First in linear time![[User:Mr. I|Mr. I]] ([[User talk:Mr. I|talk]]) 13:28, 18 December 2024 (UTC)

Due to the fact that O(nlog(n)) outgrows O(n), the Linear Sort is not actually linear. [[Special:Contributions/162.158.174.227|162.158.174.227]] 14:21, 18 December 2024 (UTC)

The title text would be more correct if Randall used e.g. Timsort instead of Mergesort. They both have the same worst-case complexity O(n*log(n)), but the former is linear if the list was already in order, so best-case complexity is O(n). Mergesort COULD also be implemented this way, but its standard version is never linear. [[User:Bebidek|Bebidek]] ([[User talk:Bebidek|talk]]) 16:35, 18 December 2024 (UTC)

: First, I don't recognize the language, but sleep() takes seconds for python, C (et. al.), and no doubt many others.

Of course, no coefficient is big enough for this to actually be linear in theory for any size list, so who cares? To be truly accurate, sleep for `e^LENGTH(LIST)`, and it really won't much matter what the units are, as long as they're big enough for `SLEEP(e)` to exceed the difference in the time it takes to sort two items versus one item.

If I had a nickel for every time I saw an O(n) sorting algorithm using "sleep"… But this one is actually different. The one I usually see feeds the to-be-sorted value into the sleep function, so it schedules "10" to be printed in 10 seconds, then schedules "3" to be printed in 3 seconds, etc., which would theoretically be linear time, if the sleep function was magic.

2950: Situation

2024-06-25T18:46:30Z

Jlearman: added "Galloping Gertie" nickname for Tacoma Narrows bridge.

==Explanation==
{{incomplete|Created by a Shark, the iceberg of the sea - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic depicts a situation involving multiple pieces of infrastructure: a ship, sailing towards icebergs, which is tethered to an airship flying next to a power plant towards a bridge. Each of these are labelled with details that clearly reference famous disasters, all of which were caused (at least in part) by design failures. All of these incidents are common case studies for engineers studying how things can go very wrong. The implication is that, by putting them all together, most engineers would be highly concerned with the potential for catastrophe.

;"Unsinkable Ocean Liner" refers to the RMS ''{{w|Titanic}}''.
:The ''Titanic'' was a British ocean liner which famously {{w|Sinking of the Titanic|sank}} on its maiden voyage in 1912. It was the largest ship in operation at the time, and was called "unsinkable" due to its size and much-lauded design features. The ship struck an iceberg on the fourth day of its first voyage, breaching the hull and ultimately causing it to sink, resulting in 1,496 deaths. Multiple design inadequacies (although none without precedent in contemporary vessels) were afterwards identified as contributing to the rapid speed of the ship sinking and to the high loss of life. These included: too few life boats; inadequate steering ability; compartments lacking watertight ceilings and therefore allowing the water levels within to top over into previously unaffected sections.

;"Hydrogen-filled [...] Airship [...]" refers to the {{w|Hindenburg Disaster}}.
:The {{w|LZ 129 Hindenburg|''Hindenburg''}} was a German airship which used hydrogen as a lifting gas. In 1937, during a landing in New Jersey, the ship caught fire and the flammable hydrogen quickly ignited, causing the ship to crash and resulting in 36 deaths. While the origins of the fire are still debated, the dangers of using large amounts of flammable gas in airships were made dramatically clear.
:Ironically, the airship in the comic appears to have been commissioned for the purpose of mitigating iceberg risks (unless 'iceberg spotting' is for the purpose of steering the 'Unsinkable Ocean Liner' towards icebergs, perhaps as a tourist attraction).

