For every fave this tweet gets, I will give you one #golang fun fact
Fact #1: according to the go spec, build tools should resolve imports in alphabetical order in order to ensure initialization remains the sa
Fact #2: -128/-1=-128 in #golang, but only sometimes.
Fact #3: identifiers are only exported if they’re part of the Unicode uppercase class, which makes Unicode support basically irrelevant.
Fact #4: go doesn’t have a ‘xor’ operator for Boolean values, but it DOES have a ‘xor’ operator for... integers.
Fact #5: go functions can return multiple values, kind of like tuples except 40 times harder to work with.
Fact #6: in go, integer division is a Euclidean domain, except when the dividend is nonnegative and the divisor is a constant power of two.
Fact #7: Since go requires alphabetized package imports, ‘go fmt’ is sort of part of the build system.
Fact #8: integer overflows aren’t actually an error in go, but only when they arise from +,-,*, or <<
Fact #9: instead of algebras sum types, go has iotas in constant declarations, which are kind of just worse in every feasible way.
Fact #10: go doesn’t have generics
Fact #11: go’s error handling has been compared to shoving spaghetti up your nose with a salad fork.
Fact #12: numeric constants are not allowed to overflow; you can’t put ‘NaN’ in your code unless it’s at runtime and sufficiently unexpected
Fact #13: for some reason, “runes” (literally just Unicode code points) are considered numeric constants too. God fucking knows why.
Fact #14: much like Haskell, go makes the mistake of treating code points as units of text. Unlike Haskell, it wasn’t created in 1998.
Fact #15: if you try to implement a library for recursion schemes in go, rob pike will burn your house down.
Fact #16: #golang has its own version of Goto statements, which means someone thought about this for more than two seconds AND STILL DID IT
Fact #17: Go’s package management is basically “github lol”, because apparently code points are numbers but versions aren’t.
Fact #18: if you change your github username, you break every package that depended on one of your packages (extra transition milestone!)
#19: channels are one of the better parts of #go, but debugging concurrent code for is about as fun as the theater when your name is Abraham
Fact 20: #golang is popular for web, probably because http was too easy and developers needed to worry about when dividing by two would work
#21: Rob pike is kind of like Jesus, if Jesus gave hungry people a programming language wisely crafted for their little poor person brains.
Fact #22: go, supremely elegant from its simplicity, kindly gives you a ‘&^=‘ operator.
Fact #23: 0010 is #Go for ‘eight’
Fact #24: ‘0xFace’ is #golang for ‘64206’
#25: during package initialization, the compiler doesn’t do real dependency analysis and instead pretends some orgy of strings is a solution
Fact #26: go depends on satan when computing arctangents golang.org/src/math/atan.…
Fact #27: go, in its infinite simplicity, kindly provides you with an isNaN() function, since ‘== NaN’ is too clear to be considered valid.
Fact #28: #golang’s math library has a function called J0, deftly designed to never be inscrutable to anyone who might steal you physics hw.
Fact #29: you can’t do Peano arithmetic on types in #golang, despite the fact that apparently ‘﷽’ is a numeric constant.
Fact #30: Rob Pike invented static binaries, because dynamic linking was too fast and CPUs needed a rest.
#31: if you’re tired of pl theory, try pl practice!! Go compiles to its own version of assembly and calls a bespoke assembler (2nd compiler)
#32: Go depends on approximately 6,000 environment variables at any given time.
#33: go’s compiler is extremely fast, giving you ample time to debug data races and deadlocks.
#34: go’s assembler can target IBM mainframes, in case you get sad that COBOL doesn’t have enough deadlocks.
#35: go has a library called ‘testing/quick’, which makes you think of ‘QuickCheck’, but not for very long because it’s just a fuzzer.
#36: go provides bit shifts for multiplication by two, in case you hear the phrase “premature optimization” and come.
These aren’t even facts anymore I’m just shitposting. But anyway,,,
#37: #golang is extremely close to the metal, which is especially appealing if you know nothing about how modern processors work.
Fact #38: go is supposedly a garbage collected language, but it has not once deleted itself nor any of my code.
Fact #39: Go has variadic functions, which are basically a way to avoid adding algebraic data types by swallowing a bomb.
Fact #40: for loops are basically maps/filters that suck their own dick and throw type safety out the window in the process.
#41: go is extremely good for reimplementing python tools and getting a nice speed boost while preserving all the runtime errors.
#42: the go community has a really cute webapp that generates a picture of you as a gopher and I’m jealous 😠😠
#43: go has ‘break’ statements, which are quite cleverly named: they will often break your code as well!
#44: Go can be transpiled to JavaScript, which is Satanic.
#45: array slices can take three different indices, much like literally any no other language in existence.
#46: relatedly, a slice containing three elements can have a capacity of four in case you need fine control of memory and also bugs.
#47: go has semicolons for some reason. Along with curly braces, they are what makes the language “fast”
#48: slices can have a lower, upper, and maximum index, but not a minimum index - just like the elegant simplicity of the Chinese board game
#49: James Damore probably wrote Go.
