Ghostery Goes Open Source, Reveals Two Proposed Revenue Streams

Ad-blocker Ghostery published its entire programming code on Thursday. By going open source, the company aims to clear the air on its old business model and invite others to contribute to its continuing development.

“As a privacy product, especially one designed to give users a look behind the scenes at what data companies are collecting and doing with it, we thought it was important to give our users a look under the hood,” Ghostery’s product manager Jeffrey Tillman said.

This unprecedented move was Ghostery’s response to conspiracy theories hounding the company. Before its acquisition by web browser Cliqz last year, previous owner Evidon earned money for Ghostery by selling users’ data. Software users chose to disclose information on ad trackers they encountered, but the compiled information was sold to eCommerce sites to help them discover why loading times slowed down.

Ghostery’s old business model was contradictory—a privacy-focused tool selling user data—and confused its users. “It was never a really great fit for Ghostery the consumer product,” Tillman admitted.

Recently, Ghostery announced two revenue streams as its new business model. First is Ghostery Insights, a paid analytics service for researchers to gather more data about the tracker ecosystem. Likewise, the analytics tool will aid web developers in quantifying the effect of trackers on site performance, such as loading speeds.

Meanwhile, Ghostery Rewards is an affiliate marketing program designed for its users. They can choose to sign up for the service wherein users will receive relevant promotional offers, a tamer version of aggressive web ads. There will still be advertisements, but only those worthwhile and interesting to Ghostery users.

Of course, affiliate programs are nothing new as many publications and bloggers already use them to generate revenue. However, Ghostery’s decided to make its program distinctly different from that of its main rival Adblock Plus. Unlike Ghostery Rewards, Adblock has an “acceptable ads program” that shows ads that may not be relevant to the user. As long as advertisers meet certain criteria and agree to split some of their ad revenue, Adblock lets them through.

Exposing Ghostery’s code to the public makes it more vulnerable for software developers to sidestep the ad blocker’s system. But Tillman isn’t losing sleep over it.

“There will always be a cat-and-mouse game with advertisers that are trying to find new ways to evade our technology but, if anything, going open-source should empower our community of contributors to help keep Ghostery ahead of the curve,” Tillman pointed out.

Yahoo Reveals Its Search Secrets, Vespa Tool is Now Available as Open Source

Yahoo is now giving away the crucial technology powering its internal searches. Vespa, the search engine used by the tech company for internal queries, is now open-source and available to everyone.

Oath Inc., the Verizon company that acquired Yahoo in June, announced that Vespa is now available as open source on GitHub. According to a company blog post, making the Big Data processing and serving engine open source is a step further in Oath’s commitment to opening up its infrastructure to developers.

“By releasing Vespa, we are making it easy for anyone to build applications that can compute responses to user requests, over large datasets, at real time and at internet scale – capabilities that up until now, have been within reach of only a few large companies,” Jon Bratseth, a systems architect at Yahoo, explained via the blog post.

Vespa powers Yahoo network’s internal search feature and is used to determine what recommendations to display as well as the company’s ad targeting system. Currently, Vespa is used in around 150 apps such as Yahoo’s main search engine, Yahoo Mail, and Flicker, CNBC reported. The search tool is also responsible for serving around 3 billion native ads daily.

Vespa traces its roots back to AllTheWeb, a Norwegian search engine which was acquired by Yahoo in 2003, according to Wired. Since then, the tool has been modified as a general purpose engine that Yahoo could use internally in a host of different applications.

This is not the first time Yahoo released some of its technology as open source. In 2009, the company released Hadoop as open source which became a hit when it was adopted by big tech companies such as Facebook, Twitter, and eBay. Apparently, the plan is to replicate the benefits of making Hadoop publicly available which allowed Yahoo to easily recruit programmers as it became widely used.

But Vespa’s reach has the potential to overshadow that of Hadoop. As Bratseth puts it, “Vespa is larger in scope and lines of code than any open source project we’ve ever released,” adding that it has already been battle-proven in Yahoo’s largest and most critical systems. It is attractive both for its scalability and versatility while it is touted to be better than Hadoop in serving results to end users.

However, there are doubts that Vespa could be successful outside of Oath. According to Wired, Hadoop became a success because it was born open source and arrived at a time when businesses needed it most. This time, however, most large companies have already addressed web search issues that Vespa is designed for. In addition, there are already other open source engines available.