;"Soviet Era Nuclear Reactor Undergoing a Turbine Test" refers to the {{w|Chernobyl Disaster}}.
:The {{w|Chernobyl Nuclear Power Plant}} is located near the city of Pripyat, in Ukraine (part of the Soviet Union at the time of the disaster). On 26 April 1986, a reactor core partially melted during a turbine test. This led to an explosion, causing a massive release of radiation. This incident remains the worst nuclear accident to date. The cause of the disaster was determined to have resulted from a combination of uncommon circumstances and human error, which the reactor wasn't designed to account for.
:The number of fatalities from the disaster is difficult to calculate; two people died from the initial damage, twenty-eight more from acute radiation sickness, and fifteen people who were directly exposed developed terminal thyroid cancer. The radiation, however, spread far beyond the plant itself, and the number of premature deaths ultimately attributable to subsequent exposure can't be calculated directly, though most estimates are easily in the thousands.

;"Bridge Prone to Aeroelastic Flutter in High Winds" refers to the {{w|Tacoma Narrows Bridge (1940)|Tacoma Narrows Bridge}}.
:The Tacoma Narrows Bridge, a suspension bridge in the U.S. state of Washington, was initially built in 1940. From the time of its construction, the bridge was observed to sway and {{w|Aeroelasticity#Flutter|flutter}} in high winds, and was nicknamed "Galloping Gertie". About four months after opening, in 40 mile-per-hour (64 km/h) winds, the bridge fluttered so violently that it collapsed into the strait. There were no human fatalities, though several people were injured. This collapse is frequently used to demonstrate the dangers of harmonic vibration in infrastructure, particularly structures exposed to strong winds. The bridge was eventually rebuilt, with a redesign intended to prevent such fluttering.

;The title text refers to the {{w|Space Shuttle Challenger Disaster}}.
:The {{w|Space Shuttle Challenger|''Challenger''}} was an American space shuttle which broke up shortly after its launch in 1986, killing all seven crew members aboard before reaching orbit. The disaster was caused by a failure of O-ring seals on one of the shuttle's rocket boosters and the subsequent leak of hot gases. The likely cause of these failures was the seals being unable to maintain their integrity due to being well below their design temperature range in the immediate lead-up to being exposed to launch conditions, thanks to much colder than normal weather in the launch area. Engineers for the company that had built the boosters raised this concern and recommended postponing the launch, but were overruled.

As illustrated, it appears that the ship is about to sail under the bridge, while the airship will fly over it, causing the tether between the two to snag the bridge unless the airship descends sufficiently before then. It is not clear how or if the reactor will contribute to the resulting incident.

2891: Log Cabin

2024-02-08T13:36:26Z

Jlearman: /* Explanation */ replaced "some sort of storage area" with "closet," as this could be a linen closet, utility closet, or pantry, and the general term "closet" applies in all cases.

[[File:log_cabin_golden_spiral.png|thumb|301px|Golden spiral (approximately) overlaid on the floor plan]]

This is a comic featuring a {{w|floor plan}}, presumably of a {{w|log cabin}}, and a pun on the word "log". The odd part about it is the right half, which appears to be infinitely recursive copies of the building, a self-similar {{w|fractal}}. The house as a whole represents a {{w|golden rectangle}} with a side ratio of the {{w|golden ratio}} (phi = 0.5 + (1.25 ^ 0.5) ≈ 1.6180339887...), with successively smaller living areas (further subdivided into rooms, to a common but shrunken and rotated plan) being square adjoined by a golden-rectangle of all smaller living areas in the manner of the areas defined by the classic {{w|Golden spiral}} diagram. The joke is that Randall is intentionally conflating the word "log" in the common phrase "log cabin," where "log" refers to the wood the cabin is made of, with a {{w|logarithmic spiral}}, as "log" is shorthand for "logarithm".

Every square subunit of the premises consists of a main combined kitchen/lounge area, with an adjoining shower-equipped bathroom, and a hallway leading to a closet and two bedrooms (a double-bed one with en-suite bath-equipped bathroom, and another with a single bed; both having suitable walk-in closet space). Between the kitchen and the dining table is the door that serves as the entry into the next inwards level of the floorplan.

A visitor can also walk in a spiral by using the doors in the building plan.

