Where is Africa’s ‘Internet’?

Posted on 2 min read

Africa has made great strides in getting connected to the internet. There are 453,329,534 internet users, which translates to an  internet penetration of 32.5%. This figure is steadily growing, and we are steadily shaking off the tag of ‘the dark continent.’

But where is Africa’s data stored and processed? Many websites registered under Africa’s ccTLD, that is names like .ke, .ng, .tz, .za etc, are hosted in Europe and America. This is besides a similar number of other gTLD domains such as .com and .net, which are owned by Africans, but hosted abroad too. This means that many of the websites that are being accessed by Africans, are actually located in other continents.

One can see why most of these sites are located elsewhere. As of December 2018, US accounted for 40% of all Data Centers in the world. Africa does not rank here, and one can conclude that the number of Data Center is way much smaller compared to other continents. This is why many African sites will continue to be hosted in other continents. The cost of hosting also plays a major role with collocation in African Data Centers costing more than double the cost in the US and Europe.

Does this pose a problem? Yes, there is a big problem. The two main problems include capital flight, and latency. Africans end up spending billions of money on hosting abroad, money which could impact the economy if injected into respective countries. It has been reported that Nigerians alone spend about 60 m USD (6 billion KES) on paying for web hosting abroad. Other African countries follow a similar trend, and the money that could be building Data Centers in Africa, improving terrestrial fiber networks or even building local companies, is being pumped into developed countries.

The second problem involves latency. Although connectivity in Africa has greatly improved with several submarine fiber cables going around Africa and a vast network of terrestrial fiber, one of the main bottleneck that impacts user experience is latency. Latency refers to the time it takes for data to be transferred from the server to the user, and this time is quite high due to a physical distance between users in Africa, and servers in other continents. This is because it takes about 60 times longer to access data from Europe, than it takes when data is locally hosted. If you are in Kenya, you can test this by accessing the eCitizen website which is hosted locally, any other website that is hosted abroad.

Of course, a difference of less than a second does not hurt anyone, many think. But, this is not true. A lot of man-hours are wasted while people wait for pages to load. Money is spent on leasing international links to deliver this data, and once the world makes the leap to 5G where bandwidth will not be the limit, latency will be bottleneck. We must reverse this now.

Deliver us from Instant hot shower

Posted on 2 min read

We all love showers, and we love them hot, or more precisely, warm. Instant hot showers are loved for just that. In the age where we want all things instant, instant hot water shower is the instantest of all. Just a flip of the switch and one enjoys water which is not cold, at least.

But this dearly loved device is a scam. For some reasons, I never get to understand what goes inside the head of the shower. I heard someone who used it for the first time claim that the water was both hot and cold at the same time. I had never made such an observation, but I immediately agreed that such a phenomenon exists. Instant hot showers have the following shortcomings:

  • Risk of electric shock. Faulty wiring would deliver 240 Volts down your body. This is rare, but I have seen it happen.
  • Water is both hot and cold. You have to solve a complex matrix in order to maintain water at the same temperature.
  • It is a major power guzzler. Instant shower can account up to 50% of all electricity costs in a small household.
  • It cannot work under low pressure. Water at low pressure may lead to the shower being too hot to use, or worse, the shower might not heat.
  • Short life span, especially if it is a fake brand.
  • Their use might be coming to an end, as the government might consider banning them. This is according to a ministry of energy consultant.

One solution to instant water heaters is use of solar water heaters. These have the capacity to heat considerable volumes of water at very low costs, and their costs is cheaper in the long run. Not only are they maintenance free, but they also can deliver high volumes of water since they have water reservoirs attached.

In Kenya, solar water heater with a capacity of 200 litres cost approximately KES 50,000 (USD 500). Once installed on the rooftop or any other convenient place, they can serve effectively for up to 20 years. Their water tank is insulated to minimize heat losses, enabling them to store hot water for up to 72 hours. In Kenya, there is the Solar Water Heating regulation that requires all buildings with a consumption of more than 100 l of hot water per day.

Wondering what happens during the rainy season or non- solar day? No problem. These solar heaters have a secondary electrical heating element, which allows water to be heated directly from the mains.

Automatic Number-Plate Recognition

Posted on 1 min read

Automatic number-plate recognition is a technology that uses optical character recognition on images to read vehicle registration plates. This simply means, a camera takes a picture, and a software analyzes the picture to identify a vehicle, then identify a number plate in the vehicle, and read that number plate. This allows for a machine (or any system) to identify a vehicle on the road, much as a human being can do. In Kenya, this is implemented using CCTV cameras on the roads, or cameras specifically designed for this purpose, such as one used in toll stations.

Applications of Automatic number-plate recognition

  • Tracking stolen vehicles
  • Identifying guest vehicles, hence better visitor management
  • Useful in tracking average speed of a vehicle
  • Traffic engineering design.

Besides these basic uses, there are more applications that can be useful in Kenya. One such would be identifying fake number plates, and cases where two vehicles have been assigned the same number plate. This would have been a major tip off that could have prevented the terrorist attack at Dusit D2 Hotel complex at Riverside drive.

We need to have technology doing more for us. We should have technology telling us that KCN 340E is a blue Toyota Ractis, and even alerting us that two different cars with the same number plates have been spotted.  This way, we shall be a step ahead in identifying crooks before they roam freely in our cities. God bless Kenya.

