Change real name on Freenode IRC channel
Hi all. I use the website webchat.freenode.net to access Freenode channels (as a browser tab in Google Chrome). However, when doing a WHOIS on my account, my IP is shown as my real name in the "realname" field. How can I change this? I used to use ChatZilla (under Firefox) previously, and changing the real name was easy using the UI, but since the upgrade to Firefox Quantum (version 57), ChatZilla was disabled. --Meno25 (talk) 12:16, 12 January 2018 (UTC)
 * I highly recommend getting a proper IRC client. I use mIRC.

 * Meno, try Firefox ESR or Waterfox — Preceding unsigned comment added by 78.0.222.210 (talk) 02:56, 19 January 2018 (UTC)


 * Thank you, 78. That's what I needed to know. --Meno25 (talk) 12:00, 19 January 2018 (UTC)

Registry cleanup
I use CleanMyPC Registry Cleaner to clean the registry on my Win 10 (only C disk is present, unpartitioned). It typically finds around 10-20 items to clean during periodic scans, but Avast's Cleanup Premium in the antivirus finds 1,511 entries to clean (with an additional 23,35 GB of claimed redundant data, even though I also regularly do Windows disk cleanup). Which one to trust? My gut says that Avast Cleanup Premium actually exaggerates the real numbers, listing redundant entries. Brandmeistertalk  15:38, 12 January 2018 (UTC)


 * I don't know but you might want to read Registry cleaner. Bubba73 You talkin' to me? 15:57, 12 January 2018 (UTC)
 * {[ec}} Registry cleaners are pointless. They can cause problems and are almost never useful. And Avast's Cleanup finds stuff outside of the registry. I wouldn't recommend using Avast's Cleanup either. &#40;&#40;&#40;The Quixotic Potato&#41;&#41;&#41; (talk) 16:00, 12 January 2018 (UTC)

How to call this type of algorithms?
For a learning project, I wrote a function that checks if the given sentences matches a predefined pattern like, for example:

The name match doesn't provide much information about it. What would be an appropriate name for it? What's the correct way of describing this kind of algorithm? Pattern matching? Grammar matching? Template matching? (I searched for this on Wikipedia but didn't find what I was looking for) --129.45.127.206 (talk) 19:41, 12 January 2018 (UTC)
 * parse v. analyze syntactically by assigning a constituent structure to a sentence, see Parsing. SdrawkcaB99 (talk) 19:54, 12 January 2018 (UTC)

 * The pcode looks like a natural language parser. There are different algorithms for this sort of thing: the Recursive_descent_parser is a common choice, and the article has an implementation in C, so you can see how it works.OldTimeNESter (talk) 02:27, 13 January 2018 (UTC)
