问题 I have done this without kinetic.This piece of code is working fab as I wanted. --fiddle without kineticjs. Take a look Now I want to do the same code with kineticjs.

This is my javascript with kinetic.results cannot be seen in fiddle because there is no option for including kineticjs.though I have put my code up there

我花10个小时,写出了小白也能看懂的阿里数据中台分析

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 作者:数据分析不是个事儿 https://www.jianshu.com/p/05a8db84e454 数据中台被誉为大数据的下一站,由阿里兴起,核心思想是数据共享,2015年阿里提出“大中台,小前台”的策略。2018 年因为“腾讯数据中台论”,中台再度成为了人们谈论的焦点。 2019年,似乎人人都在提数据中台,但却不是所有人都清楚数据中台到底意味着什么。数据中台是只有大厂才需要考虑的高大上的概念吗?普通企业该不该做数据中台?数据中台的出现会给现有数据从业者们带来颠覆式的挑战吗? 数据中台不是大数据平台! 首先它不是一个平台,也不是一个系统,如果有厂商说他们有个数据中台卖给你,对不起,它是个骗子。 要回答数据中台是什么,首先要探讨一下中台到底是什么。虽然没有明确的定义,但是作为理工直男,我们可以先把中台看作是一种中间层。既然是一种中间层,那么中台确实是一种十足技术用语,我们可以完全从技术角度来探讨了。 我们可以应用 Gartner 的 Pace Layer 来理解为什么要有中间层,这样可以更好地理解中台的定位和价值。Pace Layer 里提到,可以按照事物变化的速度来分层,这样可以逐层分析并设计合理的边界与服务。 在数据开发中,核心数据模型的变化是相对缓慢的,同时,对数据进行维护的工作量也非常大

DDD: Should a Dto Assembler be a part of Domain Layer?

倖福魔咒の 提交于 2019-12-12 10:55:55
问题 Thanks in advance. I have some Aggregates in the Domain Layer library. Also, some DTO s in a separate library, which is shared between Server and Client side. An Aggregate of an entity is more informative than its DTO . So, in order to convert from DTO to Aggregate , a repository should be accessed by a Dto Assembler . Interfaces of repositories are in Domain Layer . That's why i come to conclusion that DtoAssembler should be a part of DomainLayer . Is this right? 回答1: No, this would be plain

问题 I have UiTableView within UiView . I want to set corner radius & shadow to UIView .

Pre-rendering, Pre-blending, CoreGraphics, CALayers?

别等时光非礼了梦想. 提交于 2019-12-12 06:06:24
问题 I have 200+ uiLabels added to a long (92000px) uiScrollView. I am getting the impression from some of the QAs that one option to improve performance is to pre-render the whole view into one? I basically add my uiLabels in a for loop inside ViewDidLoad to a scrollview. Could someone give me a few ideas for how you could go about rendering all those uilabels to a single layer? then add that layer to the uiScrollView? (I mention single Layer, I don't know anything about layers, I am just making

Leaflet: How to control opacity of Layer Groups?

余生颓废 提交于 2019-12-12 01:23:23
问题 Does some expert know how to change the opacity of each tilemap of a Layer Group by using a HTML-slider input? For example: I've got several tilemaps, which could be switched by using Lealet's Layercontrol button, like here: Leaflet Layer Groups. When using the opacity-slider I want to dim each tilemap, not just one being actually active. For example: I'm dimming map1 to 0.5 Then switching to map2, its opacity should already also be 0.5. And when changing the opacity of map2 to 0.8 with the

Table with div layers

和自甴很熟 提交于 2019-12-11 16:24:25
问题 I have a table inside a div 1. Then after that div 1 added another div 2 with position:relative; top:-250; so that div 2 layer will be right on top of the table. But now below the table there is a big space before anything on the page can resume displaying (I guess the second div 2 would have normally been without the -250 position change?) How do I get rid of the space and clear it? I tried this... <div style="clear:both;"></div> ...and it didn't do anything 回答1: Using absolute positioning

Nutiteq map freezing after adding a few lines and markers

霸气de小男生 提交于 2019-12-11 16:16:27
问题 im developing a traffic application and there is a few traffic lines and warning markers on the road. I draw traffic lines according to zoom level. For example, If zoom level is over 10, im removing all lines and redraw for new zoom level. Because lines overflow on the road. I have lines over 400 for every zoom level. So every zoom in/ zoom out action, i remove and redraw. After a while my map begins to freeze and moving very slowly. Is there any caching operation on background? Because im

Drastic slowdown using layer backed NSOpenGLView

一笑奈何 提交于 2019-12-11 12:59:14
问题 I needed to display some Cocoa widgets on top of an NSOpenGLView in an existing app. I followed the example in Apple's LayerBackedOpenGLView example code. The NSOpenGLView is given a backing layer using: [glView setWantsLayer:YES] Then the Cocoa NSView with the widgets is added as a subview of the glView . This is basically working and is twice ad fast as my previous approach where I added the NSView containing the widgets to a child window of the window containing the glView (this was the

Programmatically drawing polygons on a map by joining the outermost markers

只谈情不闲聊 提交于 2019-12-11 11:09:34
问题 I have a sample map layer in this fiddle where the map layer is drawn using fusion table as, var Layer = new google.maps.FusionTablesLayer({ query: { select: 'lat', from: '1BLPDF4n0sW0i0BfD9Yo0DqbshyTH1s5Iuu_1IeU' }, map: map, suppressInfoWindows: true }); How can I draw a polygon programmatically by joining the outermost markers in the map so that if someone add new marker and if it is falling outside the drawn polygon then automatically the polygon should redraw to include the newly added
