BarcampSaigon 2015


Barcamp Saigon is one of my most expected events of the year. This year, it took place at RMIT university. As usual, it brought many useful topics to the community. Here is all topics that I have attended.

Scale it! - Lars Jankowfsky

Lars is founder of 8bitrockr.com

How do we make a decision correctly? It is hard to know that until we try and measure it. He gave an example about how good an app was. And, most of people thought that the app with nice user interfaces is good at the first look. But it is not correct because it is only true until we try to use it, even the nice GUI app sometime is not good at UX, functionalities, etc.

The key of success for working in team is collaboration. We can not only base on the experience of members likes: "In my opinions| As I know.... this is the best way..bla..bla.." but we should test it. Therefore, manually testing as well as automation testing is more and more necessary nowadays.

"Don't think, just try" - he said.

Shelfout - Chia sẻ sách và đam mê đọc sách - Nguyễn Trọng Tín.

Nguyễn Trọng Tín is founder of shelfout.com. His idea is about creating a community in order to sharing books. He saw that 81% of book is not used again after it is already read once and he called it is waste. He has already found some existing systems like goodreads.com, Facebook groups but they are not satisfied his expectations. By shelfout.com, he wants to connect all people with passion on reading and books can be used more effectively.

Learn or Die? - Lars Jankowfsky.

Once again, he gave a question "If I want to build an app, which programming language should I use?". Actually, we are not sure. He provided some information from surveys and statistic that shows a lot of languages can be used and the popular one is different from region. So, we should be flexible base on what we know. The world always changes and we should learn to update our knowledge.

IoT How developers can get money - Thanh VNG.

Thanh is working in VNG, Vietnam. IoT (Internet of Things) is a bit trend today. Therefore, developers can have a big chances to work and earn money from that.

Why your proposal was ignored? - Soshi  Nemoto.

Soshi is from Molodo Vietnam. Your proposal should be logical.

About Barcamp Saigon:
"BarcampSaigon is an unconference that was created in the tech community in 2005. Organizers of the event only organized the space and the people from the community were the presenters"

Gzip upload on browsers

Today, I faced a problem that I could not upload my archive file with gzip format on Firefox, even it worked on Chrome. I was using macOS. My application had a setting to whitelist accepted files. I’ve already added "application/gzip" to that list. "It’s strange!", I thought. I finally figured out that my uploaded file's type actually was "application/x-gzip" on Firefox. I also asked my colleagues to check their uploaded files on Window and Ubuntu. Hmm… they were totally different! It was "application/x-compressed" on Window, and was "application/x-compressed-tar" on Ubuntu. In fact, gzip is already standardized by IANA. There is a note in RFC-6713 as below: "Some applications have informally used media types such as application/gzip-compressed, application/gzipped, application/x-gunzip, application/x-gzip, application/x-gzip-compressed, and gzip/document to describe data compressed with gzip. The media types defin...

DevOps Toolchain Enhancement

 Historically, our company ubitec had started with a customer project. Agile/Scrum was our proposal for working with customers. Time by time, Agile/Scrum also became our culture for software development. To be successful with this development approach, we somehow needed to have a fast release for customers (i.e. every one week). Back then, we had a build tool Jenkins which was responsible for having sprint release packages for our customers. The build job pipelines contain some steps such as gathering the artifacts, checking the code convention, running the tests, building docker images, and packaging an archived file (a zip file). The set of tools involved in a pipeline is roughly called a toolchain. It is just a part of a bigger process called the DevOps toolchain. Source: https://www.ibm.com/blogs/cloud-archive/2016/11/devops-architecture-available-on-bluemix-garage-method-site/ DevOps is a proven method that fits Agile. Today,  it is even treated as a mandatory factor...

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 .

Automating deployment and managing apps on OpenShift

Previously, we maintained OpenShift templates for deploying apps in development environments as well as delivering these templates to our customers for their on-prem deployment. Customers who refer to our templates (as well as documentation) have their own configuration management tools to automate the deployment such as ArgoCD and FluxCD. My son's buildings Our developers usually modify templates (YAML) directly on OpenShift for testing and then adjust the corresponding templates stored in the Git repository in Bitbucket. This sometimes causes an issue that delivered templates are incorrect because: - Developers forget to update the templates in Git repositories. - Developers don’t test the templates Therefore, our goal was to integrate a tool into our CI/CD that can automate and manage the configuration of OpenShift apps. The delivered templates should be the ones that are able to run on our OpenShift with the following purposes: - Automate deployment from templated in Git repos...

My must-have apps for daily work

There is no doubt that cool apps can help us be more productive and enjoyable at work. For the time being, I really love the following apps which are used by me almost every day. 1. A personal Kanban In fact, a personal kanban is the most useful app for me. Why does it matter? It is not just a to-do list, but it keeps me motivated every day because it helps me be able to know what my "big picture" is. I usually set up my plans together with a path to reach them.  KanbanFlow  is my preferred tool. KanbanFlow 2. A terminal Needless to say, a terminal is a must-have app for every developer, especially the ones use macOS/Linux. Due to its importance, I love to decorate and enhance it to be super exciting with various tools such as  iTerm ,  oh-my- zsh , and  thefuck . ;) iTerm + oh-my-zsh 3. A documentation "ecosystem" As a developer, I can not remember all things that I have experimented a day. Moreover, a document is really useful for sharing an...
