WIkimedia for Cape Town

Cape Town has won the bid to host the 14th annual Wikimania conference, an annual gathering of volunteers from around the world to celebrate Wikipedia and the Wikimedia projects.

Published

Attendees will be made up of members of the global Wikimedia movement, including those who volunteer their time to edit and improve Wikipedia articles, create bots, or organise events and projects to draw more content onto Wikipedia and the Wikimedia projects. Other open knowledge  advocates will also attend, along with local academics, teachers, heritage specialists, and interested stakeholders.

Across more than 70 sessions, attendees will work to bring the conference theme: Bridging knowledge gaps; the Ubuntu way forward, to life by ensuring that some of the fundamental principles of the Wikimedia movement are contextualised within the rapidly evolving internet narrative.

Confirmed speakers include internet geographist Dr Martin Dittus, who will be speaking on economic development, labour, power, participation, and representation. Joy Buolamwini, a noted Artificial Intelligence expert fighting to remove bias in machine learning, and Professor Sean Jacobs whose focus areas includes trends in digital culture are also invited thought leaders at the conference.

“Our vision is a world in which every single person can freely share in the sum of all knowledge. We believe that knowledge belongs to everyone, and that people from diverse backgrounds should be empowered to participate in the collaborative creation of knowledge,” said Katherine Maher, Executive Director, Wikimedia Foundation.

Wikimedia is also looking to expand its non-Western topics, where there is still not enough locally relevant content about Africa, particularly that which is gathered from African perspectives or shared in African languages. The same could be said for indigenous knowledge and local knowledge from many places outside the Global North, much of which is still missing. South Africa has active Afrikaans and isiXhosa Wikipedia editions, but most of the other indigenous languages from the continent are either missing or do not have regular contributions on Wikipedia.

Challenges with software localisation, the structure of data, and even the forms of knowledge that Wikimedia has defined as “verifiable” (text-based, rather than oral, for example) are some of the issues the movement is grappling with as it moves actively towards incorporating more diverse kinds of knowledge within Wikipedia and the Wikimedia projects.

This year’s Wikimania conference will take place at the Southern Sun, Cape Sun Hotel. Wikimania 2018 is co-organised by Wikimedia South Africa, the local Wikimedia affiliate organisation of South Africa, and the Wikimedia Foundation, the non-profit that supports the Wikipedia and other free knowledge projects.

Wikipedia is a collaborative collection of knowledge that is open for anyone to edit.  Today Wikipedia is available in more than 45 million across nearly 300 languages, and is read more than 15 billion times every month. Volunteer editors from around the world, or Wikipedians, come together to write and update Wikipedia articles in real time, collaborating to ensure that information is neutral and based in reliable sources. Each month, more than 200,000 people edit Wikipedia.

The Wikimedia Foundation is the nonprofit organisation that supports Wikipedia, the Wikimedia free knowledge projects, and its mission of free knowledge for every single person.

The myths of microwaves

Published

on

We all know microwaves make cooking a breeze and it helps save those minutes, we rarely have enough of these days. However, some people do have those lingering doubts about whether microwaving food destroys nutrients or that it emits harmful radiation. However, the truth is a lot more comforting and positive.

“The microwave makes life so much easier,” says Tracy Gordon, Head of Product – Home Appliances at Samsung South Africa. “It’s human-centred technology at its most helpful. The Samsung Hotblast for example, has revolutionary functions, which are tailor-made to create fast, tasty and healthy meals in minutes.”

A recent article by Harvard Health Publishingclaims stated that “microwave ovens cook food using waves of energy that are remarkably selective, primarily affecting water and other molecules that are electrically asymmetrical. Microwaves cause these molecules to vibrate and quickly build up thermal (heat) energy.” The article debunks two common myths about microwaving food.

Myth 1: Microwaving kills nutrients

Whether in a microwave or a regular oven, some nutrients, including vitamin C, do break down when exposed to heat. However, the fact is, cooking with a microwave might be better when it comes to preserving nutrients because it takes a shorter time to cook. Additionally, as far as vegetables go, cooking them in water robs them of some of their nutritional value because the nutrients seep out into the cooking water,” states the report by Harvard Health Publishing. According to the World Health Organisation (WHO), food cooked in a microwave oven is as safe and has the same nutrient value, as food cooked in a conventional oven.

Myth 2: Microwaving food can give you cancer

The American Cancer Society (ACS) says that microwaves do not make food radioactive. Microwaves heat food but they do not change the chemical or molecular structure of it. In fact, there is absolutely no evidence that microwaves pose a health risk to people when used appropriately, the organisation added.

With those myths well busted, it’s comforting to know one can make full use of the convenient kitchen appliance. And when the time comes to use a microwave to heat up a tasty meal in no time, one can trust the Samsung Hotblast to do the job. The HotBlast has multiple air holes blowing out powerful hot air, which reduces cooking time. Samsung claims the Slim Fry technology ensures that food is perfectly crisp on the outside and delicious and juicy on the inside. Additionally, this versatile microwave has a wider grill, making it easier to brown food fast and evenly. The turntable is wider, measuring 345mm, making it possible to prepare bigger portions of food. And with its Eco Mode power, it significantly reduces energy consumption with its low standby power. Its intelligent features and stylish design makes it very useful and as we now know – a safe, healthy way to enjoy a meal.

New BMW 3-series ushers in autonomous future

The new BMW 3-series is not meant to be an autonomous car, but it is so close, ARTHUR GOLDSTUCK discovers.

Published

on

It was not meant to be a test-drive of an autonomous vehicle. But the Driving Assist button on the steering wheel of the new BMW 330i was just too tempting. And there I found myself, on Sir Lowry’s Pass near Cape Town, “driving” with my arms folded while the vehicle negotiated curves on its own.

Every 10 seconds or so, yellow or red lights flashed to alert me to put my hands back on the wheel. The yellow lights meant the car wanted me to put my hands on the wheel, just to show that I was in control. The red lights meant that I had to take over control from the artificial intelligence built into the vehicle.

With co-driver Ernest Page, we negotiated a major highway, the bends of Sir Lowry’s pass, and the passes of Hell’s Heights (Hel se Hoogte) above the Cape Winelands.

As the above video of the experience reveals, it can be nerve-racking for someone who hasn’t experienced autonomous driving, or hasn’t been dreaming of testing it for many years. For this driver, it was exhilarating. Not because the car performed so magnificently, but because it tells us just how close true autonomous driving really is.

There was one nervous moment when the autonomous – or rather, Driving Assist – mode disengaged on Hell’s Heights, but fear not. A powerful sense of responsibility prevailed, and my hands hovered over the steering wheel as it took the curve. Assist disengaged, and the car began to veer towards the other side of the road. I quickly took over, and also sobered up from the giddiness of thinking I was already in the future.

In reality, Driving Assist is part of level 2 of driving autonomy, as defined by the Society of Automotive Engineers. A presentation on the evening of the test drive, by Edward Makwana, manager of group product communications at BMW Group in South Africa, summed up the five stages as the driver having Feet Off, Hands Off, Eyes Off, Mind off, and finally, only being a Passenger.

However, the extent to which the hands-off mode of Driving Assist mimics self-driving, and easily shows the way to eyes-off and mind-off, is astonishing.
