This week was not very productive, I have try to understand and figure out how to code this application and try to make the application stateless. The application require user to verify their email address before proceeding to the period selection page. Looking at this, the first question that i asked is how to verify the email address of the user? Thanks to Dr. Shawn I have found the hash Function in the Wt library and was able to hash Read more
This week I have focused on the part of generating a certificate out of the input passed by the front end ie the email and the number of days before the certificate has expired. The post request is firstly processed to separate the number of days and email from the string using stringstream. Then the common name required for the certificate input would be extracted from the email. The other subjects required for the certificate would be set into default. Read more
The task of this week was completely different. We were asked to do some engineering design work .The client company wants to build a device that has the following: CPU + RAM SD card Wifi/GSM Camera Battery So our task was to pick up the suitable components based on the requirements given. The camera for example was requested to have a frame size of 800×600 and the ability to take 25 frame per second. The task was not easy as it Read more
Doing an internship at a small company is significantly different that doing it at a multinational firm! This is my seventh week here at AESTE and I can honestly say that the experience you will find here is like no other. Let me rewind back to the start of this week to see what I mean. Before this week, we were generally doing programming. It was fun, and challenging, and we definitely learned so many things. Then we got an Read more
This week I did not did much of the coding of the application. Instead I did much on the planning of the flow plan and the screenshots to map out the whole process of the application. Previously I did the coding without thinking about the big picture of the whole application. Now that I have mapped out the whole application, I just have to follow the flow plan of the application. What is new in the application In this application, Read more
Continuing on from the long-standing attempts at hacking the quadcopter remote communication, a few methods were used to find out exactly why the communication wouldn’t work. These methods and the resulting outcomes are discussed in this week’s post. Non-functional NRF24L01+ modules: The 10 NRF modules acquired earlier seem to be not working even with the basic communication code that was used at the start of the project. This is a huge headache as there has been no change in the Read more
Continuing the work of last week on user objects tracking, this week I started the implementation. The task for this week was to : Extract the object IDs from the user Code. Check if all IDs are unique or not. Form a list of IDs and object class name. Notify the user if any ID is repeated. As I mentioned last week , it was quite hard to come up with something unique that distinguishes each user’s declared object, so Read more
Using Http Client posting: This week I have done some Http post request to post the data input by the user to the WResource(). In this web application, the user can perform a few task. The key task is: To revoke a certificate by the push of a button. To renew a certificate by entering the period or new expiry date. To create a new certificate. for the three task listed, I decided to use the Http::Client post method to Read more
As last week was mainly focused on searching and troubleshooting problems, this week was all about applying these techniques and getting tasks done. As I discussed in the previous post, I used HTTP redirection to load the program. What I added this week, is setting cookies to handle sessions, triggering the schematic editor from other part of the page, parsing and generating JSON file to be loaded by the JointJS editor. First task was to handle multiple sessions at the Read more
As in the past week, I have been trying to advance the features of listing the certificate as well as combining it to the front end. Previously, the listing of the certificates could only list down the names of the certificate files without accessing them. Currently, my biggest concern is of accessing the approot from my WResource. It often leads on to a segmentation fault. Previously, accessing it would not be much of a problem by using the WApplication::appRoot() and Read more
