GitHub – oldcompcz/SpaceAssault: DOS space shooter in ASCII.

Posted by jpluimers on 2018/06/05

Cool [WayBack] GitHub – oldcompcz/SpaceAssault: DOS space shooter in ASCII. written in pure C using Turbo C.

You can likely compile this using this:

[WayBack] Turbo C++ or C for Windows 7, 8, 8.1 and 10 32/64-bit Full Screen Free Download – CodePlex Archive

The download is actually a small Windows wrapper around Turbo C++ 3.2: github.com/vineetchoudhary/turbocpp/releases.

Via: [WayBack] Space Assault Game The complete source code of very nice ascii-art invaders is now at GitHub. This game of Roman Hocke won second place in the High-Voltage 2017 competition… – Jaroslav Beran – Google+

Delphi versions that can convert .bpg to .groupproj files

Posted by jpluimers on 2018/06/05

Reminder to self: extend the below very incomplete list of Delphi versions that can open a Borland Project Group file with extension .bpg (from the Delphi <= 7 era) and convert it to an XML based Group Project file with extension .grouproj (from the Delphi >= 2007 era).

  • Delphi 2007

Notes:

The .bpg file is actually a makefile, see for instance [WayBack] build – How to compile a Delphi 7 project group file (.bpg) using the command line? – Stack Overflow

Delphi 2006 and 2005 use .bdsgroup files:

The .bdsgroup files are not compatible with .groupproj files in Delphi 2007 and up: [WayBack] delphi – How to convert a D2009 .groupproj file to a D2006 .bdsgroup file? – Stack Overflow.

A .grouproj file is basically an msbuild 2013 subset, see the below links for more info:

I needed this so I could make this conversion:

PS: Searching for the .groupproj links also got me this: [WayBack] Parallel compilation of delphi projects through MSBuild – Stack Overflow

Field “id” not found, the The Turkish-İ/I/i/ı and case conversion and case folding – Update on the dasBlog Turkish-I bug and a reminder to me on Globalization – Scott Hanselman

Posted by jpluimers on 2018/06/05

Reminder to self: in Turkey, they have more than just the lowercase i and uppercase I. In fact these are the i characters you can get:

Note there are more non-US latin characters in Turkey, see the links below for some lists.

The Turkish case conversion is inside the same group of dotted. The English case conversion is from dotted lowercase i to dotless uppercase I as shown in [WayBack] Internationalizing Turkish: Dotted and Dotless Turkish Letter “I”:

English vs. Turkish Case Mappings
Language Letter Lowercase
Map		 Uppercase
Map
English i i I
Turkish dotted i i İ
Turkish dotless ı ı I

In general, this problem is called [WayBack] Case Folding and many environments do not have good and ready to use solutions for this.

In my case, I was getting Field "id" not found messages for all tables that had an ID field. The reason was that somewhere in the path from my code to the database, either a comparison or case conversion wasn’t taking into account the above mappings.

Though the underlying database indicates I shouldn’t in [WayBack] Do I have to use UPPERCASE identifiers?, it appears that something in the path from my code via IBX to the Firebird 2.5 database has issues on Turkish machines. The good thing: Database WorkBench 5.x doesn’t have that issue for a regular query.

Usually databases are only cases sensitive with quoted identifiers, but not all are: [WayBack] Lorenzo Alberton – Articles – Database identifiers, quoting and case sensitivity
