6. run:
7. fix raspberry pi configuration
8. reboot
9. search for and uninstall all bluetooth packages, reboot (search term: bluetooth)
10. search for and uninstall all wireless packages, reboot (but don't delete wireless tools - library or you'll lose the gui) (search term: wireless)
11. search for ssh and uninstall all of the server packages, reboot (search term: ssh, but only choose the server packages).
12. search for vnc and uninstall all of the server packages, reboot (search term: vnc, but only choose the server packages).
it should now boot with no bluetooth icon at all and with no wireless interfaces, as well as with no remote access.
i then stopped to sleep and removed the tinfoil and turned the device off when i did.
when i woke up, i turned the device back on and plugged an ethernet cable in to make sure it connected. i have it set up to connect to a reserved ip on my router, as determined by the device's mac address, but it's just running dhcp (by default) on the device. wait for the update icon to come up, and install all of the updates. reboot.
the next step was to update the /boot/config.txt file, as per the posted video, with the aforementioned update code. these are the lines to change:
# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
dtparam=i2s=on
#dtparam=spi=on
# Enable audio (loads snd_bcm2835)
#dtparam=audio=on
dtoverlay=hifiberry-dacplus
# Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d, noaudio
max_framebuffers=2
after a reboot, make sure to choose the right audio device by clicking on the sound icon at the top right.
i then streamed the first mt zion record to check to see what it sounded like and was pleased to hear that it recovered it's headroom; the lowpass was gone. great.
4:15
i then spent a few hours on the bicycle, listening to a few early godspeed records. i picked these records because i know they have a wide harmonic spectrum and because i know them extremely well; these are records i've certainly heard hundreds of times and have maybe even heard thousands of times through headphones or high quality systems and that i consequently knew i would be able to very quickly judge the sound quality of at extreme volume levels. if something was muffled or blurry or some frequency range was cut, it would be immediately obvious to me. now, this is not a technical analysis, and perhaps somebody might find a dac that has better specs, but i was trying to fix an obvious audible defect and i can state with some force that these records sounded outstanding streaming from youtube over hd and out into my amp, and then into a 4 speaker setup that includes two vintage kefs and two vintage celestions. i couldn't hear any noise. moya was fucking immersive. i hope the kids upstairs enjoyed it (</sarcasm).

