Microsoft has a cure for data nuked by fat fingers if you're not afraid of the command line

Plus: Windows Forms on Arm64 in .NET 5, Live Events to live on

In brief While not able to undelete Microsoft's shuttered stores, accidentally borked files stand a chance at redemption thanks to the Windows File Recovery tool.

Undelete has been a thing in the Windows world for many a year, although Windows File Recovery (first spotted by WalkingCat) takes things a little further with support for the NTFS, FAT, exFAT and ReFS file systems as well HDD, SSD, USB and memory card smarts.

Sadly, for those hoping for salvation from friends-and-family support calls, the store app lacks a GUI and is command line only. Command line switches control the behaviour of the tool including filtering options for the recovered files.

Three modes are supported: Default (best for that immediate "oh heck" moment), Segment (for files deleted a while ago, or on a corrupted disk) and Signature (for supported file types, such as ZIP, and the recommended way to recover data from a FAT, exFAT or ReFS file system).

It's a neat tool, although power users will likely have their own selection of spanners and screwdrivers to undo whoopsies. It also requires Windows 10 19041 or later.

Windows Forms comes to Arm64 in .NET 5

Preview 6 of the Microsoft's .NET 5 framework was released last week and brought forth Windows Forms support for those lucky enough to be using a device running the company's Windows on Arm operating system.

Arm64 support first turned up in Preview 4 of the framework, but only in console and ASP.NET form. Windows Forms support will allow those running Visual Studio 16.7 to pop something more graphical onto the Windows on Arm desktop. WPF support, however, is still being worked on.

Giving rise to the spectre of Visual Basic (everyone's favourite .NET development platform, right?) the team has also added the ability to force Windows Forms apps to be single-instanced. More steps were also taken toward to glorious goal of "single file apps", although the Windows variant will require "a few extra runtime files".

The gang is past the midway point for .NET 5 now and is starting to "close down the release" ahead of the polish, fit and finish work required before General Availability can be declared.

Live Events increase get a life extension and teachers take back control (on Teams)

Finally, some good news for those using Microsoft's platforms for their events. The temporary increase in attendees for Microsoft 365 live events (in the likes of Teams, Stream and Yammer) to 20,000 will persist for a bit longer. Originally due to expire on 1 July, Microsoft has extended it to 1 October.

The move comes as the company continues to tinker with its Teams product. Having trailed features due to turn up later this year, the company has rolled out one that will be welcomed by those tasked with using the platform for education: it is now possible to stop students from joining Teams meetings unattended.

Students will also be unable to chat unless a teacher is present.

The "Students must wait in lobby" feature is due to hit in July, but last week's new toys can be enabled as soon as an administrator sets the meeting policy. It can take up to 24 hours for the new meeting policy to take effect, and the poppets need to inflict the latest version of the Teams desktop client on their systems. ®

  • Robotics and 5G to spur growth of SoC industry – report
    Big OEMs hogging production and COVID causing supply issues

    The system-on-chip (SoC) side of the semiconductor industry is poised for growth between now and 2026, when it's predicted to be worth $6.85 billion, according to an analyst's report. 

    Chances are good that there's an SoC-powered device within arm's reach of you: the tiny integrated circuits contain everything needed for a basic computer, leading to their proliferation in mobile, IoT and smart devices. 

    The report predicting the growth comes from advisory biz Technavio, which looked at a long list of companies in the SoC market. Vendors it analyzed include Apple, Broadcom, Intel, Nvidia, TSMC, Toshiba, and more. The company predicts that much of the growth between now and 2026 will stem primarily from robotics and 5G.

  • Deepfake attacks can easily trick live facial recognition systems online
    Plus: Next PyTorch release will support Apple GPUs so devs can train neural networks on their own laptops

    In brief Miscreants can easily steal someone else's identity by tricking live facial recognition software using deepfakes, according to a new report.

    Sensity AI, a startup focused on tackling identity fraud, carried out a series of pretend attacks. Engineers scanned the image of someone from an ID card, and mapped their likeness onto another person's face. Sensity then tested whether they could breach live facial recognition systems by tricking them into believing the pretend attacker is a real user.

    So-called "liveness tests" try to authenticate identities in real-time, relying on images or video streams from cameras like face recognition used to unlock mobile phones, for example. Nine out of ten vendors failed Sensity's live deepfake attacks.

  • Lonestar plans to put datacenters in the Moon's lava tubes
    How? Founder tells The Register 'Robots… lots of robots'

    Imagine a future where racks of computer servers hum quietly in darkness below the surface of the Moon.

    Here is where some of the most important data is stored, to be left untouched for as long as can be. The idea sounds like something from science-fiction, but one startup that recently emerged from stealth is trying to turn it into a reality. Lonestar Data Holdings has a unique mission unlike any other cloud provider: to build datacenters on the Moon backing up the world's data.

    "It's inconceivable to me that we are keeping our most precious assets, our knowledge and our data, on Earth, where we're setting off bombs and burning things," Christopher Stott, founder and CEO of Lonestar, told The Register. "We need to put our assets in place off our planet, where we can keep it safe."
