- Sorted map vs hash map ?4
I did a small test to compare performance of TFPGMap and TFPHashList in sequential and random accessing values by keys. http://arbinada.com/main/en/node/1511 The results…
- Sorted map vs hash map ?0
The problem was in the proper generation of random keys for testing. Now it looks better. I added statistics with different key's density ("normal" usage is unique keys)

I believe that since SVN commit 30628 UniversalTimeToLocal(UT: TDateTime) and LocalTimeToUniversal(LT: TDateTime) are reporting incorrect values. The multiple parameter…

I see that according to http://wiki.freepascal.org/Streaming_JSON one can use TStringList for an array of strings, but this seams to work only for writing JSON, is it…
- Re: Delphi mode for new features?2
This is another good example of divergence that complicates the life. Object type can be used as "advanced record" in FPC mode only. I'm agreed that it is good evolution…
- Re: fpc-pascal Digest, Vol 133, Issue 41
I would like to believe it but Embarcadero/Delphi announced the growth of users/client base 2 or 3 years ago, aren't they? Clearly, Delphi is more advanced in GUI…

- Re: Delphi mode for new features?5
Sorry, I didn't understand your point. Out of Embarcadero subject, if 100% convergence is not possible why do divergence? Are you agreed that more FPC is compatible with…
- TDBF licensing12
Am I correct in understanding that TDBF included with FPC is a LGPL licensed component, the one that doesn't have the static linking exception. So I can't use it in any…
- ActiveX units under Linux0
Is it possible to make the importtl tool work under Linux? Is it just a matter of defining a bunch of Windows types? I use Linux for development and cross compile to…
- Floor, Ceil and Int642

- Delphi mode for new features?2
My question is inspired by some things asked here last weeks. As I see (may be mistaken), some _new_ Delphi features are available only in $MODE DELPHI. This way lead to…
