Earlier this week, we announced the Microsoft Supply Chain Platform. At the core of the Supply Chain Platform is the Microsoft Supply Chain Center, which introduces a ready-made command center for users to manage disparate supply chain data.

It has become clear that ESG environmental and social governance initiatives are becoming a top business priority for many organizations. The opportunity facing business leaders is to find ways to utilize technology to drive a positive impact on business performance and the well-being of society and the environment. In October, we launched the release wave 2—hundreds of new innovations across Microsoft Dynamics and Microsoft Power Platform, releasing between October and March Start reimagining your supply chain for a more agile, resilient future.

Register now for Supply Chain Reimagined on Wednesday, November 16, , from to AM Pacific Time UTC DEC began selling its first computer at the end of While continuing to release new PDPs into the market, DEC also charged forward in its delivery of new modules.

The Flip Chip came out in and was meant to convert the PDP-4 to the PDP Many of its subsequent module releases served a similar purpose: helping users convert their old computers to upgraded versions.

It was in this year when DEC released the PDP-8, which is widely recognized as the first successful commercial minicomputer. In the interim, DEC came up with a revamped version of their PDP line and released the PDP minicomputer. Not only did it bring major upgraded features to their computing machines, it also was easier to use. By the time it stopped selling it in the s, DEC sold over , of them, making it one of the most popular minicomputers ever.

In addition, the design of the computer, as well as its operating system, turned out to be immensely popular with other computing companies, that eventually ended up using it as inspiration for their own work. After widespread success with its PDP, DEC made the move into high-end computers and launched the Virtual Address eXtension, or VAX.

This new bit minicomputer or supermini line aimed to provide users with a wide array of computing resources that would be more affordable, powerful, and smaller than what companies like IBM could offer at the time.

DEC continued to stay busy during this time, regularly putting out new models of the VAX. The VAX came out in and became an instant bestseller. DEC was recognized as one of the premier leaders in computing when it was named the second largest computer company, just behind IBM.

DEC released Alpha AXP, which was a bit microprocessor created to solve the overly complicated circuit designs of its VAX computers and to ultimately speed up processing times. DEC launched AltaVista, one of the first ever search engines for the Internet. It became incredibly popular with users. 原创 Python量化交易实战教程汇总 B站配套视频教程观看设计适合自己并能适应市场的交易策略，才是量化交易的灵魂课程亲手带你设计并实现两种交易策略，快速培养你的策略思维能力择时策略：通过这个策略学会如何利用均线，创建择时策略，优化股票买入卖出的时间点。选股策略：掌握选股策略的核心逻辑，并基于收益率创建动量选股策略，并验证其有效性。手把手带你打造一个易扩展、更安全、效率更高的量化交易系统第三方平台大而全，不易扩展，效率还差，信息安全也是大问题，打造自己的交易平台才是更优解所有文章目录Python量化交易实战双均线策略股 原创 Js逆向教程AST Babel插件最简单修改值示例 最后的最后由本人水平所限，难免有错误以及不足之处， 屏幕前的靓仔靓女们 如有发现，恳请指出！你轻轻地点了个赞，那将在我的心里世界增添一颗明亮而耀眼的星！ 原创 Js逆向教程vscode无环境联调 最后的最后由本人水平所限，难免有错误以及不足之处， 屏幕前的靓仔靓女们 如有发现，恳请指出！你轻轻地点了个赞，那将在我的心里世界增添一颗明亮而耀眼的星！ 原创 Js逆向教程Hook基础 Hook就是在这些流程任意环节插入自己的代码，让浏览器先执行自己的代码 然后再执行原本网站的hook在以下流程中可以做的事情：hook在以下流程中可以做的事情上下文:表示一个环境（js上下文就是v8引擎，浏览器是不同的页签就是不同的上下文，js中的eval还是在一个上下文。只是虚拟机、）作用域:控制变量所生效的位置。作用域是更小的一个级别 处于上下文中结果如下：解释器是如何处理这段代码：首先解释器知道var xuhss在内存中声明了一个全局变量数组保存了xuhss，以后用的话，就到这个数组中找。如果数 php请求 原创 Js逆向教程websocket介绍 Ws和Wss的区别相当于http和https的区别，如果你想写一个聊天页面，需要频繁请求后台接口 还需要设置间隔时间（每隔1s发送一个请求） 才能拿到后台服务器的数据，因为http是轮询方式，只有请求完成后，才能拿到结果，只有客户端能发请求，所以说 要轮询。缺点就是占用服务器的性能？更好的方案就是websocket，它是浏览器实现的。浏览器在底层升级http协议，从http协议升级到websocket只需要添加几个头部信息就可以完成升级。 1.

