Interesting take on Technical Debt: [WayBack] The Spilled Juice Analogy for Technical Debt | Disciplined Agile 2.X
Not just because of the analogy, but also because of this comment by Ramu Iyer:

TestInsight is a great tool for automatically running your unit tests and seeing the results to make you more productive.
Two of the results treeview features you might not know make you even more productive:
You can get TestInsight at sglienke / TestInsight — Bitbucket

Reminder to self: if you want to stay compatible with old (Pre Delphi XE) source code, then do not use virtual methods in class helpers.
Technically you can, as class helpers can inherit from other class helpers, but this is only supported as of Delphi XE.
In lower versions you get these errors as apparently the Delphi compiler tags an IInterface to the class helper compiler result:
[Error] Project1.dpr(14): E2003 Undeclared identifier: 'QueryInterface'
[Error] Project1.dpr(14): E2003 Undeclared identifier: '_AddRef'
[Error] Project1.dpr(14): E2003 Undeclared identifier: '_Release'

I never realised that Amazon Alexa has an open source account on GitHub: https://github.com/alexa
There are full instructions on getting a Java based Alexa Voice Service (AVS) – also used by Amazon Echo – to run on a Raspberri Pi (3 or better recommended, works on 2 as well) with this extra hardware:
Full instructions are at Raspberry Pi · alexa/alexa-avs-sample-app Wiki and a video is below: https://www.youtube.com/watch?v=baec1CbV6A0
I should find some time to try this out (:

Thanks [WayBack] gbabu for the below PowerShell ide
As PowerShell command:
Get-EventLog System | Where-Object {$_.EventID -eq "1074" -or $_.EventID -eq "6008" -or $_.EventID -eq "1076"} | ft Machinename, TimeWritten, UserName, EventID, Message -AutoSize -Wrap
Based on it and my own experience, thse Event IDs can be interesting:
You can also run this as a batch file, but not you need to escape the pipe | into ^| like this:
PowerShell Get-EventLog System ^| Where-Object {$_.EventID -eq "1074" -or $_.EventID -eq "6008" -or $_.EventID -eq "1076"} ^| ft Machinename, TimeWritten, UserName, EventID, Message -AutoSize -Wrap
If you have PowerShell 3.0 or greater, then you can use the [Archive.is] -In operator:
PowerShell Get-EventLog System ^| Where-Object {$_.EventID -in "41", "109", "1074", "6008", "1076"} ^| ft Machinename, TimeWritten, UserName, EventID, Message -AutoSize -Wrap

Interesting read:
Searching through logs and remoting to a machine to check it’s load is not a fun thing to do. This is why I’ve decided to look for a centralized logging service. And what I’ve chosen.
It looks like Microsoft App Insight is very much worth trying.

Recommented reading and playing: [Archive.is] Practical Color Theory for People Who Code which is not just about the colour wheel, but also about:

On a production system we had this error occurring without warning:
The cause was running out of private bytes or virtual size as they were almost 2 gigabyte which is too much for a 32-bit process:
The not so nice thing is that there were no memory warnings in the Firebird.log file at all.
In the client application the DAC (Data Access Layer) was getting lots of “unable to allocate memory from operating system” errors back from Firebird (and logging them in the client log file), so the client didn’t run out of memory: the server did.
This was with 2.5.2.26540 (at that time the most recent version) and it looks like more people suffer from this:
We put a monitor to watch the fbserver.exe process and warn us if it was reaching 1.5 gigabyte so we could re-start it before running out of memory.
