I guess Lee Mack's story on WILTY is believable after all >!although it was a lie in his case!<.

Looks cool! But how loud is it?

There are many that look like this all over Bratislava, Slovakia.

Different tools will have different limits, but some antiviruses consider anything with a compression ratio greater than 90% to be a zip bomb. It isn't difficult to make such a file, just a 4KB file filled with zeroes will have around 178 bytes when zipped, which is a 96% compression ratio. And you can easily do this yourself.

However, this file is not really large enough to be malicious. To be malicious, you'd have to use a larger file. For example, a 1GB zip with that compression ratio would take up 23GB when unzipped, which could easily be seen as malicious depending on the content.

If you want to create an even larger zip bomb, you probably won't have enough space on your system to compress a file, but you would just manually modify the zip structure so that instead of saying 4000 zeroes it says 40000000000000 zeroes. This would give you a compression ratio very close to 100%.

This is what gaffers' tape is designed for. As long as you remove it within a few weeks, there will be no residue. Even leaving it for years is fine (it won't damage anything), you might just have to clean the residue a bit.

Whem you first place the cable, it will want to move around a lot. But you can just pin it down in the corners and remove the tape after a few days. The cable will then remember the shape and won't move around mearly as much.
