Windows 10 Pro Creator’s edition 2017 update breaks VMware Workstation 12 and 12.5 NIC Build 1703

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

Crypto Currencies or Gold?

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

Estimating the space requirements for a small server room

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 a Trump win means to the technology sector

What a Trump win means to the technology sector

By Bob Pellerin

 

President-elect Trump may shake up things in more than the wall construction industry. As some of you may have noticed recently, executives from well-known companies such as Amazon, Netflix, and Salesforce, to name but a few, were rather vocal about president-elect Donald Trump. He’s been known for his tremendous sense of humor, right? All right, so perhaps having even one of these industry leaders comparing him to certain historical dictator might have been a bit much.

Unfortunately for some of us in the technology industry, we may be seeing a lot of red laser dots appear on our foreheads as we congregate in boardrooms soon. That might be a flagrant exaggeration, but wasn’t Mr. Trump threatening to boycott Apple? Wasn’t he going after Amazon for antitrust violations? What about Facebook? Didn’t they have suspect immigration policies? Surely Mr. Trump was kidding when he accused Google of suppressing negative headlines about Hilary Clinton!

All the bad blood and accusations aside, you should be worried regardless. He won, so that may satisfy the new commander in chief and spare the technology sector from retaliation. What we should all really worry about are tax-related statements he made to the press. There’s a slight possibility the president-elect may remember his own words about Amazon. “Amazon is getting away with murder, tax-wise”.

If your tax advisors keep telling you to save taxes by declaring all that income in Ireland or some not so far tax haven, perhaps you should remember the public attention you may be getting in the coming 4 years and prepare accordingly. What may be perfectly legal might not look so great when coming out of president-elect Trump’s mouth live on television.
