Undocumented Delphi record alignment directive – Chee Wee’s blog: IT solutions for Singapore and companies worldwide

Posted by jpluimers on 2015/12/02

Reading a thread with ramblings on failing to understand that packed records overrides the $ALING directive, I found out that there is also an Undocumented Delphi record alignment directive – Chee Wee’s blog: IT solutions for Singapore and companies worldwide.

David Heffernan mentioned some nice permutations in the first thread.Chee Wee Chua “documents” the second. Both provide great reference material.

Note that both directive require a const expressions evaluating to a power of two. If you don’t, you get the same error: E2573 Illegal value for the ALIGN directive (valid for one of 1, 2, 4, 8 or 16) (Delphi) – RAD Studio

NameBasedSSLVHostsWithSNI – Httpd Wiki

Posted by jpluimers on 2015/12/02

For my link archive:

# Ensure that Apache listens on port 443
Listen 443
# Listen for virtual host requests on all IP addresses
NameVirtualHost *:443

# Go ahead and accept connections for these vhosts
# from non-SNI clients
SSLStrictSNIVHostCheck off

  # Because this virtual host is defined first, it will
  # be used as the default if the hostname is not received
  # in the SSL handshake, e.g. if the browser doesn't support
  # SNI.
  DocumentRoot /www/example1

  # Other directives here

  DocumentRoot /www/example2

  # Other directives here

One more time as WordPress screws XML:

Wish more people named Peter Sollich for what he did in the Pascal world…

Posted by jpluimers on 2015/12/02

A small video reference to the work that Peter Sollich did for the Pascal world is at around 38:20 in this video:

It is where Allen Bauer talks about his early years at Borland. He talks about a German guy there without naming him. It is Peter Sollich (he names them a few time in the newsgroups though).

Peter Sollich came from Germany where he had written a Turbo Pascal compatible compiler for the Atari ST (it used a m68k Motorola 68000 CPU which is a 32-bit processor on the internal side with a 16-bit wide data bus (transporting 16-bit words) on the outside using a 24-bit address (so it can address 16 mebibytes of memory) – hence ST for Sixteen/Thirtytwo).

Borland bought the source code which formed the base for the current 32-bit x86 compiler implementations of both Delphi and C++ Builder (they hired him as a contractor to do the port).

Rumour goes that Peter wrote many parts of the x86 code emitter on the flight from Europe to the USA.

Before the ST era there was already a CP/M Modula-2 compiler written by Peter Sollich and Martin Odersky which Borland bought even earlier and was turned into Turbo Modula-2.

For people interested, here are some links with ore details – where possible I saved them in the WayBack machine as sites tend to Ditch historically important information:
