Being too smart is your problem.

Thông minh quá cũng là vấn đề. Đây là một số biểu hiện:

1. Chán dự án
2. Không nhìn thấy tương lai
3. Anh em xung quanh thấy "ổn", trong khi mình thấy nhiều issue, rooms for improvement
4. Sếp không có tầm hình cho chính hắn, cho bạn, cho phòng/công ty
5. Công ty không thấy được giá trị của bạn
7. Không ai chỉ lối/hướng dẫn được cho mình

Vậy phải làm gì khi đó?
1. Tìm việc mới
2. Trở thành lãnh đạo
3. Làm việc 1 mình

Scrumbut: Is that good or bad

Simply but, "Scrum but" means "We are using Scrum, but <however|some reasons>...".

That means, it is meant to not to be truly Scrum.

I am sorry for using the word "Scrumbut" but I don't mean to blame or insult anyone ;)

Ken Schawaber recommends replacing the word "Scrumbut" with "Scrum And.

"Scrum And" is a path to continuous improvement.
Let's say we are at Scrum+0. Let's cirle to loop PDCA and move to Scrum+1, Scrum+2 and so on.

Examples of "Scrumbut":

"We use Scrum, but we don't do Retrospectives (for some projects) for every sprints"
"We use Scrum, but we don't have a working software after 4 sprints"
"We use Scrum, but sometimes our managers give us special tasks"

Is Scrumbut bad?
No and Yes. Scrum is an Agile toolkit and it is used as a management method. To meet our goals, adopting or transforming Agile or do what we think is needed.

Khi điện thoại bị mất, bạn chỉ cần hô "anh Q. ơi nổ banh xác cmn cho iem" là em BPhone tơi tả luôn. Về mặt security, đây là chức năng đi trước thời đại.

Ai sài thử rồi confirm nhá.

"Refactoring Doesn't Improve Code Quality"

Hoang mang quá :)

(Study finds that)

"Refactoring Doesn't Improve Code Quality":
- "here is no quality improvement after refactoring treatment to the source code"
- So, what are the impacts of source code refactoring?
- It is said the source code refactoring improves maintainability and extensibility - two aspects of quality but how about the general quality?

- Do the authors of this paper understand what is source code refactoring???

What's the difference between CIO and CTO?

Câu hỏi:
- What's the difference between CIO and CTO?
-

What they have in common:

In both jobs, a key role is helping technologists understand what the business needs and helping the business understand what the technology can do for them.
Both roles require a strong technologist with a strong grasp of business (kind of a corollary to the last point, but slightly different).
Both should be strategic thinkers.
Both should be excellent leaders.

How they are different:

I see a CTO as primarily focused on the top line while the CIO is primarily focused on the bottom line. There's some cross over, but I think this is a valid distinction.
A CTO is primarily concerned with external products and customers while a CIO is primarily concerned with running the business (internal products and customers).
In an ideal world, the CTO runs the product development organization while the CIO runs the IT organization.
If you have to choose, being a strong technologist is more important for the CTO, while being a good manager is more important for the CIO.
A CIO has to be operational and understand how to build repeatable processes, reliable systems, and the organization to run them. A CTO doesn't necessarily have to have these skill if backed up by a strong operational person in the role of CIO.

RACI and characteristics the the two roles:

Chief Information Officer

Serves as the company's top technology infrastructure manager
Runs the organization's internal IT operations
Works to streamline business processes with technology
Focuses on internal customers (users and business units)
Collaborates and manages vendors that supply infrastructure solutions
Aligns the company's IT infrastructure with business priorities
Developers strategies to increase the company's bottom line (profitability)
Has to be a skilled and organized manager to be successful

Chief Technology Officer

Serves as the company's top technology architect
Runs the organization's engineering group
Uses technology to enhance the company's product offerings
Focuses on external customers (buyers)
Collaborates and manages vendors that supply solutions to enhance the company's product(s)
Aligns the company's product architecture with business priorities
Develops strategies to increase the company's top line (revenue)
Has to be a creative and innovative technologist to be successful

What Makes a Great CTO?

Câu hỏi: What Makes a Great CTO?
Chủ đề: RACI của CTO và CIO khác nhau thế nào?

