Dear user:subh, cleaning up is not vandalism. Please see that all my edits were legit. In your blind revert, you have removed some cited material also. I think that removal of refs will come under vandalism. Please discuss it in talk page-Bharatveer (talk) 09:23, 5 November 2008 (UTC)

Edits of User:Sshontu at Kolkata article

Help: Kolkata
Hi Subh83!! Please help updating the article Kolkata, because useless information with improper English has been added on the second paragraph by User:Kkm010. Actually, I don’t know much about the history of Kolkata, so I want you update it. I have corrected most of the grammatical errors on the second paragraph. (Since that’s a featured article I am giving a notice to some of the Bengali editors.) Thanks!  Gui tar ist ( talk| contributions) June 29, 2024

sorry for the edit conflict, i'd just been writing that for last hour since it was longer i thought we could edit and merge both our contributions together in that collection of material. Paintedxbird (talk) 23:51, 2 March 2012 (UTC)
 * No problem. Yours appear much better and well-written. So we can keep it that way. - Subh83 (talk &#124; contribs) 23:55, 2 March 2012 (UTC)

Invitation to events in June and July: bot, script, template, and Gadget makers wanted
I invite you to the yearly Berlin hackathon. It's 1-3 June and registration is now open. If you need financial assistance or help with visa or hotel, just mention it in the registration form.

This is the premier event for the MediaWiki and Wikimedia technical community. We'll be hacking, designing, and socialising, primarily talking about ResourceLoader and Gadgets (extending functionality with JavaScript), the switch to Lua for templates, Wikidata, and Wikimedia Labs.

Our goals for the event are to bring 100-150 people together, including lots of people who have not attended such events before. User scripts, gadgets, API use, Toolserver, Wikimedia Labs, mobile, structured data, templates -- if you are into any of these things, we want you to come!

I also thought you might want to know about other upcoming events where you can learn more about MediaWiki customization and development, how to best use the web API for bots, and various upcoming features and changes. We'd love to have power users, bot maintainers and writers, and template makers at these events so we can all learn from each other and chat about what needs doing.

Check out the the developers' days preceding Wikimania in July in Washington, DC and our other events.

Best wishes! - Sumana Harihareswara, Wikimedia Foundation's Volunteer Development Coordinator. Please reply on my talk page, here or at mediawiki.org. Sumana Harihareswara, Wikimedia Foundation Volunteer Development Coordinator 15:08, 2 April 2012 (UTC)

on the homotopy page you wrote:

"Finally, and most importantly, a clear clarification of the difference between two spaces being "homotopic" vs. them being "homotopy equivalent" is important to avoid confusion."

but this is a mistake: there is NO difference between the concepts: "being homotopic" and "being homotopy equivalent", isn't it?--131.114.73.16 (talk) 14:06, 29 January 2013 (UTC)


 * "Homotopy" is defined for maps (continuous functions). While "homotopy equivalence" is defined for topological spaces.


 * Thus, "a disk is homotopy equivalent to a point", or a "an annular ring is homotopy equivalent to a circle". You don't need an embedding to talk about the homotopy equivalence between topological spaces. Topological spaces that are homotopy equivalent are also said to have the same homotopy type.


 * On the other hand, homotopy, being a notion associated with maps/functions, is often used to describe relationship between embeddings. Thus, one can talk about two circles being homotopic on $$\mathbb{R}^2-\{0\}$$ (i.e., it's a relationship between the embeddings of the circles: $$f_1,f_2:\mathbb{S}^1\rightarrow \mathbb{R}^2-\{0\}$$). However, one does not say "a disk is homotopic to a point".


 * So no, they are not the same.- Subh83 (talk &#124; contribs) 06:28, 31 January 2013 (UTC)
 * mmh ok.. in THIS sense they are different. Thank you for your contributions on the homotopy page--131.114.73.16 (talk) 17:02, 9 February 2013 (UTC)
