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

Delphi XE2 sanctuary lib galore…

Posted by jpluimers on 2016/11/02

Anyone who knows how to work around this? It happens every once in a while right after logging in over RDP to a VM with running Delphi XE2 (but similarly also in other Delphi versions like XE7):

---------------------------
Error
---------------------------
Access violation at address 74FD82A4 in module 'shell32.dll'. Write of address 00000014.
---------------------------
OK Details >>
---------------------------

With the below stacktrace including the sanctuary which always give me the creeps.

http://qc.embarcadero.com/wc/qcmain.aspx?d=139126 (which – like all IDE submitted bug reports – is private hence the copy at https://gist.github.com/jpluimers/6d8c0f29be107a83e48a5fd035900f74 ).

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.

OpenSuSE fix “piix4_smbus 0000:00:07.3: SMBus Host Controller not enabled!”

Posted by jpluimers on 2016/11/01

If you see this in journalctl after boot in a VM, then you likely want to disable piix4 smbus device detection:

Jul 07 23:02:47 revue systemd-udevd[507]: maximum number (136) of children reached
Jul 07 23:02:47 revue systemd-udevd[507]: maximum number (136) of children reached
...
Jul 07 23:02:47 revue systemd-udevd[507]: maximum number (136) of children reached
Jul 07 23:02:47 revue systemd-udevd[507]: maximum number (136) of children reached
...
Jul 07 23:02:47 revue kernel: piix4_smbus 0000:00:07.3: SMBus Host Controller not enabled!

The solution is to add one line to /etc/modprobe.d/50-blacklist.conf  (well: maybe [WayBack] add a comment line as well):

blacklist i2c_piix4

Comcast: a tool to similate network problems on BSD and Linux – tylertreat/comcast

Posted by jpluimers on 2016/11/01

At first I thought Comcast was a really good joke by Kristian Köhntopp, but it is actually a really cool open source tool with an appropriate name:

Comcast is a tool designed to simulate common network problems like latency, bandwidth restrictions, and dropped/reordered/corrupted packets.

It is written in go and works on BDS and derivatives (including Mac OS X). It could probably made to work on Windows too.

The source is on Github: tylertreat/comcast

Wow – people still working on Delphi 6 and 7 based code! Got new votes for answer to get rid of empty DDP files

Posted by jpluimers on 2016/10/27

Only Delphi 6 and 7 used DDP files (still a nice concept: diagrams to help understanding your DFM files)

A long time ago, I wrote a stackoverflow answer and later a blog post on how to find and get rid of empty DDP files as both Delphi versions had the habit of creating them:

The blog post was when I helped moving an ancient Delphi project to a more modern Delphi version (due to some personal stuff going on I never finished it) and I never used such old Delphi stuff again.

This week that answer got quite a bunch of upvotes on the stakcoverflow answer which means people are still using Delphi 6 and 7 based code. Who’d ever thought that 15 year old versions would still be used today?
