AI for Everyone

You might have heard of a lot about AI, Machine learning, Data science, Deep learning, etc,... But, what exactly these terms mean and how is the connection between those. Here is my understanding:

There are two ideas of AI:
- ANI (Artificial Narrow Intelligence): E.g., smart speaker, self-driving car and web search.
- AGN (Artificial General Intelligence): do anything a human can do.

ANI is realistic and incredibly valuable. Though AGN is still too far away, and there is no need to unduly worry about it.

When talking about data in term of AI that means talking about dataset. There are several methods to get a dataset:
- Manual labeling
- Observing user behaviors
- Observing behaviors of other things such as machine
- Downloading dataset from a website or acquiring it from a partner.

Machine learning (ML) is a tool in AI. Supervised learning is a type of ML that learns A to B, or input to output mappings. Deep learning/Neural networks is a type of supervised learning which can maximize the performance of AI when dataset is big today.

Is AI a subset of data science?

No! Data science uses many tools from AI machine learning, but has some other separate tools as well that solves a very set of important problems in driving business insights.

- ML project output: a running AI system
- Data science project output: a set of insights

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: ...

Attribute 'for' of label component with id xxxx is not defined

I got the warning in the log file when I have used the tag <h:outputLabel> without attribute " for " in xhtml file. It was really polluting my server log files. The logged information actually makes sense anyway! We could find an answer as the following: "Having h:outputLabel without a "for" attribute is meaningless. If you are not attaching the label, you should be using h:outputText instead of h:outputLabel." However, these solutions are not possible just for my situation. Instead of using h:outputText for only displaying text, my team has used h:outputLabel too many places. We were nearly in our release time (next day) so it is quite risky and takes much efforts if we try to correct it. Because the style (with CSS) is already done with h:ouputLabel . The alternative by adding attribute " for " the existing h:outputLabel is not reasonable either. I really need to find another solution. Fortunately, I came across a way if I cha...

Resolution for 2016

HCM full stack developer Meetup This is the topic of HMC full stack developers' meetup this time. We have shared our ideas and discussed about them. Most of discussions is focused on career path for developers in Vietnam and what next we will do in 2016. I have a problem with my career path in Vietnam. I seem to get lost my motivation because I don't like to become either a manager or a TA (such as Technical Assistant, Technical Analysis, Technical Architect). But, why only are there either manager or TA in Vietnam? How about a 60-years experiences developer? Salary is actually an issue. I admire several great developers in the world such as Jeff Atwood ( stackoverflow.com founder), John Sonmez ( simpleprogrammer.com fouder). They created very great and valuable stuffs for the community and they are free of finance - of course, I think. Why can't I follow that way? I would like to not only create cool stuffs but also get high salary. I love to becom...

Safari (older than 14.1.1) rejects TLS connections of TURN with Let's Encrypt certificates

Summary We could not make a video call successfully on Safari older than 14.1.1. The call kept disconnecting for some seconds. We got the following error in Nginx’s log SSL: error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca:SSL alert number 48   Root cause The Safari didn’t trust our TLS certificates (certified by Let’s Encrypt) when establishing a TLS connection into our TURN server. It is a known issue that could be found at Bug 219274 - ICE does not resolve for `turns` relay candidates rooted in LetsEncrypt CA . The issue was just recently fixed (end of 2020), therefore old versions of Safari still meet the issues.   Solution In our development environment, we replaced the untrusted certificate with a trusted one. We will warn our customers about this issue in our installation guide. Technical explained WebKit is a browser engine developed by Apple and primarily used in its Safari web browser, as well as all iOS web browsers. The WebRTC of WebKit relied on ...

What the heck is Meteor DDP?

I was using Meteor for my messenger project. I was so curious about the real time connection. I wanted to know how exactly this mechanism works. In this post, I will go through the DDP Specification, an overview of WebSocket, and a simple demo about how to subscribe a publication of Rocket.Chat (containing a DDP server) from an external webpage. At a glance, I knew that Meteor invented a protocol called DDP which uses for handling real time connection. So then, what is DDP? "DDP (Distributed Data Protocol) is the stateful WebSocket protocol that Meteor uses to communicate between the client and the server." [1] All right! Why does DDP matter? "DDP is a standard way to solve the biggest problem facing client-side JavaScript developers: querying a server-side database, sending the results down to the client, and then pushing changes to the client whenever anything changes in the database" . [2] In order to understand deeply the protocol, I decided ...