6 Trends coming to Kenya’s internet in 2019

Posted on 2 min read

Welcome to 2019. We have been told that there are several must have skills, such as time management, adaptability, collaboration, persuasion, creativity, UX Design, People management, analytical reasoning, AI and Cloud computing. Below are 6 trends that will affect the internet in Kenya in the year 2019.

  • Increased access

Smartphones are getting cheaper, cost of connectivity is decreasing, and internet coverage is growing. More people are getting online.

This is good news for a digital economy. Do not miss the train; purpose to be online.

  • Privacy

In 2018, The European Union started implementing the General data Protection Regulation (GDPR). This law is meant to enhance privacy and protect the data of all the European Union citizens. Many countries followed suit, and Kenya already has a Data Protection Bill which is before the parliament and the senate, and its implementation will send ripples in the whole IT industry.
Critics think that the laws will stifle innovation, considering that most tech giants today have risen through an ability to access and process data. We hope this will work to our good.

  • Fake news

Donald Trump has a sensitive nose to fake news, and thanks to him, we all can smell fake news. Unfortunately, it is very hard to detect fake news, and depends on your believes and interest. If you think Kenya is in too much debt, you will likely agree with any news that suggests that Kenya is drowning in debt. If you hate a politician, you will agree with any news that paints him negatively.

With our biased lens, we will not easily identify fake news.

  • Disconnecting/Unplugging

Many people already feel worn out by an overly connected world. We have notifications from our watches, phones, emails, computers, social media, alarms, microwaves, and many other smart devices. The constant blinking, ringing and buzzing of devices can be a productivity killer.

For those who want to unplug, there are a few steps you can take:

  1. Start by turning off unnecessary notifications from your phone. You can set it to be notified of only calls.
  2. Consider uninstalling applications such as social media apps. This makes it harder for you to log in to those sites, hence decreased access.
  3. Set specific time to check notifications, and ignore them at any other time.
  4. At worst, consider deactivating the offending apps.
  • 2022

The year 2022 is 3 years away, but it feels like it is just next door. The internet will be full of 2022 activities, from early campaigns, political alignments, and general news. Wear your helmet.

  • Cybersecurity

This is talked about in hushed tones, because our banks are at risk, our M-PESA balances are at risk, our data is not safe, and even the government is not safe. Socially engineered attacks will continue to affect banks and mobile money platforms, with the Kamiti brigade becoming smarter. Stay safe.

Solar Energy for Small and Medium Sized Households

Posted on 3 min read

Everyone is going solar. Some want to use renewable energy, others want green energy, some want to save the planet, others want to cut carbon emissions, and some simply think it is cool. If you want to join the bandwagon, I will tell you why you should, and why you should not, depending on your needs.

First, there are some very good news about solar energy (In this case, we are talking about Solar Photovoltaic, which involves converting solar energy to electrical energy. There are many other uses, such as solar water heater).

  1. The cost of solar power has gone down, and is on the downward trend. This means that it will keep getting cheaper in the future. Good news.
  2. The cost of storage is also going down, and storage technology keeps getting better. This is important because any meaningful solar installation requires storage.  You can guess why; the sun never shows up at night, and solar panels convert solar (sun’s) energy into electrical energy.
  3. You can now seamlessly switch between mains ac and solar power, meaning that you use solar power when it is available, and switch to mains electricity when necessary.

Who can use solar power?

Solar power is freely available, as long as you can see the sun. This means that if you have a roof, or some grounds available, you can mount solar panel. Any house owner or property owner can install solar panels, but if you are in a rented apartment things may not work good for you, unless if you are a friend to your landlord, or you are influential 😊.

Solar power can be used nearly in every part in Africa, as the sun is a friend to Africa. The Sunshine duration in Nairobi is 6.8 hours in Nairobi, 9.4 hours in Cairo, and 8.4 in Cape Town. In Kenya, the average sunshine duration is 6.9 hours, which means that we have the sun shining almost all throughout the year, with peaks in January. In short, everyone can board!

But,

You need to have your priorities right. If your side hustle is welding steel gates in your house, or running a posho mill, you are not eligible. To put it more accurately, you can consider solar, but your investment will be in millions. Here we are addressing domestic consumers.

Hybrid Solar system diagram

Sample case

If your monthly power consumption is 55 units of electrical power, your electricity bill would be approximately KES 833 in Kenya, or KES 10,000 per year. This could be the following devices running in the house:

  • 100 Watt fridge running full-time
  • 30 Watt TV running for 4 hours per day
  • Two 10 W bulbs running for six hours per day
  • A laptop running for three hours per day
  • Three  15 Watt bulbs running for  4 hours per day

For the above, you would need to have at least a battery capacity of 230 Ah, a solar panel of 262 Watts, and an Inverter of about 300 Watts. This would cost about 75000, exclusive of installation costs. This means that it would take you about 10 years to recover your investment. Solar panels have a long usage life, up to 30 years, while for the battery, you might need to replace it at most every 7 years.

Solar Water Heater

I would want to mention a few things about solar waters heaters because they have one of the easiest application. One of the huge costs in small households is heating water, and adopting one can help reduce your electricity consumption significantly. Read about Solar water heaters in this article.
