CRC-8-CCITT
Hello Ralf, do you happen to have a citation for the polynomial $$x^8 + x^7 + x^3 + x^2 + 1$$ you contributed to the Cyclic redundancy check page in 2006? It seems doubtful that the 1-Wire Bus would use two polynomials of the same length. On the plus side, I'd find any literature you do track down very useful. Thanks. – Regregex (talk) 18:33, 4 December 2009 (UTC)

CRC-8
It's all even worse. That edit is over three years old so I went to re-research it.

I think I figured out why I thought the polynomial was $$x^8 + x^7 + x^3 + x^2 + 1$$. I went through Dallas' documentation and they all consistently use $$x^8 + x^5 + x^4 + 1$$. I also found $$x^8 + x^2 + x + 1$$ in the ITU-T I.432.1 (02/99) specification so I'll throw that into the CRC article. —Preceding unsigned comment added by Ralf.Baechle (talk • contribs) 02:24, 24 December 2009 (UTC)

Your account will be renamed
Hello,

The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. See the announcement for more information.

Unfortunately, your account clashes with another account also called Ralf.Baechle. To make sure that both of you can use all Wikimedia projects in future, we have reserved the name Ralf.Baechle~enwiki that only you will have. If you like it, you don't have to do anything. If you do not like it, you can pick out a different name. If you think you might own all of the accounts with this name and this message is in error, please visit Special:MergeAccount to check and attach all of your accounts to prevent them from being renamed.

Your account will still work as before, and you will be credited for all your edits made so far, but you will have to use the new account name when you log in.

Sorry for the inconvenience.

Yours, Keegan Peterzell Community Liaison, Wikimedia Foundation 02:17, 20 March 2015 (UTC)
