From a long time ago, but got a request for it a while ago is [WayBack/Archive.is] Howto create C-Header for Delphi/Free Pascal/Lazarus DLL – data types – Stack Overflow:
I have used the below construct to generate header files compatible with the C-mode compiler of Visual C++ 6 from Delphi 5 code when Delphi had the -JPH switch (see notes below).
Note that I have not used this since Delphi 5, but the switch has since then been expanded:
Somewhere along the line, the [
WayBack]
JPHNE switch has been added to the
dcc32 command-line compiler:
-JPHNE = Generate C++ .obj file, .hpp file, in namespace, export all
It generates the .hpp files to import the DLL that was written in Delphi.
Notes from the Delphi 5 era:
{ Visual C++ 6 does not like nested structs/unions the way that BC++ can handle them.
Visual C++ 6 requires the "typedef" to be present AND the typename AFTER the struct definition.
You will see this when defining TConversationId, TReturnKey and other types that depend on nested structs/unions
The trick is to perform these steps each and every time this unit changes:
- Generate this unit once with all the EXTERNALSYM disabled.
- Then the DCC32 -JPH will generate the basic structs for them.
- Copy all the nested struct and union definitions to this file
- Embed the definitions with (*$HPPEMIT '' *)
- Append the typename at the end of the struct definition
- Enable all the EXTERNALSYM again
- Regenerate the HPP files by using DCC32 -JPH
To make this process easier, we have introduced two new conditional defines:
- BCB - disable EXTERNALSYM, disable HPPEMIT
- VC6 - enable EXTERNALSYM, enable HPPEMIT
A similar thing is with these constructions that VC6 does not like those either:
- short strings (BCB defines them as "SmallString<##>" which VC6 does not like).
- short integers (BCB defines them as "Shortint" so we have included an HPPEMIT for that)
}
{$ifdef win32}
{ important! Makes sure that the all enumerated types fit in exactly one byte each! }
{$Z1}
{ force the C/C++ HPP header files to have the C/C++ compiler pack structure elements on byte boundaries }
{$ifdef BCB}
{$HPPEMIT '#pragma option push -a1' }
{$endif BCB}
{$endif win32}
And the download (hopefully I have converted it to git by then):

For my future self.
Due to an issue with choco-cleaner versions [WayBack] 0.0.6 and [WayBack] 0.0.7, I needed to ensure it was installed as version [WayBack] 0.0.5.2 and keep it that version.
Not sure if this is the canonical way, but this worked:
choco uninstall --yes choco-cleaner
choco install --yes choco-cleaner --version 0.0.5.2
choco pin add --name=choco-cleaner --version 0.0.5.2
choco pin list
This worked to revert:
choco pin remove --name=choco-cleaner
choco pin list
choco upgrade --yes choco-cleaner
Aftere this upgrade, choco-cleaner version 0.0.7.1 shows a nice error message when the environment variable %ChocolateyToolsLocation% fails to exist.
In that case calling RefreshEnv.cmd will create that environment variable.

I bumped in the error [WayBack] “The input object cannot be bound to any parameters for the command either because the command does not take pipeline input or the input and its properties do not match any of the parameters that take pipeline input.” when using [WayBack] Write-Output where [WayBack] Select-Object worked just fine.
This happened when playing around with detecting empty Chocolatey .nupkg package files.
$LibPath = Join-Path $env:ChocolateyInstall 'lib'
$NupkgFilter = '*.nupkg'
Get-ChildItem -Path $LibPath -Recurse -Filter $NupkgFilter |
Where-Object {($_.Length -eq 0) -and ($_.BaseName -eq "hg")} |
Sort-Object LastWriteTime |
Select-Object BaseName
<#
Get-ChildItem -Path $LibPath -Recurse -Filter $NupkgFilter |
Where-Object {($_.Length -eq 0) -and ($_.BaseName -eq "hg")} |
Sort-Object LastWriteTime |
Write-Output BaseName
## Write-Output : The input object cannot be bound to any parameters for the command either because the command does not take pipeline input or the input and its properties do not match any of the parameters that take pipeline input.
#>
Get-ChildItem -Path $LibPath -Recurse -Filter $NupkgFilter |
Where-Object {($_.Length -eq 0) -and ($_.BaseName -eq "hg")} |
Sort-Object LastWriteTime |
ForEach-Object { Write-Output $_.BaseName }
The output is also slightly different, hinting on the root cause:
BaseName
--------
hg
hg
The above shows that Select-Object selects a list of BaseName properties (italic part), whereas Write-Output shows a single BaseName property content (bold part).

It’s mainly written in JavaScript and Java with a PostgreSQL database and elasticsearch search.
There is plenty of [WayBack] metasfresh documentation (for users, administrators and developers), all with markdown source.

A while ago, This does not compute had a few nice videos on a Mac SE/30 and it’s repair, including the recap process of replacing the electrolytic capacitors (or condensators in some other languages), and cleaning the board (some wash it with hot water and soap, others with isopropyl-alcohol, often called rubbing alcohol).
Note the simasimac can have many causes: bad capacitors in main board are the most common, but it can also be bad memory.
White lithium grease can make the floppy work again (see also [WayBack] Lithium soap – Wikipedia and [WayBack] Grease (lubricant) – Wikipedia).

The ROM SIMM comes pre-programmed with a BMOW-made custom ROM containing the following changes:
- ROM disk provides a diskless booting option
- HD20 hard disk support built-in
- 32-bit clean – allows use of System 7.6+ and more than 8MB RAM
- Memory test is disabled for faster booting on 16MB+ systems
- Customized startup chime – major 9th arpeggio
- Happy Mac icon is replaced by a color smiling “pirate” Mac
- New startup menu screen displays installed RAM, addressing mode, and ROM disk details

The SE/30 is probably the most popular candidate for recapping. Unfortunately, it’s also one of the more difficult to revive as the leaked electrolyte easily damages traces and vias on these boards. Be sure to wash these boards very well and inspect closely for broken or rotten traces.

Notes
Desolder can be tricky, especially for surface mount. This helps:
- Add some fresh 60/40 solder to the joints with a solder gun (as modern solder is lead free, whereas past solder contained lead)
- Carefully heat up the component and surrounding area with a heat-gun
Choosing capacitors:
Soldering: always add some fresh solder on the pads before soldering surface mount (SMD) capacitors.

Hopefully this becomes available on-line, as this will be a great talk, but Potsdam is out of my reach in my current physical condition.
[Wayback] AgileTD Keynote | Happiness is Quality
In Gwen Diagram’s keynote go on a journey of looking at how to improve happiness in teams for the goal of building quality systems.
How can we build teams that strive to build quality systems? By building in happiness early and often.
Each organisation has a culture which directly affects the quality of their work. Organisations with a lower level of quality; that is, systems that fail more often, longer times to fix and longer times to build often have a few things in common; frustration, apathy and cynicism.
On the other side of the coin, teams with slack, time to learn and time to reflect also have the space to improve their systems. Quality is everyone’s responsibility is an oft quoted phrase. But, how do you actually engage people to build quality systems?
Improving quality should not weigh heavy on the shoulders of the test specialist. Their main role should not be attempting to convince people that unit tests should exist, that systems should be testable and observable or that automated tests will speed up development. Instead, we should be building teams that want to find out together how to build a system that breathes quality.
The way to do this is by improving the happiness of the engineers on the team with learning, autonomy and coaching. So, how can we build teams that strive to build quality systems? By building in happiness early and often. In this talk, we will go on a journey of looking at how to improve happiness in teams for the end goal of building quality systems.
