Should I use "did you know" or "do you know" to introduce a fact? I've only seen "did you know" in action. My logical deduction is that before the "question" (which is not much of a question because you're not asking for an answer), you wouldn't have been sure whether the listener'd known about what you're about to say or not.
Know in (1) refers to the clause that comes right before it, so there's no pronoun necessary -- it's essentially a transform of I know it's your job. In (2), however, the object of know is not indicated, as you point out, so something must be provided.
I already know how to turn on the television. I know how to drive a car. You would use the present perfect to express something that happened previously, without specifying the time. You'll only use the present perfect and "already" when expressing previous events relative to the present. I have been to France before.
Recently one of my friends told me that there is distinct difference between 'know of something' and 'know about something' expressions. 'know of' is used when you have personal experience with wha...

In my understanding, ' as we know it ' usually follows a noun phrase and means like The building as we know it = the version/condition of the building we know now. First, I'm not sure about its grammar. Is the 'as' a conjunction? Is it correct to think that 'it' changes to 'them'? E.g., the buildings as we know them Second, a question about its use.

What is the correct usage of phrase "you don't know what you don't know"? Can it be used in formal conversation/writing?
It's not just you that doesn't know. Now, according to owl.purdue.edu, we should use "doesn't" when the subject is singular (except when the subject is "you" or "I"), and "don't" otherwise. But in the example above, I am having a hard time figuring out what exactly the subject is and whether it is singular.

Possibly, "I do know that" can in fact only be used, when, you are answering the question of whether or not you know the issue at hand (or your knowledge has been called in to question, and you are answering that challenge). Let's say "out of the blue" you wanted to state that "you know that" -- and you wanted an emphatic version.

When someone makes an assertion, the distinction between "how did you know" and "how do you know" seems to be that "how did you know" implies that the person in question is correct in their assertion. "How do you know" is normally an inquiry into the person's credentials, and often expresses that the assertion is incorrect and/or ungrounded.

The ::before notation (with two colons) was introduced in CSS3 in order to establish a discrimination between pseudo-classes and pseudo-elements. Browsers also accept the notation :before introduced in CSS 2.
The :before and :after pseudo-elements inherit any inheritable properties from the element in the document tree to which they are attached. For example, the following rules insert an open quote mark before every Q element.
So I read the docs and probably understand the purpose of ::before and ::after. If my understanding is correct, they should always work in combination with other elements. But the web page I'm look...

.icon-cut:before { content: "\f0c4"; } So if you are looking to add the icon again, you could use the ::after element to achieve this. Or for your second part of your question, you could use the ::after pseudo element to insert the bullet character to look like a list item. Then use absolute positioning to place it to the left, or something ...
The code marked @Before is executed before each test, while @BeforeClass runs once before the entire test fixture. If your test class has ten tests, @Before code will be executed ten times, but @BeforeClass will be executed only once. In general, you use @BeforeClass when multiple tests need to share the same computationally expensive setup code. Establishing a database connection falls into ...
