async没有什么magical的，就是个语言内部实现的context switch，不用OS的那一套而

The suit is the vehicle by which you create a first impression, says Norman
Fryman, former CEO of The Grief Companies and current consultant to
Bidermann, manufacturers of tailored men’s clothing. He goes on to explain
that a suit’s silhouette, drape, and color provoke a conscious thought in
the mind of the recruiter of what you are all about.
Let’s face it, a recruiter not only judges your resume and communication

This is my first good deals post so sorry if this isn't quite a "hot deal" .
I happen to be shopping for headphones and I stumbled upon a pair of my own
headphones that I already own. I can attest to them sounding great for the
price (dark, warm sounding with decent bass), having great build quality (
everything is either metal or very thick plastic construction), and having
good isolation. They also fold up nicely into a pleather pouch.
