A few years back, some tech bloggers bemoaned the lack of experienced RPG programmers. They claimed that IBM i programmers were aging out with the system. In response, others said, “There’s no lack of iSeries RPG Developers.” IBM might be “old,” but it’s one of the most used and reliable systems in business.
Deon用半开玩笑的方式,分享了他认为“怎样才是一个好的程序员”。 “我一直在跟我认为很棒的程序员们一起工作,可是他们真的很好吗?他们怎么做到这么好的?(或者,他们水平也是一般而已?)” I recently read a blog post by Mark Pearl titled “Programming, a Subset of Writing.” As much as I agree with the underlying message of this post, something really
支持 field 类型的修改. 支持快捷键打开 GsonFormat ,默认为 option+s(mac), alt+s(win) 支持 field 名称的修改. 支持添加 field 前缀. 支持多种转换库 (Gson,Jackjson,FastJson,LoganSquare). 支持 private 和 public 两种模式. 支持过滤父类已有属性.
In this article, I’ll share 11 skills, which I believe, every programmer should know or learn in 2020.
关于程序员有没有必要记一些API什么的讨论有很多,我个人觉得能Google到的就没必要刻意去记,可以简单的做个笔记,需要用的时候查一下就好了。真正有必要记的东西,用得多了自然也就能记住了。 文章不难,不浪费时间翻译了。原文链接

要使程序可以运行必须引入JSON-lib包——org.json.jar包。综合来看,这个JAR包比较好用。
简 单地说,JSON 可以将 JavaScript 对象中表示的一组数据转换为字符串,然后就可以在函数之间轻松地传递这个字符串,或者在异步应用程序中将字符串从 Web 客户机传递给服务器端程序。这个字符串看起来有点儿古怪(稍后会看到几个示例),但是 JavaScript 很容易解释它,而且 JSON 可以表示比名称/值对更复杂的结构。例如,可以表示数组和复杂的对象,而不仅仅是键和值的简单列表。
1. “名称/值”对的集合(A collection of name/value pairs)。不同的语言中,它被理解为对象(object),记录(record),结构(struct),字典(dictionary),哈希表(hash table),有键列表(keyed list),或者关联数组 (associative array)。
Creative professionals and talented developers are key players for making a business successful. It is no surprise that hiring programmers is a complex process and a daunting task. It’s simply because it’s hard to find a company on which you can rely on.

2.简单文件输入/输出(读取文本文件) 对于文件读取,同样的,C++使用类似cin的东西。对于cin,需要包含iostream头文件,该文件定义了一个用于输入的istream类,并在该头文件中已经声明好了一个cin的istream变量(对象)。而在使用读取文件时,需要包含fstream头文件,该头文件定义了ifostream类,在使用的时候需要声明一个ifstream类,通过open()方法与文件关联起来,然后就可以像使用cin一样使用该ifstream,读取目标文件的内容。最后,使用close()方法将文件关闭。
因为json数据是原生态数据,因此这种数据格式很稳定,而且描述能力强,我们建议大家使用json格式
Lambda表达式的语法 基本语法: (parameters) -> expression 或 (parameters) ->{ statements; } 下面是Java lambda表达式的简单例子: [java] view plaincopy // 1. 不需要参数,返回值为 5 () -> 5 // 2. 接收一个参数(数字类型),返回其2倍的值 x -> 2 * x // 3. 接受2个参数(数字),并返回他们的差值 (x, y) -> x – y // 4. 接收2个in
.Net Framework has been probably the best advancement by Microsoft for web applications, work area applications and site improvement. .Net designers and individuals who have been in steady interface with this stage definitely realize that it has its own library of dialects, structure and further turns of events.

Job.com的联合创始人兼首席愿景官Arran Stewart告诉TechNewsWorld:“人工智能和区块链是IT领域的两个关键市场,预计将继续保持逐年增长。” 到2027年,人工智能的复合年均增长率(CAGR)预计将超过42%,而到2025年,区块链的复合年增长率将超过67%,这两个领域“代表了IT领域最大的增长领域,美国市值达到1万亿美元,”斯图尔特说。 他预测,在未来三年中,对数据科学家,程序员和区块链专业程序员的需求将会增加。 斯图尔特指出,其他领域是物流,尤其是在自动驾驶汽车和交付领域,这是由于对使用人工智能和机器学习来创新,改善和更新运输领域的投资增加了。 “金融技术(Fintech)和隐私向着区块链的未来也发生了很大的变化,因此这些行业在未来十年可能会吸收更多的人才。”
JSON(JavaScript Object Notation) 是一种轻量级的数据交换格式。JSON采用完全独立于语言的文本格式,这些特性使JSON成为理想的数据交换语言。易于人阅读和编写,同时也易于机器解析和生成。
Get在json中搜索指定的路径。路径用点语法表示,比如“name.last"或“age"。这个函数需要提供格式正规和有效的json值。无效的json不会引起panic,但它可能返回意外的结果。当找到值后立即返回。

枚举用来管理一组相关常量的集合,使用枚举可以提高程序的可读性,使代码更清晰且更易于维护。
Microsoft Foundation Classes (MFC) The C++ class library that Microsoft provides with its C++ compiler to assist programmers in creating Windows-based applications. MFC hides the fundamental Windows API in class hierarchies so that programmers can write a Windows-based application without needing to know the details of the native Windows API. Active Template Library (ATL) A C++ template library used to create ActiveX servers and other Component Object Model (COM) objects. ActiveX controls created with ATL are generally smaller and faster than those created with the Microsoft Foundation Classes. Component Object Model (COM) An open architecture for cross-platform development of client/server applications. It is based on object-oriented technology as agreed upon by Digital Equipment Corporation and Microsoft Corporation. COM defines the interface, similar to an abstract base class, IUnknown, from which all COM-compatible classes are derived.

IBM i has evolved overtime and organizations are modernizing their existing legacy systems to use the latest updates in IBM i. It is generally considered as old, obsolete and not trending just because it is in existence for 30 years. But replacing IBM i with some other technology is not worth it, instead IT teams must plan to modernize the existing IBM i systems of their organization. Now, modernizing is not as easy as it looks because the confusion here is which approach to choose among numerous options to update IBM i. The way you modernize your IBM I systems will decide the return you get after the updates. Some of the recommendations include unfolding the data and logic, improving the user interface and the software development process.

This reference manual describes the syntax and “core semantics” of the language. It is terse, but attempts to be exact and complete. The semantics of non-essential built-in object types and of the built-in functions and modules are described in The Python Standard Library. For an informal introduction to the language, see The Python Tutorial. For C or C++ programmers, two additional manuals exist:Extending and Embedding the Python Interpreter describes the high-level picture of how to write a Python extension module, and thePython/C API Reference Manual describes the interfaces available to C/C++ programmers in detail.
