OT: Computer Programming

I prefer Nginx

en.wikipedia.org

What does Nginx do, and why do you like it over the above two?

Thanks,
SJG

Nginx handles static content better, which is most anything I program. Apache is better for dynamic content.

^^^^^ Thanks,

SJG

Those Apache projects have nothing to do with the traditional Apache web server. Sure they could be..involved...behind the scenes but. Nevermind.

FRMOS with great multithreaded, ULL cache targetting, avx512 optimized code makes things fast.

^^^^ Agreed, and thanks for the info. That was also my perception of the above software things.

^^^ based on what I see it looks wonderful. Still like to find some books and first hand accounts.

Not interested in it for general purpose, but for some small embedded applications, and maybe running with no operating system underneath.

They say it is like SmallTalk, fine. Or I see it as also like Oberon. But I also see it as the new Forth.

And of course I want to add complied C++ to its interpreter, not just write in its interpretive stuff. And highly object oriented is ideal.

So let me look some more at "Io".

What processors, what compilers?

Cross compilers?

Download and then use make to compile Io (its interpreter and runtime stuff)
iolanguage.org

Here is source code, on GitHub ( I think run by Google )
github.com

Linux Build Instructions
github.com

Everything for this must be GNU, and they want on Windows for you to build using Cygwin

cygwin.com

But can you cross compile? Mostly I want to use Io on ARM processors. But I will not want to compile it there, want to compile on a PC, probably using Linux.

GNU C complier ( GCC )

gcc.gnu.org

GCC 7.5 released [2019-11-14]

GCC 9.2 (changes)
Status: 2020-02-28 (regression fixes & docs only).
Serious regressions. All regressions.

Says these are the GNU GCC targets

gcc.gnu.org

so for example:

aarch64*--

gcc.gnu.org

Talk about some corrective for Cortex-A53

Special stuff about MS-DOS
DOS

Please have a look at the binaries page.

You cannot install GCC by itself on MSDOS; it will not compile under any MSDOS compiler except itself. You need to get the complete compilation package DJGPP, which includes binaries as well as sources, and includes all the necessary compilation tools and libraries.

All the GNU complier manuals

gcc.gnu.org

GNU Fortran Manual
gcc.gnu.org

Talks about Fortran 2003, 2008, and 2018 !!

So this is the manual for all of the GCC compilers ( G Compiler Collection )
gcc.gnu.org

for example, special options for the BlackFin processors, I guess on all GCC compliers:

Specifies the name of the target Blackfin processor. Currently, cpu can be one of ‘bf512’, ‘bf514’, ‘bf516’, ‘bf518’, ‘bf522’, ‘bf523’, ‘bf524’, ‘bf525’, ‘bf526’, ‘bf527’, ‘bf531’, ‘bf532’, ‘bf533’, ‘bf534’, ‘bf536’, ‘bf537’, ‘bf538’, ‘bf539’, ‘bf542’, ‘bf544’, ‘bf547’, ‘bf548’, ‘bf549’, ‘bf542m’, ‘bf544m’, ‘bf547m’, ‘bf548m’, ‘bf549m’, ‘bf561’, ‘bf592’.

Blackfin processors could be very useful, for some stuff:
en.wikipedia.org

Offical Blackfin, lots of part numbers, with datasheets
analog.com

Sometimes you have to accept single source solutions. But I would be concerned that this Blackfin unnecessarily could get you into a single source solution.

SJG

Here is IA 64. As I know this is Intel, and what it is, is in the later Pentiums when they added the full on 64 bit mode.

gcc.gnu.org

This is 68000 and Coldfire options
gcc.gnu.org

More about AArch64
gcc.gnu.org

Special options for AMD GCN, like for PC Gaming, great images
amd.com

gcc.gnu.org

Extensions to C language
gcc.gnu.org

Extensions to C++ language
gcc.gnu.org

talks about HSA language and D language, also Go language and G++.

From all of this I see that C/C++ is heavily used, as is Fortran. But Pascal does not exist. And Ada is really very secondary.

Compiling C++
gcc.gnu.org

C compiler options summary
gcc.gnu.org

I am getting the impression that cross compilation options are just built in. If you can get the compiler running on your machine, then you can compile for any of the vast array of supported processors.

This is 1 million times better than how it would be on commerical proprietary software development tools!

No I am not suggesting that this is easy. I know that it is not. But at least the people driving it are thinking the right way!

SJG

Now we talk about Floating Point
gcc.gnu.org

Some targets have 128 bit integers
gcc.gnu.org

Some support for Complex numbers.
gcc.gnu.org

That might be done in a manner which is not useful.

Says their is some float128 !! Not sure how this really plays out though.

__float128 is available on i386, x86_64, IA-64, and hppa HP-UX, as well as on PowerPC GNU/Linux targets that enable the vector scalar (VSX) instruction set. __float128 supports the 128-bit floating type. On i386, x86_64, PowerPC, and IA-64 other than HP-UX, __float128 is an alias for _Float128. On hppa and IA-64 HP-UX, __float128 is an alias for long double.
__float80 is available on the i386, x86_64, and IA-64 targets, and supports the 80-bit (XFmode) floating type. It is an alias for the type name _Float64x on these targets.
__ibm128 is available on PowerPC targets, and provides access to the IBM extended double format which is the current format used for long double. When long double transitions to __float128 on PowerPC in the future, __ibm128 will remain for use in conversions between the two types. 

Power PC does also involve IBM.

Look at this chip package:

Special ARM options

SJG

So let me try to look at the GCC linker:

gcc.gnu.org

talks about ASM relations
gcc.gnu.org

Still taking effort to make progress in learning about this.

Enumerator Attributes
gcc.gnu.org

gcc.gnu.org

^^^^ I don't think that is a good thing to do. Microsoft pushes this, came from them.

