I grew up in the early years of personal computers and was a young adult in the early years of the web/internet, with most of my career in the age of mobile phones and wireless connectivity. I’ve never had to run a company without having a computer-based spreadsheet for computations. I remember adding machines with paper tapes, but never owned one. And until this week had never seen and NCR...
While reading about nostalgic computing on the Chip Letter, I came across the following picture of hand-written assembly code for the IBM S/360. What caught my eye wasn’t the paper spreadsheet, but the ah ha moment of clarity explaining why assemblers assume anything in the first column of text is a label, i.e. why assemblers require mnemonics to be prefixed by a space or tab. I’m an...
GDP is not the best of measures but it is what we use to meaure economies. Globally, (in 2023) that totals more than $100 trillion. My post-pandemic work is primarily focused on the bottom left slice of this big pie, in Africa. That continent’s GDP is more than $3 trillion, and even 1 trillion dollars is a lot of dollars, but in comparison to the rest of the world, is tiny. Smaller still as...
There are so many lessons in startups, startup investing, and technology adoption that come from looking back a few decades. For example, I’m out of the 1970s nostalgic computing rabbit hole, but that journey has subsequently led to reviewing the technological progress of the late 1900s and early 2000s. This week, that was the rise of the RISC-based CPU, which was then obviously going to...
The buzzword of 2024 is “AI” and like social, mobile, cloud, fintech, and blockchain, every startup is claiming to have it and every big startup fundraising is claiming to expand what can be done with it. Or in short, we’ve been here before. A Grand Unified Theory of the AI Hype Cycle does a very good job explaining how this will play out in 13 steps, and how it already played...
I’ve never been able to explain why I have so hard of a time believing consultants. What is it about their role that make their conclusions so often so wrong? None other than Steve Jobs explains… in less than two minutes.
“I don’t think there is anything inherently evil in consulting” … but “You never really taste it.” – Steve Jobs
Who invented double entry accounting? The ubiquitous system of general ledgers, income statements, balance sheets, and cashflow statements found throughout businesses and quite a lot of households? This is yet-another of those concept so taken for granted that they seem to have been around “forever”, but thanks to Double Entry: How the Merchants of Venice Created Modern Finance by...
Many of the everyday details in The Work of the Stock Market told in between the history facts are often just as interesting as the history itself. Case in point, if you read the history of time zones, it seemed like the standardization was complete in the U.S. and Europe by the end of the 1800s. Yet in 1922… The difference in time between London and New York is four minutes and one second...
The standard structure for private equity funds (and venture capital funds) is “2&20”, as in a 2% management fee (±1%) and 20% (±10%) of the profits, a.k.a. “carried interest“. Why 20% of the profits?
Henry Kravis of KKR explains below, starting at 6:00. TL;DR: Necessity, as he and his partners had no capital to put at risk.
My refrigerator died last week, and with that, my family and I lived with an “ice box” in its place, using frozen bottles of water as the source of cooling until today, when the new refrigerator was installed. Refrigeration is a service billions of us take for granted. Living without it for a week helps one ungrant that taking (or however that is supposed to be phrased). All of this...
