1.PSD files for the Photoshop file format, the browser can not directly display, there is a need to generate a PSD file preview, Google for a few days did not find the available code, so that their own research, finally found a solution, the PSD is exported to a JPG file, Then generate thumbnails for them, which makes it much easier.

The concepts of dB and dBm are extracted from the data: dB and dBm are the units of power gain. The differences are as follows: 1. dB is a value that represents the relative value. The pure ratio only indicates the relative size relationship between two quantities, with no unit, when considering the number of dB whose power is larger or smaller than that of B, the following formula is used: 10 log (a power/B power). If the ratio of A to B is used, use 20log (a voltage/B voltage ). [Example] If t

LWE is a tool for wireless network configuration in Linux, including Kernel support, user-layer Configuration tool, and Driver Interface Support. At present, many wireless network cards support LWE, and mainstream Linux versions, such as RedHat Linux and Ubuntu Linux, have already brought this configuration tool.

1. DBM
DBM is the absolute value of power. The formula is: 10lgp (power value/1 MW ).
[Example 1] If the transmit power P is 1 MW, it is converted to dBm and then 0dbm.
[Example 2] for 40 W power, the converted value in dBm unit should be:
10lg (40 W/1 MW) = 10lg (40000) = 10lg4 + 10lg10 + 10lg1000 = 46dbm.

-point and point-to-point communication: A bluetooth device can form two types of networks in a specific way: a micro-Network (piconet) and a distributed network (scatternet). The establishment of a micro-network starts with the connection of the two devices, A maximum of eight devices can be used. In a micro-network, there is only one master device, and the rest are slave devices (slave). Different Master/Slave Device pairs can adopt different connection methods. In one communication, the conne

generally not more than 10 meters, but this does not mean that Bluetooth technology itself can only be used for short-distance transmission. As Bluetooth and WiFi are applied to the 2.4GHz frequency, the transmission distance is as much as 802.11b up to hundred meters. As shown in the table below, some Class 1 devices, due to the relatively high power consumption, can be transferred to a range of 100 meters if there is a steady supply of sufficient power. And our common mobile phones, headphone
Test instructionsThere are n nodes on a tree, numbered 1 to N, each with a weight of W. We will ask you to do something about this tree in the following form: I. Change u t: Changing the weight of the node U to t ii. QMAX U V: asks for the maximum weight of the node on the path from point u to v. Qsum u V: ask for the weights of nodes on the path from point U to V and note that nodes on the path from point u to v include U and V itselfExercisesThis is the tree chain to split the template problem
