Emma scrum logs 1.4 sprint 1

2015-11-15T22:56:00.003-08:00

這個sprint 做了141點的 task

花了大概是195小時

大概是多了一個member的關係

做了比較多的事情尤其是插件

現在一個sprint可以拿到約80點的Task

還不錯
居然越來越快～

Emma scrum logs -- Sprint 4 ends

2015-10-23T01:00:00.003-07:00

幹都結束多久了才PO

XD

Sprint4的事情蠻早就做完了

前四個sprint 作了252 points
總時間為469 hrs

所以一點等於1.86 hr

而每個sprint可以做到63點

Emma scrum logs --- sprint 3 ends

2015-10-02T01:40:00.001-07:00

Sprint 3 受到人員異動及後端黑洞的影響
原本的User story沒做完
但加入1.2的插件以後
做了task 65點
花了76 hrs

所以 1點 = 1.17 hr

這是burndown

跟之前的一起算
sprint 1 = 80 hrs, 52 pts
sprint 2 = 170 hrs,70 pts
sprint 3 = 76 hrs, 65 pts
所以
velocity: 一個sprint大概就是吃62點囉
1點大概就是1.74小時

三個sprint了
這些數字應該已經有不錯的參考價值了～

為什麼要算一點等於幾個小時？

2015-09-21T18:43:00.000-07:00

因為目前的專案還不是理想的scrum專案
還是臨時會有插件
而這些插件是sprint planning meeting沒想到的事

但插件就是很緊急的事情
對客戶的Value也很高
假如我們回說
"對不起 sprint已經開始請在下一個sprint planning提出"
那有點不好啦...
但其實這樣也可以訓練PO好好排出事情跟priority
也不失為一件好事

總之
對於這些插件
假如我們真的花了比如說16小時去處理
就可以回推出這件插件是多少Task點數
sprint review的時候
才能真正反映到這個sprint的Velocity上

插件目前一個sprint大概只能吃個一兩件小的
再多也無法了

Emma Scrum Logs -- Sprint 2 ends

2015-09-20T19:38:00.000-07:00

Sprint 2 表面上做了61點

但其實不只

我們還多做了Logger跟1.2的startup time的優化

隨便抓一下 70點好了

而團隊已經感覺飽飽的了

可能無法再多做事情了

我們做了兩個sprint 分別是52, 70點
由這兩個sprint看來大約可以做到61點的Task

所以理論上
一個Sprint work hour = 250
1點大概是4個小時
實際上
第一個sprint 的52點大概是80小時
第二個sprint 的70點大概是170小時
所以 1點大概是2小時

所以抓一下
1點大概是3個小時

總之
下一個sprint以60多點的Task為目標吧

Emma Scrum Log -- Sprint 2 kicks off

2015-09-09T19:45:00.000-07:00

Sprint 2繼續做multi-device login的相關後續的User story

PBI點數是20點
另外還塞了一些bug進來

切完Task後
Task點數為 61點
所以我們要來決定
這個Sprint的work hour到底是多少
當然我們仍然可以用250小時 ( = 5人*10天*一天5小時)
但
以Sprint1的velocity來說
參考前篇
Task 52點
約做了80小時
那這個Sprint 61點
大概是98小時

到底是98還是250呢？
那就平均吧！
我就決定這個sprint的work hours 為 (98 + 250) / 2 = 174

所以
burndown chart是

先不要注意那個藍點

好的
因為我很懶
所以不想再打一篇

因為我很笨
今天是day4了
前三天的burndown chart如下

Emma Scrum Log -- Sprint 1 ends

2015-09-09T19:31:00.002-07:00

Sprint 1做了Task點數 52點

稍微換算一下
來算數學了～～

理想狀況是

以一個sprint為5人*一天專心工作5小時*10天

所以一個sprint為250小時

我們做了52點
250/52 ~= 5
所以1點約是5小時

實際情況是
因為藍色的線下降得很漂亮
day2那天的standup meeting 預計有80小時
80/52 ~= 1.6

所以1點約為1.6小時

故

Sprint1_ideal_hours_per_point = 5

Sprint1_actual_hours_per_point = 1.6

Emma Scrum Log 8/17~8/27

2015-08-27T19:24:00.000-07:00

********************************

一開始的開始，老闆們決定

1. 一個Sprint是兩個禮拜

2. 用三個sprint做完某一些事情

********************************

8/17 -- 開始寫初版的User Story (Co-work with Steven Wang)

8/20 -- 客戶端寫出所有的high level的User Story，但須SOW才能開工，於是討論這些Story與三個Sprint能做完的UserStory有哪些．

8/21 -- 玩Planning Poker，對每一個PBI做估計，使用二分法的grouping，得出所有的User Story有249點，而能在3個Sprint內能做完的只有130點．

