Fully agreed. You can never prevent all issues because there's always a chance for a fire, bitrot due to cosmic rays etc and thus you can only reduce the probability as you correctly concluded. Unfortunately the world we are in right n

Most CPU architectures provide atomic read, write and barrier primitives. Locking is a higher level interface and usually involves use of those atomic primitives. The point is that once you have these low level guarantees, you can actually

When you say transactional storage do you mean hardware support for transactions? I don't think that would be required. As long as the storage hardware interface (e.g. NVME) guarantees certain low level primitives like atomic sector wr

I'd argue some modern hardware e.g. NVME SSDs already expose a hardware interface that would let a new transactional storage API be faster than what we have right now. Unfortunately it is a rare example in a see full of specs that do t

My point is that we need a new storage interface that is transactional. It's extremely hard to build a sound interface on the existing ones. And it would not be built on the existing FS because those are already built for the broken in

One example for marking dirty pages as clean after fsync failure that they mention filesystem developers having given them is a USB stick that has been pulled and keeping dirty pages causing memory leaks in that case. But to me that argumen

The paper explains that even crashing after fsync fails you can end up with lost or corrupted data because after the next start you might get the wrong data from the page cache which survives the crash as it's not part of the programs

I wonder why they limit it to 2 WAL files instead of creating a new WAL file once the latest one reaches a certain size and a checkpoint is done. Then delete the WAL files that have been successfully flushed to the main DB. That could minim

In Bitcoin transactions are not just "from", "to" and "amount" even if some wallets abstract them in that way. In the simplest case there are coins that get marked as being spendable by some public key (address

Coins in Bitcoin are not necessarily fungible. Tainted coins (from sanctioned individuals, from hacks etc) are traced and for anyone else who has to adhere to for example US law these tainted coins are not of the same value as non-tainted o

Yes but in Bitcoin like mentioned you can ignore those coins and never use them. In Ethereum one could argue you are using them whenever you are doing your next transaction because there is no concept of coins that can be differentiated. It

You are misunderstanding his point even though masklinn explained it. It's not about the specific point of operator precedence. It is about designing something that has internally sound logic but is very unexpected by a typical new use

That is the weight of the hydrogen fuel. It does not include the weight of the tank nor the fuel cell so is not comparable to battery weight in a regular EV. The trucks also have 72kWh worth of batteries in them and it is not clear if a 400

While you are correct that the neutron star has angular momentum and then you'd use the E^2 = (p c)^2 + m0^2 c^4 for it, the question was if it is losing mass by emitting neutrons and how much. For that, the momentum energy of the Neut
