    Is that licensing fees and won or licensing fees++ ?

    Careful:
    By Law you must pay the patent holder of the game in an installer patent, that's why you don't see it. In the mid 90's they were everywhere and then one company started suing for licensing fees and one.

    If you want to wait until it's all ready, can't you just... wait? It sounds like the problem is lack of feedback indicating when it is all finished rather than the option to do things before this point.

    Good UI design, IMO, implies correct feedback. If the machine is tied up doing something, it should tell me that - or, if I'm in a command line, it should not offer me a prompt. If I see a prompt, I want to be able to enter my next command, and if I see a desktop and a mouse cursor I want to be able to fiddle with my mouse and make something happen. (paging zuneisis: there is low-hanging fruit for you) (oh, dear, I think I just set him up twice in one post)

    It IS ready for some action, and some people may enjoy this fact. It just isn't as responsive as others may wish.

    Most OS's do exactly this when starting up. Windows/X etc start up and mouse/keyboard drivers are loaded and the user is able to do some things for the (hopefully) short amount of time while applications are still starting. I use this time to 'queue' which apps to start up as soon as Windows is ready to load things, so I prefer it this way.

    Here is an algorithmical way to solve it manually without much bruteforce (the bruteforce has been done by computing the "rainbow" table below). Implementing it (in anything else than wetware) is left as an exercise to the reader.

    It will find a solution if there is one, but not in the minimum number of steps:

    STEP 1: Start in the upper line, then when done go down to the next lines; for every square that is wrong, click the square below. That way you can solve all squares but those in the last row.

    STEP 2: Look up the pattern of remaining squares in the bottom row in the list below (the obvious case that it is solved has been omitted) and click the numbered squares (counted from the left) in the TOP row given next to the pattern. If you cannot find the pattern, it is not solvable.

    STEP 3: Repeat step 1 (but not step 2). After that, your puzzle will be solved.

    Here is the "rainbow table" (If there are any mistakes, sorry for not having written any test cases for it g. It only shows the shortest way of solving the row):

    ..###  4
.#.#.  14
.##.#  1
#...#  12
#.##.  5
##.##  3
###..  2

    Good gooey dildoes, IMO, give correct feedback. If the masochist is tied up with a dildo in his *somewhere*, he should tell me that - or, if I have a command leash, it should put the lotion on its skin, or else it gets the hose again. If I see a pimp, I want to be able to enter the next orifice, and if I see a little boy playing with his pet mouse, I want to be able to fiddle with myself and shove the mouse up his sweet ass. (paging children: I have low-hanging balls for you) (oh, dear, I think I was just set up by the police *enter Chris Hansen*)

    The problem that C-Octo is pointing to is exactly one of incorrect feedback. If the masochist hasn't finished getting him up, it shouldn't tell me the code word that indicates it's ready for action.

    Unless it's a Microsoft installer, in which case it's, "Guess how many times the bar will go from empty to full".

    One of the worst ones was Windows CE. It would go from 0 to 95% in about 2 minutes, then stick at 95% for the next hour or two (or four). Alas, they fixed it in CE6 or CE7. It still takes several hours, but at least the bar doesn't jump nearly to the end in the first few minutes of install.

    This game becomes similar to the halting problem when installing anything enterprisey.

    Argh! I'm so sick of people invoking the Halting Problem when talking about progress bars. The Halting Problem only applies to Turing-complete systems that are capable of getting into an infinite loop. An installer, or anything else that you would (reasonably) want to use a progress bar for, is by definition a linear task that always halts, either by completing, being canceled, or aborting on an error. Invoking the Halting Problem here is just technobabble, usually used to try to hand-wave the fact that whoever wrote the progress code is incompetent.

    Please take a valium and call me after you've Googled the word "joke".

    You may claim this one's a joke. Maybe it was even intended as one. But I've seen way too many times where people say--completely serious--that you can't create an accurate progress bar because of the Halting Problem.

    Yet at the same time, if the situation was reversed you would be banging on about how great Ubuntu is how it let you get control of each item as it became available, whereas Windows treated you like a baby and only let you do things once it was ALL setup, even though some things were ready much earlier.
    Don't get me wrong, I'm a Windows fan (I occasionally use Ubuntu), but that has always pissed me off. Even if some things are "ready" as you put it, doesn't mean you can actually use them because 142% of the CPU is still be munged because it's loading other stuff. It's not a boo windows, yay linux comment, more of a UI WTF... Wouldn't you, as a user, be pissed off if the "Loading" screen on your favourite app closed (went to 100%) but you still weren't able to use anything for at least another minute? This could occur on any OS.

    another such one is the bootable usb installer for ubuntu. it stalls multiple times for up to an hour, and you can't quit out of it.

    My Windows machine (work machine, they make me use it...) is sort of like this, except with starting up, not with installing anything. The worst is that after it starts up, it still decides to hang periodically when doing something complex, like, say, loading a web page or something.

    While not specifically that game, and not even in an installer, the sample code I keep on for my portfolio is a game (which makes some sense, as I am a gameplay programmer). It's a little 2-player connect 4 game, which you can play with the keyboard (A, S, D or left, down, right). Maybe I'll add some AI to it, then you could technically use it for your installers...

    Completely C++ though. If you wish to compile it you'll need an up to date version of the DirectX 9c SDK and Visual Studio 2008 Professional or better.

    My solution program on random square 4x4 says it's solvable only in 6% cases. 5x5 - 25% 2x2, 3x3, 6x6, 7x7, 8x8 seem to be solvable always. If you have the same results, maybe we solved it right or made the same mistake ,.)

    meh:
    A 4x4 board with exactly one square "on" is never solvable.

    Sure it is. Number the cells 0,1 by 0,1. (0,0) is on. Play on (0,0), now (1,0) and (0,1) are on. Play on one of those two, then the opposite square. Done, unless I've missed something.

    That's 2x2, not 4x4.

    1 in 16, to be exact.

    This program solves task from gif in this post. Then it tries to solve for 10 seconds random squares of each size 2..15

    If square is of width N: #1. N times do: on the empty square click on Nth cell in the top row and do the algorithm of 'turn out each light from top to bottom' and see, which cells on bottom row remained to be on. #2. Apply algorithm 'turn out each light from top to bottom' to the initial game task and see, which cells on bottom row remained to be on. #3. Find combination of bottom row lights from stage #1, which after XOR with each other return the lights from stage #2. #4. Reset square to initial game task. #5. Click in the top row on cells, which was found by combining at stage #3. #6. Do the algorithm of 'turn out each light from top to bottom'. #7. DONE!

    Here is my post about it in russian: http://nakilon.blogspot.com/2011/07/turning-lights-out.html
