Coding 100% of my time on a laptop I noticed that I sit wrong and my spine is always bent. So I bought this amazing thing to fix this:

By now the experiment is OK – I feel really good, sit right with monitor in front of my eyes. What do you do to be a healthy coder?

Since I started using Gistflow — which I think is a superb application, by the way — I have accumulated a few #questions regarding some of the #features, #uses, workings, #quirks and various other things. I'll post my personal #FAQ questions here as I think of them.

Note: this post is likely to be edited/updated regularly. It's just that sort of post, don't feel bad. More under the cut

As we know we don't see scrolls on #OSX Lion and above by default, but sometimes we have to show them to user because of #UX.

We can do it just by adding scroll's styles. For example:

#myelement::-webkit-scrollbar {
  -webkit-appearance: none;
  width: 8px;
}

#myelement::-webkit-scrollbar-track {
  background-color: #eee;
  border-radius: 8px;
}
#myelement::-webkit-scrollbar-thumb {
  border-radius: 8px;
  background-color: #666;
}

#html

for(var i=0; i<googletag.debug_log.H.length; i++) {
  console.debug(googletag.debug_log.H[i]);
}

#javascript #dfp #googleadmanager

//...
NSData *somedata = ...
for (int i = 0; i < [somedata length]; i++) {
    const uint8_t * databytes = [somedata bytes];
    [self getBitStringForInt:(uint8_t)databytes[i]];
}
//...

- (void)getBitStringForInt:(int)value {
    NSString *bits = @"";
    for(int i = 0; i < 8; i ++) {
        bits = [NSString stringWithFormat:@"%i%@", value & (1 << i) ? 1 : 0, bits];
    }
    NSLog(@"%@", bits);
}

When contributing to open source you may face a problem – your fork is outdated. There could be another scenario – git repo in Github is just mirror of perforce repo, so after your pull request is merged there won't be your commits in repo and you again will have to sync fork and origin.

git remote add upstream git://github.com/username/repo.git
git fetch upstream
git checkout master
git reset --hard upstream/master  
git push origin master --force

Given an image accessor field cover_image for an Image model, u can use a cover_image_url accessor for assigning directly from a url (simply using a string). To make it does what u want just save the corresponding object.

example:

img = Image.new
img.cover_image_url = 'http://img.youtube.com/vi/wh-XcmRQFhI/0.jpg'
img.save

BTW: what is your favourite image uploader in rails?

I have a lot of code in my project like the following:

class Animal < ActiveRecord::Base
  state_machine do
    around_transition :on => :sure do |animal, _, block|
      animal.transaction do
        block.call
        animal.do_things_on_sure
      end
    end
  end
end

around_transition looks ugly and repeats for many classes.. Lets refactor it. More under the cut