So try to get back to linking issues:
gcc.gnu.org

Looking for overlay capabilities in linker. Not seeing it.

Starting at the top again:
gcc.gnu.org

GNU origins and operating system
gnu.org

gcc.gnu.org

look at this, quad precision math library?
gcc.gnu.org

Quad precision, meaning 4 times 4 bytes, 16 bytes, 128 bits?

But this is in software. Still useful. About 33 decimal digits precision, plus the exponent.

Suggests that one way or another, there will be the needed hardware.

SJG

So let me try to look up their linker this way:

en.wikipedia.org

Well they talk about Dynamic Linking, but they fail to talk about the importance of this in these interpretive langauges, being able to expand them.

They don't even talk about doing overlay linking, except for one thing. IBM 360 has more data in the output file, so you can remove some stuff from a linked program, and then put other stuff in, without have to recreate all the object files.

This, ld, should be the GNU linker manual
sourceware.org

And then here, talked about with Linux

linux.die.net

There is stuff about dynamic linking. Maybe they let you tell the machine how to do Virtual Memory swaps. That would be good, but still cannot really see that for sure.

Not sure what this is:
linux.die.net

Unix is multi-user and it has Virtual Memory, so it is going to be more complex.

So if they overlay linkers are no more, I think you could still write C/C++ extensions to these interpretive langauges, and then have the extensions loaded when needed, and the I think dump them when no longer needed.

Some are looking more to C++ for Functional Programming.

Mostly this is due to the Standard Template Library. And in my view, this is the right way.

Now C++ is not interpretive. Some things really do need an interpretive language. But in my view the popularity of many of these interpretive languages is not based on solving real issues, it is based on specious reasons for making the choice.

Interested to know what you think.

Seven Concurrency Models in Seven Weeks
When Threads Unravel
by Paul Butcher

The Pragmatic Programmers ( This publisher and this series are always really good )

amazon.com

SJG

link your github

So I read the above and he gives examples and discussion based on using Clojure. I feel that this demonstrates my contention that these new functional programming languages are not really helpful but are more of a hindrance. What he shows works, but the reason that it works is that what you need for concurrency is already built into Clojure. Okay, but if it is not a class assignment and instead it is a real work application, you need tools, not toys. You are responsible for the entire application from top to bottom, and for the careful judgements used in making it.

You can write it all yourself, or you can use library modules to do all of these things. But that still gives you a great deal more ability to tailor the result to your actual need than you would get from using Clojure, Scala, Lisp, Scheme, Prolog, Erlang, or Elixir.

I read all the discussions and examples and I can relate it to things I was responsible for decades ago. The concepts involved are very important. But I still see most of these new languages as gimmicks.

And then you have books like:
amazon.com

Totally disingenuous. They say you can do this and this and this. But they forget to tell you that the reason this is so is simply that others have already written the code to do these things and this is what is inside of Clojure. For a real world application much more is expected of the people responsible for it.

And then there is the loss of control of how it works via the Java Virtual Machine. Can't do stuff that way, not acceptable. If things are to be farmed out to multiple CPU's, you need to decide when and how this will be happening.

Good to see you here SanchoRG.

Seven Concurrency Models in Seven Weeks
When Threads Unravel
by Paul Butcher

Yes, so he talks about threads and locks.

He talks about Functional Programming, but out of its original context of Artificial Intelligence, in the context of Concurrency. And the central thing seems to be immutable variables.

My view is that you can make things to do this in any Object Oriented language, if you wish to.

He talks about Clojure and a lot of the concepts which underly it.

He talks about Actors, which in my view is a phenomenal way to go. He explains that it does not depend on immutable state variables, just on keeping them private.

Now he does his examples in Elixir. But remember that Elixir runs on their BEAM operating system. While I respect the great things which have been done with Elixir, I still do not think it hte best available way.

The he talks about CSP, Communicating Sequential Processes, the language Go, and a new library for Clojure. Not really impressive to me.

Then he gets into Data Parallelism and GPU ( Graphics Processing Units )

Computer coding once had much better gender balance than it does today. What went wrong?

Did stripping pay more?

I agree with you. What people say is that it was the rise of the Internet. Because of this, computer programmers started to have greater social status and to get better pay. So what they say is that the women were chased out. People have written about this and have tried to do something to get back to better balance.

I have not read this but I want to. I know that it talks about a great deal of sexism in work places. I am not surprised that they are seeing this.

thriftbooks.com

SJG

Not taking sides on this, but I think Shevinsky wants to say that the men don't want to see the women as equals. Rather they want to hire them as strippers, literally.

Other accounts of men being interviewed for a position and being unwilling to talk with female interviewers, staying silent until they can present him with a male.

These guys do this even though the women are the hiring manager and the company founder.

Okay, but I listen to this and I listen to some of what Shevinsky says and I see these as only quasi-technical positions. They pertain more to consumer marketing and canned programming environments, and so the men don't want to be cast into that role, a role they see as more suitable for women.

But I also know that there are many men who don't know the difference and who could only function in that kind of a realm themselves.

This is why I want to read Shevinsky and a lot of other related things which are coming.

Shevinsky just made a video on the Google Campus where she was walking down their halways and through their doorways, and she was noting that they could have offered her a job if they wanted to, but they didn't. I found her position to be a bit much. But still I want to read and understand before I take a position.

Erlang and Elixir for Imperative Programmers, by Wolfgang Loder (2016)

My view is still that it is better to learn from and understand these langauges, but not to use them. Don't want to use their BONE virtual machine, can't write everything their way.

Instead put the time in and make a nice C++ class library, accessible through C/C++, R, Python, or Ruby. Use this for you Imperative Programming. And it is inside of the mechanics of your class library that your multiprocessing and hot swap capabilities reside.
