memories of the past: BitSavers.org just added a whole bunch CRAY documents

Posted by jpluimers on 2013/05/16

Nobody but very wealthy research institutions could afford CRAY machines.

They were the computing workhorse of their time. Now your smartphone is faster (:

BitSavers just added a bunch of CRAY documentation of the 1980s and early 1990s.

More Old Micro Cornucopia issues on BitSavers from 1987 and 1988

Posted by jpluimers on 2013/04/08

Last quarter, 11 issues of Micro Cornucopia appeared on BitSavers including the final May 1990 issue.

This month, another 7 issues appeared, most of which cover a form of Pascal in one or more of the articles and advertisements:

A fun thing to notice are the advertisements for Modula-2. Logitech Modula-2. Yes though the Logitech Wikipedia page does not mention it at all, Logitech didn’t only sell mice, keyboards and web-cams. They had more products. Being Swiss, they were big in Modula-2. And Bitsavers has a PDF of that too: Logitech_Modula-2_86_1.0_Feb84.pdf

The only issues still to be scanned are #28 till #32.

Found a table with Delphi Conditional defines over the Delphi versions/compiler platforms/bitness

Posted by jpluimers on 2013/02/20

Right now, documentation on Delphi Conditional Defines is on pages like Conditional compilation (Delphi) – RAD Studio XE2, but it is limited as it is for one specific version of Delphi only.

However, over the course of Delphi versions, compiler platforms and bitness, and not forget Free Pascal and Turbo Pascal/Borland Pascal, the matrix has become huge.

There is no complete documentation on that in one place. Right now include files like Defines.inc, the DSPack.inc, the JCL include directory the JVCL common include directory and the Jedi.inc documentation contain the collective knowledge about this.

Someone should condense that in a table and – more important – keep it up to date.

At least now there is a post collecting some of the links that contain the knowledge (:

Found one that contains these columns

  • Product & Version
  • VERxxx defines
  • __BORLANDC__ value
  • RTLVersion
  • CompilerVersion
  • Package Version

via Compiler/RTL version overview « Muetze1 wich is now available on the wayback machine: http://web.archive.org/web/20131229055045/http://www.muetze1.de/?page_id=547

New Micro Cornucopia issues on BitSavers (including the Final May 1990 issue)

Posted by jpluimers on 2013/01/26

Back in the days I started programming, Micro Cornucopia was a wonderful magazine, so I’m glad that BitSavers scanned a few more issues and put them online today, a week after some great PDF scans: Turbo Assembler/Debugger (1993/1994), Borland C++/Object Windows Library (1993):

They covered a lot of languages (x86 and 68k assembly, C, C++, Turbo Pascal and many more), and very interesting hardware designs.

New BitSavers.org PDF scans: Turbo Assembler/Debugger (1993/1994), Borland C++/Object Windows Library (1993)

Posted by jpluimers on 2013/01/17

The PDF Archive at bitsavers.org has recently put online these raster image PDF scans from Turbo Assembler/Debugger (1993/1994) and Borland C++/Object Windows Library (1993)

Remnants of the past, usefull for RAD Studio, Delphi and C++ Builder developers wanting to know a bit of history (: Read the rest of this entry »

Found back my WinImage license (still going strong: What is WinImage)

Posted by jpluimers on 2012/12/10

Every once in a while I need some disk imaging software. After all these years, WinImage is still my tool of choice.

This time, I needed it to create a Creating vSphere 5 ESXi embedded USB Stick.

Usually I only need it for a day or two, and most of the times I have reinstalled my system between uses. Not this time, so I needed to enter the license, which I knew I had, but had to search for it.

Luckily, I have installed the Lookout search tool for Outlook (which – even though you cannot officially get it any more – is so much better than the integrated search).

It found back the below message, from 1997.

1997! And the license is indeed perpetual: it still works on the most current WinImage build (which now supports x64 as well as x86, a lot more disk image formats and disk types, etc).

The WinImage site references some very old tools back from the days when you had BBS, Fidonet, ARPANET, Simtel, and Compuserve (the latter both hosted on PDP-10 machines, 1970s based technologies still ruled many of the computing world).

But I digress.

