From your earlier answers, it seems that when you went to your church and
asked people questions, the feedback you got was that you had to know when
to turn if off, when to shut it down.

The feedback I got was that people were scared or unwilling to
do what I am doing because they would lose friends.
 
Standing up for God necessarily means isolation and shunning and
mocking from those who are unsaved. And applying for real those
things taught in the Bible by Jesus and the apostles necessarily
means isolation and shunning and mocking by the lukewarm church.
 
Look up to God, Daniel ... and then walk as His very nature commands.

Sorry, I come from a tradition where good works matter, and while the belief
in supernatural beings has faded away, the idea of good works remains. It
seems to me that in your tradition, should the belief in supernatural beings
fade away, there would be nothing left.
 
You, too, live in the modern world, and I'm sure you understand why some
things are taught in Sunday school (or Friday school) and not in the regular
school curriculum. I'm sure you understand why your pastor does not consider
you qualified to teach on religious matters. I'm sure you realize that your
central argument, that people must perform some cognitive shift required by
some divine figure (you choose the Christian Jesus but there's no reason why
it could not be any of the other traditional divine figures), I'm sure you
realize that that would be unconvincing to a modern audience.
 
But I'm also fairly sure that you would be unable to stop spamming usenet
even if you wanted to, the obsession being that strong. It's as if you've
been exposed to a severe demonic molestation, but in the modern world, we
would call that a mental health problem, and react to it sympathetically, at
least most of us, some virulent posters here excepted :-)

msg-id = [CFWS] "<" id-left "@" id-right ">" [CFWS]
is defined in RFC 5322 which specifies an Internet
standards track protocol. On the Internet one cannot
get more standard than this.

You can read my articles directly from your server:
 
I assume your news server has the host name "news".
So, you start by
 
$ telnet news 119
 
Now you issue the article command followed by the MID, e.g.,
 
$ article <news-mid-20180114131816@ram.dialup.fu-berlin.de>
 
. If you should not have the MID,
 
$ group comp.lang.c++
 
211 100 1000 1100 comp.lang.c++
 
Now you see that there are articles from 1000 to 1100.
You want to see the head of the last article,
 
$ head 1100
 
Path: ...
 
$ body 1100
 
...
 
Many servers also support,
 
xover 1090-1100
 
finally,
 
quit
 
. As a small exercise, you can use these commands to
write your own newsreader in C++. Under Windows,
 
...
 
#include <windows.h>
#include <winsock.h>
 
...
 
SOCKET sock;
const int BUF_LEN=10000;
char File_Buf[ BUF_LEN ];
struct sockaddr_in address;
struct hostent * host;
test();
if(( sock = socket( AF_INET, SOCK_STREAM, 0 ))== INVALID_SOCKET )wserr();
address.sin_family = AF_INET; address.sin_port = htons( 119 );
::std::cout << "Connecting to host\n";
if(!( host = gethostbyname( "news" )))wserr();
address.sin_addr.s_addr=*(( unsigned long * )host->h_addr);
if( connect( sock,( struct sockaddr * )&address, sizeof( address )))wserr();
strcpy( File_Buf, "article <news-mid-20180114131816@ram.dialup.fu-berlin.de>\r\n" );
send( sock, File_Buf, strlen(File_Buf),0 );
recv( sock, File_Buf, BUF_LEN, 0 ); recv( sock, File_Buf,BUF_LEN, 0 );
::std::cout << File_Buf << '\n';
 
...
 
and so one, you get the idea.

Possibly, sometimes, something like
 
authinfo <username> <password>
 
is needed as a first command.

James opened a /new/ thread, because James' post
 
<aac2ba82-c585-dba0-a49c-28e737417461@verizon.net>
 
had an empty "References" header. His post just happened
to have the same "Subject" header as an older thread.

I can understand Geoff's disappointment because all of us
who have posted into this new thread should have chosen a
"Subject" header that describes the subject more appropriately.
 
I'm sorry about having posted with the wrong "Subject"
header myself.

When someone is learning Italian, he is supposed to learn
several irregular verb forms by heart. One single verb has
dozens of forms, and there are dozens of irregular verbs.
Not to mention literally thousands of nouns he has to learn.
 
A programmer should have mental capabilities way beyond
those of mere Italian learners. How can it be possible
that a programmer can't memorize 20 levels of precedence,
and shall not even be bothered to look them up? Even
ordinary doctors learn hundreds and hundreds of medical
terms.
 
