Level up your SRE Game — Best of this week — 12th March 2023
“We must be willing to roll the dice and lose. Prepare, at the end of the day, for none of it to work.” — Ryan Holiday
I compile Site Reliability Engineering/DevOps-related articles every week and help you keep up your learning game.
This week we covered:
- Most asked DevOps Interview Question
- HTTPie story of 54k Github Stars lost
- Mesh WiFi
I also write about the tools and tips related to Software Development and SRE regularly on my Linkedin profile. You can check out my profile here: https://www.linkedin.com/in/vikasyadav94/
Most asked DevOps Interview Question
One of the most asked questions in SRE/DevOps interviews: What happens when you type a URL in your browser?
How a candidate responds to this question tells about the insights they have into the overall system — so when things go wrong — you can rely on the candidate to find issues in the right place.
You can wrap up the answer to this question in 5 minutes — or you can take an hour if that’s what the expectation is.
Overall structure
-> IP Address lookup — DNS Resolution
-> TCP Connection establishment
-> Lifecycle of how the packet travels from your system to the server
-> HTTP request + SSL handshake
-> Request — Response Lifecycle (Including browser rendering)
Bonus: Multiple parallel connections to speed up page loads
There are tons of blogs which can help you with this question: Here are some of my favourites:

HTTPie story of 54k GitHub stars lost
HTTPie celebrated 10 years since its first commit with 54k GitHub stars, but then lost them all — find out what happened! 💔
-> HTTPie became popular, attracting a community of 54k stargazers and 1k+ watchers on GitHub.
-> The repository of HTTPie accidentally became private for a moment, causing GitHub to cascade-delete their community which took 10 years to build, resulting in the loss of 54k GitHub stars.
-> The loss of GitHub stars was due to an unfortunate sequence of events where the founder thought he was inside a different repo and made HTTPie’s repository private.
It’s funny and interesting at the same time.😄 More of it here: https://lnkd.in/e_Py-5M9
Moral of the story: Read instructions very carefully when there’s a lot at stake.

Mesh WiFi
Looking to say goodbye to buffering, dead zones, and unreliable WiFi coverage at home or in the office? Look no further than Mesh WiFi!
Not only does Mesh WiFi improve signal strength and reliability, but it also offers a range of other benefits, including easier setup and management, better security, and the ability to connect more devices simultaneously.
