In the English language, the term "mutable" refers to the ability to change or be modified, while "immutable" denotes the opposite, meaning something that cannot be changed. When we talk about an "immutable object," we are referring to an object whose state or properties remain fixed and u...
Meaning, that the indexing of the elements would start from the last element. Here, we use indexes as −1, −2, −3, and so on, where −1 represents the last element. The following code block is an example of accessing elements using reverse indexing. Python 1 2 3 tup1= (...
As AshOS strives to be minimal solid and follow a LEGO like structure (start small, customize as you go), we primarily focus development on the base, meaning by default no Desktop Environment (not even Window Manager) is installed. This is by design as otherwise team has to support many ...
Constraints and/or definitions, such as the way in which data and transactions written to the cryptographically secured ledger are represented in the database table, how they interact relative to other objects in the cryptographically secured ledger, and/or the semantic meaning of any given row, ...
Since Immutable.js never directly mutates given data, it always needs to make another copy of it, performing multiple iterations like this can be very expensive. Seq is lazy immutable sequence of data, meaning it will perform as few operations as possible to do its task while skipping creation...
In a blockchain, data written to a block are immutable, meaning it cannot be changed. Through cryptographic hash functions and consensus algorithms, each block has a unique hash value, and only the majority of participating nodes agree to write it into the chain. Any change in the block will...
That means that almost all data corruption can be detected upon reading in the future; we aim to partition and replicate databases in the future. Copy-on-write semantics Similarly to the file systems Btrfs and ZFS, SirixDB uses CoW semantics, meaning that SirixDB never overwrites data. ...
The system will never enter an inconsistent state (unless there is hardware failure), meaning that unexpected power-off won't ever damage the system. This is accomplished without the overhead of a write-ahead log. (WAL) Log-structured and SSD friendly ...
