Let’s say I have a package named actuallykasi/pkg/sample/v1/api. Inside this package there is test function TestGetCurrencyHandler as follows. 199func TestGetCurrencyHandler(t *testing.T) { 200 router := mux.NewRouter() 201 tests := []struct { 202 Name string 203 Method string 204 URL string 205 WantCode int 206 WantResponse []byte 207 }{ 208 { 209 Name: "InvalidCurrency", 210 URL: "/currency", 211 WantCode: http.
Some objects are simple and can be created in single constructor call. Other objects require a lot of ceremondy to create. Peice wise construction. builder provides an API for constructing an object step-by-step.
type PersonBuilder struct{ person *Person }
func (b *PersonBuilder) Lives() *PersonAddressBuilder{ return PersonAddressBuilder{*b} } func NewPersonBuilder() *PersonBuilder{ return &PersonBuilder{&Person{}} } type PersonAddressBuilder struct{ PersonBuilder }
SOLID Design priciples by Rober C. Martin Single Responsibility principle Open-Closed Principle Liskov Substitution Principle Interface segregation Principle Dependency Inversion Principle Single Responsibility principle A type should have one responisibility. Seperation of concerns. God object a terrible idea!
Open-Closed Principle OCP Open for extenstion, Closed for modification. Specification pattern.
Liskov Substitution Priciple Interface Segregation Principle You shouldn’t put too much into interface. Smaller interface the better.
Dependency Inversion Principle High level Module (HLM) should not depend on LLM.
EdgeRouter uses ISC DHCP server by default.

Why Do I need DNS over TLS/SSL? I am already using privacy first 1.1.1.1 as my DNS resolver. My DNS queries are still unencrypted. Tcpdump on edgerouter shows which queries my home devices making continously.

Why do I need an Edgerouter? Ubquity’s near enterprise grade linux router gives you fine grain control over your home routing. I can think of several usecases such as
Put entire/some traffic under vpn so I don’t need a vpn client working in every device I am using. Run my personal site (actualykasi.com) from edgerouter so I can cut down hosting costs. (More on how I achieved that in upcoming blog post) Play ground for vlan, nat, bgp and ospf etc.
