No matter what programming language you use, you will face the problem of how to handle the error log. Many programmers leave the error log, until the failure of the regret, if asked small, I will recommend Sentry!650) this.width=650; "Src=" http://mmbiz.qpic.cn/mmbiz_jpg/ Vgsq2bll9klzp6bkdkd4z6zskbk6kvurhczibyq8iczh9ib5kf8mmbpi4ymckaovsfbmnrjo9unswitlvaxmkibj2q/640?wx_fmt=jpeg tp=webpwxfrom=5wx_lazy=1 "style=" Margin:0px;padding:0px;height:auto;width

This article, which stands in the GUI designer's perspective, outlines the process of the app starting from the project to the slice output, which is equivalent to an introduction to Workflow. Here is not a specification, but a working method, coupled with the technical update is very fast, everyone in the specific work, must be flexible use.Here we only talk about the design of the iOS system, as for Android, because of the size of too many things involved in a mess. 1Part 1 Project Establishme

The video features in the recent project need to be fully compatible with the browser, so the video functions previously implemented with HTML5 need to be transformed. Over the internet, try to try, in all the video player, the number of its most practical. First, let's look at its advantages:1. It is open source free and you can easily get its latest code on GitHub.2. It's very easy to use it, just take a few seconds to rack up a video playback page.3. It is almost compatible with all browsers,

ICML 2016 's article [Noisy Activation Functions] gives the definition of an activation function: The activation function is a map h:r→r and is almost everywhere.The main function of the activation function in neural network is to provide the nonlinear modeling ability of the network, if not specifically, the activation function is generally nonlinear function. Assuming that a sample neural network contains only linear convolution and full-join operations, then the network can only express linea
