In two recent blog articles (here and here) I have called out the USPTO for programming Patentcenter so that its Acknowledgment Receipts list false information about what a filer uploaded in Patentcenter. The practitioner wishing to independently check such things will thus be interested to know how to calculate a SHA-512 hash (Wikipedia article, what the USPTO calls a “message digest”) of a PDF or DOCX file on the practitioner’s hard drive. One way to do this is with a command-line utility within Microsoft Windows. Continue reading “How to calculate SHA-512 hashes in Microsoft Windows”
Getting a VPN
The other day I heard from a friend of mine that somebody they know “has a living situation in which she needs a VPN” and the question was, could I recommend “a good VPN”. These questions always drive me crazy. I will explain why. Continue reading “Getting a VPN”
Being alerted when a vehicle enters your driveway

If I am in my house and I hear a certain chime, it tells me that a vehicle has entered the driveway. I find this to be very convenient. Maybe this is during the day and it lets me know that a UPS truck or Fedex truck is arriving. Or maybe it is in the evening and it lets me know that the expected dinner guests are arriving. Either way, I can bestir myself and head down to the front door and greet the arriving visitor with a bit of advance warning. How does it work, you might wonder? I will tell you. The photograph above right helps to explain how it works. Continue reading “Being alerted when a vehicle enters your driveway”
Time to switch to an EV

In a weird way I got lucky. Fifteen months ago, two things happened:
- an inattentive driver smacked into the back of my ICE car, totaling it (and thankfully not injuring anybody), and
- a client of my firm that had left some bills unpaid for a very long time happened to pay its bills rather unexpectedly.
I then paid cash for an electric vehicle. Continue reading “Time to switch to an EV”

Our telephone company VoIP.ms sets an example again
Around five years ago, our firm migrated nearly all of our telephone services to a company called VoIP.ms. Not once have we regretted it, and again and again we have seen reasons to feel good about this choice. Today we see this company once again setting an example. Here is what they have done:
At VoIP.ms we are deeply touched by the situation impacting the Ukrainian people. As a token of solidarity, effective today, VoIP.ms will be absorbing all costs for call termination to Ukraine until at least March 31st, 2022. Our goal with this small action is to show our support for those directly and indirectly affected by the situation taking place in the country, with the aim that not only we can help to keep communication alive to the region but most importantly to also spark a bit of hope in these very difficult times.
Extra light? No extra light?
Hello folks. Can you tell me, please, your opinion about whether or not I need extra light for my lecture cam? Continue reading “Extra light? No extra light?”
Yet more innumeracy in the popular press
What’s wrong with this sentence in this January 14, 2022 news story?
The $180 million solar farm will produce enough energy to supply the equivalent of more than 36,000 average households in the state annually, and it will provide around $54 million to local landowners.
Just like sentences that I blogged about on December 4, 2021, this sentence has a mistake that jumps off the page. Actually, two mistakes that jump off the page. Continue reading “Yet more innumeracy in the popular press”

What the rolling electrical blackouts in the mountains of Colorado on December 30th were all about
It turns out that the rolling electrical blackouts in the mountains of Colorado on December 30, which were a consequence of the devastating Marshall wildfire in Boulder Country, Colorado, were about the gas company avoiding having to relight pilot lights!
If there is anything that the gas company hates doing, it is having to send out workers to go from door to door to relight everybody’s pilot lights. Continue reading “What the rolling electrical blackouts in the mountains of Colorado on December 30th were all about”
