One of the first times I witnessed SJWs at work was back in 2000. There was a guy that made a popular modification for a particular forum software. His modification was so popular almost every forum on the internet was using it at that point. A year or so after it became popular some SJW discovered that every other line in the source code was

>//I like pussy

He posted a thread about it which kicked off a huge flame war as people piled in. After a few days the guy that made the modification got so pissed off he took down all copies of it and refused to work on it anymore. No one ever made a proper replacement so to this day people are begging someone to port it to the latest version but everyone refuses to do the work out of respect for him.

This. Terry wrote the system SPECIFICALLY for newbies, why would he include comments that do anything other than explain what a given block of code does?

You'd think it'd be full of "ahaha cia nigger lol i ran over KKK sum nigger on 9/9/9", but no, that's not what Terry means.

"Fast inverse square root" for lighting.

>>940895

https://en.wikipedia.org/wiki/Fast_inverse_square_root

>Initial speculation pointed to John Carmack as the probable author of the code, but he demurred and suggested it was written by Terje Mathisen, an accomplished assembly programmer who had previously helped id Software with Quake optimization. Mathisen had written an implementation of a similar bit of code in the late 1990s, but the original authors proved to be much further back in the history of 3D computer graphics with Gary Tarolli's implementation for the SGI Indigo as a possible earliest known use. Rys Sommefeldt concluded that the original algorithm was devised by Greg Walsh at Ardent Computer in consultation with Cleve Moler, the creator of MATLAB.[21] Cleve Moler learned about this trick from code written by William Kahan and K.C. Ng at Berkeley around 1986[22] Jim Blinn also demonstrated a simple approximation of the inverse square root in a 1997 column for IEEE Computer Graphics and Applications.[23][24] Paul Kinney implemented a fast method for the FPS T Series computer[25] around 1986. The system included vector floating-point hardware which was not rich in integer operations. The floating-point values were floated to allow manipulation to create the initial approximation.

There's probably lots of forgotten magical numerical approximation hacks written in 80s scientific codes.

>>940911

>There's probably lots of forgotten magical numerical approximation hacks written in 80s scientific codes.

Do you know any other?

>>941173

Not that anon, but Linux uses approximations of dividing by 1,000,000 in the networking code in various places when calculating time deltas of things like ACK intervals to avoid having to emit a real DIV instruction. These shift/add/sub mixes to approximate MUL/DIV were very common in the '90s when those instructions were much more expensive. It surprises people that they're still there today, and bothers others that critical timing code is deliberately inaccurate. I forget where in the code, but if I run into it tomorrow I'll post one.

2) she gives so few fucks about it, that doesn't even bother about hiring normal social media writer, and not some kid who values trolling more than his job

>This is why more women should get into coding

The Dao - Intro

Lesson1: The hacker spirit is; in oneness. "You" don't exist, therefore "your" skills are not "yours".

They're gifts offered throught the many iterative and parallel incarnations of the spirit.

Lesson2: The hacker spirit knows no gender. Spirit knows no form and spirit knows no sides. It is the balance source of balance.

Lesson3: The hacker spirit imbudes all and is omnipotent.

Lesson4: The hacker spirit knows not bugs. If bugs, the flesh is week. One must meditate on the Dao.

Lesson5: The hacker spirit wastes not bits, nor cycles.

The hacker spirit of the programmer who wrote that Quake RSQRT poetry (people wrote theses about the magic constant) is still unidentified (even the known masters - Carmack, Abrash, Mathisen, Romero - wo made the code public remain ignorant of its origins).

Only an egoless master of the Dao could disolve their ego to let the infinite intelligence immaculately reflect through the work and live on forever in the memories of those who recognize an enlightened being's work.

That tweet is typical "girl code glitter" and the spirit behind it is no hacker spirit. It is full of disappointing pride and shows no class.

