A resignation is the formal act of giving up or quitting one’s office or position. A resignation can occur when a person holding a position gained by election or appointment steps down, but leaving a position upon the expiration of a term is not considered resignation. – Wikipedia
PS: I’ve quit my job now, feel free to contact me.

你和你的工作 || 酷 壳 - CoolShell
我的观点的,先别否定他的观点,试着去理解一下为什么他要这么说,你会发现还有一些道理的。然后,想一想,自己需要的是什么?一份工作?还是一份经历?还是不断的自我挑战?相信你会有知道该怎么去做的。当然,“离职”是最后一步棋,在此前,我更希望你能尝试地在你现在工作环境下去改变去影响。 如果你对你的工作不高兴——离开,如果每天早上你对你的工作没有激情——无论你在干什么你都要停下来。

三个事和三个问题 || 酷 壳 - CoolShell
其实,我还有很多故事可以讲,只不过我写得太多了,差不多到文章该结束的时候了。那些事改天再说吧。我经历的这些事让我思考了很多很多。每年年底都是我情绪比较低沉的时候,因为,这个时候是我反思一年中的得失的时候,在这个时间段里,我会有一些不安,那种我害怕已经虚度了这一年的那种不安。 2011年的年底,我问了我自己三个问题:
- 1)每天早上醒过来的时候,我会为什么感到兴奋?是什么在驱动着我去开始新的一天?
- 2)现在的经历有没有让我有这种兴奋的感觉?这种让我充满力量和期待的感觉?
- 3)有没有浮燥,有没有得到认可?身边的人的认可?但更重要的是自己是否对自己认可?
我把我自己的这三个问题共享给大家,我有我的答案,相信你也有你的答案。

技术人员的发展之路 || 酷 壳 - CoolShell
无论是在职场中打拼,还是追求精彩的经历,还是去实现自由,我觉得都是不错的个人发展的方向。
总之,这里的逻辑是——
- 能够去规划自己的个人发展的人,通常都是有很多机会和可能性的人。
- 有很多机会和可能性的人,通常都是有Leadership,喜欢冒险的人。
- 有Leadership喜欢冒险的人,通常都是学习能力强,思维活跃,喜欢折腾,懂得“投资”的人。
- 学习能力强思维活跃的人,通常来说,都是喜欢看书,喜欢实践和新鲜事物,不怕艰难和挑战,用智力而不是使蛮力的人。
- 懂得“投资”的人,通常来说,他们更多的关注的是未来和长远的成长,而不是当下的KPI、奖金和晋升。

Man, ‘splained: 40-Plus Years of Man Page History — Truss
The history of man pages is tied inextricably to the history of Unix
(in fact, they share a birthday) and is threaded through a certain
formative era of computer science. Man pages go back to Bell Labs, back to
Jerry Saltzer’s doctoral thesis proposal in 1964, back to decisions that
were made without the intention of determining the way certain areas of
programming would work for decades. And maybe that’s the biggest lesson of
this whole story: never treat a solution as a stopgap or a prototype
(particularly if you’re working in Bell Labs in the late 60s or early 70s).
Your “This’ll do for today” could become the standard for the generations
to follow.

WebSocket Demystified
WebSocket enables bidirectional, message-oriented streaming of text and binary data between client and server. It is the closest API to a raw network socket in the browser. Except a WebSocket connection is also much more than a network socket, as the browser abstracts all the complexity behind a simple API and provides a number of additional services:
- Connection negotiation and same-origin policy enforcement
- Interoperability with existing HTTP infrastructure
- Message-oriented communication and efficient message framing
- Subprotocol negotiation and extensibility
A comprehensive guide about WebSocket, including WebSocket API、Protocol、Use cases and Performance.

CDN的原理以及其中的一些技术
CDN,全称Content Delivery Network,主要作用是为源站减少访问压力的同时,为客户端提供更快速的内容响应。除此之外,CDN还能对源站进行安全防护。 其实真正为CDN付费的是源站,所以CDN的用户其实是源站,例如新浪微博,youku视频,淘宝网啊之类的。而客户端,是CDN的用户的用户。

100 more of those BITFIELDs - <antirez>
The essence of this command is not new, it was proposed in the past by me and others, but never in a serious way, the idea always looked a bit strange. We already have bit operations in Redis: certain users love it, it’s a good way to represent a lot of data in a compact way. However so far we handle each bit separately, setting, testing, getting bits, counting all the bits that are set in a range, and so forth.

A Brief Introduction to Apache Cassandra | DataStax Academy
The article provides an overview of non-relational databases and Apache Cassandra™, and describes a number of top-level Cassandra concepts that will help you understand how it operates and manages data. Subsequent ebooks in this series will expand on the material provided here, providing you with all the information necessary to build successful online applications that use Cassandra as the underlying data store. If you are new to Cassandra, then what follows should greatly help you understand what it’s all about.

Exponential Backoff And Jitter
While OCC is guaranteed to make progress, it can still perform quite poorly under high contention. The simplest of these contention cases is when a whole lot of clients start at the same time, and try to update the same database row. With one client guaranteed to succeed every round, the time to complete all the updates grows linearly with contention.
The problem here is that N clients compete in the first round, N-1 in the second round, and so on. Having every client compete in every round is wasteful. Slowing clients down may help, and the classic way to slow clients down is capped exponential backoff. Capped exponential backoff means that clients multiply their backoff by a constant after each attempt, up to some maximum value.

How We Built r/Place – Upvoted
Each year for April Fools’, rather than a prank, we like to create a project that explores the way that humans interact at large scales. This year we came up with Place, a collaborative canvas on which a single user could only place a single tile every five minutes. This limitation de-emphasized the importance of the individual and necessitated the collaboration of many users in order to achieve complex creations. Each tile placed was relayed to observers in real-time. Multiple engineering teams (frontend, backend, mobile) worked on the project and most of it was built using existing technology at Reddit. This post details how we approached building Place from a technical perspective. 本文从技术角度讲解 Reddit 是如何构建 r/Place 的:面对要解决的诸多问题,他们逐步分析、权衡取舍,最终成功地支持了今年愚人节的实验和创举。 要回顾 r/Place,可以看看霍炬的两篇文章。作者亲历 Reddit 的『像素大战』,详述了游戏的经历和感受,内容十分有趣。
