Tweets
Looking for tweets for deprecate.

jjackel elgiad007 is on the right track. In computer programming, deprecated means that the developer of a framework will no longer support a particular function or method. It does not necessarily mean there is a direct replacement. Sometimes the developer takes a completely different approach to a problem. Nonetheless, a deprecated method often continues to work for a time. When the developer declares a method deprecated, s/he is explicitly breaking the implied contract that new versions of a framework will work with older programs, preparing programmers and users for the possibility that their stuff may no longer work or may stop working someday.

bilby I finally found an example of the usage elgiad is referring to:
"Amazon Ecommerce Web Service 3.0 has been deprecated after many years of useful service on March 31st 2008. Please upgrade to the Amazon Associates Web Service 4.0 as detailed in the migration guide."

elgiad007 This word is commonly used to describe computer programs or library functions that have been replaced by newer or better versions (I use the logical operator "or" here to point out that a new version does not denote a better one, as in the case of some Microsoft Windows upgrades).

chained_bear Stop marginalizing my discourse.
(Joke alert!) Aug 15, 2008
whichbe Depreciate sounds so dramatic, like getting bescumbered. "Yer ass got depreciated!" Aug 15, 2008
super-logos I think deprecate means to affirmatively put someone or something down. It is not a bagatelle. I think one deprecates when one stands up in a crowd to denounce something or when one is in a public forum, such as a newspaper. It is an ongoing repudiation. To depreciate is to devalue or go down. A stock can depreciate in value. Aug 15, 2008
milosrdenstvi Because I generally use it more in the sense of "I don't think so" instead of "that's WRONG!" Aug 15, 2008
chained_bear I'm going to appropriate that. Why do you think it veers off into depreciate? It seems like it's used just dandily.
The phrase reminds me of a class I was in once, in which one student complained that another was "marginalizing my discourse." Aug 15, 2008
milosrdenstvi Totally awesome in the form "I deprecate the validity of that assertion." (Technically that's more the territory of depreciate, but I've sort of merged the two words into the one that sounds good.) Aug 15, 2008
