Using the Playlist

by Shaun Friedman | June 2014 | Cookbooks

In this article by Shaun Freidman, author of the book FL Studio Cookbook, you can learn to arrange the many pieces and parts of your production by pasting patterns in FL Studio. You may also paint automation curves and record external audio in the playlist. The playlist is where you can specify which patterns are played (or not played) at which point in time. You can actually make a full-length song with one pattern by using the Piano roll and by continually adding more beats and bars with data. Thus, beats per bars is the area where you can distinguish between an intro, verse, chorus, bridge, outro, or any type of section of your song. It is all up to the individual artist using FL Studio to decide their particular musical arrangement. This is shown in the first recipe Using patterns to build a song.

In this article, we will cover the following topics:

  • Using patterns to build a song
  • Comparing patterns and audio
  • Using markers and snap
  • Viewing the playlist

What is Quantitative Finance?

by Alonso Peña, Ph.D. | June 2014 | Open Source

In this article by Alonso Peña, Ph.D., author of Advanced Quantitative Finance with C++, we will give a brief introduction to Quantitative Finance, delimit the subject to option pricing with C++, and describe the structure of the article.

Quantitative Finance studies the application of quantitative techniques to the solution of problems in finance. It spans diverse areas such as the management of investment funds and insurance companies, the control of financial risks for manufacturing companies and banking industry, and the behavior of the financial markets. Quantitative Finance is eminently interdisciplinary building upon key expertise from the disciplines of finance, mathematics, and informatics.

In this article, we will focus on one aspect of Quantitative Finance—the pricing of financial derivatives using the programming language C++. In the following sections, we will describe the main features of the three key disciplines that constitute Quantitative Finance:

  • Finance

  • Mathematics

  • Informatics

Discovering Python's parallel programming tools

by Jan Palach | June 2014 | Open Source

In this article by Jan Palach, author of Parallel Programming with Python, we will expose some Python libraries to implement parallel solutions.

The Python language, created by Guido Van Rossum, is a multi-paradigm, multi-purpose language. It has been widely accepted worldwide due to its powerful simplicity and easy maintenance. It is also known as the language that has batteries included. There is a wide range of modules to make its use smoother. Within parallel programming, Python has built-in and external modules that simplify implementation. This work is based on Python 3.x.

Shaping a model with Meshmixer and printing it

by Richard Salinas | June 2014 | Cookbooks Open Source

In this article by Richard Salinas, author of the book 3D Printing with RepRap Cookbook, has discussed about shaping a model and then printing it. We're going to take the models that are scanned with 123D Catch and make them better. We'll do this by using Meshmixer, the free program offered by Autodesk. Meshmixer is a 3D modeling program that offers a variety of sculpting tools that manipulate the surface mesh of a 3D model. It also offers a series of tools that are geared to optimize a model for 3D printing. We'll improve the surface of a model by working with its mesh. Later on, in the printing section, we're going to learn how to optimize what we can't see of the model.

Common performance issues

by Osama Oransa | June 2014 | Enterprise Articles

In this article by Osama Oransa, author of Java EE 7 Performance Tuning and Optimization, we will discuss the most common performance issues, classify them, describe the symptoms, and analyze the possible root causes.

Let's now go through the most common performance issues in enterprise applications that we could face during performance troubleshooting. For each issue, we will define the issue, describe it and its symptoms, and give examples. Let's begin with classifying the most common issues and organizing them into different categories.

Using the client as a pivot point

by Kevin Cardwell | June 2014 | Networking & Telephony Open Source

This article is written by Kevin Cardwell, the author of the Building Virtual Pentesting Labs for Advanced Penetration Testing book. This article is about using the client as a pivot point.

When we compromise a machine, the next thing we want to do is use the client source to our advantage. This is because we know most networks are configured with the locations that are inside the network architecture being considered at a higher level of trust and not with a location that is outside the network. We refer to this as pivoting.

(For more resources related to this topic, see here.)

Writing Tag Content

by Vitor Subtil | June 2014 | Cookbooks Open Source

The article by Vitor Subtil, the author of Near Field Communication with Android Cookbook, explains that the NFC Forum is responsible for developing standards-based NFC specifications to allow interoperability between different devices and tags. One of the specifications created by the NFC Forum is NFC Data Exchange Format (NDEF). The NDEF specification defines the message encapsulation format to exchange information between two NFC-enabled devices or devices with the NFC tag. NDEF is a lightweight, binary message format that can be used to encapsulate several custom payloads. Using this abstraction layer allows us to create the standard tag content compatible with all the NFC Forum tag types, ignoring the fact that each tag type has different hardware setups and memory layouts.

In this article, we will cover the following topics:

  • Working with the NDEF record
  • Writing a URI-formatted record
  • Writing a text-formatted record
  • Using Android Application Record
  • Working with external types
