Mindset at work

Fansipan mountain

As a mentor, I always give to my new members the following practices as my advice for mindset at work.

“A over B” means while there is value in the items on the right, we value the items on the left more.

Solution over Technology

We should approach to solve the problems rather than depending on technologies. The technology limitation should not our excuse to reduce the quality of the feature.

For example, we’re strong at React, but we are willing to learn a new framework Meteor due to customer needs.

We are software engineers, we are good at problem-solving. Technologies are our toolbox.

Contribution over Complaint

When we encounter and find pain-in-the-ass issues such as lacking documentation, old frameworks/libs, lacking testing, etc.. we try our best to resolve them!

Refer to The Boy Scout Rule:

“Always leave the campground cleaner than you found it.”

Collaboration over Following

Sometimes you even need to consult customers to bring great customer value rather than always follow the provided requirements.

BIRT - Fix the size of an image

I use a dynamic image as a logo my report in pdf. At the beginning, I use table to align the logo in left or right. I meet a problem with some images with a large width or height. My customer requires that the logo should be displayed in original size. These following steps solves my problem: 1. Use Grid instead of Table 2. Set Grid "Height" is 100% and "Width" is blank 3. Set "Fit to container" for images are "true". Download the the template here .

[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...

git cherry-pick [commit]

Customer Needs My team already had a go-live app in a customer environment some months ago. We have been developing some new features for our next milestone. The situation is described in the picture below: We used Git for our codebase management. The go-live app running on our customer environment was at version ` v1 `. The latest sprint release was at version ` v7 ` for our developing app. Our customers wanted to have two separated release packages for our current sprint release. We all know that it was easy to ship the package to the developing app. However, the issue was that how we just picked some features needed for the go-live app. We called this package was a hotfix. Git Cherry-Picking Fortunately, we found that Git provided a way to achieve this task. Actually, we had all commits on the branch ` master ` already. We created a new branch called ` hotfix/v1.1 ` and we traced back which commits needed. We used cherry-picking for merging these commits to this branch....

Selenium - Override javascript functions to ignore downloading process

I have got an issue with downloading process on IE 8. This browser blocks my automatic-download functionality on my app so that I could not work with my test case any more after that. In my case, I didn't care about the file is downloaded or not, I just focus on the result after downloading process finished successfully. Therefore, I found a solution to ignore this process so that I can work normally. I use Primefaces, here is the remote command to trigger the download process <p:remoteCommand name="cmdGenerateDocument" actionListener="#{logic.onGenerateDocument}" update="xrflDocumentCreationPanel" oncomplete="clickDownloadButton();"/> The following is my test case: @Test public void shouldUpdateStep6ToWarningIfStep1IsValidAfterFinished(){ MainPage mainPage = new MainPage(); waitForLoading(mainPage.getDriver()); EmployeeDetailPage empDetailPage = new EmployeeDetailPage(); waitForLoading(empDetailPage.getDriver()); e...

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: ...
