaway artificial intelligence.

Did you look into the Razer Blade series? https://www.razerzone.com/gaming-laptops

Did you try http://cmder.net ?

Looks interesting. DIY voice recognition still seems to be in its infancy tho. I guess this is another problem to be solved with mass data.

Jasper http://jasperproject.github.io looks like another contender in this area.

One famous answer to this is: Your problem with Vim is that you don't grok vi. http://stackoverflow.com/questions/1218390/what-is-your-most...

Does anyone use https://hubic.com/en/ ? Their pricing looks crazy-cheap compared to other providers.

In Puppet-land, MCollective ("more than a fancy ssh-for-loop") allows you to query servers by Facter facts.

You probably stumbled over this article about scientists @ Qatar University developing artificial clouds: http://news.bbc.co.uk/sport2/hi/football/9435035.stm

edit: same as above post :)

The widespread use of Puppet also has some benefits:

- lots of documentation

- Foreman ( http://theforeman.org/ , backed by Redhat) as a great alternative to Puppet Enterprise

- projects like GitHub's Boxen ( http://boxen.github.com/ ) to bootstrap your devel machine

- a large repository of modules available: https://forge.puppetlabs.com/

- a couple of books, training, conference, if you like those things

However, I'm very aware of those ugly warts, so there's a lot of potential for a successor.