In the title text, Randall says that he is confident that building inspectors will approve the design of his log cabin, assuming they can escape. As one moves deeper into the infinite spiral of architecture, the entire log cabin ''seems'' to be a denser labyrinth of rooms and hallways.

It is unknown how the inspectors lost in the inner rooms would shrink in the same ratio, and would only have to head out through the last door they walked in through (or two, if they're currently in the en-suite) and then exit each 'main' area in turn until they exited the building itself. If they have any trouble at all (other than rescaling themselves), it would be that there is ''always'' a further inward area that they might consider needs exploring to fulfil their inspection routine.

In any case, though, they would not need to physically enter the floorplan in order to approve the ''design'', so any risk of getting 'lost' would come solely from a psychological inability to break off from the infinite recursion. Approval of ''construction'' would be a different matter. Whether the floorplan could genuinely be infinitely recursive would depend on how Randall has presented it. Typically, these would be submitted as static images (as it is in the comic), in which case at some point there would be insufficient resolution to continue the recursion, effectively ending in a solid pillar. Randall, however, perhaps channeling his inner Black Hat, may have used a program that dynamically generates further levels as you zoom in to the image.

Alternatively, this may imply that the repetition continues outside of what is drawn here, continuing to grow larger as it moves further out. However, the apparent presence of external windows on the first four iterations, but no internal ones (and therefore no equivalent windows on the subsequent iterations) somewhat belies that possibility. In fact, the first iteration has windows on the 'southern' edge, for the single bedroom and seating area, for which there are no equivalents on any of the other iterations.

[https://www.generations-quilt-patterns.com/log-cabin-quilt-block.html Log Cabin] is also a classic quilting block, which starts with a tiny square and spirals outwards.

Talk:2880: Sheet Bend

2024-01-13T17:44:57Z

Jlearman: A sail isn't called a "sheet"

Why is this called a "sheet" bend? [[User:SystemParadox|SystemParadox]] ([[User talk:SystemParadox|talk]]) 21:17, 12 January 2024 (UTC)
:I don't know the full answer but it's a sailing thing: the 'sheet' is the rope you pull in or let out to control the position of the sail. I guess bend describes the category of knot. [[Special:Contributions/172.70.90.48|172.70.90.48]] 21:23, 12 January 2024 (UTC)
::NO NO NO. The sheet is the sail. [[User:JohnB|JohnB]] ([[User talk:JohnB|talk]]) 21:36, 12 January 2024 (UTC)
:::It is the rope - {{w|Sheet (sailing)}}. "In sailing, a sheet is a line (rope, cable or chain) used to control the movable corner(s) (clews) of a sail." [[Special:Contributions/172.71.242.5|172.71.242.5]] 21:56, 12 January 2024 (UTC)
::::Huh. Dueling Wikipedia articles. The Sheet_bend article has a definition section that says the term "sheet bend" derives from its use bending ropes to sails (sheets). But the Sheet_(sailing) article says a sheet is a line used to control the movable corner(s) of a sail. [[User:JohnB|JohnB]] ([[User talk:JohnB|talk]]) 23:08, 12 January 2024 (UTC)
::The sheet bend is named for its ability to to secure a sail, or sheet. You fold over the corner of the sail and that's one of your "ropes". The sheet bend is generally used as a knot for tying a large, inflexible rope (or rope-like object) to a smaller, more flexible rope.[[Special:Contributions/172.69.70.22|172.69.70.22]] 22:30, 12 January 2024 (UTC)
::I would take the Ashley Book of Knots as authoritative. Sheet Bend is the first knot in the book, and is always (in modern terms) rope-to-rope, not to sail. It is one of the basic knots. https://en.wikipedia.org/wiki/The_Ashley_Book_of_Knots https://en.wikipedia.org/wiki/Sheet_bend
::{{unsigned|PRR|04:04, 13 January 2024}} 
:I added a link to the wikipedia entry, it explains the name. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 21:25, 12 January 2024 (UTC)
:Presumably the "different loads" title text is a pun between electrical load and mechanical stress on the knot? [[User:Jim-at-home|Jim-at-home]] ([[User talk:Jim-at-home|talk]]) 21:56, 12 January 2024 (UTC)

