There is a concerted effort by rival parties and the press to oust Nigel Farage as leader of Reform. It would be a mistake for Restore Britain to join in. Farage faces scrutiny from the Parliamentary Commissioner for Standards following a Times investigation into his association with “Posh George” Cottrell, and an undeclared £5 million donation from crypto billionaire Christopher Harborne. If found to have broken the rules on reporting gifts, he could be suspended as an MP and face a by-election. The likes of Fraser Nelson and Boris Johnson are salivating at the prospect of sabotaging Reform, replacing Farage with a Tory defector or performing political necromancy for the Conservative Party. Persecution might further endear Farage to the public. It suggests the establishment is afraid of him, and could encourage him to continue his recent strengthening of rhetoric on immigration and anti-white racism. But some in Reform are eager to purge the party of nationalist sentiment. There are already traitors talking to the Observer, detailing their efforts to remove “trigger-happy” Zia Yusuf from his role as Home Affairs spokesman. “Zia’s a big problem,” one said, with others arguing “privately that the use of racial politics was necessary to see off Rupert Lowe’s Restore, but the party ultimately needs to appeal to the centre to have any chance of winning.” With the right on the ropes, it is unwise for Rupert Lowe to promise to “throw everything” at a by-election in Clacton. Restore can’t afford another self-inflicted wound, after weeks of Rupert making needless rhetorical blunders about ethnonationalism and multiculturalism, causing infighting among the base. Joining a witch-hunt would reinforce the narrative that Restore is purely motivated by vengeance against Farage — which is not what most of Restore signed up for.

This One Technique Will Completely Change How You Play Run Defense in #CollegeFootball27 🔥 Ghost Walking is a conservative run defense that helps prevent offensive linemen from pancaking your user and creating explosive runs. How to do it: 1️⃣ Turn your user completely around before engaging the blocker 2️⃣ Wait for the RB to enter your area 3️⃣ Turn back around or dive at the runner to make the tackle Why it works: 🏈 Turning your back prevents the offensive line from triggering a pancake animation on your user. Instead of risking a huge gain every time you shoot a run, you're forcing the offense to consistently earn 3-5 yards at a time. It won't create as many tackles for loss, but if your goal is eliminating explosive runs, Ghost Walking is one of the most reliable techniques you can learn. 🎥 Full breakdown in the video. 📌 Bookmark this and follow Swolosimo for more College Football 27 tips 🔥

Hello! Here are the key updates as of now: 1️⃣ One person has been killed and two others injured as a result of drone attacks on Samara and Novokuibyshevsk, the regional governor reported. The likely target was a petrochemical plant. 2️⃣ A fuel depot in Feodosia and the Gorky oil pumping station in the Nizhny Novgorod region were also hit. 3️⃣ Toxic clouds are hanging over Tuapse, leaving a black residue on animals, cars, and buildings. 4️⃣ Trump stated that, at his request, Iran canceled the execution of eight female protest participants. Iranian authorities say they had not planned to execute them. 5️⃣ In Russia, people born after 2008 may be permanently banned from smoking: the State Duma is discussing a lifetime ban on the purchase of cigarettes and vapes for those born after 2008, similar to the UK model.

Well done to ‘Lower the Flags Shrewsbury’ for their efforts, seen here being pounced on by a couple of Flag Shaggers. One of them (with crazy eyes) using the Ryan Bridge technique of using intimidation, then saying out loud 'I feel seriously threatened', the big girls blowse. Crazy eyes, goes on to pull the scarf from the face of one of the group of litter pickers. The van as you can see was left causing an obstruction on a busy highway. It appears to have the name JC Cars and Commercial’s on it which corresponds with the numberplate JC69CAC or similar. Anyone know them in the North Shropshire area, they may not have the companies permission to use this vehicle or the requisite insurance cover?

