Google has updated its guidelines for publishing job openings that have been marked up with job posting structured data. Failure to adhere to these guidelines could result in a manual action.

Here is an overview of the new guidelines site owners will need to comply with when using job posting structured data.

  • Site owners will be required to remove a job posting when it is no longer available. This could involve either removing the entire posting, adding a noindex tag, or removing the job posting structured data.
  • Job posting structured data must only be used on individual job postings. It cannot be used on pages that display lists of all available job openings.
  • All information included in the job posting structured data must also be visible to users on the job description page.

Google emphasizes that these guidelines are being put in place to ensure an optimal job seeking experience for Google Search users.

Social networks have expanded popularity contests beyond the schoolyard, where users vie to become the next Instagram celebrity or at least have enough followers to be considered an “influencer.” 

But, unlike the schoolyard, anyone can buy popularity on social networks. Richard Roeper, the film critic for the Chicago Sun-Times, was suspended on Tuesday for buying 25,000 followers after a New York Times investigation revealed the practice was widespread.

The New York Times claimed that Roeper and others such as actor John Leguizamo, motivational speaker Eric Kaplan and British baking star Paul Hollywood purchased followers from a website called Devumi, which charges a mere $50 for 5,000 followers. 

Buying followers or paying for any type of interaction is against Twitter’s terms of service and may result in suspension. If a company buys more users to make itself seem more popular than it actually is, or a journalist buys them to meet a standard of followers that an employer has set, it’s also, as the Times noted, potentially fraud. 

Spotting fake Twitter uses is generally fairly easy, though fakers have gotten better at it over time. 

TwitterAudit

Tools like TwitterAudit can automatically scan your followers, revealing the number of fake followers (for free) and allowing you to delete and block them (for $5 a month). Use Luca Hammer’s Account Analysis tool to look at accounts individually. Consistent daily rhythms and constant retweeting of spammy handles or accounts are a good sign the user is a bot.

The quickest way to manually spot obvious fakers is to look at their profiles. Many advertise spammy links or use excessive hashtags. To look over many at once, click “followers” below your own profile image. Stop users from following you by clicking the three vertical dots above and to the right of their usernames, then click “block.”

Another quick way is to look for offset followers-to-following ratios, particularly if the following count is maxed out around 5,000. Twitter puts a limit on the number of accounts a user can follow until he or she has more followers. A user who has 171 followers and who is following 5,001 people is usually fake. 

It’s easier to do this with a third-party tool, as Twitter doesn’t list these counts on users’ following pages. StatusBrew is free, lists these numbers, and allows sorting based on followers and following. 

If the ratio is unclear, look at the user’s followers. Many of them may be obviously fake, as well. Just note that many Twitter users, especially large accounts, attract “fake” followers on their own. 

To really sniff out fakers, try right-clicking their profile images on Chrome and searching the web for their images. The Times reported that some of Devumi’s accounts appeared to be close approximations of actual people. The real accounts will often appear when you search for their images.

Why do fake followers even matter? With hundreds of millions of monthly active users, including the president of the United States and other important heads of state, Twitter has truly morphed from a microblogging platform into a method of communication that’s as accepted as a telephone. A user who inflates his or her follower count can leverage outsize impact on the outside world.

As the Times notes, they can “help sway advertising audiences and reshape political debates. They can defraud businesses and ruin reputations.”

Your social media accounts help you share your daily life with friends. But the mobile apps can go further than that, automatically alerting everyone when you become available online, read a message, or even visit a nearby location.

If you don't want your nearest and dearest to know what you're up to every minute of every day, as a general rule, try posting less frequently. Your photos, check-ins, and text updates can convey more information than you intend. Beyond that, here's how to tweak certain key settings on your apps to leave a smaller digital footprint.

Disable activity status

Many social apps will show your friends a notification when you're active, and even when you're offline, they can display the last time you visited. If you'd rather not broadcast your presence, many social networks will let you turn off this display.

In WhatsApp for Android, head to the main app menu by tapping the three dots on the top right, then choose Settings. If you're on an iOS device, you can access Settings straight from a tab on the bottom of the screen. Either way, your next step is to select Privacy. From this screen, tap Last seen and then Nobody to prevent anyone from knowing the last time you accessed WhatsApp.

Instagram also recently added an indicator of when you were last active. To turn this off, tap the Profile tab (a portrait silhouette) and then hit the menu button (on Android, it looks like three dots, and on iOS, it's a cog icon) on the top right. Finally, turn off Show activity status. As on WhatsApp, this hides your own activity but also prevents you from seeing when anyone else was last active.

