Re: What's the deal with rtlinux? Who exactly really needs

Outside of micrcontroller-like applications (controlling something mechanical or the like), for software applications such as audio: has anyone here ever actually needed it, did performance benchmarks and needed the RT kernel, with the stock kernel failing to perform? @curious, you just don't get i...

Re: What's the deal with rtlinux? Who exactly really needs

Seeing that people can't even agree if a RT kernel is needed for professional audio work on Linux in 2016 only strengthens my suspicions that it's another case of YMMV - your mileage may vary. So let's ask this. Outside of micrcontroller-like applications (controlling something mechanical or the li...

Re: Can I post about a cheap board in this (off-topic) forum

I see no problem with mentioning competing boards occasionally. For example when some other board might be a better solution for some ones project than a Pi for whatever reason. That might be helpful. Announcing other boards here gets a bit cheeky. Developing into a full scale discussion of a compe...

What's the deal with rtlinux? Who exactly really needs it?

I haven't used a real-time kernel. So the real-time Linux kernel seems to be well-supported on raspberry pis, and if you do a search you see many, many results. What I'm wondering is how important it is outside of like, robotics or controlling a laser or something, you know where a spinning turbine ...

Re: Can I post about a cheap board in this (off-topic) forum

Why would the foundation allow you to use the pi forums, off-topic or not, to promote what is potentially a competitor to its own products? Why not post on a another more generic electronics, SBC, or ARM based forum? If it's not raspberry pi related, is this the best place to promote your proposed ...

Other boards, and even KS campaigns, get discussed reasonably often. See the OT threads on PINE64, Orange Pi, Roseapple Pi, Lemon Pi, and various Hardkernel Odroid boards.

Re: Virtual machines as an alternative to sleeping?

Sounds very overcomplicated. Why not just boot in 4.5sec straight into the program and have your table in a 128MB file ? Are you going to change all the data in the table ? Do you really need the RAM speed for lookups, you have already used 4.5sec getting access to the table. When the VM shuts down...

Virtual machines as an alternative to sleeping?

Many people are exploring battery-pack related projects. As established previously the Pi has no sleep or hibernate functionality of any kind. At the same time, it can boot in as little as 3 seconds.

Nobody has tried it - thats all. Testing such a thing would certainly involve repeatedly compiling the Kernel and other parts of Raspbian and original research on (ARM ? Linux ?