Evangelism

The CTO will serve as the company spokesperson for the product development/technology organization, demonstrating leadership in the community, with developers, partners and customers. This is often measured by establishing a university relations/recruitment program, and sponsoring or participating in at least two events per year in the developer community.

Organization

Build an excellent organization, with a strong management team committed to developing the skills of your employees. We typically measure effectiveness here by looking at development plans for all of the employees, the retention rate, and the evaluation of the managers and the overall product organization by the rest of the company.

Delivery

Make sure this organization can rapidly, reliably and repeatedly deliver quality product to market. There are several measures of delivery, including some measure of the quantity of work delivered, the consistency and frequency of release vehicles, and the quality/reliability of the delivered/launched software. Some organizations just look at reliability here, but productivity in the sense of quantity and quality is the real key.

Architecture

Make sure the company has an architecture necessary to deliver the functionality, scalability and performance it needs to in order to compete and thrive. The measures for architecture will vary based on your business, but in general we look to track and measure headroom/infrastructure work, and measure site outages due to architectural issues.

Discovery

Make sure that the architecture and senior engineering staff are participating actively, and contributing significantly, throughout product discovery. If your engineers and architects are only being used to write software then you are only getting a fraction of the value from them you should be. We suggest you track the participation of the product development/technology organization in product discovery (both duration and coverage), and the number of innovations that are credited to the engineering/architecture participant. It is also useful, although a little sensitive, to track changes to schedule post-discovery (churn), as you are always trying to reduce churn.

Systems/services monitoring (Facebook, Twitter, Amazon, Zabbix)

Tham khảo:
- Để xây dựng KPI, metrics cho phần monitorings apps
- Xây dựng dashboard
- Xây dựng hệ thống API của hệ thống
- Xây dựng hệ thống API để theo dõi hệ thống (gọi từ ngoài, làm giống Twitter, Facebook, Amazon)
- Cách theo dõi/config với RESTful, JSON based với Zabbix.

Todo:
- Có phần thương mại theo dõi app tốt, ví dụ như ca.com không?
- Hệ thống có gì cần phải theo dõi, xây dựng/thay đổi APIs của nó ra sao?
- Dùng Zabbix thì theo dõi/thỏa mãn được gì?
+ Server?
+ Network
+ Tải
+ (Web) Service (APIs)

"bạn không đau đầu về những người ra đi, bạn đau đầu về những người ở lại"

Giữ được nhân viên hay không, phần lớn do sếp (trực tiếp). Anh có đủ lý thuyết và kinh nghiệm về chuyện đó.

Hơn nữa, người ta nói: "bạn không đau đầu về những người ra đi, bạn đau đầu về những người ở lại". Nghĩa là, đi nhiều không phải là vấn đề, vấn đề là người ở lại có làm được việc không.

"Most people don't quit their jobs, they quit their managers"

sep is not in the sudoers file. This incident will be reported.

lolz. "sep is not in the sudoers file. This incident will be reported."

Who should I report this incident to?

Compare DeployGate and TestFlightApp

DeployGate:

- Japan's mixi đang dùng
- Crowd based testing
- free to try: 4 apps, 20 devices, +2 pax
- real-time testing
- Không cần SDK, device ID để test

Dùng thế nào?
- Test thử app của mình trên nhiều, nhiều thiết bị (mà bên phát triển không có)

Ghi chú thêm:
- Với apps, đặc biệt là Android based, bên phát triển không thể có đủ thời gian, công sức, tiền bạc để test trên tất cả, hoặc chí ít là nhiều thiết bị khác nhau
- Số lượng devices rất nhiều: Android 2.x, 3.x, 4.x, 5.x, iOS cũ/mới, của rất nhiều hãng khác nhau
- Người dùng thật trải nghiệm rất khác nhau
- Với dự án không có QA chuyên dụng thì nên dùng những dịch vụ test on-the-fly, crowd based

DeployGate vs. http://testflightapp.com:
- Đều dùng để test
- Nhưng mỗi dịch vụ có cách test khác nhau
- Nên phối hợp cả hai (nếu đủ kinh phí)

Giá:
https://deploygate.com/pricing
Biz plan: $120/month, 100 apps, 30000 devices, +100 pax.
