System File Checker (sfc.exe) is a utility used by Windows to verify system file integrity and repair system files.In Windows XP, it is more powerful: Windows XP's "System File Checker" can scan all protected system files to verify its version, you can also set the File Cache size, clear the File Cache, and refill the "% SystemRoot % \ System32 \ Dllcache" folder.Enable "System File

The system provides the following validators:Required (required. The field value cannot be null)Requiredstring)Stringlength (String Length validator, which requires that the field value be within the specified range; otherwise, the verification fails. The minLength parameter specifies the minimum length and the maxLength parameter specifies the maximum length, the trim parameter specifies whether to remove spaces before and after the string before verifying the field)Regex (Regular expression va
Let nodeJS support ES6 lexical ---- install and use babel, nodejses6
To use Babel, we need the node. js environment and npm. nodeJS is installed mainly, and npm is installed by default. Now it is easy to install node. js. Just download and install it directly;
Install es-checker
Before using Babel, we need to first check the current node's support for es6. We use es-checker first and execute the following c

Telecom operators need to shift the focus of innovation from technology (such as HTML5, NFC, IMS, VoLTE, M2M, or RCS-e) to the ecosystem, so they need to better understand how the ecosystem works, how to absorb and enlarge innovation. The ecosystem perspective not only helps operators identify promising innovation plans, but also helps avoid investment in the absence of successful ecosystem factors.
When evaluating innovation investment, operators n
4G + technology can enjoy a higher rate than normal users ." Yan shuihua, an engineer at Shenzhen mobile network department, said, "for example, watching a video may take 5 Mbit/s. When many people watch the video, using a terminal that supports 4G + may have a higher probability of obtaining a 5G rate."
Beijing Mobile said that the 4G + construction will be the focus of work in the second half of the year, and about 9000 carriers will be completed by the end of the year. At the same time,
