The Tobin citation comes from James Tobin's Fred Hirsch Memorial Lecture "On the Efficiency of the Financial System" in 1984 [https://economicsociologydotorg.files.wordpress.com/2014/12/tobin-on-the-efficiency-of-the-financial-system.pdf].

The explanation says “allego” and “prologue“ are “musical terms such as may be used in the introduction of a performed piece”. That may be true of “prologue” but “allegro”, according to Wikipedia, is “a tempo marking indicate to play fast, quickly and bright”.

:And, derived from this, a movement of a piece that is performed quickly may be referred to as an allegro. It can also be used to refer to an entire piece, such as this piece by Mozart: [https://www.pianostreet.com/mozart-sheet-music/allegro-k-1-f-major.htm] [[User:Kazzie|Kazzie]] ([[User talk:Kazzie|talk]]) 12:00, 21 January 2019 (UTC)
::But based on the placement of the allego and the way it is written it is most likely a tempo. Tempo goes just above the music and in this case it is the only word on the page that is italicized. [[Special:Contributions/162.158.186.108|162.158.186.108]] 14:09, 21 January 2019 (UTC)

How would this compare with “candlestick patterns” - the bathtub one looks like a funny name for a pattern *meant* to signal that prices could rise https://www.investopedia.com/articles/trading/06/advcandlesticks.asp.

Should we make a table for each term like there is for other comics? [[Special:Contributions/162.158.63.232|162.158.63.232]] 18:01, 21 January 2019 (UTC)
:Yes please. Also, the individual jokes could be explained better. For instance, I'm pretty sure "lumbar support" is there as a joke on the word "spline" looking & sounding a lot like "spine". I'm 90% certain it's a pun, but that's not mentioned yet.

The fundamental problem is that price movements are NOT a random walk. It is safe to assume that people who know a market well will study it, and make purchases/sells based on the underlying market drivers. And in doing so, they will leave "tells" in the pricing data. It becomes possible to look at markets, and see what the people in-the-know are doing, and follow along after them. That is the fundamental basis of technical analysis, and it works -- it works unbelievably well.

If there is a problem, it is that computers can do this pattern recognition so fast that there is longer any room for people to do this.

In other words, computerized arbitrage has gotten so good that people need not apply, and a few high-end groups with high speed electronic trading can get in before any person can.

:Keybounce, do you have any thoughts on how to share some of that with the layperson? The cryptocurrency markets are highly volatile and worth many billions of dollars. People with little resources are getting involved and either going bust or becoming millionaires. The trading history makes it clear there is a lot of automated trading for a long time, but I'm not sure many people really know what they are doing, and the publically available code appears pretty weak. People who contribute resources like reliable public trading bots could make huge impacts on major economic and social groups.

}}

==Explanation==
This comic is a commentary on the practice of [http://www.urbandictionary.com/define.php?term=vaguebooking "vaguebooking"] or [http://www.urbandictionary.com/define.php?term=vaguetweeting "vaguetweeting"], which is posting a short message of sadness or frustration without context.

Google has been criticized more than a few times for keeping rather extensive data records on its users, who by this point constitute most of the internet, enough to cause serious damage if Google wasn't historically altruistic (as altruistic as a for-profit company can be). In the comic, ContextBot is a fictitious Google invention which puts context for these statuses, presumably based on all that personal data which Google has collected:

*The first response is pretty self-explanatory: the original poster wants to use the Internet while on the toilet, but can't get a {{w|wi-fi}} signal there.

*The second response is about a bad {{w|torrent file}} the original poster downloaded. A ''torrent'' is a way to download files from a lot of different sources at the same time, thereby speeding up the process; it is typically used for large downloads such as movies, games, or Linux software distributions. Fake torrents exist, which usually contain an encrypted {{w|.rar}} file which requires a password to open. To get the password, you usually need to go through a survey through the link supplied in the torrent; in some situations, you even need to pay in order to get the password. Even after that, it's quite likely that the .rar file just contains trash files, instead of the download you wanted.

*The third response is about an xkcd favorite, ''{{w|Minecraft}}'', which has been [[861: Wisdom Teeth|referenced]] [[882: Significant|multiple]] [[1110: Click and Drag|times]] in xkcd comics. Diamond is a very valuable resource in the game, and lava destroys any item dropped into it. A "stack" of diamond is 64 individual diamonds, because most items (including diamonds) can only be stacked to a maximum of 64 in the vanilla minecraft. The 64 diamonds likely represents the fruit of several hours (or days) mining.

*The fourth response is about how the original poster mistook the grapes as being seedless. Grape seeds taste really bitter and are uncomfortable when swallowed; this is even more annoying when the seeds are unexpected.

As noted by the subtitle, ContextBot is considered a great good by everyone who was sick of vaguebooking. This also redeems Google's practice of all those data records in the public's eye.

In the ContextBot's avatar image, three people can be seen together hanging out. But the image is about to be cropped, leaving out the third person and therefore giving the impression that the two people in the cropped image are there without that person. This demonstrates how ''context'' is important to understanding a situation.

The title text refers to the cryptic ways in which someone with sensitive information must communicate. While most vaguebooking/vaguetweeting is about things of little importance, the title text implies that the things not mentioned impact national/global security. This implies that many tweets may actually be related to high-clearance military and or national security information, but must be vague in order to keep it secret, and if you take that as the context, then the internet suddenly becomes much more exciting.

==Transcript==
:[A social network feed with four status updates from four different people with profile picture. Each status has an arrow going down and right to a reply underneath them, all from the same account, which is called ContextBot. It also has a profile picture with three people standing behind a see-through material with a hole in it. The person on the left is no behind the part with hole and is thus completely grayed out. The other two only have their legs covered, the rest is thus not grayed out because it is behind the hole. The left is a Cueball, the middle may have glasses, and the right has hair. Below them is a black band in which the name ContextBot is written in white.]
:Close-up face with hair and glasses: The things I put up with...
:ContextBot: (His building's WiFi doesn't reach the bathroom.)
:Cueball and Megan holding each other: You'd think by now I'd have learned never to trust anyone.
:ContextBot: (She downloaded a torrent that turned out to be an encrypted .rar and a link to a survey.)
:Blondie: I officially give up.
:ContextBot: (She hit alt-tab to hide Minecraft at work and accidentally dropped a stack of diamond into lava.)
:Hairy: Sighhhh
:ContextBot: (He thought these grapes were seedless.)

:[Caption below the panel]
:Everyone stopped complaining about Google's data-gathering when they launched ContextBot, a system which replies to vague, enigmatic social network posts with context from the poster's life.
