It's great scientific progress, but seems doomed to costing more than actual reuse.

This was our approach too, it worked pretty well. When Covid and the lockdowns hit it all went out the window for us. It was simply to hard to supervise the kids and work as well. I'm glad that you have made it work for you.

I agree with you that I want a non-magic approach. I want to understand the nitty gritty so I am building my code with solid foundations based on how the actual hardware works. However, this is not an approach that works for the masses. The

While mass to orbit costs as much as it does now, sure. However later on it's gonna be great to have humans closer to the working robots to reduce the round-trip latency. They could also perform tasks robots are not suited for. Conside

I think it's a really responsible decision by SpaceX to not put their StarShip stage into a full orbit until they have demonstrated the ability to get it back out of orbit. They should be applauded for this, along with their iterative

Plus, your payload needs to be gun compatible. Not gonna put people in there.

> 5 and 20 Starship launches per mission That is not actually such a big deal when you realize they are just ferrying fuel on a reusable rocket. They're also doing it well in advance of the mission. There is a massive logistics chai

Each streamer adds a delay to their stream. This means that any stream forwarded to you by another streamer is going to be delayed. The delay was between SpaceX recording and uploading an event and Everyday astronaut decoding it at their mi

At least in LEO you need to keep expending DeltaV to keep stuff in orbit. Trace atmosphere slows everything down and would eventually clean LEO at 500km of relevant junk in about 25 years depending on altitude. https://space.stac

Also, as mass to orbit gets cheaper you can build your payload more cheaply. Many compromises in complexity and material cost are made to minimize payload mass - we'll be able to launch cheap and heavy satellites and probes into orbit

The shuttle boosters required rebuilding / refueling (which is solid rocket goop) and the fuel tank was completely lost and required rebuilding. The head shield tiles were extremely fragile on the shuttle. It was never a fully reusable

Especially when each rocket successfully makes it further into the test, beyond the point where the previous iteration failed.

I think there is a disconnect here between the decision makers and the experts in the Police Garage.

The post is fundamentally about all the performance of making stories, assigning points, allocating work and doing standups all the time. None of that is required to actually create software. If people are judgemental around what stories ar

To do this with any DC battery you add a solar battery charger to accept the panels and an inverter to turn the DC into mains 230V you can use.

nmi - Nautical mile (1 nmi/hour mentioned above) Today the international nautical mile is defined as 1,852 metres (about 6,076 ft; 1.151 mi). https://en.wikipedia.org/wiki/Nautical_mile

Most technology has a limit like this (for instance CPU transistor size in the past). However once this is a proven technology, money will be invested in solving these issues.

Agent - Something that makes decisions and actions that are not pre-programmed or predictable. Humans are definitely agents. LLM (eg Chat-GPT) are not quite there yet (they don't take action on their own). Tool - Pretty much everything

One is a failure to act as an agent - to control the car and make decisions. Another is a failure to even be a reliable tool - to do what the operator commands. Very different. Creating Agents is a lot harder.

Therac-25 is more like a stuck accelerator pedal. The operator did not command the machine to deliver too much radiation, that happened outside their control.

Unfortunately it is very difficult to remain vigilant when the automated system seems to be doing a great job. Eventually you will become distracted. Even in accident cases, remember that the Teslas involved are not new - they have had doze

I'm sure even in this case, risking the air-frame of the bomber or friendlies on the ground below is not ideal. Bear in mind cruise missiles are usually launched from friendly territory. Also, failures might reduce the accuracy of the

Fascinating! What would you consider the water source for a BLEVE? There is no drilling liquid, so are you concerned about drilling near a water source and the well becomes suddenly contaminated with water, then steam?

More standoff means that the armor can spread a blow over a larger deflection without injuring the wearer. Also, a blow is going to contact a larger area of metal during the deflection. So you could use lighter or more flexible material - h
