I am a staff engineer at Canonical, where I have worked for six years. My time here has been filled with brilliant people and amazing technology, and I’ve had the pleasure and privilege of playing pivotal roles getting a number of new projects off the ground. As I’ve said in the past, I joined Canonical to help my technical growth, and they delivered in spades. I have really loved my time here, which made the decision to leave all the more ..

With the advent of smartphones, social media platforms are on the rise. Let's step back and try to understand what social media are, not by citing events and instances happening on the different platforms, nor the countless consequences but by describing the characteristics of this new informational channel. We'll go over the rest later but let's take some distance for now.

So you’re trying to use the Terraform azurerm_function_app_host_keys resource to get the keys from an Azure function after deployment. Sadly, as of 03/2021, this can fail intermittently 😢 (See issue 1 and 2 ).+ [Edit: Hopefully this issue is resolved by this PR once released so worth reviewing once the change is released] These errors can look something like these below: Error making Read request on AzureRM Function App Hostke..

I am an application/backend developer who has to quibble with databases more often than desired. I can get my way around Postgres pretty well, but I can always use a hint or two, especially when it comes to fine-tuning and performance. I stumbled upon Cleaning Up Your Postgres Databases . It offers useful advice on spotting performance bottlenecks in your Postgres database. Take the cache and index hit queries, for example. The first..

There are dozens of different ways to estimate quantiles. One of these ways is to use the Sfakianakis-Verginis quantile estimator. To be more specific, it’s a family of three estimators. If we want to estimate the $p^\textrm{th}$ quantile of sample $X$, we can use one of the following equations: $$ \begin{split} \operatorname{SV1}_p =& \frac{B_0}{2} \big( X_{(1)}+X_{(2)}-X_{(3)} \big) + \sum_{i=1}^{n} \frac{B_i+B_{i-1}}{2} X_{(i)} + \frac{....

You can learn quite a bit about a browser from observing the requests it makes in its first moments with a new user profile. Often, a cursory examination will tell you a great deal about how the browser thinks about, and handles, user privacy and security.

I’ve created a few quick-reference articles and it might not be clear why. There are a few reasons: These articles are mainly a reference for me. I find myself searching the same things over and over, looking for the purple link, scrolling through the article, then copy & pasting code. I’d rather not go through the hassle. These articles aim to solve that problem. I aim to keep the answers above the fold . I don’t want to have to scroll ....

Often it is useful to save python data to json files. The following code will demonstrate how that can be done. “God bless JSON!” ~ a soon to be famous programmer import json data = {'a': 1, 'b':'hello', 'c':False} filename = 'awesome_data.json' # write data to file with open(filename, 'w') as f: json.dump(data, f) # read json from file with open(filename, 'r') as f: data = json.load(f) print(data) # prints {'a': 1, 'b':'hello', 'c..

Autoencoding stock prices as found in Heaton et al., 2016 So you want to build an autoencoder? Great! This article will demonstrate how to build an autoencoder and use it to measure stock prices against an index. This technique is described in more technical terms here . Once we’ve trained the autoencoder, we can use it to measure how well each component follows the other members of the index. This can be useful for finding deeper in..

tldr; reimplement standard library functions in your favorite language without loops . Background For a few years after college I spent a lot of free time doing projects in Standard ML and Scheme. As a result I got really comfortable doing recursion. The two big reasons for this are 1) neither Standard ML or Scheme have loops and 2) they both have very small standard libraries. (Ok, they have loops. They're just so limited as to be useles....

As any other bookworm worth its salt, I digested a generous amount of books on books and the history of libraries. Alberto Manguel’s The Library at Night was last, and that is a pity. It probably arrived just a little too late on my shelves. I wish I found it at the beginning of my reading journey when my enthusiasm for libraries and their contents was pristine. Manguel’s writing is mesmerizing and capable. The lover of libraries and thei..

Our journey begins with three terms, propaganda, influence, and persuasion. To most, they sound like synonyms but each convey a different concept. Like any form of communication the internet can be used as a channel for them. What does communication consist of? The very broad domain of communication studies — with multiple sub-disciplines such as journalism, film critic, public relation, and political science — often use a simple reductioni..

Following a phone screen, we typically ask candidates to complete some coding tasks.

I had a candidate some years ago that was provided with a machine, IDE and internet connection and walked out after failing for 30 minutes to reverse a string. Given that his CV said that he has 8 years of experience, I consider myself very lu....
