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. The idea is that we want to see their code and asking a candidate to program during an interview… does not go well. 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....

The always brilliant Hynek recently posted Semantic Versioning Will Not Save You . Primarily targeted at consumers of SemVer-versioned packages, it is full of insightful advice. From my perspective as an open-source maintainer, I can tell you that versioning is hard. Judging when a new release is going to break backward compatibility is not as simple as it might seem on the surface, and Hynek does a great job explaining why. Sometimes ..

Only when systematically following through the troubleshooting evidence, we get to the root cause of the problem. This session aims to help you understand (and reason about) the Oracle’s multi-process & multi-layer system behavior, preparing you for independent troubleshooting of such complex perfor..

Bitcoin (and many more) cryptocurrency prices have been sky rocketing for the lasts weeks/months, and thus their usage and mining. But have we stop thinking how this impacts the Climate Change? Before jumping into graphs, a quick recap on how cryptocurrencies work: when you buy or sell Bitcoins (for example), your transaction is being recorded into a distributed ledger. This distributed ledger is cryptographically secured against tamperin....

WFH Day 353 I didn’t sleep too bad last night. I got up at around 7:15 am, made myself a coffee, and continued to read my current book Gerta . I’m a slow reader, and if I don’t put time aside for reading, I will never finish any longer book in a finite amount of time. Reading in bed at night is something that doesn’t work for me. I usually fall asleep pretty quickly, and then my Kindle, or even worse, my iPad, falls to my face. If I start..

This post is the part of Scraping Series. Usually, when you start developing a scraper to scrape loads of records, your first step is usually to go to the page where all listings are available. You go to the page by page, fetch individual URLs, store in DB or in a file and then start parsing. Nothing wrong with it. The only issue is the wastage of resources. Say there are 100 records in a certain category. Each page has 10 records. Ideally,....
