Linux core code is daunting. It is like a snowball. Reading a part of the core often involves several other related documents, and you will soon forget what you did. This section provides some tips. 　　 System startup and initialization In intelbased systems, linuxcan use loadlin.exe or LILO to load the core into the memory and pass the control to it. This part of the program is located in arch/i386/kerneld/head. S. This file completes some processor-

find out what this difference is.But there's a little bit of a difference besides laughter and playfulness. But I can't tell you exactly what the difference is.I examined Edward the most carefully. His skins were less pale and I decided-flushed from the snow fight maybe-the circles under he eyes much less noticeable.I was careful to check Edward. His skin is not too pale, and I think--it should probably be the case after a snowball fight--the change

I don't think everyone will believe that it depends on luck. Here, I have to admire uncle's good means and

corner of the view' s image and its superview's image. so, a frame origin{x:20, y:15}Will create a composited image where the view's image is drawn on top of its superview's image, shifted to the right 20 points and down 15 points. because the frame and bounds rectangle of a view are always the same size, the image is composited pixel for pixel to its superview's image. this ensures there is no stretching or shrinking of the rasterized image. Remember, we re talking about just one composite op

[Online activity] temporarily increases online activity through activities (which may be new tasks, planned activities, or customer service activities) to reduce or prevent the loss of players in a short period of time. [Natural user growth rate] an average online cost is lower than [user arpu value] * [average life cycle of each user ]. If you can continuously increase the number of users, new play

application does not know what the plug-in wants to do. It just gets _ idtextensibility2 (or similar interfaces) and calls the initialization function (such as onconnection ). The plug-in obtains the initialization opportunity. Note that during initialization, the applicationDom ModelIs passed in. In _ idtextensibility2, the root interface is defined as the idispatch type, that is, idispatch * application. But it can actually be more common, such as iunknown * application. With this applicatio

used to collect user feedback, publish it. Collect feedback and repeat this process to release the next version. The sooner the better. If you release the first user-oriented product three months ago, you have been dragging on for too long. If you release the update package only once three weeks, you have been dragging on for too long. If it cannot be several times a week, an update is released once a week. Major updates are released every three weeks. 9. The only thing that makes sense is the

Google groups (toplanguage). Because the readers of my blog have a common language, therefore, this group was very popular at the beginning, and high-quality technical discussions further attracted more cool people to participate. After the snowball rolled up, it was very difficult to stop, nearly a year and a half, I have benefited a lot from this group discussion [1]. For non-programmers, scientific squirrels are a good example. 2) writing is for b

then gradually refine it; (2) bottom-up. First, define the conceptual structures of each local application, and then integrate them to obtain a global conceptual structure; (3) Gradually expand. First, define the most important core concept structure, then expand outward, and gradually generate other conceptual structures in the form of Snowball until the overall conceptual structure; (4) hybrid policy.

step. The general process is as follows (taking the X86 platform as an example ):. /Larch/i386/boot/bootsect. S -->. /larch/i386/boot/setup. S -->. /larch/i386/kernel/head. S -->. /init/main. start_kernel () in C (). For parts such as memory management, you can read and analyze them separately. My experience is: it is best to read the startup code in sequence and then read the topics, such as process and memory management. Each function should be implemented step by step. In fact, this is a rep

still fruitless after an hour ...... Go to rest! Drink a cup of water, browse your favorite blog, or run ...... Any activity that can keep you away from that code. Rest gives your brain the opportunity to find code errors again, and sometimes you may be inspired. Sometimes it is a waste of time to drill over and over again. 3.Incremental Mode Test (Incremental testing) First, start the test from a single module, and then add a module after the test to the system for testing.

In this way, the internal quality characteristics of the entire software system can be gradually and gradually improved, and the maintenance workload of the system can be gradually and gradually reduced; otherwise, with the increasing amount of software code, increasingly complex system functions, and frequent chan

receive errors 14412863 packets sent RcvbufErrors: 3596307 SndbufErrors: 0 From the above output, we can see that one row of output contains "packet receive errors". If netstat-su is executed at intervals, the number at the beginning of the row keeps increasing, indicating udp packet loss. The following describes the common causes of udp packet loss caused by the application being too late to process: 1. the Linux kernel socket buffer is too small# Cat/proc/sys/net/core/rmem_default # Cat/proc/

the parent view, and the origin of the frame indicates the offset of the upper-left corner of the view's rasterized picture relative to the upper-left corner of the parent view's rasterized picture. Therefore, a frame of origin {x:20, y:15} draws a picture to the left of its parent view 20 points, and the top margin is 15 points from the parent view. Because the frame and bounds rectangles of the view are always the same size, the rasterized picture is pixel-aligned when combined. This ensures

The spin-off plan aims to break the bottleneck of the development of the engine, which restricts China's large passenger aircraft and large-scale transport aircraft, and then the Chinese aero engine and machine will be developed separately to break the old aviation industry model of "one factory one model".For the "Two-machine special" (that is, the national aviation engine and gas turbine "two machines" technology major Special) time no
