#debugging #automation #softwareengineering Useful Logging Logs are one of the most basic and vital sources of information when debugging an application. Here are a few tips to make your logs more useful: Aggregation is a must. In a distributed system, logs must be aggregated into a single location so that they can be queried. Related logs should be linked by a unique, queryable identifier. Logs that originate from a single HTTP request should all have the same ID so that the flow of logic and data can be easily queried....

Returning an interface in Golang will reduce type safety and increase complexity of your code. Instead of returning an interface, you should return a concrete type and pass it directly to a function that accepts an interface your concrete type implements.

Playground , Repo Why do you need concurrency limiting? Concurrency limiting in your go application might be necessary to limit overuse of a specific resource. This could be an API rate limit, slow network connection, slow disk I/O operation or limited CPU/RAM. Starting a huge number of go routines that use a limited resource could cause your application to crash. If you are experiencing crashes or errors on a resource intensive task then I would recommend implementing a concurrency limiter....

Part 1 , Part 2 , Part 3 , Part 4 , Part 5 In Go, critical sections refer to parts of your code that manipulate a resource which must be accessed by only one goroutine at a time. By using a mutex, you can temporarily lock a critical section, perform the operation, and then unlock it, allowing other goroutines to access the resource. Attempting to lock a critical section in a goroutine will block execution until the lock can be acquired....

While similar in some ways to software development, live coding interviews demand a unique approach. In everyday software development, you build knowledge and experience over time, getting more proficient each day. In a live coding interview, you’ll be expected to showcase your grasp of essential software development concepts, as well as data structures and algorithms, all within a time frame of roughly 45 minutes. Most data structures and algorithms are actually the first thing implemented in any language, so it’s extremely rare for a software developer to re implement a data structure in the day to day job....
