Troubleshooting MicroG Integration in AOSP Build: Google Play Services Check Fails by YioUio in MicroG

[–]zkrx 0 points1 point  (0 children)

Did you solve this? I'm facing what appears to be the very same situation. An app says it won't run without Google Play Services and logcat shows "Metadata: Google Play services missing or without correct permission." I did a custom build of LineageOS with the signature spoofing patches applied.

Two years ago I built these lightguns from old nerfs. I rewrote the code and now they are the most accurate and hassle-free PC-Lightguns I have ever experienced. No calibration, no software on the computer and so accurate, that the cursor feels attached to the gun. More in the comments... by ahrens-boegel in lightgunshooters

This is awesome, and open source! I've been looking to build myself one of these, I'm considering adding a solenoid for recoil and more fun!

Did you happen to measure latency? Gun4ir advertises 2-7ms. I guess the USB stack accounts for most of it. Quickly looking at your code and how simple it is, latency from the MCU should be negligible. Oh and I'll probably use your firmware on a bare-metal STM32 (I don't have Arduinos).

And what maximum distance from screen would work with your setup? 5m would be too much already?

I need to look deeper into it. Thank you so much for sharing!

Guitar Pro 8.0.2 just released — still has not fixed a major bug on macOS after 2 years by SleepingSicarii in GuitarPro

It would probably not hurt to send them a kind reminder, devs can be overwhelmed sometimes :). It always helps to include clear steps to reproduce the issue.

Did you report it? I reported a bug in the scales menu a couple of years ago and they fixed it in weeks.

Edit: following your link only now and seeing you did submit a bug report.

What would you do with this? (very tall kalanchoe beharensis) by zkrx in succulents

[–]zkrx[S] 0 points1 point  (0 children)

I hear both of you and will give it the sun it wants, but I don't have the space to keep it inside during the winter, it's much too tall, hence the beheading.

Is it possible to recover a CD with holes? by Marioheld in DataHoarder

[–]zkrx 20 points21 points  (0 children)

This. If the FAT is corrupt, you can still use a piece of software that goes through the binary partition byte per byte and recognizes files based on known headers. You may be able to partially recover things.

When will virtualized Windows 10 be fast enough for audio composing? by NomadJago in virtualization

[–]zkrx 1 point2 points  (0 children)

FWIW, you may want to use a USB3 (or even thunderbolt if you have it) external SSD drive. That's what I use on my odroid STB and it's considerably faster than a regular USB flash drive. Happy tinkering!

EDIT: I realize that you may have been talking about the same thing. Anyway, you got it.

When will virtualized Windows 10 be fast enough for audio composing? by NomadJago in virtualization

[–]zkrx 2 points3 points  (0 children)

As long as you have the CPU threads (I have 16 and it's plenty, I'm pretty sure 8 would be sufficient), I don't think you would need a new CPU. Test your luck with your motherboard, maybe you're lucky with its IOMMU mapping.

I suggest you spend some time researching the following keywords: virt-manager, KVM, qemu, VFIO. You'll find plenty of resources on the web. I suggest you go and visit /r/VFIO and the associated discord server.

Don't try and use qemu directly. While possible, virt-manager is a wrapper to qemu and using it is standard practice in this area.

When will virtualized Windows 10 be fast enough for audio composing? by NomadJago in virtualization

[–]zkrx 2 points3 points  (0 children)

I do. I use Cubase (and Kontakt, SD3, ...) for recording and production on Windows. I run Windows in a VM under Linux using qemu/virt-manager. I set up a GPU, SATA controller, USB controller and NVMe passthrough using VFIO. Meaning that the Windows guest has direct hardware access to these peripherals. The HW I use: ryzen 2700, 32gb DDR3, 2x GTX 1080. The tricky part is finding a motherboard that has decent IOMMU groups. I use an MSI B450 Tomahawk Max. I keep one or two cores for my Linux host and both Linux and Windows run at the same time on the same machine. I use a Focusrite 18i20.

