- Comment on Howto build 8-bit breadboard computer 1 week ago:
Here it is.
Top breadboard is solely for the decimal display. It has a timer to refresh the display and an eeprom with a lookup table to turn the binary inputs into outputs that show the decimal on the display.Bottom is input dip switches and a register - value from 0 to 255 (and selecting if negating).
Blue dial, lonely red led and red button is the clock/reset.
The Green and Yellow combo is interesting - it loads the value you set through an xor gate (to do negating, under clock) into the adders (next to green leds). The output from the adders is displayed on the green leds, and copied to the register for the yellow ones. The yellow register is then tied to the other input of the adders, so on each clock cycle it loads the previous value and continually counts up (or down) in the number you selected.
The display is tied to the yellow leds for convenience (it was easier than trying to get to the green ones.
It’s a nice little desk display!

This is an amazing series for understanding how you can make some sand ‘think’. It’s not just about putting it together - it’s his way of explaining why and how things work that makes it an incredible watch.
I built a modified ALU desk display from watching this - you use dip switches to set the value (between 0 and 255) and it will the count up in that number, displaying the decimal result in a 7 segment display (and binary as leds). It can count down too!

- Comment on School Monitoring Software Sacrifices Student Privacy for Unproven Promises of Safety. 2 months ago:
There’s other ways - write it into the conditions of loan that it’s not the school’s responsibility to monitor student use when at home.
There are solutions that allow monitoring only on campus - both the monitoring person and the student need to be on-site for the software to contact a licensing server. No server contact=no monitoring.
And never bring ‘AI’ into it. - Comment on School Monitoring Software Sacrifices Student Privacy for Unproven Promises of Safety. 2 months ago:
OK so that’s nuts they installed a private ‘AI’ monitoring software that they have no oversight or control over. From the article, they can’t even see what it flags as inappropriate - it just flags and deletes.
A school admin should never hand over that much control! - Comment on Australia records hottest ever winter temperature with some areas set to be 10C above average 2 months ago:

That’s really interesting!
I just discovered a theory about the cause of the ‘late heavy bombardment’, which is thought to have delivered water to earth via comets.Essentially the gas giants all orbited much closer, but Jupiter and Saturn got into resonance and flung Uranus and Neptune way out (and Saturn too). Uranus and Neptune flew out into the path of a heap of ice, and their gravity pulled the ice into an orbit that collided with the terrestrial planets.
- Comment on Size Comparison: Pluto and Australia 3 months ago:
Jupiter does throw its weight around a bit too much.
- Comment on Size Comparison: Pluto and Australia 3 months ago:
Do you mean the Trojans? They’re excluded from the mass calculation of ‘clearing the neighbourhood’ because they’re in a resonant orbit - their orbit is a consequence of Jupiter’s mass.
- Comment on Size Comparison: Pluto and Australia 3 months ago:
Absolute size isn’t really in the criteria for a planet though. Pluto isn’t a planet because it shares its orbit with lots of other icy bodies in the Kuiper belt.

- Comment on X’s Premium users can no longer hide their blue checks 7 months ago:
Iirc just recently they started giving out blue ticks to people with lots of followers, regardless of if they wanted it. Then this week they make it so you can’t hide them. It seems like a dim move - piss off the people who bring lots of traffic to your website, but actively decided to not get a blue tick, by forcing the tick on them.
If they didn’t leave beforehand, maybe this would make some people/orgs consider leaving? - Comment on Wi-Fi jamming to knock out cameras suspected in nine Minnesota burglaries -- smart security systems vulnerable as tech becomes cheaper and easier to acquire 9 months ago:
A lot of the new systems can use battery powered cameras that are motion activated - they can last for a month+ on battery because they only turn fully on when they detect motion.
You’re right though - if it’s mission critical don’t rely on wireless.

- Comment on Expensive school uniforms don't make kids better at maths, so why are schools so focused on them? 9 months ago:
On the other hand, an argument for uniforms would be that they remove a whole raft of problems with grey areas.
Without a uniform, you’d need to have a policy about ‘acceptable’ clothing - profanity, slogans, sun safety, workplace safety etc which would all be up to interpretation by students and an administration.
And you know that students would push the boundaries, and the ‘line’ would be constantly redrawn every week.
How short is too short on sleeves? What words are inappropriate on shirts?Uniforms remove this - you’re either in the approved uniform, or you aren’t.

To add to this, when the trademark lapsed in the 90s, Burger King America actually opened BK branded stores here in an attempt to push out the Australian franchise holder (hungry jacks).
BK lost the legal case, had to pay a heap of money and decided to leave Australia, transferring all the bk stores to Hungry jacks. - Comment on Google CEO Sundar Pichai Warns Android Users Not to Sideload Apps 11 months ago:

- Comment on Referendum Results, Congratulations, Comiserations 1 year ago:
Something I’d read/listened to recently suggested that it might have more of a detrimental affect on Dutton when it comes to the election - people will remember his campaigning during this, and be really turned off it when voting for a leader. On the other hand, Albanese has done some work towards keeping his leadership separate from the outcome of the result.
