On the , "RANDOMIZE USR nn" is the usual way to launch machine code when you don't require any parameters or return values.

But why did they use RANDOMIZE, and not GO TO or GO SUB?

Always seemed a bit of an odd choice - anyone know the history of this? 🤔

peter,
@peter@area51.social avatar

@retrotechtive usr was a function which returned a value from a machine code call.

I think randomised was used as it didn't care on the result as usually the call never returned

#StarTrekDiscovery Season 5's Captain Rayner Ran His Ship Like a Pirate

https://collider.com/star-trek-discovery-season-5-callum-keith-rennie/

"Like, say Battlestar, when I started on that I had no idea where that one was gonna go. Discovery was already very established, but I actually didn't let any of that into my [head], because I went, 'That's not gonna help.' So, I didn’t. Now, I'm feeling the world of it. Now, I'm sensing what the world of Discovery is and how many people love it, and how it fits."

I've been gut-punched by the demise of the . It was the first processor I coded directly on, and was the CPU in my first ever owned computer. I'm actually writing code on it right now, and it really does feel like losing a part of my personal timeline.

Goodbye old friend, your absence will be felt.

peter,
@peter@area51.social avatar

@retrotechtive it was the second processor I wrote assembly on after the 6502, but I fell the same.

That said there will be alternatives, the retro community will find a way

An end of an era?

The Z80 product line, specifically the Z84C00 is being end of life after 48 years of production.

As usual for Zilog, nothing on their website.

This I got from the RMC discord but I did see this earlier today elsewhere

We are making some progress on the SIM stuff. All OK as proof of concept, but integrating with our systems step by step to be a service for trialists this month. Getting close.

The same SIP2SIM logic for calls and texts, but for (expected) £10+VAT/month. But no "airtime" cost either way for voice or text.

Data packages to work on but seem sensible,. hope to have news on that soon. Just normal NAT mobile data.

I have been working on SMS all day, nearly ready.

@aaisp @revk if you need a tester just ask, as still not sure what to do when the existing service ends this month & not found a suitable replacement so far

peter,
@peter@area51.social avatar

@revk @aaisp nice, looks like it might even be better than the original 😉

peter,
@peter@area51.social avatar

@revk @aaisp the cost of each call to the handset might have been an issue but if that goes then the higher monthly cost might make some use it more if they don't need to worry about that extra cost.

Especially if it's internal calls within their own PBX

peter,
@peter@area51.social avatar

@awoodland @smsm1 @revk @aaisp my phone is dual SIM so I have Giffgaff as the personal primary SIM but sip2sim as the second so it's connected to my home PBX.

So, until I got redundant, I gave the VoIP numbers to work when I was on support, one UK & one US & not my personal number.

This is why I like this sort of service, & it separates personal calls from "work" easily.

peter,
@peter@area51.social avatar

@saxicola @awoodland @smsm1 @revk @aaisp that works when you have WiFi.

That said no reason why that works, but for me this works to keep professional mobile away from personal.

Over 10; years ago I had an issue where a book maker got hold of my personal number and I got calls from them at 2am whenever we had maintenance.

That was the point when I separated work from home calls when giving alternative numbers

I got a new router to replace our aging one, which just can’t handle the amount of traffic we sometimes have these days… but god, I do not want to have to port my existing network setup over. 😫

peter,
@peter@area51.social avatar

@gregly It might be intimidating the first time you do it but it's not that bad in reality - although I've been doing this sort of network thing for 30 odd years.

Main bits are:

Each internal router set on it's own IPv4 network, but the WAN port connects to the edge router so it has an IP on that network and set it's default route to the edge router's IP.

On the edge router, add a default route for the new subnet pointing to the internal routers IP on the edge network.

1/2

peter,
@peter@area51.social avatar

@gregly My home network is a bit complex as I have multiple internal routers, one for the office and one just for WiFi - with the edge router connecting them to common core servers and the net.

I've also got it so each network has it's own IPv6 /64 network as well as IPv4

2/2

peter,
@peter@area51.social avatar

@gregly Ah, if it's in dumb mode then it's just acting as a modem to their network.

So in theory you would just set up your new router as if you were connecting it to them directly and it it's WAN IP would be the one they present to it.

peter,
@peter@area51.social avatar

@gregly So for the extra router you have, you'd set it up like I said but the "edge" router is your one not the ISP one

I’ve got a fat pipe (ffnar) to the house, so I figure I should really save my cash, stop self hosting everything on remote VPS’s, and get myself a little Linux machine with a load of disc space that can sit in my office.

So I bought a Firebat T8 off Ali Express. N100. 16G Ram. 512G disc.

IT IS FUCKING TIIIIINY

peter,
@peter@area51.social avatar

@stevelord @k I've got a couple of ryzen based machines of a similar size with a similar intention on moving stuff off remote severs that don't need to be external.

ProxMox runs really well on them.

32G ram not 16G and I did swap out the nvme on them.

I'm going to be interviewed live on German radio station Radio Eins in a bit (around 11:20 my time today, I was told). You can tune in if you are in the Berlin area, or via the internet. My nerves! https://www.radioeins.de

@janbeta I know how you feel. I've done Radio twice in the past and felt similar once it was over

Even though I'm currently unemployed, & I stopped bidding on hardware, I just had to on this one.

I'd see it arrives but it was the one machine on my bucket list for almost 40 years.

I won't say what it is until I get it, but fsck, hopefully I've finally got one!

To me this one is the holy grail, enough said

peter,
@peter@area51.social avatar

@RichieRich yeah that would eclipse this 😮

I'll not say what it is until I have my hands on it, but it's the machine I've always wanted

Hmm, the BBC getting basic temporal mechanics wrong again...

"just before 16:00 local time (07:00BST; 08:00GMT)"

According to an article BST is UTC-1 now?

peter,

@ukscone The unicorn's are good, I've got one of those mounted on my home office wall as a clock/weather display.

Should revisit it as I've still not got it supporting summer time so it's stuck on UTC

peter,
@peter@area51.social avatar

@ukscone I need to find what I did with the source for this one, but it's based on the examples for it.

NTP to sync the time once an hour

MQTT to get the weather from the station

Ability to send a short message via MQTT so it will display a scrolling message
