Vasin Permsup was known as the founder and owner of Provision publishing, a Thai publishing company, specializing in Technology topics, trends and life styles. For the older geeks, using MS-DOS at its prime during the 80s and early 90s, you might remember a Thai book called DOS Manual; well Vasin was the sole author of the book. We asked him to share his experience in the book business during this digital media. You might contact him at Twitter.com/VasinP, VasinP.com and www.provision.co.th.
