Some resources about PMI-ACP certification

Found this list in an old email. This was how I prepared and passed PMI-ACP three years ago. So can't grantee all of these are still available now. Feel free to comment if you found issue or have new resources to add!

# the book 
This is the book I mentioned about PMI-ACP test, $69. It also on Amazon, but at higher price ($99).

along with the book, this website also provide a combo, with some tests. I didn't try them, so don't know whether they're good or not.

# online course 
I also bought this online course, to get 21 PDUs, which is a must-have for the test. I bought 90 days access ($179.99), but actually 30 days($99) is already enough if you have enough time in those 30 days. They have same things, just different access time. The course comes with some video training (from those you'll get 21PDUs), and 3 free tests, which has bad design and some answers are even wrong.

# A very good study guide. it's FREE. MUST-HAVE.

# A wiki for Agile. This is a good reference for the test and daily work.

# Also online exams. I didn't buy this. But seems their free exams is better than Simplilearn.

# Mike Cohn's book Agile Estimating and Planning. This will let you understand most knowledge of the test.

Show Volume icon in Windows 10

This may seem silly, but it did take me about 5 minutes researching online and play with new control panels in Windows 10. And Here's my steps to show Volume icon in task bar. Hope this post will save some time for others.

3. Click "Turn system icons on or off"
   
   
   
4. Turn "Volume" option on

For example, below snapshot finds all numbers followed by minus, and move the minus to left side.

Code 10: Suspicious Situations (with Discover)

If you are suspicious of the validity of a Card or the presenter of the Card for any reason, you should notify the Authorization Center at 1-800-347-1111 using the Code 10 Authorization procedures described below. Code 10 Authorization procedures apply only to Card Present transactions, but can be used regardless of the dollar amount of the Card Sale or Cash Advance, or your assigned Floor Limit.

• Call the Authorization Center and ask for a Code 10 Authorization. This will automatically direct you to the security area of the Issuer
• Security personnel will ask a brief series of “Yes” or “No” questions about the Card or the presenter, and may ask your employee to request confirming identification from the Card presenter
• If the Issuer’s security representative is able to confirm the identity of the presenter as a valid Cardholder or authorized user of the Card, a positive Authorization Response for the Card Sale or Cash Advance will be given and the Card presenter will not be aware that anything unusual has transpired
• Some Issuers may request that you retain a Card. If your employee is instructed to retain the Card, your employee should do so, but only if permitted by your policies and only by peaceful and reasonable means (see Section 11.2)

How to sync outlook to Google Calendar

Updated at 1/22/2016:

Since Google Calendar Sync isn't working for a long time. I've found this tool (gSyncit) is quite simple and useful. A small amount of money saved me lots of time. I'm only using it to sync all events from Outlook to my Google Calendar. But actually you can do a lot of more on it.

How to enter CentOS Text Mode

To Text Mode: Ctl + Alt + F1/F6

To Windows Mode: Ctl + Alt + F7

当在系统启动时直接进入字符工作方式后，系统提供了多个（默认为6个）虚拟控制台。每个虚拟控制台可以独立使用，互不影响。可以使用Alt+F1～Alt+F6进行多个虚拟控制台之间的切换。如果用户使用startx命令在字符CentOS界面下启动了图形环境，那么可以使用C trl+Alt+F1～C trl+Alt+F6切换字符虚拟终端，使用C trl+Alt+F7切换到图形界面。

开源数据库 Sharding 技术 (Share Nothing)

转载自 http://www.dbanotes.net/database/database_sharding.html

从 Shard 到 Sharding

"Shard" 这个词英文的意思是"碎片"，而作为数据库相关的技术用语，似乎最早见于大型多人在线角色扮演游戏(MMORPG)中。"Sharding" 姑且称之为"分片"。

Sharding 不是一门新技术，而是一个相对简朴的软件理念。如您所知，MySQL 5 之后才有了数据表分区功能，那么在此之前，很多 MySQL 的潜在用户都对 MySQL 的扩展性有所顾虑，而是否具备分区功能就成了衡量一个数据库可扩展性与否的一个关键指标(当然不是唯一指标)。数据库扩展性是一个永恒的话题，MySQL 的推广者经常会被问到：如在单一数据库上处理应用数据捉襟见肘而需要进行分区化之类的处理，是如何办到的呢? 答案是：Sharding。

Sharding 不是一个某个特定数据库软件附属的功能，而是在具体技术细节之上的抽象处理，是水平扩展(Scale Out，亦或横向扩展、向外扩展)的解决方案，其主要目的是为突破单节点数据库服务器的 I/O 能力限制，解决数据库扩展性问题。

Amazon Architecture

This is a wonderfully informative Amazon update based on Joachim Rohde's discovery of an interview with Amazon's CTO. You'll learn about how Amazon organizes their teams around services, the CAP theorem of building scalable systems, how they deploy software, and a lot more. Many new additions from the ACM Queue article have also been included.

Amazon grew from a tiny online bookstore to one of the largest stores on earth. They did it while pioneering new and interesting ways to rate, review, and recommend products. Greg Linden shared is version of Amazon's birth pangs in a series of blog articles
