Frank Rheins, the prince of "Nigerian" likes.
I just want to ask the Kenyan Engineers one thing: Can you come to California and show us how to make a wildlife path through a freeway? The Government here spent over a 100 million on one, but the animals don't yet have a way to use it, because more money is needed to finish installing on and off ramps.

Engineers in Kenya built a tunnel underneath a highway to reconnect a centuries-old elephant migration route that had been cut off by new construction. Then they had to figure out how to get the elephants to actually use it. Workers lined the entire inside of the concrete tunnel with fresh elephant dung to create a familiar scent trail. A bull elephant named Tony followed it through first, then led his entire herd to the other side. The tunnel is fourteen feet high. The migration route is hundreds of years old.

How knowledge grows & spread to commerce is weird. 2014, did Msc and one of the most interesting courses was AI & ML. Learnt neural networks and fuzzy logic in quite some detail. Finding a real world application then was difficult . Just a decade later it's all over the place!

One year and one month since I switched from Tata to CFAO. In the one year as a sales agent, I have already done in sales, thrice the number of vehicles I did with Tata where I worked for 3 years. This God!!! 🙏🙏🙏🙏

Ill give you an answer, In the latest world weve turned everything to content-in extremities we want to monetize it Most go for bikes just because its photo friendly. Two hikes later they form a whatsapp group and want to make money planning the hikes. Dead are hobbies that you could just do yourself and friends for fun. The authenticity of it -for most ,is gone
Sasken@Sasken_T

Ati you want to go running, you have to join a running club, you want to go hiking, you have to join a group, heck you want to go cycling, you have to join a cycling group. What the fuck happened to doing things alone? People don't value solitude anymore? Lame ass niggas.

@Sasken_T Finally someone said it. What is with people not wanting to do things alone? That's how the clubs are made, you start running alone, someone else does too, yall meet and now it's a community. Everyone just wants a community that's already been formed😂

FERDINAND OMONDI@FerdyOmondi·
Kenya’s rush into a 2,000MW nuclear plant in Siaya is a historic mistake in the making – economically, environmentally, and strategically. First, context. Kenya already gets about 85–90% of its electricity from clean sources: geothermal, hydro, wind and increasingly solar. We are a global poster child for clean power without nuclear. Our main challenge isn’t a lack of clean options. We aren’t planning and using what we have well enough. So why gamble billions on the most complex, riskiest option on the menu? A single 2,000MW nuclear plant is one of the largest, most expensive projects in our history. These plants are notorious for cost overruns and delays in far richer, more technically advanced countries. If it runs late (very likely) or goes over budget (almost guaranteed), someone has to pay. That “someone” is Kenyan taxpayers and electricity consumers. We risk locking ourselves into decades of high tariffs or more public debt to service a mega‑project we didn’t actually need. Meanwhile, the opportunity cost is massive. For the same money, Kenya could add thousands of megawatts of geothermal, wind and solar across multiple counties, plus storage and transmission to stabilise the grid. Geothermal alone, in the Rift Valley, can provide 24/7 baseload power without importing fuel – and we’ve already shown we know how to do it. Wind in Turkana, solar in the north and east, small hydro, battery storage: these are proven, modular, quicker to build, and spread economic benefits more widely than one giant plant in Siaya. Then there’s the risk profile. Nuclear accidents are rare, but when they go wrong, they go very wrong and last for generations. Putting a first‑ever nuclear plant on Lake Victoria, which supports millions of people across several countries, is a huge regional gamble. Even “minor” incidents or perceived risk can devastate fisheries, tourism, and local livelihoods. Radioactive waste is a 100‑year question in a political system that struggles to manage five‑year projects without scandal. Do we really trust our current institutions to run a flawless nuclear safety culture for the next century? Governance is the elephant in the room. Nuclear is the kind of project that attracts opaque deals, expensive foreign contractors, complex technology transfer promises, and huge procurement contracts. In a country where big infrastructure routinely raises questions about corruption and value for money, adding nuclear’s complexity is like pouring petrol on a smouldering fire. Once we sign, we are locked in – to a vendor, to a technology, to a repayment schedule – regardless of how our economy or technology options evolve. Strategically, it also makes little sense. The world is moving towards flexible, distributed, renewables‑heavy systems supported by storage and smart grids. Nuclear is the opposite: big, centralised, inflexible units that must run almost all the time to be economical. On a grid like Kenya’s, where demand is still growing and industrialisation is uneven, dropping 2,000MW of inflexible baseload can actually complicate balancing, especially when we add more variable wind and solar. We risk building a system that is technically elegant on paper but financially and operationally brittle in reality. Kenya’s climate and geography give us an embarrassment of renewable riches: untapped geothermal reservoirs, some of the best wind regimes on the continent, abundant solar irradiation, and room for regional power trade. Instead of doubling down on what works and scaling it smartly, we are flirting with the most capital‑intensive, politically risky, institution‑demanding technology available. It’s like bypassing a field full of ripe maize to plant a single, exotic crop we’ve never grown before, which only matures if the weather is perfect for 20 years. If our goal is cheap, reliable, climate‑friendly power that supports jobs and industry, the answer is to go deeper on what we’re already good at: – Aggressively expand geothermal as firm baseload. – Add more wind and solar, especially near demand centres. – Invest in storage, transmission, and regional interconnectors. – Fix governance, planning, and utility finances so that Kenyans actually feel the benefit on their bills. Nuclear might have a place someday in a much larger, richer, more industrialised Kenya with rock‑solid institutions. But right now, when we are already at 85%+ clean power and sitting on huge untapped renewable potential, a 2,000MW nuclear plant is not visionary at all. It’s a high‑risk distraction. Our focus should be on making Kenya the first truly renewables‑powered industrial economy in Africa, not a test case for big nuclear on Lake Victoria.

