If you try to create a test user on AWS Cognito using console, it will be created in status set to FORCE_CHANGE_PASSWORD. With that value, this user cannot be used.

To change its password you have to enable ADMIN_NO_SRP_AUTH for the chosen client-id (without secret key) and execute the two commands:

aws cognito-idp admin-initiate-auth --user-pool-id <user_pool_id> --client-id <app_client_id> --auth-flow ADMIN_NO_SRP_AUTH --auth-parameters USERNAME=<username>,PASSWORD=<current-password>

1. Break the app into components

2. Build a static version of the app

3. Determine what should be stateful

4. Determine in which component each piece of state belongs

5. Hardcode initial status

6. Add inverse data flow

If you are having trouble skipping CAS Client filter inside a Rails app, wrap the call to CAS filter in a protected method and skip_before_filter starts to works

class ApplicationController < ActionController::Base  before_filter :cas_filter  def cas_filter    CASClient::Frameworks::Rails::Filter.filter(self)  end end class UnprotectedController < ApplicationController  skip_before_filter :cas_filter end 

I really don’t like Resque because we had so many issues with it, but I’ve got to manage some workers that are still using it.

I always forget how to launch resque-web, so just to avoid my mental insanity, here is the right way to tell which redis database to use in the command line:

This article on Angular transclusion by @teropa is really awesome

“Unit testing and mocking AngularJs requires a lot of boilerplate code.

ng-describe makes testing simple modules a breeze. Just list which modules you would like to load, which values / services / etc. you would like to inject and then start testing. 

ng-describe can inject dependencies, mock modules, set configs, create controllers, scopes, and even html fragments.”

Great post to learn how to easily manage control flow in asynchronous javascript applications

I’m a Ruby fan and I always use rvm to manage different ruby environment in the same machine.

Something similar exists for node! It is called nvm for Node Version Manager. 

Here is a great tutorial!

I had some issue with a git report on my laptop, so I decided to restore it from the Time Machine.

I restored the last working backup, but when I try out some git commands, the repo seems to be damaged and it won't works anymore.

fatal: unable to read 4a0dbcbaa0287ff8fc7a91c75ab1eadfe2f8c548

and the results of  git fsck was full of missing references

Dammn! But after some retries, I found out a working solution:

I clone the remote repository in a ../new folder

Then in the broken repostory I did

cat ../new/.git/objects/pack/pack-*.pack | git unpack-objects

This filled up the missing objects in the object database and the repository seems to be fixed.

Suddenly my MacBook Pro's "o" key stopped working... 

What the hell is going on? 

I don't know, but I found here the answer:

If you need to install a gem straight from its github repository you may use specific_install:

The mongoid gem that supports Rails 4 hasn't been published yet so you have to download it directly from their Github repository. 

To get browser's user language settings you should use $window.

There is an Angular service called $locale which should provide this information, but currently it seems to be hard coded in each angular-i18n local file.

One of our workers uploads files to an S3 bucket, but due to a strange BUG, it uploaded a file using a wrong path with a double slash:

/bucket/folder//filename

The file automagically become invisible to AWS dashboard and to Cyberduck, but it was here, I knew it was here!

I'd like to delete this file, but no way out with Cyberduck or AWS S3 dashboard. The file seems to be vanished..

So the easy way to find and delete hidden file with double slashes in the name is to use s3cmd tools.

s3cmd --configure s3cmd ls s3://bucket/folder//filename s3cmd del s3://bucket/folder//filename

and the file will be removed from the S3 bucket

s3cmd ls s3://bucket/folder//filename

now returns nothing.
