throttles
Throttle原本的意思是节流阀或者油门，用于控制流体（如汽油、空气）流动的速度或量。在汽车中，踩油门就是通过控制油门来增加燃油流向引擎的速度，从而加快车速。在计算机科学（CS）中，"throttle"这个概念被借用来表示限制或控制数据传输或处理的速率。这种概念转移是因为在两个领域中，throttle都涉及到通过调节流量来达到控制系统行为的目的。
在Alertmanager的上下文中，throttle意味着控制警报通知的发送频率，以避免过多的通知造成接收者或者系统的负担。例如，如果有大量相似的警报被触发，而不加以控制地发送所有通知，那么接收方（比如运维团队）可能会被大量重复的信息淹没，从而难以迅速准确地响应真正重要的警报。通过throttling，Alertmanager可以合理地控制通知的发送，确保信息的有效传达而不造成不必要的干扰。

binary
在这个上下文中，"a binary"指的是一个可执行文件，也就是一个编译好的程序，可以直接在计算机上运行。它被称为"binary"是因为它以二进制格式存储，这是计算机能够直接理解和执行的格式。所以，虽然"binary"确实有二进制的意思，但在软件和编程领域，提到"a binary"时，通常是指一个编译后的可执行程序。

Typescript is great compared to plain JS, but they're really deep into diminishing returns area with type system features for a couple of years now.A lot less would be a lot more, because as of now Typescript lures otherwise entirely competent programmers into writing complex 'type system puzzles' which are entirely obscure to everybody except the person who wrote that code, and it takes a lot of discipline and experience to reist the lure and keep things simple.

Siemens (2002) notes that learner-learner interactions in an e-learning course can be viewed as a four stage continuum:
Communication People ‘talking,’ discussing Collaboration People sharing ideas and working together (occasionally sharing resources) in a loose environment Cooperation People doing things together, but each with his or her own purpose Community People striving for a common purpose

In general, if μ\mu is an invariant map, then any transition τ=(ℓ,ℓ′,ρ)\tau=(\ell, \ell^{\prime}, \rho) can be safely strengthened by replacing the transition relation ρ\rho by μ(ℓ)∧ρ\mu(\ell)\wedge\rho.
这是比较常见的用不变式增强转移关系的方法。

Internet Reciprocal Teaching Promotes the Five CsCreativity: Students use divergent-thinking skills to generate their own questions and keywords for online searches. Their final projects require them to creatively express their own point of view. Communication: Students share what they learn as they work in small groups and with the whole class. They communicate with a wider audience by posting on a class blog. Collaboration: Students create collaborative knowledge through Internet inquiry and social interactions. They comment on one another's work using technologies such as VoiceThread and support one another through instant messaging. Critical Thinking: When using the Internet, students build the text they read, choosing which links to follow and which to ignore. The nonlinear nature of online reading helps support critical thinking. Students also learn to question the perspective and bias of online sources. Comprehension: Students learn important online reading skills, such as how to distinguish news articles from blog posts and editorials. They carefully read texts they encounter online to understand and evaluate different perspectives.

By "augmenting human intellect" we mean increasing the capability of a man to approach a complex problem situation, to gain comprehension to suit his particular needs, and to derive solutions to problems.

This means they have some say – although not complete – over their personal data, and in turn they begin to have an understanding of the technologies that underpin the Web, including how their work and their data circulate there.
You know, if we're going to force Gen Ed material down student's throats and wallets, why not throw in IT/CS stuff while we're at it? Technical literacy would make for a fair easier world.

In Python, as well as in any other object-oriented programming language, we define a class to be a description of what the data look like (the state) and what the data can do (the behavior). Classes are analogous to abstract data types because a user of a class only sees the state and behavior of a data item. Data items are called objects in the object-oriented paradigm. An object is an instance of a class.
Class = General description of form and functions of data. Object = A member or instance of a class.
