Mirror an image using Pure Javascript/JQuery

阅读更多关于 Mirror an image using Pure Javascript/JQuery

问题 Due to device restriction, I had to use only javascript or JQuery to "Mirror" an image. I had tried Reflection.js but that is not I want. What I want is to simply "mirror" the img tag's image. Anyone can help ? Thanks in advance. 回答1: Try this example mention in jsfiddle : CSS : div.reflection { -webkit-transform: scaleY(-1); -moz-transform: scaleY(-1); -o-transform: scaleY(-1); -ms-transform: scaleY(-1); transform: scaleY(-1); } img{ height: 150px; width: 150px; } HTML Code : <div> <img src=

Right way to mirror a PHP/MySQL setup

阅读更多关于 Right way to mirror a PHP/MySQL setup

问题 I just created my very first PHP/MySQL site and was looking into creating a mirror of the db for backup. This is of course, in case some hacker manages to go snooping and wrecks the main db. Is there a right or wrong way of doing this? Edit: Yes, I have a hosting plan in some other host that I'd like the mirror to be placed in. 回答1: There are mainly two ways for backing up your mysql databases: cold(static/offline) backup & hot(dynamic/online) backup. 1 Using a crontab script backup your db

阅读更多关于 how to sync a repo mirror to a new upstream repo

问题 I have a repo mirror server (myrepo) that was originally created to mirror and sync with a remote (repoA). That is, I used something like the following to create it. cd myrepo repo init -u git://repoA-server/manifest.git --mirror repo sync ...then I modified manifest file's fetch line to use myrepo server so users can clone from myrepo mirror So now repoA is gone and doesn't exist anymore. It has been replaced with a new repoB server at a different URL which has modified some of the branches

阅读更多关于 In Swift, can you find all types in a module that adhere to a specific protocol?

问题 In Swift 4, is it possible to find all types within the current module which adhere to a specific protocol? For instance, say I've defined this protocol and these classes: protocol Animal{} protocol Vehicle{} protocol Favorite{} class Dog : Animal{ } class Cat : Animal, Favorite{ } class Car : Vehicle{ } class Bicycle : Vehicle, Favorite{ } I want to find all types that implement Favorite . This can be easily done in C#, but I’m not sure if you can in Swift. Cat Bicycle If it helps, I'm using

Mirrored text in textview?

阅读更多关于 Mirrored text in textview?

问题 Im trying to do an application that simply outputs a bunch of text to the android screen, the problem is is that it has to be mirrored (Will be viewed as a "hud"). Surprisingly, in android 4.0, you can do this with a textview by simply going textview.setScaleX(-1)... prior to 4.0 I cant find much. textview.setTextScaleX(-1) doesnt work (actually it kinda works, but only one char comes up, though it is mirrored). The 4.0 approach also works on my phone (nexus s running cm9). I've stumbled

Mirror SVN Repository [Write-through proxying]

阅读更多关于 Mirror SVN Repository [Write-through proxying]

问题 I have a codebase located in Europe and access this codebase from Asia. Codebase is substantially huge, downloading the whole codebase (which is required sometimes) becomes a pain. I wanted to know whether anything like this. I want a solution that "I will have a svn server locally which will sync with the main svn and serve my team as the svn is locally hosted." Thanks in advance Munim 回答1: Try Multisite Repository Replication with VisualSVN Server. That's exactly what you were looking for

Safe master-master setup with git? (writable git mirror)

阅读更多关于 Safe master-master setup with git? (writable git mirror)

问题 Have set up a master git repo and a mirror of it. After some experiments I detected a typical conflict resolution (mis)managment: without a warning, git just dropped conflicting commits -- a pretty much insane default setting. After some perusing of SO, I tried git config receive.denyNonFastForwards 1 git config receive.denyDeletes 1 but that does not solve the lost commit issue. When there are two conflicting commits in the master and in the mirror repo, git remote update git push --mirror

How do I create a mirror for Eclipse Indigo SR2 (3.7.2)?

阅读更多关于 How do I create a mirror for Eclipse Indigo SR2 (3.7.2)?

问题 When I tried to update Eclipse to the latest SR2, I got a download rates around 10kb/s - which means I couldn't even get the content.jar . Which means I need to setup a mirror for the other 10 developers. What is the most simple (= less than one day of work) and reliable (= automatic, scripted) way to do this? Note: Answers which point to the p2 mirror Ant task won't be accepted unless they come with a complete build script which contains all the IUs and versions necessary to mirror only 3.7
