hand" principle, they can support the P6 solution. So P6's solution is the only one: P1, P2, P4, one gold coin for each person, P6 took 97. In this way, the P9 solution is: P3, P5, P7, one gold coin for each person, and then select one of P1, P2, P4, and P6 to give two gold coins, p9 has 95 items. Finally, the P10 solution is the only one: P1, P2, P4, P6, p8, one gold coin per person, P10 get 95. 2) is the most interesting (note: we can return to the 50%-vote rule ). The reasoning process in th

only MBR, it is possible to create a multi-boot environmentThe EXT2 file system is basically differentiated into blocks (block group) when formatted, and each block group has a separate inode/block/superblock System. Each of the blockgroup is divided into six main parts:Data block: where to place the fileinodetable:inode table, where inode block each inode 128bytes, inode . inode the size is fixed 128bytes, But there are so many things to record, if a file is too large, then j

P178: The last 5th rows. reques_queue should be request_queue; the last 1st rows of reques should also be request. 23. In the last row of the P186 footer, shed. h should be sched. h. 24. Line 3 of P189 text, vm_area_struc should be changed to vm_area_struct. 25. In row 7th of P193, stask_struct should be task_struct. 26. In section 13.5 of P196, mummap () and do_mummap () s

traditional signal processing signal?21. how to read and write hard disks?When a program needs to read and write data, it first sends an application to the buffer management program. If the buffer zone already exists, it directly returns the buffer header pointer to the program and wakes up the program process. Otherwise, ll_rw_block () will be called ().How can I ensure that all requests are processed in the request list?Ll_rw_block () uses make_request (); then, in make_request (), add_reques

detailed explanation p202 page.If you write the method, it will be recycled:Reference{byte B = new BYTE[6 * 1024 * 1024];}int a = 0;So the garbage collector will recycle it right away.Reason: The slot in the local variable table is reusable, the scope of the variable defined in the method body does not necessarily overwrite the entire method body, and if the value of the current bytecode's PC counter has exceeded the scope of the entire variable, the

scheduling. Signal Volume semaphoreP:proberen TestV:verhogenThe key to semaphores is their atomic execution. For shared array teams, the sequential process of a group of collaborations must provide mutual exclusion. One workaround is to ensure that only one process or thread can use a critical section of code at some point.The main disadvantage of critical area solutions is that they all need to be busy and so on. The signal volume can overcome this difficulty. A variety of synchronization prob
