ResearchBuzz: FirehoseSearch Engine Roundtable: Google’s Mortgage Calculator Hasn’t Worked In A Week. “About a week ago, if you searched for mortgage related math questions in Google Search, Google stopped giving you the answer. Google first introduced its mortgage calculator features a decade ago but suddenly the features disappeared last weekend. I figured I’d give them several days before reporting on it but […]<a href="https://rbfirehose.com/2025/03/22/search-engine-roundtable-googles-mortgage-calculator-hasnt-worked-in-a-week/" class="" rel="nofollow noopener noreferrer" target="_blank">https://rbfirehose.com/2025/03/22/search-engine-roundtable-googles-mortgage-calculator-hasnt-worked-in-a-week/</a>

cthululemonThis little mechanical calculator is one of my favorite objects. It came to me with what turned out to be a fouled 10s pin retaining ring; it was a bear to take apart, ‘machine’ a new part, and reassemble. But it works!

Swede’s PhotographsGood morning, friends. 🌹🌹🌹9 April 2024When I was in high school, as I recall, we didn't have battery operated calculators. I'm not sure that they were a thing back then. Hmmm ... I need to look that up. ... Here's what I found out, the first battery operated portable calculator, the QT-8B was marketed by Sharp in mid-1970 (1). It was too large to be considered a pocket calculator and the cost was $495 (2), which is the equivalent of about $4K today. So, as you can imagine, we did all calculations by hand. There were slide rules and I suppose the abacus counts as well. There were mechanical calculators, and we were taught how to use them along with typewriters, in a Business Machines class."I am so old, I entered engineering school with a slide rule. And I left engineering school with a calculator. I can still use a slide rule but it's not a skill you especially need anymore". - Bill Nye<a href="https://universeodon.com/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photography</a> <a href="https://universeodon.com/tags/photographer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photographer</a> <a href="https://universeodon.com/tags/photographylovers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photographylovers</a> <a href="https://universeodon.com/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nature</a> <a href="https://universeodon.com/tags/morning" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#morning</a> <a href="https://universeodon.com/tags/calculators" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#calculators</a> <a href="https://universeodon.com/tags/flower" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#flower</a> <a href="https://universeodon.com/tags/rose" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rose</a>

Thilo, EE 🤘🏼🇪🇺⚛🎗️Today I learned about introductory posts here. So I'll add this in. I'm an electrical engineer with a focus on transmission and distribution (T&D).
