Save draft mail in Zimbra web client using ChromeDP
2020-07-03
As an engineer, I want to automate everything as much as possible. This CLI tool is created to save a draft mail in Zimbra web client.
Read config file:
1func initConfig() { 2 if cfgFile != "" { 3 // Use config file from the flag. 4 viper.SetConfigFile(cfgFile) 5 } else { 6 // Find home directory. 7 home, err := homedir.Dir() 8 if err != nil { 9 fmt.Println(err) 10 os.Exit(1) 11 } 12 13 // Search config in home directory with name ".zwc" (without extension). 14 viper.AddConfigPath(home) 15 viper.SetConfigName(".zwc") 16 } 17 18 viper.AutomaticEnv() // read in environment variables that match 19 20 // If a config file is found, read it in. 21 if err := viper.ReadInConfig(); err != nil { 22 log.Fatal(err) 23 } 24 25 fmt.Println("Using config file:", viper.ConfigFileUsed()) 26}
Google Calendar CLI

Our company allows us to work from home some days a week. To do that, we have to create an event in Google Calendar.
I created this tool to run it from CLI.
First, take a look at this quickstart.
Create initical code by running:
1$ cobra init 2 3$ tree -L 2 4. 5├── LICENSE 6├── cmd 7│ └── root.go 8├── main.go
Create event
command:
1$ cobra add event 2$ cobra add insert -p 'eventCmd' 3 4$ tree -L 2 5. 6├── LICENSE 7├── cmd 8│ ├── event.go 9│ ├── event_insert.go 10│ └── root.go 11├── main.go

I’m reading Building RESTful Web Services with Go. And in chapter 4, there is an example to play around with SQLite:
1db, err := sql.Open("sqlite3", "./books.db") 2if err != nil { 3 log.Fatal(err) 4} 5 6statement, err := db.Prepare("CREATE TABLE IF NOT EXISTS books (id INTERGER PRIMARY KEY, isbn INTEGER, author VARCHAR(64), name VARCHAR(64) NULL)") 7if err != nil { 8 log.Fatal(err) 9} else { 10 log.Println("Created table books successfully") 11} 12statement.Exec() 13 14statement, err = db.Prepare("INSERT INTO books (name, author, isbn) VALUES (?, ?, ?)") 15if err != nil { 16 log.Fatal(err) 17} 18statement.Exec("Life is a joke", "The Javna brothers", 123456789) 19log.Println("Inserted first book into db") 20rows, err := db.Query("SELECT id, name, author FROM books") 21var tempBook Book 22for rows.Next() { 23 rows.Scan(&tempBook.id, &tempBook.name, &tempBook.author) 24 log.Printf("ID: %d, Book: %s, Author: %s\n", tempBook.id, tempBook.name, tempBook.author) 25}
How do I build this blog?

Recently, I decided to find a new job as a Golang developer. So, I updated my resume, sent to my friends to ask for review. Then I submitted it enclosed herewith a cover letter to recruiters. Some didn’t reply, and the other replied with a message like this “You are so good, but I’m so sorry…”.
What is the reason?
As you can see in my resume, I started my career as a .NET developer, then my passionate on Linux and open source lead me to a different direction: system administrator. I dedicated myself to this role for a significant period before transitioning back to work as a Golang developer 2 years ago.
