Consider these verses from Psalms 121:
"I will lift up my eyes to the mountains;
From where shall my help come?
My help comes from the L-rd,
Who made heaven and earth.
He will not allow your foot to slip;
He who keeps you will not slumber.
Behold, He who keeps Israel
Will neither slumber nor sleep."
G-d is the original server. He's 100% ready.
I turn to G-d and the Bible for inspiration
and understanding when it comes to providing
quality services. I also ask around here for
ideas. G-d has people all over the world.
Maybe we can agree that C++ is an excellent language
for writing services.

This is another answer to when Leigh asked me about
the possibility of me being hit by a bus. I replied
with the story about Elijah and Elisha, but here we
have supernatural protection so my foot doesn't slip.
And remember how Elijah was treated. He wasn't hit
by a bus, but was whisked away in a flaming chariot.

Are you really claiming that people should trust your code because it is
"inspired by God", and we can trust your company because you have
supernatural powers and will not die, but be "whisked away", and
presumably continue to provide customer service and support from heaven?
I don't really care what you believe in or not - faith is a personal
matter (except when it affects how you treat other people, of course).
If your faith inspires you to work hard and have confidence in the job
you do, then that's great. But the sort of twaddle you posted here has
no place in a business or profession. A piece of software has no faith,
and a company has no religion - you really have to learn to separate
these from yourself. If you can't do that, switch professions - you'll
make far more money as a TV evangelist.

Making all your source code available to others is good for trust, of

So you - on the basis of your beliefs in the OT - you are confident of
training a replacement before getting "whisked away" ?
If you are a one-man company, that's fair enough - as long as you are
clear about this to customers, and have appropriate measures in place
(available documentation, source code, license details, etc.) so that
they know how they can continue with their own work if you get hit by a
bus. But when you tell customers that they don't need to worry because
you've got God on your side, and you are the next Elijah, then any sane
customer will laugh at you.

A company has no religion. It is not a person, it does not have
beliefs. Your problem is that you fail to understand what a company
/is/, and mix it up with yourself.
A company has a /profile/, and that profile can have ethical or moral
standards (as long as they are legal and non-discriminatory) - but that
is not the same as claiming it has a religion.
> Would you agree that the US
> has Judeo/Christian roots?
A lot of the /people/ who formed the modern USA have Christian roots -
though many do not. The "founding fathers" attempted to make a country
where people could be free to follow whatever religion they wanted,
which was a noble aim and certainly /not/ a Christian idea. If
anything, their inspiration was the Roman Empire with its tradition of
tolerance for many peoples and religions.

It is well-known that the pilgrim fathers left England because of
"religious persecution" - what is less well-known is that it was the
sect left England because /they/ were not allowed to persecute others.
There was far too much religious freedom (i.e., several different
variants of Christianity were allowed) in England for their tastes, and
they wanted to go somewhere where everyone could be forced to follow
/their/ ideas.

It would be nice to have some documentation discussions
here. I acknowledge there's room for improvement on
the documentation and welcome specific ideas on how to
improve it. I've been focusing a lot on the software,
and the docs need work.

Ample evidence of the quality is available in terms
of both the generated code and hand written code.
There's also this page
http://webEbenezer.net/comparison.html
.
I'm not the next Elijah. I'm learning from his example.
Habakkuk 2:4
"Behold the proud, his soul is not upright in him; but the
just shall live by his faith."
I can give some help to people to make a decision about
using the C++ Middleware Writer, but as with any other
decision there's some risk involved. For those who are
living by faith in G-d it might be an easier decision
to make than for those aren't.
It doesn't hurt that the company has been here since 1999.
Maybe some will admit that making it to 2014 in better
shape than ever is evidence that G-d has helped us.

In G-d we trust is the national motto of the United States.
We're upfront about our faith in G-d. We let other people
know the source of our strength.

You fail to acknowledge our rights are from G-d.
Remember our name is Ebenezer - that means "So far G-d
has helped us."
Would you expect anything but the best of work
(interesting, rewarding, etc.) for those who follow G-d?

