Hello. Mackerel sales engineer 
id:a-know here.
I’m in the habit of checking the weather forecast everyday before I head to work and the temperature just doesn’t seem to want to warm up. I’m ready for a season where I don’t need my coat.
Over the last couple of weeks we’ve announced our participation as a sponsor of JAWS DAYS 2017, but the day is finally upon us with the event being held tomorrow.

An interview article was written about Mackerel’s development process and tools!
Since the launch of the service in September 2014, Mackerel has made consecutive weekly releases (By the way, this week marks 138 weeks straight!). We’ve been receiving many questions about Mackerel’s development process and its flow, but this time we’ve been interviewed by Mr. Shiraishi, a member of the HTML5 Experts.jp editorial department. The article was released today!
