Node. js framework StrongLoop Study Notes (1)Node. js framework StrongLoop Study Notes (1) I am using node. js is used as the mobile phone background, and the search framework finds that StrongLoop is quite suitable, but it finds that there are no Chinese tutorials. So when you study on your own, take a note, for reference by other people like me (my English level is very poor, I can only try it a little bit and record it. If you find any problem, please notify me to correct it, thank you !).

. This type of bad block is known as factory (masked) Bad block or initial bad/invalid block, which will be marked before the factory is released, It is marked as a bad block. (2) Bad blocks generated during use: The second type is generated during the use process. Because the use process takes a long time, an error occurs when the block is erased. This indicates that the block is broken. It must be found during the running of the program and marked as bad blocks. The location of the tag.

mechanical hard disk life is not ten years. The decision of SSD solid-state hard disk life is mainly determined by flash particle and solid-state hard disk capacity, SSD Flash granules are usually two kinds of MLC, SLC can read and write 100,000 times, and the MLC is only 10,000 times, so solid-state drives with SLC granules are more expensive, but their life expectancy is also better. For ordinary users

hundreds of physical servers. configuring each server with its own SSD may indeed help solve the IO bottleneck, however, it is not highly efficient to place it on the storage array. Do not use Tier 0 to solve network bottlenecks. If data transmission is controlled by the network, optimization of the storage system on the network backend will obviously not work well. Server-side SSD can reduce the need to access the storage system, thus reducing network traffic. Do not deploy a consumer-level SS

Preface:In the embedded development, such as uboot transplant, the kernel transplant all need to have the basic understanding to the flash. Here's a look at the relationship in Flash in the titleone, the memory storage structure of FlashFlash is divided into two types according to the internal storage structure:NOR FlashAndNAND Flash。Norflash is easy to use, easy to connect, can run code directly on the chip, excellent stability, high transmission rate, high cost performance in small capacity, w

You must ensure that hosts and IP address records are created within the DNS server. Select Create a self-signed certificate for SSL encryption and click Next This option is recommended only for testing or small-scale environments, otherwise select the first option to choose the certificate that is applied to the certification authority.Note: The steps to

the address 0010 H. to output any number of address cycles, the processor only needs to output the desired NAND address after the processor address is 0020h in sequence. Note that many processors can specify a number of time series parameters around the write signal of the processor, which is crucial to establishing a suitable time series. With this technology, you can directly access commands, addresses, and data from the processor without using any bonding logic. Multilevel Unit Each unit of

Problem encountered: The brush failed, the screen is not lit.Resolution: Found the embedded video to watch and solve.The reason for the original failure is. One is to choose the wrong file system of the corresponding file. SLC is the corresponding 256M Nandflash, and MLC is the corresponding 2G Nandflash. The second is to copy the superboot to the image directory. The third is the choice of Friendlyarm.ini. (For me, choose to correspond to the

capacity. The internal parts of the mechanical hard disk are more complex than the solid-state hard disk, there are no motors and fans inside the solid-state hard disk, so in this aspect the solid-state drive will have a great advantage over the mechanical hard disk, while the solid-state hard disk is much quieter than the mechanical hard disk in the work. In addition to the power consumption, solid-state hard drives are also lower than the traditional mechanical hard

disk working principle U disk's basic working principle is also relatively simple: USB port is responsible for connecting the computer, is the data input or output channel; The main control chip responsible for the coordination of the components of the management and release of various action instructions, and the computer will be identified as "removable disk", is a U disk "brain"; Flash chip and computer memory in the principle of the same, is the entity to save data, the characteristics of

time series. With this technology, you can directly access commands, addresses, and data from the processor without using any bonding logic. Multi-layer Unit Each unit of a multi-layer unit (MLC) is stored in two places, while the traditional SLC can only store one bit. MLC technology has significant density advantages. However, compared with SLC (table 3), MLC has lower speed or reliability. Therefore,

Due to SSD read/write latency and iops (I/O perSecond) These two aspects have about three orders of magnitude advantage over traditional mechanical hard drives, which has led some people to doubt the prospect of mechanical hard drives, I think SSD will be the first choice in the cloud computing era and will completely re

design software. RP-SLICEModule: The RP-slice module establishes an slice format interface between mimics and most RP machines. The RP-slice module can automatically generate the supporting structure required for the RP model. Fast and accurate data conversion for RP machines: The RP slice technology can be used to process large files and maintain a high resolution. When a sliced file is created, the resolution of the RP model is improved using a cubic Interpolation Algorithm. The patented mate
