Sydney Harbour
WEEKLY NEWSLETTER 27 MAY - 1 JUNE 2019

Hello and Welcome,

Call for literary talent and/or Graphic artists:

We are looking for members with writing skills.

Can you put together an attractive brochure showing the aims and objectives of the Club and listing the advantages of joining up?

Ideally, this should be just a single page with text and graphics.

This could then be printed and distributed to bulletin boards in Libraries, local Malls and meeting Halls.

Many thanks — Ed.

“Problems with Windows 10 update: Update Crashes and System Restore Windows 10 Won't boot”:

See the guru3d article by Hilbert Hagedoorn on: 05/21/2019 08:11 AM | source: bleepingcomputer.

Microsoft's updates aren't a success story for sure. The most recent update causes users to get stuck during the installation of the update, well that or the system as a whole does not want to restart after the installation which actually is even worse.

Windows 10 devices with system protection enabled and a system restore point created prior to the installation of one or more Windows 10 updates will no longer get their system started. When users attempt to restore the system after the updates are installed, a "Stop error (0xc000021a)" will follow.

Microsoft:

During the system restore process, Windows temporarily stages the restoration of files that are in use. It then saves the information in the registry. When the computer restarts, it completes the staged operation.

In this situation, Windows restores the catalog files and stages the driver .sys files to be restored when the computer restarts. However, when the computer restarts, Windows loads the existing drivers before it restores the later versions of the drivers. Because the driver versions do not match the versions of the restored catalog files, the restart process stops.

Redmond offers a procedure that can be followed to recover from the failed restart caused by this known issue which requires users to enter the Windows Recovery Environment (Windows RE or WinRE) by restarting the computer again after the failure.

To be able to circumvent the restart failures caused by this known issue, users may have to either restart two times in a row or use a hardware restart switch. [ Do they mean "reset" switch? — Ed. ]

Once the Windows Recovery Environment is on the screen, follow these steps:

  • Select Troubleshoot > Advanced options > More recovery options > Startup settings, and then select Restart now.
  • In the list of startup settings, select Disable driver signature enforcement. (Note: You may have to use the F7 key to select this setting.)
  • Allow the startup process to continue. As Windows restarts, the system restore process should resume and finish.

Following the steps listed above will allow users to restore the computer to the restore point chosen before the Stop error (0xc000021a) was triggered.

“Hewlett Packard Enterprise acquires supercomputer maker Cray in the race to 'exascale' performance”:

See THE VERGE article by Nick Statt | @nickstatt | May 17, 2019, 3:37pm EDT.

HPE bought Cray for about $1.4 billion

Hewlett Packard Enterprise, not to be confused with the personal computing brand from which it split in 2015, said today that it acquired Cray, an iconic maker of supercomputers with a rich history in the computing industry. The deal is said to be valued at $1.4 billion.

Cray, which was founded in 1972 by "the father of supercomputing," Seymour Cray, is currently contracted to build two of the world's fastest supercomputers for two US Department of Energy Labs: the Oak Ridge National Laboratory and the Argonne National Laboratory. Both systems, one called Frontier being built in partnership with AMD and one called Aurora with Intel, are promised to bring so-called "exascale" performance, with raw performance power in excess of 1.5 exaflops, or 1.5 quintillion calculations per second. [ This is 1.5×1018 floating point operations per second — Ed. ]

COMPUTING FIRMS ARE RACING TO REACH EXASCALE PERFORMANCE, OR A QUINTILLION OPERATIONS PER SECOND

Such exascale supercomputer systems do not yet exist, and it makes sense HPE would want its own stake in upcoming "exascale opportunities," for which the company says there is a growing market of primarily government contracts, currently estimated at $4 billion over the next half-decade. Currently, IBM is the maker of the world's two fastest supercomputers, Summit and Sierra.