Disclaimer: I don't know all precedence levels by heart,
I look them up if need be. This is what I can
write from my memory, but I'm just guessing, I'm not sure:
 
(x)
 
x[...]
x....
x->...
x(...)
x++
x++
 
--x
++x
-x
+x
!x
~x
 
x*y
x/y
 
x+y
x-x
 
x<<y
x>>y
 
x&y
 
x|y
x^y ???
 
x&&y
x||y
 
x?y:z (does not exactly fit)
 
x = y
x += y and so on
 
x,y
 
I'm sure I have made some mistakes and omissions above.
As I said, I look up the precedence when I need to know it.
ram@zedat.fu-berlin.de (Stefan Ram): Jan 14 09:54PM

Ok, now correcting, using notes:
 
>x....
>x->...
>x(...)
 
Here, a new level should have started by writing
an empty line.
 
>x++
>x++
 
Was intended to read "x--".
 
>+x
>!x
>~x
 
forgot: &x, *x, sizeof x
 
forgot: (cast)x
 
>x*y
>x/y
 
forgot: x%y
 
>x-x
 
>x<<y
>x>>y
 
Oops, a major omission: Totally forgot
x<y, x>y, x<=y and x>=y here.
 
x==y x!=y
 
>x&y
 
>x|y
>x^y ???
 
^ is higher than |, I thought about that
possibility, but was not sure.

Whatever /those/ are ...

I'd place the implementation of askSample() here, in an anonymous
namespace. People probably think differently about it, but I really
dislike forward declarations; I'm much happier with having functions
(and other things) appear just when they're needed -- even though that
means main() as to come last.

Unrelated to C++, but that kind of prompting is almost always the
wrong user interface for a real program.

You use the same warning options as me, so I obviously approve ;-)
 
IMHO, since you seem to be on Unix, you should write a Makefile. This
would do for your case, I think:
 
CXXFLAGS=-std=c++17 -pedantic -Wall -Wextra
a.out: 232.o
$(CXX) $(CXXFLAGS) -o $@ $<

I think the same as you - I prefer to order my code as bottom-up. And
it should definitely be in an anonymous namespace or "static" (static is
perhaps a bit old-fashioned).

Here is a standard link that would be clickable if our tools still worked:
 
<url: news://getc-count-20180112172146@ram.dialup.fu-berlin.de>
 
I tried it with both Thunderbird and Sylpheed and they don't do what a
news client should do. But it's still better than a non-standard format
that gets erroneously interpreted as a mail address.
 
With a bit more work one can find a GMail archive URL, e.g. as discussed
here,
 
<url: https://productforums.google.com/forum/#!topic/Apps/UCY9_ek0h3o>
 
Essentially, in Google Groups search for "messageid: MY_MESSAGE_ID"
 
For the above message that kind of search yielded exactly 0 hits.
 
However, a ditto search for ...
 
 
> that you then replied to in your message
 
> <p3dkbh$ek8$1@dont-email.me>
 
yielded
 
<url:
https://groups.google.com/forum/#!msg/comp.lang.c++/MWSZ4KlLu7I/sb8xwHFjAwAJ>
 
which headers show that the message id given earlier was correct.
 
It seems that Google Groups don't archive your posts in comp.lang.c++.
 
Perhaps you're posting with "don't archive this please" header?
 
Checking...
 
Yes, you have imposed your own silly scheme that nobody knows about:

Let me quote what you snipped:
 
>> services to mirror the article via the web (HTTP). But Stefan Ram
>> hereby allows to keep this article within a Usenet archive server
>> with only NNTP access without any time limitation.
 
And no, a message id is not an URL.
 
Still, maybe the URL I tried was incorrect, e.g. the "//", but much
better than what you posted that modern clients interpret as an e-mail
address.
 
Cheers & hth.,

This is possibly a Thunderbird bug. I have seen this happening on rare
occasions - I think mainly in connection with network problems. My
theory on what happens is that Thunderbird has collected the start of
the post (subject, reference, poster) but has not bothered to collect
the body of the post until you start to read it. However, if there is a
problem in the network, server, etc., when you try to read it, it is
possible for Thunderbird to mark the post as downloaded and read, even
though it did not actually get it.

This isn't the first time it's happened to me, and your guess seems
consistent with the symptoms I've seen. It is the first time that it's
affected a message that seems to have been a response to one of my
messages, where that response was unavailable on Google Groups (due to
Stefan's No-Archive headers).

I just looked. There are 17 levels of operator precedence.
 
Please consider that future readers of your code may not have memorised

The problem with Boost is that their header files are linked like so:
 
# include <boost/config/detail/select_compiler_config.hpp>
 
Now in VS this is not going to compile because it requires linking like
this:
 
# include "boost/config/detail/select_compiler_config.hpp"
 
Now if it is one or two files you can change quickly but Boost has
nested header files (about 63,000) so it is almost impossible to change
all of them.
 
Both VS and Builder C++ (Embarcadero) complains about this type of
linking. Why they decided to do this is something I don't know. Perhaps
there must be another way to compile these files in your project.
