King of Nothing, the DCI paradigm is a scam

I’ve worked on huge applications in Ruby and Rails before. I very much want to believe in DCI, but I’m having a hard time accepting the promises of Clean Ruby when it seems like the work on this paradigm is half-done. If it weren’t so oversold and hyped, I think I’d be more patient, but right now I’m just frustrated and confused.

randym/axlsx · GitHub

Axlsx is an incredible gem to generate "Office Open XML" spreadsheet files (XLSX). Does not break on large spreadsheets and supports a ton of features like graphs.

API looks mature and existing code is easy to migrate when coming from the spreadsheet gem.
The documentation of some methods is a bit out of date, but you'll find your way around the gem's code.

No support for reading files, however. :( If you want to open XLSX spreadsheets (for example to confirm your output in tests), you can use [roo](h…

Force GitHub Pull Requests to update the diff against its target branch

When you have a Pull Request on GitHub that includes commits from another Pull Request, you will still see them after the "child" PR has been merged. Unfortunately, GitHub won't automatically update the diff (or commit list).

Here is what worked for me:

  1. Check out the target branch
    1. git checkout my-target-branch
    2. Make sure you are up to date against origin (e.g. git fetch and git status). You should be 0 commits ahead or behind.
  2. Add and commit a file
    1. touch .please-update
    2. git add .please-update
    3. `gi…

Get Your App Ready for Rails 4

Let’s take a look at what you need to do to get your app ready for Rails 4.

Compare two jQuery objects for equality

Every time you call $(...) jQuery will create a new object. Because of this, comparing two jQuery collections with == will never return true, even when they are wrapping the same native DOM elements:

$('body') == $('body') // false

In order to test if two jQuery objects refer to the same native DOM elements, use is:

var $a = $('body');
var $b = $('body');
$a.is($b); // true

Git blame: How to ignore white-space modifications

When doing a git blame, git will blame the person who added or removed white space in a line (e.g. by indenting), not the person who originally wrote the code.

Say git blame -w to ignore such white-space changes. You want this. \
Note that you can also use it when diffing: git diff -w.

Example

Consider this method, created by a user in commit d47bf443:

def hello
  'world'
end

```text
$ git blame foo
d47bf443 (Arne Hartherz 2012-12-19 14:44:38 +0100 1) def hello
d47bf443 (Arne Hartherz 2012-12-19 14:44:38 +0100 2…

Consul 0.4.2 improves querying of nil powers

Previous versions of Consul exhibited strange behavior when querying a power that returns nil.

Consul 0.4.2+ behaves as expected:

power.notes # => returns nil
power.notes? # => returns false
power.notes! # => raises Consul::Powerless
power.note?(Note.last) # => returns false
power.note!(Note.last) # => raises Consul::Powerless

Why your browser loses cookies when following hyperlinks from an Excel spreadsheet or Word document

Microsoft Office pre-fetches hyperlinks using an internal DLL (which doesn't know about your cookies), follows all redirects and opens your browser with the result. This is because of stupidity.

The "fix" is to not redirect but just render a text like "access denied" with 200 OK when you see that request.env['HTTP_USER_AGENT'].include?('ms-office').

Git: In an (interactive) rebase, find out which commit you are currently working on (until version < 1.7.9.5)

The following stopped working with git version 1.7.9.5 or higher

When you are using git rebase and are currently editing a commit (due to a conflict, for example), you may want to know the current commit. [1]\
Luckily, there is lots of useful stuff in the .git directory.

Commit hash that you are currently applying
cat .git/rebase-merge/stopped-sha

Useful if you want to inspect the original commit for its changes, for example like:

git show `cat .git/rebase-merge/stopped-sha`
Current commit's message
