A Summary of my PhD

Acronyms

When specializing in a field, it is common to use and come across acronyms. In some cases, acronyms break the perimeter of the field and start being used by people at large. It is handy to say DNA rather than Deoxyribonucleic acid, so it is no wonder why many acronyms populate our everyday language. In many cases, however, acronyms are a small barrier for people becoming familiar with a field.

Et Multikulturelt Samfunn

Oslo er en multikulturell by. Det bor mennesker fra mange nasjoner her. Hvilke fordeler og ulemper synes du et multikulturelt samfunn har? Det er mange fordeler med å ha mennesker fra mange nasjoner som bor på samme sted. For det første, tar de med seg mat og forskjelle kulinariske tradisjoner. De åpner restauranter i Oslo og både nordmenn og de andre utlendingene kan spise og teste nye typer av mat. Dessuten har et multikulturelt samfunn personer som ikke tenker på den samme måten.

Debts

Summary: Every time we rip the benefit of something without knowing what’s behind we are contracting a debt. Eating a delicious meal without knowing how (or willing to) to prepare it is a culinary debt. Most of us are comfortable with the idea and indeed repaying the debt with money is what makes the busness of restaurants to keep going. However, there a several kinds of debts, in virtually everything you can think of.

Escaping the local optimum of low expectation

Takeways

L.F. gives five advices during the video, which I think are worth reflecting 1. 2.

Consciousness

Summary. We are our greatest mystery to ouselfs I am often surprised how people are eager to start long debates about consciousness and its implications, if animals are conscious, when the fetus becomes conscious etc. without stopping first and ponder a definition: what is consciousness? As often happens, there are several definitions in the wild and a safe bet is that no one sitting around the table has the same one.

My way to read a book

Reading seems easy. Your eyes might run effortlessly, crunching black ink shapes on snow white paper and yet, when you try to recall what you have just read, emptiness. It happens to everybody, that’s why I believe it is important to have some sort of technique while reading. Even if is seems as simple as reading. Those are the steps: Gather contextual information about the book. Who is the author? When and where was it written?

Mining in Bitcoin

Summary. The gold of the 21st century is not made of atoms but bits. Old terms acquire new meanings, while society steadily walks towards post-modernism. The term mining might evoke ancient times images: gold diggers of the 19th centuries rushing to be the first one to discover a gold vein, or in more recent times it might remind you of the pixellated word of Minecraft (and dozens similar). In Bitcoin, mining is not performed by digging a hole with a shovel but instead by computing cryptographic hash functions as quickly as possible in order to find our gold: the solution to a crypto puzzle.

MiCa: A Compositional Architecture for Gossip Protocols

The paper can be found here. and discusses a system to build management tools based on gossip protocols. In general, gossip protocols are characterized by randomized peer selection and periodic communication, which makes them extremely fault tolerant since there is no realiance on a single path. MiCa allows to compose several different gossip protocols and to run them independently A protocols is defined by a tuple containing: Node’s states Rate of gossiping View: A probability mass distribution to sample the peers update of state The framework supports different typs of composition

The benefit of programming

This is a small story about having a “programming hat” in your closet ready to be worn. I like math and I have great respect for every profession that involves it. Therefore I continuously try to keep me in exercise solving problems and recently I have found out about a beautiful website called Brilliant. It has a very well design that makes you wanting to spend hours there and proposes loads of exercises.
