Burkina Faso’s 35-year-old President Ibrahim Traore says Africa’s story has to change.
Ibrahim Traore accused African leaders of “beggary”
“My generation does not understand this: how can Africa, which has so much wealth, become the poorest continent in the world today and why do African leaders travel the world to beg?” - Ibrahim Traore

ROASTERS: Understanding the Rate of Rise
Rate of Rise (RoR) measures the speed at which the temperature of the coffee bean rises during the roasting process. It is a crucial metric that indicates the rate at which the beans absorb heat from the roasting machine. It is essential to distinguish RoR from the actual temperature of the bean. While the temperature measures the current state of the bean, RoR measures how quickly that temperature changes.
Roasters gain valuable insights into the roasting process by analyzing the RoR data plotted on a roast graph. Roast curves visually represent the temperature changes over time. RoR provides a dynamic view of the bean's temperature increase, enabling roasters to make timely adjustments and achieve consistent roast profiles. It empowers them to maintain control, anticipate changes, and avoid potential mistakes that could impact the flavor and quality of the final cup of coffee.
Calculating the Rate of Rise
Modern roasting technology, accompanied by specialized software, simplifies collecting RoR data. These software tools enable roasters to capture temperature data at different intervals, such as 1, 5, 10, 15, 20, 30, or 60 seconds. The choice of the time interval depends on various factors, including the specific roasting machine and the desired level of precision.
When selecting the appropriate time interval, it is crucial to consider the trade-off between precision and noise. A shorter interval provides greater accuracy but can introduce more noise into the data due to system interference and sensor fluctuation. This noise may lead to a graph with numerous spikes, making it challenging to analyze. On the other hand, a longer time interval produces a smoother curve with fewer spikes but at the expense of finer details.
For people using roasters with high idle noise or system interference, it is advisable to opt for a higher time interval, such as 60 seconds, when calculating RoR. This choice results in a smoother roast curve that is easier to interpret. However, shorter time intervals can be chosen for more precise analysis for those using advanced roasting technology with minimal noise.
If you are starting in coffee roasting and cannot access specialized software, you can still calculate RoR manually. The process involves measuring the temperature at regular intervals, such as every 30 seconds or every minute, and calculating the temperature difference between consecutive readings. This simple approach lets you gain insights into the RoR during roasting.

A new ocean is forming in Africa along a 35-mile crack that opened up in Ethiopia in 2005. The crack, which has been expanding ever since, is a result of three tectonic plates pulling away from each other.
There are still some big unknowns, including what is causing the continent to rift apart. Some think that a massive plume of superheated rocks rising from the mantle beneath East Africa could be driving the region’s continental rift.
Each plate boundary in the Afar region is spreading at different speeds, but the combined forces of these separating plates is creating what’s known as a mid-ocean ridge system, where eventually a new ocean will form.
The three plates are separating at different speeds. The Arabian plate is moving away from Africa at a rate of about 1 inch per year, while the two African plates are separating even slower, between half an inch to 0.2 inches per year.

A woman left the husband with children when conditions were bad and went to Saudi Arabia to work for a better life. She kept sending her salary to the husband so that they could build a house and have something for the family.
The husband used the money to build a house with another woman who he married and also to pay the bride price for the other woman.
She came back hurriedly when someone shared with her a photo of the husband being enjoying life with the other woman.

"£5M net worth ? He's actually handsome" - Female football fans react to Krepin Diatta's net worth 🤗😳🇸🇳
After Senegal's defeat against Cote d'Ivoire at AFCON 2023 yesterday, Senegal football star, Krepin Diatta for two reasons.
1. He accused the referee of favoring Cote d'Ivoire in officiating.
2. His looks, many people started commenting about his looks and after a popular sports blog published his net worth to be £5M, many women started crushing on the married man.
Krépin Diatta earns £36,000 per week, £1,872,000 per year playing for Monaco & Senegal national football team.
Krepin Diatta didn't chose to be this way, we should be cautious and respectful how we react to people's looks 🙏
But ladies 🤔🤔🤔🤔🤔

“There are people in this Ugandan Parliament who claim to love President Museveni more than Dr.Kizza Besigye who treated him when they were fighting in Luweero. Even if you are one of them, you cannot justify the President keeping 266 vehicles at his residence (State House) & 400 vehicles under his office yet the total number of ambulances in Public facilities is 178. The convoy alone is 69 vehicles," Kira Municipality MP, Ibrahim Ssemujju Nganda
