Vi niceties

This last Railsberry there was a very fine Vim introduction/advocacy speech by Ben Orenstein from vimuniversity.com (yes, go check now, I'll wait)


There were plenty of vim showoff there on the talk, but one of the neat tricks caught my eye, and today I have used it for the first time, so here it is for you all to discover and hopefully for me to remember:

Vim Macro's Surgery:

Macros are one of Vim's most famous and least used (by beginners) features. As you progress along the path of Vi/m you start using them more often to avoid repetitive chores and menial tasks.


So far so good, but until now, if I was making a macro and got wrog, I had to start over and record a new one, Ben showed us better:

  • Record a Macro into the 'a' register:
    qa<...commands...>q
  • Paste it:
    "ap 
  • Correct:
    <...macro editing...>
  • Yank it again:
    0"ay$
  • Use it:
    @a 
  • Or use it 42 times
    42@a

On a side note, what I was doing today was edit teh configuration for a new pluging I saw at vim.org. It is called CtrlP ang gets right everything control-t and Fuffile got wrong, so I recomend you to give it a try. You might need to tweak uo the highlights, depending on your colorscheme, so I leave the relevant doc reference here for your convenience:

===============================================================================

Railsberrying

The second day of Railsberry came and exploded in all its glory. The concerns I had the first day, mainly about the dimension vanished as the event fitted in place.

This second day was crazy and amazing. Linda Liukas talk about Rails Girls project and Xavier Noria's talk about Rails Contributors were both really touching and remembered me about how special is this communnity.

Yehuda Katz gave a very interesting speech about different kinds of unknowns and how the framework should take care about them to leave the developer the creative part of the task. With it he deffended Rails versus suposedly faster or lighter approaches.

Josh Kalderimis talked about crowdfunding experience with Travis-CI in yet another example of people giving away just to makes others' lives better.

Aaron Patterson gave a hug to everybody before he start talking about his homemade pepperoni curating device which finally was an elaborated fable about the tight coupling.

Railsberry is awesome, but...

The first day of RailsBerry came and went. It was really awesome for the most of it but find it difficult to concentrate on the awesome part throught the fact tha wi-fi was crappy for most of the people and non-existant for me.

It is very sad to be in such a social and real-time event as a conferente and not be able to share your thoughts, read what others say on twitter, and so on.

The little details that make a conference great are there, it has good speakers, original and lovecrafted image and theme, unlimited coffee, parties, food, coke, whatever.

Safe and sound at Krakow

After getting up absurdly early and a just standarly uncomfortable flight with ryanair I have arrived at Kraków to attend www.railsberry.com

I am very happy to be back at this beautiful city and to have some abroad action that I will lack in the upcoming months.

There won't be Euruko for me this year and the Conferencia Rails has evolved to a js centered frontend event , so this is going to be The Rails/Ruby event this year.

I hope to see a lot of people from the Spanish Ruby community that are currently living abroad and update on some interesting Rails matters.
