Bitcoin

My understanding of bitcoins and blockchains is that each new "transaction"(?) requires some new information plus an encrypted version of all of the information it is "transacting" (is that a word?). Therefore the blockchain files are presumably getting bigger and bigger. So my questions are, how large was the original bitcoin file and how large are bitcoins now? -- SGBailey (talk) 06:09, 14 May 2025 (UTC)[reply]

This website has a nice graph showing that it started very tiny and is now around 640GB. 68.187.174.155 (talk) 10:32, 16 May 2025 (UTC)[reply]

If that graph is accurate, the growth has come to a sudden virtual standstill as of 1 May 2025. Extrapolation of the growth from February 2023 to April 2025 would have led one to have expected as of now a number close to 750GB. ‑‑Lambiam 21:39, 16 May 2025 (UTC)[reply]

Why did Reddit shadow-suspend my account and remove every last comment and post I've ever made on it, just for making 7 cross-posts of the same topic?

Inappropriate questions for the reference desk, also unrelated to computing,

The following discussion has been closed by Lambiam. Please do not modify it.

Now that my username there cannot be used anymore, it was u/TheresJustNoMoney. I don't mind sharing my username elsewhere like here now, for that very reason.

THE CROSSPOSTED TOPIC:

To all you Nordic guys named Sven: If your name can be Sven, then can my name be Eght?

Is Eght a valid name anywhere in the world much like how Sven is in the Nordics?

What if I made Eght my nickname only for when I'm around guys named Sven?

Where and in which countries is Eght a normal given name? To all of you named Sven: If you met a guy *actually* named Eght, what would your reactions be like?

S(e)ven crossposts, in order to keep up with the Seven / 7 / Sven theme:

r/NameNerds: r/namenerds/s/gDLfQYlJpU
r/NordicCountries: r/Nordiccountries/s/6Ut24lbU6v
r/Norway: r/Norway/s/23FiXcvjiI
r/Sweden: r/sweden/s/VPYE1ognh7
r/Unket: (A technical difficulty kept me from posting there.)
r/Finland: r/Finland/s/3LOvuBrKYo
r/Denmark: r/Denmark/s/tDMecViB3J

So why also remove all comments, posts and contributions I've EVER made to Reddit under that account when suspending it? Even the good, high-Karma ones? Why not preserve all but the problem submissions?

GNU/Linux

I want to make a fully-free copy of Tiny Core GNU/Linux whilst developing my own kernel. Should I use busybox? Gnu779 ( talk) 14:22, 18 May 2025 (UTC)[reply]

Are you prepared to provide the same APIs for BusyBox to talk to your kernel as the GNU Linux kernel does? Then it will probably save you some development effort. ‑‑Lambiam 20:34, 18 May 2025 (UTC)[reply]

No, I'm building fully free TinyCore first.

KSP Libre Version

I'm writing a libre version of KSP, licensed under GPL 3 for GNU/Linux platforms. Where can I get 3D assets of KSP vehicle parts because I will write in OpenGL MESA in C? Gnu779 ( talk) 14:25, 18 May 2025 (UTC)[reply]

Don't say about copyrighted stuff, because I don't want to talk about legal info.

Gnu779 ( talk) 14:27, 18 May 2025 (UTC)[reply]

If you don't want to talk about copyright, what's the purpose of developing libre software? Aaron Liu (talk) 18:26, 18 May 2025 (UTC)[reply]

Perhaps to make it available to users? ‑‑Lambiam 20:26, 18 May 2025 (UTC)[reply]

Why not just redistribute copies of KSP then? Aaron Liu (talk) 21:37, 18 May 2025 (UTC)[reply]

Is it me? I assume "KSP" in this question is the initialism of Keyword Services Platform, but for the rest I don't understand the question. What are "KSP vehicle parts"? What are "3D assets of vehicle parts"? Why are they needed for providing information about keywords used in search engine queries? ‑‑Lambiam 20:25, 18 May 2025 (UTC)[reply]

When you are being sued, as you will be, it will not help that you don't want to talk about legal info. ‑‑Lambiam 09:10, 19 May 2025 (UTC)[reply]

What is the computational power Q of the world's best N=16-Rechenwerk device?

