hard disk partitions, we know that the total number of primary partitions (including extended partitions) cannot exceed four, nor can we enclose extended Partitions between primary partitions. According to this principle, it is easier to divide hard disk partitions and reduce unnecessary troubles in the future; 1.

So how can we embark on the path to architects? This article analyzes the capability model of an architect. Can you be a good architect?==========An architect does not define a title that is technically competitive, but a title. The so-called title includes t

Architect's opinion The architect is the soul of a project team. He decides the technical selection, overall architecture, and module division of the entire system, and may also assume the role of communication with the leadership. In a sense, the architect determines the success or failure of the project to a large extent. The so-called train runs fast and relies entirely on the vehicle headband. Many outstanding architects have been transformed from

Overview: Linux users often find it difficult to identify the same type of device name, such as Eth0, Eth1, SDA, SDB, and so on. By observing the kernel device names of these devices, users usually know what type of device they are, but they don't know which device they want. For example, in a list of device names that are flooded with local disks and optical disks ( /dev/sd* ), users cannot find a disk with the serial number "35000c50000a7ef67". In t

and arbitration functions to ensure normal communication and prevent data destruction. Many Microcontroller (MCU) now have I2C bus interfaces, which can facilitate I2C bus design. For MCU without I2C bus interface, two I/O interface lines can be used for simulation/[2, 3/]. At present, some materials about simulation of I2C are mainly about communication in a single master node system, which makes the application of simulation of I2C bus have certain limitations. Based on the idea of bus arbitr

1 I2C communication protocol and S3C2410 chip Introduction I2C (Inter Integrated Circuit) bus was launched by Philips in 1980. The I2C bus transmits information between the bus and the device using two wires (SDA and SCL), serial communication between the microcontroller and external devices, or bidirectional data transmission between the master device and the slave device. The two communication lines are pulled up to + 5 V through the pull-up resisto

This article was first published by IEEE software and is now presented to you by infoq and IEEE Computer Society. In software engineering, there is a close relationship between nonfunctional requirements and software architecture (SAS. As early as 1994, Rick kazman and Len bass affirmed that there was a close relationship between software architecture and non-functional requirements. 1. This idea has been popular in the software development field for many years. It also explains why development

Service-Oriented Architecture) is a service-oriented architecture. This is the most frequently used word in a variety of technical journals in the past one or two years. Currently, many architecture designers and design developers simply equate SOA with Web Services, and think SOA is a kind of Implementation of Web Services. In essence, SOA represents a new system architecture. The emergence of SOA will have a huge impact on the design of the entire enterprise-level software architecture. 1. Wha

Today's architects and Architectures 　　 Introduction In the early days of the computer, around 1960, hardware was spent on software and dominated. After 40 years, we found that the situation had changed significantly. Due to industrial progress, the cost of hardware has dropped sharply. On the other hand, the cost of software development increases sharply due to the complexity of personalized enterprise-level application development.

Overview: Linux users often have difficulty identifying device names of the same type, such as eth0, eth1, sda, and sdb. By observing the kernel device names of these devices, users usually know what types of devices they want, but do not know which devices they want. For example, in a device name list filled with ephemeral disks and Fiber-Optic Disks (/dev/sd*), You cannot find a disk with the serial number "35000c50000a7ef67. In this case, udev can
