Sua Linguagem Preferida - a sua maior fraqueza.

A maioria dos programadores, se não todos, pode dizer que tem uma linguagem preferida. O que é muito natural, aquela linguagem em que nos sentimos fluentes. Mas em que idioma pensam pessoas poliglotas? Sabe aquele exemplo clássico da palavra saudade que só existe em PT-BR? É discutível: mas já pensou que a riqueza de vocabulário (ou mesmo fluência em vários idiomas) pode mudar a forma como você enxerga o mundo? Podemos aplicar as mesmas ideias quando se trata de programação? É sobre as fronteiras que ficam entre as linguagens de programação que eu quero conversar.

11. almost. non. technical. at all.
12. Let’s Talk.
13. sua linguagem preferida - a sua maior fraqueza -
14. does language limit thoughts?
22. I don't think that we think in language, or think in words. I think we think in visual images, we think in auditory images, we think in abstract propositions about what is true about what. And I think that language is a way of communicating thoughts, of getting them out of one head and into another by making noise. "steven pinker

24. context drives language?
26. um
27. um alguns
28. um alguns véi, umas par deles!
29. .
33. language limits our ability to externalize.
34. how hard is it to build in [lang]?
35. how hard is it to build in c++?
36. how hard is it to build in ruby?
37. how hard is it to build in java?
38. how hard is it to build in brainfuck?
39. scheduling - a pain in the neck -
40. knows: - ruby - js - java - csharp valeriano hates: - csharp likes: - ruby
41. knows: - brainfuck - ruby - csharp folha hates: likes: - brainfuck
42. Let’s read some code.
43. #knows(valeriano, ruby). #likes(valeriano, ruby). #hates(valeriano, csharp).
44. @valeriano = { name: "valeriano", knows: %i{ ruby java csharp js }, likes: %i{ ruby js }, hates: %i{ csharp } } #knows(valeriano, ruby). #likes(valeriano, ruby). #hates(valeriano, csharp).
45. rule teaches(Person, Lang) if knows(Person, Lang), !hates(Person, Lang).
46. rule teaches(Person, Lang) if knows(Person, Lang), !hates(Person, Lang).
47. rule teaches(Person, Lang) if knows(Person, Lang), !hates(Person, Lang).
48. rule teaches(Person, Lang) if knows(Person, Lang), !hates(Person, Lang).
49. rule teaches(Person, Lang) if knows(Person, Lang), !hates(Person, Lang).
50. rule teaches(Person, Lang) if knows(Person, Lang), !hates(Person, Lang).
51. rule teaches(Person, Lang) if knows(Person, Lang), !hates(Person, Lang).
52. Let’s read more code.
53. # teaches(person, lang) if # knows?(person, lang), # !hates?(person, lang)
54. # teaches(person, lang) if # knows?(person, lang), # !hates?(person, lang) def teaches(person, lang) knows?(person, lang) && !hates?(person, lang) end
55. # teaches(person, lang) if # knows?(person, lang), # !hates?(person, lang) def teaches(person, lang) knows?(person, lang) && !hates?(person, lang) end def knows?(person, lang) if person[:knows].include?(lang) return true end end
56. scheduling: complex rules. - a pain in the neck -
57. rule teaches(Person, Lang) if knows(Person, Lang), !hates(Person, Lang).
58. rule teaches(Person, Lang) if knows(Person, Lang), !hates(Person, Lang), !gave(Person,last_month, Lang).
59. a little more code
60. @valeriano = { name: "valeriano", knows: %i{ ruby java csharp js }, likes: %i{ ruby js }, hates: %i{ csharp } }
61. @valeriano = { name: "valeriano", knows: %i{ ruby java csharp js }, likes: %i{ ruby js }, hates: %i{ csharp }, gave: { %i{ java } } }
62. @valeriano = { name: "valeriano", knows: %i{ ruby java csharp js }, likes: %i{ ruby js }, hates: %i{ csharp }, gave: { last_month: %i{ java } } }
63. scheduling: rule - a pain in the neck -
64. def teaches(person, lang) end person[:knows] - (person[:hates] + person[:gave][:last_month]). include?(lang)
65. def teaches(person, lang) end person[:knows] - (person[:hates] + person[:gave][:last_month]). include?(lang)
66. def teaches(person, lang) end person[:knows] - (person[:hates] + person[:gave][:last_month]). include?(lang) nil?
67. @folha = { name: "folha", knows: %i{ ruby csharp brainfuck }, likes: %i{ brainfuck }, hates: [], gave: { last_month: [] } }
68. how hard is it to build in ruby?
69. we need the rule algorithm.
70. what if…?
71. knows(valeriano, ruby). knows(folha, ruby). likes(valeriano, ruby). likes(folha, brainfuck). hates(valeriano, csharp). gave(valeriano, last_month, java). teaches(Person, Lang) :- knows(Person, Lang), \+ hates(Person, Lang), \+ gave(Person, last_month, Lang).

77. web scale!!!!11
79. language do not create thoughts.
83. can has web scale!!!!11
86. how hard is it to build in ruby?
87. ER L A NG AL L T HE T H I N GS !!!!1
89. ruby ecosystem is a great thing.
90. … if I’m doing this work, and it feels hard and frustrating, but I KNOW that concurrency is becoming more and more important. And I know that there are languages like Erlang and many others that solve this [concurrency] well… I need to do something! " José Valim

93. import Supervisor.Spec children = [ supervisor(TCP.Pool, []), worker(TCP.Acceptor, [4040]) ] Supervisor.start_link( children, strategy: :one_for_one)
94. This has been my first week with Elixir, and I’m pretty excited. Elixir has a non-scary syntax and combines the good features of Ruby and Erlang. It’s not Erlang and it’s not Ruby and it has ideas of its own. "Joe Armstrong
95. Senhor Folha
97. wrapping up!
98. context drives language?
99. context drives language!
100. language just externalize.
101. understand the context to enhance comprehension.
102. use languages as tools.
103. be happy.
