qubits coming to you

  • DNS Benchmark v2 is Finished and Available!
    Guest:
    That's right. It took an entire year, but the result far more accurate and feature laden than we originally planned. The world now has a universal, multi-protocol, super-accurate, DNS resolver performance-measuring tool. This major second version is not free. But the deal is, purchase it once for $9.95 and you own it — and it's entire future — without ever being asked to pay anything more. For an overview list of features and more, please see The DNS Benchmark page at GRC. If you decide to make it your own, thanks in advance. It's a piece of work I'm proud to offer for sale. And if you should have any questions, many of the people who have been using and testing it throughout the past year often hang out here.
    /Steve.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

    (You may permanently close this reminder with the 'X' in the upper right.)

The latest sn sounds as if quantum computers are a long way from being useful. However, IBM announced a 4000 qubit computer.

Also this one might not be closer to becoming a reality, there is another one promising a million qubits.

Though it might still take a while, it might be speeding. Just look at traditional computing, it started slowly and huge. Quantum computing has been slow, but it might be speeding up. Not sure it should be dismissed as something that might not happen for decades

If this is correct, they expect ECC to be vulnerable with a bit over 2000 qubits, so … 2025? or now?!?! o_O

Time to start looking at one time pads :)

They've always had a my interest being the only un-crackable encryption, but it has it's limitations. It's nearing the time to look into the past for the answer, paper in jars hidden in caves or buried somewhere. It's a time tested technique.
