I’m turning 30 this year, and am realizing I can no longer depend on caffeine to carry me through the day after an incomplete night’s sleep. In college, this was not a problem. Not sure if this is because of age, or increasing caffeine tolerance. Get a good night’s sleep by keeping a routine and caffeine to a minimum.

I went to a really interesting talk at Foo Cafe in Stockholm tonight. I stayed almost 2 hours over my time limit, but it was so worth it. The talk was by Martin Neumann, and he gave us an introduction to big data and some tools commonly used to wrangle it. Below are the notes I took throughot the talk. I cleaned them up a tiny bit, but mostly these are just for my personal benefit and are super messy - if you didn’t attend the talk they may..

If this is your first time visiting the blog (or you use an RSS reader), this post won’t really make a ton of sense. But the veteran Box Truck Buffs might notice that the site looks quite a bit different today. For reference, the old site: × The old layout, in all of its Bootstrap-laden goodness. May it rest in sweet responsive peace. With the truck getting a makeover , I figured it was just about time the blog ..

Eesti Vabariik – the Republic of Estonia 45,339 Km2 and a population 1.3 M people which like a ten time less than Paris or London. They have a complex and interesting history (actually most countries have an interesting history – but maybe it is a personal taste.) But what is really interesting is how Estonia use the digital to organise their society. E-residency E-voting E-school E-police E-etc. It looks quite a digital utopia…

Based on PostgreSQL 9.5.6 | Official 9.5 Documentation Context I’m scraping reports off of a inventory management system for a client. My approach is scraping and cleaning HTML tables using python, selenium, the pandas library and the beautifulsoup library. To store this data, I’m going to be using PostgreSQL. This was me getting up to speed on PostgreSQL. Installing Postgres ¶ #on mac osx $ brew install postgresql #on ubuntu (1..

I’ve been using RxSwift in some of my latest iOS projects. While I feel that it’s provided elegant UI binding and a natural feel to asynchronous programming, I have to admit that it came with numerous growing pains. I struggled to find documented solutions to some of the challenges I was facing, as RxSwift is not as widely adopted as its more affluent Java and .Net counterparts. Here are some of those hurdles that I faced, along with my s....

There may exist someone in your entourage, someone you may care deeply about, or maybe even yourself, that is being crushed by the real and raw perception of themselves. They may appear to an external observer as someone who expresses a lot of self-deprecation or negativity, but the observed categorized this as realism. We often hear the sentence "I am not a pessimist, but I am a realist," which doesn't necessarily carry the connotation we..

The standard inner product of two vectors has some nice geometric properties. Given two vectors $ x, y \in \mathbb{R}^n$, where by $ x_i$ I mean the $ i$-th coordinate of $ x$, the standard inner product (which I will interchangeably call the dot product) is defined by the formula $$\displaystyle \langle x, y \rangle = x_1 y_1 + \dots + x_n y_n$$ This formula, simple as it is, produces a lot of interesting geometry.

Requirejs Official Documentation Context Requirejs is used to asynchronously load javascript modules. I needed to use this for a game project for a client, and they wantedit in requirejs format. My javascript is weak at this point, so this was an excercise, not only in requirejs but in javascript itself. For basic usage with JQuery, you need the following files: |--scripts/ | |--main.js | |--app.js | |--lib/ | |--jquery-3.2.1.js..

We all have ideas. Sometime we don’t even realise we do, as we don’t always pay attention to the flow of our mind. Some ideas come and pass and never come back. Some stick around.

I was working earlier on a post on privacy, then realised I cannot even start to give a proper introduction to it without laying down some facts first. So, there will be no jumping straight into the subject of privacy, centralisation of the internet, and how politics is affecting the internet as a whole. Instead, we will take a couple of posts to really define the current state of the internet, also give an historical perspective, before di..

It has been a while! SnailLife work has been moving at a snail’s pace. Why? Because debugging the snail brain has turned into a highly demotivating, hellish endeavour.

The Laravel log for the original app has turned into 3 Laravel logs because I now have 3 independent apps (the front-end, Bra..

I’m an engineer, and am pretty clueless when it comes to film-making. However, I’ve been asked by a few different people how I made the ROS prototype to production on Ubuntu Core video series. While I’m not deluding myself into thinking I’m a pro, I’m happy with how they turned out, and they were made on a shoestring budget with open-source software. This post is for those who are curious about what I did, what I used, and how I did it.

They did not know it was impossible so they did it — Mark Twain Rules, somehow, always, seems to be a barrier to innovation. Status-quo is cultural protectionism The status-quo creates artificial scarcity. Because it promotes the lack of initiative It supports business as usual. The status-quo is opposed to disruption, to change, to innovation. It is opposed to improvement. It is the systemic manifestation of the resistance.
