That discussion of representations of negative numbers in binary in computers reminded me of the following. It's from HAKMEM, a compilation of computer and mathematical hacks compiled by the MIT AI Lab circa 1972; the specific item was written by Bill Gosper, emphasis mine:

Item 154: The myth that any given programming language is machine independent is easily exploded by computing the sum of powers of 2. If the result loops with period = 1 with sign +, you are on a sign-magnitude machine. If the result loops with period = 1 at -1, you are on a twos-complement machine. If the result loops with period greater than 1, including the beginning, you are on a ones-complement machine. If the result loops with period greater than 1, not including the beginning, your machine isn't binary — the pattern should tell you the base. If you run out of memory, you are on a string or bignum system. If arithmetic overflow is a fatal error, some fascist pig with a read-only mind is trying to enforce machine independence. But the very ability to trap overflow is machine dependent. By this strategy, consider the universe, or, more precisely, algebra: Let X = the sum of many powers of 2 = ...111111 (base 2). Now add X to itself: X + X = ...111110. Thus, 2X = X - 1, so X = -1. Therefore algebra is run on a machine (the universe) that is two's-complement.

Plan Ready to Launch Substantial Talent for Rugby World Cup 2023

With a new planned plan ready to launch, substantial talent within the organization, and an Executive Board that has determined goals for the next few years, it is set to be an essential period in the development of the sport. I am also well conscious of the tests that we face as we arise from the global COVID-19 epidemic and seek to get rugby back on the arena in many parts of the world.

Employed with our members and partners, we will continue with our assignment to grow the global rugby family, while advancing welfare and injury prevention for players at all levels. Enticing and engaging new spectators and delivering convincing and competitive international tournaments leftovers at the centre of our plan, along with investing in contribution growth with our member unions and local associations.

All of the Fires in Australia's Most Populous State Are 'Now Contained,' Authorities Say

All of the Fires in Australia's Most Populous State Are 'Now Contained,' Authorities Say

It has been called Australia’s “black summer”—nearly six months of devastating bushfires that raged across the country, burning through more than 11 million hectares of land, causing the deaths of at least 33 people, and killing an estimated one billion animals. But on Thursday, fire officials took to Twitter with some good news: After days of heavy rain, all of the fires burning in New South Wales, Australia’s most populous state, are now under control.

“After what’s been a truly devastating fire season for both firefighters and residents who suffered through so much this season, all fires are now contained in New South Wales,” said NSW Rural Fire Service Deputy Commissioner Rob Rogers in the video update. “[W]hich is great news.”

Some fires continue to burn in the southern part of the state, Rogers noted, but are classified as contained.

New South Wales has been particularly hard-hit by the conflagrations. Two blazes alone, the Currowan and Gospers Mountain fires, each tore through some 500,000 hectares of land there, according to BBC News. Heavy downpours that began last week helped stamp out the Currowan fire, as well as the Lindfield Park Road fire, which had burned for 210 days.

The rains marked a shift from a prolonged drought that has afflicted Australia for the past three years. Parched conditions made it easier for fires to spread—and more difficult to extinguish them.

“[B]ecause it was so dry, you could be getting 50 millimeters [of rainfall] and that rain would just be absorbed very quickly,” Simon Heemstra of the Rural Fire Service tells BBC News. “And within a couple of days that vegetation had dried out again and started burning again.”

But the recent downpours were torrential, with some parts of the country experiencing more than 400 millimeters of rain. The deluge not only tempered bushfires in New South Wales, but also filled dams that had plummeted during months of dry weather. According to NPR’s Bill Chappell, water storage for the greater Sydney area has hit 75.1 percent, up 33.4 percent since last Thursday.

The rains have, however, been a mixed blessing. Last week, the New South Wales Bureau of Meteorology warned of “very dangerous conditions” caused by torrential rains, high winds, waves and tides. Over the course of 24 hours, the NSW State Emergency Service received around 2,500 calls for help because of the deluge, reports NPR. According to BBC News, flash floods in the state of Queensland led to the death of one person. Residents have also been dealing with power outages and flooded roads.

