Ocean Heat Source 09: The dominant source is either a) geothermal/hydrothermal heating from below, or b) electromagnetic induction. Here’s where I’m at with the five mechanisms I’m testing to explain the abyssal warming acceleration: 1. adiabatic compression: closed 2. isopycnal heave: quantified; observationally limited 3. AABW/overturning: closed as the...

In the last ten years, I've seen: 1. A small cottage industry of made-to-measure Shetland sweater knitters disappear. 2. Two bridle leather goods makers close down. No replacements. 3. A major West End bespoke shoemaking firm shutter. 4. Two major American suit factories narrowly saved from the brink of bankruptcy (almost completely wiping out suit production in the US). 5. A major American shirtmaking factory also narrowly saved from permanent closure. 6. Vanners, one of the oldest silk mills in England, having started in 1740, was repossessed by administrators for the second time in two years. Management told me it's largely because of the decline in high-end neckwear sales around the world. 7. One of Britain's best leather goods manufacturers, RBJ Simpson—otherwise known as Simpson London—closed. 8. Caerlee Mills, which made some of the best Scottish cashmere knitwear in the world, many under the name Ballantyne, turn off its machines after 225 years of operation. The video below shows the factory being demolished. 9. Several bespoke tailors and bagmakers pass away or retire. In many cases, they did not have apprentices, so there was no one who was able to take their place. Their businesses just closed. 10. One of the best American tailors (a cutter, technically) called me in 2021 after he lost one of his coatmakers to COVID. He wanted to know if I had any recommendations to coatmakers in the US or around the world, as he doesn't know anyone left in the US who can sew a bespoke suit jacket or sport coat together anymore. The only people I could recommend to him were in Southern Italy.

.Josh Wolfe: Anybody Using DeepSeek App Is 'Absolute Fool' "Anybody using the DeepSeek app is an absolute fool. If you're using DeepSeek on companies like Together Compute, one of Lux's companies, which can get rid of the CCP censorship, then it's probably okay. But remember, the open-source movement is something we deeply believe in. Most great technologists, entrepreneurs, and venture capitalists are on the side of open source. The closed-source models that have consumed tens of billions of dollars are the ones that are really going to be at risk. When you look at Hugging Face, a major repository, or Together Compute, Runway ML, and a lot of Lux's companies, they have been pioneers in open source. Now, why am I not worried about open source, even with the DeepSeek model? As long as you don't have the CCP censorship on it, the models with their open weights allow people to run on their proprietary data. This means companies like pharma or defense companies that have their own siloed, proprietary data—think about Bloomberg with their proprietary longitudinal data, or Meta with their data—are the ones who will have the edge. Even as open source takes hold, these companies will still dominate. I’m not worried about open source being the problem. I’m more concerned about people overfunding closed models with no proprietary source. A lot of capital is going to be burned there, and we’re already seeing that with people worried about OpenAI in some aspects."

The video shows the trials of the VT-1-1, a turretless tank with 2 x 105 mm guns, firing on the move at the Putlos training ground in 1976. The casemate (turretless) tank, designed for combat while moving, was introduced in Germany in the mid-1970s as a twin-gun casemate tank (the Soviet term for a "turretless tank"). For practical firing tests in the "target pass" mode, two prototypes were built in the mid-1970s. The first prototype, VT 1-1, was armed with two 105 mm guns, while the second, VT 1-2, was equipped with two 120 mm smoothbore guns. Additionally, the VT 1-2 featured a functioning autoloader behind one of the guns, with a firing rate of 10 rounds per minute. The vehicles were developed as part of the KPz 3 or Leopard 3 project. In both prototypes, the main guns were semi-fixed (with aiming and stabilization only in elevation). The chassis solutions were derived from the KPz 70 (MBT 70) program, with the running gear shortened by one road wheel (five road wheels per side). The vehicles weighed 36.8 and 43.5 tons, respectively, with a chassis rotation speed of 60 degrees per second. To achieve high maneuverability on rough terrain, 12-cylinder diesel engines from the MB 873 series with enhanced power were used, equipped with four turbochargers: 2000 hp for VT 1-1 and 2200 hp for VT 1-2. This provided an impressive power-to-weight ratio of 54 and 50 hp/ton, respectively, with acceleration to 55 km/h in 11 seconds, though only in a temporary "turbo" mode, as the standard power was 1600 hp. The accuracy of firing with two guns was unmatched by single-gun tanks, as confirmed by the tests. However, due to the novel combat approach, this revolutionary tank concept was rejected by the customer after trials in favor of the conventionally designed Leopard 2. In essence, although the project was developed as the Leopard 3, a tank for the future, it was, in reality, a parallel project and a potential competitor to the Leopard 2. Achieving the firepower, protection, and mobility of the Leopard 3 within reasonable weight limits was impossible with a conventional layout. At the same time, a significant tactical drawback of the casemate concept (including twin-gun casemate vehicles) is the linkage between the direction of fire and the direction of movement, which in many cases could complicate unit and formation control (according to German experts in the 1970s). Moreover, the VT 1-1 and VT 1-2 can hardly be considered balanced vehicles—they could have been simpler. The vehicles' mobility was exaggerated, with the main engine, transmission, auxiliary engine, batteries, and other systems occupying two-thirds of the vehicle's length. Pros and Cons of VT 1-1 and VT 1-2: Considering the key challenges, the twin-gun casemate concept can be evaluated as follows: Pros: Compact design due to a small internal volume. Two guns provide high firepower and hit probability. Cons: The weight advantage of the casemate design is largely offset by the integration of a second gun. Fire control alone results in high complexity, leading to increased maintenance costs and overall expenses. In 1975/76, five Gefechtsfeldversuchträger (GVT, combat test platforms) were developed and built for further mobility and concept trials. These were smaller than the VT 1-1 and VT 1-2, weighing 30 tons. The GVT 01-05 were equipped only with mock-up guns and laser firing simulators (TALLISSI) and telemetry systems, built using chassis components from the Leopard 1. The GVTs were used at the IABG facility in Lichtenau and the tank training school in Munster to test the twin-gun turretless tank concept in realistic exercise conditions, which is why five vehicles were built. However, the Leopard 2 was already in production, and tank crews showed little enthusiasm for this unconventional vehicle requiring a new approach.
