I've been unable to confirm this so I'm moving it here: A major problem had struck IBM mainframes on and after August 16, 1972 (9999 days before January 1, 2000) that caused magnetic tapes that were supposed to be marked &amp;quot;keep forever&amp;quot; instead be marked &amp;quot;may be recycled now.&amp;quot;{{Actual citation needed}} [[Special:Contributions/172.71.158.231|172.71.158.231]] 07:37, 12 November 2022 (UTC)&lt;br /&gt;
&lt;br /&gt;
Does the arrow move over time? ... should it? (I think so!) It could be done server side and only regulars would [see, sic] that it changes over time. Then... perhaps we could see different versions of the strip cached on the Internet. --[[Special:Contributions/172.71.166.158|172.71.166.158]] 08:30, 12 November 2022 (UTC)&lt;br /&gt;
It isn't, of course, but if it was a .GIF with ultralong replace-cycles then only those who ''kept the image active'' would see the arrow move in real-time. (It would reset to ''now's'' &amp;quot;now&amp;quot; upon each (re)loading, so it would have an even more exclusive audience, aside from those that cheat with image(-layer) editing. ;) ) [[Special:Contributions/172.70.162.57|172.70.162.57]] 13:32, 12 November 2022 (UTC)&lt;br /&gt;
&lt;br /&gt;
Should we mention anything about that it is that specific year in a specific calendar? As far as I know there was also {{w|Japanese_calendar_era_bug|fear of a similiar bug in Japan}} recently. However Wikipedia seems not to be up to date about it. --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 15:18, 12 November 2022 (UTC)&lt;br /&gt;
&lt;br /&gt;
Does anyone know of an actual program or OS that stored the year as two characters instead of a single byte? I have (and had back then) serious doubts that any problems existed. Even the reported government computers had people born prior to 1900 entered, so they already had to have better precision than &amp;quot;just tack on 1900.&amp;quot; Even using a single signed byte would still have been good for another 5 years from now. [[User:SDSpivey|SDSpivey]] ([[User talk:SDSpivey|talk]]) 17:22, 12 November 2022 (UTC)&lt;br /&gt;
:In my experience (I lived and worked through the Y2K preparations) it wasn't so much &amp;quot;an actual program&amp;quot;, or necessarily a fundemental limitation of an entire OS (though the roots of the problem effectively date back to key decisions surrounding the developmet of the IBM System/360 in the 1960s), but a matter of how data was held in human-readable but space-saving format. Someone in the '70s (or even up into into the '90s) may have decided their system could store some date as the six characters representing DDMMYY (or ay of the other orders) secure in the knowledge that the century digits were superfluus - and would have perhaps sent the footprint of a standard record over some handy packable length for the system, say 128 bytes. Which was a lot in those days.&lt;br /&gt;
:(If the year ''value'' had been recorded in 16bit binary, or even 2x7bit or doubled 6-bit, it could have been as good for the computer, but ''oh the fuss'' to convert to and from a human-orientated perspective. And it worked neatly enough, right?)&lt;br /&gt;
:And a useful implementaion might be used, in some form or other for a long time... Sometimes the storage system is upgraded (kilobytes? ha, we have megabytes of space now!) and the software to handle it might be ported and even rewritten, but at each stage the extra data has to match the old program, and the new program has to read and write the current data, however kludged it actually is. And it works, at least under the care of those who dabble in the dark arts of its operation. And not many others are bothered or even have any idea of what ;ies beneath the surface.&lt;br /&gt;
:Until somebody starts to audit the issue and asks everyone to poke around and check things... Thenthings get sorted in-situ ''or'' a much needed (YMV!) change of process is swapped in, in the place of old and (possibly) incorrect hacks. [[Special:Contributions/172.69.79.133|172.69.79.133]] 20:00, 12 November 2022 (UTC)&lt;br /&gt;
::Sometimes the &amp;quot;savings&amp;quot; of storing data in a compact form are exceeded by the &amp;quot;cost&amp;quot; of having to convert it between the convenient-to-use form and the compact form.  I used to work on a system that used 32-bit words for all data types: characters, shorts, longs.  When we started running out of space, we &amp;quot;manually&amp;quot; packed our data, stuffing multiple shorts and bytes into words.  But in some cases, the additional code needed to pack/unpack would have taken more space than what we'd have saved in the data, without even looking at the processing time cost.