Apple Shares Source Code For Machine Learning Framework at WWDC 2017

Apple’s recent WWDC (Worldwide Developers Conference) saw the unheralded release of Core ML, which will reportedly make it easier for developers to come up with machine learning tools across the Apple ecosystem.

The way this works is that developers need to convert their creations into an API that is compatible with the Core ML. They then have to load their programs into the Apple Xcode development before it can be installed on the iOS.

Developers can use any of the following frameworks: Keras, XGBoost, LibSVM, Caffe, and scikit-learn. To make it even easier for them to load their models, Apple is allowing them to come up with their own converter.

According to Apple, the Core ML is “a new foundational machine learning framework used across Apple products, including Siri, Camera, and QuickType.”

The company explained that this new machine learning tool would be “the foundation for domain-specific frameworks and functionality.”

One of the primary advantages of the Core ML is that it speeds up the artificial intelligence on the Apple Watch, iPhone, iPad, and perhaps the soon-to-be-released Siri speaker. If it works the way that is billed, any AI task on the iPhone, for instance, would be six times quicker compared to the Android.

The machine learning tools supported by Apple Core ML include linear models, neural networks, and tree ensembles. The company also promised that private data by users won’t be compromised by this new endeavor. This means that developers can’t just tinker with any phone to steal private information.

Core ML also supports:

  • Foundation for Natural Language Processing
  • Vision for Image Analysis
  • Gameplay Kit

“Core ML itself builds on top of low-level primitives like Accelerate and BNNS, as well as Metal Performance Shaders,” the company added.

But Apple is reportedly not content with just releasing the Core ML. According to rumors, the company is looking to fulfill its promise of helping to build a very fast mobile platform. In fact, if the rumors are true, the company is also building a much better chip that can handle AI tasks without compromising performance.

Though Core ML seems promising, Apple is certainly not blazing the trail when it comes to machine learning. In fact, Facebook and Google have already unveiled their own machine learning frameworks to optimize the mobile user’s experience.

The new machine learning framework is still part of Apple’s Core Brand, which already includes Core Audio, Core Location, and Core Image as announced earlier.

Solar Power – The Perfect Energy Source

Solar energy is the light and the heat from the Sun. This energy is free, unlimited and, it doesn’t cause any pollution, which makes it the perfect source of power. With the availability of very low priced easy to install DIY solar systems, certainly, there has never been a better time to take advantage of this remarkable, infinite energy source.

There are lots of ways in which we are able to harness the power of the sun. In warm countries for example, solar furnaces are able to be used as means for cooking food. A solar furnace is merely a huge array of mirrors used to concentrate the Sun’s power into a small area and produce quite high temperatures. They are generally referred to as solar cookers.

The movie ‘Race the Sun’ was a story concerning low- income and under achieving Hawaiian students, advised by their teacher to join the Solar Car Race. In the movie, an automobile the same shape as a cockroach and covered with solar panels utilised the Sun’s rays as an alternative source of energy to run the vehicle.

Since Roman times we have been using the Sun as an effective method of obtaining electric power. Nowadays nonetheless we have created solar thermal solutions which are put to use for water heating, space heating, space cooling and process heat generation. Solar technology is also used to distil water and even transform saline or brackish water into something that is drinkable. Solar water disinfection or SODIS as it’s commonly known, involves subjecting water-filled plastic polyethylene terephthalate or PET bottles to the Sun, whereby UV-radiation kills diarrhoea generating bad bacteria. The SODIS-method helps to defend against diarrhoea and and in so doing is saving lives of people. In excess of 4000 children die each and every day from the effects of diarrhoea. This technique does rely on climate conditions, but given that the most crucial demand for water is located in hot countries this is when this system is most effective. Currently, you will find in excess of two million people in developing countries who rely upon SODIS for everyday drinking water needs.

Daylight systems are also being used to optimize the power emitted by the sun. A Daylight System is used to provide interior illumination, thereby replacing the need for artificial lighting. Daylight systems include things like sawtooth roofs,, skylights, and light tubes. Where daylight systems are correctly implemented they’ll reduce lighting-related energy consumption typically by 25 percent.