Copyright © W3C ® MIT , ERCIM , Keio , Beihang.

W3C liability , trademark and document use rules apply. This document defines constructor functions, operators, and functions on the datatypes defined in [XML Schema Part 2: Datatypes Second Edition] and the datatypes defined in [XQuery and XPath Data Model XDM 3.

It also defines functions and operators on nodes and node sequences as defined in the [XQuery and XPath Data Model XDM 3. These functions and operators are defined for use in [XML Path Language XPath 3. At the time of writing, XSLT 3. It also replicates some of the functions defined herein, notably those concerned with processing of maps, so that these functions are available in XSLT 3. This is the fourth version of the specification of this function library. The first version was included as an intrinsic part of the [XML Path Language XPath Version 1.

The second version was published under the title XQuery 1. The third version, published on 8 April , was the first to carry its own version number, 3. This version 3. A summary of changes since version 3. This section describes the status of this document at the time of its publication.

Other documents may supersede this document. This document is governed by the 1 March W3C Process Document. This is a Recommendation of the W3C. This document was published by the W3C XML Query Working Group and the W3C XSLT Working Group , each of which is part of the XML Activity.

This publication differs from its version 3. There are numerous smaller differences as well, all documented in the change log. This specification is designed to be referenced normatively from other specifications defining a host language for it; it is not intended to be implemented outside a host language. The implementability of this specification has been tested in the context of its normative inclusion in host languages defined by the XQuery 3.

This document incorporates minor changes made against the Proposed Recommendation of 17 January Changes to this document since the Proposed Recommendation are detailed in F. Please use multiple Bugzilla entries or, if necessary, multiple email messages if you have more than one comment to make.

The purpose of this document is to catalog the functions and operators required for XPath 3. The exact syntax used to call these functions and operators is specified in [XML Path Language XPath 3. General purpose functions, available for direct use in user-written queries, stylesheets, and XPath expressions, whose arguments and results are values defined by the [XQuery and XPath Data Model XDM 3.

Constructor functions, used for creating instances of a datatype from values of in general a different datatype. These functions are also available for general use; they are named after the datatype that they return, and they always take a single argument. Functions that specify the semantics of operators defined in [XML Path Language XPath 3.

These exist for specification purposes only, and are not intended for direct calling from user-written code. This document defines functions and operations on these datatypes as well as the other types for example, nodes and sequences of nodes defined in Section 2. These functions and operations are available for use in [XML Path Language XPath 3. In particular, they may be referenced in future versions of XSLT and related XML standards. It introduces a new derived type xs:dateTimeStamp , and it incorporates as built-in types the two types xs:yearMonthDuration and xs:dayTimeDuration which were previously XDM additions to the type system.

In addition, XSD 1. Implementations of this specification may support either XSD 1. References to specific sections of some of the above documents are indicated by cross-document links in this document. Each such link consists of a pointer to a specific section followed a superscript specifying the linked document.

The superscripts have the following meanings: 'XQ' [XQuery 3. This recommendation contains a set of function specifications. It defines conformance at the level of individual functions. An implementation of a function conforms to a function specification in this recommendation if all the following conditions are satisfied:.

