The background is probably the story of a capitalist exploiting the residual value of a worker .... There is a piece of wood, cut it into several lengths, the cost of one cut is the length of the whole piece of wood cut, for example, if you want to cut a piece of wood with a length of 21 into 2 and 19 at a cost of 21, you can set the length and sequence of the two pieces by yourself. Idea: an obvious greedy idea is to cut down the longest board each time, so that the longest Board will not be us

role of cmos ram is to save the hardware configurations of the system and set certain parameters for users.Because the power consumption of cmos ram is extremely low, the backup battery on the cmos ram * motherboard can be powered off after the system power is off. Therefore, the user setting parameters stored in the CMOS will not be lost. Cmos ram is only a storage chip and only supports data storage. Special Programs are required for parameter settings in CMOS. The CMOS setup program of early

machine will easily crash during running. You can use special tools and software for troubleshooting. If the damage is serious, you can only replace the hard disk. In addition, for boards that do not support udma 66/100, you should pay attention to the setting of the hard disk running mode in CMOS. 2. software-related crashes [Improper software upgrade]Most people may think that the software upgrade will not be a problem. In fact, some components sha

Page 1st: one-stop teaching of General forum intrusion (figure) At present, there is a new trend on the Internet. The Hacker's attack targets have extended from the website to public places such as forums, chat rooms, and message boards, the Forum passwords of many users are exactly the same as those of e-mail and QQ, which poses a great threat to network security. In other words, hackers can gain higher permissions by intr

I used a simplified method here, but it was code simplification or the sub-governance recursion idea. One is divided into 4, until 2*2 can be solved directly. The placement of the four dominoes exactly corresponds to: dir [4] [2] = {0, 0}, {0, 1}, {1, 1}, {1, 0 }}; these four directions. The four directions can be used to determine the four directions of the incomplete position (top left, top right, bottom right, and bottom left ). Therefore, we can use a loop instead of judging the four directi

to create a sequence in a sequence adapter: Square sequence embedding. The adapter mode shows how to combine these two types. In the decorator mode, we want to add some out-of-the-box functions during the attack, such as digging holes and rolling boards on the hosts, so we don't have to worry about how to use the two irrelevant ones. We should first create an interface: Public interface work{Public void insert ();}　 Interface work has

Recently, some FPGA boards (ep4ce30f23c8n) were maintained, and we found that there were a pair of ground-to-ground short circuits for both 3.3v and 1.2v FPGA boards. After removing some chips powered by 3.3v, they were still short-circuited, there is no way to simply remove the FPGA chip. As a result, the short-circuit phenomenon disappears. It turns out that the FPGA 3.3v and 1.2v are short-circuited; F

When we conduct PCB cabling, we always face two or three kinds of situations on one board. The silly practice is of course, regardless of the case of November 21, copper is applied as long as it is the ground. This is not a problem for low-speed boards or boards that are insensitive to interference. Otherwise, the Boards may not work properly. Of course, if there

Question:On a dark, stormy night, the roof and doors of farmer John's cowshed were blown away. Fortunately, many cows are on vacation, so the cowshed is not full. The cowshed is lined up next to the other, and the ox stays in the room for the night. Some cowshed have cows, and some do not. All cowshed have the same width. Farmer John had to erect a new plank before the cowshed as soon as possible after the door was lost. His new timber supplier will supply him any length he wants, but the stingy
