not need to configure IP address, mask, Gateway, The startup protocol is set to none, but make sure that the NIC is powered on.The storage network, as its name implies, transmits data that is stored in a specific format and does not have a default gateway, as long as it ensures interoperability between compute nodes and storage nodes.650) this.width=650; "title=" 2014-12-02_091822 "style=" border-top:0px;border-right:0px;border-bottom:0px; border-left:0px; "border=" 0 "alt=" 2014-12-02_091822 "
third layer can specify 256 numbers, so the total size is as above;
Total: Direct, indirect, double indirect, three indirect plus total, get + + + 256*256 + 256*256*256 (K) = 16GB
At this point we know that when the file system to the block format 1K size, can accommodate the largest file is 16GB, compare the file system limit table results can be found to be consistent! However, this method can n

File workDir = Context.getDir(dirName, Context.MODE_PRIVATE);Log.e(TAG,"workdir "+ workDir.getAbsolutePath();
Summarize the file related operations, you can draw the following three features:1. File operation only need to provide a file name to the function, so the program itself only needs to maintain the file name;2. No need to create file object and input, output stream, provide file name can return file obj
, output stream, provide file name can return file object or input output stream3. The file object is returned for the path operation.2. External storage:The most confusing is the external storage, if the PC is also to distinguish between external storage and internal storage, then the drive is internal storage, U disk or mobile hard disk is external storage, so we can easily take this understanding to look at the Android phone, think that the intrinsic storage of the fuselage is internal storag

consistency when a system failure event occurs.
3. NTFS supports compression of partitions, folders, and files. Any windows-based application that reads and writes compressed files on an NTFS partition does not need to be uncompressed by other programs, and the files are automatically decompressed when the file is read, and the files are automatically compressed when the file is closed or saved.
4. NTFS uses smaller clusters to manage disk space more efficiently. In the case of the FAT32 file
consistent and can be rebuilt (_reproducible_) build environment. Because this has some requirements for CPU and disk space, here are the minimum configuration requirements for some hardware:Raspberry Pi 3 (pi 2 is OK, but the build takes longer)16GB size SD card (8GB is not enough!) )Enable swap space (1GB size of memory is not enough)Docker Engine 1.11
Installing the Build Environment
As you'll soon see, building a build environment is very simpl
Failure phenomenon:
Some of the ThinkPad preinstalled mSATA SSD shipments do not have the Expresscache software installed, resulting in the inability to use the mSATA SSD as a cache.

1, open the "Start" menu, click the "Run" button
2, in the pop-up window input "CMD", and then determine or press ENTER.
3, in the command window input "wmicmemphysical get Maxcapacity" and then hit the ENTER key.
4, then the computer will give a string in kilobytes as the number of units. We're going to convert this number to our usual GB unit.
The conversion method is: "The number that comes out/(divided by) 1024/(divided by) 1024"

bytes, leaving the operating system (OS) to handle it! This is the design decision that allows MongoDB to run in RAM without any modification.
Implementation methods
All this is done by using a special type of file system called TMPFS. In Linux it looks like a regular file system (FS), but it's completely in RAM (unless it's larger than RAM, and it can be swap at this point, which is useful!). )。 My server has 32GB of RAM, let's create a 16GB TMPFS
we can double compress the hibernation file to minimize the amount of disk space that the hibernation file takes up without losing the hibernate feature. Of course, we also need to pay attention to this, reasonable resolution due to the size of the sleep compressed file is not suitable for the blue screen to appear problems.

or click "Restore".
Restore the computer without affecting your files
Step 4: Under "Restore your computer without affecting your files," click or click "Start".
Step 5: Click or click Next to make sure the Surface is plugged in, and then tap or click Restore. Surface will reboot and the Surface logo will be displayed (this may take several minutes) when the recovery process is complete.
Method Two: Restore the system from USB
Before we introduce the method, let's introduce how
can format the startup disk for a new installation.
6. Not high requirements for hardware
Microsoft's official minimum hardware requirements for Windows 10 technology previews are 1GHz and above processors, 1GB (32-bit) or 2GB (64-bit) RAM, and at least 16GB hard disk space, so older PCs can also be easily upgraded. In addition, the system cannot run on RT and Windows N devices.
7. Only laptop and PC support
