When archiving pages in the WayBack machine, despite Privacy Badger having set to “save no cookies”, it still managed to set truckloads of cookies.
So I used the Chrome settings in chrome://settings/content/cookies to disable cookies and now everything is fine.

Since I always get confused by the differences in Excel versions (not just between Mac OS X and Windows):
In Excel for Mac, you can adjust where automatic page breaks occur, add your own page breaks manually, and remove manual page breaks.
Source: [WayBack] Insert, move, or delete page breaks in a sheet.

I forgot it was released, but then found back an old note to check it out:
[WayBack] Is This the Life We Really Want? : Roger Waters : Free Download & Streaming : Internet Archive
I quick listen to a few tracks reminds me of The Wall.

Stefan Glienke shared the TestInsight default JSON web-server location with me through chat; I like it!
Some endpoints:
{"SelectedTests":[]}{"SelectedTests":["Test.Timer.TTimerTest.TestBasic","Test.Timer.TTimerTest.TestDifferentIntervals","Test.Timer.TTimerTest.TestWakeUpTimer","Test.Timer.TTimerTest.TestTimeIsInRange","Test.Timer.TTimerTest.TestMilisecondsToNextTriggerTime"]}{"ExecuteTests":true, "ShowProgress":false}The mechanism for accessing this JSON server are implemented in the TestInsight.Client.pas
You can find the endpoint base URL in TestInsightSettings.ini which by default looks like this:
[Config] BaseUrl=http://WIN10-DELPHI:8102

The function or command was called as if it were a method. Parameters should be separated by spaces. For information about parameters, see the about_Parameters Help topic.
Every now and then I bump into the above error. The reason is this:

If I ever need to use SHA-3 in Delphi: [WayBack] Does anyone know of any implementations of SHA-3, that can support TStream? – Nicholas Ring – Google+
The comments have a nice list of libraries supporting SHA-3, and how to do streaming hashing.

I learned this the hard way: [WayBack] Different result when using -ReadCount with Get-Content: because -ReadCount delivers data in chunks, the filter after [WayBack] Get-Content (Microsoft.PowerShell.Management) it will only filter on those chunks. If the filter isn’t prepared for that, it might only filter the last chunk.
So do not use for instance [WayBack] Select-String (Microsoft.PowerShell.Utility) on it, but perform your own [WayBack] ForEach-Object (Microsoft.PowerShell.Core) aliased as foreach like in [WayBack] Get all lines containing a string in a huge text file – as fast as possible?:
Get-Content myfile.txt -ReadCount 1000 | foreach { $_ -match "my_string" }
A more elaborate example is at [WayBack] How can I make this PowerShell script parse large files faster?.

One of the things when I learned Python was that in some scripts I found a block starting with a statement like this:
if __name__ == '__main__':
It looked like an idiom to me, and indeed it is: [WayBack] What is ‘if name == “main“‘ for?.
It allows a file to be both used as “main” standalone program file and a module. That section of code will not be executed if it is loaded as a module.
Part of the idiom is also to put your code in a separate method so this block is as short as possible.
if __name__ == '__main__':
main()
Via: [WayBack] Why is Python running my module when I import it, and how do I stop it? (thanks user166390 and Jeremy Banks for the answers there)

In case you maintain code in older versions of Delphi, be aware that the function tanh was broken starting in Delphi 7 and only got fixed in Delphi XE2: QualityCentral QualityCentral 56524: tanh function from Delphi 7 till Delphi XE was buggy; XE2 fixed it.
For big inputs, it would just fail, instead of returning 1.
The reason is that in the buggy versions, tanh got replaced from an old working version into a simple sinh/cosh, which mathematically is correct, but if your numeric data type has limited accuracy, you need to account for the boundaries where the result fits, but intermediates do not.
the [WayBack] Math.Tanh Function implements the hyperbolic tangent, for which you can find the definition at Hyperbolic function – Wikipedia: Definitions.
By now it is implemented for all floating point types the same way (only the parameter type changes in each implementation)
function Tanh(const X: Extended): Extended; overload;
const
MaxTanhDomain = 23;
C1of3 = 1/3;
CBorder = 1.8145860519450699870567321328132e-5; // 2 ^(-63 / 4)
CLn2Div2 = 0.34657359027997265470861606072909; // Ln2 / 2
var
y, z: Extended;
begin
FClearExcept;
case TExtendedRec(X).SpecialType of
fsPositive,
fsNegative:
begin
z := X;
if X < 0 then z := -z;
if (z > MaxTanhDomain) then
Result := 1.0
else if (z < CBorder) then
Result := z - z * z * z * c1of3
else if (z < CLn2Div2) then
begin
y := ExpMinus1(2*z);
Result := y / (2 + y);
end
else
begin
y := Exp(2*z);
Result := 1 - (2/(y + 1));
end;
if X < 0 then Result := -Result;
end;
else
Result := X;
end;
FCheckExcept;
end;