Similarly, you can hide your active status in Facebook Messenger too, but it stops you viewing who else is currently online. Hit the People icon (the two portrait shapes) at the bottom of the screen, then tap Active, and turn the slider next to your own name to off. All your messages will still come through, but no one else will know when you're actually active in the app.

Turn off read receipts

When you're trying to preserve your privacy, one-on-one messaging options let you stay off the social media radar while still keeping in touch with people. So next time you're ready to post an update, consider pinging a few friends in a group chat on, say, WhatsApp, rather than broadcasting your activities to everyone you know. To preserve even more of your privacy, first turn off read receipts, those notifications that let your friends know when you've read their messages.

In WhatsApp for Android, for example, you can head to the main app menu (tap the three dots to the top right) then choose Settings, then Privacy, and untick the Read receipts box. It's the same on iOS, but you can access Settings straight from the bottom tab bar. With that done, no one will know when you've picked up your messages, but you won't know when your friends have seen theirs, either. On the same screen, you can tap Last seen and then Nobody to stop anyone from knowing when you were last active inside WhatsApp. Again, this setting blocks you from knowing the same about any of your contacts, so you can't have it both ways.

Twitter also lets you disable read receipts in your direct messages, so contacts won't know whether you've read their notes yet. Tap your avatar icon on the top left, pick Settings and privacy, go to Privacy and safety, and untick the Show read receipts button. The usual deal is in place here as well—once you untick that box, you won't be able to see when other people have picked up their direct messages either.

In the Facebook Messenger and Snapchat apps, you can't turn off read receipts. Still, sticking to individual chats in apps like these will preserve your lurker status better than posting on public social media networks.

Stay off the map

Social media apps can use your current location to feed you relevant ads and alert you about nearby events. But they can also broadcast your whereabouts—a feature you might want to turn off.

On Snapchat, for example, tap the ghost or Bitmoji icon on the top left. Then hit the cog icon on the top right, pick See my location, and make sure Ghost Mode is switched on. This mode prevents others from seeing where you are.

Facebook also shares your location with your friends. To disable this feature, tap the menu button (three horizontal lines) on the right-hand side of the screen. On Android, your next step is to pick Account Settings; on iOS, choose Settings, followed by Account Settings. Either way, follow up by tapping Location, selecting Nearby Friends, and setting the main toggle switch to off. This will prevent your friends from looking up your current location or getting alerts when you're in the area.

These networks can also attach your location to your status updates. On the bright side, Facebook and Twitter make it easy to avoid oversharing: They will only reveal your location if you specifically tap the location-tagging button while composing your post. Still, it's worth double-checking your message before you post, to make sure you're not accidentally revealing too much

Limit the audience

To use social media networks without broadcasting your presence, we've discussed sending direct messages to a few contacts rather than posting updates for all of them to see. In addition to that method, Facebook lets you limit the audience for your updates on a post-by-post basis.

Whenever you're composing an update, tap the audience selector button just under your name—it will probably say Friends, but it might have another label, depending on the default audience for your posts. Once you tap it, you can limit who will be able to see this update: Simply select More followed by Specific friends. This lets you hide your update from most people on Facebook while still adding to the News Feed of a few select contacts.

No other social media app gives you the same level of control. However, Twitter and Instagram do let you choose between posting public messages and limiting your audience to only your confirmed followers. Boosting your privacy in this way does mean that you'll have to specifically approve any new followers before they can see your posts, but it won't affect your list of current followers.

On Twitter, you can switch to a protected account by tapping your avatar on the top left, then choosing Settings and privacy, Privacy and Safety, and Protect your Tweets.

To do the same on Instagram, tap the Profile icon (the single portrait silhouette) followed by the menu button (on Android, it's three dots; on Instagram, it's a cog icon) on the top right of the screen. Then turn on the Private Account option.

About 10 percent of the email credentials of all those employed at Fortune 500 companies have been leaked on the dark web, according to a new study.

The VeriClouds report, which included data from a three-year period, that looked at 27 million Fortune 500 staffers and found about 2.7 million credentials among the eight billion stolen credentials found on the dark web. If that is not bad enough VeriClouds found that the stolen data was found in multiple locations thus increasing the possibility it is bought and used by malicious actors. The good news is the number represents a 7.5 percent decline from 2016.

“We see that on average each leaked Fortune 500 email address, associated with an online account, is found at 2.3 leaked data sources. Furthermore, the availability of credentials data increases when many bad actors repackage or combine older breach data and resell it,” the report stated.

The availability of these passwords opens a corporation up to any number of potential cyberattacks, including spearphishing, credential stuffing, and account takeover attacks, which can lead to bad guys having direct access to personnel or corporate networks.

