最近的项目在用maven 进行install的时候，发现老师在控制台输出警告：[WARNING] Using platform encoding (UTF-8 actually) to copy filtered resources, i.e. build is platform dependent!虽然并不影响项目的正常运行和install,但是对于处女座的我来说一点都不想看到这警告的发生。所以就研究了一下，找到解决办法，现在分享给大家。
当你试图在构建为社区带来大量价值的开源工具和经营成功的商业业务之间把握好界限时，你必须把很多事情做好。在“致力于原生云”播客的第七集中，我们与 Richard Li 进行了交谈，他与 Ambassador Labs 成功地完成了这一工作。我们从这次谈话中学到了很多，我们认为你们也会的。
本文通过创建几个类来覆盖python中类的基础知识，主要有如下几个类 Animal ：各种属性、方法以及属性的修改 Dog ：将方法转化为属性并操作的方法 Cat ：私人属性讲解，方法的继承与覆盖 Tiger ：子类定义时调用父类方法（super的使用） Animal python中的一个类中有属性和方法，而二者都分为很多种类型，如下所示 属性分为普通属性和类属性 方法分为普通方法、类方法、静态方法。 具体定义方法和使用见下面的代码和注释，各个属性和方法的使用习惯等见最后的 print_animal 函数打
父类的构造函数总是在子类之前执行的。既先初始化静态构造函数，后初始化子类构造函数。
Not all memory allocated in the virtual memory space is the same. We can classify it through two axis: the first axis is whether memory is private (specific to that process) or shared, the second axis is whether the memory is file-backed or not (in which case it is said the be anonymous). This creates a classification with 4 memory classes:

Agile software development is a set of management framework and practices to develop high quality product and deliver the set of features in software which are actually needed by the users. The product development lifecycle is full of pivotal points according to which you have to keep on modifying the product according to user’s demand and interaction behavior with the software. The earlier models were not capable to observe required changes at early stage and adapting the changes to make the product a better market fit.

CSS variables are always a hot topic when “the future of CSS” is discussed. They are actually comingnatively, but using them in production (without a CSS preprocessor framework) is a long way off. However there is a feature that actually has some browser support now that has a CSS variable feel to it, and that’s the currentColor value.
当我们历尽千辛万苦，终于训练出来一个模型时，想不想将这个模型发布出去，让更多人的受益？
在系统开发过程中，需要对数据进行查询，大部分情况下从数据库中查询的数据量比较大，在系统页面无法全部显示，而且查询全部的数据会影响系统的反应速度，需要对所查询的数据进行分页的查询操作，以此减轻系统的压力。在Oracle数据库中，如何完成分页SQL的编写，影响着系统开发的速度，特提供两个SQL的分页模板：采用oracle的内置函数ROWNUM。（ROWNUM是结果的伪列，仅仅当聚集结果时产生，但早于排序或聚合）采用oracle的内置函数ROW_NUMBER。在数据库之外的分页之中，应用层缓存技术分页不可避免地产生大量的网络流量；游标驱动分页在数据库里完成操作，会受到游标技术的影响，使得分页变得“陈旧”。

TensorFlow 1.x is primarily a framework for working with static computational graphs. Nodes in the computational graph are Tensors which will hold n-dimensional arrays when the graph is run; edges in the graph represent functions that will operate on Tensors when the graph is run to actually perform useful computation.

Just received my results this morning and thought I will share my experience with those who are working towards architect certification. Score Grade: P Score: 95 Class Diagram (44 maximum) .......................... 39 Component Diagram (44 maximum) ...................... 44 Sequence/Colloboration Diagrams (12 maximum) ........ 12 My Submission: 1) One main Class diagram (25-30 classes/interfaces)which was an extension of the BDM. Besides domain entity objects, I only included objects that will handle the workflow. Diagram showed relationships (both association and aggregation), dependencies and only attribute/methods that I thought would improve clarity. I actually changed the BDM to what I thought was more logical, but I documented this down. 2) One Class diagram to show relationship between Controller/Views for the system, and how session for both Travel Agent and web client will be addressed. 3) Four component diagrams for each of the use case specified in the assignment 4) Five sequence diagrams to cover the 4 use case specified in the assignment (I had 2 diagrams for Pay Itinerary - one for Payment with credit card and one for mileage redemption) 5) 9 pages (printed HTML pages) to document:

字符串是非常好用的东西，所以在这个练习中你将学会如何创建包含变量内容的字符串，并使用专门的格式化(format string)和语法把变量的内容放到字符串里，相当于告诉python：“这是一个格式化字符串，把这些变量放到指定的位置!”
修改first-sub-module/sub-sub-module/pom.xml
Problem Description Roy has just moved into a new apartment. Well, actually the apartment itself is not very new, even dating back to the days before people had electricity in their houses. Because of this, Roy’s apartment has only one single wall outlet, so Roy can only power one of his electrical appliances at a time. Roy likes to watch TV as he works on his computer, and to listen to his HiFi system (on high volume) while he vacuums, so using just the single outlet is not an option. Actually, he wants to have all his appliances connected to a powered outlet, all the time. The answer, of course, is power strips, and Roy has some old ones that he used in his old apartment. However, that apartment had many more wall outlets, so he is not sure whether his power strips will provide him with enough outlets now. Your task is to help Roy compute how many appliances he can provide with electricity, given a set of power strips. Note that without any power strips, Roy can power one single appliance through the wall outlet. Also, remember that a power strip has to be powered itself to be of any use.
