Very similar to “you get the best ideas while sleeping“:
[WayBack/Archive.is] Sasha Laundy on Twitter: “The best debugger ever made is a good night’s sleep.”

For me, taking a shower and contemplating during a commute are good debuggers too. But sleeping is still the best.
Hope you enjoyed Christmas, good luck on your debugging ventures!

For my link archive: [Archive.is] Flexible and Economical UTF-8 Decoder.
Be sure to read the whole article there as the explanation of the initial algorithm is important and final algorithm is towards the end.
The foundation is a state machine combined with a lookup table to find the initial state and proceed to subsequent states.

When learning Python, one of the terms to get used to is Pythonic, basically shorthand for a loosely defined idiomatic Python way of writing code.
Some links to help you get a feel for this:
The language’s core philosophy is summarized in the document The Zen of Python (PEP 20), which includes aphorismssuch as:[51]
- Beautiful is better than ugly
- Explicit is better than implicit
- Simple is better than complex
- Complex is better than complicated
- Readability counts
…
the Python philosophy rejects exuberant syntax (such as that of Perl) in favor of a simpler, less-cluttered grammar. As Alex Martelli put it: “To describe something as ‘clever’ is not considered a compliment in the Python culture.”
…
“there should be one—and preferably only one—obvious way to do it”
Sometime, I am going to dig into learning how to write Pythonic code for merging and joining dictionaries (preferably those of namedtuple entities). Hopefully these links will help me with that:

I don’t have enough time right now to elaborate on the code, so below is a an example of where I bumped into the very non-descriptive [WayBack/Archive.is] E2015: Operator not applicable to this operand type when using generics in Delphi.
Most have to do with comparing types (one of which is similar to comparing interfaces where you need to have a GUID in order to get an as comparison working, see Source: Delphi – Using FastMM4 part 2: TDataModule descendants exposing interfaces, or the introduction of a TInterfacedDataModule).
Like most post-Delphi 2007 language features in Delphi, generics still have rough edges. I doubt this will change anytime soon and I am not alone in this.
The documentation never got update to cover situations involving generics ([Archive.is] E2015 Operator not applicable to this operand type (Delphi) – RAD Studio), so basically this to show some examples you might bump into as well.
Note the code below usually is an indication of code-smell, as was the more elaborate situation I had to use it in. A long term solution for that code was to introduce more polymorphism.
A shorter term solution involves either the use of local variables or type-casting (for the latter, see [WayBack] delphi – Cannot compile constrained generic method – Stack Overflow)

Cross-functionality means having all the necessary people and skills on one self-organizing team. Unfortunately, the execution of cross-functionality is often biased. The main traps we fall into are misunderstanding the value of specialization, hero worship, and not “walking the cross-functional talk” as organizations. Let’s examine each of these pitfalls in the hope that your teams may avoid them.

These quotes remind me so much of a project from a while ago I rolled into and forgot to ask them if they not just nodded “yes” when I asked them “do you understand de concept of technical debt”?

On G+, Tom Field bumped in the [WayBack] issue that the IDE would add VCL units to the uses list when putting FMX controls on a form.
I’ve observed it the other way around as well, and there are two things you need to check:
FrameworkType element in your .dproj file
VCL or FMX values are allowed, but in the past more values were used, see Delphi .dproj files: FrameworkType and FormType.{$R *.dfm} for VCL or {$R *.fmx} for FMX.References:
{$R *.fmx}or{$R *.dfm}in the unit. You may be able to get away with renaming the.dfmfile to.fmx,and changing the directive in the unit..dprojfile tells you what kind of application it is (FMX or VCL) in theFrameworkTypeelement and the IDE should respond to that correctly.
