WASAText Project: specifications and Homework 1




Tuesday, 29 October 2024

Practice: Fountains

Exercise

Fontanella or Nasone

Define the API for the Fountains project (fountains are called Fontanelle or Nasoni in Rome). The Fountains project includes a mobile app that allows citizens and tourists to explore nearby drinking fountains.

In Rome, drinking water is available thanks to little public fountains, also known as “nasoni” (“large noses”, due to their nose-like shape). They were installed in the late 1800 by the local municipalities in the capital city and nearby areas. More than 2500 are still working. The “Fountains” project includes a mobile app that allows citizens and tourists to explore nearby drinking fountains (see their location and status). Also, they will be able to change the status or location of any fountains, add missing fountains, and remove those that are no longer present. A fountain’s status is “good” when it is in working condition and “faulty” if broken. The app will communicate with a central server via REST and JSON - no information is stored locally in the smartphone. No authentication is needed, nor is user identification.

Vue.js caveats

Some errors in the Vue code are somehow not shown when vite (the vue “compiler”) is used in development mode. Therefore, I suggest you to test your code with stricter settings using the following commands before committing the code to the repository:

./open-npm.sh
# (here you're inside the NPM container)
npm run build-prod
npm run preview

You may also want to open the Developer Toolbar during your tests to see the JavaScript errors and crashes and fix them before the delivery.

You can still use npm run dev when writing code. It has some valuable functions, like live reload, verbose errors, etc., that the production build doesn’t have.

(this notice was already present as FAQ #15, this is a reminder)




Wednesday 20 December 2023

Exams FAQ

We can not find the exam on Infostud to register for it. Is there another way to register?
I opened the appeals now; please try again.
We also want to know when exactly the oral exams will take place, because on 30.1 we have a different exam at 14:00.
The exams will take place the whole day. It is not possible for another exam to be scheduled on that day for the same program and the same year. In fact, they carefully avoided any overlaps, and official exam schedules were published. Should it be so, please contact the secretariat at segreteria.didattica@di.uniroma1.it
Is it possible to ensure that we can attend the oral exam on 30.1 before 14:00?
No. As I said, exams might continue till 7 pm, depending on the number of students

Lesson: HTML and CSS

  • HTML
  • CSS
  • Exercise continued from last week: finish the endpoints of the hi-lo game web app.

Note on the login in the project In the WASAphotos project, we asked for a kind of login functionality and provided instructions on how to implement it. Despite its name, we intended it as a means for you to test your web application and to demonstrate it at the exam.
So it is not a proper login and has no security capabilities. It is more of a way to create users in your system and impersonate them to test that it works properly.
For example, after creating two users, Mario and Luigi, you can impersonate Mario and follow Luigi, then impersonate Luigi and check that Mario is one of his followers.
Please refrain from implementing an entire authentication system, using well-formed tokens, or designing different APIs than the one provided for this functionality!

Clarification about grading the “last check” column.

We received several e-mails regarding a potential grading problem (missing commits, skipped students, etc.). The real issue was confusion about the meaning of the “last check” column due to incorrect labeling: the column was meant to be “the last time we checked the repository for new changes”. At the same time, we briefly published results gradually during the last weeks, which increased the chaos.

To avoid further confusion, we will publish all results at one time. Also, we changed the meaning of the “last check” column to the time when the result was published (we will change the label ASAP).

Note that we may still update individual grades (for example, if there was an error during our grading).

Call for applications for the Honors Program

ANNOUNCEMENT

Students with an average grade of 27/30 can apply for the Honors Program call, which has 8 places reserved for ACSAI students this year. In the list of topics that they just published today, you can find the topics I offer (to be developed in my GamificationLab):

  • Applicazione del machine learning alle interfacce utente per applicazioni mobili sui trasporti intelligenti
  • Car Usage and Parking Prediction for Context-Aware Interaction
  • Earthquake detection at the edge: IoT crowdsensing network
  • Implementation of the SeismoCloud2.0 Earthquake Early Warning network
  • Automatic extraction of parking availability using deep learning

The Honors Program is a beautiful experience where the student can work on challenging research problems in a real setting and in a team with Ph.D. students and master thesis students. Not only is it a very formative opportunity, but it also grants a reward of the same amount of one-year University taxes.

Please read the descriptive pages and the information to apply and submit your application by January 20, 2023.

Fontanella or Nasone

Define the API for the Fountains project (fountains are called Fontanelle or Nasoni in Rome). The Fountains project includes a mobile app that allows citizens and tourists to explore nearby drinking fountains.

In Rome, drinking water is available thanks to little public fountains, also known as “nasoni” (“large noses”, due to their nose-like shape). They were installed in the late 1800 by the local municipalities in the capital city and nearby areas. More than 2500 are still working. The “Fountains” project includes a mobile app that allows citizens and tourists to explore nearby drinking fountains (see their location and status). Also, they will be able to change the status or location of any fountains, add missing fountains in the app and remove those that are no more present. A fountain’s status is “good” when it is in working condition and “faulty” if it’s broken. The app will communicate with a central server via REST and JSON - no information is stored locally in the smartphone. No authentication is needed, nor is user identification.

Students with disabilities and SLD

Students with disabilities and SLD who have not yet done so should contact the offices or directly the SLD faculty representative Prof. Tiziana Calamoneri to submit their certifications as soon as possible.

Submitting certifications now is very important to avoid finding yourself unable to request dispensatory measures and compensatory tools at the first exam session.

Covid tracking

As indicated by the COVID-19 risk prevention and management policies, the need to track students’ attendance in the classroom remains in force. For that purpose, the programs in Informatica, Applied Computer Science and Artificial Intelligence, and Computer Science have prepared a google form that students can fill in at any time (even during the lesson or post-lesson). Attendance tracking is done to safeguard the student’s health. We, therefore, recommend you fill out this form for each class you attend.
