The Labyrinth Architect Solves Everything

Description

A multi-panel medieval comic shows a king, a servant, a messenger, and a newly revealed monster, with the servant repeatedly proposing labyrinths for wildly inappropriate things. The visible dialogue reads: "Allow me to present you this enormous cheese", "Sire, I will build a labyrinth to house the cheese!", "No! The kitchen will do fine", "My master also sends his regards", "Sire! I will build a labyrinth to house the regards!", "What is it with you and this labyrinth?", "Labyrinths are awesome!", and finally "Sire! The queen has given birth to a monster!" The final silent reaction implies that the servant has finally found the one situation where a labyrinth might be useful. For software engineers, the comic maps cleanly to overzealous architecture: applying the same favorite pattern everywhere until reality accidentally supplies a valid use case.

What is (or was) special with C# that got it so popular? How is it different from Java?
1. @RiedleroD 4y
  
  mostly just lots of smaller improvements in language design ig. well and because Microsoft pushed it for quite some time
2. @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Its a mix of 3 languages if I remember correctly
3. @SamsonovAnton 4y
  
  Java had one dramatic disadvantage: it was not invented by Microsoft. C# got this deficiency fixed.
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Lol
  
  @feedable 4y
  
  ah, yes, nih
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  I stopped using Java as soon as I realized you don’t have decimal and that you have to import BigDecimal and it has no operators because operator overloading isnt suppirted
  
  @SamsonovAnton 4y
  
  Well, I don't remember about Decimal, but .Net did not have BigInteger until version 4.0, and still does not have BigUInteger.
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  What is biguinteger
  
  @SamsonovAnton 4y
  
  Like BigInteger, but without that ugly sign and signed-only semantics not needed for unsigned applications. BigInteger is more about regular, abstract math. Real-world apps, like cryptography, need BigUInteger instead, with pre-computations and other high performance stuff.
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Noice thx
  
  @RiedleroD 4y
  
  meanwhile python: not even sure which values are Decimals and which are regular bigints/floats
  
  @SamsonovAnton 4y
  
  Meanwhile JavaScript: not even sure which values are numbers and which are strings.
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Lol js be like: 0.1 + 0.2 == 0.3 true Also JS: 0.1 + 0.2 0.3000000…00004
  
  @RiedleroD 4y
  
  same in python, but it rounds the last few digits to not seem weird
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Looool thats even more evil when debugging
  
  @RiedleroD 4y
  
  not really… it only does that when printing directly ig and float comparison has some weird rules too (you shouldn't be doing that anyway)
  
  @feedable 4y
  
  that's not js's fault
  
  @feedable 4y
  
  it is like that in every language
  
  @RiedleroD 4y
  
  yes, that's what I said. read a bit upwards
  
  @feedable 4y
  
  it's not unique to python too
  
  @RiedleroD 4y
  
  ye, but I said it's due to how float works - in general
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  null == 0 is false null > 0 is false null < 0 is false null >= 0 is true
  
  @RiedleroD 4y
  
  in python, null doesn't even exist. haha! but None does. 💀
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Looool
  
  @SamsonovAnton 4y
  
  Meanwhile Bash: not even sure which values are not strings (unless they are indexed arrays or associative arrays).
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Meanwhile asm: not even sure of what is value and what is instruction
  
  @SamsonovAnton 4y
  
  Not on every architecture. Some distinguish program space and data space, some have separate stacks for code and data.
  
  @RiedleroD 4y
  
  these architechtures famously suck for emulating because JITs have to work around that (at least on M1 macs afaik)
  
  @RiedleroD 4y
  
  depends if program space is read-only ig
  
  @feedable 4y
  
  why should you have a stack for code
  
  @SamsonovAnton 4y
  
  To be resistant to "arbitrary code execution by stack overflow" at least.
  
  @feedable 4y
  
  ooh, you mean shadow stacks
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Well yeah but it isnt that seperated either
  
  @SamsonovAnton 4y
  
  The address space is shared in this case, the stacks are not.
  
  @feedable 4y
  
  not necessarily
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  You still could end up at a spot where an old code was but its not there anymore
  
  @SamsonovAnton 4y
  
  That would trigger an exception even on x86, I think. However, to be sure one cannot call an arbitrary address, or access arbitrary data by manually constructed pointer (byte-grained), or to use uninitialized data (word-grained), there are hardware-enforced protection technologies.
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Lol no
  
  @feedable 4y
  
  nx-bit is required
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  But you can’t declare that for evey single byte right?
  
  @feedable 4y
  
  you declare it for a page
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Yeah thats the problem
  
  @feedable 4y
  
  how is it a problem?
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Read above
  
  @feedable 4y
  
  just map your code as executable, and your heap and stack as non-executable
  
  @SamsonovAnton 4y
  
  If you mix code and data within a page, you are screwed anyway.
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Well instructions are followed by parameters
  
  @feedable 4y
  
  these are embedded within an instruction, and you really really should not overwrite them. it's not like you can do that, anyway
  
  @ZgGPuo8dZef58K6hxxGVj3Z2 4y
  
  Umm what about JIT?
  
  @feedable 4y
  
  you map that code as rwx, and then remap it as r-x
  
  @feedable 4y
  
  you can actually not remap it, if you trust your jit to produce valid code
  
  @SamsonovAnton 4y
  
  If you worry about passing control inside a variable-length instruction, then use an architecture with fixed-length instruction or EPIC / VLIW. 😁
  
  @feedable 4y
  
  epic does not have a fixed length
  
  @SamsonovAnton 4y
  
  But you cannot successfully jump into an instruction word, I suppose.
  
  @feedable 4y
  
  you can always do that regardless of the arch, if you have the permission to do so
  
  @SamsonovAnton 4y
  
  The instruction decoder will throw "An illegal instruction" exception upon seeing an arbitrary garbage, unless you are [un]lucky enough to hit a purely valid pattern.
  
  @feedable 4y
  
  that will occur only after the jump, the only thing that prevents you from doing the jump itself is mmu
  
  @feedable 4y
  
  and if you don't have that, nothing will prevent you from doing anything
4. @saniel42 4y
  
  - Has less stupid restrictions - Has "structs" and more memory control in general - Looks better - Has operator overloading

  @saniel42 4y
  
  I hope this supposed to be a joke
  
  Deleted Account 4y
  
  Yes, it is
5. @Turok1234 4y
  
  It's just satisfying to write tbh, also in small cities and any other country than USA you have two career options: .Net and JS. Choose wisely as they say
@SamsonovAnton 4y

In fact, BigInteger is internally implemented as BigUInteger + sign logic. (Well, in fact it is more complex than that, but the basic idea is similar.) Unfortunately, with opaque implementation, it is not possible to not use the things you don't need, nor to add advanced functions (operators), nor extract the values that system implementation computes but discards, returning only one of them. So rolling out your own math library (or using third-party one) instead of System.Numerics is the only way to overcome the basic design.
