LOLCODE is an esoteric programming language inspired by lolspeak, the language expressed in examples of the lolcat Internet meme. The language was created in 2007 by Adam Lindsay, researcher at the Computing Department of Lancaster University.

The language is not clearly defined in terms of operator priorities and correct syntax, but several functioning interpreters and compilers exist. One interpretation of the language has been proven Turing-complete.

This article provides non-exhaustive lists of Java SE Java virtual machines (JVMs). It does not include a large number of Java ME vendors. Note that Java EE runs on the standard Java SE JVM but that some vendors specialize in providing a modified JVM optimized for Java EE applications. A large amount of Java development work takes place on Windows, Solaris, Linux and FreeBSD, primarily with the Oracle JVMs. Note the further complication of different 32-bit/64-bit varieties.

The primary reference Java VM implementation is HotSpot, produced by Oracle Corporation.

An article about or described by any of the following can be safely assumed to fit into the set of unnecessary articles:

1. You, your family, or the organization you work for.
2. Your band, which has only sold 47 copies of its one album. Even if you think it will sell 48. Or maybe 49! Or, if you get really lucky, you can pay off the record store owner so that he may buy one and your sales will have gone up to fifty!!! Keep dreamin', brotha.
3. Your imaginary friend or your imaginary friends that don't even exist.
4. The religion, language or even country that you made up with your friends in school one day.
5. The street you live on, unless it is on a Monopoly board. But since it is highly unlikely that you live on a Monopoly game board, we suggest that you not even try.
6. Any one of the 16 distinct regions in the Pokémon video game series or lieking mudkipz, or hering dat someon lieks mudkipz. Remember, not everyone is a Pokémon fanatic.
7. A stunt or trick only you have ever attempted, probably unsuccessfully.
8. Any movie you made yourself which has never been seen by more people at one time than can fit in your basement. Even if you have a really big basement.
9. Individual songs that have never been released as a single nor seen radio play, unless they're twenty minutes long or have led to a phone number becoming unusable or even have questioned the essence of music itself.
10. "(Anything) in popular culture." Anything at all.
11. Likewise "Hysterical Realism in the Works of (insert neither hysterical nor realistic author here)".
12. Your dormitory, university residence, or any suite therein.
13. Stuff nobody but that guy who changes his Spock ears more often than his underpants cares about, or the equivalent thereto. For example, a song about a custom map of a video game, unless you are famous and the song managed to release as a single.
14. Anything about which you cannot be buggered to write one complete sent
15. Subjects that cannot be studied, or the knowledge of which amounts only to the fact that it pertains to another topic. A favourite line from a movie or catchy lyric, a potent phrase used in argument, juicy facts of interest to fans, a punch-line or zinger; these are all very interesting, but usually all that can be informatively written about topic "X" is: "X is a _______ found in _______."
16. Just about everything listed on Wikipedia:Millionth topic pool.
17. For that matter, Wikipedia:Millionth topic pool.
18. Anything about your cat or dog and how cute it is (or your hamster, degu, or chinchilla).
19. Exploding Whales, or indeed Exploding Wales, or even Exploding Wales. Or blowing up any other animals, for example, exploding mice, or even exploding Velociraptor, for that matter. Most things that implode are pretty much off the list too, with a few exceptions.
20. Anything written under the influence of recreational substances or while tired and emotional.
21. An article about another article, written after the use of aforementioned substances.
22. A fork of an existing article for the sole purpose of adding some humor.
23. The weather in London. Not even a redirect. (Wowee).
24. Your guild in World of Warcraft or similar time wasters. Just because you have no life a personally fascinating hobby doesn't mean you get to tell the world about it. And don't write about this guy in your guild who wiped your raid, either.
25. Something you just saw on YouTube and, possibly, laughed at.
26. Something you just put on YouTube.
27. An article that haz badly grammar and/or speelling. Including, bad punctuation!!
28. Any meme, no matter how popular or important.
29. Anything you don't know the title of.
30. Your wiki or blog. It's probably not internationally famous. If it is, well go ahead, but let's face it; your blog of cute cats is not internationally famous (three readers is not fame).
31. Your new invention or research paper that will change the world. It will undoubtedly fail.
32. Anything about your cat named Bubba or your dog named Max. No one cares. Trust us.
33. Your nomination for the Noble (or even Nobel) Peace Prize.
34. Anything about how you were abducted by aliens.
35. An article on the dream you had last night. No matter how long you describe it, it will never be interesting: Even if dreaming that you were the inventor of the chalk board who had to overcome obstacles from the evil book binding lobbyists deeply moved you to tears upon waking up.
36. An article on the person that knocked on your door while you was writing the article about your dream last night, causing you to forget about the dream (but I’ll be honest, I feel for you).
37. An article about Wikpiedia, Wikipaedia, Wiokipedia, Wikipeedia, Wikipeadia, or any other Wikis that appear to be Wikipedia but aren't.

41. Recreating this dumb list.
42. Anything about hashtags. #IHateHashtags
43. Anything about how fat you are or how much weight you're losing (trust us; no one cares).
44. Headlight flashing – I know, it's preposterous, even for Wikipedia. But when you're done laughing and/or crying, follow the link. It really exists.
45. Assumptions about the conclusions of scientific publications that you have seen the titles of, but not read.
46. Your self-published book.
47. McGannahan Skjellyfetti.

49. Lists of times at which commercial breaks occurred during a sporting event.
50. Your personal opinions about your boyfriend or girlfriend.