A turning point for One Nation and for Australia. For the first time in a regular Senate election, One Nation has secured three seats. That puts us on par with the Nationals in the Senate. This is our best ever federal election result. This didn’t happen by accident. After nearly three decades of standing up for everyday Australians, through abuse, attacks, and attempts to silence us, we’re stronger than ever. Voters are waking up to the truth: One Nation is the party that will fight for true Australian values and everyday Aussies. We’ve been clear from day one: – Scrap net zero and get out of failed global agreements – Cut cost-of-living pressures – from power bills to taxes – Support pensioners and families – Back our farmers, miners and manufacturers – End mass immigration - Restore housing affordability – Support our nation’s industries, more jobs, better pay for workers If you voted One Nation: thank you. You’ve given us a stronger voice, and we won’t waste it. If you’re still on the fence: watch what we do next. Australia is worth fighting for. And we’re just getting started.

Watch how this little one is able to find success with just the tiniest assist from Dad. In developmental psychology, the “Zone of Proximal Development” is that area just beyond a child/learner’s independent ability - but a space in which he/she can find success with support (or “scaffolding”) from a more competent teacher or peer. Listen carefully here as dad breaks down the steps involved in descending the stairs. It’s a big task for such a little learner, but with his support and coaching she pulls it off. Notice that, other than in the opening seconds as he helps her clear a baby gate, Dad’s support isn’t physical. It’s all verbal guidance as he supplements her thinking with a little of his own. The social nature learning on display. 🎥 Lelah_and_Lou IG

Today, I had to respond to noise pollution coming from Impala Grounds (FLOODIES EVENT)after receiving multiple complaints from neighbors. The noise started in the morning and continued until 10 p.m., prompting us to take action in response to their concerns. Over five neighbors reached out, and we acted swiftly to restore peace in the area. I want to extend my gratitude to my fellow youths who continue to support the work we’re doing as a government. Together, we’re making strides toward restoring order and improving the quality of life in our city. Let’s keep pushing forward for a cleaner, quieter, and more livable Nairobi. ONE AMONG THE MANY MESSAGES RECEIVED FROM NEIGHBOR BELOW Orchid/Harlequins is a nuisance since morning. Tooooo noisy. Our windows are literally vibrating. This is insane and crazy 😧. They need to stop

Discrete Fourier Transform by hand ✍️ ~ 12 steps walkthrough below Here is a little-known secret about the DFT and the inverse DFT: it is just matrix multiplication in both directions, one the transpose of the other, exactly like the forward pass and backpropagation I drew in other examples. Goal: recover which cosine waves a signal is made of, using nothing but multiplication and addition. = 1. Given = Three signals written as sums of cosines, and a fourth, X, that we do not know yet. = 2. Frequency matrix F = Let us write the coefficients as a matrix. Each signal is a row, each frequency a column, so A = cos(w) + 2cos(2w) becomes [1, 2, 0, 0]. = 3. Sample the waves = We read the four cosine waves at ten discrete time points. That word "discrete" is the whole difference between this and the continuous transform. = 4. Cosine matrix W = Let us write those samples as a matrix: each frequency a row, each time point a column. = 5. Frequency to time = We multiply F by W. That combines the four cosine waves in the proportions F specifies, and the result T is the three signals as they would look in time. = 6. Transpose = Let us stand each signal up as a column. = 7. Time to frequency = We multiply W by that transpose. Every cell is the dot product of one signal with one cosine wave, which measures how much of that wave the signal contains. Zero means none of it. = 8. Scale = Let us multiply by 2/n, with n = 10. The projections come out five times too large, and this is the correction. = 9. Transpose back = We turn it back around, and it is F again, exactly. That is the check: the transform recovered the coefficients we started from. = 10. Now solve for X = Let us run the same multiplication on the one signal whose recipe we never knew. = 11. Scale = We divide by 5 again. = 12. Transpose back = And X reads [0, 0, 3, 2], which says X = 3cos(3w) + 2cos(4w). Note: I originally drew this to show that the DFT is a special case of a convolution layer, its filters fixed to sine and cosine waves rather than learned. No wonder, then, that a convolution layer free to learn its own filters can be trained to process signals. 💾 Save this post!

