What sense of "hack" is involved in "five hacks for using coffee filters"?

I was drawn to the usage of the word, “hack” in the following message in today. com: 5 unexpected ways to use coffee filters (that have nothing to do with coffee)

Coffee filters are good for more than your morning brew. Try these five hacks and you'll never look at those pieces of paper the same way. That little piece of paper powers our days through the simple task of straining coffee grounds, but that's not the only function it's good for. Here are five new ways to make them even more essential.

As I saw the word, “hack” being used in this way for the first time, I consulted dictionaries on line, and found that:

Oxford Dictionary defines “hack” as a noun to mean:

1.rough cut, blow, or stroke. 2. an act of computer hacking.

Cambridge Dictionary only shows the definition of “hack” as a verb: to cut into pieces in a rough and violent way, often without aiming exactly.

Though I presumme "hack" in the above quote means an idea or method, what does it exactly mean?

Is it common to use "hack" in such a way?

From Wiktionary's entry on hack

(colloquial) A trick, shortcut, skill, or novelty method to increase productivity, efficiency or ease.

Putting your phone in a sandwich bag when you go to the beach is such a great hack.

It's related to the use of "hack" to mean getting unauthorised access to a computer system, because both involve skill.

This particular use of the word 'hack' is fairly recent and is a consequence of the insatiable demand for content to fill blogs and social media posts to attract people to monetised sites stuffed with advertising AKA 'click bait'.

The idea is that if you can create a headline post on a well trafficked platform (like Facebook) which sounds interesting you can encourage people to click on a link to a page with lots of pay per click ads and thus make money.

The original use of the word stems from computers and technology where it referred to an oblique or creative way to modify or exploit hardware or software in a away not intended by the original designer to either customise it for particular purpose or gain some other benefit such as access to privileged information.

at some point (certainly by the mid 1990s 'hacking' was widely understood in popular culture as 'gaining unauthorised access to computer systems'.

Later, especially via the internet community on forums and you-tube etc 'hack' started to take on a more practical aspect often using creative but low tech ways of modifying consumer goods or scratch building useful items from readily available parts. Obviously this had been going on for a long time before this, for example model makers adapting and modifying parts form various model kits to make unique things and words like 'kitbashing' have been used to describe this.

However in this context it is more about an easy way to generate what might be loosely called 'journalistic content' although this process has some history as filler for magazines etc where it would historically be called 'hint', 'tips' etc. The implication being that you are being given access to specialist insider knowledge to make your life easier.

The reality is that these 'hacks' are generally pretty inane and trivial on the same sort of level as '12 historical facts which will blow your mind' and 'this one secret will help you burn belly fat'.

The obvious source for a definition is The New Hacker's Dictionary:

hack

1. /n./ Originally, a quick job that produces what is needed, but not well.
2. /n./ An incredibly good, and perhaps very time-consuming, piece of work that produces exactly what is needed.
3. /vt./ To bear emotionally or physically. "I can't hack this heat!"
4. /vt./ To work on something (typically a program). In an immediate sense: "What are you doing?" "I'm hacking TECO." In a general (time-extended) sense: "What do you do around here?" "I hack TECO." More generally, "I hack 'foo"' is roughly equivalent to "'foo' is my major interest (or project)". "I hack solid-state physics." See Hacking X for Y.
5. /vt./ To pull a prank on. See sense 2 and hacker (sense 5).
6. /vi./ To interact with a computer in a playful and exploratory rather than goal-directed way. "Whatcha up to?" "Oh, just hacking."
7. /n./ Short for hacker.
8. See nethack.
9. [MIT] /v./ To explore the basements, roof ledges, and steam tunnels of a large, institutional building, to the dismay of Physical Plant workers and (since this is usually performed at educational institutions) the Campus Police. This activity has been found to be eerily similar to playing adventure games such as Dungeons and Dragons and Zork. See also vadding.

Constructions on this term abound. They include 'happy hacking' (a farewell), 'how's hacking?' (a friendly greeting among hackers) and 'hack, hack' (a fairly content-free but friendly comment, often used as a temporary farewell). For more on this totipotent term see " The Meaning of 'Hack'". See also neat hack, real hack.

This might not be on the EL&U list of good, standard, commonly-available references, but it’s the right place to go for this question, and Hot Licks opened the door: The Jargon File is basically the original incarnation of The New Hacker’s Dictionary, dating to 1975.  (This is claimed by The Jargon File’s Revision History, which is replicated in The New Hacker’s Dictionary and copied into Wikipedia.  Also, I can personally attest to seeing The Jargon File in the 1970s.)

The Jargon File contains a definition of “hack” that appears to be identical to the one posted by Hot Licks (except it is formatted more readably, with line breaks), so I will not quote it.  Except for the last two sentences, which Hot Licks quoted without copying the links:

The Meaning of ‘Hack’, a component of Appendix A. Hacker Folklore, is approximately 250 lines, mostly comprising some amusing anecdotes.  (Only half of them are computer-related, only one is computer-security-related, and one of them dates back to 1961.)  But the most important line introduces the second paragraph:

Hacking might be characterized as ‘an appropriate application of ingenuity’.

The entry for neat hack says:

1. A clever technique.
2. A brilliant practical joke, where neatness is correlated with cleverness, harmlessness, and surprise value.

(The entry for real hack is mildly scatological and is not relevant here.)
