My Founders Edition arrived today complete with T-shirts and a flag! Actually looks a lot smarter than expected and the keyboard definitely feels better than the Starlight. Whether by design or luck the power switch isn’t as stiff either. #Commodore64Ultimate #FoundersEdition

@tandemar I'm not entirely sure Keiren knows how to cut and paste, I think he types it out 2 fingers at a time....

So which version did your older sister buy then Kieren? Spectrum, MSX or Amiga? Or did she buy all three? Because surely you're not just cutting and pasting content? #kierenhawken

This is a great demo. The know-it-all contrarian replies make me cringe. Here’s a quick explainer what’s going on AND why it’s much worse than it appears. Copper Clad Aluminum (CCA) cables are copper cables with aluminum cores. They exist purely for the ~25% cost reduction. They almost always have cost-cutting insulation. Let’s touch on both topics, then combine into a unified nightmare :) CCA vs solid copper: CCA has lots of negatives. The primary in this context is that it has ~60% more electrical resistance. This degrades high speed signals(2.5G/5G/10G), especially as you get near the limits of length. It also significantly increases how much the cable heat up. Let’s say you are doing PoE++ at 100W, across 100 meters, on a tiny 24 bundle pair. The CCA will produce ~150W of additional heat. Thats a small space heater! But it’s not evenly spread across the cable because… CCA is also brittle, so any partial hairline cracks will become concentrated hot spots. CCA also doesn’t “bite” well when terminating, which creates another opportunity for hot spots. Worse: this gets worse over time due to aluminum oxidation. And then we get to the insulation. Flame retardant and stiffeners cost money, so they are left out. That means you have insulation that gets very soft under much lower temperatures on a metal that gets much warmer. That the metal starts to squeeze together which will mess with the data signal, or worst case, allowing the start of a short (another hot spot). Keep in mind, these cables are often run in bundles (compounding the heat) and through hot locations like attics. And if the insulation ever catches fire, it does NOT self extinguish. Yes, the cable itself could ignite, but ANYTHING starts a fire, you effectively have a fuse inside your walls now. That’s exactly what @TracketPacer is showing in this video. Lots of commercial buildings have “fire walls” that stop the spread of fire between sections of the building. One of the few things allowed to pass through these fire walls is… data cables! So to save 25% on your cabling, you are accepting a big degradation in data performance which will often lead to lots of debugging. It drops the voltage for PoE equipment… more debugging! Anytime the bundles are disturbed in any way… good chance of more debugging! And then you have the fire safety hazard and code violations that can leave you holding the bag for the consequences instead of the insurance. STOP BUYING CHEAP CABLES!

don’t use CCA cables

It's odd that the "Thatcher is evil because she destroyed industrial jobs in Northern England" people seem to be very very quiet about Miliband and Labour doing *exactly the same thing* to Britain's oil and gas industry, steel industry, petrochemicals industry, farming, pottery industry, hospitality industry... basically any industry that uses electricity.

Wasn’t sure if everyone knew this but: -a person can like EVs and gas cars. -a person can like EVs and not care if others get one or not. -a person can like EVs and not care about the environment. -a person can like Tesla and other EV brands. -a person can question something and still like it. -a person can cheer for something and know it has flaws. -a person can like people who like different things. 💕

@RDKLInc If you think about what they did with what they had 40+ years ago, the entire machine (64) is incredible. As you said, the SID especially so...

@CommodoreLad And PAL vs NTSC adds to the sound differences as well. SID is really a remarkable chip

Take your card number and starting from the second-to-last digit, double every second digit moving left. If doubling a digit produces a number greater than nine, subtract nine from the result. Then add all the digits together, the doubled ones and the untouched ones. If the total is divisible by ten, the number is valid. If it isn’t, the number is mathematically impossible as a card number and the form rejects it on the spot. This is the Luhn algorithm written in 1954 by a computer scientist at IBM named Hans Peter Luhn. It still runs inside every payment form on the internet today. And it turns out that valid card numbers are not random. They follow this mathematical rule, and any number that breaks it is immediately disqualified without ever touching a bank’s systems. No server contacted. No database checked. No network request made. The validation happens entirely on your device, in milliseconds. The first six digits do additional work before the Luhn check even runs. They are called the Issuer Identification Number; the first digit identifies the card network (4 means Visa, 5 means Mastercard, 3 means Amex), and the following digits identify the specific bank that issued the card. This is why payment forms show you the Visa or Mastercard logo the moment you type the first digit. No server needed. The network is encoded in the number itself. The last digit of every card number is called the check digit it exists for no other purpose than to make the entire number pass the Luhn algorithm. When a bank generates a new card number, it calculates what the last digit must be to make the sequence valid, then stamps it on the card. It is a built-in mathematical fingerprint.
Gracia@straceX

As a developer, have you ever wondered: You type a 16‑digit card number and the form instantly says “Invalid card number”. There are billions of possible numbers. How the hell is that check that fast?

The C64 actually had a higher speed interface designed at it's inception. However, somewhere in the process of laying out the PCB, the 2 lines that would have controlled this were missed off. This wasn't spotted ubtil they made a feck ton of PCBs without the lines. Commodore beinf very "economical" decided to hack the kernal until it was slow enough to cope with the serial bus they had. Only what I've read.. But, I believe its true. I think the 1540 with a VIC 20 is faster....

@CheekyC64Gamer @AnnatarTheMaia Yeah, except the standard loading routine on the 1541s / C74 kernal was awful. I mean really awful. So loading anything game size still took ages. Not C2N ages, but, ages....

Bit of C64 truth… 🇬🇧 UK = tapes 📼 ⏳ Long loads, rewinds, praying it didn’t crash 😅 🇺🇸 US = disk drives 💾 ⚡ Loading in seconds Same machine… totally different experience 🕹️ (And yeah… some had cartridges 😏🎮) #C64 #Commodore64 #RetroGaming

@CommodoreLad Very cool! You should post some pics! I collect glitch machines that I use as filters for photography, I've got probably 200 at this point between broken screens and GPU defects. I don't have much on the vintage side though cuz they tend to be lower-res
