1) What is a raw table? What is it?
Iptables has five links: prerouting, input, forward, output, postrouting, and four tables: filter, Nat, mangle, raw.
The priority of the four tables ranges from high to low: raw --> mangle --> Nat --> Filter
For example, if there is a mangle table or NAT table on the prrouting chain, mangle will process the table first and then
Raw is a digital camera special format, can be called "electronic film", is the original image encoding data. Raw format photos record the digital camera sensor raw information and some of the data generated by the camera, including the image of sharpness, saturation, contrast, color and white balance of the various information.
The raw type is a data type that is used in Oracle to hold a bit string, similar to char, declared with a raw (L) method, up to 32767 bytes long. The system provides a SYS.UTL_RAW toolkit for raw type operations, and the commonly used functions are as follows:

Taking photos in RAW format is a big advantage for digital SLR cameras. Raw format contains a large number of image information, compared to the JPEG format adjustment is more powerful, while the resulting loss of the screen is correspondingly lower, we will introduce Photoshop camera Raw p
Currently, digital cameras are stored in the same format as JPEG and Tiff, as well as raw. What kind of format is raw? Under what circumstances should I use this raw format? What are the advantages and disadvantages?
In fact, raw is not an image format and cannot be edited directly.

Raw file as a kind of image storage data format, only record the original information of the digital camera sensor, provide more flexibility for the post-processing of the digital image, which is favored by many photographers. In general, we can use the official software to buy the camera to open and process raw format files, but if you usually use several different brands of cameras, and each camera manufa
Today we will mainly introduce you to the interpretation of common Oracle Raw types. We all know RAW, which is very similar to CHAR. We declare it in Oracle RAW (L ), L is the length, in the unit of correlation bytes. It is used as the maximum 2000 bytes of the actual database column and as the maximum 32767 bytes of the variable.

There are two kinds of raw material procurement situations: one is to first receive the goods and pay according to the actual amount of goods received; the other is to pay first, and the other party then delivers the goods. For domestic suppliers, the former is usually used for processing, but some imported raw materials, the other party will require fi
The most important thing to do with SAP is materials and teaching materials. I had a problem with my mobile hard drive two days ago, so I had a poor idea about more than 100 GB of data.
The problem is: the format of one of the three shards is raw, and the size of the byte is-0kb.
I used finaldata. The speed is too slow, the directory is incomplete, and I gave up. I can use diskgeniust to find data. Unfortunately, most of the documents are damaged;

The following articles mainly explain the Oracle Raw type in detail. We first talk about the concept of RAW, which is similar to CHAR in that aspect, the declared method is RAW (L). It takes L as the length, and the relevant bytes as the unit. It serves as the maximum 2000 bytes of the database column and the maximum 32767 bytes of the variable.

Use Raw Socket programming in C # To monitor network packets
When talking about socket programming, you may think of QQ and IE. That's right. Many other network tools, such as P2P and NetMeeting, are implemented at the application layer using socket. Socket is a network programming interface that is implemented on the network application layer. Windows Socket includes a set of system components that
In versions earlier than RedHat5, the system configures the raw control file through/etc/sysconfig/rawdevices and manages the startup and shutdown of raw devices through/etc/init. d/rawdevices. After RedHat5, the original raw device interface has been canceled, and RedHat5 is configured through udev rules. To configure, edit the/etc/udev/rules. d/60-raw.rules fil
Recently, when studying the V$latch view, I found a data type that I had never seen before. The data type of the Addr property in V$latch is Raw (4|8) and the data type of the addr attribute in v$process is also raw (4|8). So we looked at Oracle's SQL Language reference documentation, as described in the following document:The raw and LONG
