Re: RPi 1, RPi 2, RPi 3 vs. OPi 1

Well, you need multicore support; the way I do microservices everything can run anywhere, it's the only way to scale and make a distributed system fail proof. So when I deploy any code it gets broadcasted async to all nodes, same with data! That sounds like a problem only because most systems are su...

Re: RPi 1, RPi 2, RPi 3 vs. OPi 1

Ah, so you are reinventing the async wheel for Java. Async programming like that is what we have all been doing with node.js and Javascript for years now. Of course async programming in JS is much easier as JS was designed to be async from the very beginning. Node.js is 100% async unless you go out...

Bullen, I'd appreciate it if you could explain what you mean by "async-to-async headerless HTTP" I think I get the "async" part but HTTP is pretty much defined by it's headers.

Smart watch irony, with a tiny logic of responsibility. I actually sleep better if I get punished by my mistakes, a bit insane, but still true. My system uses async-to-async headerless HTTP with "less headers" to synchronize all the nodes concurrently. This means zero IO-wait and scales great on sma...

Re: RPi 1, RPi 2, RPi 3 vs. OPi 1

@jamesh Absolutely, I was just so happy I got anything to work on the board at all.

Armbian has come a long way!

Also remains to be seen the stability long term both on the hardware side (physical failures) and software side (kernel panic, memory leaks etc).

But so far it seems to work fine.

Re: RPi 3 SoC at nearly 100 °C, reporting 80 °C

Preliminary results (without testing the RPi3 yet) CPU + eth on the Orange Pi One is 2x the RPi 2! This means Raspberry Pi products are 6x less performant per power/ price. That is 600%! Unless the OPi One SD card speed is crap or the power consumption is completely bonkers (both unlikely) we have a...

Re: RPi 3 SoC at nearly 100 °C, reporting 80 °C

Hmm, my Pi3 works fine. Extra performance, no heatsink, no problems with bandwidth. It's just faster. 40nm was the cheapest option. Going to a smaller process was too expensive. It's basically a chip redesign - you don't just change a number in the fab, you need lots of reworked blocks that work at...

Re: RPi 3 SoC at nearly 100 °C, reporting 80 °C

Also the RPi 2 was already hitting the bus limit, there is no point to have a V8 engine on a tricycle. I don't think that's true at all. Overclocking experiments on a Pi2B have returned almost linearly scaling benefits with increasing CPU, GPU and RAM clock speeds in benchmarks for me. By default, ...

Re: RPi 3 SoC at nearly 100 °C, reporting 80 °C

Well, if you are not happy with it, send it back. But consider first - the cores have changed to give 50% extra performance, and that performance produces heat. Did you expect the same thermal behaviour (not physically possible btw)? All Pi's use the same governor system, so when they get too hot t...

Old updated SD card with Jessie? That does not compute, Jessie was released a few weeks ago.

There should be clear instructions that you need jessie to run RPi3.

There are official people on this forum, this is a nobrainer.

Ok, you need to install a fresh Jessie it seems.

Maybe it's because I used the same SD card for my Zero?!

Re: Early RPi 2 randomly segmentation faults process

Exactly, so I'm trying to figure out if it's a one time freak occurrence or if others with early RPi2 from the white black latch factory are seeing failures too after 1 year of 24/7 operations.
