And Sometimes I Wonder About You

and sometimes i wonderabout you represents a topic that has garnered significant attention and interest. Logical operators ("and", "or") in Windows batch - Stack Overflow. How would you implement logical operators in Windows batch files? What is Python's equivalent of && (logical-and) in an if-statement?. Building on this, there is no bitwise negation in Python (just the bitwise inverse operator ~ - but that is not equivalent to not). Unary arithmetic and bitwise/binary operations and 6.7.

Binary arithmetic operations. Building on this, the logical operators (like in many other languages) have the advantage that these are short-circuited. That means if the first operand already defines the result, then the second ...

Difference between & and && in C? Additionally, the & operator performs a bit-wise and operation on its integer operands, producing an integer result. Thus (8 & 4) is (0b00001000 bitand 0b00000100) (using a binary notation that does not exist in standard C, for clarity), which results in 0b00000000 or 0.

The && operator performs a logical and operation on its boolean operands, producing a boolean result. Equally important, thus (8 && 4) is equivalent to ((8 ... Regular Expressions: Is there an AND operator? Obviously, you can use the | (pipe?) to represent OR, but is there a way to represent AND as well? Specifically, I'd like to match paragraphs of text that contain ALL of a certain phrase, but in no Can I get "&&" or "-and" to work in PowerShell?

It's important to note that, instead, you can save this post to reference later. Moreover, aND OR order of operations - Stack Overflow.

In the normal set of boolean connectives (from a logic standpoint), and is higher-precedence than or, so A or B and C is really A or (B and C). Wikipedia lists them in-order. Most programming languages should obey this convention unless they are really weird.

That said, for your particular language or environment it should be possible to concoct a very small test to satisfy yourself that it is ... What are the differences between .pem, .cer, and .der?. It's important to note that, to use the public key contained in the certificate (and signed by the signature in the certificate) you should use any library that parses X.509 certificates and performs RSA encryption. You could use a tool that detects/handles PEM encoding or you could first convert the certificate to DER by stripping off the PEM encoding.

The OpenSSL command line contains lots of options to convert between ...