Your understanding is incorrect. They left in order
to follow G-d according to their conscience. I had
to do the same thing when I started a company. I left
behind those companies with immoral policies. If I
were an employee of IBM, Microsoft, Apple, etc. today,
some of the money I helped them make would be going to
support immoral lifestyles. I said, "Thanks, but no
thanks" to that. If you want to lead a G-dly life, it
will cost you some in terms of income. Unfortunately
what is considered "good" by some is evil from G-d's
perspective.
"Woe to those who call evil good, and good evil;
Who substitute darkness for light and light for darkness;
Who substitute bitter for sweet and sweet for bitter!"
Isaiah 5:20
I see this as a King David against Goliath struggle.
G-d blessed David with the victory over the foul-mouthed
Goliath.

I'm sure that something like g++ takes quite a long time to compile.
However, that doesn't make it less useful.

Having just debugged a professional well respected open source library, I

Although a cluster of smaller machines with the same number of cores
would almost certatinly have been a fair bit cheaper. Assuming we're
talking something like PCs where the prices of the low end systems are
substantially less per-MIPS than the big SMPs.
Still, there's no reason not use use all 192 cores for a build if you
have enough RAM and I/O, assuming you have the box already. But if
your application is big builds, a cluster is almost certainly going to
be considerably cheaper since (big) builds are mostly EP.

Date: Thurs, Jan 23 2014 9:39 am
From: "Rick C. Hodgin"
Is there a way to link object files between Visual C++ and GCC?
I have some data that I need to encode like this:
char* list[] = {
"one",
"two",
"three",
};
Unfortunately, by default, the list[0], list[1], and list[2] pointers point
to data that's in read-only memory. Any attempt to do something like
memcpy(list[0], "eno", 3) fails with "Access Violation" on Windows.
So, I discovered this syntax in GCC which creates the elements in read-write
memory, allowing memcpy(list[0], "eno", 3) to work properly:
char* list[] = {
(char []) { "one" },
(char []) { "two" },
(char []) { "three" },
};
I need the data pointed to by those list elements to be read-write in my
application. I can use this compound literal syntax in GCC to create
them in read-write memory, and it works in GCC. However, Visual C++
does not support this compound literal syntax and generates about 5
errors per line when I attempt it. :-)
I was wondering if there's a way to link in that one file, which will
contain nothing more than a list like this sample, but with about 100
separate elements in it representing a source code file I need to
modify somewhat at use (replacing placeholders like "[9999]" with the
actual runtime observed values, such as "[ 1]" and so on), to my
Visual C++ generated code in Visual Studio 2008?
I'm looking for something like this:
gcc -c my_list.c
cl /c my_prog.cpp
link my_list.o my_prog.obj my_prog.exe
Thank you in advance.

Should work, if you get the name mangling compatible. Since both
compilers use COFF format. But you're barking up the wrong tree: it
doesn't make sense to do this.
First of all you don't need the data to be read/write.
Secondly, if you did need the data to be read/write (which you don't)
it's trivial to specify that:
char item_0[] = "one";
and so on, as long item_0 is static.

Why not just use implementation-specific feature in VC++ to place your
data in the read-write memory and go for const-casting it before trying
to change? That's easier than linking GCC obj files with VC++ ones.
You also could simply declare your 'list' as an array of arrays instead
of the array of pointers. That would just as well allow you to edit
those elements:
char list[][10] = { "one", "two", "three" };
It's been a while I used straight chars, though, take it with a grain of
salt. Alternatively, use 'std::string':
std::string list[] = { "one", "two", "three" };
...
list[0]= "eno";
and forget about memcpy...

ICC will probably do it, it implements most GCC extensions.

gcc hasn't used COFF format for over a decade or more. ELF has been
the standard on unix and unix-like operating systems since 1990.
You are correct, however, in that it doesn't make any sense to do this.

My Bad - missed the windows references. Not surprising that they're
25 years out of date :-)

I was surprised to find that this code:
struct A { A(); ~A(); };
void bar();
void foo(bool f)
{
if (0)
{
LAB: ;
}
else
{
A a;
if (f) goto LAB;
bar();
}
}
will compile without warnings using GCC 4.7.3, even with -Wall and -Wextra .
The point, in case you were wondering, would be a macro-based "named block" pseudo-construct, where the block could be exited from any depth of block nesting, for example:
#define BLOCK(NAME) if (0) { NAME: ; } else
#define EXITBLOCK(NAME) goto NAME;
struct A { A(); ~A(); };
void bar();
void foo(bool f)
{
BLOCK(XYZ)
{
A a;
if (f) EXITBLOCK(XYZ)
bar();
}
}

And it actually skips the 'else' part when jumping into the 'if'
section, yes? And how well do optimizers handle it?