For all combinations of valid inputs to the function both explicit arguments and implicit context dependencies , the result of the function meets the mandatory requirements of this specification. For all invalid inputs to the function, the implementation signals in some way appropriate to the calling environment that a dynamic error has occurred. For a sequence of calls within the same · execution scope · , the requirements of this recommendation regarding the · determinism · of results are satisfied see 1.

Mechanisms for invoking functions, supplying arguments, initializing the static and dynamic context, receiving results, and handling errors;. A concrete realization of concepts such as · execution scope · ;.

Which versions of other specifications referenced herein for example, XML, XSD, or Unicode are to be used. Any behavior that is discretionary implementation-defined or implementation-dependent in this specification may be constrained by a host language.

Adding such constraints in a host language, however, is discouraged because it makes it difficult to re-use implementations of the function library across host languages. This specification allows flexibility in the choice of versions of specifications on which it depends:.

It is · implementation-defined · which version of Unicode is supported, but it is recommended that the most recent version of Unicode be used. It is · implementation-defined · whether the type system is based on XML Schema 1. It is · implementation-defined · whether definitions that rely on XML for example, the set of valid XML characters should use the definitions in XML 1.

The XML Schema 1. Furthermore, XSD 1. In this document, text labeled as an example or as a Note is provided for explanatory purposes and is not normative. The functions and operators defined in this document are contained in one of several namespaces see [Namespaces in XML] and referenced using an xs:QName.

This document uses conventional prefixes to refer to these namespaces. User-written applications can choose a different prefix to refer to the namespace, so long as it is bound to the correct URI. The host language may also define a default namespace for function calls, in which case function names in that namespace need not be prefixed at all.

The section 18 Constructor functions defines constructor functions for the built-in datatypes defined in [XML Schema Part 2: Datatypes Second Edition] and in Section 2.

The namespace prefix used in this document for most functions that are available to users is fn. This namespace is used for some mathematical functions. The namespace prefix used in this document for these functions is math. These functions are available to users in exactly the same way as those in the fn namespace. This namespace is used for some functions that manipulate maps see The namespace prefix used in this document for these functions is map.

The namespace prefix used in this document for these functions is array. This namespace prefix is not predeclared and its use in this document is not normative. There are no functions in this namespace: it is used for serialization parameters, as described in [XSLT and XQuery Serialization 3.

Functions defined with the op prefix are described here to underpin the definitions of the operators in [XML Path Language XPath 3. These functions are not available directly to users, and there is no requirement that implementations should actually provide these functions.

For this reason, no namespace is associated with the op prefix. The above namespace URIs are not expected to change from one version of this document to another. The contents of these namespaces may be extended to allow additional functions and errors, and serialization parameters to be defined. A function is uniquely defined by its name and arity number of arguments ; it is therefore not possible to have two different functions that have the same name and arity, but different types in their signature.

That is, function overloading in this sense of the term is not permitted. Consequently, functions such as fn:string which accept arguments of many different types have a signature that defines a very general argument type, in this case item? which accepts any single item; supplying an inappropriate item such as a function item causes a dynamic error.

Some functions on numeric types include the type xs:numeric in their signature as an argument or result type. In this version of the specification, xs:numeric has been redefined as a built-in union type representing the union of xs:decimal , xs:float , xs:double and thus automatically accepting types derived from these, including xs:integer.

It is possible for two functions to have the same name provided they have different arity number of arguments. For the functions defined in this specification, where two functions have the same name and different arity, they also have closely related behavior, so they are defined in the same section of this document. Each function or group of functions having the same name is defined in this specification using a standard proforma.

The function name is a QName as defined in [XML Schema Part 2: Datatypes Second Edition] and must adhere to its syntactic conventions.

Following the precedent set by [XML Path Language XPath Version 1.

The error is always classified as a dynamic error, even if the error code used is one that is normally used for static errors or type errors. Try it free 12 Learn more about Apple TV Plus.
