From an app to diagnose disease on Zambian farms to Tinder-style matchmaking for Senegalese land owners and young farmers, young coders have been finding solutions to hunger in the first Africa-wide hackathon on the issue.

Eight teams competed in the hackathon, organized by the U.N. Food and Agriculture Organization (FAO) and a Rwandan trade organization this week in the country’s capital Kigali.

Experts say keeping young people in farming is key to alleviating hunger in Africa, which has 65 percent of the world’s uncultivated arable land, but spends $35 billion a year on importing food for its growing population.

“In our families, agriculture is no longer a good business. They don’t get the return,” said Rwandan Ndayisaba Wilson, 24, whose team proposed a $400 solar-powered device that can optimize water and fertilizer use.

“We believe that if the technology is good and farmers can see the benefits, they will adopt it.”

Among the proposed solutions were an app that links aspiring farmers with land owners in Senegal and a Nigerian mobile platform that uses blockchain to help farmers demonstrate their creditworthiness to lenders.

The winner was AgriPredict, an app already operating in Zambia that can help farmers identify diseases and pests. Those pests include the voracious fall armyworm, which eats crops and has wreaked havoc in much of sub-Saharan Africa.

Farmers can access the app directly from their phones or via Facebook. CEO Mwila Kangwa, 31, said the initiative came out of the twin disasters that hit Zambian farmers in 2016: the fall armyworm and Tuta absoluta, the pest commonly known as the tomato leaf miner.

“We noticed there were no tools whatsoever that will help farmers mitigate or prevent or even counter these diseases so we came up with this idea of creating a software to help farmers,” he told the Thomson Reuters Foundation.

As winners, the Zambian team will receive coaching from the FAO to refine their product and an opportunity to meet potential funders and partners.

“What they brought was a technically sound solution … and the ability to convey the message to young people by using, for example, Facebook,” said Henry van Burgsteden, IT officer for digital innovation at the FAO and one of the judges.

The hackathon was held during a conference in Kigali on ways to attract more young people to agriculture through information and communication technology tools.

High unemployment and the challenges of rural life mean many young people desert farming for the city, while aging farmers struggle with climate change, poverty and poor infrastructure.

A federal judge hearing arguments over a settlement between the Trump administration and a company that wants to post plans for printing 3D weapons on the internet said Tuesday that the issue is best decided by the president or the Congress.

U.S. District Judge Robert Lasnik that while he will still rule on the legal issues involving the settlement, “a solution to the greater problem is so much better suited” to the president or Congress.

The settlement prompted 19 states and Washington, D.C., to sue the Trump administration for allowing a Texas company to distribute instructions on how to make printable three-dimensional guns.

Lasnik issued a temporary restraining order blocking the online release of the blueprints. Now, the states and Washington are seeking a permanent ban.

A lawyer for the U.S. Justice Department argued that it is already illegal to possess plastic guns, and the government is fully committed to enforcing that law.

But Lasnik questioned the logic behind enforcing a ban on undetectable guns rather than proactively stopping them from being made in the first place.

It is unclear when he will issue his final ruling in the case.

U.S. President Donald Trump said on Monday that it is “very dangerous” for social media companies like Twitter and Facebook to silence voices on their services.

Trump’s comments in an interview with Reuters come as the social media industry faces mounting scrutiny from Congress to police foreign propaganda.

Trump has made his Twitter account — with more than 53 million followers — an integral and controversial part of his presidency, using it to promote his agenda, announce policy and attack critics.

Trump previously criticized the social media industry on Aug. 18, claiming without evidence in a series of tweets that unnamed companies were “totally discriminating against Republican/Conservative voices.” In the same post, Trump said “too many voices are being destroyed, some good & some bad.”

Those tweets followed actions taken by Apple Inc., Alphabet Inc.’s YouTube and Facebook to remove some content posted by Infowars, a website run by conspiracy theorist Alex Jones. Jones’ own Twitter account was temporarily suspended on Aug. 15.

“I won’t mention names but when they take certain people off of Twitter or Facebook and they’re making that decision, that is really a dangerous thing because that could be you tomorrow,” Trump said.

Trump appeared on a show produced by Infowars, hosted by Jones, in December 2015 while campaigning for the White House. In removing Jones’ content, YouTube, Twitter and Facebook each pointed to specific user agreement violations. For example, Facebook removed several pages associated with Infowars after determining they violated policies concerning hate speech and bullying.

Twitter and Facebook declined to comment on Trump’s statement. Apple and Google did not immediately respond to a request for comment.

In July, during a House of Representatives Judiciary Committee hearing, executives from Facebook, Google and Twitter testified they did not remove content based on political reasons.

“Our purpose is to serve the conversation, not to make value judgments on personal beliefs,” Nick Pickles, Twitter’s senior strategist, said at the time.

