I'll add mine: https://brage.info/hello

It's a 1MB file that decompresses to 261 tredecillion bytes of "Hello, World".

No terribly clever stream manipulation; it's a perfectly normal gzip file, other than the size. The generation script is here: http://sprunge.us/VhFc, but see if you can figure it out without peeking.

Warning to my fellow chumps: that is a direct link to the gzip bomb. Clicking on it causes a download, which results in Windows Defender promptly losing its mind as it tries to decompress the whole thing looking for viruses. (win 8.1)

Interestingly enough, it's not using up any memory, but it is hitting the disk at 55MB/s, so I'm guessing it's decompressing it to disk, and will eventually crash when it fills up my hard drive.

EDIT: It gave up after fifteen minutes. That's nice, now I don't have to reboot. There was about 2 gigabytes of stuff in my temp folder when I ran disk cleanup, don't know how much of that was gzip bomb output.

May I suggest for the merely curious:

    curl https://brage.info/hello | od -c | head -40

Is that short or long scale tredecillion?

Actually, it decompresses into a 1.4MiB file, which decompresses into another 1.4MiB file, recursively.

I sized it to fit on a floppy disk. :-3

But, no. There's a finite number of levels, and it blows up pretty quickly.
