Thanks for the reply. I see parallels to the Web Audio API ( https://www.w3.org/TR/webaudio/ ) which is mostly for creating graphs of nodes using the browser's native code to do the processing. It's hard t

Does this support writing audio sample processing code in JavaScript? From the examples it looks like JavaScript code connects together pre-existing audio processing nodes, but it's unclear if you can write your own nodes in JavaScript

One reason why application containers are successful is because they eliminate the complexities of a single system where multiple services are running and potentially interfering with each other. There is no need for PrivateTmp= or some of

My understanding is that default unit files provided by the systemd packages are in /usr/lib where they can be read-only, whereas users can add/override them by dropping their own unit files into /etc (which is more like

Recently I have been wondering if systemd solves problems that are becoming less and less relevant to developers. New services are often deployed as containers. While systemd has a bunch of container-related functionality, it does not integ

For an even more lightweight approach to running containers in VMs see: https://github.com/containers/krunvm It's powered by https://github.com/containers/libkrun .

Do pods support queries or just HTTP GET/POST/PUT/DELETE? Queries are important for performance. They avoid transferring all data over the network from the pod to the application. Although it's possible to define an open

@anandchowdhary Can you explain the security implications of using Upptime? Does it need a token to access all of the user's GitHub repos? That's a little worrying because the code does not reside in the git repo it's fetched

This is an interesting idea. I found the "How it Works" page a little confusing and have tried to explain the core ideas in a different way here: http://blog.vmsplice.net/2020/12/understanding-peer-to-pee

Article author here. Thanks for mentioning it, I have updated the article to clarify that I'm a QEMU maintainer. The article was intended for the QEMU community but now that it's being discussed more widely it helps to be explicit

No. Coverity scans QEMU regularly but it is not sound. The challenge with static analyzers is that false positives make people not want to deal with the analyzer reports. I will check out IKOS, thanks!

Thanks, I have heard that MT Power Drum Kit is nice and have tried some Windows VSTs like TAL NoiseMaker and U-NO-LX successfully. I use the Gen1 Scarlett 2i4 and have also heard that later generations have some issues. My understanding is

For Ubuntu users there is AppArmor support in libvirt too: https://wiki.ubuntu.com/LibvirtApparmor QEMU runs on other operating systems like *BSD, macOS, and Windows. It is less mature on those platforms and it's safe

In theory file system drivers for this can be implemented for any operating system that allows third-party file systems. virtio-fs is based on FUSE, so a starting point would be existing macOS FUSE implementations (I haven't checked t

GlusterFS is a distributed storage system. virtio-fs is a shared file systems for virtual machines. You can expose GlusterFS directory trees to virtual machines using virtio-fs but virtio-fs itself doesn't do the network communication

You're missing the point. It says "insufficient on Skylake and newer CPUs". The Google Cloud blog post does not mention that retpolines are insufficient on newer CPUs. That omission is dangerous because readers will believe

According to this page retpoline is "insufficient on Skylake and newer CPUs, where even ret may predict from the indirect branch predictor as a fallback; those need IBRS". https://github.com/marcan/speculation

The centralized keyserver puzzles me a little too but it does have some advantages: 1. The email address adds a layer of indirection on top of your upspin directory and storage server addresses. You can migrate upspin providers without cha
