Adding homebrew to PATH
I installed brew in my new Mac M1 and ask me to put /opt/homebrew/bin in the path, so the right command for this case is: echo “export PATH=/opt/homebrew/bin:$PATH” >> ~/.bash_profile && source ~/.bash_profile

Always use parseInt with a radix (base) as the second parameter, or you will get unexpected results: var number = parseInt($(this).find(‘.number’).text(), 10); A popular variation however is to use + as a unitary operator. This will always convert with base 10 and never throw an error, just return zero NaN which can be tested with …
Simply checks for nil and if length of text length is greater than 0 – not empty if (textField.text && textField.text.length > 0) { /* not empty – do something */ } else { /* what ever */ }
So how can I properly save the results of the operations in variable names based on the list I iterate over? You don’t need to. Variables registered for a task that has with_items have different format, they contain results for all items. – hosts: localhost gather_facts: no vars: images: – foo – bar tasks: – …
You cannot override variables in C#, but you can override properties: public class Item { public virtual string Name {get; protected set;} } public class Subitem : Item { public override string Name {get; protected set;} } Another approach would be to change the value in the subclass, like this: public class Item { public …
A variable, as you can guess from the name, varies over time. If it doesn’t vary, there is “no loss”. When you tell the compiler that the value will not change, the compiler can do a whole bunch of optimizations, like directly inlining the value and never allocating any space for the constant on the …
1) Select the variable you want to change, then Press CTRL + R 2) Enter the new variable name you want. (in replace by) 3) Replace all
I don’t know, but you can easily create a workaround like this: int *var = (int*)0x40001000; *var = 4; It’s not exactly the same thing, but in most situations a perfect substitute. It will work with any compiler, not just GCC. If you use GCC, I assume you also use GNU ld (although it is …
