call a static method inside a class?
...o the most common way of calling a static method:
self::staticMethod();
Now, before you start thinking that the :: is the static call operator, let me give you another example:
self::bar();
This will print baz = 1, which means that $this->bar() and self::bar() do exactly the same thing; tha...

...e directory.
cp /c/Users/Yuci/.ssh/github_rsa /c/Users/Yuci/.ssh/id_rsa
Now when I run ssh -vT git@github.com again, I have:

Does setting Java objects to null do anything anymore?
...ue. Basically, because you've preallocated an array, the VM sees that. It knows nothing about the "logical" size of your container. Say you have an ArrayList of size 10, backed by a 16-element array. The VM can't know that items 10..15 aren't actually used; if those slots have contents, they will no...
What happens if you static_cast invalid value to enum class?

So a sane default (if such can be claimed) could be Read Committed, which only lets you read values which have already been committed by other running transactions, in combination with a propagation le...
What is the difference between `sorted(list)` vs `list.sort()`?
...ontent is still the same.
nums
[-3, 1, 4, 5, 7, 8, 9, 14]
nums.sort()
Now the original nums list is changed and looking at nums we see our original list has changed and is now sorted.

“git rm --cached x” vs “git reset head -- x”?
... commit it, you add it to the tree as well.
It will probably help you to know the three more common flags in git reset:
git reset [--<mode>] [<commit>]
This form resets the current branch head to <commit> and possibly
updates the index (resetting it to the tree of <...
Why is it bad style to `rescue Exception => e` in Ruby?
...thing else".
Generally, don't do that, except in special cases where you know you don't need to worry. One example:
debugger rescue nil
The debugger function is a rather nice way to set a breakpoint in your code, but if running outside a debugger, and Rails, it raises an exception. Now theoret...