:The first computerised passport system for the UK had a y2K issue. In fact, it was designed in, because it was supposed to be replaced before 1999. Unfortunately, progress with its replacement was running late. We thought that we could get away with two digits for certain dates because the software was going to be thrown away before the end of 1999. And yes, two digit years were common in COBOL programs because decimal numbers coded using ASCII or EBCDIC were the default for numeric data.

&lt;br /&gt;
:1. Having done programming since 1966, I know that much data was stored on 80-character cards (and way before that year and the IBM System/360) and using 2 characters (2.5% of the card) to store the &amp;quot;19&amp;quot; was not acceptable. As processes moved into the tape and disk world, human nature tended to not expand the field to 4 characters (the future is a long way off until, suddenly, it isn't).

&lt;br /&gt;
:2. I actually saw a Y2K failure.  It occurred at the beginning of 1999 when a job scheduling program scheduled a job for the year 1900 because it was always keeping the schedule active a year in advance.  The scheduling software had actually been fixed but the upgraded version had not been installed yet, so there was no significant outage.

I/we always assumed the 19 was hard-coded, the 1-99 was a script, just concatenated.

: Back when The Matrix first came out, there was an unaffiliated website called www[dot]thematrix[dot]com (the movie used &amp;quot;whatisthematrix&amp;quot;), where the front page included a complaint that nobody from the movie even tried to buy his domain, nobody warned him, it didn't seem to occur to anybody that people would instinctively type in HIS address, and now he was flooded with visitors looking for the movie. Only other thing I remember about the site was that he had a menu CUBE. You slide the mouse over it to spin it - in literally any direction - each side had a single letter that when clicked brings you to a different page on the site. Fantastic piece of graphical scripting (PLUS functional as a click-able menu!), full 3-dimensional graphical animation... I also remember some note about &amp;quot;Don't ask for the code for the menu cube, just program things yourself&amp;quot;. :) That Rubik's Cube made me think of it. I would imagine having ALL sides being buttons could be a problem (how do you put it down?), but I could imagine it being functional... 6 sides, 9 keys, so 54 keys... Alphabet is 26, numbers is 10, shift and caps lock and enter and backspace makes 40 keys, that leaves 14 keys left to cover symbols (with shift being able to double up assignments), IDK seems pretty workable. :)&lt;br /&gt;

: Configuring in this case would mean putting the keys in a certain arrangement. I.E., putting the keys that you are most likely to use in a convenient place relative to each other.

Implementing SerifLock via CapsLock is made further difficult because it keeps state and doesn't generate a character, which can be problematic. Also, many applications load and track fonts on their own - making a key-mapping an application-by-application affair.  (Im)Practically for Windows users, Microsoft deprecated Application.OnKey in Word (but not in Excel) *and* the KeyBindings approach leaves out Caps Lock, requiring a low-level keyboard hook to try to accomplish this.  This is unfortunately bizarrely difficult to just tack in, but would be awesomely useful for those who don't mind coding their favorite serif font to an otherwise unused key...

Isn't the spacebar more accurately described as vertical, not diagonal? [[Special:Contributions/162.158.79.191|162.158.79.191]] 06:49, 29 May 2019 (UTC)&lt;br /&gt;

The retards who write this don't know what above, below, top, bottom, and vertically mean.  There are no keys on the bottom of a real keyboard.  And travel has nothing to do with keys but fare or stroke does.  Serif lock could refer to the section of Unicode with serifed alfabet.

