Introduction to Private Browsing mode Browser is an essential tool to surf the Internet, when we surf the internet every day, the browser will faithfully record every step of the user's footprint, so some people began to worry about whether personal privacy will be leaked, especially when the need to use others or public computers. Of course, on privacy issues, browser developers do not ignore, so our daily use of browsers provide a clear view of the

array, the value of P3 is the address of the one-dimensional array.Above, equivalent to a two-dimensional array.Results:According to the above explanation, have you reached the answer?3. Function-relatedSometimes, we also encounter the following situations: int *p (): function that returns a pointer Int (*p) (): Pointer to function ①. int *p () pointer functionIn fact, it is a function, except that the return type is a pointer, and it is no different from the norma

Many users after the installation of WinXP system, is always found in the process of a program ekrn.exe, often occupancy rate 100%,ekrn.exe is something? In fact, it is Norton Anti-Virus software in an anti-virus related program, many WinXP genuine CD-ROM are installed with Norton Antivirus software, That is why this problem arises. So how do we solve the problem? We can start with the following. When Ekrn.exe memory occupies 100%, resolve steps: 1, make sure you have installed the Microsoft o

Server CPU, memory normal, some sites can not open, application pool recycling is normal, how to solve? Questions: Server \iis and ASP issues I would like to ask next you ' site recently a few times a day to play not open very slowly ' only show tile title other No, the site is ASP, foreground-generated HTML, today saw the W3WP.exe occupancy up to 280M, Generally only about 170M of IIS management in the address pool to reclaim the normal "what is the reason?" Add: Server CPU usage is very smal

Once a friend asked me a question, a 512*512 150KB png format picture and a 512*512 100KB compression ratio is 8 jpg format picture, loaded into memory, that is, loaded into a bitmap, which occupies a large memory? This question seems to be a little difficult to answer, the test will know. Well, I've got three pictures on request, 1.512*512px, 114KB, PNG 2.512*512px, 138KB, JPG, compression ratio 12 3.512*512px, 57KB, JPG, compression ratio 8 The next step is to write a demo, a bitmap load

Java memory can be divided into: heap and meta space. To View the heap: Jmap-heap PID View Metaspace: Use JSTAT-GC pid mc Mu. to view other uses in the process: The RS occupancy in top is minus the footprint in the jmap-heap. /proc/$PID/maps Smaps is a more detailed information Pamp Pid:anon means memory allocation. $cat/proc/1756/maps | grep deleted to search for "Free State of the mmapfile, once the Free State, here will show that the file has been

, so a page can hold more than 8 inode structures, so the inode structure is a small object. Objects less than 512 bytes are called small objects in the Linux kernel. In fact, the buffer is the main memory of a region, dividing the area into multiple blocks, each piece is a slab, each slab by one or more pages, each slab storage is the object. 2, view slab cache information through the Slabtop command Through slabtop we see the Linux system has a large number of dentry cache memory

, the buffer/cached will be quickly recycled. Measurement of memory footprint Measuring how much memory a process consumes, Linux provides us with a convenient way, the/proc directory provides us with all the information, in fact, top and other tools to get the appropriate information. The code is as follows Copy Code Memory usage information for/proc/meminfo machinesThe/proc/pid/maps PID is the process number that displ

look at the process PS aux, this look found the problem, there is a script in the process of a lot of production, Execute the following command immediately to kill: The code is as follows Copy Code Kill-9 $ (PS aux | grep process name |GREP-V grep| awk ' {print $} ') Now look at memory usage, memory is finally normal, OK, and then observe a few minutes, no problem out of the server, continue to check the problem of the script. PS: The thing to emphasize h

How do I see the disk footprint of each table space? Software Environment: 1. Windows nt4.0+oracle 8.0.4 2, the Oracle installation path is: C:\ORANT SQL statement: /* Chinese Environment * * Col table space name format A20; Select b.file_id file ID number, B.tablespace_name table space Name, B.bytes byte Count, (B.bytes-sum (NVL (a.bytes,0))) has been used, Sum (NVL (a.bytes,0)) remaining space, Sum (NVL (a.bytes,0))/(b.bytes) *100 percent rema

As we all know, Windows 8 was launched with several versions, including a Windows RT system for the ARM platform. The ARM platform has some limitations compared to the PC platform, and here's a look at how much memory is occupied. I'm using ASUS TF600T's RT tablet, which is not surface RT, but both use similar hardware configurations and the system is also Windows RT, so the memory footprint can also be referenced. First, let's take a look at the sys

iisapp.vbs, if you and I also prohibit the VBS default affiliate program, then you need to manually go to the directory, select Open mode, and then select " Microsoft (R) Windows Based Script Host "to execute, you can get the corresponding relationship between the PID and the application pool." ）4, to the IIS to view the application pool corresponding to the site, OK, make the above memory or CPU restrictions, or check the program has a dead loop and so on. 5, find out the most CPU-consuming SQ

to do this is because the above operation only in the operating system to the unused space to zero, the virtual machine does not know, so it is necessary to pass this step, so that the virtual machine will not use the space also zeroed.9. Migrate the virtual machine again, change the virtual disk format from "thick provisioning" to "thin provisioning", you can see that the space used to reduce to 10GB, that is, the actual occupied space is actually reduced.The above experiment basically verifie

window toolbar (Update Heap),(4) Click the Cause GC button on the right window to get the heap information of the current program.Similarly, as the program runs, multiple clicks to get the heap size, if only increase, it also indicates that your program has a memory leak.3. ADB command to view memory informationIn fact, the most comprehensive and simplest way is to use the ADB command to view the memory footprint and memory leaks of the program, open

A lot of people have been confused, "size" and "footprint (size on disk)" In a file or folder property usually do not match each other. The value of size represents the number of bytes in the actual size of the file, while the space-occupying value table file occupies the size of the hard disk space.This difference comes from the way the file system stores files on the drive. To reduce the number of addresses used, the file system treats a certain num
