The great majority of the software architectures currently in use are variations of the layered architecture, and what really sets them apart is the implementation details. Some might find this statement controversial, but in my experience, most software applications rely on code organized in layers to manage complexity. Some of the layers may utilize message queues or microservices, but that doesn’t necessarily make the architecture event or microservices based…

Recently I had a phone interview where I got asked a variety of Java questions. This kind of thing is standard, and most of the questions were somewhat standard: * What is polymorphism? * What’s the difference between a List and a Set? When would you use one over the other?

A complete rebirth of umbrelOS, engineered from scratch for unparalleled stability, UX, and security. Rolling out on March 18, 2024 for Umbrel Home & Raspberry Pi users, and in April 2024 for Ubuntu & Debian users.

Once upon a time you owned what you paid for, you controlled what you depended on, and your privacy and security were your own business. We think it’s that time again.

These days, you can’t throw a USB stick without hitting something that’s running Linux. It might be a phone, an embedded device, or your TV. Either way, it’s running Linux, and so…

Interactive introduction to grep with real-world use cases.

I wasn’t able to attend KubeconEU this week, but the 10th anniversary of Kubernetes was commemorated. We actually started work on…

Cliff L. Biffle blogged a great write-up of a debugging odyssey at Oxide with the title Who killed the network switch? Here’s the bit that jumped out at me: At the time that code was written…

In the middle of the 1980s, Apple found itself with several options regarding the future of its computing platforms. The Apple II was the company's bread and butter. The Apple III was pitched as an evolution of that platform, but was clearly doomed due to hardware and software issues. The Lisa was expensive and not [...]

When you deploy broken code, it may cause an incident. Then you’ll have to declare an incident. And don’t forget to create an incident so customers can stay informed!

The modern data lake integrates the data lake’s flexibility with the data warehouse’s structure while providing scalability and performance for both.

Solid state electronics have provided lighter weight night vision units that work better than the old-fashioned gear that used photomultiplier tubes, but there was an even older technology as [Our …

You keep using that word. I don’t think it means what you think it means.

60% of the time, it works every time

Scala has been with us since the company’s inception, and we are really satisfied with how it served us in all these years. In this…

Prolog programming language distinguishes itself from other programming languages because of several distinguished features. Explore what prolog is, its applications, advantages, and limitations.

I have found a lot of programmers that do not understand the Halting Problem and its implications, so here is my attempt to fix that.

With Threads starting to federate, there has been push back in corners of Mastodon, with some server admins blocking users from @threads.net entirely. I think just about everyone has complicated feelings about Meta, but I think this kind of move only harms users of the Fediverse. Adam Newbold has written about this, and I agree [...]

Nvidia earned its $2.2 trillion market cap by producing artificial-intelligence chips that have become the lifeblood powering the new era of generative AI developers from startups to Microsoft , OpenAI and Google parent Alphabet .

Twenty years ago, social media companies started telling us: “Hey, use this free digital mediaproduct!” We individually used it, or didn’t. And then we

On Monday, March 4, 2024, CITP and DeCenter co-hosted a workshop on the topic of decentralized social media. The invite-only workshop brought together a

esbuild and Redis1 are two examples of codebases with exceptional documentation. Through their READMEs, changelogs, architecture documents, and code comments, both projects explain their design in such a way that someone new to the codebase can understand where things are, how things are done, and why they are done that way. If you’re a developer looking to get better at documenting your code and software architecture, these are great case studies.

During the 1980s, a moral panic swept across the landscape with the mistaken belief that there were Satanic messages hidden in various games, books, and music that at any moment would corrupt the y…

Today's network environments are too complex to track by purely manual efforts. With digital twin technology, IT teams can build a virtual model of the production network and use it to validate configurations, simulate changes, and streamline management.

If your open source database is working now, why touch it? Because end-of-life software is harder to maintain, and you could miss out on valuable new features.
