Building Technical Sophistication As A Developer Idea and concept wise it’s something we all developers are quite aware of. I first came through this exact term, “technical sophistication” in Michael Hartl’s article in Learn Enough Society. The basic idea is as developer one requires a certain set of skills which can elevate their overall vision and can see things in a broad sight. One need not be technically proficient at everything but having good understanding of fundamentals enables us to debug and reach the solution faster.

We know the story of how linux came to be.

Personally I haven’t extensively used redis. My limited understanding of redis would be summarized as: redis is in-memory database, stored in RAM (making use of underutilized RAM space in servers) being stored in primary RAM it’s very fast being stored in volatile storage (RAM) it vanished as system goes off, however there are ways to persist it in the file system redis uses key value storage and supports quite a few datatypes including list, hashmaps, geocodes, etc how companies like twitter have made an extensive use of redis in caching for faster retrieval (low latency when the throughput demand is high) it can be used as pub-sub model (message broker) Trivia: Redis is an acronym for “Remote Dictionary Server”

Git tracks file permissions too Although I have been extensively using git for quite some time now I never happened to come across this situation where you change the permission of the file which is tracked by git. Yes, by default git is configured to track the changes in file permission mode too. Just to experiment with the idea, I created a dummy repo and ’touched’ an empty file.

Recently I came to know about a wonderful online learning resource called Learn Enough. (https://www.learnenough.com)[Learn Enough] is an initiative by (https://twitter.com/mhartl)[Michael Hartl] who is popular for his highly acclaimed Ruby on Rails tutorials series, which was, at one point, Wikipedia founder (https://en.wikipedia.org/wiki/Jimmy_Wales)[Jimmy Wales]s’ favorite book. I came to know about learn enough through one of the links in StackOverflow answer where I was reading through some answer on UNIX. After going through some of the articles on (unix, git, dev-environment) I was amazed at the simplicity and the narrative way of teaching.

How I came to know about it So, I am a regular reddit user and it’s one of my favorites online communities. While browsing through subreddit posts, there is a feature in the reddit web-app where you have keyboard shortcuts for browsing: N for next post, P for previous post and so on. I found it very convinient and easy to use especially because you don’t have to take your hands off the keyboard.
