Alembic is a database migrations tool written by the author of SQLAlchemy_. A migrations tool offers the following functionality:

• Can emit ALTER statements to a database in order to change the structure of tables and other constructs
• Provides a system whereby "migration scripts" may be constructed; each script indicates a particular series of steps that can "upgrade" a target database to a new version, and optionally a series of steps that can "downgrade" similarly, doing the same steps in reverse.
• Allows the scripts to execute in some sequential manner. The goals of Alembic are:
• Very open ended and transparent configuration and operation. A new Alembic environment is generated from a set of templates which is selected among a set of options when setup first occurs. The templates then deposit a series of scripts that define fully how database connectivity is established and how migration scripts are invoked; the migration scripts themselves are generated from a template within that series of scripts. The scripts can then be further customized to define exactly how databases will be interacted with and what structure new migration files should take.
• Full support for transactional DDL. The default scripts ensure that all migrations occur within a transaction - for those databases which support this (Postgresql, Microsoft SQL Server), migrations can be tested with no need to manually undo changes upon failure.
• Minimalist script construction. Basic operations like renaming tables/columns, adding/removing columns, changing column attributes can be performed through one line commands like alter_column(), rename_table(), add_constraint(). There is no need to recreate full SQLAlchemy Table structures for simple operations like these - the functions themselves generate minimalist schema structures behind the scenes to achieve the given DDL sequence.
• "auto generation" of migrations. While real world migrations are far more complex than what can be automatically determined, Alembic can still eliminate the initial grunt work in generating new migration directives from an altered schema. The --autogenerate feature will inspect the current status of a database using SQLAlchemy's schema inspection capabilities, compare it to the current state of the database model as specified in Python, and generate a series of "candidate" migrations, rendering them into a new migration script as Python directives. The developer then edits the new file, adding additional directives and data migrations as needed, to produce a finished migration. Table and column level changes can be detected, with constraints and indexes to follow as well.
• Full support for migrations generated as SQL scripts. Those of us who work in corporate environments know that direct access to DDL commands on a production database is a rare privilege, and DBAs want textual SQL scripts. Alembic's usage model and commands are oriented towards being able to run a series of migrations into a textual output file as easily as it runs them directly to a database. Care must be taken in this mode to not invoke other operations that rely upon in-memory SELECTs of rows - Alembic tries to provide helper constructs like bulk_insert() to help with data-oriented operations that are compatible with script-based DDL.
• Non-linear, dependency-graph versioning. Scripts are given UUID identifiers similarly to a DVCS, and the linkage of one script to the next is achieved via human-editable markers within the scripts themselves. The structure of a set of migration files is considered as a directed-acyclic graph, meaning any migration file can be dependent on any other arbitrary set of migration files, or none at all. Through this open-ended system, migration files can be organized into branches, multiple roots, and mergepoints, without restriction. Commands are provided to produce new branches, roots, and merges of branches automatically.
• Provide a library of ALTER constructs that can be used by any SQLAlchemy application. The DDL constructs build upon SQLAlchemy's own DDLElement base and can be used standalone by any application or script.
• At long last, bring SQLite and its inablity to ALTER things into the fold, but in such a way that SQLite's very special workflow needs are accommodated in an explicit way that makes the most of a bad situation, through the concept of a "batch" migration, where multiple changes to a table can be batched together to form a series of instructions for a single, subsequent "move-and-copy" workflow. You can even use "move-and-copy" workflow for other databases, if you want to recreate a table in the background on a busy system.

Natural language processing (NLP) is a subfield of linguistics, computer science, and artificial intelligence concerned with the interactions between computers and human language, in particular how to program computers to process and analyze large amounts of natural language data. The result is a computer capable of "understanding" the contents of documents, including the contextual nuances of the language within them. The technology can then accurately extract information and insights contained in the documents as well as categorize and organize the documents themselves.

Challenges in natural language processing frequently involve speech recognition, natural language understanding, and natural-language generation.

PowerShell is a cross-platform command-line interface and scripting language for system and network administration It is a command-line interface language. PowerShell is mainly influenced by Perl, AS/400 Control Language, and Python. PowerShell follows a programming paradigm of imperative programming, object-oriented programming, and functional programming. PowerShell is developed by Microsoft is designed by Jeffrey SnoverSupported by Microsoft Windows, Windows Server, and Ubuntu Operating Systems.

The most significant change in this version of PowerShell is the expansion to the other platforms. For Windows administrators, this version of PowerShell did not include any major new features. In an interview with the community on 11 January 2018, the PowerShell team was asked to list the top 10 most exciting things that would happen for a Windows IT professional who would migrate from Windows PowerShell 5.1 to PowerShell Core 6.0; in response, Angel Calvo of Microsoft could only name two: cross-platform and open-source.

According to Microsoft, one of the new features of PowerShell 6.1 is "Compatibility with 1900+ existing cmdlets in Windows 10 and Windows Server 2019." Still, no details of these cmdlets can be found it the full version of the changelog. Microsoft later professes that this number was insufficient as PowerShell Core failed to replace Windows PowerShell 5.1 and gain traction on Windows. It was, however, popular on Linux.

PowerShell Core 6.2 is focused primarily on performance improvements, bug fixes, and smaller cmdlet and language enhancements that improve the quality of life for users.

OCaml (formerly Objective Caml) is a general-purpose, multi-paradigm programming language that extends the Caml dialect of ML with object-oriented features. OCaml was created in 1996 by Xavier Leroy, Jérôme Vouillon, Damien Doligez, Didier Rémy, Ascánder Suárez, and others.

The OCaml toolchain includes an interactive top-level interpreter, a bytecode compiler, an optimizing native-code compiler, a reversible debugger, and a package manager (OPAM). OCaml was initially developed in the context of automated theorem proving, and has an outsize presence in static analysis and formal methods software. Beyond these areas, it has found serious use in systems programming, web development, and financial engineering, among other application domains.

The acronym CAML originally stood for Categorical Abstract Machine Language, but OCaml omits this abstract machine. OCaml is a free and open-source software project managed and principally maintained by the French Institute for Research in Computer Science and Automation (INRIA). In the early 2000s, elements from OCaml were adopted by many languages, notably F# and Scala.
