2 More Old Micro Cornucopia issues on BitSavers from 1986 « The Wiert Corner – irregular stream of stuff
Posted by jpluimers on 2015/06/18
Almost two years ago, I wrote “the only issues missing are #28, #30 and #31.”. As of mid May any more:
All of them are from the 5th anniversary year.

Now that XE8 is out, some Turbo Pascal history
Posted by jpluimers on 2015/04/14
A few people asked, so below is a picture of just a piece of my books closet.
From left to right:
- Object Professional 1.0 manuals volume 1-3
- BTree Filer 5.0 manual
- Turbo Professional manual (from 1985!)
- Borland Paradox Engine 3.0 manuals
- Crystal Reports Developers Edition
- Borland Open Architecture Handbook for Pascal
- Turbo Pascal 5.5 OOP Guide
- Turbo Pascal 5.5 Reference Guide
- Turbo Pascal 5.5 User’s Guide
- Turbo Pascal Quick Reference
- Programming with Turbo Vision
This is only the front-left portion of one shelve. Most shelves are two deep and about 4 times as wide as what you see here (:
I have floppies somewhere in my archive too. Need to dig them up some day.

Blast from the Past: `TThread` got introduced in Delphi 2
Posted by jpluimers on 2015/01/03
Thanks Nick Hodges for asking, and Uwe Raabe for answering:
Yep! Delphi 2 had TThread while Delphi 1 did not.
It resulted in an interesting thread including topics like cooperative multi-tasking and named pipes under DOS by using Turbo Pascal.
Boy, I remember the \pipe\ days and releasing a time slice by calling INT $28, $15 and $2F combinations like this:
This file contains hidden or bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.
Learn more about bidirectional Unicode characters
| asm | |
| int $28 | |
| mov ax, $1000 | |
| int $15 { DESQview/TopView give up time slice } | |
| mov ax, $1680 | |
| int $2F | |
| end; |
Note: you can even use INT $2F with AX=$1680 to check if you are running in a DOS x86 VM and other OS checks.

MVVM, MVP, MVC, OOD, etc: it is all about structure and using common sense.
Posted by jpluimers on 2014/12/04
I’ve done partitioned programming (using various layers for different kinds of functionality) for ages.
The first time I can remember of official terms for it, I already used patterns like that for a couple of years.
Back then the parts were from Object-Oriented Design: Peter Coad, Edward Yourdon, back in a time when each part – back then not called common layer – was called “component”: Read the rest of this entry »

Delphi: RandomizeIfNeeded
Posted by jpluimers on 2014/10/07
Calling Randomize too often can make your Random numbers even less random.
Sometimes having the Randomize call in a unit initialization section is not practical.
Hence this little method that I think I first wrote back in the Turbo Pascal days:
procedure RandomizeIfNeeded();
begin
if RandSeed = 0 then
Randomize();
end;

NTCore: interesting site about about system internals and software security
Posted by jpluimers on 2014/09/30
I recently bumped into the NTCore website by Daniel Pisti.
At a client without my own VMs, I wanted to create a DebugBreak like function in Delphi, which I remembered from my Turbo Pascal days to be something like Inline($CC). So searching for both Delphi and INT 3, I found an EXE injection page at NTCore.
In Delphi, you can do this with a procedure like this, which cannot be inlined because it has an asm block:
procedure DebugBreak();
asm
int 3
end;(Reminder to self: sort out what to do here to break on an iOS device; Xcode has an alternative)
The site has information about system internals and software security posted as articles until 2009, when he switched to blog posts. Besides that, he has written a bunch of interesting articles at CodeProject. Read the rest of this entry »

The dreaded with… Debugging today, I found another gotcha (: – via: Lars Fosdal
Posted by jpluimers on 2014/08/12
In the With Statement series:
Lars Fosdal – Code Rants
Debugging today, I found another gotcha.
In this case, both Self and DisconnectedClient has a property named ClientIdentifier.
Note the difference for the mouse-over and the evaluation.

The StackOverflow Pascal/DelphiSyntax Highlighter
Posted by jpluimers on 2014/07/22
Found out where the StackOverflow Pascal has its origins: What happened to comments in syntax highlighter? – Meta Stack Overflow.
Like any syntax highlighter, it is not perfect (only a Delphi compiler driven highlighter would have a chance to be perfect), but it does a pretty good job and gets better over time.
