As a foreigner in Taiwan, I not only read the local news, but also Malaysia news and some international news. As a software developer, I am also interested in the technology news. But I have to visit different news websites for those news, so I wished I could just read the news from specific countries and sources within a website. Since I am learning Go, I decided to use it to create a website that satisfies my own needs. So I created a website with the following features:

• Search by country, source or date range
• Mobile friendly
• User Module (WIP)
