Dell Precision 3530 and Symantec Ghost

Be sure to change SATA Operation from RAID to AHCI in the BIOS Settings before running Symantec Ghost from a memory stick. The former setting will effectively hide your NVMe drive. Better safe than sorry, reinstate the RAID selection afterwards. Ref.: https://www.dell.com/support/article/us/en/04/sln301036/windows-10-install-with-nvme-ssd-and-sata-drives?lang=en

hostmaster@ximalas.info is compromised. Password must be changed

This is all so cute. Scammers don’t bother doing any research at all, but harvest our email addresses and send their junk emails high and low. Scammers usually have no sense of spelling nor grammar, which is the case in the matter at hand. Sorry, I don’t scare so easily. Continue reading hostmaster@ximalas.info is compromised.

Upgrading localbase on 13.0-CURRENT using ports-mgmt/synth

I upgraded base from 12.0-ALPHA9 to 13.0-CURRENT (r339639) on a VM today. While preparing for rebuilding localbase, I wiped clean /var/synth/live_packages/{All,Latest}/*, and cleaned the ccache repo stored in /var/cache/ccache. Trouble arose when I ordered ports-mgmt/synth to rebuild some 116 ports according to a specification stored in a local metaport. DEFAULT_VERSION+=ssl=base was being used at the time.

iperf3 and Chelsio T6225-CR

I ran four tests yesterday using iperf3. The T6225-CR NIC still runs with Chelsio’s SM10G-SR optics. It’s amazing that receiving TCP streams runs at full speed. Sending TCP streams limps away only at a few megabits per second. This wasn’t expected at all. Even IPv6 runs faster than IPv4 for these particular tests. The Cisco switch at the other end uses Fiberworks’ SFP-10G-SR optics. Does anyone have any clues? Continue reading iperf3 and Chelsio T6225-CR

Chelsio T6225-CR and TOE

After upgrading to a recent base/stable/11, I noticed ifconfig -m now displays two more bits:

Error 1603 when installing Microsoft Visual C++ 2008 Redistributable and Autodesk Revit 2019

Today I got error 1603 while installing Autodesk Revit 2019 on a student’s laptop. The best solution is to uninstall all Microsoft Visual C++ runtimes, reboot the computer, and let the Revit installer get its way installing the supplied versions.