********************************

於是老闆們決定

1. 用五個Sprint做看看

********************************

8/24 -- Sprint 1 kicks off，但因顧問到訪與team size過大，導致開了一整天的會．

會中決定：

拆成iOS與Android兩個team
拿了30點的User Story給兩個team做 “身為一個系統管理者，我希望限制一個員工只能用一支手機、一部電腦、一台平板登入 EMMA，如此才能對資訊安全有所控制”
Android的拆解Task後，Task點數為52點

8/25 -- 終於開工 (day 2)

8/26 -- day 3 開始要求QA幫忙測試refactor的android apk

8/27 -- day 4 解了兩個bug

note for setting up the build server

2014-04-09T00:51:00.001-07:00

1. make a build.xml:
my command:
android.bat update project --name ImageManager --target android-16 --path d:\SVN\bigGod_revised

2. make a build.xml for unit test projects
example:
http://blackriver.to/2012/02/android-continuous-integration-with-ant-and-jenkins-part-1/
my command:
android.bat update test-project -m ..\..\..\workspace\MemoryBox -p D:\svn\libsForMemorybox\MB_UnitTest

reference 1 (simplified Chinese)

3. modify local.properties
set the path to findbugs and android sdk on your build server.
example:
findbugs.home=/opt/findbugs-2.0.3/
sdk.dir=/opt/android-sdk-linux

4. and findbugs to build.xml
example:


<path id="findbugs-jar">
<pathelement path="${findbugs.home}/lib/findbugs-ant.jar"/>
</path>
<taskdef name="findbugs" classname="edu.umd.cs.findbugs.anttask.FindBugsTask" classpathref="findbugs-jar" />

<target name="findbugs">
<mkdir dir="reports" />
<findbugs home="${findbugs.home}" output="xml" outputFile="reports/findbugs.xml" excludeFilter="findbugs-exclude.xml">
<auxClasspath path="${android.jar}" />
<class location="${out.dir}" />
<sourcePath path="${source.dir}"/>

</findbugs>
</target>

5. modify the version-tag in the bottom-most of the build.xml



6. Indicate the path to findbugs, checkstyle and android sdk on jenkins
findbugs.home=/opt/findbugs-2.0.3/
checkstyle.home=/opt/checkstyle-5.7/
sdk.dir=/opt/android-sdk-linux

7. add a target for checkstyle in build.xml
<taskdef resource="checkstyletask.properties" classpath="${checkstyle.home}/checkstyle-5.7-all.jar"/>
<target name="checkstyle">
<mkdir dir="reports" />
<checkstyle config="${checkstyle.home}/sun_checks.xml"
failureProperty="checkstyle.failure"
failOnViolation="false"
>
<formatter type="xml" tofile="reports/checkstyle_report.xml" />
<fileset dir="src" includes="**/*.java" />
</checkstyle>

</target>

How to connect to particular SSID programmatically in android

2013-08-04T19:43:00.002-07:00

http://stackoverflow.com/questions/14119557/connect-to-the-specified-configured-network-programmatically

the key is:

mWifiMgr.disconnect();

mWifiMgr.enableNetwork(wifiConfig.networkId, true);

mWifiMgr.reconnect();

and determining if the connection to the AP is established:

ConnectivityManager connectivityManager = (ConnectivityManager)

MyController.mContext.getSystemService(Context.CONNECTIVITY_SERVICE);

if (connectivityManager != null){

networkInfo = connectivityManager.getActiveNetworkInfo();

}

if (networkInfo != null && networkInfo.isConnected()){

Log.v(TAG, "CONNECTED!! detailed state = " + networkInfo.getDetailedState());

break;

}

Log.v(TAG, "not connected!! reason = " + networkInfo.getReason());

how to collect systrace file for an android device on windows

setup android development environment on ubuntu

2013-01-31T08:40:00.001-08:00

1. download Android SDK and eclipse from http://developer.android.com/sdk/index.html#ExistingIDE

2. unzip it.

3. run eclipse

4. Go to: Window -> Preference -> Android
Make sure that SDK location is correct:

5. Click on "Android SDK Manager"

6. Select those SDK versions that you wish to have. The SDK manager will download them for you.

7. Click on "Android Virtual Device Manager", which is next to Android SDK Manager.

8. Create a AVD of your own by filling the parameters.
[NOTE]: I don't think these parameters have crucial impact on your AVD, just fill them in. But if your CPU is slow, the AVD will be laggy. If this happens, try to reduce the screen size of the AVD. Or, simply buy a new computer, like I did. :)

9. Start your AVD:

10. Create a new Android project:
New -> Android Application Project -> ... (Fill in the names there) ...

11. Then, we will have an issue here:
" adt-bundle-linux-x86_64/sdk/platform-tools/aapt: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory "
To fix that, open a terminal and type: sudo apt-get install ia32-libs
see here for more information.

12. Run your program.
