The most basic guitar effects

Apart from being able to play one of the coolest musical instruments ever, guitarists are also blessed with the ability to freely customize their sound with the use of different pedals. These pedals allow one to add to the guitar’s original sound to achieve vastly different effects. The array of effects to choose from is simply endless.

This variety is undoubtedly a good thing but beginners will often feel overwhelmed with their choices. And not many people can afford to buy ten different guitar pedals at once. What you buy will ultimately depend on your own preferences and the effects you want to achieve but there are some basic pedals that will serve as a good introduction to guitar sound effects.

Tuning pedal

This is the foundation of any pedalboard. A tuning pedal allows you to tune your guitar with great precision so that you never have to hear yourself play out of tune again. A tuning pedal also is usually equipped with many other useful options, like muting your guitar with a flip of a switch while you tune it.

EQ pedal

EQ pedal’s purpose is to adjust the sound frequency. It’s a very versatile pedal that can be used in two ways: before the amplifier to modify the sound that goes into it or after the amplifier to ‘amplify’ the effects of the amp and the volume. An EQ pedal is also very useful if your guitar or your amplifier have problems with producing a clear sound.

EQ stands for equalizer and it’s a way of making your sound more or less prominent on certain ends of a spectrum. For example, you can reduce the high frequencies to make the bass sound more gentle. You can increase the mid frequencies to make yourself more heard over surrounding noise – this is used when playing with a band. An EQ pedal is equipped with various settings and it is a joy to discover what they all do. If you aren’t sure which one to go for, these eq pedals should provide you with everything you need.

Pitch pedals

The pitch pedals group includes the many kinds of pedals whose purpose is to alter the pitch of the sound. The tuning pedal is one example. Changing the pitch is how you produce a unique sound that can become your signature when playing guitar.

Pitch shifter pedals make the sound go from one pitch to another in a fluent sweep. An octave change like that is sure to grab the listeners’ attention. An octave pedal adds another sound on top of the original one. The additional sound is an octave higher or lower. Here you will find octave pedal reviews.

Whatever you go for, make sure that you do your research beforehand. The best idea would be to go to a music store to try them out for yourself but that’s not always possible. To hear how each pedal sounds in action, you can listen to musicians showing their pedal effects in YouTube videos.

Why should you add dehydrated fruits to your diet?

There are quite a few reasons that make dehydrated fruits complementary to one’s diet. Firstly, they hold numerous health benefits and energy supplies that could boost your mental and physical well-being. Secondly, they are tasty snacks that could easily substitute a regular chocolate bar and give you a much richer vitamin intake.

What are the benefits of dehydrated fruits?

  • light on the stomach
    One of the perks of low water intake from dried fruits is not overpowering the digestive process, unlike oily or fatty foods, which give the stomach a hard time.
  • rich in nutrients and fibers
    On both fiber and nutritional levels, dried fruits perform outstandingly. From vitamins to iron, calcium, and potassium, it’s hard to establish a dried-fruits-based diet and not supply yourself with these nutrients.
  • rich in calories
    Dehydrated fruits concentrate the calories necessary for energy during the day or for exercising at the gym. Also, they are a great substitute for fat dishes since they provide enough calories for us to feel sated.
  • no preservatives
    Since dried fruits don’t need any chemicals to maintain their richness in nutrients, you won’t have to worry about being allergic to such additives.

Ways to dehydrate fruits

Food dehydrator

If your countertop is empty enough to welcome another appliance, then you might want to supply yourself with a machine that has the singular job of drying food. Besides, if you find dehydrated fruits delicious enough, you could venture into drying other dishes too. Structurally, the best alternative should be a stainless steel dehydrator for prolonged life and sturdiness. Also, some functional aspects, such as a timer and temperature adjustment, should be prerequisites for a workable food dehydrator.


The sun holds the benefits of being at your discretion, free and bearing fruit. However, one drawback that comes along with using natural resources is the time it takes for the fruits to dehydrate and a minimum of 30 degrees Celsius for the sun to have any effect. The procedure is as follows: expose the fruits in the sun for 2 to 6 days, depending on how rapidly they dry, and make sure to deposit them inside at nighttime. Check up on them constantly to assess how fast they change.


If you’re not considering dehydrating fruits regularly or want to do it with natural resources, then an oven is a great substitute for our other mentions. The machine is fast enough for you not to lose your appetite and won’t diminish by any means the nutrient intake inside the fruit.

4 fruits that are delicious dehydrated

1. Banana

Dehydration removes all the water within a fruit, living it abundant in calories and nutrients, such as carbohydrates, potassium, and sugar.