Cosine matrix W = Let us write those samples as a matrix: each frequency a row, each time point a column. = 5. Frequency to time = We multiply F by W. That combines the four cosine waves in the proportions F specifies, and the result T is the three signals as they would look in time. = 6. Transpose = Let us stand each signal up as a column. = 7. Time to frequency = We multiply W by that transpose. Every cell is the dot product of one signal with one cosine wave, which measures how much of that wave the signal contains. Zero means none of it. = 8. Scale = Let us multiply by 2/n, with n = 10. The projections come out five times too large, and this is the correction. = 9. Transpose back = We turn it back around, and it is F again, exactly. That is the check: the transform recovered the coefficients we started from. = 10. Now solve for X = Let us run the same multiplication on the one signal whose recipe we never knew. = 11. Scale = We divide by 5 again. = 12. Transpose back = And X reads [0, 0, 3, 2], which says X = 3cos(3w) + 2cos(4w). Note: I originally drew this to show that the DFT is a special case of a convolution layer, its filters fixed to sine and cosine waves rather than learned. No wonder, then, that a convolution layer free to learn its own filters can be trained to process signals. 💾 Save this post!

Discrete Fourier Transform by hand ✍️ ~ 12 steps walkthrough below Here is a little-known secret about the DFT and the inverse DFT: it is just matrix multiplication in both directions, one the transpose of the other, exactly like the forward pass and backpropagation I drew in other examples. Goal: recover which cosine waves a signal is made of, using nothing but multiplication and addition. = 1. Given = Three signals written as sums of cosines, and a fourth, X, that we do not know yet. = 2. Frequency matrix F = Let us write the coefficients as a matrix. Each signal is a row, each frequency a column, so A = cos(w) + 2cos(2w) becomes [1, 2, 0, 0]. = 3. Sample the waves = We read the four cosine waves at ten discrete time points.

Gilbert Strang taught linear algebra at MIT for fifty years. His last lecture is on YouTube. It has fewer views than his worst lecture. Nobody told students it was the last one. He just walked in, said "the final class in linear algebra at MIT," and started reviewing old exams. Google built a $2,000,000,000,000 company on one concept from this course. He is 88 years old. He still answers emails. This is MIT 18.06. Linear Algebra. The most watched mathematics course in history. Then the Markov matrix. Strang writes a transition matrix on the board. Three states. People moving between them every step. After enough steps - the system locks into a steady state that never changes. That steady state is an eigenvector. Google's PageRank works the same way. Websites are states. Clicks are transitions. The importance of every page on the internet is one eigenvector of one enormous matrix. Then least squares. Three data points. No line passes through all three. So you find the line that minimizes total error. That is how every AI model on earth is trained - including the ones running inside Goldman Sachs trading desks. Then the projection. The closest point on a plane to a vector outside it. Strang draws it in 30 seconds. That same operation is how Netflix decides what to recommend to 280,000,000 subscribers. Watch the moment he gives back the final exam answer and asks students to work backwards to the question - the room solves it in silence faster than any other lecture all semester. A software engineer told me 18.06 was the course that got her from $90,000 to $200,000 in two years. Same company. Different title. Bookmark this and watch later - after this lecture every dataset you touch will feel like a geometry problem waiting to be solved. MIT 18.06 Lecture 34 | Linear Algebra Final Review | Gilbert Strang

A 91-year-old professor is why Nvidia is worth $4 trillion. His name is Gilbert Strang. He teaches linear algebra at MIT. Every AI model on Earth runs on his course. The course has been free on YouTube since 2005. The videos have earned him nothing. MIT 18.06 opens with "The Geometry of Linear Equations." No advanced math. Strang takes a system of two equations, draws it two ways, and shows the class that a matrix is a picture, not an abstraction. The row picture is two lines that cross. The column picture is two arrows that sum to a target. Every neural network on Earth operates on the column picture. Strang first taught linear algebra at MIT in 1962. He wrote the textbook in 1976. It is on every serious engineer's shelf. Every quant fund, every ML lab, every rendering engine at Pixar is running his math. His central insight is that most people are taught matrices as bookkeeping. That is the first thing to unlearn. A matrix is a linear transformation. A linear transformation is a way of moving space. Once you see the space move, the math stops being algebra and becomes geometry. The Kalman filter is a linear system. PCA is a linear system. Every gradient step in a neural net is a matrix-vector product. GPT is a stack of matrix-vector products, each one a scene from MIT 18.06 running on a Blackwell GPU. He retired in 2023 after 61 years at MIT. The course is still up. Watched tens of millions of times. The chip is $40,000. Strang never asked for a royalty.
