In October 2004, IBM unveiled the visual modeling tools that support the latest UML2.0, rational Software Architect (see annotation ①) and IBM Rational Software Modeler (see note ②). While they support better improvements in modeling capabilities and support for newer standards, RSA's wonderful features are focused on support for Java applications, while IBM Rational Software Modeler is a major focus on the system's model design, if you want to analyze the structure of C + + Code for the system,

　　"Introduction to Software Engineering Practice" This book is published by Tsinghua University Press in 2005, the author of Fairmont and. The choice of this book as the job selection, is because a senior hand has the book, but also recommended to me this book is worth a look. But the book is relatively thick, and the content is not simple, so I can only be a little bit.The book in front of some of the soft

methods of calculation and modeling to improve the computational approach itself. Products Software (such as Office packages and compilers). Algorithms (such as the hill Sort method) and abstract questions (such as philosophers eating questions). Schedule and schedule Software projects have specific schedules and schedules Research projects generally do not have a set schedule and schedule Focus Point Software

the kernel's EBPF syntax and registers are complex, similar to real assembly code.So why does the kernel have to go through the trouble of implementing such an engine? Because it's lightweight, secure, and portable. Because it is intermediate code, portability does not have to be said, but using kernel modules to invoke the kernel's function interface is generally portable, so this is not a very important reason. EBPF code in the implementation of the process is strictly restricted to prohibit

efficiency, but requires less resource overhead (memory and CPU), so most of the slob is used in embedded systems, but the current embedded system computing power is generally strong, So slob basically out of the historical stage.Memory Policies: PolicyBecause of the advent of NUMA, it is necessary to allow the user program to control where its memory is applied. Mpol_default, mpol_preferred, Mpol_interleave, and mpol_bind, memory policies inherit from the parent process.The memory used can als

, there are other similar mechanisms, such as EVMS, Dmraid. But LVM is widely used.Working styleThis mechanism cannot be done only in user space and requires code assistance in kernel space, which is Device-mapper (Dm_mod module). The Dm_mod module completes the conversion of the IO request, which is essentially a mapping as in memory management. The code is located in DRIVER/MD. This part of the code is a vivid embodiment of the separation of policy and mechanism, the policy is specified by the

corresponding interrupt processing function, processing multi-CPU access and interrupt re-entry problems, and then invoke the real interrupt processing function, that is, the upper layer of interrupts. However, the kernel makes a difference here, if the kernel determines if the interrupt has been nested (at the same time more interrupts), the interrupt handler function is run as a kernel thread, otherwise it will run directly. So, we can often see in the output of the PS command:These soft inte

elements. The maximum range that can be computed is 10,0000, and it takes about half a minute to calculate the 10,0000. In addition to the computed range, it is almost equal to the dead loop and the operation time is too long.Solution: The solution to the direct response is to change int to longint or to a wider range of other types.

key point in cubic is that its window growth function depends only on the time interval value of the successive two congestion events, thus the window growth is completely independent of the network latency RTT, and the hstcp described earlier has a serious RTT inequity, The independent nature of the rtt of the cubic allows cubic to maintain a good RTT fairness between multiple TCP connections that share a bottleneck link.Stcp,scalable TCP.The STCP algorithm was proposed by Tom Kelly in 2003 to
