Next use SECURECRT software, test the higher baud rate, see is reply what? The 9600 baud rate is problematic with the internal crystal oscillator when using STM32. However, if the baud rate is biased, then why only the 5th notify have problems? So the idea was blocked at the time.4. There may be a situation in which t

2 Hard drive prices are too expensive: SAS drives are much more expensive than the same volume ultra-hardware SCSI hard drives. The high price has a direct impact on the number of users and the number of channels of digestion, and can not form a mass production of SAS hard drives, the cost of the pressure will in turn lead to price can not be reduced. If users want to make a simple raid level, they need not only bu

In fact, most raid damage is not from good to paralysis, most of which will pass the downgrade this step, so the actual forced reconstruction of the file system is not a good practice, but the downgrade to the paralysis during the period of time if the data write is not much, Repair file system may be rebuilt after the change that the movie star downgraded to paralysis during this period of time.

chart in Figure 1.9, the number of parts is doubled each year, and Moore added new data in 1975 and corrected the number of parts by 1 time times every 2 years. However, according to recent trends, it has been suggested that Moore's law should be a doubling of the number of parts every 1.5 years, but Moore himself has not said "1 time times more than 1.5 years"
Scaling Law
Moore's law is very well known, but many people may not know that the 1974 IBM Robert Dennard and other people's paper also

In fact, from the original computer to now only 60 years. The reason for the leap is that the progress of the circuit technology from the vacuum tube to the transistor to LSI is of course the greatest credit. On the other hand, the progress of computer architecture, which is attached to the speed of operation, has made great contributions.
Although processor performance has been evolving rap
with the same primary key hash value share the same partition in DynamoDB, the local level two index contains only items that are stored in the same location (the same partition). Therefore, LSI can be used to query items that have the same primary key hash value, but with different range keys.It is important to note that all the GSI related to the table must be specified when the table is created. A GSI index does not require that indexed properties