Workers in the telecom, industrial and energy sectors saw the highest percentage of stolen credentials with 23 percent, 18 percent and 17 percent, respectively, leaked. The financial, technology and healthcare fields had more records on the Dark Web, but this is primarily due to the fact that those industries have more employees overall.

In many cases the Fortune 500 firm is not directly to blame for the data loss because their employees used their corporate email address, and possibly the same sign-on credentials, to create an account at a third-party website. If this entity suffers were to suffer a breach and the person has used the same login then the Fortune 500 company could be vulnerable.

Compounding the problem is a large number of weak passwords associated with their accounts.

“Computers, Office Equipment industry has the largest percentage of weak, compromised passwords with 25 percent, followed by Transportation Equipment and Telecommunications industries with 17.6 percent and 12.9 percent, respectively,” the report said.

When it comes to shear volume commercial banks have the highest number of weak or compromised passwords with 109,000; telecom is next with just over 100,000; and the computer, office equipment sector is third with 73,000.

The academic world is supposed to be a bright-lit landscape of independent research pushing back the frontiers of knowledge to benefit humanity.

Years of fingernail-flicking test tubes have paid off by finding the elixir of life. Now comes the hard stuff: telling the world through a respected international journal staffed by sceptics.

After drafting and deleting, adding and revising, the precious discovery has to undergo the ritual of peer-reviews. Only then may your wisdom arouse gasps of envy and nods of respect in the world’s labs and lecture theatres.

The goal is to score hits on the international SCOPUS database (69 million records, 36,000 titles – and rising as you read) of peer-reviewed journals. If the paper is much cited, the author’s CV and job prospects should glow.

SCOPUS is run by Dutch publisher Elsevier for profit.

It’s a tough track up the academic mountain; surely there are easier paths paved by publishers keen to help?

Indeed – but beware. The 148-year old British multidisciplinary weekly Nature calls them “predatory journals” luring naive young graduates desperate for recognition.

‘Careful checking’

“These journals say: ‘Give us your money and we’ll publish your paper’,” says Professor David Robie of New Zealand’s Auckland University of Technology. “They’ve eroded the trust and credibility of the established journals. Although easily picked by careful checking, new academics should still be wary.”

Shams have been exposed by getting journals to print gobbledygook papers by fictitious authors. One famous sting reported by Nature had a Dr. Anna O Szust being offered journal space if she paid. “Oszust” is Polish for “a fraud”.

Dr Robie heads AUT’s Pacific Media Centre, which publishes the Pacific Journalism Review, now in its 23rd year. During November he was at Gadjah Mada University (UGM) in Yogyakarta, Central Java, helping his Indonesian colleagues boost their skills and lift their university’s reputation.

The quality of Indonesian learning at all levels is embarrassingly poor for a nation of 260 million spending 20 percent of its budget on education.

The international ranking systems are a dog’s breakfast, but only UGM, the University of Indonesia and the Bandung Institute of Technology just make the tail end of the Times Higher Education world’s top 1000.

There are around 3500 “universities” in Indonesia; most are private. UGM is public.

UGM has been trying to better itself by sending staff to Auckland, New Zealand, and Munich, Germany, to look at vocational education and master new teaching strategies.

Investigative journalism

Dr. Robie was invited to Yogyakarta through the World Class Professor (WCP) programme, an Indonesian government initiative to raise standards by learning from the best.

Dr. Robie lectured on “developing investigative journalism in the post-truth era,” researching marine disasters and climate change. He also ran workshops on managing international journals.

During a break at UGM, he told Strategic Review that open access – meaning no charges made to authors and readers – was a tool to break the user-pays model.

AUT is one of several universities to start bucking the international trend to corral knowledge and muster millions. The big publishers reportedly make up to 40 percent profit – much of it from library subscriptions.

Pacific Journalism Review’s Dr. David Robie being presented with a model of Universitas Gadjah Mada’s historic main building for the Pacific Media Centre at the editor's workshop in Yogyakarta, Indonesia.

According to a report by AUT digital librarians Luqman Hayes and Shari Hearne, there are now more than 100,000 scholarly journals in the world put out by 3000 publishers; the number is rocketing so fast library budgets have been swept away in the slipstream.

In 2016, Hayes and his colleagues established Tuwhera (Māori for “be open”) to help graduates and academics liberate their work by hosting accredited and refereed journals at no cost.

The service includes training on editing, presentation and creating websites, which look modern and appealing. Tuwhera is now being offered to UGM – but Indonesian universities have to lift their game.

Language an issue
The issue is language and it’s a problem, according to Dr. Vissia Ita Yulianto, researcher at UGM’s Southeast Asian Social Studies Centre (CESASS) and a co-editor of IKAT research journal. Educated in Germany she has been working with Dr. Robie to develop journals and ensure they are top quality.

“We have very intelligent scholars in Indonesia but they may not be able to always meet the presentation levels required,” she said.

“In the future, I hope we’ll be able to publish in Indonesian; I wish it wasn’t so, but right now we ask for papers in English.”

Bahasa Indonesia, originally trade Malay, is the official language. It was introduced to unify the archipelagic nation with more than 300 indigenous tongues. Outside Indonesia and Malaysia it is rarely heard.

English is widely taught, although not always well. Adrian Vickers, professor of Southeast Asian Studies at Sydney University, has written that “the low standard of English remains one of the biggest barriers against Indonesia being internationally competitive.

“… in academia, few lecturers, let alone students, can communicate effectively in English, meaning that writing of books and journal articles for international audiences is almost impossible.”

Though the commercial publishers still dominate there are now almost 10,000 open-access peer-reviewed journals on the internet.

“Tuwhera has enhanced global access to specialist research in ways that could not previously have happened,” says Dr Robie. “We can also learn much from Indonesia and one of the best ways is through exchange programmes.”

Google Photos can now recognize your pets

One of Google Photos’ best features is face recognition for easier grouping, search, and sharing with friends and family. Google is now extending that detection and adding naming support for your cats and dogs.

The picture backup and management service has long been able to recognize animals in general and surface them in search results. However, users would not be able to easily find pictures of just their pet and have to rely on general lookup terms like “dog” or “cat.”

That is changing today, with Google Photos now recognizing specific dogs or cats as long as there is a clear shot of their face. Users are able to label them by name and in turn have them treated as people when looking for pictures.

It appears that there is a new combined “People & Pets” section where animals show up. From there, tapping through to those images should feature the ability to “Add a name.”

Other pet-centric features already available in Google Photos include the ability to search by specific cat or dog breed. Additionally, users can search for animals with emoji.

Today’s new features complement Photos’ existing ability to make movies from images of your pets. Since May, some users have been greeted by clips of their pets, but users can also manually make movies by heading to Assistant. Here, they have control over images and the background soundtrack.

The pet recognition and tagging feature is rolling out in most countries starting today.

Beijing's bid to mine space rocks could bring so much wealth back to Earth that it crashes the planet's economy

CHINA plans to build a base on an asteroid and begin mining billions or even trillions of dollars worth of precious metals.

Yesterday, a top scientist revealed plans to land an unmanned craft on a space rock, potentially putting Beijing’s asteroid miners in direct competition with American space prospectors.

Asteroids could contain incredible riches worth billions or even trillions

The asteroid will then be mined or even used to piggyback probes into deep space.

Ye Peijian, a deep-space exploration expert at the China Academy of Space Technology, told an “asteroid exploration forum” that 900 space rocks zoom past Earth every year.

Many of these priceless asteroids contain vast amounts of metals such as platinum, iridium or rhodium.

“In the near future, we will study ways to send robots or astronauts to mine suitable asteroids and transport the resources back to Earth,” he said, according to China Daily.

“In the long term, we will consider using resources from asteroids to build facilities in space or to provide materials to support interstellar travel.”

The asteroids could also be used on deep space missions and serve as “bases for interstellar exploration”.

The Chinese boffin suggested an unmanned probe could hitch a ride on the asteroid and then travel off into deep space, which would drastically cut down on the amount of fuel needed to power the probe.

The global investment bank Goldman Sachs has claimed mining asteroids for precious metals is a “realistic” goal.

It is believed an asteroid the size of a football field could be worth up to £40 billion.

However, bringing that much platinum back to Earth is likely to crash the precious metal market - and probably the rest of the economy with it.

Earlier this year, NASA said it was planning a mission to an asteroid worth £8,072 quadrillion ($10,000 quadrillion), according to Lindy Elkins-Tanton, lead scientist on the mission.

It is called 16 Psyche and is a massive hunk of the iron and nickel.

The mysterious "metal world" was formed during the turbulent birth of our solar system.

It is valued at £8,072 quadrillion ($10,000 quadrillion), according to Lindy Elkins-Tanton, the lead scientist on the NASA mission.

We’re all worried that instead of improving the world by making information more accessible, the internet has done the opposite by creating echo chambers that further entrench our prejudices.

Most of the discussion in this area tends to revolve around political views. Thanks to the decline of traditional media and the proliferation of new online media outlets, people are less exposed to ideas that contradict their beliefs.