Ruto: Kenya plans to commence construction of a 2,000MW nuclear power plant in Siaya County next year, with commissioning of the project expected in 2034. To the people of Siaya, I invite you to be partners in this journey.

Hello @KenyaPower_Care you guys are thieves and criminals and I seriously cannot stand you all. You’re a criminal enterprise. I was conned by a Kenya power staff, I agreed to start the process again by applying and it’s been two weeks now, I asked for the quotation and they tell me to pick it up at their office even though the process is online, I send someone and they’re saying it’s not ready even though the person that quoted it says it’s ready. Their customer service is the worst I have ever seen. @KenyaPower is a criminal enterprise!!!! Bunch of criminals!!!

KRA plans to make it mandatory for all businesses, even small traders, to register for VAT. This means businesses and small traders will add 16% tax, which will make prices of goods go up.

Terafab First, the Advanced Technology Fab— where new manufacturing technologies are proven out. Think of it as the prototype line. Then Terafab itself: By a wide margin, it will be the largest factory in the world. Let's guess at sizing: Quick math tying it to the 1 TW target + 250W AI5 chips 1 TW = 1,000,000,000,000 watts of AI compute capacity. Each AI5 chip draws ~250W Chips needed annually for 1 TW scale: 10¹² W ÷ 250 W/chip = 4 billion chips/year. To produce 4 billion AI5 chips per year (the volume needed for 1 TW of compute at 250 W/chip), a Terafab-scale facility modeled on current TSMC fabs would require 3,000–5,000+ acres or land and 280–350+ million square feet of total building/floor space. Obviously innovations must be applied. I'd hazard a guess at a 100 million sq ft size factory.
Elon Musk@elonmusk

No, that’s just the little advanced technology fab, where we will be iterating on chip designs. We couldn’t possibly fit the Terafab on the GigaTexas campus. It will be far bigger than everything else combined there. Several locations for Terafab are under consideration. It needs thousands of acres and over 10GW of power at full scale.

The #FootballKE Advocate
Jana kuna mtoi wa jirani nilipata akiwa solo nje na bike yake (those tu bikes with them extra 2 wheelers). He doesn’t know how to seat & balance on it (he’s probably 3 yrs at most). He kept repeating “bike..” to me. Nilimweka kwa hiyo bike tukapiga ma lap kiasi. He was all quiet but the moment I started pushing it at a faster speed and making sharp corners, alikuwa ana nice dedli. Did that for like 5 mins ikabaki nisonge cause I was stepping out kuenda game ya Gor. It really did feel great making his day..🥹

🚨Architects are going to hate this. Someone just open sourced a full 3D building editor that runs entirely in your browser. No AutoCAD. No Revit. No $5,000/year licenses. It's called Pascal Editor. Built with React Three Fiber and WebGPU -- meaning it renders directly on your GPU at near-native speed. Here's what's inside this thing: → A full building/level/wall/zone hierarchy you can edit in real time → An ECS-style architecture where every object updates through GPU-powered systems → Zustand state management with full undo/redo built in → Next.js frontend so it deploys as a web app, not a desktop install → Dirty node tracking -- only re-renders what changed, not the whole scene Here's the wildest part: You can stack, explode, or solo individual building levels. Select a zone, drag a wall, reshape a slab -- all in 3D, all in the browser. Architecture firms pay $50K+ per seat for BIM software that does this workflow. This is free. 100% Open Source.
