i live in a pretty small place (as far as cities go), it’s not a small-small town, but it’s only 100k population spread out across quite a massive area

there’s still a few 800-1000 sqm blocks / established homes floating around the place, which i think would be ideal for myself and my future family

i can buy something established that needs some work for $450k if i’m lucky and find a good deal

i’ve always hated debt which is predominantly why i was asking this question to begin with, but it’s a bit of a stalemate situation

rent is ridiculous atm ($500+ AUD per week is the median here), so you can’t really save all that much while having to pay that (especially while i’m the sole income earner)

but then repayments on a home loan would be about the same for a $500k-ish home with interest rates where they currently are

but then it’s difficult to feel settled enough to start a family when you don’t own your home, or have stable living conditions (last rental we were in just sold at the end of the lease term, so we couldn’t resign, so forced back into competing in the tight rental market)

i’m stacking as much bitcoin as i can, so we’ll see where that gets me 👍🏼 (i’m just conscious that i’ll probably have to pull the trigger on purchasing a home some time in the next couple years so i can start building a family)

yeah, i’m looking for something a bit run down so it’s as close to affordable as i can make it, don’t mind something run down, and i don’t live too lavish at all either

still pretty expensive tho, would love for the market to cool down a bit, but who knows when that’ll happen

thanks for the words

serious question for home owners

how do you cope with being in the immeasurable amount of debt?

i want a house so bad, but the $600k minimum debt, getting shafted by arbitrary rate rises, and if the house prices shits the bed when you’re like minimum 80% leveraged - not good

but renting and not owning is so shit, and it’s currently blocking me moving forwards in life

i’m no expert, but studied statistics in uni, so occasionally i can know a thing or two - my take:

not a lot of people know about the “AI Winter” which was a period in the 1970’s where out of the hype of the 1960’s everyone thought it would only be a handful of years before artificial general intelligence (AGI) will be doing everything and anything

hype died down, funding died down, projects abandoned, etc.

same thing happened in the late 80’s and early 90’s too

this is not to say chatGPT isn’t really fucking cool, and that it’s not going to be extremely useful and valuable

clearly it will be, you just have to use it to figure that out, even if it just improves search and learning it’ll be a masssivvve win

BUT, i think it will be very good in some specific domains, then everyone will think that means it will be very good in all domains, but then we’ll discover that it’s still just not up to scratch in some areas

the cool part (i think) is that this process helps shine a light on things that are inherently and distinctly human, and a lot more complex to solve than it would initially seem at face value

i could of course be entirely wrong, and the future AI overlords will roast me for writing this message at some point in the future 🤣

time will tell ig

+1, definitely agree, i always have to jump in and add the @ sign at the start

hmmm but where do i actually get their keys from?

the link on the bitcoincore.org website guide for the builder keys is broken, so it seems like they've moved / changed that .txt file in the repo

(https://github.com/bitcoin/bitcoin/tree/master/contrib/builder-keys/keys.txt)

i had a look around and i found these:

https://github.com/bitcoin-core/guix.sigs/tree/main/builder-keys

but they look like way longer keys? with a different strucure?

hence all my confusion 😬😅

i did: gpg —verify SHA256.asc

but it’s giving me a bunch of “can’t check signature: no public key”

do i have to add all the dev keys somehow? 🤔

how do i confirm the bitcoin core release that i’ve downloaded using the individual developer’s keys (using gpg)?

i’ve confirmed the SHA256 checksum, but i’m unsure how to do all this gpg stuff

so, if i put bitcoin core on my fresh Ubuntu Server install, and start building out my node - is there anything i need to know about leaking my IP address or xpub or anything like that?

any node privacy best practices when setting up the config and shit? (for bitcoin core, fulcrum, sparrow, mempool, etc)

#[1]​ oh my fucking god i finally figured it out, so simple in hindsight it fkn hurts 🤣😭

so Ubuntu Server uses netplan, so you can just go into the .yaml and add the SSID / password where the other working SSID / password already was

i knew that, so i was already doing that, BUT

my password is the same across my 2.4GHz and my 5GHz network, so i just copy and pasted the password hash thinking it was the same fuxking thing, BUT

wpa password hashing takes the SSID as a fkn input too, which i did not know, so the same password, but used on a different network name (i.e. different SSID), actually gives a completely different hash for the password

makes complete sense, should have fucking realised it earlier

and you can get the correct hash by just going into your shell and punching in:

wpa_passphrase “yourSSID” “yourPASSWORD”

