For the attention of the graphics card gamers, this year's N card and a card is competitive, due to AMD launched RX 480 in cost-effective performance of eye-catching, attracted the attention of the players. Nvidia has also been forced to launch the GTX 1060 graphics card, the two new graphics cards are based on the new architecture, and are added to the VR feature, but also the positioning of high-end. Now the question is, GTX1060 and RX480 which is g

Network Coverage Assessment
For GSM network, the index of comprehensive evaluation network includes the absolute receiving level RX, which implies that the coverage level must meet the requirement of load-dry ratio (same frequency c/i≥9db, first neighbour-frequency c/i≥-9db), and for CDMA network, it comes directly from the Shannon formula of information theory, That is, directly measured by the load-dry ratio, including the front/back coverage st
field associated with the foreign key of the master table is updated, a four-level lock (S) must be applied to the sub-table; when the sub-table is indexed, when updating the foreign key association fields of the primary table, two levels of locks (RS) must be added to the sub-table ). When the child table already has RX, the S lock cannot be compatible, resulting in a blocking of updating the master table. If the sub-table does not have a lock, the

Why can't the last byte be read during continuous reading?
It is tested that this problem does not occur when the log is opened, so it can be confirmed that the delay at a specific location is insufficient.
By observing the waveform through the oscilloscope, we can see that the last byte has been read, and the Stop waveform is also displayed, therefore, it is determined that the last byte has not entered the FIFO before the last read of RX-
