Wine 10.10 claimed that a 32bit #Delphi app was 16bit. After hunting down that issue(Wine source, WINEDEBUG= all) I found a very old Delphi component pack that imported FreeLibrary16 from kernel32.dll via index 36. Wine redirects this to krnl386.exe16, in Windows=>wrong function

It took me almost 2h to realize that the newest Windows 11 update changes the color of the drive usage bar in Explorer. And I thought some program, I recently installed, was the culprit and I tried to get the lighter blue color (RGB 38,160,218) back. (New color: 0,112,203).

AMD's Chipset Driver installer still requires you to have the "VBScript" feature installed, otherwise it tells you that you don't have an "AMD system" and fails. Maybe somebody should tell @AMD that Microsoft has deprecated VBScript and is going to remove it from Windows 11.

A new bug fix release of IDE Fix Pack 6.5.1 (2009-10.3) is now available. This is especially for Delphi 2010 users.

Sometimes I really wonder what #Delphi "thinks" by generating such unnecessary push/pop code.
mov eax,[ebp $08]
add eax,ebx
push eax ??????
pop eax ??????
xor edx,edx
div esi
or ecx,eax

Will there ever be a 64bit Delphi IDE or at least a LargeAddressAware version. Our Projekt crashes the IDE between 14-18 compilations because it runs out of memory. Maybe I have to patch the IDE myself by moving all .NET and Compiler memory allocations above the 2 GB address.

While trying to apply that patch to the various Delphi versions, I found out that starting with Delphi 10.0, the IDE already can handle large (>2GB) addresses and also the 2 address-calc bugs in the compiler were fixed. Providing the patch only for old IDEs makes it much easier.

The same project compiled in Delphi 2009 IDE with some patching done to allow up to 4 GB address space.

Delphi compilers that are supported by IDEFixPack need an address calculation fix in IDEFixPack (only fails if LargeAddressAware is enabled). And newer Delphi compilers inherited that bug from IDEFixPack and need a new patch.

Fun Fact: The compiler and the .NET memory manager allocate memory pages in 64K blocks.

Address space after compiling a very large project in the Delphi 2009 IDE. (White is the free memory)

Eventually I found time to build the binary JCL and JVCL installers for #Delphi 11 Community Edition. Don't ask for Delphi 12, there is no Community Edition yet.

Netflix's web page in Edge with an active fTPM (AMD) is unusable. Chrome doesn't have that problem. (different DRM). I hope AMD's next BIOS update really containts a fix. (amd.com/de/support/kb/faq/pa…)

Working in #FreePascal/Lazarus I have to constantly remind myself that "string" means "ShortString" and not "AnsiString/UnicodeString". {$mode objfpc}

Three developers had to analyze why the database became slow as he** during a planed performance test. In the end it turned out that the data center moved the VM (that was marked as a "performance test environment") to the slowest HDD storage server they had without telling us.

Maybe I should allocate some (not available) spare time to making major changes to the #IndyComponents and create PRs. But they would be enormous and reviewing them would cost probably days. #Delphi

When you wonder where your app hangs and it turns out that it is busy moving memory around in the Indy-InputBuffer. Why is it even 160 MB large. Oh the TcpClient.Connected method reads 32k every time you call it. Maybe it should try with 1 byte instead of a full RecvBufferSize.

#Delphi #IndyComponents can you please not copy my data around as if there is no tomorrow. Just send my data to the socket. TBytes was a bad idea. Unnecessary zero-init when overwriting it immediately, no pointer arithmetic to move the start resulting in copying TBytes everywhere

I have created the JCL and JVCL binary installers for #Delphi 10.4 from the GitHub main branch. So if you can't use the regular source code installer, you can use those to install the JEDI libraries.
