As some of you may know we are hard at work on Bitcoin-related projects. We were affected by the NiceHash Mining theft. Here are the answers to some common questions about the incident.
What was stolen? Their Bitcoin wallet. All of it. Continue reading
Ever since I wrote that article about bitcoins, a fair number of readers have been asking about mining and general investment into bitcoins. We’re putting together a new article. We hope to review some bitcoin gear in the coming months. Continue reading
Just when you thought it was safe to upgrade a Pink Screen of Death (PSoD) is confirmed. If you are thinking of upgrading from 6.5 u2 to update 1 you may want to hold off. This problem has no resolution and was officially documented by VMware on Oct 25, 2017.
- Upgrading to ESXi 6.5 Update 1 produces a PSOD.
- ESXi host using 10GB NICs
As we tweeted on Oct 17, 2017, a major WPA2 flaw has been discovered by Mathy Vanhoef of KU Leuven in Belgium. WPA2’s cryptographic protocols could be exploited to read and steal data that should be secure. Continue reading
Exporting to an OVF file results in an unsupported hardware family vmx-12 error. Here are a few possible fixes.
I spent hours exporting a virtual machine (vm) to an OVF format only to discover that VMware vSphere 6.5 gives me an error when I tried to deploy it.
Error message: Unsupported hardware family ‘vmx-12’ error ( also applies to vmx-10, and vmx-11 )
Cause: You created the VM using Workstation 11 or 12/12.5 and didn’t set the vm version to 10 or below before creating the OVF. Continue reading
If you read my posts then you know we’re been here before. The Windows 10 Pro update called the Creators Edition released in September 2017 (Build 1703) breaks your VMs running on VMware Workstation pro 12 or 12.5. It is possible that 11 or earlier may have this same problem.
Instead of simply sending you back to my old post I thought I would share how to fix this problem quickly.
Summary: The VMs suddenly no longer see the Network Interface Card (NIC) of your computer running Windows 10 Pro. Just to be clear, the VMs can be running any version of Windows and have this issue. The Workstation is running on Windows 10 Pro. Continue reading
It goes without saying that most people have heard of crypto currencies. Those digital “dollars” based on something called a block chain. Allow me to confess that I didn’t pay much attention to Bitcoin at first. As an IT expert and a writer about the financial markets many are shocked that I didn’t “get it”. I wanted to share with others the “cons” I saw with Bitcoin. Continue reading
Windows 10 Remote Desktop Services Port Redirector crashes. Hanging or freezing isn’t usually. I imagine this problem goes undetected since so few people turn on the remote desktop service on their Windows 10 computers. In this particular case, the problem was on a Dell Optiplex. It started after an update. Continue reading
Small companies relocate all the time. Many companies appear to get stuck improvising rooms to put the equipment and often end up using a closet. In such cases, poor ventilation ends up causing undo stress of the equipment and bringing some devices to a premature end. I saw one switch that looked like it had partially melted on the bottom. The textured plastic was smooth and discolored. Continue reading
What to do if the Windows 10 June 2017 update hangs on restart. Some people report seeing the progress go up to 28% or so before having issues. This is usually when the Windows reboot is taking forever. A long time has passed and you’re not even sure if it is still working or if it is frozen. Continue reading
