This document discusses the key areas and concepts in the field of linguistics. It outlines the main branches of linguistics including diachronic/synchronic linguistics, general/descriptive linguistics, and contrastive/comparative linguistics. It also discusses the core areas of linguistics study including phonology, morphology, syntax, semantics, and pragmatics. Additionally, it examines related fields such as psycholinguistics, neurolinguistics, and sociolinguistics. Finally, it outlines several key concepts and properties of human language including modularity, recursion, discreteness, productivity, arbitrariness, and variability.
This document discusses various linguistic concepts related to sociolinguistics. It begins by explaining that language serves a social function in helping establish relationships and convey information about speakers. It then discusses the differences between language and dialect, as well as dialect and accent. Several key concepts are defined, including speech communities, communicative competence, linguistic variables, and constraints on linguistic variation. Methods of sociolinguistic data collection and analysis are outlined. Studies examining linguistic variation related to social factors are summarized. The concepts of style shifting, accommodation theory, dialect contact and levelling are also covered.
Mutual intelligibility refers to the extent that speakers of related languages or dialects can understand each other without special training. It is sometimes used as a criterion to distinguish languages from dialects, with dialects being mutually intelligible and languages not. However, this characterization is problematic, as some languages like Scandinavian tongues are mutually intelligible while some dialects of languages like German are not. Degree of mutual intelligibility and non-linguistic political/historical factors can also influence whether related varieties are considered languages or dialects. Mutual intelligibility is not an absolute criterion.

Ceph: A Powerful, Scalable, and Flexible Storage SolutionYashar Esmaildokht
## Ceph: A Powerful, Scalable, and Flexible Storage Solution
Ceph is an open-source, distributed storage platform that offers a range of features, including object storage, block storage, and file systems. It provides a highly scalable, reliable, and flexible solution for managing your data.
Ceph's Key Components:
* RADOS (Reliable Autonomic Distributed Object Storage): Ceph's core storage component. It provides object storage capabilities and forms the basis for other services.
* RBD (RADOS Block Device): Ceph's block storage service. Allows you to create and manage block devices that can be attached to virtual machines or containers.
* CephFS (Ceph File System): Ceph's distributed file system. Offers scalable and reliable shared file system access for applications and users.
Ceph Backfill:
Backfill is a process used to repopulate data onto newly added OSDs (Object Storage Devices) in a Ceph cluster. Here's how it works:
1. Data Imbalance: When new OSDs are added, the cluster may have an imbalance in data distribution. Some OSDs might have more data than others.
2. Backfill Process: Ceph identifies the underutilized OSDs and starts copying data from overloaded OSDs to these new OSDs.
3. Data Balancing: The backfill process aims to achieve an even distribution of data across all OSDs in the cluster.
Ceph Scrub:
Scrubbing is a data integrity check that Ceph performs to detect and repair errors in stored data. Here's the process:
1. Data Verification: Ceph compares the data stored on different OSDs that hold replicas of the same object.
2. Error Detection: Any discrepancies between the data replicas are flagged as errors.
3. Data Repair: Ceph attempts to repair the errors by copying the correct data from another OSD.
Ceph Erasure Coding (EC):
Erasure coding is a technique used to increase data resilience and reduce storage overhead in a Ceph cluster.
* Data Chunking: Data is divided into smaller chunks, and a parity chunk is generated.
* Data Distribution: These chunks and parity chunks are distributed across multiple OSDs in the cluster.
* Data Recovery: Even if some OSDs fail, the lost data can be recovered from the remaining chunks and parity chunks.
Benefits of EC:
* Increased Data Resilience: Can tolerate more OSD failures without losing data.
* Reduced Storage Overhead: Reduces the total storage capacity required for storing data replicas.
* Improved Performance: Can enhance performance by spreading the data load across more OSDs.
Understanding Ceph, backfill, scrub, and EC is crucial for efficient operation and maintenance of a Ceph cluster. These mechanisms ensure data integrity, availability, and scalability, making Ceph a robust and powerful solution for storage management.
این کتاب با هدف آشنایی با node.js و Express اختصاره به توضیح موارد مقدماتی درباره توسعه اپلیکشن Node.js و Express می پردازد و روش تالیف این کتاب مشابه آموزش های “Hello World” می باشد .
ویژگیهای داکر که میتواند فاصله بین نوشتن برنامه تا لحظه قرارگیری برنامه در محیط عملیاتی را به میزان قابل توجهی کاهش دهد و قابلیت تحویل سریعتر نرم افزار را بسیار افزایش دهد.
سرفصل مباحث:
- معرفی مفهوم Container و Containerization
- معرفی Docker - مزایا و معایب Docker
- چالش ها و فرصت های استفاده از Docker
- معرفی اولیه مفهوم CI/CD
