What is your favorite Linux distribution?
Of all the many questions you might ask an open source enthusiast, none may evoke quite the passionate response as asking which distribution they prefer. People choose a distribution for many reasons, from look and feel to stability, from speed to how it runs on older machines, from the pace of updates to simply which offers the packages they need. Whatever the reason, with so many distributions available, asking which one you use can be seen as ...

How to sell your Bitcoin Cash for real cash in South Africa

How to sell your Bitcoin Cash for real cash in South Africa

With South Africans currently searching on Google for the term "Bitcoin" more than any other country, it may be a good time to post this now. The article explains how to buy Bitcoin for real cash (and visa versa). Exchanges such as Luno will you allow to buy Bitcoins using your local SA bank such as Nedbank, Capitec, etc.

One tip is you had better consider where you keep that Bitcoin. You want to be sure it is a reputable place or otherwise download it to an offline wallet on your computer like Exodus (and back that up because if your drive crashes there goes your Bitcoin).

Think you understand healthy eating? Here’s why you might be wrong

Think you understand healthy eating? Here’s why you might be wrong

“Twenty years ago, I think we knew about 10% of what we needed to know [about nutrition]," said Dariush Mozaffarian, Dean of the Tufts Friedman School of Nutrition Science and Policy. “And now we know about 40% or 50%.”

The researchers suggest that the differences in opinion are most likely due to the fact that scientists are better informed about current food trends, whereas consumers are more susceptible to the claims of food marketers.

Despite confusing data on what is classified as healthy and unhealthy, the overall opinion on the healthiest type of diet was “Mediterranean”; with 25% of nutritionists choosing it.

Advocacy groups push Portugal to use open source to stop losing control over its digital assets

Advocacy groups push Portugal to use open source to stop losing control over its digital assets

To stop losing control over its digital assets, the Portuguese government should make a sincere move to free and open source software, the country’s open source trade group ESOP says. The business association is not convinced that Portugal’s new ICT strategy, published in July, will help.

Increasing the use of open source software solutions in public administration is one of the many measures set out in Portugal’s new ICT strategy. The aim is similar to those of other EU Member States, ESOP told Open Source Observatory (OSOR) by email: “Portugal is aligned with the majority of the EU by stating that it needs to expand its use of open source.”

However, public administrations in Portugal and elsewhere are doing the opposite, ESOP told OSOR: “European governments are less and less in control of their digital assets, as they continue to use proprietary ICT, including cloud solutions.” The lack of commitment to open source is hampering the growth of an independent European software industry, the trade group says.

In a world gone Banting mad, a butter shortage hits South Africa

In a world gone Banting mad, a butter shortage hits South Africa

Last week I could only buy imported Irish butter at PnP (which was delicious) and also noticed that prices have jumped quite a bit. But I'd rather have no butter than going back to margarine.

See https://mg.co.za/article/2017-08-18-00-butter-price-and-supply-going-rancid

Drought, global shortages and over-enthusiastic banting mean the commodity is in short supply

Why Don't Electric Cars Have Multi-Gear Transmissions?

Posted on: Thu, 2017-08-17 - 08:08 By: danie

Why Don't Electric Cars Have Multi-Gear Transmissions?

One of the biggest differences between electric cars and their conventional counterparts has to do with the drivetrain. An internal combustion vehicle has a multi-speed gearbox with numerous ratios; nearly every electric car has a single-speed transmission.

Implicitly, this makes sense. An electric motor delivers its maximum torque at zero RPM. Unlike an internal combustion engine, it doesn't need a system to disconnect it from the drivetrain to allow it to idle while the vehicle is stopped. But there's a more in-depth explanation to be had here, and it's fascinating.

Watch the video that explains it at http://www.roadandtrack.com/new-cars/car-technology/a12019034/why-dont-electric-cars-have-multi-gear-transmissions/

Why Don't Electric Cars Have Multi-Gear Transmissions?
Most electric cars have a single gear ratio. You probably understand the basic reasons for this, but the math is still super fascinating.

It’s harder than you think to get your smartphone stolen in South Africa

f there’s one thing you can count on in South Africa, it’s that if you need something stolen, you don’t have to try hard to make it happen, right?

Wrong.

It turns out our countrymen are honest and caring people, and my efforts to get a smartphone stolen multiple times failed miserably.

How to Install Linux in Windows With a VMware Virtual Machine

How to Install Linux in Windows With a VMware Virtual Machine

You’ve tried Linux from a live CD. Now you want to install it, but you’re unsure about dual booting. The sensible option is to install your chosen Linux operating system in a virtual machine (VM).

This means that a software environment replicates the conditions of a hardware environment: a personal computer. The environment is based on the hardware of your physical PC and limited only by the components within. For instance, you couldn’t have a virtual four core CPU on a processor with two cores.

However, while virtualization can be achieved on many systems, the results will be far superior on computers equipped with a CPU that supports it.

Several virtualization tools are available that make it easy to install Linux operating systems (OS) and there are many in Windows.

VMware produces the most accomplished virtual machine applications. Let’s find out how to install Linux in Windows with VMware Workstation Player.

I certainly find VMware Workstation to be more refined and better integrated on my MacOS than Oracle's VirtualBox.

Public charging stations: Can South Africa support electric cars?

Public charging stations: Can South Africa support electric cars?

Around the world, support is growing for electric cars. Automakers are delivering more electric models with longer range and lower prices, such as the Chevrolet Bolt and the Tesla Model 3.

China has set aggressive targets for electric vehicle sales to curb pollution; some European countries aim to be all-electric by 2040 or sooner.

Those lofty ambitions face numerous challenges, including one practical consideration for consumers: If they buy electric cars, where will they charge them?

In South Africa, there are three fully electric vehicles on sale in the market: BMW's i3 and i8, and the Nissan Leaf. Various manufacturers have several battery-hybrid vehicles available locally, including Volvo and Mercedes-Benz.

Nissan South Africa says: "In Gauteng there are more than 90 EV charging stations. These are available at shopping centres and office blocks. "There are 9 Nissan dealerships with EV charging stations, 7 of them also sells Nissan LEAF. We also have the memorandum of understanding (MOU) with BMW where we can tap into each other’s charging network. Cape Town is also catching up with various charging stations installed across the city."

Bottom line is SA has a very long road ahead of itself still for EVs and with little government incentive at this stage, it is not likley to pick up very soon...

Italian-style coffee could halve the risk of prostate cancer

Italian-style coffee could halve the risk of prostate cancer

Key takeaways here are that this is about caffeinated coffee and the traditional Italian style of preparation (boiled under pressure, no paper filters). This means a 'Moka pot' or in SA we refer also to percolated coffee. See how this coffee is prepared at https://bluebottlecoffee.com/preparation-guides/bialetti-moka-pot and more on Moka pots at https://en.wikipedia.org/wiki/Moka_pot.

See http://www.medicalnewstoday.com/articles/317178.php

Italian-style coffee could halve the risk of prostate cancer
Drinking at least three cups of Italian-style coffee every day may lower men's risk of prostate cancer by more than 50 percent, new research suggests.