2. Blueberries

Apart from being just as flavorsome as the original fruit, dried blueberries are rich in fibers, minerals, and vitamins, with a particular overflowing of vitamin C.

3. Watermelon

It’s hard to imagine a complete dried watermelon since we all fancy its succulence. However, dehydrated watermelon is curiously tasteful alone or accompanied by a spoonful of yogurt.

4. Citrus Slices

Since dried citrus slices are rich in fibers, they nest many health benefits. Some of the advantages of citrus dehydrated fruits are lowering cholesterol levels and decreasing blood sugar.

OCEAN – Open Cloud for Europe, Japan and Beyond

Support Action funded by European Union under the Seventh Framework Programme

A two-year project kicking off in October 2012, OCEAN will contribute to the emergence of a sustainable open cloud business ecosystem in Europe. It will do this by generating synergies and economies of scale among collaborative open source computing research projects. Only by closing the gaps, eliminating the overlaps, and avoiding the missed opportunities that often characterize open source projects will OCEAN be able to achieve its goals of fostering an open cloud ecosystem.

Creating a Directory of Open Cloud Projects

OCEAN will focus on three types of open cloud projects:

–  European FP7 research projects,
–  European national open cloud projects,
–  Japanese open cloud projects.

Four-Pronged Approach

OCEAN has developed a four-pronged approach to reach its goal of fostering the emergence of a sustainable open source cloud ecosystem and boosting market innovation in Europe. The four-point strategy is defined below:

– Creating Trust: After identifying open source projects in Europe and Japan, OCEAN will create an online Open Cloud Innovation Directory and Information Exchange Network.  With this, OCEAN will be able to collect descriptions of current collaborative projects developing Open Cloud components with special attention to software availability, licenses and technical documentation.

– Developing Synergies: To create an environment of cooperation among projects where synergies are apparent, OCEAN will propose an Open Cloud Interoperability Framework. In so doing, OCEAN will provide a relative positioning or functional mapping of these projects, in relation to key standards and reference models provided by leading standard-defining organizations such as NIST, ETSI, DMTF, OGF, etc. giving the basis for cross-projects interoperability and integration. It will be done in cooperation with projects and under guidance of specially created group of cloud experts or in the context of other established initiatives at EU level. On the basis of the framework and identified interoperability gaps between the projects, OCEAN will propose an Open Cloud Interoperability Roadmap toward the establishment of a fully operative Open Source Cloud Stack.

– Ensuring Compliance: OCEAN will certify the intrinsic quality of open source software and ensure their compliance to cloud standards. It will provide online Build, Test and Certification tools as well as a beta-test service to validate independently the quality of open source software artefacts from open cloud projects and to enable these projects to build and test their software. These services will support the projects and in so doing will motivate them to collaborate with OCEAN.

– Maintaining Action: In order to foster cooperation and integration among collaborative research projects, OCEAN will organize two annual Plugfests that will enable project teams to work on the integration and interoperability of their software. Plugfests will also be organised in cooperation with other cloud initiatives such as those organised by OGF and SNIA. OCEAN will also involve Japanese cloud experts in plugfests.


The Ocean consortium is coordinated by Fraunhofer. By bringing together organisations from Germany, France, Italy and Japan, the OCEAN project will have a positive impact in the open cloud community.

In addition to Fraunhofer, three other partners contribute their expertise to the Ocean project. Please click on their logo to learn more about each of them:

Fraunhofer – the coordinator of OCEAN – is the biggest organisation for applied research in Europe. Fraunhofer Institute for Open Communication Systems representing Fraunhofer in the consortium is a recognised expert in testing and interoperability issues including the cloud computing domain.

The global open source infrastructure software community, OW2 contributes to the OCEAN consortium with its world-class technical infrastructure, extensive experience in information sharing, outreach communication, business ecosystem building and conference organizing.

A strong industrial partner for OCEAN, Engineering Ingegneria Informatica SpA, (ENG) is a major System Integrator and Cloud provider with presence in Europe, Latin America and Middle East. The ENG R&D; lab has a long experience in European funded Projects and is pivotal for the technology innovation of the entire group.

Quality and Testing Services

Configure and execute automatically builds and tests

ETICS automates and improves the execution of builds and tests. The ETICS system is designed to simplify the development process and to support the execution of complex testing scenarios while improving the quality of the software produced. Together with its continuous build features, ETICS offers testing tools for checking various aspects of software and the opportunity to write and execute customized tests.

