Far less active on blog on social media: some personal things that need to be done.

Posted by jpluimers on 2019/04/03

Some people already noticed me being far less active on social media including this blog.

This will continue for a while, as I am supporting two people that are very dear to me.

  • One needs to get some MRI scans very soon, with past results not being promising, so consequences not clear yet.
  • Another I am protecting from mental abuse by somebody close, something which is very hard to prove, but has very real consequences. Recognising the – initially very subtle – behavioral changes, and convincing other people up the supporting and medical tree they were indeed true and related, took several years, so I recon the recovery process will take long too.

Luckily, my blog queue has been filled with about 2 years of content, so that will run automatically.

Social media response from me will be on a “when I feel like it” base until further notice, focussing on things that give me energy and bring me joy.

The biggest lie I tell myself is not about new years resolutions.

Posted by jpluimers on 2019/01/01

The biggest lie I tell myself is “I don’t need to write that down, I’ll remember it”

It’s likely older, but the oldest reference I could find was 2012 [WayBack].

So before I forget:

Happy New Year everyone!

With the above quote, it is no coincidence I started my blog even earlier (in 2009): it’s my off-line memory, way better readable than my hand-writing and indexed by various search engines.

Delphi RTTI Context limitation: not thread safe for method RTTI

Posted by jpluimers on 2019/07/16

In a comment to [WayBack] Update: It was not clear what I was asking so I updated the question. I am trying to call RTTI Invoke from within TTask.Run and I get an AV. I have t… – John Kouraklis – Google+

Design Patterns & Refactoring

Posted by jpluimers on 2019/07/16

Design Patterns and Refactoring articles and guides. Design Patterns video tutorials for newbies. Simple descriptions and full source code examples in Java, C++, C#, PHP and Delphi.

Source: [WayBackDesign Patterns & Refactoring.

And indeed a lot of examples in Delphi too; few sites have that: Delphi site:sourcemaking.com.

PowerShell: $args variable outer scope has command-line arguments – about_Automatic_Variables | Microsoft Docs

Posted by jpluimers on 2019/07/16

I always forget the exact syntax for getting command-line arguments to PowerShell. It’s the $args implicit array variable:

Not sure why yet, but sometimes ping and nslookup cannot reverse lookup a machine by IPv4, but tracert can

Posted by jpluimers on 2019/07/15

A while ago I had a situation that when doing a ping or nslookup on an IPv4 address in Windows, it would not show the name through reverse lookup, but tracert could.

It is not quite the same as what happened in these posts:

This post is basically a place to put notes in when this ever happens again.
