Re: Performance Buster on Pi 2

Hm, ok thanks for feedback, I guess the SD cards I bought are not that good then. I bought 6x TOSHIBA 256GB for 40$ each so I guess that might make sense that they are crap... :(

But it's only sometimes, so I'll let things run for a couple of weeks and see how things pan out.

Performance Buster on Pi 2

Has anyone noticed how laggy it feels in the ssh session. Many commands block for several seconds.

Re: java is not supported any more on Pi0 with OS buster

Ok, but how does one fix a broken installation? Uninstall the non -zero jre? Nope! Ok, it's obviously time for us to learn how to compile Java from scratch!

Re: Why are Raspberry Pi still using Java 8 when Java 11 is available?

Ok, so what is the fix?

Edit: openjdk-11-jre-zero apparently, if you want speed use an old oracle-java8-jdk because it was compiled with soft-float for ARMv6.

But but but, how does one fix a broken installation?

This is so messy.

Because 1.13 and above requires a 64 bit OS which is not yet available for the Pi4.
Do you know what requires 64 bit OS?

Re: Aeon Alpha

Sometimes the game just freezes X when started on the new Pi 4. Maybe it has something to do with audio: AL lib: (EE) oss_open_playback: Could not open /dev/dsp: No such file or directory Installing alsa-oss fixes that problem, the lockup still occurs. This is what happens in Xorg.log, I'm pretty su...

How come we can't get this working with 1.14.3 and OpenJDK 11?

Just cut the dongle with a knife... thug life!
The plastic switches to transparent before the circuitry is exposed so you can stop before it's too late... at least on mine it did.

Re: High Wattage Remote Relay

Ok, thanks for the input.

The last one I found apparently has some tricky setup because they ship them with the more advanced SPI remote.

The octal relays look like they are more what I'm looking for, but I wish they came with 5V and GPIO friendly amperage to operate.

Tricky this.

Heater, on/off very rarely. I really only found these so far: https://www.bc-robotics.com/shop/raspberry-pi-4-channel-relay-hat/ But I'm really concerned with their PCB and relay components, I'll probably loose the insurance using these.

Just before I start I know this is a touchy subject, specially with British that have very stringent electric security requirements so I will try to thread as carefully as I can. I'm trying to build a remote relay that can support >1500W AC. Now before you light this thread on fire, I know this is r...

Re: Java future on ARM

Do you have a public tracker for the software projects you are working on?

I'm very pleased to see the missing software to make Aeon Alpha run on a raspberry was fixed in about one year. (rpi audio and Java pulse)

But I cannot imagine what software is now still in limbo?

Re: Java future on ARM

@fruitoftheloom They don't have to support it, it's open source.

So when is the release of Raspbian Buster planned for?

@jamesh Yes, can I just add the debian repository to apt-get for that? https://packages.debian.org/buster/armh ... k/download