i stopped this morning not long after the last post in order to eat and then to sleep and then woke up around 11:00, in order to once again wait for a package, this time the one with the two switches and the two usb hubs. the package did arrive early in the afternoon. i was able to get on the bicycle for more gybe from 14:30 to 17:30ish, stopped to eat again around 18:00 and then intended to spend a few hours cleaning before showering and then sitting down to finish this write-up. i am just getting back to finishing the narrative, now.
where was i?
as mentioned, i spent the 26th cleaning. i then spent the 27th and 28th fixing vandalism in this post. the usb hub for the pi is in, but i haven't touched the actual device; i have been listening to di meola through it, streaming in hd from youtube, and it sounds great. di meola is a good test artist because it provides for an opportunity to listen to the overtones on the guitar, which is exactly the kind of thing i'm using the pi to rescue.
the overtones from al's playing on these records are distinct through this signal and...overtones are not clear. that's the point. you can really hear the decay on them, though. as mentioned, the specs may not be spectacular, but i've spent enough time with sound (and with a neurotic audiophile father) to know that specs are useless. i am knowledgeable about sound (as a musician), i have good ears and i'm happy with the outcome.
the last thing to do before i can put the pi back in the case is ascertain if i can use the kvm or not. i'm going to swap out ports and cords and see what happens. i haven't further altered the software or have further steps for the install, yet.
3:00
unfortunately, the kvm seems to continue to be providing easy outside access and i don't quite understand it. this is not a wireless device and it shouldn't have any sort of wireless access at all.
i suppose i'm not going to be able to use the kvm, then. i have extra usb mice and keyboards, that's a minor annoyance.
i suppose i might consider purchasing a new kvm, but it's not helpful if i don't understand how it's being used to connect to the pi. that doesn't strike me as script kiddie stuff, that actually sounds more like organized crime hacking. that would require some kind of advanced emi interference.
3:53
hacking is boring.
i'll just avoid the device and do something less boring, thanks. problem solved. next.
3:58
the kvm switch isn't causing problems on the windows 98 machine. granted, there's no network connection on the 98 machine, but that's an absolute pre-requisite on the pi.
(yes, i have a windows 98 machine in my studio because it has a 16-bit soundcard with an onboard effects rack)
it also strikes me as somewhat odd that the thing gets hacked every time i plug it in, almost instantly. is it broadcasting? are they sitting there 24/7?
it seems like it's obviously being instantly remote controlled, but if there's something wrong with the cord, it could have a similar outcome. i could be assigning order to chaos. i don't think so, but i need to be thorough.
let me try the xp machine.
5:27
the way i have it set up right now is that the video is going through the kvm and the mouse and keyboard are separate through usb 2.0.
this isn't what i want; i want it all connected through the same mouse and keyboard.
5:28
am i done with the pi now, though?
tentatively.
if i'm not using the keyboard or mouse inputs, that's it. it's done.
5:31
yeah, i had some weird experiences with the xp machine last year, but it's not being remote controlled. again, the xp machine is air gapped, like all the pcs in here.
hrmmn.
is it actually the cable, then?
5:47
if i connect the keyboard and mouse directly to the pi through the cable, it functions properly.
oddly, the pi never reads the keyboard or mouse when you plug it in directly, you have to unplug and replug the mouse in and sometimes it doesn't read the keyboard at all. it makes you wonder if the channel is getting captured over the plug, but if it needs the kvm for the exploit.
*shrug*
i'm going to get some rest, and decide if i want to buy a new kvm or not in a few hours. clearly, this one is causing me some problems.
i don't want to figure it out and block it, i want to unplug it altogether and spend my time doing something more enjoyable. i have at the least tied the issue directly to the kvm and directly to the pi, or at least directly to the usb side of the ps/2<---->usb conversion.

aug 30, 2023
i intentionally slept all day today because i needed to catch up on it and then spent all night scraping off the consequences of the last week's worth of caked on makeup, including taking two showers. now, it's 3:00? time just disappears sometimes.
whatever i'm actually experiencing with the pi, the adapter i purchased isn't what i want to be using:
The vast majority of commonly available ps2 to USB converters are simple passive ADAPTERS that simply change the plug shape to match the outlet. These ADAPTERS only function to connect the ps/2 wires to the approximate USB wires. Simple ps/2 to USB adapters do not use specific software drivers.
In general, most users having trouble connecting their keyboard to newer computers are looking for a ps/2 to USB signal CONVERTER. These devices use an integrated circuit (pre-programmed chip) to actively translate the ps/2 keyboard signal and convert it into a USB keyboard signal.
in fact, i checked the amazon product page for the adapter i bought and there are a lot of complaints about it. i was able to find a converter with a lot of comments that it works, including the exact combination of a kvm to drive a raspberry pi. i'm going to need to need to try this next.
in the long run, the pi may end up connected to the monitor i'm currently using to watch lectures when i eat instead of the recording room monitor. if the second adapter doesn't fix it, i should consequently not replace this kvm, but stick with the external mouse and keyboard for now.
i suppose that's the end of this, then, or for now. i'll need to take everything apart, untangle all the cords, put everything back together in a cleaner and more organized way and move some of the external drives over to the stereo, from the table near my bed.

