Python: some people say "piton", some people say "paiton", some say "paizon".  
JSON: some people say "yeison", some people say "jota son".  
Java: some people say "java". Well, everybody I know, actually.  

Now, I guess that there might be a rule about how to pronounce these names. BUT, I'm of the opinion that there's no point in speaking in a way that makes it harder for others to understand me. And I'm pretty sure that many many people would need a second take if I said that I worked with "yava".
So how should I pronounce foreign technical words in Spanish? Should I pronounce it following the rules of the original language, should I use Spanish pronunciation, or something in between?

The RAE describes several possible approaches of pronouncing and spelling terms imported from another language.

"Mantenimiento de la grafía original, pero con pronunciación a la española y acentuación gráfica según las reglas del español. [Por ejemplo] para el anglicismo airbag (pronunciado en inglés [érbag]) se propone la pronunciación [airbág], o para master, la grafía con tilde máster." (2.2.a) Se escribe en letra redonda.
In other words, leave the spelling as is, and don't use italics or quotation marks, and pronounce the word according to the phonetical rules of Spanish.  (Note, "airbag" does not sound the same as "érbag would."  Also note, it looks rather as though the RAE wrote a tilde in the word in brackets, airbág, even though it wasn't needed, to make things extra clear.)

following Spanish rules by a significant percentage of Spanish - speak citizenry. Examples (based on my own experience ): 

 C #: some multitude say " ce sarp ", some people read " ce sostenido " or " ce almohadilla ".  
 Python: some multitude say " piton ", some citizenry say " paiton ", some say " paizon ".  
 JSON: some multitude say " yeison ", some people pronounce " jota son ".  
 Java: some citizenry say " java ". Well, everybody I know, actually.  

 Now, I guess that there might be a rule about how to pronounce these name calling. BUT, I'm of the opinion that there's no point in speaking in a room that makes it harder for others to understand me. And I'm pretty certain that many many people would need a second take if I said that I worked with " yava ". 
 therefore how should I pronounce foreign technical words in Spanish? Should I pronounce it following the rules of the original language, should I use Spanish pronunciation, or something in between?
