My G+ Collections - Focussed News on Focussed Topics

Now that Google Collections have gone live, instead receiving a single stream of mixed news and information from my profile on G+, I am able to post to the specific Collections below. By following one, or more, of these Collections you will just receive focussed news and info on that Collection or topic in your stream. So for those interested in my Green Tech news that is all you will see from my posts, if you follow just that Collection.  You can still follow my personal Profile where you will see the whole range of posts if you wish (one way to turn this down a bit is to put someone in one of your Circles, and then to change the "volume" setting for that Circle). I am also pushing all my public posts to Twitter, Tumblr and LinkedIn (and I do respond on those networks to comments posted there).

A full list of my G+ Collections can be found at bit.ly/daniecollections.

The specific topics that I am passionate about and have created Collections for are:

- Free and open source software (FOSS) at http://bit.ly/daniefoss
- Open data standards / Security / Rights / Privacy / Open Government at http://bit.ly/daniesecurity
- Technology & Gadgets in general at http://bit.ly/danietech
- Green Environment and related tech at http://bit.ly/daniegreen
- Apple Mac OS X and iOS at http://bit.ly/danieapple
- Education related tech at http://bit.ly/danieedu
- Motorcycling rides and tours at http://bit.ly/daniebike
- Gaming tech news at http://bit.ly/daniegaming
- Cape Town specific news at http://bit.ly/daniectn
- South African specific tech and news at http://bit.ly/daniesa
- LCHF & Health related tech and news at http://bit.ly/daniehealth

Ma fascineaza toate postarile tale, dar, sint atit de mica ca am ramas in urma cu dezvotarea stiintifica! Sint prea mari pentru mine! Ma depasesc desi imi plac foarte mult! Nu prw inteleg decit daca ma ajuti! Am nevoie de ajutor ca sa inteleg. Multumesc foarte mult! Se vede ca esti o "opera" minunata creata de Tata Iehova! Slavit sa fie Iehova.

Apple Loses Appeal in E-Books Price Fixing Lawsuit, Ordered to Pay $450 Million Fine

The U.S. Court of Appeals for the Second Circuit today upheld a 2013 decision that found Apple guilty of conspiring with publishers to raise the prices of e-books, reports The Wall Street Journal. Apple is now expected to pay a $450 million fine originally set in July 2014 to settle the case, with a majority of that settlement earmarked for consumers as part of a class action lawsuit. 

This is often a tactic used by very large tech companies who have a controlling interest in the market. Microsoft used to strong arm computer OEMs to include Windows on all hard drives being sold (through conditional discounts / penalties), Amazon has been accused of the same with books, and more recently Apple was again at it with the launch of their music streaming service.

10 Industrial Uses for Coke Which Prove it’s Not Fit for Human Consumption

The acidity of Coke has led many to question the toxicity of the product, relating to long-term human health, as its pH rating is only one point higher than that of battery acid.

In a study sponsored by the National Heart, Lung and Blood Institute, researchers found that individuals who consumed at least one soda a day had a 44% higher risk of developing metabolic syndrome during the four-year study.

Those who drank at least one soda per day also had:
- a 31% greater risk of becoming obese;
- a 30% higher risk of having a larger waistline;
- a 25% higher risk of developing high blood triglycerides or high blood sugar;
- a 32% greater risk of having low levels of good cholesterol;
- a trend toward an increased risk of high blood pressure.

In a separate study, it was revealed that people face a 48% increased risk of heart attack or stroke when consuming one or more sodas per day, as compared to those that don’t drink it every day or at all.

+Eben van Ellewee Exactly. Coke pH is right about the same as most lemon juice and vinegar pH. We hear all the time about how healthy they are and how nutritious it is to consume.
All 3 are used for industrial solvents, yet we complain about consuming only 1 of them for their acidity and the other 2 we praise. 

Just don't consume too much, and be sure to drink a couple glasses of pure water per non-pure water drink and you should be good.

Highway Noise Barriers Generate Solar Power

Highway noise can be a nuisance. Highway noise barriers can be hideous.

Now researchers at Eindhoven University of Technology have a found way to make highway noise barriers not only more beautiful but also function as solar power generators.

Initial tests show that .62 miles (1 kilometer) of the barriers could supply electricity to 50 households for a year or supply an electric car battery with power enough to drive 560,000 miles (900,000 km).
Beautiful barriers also function as solar power generators. Continue reading →

Eskom a water guzzler, study finds

Eskom’s battle to keep South Africa’s lights burning is also draining one of the country’s most critical resources – almost 4 000 million litres of extra water each year.

A new joint report by the Water Research Commission and the University of Pretoria warns that mothballed Eskom power stations that have been reactivated in recent years to meet the power crisis are guzzling unsustainable volumes of water.

The new study, summarised in the commission’s latest Water Wheel magazine, suggests that three of the country’s oldest power stations (some dating from 1966) have increased Eskom’s water use significantly and this will be unsustainable unless they are decommissioned as soon as the new Medupi and Kusile power stations come into service.

Bring on solar and wind power generation.... not only quicker to commission, but may less impact of air pollution and water resources...

