Re: Why doesn't Raspbian have a Print utility?

Are you sure that you want to teach a 10 year old that killing trees should be part of his programming workflow? Actually, yes, you DO want to teach kids that printing is a very useful tool. While I do not do any printing normally nowadays, I do recall key points in my professional programming care...

Re: VLC in PI 4 - Opens in giant format beyond screen. Can't use it.

This is likely a problem with your monitor. I'm guessing you're using a TV that has an HDMI input. There are a number of such TV's that do not report correct physical screen size back to the computer. This messes up Qt's screen scaling calculations something awful. You can verify your monitor is mis...

Re: PI 4 USB audio clicks/pops

One thing that might be relevant is alsa reports that the only format my Boss GT-1 supports is S32_LE at 44100 hz. Under Windows I can also run it a 48k and 96k. USB fundamentally operates off of a 48MHz clock and this is not adjustable. 48MHz can be evenly divided to serve a 48KHz or 96KHz audio s...

Re: Is Raspberry Pi 3 B+ better than Raspberry Pi 4 B for USB DACs?

I'm using USB audio (Burr-Brown Japan PCM2702) on a Pi 4 and it's seems plenty good to me. Audio quality is crisp and clear, no noticable noise issues other than a slightly annoying thwump sound when the Pi is rebooted or powered down. But I think that's the fault of my USB audio device, not Pi 4. U...

Re: SPI Ethernet Port - An Unusual Problem?

I don't have any experience with OpenWRT running on a Raspberry Pi, but the last time I used OpenWRT on a buffalo router (many years ago) it was pretty bare bones and difficult to work with. On my Raspbian buster installation on Raspberry Pi 4, I can see that there is a kernel module available for t...

Re: Looking for recommendations of an audio library

Oh sorry, I'm using it with Qt and C++, not C. I use whatever backend happens to be active on whatever system I'm running my code on. On my x86 laptop, I think that ends up being JACK usually, unless I want to run my app playing alongside other audio apps (at increased latency), then I switch it to ...

So far the only library I have see that looks good is miniaudio I have not tried it yet but I have used RayLib that is based on it.
I've never used "miniaudio," but I have used RtAudio and it works pretty good for my purposes.

Re: SSH brute force attacks?

Why risk giving them even a few attempts before banning them? One thing I like doing is changing the port number that sshd runs on to something completely non-standard. Once you've done that, you can immediately ban anything attempting to access port 22, even on the very first try, as they've clearl...

The problem with "python3-pyqt5" is that it is missing "QtWebEngineWidgets", that I need to run ADMBrowser . And running... From what I can tell, Qt 5.11.3 currently in the Raspbian 10 buster repo doesn't provide a package for the QtWebEngine component... Which is really weird because it does provi...

Re: Mesa 19.2.0-rc1 available for testing

What don't you like about the file manager? We do customise it, so would be useful to know what you think any problems are. I've just compared with Nemo and TBH, don't see a lot of difference. Very similar in look feel and feature set. Mostly it's just because I'm very accustomed to Nemo. Digging t...

"sudo apt-get install nemo" did the trick for me. :) It's really great when buster has such nice things a...

Re: Pi 4 4GB- Wifi not working when resolution is set too high

Hey guys, I've got another possible workaround for your RPi4 WiFi problems... Turn off your Access Point. Reboot the Raspberry Pi 4 and get all the way logged into your GUI desktop. Then turn on the Access Point. Boom, WiFi connects and works, no need to switch to HDMI port 1. From my perspective, i...

I also experienced this rainbow color effect using the Warzone 2100 v3.2.1 binaries from the Raspbian 10 buster repo. However, upon compiling the v3.3.0 release from source code and the very latest master cloned from github, this rainbow color effect is eliminated for me in both cases (yay!). It's n...
