> I (Steven) is currently experiencing server upgrading issue (today is 30 Nov 2016)... https://cpbook.net will be revived soon when I am done with Semester 1 teaching in NUS next week.
The good news is, using the Wayback Machine, I was able to extract the link for purchasing the hardcover book:
https://www.lulu.com/commerce/index.php?fBuyContent=13872302
Pro tip: Use the coupon code FWD15 for an additional 15% off making the hardcover cheaper than the Amazon paperback price.
The smaller version is nice for reading while on the go/during a commute but not as nice for when you want to have it on your desk as a reference while working through problems (which you'll be doing a lot with this book). With the small version I have to find things to weigh down both sides just to keep it open on my desk so I can glance at it.
It doesn't have a lot of advanced material for more experienced competitors though.
