In this post, I talk briefly about trace sampling in Opentelemetry.

In this post, I will share how to integrate opentelemetry tracing with GCP logging.

We all make typos from to time, and it is time-consuming to do this manually.

In this post, I want to share how to export the traces generated by your FastAPI application to the GCP observability platform.

With OpenTelemetry, you can easily trace a single request across multiple services in a distributed system.

Recently, I was working on migrating our Elasticsearch cluster to serverless.

In Elasticsearch, when you index document to an index, if you do not specify the mapping for the field, Elastic will use dynamic mapping to infer the data type for your field.

In our work, we are using renovate to update the dependency packages for Python projects.

To make python plugins work in Neovim, we need to set up the python provider properly.

Notes about how to use ripgrep to search hidden files and configuration related to Neovim.

We have a Python project where there are several developers, and we have a mature CI pipeline to do code linting, formatting check for python, yaml, json, and testing etc.

A major Neovim release (version 0.12) has been released a few days ago, after more than one year from the last major release (version 0.11).

When unit-testing a function that make multiple external calls/requests, we want to mock the actual call and return the mock results.

Previously, our projects are still using the old Python 3.10, which will be deprecated soon this year.

In python projects, we always need a linter to catch potential issues and enforce best practices.

When I am working on a Python project, I am using black to format the code, so that we have a unified format across the code base.

In this post, I compare the object vs nested type used in data mapping in Elasticsearch.

When you do code testing using pytest, pytest can do sophisticated changes to your logging.

In Elasticsearch, when we index documents to an index, by default the source of the document is stored in meta field _source.

Recently I was trying to sync my hiking course from Garmin connect to my Garmin Forerunner 965 and found that it does not work.

In Elasticsearch, you can use wildcard in a lot of the index operations.

This post will give a quick summary on how to import GPX route into Garmin watch.

When I try to run pytest locally for a Python project, I noticed that the import in those test scripts may fail if I run pytest in different directories.

In this post, I would like to compare several speakers that are relatively small in size and are suitable as desktop speakers.

Although neovim has built a lot of modules to ease the use of Lua, sometimes we may still want to use packages from LuaRocks.

The version conflict error is often seen when doing document indexing operations in Elasticsearch.

In Elasticsearch (ES), you can run a task and check its status with the task API.

In Elasticsearch, there is index API where you can index a single document to an index.
