Google data centers. Google data centers are the large data center facilities Google uses to provide their services, which combine large drives, computer nodes organized in aisles of racks, internal and external networking, environmental controls (mainly cooling and humidification control), and operations software (especially as concerns load ...
Python Imaging Library is a free and open-source additional library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats. It is available for Windows, Mac OS X and Linux. The latest version of PIL is 1.1.7, was released in September 2009 and supports Python 1.5.2–2.7.
This is a list of file signatures, data used to identify or verify the content of a file.Such signatures are also known as magic numbers or Magic Bytes.; Many file formats are not intended to be read as text.
Consistent hashing. In computer science, consistent hashing[ 1][ 2] is a special kind of hashing technique such that when a hash table is resized, only keys need to be remapped on average where is the number of keys and is the number of slots. In contrast, in most traditional hash tables, a change in the number of array slots causes nearly all ...
At all times the algorithm only needs to remember two values: the sum of all the elements so far, and its current position in the input list. Therefore, it is said to have a space requirement of O ( 1 ) {\displaystyle O(1)} , if the space required to store the input numbers is not counted, or O ( n ) {\displaystyle O(n)} if it ...
Rainbow table. A rainbow table is a precomputed table for caching the outputs of a cryptographic hash function, usually for cracking password hashes. Passwords are typically stored not in plain text form, but as hash values. If such a database of hashed passwords falls into the hands of attackers, they can use a precomputed rainbow table to ...
Google Drive is a file-hosting service and synchronization service developed by Google. Launched on April 24, 2012, Google Drive allows users to store files in the cloud (on Google servers ), synchronize files across devices, and share files. In addition to a web interface, Google Drive offers apps with offline capabilities for Windows and ...
The MD5 message-digest algorithm is a widely used hash function producing a 128- bit hash value. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function MD4, [3] and was specified in 1992 as RFC 1321. MD5 can be used as a checksum to verify data integrity against unintentional corruption. Historically it was widely used as ...
