Apart from the very interesting poster: the next stop is RAD Studio 10.1 Berlin Version 24.0.22718.6766.
Apparently, I missed the previous RAD Studio 101. Berlin rumour and Tim Anderson mentioning Berlin in New Delphi and C++ Builder Roadmap promises Linux server support « Tim Anderson’s ITWriting as in the Delphi roadmap for 2016 it’s still called BigBen.
The docwiki start page is there, just not open for the public yet: http://docwiki.embarcadero.com/RADStudio/Berlin/en/Main_Page. Like right before Delphi 10 Seattle, it’s only available for writer, l10n, RADBeta, ConnectBeta, Employee.
Similarly, https://sourceforge.net/p/radstudiodemos/code/HEAD/tree/branches/RADStudio_Berlin/ is not there: it was added 20160311.
Still the TLS issues have not been solved, so the very bad SSLLabs rating of F stays stays the same as at before the start the 10 Seattle era.
Also apart from some comments, there still is no central official statement of the recent web-site breaches.
I’m not sure what an eminent new Delphi version can be of use when you can’t be sure your account data is secure and the product download is valid (i.e. not tampered with).
In other words: would you really trust a new Delphi version? I won’t yet, at least not for now.

Even though as of 12c R1, Oracle supports a row limiting clause, NHibernate 4.2 with Oracle.DataAccess.dll 2.112.3.0 does not support that.
When you let it generate the SQL for a LINQ Take call to limit the number of results, you get an exception like this (full exception and stack trace are below):
System.NotSupportedException was unhandled by user code
HResult=-2146233067
Message=Specified method is not supported.
The place where you Take is important, as this does fail:

Stefan Glienke worded it perfectly: Default(typeIdentifier) is a “magic” function that is implemented into the compiler and causes it to generate the correct code – like for records with managed fields it generates a call to FinalizeRecord and some instructions to zero the remaining fields.

When you have one app.config for your whole set of DTAP environments (develop/test/acceptance production), every once in a while you get this error:
ORA-12154: TNS:could not resolve the connect identifier specified
For this particular setup, it means the replacement of parameters in the app.config with actual values from the DTAP went wrong (or was missing). For that we’ve some steps in both the PreBuildEvent and PostBuildEvent of the .csproj file:
PreBuildEvent:
del "$(ProjectDir)$(TargetFileName).config"
copy "$(ProjectDir)app.config" "$(ProjectDir)$(TargetFileName).config"
PostBuildEvent:
powershell -noprofile -file Replace-Parameter.ps1 -Path "$(TargetDir)$(TargetFileName).config"
The PreBuildEvent looks like it is not needed, but sometimes Visual Studio forgets to perform the copy action.

It seems I always forget about the InternalsVisibleTo attribute which allows you to specify which external assembly can see your internal types and type members:
Internal classes need to be tested and there is an assembly attribute:
using System.Runtime.CompilerServices;
[assembly:InternalsVisibleTo("MyTests")]
Add this to the project info file, e.g. Properties\AssemblyInfo.cs.
Thanks Eric Schaefer for that answer.

I took the liberty to make an English translation of this very interesting German story about squasing an Heisenbug from Kristian Köhntopp: Heisenbugsquashing bei +SysEleven: Sechs Monate Kernels crashen, aber jetzt isser tot….
Don’t forget to read (translated) comments in the original thread. Very interesting read!
I agree it’s in the Heisenbug category given “Time can also be a factor in heisenbugs, particularly with multi-threaded applications.”.
Anyway, the translation and original:

[WayBack] git-extras is awesome: it adds many [WayBack] useful commands to git. Like [WayBack] git ignore and [WayBack] git-info.
For instance, this adds README.md~ to the .gitignore file:
git ignore README.md~
It makes command-line git much more usable, even so much that it lessens the needs of SourceTree and other UIs tools.
You can get it at the GitHub repository [WayBack] tj/git-extras.
Lots of help is at [WayBack] git-extras/Commands.md: it explains all the commands that git-extras adds.
Thanks [WayBack] nifr for posting about git-extras at [WayBack] Is there an ignore command for git like there is for svn? – Stack Overflow.

Initial hack – image via the forums server.
This weekend, the Embarcadero web site was hacked by AnonCoders. Not once (see also [WayBack] G+ link and [WayBack] DelphiPraxis link and [WayBack] image) but at least twice (see also [WayBack] G+ link and [WayBack] image and [WayBack] Delphi Praxis link and [WayBack] image) where the initial hacked simple text “Hacked By AnonCoders ~ Cyber Caliphate” after having been reverted back to the site – hopefully by Embarcadero staff – was replaced with [WayBack] more graphical content later on.
Hack presenting itself in the IDE – image via the forums server.
The Welcome Page inside the Delphi IDE uses the Embarcadero web site, so the Delphi IDE Welcome Page was also affected (see also [WayBack] this G+ link).
Because the IDE uses this on-line content, potentially any code could be executed inside the IDE (apart from that page being loaded over http, so any man-in-the-middle could abuse this, but I digress). This imposes a security risk as many developers run the IDE from accounts having more rights than the average user.

I never had the box, but someone is selling the [Wayback] 10+ kg Borland C++ 3.0 box:
Edit 2022-02-04: the above went away because of link rot, so I replaced it with an Archive.is version as it was copied at [Wayback/Archive.is] My First Windows C++ Application in Ages: Hello World in Win32 with Visual C++ 2010 – Pete Brown’s 10rem.net.
I did a bit of digging ([Wayback/Archive.is] borland c++ box – Google Search) and found [Wayback/Archive.is] Version information for older Borland/Inprise C Compilers has all the product box photos of these products:
Borland C++ 3.1 through 4.5 shipped in huge boxes, each even larger than the before it.
The box with the 1994 Borland C++ 4.5 and Database Tools supported DOS, Windows, and Win32. It had either a CD or 28 3.5″ HD diskettes.
The last version with 5.25″ diskettes was the 1991 Borland C++ 3.1: 15-5.25″ 1.2 Meg. Diskettes or 15 3.5″ 1.44MB disks.
