[Size=large]openfire enables friend addition and group management.Mainly based on two table implementations: Ofroster,ofrostergroups.Ofroster: Used to record a friend relationship (a pair of friends with two records to achieve)Ofrostergroups: Used to record buddy groupsSpecial Note: OpenFire the user's primary key is the natural primary key, namely username. The self-increment ID is not used.Let's take a look at the official (http://www.igniterealtime

During the time when the kernel was started to execute the mem_init () function, the buddy system was not initialized. In this phase, the data space that the kernel can directly access includes data in the data segment, BSS segment, and sdata segment of the kernel. However, when the kernel is initialized, it is inevitable that the dynamic memory will be used. In this case, if the buddy system does not exist

Google Reader is a must-have for us (pseudo) geek to get information, but it seems to me rather unpleasant. the ubiquitous search bar above always seems a waste

I thought it was the last side and it would be faster. I didn't expect that there were other people in the interview this time, and there were many people in the last side, A buddy said that he had been waiting for a month. He didn't want to come. The personnel called him many times. Today, he

When the kernel itself needs memory, it always applies to the slab layer (?). A new data structure needs to be created. When a buffer is required, slab allocates a continuous memory for it. The kernel does not need to map this memory. As long as this continuous physical memory is within MB, it is in a state that is "ready to be used by the kernel. After being split from slab, it is "officially used by the kernel ". In the e
Memory-related operational functions in the Linux kernel1, Kmalloc ()/kfree ()static __always_inline void *kmalloc (size_t size, gfp_t flags)The kernel space requests a memory area of the specified size and returns the virtual address of the kernel space. In the implementation of the function, if the requested memory space is large, a number of memory pages will be requested from the buddy system, and if the requested memory space is smaller, the memo
experience is poor.
For the above reasons, many projects now make some of the functionality web-style, and some of the functionality is written with other controls. This requires a Web page to interact with other controls. How to interact is to take advantage of custom JavaScript.

Now there is a feature that shows the current user's buddy list, buddy list page is the Web way, c
order of the two controls contiguous, and the tab order of the edit box is in front. In the dialog box, the TAB key moves the input focus from one control to another in a sequential order, called the tab order. Because the default Control tab order is the same as the control you add, we add the above control by adding an "edit box" before adding a "rotate control". In addition, you need to set its alignment (attached) property to right-aligned in the Properties window of the rotation control to

Object A;Private Object second;}As you can see, this is a generic class, all of which are replaced by the object type, which is called the native class. Whenever you instantiate the paradigm with a specific class, the compiler satisfies the requirements by enforcing the constraints and adding the enhanced conversion code where needed, but does not generate more specific classes (this is completely different from C + +), based on the native class. Let's illustrate this point: pairIn the above na

The memory management of Bfin-uclinux kernel mainly involves three kinds of algorithms, Bootmem,buddy and slab. The Bootmem, which works at the beginning of the kernel, organizes the available memory of the system as a page. The buddy algorithm then takes over the pages and divides them into blocks of different sizes, and when this completes, the Bootmem exits the stage and no longer appears. The slab algor
