Go vs C benchmark. Could Go be faster than C?

During last semester I was attending Multiprocessor Architectures course, given at Facultad de InformÃ¡tica where I study my Computer Science degree. As part of the assignments due to pass the course, we had to do several programs written in C to benchmark matrix multiplication by testing different techniques and technologies. First of all we had to do a secuential program in three different versions: A normal one where the result matrix is ordered by rows and the loops range the matrix by ...

Learning Go

This year I'm going to try a new programming language - Go. I had this notion that compiled, type based languages are overly complex and reduces developer efficiency. However, after doing some reading about Go, it appeared to take a different path from the rest and felt like something worth trying. Acquainting a programming language is a journey. First few steps you take with it will define your perception about it. These first few steps went well for me with Go and it felt lik...

Performance is a Feature

We've always put a heavy emphasis on performance at Stack Overflow and Stack Exchange. Not just because we're performance wonks (guilty!), but because we think speed is a competitive advantage. There's plenty of experimental data proving that the slower your website loads and displays, the less people will use it. [Google found that] the page with 10 results took 0.4 seconds to generate. The page with 30 results took 0.9 seconds. Half a second delay caused a 20% drop in traffic. Half a seco...

The First Bite on etcd Code

Etcd, one of the crucial components of Kubernetes. If APIServer is the heart, then etcd is the blood vessel that sends the end state of Kubernetes resources to various “organs”, providing high-speed, stable storage, and supporting APIServer’s high load performance. What if the etcd is not working properly? Just the condition as someone has a vascular disease. The deeper you know about them, the better diagnose you can make when issues occur. from unspl...

When and How to Use the Go Channel

Go’s concise structure and powerful native library enable us to hit the ground running easily. It is more efficient than Java or Python when implementing the same functions, especially its concurrent programming, which is very handy and widely admired due to its goroutine and channel. goroutine and channel has much to dig into, and let’s start with channel, which I used to consider narrowly as a message queue to transfer data between gorouti...

Ruby is beautiful (but Iâ€™m moving to Python)

The Ruby language is beautiful. And I think it deserves to break free from the Web. I think the future of Ruby is firmly stuck in Web development, though, so Iâ€™m going to invest in a new language for data analysis, at least for now. This is a look at the fantastic language I came to from Java and a look at a possible candidate. (Update: Iâ€™ve since written a followup.)Java to RubySix years ago, I added Ruby to my technical arsenal. I learned C++ and Java in high school, and I p...

How to check when an API is introduced in GoLang

Normally people would not pay much attention to which GoLang version is being used as lots of functions are backward compatible. However there are cases where GoLang version does matter as some functions may not be supported by old version of GoLang. For example, strings.Builder is introduced in Go 1.10, but below code would fail to be compiled on Go 1.10. package main import ( "fmt" "strings" ) func main() { var b strings.Builder b.WriteString("polarisxu") fmt.Println(b.Cap()) } The ...
