We need to figure out how to handle general code improvements / technical debt fixes that come up while working on a feature.
The workflow we have adopted is to use 'develop' as the main integration branch and develop all features on feature branches off of 'develop'. When a feature is complete, the developer creates a pull request and everyone reviews it to provide comments before it is merged back into develop. This seems to be working very well.
The issue we have is that during routine development on a feature, the developer may end up wanting to modify/refactor some common code to improve the system or clean up some technical debt. This change is valuable, but not directly tied to the feature under development.
Based on our workflow, it should really be done on a different branch that goes through it's own pull request and code review before getting into develop. If we have them do this though, how can they get the change back over onto their feature branch in the meantime while they wait for the full code review to happen and the code to get merged into develop.
The ideas we have are:
1) cherry-pick the changes from the 'refactorX' branch into our feature branch. Continue developing and let git (hopefully) figure out when we merge back to develop that it already has the change from the refactor branch.
2) Merge the 'refactorX' branch into our feature branch and continue development. (note: the branch off develop for 'refactorX' may have been later in the history of develop, so we think this may have problems)
3) Some other smarter option we don't know yet. :)
What we are looking for is some best practice guidance on how to handle this part of the workflow. After talking about it more we know that it will come up frequently and we want to find a smooth and efficient way to handle it in our workflow.

| android | video | delete | android-intent | uri | null | open | How deleting a recorded video with ACTION_VIDEO_CAPTURE
===
I would like to remove a video that has been previously recorded using an Intent:
Intent captureVideoIntent = new Intent(
android.provider.MediaStore.ACTION_VIDEO_CAPTURE);
startActivityForResult(captureVideoIntent, VIDEO_CAPTURED);
The method onActivityResult() get the recorded video as Intent data. I try to obtain the recorded file and delete it.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
try {
Uri uri = data.getData();
File file = new File(uri.toString());
file.delete();
} catch (Exception e) {
e.printStackTrace();
}
}
No errors are shown in logcat but the file is not deleted.

Looking to try a useful app now. Was looking for ideas and my wife suggested doing something that would warn people there are Amber Alerts. Quick search reveals there is one already, but it is based on ios 2.0, before PUSH notification, so user has to check the app to know if there is an Amber Alert. So not very useful for the purpose, would like to update it and provide it to the Amber Alert people for free.
Link to original app (with useful screenshots):

I am looking to extend the app beyond the original, but I like how it currently lets you view missing children. Looks like it uses this database:
http://www.ncmec.org/missingkids/servlet/PubCaseSearchServlet
I'm brand new to this, so it feels like I'm drinking from a firehose on trying to figure out how the user might have done this (there may be dozens). I don't have access to the server involved, and obviously no change is really needed since it works for the original app. Just looking for some possibilities on how I might send data to a web server that I don't control, with effectively form data, and take the response and filter it. High level responses are welcome, I'd like to research the details, just not sure where to start.

EXCEPT that I want the result to be a MovieList itself, whereas this returns an array of Movies. So I could do, for example:
list = User.first.movie_list.for_year(1999)
list.id # would give the id of the MovieList = User.first.movie_list.id
list.movies.first.id # would give the id of the first movie in list
I have a feeling that I'm either a) faced with this problem because my design is bad, and it would be great if someone could explain how I *should* design this, or b) asking for something relatively mundane but I just don't know the right terminology.

A B C
1 {2, 0, 2}
2 {1, 0, 1}
A couple of terms that will be used in the problem:
A ***pair*** is a pair of a letter and a number. The number always comes first. Each pair is basically an index to an element. (e.g. **1A** = 2, **2B** = 0, **1C** = 2, etc.).
A ***command*** is a pair of two pairs. The "syntax" is [*sourcePair*][*destinationPair*]. **The *sourcePair* always has to be a non-zero value while the *destinationPair* always has to be a zero value. This of course also prevents you from using the same pair as the *sourcePair* and the *destinationPair*.** It works like this: whatever value is in the *sourcePair* (either 1 or 2) will be moved into the *destinationPair* and then the *sourcePair* will be set to 0 (it will modify the matrix). (e.g. **1A1B** -> 1B = 2, 1A = 0; **1C2B** -> 2B = 2, 1C = 0; etc.).
A ***key*** is a set of 16 commands (64 characters in total).
***GOAL***: To find all of the possible combinations for the key that will make the matrix look like this:
A B C
1 {1, 0, 1}
2 {2, 0, 2}
The rows of the matrix are basically swapped. The algorithm doesn't have to be super-efficient as I will only be printing the key when the user presses a button. Also the key has to be **exactly** 16 commands long (64 characters). It doesn't matter if you for example use the first x commands to do something just to occupy some space and then use y commands to do the actual thing.

