With the loss of Porthole due to Portage dropping support for Python 2.x, it's been a tough time trying to update my Gentoo system using only the command line tools. It was such a drag that I finally wrote my own Porthole replacement, which you can find the source code of here . It doesn't use any l...

I knew this GenPi64 thing was too good to last. So sorry to see you go Sakaki. You did an amazing job and we were so lucky to have your talented help for so long. Thank you so much! I wish you the best of luck at your new job and hope life treats you well.

I just right click on the "NetworkManager" applet, "Edit Connections," and set up my wired connection with a static IP address there. This seems to make stuff in /etc/NetworkManager/system-connections instead of messing with /etc/dhcpcd.conf. Maybe you should give the NetworkMana...

I wrote a very simple shell script to print the arguments and told gdb to use that as the compiler, which showed them ok. Then I thought, what if I call the compiler from my script? Lo and behold it compiled the code and gdb happily ran it! Wow, I had no idea to try something as crazy as that! Your...

Does anybody have a gcc/gdb combination installed that lets you use the gdb "compile code" feature successfully? This feature is supposed to let you write some C code on-the-fly while your app is running under the debugger, without requiring recompiling and restarting the app to test new c...

I bought 3 x USB 3.0 to SATA adapters on eBay. They all turned out to be JMicron based JMS578 devices with different firmware revisions. None of them worked worth a darn with my old Corsair FORCE 120GB SSD drive that I was hoping to use with the Raspberry Pi. Even with quirks enabled, it was still t...

So, admittedly, I'm a newbie at Gentoo. I was trying to get a version of FreeCell installed, any version, and was having a heck of a time finding anything that would work, as everything I tried seemed to be blocked by "keywords." After digging through Sakaki's documentation, I ended up add...

Thanks Sakaki. On the RPi Config Tool failing to launch on my system, I figured out why. I had edited /etc/sudoers configuration to require entering my password before blindly allowing super user priviledges, thinking that might improve my system's security. Unfortunately, the RPi Config Tool is sta...

demouser@pi64 ~ $ sudo systemctl disable pigpiod sudo: systemctl: command not found Sakaki's 64-bit Gentoo image doesn't use systemd. Looking around some more, I now see a symlink that looks promising: demouser@pi64 /etc/runlevels/default $ ls -l pigpiod lrwxrwxrwx 1 root root 19 Nov 22 2019 pigpiod...

I installed Sakaki's excellent 64-bit Gentoo image on my Raspberry Pi 4 with 4GB RAM. Everything works so far, and it seems a lot more smooth, faster, responsive, etc than Raspbian. I'm looking to make this my daily driver now and ditching Raspbian, as it is just so much better. One thing I noticed ...

When I was in university, there was always a formidable line to wait through to get time on a Windows PC. The line was shorter, sometimes non-existent for getting time on a Mac. And to use an X terminal running CDE, there was never any lines at all. Because nobody wanted to use an X terminal. It was...

Not sure - I haven't noticed anything particularly egregious in day-to-day use, but the image does rely on many of the same display components as (a 64-bit kernel) Raspbian typically does (fkms etc). Do you have a particular example that definitely exhibits the tearing in Raspbian, so I can try it ...

So, I gave the compton compositor a try. And yes, it does "fix" the screen tearing issue on my Pi 4. But it seems to reduce overall screen drawing performance. Dragging windows feels a little laggy. Video playback seems a little laggy and perhaps even dropping frames... So, I think I prefe...

Forgive me if this has already been answered, but does this 64-bit Gentoo avoid the screen tearing issue that we see in Raspbian on Raspberry Pi 4? If so, how was the issue solved (if you know)? The screen tearing issue is the one thing I dislike about Raspbian and makes me want to give this Gentoo ...

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...

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...

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...

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...

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...

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.

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...

Wow, good job! I've managed to compile gcc 9.2.0 and Qt 5.13.2 with the Qt 5.14.0beta3 qtwebengine on Raspberry Pi 4 (with 4GB RAM), but I have so far been unable to compile Qt Creator 4.9.2 or 4.10.2. Mine always seems to konk out with some errors relating to Qbs project file add/remove files inter...

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 b...

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...
