Mingle: for agile, use mingle

mingle to do some complicated bookkeeping in the future? Like scrumworks?Later I heard that mingle was used for management personnel and BA, and I was gradually relieved. Is it true that cards, walls, and plasticine are enough to keep you up for regular activities? ---------------------------She is still like a lightning, a ray.So beautiful, beautiful instructors can endure, can wait, beautiful with a little childish, pure as if even this bea

9 misunderstandings about Java Performance

stop-the-world collector to collect data from earlier years, that is, the parallel old collector. Concurrent-mark-sweep (CMS) is an alternative. In most garbage collection cycles, it allows the application thread to continue running, but this is costly and there are some considerations. It is inevitable that the application thread and the garbage collection thread can run together. The application thread modifies the object graph, which may affect the object storage activity. This situation mus

Decrypts the descriptor in Python

): X = Descriptor ('y ') F = Foo () F. x = 5 Print f. x F. y = 4 # oh no! Print f. x _ Set __ _ Get _ 5 _ Get _ 4 I don't like this method, because such code is fragile and has many nuances. However, this method is indeed common and can be used in owner classes that do not support hashing. David Beazley used this method in his book. Use a tag-specific descriptor in the meta-class Because the Tag Name of the descriptor is the same as the variable name assigned to it, someone uses the Meta clas

decisions. The above is the official definition of the data warehouse."Operational database" is like a database of the bookkeeping system in a bank. Every business operation (for example, you have saved 5 yuan) will be recorded in this database immediately, all accumulated data is fragmented. This dirty and tiring database is called "operational database" and is oriented to business operations."Data Warehouse" is used for decision support and is orie

Python in co-process

Talk about Python processes and threads before you elicit the concept of co-formation.Process:The process is executing a program instance. During the execution of the program, the kernel will tell the program code to load virtual memory, allocate space for program variables, and establish bookkeeping data structure to record process-related information.such as process ID, user ID, and so on. When the process is created, the kernel allocates a certain

Manage and restore data files Data files are copies of files or non-active data is copied from online storage to offline storage. Keep regular or regular backups of important data with bookkeeping requirements, and transfer inactive data from expensive online storage to low-c

case, the estimated data should indicate that the expected implementation environment has the ability to provide resources. In more complex cases, applications may be required to manage resources more actively. In this case, the "Resource Manager" should be carefully designed in the same way as other parts of the system.8. scalability ? Scalability refers to the ability of the system to grow to meet future needs. The architecture should describe how the system handles the growth of user quantit

options, including: The allocation speed. Recovery speed. Behaviors in a threaded environment. Memory usage. Local cache. Bookkeeping memory overhead. Behaviors in the virtual memory environment. Small or large objects. Real-time assurance. Each implementation has its own set of advantages and disadvantages. In our simple allocation program, the allocation is very slow, and the collection is very fast. In addition, because it is poor in using the v

RaiI and garbage collection (below)

explicit destructor scheme is used, the methods for releasing resources are consistent (The Destructor object), and the exceptions that identify "invalid resource" are also consistent ("the object has been destructed "), this greatly reduces the programmer's bookkeeping burden. Q: (CONTINUE) but do you have another check? For each pointer access, you must check whether the object has been destructed and the efficiency is too low.A: This statement is

The new lock class improves synchronization-but synchronized jdk5 cannot be discarded now

than other threads that request locks first. Why don't we make all the locks fair? After all, fairness is a good thing, but it is not good to be unfair, isn't it? (When children want to make a decision, they always yell "this is not fair ". We think fairness is very important, and the children know it .) In reality, fairness ensures that the lock is very robust and has a high performance cost. To ensure the bookkeeping and synchronization required fo

Preliminary understanding of yarn architecture and principles

Submit a job The client calls the job. waitforcompletion method and submits a mapreduce job to the entire cluster (step 1 ). The new job ID (Application ID) is allocated by the Resource Manager (step 1 ). the client of the job verifies the output of the job, computes the split of input, and copies the job resources (including the jar package, configuration file, and split information) to HDFS (step 1 ). finally, submit

Report from unfamiliar to use

The room charging system has basically been completed, and the rest is the acceptance and correction. This blog focuses on how to learn and use reports when I print daily and weekly reports. In short, reports are dynamically displayed in tables, charts, and other formats. The formula can be used to represent: Report = diverse formats + dynamic data. It is like our previous bookkeeping. We can draw different charts based on our own needs and requireme

Blocking and suspending of threads

heavier, it may affect the control of the real-time task, and the system can suspend some unimportant processes to ensure the system can run properly.(4) The needs of the operating system. The operating system sometimes wants to suspend certain processes in order to check for resource usage or bookkeeping in the run.(5) The need to swap. To mitigate memory tensions, swap the in-memory blocking process to external memory.The following is the status of
