허리 때문에 밤마다 뒤척이던 나… 일본 척추 전문의가 알려준 방법 하나로 끝남.
침대에 베개 하나 놓고 5분만 누워있으면 됨.
그게 다임.
특정 자세 잡고 숨을 길게 내쉬는 것뿐인데 이게 척추신경 눌린 거 풀어주는 원리라고 함.
운동도 아니고 그냥 숨쉬기라 부담도 1도 없음.
밤마다 허리 통증으로 잠 설치는 사람이면 오늘부터 자기 전 루틴으로 하나 만들어보길.
Neil Movva (@neilmovva) started his career at Nvidia, working on GPUs and kernels, and has an unusually deep understanding of inference, from software to chips to power.
We spend a lot of time on each of those layers, how they connect, and where the important tradeoffs are.
What makes this conversation special is how detailed it is (like a 401-level class), yet Neil makes it remarkably clear and easy to follow.
Today he runs Sail Research, a company building infrastructure for agents to make tokens as cheap as possible.
We discuss:
- Latency versus throughput
- Why there are no bad chips, only bad pricing
- The end of kernel engineering
- Buying chips and power no one else wants
- New chip architectures
- Nvidia lore + his contrarian view of the company
- Open source and the frontier labs
I learned a ton. Enjoy!

@ImperiumHindu But must applaud the propoganda this upwordiyas run along with dharmic champion sai leepak ji..once I was under impression that kadhi is really destroyed by mudi...once you visit kashi on yiur own then only know how grt is corridor..
Reading this excellent report on EV component manufacturing localisation in India by @ieefa_institute. The report suggests that powertrain, power electronics, and charging equipment could reach 90–100% localisation by 2030. But rare-earth supply, permanent magnets and semiconductor bottlenecks persist, and will continue to limit domestic value addition unless local manufacturing is established.
The report is very well researched and has brilliant figures and tables for EV manufacturing aficionados.

In Aug 1951, a sleek, twin-seat aircraft roared over the runways of Bangalore, executing flawless aerobatic loops in front of a stunned crowd of defense officials. It was the HT-2: the very 1st aircraft entirely designed, engineered & manufactured from scratch on Indian soil. When global aviation experts rushed to see the state of the art lab where it was conceptualized, they found no high-tech computing/imported foreign testing rigs. The plane had been calculated using basic slide rules & hand-drawn drafting boards by an Indian engineer who had once studied under the absolute pioneers of rocket science in Germany.
He gave India its wings, yet while modern space & rocket programs are celebrated across the country, the pioneer who laid the literal bedrock of Indian aeronautical engineering has become a ghost hidden in the jet wash of the machines he birthed.
Born in 1908 in a small village near Kolhapur, Maharashtra, Vishnu Madhav Ghatage was possessed by fluid dynamics. While ordinary students were content with textbook physics, Ghatage wanted to know how invisible air currents could lift tons of metal into the sky. His intellect was so undeniable that he traveled to Germany in the 1930s, entering the University of Göttingen, the undisputed world capital of fluid mechanics.
There, he completed his doctorate under none other than Ludwig Prandtl, the undisputed Father of Modern Aerodynamics. Ghatage sat in rooms with the absolute elite of global rocket & jet propulsion engineering. He was offered lucrative paths to stay in Europe/move to America to design the next gen of Western aircraft. He refused it all.
He packed up his complex aerodynamic eqns & flew back to a colonized India that did not even have a single factory capable of manufacturing a standard aircraft aluminum panel. When Ghatage joined HAL in Bangalore, he faced a wall of absolute skepticism. The prevailing colonial mindset was toxic: Indians are built to fly planes, not to design them.
The British establishment firmly believed that India would always be a customer, forever buying obsolete aircraft from European factories. Ghatage decided to shatter that narrative permanently. In 1948, he took a blank sheet of paper & began sketching the Hindustan Trainer-2 (HT-2). India desperately needed a primary trainer aircraft to teach its young pilots how to fly w/o relying on expensive, imported British Tiger Moths.
Working day & night in uncooled sheds, Ghatage & his small team of Indian technicians calculated every single rivet, wing spar & fuselage curve by hand. They had no automated simulation software; every stress test was done manually.
When the HT-2 took its maiden flight on 13th Aug, 1951, it was incredibly stable, highly responsive & boasted an innovative all-metal structure that made it vastly superior to contemporary Western trainers. For the next 2 decades, every single pilot who entered the Indian Air Force & the Indian Navy learned the art of flying by gripping the controls of a machine designed by Dr. Ghatage.
Ghatage was not a 1 hit wonder. He looked at India's vast agricultural fields & realized that the country needed a rugged, ultra-cheap flying jeep that could land on mud tracks, help farmers spray crops & connect remote villages. He went back to the drawing board & designed the HAL Pushpak: a light, high-wing cabin monoplane that became the darling of flying clubs across India.
He followed it up by designing the HAL Kiran, a jet trainer that would go on to power the iconic Surya Kiran aerobatic display team for decades. Ghatage was an absolute polymath of the skies. He designed gliders, pioneered the study of IC engines under tropical conditions & laid down the precise curriculum for the Aeronautical Engineering Department at the IISc.
During the late 1950s & 60s, the Indian govt became obsessed with supersonic speeds. Desperate to build a Mach 2 fighter jet, they bypassed Ghatage’s steady, incremental domestic pipeline & hired a German designer, Kurt Tank, to lead the HF-24 Marut project.
The glitz of the foreign superstar engineer & the massive geopolitical theater of jet-age politics completely pushed Dr. Ghatage out of the limelight. His quiet, systematic work of building an independent, native aviation ecosystem was sidelined in favor of high-profile, fast-tracked projects that ultimately stalled when foreign engine contracts fell through.
Ghatage retired quietly in 1970. He did not lobby the press, did not write scathing memoirs about the bureaucracy that choked his later designs & spent his final decades in Bangalore focusing on fluid dynamics research & music. He passed away quietly into the night on 6th Dec, 1991.
Every single time an Indian fighter pilot streaks across the sky/a commercial airliner lands safely on our tarmac, they are operating within an airspace mapped out by the calculations of a single man. Dr. Vishnu Madhav Ghatage taught a newly born nation how to break its gravity & touch the clouds, but we left the literal Father of Indian Aviation to remain a ghost standing silent on the very runways his genius built.
We live in an age of miracles.

A drone flying with no battery tether sounds impossible until you see it. GuRu wirelessly transmitted power through the air to directly run an untethered drone from 30 feet away and has kept one flying for 96 hours straight. Power beaming is moving out of science fiction fast.
