I worked with many pro developers in the last decade who preached the same ideas. Adopting them made me an efficient problem solver today.

Here are 10 tricks that only experienced developers know: 🧵👇

#software #programming #developers
1. Always have a plan

Planning helps you learn about the problem, analyse it, and carefully think about the trade-offs. Jumping right into the code is often a sign of inexperience.
2. Optimize only when needed

Pro developers focus on getting things to work rather than wasting time looking for the best possible solution.

If you are struggling you grow your customers & bring new customers open this: 👇

While building @vadelabs, I am learning about how to drive maximum value for our customers.

Here are 10 essential customer funnels you need to know to take your business to the next level🧵
1. The Awareness Funnel:

Your potential customer becomes aware of your company. You must focus on generating interest and curiosity in your product and service. Involves running paid ads, attending events, or creating content.
2. The Consideration Funnel:

Your potential customer actively considers whether or not to buy the product. You must focus on providing more information about the product, features & benefits over your competitors. Involves creating case studies, demos, or educational content.

As a DevOps engineer, you should be familiar with several metrics to effectively monitor and maintain the performance and reliability of a system.

Here are the 10 most important metrics you must know: 🧵👇 Image
1. Availability: This is a measure of the proportion of time that a system is operational, taking into account both the MTBF and MTTR.
2. Mean Time Between Failures (MTBF): This is a measure of the average time that a system operates without failing.

Building reliable software is complex.

Here are 16 lessons I learned the hard way in the last five years as a DevOps engineer 🧵👇

#DevOps #DevOpsCommunity
1. No in-code fallbacks for configs:

If the service can't load the config on startup for any reason, it should just crash. It's easier to diagnose than the result of one borked instance going down an ancient code path due to misconfiguration.
2. Stringent RPC settings:

Zero retries and a timeout like 3X the p99. We are striving for predictability here; sprinkling retries and long timeouts as quick fixes lead to a week-long investigation and headache a year from now.

Networking protocols are the most important concepts to excel as a DevOps engineer.

Unfortunately, most of them don't seem to understand the basics.

Here's a crash course to make you an expert in OSI Model 🧵👇 Image
OSI stands for Open Systems Interconnection. It provides a standard for different computer systems to be able to talk with each other.

7 layers of OSI model are defined as follows : Image
L7. Application Layer:

It interacts directly with the user. Browsers rely on it to initiate communications. Responsible for protocols and data manipulation that the software relies on to present meaningful data to the user. Like HTTP and SMTP Image
