程序员的 工具箱

掌握/需要/提供的 不同种类技术 更有逼格的一种说法。

一般来说是指将N种技术互相组合在一起(N>1)，作为一个有机的整体来实现某种目的。也可以指掌握这些技术以及配合使用的经验。

打比方说LAMP LNMP MEAN都是常见的web技术栈

这里的栈就是英文的stack的意思（一些东西堆在一起），而非数据结构的栈的意思

这听起来就像是一个外来语：

A technology stack comprises the layers of components or services that are used to provide a software solution or application. Traditional examples include the OSI seven-layer model, the TCP/IP model, and the W3C technology stack.
Technology stacks are often articulated as a list of technologies, such as "J2EE with Java Server Faces running against a SQL Server database" or as a diagram.
-Wikipedia

比如stackoverflow里面的一个回答 What technology stack to choose ：

• Java (cross-platform)
• JSF for the presentation layer. JSF is more or less similar to ASP.NET, (and Java and C# are also alike), so the .NET background wouldn't be such a problem.
• Hibernate / JPA (powerful, multiple database support)
• Selenium, JSFUnit, JUnit, TestNG for testing
• Eclipse + plugins - mostly free
• PostgreSQL - powerful and free
• Some Linux distribution for OS
• spring framework - you don't have any specific requirement for this, but it makes your life easier.

这看起来，额，像是个栈，可惜它不是后进先出的。
口胡，这种数据结构，明明是技术树或者技术图哇！
