Given the occasion, and given that vim is charity-ware software (http://charityware.info/), it would be cool to have some sort of HN-wide donation to ICCF (http://iccf-holland.org/).
Donation page: http://iccf-holland.org/donate.html
It seems that you can send bitcoins too: http://iccf-holland.org/bitcoin.html
Imho just mentioning HN in the payment description would be okay :)
Given Vim powers our industry, it'd be neat if pg or any of the other big members of our community donated a non-trivial amount.
There is very few pieces of software I could never imagine replacing in my toolkit. Linux? I use Windows, too. GCC? Clang gets some love sometimes. Languages themselves? I'm fluent in several. Shell? I used Bash for years, now I switched to ZSH, but could go back to Bash if I needed. Tmux? I could also go back to screen if I needed to.
But vim? There's no replacement for vim. vim changes how you think about programming, how you think about software development. It is this frictionless editor (I mean, yes, huge fucking learning curve, but so is programming in general) that, even 20 years later, I will never abandon (unless I'm doing Java, because... fuck Java outside of Eclipse or IntelliJ; and yes, I've tried using that one vim<->eclipse bridge, hell no).
Re: eclipse. Rather than the bridge you might want to give vrapper (http://vrapper.sourceforge.net/home/) a try. I find it to be quite acceptable - much better than having no vim keybindings. It's very comparable to the jetbrain's vim plugin.
jetbrains vim plugin doesn't even let you define your own vim like keybindings. It is the worst vim plugin I've seen.
