"As YouTube dives headfirst into short-form videos I am glad I decided to build InterviewReady. I had the choice of trying to monetize my channel through sponsorships and product placement or build my own website. I figured that a large part of my audience are working professionals who value time over money. It was a little scary at the start. The support tickets feature requests content suggestions felt overwhelming. We had to build our own product pipeline design customer support marketing sales tech content etc. It is the road less traveled. That has made all the difference. P.S."

"Part VII: Covid Engineering team strength was cut down to roughly [----] engineers. The number of microservices did not increase which is an important lesson for developers: Once you bring in a service it's nearly impossible to remove it. The time testing risks involved is too much. When you leave the org no one wants to touch that service. Let it run on prod what is the risk vs. benefit ratio"

X Link 2024-01-27T07:13Z 44.7K followers, [----] engagements

"Key lessons: [--]. Uber says: In small organizations the operational benefit likely does not offset the increase in architectural complexity. In other words- Don't go for microservices to scale your tech go for microservices when you must scale your team. [--]. Efforts to reduce tech debt make sense after the MVP is proven. Prioritise.

"New blog on system design. I came across this question when going through Facebook's Memcached Paper. When scaling out cache servers horizontally should we choose to replicate data across them Or should we shard data into unique key ranges Here is what I learned: Thank you to the engineers at Facebook https://interviewready.io/blog/data-replication-vs-sharding https://interviewready.io/blog/data-replication-vs-sharding"

"Story time. A frontend engineer was strangling a back-end engineer. When asked why- "He changed the client version from 1.1.3 to 1.1.4." the FE explained. "So" "So SO He made a breaking change on the patch update The company stock is down 15% and the CEO wants to know my current location" This is a good time to talk about API versioning. Versioning has the following format: MAJOR.MINOR.PATCH (1.1.3) [--]. MAJOR: May break expectations (not backwards compatible). [--]. MINOR: Adds some new features without breaking anything (safe to move). [--]. PATCH: No new features just bug fixes and improvements"

"Language is primarily a tool for communication rather than thought. "evidence suggests that language is unlikely to be a critical substrate for any form of thought. Although access to words syntactic structures or non-linguistic symbols can facilitate performance on certain cognitive tasks language is doubly dissociated from thinking and reasoning."
