Unity IoC container: tips, tricks and dirty hacks

Posted by jpluimers on 2016/11/03

The #Fellows | Unity IoC container: tips, tricks and dirty hacks post is a very readable and to-the-point introduction to Unity IoC focussing on Dependency Injection. Implementation details of various IoC/DI frameworks differ, so some keywords:

  • Container
  • InjectionConstructor
  • InjectionProperty
  • Inversion of Control
  • Named registration (or keyed registration)
  • PerResolveLifetimeManager
  • Register
  • RegisterType
  • Resolve
  • ResolvedParameter

nst/JSONTestSuite: A comprehensive test suite for RFC 7159 compliant JSON parsers

Posted by jpluimers on 2016/11/01

Cool: nst/JSONTestSuite: A comprehensive test suite for RFC 7159 compliant JSON parsers

Which is the result of the presentation seriot.ch – Parsing JSON is a Minefield 💣[WayBack]

Both the tests and presentation are well worth reading.

The graph gives me ambivalent feelings and make me wonder how various .NET and Delphi based JSON parsers stack up.

I wonder how Delphi and C# libraries stack up against these results especially since questions like What is the best JSON library to use for Delphi 10.1? To read and write JSON. – Godfrey Fletcher – Google+ [WayBack].

Hopefully the results by David Berneda will be published soon: I’ll do a quick test with TeeBI json import and the different libraries (System.Json, SuperObject etc)

Edit: Stefan Glienke mentioned he wrote a DUnit testsuite at http://pastebin.com/k5ktBxh9 [WayBack] that shows the built-in TJSONObject [WayBack] parser fails at least 25 of the tests.

If you thought you could do multi-threading, then play “The Deadlock Empire” games

Posted by jpluimers on 2016/10/04

Slay dragons, learn concurrency! Play the cunning Scheduler, exploit flawed programs and defeat the armies of the Parallel Wizard.

Source: The Deadlock Empire

Via: Face the dragon. Learn the ropes of concurrent programming. – Lars Fosdal – Google+

Source code is available and focuses on C#; maybe one day I’ll make a Delphi version: deadlockempire/deadlockempire.github.io: The Deadlock Empire: Slay dragons, learn concurrency!

BTW: a great book (with nice illustrations at both github and kernel.org) is Source: Is Parallel Programming Hard, And, If So, What Can You Do About It? [WayBack]

Yes Dorothy, the .NET System.Array Class can throw you a NotSupportedException

Posted by jpluimers on 2016/09/21

It’s been in the System.Array class forever, but remarkably few people do know that it can throw you a NotSupportedException (for instance when calling Add, Insert, Remove, etc).

It does because it implements IList, but not all methods implemented from IList are valid.

And it also indicates that, as the IList Properties allows for IsFixedSize to return false.

A similar case is there for IsReadOnly: then you cannot even modify the values.

Ever since I started teaching .NET/C# classes almost 15 years ago, I warned:

beware when you use IList as not everybody implements all methods.
