Has a Sudoku with 16 clues finally been discovered? How good are you at Sudoku?
It is supposed to be impossible for a "Sudoku" with 16 clues to have a unique solution. Try to solve the Sudoku below before you look here:

The “Sudoku” below has 16 clues and two solutions. However the two solutions appear to only swap around the 8s and 9s. Since there are no 8s or 9s in the original puzzle does this mean the solution is unique?
It is believed that there is no Sudoku with 16 clues i.e. with a unique solution. It was mathematically proven in 2012 by Gary McGuire and his team that 17 is the minimum number of clues possible for a valid Sudoku puzzle to have a unique solution; puzzles with 16 or fewer clues cannot have only one solution.

Poll: 🤖 What skills do you think give a CV the ultimate edge in a robot-filled workplace?
The Reserve Bank has shared some pretty blunt advice: there’s no such thing as a “safe” job anymore 🛟😑
Robots are stepping into repetitive roles in factories, plants and warehouses. AI is taking care of the admin tasks that once filled many mid-level office jobs.
We want to know: As the world evolves, what skills do you think give a CV the ultimate edge in a robot-filled workplace?

Poll: Should complete designs be shared with the public, or should the community help shape the designs from the start?
The Post recently shared an opinion piece on the Harbour Crossing and why a more democratic approach might be needed 🚗🚲👟
While most decisions sit within the political arena, many organisations—like NZTA—manage long-term projects that go beyond party lines. Politics can sometimes disrupt progress, and the next Harbour Crossing is a big decision that will affect all Aucklanders.
We’d love your thoughts: Should near-complete, shovel-ready designs be shared with the public, or should the community have a hand in shaping the designs from the start?

Even Australians get it - so why not Kiwis???
“Ten years ago, if a heatwave as intense as last week’s record-breaker had hit the east coast, Australia’s power supply may well have buckled. But this time, the system largely operated as we needed, despite some outages.
On Australia’s main grid last quarter, renewables and energy storage contributed more than 50% of supplied electricity for the first time, while wholesale power prices were more than 40% lower than a year earlier.
[…] shifting demand from gas and coal for power and petrol for cars is likely to deliver significantly lower energy bills for households.
Last quarter, wind generation was up almost 30%, grid solar 15% and grid-scale batteries almost tripled their output. Gas generation fell 27% to its lowest level for a quarter century, while coal fell 4.6% to its lowest quarterly level ever.
Gas has long been the most expensive way to produce power. Gas peaking plants tend to fire up only when supply struggles to meet demand and power prices soar. Less demand for gas has flowed through to lower wholesale prices.”

If even Australians see the benefit of solar - then why is NZ actively boycotting solar uptake? The increased line rental for electricity was done to make solar less competitive and prevent cost per kWh to rise even more than it did - and electricity costs are expected to rise even more. Especially as National favours gas - which is the most expensive form of generating electricity. Which in turn will accelerate Climate Change, as if New Zealand didn’t have enough problems with droughts, floods, slips, etc. already.