A sail is never, and was never, properly called a "sheet", since at least the 13th century. The Wikipedia explanation of the name is misleading. According to https://www.etymonline.com/word/sheet, it's "shortened from Old English sceatline "sheet-line," from sceata "lower part of sail," originally "piece of cloth," from same Proto-Germanic source as sheet (n.1)." [[User:Jlearman|Jlearman]] ([[User talk:Jlearman|talk]]) 17:44, 13 January 2024 (UTC)

“silver being joined to silver and gold being joined to gold within the insulating white cable” is not the conventional way to join cables.
Unless you are joining one cable to itself (like a Möbius strip), you have ''two'' cables with insulation.
And usually you use non-cursed connectors, where you first remove the insulation at the end of the cable and then crimp or solder the conductors to metal parts of the connector; or solder the conductors and then add a different type of insulation for protection; or use screw terminals;...
Only with insulation displacement connectors you keep using all the insulation of the two cables.
And finally, conductors are usually copper ''or'' aluminum, and very rarely silver ''and'' gold. --[[Special:Contributions/162.158.94.141|162.158.94.141]] 08:45, 13 January 2024 (UTC)
:I think the gold and silver is just color coded for the reader. Not that they are meant to indicate that the conductors are made from this material. Apart from that you comment sounds like you know what you are talking about. So please improve the explanation if you can. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 10:58, 13 January 2024 (UTC)

Okay I looked at the wikipedia article and the knot depicted in the comic looks like a right handed one. I still don't know why it's called right handed, or why the left handed one is insecure.[[Special:Contributions/198.41.236.207|198.41.236.207]] 11:46, 13 January 2024 (UTC)

A note I nearly added in the bit about short-circuits (or, as I added, 'un'circuiting) is that the electrical behaviour of the knot is different according to which 'end' slips. If the left-side cable 'slips through' enough, then its gold and silver bits of sheath could contact (would short-circuit any current driven at that side). If the right-side cable slips out, it is in no danger of doing so for a right-driven current (it would just disconnect). That ignores the cross-talking that could occur (on one conducting line at a time, so may not matter if there's no external ground-return element, except as far as not being a proper connection any more), or ''both'' ends slipping (where one of the LHS sheaths ''might'' shuffle into a position to bridge the two RHS sheaths). But, as tied, the LHS silver (being bent in and out of the page around its crossing counterpart wire) seems unlikely to be pressed against both gold and silver, should it trivially untwine/slip through. Actual studies with actual knots might be useful. I thought I had a spare length of unterminated Cat5, nearby, but apparently (k)not... that, with some coloured permanent marker-pen marks made upon it, would probably have made a decent analogue for visual analysis of failure conditions. Maybe I'll de-plug an old cable (I've got a number of damaged USB cables I could chop, but their being thinner would change the scale and dynamics of the knot, meaning I might as well just use a scrap of twisted-pair internally-sheathed strands). – But I thought you'd like my mind's-eye analysis of the knot behaviour, before I get around to trying anything practical to this end.

NOTE: I'm assuming the IE/VE ligature is IE, where the I is tilted
Could this also be a reference to the historical Latin pronunciation of Æ, and its separation into "AA" (which could be represented by "ar" in English ("r" is silent), hence the ligature "AR") and "IE" (which would be pronounced "ee" as in "relieve") [[User:1844161|1844161]] ([[User talk:1844161|talk]]) 15:21, 14 April 2023 (UTC)

I think it might be helpful to readers to provide a parenthetical describing the pronunciation of the 'ash' glyph, so that people who aren't old language aficionados aren't left in the lurch if they're the sort who read aloud in their head. I'm going to add it, but if someone removes it I won't be miffed. Also, there's no way the new E ligature is meant to be IE.

Then we get EV as Eve.
Not yet sure where AR refers to, Adam and Romeo, Augmented Reality?
Love does contain VE as reverse of EV.