ETICS is a solution for software development and testing lifecycle management. It is offered as a service and exploits shared computing infrastructures to offer new and improved features.

ETICS main features


Distributed builds – You submit the builds from the web interface and ETICS allocates the required computational resources to perform the build exploiting the computing power of a distributed environment. ETICS distributes builds across different machines enabling whole projects or single components to be built in parallel.

Support for automatic creation of distribution packages – in a number of different formats (rpm, deb, tgz) on the basis of the platform selected for the build.

Dependency management – ETICS offers advanced management of build and runtime software dependencies. Within the ETICS infrastructure a large repository of Open Source third party tools is available for users to choose.


Complex testing scenarios – ETICS allows to define multi-node testing environments specifying software to install and testing scripts for each node enabling whole projects or single components to be tested against different environments and operating systems.

Distributed tests – ETICS allocates the required computational resources from its pool to perform the tests exploiting the computing power of a distributed environment and automating the execution of testing scripts. At run-time ETICS also provides a synchronization mechanism on all nodes involved in the test

Collection of test information – from popular testing libraries (e.g. junit, sloccount, pyunit, checkstyle etc.) and its integration in the build and test reports. Support for other tools can be added via plugins.


Constant quality checking of software. At every build/test, ETICS executes several specific plugins to execute source code analysis and collect measures on code quality.

Quality reports – aggregated reports as well as raw data is available for developers and managers to keep your software quality high.


OCEAN cloud projects will have the opportunity to use ETICS to configure and execute automatically builds and tests of their cloud components. The benefits will come from ETICS unique approach to standardize the build and release process and to evaluate the software quality. Most relevant quality metrics collected during build/test executions will be published in the OCEAN’s Open Cloud Directory enriching metadata associated with cloud projects.

Open Cloud Interoperability Framework

Building the framework

A key OCEAN objective is to provide an Open Cloud Interoperability Framework. This will be done by mapping the projects outcomes to the OCEAN Open Cloud reference architecture and open cloud standards.

Moreover, an open cloud roadmap will identify R&D topics to be addressed for further open cloud stack development. The project will investigate a possibility to perform this work in close contact with ETSI and even as a contribution to ETSI’s undergoing works.

The following standards will be considered :

  • OCCI: Open Cloud Computing Interface (OGF)
  • CDMI: Cloud Data Management Interface (SNIA)
  • CIMI: Common Information Model (DMTF)
  • IEEE WGs on cloud portability and Intercloud interoperability
    • Draft Guide for Cloud Portability and Interoperability Profiles ( IEEE P2301)
    • Draft Standard for Intercloud Interoperability and Federation (IEEE P2302)
  • Topology and Orchestration Specification for Cloud Applications (TOSCA)
  • Organization for the Advancement of Structured Information Standards (OASIS)
    • portability of cloud applications and the IT services that comprise them.
  • Joint ISO IEC / ITU-T work on reference architecture and vocabulary

Open Cloud Plugfests

Standards and Open Source Cloud components 

One of the OCEAN tasks is to organize Open Cloud Plugfests – open source oriented events aiming at stimulating cooperation and integration between open cloud collaborative projects. Open Cloud Plugfest main objectives include:

  •  increase awareness about the projects
  •  accelerate integration of their outcomes and foster cooperation between projects
  •  help them to increase market acceptance.

To increase the efficiency of these events, OCEAN joined the existing initiative organized by OGF, SNIA and ETSI. Together, we are building a series of Plugfest events involving Open Source and Closed Source vendors. The OCEAN project is especially supporting the involvement of Open Source Cloud projects.

Project Presentations

The OCEAN Plugfest space offers a complete table with all specific presentations used and discussed during this Brussels workshop. Do not hesitate to download the presentations from each active open cloud projects.

Workshop Overview

The workshop began by a general session during which all participating project were coached to perfectly update their listing in the OCEAN Open Cloud Directory and their mapping in the OCEAN Interoperability Framework. For maximum efficiency the workshop then splited into two tracks Architecture and Code.

  • The Architecture track was focused on Service ManagementData Management, and APIs and standards. In each session projects were invited to make a very short presentation on how the topic is addressed by them and this round of presentation was followed by an open discussion aimed at identifying project touchpoints and synergies, and at developing collaboration opportunities and commitments.
  • The Code track was dedicated to OCEAN services. It provided a hands-on tutorial on how to validate the quality of the software code based on ETICS. Software successfully validated in the workshop are granted the privilege to display the “Quality Validated by OCEAN”  logo and will be promoted by the OCEAN project.
