DBOS Cloud is a transactional serverless platform that provides fault-tolerance, statefulness, observability, and cyber-resilience to TypeScript applications. Powered by the DBOS cloud-native OS.

When is a Markov chain useful for solving problems? When you want to model something that's in discrete states, writes David Eastman.

Nix and Guix are a pair of unusual package managers based on the idea of declarative configurations. Their associated Linux distributions — NixOS and the Guix System — take the idea further by allowing users to define a single centralized configuration describing the state of the entire system. Both have been previously mentioned on LWN, but not covered extensively. They offer different takes on the central idea of treating packages like immutable values.

Passkeys are the new way to authenticate more securely and without phishing risks. However, there are several subtle nuances that lead de...

We’ve talked about Ethernet basics, and we’ve talked about equipment you will find with Ethernet. However, that’s obviously not all – you also need to know how to add Ethern…

When I hear someone say "a Unix timestamp is in GMT" I die a little inside. It is muddy thinking that leads to many of the problems that plague this modern world. A time_t does not have a time zone at all. It is a point in time, a scalar value. A 'struct tm' is a point in spacetime, a vector value. If you are trying to express a point in time to a human, you could do that by saying ...

Enterprises are seeking new ways to extend security across distributed environments that include IoT networks, mobile workforces, and multicloud deployments.

QUIC is a UDP-based transport protocol that forms the foundation of HTTP/3. It was initially developed at Google in 2012, and became an IETF standard in 2021. Work on the protocol did not stop with its standardization, however. The QUIC working group published several follow-up standards. Now, it is working on four more extensions to QUIC intended to patch over various shortcomings in the current protocol — although progress has not been quick.

Things would go a whole lot better for server designs if we had a two year or better still a four year moratorium on adding faster compute engines to

Taipy is a free framework that lets Python developers, data scientists and machine learning engineers create web applications.

Policy-based control for cloud native environments

Rönd is a lightweight container that distributes security policy enforcement throughout your application.

Arista’s new network observability software aims to reduce human error, accelerate problem resolution, and streamline root cause analysis of network events and their impact on application performance.

After coming up against the limits of physics, scientists are rethinking chip architecture like never before

We’re building an open source alternative to AWS. For IPv4 assignment and firewall rules, we use Linux’s Netfilter / Nftables. This subsystem provides a powerful way to handle packets addressed to the host. We recently came across flowtables - a network acceleration feature in the Linux kernel that works like a routing cache. When we introduced flowtables into our stack, it reduced network latencies by 7.5%.

This post covers infrastructure improvement ideas for an existing AI application's architecture for better delivery, performance, and cost-reduction.
