An encryption system for recording votes without the voters' name is valid in principle. However, for other reasons, it isn't ready for real use in official elections.

It is designed for use in voting machines in a polling place. It would not be safe to use this from the voter's own computer over the internet.

Artists in Brazil are already facing persecution and violence from the religious fanatics that voted for Bolsonaro. Some have already fled the country. Others are trying to resist.

Once Bolsonaro and his allies start mobilizing violence, I fear that many artists will be killed soon. If all he does is eliminate subsidies and tax deductions, that will be quite a relief.

Several of the artists mentioned do conceptual art. I generally find conceptual art uninteresting, because words can express concepts more clearly than ad-hoc symbols. Rather than watch the conceptual art and wonder what the point was, I'd say, "If you write it down in a few lines, I'll read them."

Hundreds of thousands of Americans participated in protests to defend Mueller's investigation of the bully's apparent collaboration with Russia.

I don't know whether protests can achieve anything against the shameless dishonesty of Republicans. Protests won't dissuade the bully -- he would love to imprison every protester and boast of how powerful he is. A year ago, some Republican officials said that they wanted to defend the investigation. Do they care any more?

The town of Paradise, California, was completely destroyed by a wildfire. It sprang up and engulfed the town in less than one day.

Does anyone know whether trees in that region have been killed by pests whose range has extended due to global heating?

Meanwhile, some rich people's mansions were burned in Malibu. I hope this teaches them to support efforts to curb global heating.

The UK is moving families with no domicile from London to faraway cities to house them. They get a place to live, but don't know anyone, and may have little chance of being anything but isolated in their new homes.

However, this is not as bad as some countries. In the US, these people would be dumped on the street.
