Writing map-reduce jobs

to process data is not a

trivial experience. This is a

time-consuming task, even

for a seasoned Java or C#

programmer. Hive is a useful

tool for creating and running

map-reduce jobs in Hadoop.

HiveQL is a declarative

language, modelled to provide

a similar experience to writing

SQL: you construct and run

the statement, submitting it

to a query engine; the query

engine transforms the query

into a series of map-reduce

jobs. By not having to worry

about the low-level coding

you become more productive

and can concentrate on data

analysis. This session will

get you up to speed with

Hive, and includes several

practical examples.

Having accurate row

estimates is crucial to obtain

the best query plans. In SQL

Server 2014, the cardinality

estimating calculators have

been vastly overhauled

based on a decade or more of

real-world experience with the

most difficult query patterns.

Among the patterns that

give improved estimates

are ever-increasing

keys and columns with

correlation. One of the most

interesting features is the

instrumentation of the

cardinality calculators through

extended events; you can see

how the estimate is produced.

With the introduction of

version 11, C++ is enjoying a

renaissance. But the changes

are so substantial that it’s

now almost an entirely new

language. The new C++

style is based on lambda

functions, rvalue references,

automatic type inference,

variadic templates, new

standard library collections,

smart pointers and many

other features. In this session,

Goldshtein will show how

these features fit into existing

C++ programs and how

modern C++ development

is up to par in productivity

and performance with any

other language.

Messaging is one of the

most effective ways to pass

non-time-critical information

between servers. It’s ideal for

use with remote databases,

logging, monitoring and

so forth. RabbitMQ is one

of the most flexible of the

messaging systems. It’s robust,

open source, easy to use and

supports pretty much all of the

developer platforms. In this

session, Holub will discuss

messaging in general and

how best to apply it in your

application. He then goes on to

discuss Rabbit’s architecture

and programming.

Excel is the analytical tool in

the Microsoft Office suite for

analysing both relational and

unstructured big data. In this

session, Sarka explores some

of Excel’s technologies: Power

Pivot, through which Excel

becomes a single-user analysis

service in tabular mode; Power

View and Power Map, for

creating ad-hoc reports on the

tabular model with minimal

effort; and Power Query, giving

you a data search engine,

so you can query data from

within your business and from

external data sources. Sarka

will also discuss the Office 365

BI sites, which provide the

infrastructure for publishing

your reports, if you do not use

an internal infrastructure.

You have been trying to learn

TDD, and it’s going pretty well,

but your code looks horrible.

Your design skills are lacking,

and trying to let TDD drive the

design without having design

skills can lead to a problematic,

although testable, design of

your code. This workshop will

specifically deal with design

skills, and assumes that you

already know how to write

unit tests. In this session,

Osherove, the author of “The

Art of Unit Testing ”, walks

through important techniques

for refactoring and design

of code that will be either

test driven or refactored for

testability as part of a test-

driven legacy effort. He will

give real examples in .NET

and Java. And most of the

workshop will be hands-on

pairing and refactoring on real

code. Osherove will cover the

following topics: clean code

When it comes to writing code,

a seemingly endless stream

of new frameworks hits the

streets every year to help you.

Or even every month. And,

yes, frameworks can help you

write better code faster. But

also, once you apply one or

more frameworks to a project,

trouble begins. What if you

require features that aren’t

implemented? What if it

contains bugs or omissions?

And what if a new version is

released that is implemented

differently? These problems

can bring your project a halt.

In this session, Hoogendoorn

demonstrates pragmatic

architectures and patterns

that will help your projects

avoid framework issues and

to keep code independent of

framework choices.

It seems that Node.js is the

coolest kid on the block.

More and more companies,

from start-ups to giants such

as Microsoft and Linkedin,

are using Node.js in their

applications. But can this

framework compete

with a veteran such as

ASP.NET? There are many

considerations for using either

but, in this session, Rodenski

and Flatow will just let the

frameworks fight it out.

Discover what’s new in Visual

Studio 2013. In this session,

you can hear from Microsoft

about new features around

developer productivity, web

development, Windows 8.1

app development, .NET 4.5.1

and Team Foundation Server.

Davies will outline what’s new

in 2013, and provide numerous

demonstrations in each of

these areas. Knowledge of

earlier versions is assumed.

design for testability;

refactoring patterns on hard-

to-test legacy code; writing

tests against refactored code;

when it does and does not

make sense to refactor; and

open-source projects and how

we would refactor them.
