While interning, I once had an application that logged every request and response to the Linux file system. That app easily fills up our disks due to traffic. I got confused when I tried to delete log files because disk usage didn’t decrease even aft...
I only rewrite what was written on my pastebin package main import "fmt" func findGCD(a, b int) int { if b == 0 { return a } return findGCD(b, a%b) } func findLCM(a, b int) int { return a * b / findGCD(a, b) } func main() { fmt.Pri...
I don’t do anything except converting the pseudocode from wiki into Golang code package main import "fmt" func fetchFirstPrimeNumbersOf(n int) []int { var result []int // an integer n > 1 if n <= 1 { return result } // let A be an a...
I’ve just woke up and somehow I remember that when I created taboo to trace the error log. And then I think, would it be better if I pass the logger instead of the error log itself? As the context passed, it will contain a sub-logger that has x-reque...
When we talk about crypto-something, we need to talk about Alice and Bob acting as actors in the example section. I hope you don’t get bored with them as I will use them as examples too. Here, Alice and Bob will use RSA for the asymmetric key, SHA256...
Data serialization library in Java could be varied. You can use Jackson, GSON, or anything else. Since there are too many serialization libraries out there, it’s quite tricky to manage Java class attribute exclusion during serialization. Each library...
After I tried to implement BST in Go, it seems like I want to modify the BST to AVL because BST is not a fairly optimal tree data structure. When I said this: To find a specific node you don’t have to go around the whole tree, you need to know that ...
So long since I learned to create BST back then at university. I feel like wanna revisit the BST things, so I make this post. BST is not that scary. You only need to create a tree without duplicated value on each node, then the less valuable nodes go...
Add this on your spring boot project: @Bean @Order(Ordered.HIGHEST_PRECEDENCE) public FilterRegistrationBean<CharacterEncodingFilter> characterEncodingFilterRegistration() { CharacterEncodingFilter filter = new CharacterEncodingFilter(); filter.s...
