To Register ( in German ): http://open-news-network.org/register
Once registered, use:  News.MB-Net.NET:119

When you post, it puts your IP address in the header.
It drops all posts from anonymous remailers, and such.

Please use HTML now exclusively.

You know, I have set up my newsreader to drop HTML posts completely as those 
come from completely clueless cretins not worth reading

That way it is a win-win situation: You can post your shite, and I will not 
see any of it.

I don't see HTML, either.  In any case, Relf is, of course, plonked.

2 weeks ago, you ( DFS ) showed me your "readable and maintainable" code:

  int isleapyear(int yr) {
   if(((yr%4==0) && (yr%100!=0)) || (yr%400==0))
    {return 0;}
   return -1; 
  }    //  oackac$fve$1@dont-email.me

Then I showed you my "kooky and oddly formatted" version of it:

  #define  isLeapYear(y) ( !( y%400 ) || y%100 && !( y%4 ) )

No _serious programming language lacks "evil" macros ! !

Shannon Entropy ( poorly ) estimates:
  the minimum number of bits needed to _encode data.

But I don't want to _encode/_decode anything; even if I did, 
Shannon Entropy can't predict the algorithm I'd use.

In thermodynamics "entropy" is how uniform the heat energy is;
i.e. how _spent it is, so it can't produce "Work" ( force*distance ).
In cosmology, we call this "heat death", the end of all "life".

What does "spent energy" have to do with compression ? ! nothing.

And you immediately show the danger of using macros. Just consider what
happens if you call it eg. like isLeapYear(a+b).

Even when you fix the macro, there's still the problem of calling it
like isLeapYear(someReallyExpensiveFunctionThatTakesAMinuteToReturn()).

Thanks for dreaming up scary scenarios however, 
like guns and knives, macros are useful too, not just dangerous.
No _serious programming language lacks "evil" macros.

Here's some more "scary" macros for you...

MicroSoft's WinMerge uses this this algorithm:
" Dynamic Programming | Set 4 (Longest Common Subsequence) "
  http://www.geeksforgeeks.org/dynamic-programming-set-4-longest-common-subsequence/

My code, below, produces the same results as WinMerge:

  //  ScreenShot:  http://Jeff-Relf.Me/Diff.PNG
  //  Help/Settings:  http://Jeff-Relf.Me/X.HTM

  //  _FileCmp(), below, records thousands of matching lines ( text ),
  //  LeftOlder vs RightNewer, using the "LongestCommonSequence"
  //  ( shortest diffs ) algorithm.
  //  
  //  BB is a pointer to the start of 
  //  a dynamic array of ( contiguous ) pointers ( lines );
  //  PP points to the end of the array.
  //  
  //   BB and  PP are from the LeftOlder file.
  //  _BB and _PP are from the RightNewer file.

  _FileCmp( LnA BB, LnA _BB, LnA PP, LnA _PP, LnT &Ln ) {

Dreaming up scary scenarios... Something like isLeapYear(a+b) is not
a stretch in any way. It's something that anybody would write. And your
macro would give the wrong answer.

And it is easily fixed by coding the macro correctly:

#define isLeapYear(y) ( !( (y)%400 ) || (y)%100 && !( (y)%4 ) )

You can code incorrectly in *any* language.

(too fast on the send button)

That still doesn't solve the problem of isLeapYear(j++).  But it doesn't
make macros any more or less evil than other statements.

Jerry Stuckle, Juha Nieminen, Mr. DFS... this would be be better:

  inline int isLeapYear( int y ) { return !( y%400 ) || y%100 && !( y%4 );  }

You know it's inlined when you can't set a break point on it.

Previously ( Jeff-Relf.Me@Mar.29--1.34P.Seattle.2017 ), I asked DFS:  <<

  Why reinvent the "mktime()" wheel, doesn't Python have it ?

    i64 aDate ;  tm DayRec = {};
    DayRec.tm_mon = Month ;  // 0..11
    DayRec.tm_mday = DayOfTheMonth ; // 1..31
    DayRec.tm_year = Year - 1900, aDate = mktime( &DayRec );
  
  You can add 200 days to DayRec.tm_mday, 
  and call mktime( &DayRec ) to normalize .tm_mday to 1..31, 
  adjusting .tm_mon and .tm_year accordingly.  >>


He didn't answer.

Why would I remove userfriendlyness and usefullness from linux to dumb it

People tend to forget about the struggles that they have with Windows.
Finding and installing all the software needed to make it useful,
defending against malware...

Doing all of that isn't very difficult; it's doing everything necessary
to get _rid_ of the malware which made its way onto your system despite
all of your best efforts that is difficult.
