Software Bugs That Caused DISASTERS

Dive into the profound impact of software bugs on our interconnected 21st-century world, where lines of code dictate crucial services like healthcare, traffic, and military operations. Explore how the binary realm of ones and zeros can alter destinies, sometimes for the worse.

From Grace Murray Hopper's discovery of a moth in the Harvard Mark II computer, which birthed the term "bug," to its evolution into flaws in computer programs, discover the ripple effect of these bugs beyond the digital sphere.

Wow, I still cant believe how well this video is performing! When I was uploading it, I was hoping for like 100 views max and here we are, almost at 5000! Thank you so much! Just so you know I have been working on a new video for the past couple of weeks and I’m very excited to share it with you guys when it’s ready! It’s going to be about a notorious hacker…

Matt Parker's, from Stand Up Maths and Numberphile, wife actually worked on the Ariane 5 I believe, and he has spoken in depth about it a few times. Not only was the code not proper, it wasnt even necessary for the sensor to be active when it failed and was only still on to help reduce restart time if the launch was aborted

re Grace Hopper, first bug: Last I checked (which was admittedly a long time ago) there is a lot of dispute about that "first bug" story. I mean: no one doubts that a physical bug was found or that it caused problems. And it makes for a very humorous story.

But when you try to peg this as the actual origin of this usage of the term "bug" to mean "error in a computer program's logic", from what I've read, it doesn't necessarily check out.

this video is surprsingly well edited for such a small channel. you deserve way more subs. will definitely share this with friends!

5:58 Not sure how old you are, but the y2k bug got exactly the right amount of attention. Because of all that "panic" everybody and their aunt tested what will happen when the computer clocks switched to 2000. Bugs were fixed, companies were prepared, CEOs made sure this is on the top of the lists etc. And the fact that those type of bugs are still around - e.g. GPS week rollover, Y2K38 bug - shows that the panic back then wasn't big enough...

Programmer here. Your image for "maximum value" at 1:56 shows all 16 bits as being "1". But for a 16-bit signed integer (in the 2-complement which is by far the most common representation of signed integers in memory), the max value is reached when the most significant bit (for this purpose: the left-most) is "0", only the other 15 bits are "1". "All bits 1" would the representation of a "-1".

couple typos (7:00), but still a really good, well made informative video!

jesus i thought this video was from a verified channel for a bit, you are EXTREMELY underrated. Please keep up the good work! This is a really good video

At 6:36 the video claims that a software bug in the first gulf war, 1999 was lethal. The war was called "Dessert Storm" and started on January 17th 1991. Better check your computer mate, and the factual sources, you might have a bug in your system😜

[jdrissel]

I woul have thought that the Therac-25 would be on this list...

[phantomaviator]

babe wake up new essay youtuber dropped

[still.rendering]

Great video! Love the editing and how the stories were put together

[SteveChisnall]

the THERAC 25 is conspicuously absent from your list.

[lgackey]

whoa! amazing video! i love the production quality, from the editing and stylistic choices to the subject material, this rules! keep up the great work!

[BigBoyDuckie]

this popped up in my recommended, good vid man. subbed

[Camobiwon]

Very well made video dude! Got it randomly in my recommended and am always shocked when I get videos like this and how small the channel / view count it. Keep it up :)

At 5:50 I heard it was fifty cents a day for a century, $18, 250. Was it $2.50 a day?

It's incomprehensible that your channel has only 914 subscribers, editing is superb & it's visible that you posses technical background when explaining terminology, btw. are you from somewhere in eastern europe? I can approximate because I've got similar accent

[tristantheoofer]

you have only 100 subs wtf? for a channel this size this is actually pretty well edited actually

[bdnugget]

Good videos! I got reccommended the Terry Davis one, subscribed and watched all the other ones after that
