Much better image quality than the one I saw floating around on G+ a while ago.
Even larger high quality images are at 1 and 2.

The most recent versions of Joe don’t even build from stock in OS X any more and there are no direct installers for them.
But there are two most recent older versions that have installers, and a formula recent brew based HomeBrew installation:
After experimenting for a while without brew preferring the first over second, I’ve installed the the third as:
Before making a choice, you might want to consider reading about joe versions in JOE – Joe’s own editor / … /NEWS.md.
Having a background partially in the Linux world, I tried building joe from source on my Mac following the steps at JOE – Joe’s own editor / Discussion / joe-editor-general:Mac binary for 3.3 does not run on OS/X 10.8. It failed because the Mercurial 3.8 branch required automake and autoconf which are not available on just a Mac + Xcode. So I’m happy that others have bit the bullet and make a good HomeBrew build.
What makes HomeBrew so great is that it is based on a fully versioned git/ruby combination, allows for multiple Python versions, allows for binaries through bintray served bottles and has zillions (well, thousands) of installable formulae, all versioned.

Allen Bauer (ex Delphi R&D team) wrote the brilliant piece about a year and a half ago. We can still dream, right?
Allen Bauer, May 25, 2015
Current working theory ofNullable<T>.
Nullable<T> = record
…
property Value: T read FValue; default;
…
end;Using the
defaultdirective to “hoist” the operators of “T“. Currently thedefaultdirective only works forarrayproperties by “hoisting” the ‘[]‘ operator. Marking a non-array property withdefaultwill make the containing type behave as that type.This, coupled with some intrinsic compiler knowledge of the
Nullable<T>type will makeNullable<T>work without any addition of keywords or other standard functions or procedures.Using the “
default” directive on a non-array property will work for any type, except for having the null-propagation semantics.When considering language features, I try and not only make it work for the intended purpose, but also broaden reach of any supporting feature. In the above scenario, even user-defined operators on “
T” will be properly hoisted and used.
This was part of a very interesting G+discussion at Delphi’s New Feature Desired: Nullable Types and Null Propagation….
It covered topics like these:

Oh nice System.SysUtils.TCardinalHelper.Parse:
class function TCardinalHelper.Parse(const S: string): Cardinal; begin Result := StrToInt(S); end;
Which means you get this nice EConvertError with message ''4294967295' is not a valid integer value'. with this simple test (which doesn’t even reach the Assert):
uses System.SysUtils; procedure Cardinal_Parse_High_Cardinal_Succeeds(); var Expected: Cardinal; Value: string; Actual: Cardinal; begin Expected := High(Cardinal); Value := Expected.ToString(); Actual := Cardinal.Parse(Value); Assert(Expected = Actual); end;
So I write some unit tests (see below) of which helpers for these types fail in one way or the other:
These work for the boundary cases:

Fails in Delphi XE8 with a nice [dcc32 Fatal Error] dcc32_F2084_C2359.dpr(27): F2084 Internal Error: C2359
It is fixed in Delphi 10.0 Berlin, but of course a C2359 search does not reveal that as Quality Portal is behind a wall. So for future reference the bug: [RSP-13471] Int64 for loops can generate Internal Compiler Error – Embarcadero Technologies. Thanks +Stefan Glienke for mentioning the issue.
program dcc32_F2084_C2359;
type
TNumber = Int64; // UInt64; // fails too; other numeric types do not fail. Fails in a unit as well.
TNumbers = TArray;
TNumberRange = record
strict private
function GetLowerBound: TNumber;
public
function Numbers: TNumbers;
property LowerBound: TNumber read GetLowerBound;
end;
{ TNumberRange }
function TNumberRange.GetLowerBound: TNumber;
begin
Result := Default(TNumber);
end;
function TNumberRange.Numbers: TNumbers;
var
lValue: TNumber;
begin
for lValue := LowerBound to LowerBound do
;
end;
begin
end.

Source: The Deadlock Empire
Via: Face the dragon. Learn the ropes of concurrent programming. – Lars Fosdal – Google+
Source code is available and focuses on C#; maybe one day I’ll make a Delphi version: deadlockempire/deadlockempire.github.io: The Deadlock Empire: Slay dragons, learn concurrency!
BTW: a great book (with nice illustrations at both github and kernel.org) is Source: Is Parallel Programming Hard, And, If So, What Can You Do About It? [WayBack]
