Based on [WayBack] How can I open a cmd window in a specific location? – Stack Overflow:
cmd /K "pushd ""D:\Versioned Stuff\wiert.me"""
The quoting is required for paths having spaces, so I always include them just in case I ever have a path with spaces.
If I want it with bash, then I run it as follows:
cmd /K "pushd ""D:\Versioned Stuff\wiert.me""" && "C:\Program Files\Git\bin\bash.exe"

While checking out an issue with the SSH server for ContinuaCI issue (see info below), I wanted to look at the files leading to the issue: .pem and .rsa files with the private key for the SSH server.
So I browsed through my series of openssl related articles to see if I already had made a script better explaining the cryptic openssl command-line parameters. I didn’t have it yet, but it turned out to be really simple:
C:\ProgramData\VSoft\ContinuaCI\SSHD>"C:\Program Files (x86)\Git\usr\bin\openssl.exe" rsa -in server_keypair.rsa
writing RSA key
-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----
C:\ProgramData\VSoft\ContinuaCI\SSHD>"C:\Program Files (x86)\Git\usr\bin\openssl.exe" rsa -in server_keypair.rsa -text
Private-Key: (1024 bit)
modulus:
..:..:..:.....
publicExponent: 35 (0x23)
privateExponent:
..:..:..:.....
prime1:
..:..:..:.....
prime2:
..:..:..:.....
exponent1:
..:..:..:.....
exponent2:
..:..:..:.....
coefficient:
..:..:..:.....
writing RSA key
-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----
C:\ProgramData\VSoft\ContinuaCI\SSHD>"C:\Program Files (x86)\Git\usr\bin\openssl.exe" rsa -in server_keypair.pem
Enter pass phrase for server_keypair.pem:
unable to load Private Key

The command-lines use the [WayBack]rsa tool with:
-in parameter-text parameter to dump it into human readable form-passin parameter with a [WayBack] pass phrase argument pass:password.The server_keypair.pem file (having the header -----BEGIN ENCRYPTED PRIVATE KEY----- and footer -----END ENCRYPTED PRIVATE KEY-----) was a password protected RSA private key where somehow ContinuaCI had the wrong password for.
I’m not sure it’s a good idea that the server_keypair.pem file has not password at all.

Odd, the [WayBack/Archive.is] Delphi Intrinsic Routines – RAD Studio indicates quite a few compiler intrinsics are not available on Windows.
I wonder if this list is correct:
Routine Description DCC32 DCC64 DCCOSX DCCAARM DCCIOSARM DCCIOSARM64 DCCIOS32 System.AtomicCmpExchange AtomicCmpExchange is used for comparing and exchanging memory values. System.AtomicDecrement AtomicDecrement is used for decrementing memory values. System.AtomicExchange AtomicExchange is used for exchanging memory values. System.AtomicIncrement AtomicIncrement is used for incrementing memory values. System.BuiltInArcTan Calculates the arctangent of a given number. System.BuiltInArcTan2 Calculates the arctangent angle and quadrant of a given number. System.BuiltInCos Calculates the cosine of an angle. System.BuiltInLn Calculates the natural logarithm of a real expression. System.BuiltInLnXPlus1 Calculates the natural logarithm of (X+1). System.BuiltInLog10 Calculates log base 10. System.BuiltInLog2 Calculates log base 2. System.BuiltInSin Calculates the sine of the angle. System.BuiltInSqrt Calculates the square root of X. System.BuiltInTan Calculates the tangent of X.
Especially since this compiles fine with the DCC32 compiler:
program CompilerIntrinsicsConsoleProject; {$APPTYPE CONSOLE} {$R *.res} var I, J, K: Integer; begin System.AtomicCmpExchange(I, J, K); System.AtomicDecrement(I); System.AtomicExchange(I, J); System.AtomicIncrement(J); end.