One of the fastest growing areas regarding the utilisation of solar power is in the use of photovoltaic or PV panels which can be used to convert the sun’s rays directly into electricity. To start with solar energy was only utilized to power modest appliances and equipment, such as calculators that are powered by way of a single solar cell. Even though water and space heating tend to be the most commonly used applications of solar energy, the advancement of photovoltaic technology now means that a lot more families are using solar energy to supply either a significant percentage or even all of their energy needs.

One of the main concerns associated with the usage of solar energy with regard to domestic properties has been the expense of fitting such a system. Several thousand dollars were required simply to pay for installing a fairly modest system. Today however, the availability of DIY solar energy materials, and indeed complete kits, has meant that superb systems can easily be installed for mere 100’s of dollars.

Why Solar Energy Is a Good, Renewable Energy Source?


These days we hear a lot about using organic products, biodegradable products, recycling plastics, etc., to minimize carbon footprint and save the environment. But we do not realize that unless and until we minimize consumption, we can not really save our environment. For example, look at the world consumption; Today’s products are manufactured, used and disposed of at a higher rate than the earth can accommodate in a less harmful way. Therefore it is important that we move to green alternatives now, otherwise, will be covered by pollutants and toxins produced in the normal course of the manufacture of non-biodegradable products like plastics. In this article, we will discuss as a green alternative that has a remarkable effect on reversing the negative effects that we created by technological progress and industrial revolution.

There are many ways to fight climate change, but the transition to a power of clean, renewable solar power is an ideal way. So let’s look at some of the interesting facts about solar energy.

· It is the most abundant source of energy. The amount of energy the Earth receives in one minute is approximately 10,000 times the energy needed worldwide.

Undoubtedly, solar energy is the energy source of cleaner available on the planet. Unlike fossil fuels, solar power produces no toxic byproducts. Solar panels use photovoltaic system that has no harmful effect on the environment and humans.

· Solar energy is practical, versatile and flexible in relation to wind energy and the main source of solar energy is the sun that is accessible to all parts of the globe. Unlike hydropower (which is also a source of renewable energy and cheap energy), solar power is not a threat to marine life and / or people on Earth.

· Worried increase utility bills and looking for a way out? Well, solar energy is the solution. By installing solar panels will not only reduce their utility bills, but is also increasing the value of your property. Although solar panels are little expensive at first, they turn out to be efficient and profitable in the long term. The best part is they do not require much maintenance and saves additional costs as well as being sustainable.

One of the misconceptions about solar panels is that they are expensive and affordable only to the elite class is wrong. Solar panels require an investment of time after which you do not have to invest in regular maintenance. In fact, in most countries, the government provides special tax benefits and other advantages of solar energy. Once installed solar panels, freedom of utility bills is obtained, power outages and enhance the value of their property by being friendly to the environment.

Solar Energy: An Environmentally Friendly Energy Source

Regardless of your setting, choosing solar energy will help you lower your energy costs. It has been proven that energy costs double approximately every ten years. This should help you realize that you should do something about your energy costs. You’ll learn some of the ins and outs of solar energy by reading this article.

The amount of energy produced depends on the efficiency of your solar panels as well as the number of solar panels installed. Do the math and figure what you require. You may get better results using a few high performance panels instead of many less efficient ones.

When it comes to your efforts to rely on solar energy, take it one step at a time. Consider adding solar lights throughout your landscaping. You will save energy and help your planet. You can find these in almost any type of home improvement store. The installation doesn’t get much easier. They simply need to be placed along walkways, in the ground.

Once you have produced solar energy, you will have to have a reliable storage device for it. You should invest in a high-capacity battery, that will store for extended periods. You could also explore options for selling your excess energy to the electric company.

Panels that are easily rotated have the best efficiency. If you have to put in panels with fixed angles, try to position it so it will work for both winter and summer months.

Even locations with cold weather and clouds can benefit from switching to solar energy. Direct sunlight isn’t necessary, nor is a particular temperature. As a matter of fact, lots of people claim that they have incredible solar power on cloudier days.

Don’t let a salesman sell you anything. Take your time and do your research to make the smartest and most appropriate choice. When you buy without thinking, you may be taken advantage of.

Solar powered attic fans are great if you can’t fully transition to solar energy. An attic fan will sense the temperature and turn itself on when your attic reaches a specific temperature. This will remove your home’s heat and lower cooling costs. This is a great option because it costs you nothing to run it, since it is completely powered by the sun.

Though solar panels are put in areas with the most sunlight, some factors could affect the sun getting to them. Be sure to do regular checks to ensure that trees are not growing up and blocking essential sunlight from reaching the solar panels.