did i sleep or clean on the 30th? i think i probably did a little of both, and then got some more bicycling in. i've been fighting with potheads upstairs this weekend. they think they're gangsta, so i've been blaring the benny goodman and count basie. that's real gangsta. they seem not to like it, indicating that they're really poseurs. i've been struggling with finishing this post and cleaning ever since, but i do have a few updates to provide to finish this up. i think my converter is in on the 5th.
i don't remember what day i took this picture on, but this is a convenient place to leave the pi, i think. also pictured is the usb hub and an old sansa mp3 player.
unfortunately, the pi cannot be put to sleep. what can be done instead is to decide on a collection of tabs and then instruct chromium to load the last session on restart. when you boot back into the pi, you can then re-open chromium to carry on the session, like you're waking the machine up.
i don't need that update.
the system is relatively responsive, for a phone, which is what this should really be compared to. it's like installing linux on your samsung or nokia and sending it out to a monitor, except it also has a stereo-system quality sound card.
i listened to {e} this morning and it sounds correctly, finally. i think i realized it was a volume issue, but turning it up was only partly effective. i'm going to be be back to listening to my discography while exercising relatively soon, but i'm going to move forwards, this time. right now, i want to catch up on the constellation records catalog.
i will be using the pi as a streaming device for exercising more than anything else, but it's also connected to the 4-way speaker system, meaning i can listen to it while in bed, typing. this is also a pretty intense system for sex, if i ever let any men down here, which i never do. i'm very picky about men, and tend to prefer to have sex somewhere other than where i sleep. it's true, though; this is a little sex pad down here at this point, and i'm becoming cognizant of it.
the cd player is still connected and i do still use it fairly regularly but the reality is that most music gets streamed nowadays. i was looking at hd streaming sites, and the best quality streams are actually for free from youtube. i'm consequently very likely to stick with the combination of youtube + bandcamp, rather than move to any sort of paid streaming platform, due to quality issues and due to royalties issues. i actually want to start buying more physical cds, again.
there is a record player in the other room, but it's not connected to anything, and i don't have any records any more. i used to have a collection of 70s jazz, prog and fusion records, but i haven't held on to them. there are some things - like mild oldfield - that sound better on vinyl, but i actually generally prefer digital production to analog production. it's always frustrating to try to explain to pro-vinyl people that the reason they prefer the older technology is technically that it sounds worse; their ears prefer the noise and the harmonic distortion to the cleaner digital signal. there isn't actually a correct answer in generality. it depends on the recording.
14:34
these are some pictures of the desk, with the pi in the corner. the two twoers are the 32-bit and 16-bit production machines.
the pi will be connected to the music review youtube account,
i will have access to the deathtokoalas blog from that account, and will be doing show and record reviews from the pi, as i rebuild the blogs and narratives in pdf formats.
15:28
i am assigning each account to a different device. the chromebook-tv in front of the couch is connected to the koala oversight committee account (which replaces the 90s pc, which can no longer connect to youtube), the linuxbook will be connected to the blogging and vlogging accounts (which replaces my fried hp laptop) and this chromebook will be connected to the music production accounts (which takes over that function from the now air gapped xp production machine, which also used to act as the streaming device, which is something this chromebook cannot do effectively).
i know this is a slow process and that i haven't been very productive while i've been doing it, but the reality is that i lost a substantive amount of my hardware a few years ago and that it's been a difficult and frustrating process in slowly replacing it.
15:33

i'm caught up on this, now. i've been struggling with cleaning myself up this week, and it has taken up a lot of my time. my face is frustratingly dry, unfortunately; i've been struggling to sufficiently moisturize. i need to do some filing on the other machine before i move the mp3 drive over, and the converter will hopefully be here on the 5th, which should clean up the space.
i can think of three further issues to consider:
1) if the pi is almost always on, can i install a security camera? can i use this with zoom?
2) can i lock the pi's screen?
3) i have been using chromebooks in guest mode for so log that i've forgotten about browser extensions. i should be able to go back to normal ad blocking in chromium, right?
let me get something to eat, first.

the converter fixed the kvm issues. great.

sept 9, 2023
the converter package also came with some new exercise bicycle clothes, so i can actually wash my bra between uses, and which is what this raspberry pi music streamer is mostly being used for.
before exercising:
and after three hours on the bicycle, looking a little rough until i can get in the shower:
my hair is growing. it's almost manageable, finally.
i got distracted doing an update vlog, but intend to finish this in the next few hours.
