Netty是目前市面上使用率較高的網絡編程庫。它的架構設計非常明確且層次分明，源碼較為易懂，其中包裝了Java NIO（New IO，新IO）的三大組件：Selector、Channel、ByteBuffer，提供了簡單易用高效的網絡通信庫，其中還實現了自己的內存池管理。Netty的設計基於Jemalloc內存管理庫，同時也實現了很多開封即用的應用層協議編碼與解碼器。本書通過常用的TCP協議完整詮釋了Netty的架構設計與思想，省略了Java語言層面的一些基礎知識，例如變量、面向對象、泛型等Java SE的基礎。 本書適用于以下讀者：希望進入互聯網公司工作的讀者、研究Netty底層知識的讀者、在工作中遇見瓶頸，希望通過學習Netty提升底層知識的讀者、從事開發高併發支撐中間件的讀者、從事互聯網高併發業務支撐的讀者、對多線程編程感興趣的讀者、希望通過Netty源碼找到調優點的讀者。

Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things.When you are born, the first thing you do is scream. Be it a response to fear, anger, sadness, or happiness, the scream is a declaration of being alive. The metal vocalist cupping the microphone blares out a deafeningly harsh scream. The drill instructor screams out commands to their soldiers. And then there’s the bloodcurdling screams we know from horror films. A scream has many meanings, but it is an instinctive and reflexive action that, at its core, reveals raw emotion.Investigating popular and alternative cultures, art, and science, Michael J. Seidlinger tracks the resonance of the scream across media and literature and in his own voice. Object Lessons is published in partnership with an essay series in The Atlantic .

Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things.What can underground pipes tell us about human eating habits and the spread or containment of disease, such as COVID-19? Why are sewers spitting out plastic and trash into waterways around the world? How are clogs getting gnarlier and more numerous? Jessica Leigh Hester leads readers through the past, present, and future of the system humans have created to deal with our own waste and argues that sewers can be seen as a mirror to the world above at a time when our behaviors are drastically reshaping the environment for the worse. Sifting through the muck offers a fresh way to approach questions about urbanization, public health, infrastructure, ecology, sustainability, and consumerism― and what we value. Without understanding sewers, any attempt to steward the future is incomplete. Object Lessons is published in partnership with an essay series in The Atlantic .

Bullshit isn't what it used to be. Now, two science professors give us the tools to dismantle misinformation and think clearly in a world of fake news and bad data. "A modern classic . . . a straight-talking survival guide to the mean streets of a dying democracy and a global pandemic."--Wired Misinformation, disinformation, and fake news abound and it's increasingly difficult to know what's true. Our media environment has become hyperpartisan. Science is conducted by press release. Startup culture elevates bullshit to high art. We are fairly well equipped to spot the sort of old-school bullshit that is based in fancy rhetoric and weasel words, but most of us don't feel qualified to challenge the avalanche of new-school bullshit presented in the language of math, science, or statistics. In Calling Bullshit, Professors Carl Bergstrom and Jevin West give us a set of powerful tools to cut through the most intimidating data. You don't need a lot of technical expertise to call out problems

'This marvellous book will transform your relationship with the numbers that swirl all around us' TIM HARFORD, author of The Undercover EconomistStatistics has played a leading role in our scientific understanding of the world for centuries, yet we are all familiar with the way statistical claims can be sensationalised, particularly in the media. In the age of big data, as data science becomes established as a discipline, a basic grasp of statistical literacy is more important than ever. In The Art of Statistics, David Spiegelhalter guides the reader through the essential principles we need in order to derive knowledge from data.Drawing on real world problems to introduce conceptual issues, he shows us how statistics can help us determine the luckiest passenger on the Titanic, whether serial killer Harold Shipman could have been caught earlier, and if screening for ovarian cancer is beneficial. How many trees are there on the planet? Do busier hospitals have higher survival rates? Why
