Toon Krijthe posted an interesting question to SO.
Though 5 years old, I think it stilll is very valid one:
At my work, we have decided to stay with the ANSI characters for identifiers. Is there anybody out there using unicode identifiers and what are the experiences?
For all projects I work on (in various Languages like English, German, Dutch or other), I stick to ASCII characters (not even ANSI) for:
I also try to abstract the non-ASCII strings into places where I am sure that the encoding is preserved (for text files, I prefer UTF-8), or where these characters are properly escaped.
What is your take on this?

Igor Ostrovsky wrote a few very nice MSDN magazine articles. Not all of them have ended up in the list at MSDN magazine, so here is a more complete list:
Though the articles show the majority of sample code in C#, the actual topics are of great interest to any developer writing .NET code or interfacing to it.
Some keywords in his articles: Read the rest of this entry »

2 more issues got on-line both close to a 100 pages each:
So the only issues missing are #28, #30 and #31.

I was involved in a big project migrating a complex stack from Windows XP to Windows 7 x86, and got scared this !@#$ out of me.
The stack communicated to WebSphere MQ on AS/400 from Windows, and on the Windows side of things consisted of a UI developed in in Cool:Gen, a C interface to a Delphi DLL, which takes care of the communication to WebSphere MQ.
Digression:
This all was histerically grown. In the beginning (early to mid 90s last century) it was a big Borland Pascal/Turbo Pascal application – running on DOS, Windows 3.1x, Windows 95 and OS/2 2.x/3.0 – that talked over a propriatary layer over SNA to AS/400.
The vendor of that layer didn’t respond to a request for Windows NT 4.x compatibility, and meanwhile some client applications were about to be developed in Delphi.
So in 1997/1998 – together with a great AS/400 software developer – I wrote a SNA based APPC/CPI-C communication layer in Delphi 3 that could be accessed from both Turbo Pascal (using a file based interface) and Delphi (using an object interface).
The DOS interface was an executable around the Delphi interface, which was a set of classes.
Delphi part
The Delphi part of the DOS interface was centered around FindFirstChangeNotification/CreateProcess combined with MsgWaitForMultipleObjects/WaitForSingleObject to make the waiting as efficient as possible.
DOS part
DOS part
The DOS part of the Delphi interface was centered around this piece to make waiting efficient:
asm
int $28
mov ax, $1000
int $15 { DESQview/TopView give up time slice }
mov ax, $1680
int $2F
end;
Thanks to the RBIL: Ralf Brown’s Interrupt List (there are now multiple HTML versions of it), it makes use of these tricks so DOS applications can efficiently wait : Read the rest of this entry »

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.

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.

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 »
