Many people like to intrude into Win2000, and there are also interface-based remote control such as 3389, so many vulnerabilities can be exploited, and articles about intruding Win2000 are everywhere, convenient. However, do you know what footprint you have left in the system? I recently made an intrusion analysis and found a lot of things. Of course, it is estimated that the intrusion time will be listed in the search file. Here, we will not analyze

Before Android 2.3.3 (API level 10), bitmap pixel data and bitmap objects are stored separately, pixel data is stored in native memory, objects are stored in Dalvik heap, native The pixel data in memory is not released in a predictable manner and may cause the application to temporarily exceed its memory limit and crashes, so before Android2.3.3 (API 10) You have to call the Recycle () method

Recently to change the office, found that the Windows7 C disk space is really more use less, according to my experience, although the file of the C disk is very large, but the majority of the occupied should be a few, so I wrote a script, ran a C disk, the folder larger than 100M to find out, produced a xmind diagram, Sure enough, as I think, delete a few big, C disk a lot of empty, also for the C disk space is not enough friends can see my picture, maybe you and I have the same folder OH:)650)

The NCDU command is an enhancement to the functionality of traditional du commands, where you can calculate file and directory sizes and sort by size or file name without having to enter a large number of commands like Du. It is based on the ncurses library and therefore supports many rich interactive commandsNCDU's official website is as follows: HTTP://DEV.YORHEL.NL/NCDUInstalling NCDUCurrently the latest version is 1.6,:http://soft.vpser.net/manage/ncdu/ncdu-1.6.tar.gzAfter download, execute:
