"Eric Schmidt, executive chairman of Google, was asked to act to take down terrorist-sympathising websites from his search engines during a question and answer session at the literary festival on Saturday. This weekend MPs, including the Labour politician Paul Flynn, called on the company to prevent searches listing sites for groups such as the Islamist organisation Al Shabaab. Schmidt said: "We cannot prima facie identify evil and take it down. We have taken the decision that information if it's legal, even if it's despicable, will be indexed.""

"DDoS attacks are also becoming more common. Brian Krebs, an independent security researcher, observed earlier this month that the "source code" to the Mirai botnet had been released by a hacker group, "virtually guaranteeing that the internet will soon be flooded with attacks from many new botnets powered by insecure routers, IP cameras, digital video recorders and other easily hackable devices""

"If Facebook cared about unfair profiling and privacy abuse, for instance, it would probably not have started grouping its users together based on their "Ethnic Affinity". It wouldn't then allow that ethnic affinity to be used as a basis for excluding users from advertisements, and it certainly wouldn't allows that ethnic affinity to be used as a basis for potentially illegal discrimination in real estate advertising."

"This person or group, who go by the names BestBuy and Popopret, recently spammed an ad to folks on Jabber, an instant messaging service. They offered to perform a distributed denial of service (DDoS) attack on whomever their client(s) wanted, and they backed up their offer by claiming to wield the ability to perform some of the strongest DDoS attacks ever seen. Recent events in the history of the internet show us that these kind of attacks - if these hackers indeed have the power they claim - can wreak internet havoc by blocking user access to a range of some of the web's most popular destinations."

"The family of a California design student killed in November's terror attacks in Paris have sued Twitter Inc, Google and Facebook Inc, claiming the social media companies provide "material support" to the militant group Islamic State."

"Participants used an app on their phones to record 30-second intervals of themselves reading a piece of text, describing a positive experience, then describing a negative experience. Doctors also took recordings from a control group of 25 patients who were either healthy or getting non-heart-related tests. The doctors found 13 different voice characteristics associated with coronary artery disease. Most notably, the biggest differences between heart patients and non-heart patients' voices occurred when they talked about a negative experience."

"The new documents reveal that a GCHQ unit dubbed the Joint Threat Research Intelligence Group, or JTRIG, launched an operation called Rolling Thunder against the hacker collective in 2011. That operation included using DDoS attacks as well as malware to slow down the hackers and later identify them, as first reported by as reported by NBC News on Wednesday."

"Sophie Bishton, a junior doctor, was "fed up with traditional learning and being talked at all the time" and so founded the Twitter finals revision group (known as twitfrg) in October 2012. Users are invited to participate in a scenario in real time. Prior to the event, revision notes related to the case are made available online. At a prearranged time, a tweet is sent marking the beginning of the scenario. "

"Many hope to reach the economically stable countries in northern Europe, and use WhatsApp's messaging system as a virtual road map to help them navigate their journey. They stick to groups of their countrymen, connecting through friends of friends. Unlike some other ways of communicating, WhatsApp is free, and only requires that the user have access to the internet."

"Prominent Bahraini activist Nabeel Rajab was sentenced to six months in jail on Tuesday after criticizing the country's security forces on Twitter. Rajab was arrested in October for tweeting that Bahrain's security organizations are "ideological incubators" for those who join terrorist groups."

"It's clear that surveillance affects a broad group of people, with real painful consequences for their lives. We've seen journalists being monitored, lawyers having their client confidentiality broken, victims of police misconduct being spied on and environmental campaigns infiltrated. These people are not criminals, and yet when we have a system of mass surveillance, they become targets for increasingly intrusive powers. "

"Luckily for the kid, it was only a single tweet. Had several students gotten together to form a study group, they might have been prosecuted for felony interference with a business model and gotten the death penalty. Do you suppose Pearson has hidden microphones set up around the schools so they can also listen in and see if students discuss the tests during lunch? I ask because that is basically the offline version of the student's infraction."

"Major Wall Street institutions were cracked wide open by a phishing scam from FIN4, a hacker group that, unlike its competition, can write convincingly and employs some basic smarts about why people open attachments."

""While surveillance technology may threaten the privacy of us all, surveillance efforts have historically been used to intimidate and oppress certain communities and groups more than others, including those that are defined by a common race, ethnicity, religion, national origin, income level, sexual orientation, or political perspective.""

"Facebook enables advertisers to promote content to nearly 900,000 people interested in "vaccine controversies", the Guardian has found. Other groups of people that advertisers can pay to reach on Facebook include those interested in "Dr Tenpenny on Vaccines", which refers to anti-vaccine activist Sherri Tenpenny, and "informed consent", which is language that anti-vaccine propagandists have adopted to fight vaccination laws."

""The idea that we can have counter-speech when [Facebook] groups become brigade mobs is ludicrous," said Renee DiResta, an expert in online misinformation and co-founder of Vaccinate California. "It makes just participating as an everyday citizen a high-stakes ordeal.""

"Vietnam has introduced a new cybersecurity law, which criminalises criticising the government online and forces internet providers to give authorities' user data when requested, sparking claims of a "totalitarian" crackdown on dissent. The law, which mirrors China's draconian internet rules, came into effect on 1 January and forces internet providers to censor content deemed "toxic" by the ruling communist government. Vietnam's ministry of public security said it will tackle "hostile and reactionary forces", but human rights groups said it was authorities' latest method of silencing free speech."

"SINGAPORE - In the not too distant future, surveillance cameras sitting atop over 100,000 lampposts in Singapore could help authorities pick out and recognise faces in crowds across the island-state. The plan to install the cameras, which will be linked to facial recognition software, is raising privacy fears among security experts and rights groups. The government said the system would allow it to "perform crowd analytics" and support anti-terror operations."

"In Neural Photo Editing With Introspective Adversarial Networks, a group of University of Edinburgh engineers and a private research colleague describe a method for using "introspective adversarial networks" to edit images in realtime, which they demonstrate in an open project called "Neural Photo Editor" that "enhances" photos by predicting what should be under your brush."
