The OpenSSH client and server are now available as a supported Feature-on-Demand in Windows Server 2019 and Windows 10 1809! The Win32 port of OpenSSH was first included in the Windows 10 Fall Creators Update and Windows Server 1709 as a pre-release feature. In the Windows 10 1803 release, OpenSSH was released as a…
By virtue of using LLVM, Mono has access to a wide suite of tools and optimization backends. A lot of active research uses LLVM IR. One such research project, Souper, tries to brute-force a search for missed optimizations in our emitted code. The .NET community may have software projects that benefit from using Souper…
The typical audio environment for HomePod has many challenges — echo, reverberation, and noise. Unlike Siri on iPhone, which operates close…
Today we’re open sourcing the FoundationDB Document Layer, a document-oriented database that extends the core functionality of the FoundationDB key-value store.
Here's an in-depth recap of debugging a GitLab issue that culminated in a patch for the Linux kernel.
CockroachDB 2.1 is 50x more scalable than Amazon Aurora at less than 2% of the price per tpmC. Read on to see performance benchmarks of CockroachDB 2.1, including the latest TPC-C results.
January 31, 2025: Post updated to clarify the reduced on-demand pricing and workloads recommendations. Just a few years ago, creating a database that could support your business at any scale while providing consistent low latency was a daunting task. That changed for me in 2012 while reading Werner Vogels’ blog post…
One of my favorite Amazon Leadership Principles is Customer Obsession. When we launched AWS Lambda, we focused on giving developers a secure serverless experience so that they could avoid managing infrastructure. In order to attain the desired level of isolation we used dedicated EC2 instances for each customer. This…
The experiments conducted from July until November at the Wendelstein 7-X fusion device at the Max Planck Institute for Plasma Physics (IPP) in Greifswald have achieved higher values for the density and the energy content of the plasma and long discharge times of up to 100 seconds – record results for devices of the…
I was particularly interested in one of the consequences of how dynamic RAM works. You see, each bit of data is stored by the charge (or lack of it) on a tiny capacitor within the RAM chip. But these capacitors gradually lose their charge over time.
A common problem that we have seen come up in several projects, is how to plot large datasets over time in an efficient manner using Qt. Here is one approach that we have found to work well in some situations, maybe it helps you out in your project.
Practical development throughout the evolution of Windows.
FoundationDB 6.0.15, our first major release since open sourcing FoundationDB in April, is now officially available!
Michael Dexter returns to update his blog post on the different file systems and details some key developments that are unfolding. He covers what's being added to these respective file systems: OpenZFS, Btrfs, and bcachefs. Michael Dexter has invested his volunteer time and career in Open Source hypervisors and file…
Linux containers, Kubernetes, artificial intelligence, blockchain and too many other technical breakthroughs to list all share a common component - Linux, the same workhorse that has driven mission-critical, production systems for nearly two decades. Today, we’re offering a vision of a Linux foundation to power the…
Unikernels are customized, single address space bootable images composed of an application and the required bare-minimum kernel functionality. Today’s unikernels have demonstrated substantial performance and security advantages over monolithic and microkernels, but none have yet achieved widespread adoption. The…
Imagine waiting for your flight at the airport. Suddenly, an important business call with a high profile customer lights up your phone. Tons of background noise clutters up the soundscape around you…
We have a cloud computing platform called Workers. Unlike essentially every other cloud computing platform I know of, it doesn’t use containers or virtual machines. We believe that is the future of Serverless and cloud computing in general, and I’ll try to convince you why.
At the heart of Meltwater’s and Fairhair.ai’s information retrieval systems lies a collection of Elasticsearch clusters containing billions of social media posts and editorial articles. The index shards in our clusters vary greatly in their access pattern, workload and size which presents some very interesting…
Since the point of these tests is to explore the performance of the Optane SSDs, the tests are configured much like the previous ondisk benchmark, using a database approximately 5x larger than RAM, to minimize the impact of caching in RAM and force the storage devices to be exercised. However, there are some twists to…