Back then, the only disk image supported were floppy disks, and most tools were DOS based. Like the FDFormat tool from Christoph H. Hochstätter which allowed you to add 300 kilobyte of extra space on 3.5 inch 1.44 megabyte floppy disk.

You can still see that in the WinImage binaries: Bootsector from C.H. Hochstatter

The email:

From: Gilles Vollant [mailto:——@winimage.com]
Sent: 07 December 1997 13:02
To: ‘——@xs4all.nl’
Subject: WinImage registration notification

Thank you a lot for registering WinImage 4.00 Professional

Your code of registration is:
J——s
—————

Note there is now french, english, italian, portugese, spanish and german version of WinImage.
I send you a floppy with WinImage 4.00 and my freeware Extract. I hope you’ll be happy with WinImage !

Don ‘t hesitate to upload it on BBS and give to your friend !

Only two question : Where did you find WinImage and do you Windows 3.1, Win
95 or WinNT version, or both ? (you can answer in french or english)

For getting more information, you can connect on my web site at :
http://www.winimage.com/winimage.htm
and at http://www.winimage.com for information and downloading other tools (including related to WinImage)

Regards,

Gilles Vollant

remanence of the PC computing past: Intel MCS-86 Assembly Language Reference Guide

Posted by jpluimers on 2012/09/24

Remanence of the PC computing past: Intel MCS-86 Assembly Language Reference Guide on bitsavers.org in http://bitsavers.org/pdf/intel/8086.

Intel MCS-86 is/was the 16-bit range of x86 processors.

I used it in BASM (not only in Delphi 1 and up, it started in Turbo Pascal 6), and before that in MASM, NASM, and TASM.

:-) and :-( turned 30, thanks Scott Fahlman!

Posted by jpluimers on 2012/09/19

Today they :-) and :-( turned 30. Happy birthday!

The first use was attributed to Scott Fahlman.

Over the last few years, I switched to reverse smileys as too much software tries to graphicalize the regular ones.

Great session on how to prevent SQL Injection Myths and Fallacies

Posted by jpluimers on 2012/08/15

A few weeks ago, Bill Karwin did a must watch webinar on the prevention SQL Injection titled  “SQL Injection Myths and Fallacies“.

Bill Karwin (twitter, new blog, old blog, Amazon) is famous for much work in the SQL database community, including InterBase/Firebird, mySQL, Oracle and many more.

He also:

Anyway, his webinar is awesome. Be sure to get the slides, watch the replay, and read the questions follow up.

Watching it you’ll get a better understanding of defending against SQL injection.

A few very valuable points he made: Read the rest of this entry »

Hollerith and why we have digraphs in Pascal and trigraphs in C/C++ (nostalgia, Apple ][ plus)

Posted by jpluimers on 2012/07/04

Apple ][ plus keyboardSome nostalgia (:

In the mid 80s, when programming in UCSD Pascal and Turbo Pascal, I learned that Pascal has (. and .) digraphs that translate into [ and ], similar to the (* and *) digraphs that translate to { and }.

In fact I thought the English word was bigraph (as bi- is a prefix for twice, just like tri- is a prefix for thirce).
The digraphs are lexical alternatives (Pascal ISO  standard 7185:1990 paragraph 6.1.9 or Extended Pascal ISO standard 10260:1990 paragraph 6.1.11). There is even one more: the @ at-sign is a lexical alternative for the ^ caret.

Back then (I was in my teens, there was no internet yet and school library had nothing on programming) I thought these were because keyboards like those of the Apple ][ plus couldn’t emit [ and ], but I was wrong: it was in fact the Hollerith Card Code that could not represent these characters.

That limitation was because of the first Pascal implementation was done on a CDC 6000 series that used punched card readers/writers.  You could not punch arbitrary numbers of holes on each row (lace cards lacked structural strength) limiting the character codes you can represent.

They still work in the Delphi compiler for arrays and for comments (I just learned that various Pascal implementations use different rules of mixing digraph and normal comments (some even allow nesting)).

While I taught myself C and C++ just as I taught myself Pascal, somehow I never learned that they use lexical alternatives too. It was only recently that they do, both as trigraphs and as of C99 also as digraphs and that there is even a trigraph tool as part of the C++ personality of RAD Studio 2007.
