question: what’s the difference and between CC and BCC and what’s the point of having both?
comment: Nobody except the sender and Blind Carbon Copy recepient know that the BCC recepient was given a copy of that message. Any address used in the Carbon Copy line will be shown to all recepients of the message, but it's understood that a message recieved as a CC is something you need to be aware of but aren't the primary subject(s) of.

   Primary development has been by Kent Overstreet, the developer of bcache, which he describes as a "prototype" for the ideas that became bcachefs. Overstreet intends bcachefs to replace bcache. Overstreet has stated that development of bcachefs began as bcache's developers realized that its codebase had "been evolving ... into a full blown, general-purpose POSIX filesystem", and that "there was a really clean and elegant design" within it if they took it in that direction. Some time after bcache was merged in 2013 into the mainline Linux kernel, Overstreet left his job at Google to work full-time on bcachefs.

   The term CO variant refers in general to CO, ECO, MVCO, or a combination of each of them with any relevant concurrency control mechanism or property (including Multi-version based ECO, MVECO). No other generalizing variants (which guarantee global serializability with no local concurrency control information distribution) are known, but may be discovered.

   CCA has been the subject of much controversy over the years, mostly related to apparent attempts to save money, such as hiring inadequate staff, extensive lobbying, and lack of proper cooperation with legal entities to avoid repercussions. CCA rebranded itself as CoreCivic amid the ongoing scrutiny of the private prison industry.

   Two major generalizing variants of CO exist, extended CO (ECO; Raz 1993a) and multi-version CO (MVCO; Raz 1993b). They as well provide global serializability without local concurrency control information distribution, can be combined with any relevant concurrency control, and allow optimistic (non-blocking) implementations. Both use additional information for relaxing CO constraints and achieving better concurrency and performance. Vote ordering (VO or Generalized CO (GCO); Raz 2009) is a container schedule set (property) and technique for CO and all its variants. Local VO is a necessary condition for guaranteeing global serializability, if the atomic commitment protocol (ACP) participants do not share concurrency control information (have the "generalized autonomy" property). CO and its variants inter-operate transparently, guaranteeing global serializability and automatic global deadlock resolution also together in a mixed, heterogeneous environment with different variants.
   In March 2011, CALGB merged with two other cooperative groups - the American College of Surgeons Oncology Group (ACOSOG)and North Central Cancer Treatment Group (NCCTG) to form The Alliance for Clinical Trails in Oncology. This was due to the call in April 2010 from the Institute of Medicine to strengthen and streamline operations among NCI clinical trials cooperative group programs. In June 2010, ACOSOG, CALGB and NCCTG integrated their statistical, data management and information technology functions. Having already merged some functions, the three groups began evaluating the possibility of full integration to further streamline operations, expand their scientific research opportunities, and apply for funding as a new, larger cooperative group.
   Designed around the nature and performance characteristics of SSDs, bcache also minimizes write amplification by avoiding random writes and turning them into sequential writes instead. This merging of I/O operations is performed for both the cache and the primary storage, helping in extending the lifetime of flash-based devices used as caches, and in improving the performance of write-sensitive primary storages, such as RAID 5 sets.
  
  bcache is licensed under the GNU General Public License (GPL), and Kent Overstreet is its primary developer.

   The Open Mind Common Sense project differs from Cyc because it has focused on representing the common sense knowledge it collected as English sentences, rather than using a formal logical structure. ConceptNet is described by one of its creators, Hugo Liu, as being structured more like WordNet than Cyc, due to its "emphasis on informal conceptual-connectedness over formal linguistic-rigor".

   Bcachefs
  
  bcachefs is a copy-on-write (COW) file system for Linux-based operating systems. Its primary developer Kent Overstreet first announced it in 2015, and efforts are ongoing to have it included in the mainline Linux kernel. It is intended to compete with the modern features of ZFS or btrfs, and the speed and performance of ext4 or XFS.

   The CVQ is based on a competency-based approach to training, assessment and certification. Candidates are expected to demonstrate competence in attaining occupational standards developed by practitioners, industry experts and employers. Those standards when approved by CARICOM allow for portability across the Region. Currently, CVQs are planned to reflect a Qualification framework of five levels. These are:
  
  BULLET::::- Level 1: Directly Supervised/Entry –Level Worker
  
  BULLET::::- Level 2: Supervised Skilled Worker
  
  BULLET::::- Level 3: Independent or Autonomous Skilled Worker

  BULLET::::- Level 5: Managerial and/or Professional Worker
   It was intended that CHS be brought into place upon each OCU/BOCU's transfer to the Central Communications Command. However, the system proved unstable and incapable of dealing with high call volumes and the old CAD system was kept in place. It is now intended that the two systems run in parallel until 2012.

   BCPL was first implemented by Martin Richards of the University of Cambridge in 1967. BCPL was a response to difficulties with its predecessor, Cambridge Programming Language, later renamed Combined Programming Language (CPL), which was designed during the early 1960s. Richards created BCPL by "removing those features of the full language which make compilation difficult". The first compiler implementation, for the IBM 7094 under Compatible Time-Sharing System (CTSS), was written while Richards was visiting Project MAC at the Massachusetts Institute of Technology (MIT) in the spring of 1967. The language was first described in a paper presented to the 1969 Spring Joint Computer Conference.
   The Clinical Care Classification (CCC), previously the Home Health Care Classification (HHCC), was originally created to document nursing care in home health and ambulatory care settings. Specifically designed for clinical information systems, the CCC facilitates nursing documentation at the point-of-care. The CCC was developed empirically through the examination of approximately 40,000 textual phrases representing nursing diagnoses/patient problems, and 72,000 phrases depicting patient care services and/or actions. The use of the CCC has expanded into other settings, and it is claimed to be appropriate for multidisciplinary documentation.
   In 1991, POSIX rigorously defined and standardized bc. Two implementations of this standard survive today: The first is the traditional Unix implementation, a front-end to dc, which survives in Unix and Plan 9 systems. The second is the free software GNU bc, first released in 1991 by Philip A. Nelson. The GNU implementation has numerous extensions beyond the POSIX standard and is no longer a front-end to dc (it is a bytecode interpreter).

  BULLET::::1. To obtain consistent methods and data for process and product development
  
  BULLET::::2. To help solve process engineering problems more efficiently
  
  BULLET::::3. To improve productivity of users by allowing sharing of common knowledge between different groups of people (using different tools within the integrated system) and finally
