Building an iOS project with Hudson

I'm mostly writing this here for archival purposes. This is how I used to build iOS projects via Hudson (I don't have any iOS projects ongoing).

First, since Hudson runs on a Linux machine, I need to add a new node then start the agent on an OSX machine from an account where I have all the digital keys set up properly.

Next, supposing I have an iOS app called Example,I just tell Hudson to poll the SCM then execute the script:

TIME=`date "+%Y-%m-%d_%H-%M-%S"`;


rm -r build || true;


xcodebuild -target Example -configuration Distribution -sdk iphoneos3.1.2 clean build


  && 


  (mkdir build/Distribution-iphoneos/Payload; mv build/Distribution-iphoneos/Example.app build/Distribution-iphoneos/Payload)

  && 

  (cd build/Distribution-iphoneos && zip -9 "example-$TIME.ipa" -r Payload)

Afterwards Hudson just needs to "Archive the artifacts" from build/Distribution-iphoneos/*.ipa


Obviously you need to tweak the sdk version a bit as this script…

NetBeans Slowness detector with Growl

Got surprised today when I saw the slowness notification on Growl:


I rarely get this message but it's nice to see it published via Growl, using my OSX Notifications module which is a Growl bridge for NetBeans Platform notifications.
Clicking on the notification


gets you this:



I'm not entirely satisfied with the way this message is presented because I would need a "Close" button, not an "OK" button. Also -- clicking on that hyperlink seems to open a new window behind this dialog.
Anyhow, there isn't much I can control since we have a lot of native components due to the broken OpenIDE AWT NotificationDisplayer API which encourages custom JComponents.
This particular notification for example should use no custom component. It should just say: "Slowness detected: Not responsive for 5 s" and then clicking on the (Growl) notification should open the "Report Problem" dialog.

NetBeans Growl notifications

Demo time



This plugin provides Growl integration with NetBeans. If you are using NetBeans on OSX and you have Growl, download my plugin.

As a proof of concept builds are shown but all other notifications that usually would have appeared using the default implementation are now posted via Growl.

Complex UIs trigger just a simple notification and then display a dialog when clicked with the actual custom components (obviously one can't publish custom Swing components in a Growl popup).



Speaking of complex UIs, some custom components are just JLabels that simulate hyperlinks so I would say those might be migrated to a normal text and ActionListener.

Background

One thing that NetBeans needs is OS-aware notifications and my two focused OSes are Ubuntu and OSX.

On Linux we have the Desktop Notifications Specification, which is a very clean, D-BUS based specification for desktop-wide notifications.

Ubuntu extends and modified the specification a bit as well as define a quite nice design gu…

MySQL as the first NoSQL database

I was watching yesterday a presentation at GeekMeet Timisoara about how to scale your websites and all the MySQL-related advices were as expected, but upon thinking about it, entirely agains normal database mantras:

You should de-normalize the database (copies are easier to access and cheap)You should disable transactions (ie. use a MySQL storage engine that isn't transactional).MySQL Master-Slave replication (which is asynchronous!)
This made me realize that MySQL is successful precisely because of all the things I discredited it for.

You see, in my book MySQL was never a real database because, initially, it wasn't transactional. For the project where I could choose the database, I picked PostgreSQL and I always used MySQL knowing in the back of my head that, in fact, it was a bit of a sham.

But this might just be MySQL's good fortune: by providing a simple storage engine with some SQL front-end, they proved that most people don't need ACID compliance.

Furthermore, as …