});
In this sample, the JSON data comes back fine -- "App.WindowDetail.InteriorFinishesDescription" gets populated.
The problem is that the template doesn't get populated. And, I don't think this is exactly the correct way to get JSON data back when using Ember JS.
Here's a sample of what the handlebars template looks like:
<script type="text/x-handlebars">
<div class="two columns">
{{App.WindowDetail.InteriorFinishesDescription}}
</div>

===
I'm trying to analyse a ~800mb heap dump, which requires a bigger heap than the standard for my eclipse. however, when I go to the eclipse.ini file and set a ``-Xmx2g`` (or ``-Xmx2048m``) I get an error "Failed to create the Java Virtual Machine".
1) yes, I have enough memory. 2) I can change it up to exactly -Xmx976m. 3) I've tried the standalone MAT analyser and it works with -Xmx1024m, not a byte more. 4) No, 1gb is not enough to analyse that heap, I get a OOM
This is the eclipse error:
![alt text][1]
This is the MAT error:
![alt text][2]
(I reckon they are the same, this is just so you can see an example with MAT)
My current eclipse.ini (working) is:

I want to add an admin-user that has some additional abilities, but I will be the only admin user (or admin users can be created via terminal - ie people cannot sign up to be admin users). All regular users have the same abilities. I was just about to use cancan to separate abilities based on user roles. Then it occurred to me that using cancan may just be overkill. does it make sense to just create a different class of user instead? Am I giving anything up by doing this?
I can foresee in the future that if this app is successful, there may be different roles for users (a free versus paid account, etc). Even in that case, does it make sense to NOT have an admin user via devise? Thoughts?

- An `owner` can have many `pets`
- A `pet` can have one `owner`
- A `pet` can be treated by (belongs_to) many `veterinarians`
- A `veterinarian` can treat (have_many) `pets`
`Owner` and `Veterinarian` are both subclasses of `User` using STI.
Here's some code:
class Owner < User
has_many :pets
has_many :veterinarians, :through => :pets
end
class Veterinarian < User
attr_accessible :clinic_name
has_many :pets
has_many :owners, :through => :pets
end
class Pet < ActiveRecord::Base
attr_accessible :name, :date_of_birth, :species, :breed, :gender, :neutered
belongs_to :owner
belongs_to :veterinarian
end
And here is the spec that is failing:
it "has various veterinarians" do
o = Owner.make!(:email => 'owner1@gmail.com')
v1 = Veterinarian.make!(:email => 'vet_1@gmail.com')
v2 = Veterinarian.make!(:email => 'vet_2@gmail.com')
p = Pet.make!(:name => 'fluffy')
o.pets << p
v1.pets << p
v2.pets << p
o.pets.should have(2).records
o.veterinarians.should have(2).records
end
The `make!` stuff is to do with using machinist fixture replacement. It just factory creates the objects.
The failure occurs on the last line. It turns out that o.veterinarians only has 1 record. I understand that a `pet` is not a join table in the traditional sense, inasmuch as I don't want to create a whole new pet each time I create a relationship between an owner and a veterinarian. Should I be using a schema more like `Owner` has_many `Pet`s, `Pet` belongs_to :owner and `Pet` has_and_belongs_to_many `Veterinarian`s?

Or other.. | I'm currently working on a system that in some cases will need to run on a local database during the day, and then replicated to a central server during the night. It *cannot* all run from one central database as the local sites are out of contact with it periodically. The data at the central server is for viewing and reporting only at head office, so nothing needs to be reverse replicated back to the site.
Each "site" is given a text based unique key (human generated). However, the thought of making every table in the database design reference the site key is not appealing.
Here's an example of a very cut back version of the schema *without* worrying about remote replication (which will work fine for the majority of clients) : -
(I'll only show the history table for the Area table, to keep things short) :
[Site]
SiteKey [PK] (Gauranteed 100% unique across all sites text based key)
[User]
SiteKey [FK -> Site]
UserID [PK]
[Area]
SiteKey [FK -> Site]
AreaID [PK]
Description
UpdatedDtm
UpdatedUserID [FK -> User]
[AreaHistory]
Site [FK -> Site]
AreaID [FK -> Area]
Description
UpdatedDtm
UpdatedUserID [FK -> User]
AuditedDtm
[Location]
AreaID [FK -> Area]
LocationID [PK]
Description
UpdatedDtm
UpdatedUserID [FK -> User]
[Sensor]
LocationID [PK / FK -> Location]
SensorNo [PK]
UpdatedDtm
UpdatedUserID [FK -> User]
[Reading]
LocationID [PK / FK -> Sensor]
SensorNo [PK / FK -> Sensor]
ReadingDtm [PK]
Which is fine, until I come to "merge" the database with the database at the central server. I'm obviously going to get clashes in the Location table because I'm mixing data with ID's generated at other sites.
The first way I thought around this problem was to do this:
gs short) :
[Location]
SiteKey [FK -> Location, FK -> User] ** ADDED THIS
AreaID [FK -> Area]
LocationID [PK]
Description
UpdatedDtm
UpdatedUserID [FK -> User]
[Sensor]
SiteKey [FK -> Location, FK -> User] ** ADDED THIS
LocationID [PK / FK -> Location]
SensorNo [PK]
UpdatedDtm
UpdatedUserID [FK -> User]
[Reading]
SiteKey [FK -> Sensor] ** ADDED THIS
LocationID [PK / FK -> Sensor]
SensorNo [PK / FK -> Sensor]
ReadingDtm [PK]
Basically, every table gets a SiteKey making each row unique to the site.
An alternative is this (using UUIDs in some places) : -
[User]
SiteKey [FK -> Site]
UserUUID [PK]
[Area]
SiteKey [FK -> Site]
AreaUUID [PK]

