pantuzaon Incident Metrics in SRE – Critically Evaluating MTTR and Friends [pdf]

I found this report really on a modern path. It might be interesting for deriving useful Incident Metrics for companies.

pantuzaon Translating lava lamps pictures into encryption keys

Loved that part: "Because the lava lamp wall is in the busy lobby of the Cloudflare headquarters, this happens all the time. People come and go in the lobby, walking by or stopping to talk in front of the lamps. Such obstructions become part of the randomness that the camera captures, so people partially blocking the camera's view of the lava lamps actually helps generate entropy."

pantuzaon The enigmatic Portuguese R (2013)

We pronounce 'r' in Portuguese as 'h' in english words. For example: the word 'mice' in Portuguese is 'rato' which we pronounce as if it was 'hato'. Similar to 'hat', 'hate' or 'hit'.

But never as the english word 'rat'. For us it sounds like 'rrrrrrrat', because the 'r' is too long in the pronunciation.

Summarizing: Portuguese don't use long 'r' phonemes when the word starts with 'r'. We usually pronounce as if the word starts with 'h' in english.

The long 'r' is used when 'r' or 'rr' appears in the middle of the words.

pantuzaon Ask HN: Setups for Remote Developers

I think a good start is to have a VPN. Only within the VPN developers are able/allowed to communicate with the INTERNAL parts of your cloud for things like test, staging environment, databases and so on.

I don't know about Azure, but I know other clouds have services to integrate your VPN with their environment allowing you to directly transit between them.

Hope that it brings some kind of insight to your research ;]

pantuzaon How to Use AWS Infinidash with Node JavaScript

I will post an example here but I am just waiting npm install to finish in order to test if the code works. Get back soon..

pantuzaon Docker Compose is now in the Docker CLI

You will be able to simply run `docker compose up`. It also reduces the number of package/tools dependencies on your project setup.

pantuzaon Pg_tmp – Run tests on an isolated, temporary PostgreSQL database

Super cool and useful. In the page there is this link about A guide for accessing the features of PostgreSQL in test-driven development which is nice: https://www.youtube.com/watch?v=4Vigf4NG6-s

pantuzaon Tiny Container Challenge: Building a 6kB Containerized HTTP Server

Interesting discussion. Just a comment about the size o Golang binary. In the post example it uses standard fmt library. fmt by itself, adds several megabytes to a binary when compiled. Removing it would reduce binary size.

pantuzaon Semgrep: Semantic grep for code

Really outstanding those guardrails rules from semgrep. Useful to enforce code. Thanks for sharing the tool.
