"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.

This happens because one of the ways I figure out which memory location needs to be modified is by memory-searching for all occurrences and changing the first letter of them
so like if I know the next line of dialog is "Die"
I change it to "Aie" "Bie" "Cie" "Eie" "Fie"
then I see which one shows up in the game
we should apply that logic to the current generation of consoles.
So the Switch is a 256bit console. It's the Nintendo 256.
The Xbox Series X? terrible name.
Better call it the "Xbox 512 Blu-ray".
like the Jaguar CD, the Sega CD... the good old days when consoles had their media type in the name.
Boringly the PS5 is also a Playstation 512 Blu-ray, because both of them are using the same AMD Zen 2 CPU.
The Switch one is weeeird. It's built on an Nvidia Tegra X1, which is an 8 core 64-bit CPU, so that should be 512, right?
Well... no. Four of them can't be used. And later documentation doesn't even mention them.
it's some weird system where the system-on-a-chip has four Cortex-A57 cores and four Cortex-A53 cores but only the A57s are usable?
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.

By 2008, Google had everything going for it w.r.t. Cloud and we should’ve been the market leaders, but we were either too early to market or too late. What did we do wrong? (1) bad timing (2) worse productization & (3) worst GTM.
We were 1st to “containers” (lxc) & container management (Borg) - since '03/04. But Docker took LXC, added cluster management, & launched 1st. Mesosphere launched DCOS. A lot of chairs were thrown around re: google losing this early battle, though K8 won the war, eventually 👏
We were 1st to “serverless” (AppEngine). GAE was our beachhead -- it was the biggest revenue source early on but the world wasn’t ready for serverless primitives. We also didn’t build auxiliary products fast enough. Clients that outgrew GAE wanted “building block” IaaS offerings.
1st to hadoop (map-reduce ‘04) but our hosted Hadoop launched in ‘15. AWS EMR was ~200M ARR by then. 1st to cloud storage (GFS ’03), but didn’t offer a filestore till ‘18! Customers were asking for it since 2014. Didn’t launch archival storage or direct interconnect till v. late.

2. Set your entry routine. I get my students to enter with their microphone muted - you can also not allow attendees to unmute by opening the participants list, clicking the ellipsis and selecting that option.
3. Make sure students arrive as attendees - some organisations have this set up to automatically happen that only meeting organizer is the presenter and others are attendees. Can change this in the manage permissions menu to only me if not already set (opens in a web browser).
4. Classroom routine and expectations - first lesson I share my screen and show the students the raise hand function for when they want to ask questions, how to access the chat function and how to react to questions as opposed to typing answers

Today, there are 500,000 young men missing from the U.S. workforce.
Research suggests video games & improved leisure tech plays a role in the problem. 👇 Thread:
Following the 2007 to 2009 recession, 25 to 34 year old men exited high school with fewer middle-skill job opportunities than years prior.
During this time, we saw an increased number of men living with parents & choosing unemployment over lower paying jobs.
It's estimated that 24M millennials live w/ their parents.
1 in 4 living in their parents’ home neither go to school nor work.
What's more surprising? 9 in 10 who lived with their parents a year ago are still living there w/ no plans to leave.
Economists are calling millennial men a lost generation.
According to economist David Dorn:
“If you get to the point where you’re turning 30, you’ve never held a real job and you don’t have a college education, then it is very hard to recover at that point.”
Economists suggest this choosiness is a generational trait.

Here is the thread of practical advice for you.
EXAMINE YOUR MOTIVES. Why do you want to write this?
Are you trying to solve racism/sexism/colonialism with your work?
As writers we love stories about heroic writers whose work has changed the world. And as such we like to look to our own writing to solve societal problems.
And I understand this completely, not the least because I’ve felt the pull.
But if you’re looking to play saviour with your words, it is unlikely that you will do the marginalised people you are trying to save justice.
And I understand this very often comes from place of good intentions, but there is a reason that most of the moralising plays written by white abolitionists are deeply uncomfortable to read.
It is incredibly easy for works looking to play saviour to become patronising or traffic in simplistic stereotypes that ultimately hurt the people they are looking to rescue.
