Data sent over the Internet will traverse a large number of smaller links. The combination of these links forms a path from the sender to the receiver. Sometimes data is lost when it traverses this path. For video and audio streams such losses can lead to playback glitches if not corrected.
So, what’s Amazon Elastic Container Service (ECS)? ECS is a managed service for running containers on AWS, designed to make it easy to run applications in the cloud without worrying about configuring the environment for your code to run in. Using ECS, you can easily deploy containers to host a simple website or run…
DragonFly version 5.4 brings a new system compiler in GCC 8, improved NUMA support, a large number of network and virtual machine driver updates, and updates to video support. This release is 64-bit only, as with previous releases.
I became involved in the nanomsg community back in 2014, when I wrote mangos as a pure Go implementation of the wire protocols behind nanomsg . I did that work because I was dissatisfied with the ZeroMQ licensing model and the C++ baggage that came with it. I also needed something that would work with Go on illumos …
via Chaos Engineering we discovered that there are situations where HTTP/2 will perform worse than HTTP/1.
As you can see from my EC2 Instance History post, we add new instance types on a regular and frequent basis. Driven by increasingly powerful processors and designed to address an ever-widening set of use cases, the size and diversity of this list reflects the equally diverse group of EC2 customers! Near the bottom of…
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…

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…
Security pros have been working on a new hardware attack type that exploits cache side-effects and speculative execution to perform privileged memory disclosure.
More than a billion people now use Facebook Messenger to instantly share text, photos, video, and more. As we have evolved the product and added new functionality, the underlying technologies that …
Grab designs fault-tolerant systems that can withstand failures allowing us to continuously provide our consumers with the many services they expect from us.
Now that MySQL 8 and PostgreSQL 10 are out, it's a good time to revisit how the two major open source relational databases compete against each other. Before these versions, the general perception has been that while Postgres is superior in feature sets and its pedigree, MySQL is more battle
The 3 - d acceleration feature of VirtualBox has had a bit of a rough time this year . One could argue that technically this component might not be considered attack surface in VirtualBox, due to the big warning put out in the documentation recommending against its use (emphasis mine):
