Good morning, Austin! Here's the latest tech news from around the Web this morning:
Silicon Valley companies delay releasing workforce diversity reports
The Wall Street Journal reports that several Silicon Valley companies -- including Twitter Inc. and Pinterest Inc. -- have delayed releasing their annual diversity reports as the industry struggles to show progress in adding more women and minorities to their ranks.
Apparently both Twitter and Pinterest were set to release their updates this month, about 16 months after their previous reports. This year, the Journal says, both companies say they are going to focus on hiring goals rather than racial and gender breakdowns.
Algorithmic guesswork could crack credit card info in six seconds
A group of English researchers looked into a recent cyber attack used to defraud Tesco Bank customers of £2.5 million last month.
They concluded that figuring out the card number, expiration date and security code of any Visa credit or debit card could take a criminal a mere six seconds and involved mostly guesswork, according to the Guardian.
The Newcastle University researchers said a "distributed guessing attack" method is able to circumvent security features and exploit vulnerabilities at Visa. Some sites have already changed their security settings in response to their findings.
Amazon's new grocery removes the need for cashiers

Called Amazon Go, the storex will operate by letting people scan their phones using the Go app on their way in and out, Recode says. Our own Addie Broyles also wrote about the new Amazon stores and how it could change grocery shopping.