🤦🏻‍♂️

hmmm i’ll have a tinker around with it after work today

when i used “sudo iw dev wlan0 scan | grep SSID” (to scan for networks that my pi4 could see) the 5GHz was showing up

but it was just on attempt to actually connect to it that it all went pear shaped

i’ll try see if it’ll connect to the 5GHz on boot if in my netplan .yaml i put the 5GHz network first (not second)

if that works then i at least know it’s possible to connect to it, and 100% know that all the credentials are correct, and it’s just a matter of figuring out how to properly switch the networks while SSH’d into the pi4

how do you handle multiple wifi connections on a Ubuntu Server os that’s running on a rpi4?

i’ve configured it to connect to my 2.4GHz network successfully on boot, but then i’ve added the 5GHz network to my netplan .yaml, ran the netplan apply, and then i go to switch to that network “wpa_cli -i wlan0 select_network 1”

but it just hangs there (i.e. doesn’t successfully connect), and then i’m forced to manually reboot my rpi4 in order to get it back onto the 2.4GHz network so i can SSH into it again

🤔

how much does your infrastructure (and the skill of the workers needed to operate it) deteriorate while you wait for sense to win out? 🤨

it took me many days of fucking around as a noobie to figure this all out, but i finally did, and learned a bunch in the process!!

onto installing bitcoin core and all the other fun stuff now 😎

so if you have flashed Ubuntu Server to an sd card, booted from it on your rpi 4, but now you want to install Ubuntu Server onto your SSD that’s attached over USB storage, here’s what you do:

- wget “url.to.ubuntu.server.img”

- extract that file using “xz -d”

- use “sudo dd if= of= …” to flash the .img to your SSD (/dev/sda)

- mount the boot drive (probably /dev/sda1)

- then use “sudo cp” to copy the “meta-data”, “user-data” and “network-config” files FROM your sd card boot drive TO your currently mounted SSD boot drive

- then “sudo umount -l /dev/sda1” to unmount the SSD boot drive

- “sudo shutdown -h now” to shutdown the rpi 4

- unplug power from rpi4, remove sd card, and then power it on

- it should then boot directly from the SSD and then automatically use those files you copied over to preconfigure (i.e. “seed”) your os with the same wifi / SSD details that you used when you flashed the os to your sd card

so now you should be able to “ssh user@hostname”, then provide your password, and you should be running your fresh install of Ubuntu Server from your SSD!!

(“lsblk” to confirm)

you need three (3) main files to be present on your boot drive (/boot/firmware):

- user-data

- meta-data

- network-config

and the best part is, provided you want to use the exact same config that you used when flashing the os to your sd card, then those files ALREADY EXIST on the sd card boot drive!!

but, Ubuntu Server seems to run this “program” on boot called “cloud-init” which can preconfigure your os install with the correct parameters which enables you to SSH into the device on your home network after first boot

however, if you don’t have the ability to plug a physical SSD into your computer / laptop (i.e. a USB-to-SATA adaptor) then you lose the ability to actually install a headless os (like Ubuntu Server) directly to the SSD

or so i thought

so, it’s easy enough to use the Raspberry Pi Imager program to flash an sd card (or thumb drive) with the Ubuntu Server .img, and the program gives some handy UI to also preconfigure your os install with your wifi SSID + password, and also setup and SSH hostname + username + password too (and set the timezone)

what’s the problem? well, Ubuntu Server is a “headless” os, so it doesn’t actually have a UI, this means when running this os your only option is to SSH into your device (or physical keyboard + mouse but i didn’t have that option)

for anyone interested, this is by far the easiest method i figured out to get Ubuntu Server booting from your Raspberry Pi 4 SSD (if you don’t have a USB-to-SATA adaptor to flash Ubuntu Server directly to the physical SSD 🧵