Yawls: Let Your Webcam Adjust Your Laptop Screen Brightness in Ubuntu/Linux Mint

Yawls stands for Yet Another Webcam Light Sensor, it is a small Java program created for Ubuntu. It adjusts the brightness level of your display by using the internal/externel webcam of your notebook as an ambient light sensor, that uses the OpenCV Library and is designed to save energy of your laptop battery. Yawls can also be used from command line interface and run itself as a system daemon, twice a minute it runs and adjusts the brightness of the notebook screen with reference to the ambient brightness.  The interval time can be adjusted from GUI or from config file if you are using CLI version.

It also has face detection option which can be useful if you sit in a dark room,  yawls can adjust screen brightness as per your needs.

Cracking the Code: U.S. House of Representatives Allows Use Of Open Source Software

As the executive branch of the United States government quietly works on creating an official open source policy, the legislative branch is also moving into the 21st century: Open source software is now officially permitted in the U.S. House of Representatives. That means software developed in the People's House with taxpayer funds will eventually be available to the people. According to the nonpartisan OpenGov Foundation, there will soon be an Open Source Caucus in Congress.

The official policy received support and praise from representatives on both sides of the aisle, as well as open government advocates.

“I’m glad that the House of Representatives has finally opened the door to open-source software,” said Rep. Blake Farenthold (R-Texas). “For over a decade, individual coders and businesses around the country have been working with open source software because of cost savings, productivity gains and the ability to modify the code to meet specialized needs. It’s past time that taxpayers see the same benefits."

Members, committees and staff can now use official resources to procure open source software, participate in discussions about open source software online or contribute improvements to software under an open license.

Kilner Butter Churner - Make your own butter the old fashioned way

The Kilner butter churner offers everyone the easy way to make their own homemade butter, and makes a stylish addition to any kitchen. Simply place whipping cream into the butter churner, turn the handle, and in as little as ten minutes you can enjoy fresh and delicious tasting butter. Included within the set is easy to follow step by step instructions as well as a selection of recipes. 10-1/2 inches high by 4-1/3 inches wide.

The Kilner business was first established by John Kilner in the 1840's in England. Initially producing glass bottles and jars, it was towards the end of the 19th century when the original Kilner Jar was first invented. The original Kilner jar is as much-loved and successful now as it was 120 years ago. Its long-lasting popularity is owed to its distinctive pressure seal and iconic design. Put simply, households all over the world trust it to successfully preserve and pickle their fruit and vegetables. In the 1900's, Kilner presented its innovation as 'the original and the best, all other brands are substitutes', a claim which remains relevant today, and is a testament to its impressive heritage.

Palestinian man overcomes Gaza energy cuts with affordable DIY solar ovens

Bashir is well trained in the field of renewable energy, having earned an M.Sc at the University of Pretoria in South Africa. After graduating, he worked for many years for the Palestinian Agriculture Ministry and is now employed by a construction materials company. Though the construction business in Gaza keeps Bashir occupied, he still manages to find time to pioneer resilient technologies to help his community.

Bashir’s solar oven cooks slowly but effectively. “This oven is better than an electric or gas oven,” says Bashir. “It uses natural energy that doesn’t cost anything and is available in Gaza year-round. Solar cooking helps keep the flavor and quality of the food, and it never burns, because the sun is in constant motion”. Inside the oven, temperatures can reach up to 284 degrees Fahrenheit. “You can make everything in this oven, except tea and coffee”, says Bashir. Because of his oven’s efficiency, Bashir needs only one tank of cooking gas per year.
Khaled Bashir of Deir al Balah in the Gaza Strip has constructed an effective solar oven that takes advantage of Gaza’s solar resources - regardless of the political climate.

What Additives Look Like Before They End Up in Your Food

If you’re eating a processed food, chances are it includes at least one ingredient derived from corn—subjected to acid treatments and various biological tweaks to break the kernel down into different starches and sugars. Here, we see cornstarch, modified cornstarch, maltodextrin, dextrose, corn syrup, and high-fructose corn syrup...but all the possible derivatives of corn number in the hundreds.

Shellac, also known as confectioner’s resin or candy glaze, is a colorant and preservative made out of—hold on to your hats—a resinous excretion called lac, released by the insect Laccifer lacca. The bugs eat tree sap and process it, secreting a waterproof tube of resin that producers harvest and process it for use as a natural plastic for candy and other foods that need a thin, protectant waxy coating. 
Companies have been pulling artificial colors and preservatives out of their formulations. Here's what they look like.

Afrihost ADSL problems acknowledged - Improvements Promised

A lot of people have been complaining of late about the network latency and speeds. The CEO is promising some substantial improvements which will arrive in about two weeks in the form of a proof of concept for clients to test out:

"Over the next few weeks, we’ll be launching two different proof of concepts for this new network. Both proof of concepts will be fundamentally different in the way they work and we'll be working day and night to make sure we get everything right so that we can eventually settle on the best option to move forward with."

"The really great news is that we are going to be asking for your feedback to help us make the decision. We are going to be giving as many clients as we can the opportunity to test drive the networks and then give us feedback on their experience. However, given the fact that they are a proof of concepts, they are much smaller networks, so initially the amount of clients allowed on to test will be limited."
