If you want proof of G-d's existence, consider the C++
Middleware Writer. As G-d helped David to defeat Goliath,
He helps us to build the best software in existence.

Proof by repeated assertion does not work when given by Christians - it
does not work when given by Mr Flibble either.
 
There /is/ archaeological evidence for the existence of both King David
and Jesus. Obviously there is no evidence for anything divine or
supernatural being involved, but people who actually /know/ something
about history and archaeology are mostly agreed that these people were
real, and at least some of the events mentioned in the Bible are likely
to have a basis in fact.
 
The evidence for King David is not strong - it is certainly not "proof",
and for most of what is written in the OT, there are no other sources.
But there is enough to say it is likely that the character in the OT is
not entirely fictional even though many of the details and the deeds
attributed to him may be fictional, mistaken, or wrongly attributed.
 
<https://en.wikipedia.org/wiki/David#Archaeology>
 
For most of the "historical" events described in the Bible, OT and NT,
there is very little evidence for or against the Biblical story. But
"very little" is significantly different from "absolutely none".
 
 
Regarding the historical Jesus, there is a little more information:
 
<https://en.wikipedia.org/wiki/Historical_Jesus>
 
(The Wikipedia articles are, of course, not an authority of some kind -
but they give a good starting point for further research.)
 
Most Biblical historians agree that Jesus existed, with a few events in
his life having at least some evidence - but there is good reason to
suspect that he was not particularly important, but merely one of the
great many preachers, teachers, "holy people", and "prophets" that were
common in that time and area.

That is not "proof", it is faith or belief. If you are happy to believe
in God, that's fine - but please do not call it "proof".

The story of the "pilgrim fathers" on the Mayflower escaping religious
persecution in England, and forming America based on freedom and
religious liberty, is part of the USA's own creation myth written
shortly after American independence. In fact, the pilgrim fathers were
running /from/ religious freedom - back home in England, they had been
doing their best to persecute other Christian groups and force their
particular brand onto everyone else. They set out for America to find a
place where they could control and enforce their own version of
Christianity on everyone else.
 
(You can either accept that argument, or deny it, or do some research on
the subject - I don't have any references at hand, and don't have the
time to find them myself, so I will not blame anyone for disagreeing
with me here. But perhaps it will make you think a little about what
you think you know.)

There is absolutely no evidence whatsoever that King David or Jesus
Christ existed, none.

Some guy that the fictional Jesus Christ may have been partially based
on and the fictional Jesus Christ ARE NOT THE SAME INDIVIDUAL. Jesus
Christ never existed.

He just needs to tweak his meds. He'll be fine.

Just reject everything with bald assertion that purely negates opponent's
point.

Just restate your original bald assertion again. Write nothing else.
 
Turing test: false. Consciousness level of author detected: 0, because
algorithm matches exactly with what I predicted.

The problem is that Mr Flibble is outside his field, and isn't familiar with the scholarly work, but still feels it necessary to make utterances. Had he read a bit about the minimalist position on the authenticity of the texts, he would have been able to engage with David in an interesting way, but he obviously hasn't.
 
In much the same way, and just to bring this back on topic, it's rarely interesting to read something critical about C++ from somebody who doesn't know anything about C++.

I am processing a file that's "named" .csv, but which isn't. It's a
file with values that are separated by tab characters...but there's a
lot of data that isn't data at all. For example, every character is
followed by a '\0' character, and there are non-ASCII characters at the
"front" of the data stream record.
I want to process this file as though it's a comma-separated file,
and I'm cleaning it up with the following code (which works - the data
line goes from 1289 characters to 389 characters):
 
size_t ttt = 0;
while(ttt < str.length()) // clean up line; replace Tabs w/commas
{
if((str.at(ttt) > 127) || (str.at(ttt) < 1)) str.erase(ttt, 1);
else
{
if(str.at(ttt) == '\t') str.at(ttt++) = ',';
else ttt++;
}
} // while
 
There may be other, better ways, to do this. I assume that using an
iterator is one, but I don't know quite how to do so (when to advance
the iterator, etc.). Are there other, better, ways? If so, can someone
show me how? TIA

If (almost) every second byte is zero and there is a BOM marker in the
beginning then this most probably means this file is in Unicode UCS-2 or
UTF-16 encoding. On Windows you should use std::wstream and std::wstring
for processing it. Your current approach is corrupting any non-ASCII
characters in the file, apart of other problems.
 
If you have your file read into a std::wstring, you can translate tabs to
commas by a single line:
 
std::replace(str.begin(), str.end(), L'\t', L',');

The file might be encoded in UTF-16 or UCS-2 with a BOM or
some such.

The front-door solution is to get the documentation, where
it is being specified which grammar is used for the file.
 
If it is a text file, the encoding should be given by the
documentation of the file. In this case, one can write a
function to get the next Unicode code point from the file,
and then one still needs to know the grammar to properly
parse the file.
 
»CSV« is not a specification, because, as you have observed,
that term is too vague. There is a whole family of languages
named »CSV«.
 
::std::string::at for me somehow a kind of abstraction for
parsing that feels unusual to me. When I am scanning or
parsing a text, I am thinking in terms of
»get_next_code_point«, »peek_next_code_point«,
»get_next_token« and so.
 
I can only write a parser, once I have a grammar. I do
not have a grammar for your file. So I can't write a
parser for it.
 
For example, here is a parser for a simple type of
arithmetic expressions:
 
#include <iostream>
#include <ostream>
#include <sstream>
 
template< typename scanner >struct parser
{ scanner s; parser( char const * s ): s{ s } {}
int numeral(){ return s.get() - '0'; }
int prefix(){ int sign = 1;
while( '-' == s.peek() ){ s.get(); sign *= -1; } return sign * numeral(); }
int start(){ int result = prefix();
while( '-' == s.get() )result -= prefix(); return result; }};
 
int main()
{ using p = ::parser< ::std::stringstream >;
auto test = []( char const * s ){ ::std::cout << p{ s }.start() << '\n'; };
test( "4-2" ); test( "-4-2" ); test( "4--2" ); test( "-4--2" );
test( "-4---2" ); test( "--4--2" ); test( "4-2-1" ); test( "4-2--1" ); }

Hi!
 
One of our best C++ programmers Andrei Alexandrescu, recently decided to
leave his work and focus completely on the programming language D.
http://forum.dlang.org/thread/xsqrdgwnzehdmfmvcznn@forum.dlang.org
 
Today his book The D Programming Language is on sale at informit.com for
a bargain. http://www.informit.com/deals/
 
If you missed the sale you can still find it here.
http://www.informit.com/store/d-programming-language-9780132654463
 
It's good to have Alexandrescu back on programming language research
since he contributes a lot, not only to D but also C++.
 
Here's another book he has written that is a great start for anyone that
wants to become more handy with templates.
http://www.informit.com/store/modern-c-plus-plus-design-generic-programming-and-design-9780201704310
 
 
Best regards,
Daniel
 
PS. No I'm not paid to write this, it's just that Alexandrescu's books,
talks, and work in general have contributed a lot to the programming
community and to me personally. :)
