What is the appeal of weakly and dynamically typed languages? Posted: 01 Aug 2019 04:42 PM PDT I must be missing something because I don't understand why everyone loves languages like Python for being dynamically typed. I can't quite see the benefit besides something like having a var be false until set to having a real value. To me all I can see is that it introduces lots of errors because of a var being changed type before passing into a function. Wouldn't you just need lots of extra checks for each function because of this? ELI5 maybe? submitted by /u/WackoDesperado2055 [link] [comments]

How are cookies and sessions used in services like Facebook and Twitter Posted: 01 Aug 2019 01:32 PM PDT I've been developing node.js backend applications for sometime now and I really dont know how cookies and sessions are really used. Could some give an example of how such would be used in services like Facebook and Twitter? submitted by /u/antgha [link] [comments]

CFG for PDF specification? Posted: 01 Aug 2019 12:45 PM PDT Would it be possible to create a context-free grammar for the PDF specification, and then generate a PDF parser using something like lex/yacc or flex/bison? Would something like this prevent malicious PDF file from opening/running? Or could you have a syntactically-correct PDF file that is also malicious? submitted by /u/SteeleDynamics [link] [comments]

[Request] Accelerometer data for crashes Posted: 01 Aug 2019 11:31 AM PDT Does anyone have any public accelerometer data for car crashes and accidents? My friend and I are trying to create an accident classifier that will send an alert if any accidents happen. Thanks in advance. submitted by /u/GodzCooldude [link] [comments]
