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.

We’re getting ready to release a new version of the Nextcloud snap. v11.0.3snap3-rc1 is now in the candidate channel: $ sudo snap install --candidate nextcloud This update includes: An update to MySQL v5.7.18 An update to certbot v0.14.1 We’d love this new version (particularly features that involve those updates) to get some exercise before we release it. Feel like helping? We’ve put together some smoke tests to get you started.

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..

Basic function to split a string on a delimiter in LUA. Syntax is like PHP's explode - delimiter then string Returns a table of the identified substrings One known limitation is that it won't include an empty key where two delimiters occur in sequence - e.g. 'foo,,bar' - will return a table with two entries instead of 3. But I didn't need that behaviour when I wrote it, so didn't spend any extra time on it Read more…

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…

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..

Will find and identify any prime numbers between the given start and end values. Primes are identified using a factorial. Originally written as part of a solution for my May 2016 puzzle . The original solution was written in Python, this snippet is part of a (successful) attempt to rewrite that in javascript so that the solution can simply be dropped into the Developer Tools console to solve the puzzle in browser.

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.

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..
