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
Well this week was not really fruitful, it was more into doing research and understanding what should be done next.So before talking about what happened let me start first by briefing you of what has been accomplished so far. Codemirror integration with Witty Saving and Loading the user code file Checking the user code for syntax errors updating the user with those errors and warning. You can refer to my previous blogs entries for more information about these topics. 🙂 Read more
Understanding Internal path To make the web application of the certificate process navigate and redirect between pages and application within the whole web page, I referred to one of the project that have been done by Shawn and discover a new structure of the application. Previously I have applied the basic yet tedious way to connect and link between application and application to the server using the feature addEntryPoint() of the WServer. By this method, redirect and hard code the Read more
The progress this week was relatively slow. We have been facing some problems with the implementation of the tasks. Though, the problems at first seem minute and trivial, yet, when it comes to real implementation, complexity builds up! Before starting on this week tasks, we were first required to improve our previous code. These improvements included error checking (paranoid error checking), properly structuring the code in form of functions, and adding documentation to our classes and functions. After that, we Read more
Well, there is a first time for everything. In my many years of dabbling with Linux, this is the first time I had experience a 1-minute kernel build. I achieved it by using a compilation cluster using distcc. As the image shows, nearly the entire kernel compilation was distributed over a number of machines. As a result, the kernel compiled successfully in about 1-minute as measured using the wall clock. Furthermore, the compilation cluster was not made up of super Read more
