Rather than re-inventing the wheel, I’d suggest you to use some readily available solution. There are several expert systems out there and I’ll focus on those which are either in Python or can be used via Python. CLIPS CLIPS is an expert system originally developed by NASA. It’s considered state of the art and used … Read more
This is a known and documented deviation of GHC from the Haskell standard in default or Haskell 98 mode. GHC has a language extension called NondecreasingIndentation that can be used to trigger this behaviour. If enabled, a do keyword introduces a new block even if the next token starts at the same indentation level as … Read more
Although you’ve already got your own answer, I’ll point out a couple of things. You seem to be doing this in a very complicated manner. If you simply need to copy files into certain directories, write a debian/mypackagename.install with the following format: path/to/file/relative/to/source/root path/to/install/relative/to/system/root (do not prepend / before /usr, or /opt, or whatever your … Read more
Fanatics of all stripes should be questioned, no matter what topic they rave about. Data-driven decision tables are a perfectly good way to implement complex behavior. On the day it doesn’t scale or perform to your requirements, perhaps you’ll want to consider something else. I wouldn’t want to make a technology swap in working production … Read more
Just to clarify: not everyone agrees with the authors of StyleCop. Win32 and .NET guru Jeffrey Richter writes in his excellent book CLR via C#: The C# language specification states, “As a matter of style, use of the keyword is favored over use of the complete system type name.” I disagree with the language specification; … Read more
One of the use cases for RULES are updateable views (although that changes in 9.1 as that version introduces INSTEAD OF triggers for views) Another good explanation can be found in the manual: For the things that can be implemented by both, which is best depends on the usage of the database. A trigger is … Read more
Well, in broad strokes: If the name is preceded by ::, as in ::A or X::A, then use qualified name lookup. First look up X, if it exists (if not use the global namespace) then look inside it for A. If X is a class, and A is not a direct member, then look in … Read more
Freewind’s answer is pointing to a specific commit – now outdated. All rules are listed here https://eslint.org/docs/latest/rules/. from the list you can easily find the eslint:recommnded rules – as they are marked with this icon: ✅
Yes, it is written in a rather obvious way: TARGETS= file1 file2 file3 all: $(TARGETS) file1: dep1 dep2 file2: dep2 dep3 dep4 file3: dep2 dep1 $(TARGETS): cat $^ > $@ UPD. Just to clarify. Generic make rule looks like this: targets… : prerequisites… recipe … Any part of the rule can be omitted. Without the … Read more
Always leave the code a little better than when you found it.
