A look at why ScyllaDB completely bypasses the Linux cache during reads and uses its own efficient row-based integrated internal cache instead.

Our fancy WireGuard setup was accumulating stale peers. Here's what we did about it.

Today, we’re open sourcing Ozone, a tool that lets a team of moderators or curators collaboratively review reports, create labels, and inspect content on the atproto network. Later this week, we’re opening up the ability for users to run their own independent moderation services.

The pidfd abstraction is a Linux-specific way of referring to processes that avoids the race conditions inherent in Unix process ID numbers. Since a pidfd is a file descriptor, it needs a filesystem to implement the usual operations performed on files. As the use of pidfds has grown, they have stressed the limits of the simple filesystem that was created for them. Christian Brauner has created a new filesystem for pidfds that seems likely to debut in the 6.9 kernel, but it ran into a little bump along the way, demonstrating that things you cannot see can still hurt you.

Technical details on how Stripe built Ledger, a state-of-the-art money movement tracking system, including how teams at Stripe interact with the data quality metrics that underlie our payment processing network.

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.

An introductory paper to Ethereum, published in 2013 before its launch.

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.
