System Architecture

Docker has transformed the way many people develop and deploy software. It wasn't the first implementation of containers on Linux, but Docker's ideas about how containers should be structured and managed were different from its predecessors. Those ideas matured into industry standards, and an ecosystem of software has grown around them. Docker continues to be a major player in the ecosystem, but it is no longer the only whale in the sea — Red Hat has also done a lot of work on container tools, and alternative implementations are now available for many of Docker's offerings.

In this blog post I'll share my journey deep into the Linux networking stack, trying to understand the memory and window management of the receiving side of a TCP connection

Performance and tooling are frequently debated in the State of PostgreSQL survey, and this year was no exception. With psql remaining the number one tool for querying and admin among PostgreSQL users, we decided to compile a list of tools— that aren’t psql—to broaden your options.

We are very excited to announce Grafbase, an edge-native data platform for developers.

You want to measure software delivery performance, but don't know how?. Do you want to know if your team is performing well? Don't you know what to do to remain competitive? The answers to these and many more questions will be answered in this post.

DevOps is guilty of moving so quickly that security gets left behind. Lock down your toolchain or risk an attack.

Should devs build native applications for each platform, or take advantage of cross-platform development frameworks such as Flutter or React?

A few months ago, Equinix replaced the time-consuming and repetitive manual process for updating operating systems with an automated CI pipeline.

How do products become ‘sticky’? How do ad campaigns go ‘viral’? What differentiates genuinely successful businesses from those that fail?

Don’t just copy persuasive design. It will backfire. Here’s how to successfully build persuasive design into your larger strategy. Persuasive design elements like points, badges, reputation, and scarcity warnings are meaningless as stand-alone systems, but can be helpful in supporting a larger strategy as a use experience unfolds over time. For Persuasive design elements to …

While GUADEC, the GNOME community's annual conference, has always been held in Europe (or online-only) since it began in 2000, this year's edition was held in North America, specifically in Guadalajara, México, July 20-25. Rob McQueen gave a talk on the first day of the conference about providing solutions that bring some level of digital safety and autonomy to users—and how GNOME can help make that happen. McQueen is the CEO of the Endless OS Foundation, which is an organization geared toward those goals; he was also recently reelected as the president of the GNOME Foundation board of directors.

Forty years in, a protocol that's over the hill and under the gun, at least for the majors

A proof-of-concept docker image definition that can be natively built with the Docker CLI

Dockerfiles are a constant source of frustration in the container ecosystem. First, they are difficult to write (well). They can't express all types of build graphs – only linear graphs are easily expressible, limiting the amount of parallelism one can do (i.e., how fast your builds can be). Finally, they

A five-person team is responsible for steering the development of Python, but improvements are rarely straightforward.

Spend any time in complex systems and you know the first line of defense against tough-to-debug bugs is a reproducible process. You'd think that most software we write is reproducible – but there are many places where it isn't. Files get overwritten. Different machines have slightly different configuration. One step of

Every sufficiently advanced configuration language is the wrong tool for the job. For basic configuration, YAML or JSON is usually good enough. It falls apart when you try to do more: * Template it with a templating engine * Use esoteric language features to reuse code (anchors and aliases) * Patch or modify

I spent some time going over the Postgres schema of Gitlab. GitLab is an alternative to Github. You can self host GitLab since it is an open source DevOps platform. My motivation to understand the …

There are various design patterns used in UX Design practice. User Interface Design Patterns are used to choose the right input type, form…

Persuasive design isn’t evil. It’s a tool, and like any tool, it can be misused. However, with the right research and thoughtful application, it can be a valuable addition to any designer’s toolkit. Using persuasive design, social and psychological principles can be used to influence user behavior.

Just because people can do something does not guarantee that they will. Firstly, they must be motivated. Secondly, they must be persuaded to make decisions. Understanding the emotions that support the desired behavior is the key to conversion.

When used properly and ethically, persuasive design principles are powerful tools for building meaningful products that help people make better decisions and boost UX. #product #startup #tips #web #app #design #ux #ui

UX design patterns are reusable design components that are used to solve common usability problems that users experience.
