Facebook "Account Disabled" Bug Affects Only Women?

Glitch fixed, but affected users must now prove to Facebook who they are

Facebook "Account Disabled" Bug Affects Only Women?

Yesterday, there were news stories like this one at CNNMoney.com and this one in the San Francisco Chronicle reporting that some unknown number of Facebook users had been cut off from their accounts. More strangely, the users affected seemed to be all women.

I don't ever recall hearing of a gender specific software bug before.

The CNNMoney story quotes a Facebook spokesperson as saying:

"The bug, which was live for a short period of time, caused a very small percentage of Facebook accounts to be mistakenly disabled. Upon discovering the bug, we immediately worked to resolve it. It's now been fixed, and we're in the process of reactivating and notifying the people who were affected."

The affected users - Facebook refuses to say how many made up that "small percentage"  or confirm that those negatively affected were only women - received a message when they tried to log in that their account had been disabled. They were then directed to a Facebook FAQ page that told them they needed to provide credentials proving that there were in fact who they said they were.

The SF Chronicle story says users were told to:

"Please upload a government-issued ID to this report and make sure that your full name, date of birth, and photo are clear. You should also black out any personal information that is not needed to verify your identity (e.g., social security number)."

"If you do not have access to a scanner, a digital image of your photo ID will be accepted as well. Rest assured that we will permanently delete your ID from our servers once we have used it to verify the authenticity of your account."

If any of you were affected by the bug (especially if you weren't a woman), let me know. And let me know how responsive Facebook has been in restoring your account.

Metamaterials Could Solve One of 6G’s Big Problems

There’s plenty of bandwidth available if we use reconfigurable intelligent surfaces

For all the tumultuous revolution in wireless technology over the past several decades, there have been a couple of constants. One is the overcrowding of radio bands, and the other is the move to escape that congestion by exploiting higher and higher frequencies. And today, as engineers roll out 5G and plan for 6G wireless, they find themselves at a crossroads: After years of designing superefficient transmitters and receivers, and of compensating for the signal losses at the end points of a radio channel, they’re beginning to realize that they are approaching the practical limits of transmitter and receiver efficiency. From now on, to get high performance as we go to higher frequencies, we will need to engineer the wireless channel itself. But how can we possibly engineer and control a wireless environment, which is determined by a host of factors, many of them random and therefore unpredictable?

Perhaps the most promising solution, right now, is to use reconfigurable intelligent surfaces. These are planar structures typically ranging in size from about 100 square centimeters to about 5 square meters or more, depending on the frequency and other factors. These surfaces use advanced substances called metamaterials to reflect and refract electromagnetic waves. Thin two-dimensional metamaterials, known as metasurfaces, can be designed to sense the local electromagnetic environment and tune the wave’s key properties, such as its amplitude, phase, and polarization, as the wave is reflected or refracted by the surface. So as the waves fall on such a surface, it can alter the incident waves’ direction so as to strengthen the channel. In fact, these metasurfaces can be programmed to make these changes dynamically, reconfiguring the signal in real time in response to changes in the wireless channel. Think of reconfigurable intelligent surfaces as the next evolution of the repeater concept.
