From an interesting thread at [WayBack] What’s the piece of Delphi knowledge you find yourself looking up over and over again? For me format strings is probably the thing that most stubbornly… – Lachlan Gemmell – Google+
- [WayBack] format strings
- Generics, as not much has changed in the docs since [WayBack] Overview of Generics or the linked articles:
- [WayBack] Declared Constants: Typed Constants
- File extenions with or without dot? The prefix period is included [WayBack] Delphi Basics : extractfilename command, but the file NAME does not include a prefix backslash:
- [WayBack] irregular syntax, for instance record constants
- [WayBack] variant parts in records
On the generics side, I have wrote a few bits in my blog before, often pointing to information by others (many by Stefan Glienke as his skills on this topic are beyond excellent):
- Delphi Constraints in Generics – RAD Studio XE documentation wiki
- Impossible: Property using Generics in Delphi. Interfaces/classes/methods/fields/constraints/type inferencing are
- How do I test an interface? Should I even do that? | Software on a String
- As Delphi generics are not supported for free functions, wrap them in a record container
- Workaround for Delphi 2010 compiler error “E2076 This form of method call only allowed for class methods” when it infers a generic parameter type
- The Default magic function in Delphi
- Reminder: rebuild my Nullable Types based on Class Operators in Delphi

- Delphi XE8 things I learned from the first week of G+ reading
- Delphi/Fortran memory allocation difference: row/column major order makes a big difference. StackOverflow answer
- Spring4D: How is the GlobalContainer intended to be used? Are there important don’ts?
- Delphi: do not mix interfaces and classes part X
- If you use Delphi or RAD Studio 10.2.2, ensure you have the latest one installed (build 2004) as it fixes some binary DCU incompatibility bugs

- Undocumented Delphi record alignment directive – Chee Wee’s blog: IT solutions for Singapore and companies worldwide
- Record helpers can do wonders for code clarity
- Delphi: ^TNodeData incompatible with PNodeData – {$T+} versus {$T-}
There are some very good books on Delphi though that dig deeper than the documentation:

How are you finding all these old Google+ URLs to be able to even look them up in the Wayback machine? Weren’t they all deleted a few years ago?

My blog queue is about 2 years deep, so I archived them (like any link) when G+ was still active.

Please keep it going then. They’re sometimes a bit out of date but they’re still mostly quite interesting. Particularly when you see your own name in the summary ;-)

I miss G+. Nothing like it emerged which is a real pity.
