LogiCola helps you learn logic. This is a web version of the original software built by the late Professor Harry Gensler.

Only you know who you can set out to be — Never let anyone tell you otherwise.

My name is Malik, I was born in Lisbon and moved to Berlin where I work in product enablement (what the industry calls Product Manager). In my free time, you can find me building apps, events and communities that foster connection, enable education and create more access to opportunities.

Right Now, I'm:

• ✨ Writing my dissertation on the application and impact of reciprocation in human-computer interaction.
• 🍁 Building Outono.org, a way to find and have coffee with Portuguese people working in tech, anywhere in the world.
• 🌱 Building and maintaining Logicola, an e-learning platform, originally created by the late Harry Gensler, so more students can learn formal logic and improve their reasoning.

✨ Looking to learn with more seasoned technical PMs and to collaborate in projects that touch computer networks, distributed systems, blockchain and decentralisation. I want to build something that makes the web better and improves the infrustructure of the internet. If you're stumbling upon my profile and feel like grabbing a digital coffee would be energising, please reach out:

logicola's Issues

2 identical answers

Set C Propositional Logic
Question 4/10 – it has 2 identical correct answers to question, one normal and one is the same but with one extra pair of parentheses outside of propositional expressio. they look like "~ ... V N" and "(~ ... V N)". Here ellipsis is for Propositional variable whose name I don't remember.

Create documentation to enable collaboration

Right now it's hard for anyone to contribute because there is no documentation on how to do so. I should create rules and update the README with helpful guidelines and resources.

Cannot select more than one answer in Quiz

Few quiz questions require more than one selected answer, it impossible to select more than one at least using my mobile Chrome browser, but probably this is same with any device and any browser.
2) It will be good to warn the user in cases when he is allowed to select mire than one answer and when he can only choose 1 answer.

Mistype of word in very first question of the very first test

in Set Q "Meanings and ..." Question 1/10 - mistype in the text of question: the word "vacuities" it is written as vacuLties.

Quiz Mode: Questions with multiple correct answers are not displaying the result correctly.

When a user checks the answer for questions with multiple correct answers, all of them are displayed as incorrect:

The frontpage is a bit misleading

I stumbled across this from hackernews.

I think a big problem now is that the frontpage looks like you need to sign up, or that it's a newletter signup page. It spends a third of the page on the update newsletter signup and the real content is hidden behind a tiny "chapters" menu in the top.

Imo the front page should be two big buttons for the two chapters so you can click through and start directly.

Problem with two correct answers.

        id: '6.41',
        prompt: 'If D then M, and L',
        options: [
          { id: 0, label: '$ D \\rightarrow M \\cdot L $' },
          { id: 1, label: '$ (D \\rightarrow M) \\cdot L $' },
          { id: 2, label: '$ (D \\rightarrow (M \\cdot L)) $' },
          { id: 3, label: '$ ((D \\rightarrow M) \\cdot L) $' },
        ],
        correctId: [3],
        answer: '',

Answers 1 and 3 (2 and 4 in screenshot) are equivalent. Wrapping the statement with an additional parentheses doesn't affect the logical semantics.