After long resisting change, Twitter CEO Jack Dorsey wants to revamp the “core” of the service to fight rampant abuse and misinformation. But it’s not clear if changing that essence — how it rewards interactions and values popularity — would even work.

Though Dorsey was scant on details, what is certain is that the move will require huge investments for a company that doesn’t have the same resources that Google and Facebook have to throw at the problem. Any change is likely to affect how users engage with Twitter and hurt revenue, testing the patience of both users and investors.

“Social networks have a history of … well-intentioned but badly designed efforts to fix this,” said Nate Elliott, principal at marketing research firm Nineteen Insights.

Twitter isn’t alone in having to deal with hate, abuse, misinformation and bad actors using the service for elections interference, targeted harassment and scams. And Twitter isn’t alone in proposing fixes that don’t get to the heart of the problems.

Case in point: Facebook. After Russian trolls were found to have used Facebook to interfere with the 2016 U.S. elections, including by purchasing ads, the company spent a lot of time and energy building a tool that shows who’s behind political advertisements. But Elliott said it’s not even clear which ads on Facebook are the ones causing problems around foreign elections meddling. In 2016, Russian agents weren’t so much running political ads for or against candidates but rather social ads on divisive such as gun control and immigration.

But like Facebook, Twitter has to try — or at least be seen as trying.

Dorsey told The Washington Post that Twitter had not considered changing the core of the service until now. Like Facebook and others, Twitter has been accused of tinkering around the edges, tweaking policies and hiring masses of moderators when what’s really needed is a fundamental shift in how they work and how they make money in order to survive. While many former executives and other insiders have proposed radical shifts at major social networks, it’s rare for a sitting CEO to propose something as drastic as revisiting the foundation that his company is built on.

“We often turn to policy to fix a lot of these issues, but I think that is only treating surface-level symptoms that we are seeing,” Dorsey said.

Twitter confirmed Dorsey’s comments to the Post, but declined further comment.

Revamping the core could mean changing the engagement and rewards designed to keep users coming back — in the form of seeing their tweets liked, responded to and retweeted, and seeing their follower counts grow. It’s the tiny dopamine hits we get with each like that makes us feel better and keeps us returning for more. Take that away, and users might not want to return. In turn, advertisers might stay away, too, as they rely on monthly and daily user numbers, as well as user interactions, to gauge how well their ads work and how much to spend.

Unlike Facebook, Elliott said, Twitter doesn’t have billions of users to absorb any hits on user growth. Even if the changes work, he said, “it’s going to cost them so many users and so much money I can’t imagine them sticking with these kinds of changes.”

Paul Verna, an analyst with research firm eMarketer, also isn’t “terribly optimistic” that Twitter can make its service safer without hurting its business. The same goes for Facebook, and YouTube.

“Because they rely on an advertising business model, they need to not only continue to reach audiences, but try to get them to spend as much time on platforms as possible,” he said. “That creates an inherent tension between your business needs and being a good citizen.”

That said, Twitter may not have to reinvent itself completely to improve. Elliott said better policies might go a long way toward reducing the abuse. For example, it’s currently OK to harass someone on Twitter, as long as it’s not harassment based on certain categories such as gender and sexual orientation. Elliott said Twitter may just need to prohibit all harassment.

Outfielder Rolando Rodriguez from Panama heard a reporter’s question, but he doesn’t speak English. So Georgia shortstop Tai Peete helped him out, pecking the words into Google Translate to ask about how young baseball players are sharing technology during the Little League World Series.

“It was easier than expected,” Rodriguez said of the language barrier, speaking through an interpreter.

So goes life in the International Grove, the dorms where 16 teams all are staying during the double-elimination tournament in pursuit of a world title. Apps and even video games are making it easier for the boys to communicate and get to know each other — making smartphones a key part rather than a distraction during their moment of a lifetime.

Eight teams are from U.S. states while the other teams represent various countries around the world and the U.S. territory of Puerto Rico.  Players are using Translate to input questions in their native languages and let other players read or hear them in one of more than 100 languages.

Trading pins

That’s changing some of the tournament’s traditions. For example, each team has pins that they are given to trade with other teams. While body language used to go a long way in this process, players are using technology to directly ask for trades.

No words actually need to be spoken aloud, but the kids still are helping fellow baseball players pronounce the words, learning a little bit of a new language in the process.

“I talked to the Mexico team,” Peete said. “I was talking about Little League and they couldn’t pronounce it, so I was helping them.”

Even with better technology, language and cultural barriers still exist.

It’s “a lot harder than I thought,” said Lee Jae-hyeok of South Korea, who noted through a human interpreter that players also were using Facebook to connect.