UpdatedDtm
UpdatedUserUUID [FK -> User]
[AreaHistory]

Remember this is cut down, but it illustrates the problem.
Are there any alternatives I may be missing? I thought about ID remapping but that seemed to introduce new even worse nightmares.
The annoying part of this is that it's a very small number of cases that use this scenario, the rest are happy with one database serving many sites. However, the client wanting this scenario is the biggest ;-)
I thought maybe I could use UUID just for them, but that means creating exceptions everywhere so may as well just use them throughout (where neccessary) if I'm going to use them.
If it makes any difference, I'm using PostgreSQL.
PS, [this][1] discussion may be relevant to this case. I just keep wondering if there's another way considering I have a nice gauranteed unique SiteKey.

I'm currently working on a system that in some cases will need to run on a local database during the day, and then replicated to a central server during the night. It *cannot* all run from one central database as the local sites are out of contact with it periodically. The data at the central server is for viewing and reporting only at head office, so nothing needs to be reverse replicated back to the site.
Each "site" is given a text based unique key (human generated). However, the thought of making every table in the database design reference the site key is not appealing.
Here's an example of a very cut back version of the schema *without* worrying about remote replication (which will work fine for the majority of clients) : -
(I'll only show the history table for the Area table, to keep things short) :
[Site]
SiteKey [PK] (Gauranteed 100% unique across all sites text based key)
[User]
SiteKey [FK -> Site]
UserID [PK]
[Area]
SiteKey [FK -> Site]
AreaID [PK]
Description
UpdatedDtm
UpdatedUserID [FK -> User]
[AreaHistory]
Site [FK -> Site]
AreaID [FK -> Area]
Description
UpdatedDtm
UpdatedUserID [FK -> User]
AuditedDtm
[Location]
AreaID [FK -> Area]
LocationID [PK]
Description
UpdatedDtm
UpdatedUserID [FK -> User]
[Sensor]
LocationID [PK / FK -> Location]
SensorNo [PK]
UpdatedDtm
UpdatedUserID [FK -> User]
[Reading]
LocationID [PK / FK -> Sensor]
SensorNo [PK / FK -> Sensor]
ReadingDtm [PK]
Which is fine, until I come to "merge" the database with the database at the central server. I'm obviously going to get clashes in the Location table because I'm mixing data with ID's generated at other sites.
The first way I thought around this problem was to do this:
gs short) :
[Location]
SiteKey [FK -> Location, FK -> User] ** ADDED THIS
AreaID [FK -> Area]
LocationID [PK]
Description
UpdatedDtm
UpdatedUserID [FK -> User]
[Sensor]
SiteKey [FK -> Location, FK -> User] ** ADDED THIS
LocationID [PK / FK -> Location]
SensorNo [PK]
UpdatedDtm
UpdatedUserID [FK -> User]
[Reading]
SiteKey [FK -> Sensor] ** ADDED THIS
LocationID [PK / FK -> Sensor]
SensorNo [PK / FK -> Sensor]
ReadingDtm [PK]
Basically, every table gets a SiteKey making each row unique to the site.
An alternative is this (using UUIDs in some places) : -
[User]
SiteKey [FK -> Site]
UserUUID [PK]
[Area]
SiteKey [FK -> Site]
AreaUUID [PK]
Description
UpdatedDtm
UpdatedUserUUID [FK -> User]
[AreaHistory]
Site [FK -> Site]
AreaUUID [FK -> Area]
Description
UpdatedDtm
UpdatedUserUUID [FK -> User]
AuditedDtm
[Location]
AreaUUID [FK -> Area]
LocationUUID [PK]
Description
UpdatedDtm
UpdatedUserUUID [FK -> User]
[Sensor]
LocationUUID [PK / FK -> Location]
SensorNo [PK]
UpdatedDtm
UpdatedUserUUID [FK -> User]
[Reading]
LocationUUID [PK / FK -> Sensor]
SensorNo [PK / FK -> Sensor]