However there’s a bigger, far more damaging filter bubble out there. And because its existence is at the commercial core of the modern-day media machine, almost nobody is willing to admit its existence.

Welcome to the bad-news bubble

Forget fake news. Our real problem is balance. Respectable news outlets say they’re giving us an objective view of the world, yet drown us in a daily deluge of conflict and negative headlines: nuclear sabre rattling in North Korea, South Sea games of chicken with China, chemical attacks on children in Syria, the mother of all bombs in Afghanistan. And then there’s the runaway temperatures in the Arctic, economic collapse in Venezuela, authoritarianism in Turkey, the slow-motion disaster of Brexit in the UK, and, of course, the never-ending headlines from Washington overshadowing it all. It’s manufactured drama, and we can’t tear our eyes away.

All this bad news is great for business. According to a report released by Neilsen in April, news consumption across all media in the US, including cable TV, radio, traditional broadcast TV, and smartphones, has risen by 18% in the last year. Other English-speaking countries like Australia, Canada, and the United Kingdom will have experienced similar increases.

There’s no incentive to report good news in the modern-day attention economy, because it doesn’t get traction. Sure, democracy dies in darkness. But you know what else dies in darkness? Optimism.

Sure, democracy dies in darkness. But you know what else dies in darkness?

Optimism.Every headline, every news report, every viral video tells us that things are falling apart. No wonder we’re all in despair. Starving children, angry analysts, and dying polar bears make for easy availability heuristics: We tend to judge the frequency and probability of something happening based on how easily we can bring it to mind, and these things are memorable and iconic. And every time we discuss the lying politicians at a dinner party or see someone complaining about them on Facebook, we retrieve those memories and make them even stickier.

Bad news is the only news because it’s an addictive product. That’s why it’s everywhere. It doesn’t matter that we’re living in the wealthiest, healthiest, most peaceful, and most democratic time in human history. It doesn’t matter that poverty is decreasing, that fewer people are dying from war, or that more mothers survive childbirth. It doesn’t matter that human rights are improving or that more kids are learning to read and write than ever before. These stories are invisible because they don’t shock us or make us angry. And that means they don’t sell.

It’s not clear whether more visibility would make a difference, either. Thanks to something known as the kickback effect, evidence that contradicts our worldview only further entrenches it. It makes us feel good to stick to our guns, and we’re great at rationalization. Research shows that we experience a genuine rush of dopamine when processing information that supports our beliefs. That means that no amount of statistical evidence will convince progressives that they’re not morally superior, conservatives that immigration is good for the economy, or environmentalists that GMOs are safe. Similarly, evidence cannot compete with most people’s belief that poverty is rampant and that war and terrorism have never been worse.

Some good news

So how do we break out of the bad-news bubble? Read more good news—there’s plenty out there!

To start, here’s some from the past week that you probably didn’t here about:

Composite; NASA

Scientists believe they may have discovered evidence of a parallel universe that crashed into our own in a galactic impact mirroring a car crash.

Since 2004, when it was first spotted by NASA, scientists have been baffled by the discovery an unusually cold region of space which is 1.8 billion light years across and colder than its surroundings.

It was thought the region might have been a trick of light or it was colder because it had 10,000 less galaxies than other areas of the same size.

Now a new study has stumbled upon an incredible possibility, that the ‘Cold Spot’ cannot be explained as a void and was not due to “line-of-sight” effects.

Instead, researchers at Durham University believe it could be the first evidence of the “multiverse.”

They believe a parallel universe could have smashed into ours affecting it in a way similar to a multiple vehicle pileup.

That impact was so incredible, according to this research, that it pushed energy out of a huge region of space resulting in the Cold Spot.

“Perhaps the most exciting explanation is that the Cold Spot was caused by a collision between our universe and another bubble universe, believe it or not,” said Professor Tom Shanks, an astronomer at Durham University and a co-author of the study.

“If further, more detailed, analysis proves this to be the case then the Cold Spot might be taken as the first evidence for the multiverse.”

“I remember some scientists suggesting that there could be detectable effects on the galaxy distribution after this ‘cosmic shunt’ of two universes colliding.

“Basically colliding universes could leave a slightly anisotropic galaxy distribution in our own universe — a bit like a pileup on the motorway.

“So we can look for this to test how seriously to take these ideas.”

According to The Guardian, “each universe carries its own different version of reality.”

“There will be one where you wrote this column and I read it, even a really weird one in which Donald Trump uses Twitter to spread nothing but amusing cat videos,” Stuart Clark wrote in the publication.

The Cold Spot occurred at the formation of the universe more than 13 billion years ago.