Reinventing the max(a, b) is no big deal. A little analysis:

if (a < b) return b;

else if (a > b && b < a)

return a;

Most non initiates care less about compilation. Code isn't written for people, it is written for a compiler which in turn produces machine code.

Compilers have a spark of hacker spirit doing magic on behalf of the non initiate's ignorance - dead code elimination, loop unrolling, cache blocking, expression simplification, branch prediction, ...

When a non initiate is initiated into what's behind the veil, the newl initiate is humbled by the Grace of the spirit.

The condition of the else statement above will obviously be reduced by the compiler to if (a > b) rather than if (a > b && b < a), the condition being always satisfied on both sides. The only acceptable implementation of such operation is the following.

#define max(a, b) ((a) > (b)) ? (a) : (b) //A bit of Lispiness for the preproc.

This typeless macro can span any type for which the operator > is valid and will be handled by the preprocessor which will cause an "inlining" of the expression over a function call. Of course, the compiler will optimize the expression according to your desires (-O1, -O2, -O3, ...). An optimized integer implementation could also be expressed as follows,using a XOR and a compare:

static inline int max(int x, int y) { return x ^ ((x ^ y) & -(x < y)); } //

or as follows, using subtractions and a shift:

static inline int max(int x, int y) { return x - ((x - y) & ((x - y) >> (sizeof(int) * 8 - 1))); }

How is that "Lispy" at all? You aren't using prefix notation and you are trying to evaluate a number like it's a function.

>>943415

Excess parentheses! (.)(.) ((.))((.)) (((.)(.)))

>>943371

You have to understand the audience here. The first 2-3 years of college are 100% general education for the masses with like one or two specialized classes sprinkled in there. This is for drooling retards who have NEVER used a word processor or spreadsheet in their entire lives. Specialization doesn't begin until MS or Ph.D, minimum.

>>943422

Lisps don't use an excess amount of parenthesis, but rather the perfect amount unlike what the C preprocessor practically requires.

There are also various references to idiots and morons, some external, some within Microsoft. The file private\ntos\rtl\heap.c, which dates from 1989, tells us

    // The specific idiot in this case is Office95, which likes

    // to free a random pointer when you start Word95 from a desktop

    // shortcut. 

The file private\ntos\w32\ntuser\kernel\swp.c from 11-Jul-1991 points at

    * for idiots like MS-Access 2.0 who SetWindowPos( SWP_BOZO

    * and blow away themselves on the shell, then lets

    * just ignore their plea to be removed from the tray

Morons also abound, as in this selection

    private\shell\browseui\itbar.cpp:

Microsoft programmers also take their duty to warn others seriously. There are over 4,000 references to "hacks", mostly warnings. These include

While surprisingly informal, there are limits to how far the programmers go. There are no derogatory references to Microsoft or Windows themselves. Bill Gates is never mentioned. There are no racist or homophobic slurs. I saw only one drug reference.

    private\shell\ext\tweakui\genthunk.c:

those are all still integers and have no decimal points..........................................

not so much a comment. when I was reverse engineering a pre-cracked dos game I examined how the previous person got around copy protection. basically instead of shorting a jmp he explicitly made a code cave, which was a hassle in those days, passed execution then had a password cracking function in there. it did a whole lot of nothing then always passed back 8 in ax which was used as an immediate jump to get past the fail state of the copy protection.

it blew my mind but it felt kind of comfy to be next to someone's earnest if retarded code so many years later.

>>944294

> Numerical Recipes in <insert language here> for more examples

There's numerical analysis and there's numerical analysis:

1) Using numerical algorithms to come to solutions to problems.

2) Analyzing the result for goodness, for some definition of good.

My understanding is that Numerical Recipes primarily does the former and little if any of the latter. The attached book is entirely about the latter.

It's iterating over a set of points and computing the distance between each point and some other point, which given variable names is likely the "center" of the set. This means that the absolute value call is useless and probably indicates that either an idiot wrote it, or there is a horrible bug somewhere.
