development process. These bottlenecks can take a lot of the programmer's time, and you won't be able to foresee them before you meet them. They stall the whole project, causing the schedule to be delayed for weeks or even months. These are inexperienced people who don't understand when evaluating complexity. They don't understand how it's going to work in other ways, and why it's not in software development. So, the next time you hear someone say, "I think you can develop it in a few days," n

add up, and this gets the approximate time required to complete the project. However, in fact, each project encountered two or three bottlenecks in the development process. These bottlenecks can take a lot of the programmer's time, and you won't be able to foresee them before you meet them. They stall the whole project, causing the schedule to be delayed for weeks or even months. These are inexperienced people who do not understand the complexity of the assessment. They don't understand how it'

Two major breakthroughs in processor history: Pipelining allows the processor to execute multiple instructions at the same time, and parallel technology allows the processor to execute multiple threads at the same time. Recently looking at Wcet (worst case execution time, worst execution times) In the software system, WCET includes three aspects: one is the multi-core processor when multitasking to the operation of shared variables, and the second i

Technology is the realization of design ideas, a design idea can have a variety of ways to achieve. For example: How do we understand "lazy loading", there is a person ready to go to your house for a few days next month, you need to vacate the room this month. This month, when he doesn't exist, wait till he comes. The design study is how to deal with the relationship between object and object (using) design ideas originate from the problems enc

First, encryption technology 1. General Data encryption model Note that there is a key on the A and B side. 2. Two Class cipher system A) symmetric key cryptosystem and public key cryptosystem are divided according to whether the encryption key and decryption key are the same. b) in a symmetric key cryptosystem, the encryption key at the end of a and the decryption key at the B end are the same. This kind of commonly used encryption algorithm has DE

block to improve the subjective quality of the human eye. B, h.265 Code codec Optimized encoder Parameters--h.265 codec This is the h.265 coding framework, which is the same as the mixed coding framework of H. For example, including inter-frame, intra-frame prediction, Entropy coding, deblocking in order to remove the "block effect", adding a new SAO filter to eliminate the ringing effect. Comparison of parameters between C, H and h.265 As for the H. h.265 framework, although their proce

. 1. I am sitting on a mountain In fact, I did not sit on any mountain, but on a chair in a cold office without an automatic thermostat. What I really want to say is that this article is based on a lot of background knowledge about Java 3D and JMF. In this article, I will explain the JMF technology I used to extract animation frames from a video, instead of discussing technologies such as streaming media, capturing, or code conversion. 　　 2.

the DNS server is true.Let's look at the problem from another perspective. We know that it is possible to directly paralyze the DNS server. Recall that the attacker wanted the DNS server to ask for resolution of www.attacker.net. Thanks to the malicious zone transfer record from ns.attacker.net, the attacker could paralyze the DNS server's high-speed cache. It is worth mentioning that the limitation of such attacks is that attackers must run their own DNS servers with malicious records.In this

[Keyword] Mobile phone roaming, hearing, roaming fee With the approaching of the mobile phone roaming fee hearing, "Roaming" outside the public's field of view "mobile phone roaming fee" has become the focus of public opinion. What is the technical process of mobile phone roaming? What is the cost? The reporter recently interviewed relevant experts and asked them to elaborate on the mystery of "mobile phone roaming. Mobile Roaming is a "low tec