The days leading up to the start of the series on Thursday consisted of practices, interviews and hanging out in the players village. For the duration of the tournament, each team from the U.S. bracket shares a dorm with one of the international teams. The rooms have bunk beds and TVs, but no Wi-Fi.

They do have a game room, however, which allows players to get their video game fix in a more social way.

Arcade games, table tennis

The space has arcade games, including bowling and motorcycle simulators, but also activities like table tennis. Peete taught the tailgate favorite cornhole to the Australian club.

One common thread for most of the boys: Fortnite, the massively popular, multiplayer shootout video game. They don’t have their consoles but they can still play on their phones and try to impress each other with renditions of the famous dances done by the game’s characters.

But the reason for their visit to Pennsylvania loomed.

“Can we play a [baseball] game?” Peete asked a volunteer at the Little League complex before the tournament started, suggesting that maybe the whole World Series could be moved up.

“There’s nothing else to do,” he said.

A majority of U.S. states has adopted technology that allows the federal government to see inside state computer systems managing voter data or voting devices in order to root out hackers.

Two years after Russian hackers breached voter registration databases in Illinois and Arizona, most states have begun using the government-approved equipment, according to three sources with knowledge of the deployment. Voter registration databases are used to verify the identity of voters when they visit polling stations.

The rapid adoption of the so-called Albert sensors, a $5,000 piece of hardware developed by the Center for Internet Security,  illustrates the broad concern shared by state government officials ahead of the 2018 midterm elections, government cybersecurity experts told Reuters.

CIS is a nonprofit organization based in East Greenbush, N.Y., that helps governments, businesses and organization fight computer intrusions.

“We’ve recently added Albert sensors to our system because I believe voting systems have tremendous vulnerabilities that we need to plug; but also the voter registration systems are a concern,” said Neal Kelley, chief of elections for Orange County, California.

“That’s one of the things I lose sleep about: It’s what can we do to protect voter registration systems?”

As of August 7, 36 of 50 states had installed Albert at the “elections infrastructure level,”according to a Department of Homeland Security official. The official said that 74 individual sensors across 38 counties and other local government offices have been installed. Only 14 such sensors were installed before the U.S. presidential election in 2016.

“We have more than quadrupled the number of sensors on state and county networks since 2016, giving the election community as a whole far greater visibility into potential threats than we’ve ever had in the past,” said Matthew Masterson, a senior adviser on election security for DHS.

The 14 states that do not have a sensor installed ahead of the 2018 midterm elections have either opted for another solution, are planning to do so shortly or have refused the offer because of concerns about federal government overreach.

Those 14 states were not identified by officials.

But enough have installed them that cybersecurity experts can begin to track intrusions and share that information with all states. The technology directly feeds data about cyber incidents through a non-profit cyber intelligence data exchange and then to DHS.

“When you start to get dozens, hundreds of sensors, like we have now, you get real value,” said John Gilligan, the chief executive of CIS.

“As we move forward, there are new sensors that are being installed literally almost every day. Our collective objective is that all voter infrastructure in states has a sensor.”

Top U.S. intelligence officials have predicted that hackers working for foreign governments will target the 2018 and 2020 elections.

Maria Benson, a spokesperson for the National Association of Secretaries of States, said that in some cases installations have been delayed because of the time spent working out “technical and contractual arrangements.”

South Dakota and Wyoming are among the states without Albert fully deployed to protect election systems, a source with knowledge of the matter told Reuters.

The South Dakota Secretary of State’s office did not respond to a request for comment. The Wyoming Secretary of State’s office said it is currently considering expanding use of the sensors.

India will send a manned flight into space by 2022, Prime Minister Narendra Modi announced Wednesday as part of India’s independence day celebrations.

He said India will become the fourth country after Russia, the United States and China to achieve the feat and its astronaut could be a man or a woman. The space capsule that will transport India’s astronauts was tested a few days earlier.

Rakesh Sharma was the first Indian to travel in space, aboard a Soviet rocket in 1984. As part of its own space program, India successfully put a satellite into orbit around Mars in 2014.

India won independence from British colonialists in 1947. Modi’s 80-minute speech, broadcast live from the historic Red Fort in New Delhi, comes months before national elections. 

Modi listed his government’s achievements in the past four years in reforming the country’s economy, reducing poverty and corruption. He announced a health insurance scheme for 500 million poor people providing a cover of 500,000 rupees ($7,150) per family a year.

He said India will become a growth engine for the world economy as the “sleeping elephant” has started to run on the back of structural economic reforms.

He said its economy was seen as fragile before 2014 but was now attracting investment. India is the sixth largest economy in the world and Modi said international institutions see India as giving strength to the world economy for the next three decades.

He said the structural reforms like a national tax replacing various national and local taxes, bankruptcy and insolvency laws, and a crackdown on corruption have helped transform the economy.
