By your logic, obligate carnivores would have the larger brains. Humans are obligate omnivores. Studies show no significant differences in cognitive function, cardiovascular risk, or bone health when vegan diets meet recommended dietary allowance levels. Animal protein contributed during the evolution of the human brain, but the development was driven by cooking. Cooking externalized the energy required for digesting food, which allowed for a reduction of jaws/jaw muscles, and especially gut size, freeing energy that could be used by the brain instead.

Also, the brain is fueled by glucose, not protein …

One has to find the right balance between security and comfort, and this entirely depends on the threat model one has. Nowadays, I will always enable full-disk encryption on all of my devices, even if I then decide to store the keys in TPM and unlock the disk at boot.

I have at least 5 half-broken HDDs sitting around, completely unencrypted, I have no idea if they still work, but they are surely full of private data that I would like to have purged. I fear mechanical destruction might be the only solution for some of them, but just wiping them manually is more effort than doing nothing, so I guess they will still be around for some time. And with SSDs, there is no reliableway delete all data.

With encryption? Just delete the key and you are done.

The threat model changes in the future? Easy, the data is already encrypted.

Hmm. Let’s say I add 6 SSDs, 2TB each, for a total of 600€. In a RAID6 configuration, that gives me 8TB of storage. Compare that to a classical NAS with 2×8 TB HDDs for a total of 350€.

The HDDs will draw around 4W idle each, 8W in total. Assuming 0.3€/kWh, over a span of 5 years, that is approximately 100€. The power consumption of the SSDs will be negligible.

So, just in terms of storage, the SSD solution is around 33% more expensive over 5 years. If you include the cost of the NAS itself, the price increment is even less noticeable.

Here you can get 12TB, new, from a trusted German seller, for 129€, which is 1.075 cents per GB.

Amazing! What is left to do now? Orbital Raptor relight and dummy payload deployment? Do they need a new launch license for that, or is the current one (which should be good for similar flights if I understand correctly) sufficient? S31 + B13?

I assume they will want to demonstrate the V2 flap design before attempting a ship catch. They also need the second tower for that, unless the booster can be destacked sufficiently fast.

TOR exit node IP addresses are well-known. If YouTube wants to, they can just block the TOR network.

You can check heavens above (adjust your location) to check when it will be visible for you.

Wait a second, it’s going to pass over my house in 5 minutes!

Edit: Shit, clouds!

Edit2: I was able to see it through a few gaps in the cloud cover!

Without UEFI, the boot process is different for each device, requires a custom boot loader, or at least explicit support by the operating system. Is your laptop going to be supported by the distribution you want to use? What about in 5 or 10 years? With UEFI, the boot process is standardized, so it should just work.

That was some Columbia-level damage that Starship experienced during reentry, and yet it successfully retained control authority, completed a soft landing, and everything was live streamed. Amazing!

The booster seems to be almost ready for the first catch attempt (depending on the accuracy of the landing).

I wonder to what extent they can retrofit Ship 30 to reinforce the hinge of the flaps, and how long that is going to take? On the other hand, the ship did survive, so maybe they will just repeat the launch without any major fixes, and try a few different things? (Deorbit burn, maybe even suborbital test-mass deployment, or more aggressive tests of the heat shield?)

The next-generation Starship design has less exposed flaps with reinforced hinges already. But is it already in production?

Then the editor, all extensions, language servers, etc. are all running as root.
