I have been away from ASUS for more than two months. Today I suddenly recall some things in ASUS. Although I do not like Asus's cultural atmosphere, I am a little proud of having worked in ASUS BIOS.When I first entered Asus, the bios I saw was a very different face-Ami. I usually use a lot of computers, and it is very common to deal with bios, but the domestic BIOS is still mostly award, and I do not know that there is

AWS provides a wide variety of mirrors for users, but in most cases the AMI provided in the community do not fully meet our needs, such as the more disgusting some mirrored root partitions are only 10g, so we generally use the community's public image to create a EC2, And then configure her, and then hit a mirror for the project, Packer can make us more automated to generate AMI, we can write the original i

For a computer-addicted user, the greatest pleasure is to discover the potential of the computer, understand some of the computer technology, the computer's BIOS settings for many of the first computer users is very abstruse, and even some of the old computer user does not know the BIOS, Because the computer BIOS involves a lot of computer internal hardware and performance margin settings, for the general people who do not understand the computer has a certain degree of danger, coupled with the

Hash tableA hash table (Hashtable), also known as a hash, is a collection of index key (key) and value pairs that are organized according to the hash program code of the index key (Hashtable). The Hashtable object is made up of a hash bucket (bucket) containing the elements in the collection. Buckets are virtual subgroups of elements within the Hashtable, making it easier and faster to find and retrieve jobs in most collections.A hash function is an a

partitions and buckets in the hive Hive the table into a "Partition" Partition. This is a mechanism for rough partitioning of tables based on the value of the partition column (Partition column, such as date), which speeds up the query speed of data fragmentation (Slice) using partitions Tables and partitions can be further divided into "buckets" (Bucket) it provides additional results for the data for mo
