Aaron Patterson's talk from Future Insights Live 2014 in Las Vegas: "The Web is constantly changing, and technology is constantly evolving. With these ideas in mind, let's look at what Ruby and Rails not only can do, but must do in order to push technology forward on the web." Miss his talk?

71. Back to Future Predictions…

73. Future of
Programming Languages

74. Machine Code

0 1 2 6 0 32 decimal
000000 00001 00010 00110 00000 100000 binary

75. Assembly Language

76. Freed us from binary

77. C
void loop(void) {
green();
dht * fridge = malloc(sizeof(dht));
read = dhtRead(fridge);
!
if(DHT_OK == read) {
WRITE_TEMP(fridge->rhIntegral,
fridge->rhDecimal,
fridge->tIntegral,
fridge->tDecimal);
} else {
red();
WRITE_TEMP(99, 99, 99, 99);
}
delaySeconds(2);
}

78. Freed us from the instructions

79. Java
public IRubyObject start_document(ThreadContext context, IRubyObject version, IRubyObject tags,
IRubyObject implicit) {
boolean implicitBool = implicit.isTrue();
Map<String, String> tagsMap = null;
!
RubyArray tagsAry = tags.convertToArray();
if (tagsAry.size() > 0) {
tagsMap = new HashMap<String, String>(tagsAry.size());
for (int i = 0; i < tagsAry.size(); i++) {
RubyArray tagsTuple = tagsAry.eltInternal(i).convertToArray();
if (tagsTuple.size() != 2) {
throw context.runtime.newRuntimeError("tags tuple must be of length 2");
}
IRubyObject key = tagsTuple.eltInternal(0);
IRubyObject value = tagsTuple.eltInternal(1);
tagsMap.put(key.asJavaString(), value.asJavaString());
}
}
!
return this;
}

80. Freed us from memory
management.

81. Ruby
def start_document(context, version, tags, implicit)
tagsMap = nil;
!
tagsAry = Array(tags)
if (tagsAry.size > 0)
tagsMap = {}
tagsAry.size.times do |i|
tagsTuple = tagsAry.eltInternal(i)
if (tagsTuple.size != 2)
raise RuntimeError, "tags tuple must be of length 2"
end
key = tagsTuple.eltInternal(0);
value = tagsTuple.eltInternal(1);
tagsMap[key] = value
end
end
end

82. Freed us from Types

83. We’ve eliminated
• Specific machine code
• Particular CPU instructions
• Memory management
• Object Types

84. What’s next?

86. Concurrency

87. CPUs aren’t getting faster

88. We’re getting more cores

89. Today
lock.synchronize {
# Manipulate some data
}

90. Today
pool = ThreadPool.new NUMBER_OF_CPU

91. Thinking about this is a
waste of time!

92. Dealing with concurrency is
CODE NOISE

93. The computer should solve
these problems FOR US!

94. Distributed Systems

95. Concurrency tomorrow will be
like memory management today

96. Future of Ruby

97. Ruby will ADAPT.

98. By STEALING

99. Clojure, Haskell, Go

100. GC was invented in 1959.

about.

120. The pendulum is done.

121. Why is multi-core different than
distributed computing?

122. Why is distributed computing
different than client/server?

123. Practical Terms

124. Better API support

125. High Productivity
