Editing Talk:1180: Virus Venn Diagram

If nothing else, defragging the Singularity would keep it busy for a few hours. ~ [[User:Quackslikeaduck|Quackslikeaduck]] ([[User talk:Quackslikeaduck|talk]]) 13:40, 1 March 2013 (UTC)

I wonder if defragging the Singularity would actually erase/ruin it. Just imagine what would have happened to the first multi-cellular organism if someone had rearranged its molecules in what it considered to be a more "efficient" manner!--[[User:Joehammer79|Joehammer79]] ([[User talk:Joehammer79|talk]]) 15:00, 1 March 2013 (UTC)

And for a minute I was asking myself what black holes had to do with it... --[[Special:Contributions/65.222.165.65|65.222.165.65]] 16:14, 1 March 2013 (UTC)

: Well, beyond borrowing the name from the black-hole concept, there's something else too. You could say defragging decreases entropy. Decreasing the entropy of a black-hole would lead to what? Not a black hole? Bear in mind that black holes are tricky from a physics POV, and to top that, entropy, in the context of gravitation is a tricky thing. Also, the entire concept of "efficiency" is governed by the second law. So... Damn. I've tied this into all sorts of knots. But I'm going to say, if you tried defragging the singularity, it would actually prevent it from acting (since any action increases entropy), and therefore, IS a viable method to slow down the AI takeover.

I've managed to put someone in the "Maybe it has a Virus" category.  I added an implementation of "{{w|Neko_(computer_program)|neko}}" to an application we where working on, and the little cat following the mouse just confused a user who had never seen it before.

It's actually an Euler diagram, not a Venn diagram. --[[Special:Contributions/23.17.150.29|23.17.150.29]] 21:04, 1 March 2013 (UTC)
:I looked it up and agree. I wonder if someone has told Randall. I know he would appreciate it ([[1053: Ten Thousand]]). I'm not sure whether or not to change the "a Euler diagram" to "an Euler diagram" though. --[[User:DanB|DanB]] ([[User talk:DanB|talk]]) 21:31, 1 March 2013 (UTC)

:Actually, this IS a Venn Diagram, not an Euler diagram.  In an Euler diagram, one thins is a subset of another, which in this case would suggest that either all suspected cases of computer viruses are a subset of actual computer viruses, or the reverse, which I really don't think Randall is trying to imply, or rather NOT imply by his joke.  For one thing, the joke is that problems that are caused by computer viruses and problems that people suspect are caused by computer viruses should have some overlap, but don't.  This does not fit with an Euler interpretation of the graph as that would say (if one of the circles was inside the other) that every time the problem is a computer virus, people always correctly identify them but also assume other non-computer virus problems are viruses - or the reverse - all problems are caused by a computer virus but only a few are identified as computer viruses. Secondly, and more importantly, in an Euler diagram one circle is always SMALLER than the other, where as in a Venn diagram they are always the SAME size.  Oh, and last but not least, I'd be very surprised if Randall didn't know the difference between a Venn and an Euler diagram, since I'm sure he's had to use both many times.--[[User:7OO Tnega Terces|7OO Tnega Terces]] ([[User talk:7OO Tnega Terces|talk]]) 07:43, 3 March 2013 (UTC)
::I'm citing Wikipedia: "Euler diagrams consist of simple closed curves (usually circles) in the plane that depict sets. The sizes or shapes of the curves are not important: the significance of the diagram is in how they overlap." I didn't know about this before, but I learned it because of DanB's cunning. No one knows everything, not even Mr. Munroe, and I'm sure you can use both kinds of diagrams many times without knowing their definitions.

:I'm not so sure whether this really is a standard Venn diagram. According to quite some sources ([1] https://en.wikipedia.org/wiki/Venn_diagram, section "Overview"; as well as these papers: [2] [http://arxiv.org/abs/1207.6452 arXiv:1207.6452], [3] [http://arxiv.org/abs/math/0603068 arXiv:math/0603068], have a look at p. 1 and pp. 1/2 respectively, also: [4] [http://arxiv.org/abs/cs/0512001 arXiv:cs/0512001], Wolfram MathWold agrees: [5] http://mathworld.wolfram.com/VennDiagram.html), a Venn diagram is "[...] a set of n [– in this case 2 – ...] closed curves [– circles –] that subdivide the plane into 2^n connected regions [...]." [3, p. 1]. So we would actually expect to see 4 regions – in a standard Venn diagram. Obviously here the intersection is supposed to be empty (yielding only three regions), making this effectively an Euler diagram, in which circles are allowed to be the same size -- why should they not (https://en.wikipedia.org/wiki/File:Hamilton_1881_example.jpg). Additionally, Euler diagrams are not only used to illustrate "(for all x) if A, then B" or "all A are B", but also "no A are B" etc. You might also want to have a look at this blogpost concerning Euler vs. Venn: [http://blog.stevemould.com/venn-vs-euler-diagrams/ Venn Vs Euler: The Diagrams]. As this comic is titled "Virus Venn Diagram" one expects to see a classical Venn diagram, one does, however, not get to see one, but rather an Euler diagram showing very drastically that there is no intersection of the set of problems that make one think there might be a virus causing it and the set of problems actually caused by a virus. That's my amount of unnecessary pedantry for today. [[Special:Contributions/89.182.242.115|89.182.242.115]] 12:19, 3 March 2013 (UTC)

-'''"Defragging" is [...] an easy, user-friendly action that PC users can undertake to supposedly make their computers run faster.'''
-Defragging rearranges the blocks of a file system to avoid skipping while reading. It's actually just for some file systems (on Linux it's done automatically) and it does make reading faster if you're using a hard drive as storage.

-:Every filesystem is possible to {{w|defragmentation|defragment}}. Difference is that some filesystems need it more that others. Specifically, {{w|File Allocation Table|FAT}}-based filesystems needs it a lot, while filesystems like Linux's {{w|ext2}}, {{w|ext3}} ... are allocating blocks in a way which supposedly lowers the need of defragmentation. Anyway, the main reason why Linux filesystems are not being defragmented is that there is no application for that. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 11:32, 21 November 2013 (UTC)

-:::SSDs don't have the same (sort of) performance penalties from having fragments of files scattered all across the 'logical' drive-space as a platter-drive (that needs the read/write head to move in and out to catch the right cylinders of disk and await the right sectors to spin past). And, more than that, the 'physical' drive-space may not even be contiguous for any 'logical' address, for reasons of read/write operations needing balancing across the circuitry and any failing/failed bits of disk-memory being made arbitrarily unusable in favour of some spare space elsewhere.
-:::And if you ''do'' shuffle this data around in an apparently more ordered manner, it'll probably not improve the (already fast) access time but it'll risk introducing access errors just a little bit every time you do it. (Certainly, this used to be a problem... I don't know if it's still as bad, but they put a lot of development time into error-tolerant operation in order to counter the issues.) It definitely was unnecessary/discouraged to defrag SSDs back in 2014, and I can't see it have changed much since I stopped being so pplrofessionally interested in such things.
