@trichoplax Shog9 has already been informed about it in the moderator chatroom. Because of today being Sunday though, I don't expect an answer about it quickly.
Meanwhile, this is an interesting read:
Scunthorpe problem
The Scunthorpe problem is the blocking of e-mails, forum posts or search results by a spam filter or search engine because their text contains a string of letters that are shared with an obscene word. While computers can easily identify strings of text within a document, broad blocking rules may result in false positives, causing innocent phrases to be blocked. == Origin and history == The problem was named after an incident in 1996 in which AOL's profanity filter prevented residents of the town of Scunthorpe, Lincolnshire, England, from creating accounts with AOL, because the town's name contains...

@SimonForsberg Thanks - I had heard of that, it's an interesting problem. Since there aren't a long list of languages containing this word I'm guessing it's just a matter of adding bf to the list of blocked words

PeteIf you've got local source code you want to add to a new remote new git repository without 'cloning' the remote first, do the following (I often do this - you create your remote empty repository in bitbucket/github, then push up your source) Create the remote repository, and get the URL such as...

I think a lot of people think "hey, great, there's this library", but never stop to think that they might have to maintain it themselves.
You always run the danger of ending up with your own fork.

@Mast I'm looking for something a bit different from this. Assume the repo is already set up (before you were hired) and you know absolutely nothing about source control. You need a very basic tutorial for checking out, branching, checking in, merging, etc., etc., etc...

That video is roughly "Haskell is better than Java because function programming is better than imperative programming. Also, I can't even really write a Java for loop that does what I say it does. And I'm saying this thing is global regardless of context, which isn't really true."

I'm having a DRY problem here, mind if I interrupt? 
private void AnalyzeCSharpSymbol(SyntaxNodeAnalysisContext context)
{
    var attributeExpression = context.Node as Microsoft.CodeAnalysis.CSharp.Syntax.AttributeSyntax;

    if (attributeExpression?.ArgumentList == null || attributeExpression.ArgumentList.Arguments.Any())
    {
        return;
    }

    context.ReportDiagnostic(Diagnostic.Create(Rule, attributeExpression.GetLocation()));
}

private void AnalyzeVisualBasicSymbol(SyntaxNodeAnalysisContext context)
{
    var attributeExpression = context.Node as Microsoft.CodeAnalysis.VisualBasic.Syntax.AttributeSyntax;
Those methods are identical except for the cast type (and that should really be a cast at the top instead of an as).

Your two methods can still exist, but they just call that one.
Why can't you?
 
Hosch250
Hosch250
4:30 PM
Because this is how I call them: 
public override void Initialize(AnalysisContext context)
{
    context.RegisterSyntaxNodeAction(AnalyzeCSharpSymbol, Microsoft.CodeAnalysis.CSharp.SyntaxKind.Attribute);
    context.RegisterSyntaxNodeAction(AnalyzeVisualBasicSymbol, Microsoft.CodeAnalysis.VisualBasic.SyntaxKind.Attribute);
}

That's not calling what you just showed.
 
Hosch250
Hosch250
The signature is fixed - I can't touch that.
 
nhgrif

I'm not telling you to change the signature.
Your two methods are wrappers for one with the signature I just posted.
 
Hosch250
Hosch250
Oh, OK.
 
nhgrif
nhgrif
That's a pretty common technique.
It's like convenience constructors
You have one constructor with two arguments
And then ten constructors with 1 argument that call the first one with the passed in argument and a predefined second argument. 
enum FooBar {
    case Foo, Bar
}

func foo(arg1: Int) -> Bool {
    return fooBar(arg1: arg1, arg2: .Foo)
}

func bar(arg1: Int) -> Bool {
    return fooBar(arg1: arg1, arg2: .Bar)
}

private func fooBar(arg1: Int, arg2: FooBar) -> Bool {
    // 90% common code, and checking arg2 for divergent areas
}

I don't know what's idiomatic in Brainfuck or not, but well... when it comes to somewhat complex things (as much as you can call Fizzbuzz complex...), it tends to require a whooooole lot of loops and additions and subtractions... so, I guess it's idiomatic.
 
Hosch250
Hosch250
@nhgrif I don't see how I can do that since everything depends on the one variable.

@SimonForsberg Because it has a whole lot of loops, additions and subtractions, it's idiomatic. Flawless logic.
What could possibly go wrong there.

Well, at least you have an extensive analyzer now.
So you'll know whether it's 'better' or not.
 
Simon Forsberg
Simon Forsberg
there are other ways of making fizzbuzz in Brainfuck, I chose a quite memory-tape-focused solution, to make it extensible for other woofs and barfs etc as well.
extensive? I don't know about that. I can analyze the source code instructions and the run-time instructions being performed, that's about it.

private void AnalyzeSymbol(SyntaxNodeAnalysisContext context)
{
    var csAttributeExpression = context.Node as Microsoft.CodeAnalysis.CSharp.Syntax.AttributeSyntax;
    var vbAttributeExpression = context.Node as Microsoft.CodeAnalysis.VisualBasic.Syntax.AttributeSyntax;

    // attribute must have arguments
    // if there are no parenthesis, the ArgumentList is null
    // if there are empty parenthesis, the ArgumentList is empty
    if (HasEmptyArgumentList(csAttributeExpression) && HasEmptyArgumentList(vbAttributeExpression))
That doesn't clearly show that one of the variables will always be null, so I have to use the && operator.
I guess I will just post a question on CR.

Excel-cells vs. Arrays/memory There is a difference of 8s (wow), but for 100K records; this gap is kept constant as far as it becomes 40s for 500K. This is undoubtedly relevant, but I understand that this is not a surprise to anyone: memory is the fastest alternative in any programming language (and dealing with Excel cells is almost like dealing with local files). On the other hand.. 100K records in Excel is not precisely a too common situation. — varocarbas 53 secs ago

@Hosch250 I don't understand at all why you can't do what I was recommending...
And your question doesn't clearly demark what is example and what is to be reviewed (and you should know better)
The vb.net tag on that question is probably a pretty terrible idea...
 
Hosch250
Hosch250
It is all to be reviewed, if you see something.
And there is vb.net in the unit test.
 
nhgrif

Yes and no.
 
Hosch250
Hosch250
Maybe I don't fully understand what you were recommending.
You say take one method, and pass it into two methods.
 
nhgrif
nhgrif
You are testing your C#'s ability to do stuff to VB.NET code you pass in.
But the VB.NET code isn't up for review
@Hosch250 No, I say write one method, and provide as many wrappers for it as you need to match the signatures you need to match.
 
Hosch250
Hosch250
OK.
So, wouldn't that end up duplicating all the code over again?
 
nhgrif
nhgrif
5:58 PM
No.
All of your code is in a single method. And you use if or switch or whatever means to handle the few divergent places, as you would normally do
 
Hosch250
Hosch250
Oh, OK.
 
nhgrif
nhgrif
All of your code is in the single method that the other "signature required methods" just wrap.
The methods that you must implement are 1-line calls to the main method that handles all of the logic.
