Error correction is incredible

A link to the full video is at the bottom of the screen.

The full video tries to make you feel like you could have invented Hamming codes. (On most shorts players, the link should be at the bottom of the screen)

[Julzaa]

Such a delight to remember the cleverness of your videos through your shorts, makes me want to watch them again

**Teases us with knowledge**
**Slowly fades away***

I feel like mordecai is narrating this

[greeeenchee]

The binary code that is show in the middle of the video translates to “you’re wasting your time”, nice touch.

Meanwhile: My CD with a single minor scratch— *cannot read disk*

[Paul-sjdb]

The original CD could handle a hole being drilled in it. They reduced the error recovery capacity in order to increase the storage.

Bro's voice fading away at the end really cracked me up.

[ecospider]

This is one reason a cd can store more data as a music cd. The error correction doesn’t take as much space

[PythogorasBC]

I was honored to have Prof. Hamming teaching me and my classmates. When he presented his brilliant method for correcting errors he commented: "simple, isn't it?", obviously the classroom was shaking by our laugh and clapping.
I feel so lucky, so lucky to have shaked hands with that important person and mainly HUMAN being.
Respect, absolute respect.

Hamming codes are really neat - despite being a really old concept, you can detect up to two errors and even correct an error bit. Also they use the channel capacity really efficiently being referred to as "perfect codes", and they're very easy to implement. We used them at CERN for diagnostics for some of the safety systems as we had low bandwidth for our distributed systems

I think it's way more important to mention that the actual data isn't stored on the surface of the CD, but on the reflective layer about 1mm below the surface.
These bumps in the material change the focus of the reading laser, making it possible to decode 1s and 0s. This also means that, unless the CD is scratched so heavily that it becomes impossible to differentiate between the bump and not-bump, the data is unaffected.

Affecting the data layer directly is essentially impossible to do unintentionally without breaking the CD entirely.

That was a brilliant way to get me off shorts and on to the full length video. I loved it too.

[ShubhamShubhra]

Learned about Hamming Code in my electronics engineering, but, I understood onky after watching your videos. As always, amazing work.

My phone screen has a scratch so I saw a scratched CD decode into a scratched Mona Lisa

[MXvsATVnovice]

Just so tough to hit the nail on the head when it comes to video length given the nature of your content.

Makes want more.

Reminds me that sometimes stuff is actually complex and requires time to understand even in a compressed format let alone full breadth

[ryanthescion]

Of all my college classes coding theory was by far the hardest for me to wrap my head around

[nblank]

I didn't know it was possible to be edged by 1-0s knowledge

[anorangewithacapybaraunder]

My ps2 & ps3 game cds had a tough life lmao. But true to the saying, when the going gets tough, the tough get going because they never skipped a beat despite the abuse

[MountainPieEnjoyer]

*Scratches CD just right*
*Finds government top secret documents*
