Dear everyone: Please stop using $IFDEF VERXXX

TURBU Tech – I just checked out the source to a new project.  Not going to name names because what I’m discussing is a pretty universal problem.  This project had dependencies on several common Delphi open-source libraries, and it had a well-designed DPROJ file that got all the paths right and everything. ...

String Hashing Shootout

DelphiTools – Following a recent post by A. Bouchez about an optimized CRC32 hash, I took it as an opportunity to re-run a small String Hashing Shootout on the worst hash function collision torture test I know: ZIP codes in UTF-16 (Delphi’s default String format).

Finally some language-level improvements?

TURBU Tech – It would not be unfair to characterize the last few Delphi releases as All Mobile, All The Time.  And as cool as that is for mobile developers, those of us still working in VCL land have sort of felt like we’re getting the short end of the stick.  The last time anything significant was added ...
