✅ Go: Using pointers to reduce copies is premature optimization
When deciding whether to use pointers or values in Go, the size of the data being dealt with is a crucial factor. For small or negligible amounts of data, it doesn’t matter much. However, with extremely large variables, passing by pointer can be necessary to avoid excessive copying. The performance impact of pointers depends on the CPU’s caching behavior, and there is no general rule for when to use pointers. Instead, focus on expressing your intent in code and consider profiling for optimization if copying large values becomes a bottleneck.
Memory-wall problem
The memory wall problem occurs when a processor’s speed surpasses the rate at which data can be transferred to and from memory, resulting in performance slowdowns. CPUs mitigate this by using L-caches, which are small and fast. Understanding memory allocation and cache utilization is crucial for optimizing program performance.
GitHub actions and Go private modules

✅ Go: Tracing HTTP requests
The HTTP protocol is fast, secure, and reliable. However, it needs other protocols and services to work properly, and when things don’t go well it is necessary to have access to detailed information about the time spent in each step. The steps to make an HTTP call are as follows: DNS Lookup The client sends a DNS query to the DNS server. The DNS server responds with the IP for the name.
Go Toolchains
Starting in Go 1.21, the Go command allows for switching between different versions of the Go toolchain based on module requirements, and it automatically selects the appropriate toolchain version. The GOTOOLCHAIN environment setting and the go and toolchain lines in the go.mod file determine the toolchain version used
Golang vs Python: The Ultimate Battle in DevOps
In the world of DevOps, two programming languages are often pitted against each other: Golang and Python. Both languages have their own strengths and weaknesses, and choosing the right one for your DevOps needs can be a tough decision.
