Parallel Programming Concepts (.NET related)

By -
Parallel execution - It's all about loaded computations.
Common Types of Parallelism
Data
    amount of data processed by one operation in parallel.
Patterns
    Parallel Loops
Implementations
    Parallel.Foreach
    Parallel.For
Task
    Some data or amount of data processed by many operations.
Patterns
    Parallel tasks
Implementations
    Parallel.Invoke
Dataflow
    Operations processed in some flow or order.
Patterns
    Features
    Pipeline
Embarrassingly parallel
    computations entirely independent of one another. No dataflow in between the options.

 Patterns
Parallel Loops
Parallel.For / Parallel.Foreach
Parallel Tasks
Parallel.Invoke
Parallel Aggregation
Map-Reduce
Producer-Consumer
By Parallel Loops with TLS (Task Local Storage) parameter
or by Wait All One By One
Futures
Dynamic Task Parallelism
Pipelines
+ Concurrent Data Structures.
Dataflow
(many to one + one to many, ContinueWhenAll)
+Concurrent Data Structures.
Speculative Execution
Wait All One By One
Facade Task (Threads saving by APM)

The TPL's main pattern-approach
Fork-join
Custom Partitioning Strategies
range (static)
stride (static)
chunk (dynamic)
hash (dynamic)

Convention over Git = CoG

By -
Convention over Git  or  CoG  influences on automated conflict solving during automated synchronization of remote Git repositories. Naming convention The Convention over Git uses naming to define owners of Git-branches. More often I use prefixed names for this. I.e. each remote Git repository owns its prefix. (It allows for all non-fast-forward Git-conflicts to be solved in favor of a prefix owner.) Examples Let's say one team uses prefix "company1/". (Git allows you have slashes in branch names) And another team uses "company2-". For this we may have flogging synchronized Git-branches. company1/develop vs company2-develop company1/JIRA-123 vs company2-JIRA-321 or simply company1/my-cool-feature company2-my-bug-fixing So, a naming convention in Git can be any conventional separation of names. It depends on you implementation. I use prefixes in my implementations. Results Conventions over Git gives many advantages and drastically ...

jQuery Deferred Object method chain or a Syntactic Sugar

The live samples: Chain animation Group async animation Piece of code: function doAnimation () { var duration = 2000; var host = jQuery(".host"); var img = host.children(); jQuery . when ( img .fadeOut(duration)) . then (function () { return host .delay(duration) .slideUp(duration) .delay(duration); }) . then (function () { return host .delay(duration) .slideDown(duration); }) . then (function () { return img .delay(duration) .fadeIn(duration) .delay(duration); }) . then (function () { // it3xl.ru: !The Recursion. doAnimation (); }) ; } I have the next thoughts. Prerequisites 1. The Deprecated and The Removed Let's omit all deprecated and removed functions, parameters, objects etс. See the documentation and be aware of it. Current version of the jQuery is the 1.9.1. 2. The Deferred is everywhere in the j...

Ctrl+Shift+Right arrow doesn't work in Visual Studio 2019

By -
Image
I can't select words to the right by using the standard shortcut Ctrl+Shift+Right arrow . By the way, words selection to the left with Ctrl+Shift+Left arrow works well. Probably, the ReSharper keyboard layout creates this trouble. I fixed it in Tools > Options window. Select Environment > Keyboard and past  Edit.WordNextExtend into the "Show commands containing" field. Then proceed as shown by the red arrows in the following image.
