Awareness of Product Development


Software development can be understood simply as a program to receive inputs (i.e customer needs) and then produce outputs (i.e working software). It is worth it to know how many steps are in that program. When something gets stuck in a step, everyone is aware of that.

The General Process Big Picture

There are two main factors in this picture including the people with roles and their interactions. All people involved in developing the product know their responsibilities clearly and how to make things done right. Therefore, a good collaboration can be reached.

Product Roadmap Contribution

It would be great for developers to know what the next features to work on are as well as when those features will be delivered. Therefore, the product roadmap is very important.

The items in the roadmap should be contributed by ALL people involved in the product.

Because software engineers directly develop, test, delivery, and monitor the software, they should also contribute ideas to the roadmap.

How to contribute

- For small features, just create a User Story in the Product Backlog and share it with Product Owner (PO)

- For big features (knowns as Epic), create a document to describe it and discuss it with the PO.

Technical Consulting

The sales team, Product Manager, and PO work closely with customers. However, they are almost non-technical people. Therefore, technical consulting from Developers is needed.

Normally, the process of technical consulting consists of the following steps:

- Product Manager/Product Owner creates a document to describe the features' idea

- Developers describe the proposals including architectures and rough estimation. It is important that Developers are the ones who give the estimation directly. The Technical Architect plays the role of facilitating the team to have good proposals. Depending on the feature’s complexity, the research/spy user story should be created first.

For simple issues, technical consulting also can be simply conducted by direct communication without the need of creating a document.

Product Operation

Even though Developers do not operate and maintain the applications in the production environment, they should know how it is operated too. It will impact how the features are implemented as well as avoid some issues when running in production by implementing a good mechanism. Therefore, it requires some transparent information for them.

- A document describes the deployment views, infrastructure, practices, version, etc (i.e Confluence pages)

- Communication channels (i.e weekly catch-up)

Styling Sort Icons Using Font Awesome for Primefaces' Data Table

So far, Primefaces has used image sprites for displaying the sort icons. This leads to a problem if we want to make a different style for these icons; for example, I would make the icon "arrow up" more blurry at the first time the table loading because I want to highlight the icon "arrow down". I found a way that I can replace these icons with Font Awesome icons. We will use "CSS Pseudo-classes" to achieve it. The hardest thing here is that we should handle displaying icons in different cases. There is a case both "arrow up" and "arrow down" showing and other case is only one of these icons is shown. .ui-sortable-column-icon.ui-icon.ui-icon-carat-2-n-s { background-image: none; margin-left: 5px; font-size: 1.1666em; position: relative; } .ui-sortable-column-icon.ui-icon.ui-icon-carat-2-n-s:not(.ui-icon-triangle-1-s)::before { content: "\f106"; font-family: "FontAwesome"; position: ...

[Snippet] CSS - Child element overlap parent

I searched from somewhere and found that a lot of people says a basic concept for implementing this feature looks like below: HTML code: <div id="parent">  <div id="child">  </div> </div> And, CSS: #parent{   position: relative;   overflow:hidden; } #child{   position: absolute;   top: -1;   right: -1px; } However, I had a lot of grand-parents in my case and the above code didn't work. Therefore, I needed an alternative. I presumed that my app uses Boostrap and AngularJs, maybe some CSS from them affects mine. I didn't know exactly the problem, but I believed when all CSS is loaded into my browser, I could completely handle it. www.tom-collinson.com I tried to create an example to investigated this problem by Fiddle . Accidentally, I just changed: position: parent; to position: static; for one of parents -> the problem is solved. Look at my code: <div class="modal-body dn-placeholder-parent-positi...

JSF, Primefaces - Invoking Application Code Even When Validation Failed

A use case I have a form which has requirements as follow: - There are some mandatory fields. - Validation is triggered when changing value on each field. - A button "Next" is enable only when all fields are entered. It turns to disabled if any field is empty. My first approach I defined a variable "isDisableNext" at a backend bean "Controller" for dynamically disabling/enabling the "Next" button by performing event "onValueChange", but, it had a problem: <h:form id="personForm"> <p:outputLabel value="First Name" for="firstName"/> <p:inputText id="firstName" value="#{person.firstName}" required="true"> <p:ajax event="change" listener="#{controller.onValueChange}" update="nextButton"/> </p:inputText> <p:outputLabel value="Last Name" for="lastName"/> <p:i...

How to convert time between timezone in Java, Primefaces?

I use the calendar Primefaces component with timeOnly and timeZone attributes for using only hour format (HH:mm). Like this: <p:calendar id="xabsOvertimeTimeFrom" pattern="HH:mm" timeOnly="true" value="#{data.dateFrom}" timeZone="#{data.timeZone}"/> We can convert the value of #{data.dateFrom} from GMT/UTC time zone to local, conversely, from local time zone to GMT/UTC time zone. Here is my functions: package vn.nvanhuong.timezoneconverter; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.Date; import java.util.TimeZone; public class TimeZoneConverter { /** * convert a date with hour format (HH:mm) from local time zone to UTC time zone */ public static Date convertHourToUTCTimeZone(Date inputDate) throws ParseException { if(inputDate == null){ return null; } Calendar calendar = Calendar.getInstance(); calendar.setTime(inputDate); int ...

Build Dynamic Forms in AngularJS Directives

We wanted to build a dynamic form that has some types of elements such as text field, text area, label, date picker, combobox, file uploader, etc. Beside that, the form is dynamic because basing on the provided configuration data, it should render our expected GUI. We conducted a  research with two options: building our own directives or using a third-party directives. - Approach 1: using a third-party directives  + Google keyword: " build dynamic forms directives + angular third party "  + This idea met our idea: " http://blog.backand.com/build-dynamic-forms/ ", but it's not free to use.  + This 3rd-party was possible:  http://schemaform.io/ Schema form hello world app:  http://plnkr.co/edit/7Oqxxl?p=info - Approach 2: building our own directives We chose this approach because it looks more simple than using "schema form" 3rd-party and we thought that we can confidently handle it.