:This is a wiki. You are free to improve the text if you feel that some terms are wrong, or by adding an alternative interpretation of e.g. serif lock. However you decided to instead spend your time on calling people retards, in hope that they will take your (partially deserved) critism and improve it instead. In my experience that is not a typical reaction of insulted people. --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 11:59, 24 July 2019 (UTC)&lt;br /&gt;

Why is 'Barack Obama is 6'1&amp;quot;' and 'Barack Obama has 4 legs' medium precision? It seems to give exact value, so high precision. [[User:Tkopec|Tkopec]] ([[User talk:Tkopec|talk]]) 11:44, 9 November 2022 (UTC)&lt;br /&gt;
: OK, I get it. 6'1&amp;quot; means something between 6'0.50&amp;quot; and 6'1.49&amp;quot;. For height it's OK, but when counting legs, it seems like a stretch. [[User:Tkopec|Tkopec]] ([[User talk:Tkopec|talk]]) 12:30, 9 November 2022 (UTC)&lt;br /&gt;
:: The four legs are probably considered to be only medium precise, not because of the number but because of the imprecise term &amp;quot;leg&amp;quot;. While humans can walk on all four extremities, thereby using them as legs, the upper two are commonly referred to as arms. [[User:Bischoff|Bischoff]] ([[User talk:Bischoff|talk]]) 14:54, 9 November 2022 (UTC)&lt;br /&gt;
:: (ECed by Bischoff) Plus a person's height (excluding differences to footwear and perhaps hairstyle) varies by an inch or so over the course of a day, as the spine compresses whilst mostly upright (would depend a bit upon your daily activities, but &amp;quot;an inch&amp;quot; or 2-3cm is the typical quoted value, with all the questions about precision ''as well as'' accuracy). Within an inch of such a foot-and-inch value is basically between slightly over a percentage point of drift across a continuum of ultimately non-integer values.&lt;br /&gt;
:: The number of legs is ''generally'' a whole number (perhaps lower-limb amputees could claim &amp;quot;half a leg&amp;quot;, but is that for above the knee or below or... that's beyond my wish to define, I would leave it up to the individual amputee to finesse to their own liking) and assigning decimals, even .000(recurring), would be ''over-''precise. A definite plain figure (however inaccurate) being the happy and acceptable medium between that and the vague imprecision (never mind inaccuracy) of the kind in the cell below.

==Explanation==&lt;br /&gt;
{{incomplete|Created by an EXPLANATION SEED. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
[[Beret Guy]] seems to be using {{w|volcano}} seeds to grow tiny volcanoes as an alternative to fertilizing [[Cueball]]'s garden. In reality, volcanoes are caused by the pressure of {{w|magma}} (underground lava) from below the Earth's crust pushing up through it, not seeds.&lt;br /&gt;
&lt;br /&gt;
Volcanic soil is [https://www.sciencedirect.com/topics/earth-and-planetary-sciences/volcanic-soil generally fertile], although as Cueball points out, the process of eruption is destructive to whatever plants are ''presently'' in his garden. Beret Guy's announcement in the final panel resembles the voice-over from nature documentaries.&lt;br /&gt;
&lt;br /&gt;
The title text alludes to the fact that sulfate {{w|aerosol}}s from volcanic eruptions may cause a [https://www.sciencedirect.com/topics/earth-and-planetary-sciences/volcanic-soil short-term cooling effect], expanding on the comedy from a small scale volcano, by adding small scale volcano effects — in reality, the cooling effect occurs because the {{w|aerosol}}s in the atmosphere block out energy from the sun.&lt;br /&gt;

:[Cueball is standing, holding a trowel. Beret Guy is kneeling, and pouring the content of a small bag in a hole in the ground.]&lt;br /&gt;
:Cueball: Thanks for the gardening help!&lt;br /&gt;
:Beret Guy: I made these seeds myself!&lt;br /&gt;
&lt;br /&gt;
:[Beret Guy is standing next to a small eruption coming from the ground.]&lt;br /&gt;
&lt;br /&gt;
:[Same scene, eruption is now a knee-high volcano. It produces fumes.]&lt;br /&gt;
:Beret Guy: The infusion of nutrient-rich volcanic soil will revitalize your garden.&lt;br /&gt;
&lt;br /&gt;
:[Same scene, the volcano is now waist-high. There are flames on its sides.]&lt;br /&gt;
:Cueball (as an off-panel voice): All my plants are on fire.&lt;br /&gt;
:Beret Guy: But soon, life will return to these slopes!&lt;br /&gt;