Then there is the matter of the forces driving Australia’s extreme weather. Wildfires have long been a part of Australia’s natural history, but experts say the country’s fire season has become longer and more extreme due to climate change. Heavy rains have been linked to climate change, too. A 2017 report by the Australian Bureau of Meteorology, for instance, found that “climate variability can profoundly change rainfall patterns and intensity over the Pacific Ocean from year to year,” making both droughts and flooding more likely.

But for flame-weary Australians, the abatement of months of fires still comes as a relief.

Now that the flames have subsided in New South Wales, said Rogers in the video, “We can really focus on helping people rebuild.”

An Australian community is rallying around a widower and his six children who recently lost everything in the devastating bushfires, just a month after the man’s wife died of cancer.

Back in October, Bill Morris faced the unimaginable when he lost “the love of his life” Elaine Morris to cancer, according to family friend Kylie Kinnish, who set up a GoFundMe page for the Morrises.

As they were working through their grief, things only got worse for the tight-knit family when fires ravaged their community a month later and destroyed their home, leaving Bill and his six children with next to nothing.

“The out of control bushfires have destroyed the home they had built together over the past 30 years at Upper Colo,” Kinnish wrote on the GoFundMe. “They raised their 6 beautiful children in this home and sadly not only are they now grieving the loss of their mother but the loss of all that was hers.”

Kinnish, whose mother was best friends with Elaine, posted a number of heartbreaking photos on GoFundMe, showing what was left of Morris family’s property and asked their loved ones for help in rebuilding their home.

Some of the photos that were posted showed piles of charred rubble and debris alongside the home’s folded structure. Other heartbreaking images captured the damage from the flames to the interior of the home and household appliances.

“The grief they are suffering after Elaine’s passing 3 weeks ago is heartbreaking,” Kinnish wrote on Nov. 16, one day after the fires came through. “And now today the Morris family are heading out to see the property for the first time since the fires… As you can imagine this will be another heartbreaking step for them to take.”

That same day, one of Bill and Elaine’s daughters Georgia posted an update to her Facebook, which was also shared on the GoFundMe page.

In the post, Georgia revealed that her family was struggling to accept the loss of their mother and their home, but that their farm animals had luckily survived the blaze. She also shared a number of photos from the devastation, including one of the chickens on their property.

“Today was the first day that we returned to our childhood home after it was burnt down in the Gospers Mountain bushfire on Friday afternoon,” she wrote. “You can’t even put a word to how we are all feeling, devastated doesn’t even come close.”

“As you can see by the photos, we have lost everything- More so Dad and Billy who had every single belonging burnt in the fire,” she went on, referencing her brother. “We are lucky that our family is so close-knit and we have each other to lean on for support.”

Georgia went on to thank everyone who donated to help her family and to the Rural Fire Service volunteers for “trying to save our home” and for risking their lives each day to protect Australians from the deadly blaze.

“We are glad no one was injured trying to save our property,” she added. “I am also happy to report that EVERY SINGLE CHICKEN SURVIVED!”

Since its creation on Nov. 15, the GoFundMe campaign has raised over $62,000.

An update on Dec. 20 by Kinnish said that Bill and his children “are still coming to terms with the loss of both Elaine & their family home,” but that the money from this fundraiser will help “keep things as simple as possible for them so they can grieve without stress.”

“All funds raised through this page will be withdrawn by myself & transferred directly to an account Bill has set up for the rebuild,” Kinnish added. “We wish to thank each & every one of you for your generous donations so far. We will keep this page updated as the build progresses once we can access the property in the new year.”

The Morrises are part of the thousands of people who have been displaced and lost everything in the devastating fires.

Since September, at least 25 people have been killed while a whopping 11-million acres have been wiped out with hundreds of homes and buildings destroyed, as well. A seven-day state of emergency was declared on Dec. 23.

As the more than 130 fires continue to burn across New South Wales and Victoria, ecologists from the University of Sydney believe almost half a billion animals have died.

As of Thursday, there were 2,000 firefighters working in New South Wales alone, with additional help arriving from the United States, Canada, and New Zealand.
