Acoording to the spec , the composition of an acrylic layer is: So I went to try a CSS-only approach inspired by the layers in that picture, this way: body { margin: 0; font: 1em/1.4 Sans-serif; background: url("http://www.wallpapers-web.com/data/out/191/5484624-sunset-wallpapers.jpg") center center; background-size: 100vw auto; } main { display: flex;

My network drive every hour sends to Google Drive packed 7z of a database file named: DATABASENAME_01.09.2017_07.bak.7z and in general the format: DATABASENAME_DD.MM.RRRR_HH.bak.7z The files on Google Drive are copied directly (I do not have any folders). I would like the files to be deleted instead of being moved to the trash. It's about releasing space. I wanted to employ other solutions described on Stackoverflow, but

However, I need a function to return an actual ".png" image so that I can call it with my HTML. Some more (possibly unnecessary) info: I am using Python Flask. I figure I could use fig.savefig() and just stick the figure in my static folder and then call it from my HTML, but I'd rather not do that every time. It would be optimal if I could just create the figure, make an image out of it, return that image, and

I want to use "-print-after-all", "-print-before-all", "-debug-only" ... without having to use the .bc file in between. 回答1: Additional arguments can be passed to LLVM's option parser with -mllvm . For your scenario this would look something like this: clang [...] -mllvm -print-after-all 文章来源: Is it possible to run clang with llc flags

介绍： flask-socketio模块实际上是封装了flask对websocket的支持，websocket在连接建立阶段是通过HTTP的握手方式进行的，这可以看做是为了兼容浏览器或者使用一些现成的功能来实现，这样一种捷径。当连接建立之后，客户端和服务端之间就不再进行HTTP通信了，所有信息交互都由websocket接管。Flask-SocketIO使Flask应用程序可以访问客户端和服务器之间的低延迟双向通信，使客户端建立与服务器的永久连接。 适用的场景： 后台产生新的数据，需要在前台页面马上展示出来，例如数据监控、统计图实时变化更新等。 当然，我们可以使用ajax来完成，通过ajax使得前台定时去后台索要数据，但如果消息频繁，ajax需要不断的建立和释放连接，效果明显不如后端直接推送数据到前台更加合适。 Flask-SocketIO的使用 首先安装依赖： pip install flask-socketio 一个简单的示例 （对Flask代码加了一层包装）： from flask import Flask, render_template from flask_socketio import SocketIO app = Flask(__name__) app.config['SECRET_KEY'] = 'secret!' socketio = SocketIO(app)

导读 CDH除了能够管理自生所提供的一些大数据相关服务外，还允许将第三方服务添加到CDH集群（托管在CDH上）。你需要做的就是按照一定的规则流程制作相关程序包，最后发布到CDH上。虽然过程并不困难，但是手动操作尤其是一些关键配置容易出错，往往导致最终服务无法正常在CDH上安装运行。 本文就是指导大家如何打包自己的服务，发布到CDH上，并且由CDH控制服务的运行、监控服务的基本运行状态。 相关介绍 名词介绍 (1)parcel : 以".parcel"结尾的压缩文件。parcel包内共两个目录，其中lib包含了服务组件，meta包含一个重要的描述性文件parcel.json，这个文件记录了服务的信息，如版本、所属用户、适用的CDH平台版本等。 命名规则必须如下 ： 文件名称格式为三段，第一段是包名，第二段是版本号，第三段是运行平台。 例如：FLINK-1.9.0-bin-scala_2.12-el7.parcel 包名 ：FLINK 版本号 ：1.9.0-bin-scala_2.12 运行环境 ：el7 el6是代表centos6系统，centos7则用el7表示 ps : parcel必须包置于/opt/cloudera/parcel-repo/目录下才可以被CDH发布程序时识别到。 (2)csd ：csd文件是一个jar包，它记录了服务在CDH上的管理规则里面包含三个文件目录
