I am gonna start writing about my experiences of learning JavaScript. Most of the topics/posts are going to be super basic but what I would like to focus is the interesting connections or point of view I learnt. And yes, thought I would categorise the series as “InitLogs” since these are the initial code/logs a lot of us will be learning and also because it will make it easy for people to look it up in case you all did find something inte....

This is a starting point blog post where different things I learn about using Python Kafka will be documented. Getting the Value out of a Consumer Record The output of a Python Kafka call is a Consumer Record which is a "set of named tuples (blah blah blah)" where what you actually want is the value tuple. This can be gotten with the .value attribute: #!/usr/bin/env python from kafka import KafkaConsumer consumer = Kafk..

Introduction I have spent a career building business applications that work with databases, starting with SQL and then moving to No-SQL. I’ve been curious how Graph databases work and how to build applications with them. It seems the sweet spot for a Graph database is when your application needs to model the interrelationships of complex and different datasets. I’ve been using No-SQL databases for these types of applications so I am supe..

As the world battles to contain the COVID-19 pandemic, every organization is seeing unprecedented changes in patterns of customer demand. Mandated and organically adopted shifts in the movement of people have dramatically changed the ecosystem of our daily lives, and in turn, what roles organizations play in this. While many businesses are facing hibernation or closure, some are thriving, with huge increases in sales, and public sector and ..

An old Cherokee told his grandson, “My son, there is a battle between two wolves inside us all. One is Evil. It is anger, jealousy, greed, resentment, inferiority, lies and ego. The other is Good. It is joy, peace, love, hope, humility, kindness, empathy and truth.” The boy thought about it and asked, “Grandfather, which wolf wins?” The old man quietly replied, “The one you feed.”

Editor's Note This article was originally written by Chris Potter and me when we worked at Reaction Commerce. It was published on April 15, 2020 on the Reaction Commerce Blog. Reaction Commerce was acquired by Mailchimp and the blog has disappeared, so I'm republishing here to keep the content available. I will need to reference it myself if I ever have to do graphql pagination again. To my knowledge, this is the most in-depth and techni....

Web scraping refers to the process of automatically extracting structured information from websites. The amount of information available online keeps increasing every day, but it is often hard to access when an API is not available to access the data programmatically. If you work in software development, it's very likely you've already been in this situation before or are in this situation right now: if that's the case this article will giv..

I agree with Kev, that readers should have the ability to view my work in whatever format they please, but I still truncate the posts in my RSS feed. Here’s why: Whenever I find a new writer , I go through everything they have ever written — turns out, good writers write good things often; this helps me find great works from their past. RSS feeds with, say, the site’s ten most recent posts make this much harder than ones with every artic..

It’s glorious to work on one task at a time, to be able to take it from start to finish completely, and then move onto the next one. Sounds great, but reality is messier than that and context switches are common. Doing so can be annoying and inefficient, but not switching means tasks and colleagues are delayed. I combine git worktrees and pyenv (and plugins) to reduce the overhead of a context switch and keep development and collabora....

Education is hard. Creating a learning process where you transfer experience to one person to an other is no trivial task. If it was, learning would be more like this But, since it is not, we will have to find other ways to go about it. Here are some interesting approaches, I have stumbled upon, which are really worth having a look at: Mike Fairclough - the badass The guy is headmaster of the West Rise School.

This blog post was originally posted on JetBrains .NET blog . Many Rider users may know that the IDE has two main processes : frontend (Java-application based on the IntelliJ platform) and backend (.NET-application based on ReSharper). Since the first release of Rider, we’ve used Mono as the backend runtime on Linux and macOS. A few years ago, we decided to migrate to .NET Core. After resolving hundreds of technical challenges, we..

One of the single worst parts of being a one man show on an engineering effort is that when you hit a serious snag, well, you're fscked . I'm at the death march phase of a project, that wonderful stage, where you're so far into it that you can see the end but it seemingly never arrives – like the speed of light, it feels like you can never quite get there. Pro Tip: At this stage being asked by your manager, on a continuous basis, "anyth....

In Part I of the article, we summarized our observations of eXtended reality’s foundational blocks - AR, VR and MR. We also discussed the popular and most relevant tools and implementations of the new technology. In Part II of the article, we will be looking at a few accessible and novel implementations of the tech.

The way we interact with technology today is not too far from what was predicted by futuristic, sci-fi pop culture. We are living in a world where sophisticated touch and gesture based interactions are collaborating with state of the art wearables, sensors, Augmented Reality (AR), Virtual Reality (VR) and Mixed Reality (MR). And, this is eXtending user experiences to be extremely immersive.

Mozilla’s mistakes — although concerning — worry me less than Google’s methodical Internet takeover. Indulge me while I bring the uninformed up to speed: after eviscerating its competitors, over half the Internet now uses Chrome. This dominance gives its creator the power to force sweeping change across this decentralized system: although superficially optional, failure to comply means longer load times, lower search ranking, and lost r....

I believe vendoring gives your application projects the most durability since the project owns every line of source code it needs to build the..

There are a lot of different password managers out there, a lot of good ones, but in one way or another, none of them quite hit the mark for me. The closest thing I found was Pass, but even that didn't quite fit the bill. It did inspire me to create my own though... Introducing SecureStore, a Pass-like password manager. Written in Bash flavoured shell and using GPG to encrypt the contents of the store. Looking at it from a high level, it's ..

Previously in database basics: 1. SELECT, INSERT, CREATE and a REPL Next in database basics: 3. indexes 4. a database/sql driver In this post, we'll extend gosql to support binary expressions and very simple filtering on SELECT results via WHERE. We'll introduce a general mechanism for interpreting an expression on a row in a table. The expression may be an identifier (where the result is the value of the cell c....
