--Josh Bloch (Praise for the first edition)

In Hacker's Delight, Second Edition, Hank Warren once again compiles an irresistible collection of programming hacks: timesaving techniques, algorithms, and tricks that help programmers build more elegant and efficient software, while also gaining deeper insights into their craft. Warren's hacks are eminently practical, but they're also intrinsically interesting, and sometimes unexpected, much like the solution to a great puzzle. They are, in a word, a delight to any programmer who is excited by the opportunity to improve.

Missing Sequins and Threadbare!
Size: 3X-Large, Color: Purple, Size: 3X-Large, Color: Purple
Jacket is great for fit, and is overall okay, but there are large patches where no sequins are attached! For the $59.99 price I paid, I am definitely feeling very disappointed in the quality of the jacket. Of course, I didn’t realize this till after the return window closed! If you order, do yourself the favor and check to make sure the jacket is in good quality!

Nice suit great value
Size: Medium, Color: Light Blue, Size: Medium, Color: Light Blue
Got this suit for my son to wear to a wedding. It arrived a day or two then the except it delivery. I was concerned if it would fit because of the size chart. He is tall and skinny so I got the medium. When he tried it on it fit him perfectly except the waist was a tad too big but with a belt everything worked. I took it to the cleaned to have them press it. Great value, nice quality material, light weight and comfortable for spring/summer events. The wedding was outdoors. He looked very handsome unit. Was very pleased.

Not Seersucker, more a Blue pinstriped suit.
Size: XX-Large, Color: Blue
This is not Seersucker!! Granted the suit will be cool in summer and looks good, but material is a blend. The pants are very large, while the top fits perfectly. I’d go with a regular cut, not slim for better fit. But for the price, no complaints.

Great Suit for Hard to Fit Guys
Size: X-Large, Color: Light Grey, Size: X-Large, Color: Light Grey
This fit my husband perfectly. The elastic in the waistband is great, he was very comfortable all day. The only complaint is that the material is a little thin.
