Foreign media found that 2015 MacBook Air is really able to achieve the laptop external 4K monitor. At the time of release, Apple had said that a new generation of MacBook Air could support an 2560x1600 resolution of an external monitor, with no mention of 4K. But the latest test is that the 2015 MacBook Air can support the Dell p2415q 24-inch 4K display, and th

How about 3 millet TV?Millet TV 3 uses a 60-inch LG True 4K screen, all-metal ultra-thin fuselage design, with diamond-colored aluminum frame, the upper thickness of 11.6mm, the lower thickness of 36.7mm. Equipped with 6M60 independent image processing chip, can eliminate the drag-tail phenomenon in the motion picture.The reason for the new generation is that the Millet TV 3 using split-style design, host and screen completely separate, support to upg

I. Paging Storage management 1. Basic Ideas The address space of the user program is divided into several fixed-size areas called "pages", where the memory space is divided into several physical blocks, and the size of the page and block is equal. Any page of the user program can be placed in any piece of memory to achieve a discrete allocation. Address agencies for paging storage management 15 12 11 0 Page number p page Internal Displacement amount W Page number 4 bits, each

of a file. EXT3/EXT4 file system, a file must occupy at least one inode and one block. (file size is larger) EXT3/EXT4 file system, normally a file is occupied and can only occupy one inode (person and ID number) Blocks are used to store actual data, and each block is typically 1k,2k,4k in size. The boot partition is 1k, and the other normal partitions are 4K (CentOS6) If a file is large (h

in a chessboard of 2kx2k squares, a square is different from other squares, calling it a special square and calling it a special chessboard. problem: Use 4 different forms of L-shaped dominoes to cover all squares except special squares on a given special chessboard, and any 2 must not overlap. There are 4k cases where special squares appear on the board. Thus, for any k>=0, there are 4k different special c

in general, the Nginx configuration file is useful for optimization comparisons in the following items:worker_processes 8;Nginx Process number, it is recommended to follow the number of CPUs specified, usually a multiple of it. worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000;Allocate CPUs for each process, in the example above, allocate 8 processes to 8 CPUs, or you can write more than one, or assign a process to multiple CPUs.worker_rlimit_nofile 1024

space, because 5 is within the [1~8] interval, so slot[0] is responsible for the allocation of the memory, but the limit of the interval [1~8] is 8, so even if the application 5 bytes, but still allocate 8 bytes to the application process. And so on: If the application is 12 bytes, 12 is in the interval [9~16], the upper limit is 16, so the slot[1] allocates 16 bytes to the application process, if the application 50 bytes, 50 is in the interval [33~64] between the upper limit of 64, so by slot[

;How the Inode works:The file is composed of metadata and data content, the metadata is stored in the Inode table, and the data content is stored in the data blockIn the Inode table in addition to the metadata, there are pointers, the pointer is the path of the data blockDirect pointer: The direct pointer has 12, points to 12 data blocks, the data block is generally the default 4k, so the direct pointer to theis less than the 12*

pages in the assignable space, and the process can refer to the description of Section 3.2. assignable space : slab logically divides the assignable space into M-memory pages with a size of 4K per page. Each page of memory corresponds to the members of the pages array, and each member of the pages array is responsible for allocating and reclaiming each memory page. wasted space : According to the size of each page

absolutely amazing, basic and Titan x equivalent. In the actual use, it in any game can be 1440p resolution, ultra-high quality to achieve 60fps frame number. Even for 4K games, it's OK to turn the picture to high, if you don't mind the number of frames around 40fps. The G-sync Monitor will be able to make up for the screen flaw in the lower frame, but the 4K g-sync display is not cheap, even the cheapest