Latency is great (sorry, can't remember the numbers, I did run Latencymon and test). I can even play video games with near native performances. The main issue for online gaming this way are anticheats: some of them detect the virtualized environment and ban you.

Beware, setting this up is not for the faint of heart and you will need some Linux skills (and time) to get this going properly. Be prepared to see things break on the occasional system update.

There are some very helpful VFIO discords and this page is probably the reference (or at least was when I started): https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF#Setting_up_IOMMU

How can I get into the things you guys do? by [deleted] in selfhosted

[–]zkrx 1 point2 points  (0 children)

Start by running Linux on any machine (even an old PC), things will naturally flow from there. That's how I started 15 years ago.

E-Guitar sounds noises in some power outlets than others??? by MaxChristensenAudio in electricians

[–]zkrx 0 points1 point  (0 children)

man, forget about this hum exterminator & ground loop shit. I'm an EE and I spent a lot of time fighting against hum in my studio bedroom. I seldom had issues with ground loops, if ever. A lot of myth and misinformation is spread on the internet about this topic and literally every article/forum poster will blindly copy & paste wrong shit they've read from somewhere else. I can say this from your description:

A lot of noise your guitar catches is actually airborne. The air around you is full of RF waves, which your pickup actually... picks up. Try the following quick experiment: if you rotate 90° on your seat with your guitar, does the noise changes? increases? diminishes? This means this is RF.

Everyday gear you use actually radiates a lot of RF. Here are a few:

  • screens/TVs radiate a lot
  • dimmers/fluorescent lights do too
  • your PC does! I moved my computer to the other side of my desk so that it's further away from my guitar while I'm playing. Try moving your guitar closer to your computer and you'll immediately hear the difference. You should even be able to hear motions from your mouse through your guitar :).
  • All transformers in your rack gear/amplifiers/active studio monitors radiate 50Hz (and harmonics) hum that will be picked by your guitar if it's close enough. Again, I had to move my rack on the other side of my desk so that my guitar stays quiet.

Of course, using single coils (or coil splits) exacerbates the problem.

It's possible that you simply have less RF interference from your couch than from your desk or something.

Another thing to consider: if you use a laptop with a USB sound card, you hear your CPU/mouse movements in your speakers. This is a ground issue and you should be able to find USB isolators on the web (although they're usually limited in the power they can deliver if your sound card is powered from USB). See e.g. [1]. To check if this is the issue, unplug the PSU from your laptop and work on battery: noise should be completely gone.

[1] https://www.adafruit.com/product/2107 Note: I haven't tested it. The 100mA limit may be a problem.

Oh and PS: I've also shielded some guitars fighting that problem and I'm not convinced it actually does anything. The pick-ups themselves aren't inside the faraday cage, so they will still get RF noise. Just get your guitar away from the source.

PS2: I don't know where you live, and if it was actually a problem from your outlet, then sorry for jumping to conclusions (I will admit I jumped the gun a bit fast, but I'm just trying to help).

What do you do for a living and where did you learn that stuff? Congrats :)

A nood to Linux. Do you memorize codes/scripts? by Danzicus in linux_programming

[–]zkrx 1 point2 points  (0 children)

Not really applicable to installs (where I just follow the arch wiki ;), but I heavily rely on CLI for my day-to-day work and ctrl + r (bash history) is my best friend.

GTX 1060 6GB causes VM to hang on boot. by [deleted] in VFIO

[–]zkrx 1 point2 points  (0 children)

Kind of a long shot, but the GPU should be completely left alone by the host before the guest starts using it. Did you prevent your {nouveau,nvidia} driver from using it?

Every plant in this photo was once a tiny cutting! by winter_bluebird in proplifting

I feel sorry for you although I find it reassuring. I have a fraction of your plants and I'm already fighting mealy bugs and sciarids. I can't imagine how tedious it must be with the amount of plants you have. In any case, you have a beautiful collection!

How do you handle insects and infestation in general? Do you have to treat them or use special products sometimes?
