问题 In my Mojolicious perl code I handle a jobs created and watched from a remote client. I keep the jobs in a array of hashes, which is a global variable. It is then used in handlers of PUT '/job/create' and GET '/job/status'. When adding a new job with the PUT '/job/create' the array gets extended in the subroutine (it contains 4 elements in the code below), but when requesting the jobs' status via GET '/job/status' the list of jobs, the array does not contain the added elements (it counts 2

TypeScript 的两种声明文件写法的区别和根本意义

阅读更多关于 TypeScript 的两种声明文件写法的区别和根本意义

作者: Angus.Fenying < i.am.x.fenying@gmail.com > 日期: 2016-09-15 05:40 PM 我们知道 NPM 包可以有内建的 TS 声明文件，从而免去使用 typings 工具安装 TS 声明文件的操作。那既然可以有内建的声明文件，为何还需要额外安装呢？因为不是所有人都在使用 TypeScript，很多 NPM 模块都是纯 JavaScript 编写的，其作者没有太大的可能性为之编写模块声明文件。而且内建的声明文件有一定约束。 TypeScript 的 DefinitelyTyped 声明文件有两种写法，一种叫做全局类型声明(Global Type Definition) ，另一个则是叫做模块导出声明(External Module Definition) 。 External Module 一词源自 TypeScript 1.5 之前的内部模块/外部模块之说，而 1.5 之后内部模块变成了 namespace，外部模块直接化为模块，不再有内外部模块之说。所以这里将 External Module Definition 译为模块导出声明比较合适。 DefinitelyTyped 对此的说明是：如果你的模块需要将新的名称引入全局命名空间，那么就应该使用全局声明。如果你的模块无需将新的名称引入全局命名空间

What is the most “elegant” way to define a global constant array in PHP

阅读更多关于 What is the most “elegant” way to define a global constant array in PHP

问题 I was wondering what do you think would be the best and cleanest way to define a constant array variable similar to the way define function works. I've seen a lot of people asking this question in Google and so far the easiest solution I have come up with is to use the PHP serialize function inside the define statement, like this define ("MY_ARRAY", serialize (array ("key1" => $value1,"key2" => $value2, ..))); then to use the defined constant you can do something like this: $MY_ARRAY =

How do I create a Solution Wide Connection String

阅读更多关于 How do I create a Solution Wide Connection String

问题 Does anyone know if it is possible to create a single connection string that will be accessible to all the projects in a solution (we have about 6). I can create a text file with this information, but we need design time support as well, and it is not practical to have a connection string in every App.Config and Web.config file in the solution. We basically want a Single connection string that is easy to change should the location of the db change, that will also be used by the IDE for design

问题 I'm trying to get the wheels turning on a large project in C#. My previous experience is in Delphi, where by default every form was created at applicaton startup and form references where held in (gasp) global variables. So I'm trying to adapt my thinking to a 100% object oriented environment, and my head is spinning just a little. My app will have a large collection of classes Most of these classes will only really need one instance. So I was thinking: static classes. I'm not really sure why
