Fortunately Oracle has a nice icon for JDeveloper in its official twitter account. It looks much better, isn't it? :)

Well, I thought everything was done and I can continue my work with JDeveloper. Then I found the icon in sidebar is not correct. It use the icon of Java. Shit.

Thanks to Google, I found the solution for this is to set StartupWMClass in the desktop file to tell unity it is a different application from other java applications. StartupWMClass can be found through command xprop|grep WM_CLASS. For JDevloper, it is oracle-ide-osgi-boot-JDeveloper. In a word, you can solve the problem by attaching the following line to your desktop file.

StartupWMClass=oracle-ide-osgi-boot-JDeveloper

That's all. And that's how programers waste their lives. :)

• Sublime Package Control The first package you should install. It is a package manager which allows you install/remove packages.

• Theme - Soda Popular theme. It can be install though package control.

• alternative_autocompletion Textmate like autocompletion. t can be install though package control.

• SublimeRope Python autocompletion. t can be install though package control.

• SublimePythonTidy Python code formatter. Installing it though package control doesn't work. Read the instrution in here to install it manually.

I found that there are some RDP clients on linux which support NLA here . If you do really need this feature, you can give it a try.

• Setup repo command by following the instructions in this page.
• Execute

 repo init -u https://android.googlesource.com/platform/manifest 

• Go into .repo folder and open manifest.xml. You will find all information of all sub projects.
• Download the subprojects using

 repo sync project0 project1 project2 

You can also download the sub projects using git clone if you like.

In Mercurial, a branch is embedded in a commit; a commit done in the ‘do-test’ branch will always remain in such a branch. This means you cannot delete, or rename branches, because you would be changing the history of the commits on those branches. You can ‘close’ branches though. As Jakub points out, these “named branches” can be better thought as “commit labels”.

背景：

1. 客户的老系统已经用了几十年了。于是客户IT部门花很多钱（上千万）在内部开发了一个新系统（以下简称新系统）。这个系统的想法不错，希望通过管理客户的人际关系网络，来分析出客户的风险。但开发并不成功，开发两年只实现了有限的功能，性能很差。客户的大领导转向我们公司的产品。

2. 我们的产品在行业中有几个比较成功的客户。有行业领域的经验积累。但产品本身并不算很成熟。销售展示的时候有夸大成分。行业本身比较复杂，各种客户确实有复杂的定制需求。

• 钉子： 客户IT部门强烈要求在产品中定制他们新系统中的一些功能。
• 锤子1 -- 架构师： 本来公司没有准备架构师（因为是现成的产品，架构师也不可能改变产品的架构），但客户要求有，于是临时从外面顾问公司请了一个，对公司产品不了解，但本身经验很丰富。对于钉子，架构师的考虑是需求比较合理，技术难度不大（基本没什么技术难度）。更重要的是，客户乐于付钱去在我们产品上做这些定制。于是很积极的在和客户讨论相关的细节。 //注释：增加新功能对于架构师/程序员更有满足感，尤其是对产品不熟悉，在业务方面会很有挫折感。
• 锤子2 -- 产品专家 产品专家对产品和行业都比较熟悉。对于钉子，专家强烈反对客户对定制我们产品的要求。专家的考虑是： 1. 这个并不是客户的真正需求，只是客户的IT部门一厢情愿的想法。在他做产品实施的这么多年，没有接触到过类似的需求。他需要接触真正在使用系统的客户来作出判断。 2. 这个并不是一个很关键的功能。 3. 根据他的经验，客户对于产品的定制，大部分都是失败的。并且对于公司来说，对产品的定制程度越高，对产品支持的成本就越高，升级产品的难度就越大。毕竟，公司是卖产品而不是卖服务的。 4. 还没到最后时候，没必要答应客户去做这样的定制。

最后：我就是个打酱油的，打酱油的心态很重要。

That's it. This is so exciting that I can get rid of the OWA access.