What is the computational power Q of the world's best N=16-Rechenwerk device? For the meaning of the word "N=16-Rechenwerk", please see German Wikipedia de:Wikipedia:Auskunft/Archiv/2025/Woche_19#Für_eine_gegebene_natürliche_Zahl_N:_Wie_nennt_man_ein_technisches_Gerät,_das_die_in_dieser_Frage_beschriebene_mathematische_Funktion_möglichst_effizient_berechnen_kann?! 2003:ED:B722:800:B46D:A520:F44C:58CF (talk) 11:49, 22 May 2025 (UTC)[reply]

Edited a link. --CiaPan (talk) 11:52, 22 May 2025 (UTC)[reply]

Hard to tell, because the speed of supercomputers like El Capitan is typically given in FLOPS, which is not relevant here. In one step there seem to be two fetches and a store. They are mostly of consecutive locations, so a pipeline architecture will accelerate that, but I think memory access will be the bottleneck; much of the arithmetic can be implemented efficiently as bitwise operations. It looks that with some analysis the computation process can also be parallelized. On a single core, one step may take maybe 10 ns, so 10 million cores can do perhaps 10¹⁵ steps per second. For the about 10⁶ steps needed for N = 16, this would then take one nanosecond. Note that this is at best a ballpark figure; it may be off by orders of magnitude. ‑‑Lambiam 16:57, 23 May 2025 (UTC)[reply]

Just my concern about Analytic geometry

block evasion

The following discussion has been closed. Please do not modify it.

This picture in this article Analytic geometry#/media/File:Stereographic projection in 3D.svg can be changed to this rather, https://drive.google.com/file/d/11LIxCSDGHHScIrgrJOX-6MfiDE4nS6D4/view?usp=sharing. Unfortunately, that cannot be done as I've said, as the picture I'm referring is from the cine world, I mean the cinema as because

Concerning analytic geometry I think this topic which was added earlier - https://en.wikipedia.org/w/index.php?title=Talk%3AAnalytic_geometry&diff=712799894&oldid=712292654 is somewhat relevant in this Talk:Analytic_geometry which was closed and got removed from the Talk Page. He'd gone little outrageous and he made his addition to this talk page which is gibberish, so it got removed. However by Conic Sections we cannot intrude our own world, as, coz, because it is just in 2D. First of all 3D is different. Prior to make our own assumptions on String Theory, we must speculate clearly as because Conic Sections and this analytic geometry sees things that is in / on only in 2D aspect as we know, so it is very dangerous if at all if it is applied to 3D object, clear analysis and clear speculation is very much required before we approach

Editorial team please accord by so and make necessary edits in this Article - Analytic Geometry.

Is there a question here? Wikipedia has no editorial team. See Wikipedia:About. The image in the article is that of the infobox Template:General geometry, found on many articles on geometric topics, Absolute geometry, Bernhard Riemann, Circumference, ..., Zero-dimensional space. In no way is it meant to be specific to analytic geometry – although analytic geometry is a useful tool for working out the equations of the stereographic projection. ‑‑Lambiam 16:32, 23 May 2025 (UTC)[reply]

Then I suggest that the image doesn't belong in that template, as it misleads the reader into thinking that it's relevant to the specific geometrical topic. In fact, based that's not an infobox, it's a navbox that's being placed like an infobox. (Opinion ends.) --142.112.140.58 (talk) 23:29, 24 May 2025 (UTC)[reply]

Re: Fandom

The WP article states that Jimmy Wales (who everyone already knows co-founded the platform we're on now) remained on this farm's staff as late as 2018. Per Fandom's own About page, just wanted to make sure if he's still with them in the current TPG era. (H/T this overview at Shout's Anti-Wikia Alliance [AWA].)
