Great, now I can't decide how to write the transcript 15:00, 7 February 2018 (UTC)

And I now want a new backpack. I'm fine with the one I have, but *I want a new one dammit!* But I can't decide which one Jdluk (talk) 15:08, 7 February 2018 (UTC)

The knapsack optimization problem is famous for being NP-hard (Knapsack problem). Seems to be an allusion to it. Sebastian -- 15:53, 7 February 2018 (UTC)

Nope, see below. The knapsack problem is about optimizing the amount of stuff put into something, while Cueball goes through a buying decision process. 17:49, 7 February 2018 (UTC)
But the buying decision process could be solved by a variation of the knapsack optimation problem: You can choose several features, but cannot combine all of them. The difficulty would be linear in the number of available backpacks (but this would/could be a very large number - for all the other listed items like car, phone, college, appartment, laptop there is less choice available and the decision can be made way faster) and nonlinear in the number of criteria.

This comic is an illustration of the law of triviality aka the bike-shed effect. 17:42, 7 February 2018 (UTC)

I don't believe the bike-shed effect is related, since that would imply that he is focusing on unimportant issues instead of important ones. In this case, the problem is trying to satisfy a number of important needs that are not fully met by any one backpack, forcing him to decide which can be left unsatisfied by any particular backpack.

Yes, you are right. I had the comparison chart in mind and incorrectly connected the dots here. The correct description of the situation is of course analysis paralysis. Snap decisions apparently aren't infallible, either. :P 19:38, 7 February 2018 (UTC)
Now that you point out your reasoning, I can see where someone might think deciding on a backpack is less important than buying a car or picking a college, which is consistent with the bike-shed effect. You deserve points for thinking of it, even though I think it really is more important to Cueball in this case. In fact, I'm surprised that Cueball didn't have a laptop in hand, calculating a composite feature weighted score per backpack to totally geek things up! ;-) Ianrbibtitlht (talk) 22:05, 7 February 2018 (UTC)

The description completely identifies the author with his figure. Mixes them up. That's very bad form and impolite. -- 21:39, 7 February 2018 (UTC)

On top of that, it makes no sense. Nothing in this comic says anything about laptop choices. 03:08, 8 February 2018 (UTC)
Agree. Removed that part and marked it as incomplete, again. Elektrizikekswerk (talk) 10:03, 8 February 2018 (UTC)
I'm confused by this series of comments. I thought the first one was talking about mixing up references to Cueball and Randall. Then the next comment mentions the lack of content related to laptop choices. First of all, I don't understand how laptop choices are related to the Randall vs Cueball issue (if I interpreted it correctly), and furthermore the bar graph specifically includes a bar for choosing a laptop - that means laptop choices in my book! What am I missing here? Ianrbibtitlht (talk) 14:59, 8 February 2018 (UTC)
I'm too lazy to figure out what you're missing, but if I were to do so, I'd start by checking the edit history to see what the description was like at the time(stamp) of those comments, as maybe it focused too much on laptops or whatever. 15:17, 8 February 2018 (UTC)
It gave lengthy consideration to the difference in length of bars between 'car' and 'laptop', which was probably rather missing the point, which is more that they're all pretty short in comparison to 'backpack'. I'm not sure that does relate to the original point in this thread, hence why the second commenter said "On top of that...". 15:46, 8 February 2018 (UTC)

Do we really need a Wikipedia link to explain what 'yelling' is? Really? 11:50, 8 February 2018 (UTC)

Unless we want to have a link for every word I don't think so. I removed it. Elektrizikekswerk (talk) 12:22, 8 February 2018 (UTC)
Do we really need one for 'all caps'? Linker (talk) 14:04, 8 February 2018 (UTC)
The all caps article explains not only what all caps is, but also its connotation to mean shouting. So I think it's a good inclusion. (Maybe the one for yelling was too much though.) 15:10, 8 February 2018 (UTC)

It is so wonderful to have so many choices. Well, no, not especially. After a point, there is so much to wade through, and the additional does not help much with making a better decision. 02:13, 9 February 2018 (UTC) Gene Wirchenko [email protected]

The 'citation needed' is hilarious to me for some reasons. Whoever added that one needs a gold medal.Boeing-787lover 16:57, 9 February 2018 (UTC)

Actual way to choose backpacks ==

Last week I learned the following: don't buy a backpack unless you have already purchased and used all the items you want to keep in your backpack.

Reason: you don't need to have gazillion pockets if you have a really basic set of items. But you may think your items need many pockets. (talk) 18:11, 4 March 2023 (please sign your comments with ~~~~)
