Why are some programs still using jack ?

Reddit - Sat, 2017-08-19 15:59

It seems to me that most popular linux software (e.g. from things like skype and discord, to basically all linux released games to browsers like chromium and firefox) have abandoned support for OSS, ALSA and Jack directly and instead have chosen by vote of the masses to use Pulseaudio's API.

.. except for recording programs, from the professional~ish software like ardour to the smaller ones like guitarix, every single one of them is Jack depended. This makes recording on linux a bit annoying, especially since for some acursed reason jack has always been that one application that gave me trouble despite all my patience in trying to understand how to set it up properly. So I'm left in this weird spot where every time I want to record something I'm stuck in the cycle of:

Kill pulseaudio -> Now no audio app works -> Figure out why the jack startup script isn't working -> Record -> Need for some inspiration or a sample -> Kill jack -> Start pulseaudio -> ... etc

So I'm curios as to why certain programs are still using jack ? I understand that a few years back having things real-time might have been harder with ALSA and pa wasn't even a thing (at least not in a stable form), but isn't PA more than enough for RT sound processing nowadays ? Or at least as a second option for people who don't mind a few extra ms of latency ? Is it just that most audio software is unmaintained or no longer adding features ? Is there something that still makes jack superior to PA ?

Is Miracast still unusable on Linux?

Reddit - Sat, 2017-08-19 15:34

I can easily mirror my phone's screen with Android to my LG Smart TV, send videos and other things. But on Linux it seems impossible, I've tried with miraclecast but only works for the reverse use case (act as a sink not as a sender). There is a workaround but it's not something you want to do everytime. I've also tried aethercast that it's available in the ubuntu repo but it doesn't seem to do anything and the only documentation is for ubuntu phones.

Is that it, it's just something that it doesn't work on Linux? Do not suggest alternatives methods to connect to the screen.

Raspberry Pi Zero and Zero W: Linux computing in an even smaller package

TuxMachines - Sat, 2017-08-19 12:18

When the original Raspberry Pi (Rpi) became available in 2012, it was amazing that a Linux computer could fit in the palm of your hand for the low, low price of $35. On the other hand, if you’re a student without a real job, for which these boards were in part intended, $35 can still be a lot of money. To bring this cost down even further, the RPi team announced the RPi Zero in late 2015, which is available for $5, and even came as a “gift” on the cover of that December’s MagPi magazine.