Be sure to check the design date of each type of solar panel you consider purchasing. Many current technologies are better, but some panel vendors sell technology that’s a couple years old. This older technology is more affordable but you will get much better results with a more recent product.

Check your local and state regulations before installing a solar system. In some areas, you must have special permits. If you do not have a permit and install a unit, it is subject to removal.

Pay attention to the weather if you’re thinking about installing solar panels. You need at least five hours of sunlight every day to get the most use out of them. However, if your area experiences a lot of cloudy days or large amounts of snowfall, you may need to explore other green energy sources.

Take stock of the shade around your house when considering solar power. Solar power is not a good option for you if your property is constantly shaded. If a shadow is case over your solar panels, their efficiency could drop by as much as 80%, which means you should consider other forms of green energy.

Leasing a set-up is a great way to start the switch to solar power. It costs less up front and yet still pays for itself over time.

Solar panels contribute to your home’s energy in a lot of different ways. Solar energy provides a great deal of heat, which can be harnessed to heat water or other items in your home. Often these systems are less expensive as you don’t need the ability to turn that heat into electricity in you power expenses.

Consider how best to use solar power in your residence. For instance, solar panel systems often can only partially heat a home. But, they are generally able to make sufficient energy to power a water heater. These types of facts can help you make the right decisions.

Solar energy can improve millions of lives while also aiding the environment. Hopefully you have found that going green by using solar energy is possible and is a great decision. There is so much to learn about solar energy, so take the information from this article and build on it until you really understand what it is all about.

A Bright Future for Solar Energy: An Alternative Energy Source


I was first introduced to solar energy in the movie, Race the Sun with James Belushi and Halley Berry in the lead. It was a story about low- income and under achieving Hawaiian students encouraged by their teacher to join the Solar Car race. In the movie, a car shaped like a cockroach and covered with solar panels used the sun’s rays as an alternative energy source to run the car.

Solar energy is the light and the heat from the sun. Solar energy is free and its supplies are unlimited. There are n air and water pollution caused about by using solar energy. But there is still some impacts on the environment although indirect.

Photovoltaic cells used to convert sunlight into electricity uses silicon and also produce some waste materials. There are also large solar thermal farms and these farms can also be harmful to the environment and desert ecosystems if not properly managed.

Solar energy can be used on different aspects. Solar energy can be used in agriculture. Greenhouses (which is entirely different from greenhouse gas) convert solar light to heat to be maximized in enhancing the growth of plants and crops. Greenhouses has been around since the Roman times and modern greenhouses were built in Europe in 16th century. Greenhouses are still an important part of horticulture nowadays,

Daylight systems are also being used to maximize the energy released by the sun. It is used to provide interior illumination replacing the artificial lighting. Daylight systems include sawtooth roofs, light shelf, skylights, and light tube. Daylight systems when they are properly implemented can reduce lighting-related energy consumption by 25 percent.

Solar energy can also be developed into solar thermal technologies which can be used for water heating, space heating, space cooling and process heat generation. Solar energy can also be used to distil water and make saline or brackish water potable or drinkable.

The solar water disinfection or SODIS involves exposing water-filled plastic polyethylene terephthalate or PET bottles. This process takes a long time, since the exposure time varies on the weather conditions. It requires a minimum of six hours to two days during days with overcast conditions. Currently, there are two million people in developing centuries use SODIS for their daily drinking water needs.

Also sunlight can be converted into electricity using photovoltaics or PV. PV has been mainly used to power small and medium-sized things like a calculator powered by a single solar cell. There are homes powered by photovoltaics. Using solar energy for water and space heating is the most widely use application of solar energy. While ventilation and solar air heating is also growing in popularity.

There are three main ways in using solar energy. The main way of using and converting solar energy is by using the solar cells. Solar cells convert light directly into electricity. Solar cells are also called photovoltaic or photoelectric cells.

Meanwhile, solar furnaces use a huge array of mirrors to concentrate on the Sun’s energy into a small space and produced very high temperatures. Solar furnaces are also called “solar cookers”. A solar cooker can be used in hot countries to cook food.

With all the benefits if using solar energy, there is still a downside for this alternative energy source. It does not work during night time. The cost of setting up solar stations is expensive, but the benefit of using solar energy when accumulated is so much more.
