Despite big noises and lots of talk, most vendors aren't seeing a big pivot to IaaS. What is going wrong with the business model?

Researchers have devised an "absurdly fast" algorithm to solve the problem of finding the fastest flow through a network.

Flow Computing has developed a new computing architecture that combines parallel processing units with CPUs. By reducing the overhead of parallelization, the company claims it can effectively make a CPU 100 times faster.

pump.io is a software package containing a social networking service and communication protocol that can be used as a federated social network. Started by Evan Prodromou, it is a follow-up to his previous microblogging software StatusNet and its OStatus protocol. It is designed to be more lightweight and usable for general activity streams instead of the predecessor's focus on microblogging timelines, with its goal being to achieve "most of what people want from a social network".

Pleroma is a free and open-source microblogging social networking service. Unlike popular microblogging services such as Twitter or Weibo, Pleroma can be self-hosted and operated by anyone with a server and a web domain, a combination commonly referred to as an instance. Instance administrators can manage their own code of conduct, terms of service, and content moderation policies, allowing users to have more control over the content they view as well as their experience. It was named after the religious concept of pleroma, or the totality of divine powers.

Bento is a discontinued database application for Mac OS X made by the former FileMaker Inc., since renamed to Claris. Bento differed significantly from the company's flagship product, FileMaker Pro, in that it relied heavily on templates and integration with other applications. By default, Bento's data sources included Apple's Address Book and Calendar applications, which it could modify directly. FileMaker announced on July 31, 2013, that it would discontinue Bento on September 30, 2013.

I want to introduce you to a programming paradigm, that I discovered and that I have explored for the past five years: In Declarative…

We all have many kinds of features.

A semantic router is a pattern that enables AI agents to choose the right LLM for the right task, while also reducing their LLM dependency.

Many proposals have been made to add semantics to IP packets by placing additional information in existing fields, by adding semantics to IP addresses themselves, or by adding fields. The intent is to facilitate enhanced routing/forwarding decisions based on these additional semantics to provide differentiated forwarding paths for different packet flows distinct from simple shortest path first routing. The process is defined as Semantic Routing. This document provides a brief introduction to Semantic Routing.

When doing systems programming we often need to wait for something to happen. Common examples might be waiting for some data to come through a socket or waiting on a lock. We also often want to wait on any of several conditions to become true. A web server might be handling many sockets at once, waiting for any number of them to become readable or writeable. This short blog post is concerned with the latter scenario in Linux. Until recently there was no generic framework which allowed us to wait on many arbitrary events, but now there is, thanks to `io_uring`.

Essential concepts and practical applications

In many monolithic applications, transactions ensure consistency and isolation when making changes to the application state.

Modern JavaScript frameworks like React and Vue have popularized functional and declarative approaches to web development. While these frameworks have made creating dynamic web applications more accessible, it's worth exploring the potential of web components in this evolving landscape. Lit, with its minimalistic and declarative approach, stands out as an appealing base for leveraging web components in modern frontend development.

It’s easy to get carried away when you’re building a new web app. You’ve got big ideas, you picture millions of users flocking to your platform, and you start imagining the kind of infrastructure needed to handle all that traffic. So, you build for scale from day one—optimising databases, setting up powerful servers, and ensuring everything is robust enough for massive growth.

Today the Direct3D and HLSL teams are excited to share some insight into the next big step for GPU programmability. Once Shader Model 7 is released, DirectX 12 will accept shaders compiled to SPIR-V™. The HLSL team is committed to open development processes and collaborating with The Khronos® Group and LLVM Project. We’re sharing this […]
