Shortcuts in Vim style

Some while ago I had an interesting discussion concerning the different approaches to workflow organisation and learning. It happened around at the same time, that I’ve discovered the Vimium browser extension. This coincidence lead me to write this blog-post about the workflow organisation and usage of shortcuts in everyday life. To keep the content simple, I’ll start with some general ideas on using shortcuts and then present some advantages of using their Vim-style version.

Bikes in Grenoble

Lately, I’ve taken a break from the technical publications about R and informatics in general. This is mostly because I was distracted by a more immediate problems: the choice of a bike for this academic year. My contract with the Metrovelo, the most popular bike-rental company in Grenoble, has expired around 10-th september, pushing me to reconsider my travel choices.

In Grenoble, as in many other european towns, the transportation choices are more versatile than in Moscow, or any northern cities in general. So what are the alternatives?

Gift ideas for FOSS enthusiasts

Personally I have rather mixed feeling towards the wishlists. Even though having a list of gifts is convenient, it somewhat reduces the joy. However, after some recent discussions I’ve realised that probably creating some sort of wishlist may be not such a bad idea. But making this “wishlist” useful for some other people may be an even better idea.

So, what can be interesting for people who adore gadgets and tinkering, preferring at the same time to stick with some Open Source solutions? Well, first of all I’ve looked through some suggestions and gift-lists over the Internet, but was astonished by sometimes ill chosen ideas. Mugs with UNIX memes? Tee-shirts with TUX? FOSS based symbolic and sometimes absolutely useless accessories? Evidently, it’s only my point of view, but such things are rather boring and uninteresting.

Guide des outils

Cette publication est orienté vers les étudiants qui vont suivre des cours ou faire de Projets / mener des TER avec moi cette année. Elle vise à proposer un aperçu des outils essentiels pour faciliter et simplifier le travail. Particulièrement :

Git
GitHub/GitLab/BitBucket (ici nous parlerons du GitLab hebergé par GRICAD)
LaTeX
Markdown
RMarkdown

Ce sont des outils principaux pour bien organiser son travail de la recherche et pouvoir l’accompagner par des supports numeriques.

Building a website (part 3)

In this part, we are finally approaching one of the most important and interesting topics, when creating a website: the deployment process. I do not believe that this will be the end of the sequence about the websites, because there are some more interesting topics. Among them:

RSS (Really Simple Syndication) configuration
Templates
Custom layouts
Java Script (JS) embedding
Synchronisation
Migration
And many more

But let’s leave these topics for later and focus our attention on the deployment procedure.

Building a website (part 2)

So, this post continues the sequence about building a website with R software. Today I’ll make focus on the building procedure with the help of previously chosen solution: blogdown.

Site generation with `blogdown`

The procedure of building website with blogdown may be divided into several steps:

Dependencies installation
Theme choice and file-structure generation
Building website

Installation

As it was stated before, the blogdown package uses Hugo backend to build websites. This means, that to make it work we should install both of them. Luckily, the blogdown package is able to install Hugo on its own, for this we can use the commands:

Building a website (part 1)

The idea to write this post (or rather a sequence of posts) appeared when I was attempting to deploy this website, mostly because of the difficulties I’ve encountered. So, today’s question is: how to deploy a simple static website with R?

First of all, we should start with distinguishing two main steps in website production:

Building website
Deploying the results on the web

These two topics may be rather long to explain, that’s why I’d rather prefer to separate this post into several parts.

LaTeX, publications and `tikz`

Today’s’ experience with helping to submit an article for a journal of Taylor & Francis group was educative and energy draining at the same time. Yesterday was quite a long day dedicated to styling the document, while now I had only figures to worry about. Later, I’ll definitely have to write some guide about academic writing and how R software, which can be useful in this aspect. But now lets speak about some useful tips in using tikz.

Introduction

My name is Nikita Gusarov and I’m currently doing my Doctoral studies at the University Grenoble Alpes located in France.

My work is primarily focused on exploration of the performances of Discrete Choice Models (DCM) in modelling individual behaviour. This is a rather breathtaking topic, because of its interdisciplinary nature. I have to deal at the same time with different techniques from quite distant fields, among which:

Statistics
Econometrics
Machine Learning
Combinatorics and Optimisation

As well as various behavioural theories, specific for several domains:
