Google to help publishers find malicious comments on articles

The technology, called Perspective, will review comments and score them based on how similar they are to comments people said were “toxic” or likely to make them leave a conversation.

Perspective examined hundreds of thousands of comments that had been labelled as offensive by human reviewers to learn how to spot potentially abusive language.

Perspective will not decide what to do with comments it finds are potentially abusive; rather publishers will be able to flag them to their moderators or develop tools to help commenters understand the impact of what they are writing.

Wi-Fi vulnerabilities beyond weak passwords

By now, most people know that an open Wi-Fi network allows people to eavesdrop on your traffic. Standard WPA2-PSK encryption is supposed to prevent this from happening — but it’s not as foolproof as you might think.

To keep private Wi-Fi networks secure, encryption is a must-have—and using strong passwords or passphrases is necessary to prevent the encryption from being cracked. But don’t stop there!

Open wi-fi means for example, at a coffee shop, while passing through an airport, or in a hotel. Open Wi-Fi networks have no encryption, which means everything sent over the air is “in the clear.” People can monitor your browsing activity, and any web activity that isn’t secured with encryption itself can be snooped on. Yes, this is even true if you have to “log in” with a username and password on a web page after signing in to the open Wi-Fi network.

Encryption — like the WPA2-PSK encryption we recommend you use at home — fixes this somewhat. Someone nearby can’t just simply capture your traffic and snoop on you. They’ll get a bunch of encrypted traffic. This means that an encrypted Wi-Fi network protects your private traffic from being snooped on.

Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) are two security protocols. And security certification programs developed by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found in the previous system, Wired Equivalent Privacy (WEP)

The problem with WPA2-PSK is that it uses a “Pre-Shared Key.” This key is the password, or passphrase, you have to enter to connect to the Wi-Fi network. Everyone that connects uses the same passphrase.

For instance, some wireless routers with a seemingly unique default SSID can be security risks, and even networks protected with WPA or WPA2 encryption have vulnerabilities if you’re using the pre-shared key (PSK) mode. Or perhaps your users are hopping on to neighbouring Wi-Fi networks, or snooping on each other’s traffic.

Pre-shared key WPA and WPA2 remain vulnerable to password cracking attacks if users rely on a weak password or passphrase. To protect against a brute force attack, a truly random passphrase of 20 characters (selected from the set of 95 permitted characters) is probably sufficient.

Brute forcing of simple passwords can be attempted using the Airbrick Suite starting from the four-way authentication handshake exchanged during association or periodic re-authentication.

How to unsend emails before regret kicks in

Sometimes it happens with us we send some emails to our friends but after some time we realize that we had written some more which may be hurt our friends. Or may be same at Job place, It’s especially bad right after you’ve sent that impulsively passive-aggressive email to your boss.

Then there’s good news, though. Popular email services offer undo send features. Bad news: you only have seconds to realize your mistake and hit “Undo.”


Phone: In Google’s Gmail iOS app, the setting is turned on by default. Shockingly, it’s not available in the Android app. In the recently updated iOS app, send an email and you’ll see the Undo button in the bottom right corner for approximately 5 seconds. Tap it and you can get back and edit your message.

Web: On the website, you have more control over how long the message delay can last. On the website, click the gear icon in the right corner, select Settings, scroll down and click Enable Undo Send. Choose the cancellation period (5, 10, 20, 30 seconds) then scroll to the bottom and hit Save. When you send a message, you’ll see the Undo button at the top of the window.

New laser technology creates 3D images in liquid display

 This mermaid graphic is created from laser-generated bubbles suspended in a liquid “screen” and illuminated with a halogen lamp.

Tokyo, Feb 24 (PTI) Scientists have developed a new technology that creates 3D images by using a laser to form tiny bubbles inside a liquid screen, allowing users to view images in a columnar display from all angles without any special glasses or headsets.

“Creating a full-colour updatable volumetric display is challenging because many three-dimensional pixels, or voxels, with different colours have to be formed to make volumetric graphics,” said Kota Kumagai, from Utsunomiya University in Japan.
