The biggest thing for me is the meson build system. newlib uses autoconf-generated files checked into the build tree, with several different versions of autoconf used depending on directory. So you have to keep several versions of autoconf

The red content is intended to be supplied by a separate red LED. A red LED produces red much more efficiently than the phosphor on a white LED, so it saves power to leave red out entirely if you know it will be paired with red.

The loss of a higher buck ratio is not insignificant. It requires higher voltage rated mosfets which generally have worse performance, as well as increased switching losses resulting in more heat where you least want it. Most other use case

Comment 19 is 7 years old and doesn't reflect the contents of the patch that actually closed the bug, which enables HEVC both on Android and desktop when provided by the OS (but does not ship a software decoder itself).

>This is Fedora fighting against a patent troll which will cause a big legal hassle and then back off. For a patent troll sure, but what makes you think Fedora will win for a codec that from its inception has been explicitly nonfree?

In general you can convert any speaker layout etc to Ambisonics. For Atmos specifically, no, because there is no software decoder available for it (you have to bitstream it to a receiver).

by TD-Linux 4y ago
It is, in fact, Ambisonics (among other features). Though you don't actually need any of the fancy new stuff being worked on to use Ambisonics - you can already use Opus with Ambisonics today in MP4.

Over the last couple of years, yes. The GD32 and CH32V are increasingly popular. This is not so much ARM's fault directly though, as it is the complete unavailablility of STM32s forcing many companies to look for a quick replacement.

They still mechanically open the circuit breaker, which takes time.

Linux actually switched recently to leaving the whole bottom 1MB to the BIOS: https://lore.kernel.org/lkml/YLx%2FiA8xeRzwhXJn@zn.tnic/T/#u Apparently Windows now does it too because too many BIOSes are buggy:

The patents in question are a new level of terribad. So bad that they can be trivially invalidated by prior art. Nikon's going to spend a lot of money on lawyers but is likely to win (if they don't settle out of court...) (When re

Strictly speaking, only the claims matter, and so the text if those would need to be read and used to determine whether it can be invalidated due to prior art. The claims have very little to do with the diagrams supplied, rather they are ab

This is specifically IEEE Spectrum, and yes it is part for the course for Spectrum articles.

In my case, the big advantage is the automatic insertion of resamplers between different clock domains, meaning you can connect anything to anything. Pulseaudio tries really hard to make sure there is only one clock driving any connection g

I have been impressed how I've been able to make arbitrarily complex audio graphs in QJackCtl and it just works. I can even activate patch bays and it forces the audio configuration and applications (even browsers) stay happy. It'

Generally no, simply publishing is enough prior art to avoid someone else getting a patent. It can be helpful in indirect ways, like being more likely to be seen by a patent examiner. Alternately, you can license it under a defensive patent

WebEx (even in the browser) stars and stops the mic every time you mute and unmute and it works fine. There is no technical blocker.

I am surprised to see what I consider to be the most important part of signed integers in C and C++ only barely mentioned: >use of signed integers is better as it’s the only way you can get trap behavior for integers, as using it on unsi

The tradeoff makes sense mostly for many-party calls - for a 1:1 call sending multiple resolutions is a waste, but for a many participant call the downlink bandwidth usage becomes much larger than the uplink. You layer idea is called SVC an

Neat, I didn't know that the MPU fault handler was complete enough to allow for restarts. Now that the source is available, I took a look at what hubris does - it is not actually anything fancy, just a static list of up to 8 MPU region

I definitely didn't mean it as a feature request - blobs aren't actually that common in embedded (esp32 and some motor driver libraries are the most common exceptions), so I don't think it's important for adoption. In fa

It doesn't need to link any symbols, but I believe it does need to do relocations if the code isn't PIC, and to relocate the task's statically allocated RAM.

Another reason many games use Ogg Vorbis is for seamless looping and zero delay sound effects. Gapless MP3 is a bit of a mess because encoders insert priming samples but there is no standard way to signal it in the bitstream. (it also compr

I think the GP mostly answered it, but usually it's so that they are self-consistent with a set of design rules, and known to work. Every place I've done professional PCB work has had their own library. I think this trend comes fr

JAMMA arcade PCBs normally only use the -5V for audio opamps or DACs. The power amplifier is powered by the +12V rail (in a bridge configuration to provide +/-12V swings to the speaker).

There is a dedicated storage driver for zfs: https://www.jwillikers.com/podman-with-btrfs-and-zfs That said, the default overlay storage driver already supports reflinks, which will get you most of the benefits.
