The BBC micro was a ridiculously good hobbyist / tinkering machine ever created. It had a bunch of easy to use interfaces both digital and analog. It had great upgrade potential with interfaces for sideways roms and even a second processor. It also had a extremely fast Basic interpreter. The only thing that really limited it was the 64k memory limit due to the 16 bit addressing of the 6502 processor.
Acorn MOS allowed an extra 16 banks of sidways RAM, so you could get up to 256KB extra RAM, but you would need to buy an extra board.
The B+ models (64/128KB) also had an extra 32KB of Shadow RAM, 20KB of which shadowed the address space used for video and the other 12KB was for the MOS.
So a theoretically maxed out Beeb would have 32+32+256=320KB of RAM.
The cool thing about Sideways RAM is that you could use it for data, code, or to load ROM images which would work as normal ROMs.
"when my mobile net has run out"? Are Japanese mobile networks stuck in the 2010s? In Europe unlimited (or at as near as makes no difference) data has become so ubiquitous that public wifi is more or less redundant.
Taking a brief look at Airalo, it looks like it'd cost me $4-5 per gigabyte to buy an eSIM. I literally see no unlimited options on Amazon.
Randomly navigating to telekom.de, I see a front page offer of €34.95 monthly for a five gigabyte plan with a 24 month contract term.
orange.fr seems to do a little better with a €16.99 plan for 100 GB but it seems to be a promo rate and also requires an activation fee and a bank account statement, making it useless for tourists. Still, $5 is a lot cheaper than €16.99 even if you could get that rate. For €5 prepaid you get, I shit you not, 20 megabytes of data from Orange. https://boutique.orange.fr/vitrine/rechargements-mobile/mobi...
Prepay is generally a better deal in UK and Ireland and often includes unlimited internet for about €20. Here is an example from Vodafone (not the cheapest by any means): https://n.vodafone.ie/shop/pay-as-you-go-plans.html €25 per month gets you unlimited data in Ireland and up to 30Gb in other EU countries including Germany.
I have always thought it a bit odd that users with a monthly contract often pay more than "pay as you go pre-pay" but I think that is because it is mainly business and older people who opt for a monthly contract.
Did you really point out a plan that has sharply limited data in the EU as some sort of support for your original statement that nobody worries about data in the EU??
Wow 20MB isn’t even enough to open Google maps, find a restaurant and navigate to its menu.
Unlimited plans usually throttle you these days too. I have €60 “unlimited” from orange.lu and after 250GB it throttles to 250kbps. At this speed hacker news is usable but not much else is. It’s €20 to add another 100GB. While waiting months for home internet to be installed I tethered to this and between WFH, gaming and streaming I usually had to top up 1-2 times per month.
So I bought a 16GB 6-month tourist sim, and somehow run it out, probably by drunkenly making video calls / using YouTube without realising I wasn't connected to wifi.
I think there are unlimited or huge (30GB/month) sims available for non-tourists. A lot of households use 4G as their main internet source via a dongle!
I have 60GB a month on my phone, at home we recently switched from a wired 2Gb/unlimited connection to a 5g/unlimited connection. (This is in Japan btw).
The dongles have weekly limits too, I think. I remember staying in an AirBnB that came with a 4G dongle for the guest, but the week's quota had been spent by the previous guest.
Can someone explain to a clueless person (me) how a 1Hz CPU manages to achieve even 0.1fps frame rates. That is only ten clock cycles per frame. I don't know what the IPC of Chungus 2 is but that doesn't seem a lot of cycles to calculate each new frame.
Thinking about this another way. Real world CPUs have clock speeds at least 1 billion times faster than this and they only run Minecraft a few 1000 times faster than is claimed here. How do these numbers add up?
The video author (Sammyuri) clarified it in a comment:
> This build does NOT run in real time. It runs on MCHPRS, the server developed by StackDoubleFlow, which speeds up the game roughly 10-20,000x while running redstone. That brings the framerate to a much more reasonable 0.1fps, so the long timelapses in the video only took 9 hours to record in total.
Can anyone give me a TLDR of this? I think it is saying that "Just cause cats don't act like humans doesn't mean they aren't smart" but its very long and doesn't have a decent summary so I am not sure.
This annoys me because it is the opposite of the way I do matrix multiplication myself. I work from left to right taking the rows of the left hand matrix, transposing them then scalar producting them with each column of the left hand matrix in turn. This animation starts with he columns of the left hand matrix and it feels like it is "working backwards" by going from right to left.
I can bring you back a little further than BBS system. I was in University n Europe in the 1980s and thanks to IBM European Universities got free access to a European academic research network (EARN). We soon discovered that you could use various gateways to get stuff off the much more developed US academic / defense research network called internet called ARPANET. The most reliable way of communicating was to use specially constructed emails and the servers would send files back in ASCII encoded pieces also by email that you had to reconstruct to get the original files. It always amused me that the biggest server around was hosted by "White Sands Missile Base" and I
downloaded a lot of stuff from there.
It is worth noting that back in those days you couldn't just type an email as John@company.com. You needed to tell the mail server what path it needed to take to get to the recipient. We developed quite ingenuous ways of bouncing emails around various connected networks in order to get them to our intended destinations.
The mailing system your are referring to is called UUCP (Unix to Unix copy protocol). It can use serial link or IP as a transport to transmit batches of tar-gzipped emails. Binaries were usually uuencoded in mail body (if you are on FreeBSD, type: man uuencode).
If you have any interest in the origins of the personal computer you should track down the sublime documentary series "Triumph of the Nerds" by Bob Cringely. You an find various versions on Youtube.
Wait a sec. I can rent a whole car for less than €8.50 per hour. I sure as heck am not going to pay an extra €8.50 an hour for a car I already bought and paid for.
