A custom script that essentially reads /dev/urandom and feeds the hex seed to bip39tool from pybitcointools.

No because I feed my wallet public key (xpub) to scripts that derives the wallet addresses, and I verify that the derived addresses match what my wallet generates. I'm paranoid like this :) Granted that would be really inconvenient to

I would be immune to this attack because I always generate my own seeds, on a trusted computer. So I set up hardware wallets to import my seed, instead of trusting their seed generation algo. Of course this procedure doesn't protect

Passwords will never be supplanted? As always, it's a false dichotomy. Passwords will continue to be useful for some scenarios, but in others they will and are being replaced by other methods such as biometrics, U2F tokens, etc

The flip side of the coin is that 95%+ of Twitter's user base (every unverified user) is now going to have a worse publishing experience due to less engagement, less visibility of their tweets. Time will tell if prioritizing the consum

It's the AV that was calling TdhFormatProperty(), not FF. The problem was mostly on the AV side, not FF. FF itself was generating many events due to too many VirtualProtect() calls which in itself was only a smaller part of the problem

What makes you think this was used for only $5k? In these cases, hackers usually target many victims, not just one.

The victim (ctvo) claims in another comment down the thread that he had a unique Gmail password not re-used on any other service. I commented assuming this premise is true.

As an InfoSec professional, what you describe sounds more like a device-level compromise of your iphone, perhaps through a malicious app, or link you clicked. What your experienced can't be done with just a sim swap attack, as you woul

I have FSD too, and my opinion is that although it takes unsafe actions almost on a daily basis, most of these errors are minor, easily rectified by me the driver, and most of the time it drives just fine, in fact better than a human driver

Ah, that makes sense ! 11.37 µSv/hour is only about 28 times higher than background radiation.

by mrb 4y ago
Background radiation is less than 3.5 mSv/year, or less than 0.0004 mSv/hour. So if these tiles radiate 11.37 mSv/hour that would be 28 000 times more than background radiation !

Were they high-endurance SD cards? In my experience, people usually aren't aware there is a difference between standard and high-endurance SD cards. The former should last years on a light I/O raspberry pi workload.

It appears there was little to no attempt to optimize for a small code size. The code could be minified and simplified to a lot less than 19 kB. I was curious to look at the size of a decent MIDI version of Oxygène IV ( https://ww

The key takeaway, especially for the author who wants things to "just work", is that he should have used a USB external disk, instead of a Thunderbolt external disk. OSes tend to have more issues with Thunderbolt disks (such as th

You are right. I forgot to account for the fact combustion engines have a terrible thermal efficiency: about 20%, which gives the boat only 2 kWh per liter of diesel, meaning it was using 200 kWh daily, more in line with the electrical vers

Usually it's the fault of the Linux drivers. They don't correctly configure the various integrated peripherals to draw as little current as possible: the WiFi chip, the Bluetooth chipset, the webcam, or whatever random integrated

The boat used to consume 100 liters of diesel daily, which is equivalent to 1000 kWh in energy (10 kWh per liter). But after electrification they claim only 150-200 kWh usage per day. This doesn't add up. Were the diesel engines idling

Have you seen the massive size of that drum of electric cable on the boat? It weights definitely more than 1200 lb, which is the weight of a Tesla 100 kWh battery. So the boat would be actually more lightweight after replacing that drum wit

The price could remain constant after the second time A sells to B. Their wealth still has increased, hence demonstrating it's not a zero-sum game (let alone negative-sum). Some things that are actually zero-sum games are futures or op

Not at all. Here is a simple counter-example: A has some bitcoins, he sells a few to B. Later price increases, and A sells more bitcoins to B. In total, the same $ went in as the $ that went out, but both A's and B's wealth increa
