a file or directory, you can add the-i parameter to the LS command. Move (aka Rename file): $ mv/home/christine/pictures/fzll/home/christine/fall Remove: When using the RM command, develop a good habit of always adding the-I parameter. 6. Create and delete directories: With the mkdir command, you can: $ mkdir new_dir The basic command to delete a directory is rmdir. By default, the RmDir command removes only

the number "greater than equals" symbol, you should use ">=" instead of "=".In PHP "::" This is called the scope resolution operator, aka domain operatorThe "::" symbol can be thought of as "." In the C language. Similar, and it is more like C + + (Perl):: Class-scoped operators.PHP calls the internal static members of a class, or calls between classes using:Here is an example:class A{static $count = 0;static function haha (){//}function Diaoyoug (){

definition: In an event-driven environment, such as a browser that continues to seek user attention, the Observer pattern (aka Publisher-subscriber "Publisher-subscriber" mode) is a relationship between the manager and his or her task (specifically, the relationship between its object and its behavior and state).) is a powerful tool. In JavaScript, the essence of this pattern is that you can observe the state of an object in the program and be notifie

Recently full conversion development to Mac OS, with Macvim as IDE. Record some vim basic operations to your own memo.This is said in Common-mode (C-mode, in the Vim aka Normal-mode, is just into vim, can not enter the text of the state) under the movement, the original VI can only move the cursor in the C-mode, In Insert-mode only the input of the text, not the movement of the cursor. Of course, Vim and Elvis's arrow keys are movable freely in either

The second parameter of watch accepts two parameters: New Value and old value. We can use them to skip the first execution. Generally, you do not need to sk

There are three ways to persist iOS data: List of properties (custom property list, Nsuserdefaults) Archive (Nskeyedarchiver) Database (SQLite, Core Data, third-party class libraries, etc.) The following is a main introduction to an archive nskeyedarchiver. Archive (aka serialization), convert objects to bytecode, save them to disk as files, and restore them by unpacking (deserializing) the program as it runs or when it i

Cordova 3.x Foundation (1)--Environment construction (windows/android)The Mobile app is divided into three main categories: Native App,hybrid app,web app. The hybrid app is between the native app and the Web App, which takes into account the native app's good user experience and powerful features, as well as the advantages of rapid web app development across platforms. The disadvantage is that relying on the performance of the Webview,webview of each platform directly determines the performance

automatically back up data in a timely manner through the network. The following describes a simple method. You only need to set up Ubuntu 10 to turn your computer into a Time Machine backup server. (PS: in theory, all Linux systems can be implemented. Because I use Ubuntu 10.10, I will only introduce how to set this system) 1. Install Netatalk Netatalk is a free and open-source AppleTalk communication protocol. Linux or BSD can act as the Mac file server (AppleShare file server,

consider hashmap capacity), when the number of elements increased to 16*0.75=12, the array length will automatically increase by one times, the element position will be recalculated. In the case of a huge amount of data, we should consider initializing enough array lengths when initializing HashMap, especially if performance first, we can also appropriately reduce the ratio of element capacity to array length. HashMap Part Source: /*** The default initial capacity-must be a power of. */ S

I had some trouble installing Webmin 1.510 on Ubuntu 10.04 LTS Server (aka Lucid). The problem is this Webmin uses a deprecated Perl module (a wrapper around Digest::md5 for users of an ancient MD5 library ) and both Debian and Ubuntu refuse to put it back into their respective repositories. Entirely within their rights, of course, but not so good for us weekend admins who want a painless install process.Okay, so let's get to work. I ' m installing We

Links: blog.jobbole.com/77280/Github.com/kenfox/gc-vizMost developers think of the automatic garbage collector as a matter of course. In fact, this is just a practical feature of the language runtime, designed to simplify our development efforts.But if you try to understand the internal workings of the garbage collector, you'll find it hard to figure out. Unless you're familiar with its workflow and error handling, you'll be overwhelmed by the thousands of implementation details inside.I compile

Architecture, aka Software architecture, is an abstract description of the overall architecture and components of the software that guides the design of large software systems in all aspects.In terms of what a pattern is, the word from architecture is defined as: "Each pattern describes a problem that recurs around us and the core of the solution to that problem. This way, you can use the program again and again without having to do repetitive work. "

hybridization.In 1996, Microsoft finally realized the importance of the Internet and increased its support for home browser ie, including JScript, so there were two different JavaScript versions on the market at a time. This historical source heralds the untold pain that later programmers have endured to deal with compatibility issues.Finally, in 1997, the European Association of Computer Manufacturers (ECMA) developed the standard ECMA-262 (aka ECMA
