1970 Becker Mexico AM-FM Cassette Car Radio showing operation & sound – YouTube

Posted by jpluimers on 2016/07/15

This is the radio in our W116 450SEL 6.9 (pictures are at Flickr: mb450sel69).

Still need to figure out how we can connect a mobile phone or AUX to it.

Research research…

Note there were earlier and later models of this:

This is ours:

FireFox full version direct download link

Posted by jpluimers on 2016/07/15

When firewalls, proxies, etc prohibit the boots-trapper that upgrades an existing Firefox or download stub (like “Firefox Setup Stub 38.0.1.exe”) installs a fresh one to function correctly:

https://download-installer.cdn.mozilla.net/pub/firefox/releases/38.0.1/win32/en-US/Firefox Setup 38.0.1.exe

(replace the version number with the current one; replace spaces with %20 when needed)

Those are the OCR-ed and hand corrected sources from the stack of paper below: chrislgarry/Apollo-11: Original Apollo 11 guidance computer (AGC) source code digitized by folks at Virtual AGC (http://www.ibiblio.org/apollo/).

Interesting trick posted by Lars Fosdal on keeping IDE user specific defines

Posted by jpluimers on 2016/07/13

Via Lars Fosdal:

In Tools|Options, Environment Options, Environment Variables – under User Overrides, add a new override

Variable name: DCC_Define

Variable value: billmeyer

This causes a define for billmeyer to exist for anything that you compile in your IDE, across all units, all projects.

Which means you can sprinkle your code with

{$ifdef billmeyer}{$hints on}{$endif}

or

{$ifndef billmeyer}{$hints off}{$endif}

or even isolate out the parts of the code that currently is in development so that it doesn’t get built in the build system.

I believe it was +Uwe Raabe who revealed this gem to me.

Delphi include files and the search strategy are different for the compiler and IDE

Posted by jpluimers on 2016/07/12

Recently I bumped into a thing that I’d long forgotten: the Delphi compiler treats searching for include files (any files used with the {$I} or {$include} directive differently:

  • The compiler first searches the directory where the file that is including resides and then uses the project and IDE search paths.
  • The IDE only uses the project and IDE search paths.

This means that when you press Ctrl-Enter on the filename to be included you might edit a different file than the compiler will include.

So when a product has multiple include files with the same name in different sub-directories, then you must modify them all.

I’m not sure this is a bug or feature, so Embarcadero is free to put this in either their QA system or documentation system.

Delphi keeping EXE locked; some links

Posted by jpluimers on 2016/07/12

For my own reference when coping with “[dcc32 Fatal Error] F2039 Could not create output file” which happens with a lot of Delphi versions:

As a temporary measure (in the end you have to restart the IDE), I often use Process Explorer to force close the open handles from bds.exe to the EXE.

It also happens intermittently using Visual Studio, where  devenv.exe keeps handles locked. Same Process Explorer trick applies there too.

You can do similar tricks with LockHunter or Handle.exe.

Im memoriam: Gwan Tan, friend, Delphi, Firebird, EKON and Delphi-Tage supporter

Posted by jpluimers on 2016/07/11

Overlijdensbericht Swie Gwan Tan; Eindhovens Dagblad; 20160711

Overlijdensbericht Swie Gwan Tan Eindhovens Dagblad; 20160711

Last friday, my good friend Swie Gwan Tan suddenly passed away. Like most good friends, we didn’t see each other often enough, but when we did it always was like we had last seen each other the day before.

We first met ages ago at early BorCon and EKON conferences: I remember them: Gwan, a little chine guy and a really really tall guy (Edwin) on many conferences. It didn’t take long before we chatted and became friends. It must have been the mid 199os, not even sure which year.

Was it the way he was a people person and both Edwin and me very technical? Or he deep into the database side of things and Edwin/me on the Delphi (and later .NET) side? Or were it the long (usually nights) of discussing all sorts of topics (way beyond software development) with some moderate alcohol intake?

I’m still not sure why. These things happen. The beauty of friendships.

Of course I knew Gwan was ill. More than a decade ago walking became more difficult because of a progressive muscle disease that would not affect his heart. Over time he got bound to a wheel-chair. Somewhere in-between he got a heart condition too.

Gwan stayed imperturbable and optimistic. He was enjoying watching sports (Gwan was – despite living near Eindhoven – a huge fan of AJAX, Edwin of Feyenoord, I didn’t care about soccer at all: we had so much fun!) current affairs and movies keeping in touch with so many people. Irregularly he even managed to visit both German and soccer matches. It was so good to see how he enjoyed those. He was also a great family guy: organising events was his thing. His siblings, nephews and nieces always had a great time when meeting him. And then there were the yearly summer BBQ events in the party: awesome!

So it was only natural that – after we started cooperating with better office Germany – Gwan would organise the Dutch “Knowledge Days” events and the technical guys (usually Edwin and me from the Dutch side and Daniel Magin from better office Germany) would present the sessions.

When better office Germany got in trouble (long story) Gwan asked if I could financially help him to take a stake so at least the German personnel could be payed. We did, lost financially but earned life long friendships (and learned a thing or two on how banks operate).

One of the things with Gwan was that there never was a dull moment and always an opportunity to learn. Even from mistakes. Of course we had words once every now and then. But never a really big fight. I guess that’s part of a good friendship.

Another thing was the combination of being modest about himself and proud about others. For example he always proudly named one of his sisters” my little sister” as he was so fond of what she accomplished.

I vividly remember spring 2009 when – right after the Delphi Live 2009 conference – some USA friends, Edwin and me organised a surprise 50th birthday dinner party for Gwan. Despite his condition, Gwan was really happy that he made it to the conference. So having a party like that was a total blast.

He attended way more conferences and seminars than I did, especially an Germany. Unlike me, Gwan loved driving long distance. So he attended many Firebird, Delphi-Tage and other events I didn’t make it to. When I was at events, I could always spot Gwan with lots of people around him. usually near a bar (:

Around the time Gwan’s mom died about 3.5 months ago he spent some time in hospital to treat the edema that came with his muscle condition. It took a while, but the medicines worked, he attended the funeral and moved to an apartment with facilities for disabled and direct access to care.

Last week he had was hospitalised and his conditions worsened faster than anyone expected. Friday morning he quietly passed away. No more pain. No more sorrow.

Sadly we are left behind, but also pleased that his ordeal is over.

A dear, generous, modest and positive friend is gone.

Attending the funeral service

If you want to attend the funeral service, please let me know so I can inform the family of an attendance estimate.

The funeral service will be held on Thursday morning July 14 at 11:30 at this location (they begin 11:30 sharp, be early!):

Onze Lieve Vrouw Presentatiekerk AalstEindhovenseweg 63
5582 HP Aalst -Waalre
The Netherlands

Phone: +31 40 221 22 85 (preferably between 10:00 and 12:00)

The above catholic church is easy to find as it is right in the center of Aalst-Waalre (see the church icon on the map). They welcome everyone: non-catholics and atheist are equally welcome.

There are parking spots nearby on the south side of “de Leesakker” (right behind Greek restaurant Olympia) or in the street next to Restaurant Lugar (for both, see the P markings on the map).

To stay: look for Hotels near Aalst-Waalre. I can recommend the Van der Valk Hotel Eindhoven as Gwan and I have organised some workshops and seminars there.
