LIV2··on Australia concluded China was behind hack on parliament, political parties
One of our politicians has been caught taking money from a wealthy Chinese business man and another is tied to the propaganda arm of the Chinese government so you can guarantee there's a bunch more of our politicians owned by them that we will never hear about
LIV2··on DNS over HTTPS Explained
It will be interesting to see how chaotic it will be for orgs that have split horizon DNS or rely on search domains to resolve things.

I wonder how they're going to have to work with things like the Australian/NZ censorship which I believe is based on DNS?

LIV2··on Build a 6502 Computer
When I started with the 6502 it took a while to get a working, stable system due to a couple of weird circuit issues (like forgetting to qualify R/W by PHI2) which wouldn't have been the case if I was using a Z80

Do you know if there is a forum for Z80 homebrew systems?

LIV2··on Build a 6502 Computer
The problem is that the 6502 can only address 64K which includes ROM and IO Space so for any acceptable resolution you need tricks like bank switching and/or a seperate memory bus.

Even on the NES the PPU RAM is on a separate bus

LIV2··on Build a 6502 Computer
Nice!

6502's are fun to play with and relatively easy to put together a system with one.

There's still quite a community of us building new systems with the 6502 on the 6502.org forums if anyone is looking for more info re: programming/hardware, hints and tips etc

LIV2··on DevOps didn’t exist when I started as a developer
Haven't heard of Pulumi before your comment but will be sure to check it out now :)
LIV2··on DevOps didn’t exist when I started as a developer
Terraform is great but if you want to change to a different cloud provider you pretty much have to rewrite everything
LIV2··on Fancy Zones, a tiling window manager
"Power toys" predates Powershell and was a thing back when we were all using Windows 95
LIV2··on Debate in Austria over enshrining use of cash in the constitution
Looks like currently they're using Maestro and switching to MasterCard Debit which uses the credit card network

LIV2··on Debate in Austria over enshrining use of cash in the constitution
I'm assuming that their bank cards and debit cards are two different things

Presumably their "bank cards" only use some local payment scheme rather than visa or MasterCard (explaining why it can't be used online)

The newer "debit card" uses Visa or MasterCard which means it is accepted anywhere Visa/MasterCard is

LIV2··on Cryptographic key used to sign one of Facebook's Android apps compromised
Interested to hear this too though I doubt we will, they should probaby invest in some HSMs
LIV2··on SmartyKit Apple I replica
Most used the 6845 CRTC or compatible but the Apple 1 used discrete logic & shift registers instead of CRTC & RAM from my understanding

I don't think the particular shift registers etc are still available but it is still possible to do it with discrete logic these days

I guess different projects have different focus and some probably don't care too much how they get video as long as it works. I've built discrete and CPLD based video circuits for my own 6502 project which is fun but took months to get working perfectly

LIV2··on North American versus European distribution systems (2011)
From what I'm currently experiencing here (Sweden) three phases also allows for interesting issues like partial power outages that take down only some of your house... Never saw anything like this in Australia where it's probably the US style
LIV2··on How four packets broke CenturyLink's network
Is there a source or is that a guess at what happened? That sounds immensely incompetent to the point that I find it hard to believe
LIV2··on Why Finland leads the world in flexible work
Depends on whether you consider breakfast & fika to be work hours ;)
LIV2··on DNS-on-Blockchain is the next step after DNS-over-HTTPS
What is the proof? That the domain owner signed it with a certain key? Is that key shared out-of-band? If so why do we even need the blockchain?
LIV2··on Yubico launches its dual USB-C and Lightning two-factor security key
It can also be configured to require a touch for every signing action or even one for multiple signing actions within a 15 second window I think it is
LIV2··on Yubico launches its dual USB-C and Lightning two-factor security key
If you’re not using both slots you can move the credential to slot 2 so that it requires a long press before it activates
LIV2··on Virgin Media (UK) stores passwords in plain text, sends them through the mail
I’m a bit rusty and could be wrong but doesn’t MSCHAPv2/CHAP require knowledge of the plaintext password on the server side? I think that makes it required to be stored plaintext for any PPP connection and thus most if not all ISPs would be storing plaintext passwords
LIV2··on The market figured out Gitlab’s secret
Everything I hear about them screams immaturity, from deleting their prod db to smack talking competitors.
LIV2··on What Do You Call the Corner Store?
Aussie with a kiwi wife here. She says they only ever called it a Dairy

At least in semi-rural NSW I've only ever used "corner shop" or these days it's generally a "servo" but never a "milk bar"

Must be a Melbourne or Adelaide thing those guys are weird

LIV2··on Identifying Risky Counterfeit Intel Gigabit CT Network Adapters
Security requires availability which is far from guaranteed when using counterfeit hardware
LIV2··on Apple has pushed a silent Mac update to remove hidden Zoom web server
The government is bad, so is a trillion dollar American company choosing to collaborate with the government by enabling spying on their users just so they can make even more money. They're enabling a government to track down & torture/murder dissidents
LIV2··on PCI Express on the Raspberry Pi 4
While the ref clock is only 100MHz the data rate of PCI Express is much higher, it's a serial bus pushing multiple gigabits a second https://electronics.stackexchange.com/a/259002
LIV2··on RSA is a fragile cryptosystem
Indeed the whole point of smartcards are that they're portable HSM's, you can't simply clone a smartcard. You'd even need the pincode if you stole one and would have to use it before it was noticed/revoked.

Presumably there are some organisations that use smart cards for EFS encryption in windows but not sure if BitLocker supports it

LIV2··on Raspberry Pi 4 not working with some chargers
The linked article shows how it's due to a design flaw and explains why shitty cheap chargers/cables work but ok
LIV2··on Raspberry Pi 4 not working with some chargers
> Why?

Because two resistors in parallel (i.e when RD is shorted to RA) lowers the resistance and pulls the voltage down to a range that identifies the device as an audio device to the charger

Top is as the RPI is effectively configured, Bottom is how it should be.

LIV2··on Aussie ISP gets eye-watering IPv4 bill, shifts to IPv6
I had read that they aren't doing IPv6 on NBN connections though?

It seems that there has been a bit more adoption of it since I last checked which must have been a while ago, I'm surprised to see Telstra on the list!

LIV2··on Aussie ISP gets eye-watering IPv4 bill, shifts to IPv6
Aussie Broadband seem to be the only ISP that puts any effort in and cares about their customers, I hope they don't get bought and become another part of TPG
LIV2··on Aussie ISP gets eye-watering IPv4 bill, shifts to IPv6
It would be nice if the Aussie broadband market would start enabling IPv6 but the pessimist in me thinks they'll just turn on CG-NAT and call it a day.

Since most consumers don't care, and CG-NAT bandaids the problem I don't see how the market will be motivated to spend the time/money to bring us IPv6. We're probably going to be stuck with shitty bandaid solutions for a while
