Somehow I got curious: what would be the smallest bitmap font that would still be readable? why 2x3 grid There are plenty of existing retro 8x16 bitmap fonts, like the ones used in VGA graphics and text-mode consoles. We should probably be able to go much smaller than that. We only need to encode 26 different symbols. If our encoding is perfect - we need roughly 5 bits of information, or 5 pixels, each being either black or white.

I recently had an interesting experience with Python dictionaries that made question one of Python's foundational principles i.e. TOOWTDI: There should be one– and preferably only one –obvious way to do it. Although that way may not be obvious at first unless you're Dutch. More… The application was a large scale JSON processor and, in Python, JSONs are mapped to Python dictionaries which correspond to Ruby hashes. The issue is ....

I recently had the odd situation where it seemed like I had outbound Internet connectivity issues under Ruby powered by Docker but not with Python powered by Docker. Here's how I disproved this: docker run -it ruby:2.7.1 ping google.com 64 bytes from ord30s26-in-f238.1e100.net (216.58.192.238): icmp_seq=1 ttl=37 time=15.2 ms 64 bytes from ord30s26-in-f238.1e100.net (216.58.192.238): icmp_seq=2 ttl=37 time=15.5 ms and docker run ....

I am currently involved in leaving a gig where I've been for a year now and I find myself breaking one of my fundamental engineering beliefs, in effect, engaging in an anti-pattern . If a pattern is what you should do for something then an anti-pattern is what you should not do . The anti-pattern I find myself engaging in is really, really simple; I am writing all new code in my last two weeks of work. Not fixing bugs or doing cle....

This post is a recipe for setting up a minimal Kubernetes cluster on Fedora without requiring virtualization or a container registry. These two features make the system cloud-agnostic and the cluster entirely self-contained. The post will end with us running a simple Flask app from a local container. This setup is primarily useful for simple CI environments or application development on Linux. (Docker Desktop has better tooling for develo....

Would you like to clearly understand what's happening when you use the Python import keyword? Do you want to use modules more effectively to structure your code? Or maybe you're ready to move to the next level with your Django project by adding user management. This week on the show, David Amos is back with another batch of PyCoder's Weekly articles and projects.




We’re busy preparing for our software engineering fall hiring season . Over the years we’ve done our best to make our interview process more transparent to candidates. While many candidates show up knowing something about what our interviews look like, much of the information floating around on the internet is outdated or wrong. These past few months have also changed a lot about the process as we’ve adapted to working from home and other ..

We are delighted to announce a new AWS Quick Start featuring Snyk Container and sample deployments for quickly and easily securing workloads running on Amazon Elastic Kubernetes service (Amazon EKS).

Do you find yourself struggling for hours to solve problems with Formik? I've started using a different library that's much simpler.

I went on a motorcycle trip. A fellow TOMCC 1 member was planning a solo trip to Campo Imperatore (“Emperor’s Fields”), the well known alpine meadow in the Apennine ridge. He called me as he was looking for some advice, and well, I ended up joining him. What sparked my interest was the destination, of course, because Campo Imperatore is a superb place to visit, especially on a motorcycle, but also Antonio’s peculiar take on the journey....

In this article, I explore an anti-hype opinion on service meshes and aim to provide a clearer perspective on whether they are the right solution for specific problems.

How does Grouparoo use Next.js to load pages and components from plugins to modify our web user interface?

Data is the fuel for intelligent decision making for both humans and machines. Just like high quality fuel ensures that jet engines run efficiently and reliably in the long run, high quality data fuels effective and reliable decision making.

The world has changed dramatically in just a few months, going from crowded bars and tourist spots to an almost world-wide lockdown. While we are still learning about the virus which caused this pandemic, we can clearly see the major impact it has had on our daily lives and the economy. In the fitness world, gyms are closed and people are actively looking for alternatives; trying everything from Instagram Live and YouTube workouts, to one-o..

Technology keeps progressing faster and faster. It’s accelerating. Or so I’m told. But is it really? How can we tell?

With today’s update we’re releasing a design overhaul for the settings (preferences) application. This overhaul will improve the look and reliability/consistency of this app which is core to Codename One. During this transition period we also have the ability to go back to the legacy UI for 100% compatibility but it will be removed. Common important features such as “Update Client Libs” are now available in the menu on the top right of th..

We’re excited to unveil Snyk’s developer-first prioritization capabilities, helping development and security teams prioritize fixes for security vulnerabilities in their open source dependencies and containers more effectively!

For developers, deciding which security issue to address first is hard, requiring time and expertise developers often don't have. This is a chance for the right tools to shine, providing the expertise to know which security questions to ask when prioritizing, and the technology to answer them quickly.

Outsourcing has put America in a precarious position. It quietly became one of the greatest threats to national security over the course of several decades, unrealized until the Coronavirus pan(dem)ic revealed the fragility of our situation. David Adler and Dan Breznitz, in the American Affairs Journal, discuss the issue and offer some concrete suggestions for fixing it. I encourage you to give it a read.

Normally when I'm trying to validate that an Internet service is available, well, I ping . Ping is one of those Internet bedrock protocols that I'm firmly in the camp of "SHOULD ALWAYS, ALWAYS, ALWAYS BE TURNED ON". But there are ping flooding attacks, etc so there are reasons why it isn't always a default (looking at you here AWS; staring you dead in the eyes with the 'ol stink eye). I recently realized that while it isn't example the ..

If you're building an app using GraphQL, picking a client to use can be hard. Apollo? Relay? Urql? Let's look into some options.

Docker runs as root. The programs executing inside containers too. Make it a bit better. # do everything you need as root (maybe installing some dependencies) # create a non-root user RUN addgroup --gid 1001 appgroup RUN useradd --create-home --gid 1001 --uid 1001 appuser # set new workdir WORKDIR /home/appuser # activate non-root user USER appuser # copy new files with correct permis..

Bitcoin seemed to stand alone in having a whitepaper that was dropped out of nowhere and having their founder disappear. Until Monero.

I went on an adventure today. I left behind the stable comforts of the terminal and compiled bleeding-edge Emacs that uses a native window system. This is a big deal for me. As long as I can remember, I’ve used Emacs from within a terminal. I’ve decided to give the GUI’d Emacs a whirl. My Journey I’m running macOS Catalina (10.15.5). Originally I tried using the pre-built packages via brew (brew cask install emacs) and those available a....

In our new series ‘Career Pathways’, we’ll share inspiring, real-life stories from our Thoughtworkers based in Australia on how they began their careers in technology, their learnings, and how their journey at Thoughtworks has continued to enable their career as technologists.Name: Garima Singh

While Thoughtworks hires technologists all around the world, our recruiters encounter similar questions from candidates regardless of their location. We asked recruiters from multiple countries for the most frequently-asked questions they get from candidates. Here are the top 7 FAQs.1. What are the main technologies that Thoughtworks works with?


Over the years, the world has seen remarkable and rapid advancements in technology which are deeply impacting society. Despite this, we continue to struggle with issues such as poverty, violence, and climate change. At Thoughtworks, we believe that technologists have a unique role to play in how we can positively impact society and push for a more equitable tech future.
