It is intensely funny to me that tech bro CEOs on an annual salary of 15 petabillion dollars think data centres can go in space because it's very cold but actually they would get obscenely hot because heat won't radiate into the vacuum of space

taranis.ie/datacenters-...
cold coolant returned to the loop. Typically the coolant is cooled via convective cooling to the air, so one way or another this is how things work on Earth. In space, there is no air. The environment is close enough to a hard, total vacuum as makes no practical difference, so convection just doesn't happen. On the space engineering side, we typically think about thermal management, not just cooling. Thing is, space doesn't really have a temperature as-such. Only materials have a temperature. It may come as a surprise, but in the Earth-Moon system the average temperature of pretty much anything is basically the same as the average temperature of Earth, because this is why Earth has that particular temperature. If a satellite is rotating, a bit like a chicken on a rotisserie, it will tend toward having a consistent temperature that's roughly similar to that of the Earth surface. If it isn't rotating, the side pointing away from the sun will tend to get progressively colder, with a limit due to the cosmic microwave background, around 4 Kelvin, just a little bit above absolute zero. On the sunward side, things can get a bit cooked, hitting hundreds of centigrade. Thermal management therefore requires very careful design, making sure that heat is carefully directed where it needs to go. Because there is no convection in a vacuum, this can only be achieved by conduction, or via some kind of heat pump. I've designed space hardware that has flown in space. In one particular case, I designed a camera system that needed to be very small and lightweight, whilst still providing science-grade imaging capabilities. Thermal management was front and centre in the design process – it had to be, because power is scarce in small spacecraft, and thermal management has to be achieved whilst keeping mass to a minimum. So no heat pumps or fancy stuff for me – I went in the other direction, designing the system to draw a maximum of about 1 watt at peak, dropping to around 10% of that wh… Cooling even a single H200 will be an absolute nightmare. Clearly a heatsink and fan won't do anything at all, but there is a liquid cooled H200 variant. Let's say this was used. This heat would need to be transferred to a radiator panel – this isn't like the radiator in your car, no convection, remember? – which needs to radiate heat into space. Let's assume that we can point this away from the sun. The Active Thermal Control System (ATCS) on the ISS is an example of such a thermal control system. This is a very complex system, using an ammonia cooling loop and a large thermal radiator panel system. It has a dissipation limit of 16kW, so roughly 16 H200 GPUs, a bit over the equivalent to a quarter of a ground-based rack. The thermal radiator panel system measures 13.6m x 3.12 m, i.e., roughly 42.5 square metres. If we use 200kW as a baseline and assume all of that power will be fed to GPUs, we'd need a system 12.5 times bigger, i.e., roughly 531 square metres, or about 2.6 times the size of the relevant solar array. This is now going to be a very large satellite, dwarfing the ISS in area, all for the equivalent of three standard server racks on Earth.

This is a extremely poor idea: "According to revelations in Guardian Australia this week, there will be no safety net – no scope for either the NDIA delegate or the administrative appeals tribunal to amend the budget. In other words, the computer will have the final say."

Did we learn nothing from robodebt? NDIS automation will put vulnerable lives at the mercy of machines | Georgia Van Toorn
It’s hard to overstate the potential dangers of replacing discretion with algorithms in a system as consequential as the national disability insurance scheme Never again. That was the resounding message delivered via the robodebt royal commission from the thousands of Australians whose lives and livelihoods were upended by the cruellest experiment in bureaucratic automation the country has ever seen. Now, with plans under way to automate the calculation of individual NDIS support plans, it appears we’ve reached new heights of institutional amnesia. Once again, vital lifelines to support will be placed at the mercy of automated systems. Only this time, the mechanisms for review and redress will be vanishingly thin. Continue reading...

It is now clear when Albo said "no-one left behind", he really meant:
- the gambling industry
- big media
- fossil fuel lobby
- for-profit childcare corporations
- aged care companies
- employment service providers
- property developers...

But Australians with the greatest needs? Yeah nah. #auspol

Gambling ruins lives. It is absolutely unacceptable that the Albanese government will continue to choose vested interests over the wellbeing of Australians and hide behind a watered-down policy - if they ever introduce one. We need action on gambling harms now.
