"this hard drive from 1986 won't spin up. We tried freezing it, tapping it with a rubber hammer, and opening the case to lower the friction... there's only one option left: GET OUT THE C4 EXPLOSIVES!"
"what if you crush the case?" (probably still resuable if you don't bend the platters, since you could swap the case+PCB in a cleanroom
if you have magnetic material which is in some range of 0-100% magnetized, it starts at 50%
You write at 0, it goes down to 10%
if you instead wrote a 1, it would go up to 90%
but the 1 will only be pushed down to like 20%, as it doesn't fully overcome the previous magnetization
like "if we had magnetoscopes that were 10x more sensitive and could cool down the drive to within a couple degrees of absolute zero, maybe?"
With some clever hacking of the firmware/hardware, you could possible have a hard drive which has been been programmed to avoid the tracks affected by the hole
but it's theoretically possible.
it might vibrate itself to death.
1. they don't want to be surprised by the secret technological abilities of enemies
They also thought the much more complicated & secure Lorenz machines were were not decipherable... they were wrong.
If you are like "We erase all our drives by writing them with zeros" and then one day are like "UPDATE: MAKE SURE YOU WRITE ZEROS THEN ONES THEN RANDOM CHARACTERS..."
By going overboard about your security methods, you keep them guessing about your capabilities.
It's a 56-bit cipher, and was an important advance in publicly-available cryptography.
But they published an early version in 1975, then later updated it after talking with the NSA.
They don't want to reveal this technique (because then the enemy will harden their systems against it) but at the same time, they don't want their domestic systems to be vulnerable to it
Let's say the NSA figures out how to hack into every linux machine...
The work the UK did to so completely hack the Engima machine was kept secret for decades
Like, if every time the Nazis sent out a submarine, a British destroyer sailed directly to it and sank it, they'd start to get suspicious about the security of their codes
But man, this spy is great. Let's give them a medal, and tell them to try to be a bit faster with the radio messages next time..."
They told him to go to the UK and recruit more local British agents to spy for the Germans
He reported having recruited Brits to help him spy, and send along reports of their discoveries, including blaming them for all any incorrect information that came through.
He'd just made the German Navy waste a ton of resources trying to find and sink an allied convoy... which didn't exit.
Like, when his "Liverpool agent" didn't tell the Germans about the big fleet movement leaving that port, he said that the agent had suddenly fallen ill, and a fake obituary was put in the newspapers
So he "hired" a radio operator, and the Nazis sent over information on the encryption system he would use.
This wasn't Enigma (it was a manual system), but was actually really helpful for further Enigma codebreaking
Which the allies could intercept
1. the encrypted Enigma transmission
2. the original plain-text version, because THEY WROTE IT
They specifically set it up to cause delays for accurate messages and to have inaccurate but-vaguely-close information.
"no. Patton is about to send 75 divisions to invade Pas de Calais! Our best agent is certain of this."
So he had both, making him one of the very few people to get decorated by both sides of WW2.
In reality he retires to Venezuela, running a bookstore under a new name.
I don't think that was even legal in 1940s Britain.
I need to go get some coffee and maybe turn down my ADHD from a 9 to maybe a 6 or 7.

Everyone likes to forget this episode just because it's terrible, but we were really sleeping on inherent comedy in a unfreezing an investor 300 years in the future and having them discover we've transitioned to a moneyless post-scarcity utopia.
it's like a classic twilight zone episode.
in fact, it IS a twilight zone episode.
The Rip Van Winkle Caper, Season 2, episode 24.
Four criminals steal a million dollars of gold bars, then put themselves in suspended animation for a hundred years to hide from the law.
they wake up, then start killing each other from mistrust, then the last one dies in the desert, as he offers a gold bar to the driver of a passing car, asking for water and a ride into town
the confused driver walks back to his car with the bar, and his wife asks what the gold bar is.
he says something like "It's gold... they used to use this for money, before we figured out a way to manufacture it."
He tosses it away, and drives off.

So I got out some CF cards and noticed something odd about this one. Do you see the weirdness?
How the fuck is a CF card "USB Enabled"?
So CF cards are a weird beast that act as either a PCMCIA card or an ATA/IDE card depending on a mode pin.
They're definitely not USB.
And it's not like that weird SanDisk card I have which you can fold in half and plug it in as a USB device.
It turns out the reason for "USB Enabled" is because it's a Lexar drive from the jumpSHOT era.
This is a normal CF card in most cases, you can use it in normal CF card readers and such

Flip it over, bend it in half, and now you can plug your SD card right into a USB port pic.twitter.com/jeBefP2xU1

MDZS is laden with buddhist references. As a South Asian person, and history buff, it is so interesting to see how Buddhism, which originated from India, migrated, flourished & changed in the context of China. Here's some research (🙏🏼 @starkjeon for CN insight + citations)
1. LWJ’s sword Bichen ‘is likely an abbreviation for the term 躲避红尘 (duǒ bì hóng chén), which can be translated as such: 躲避: shunning or hiding away from 红尘 (worldly affairs; which is a buddhist teaching.) (https://t.co/zF65W3roJe) (abbrev. TWX)
2. Sandu (三 毒), Jiang Cheng’s sword, refers to the three poisons (triviṣa) in Buddhism; desire (kāma-taṇhā), delusion (bhava-taṇhā) and hatred (vibhava-taṇhā).
These 3 poisons represent the roots of craving (tanha) and are the cause of Dukkha (suffering, pain) and thus result in rebirth.
Interesting that MXTX used this name for one of the characters who suffers, arguably, the worst of these three emotions.
3. The Qian kun purse “乾坤袋 (qián kūn dài) – can be called “Heaven and Earth” Pouch. In Buddhism, Maitreya (मैत्रेय) owns this to store items. It was believed that there was a mythical space inside the bag that could absorb the world.” (TWX)

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.
https://t.co/FBfXhUrH5d
Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.
...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.
Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.
