Une journée à Avignon

Je suis parti de Paris à Avignon  à 7h dans le matin en TGV. Le voyage a duré 2h:40. C’était la premiere fois que j’ai voyagé vers le Sud. Quand je suis arrivé à Avignon je suis allé visiter le Palais des Papes. Cette grande construction gothique du Moyen Age a été la residence pour 9 papes. J’ai pris trois heure pour visiter ce lieu plein d’histoire.

Personne ne dansait sur Le Pont d’Avignon, le fameux pont sur le Rhone. J’ai passé une heure lá.

J’ai visité le Musée du Petit Palais et je me suis promené dans le centre-ville jusqu’a la fin de la journée.

MVC Architecture

Model – the application data and behaviour in terms of its problem domain. It is independent of the UI. (Domain Model – POCO).

View – the HTML markup we want to display to the user.

Controller – it is responsible for handling a HTTP request. It does some things.

Router – selects the right controller. Based on some rules the router knows that a request should be handled by a method of a class (called an action) with the same name as the request. So, an action in a controller is responsable for handling a request.

ASP.NET Core Authorization

Authentication – when you ask someone who they are and you get its identity.

Authorization – decide what identity is able to do.

You can authenticate but you don’t have to authorize.

You can authorize without having any authentication.

Two main HTTP codes in web security:

401 – Unauthorized – You are not authenticated

403 – Forbidden – You are authenticated but you don’t have access

Undoing a commit in git

When forgot something on a commit:

git reset –soft HEAD^ — move to the commit one before the HEAD.

undo the last commit and move everything from that commit back into staging.

git commit –amend -m « modify something and add it to the last commit »

git reset –hard HEAD^ -undo last commit and all changes

git reset –hard HEAD^^ – undo last two commits and all changes

 

 

 

Unstaging files in git

When staging files that I didn’t mean to stage:

(use git reset HEAD (file) … to unstage)

git reset HEAD filename

HEAD – the last commit on the current branch

The file has its modifications.

Reset the file to its last commit.

git checkout — filename

Testing the usability of a website

A member of a web-design team is also a web-user and sometimes it turns out to be very hard to check the personal preferences at the door. Plus, there is also a professional perspective on what constitutes good Web design. Another level of complexity to any discussion of usability issue is given by the necessary promises made for attracting capital.

Avoid religious debate – discussion where people are expressing strongly held personal beliefs about things that can’t be proven. They rarely result in anyone involved changing his or her point of view.

Test and watch people carefully as they try to figure out what you have designed and how to use it.

A focus group is a small group of people talking about things, like their opinions about products, past experiences and reactions to new concepts. A focus group is useful for getting a sampling of users’ feelings and opinions. It is best used in the planning stages of a project. It can help you finding out whether you are building the right product.

Usability tests are about watching one user trying to do something on a website so you can detect and fix things that confuses or frustrate him.  Usability tests should be used through the entire process.

  • watch other people trying to use your site because after you have worked on a site you know too much.
  • test early in the project
  • a small number of users, not necessarily to be in the audience
  • list the three most serious usability problems you noticed
  • decide what to fix – you should always start by fixing the most serious problems first

Do-It yourself usability testing
