The First Computer Bug

The First Computer Bug…

In 1945, Grace Murray Hopper was working on the Harvard University Mark II Aiken Relay Calculator. On the 9th of September, 1945, when the machine was experiencing problems, an investigation showed that there was a moth trapped between the points of Relay #70, in Panel F. The operators removed the moth and affixed it to the log. The entry reads: “First actual case of bug being found.”

Grace Murray Hopper, who lived from 1906-1992, found the first computer bug while working in a temporary World War I building at Harvard University on the Mark II computer where a moth had been beaten to death in the jaws of a relay. She glued it into the logbook of the computer and thereafter when the machine stops (frequently) they say that they are “debugging” the computer.

The very first bug still exists in the National Museum of American History of the Smithsonian Institution. The word bug and the concept of debugging had been used previously, perhaps by Edison, but this was probably the first verification that the concept applied to computers.

Google’s Role in Social Distancing

I thought this was interesting! Google is taking anonymized, aggregate data from Google Maps for public health officials to understand responses to social distancing guidance related to COVID-19.

Here is the data I pulled for the state of Minnesota. It looks like in general, 38% less people are travelling to work, 35% less people are travelling to grocery stores and pharmacies, and 58% less people are travelling to restaurants, cafes, and shopping centers. Rice County seems to be doing slightly worse at sheltering-in-place compared to the average in Minnesota, except in the travelling to work and parks categories.

The more you know!

Does a USB drive get heavier as you store more files on it?
Believe it or not, they get lighter. USB drives use Flash memory, which means the the ones and zeros of your data are stored on transistors. When you save data, a binary zero is set by charging the float gate of the transistor, and a binary one is set by removing the charge. To charge it, we add electrons, and the mass of each electron is 0.00000000000000000000000000091 grams. This means that an empty USB drive (which mostly holds zeros) weighs more than a full USB drive (which has ones and zeros). Add data, reduce the weight. However, you would need to weigh more USB drives than exist on the planet together at once before the difference in weight became easily measurable.

Not All is Doom and Gloom with COVID

All joking aside for once, if there’s one thing I can say about all this Coronavirus “craziness”, “pandemic”, “panic”, “crisis”, “precaution”, “stupidity” (pick the adjective you most relate to), it is this: People are forced to think out of the box for solutions to problems they never thought they’d encounter, and this is NOT A BAD THING! It shakes up the status quo and forces people out of their comfort zone.

People will have to educate themselves on using technology to get work done, instead of forcing mostly unnecessary (and potentially hazardous right now) in-person meetings.
Businesses owners will have to remain agile and adapt their business models on the fly. Especially now, as bars and restaurants are being forced to close. They have to. Otherwise they have no choice to close and layoff all their workers.

Yes, the stock markets are down. If you are on a long-term plan to retirement, it’s going to recover no problem. This is an opportunity, not a crisis. Make the best of the hand you’re dealt now!

Above all, don’t sweat the small stuff. So, you may need to use a fabric cloth instead of a paper towel. So you may have to meet a new neighbor to borrow a couple of eggs. The world survived many centuries without all the modern conveniences we take for granted now. Use it as a way to learn history, and use it as a way to learn something new.

Nearly nobody has framed this event as a positive one. Yet, with a slight change of mind, there can and will be good things that will come out of this that will help us, and will help the country grow stronger. Get ready for a wild ride guys! This is no doubt a story people will be able to tell their grandkids about. 😃

I’m a New Mac Owner!

I never thought the time would come, but I have to announce I’m a brand new Mac owner! Mind you, it’s not a new Mac, but I am a new owner! 😂

I received a Certificate of Special Congressional Recognition!

Wow! I received a Certificate of Special Congressional Recognition from our District’s Representative Jim Hagedorn for the “Hidden Gem” award I received from the Faribault Virtues Project. It was an honor to be recognized for some work I’ve done over the years preserving history in Faribault and Rice County. If we all pitched in and helped our community in one or two small ways, what a wonderful place our world could become!
