Last week and as I mentioned in my previous blog entry I managed to compile the file that comes from the browser which contains the content of the code editor using g++ compiler ( Gnu C++compiler). In this week my task was to: – extract the syntax error and warning messages and lines numbers from the output of the compiler – Update the editor with those errors So let’s go through them one by one 🙂 extract the error and Read more
I continued working on my part in the project this week, that is, the JointJS schematic editor. First I finished some final touches on the save/load feature I did last week, then I worked on the other two tasks that i was assigned to. These were parsing the JSON file received from the the load operation, and creating a new project from within a Wresource “handlerequest()” method. To do the first task, I was asked to use the boost property tree Read more
Finally , I have received my first project ever which is to generate the back end part of our digital certificate web application. My first feature of it is the generation of digital certificate. The process of making it is rather easy as it is rather common thing on Google. However, since we would like to make the application automated for a better user experience, the automation of inputting the subject of the certificate is a rather tricky one as Read more
Finding information for revoke and renew certificate. I have checked the web and found the revoke command in this website have useful openssl commands. I have also discover the command line for renewal of certificate in this website. According to this blog, to renew a certificate, we must revoke the expired certificate 1st and renamed the request of certificate to be signed and this will renew the certificate with a different file name. But unfortunately some of these commands are not Read more
This week I have started working in my first task in the project , after spending the last couple of weeks studying and digging here and there … the real work has just begun 😀 .. Last week and as I mentioned in my previous blog entry I managed to integrate the code editor (codemirror) with witty. So my first task was to both save the content of the editor to the server and to load some code from the Read more
In this week I was officially assigned tasks to do in the project. I was assigned 3 tasks all related to JointJS and Wt Wresources. However, I could only manage to finish one task which was handling saving and loading a Json file to and from the server. The first part of the task was loading the file from the server to the client browser. This was a fairly simple task. To do that, I created a Witty function in Read more
We are currently trying to develop a simple web application to generate, revoke and renew self-signed certificate.The challenge i have been assign is to design a better user experience to smoothen the process of certificates. The figure bellow shows the rough sketch of the user experience when processing certificates. first, user will have to log in to the web application with a valid user name and password. THen user will be able to log in to the main page which Read more
Following last week’s information on the communication data coming from the Quadcopter remote, the next logical step was to replicate it so that the Arduino can be used to communicate the quadcopter instead. Some interesting findings led to a better understanding of the communication between this particular Remote Control and the quadcopter and also a stack of code was developed to try and replicate this communication. Understanding the Payload: Once it was obvious that the Power-up/initialization sequence can be ignored Read more
In this week I continued reading and studying witty. So after covering the Graphical User Interface (GUI) part of witty last week I started directly exploring its non-GUI part.When we deal with non-GUI part we need to be familiarized with some terms such as “resource”. A resource is any document or file other than the main page (the html page) that can be rendered to the users. Witty provides a class named “WRESOURCE” which can be used to create resources Read more
THe progress of learning Witty this week is very slow, i merely scratch the surface of the entire Witty framework. What i did in this week was mainly exploring the widget in Witty and the concept of http request and response. I did not go through every single widget in detail. I spend most of my time figuring out the WResource code. It is a target for the HTTP request and it allow us to upload file to the server Read more
