#122 JJ. Good session. Very physical in a good way. Couple of weeks until grading. Tweaked moves for blue belt. Also did throw for throw, ne waza and 2v1 ground fighting which was a lot of fun. 🥋

[David Ghosh @MrInclusive]

First ever Ju-Jitsu lesson today.
Loved it 🥋

[David Ghosh @MrInclusive]

#121 JJ. Good session. Much less intense than last session and went through syllabus to refine understanding in technicals such as chokes and te gurama with black belts 🥋

Water usage has been a hot topic in the AI data center world, but the numbers may surprise you.

According to the Manhattan Institute, data centers use 0.2 percent of daily water usage in the U.S. and that number has dramatically decreased in the past few years due to a new method: liquid cooling.

By moving to 45°C liquid cooling, AI factories in favorable climates can use dry coolers instead of conventional cooling-tower-based systems, cutting facility cooling water use from roughly 2.6M gallons per MW per year to near zero.

Liquid cooling enables AI factories to be both water and energy efficient, while creating opportunities for heat reuse and dispersal to local communities, allowing these factories to become energy grid assets.

🇬🇧 UK hypersonic space plane could shrink London Sydney flight to just 3 hours

Britain is preparing to test the Invictus hypersonic aircraft, a next generation spaceplane concept aiming to travel at Mach 5 (over 3,800 mph).

Backed by the and developed with the , the project could redefine long haul aviation.

If successful, ultra long routes like London to Sydney could drop from 20+ hours to just 3 hours.

From airports to near space travel, aviation may be entering a new era of extreme speed.

BILLIONAIRE PAUL TUDOR JONES ON BUYING THE S&P 500 RIGHT NOW:

“IF YOU BUY THE S&P AT THIS CURRENT VALUATION, THE 10-YEAR FORWARD RETURNS ARE NEGATIVE WHEN YOU BUY WITH THE S&P P/E OF 22. THAT'S WHAT HISTORY SHOWS.”

JONES CALLED THE 1987 CRASH BEFORE IT HAPPENED.

HE'S NOT PREDICTING A CRASH.

HE SAYS THE CURRENT SETUP IS MORE LEVERAGED THAN ANYTHING HE'S SEEN, INCLUDING 2008.

“THE STOCK MARKET'S REALLY HIGH, AND IT'S GOING TO BE REALLY HARD TO MAKE MONEY FROM HERE.”

The UK has already minted 18 unicorns already in 2026

The total for 2025 was 20 so we are going to surpass it soon.

UK tech is on track to have its strongest year since 2021, and its not just AI companies that are performing well.

Consumer companies, fintechs, hardware, defence... the UK is firing on all cylinders.

Here are some of the UK's newest unicorns:

> OLIX from @jamesdacombe
> Huel led by James McMaster and now acquired
> Fresha from William Zeqiri and Nick Miller
> CuspAI from @ac_edwards_1 and Max Welling
> Granola from Christopher Pedregal and @samstphenson
> Nyobolt from Sai Shivareddy and Clare Grey
> @join_ef from @matthewclifford and @Alicebentinck
> Allica Bank from Richard Davies
> UFORCE from Oleg Rogynskyy

This is so cool. A full-body ultrasound using no radiation and no magnets.

Thanks to AI, Midjourney has found a way to scan patients in just 60 seconds, using only sound and water.

We are at the foothills of an age of medical miracles.

Hard hitting resignation speech by John Healey in the Commons, with a parting shot at the Chancellor

‘Our adversaries don’t follow timetables set by the Treasury,’ he told MPs

‘This is the age of hard power and rising threat, this is not the moment for calibration or incremental change. That means bigger politics, bolder priorities, harder choices,’ he said

He repeated his call for Britain to commit to spending 3% of GDP on defence by 2030

A UK startup can now assess skin cancer from a smartphone!

People have been talking about using AI to cure cancer.

This is the first time I've seen a company actually come close.

Users take a close-up photo of a mole or lesion through the app and it returns one of two results: clear, or a referral for further assessment.

The same decision a dermatologist would make but made autonomously by an AI on a consumer device.

The technology has already been used on 230,000 patients and identified over 20,000 cancers, but this is the first time it's being used on a smartphone.

CRAZY, amazing stuff from the team at @SkinAnalytics

Your phone charger can electrocute a toddler who pokes a fork into the socket. The British plug cannot. That difference comes from a 1947 engineering project that refused every shortcut and turned a household plug into one of the most deliberately safe objects ever mass-produced.

Britain published BS 1363 in 1947, built for the post-war housing boom. The country was wiring millions of new homes at once and needed one standard that would work safely for everyone. They picked the most paranoid option available.

The earth pin (the large top prong) is longer than the other two. When you push a British plug in, the earth pin goes in first. Inside the socket, it presses a lever that opens two metal shutters covering the live and neutral slots. A fork pushed into an empty British socket hits only shutters. The shutters block it.

The two conducting pins are also coated in plastic for their lower half. A plug halfway out of the wall is still safe to touch. You would have to pull it completely clear before any live metal is exposed.

Inside every plug is its own fuse. UK homes wire their sockets in a loop called a ring circuit, which runs at 32 amps, enough to melt a lamp's cord if the cord fails. So each plug carries a fuse matched to the appliance: 3 amps for a lamp, 13 for a kettle. When something goes wrong in your appliance's wiring, only that plug's fuse blows.

The standard US plug (flat two-pin or three-pin) has none of the pin coating and no individual fuse. American building codes began requiring shuttered outlets in new construction in 2008, decades after Britain made shutters standard. Even those newer shuttered versions lack pin coating and plug-level fuses.

Britain's plug is bulky because a fuse, a shutter mechanism, insulated pins, and three contact prongs all need room. The plug looks the way it does because safety engineers refused to sacrifice any of those features to make it smaller, and that decision is now 79 years old.
