Hard Numbers: The Packed Democratic Presidential Calendar

30 million: When police arrived at the home of Peru's former President Alan Garcia on Wednesday to arrest him on bribery charges, he killed himself. Brazilian construction firm Odebrecht, focal point of the enormous, multi-country Lava Jato corruption investigation, has admitted to paying $30 million of bribes in Peru since 2004. All of Peru's living ex-presidents are either in jail or under investigation for corruption.

20 billion: The EU this week threatened tariffs on $20 billion of US goods ranging from ornamental fish to exercise equipment as part of a long-running dispute over aerospace subsidies at the World Trade Organization. Washington recently listed $11 billion of European items that could be subject to new levies. Upcoming US-EU trade talks should be fun.

1,800: China granted permanent residency to just 1,800 foreigners in 2017, the latest year for which data is available, compared to about 1 million "green cards" given by the US to immigrants each year. Relative to its size, China is home to fewer foreigners than almost any other country in the world.

64: It may not take long for Democrats to find their 2020 presidential nominee. Under the current schedule, 64 percent of pledged delegates to the Democratic Party's national convention will be awarded in the first seven weeks of primary elections and caucuses, from February 3 to March 17, 2020. That percentage will increase if Colorado, Georgia, and New York—three large states that have not yet set a date for their votes—land during that period.

Ferrera Erbognone, a small town in the northern Italian province of Pavia, is home to one of the most cutting-edge computing centers in the world: Eni's Green Data Center. All of the geophysical and seismic prospecting data Eni produces from all over the world ends up here. Now, the Green Data Center is welcoming a new supercomputing system: HPC5, an advanced version of the already powerful HPC4. Due to be completed by early 2020, HPC5 will triple the Green Data Center's computing power, from 18.6 to 52 petaflops, equivalent to 52 million billion mathematical operations per second.

A few days ago, the New York Times published a bombshell report on the Chinese government's systematic oppression of Muslims in Western China. The story was about many things: human rights, geopolitics, Chinese society – but it was also about technology: Beijing's repression in Xinjiang province is powered in part by facial recognition, big data, and other advanced technologies.

It's a concrete example of a broader trend in global politics: technology is a double-edged sword with sharp political consequences. Artificial intelligence, for example, can help develop new medicines but it can also support surveillance states. Social media helps nourish democracy movements and entertains us with cat memes, but it also feeds ISIS and 4Chan.

Increasingly violent anti-government protests in Hong Kong have dealt a major blow to the city's once booming economy. Tourism – an economic lifeline in that city – has dropped, and retailers are suffering from a sharp decline in sales. Now, six months since the unrest began, Hong Kong has recorded its first recession in a decade, meaning its economy has contracted for two consecutive quarters. Here's a look at how Hong Kong's quarterly gross domestic product (GDP) growth has fared during the past two years.

Tehran's Next Move: "We don't want an Islamic Republic, we don't want it," was the chant heard among some protesters in Tehran over the weekend after the government announced a 50 percent fuel price hike meant to fund broader support for the country's poor. Under crippling US sanctions, the country's economy has plummeted, unleashing a "tsunami" of unemployment. What started Friday as nationwide economic protests took on a political coloring, as protestors in some cities tore up the flag and chanted "down with [Supreme Leader] Khamenei!". The unrest seems to be related, at least indirectly, to widespread demonstrations against Tehran-backed regimes in Iraq and Lebanon as well. Economically-motivated protests erupt in Iran every few years, but they tend to subside within weeks under harsh government crackdowns. So far, the authorities have shut down the internet to prevent protestors from using social media to organize rallies. But Iran's powerful Revolutionary Guards Corps has warned of more "decisive action" if the unrest continues.
