I'm doing my baby steps in node.js, and i'm trying to understand sandbox mechanism. Currently i'm using node v4.0.0 and node-inspector v0.12.3. I've installed gf3/sandbox module and run it with this simple code: var s = new Sandbox(); s.run('1 + 1 + " apples"',function(output) { console.log(output.result); }); In order to debug easily, i've also c
我正在做node.js中的宝贝步骤,并且我正在尝试了解沙箱机制。 目前我正在使用节点v4.0.0和节点检查器v0.12.3。 我已经安装了gf3 / sandbox模块,并使用这个简单的代码运行它: var s = new Sandbox(); s.run('1 + 1 + " apples"',function(output) { console.log(output.result); }); 为了容易调试,我还评论了sandbox.js文件中的超时函数: // timer = setTimeout(function() { // self.chil
This question is about toolkits which draw graphs (those things composed of vertices and edges), not generic plots. The tool must be able to get a set of vertices and edges, calculate their layout, and display them either using the canvas tag, or SVG, that is be compatible with HTML5. Flash-based tools and java applets are out. to serve as unified benchmark, please measure and report how lo
这个问题是关于绘制图的工具包(那些由顶点和边组成的东西),而不是通用绘图。 该工具必须能够获得一组顶点和边,计算其布局,并使用与HTML5兼容的画布标记或SVG显示它们。 基于Flash的工具和Java小程序已经不存在了。 作为统一基准,请测量并报告工具包需要多长时间来布局和绘制每个节点具有100个顶点和5个边的Barabasi-Albert图。 这python lybrary演示如何生成它并将其导出为多种格式: http://networkx.lanl.gov/
