Texas Instruments Datasheets

I was watching The Differential Pair Becomes an Op-Amp – Transistors 101, episode 18 and they mentioned this datasheet: https://ti.com/lit/ds/symlink/lm358.pdf. That URL looks very hacker friendly to me, if you know what you’re looking for you can probably guess the URL! I haven’t tried this in anger yet, this is just a note for Future John.

Homework

This is a part of the homework feature of my blog, which is an ongoing conversation with my mate S.F.

Hey mate. Lovely to see you again, as always.

I have a note here about Milo but I’m not sure why.

There is a rumor that the story of Snow White and the Seven Dwarfs is about cocaine addiction, particularly that the Seven Dwarfs represent the various stages. But Snopes says this theory is bunk.

Two authors Strunk & White wrote a book called The Elements of Style which is a style guide for formal grammar used in American English writing. Famously they said “let every word tell”.

The phone you gave me I named ‘skadi’ after the Norse goddess Skaði.

According to John Cleese in his hilarious letter Something of a Retraction: Cleese letter to the U.S., French fries aren’t French, they’re Belgian.

I heard a rumour that DeepSeek says there are three r’s in “strawberry” but I can’t find a corroborating source.

Penny Arcade is great. I mentioned this one: Dirty One.

In Laws and Sausages the structure of the United States of America is explained in a comic format.

In Death of a Salesman there is a famous quote “A salesman is got to dream. It comes with the territory.”

Tribal not racist.

I think all you need for subjective experience is one or more sensors. Both consciousness and self-awareness are different to that. Although they probably do entail subjective experience too.

I should have a promotions policy on my website. Thanks for the suggestion. I will look into this.

There is a famous RFC: Key words for use in RFCs to Indicate Requirement Levels. This, for instance, defines what the word “should” should mean.

The seven check marks are elements of white privilege, given as:

  1. male
  2. white
  3. heterosexual
  4. at least one highly educated or wealthy parent
  5. at least one parent born in the Netherlands
  6. a VWO diploma (preparatory scientific education)
  7. and a diploma from the University

In Outliers the author Malcolm Gladwell comes to the conclusion that success is mostly luck. In the same book Gladwell says that to attain mastery the a subject needs to be actively studied for 10,000 hours.

In Magic Words and How to Use Them the author explains how you can use uncompromising positivity to craft the life you want. Seemed to work for me, if you’re positive about people they seem to magically be positive back.

The Old New Thing is a blog from Raymond Chen, a long time programmer from Microsoft who had a lot to do with Windows.

I mentioned that Alan Kay worked for both Atari and Apple.

The famous quote “Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.” is from Andrew S. Tanenbaum.

Asleep From Day by The Chemical Brothers.

Why You Will Marry the Wrong Person from Alain de Botton.

Before you speak let your words pass through three gates:

  1. is it true?
  2. is it necessary?
  3. is it kind?

New Book Teardown #6: God Created the Integers (2005) | Learning Electronics In The Lab With Jay Jay

This post is part of my video blog and you can find more information about this video over here.

In this video I take a look at God Created the Integers edited by Stephen Hawking and published in 2005.

Hawking’s other book which I mention in this video is On The Shoulders Of Giants.

I am sorry that my pronunciation of European names is kind of terrible. While working through the book I made some notes on my wiki about pronouncing various names: God Created the Integers.

At 12 hours (the YouTube maximum video length) this is my longest video so far! If you do watch the whole thing through to the end, you are my type of person, so please do let me know! :)

Homework

This is a part of the homework feature of my blog, which is an ongoing conversation with my mate S.F.

Hey mate. Lovely to see you again, as always.

First, two things from last time which I forgot to write up:

I mentioned Veritasium which is a video blog of interest.

I have a note here that says “ASI”. And that’s all it says. Not sure what that was about?

I did consider writing my response to Mark Fisher‘s work Capitalist Realism (which is available on the web here), but in researching him and his work this evening I have learned that he died by suicide in 2017. I think suicide is the worst thing ever and I can’t bring myself to write something which tears strips off people who are no longer here to respond. (I intend to read Mark’s PhD thesis Flatline constructs: Gothic materialism and cybernetic theory-fiction.)

You mentioned Pick of the Litter, noting that dogs are trained to sometimes ignore the command of their master, particularly when it wouldn’t be safe.

One good thing about arguments with friends is that there is always time to pee.

Norvig’s Law: Any technology that surpasses 50% penetration will never double again (in any number of months).

This marketing dude Rory Sutherland is actually quite impressive. I hadn’t expected as much from someone in advertising! He has given a number of TED talks and there are many interviews with him on YouTube.

The documentary about the 2008 financial crisis that I mentioned was Inside Job. Not to be confused with the TV series with the same name (which is excellent, by the way).

My favorite philosopher of the day is Iain McGilchrist. I suspect my own beliefs and preferences diverge from those of McGilchrist but I do really enjoy his thought. I have watched a number of interviews with Iain McGilchrist. He has written a number of books, a few of which I have purchased and intend to read: The Matter With Things: Our Brains, Our Delusions and the Unmaking of the World, The Master and His Emissary: The Divided Brain and the Making of the Western World, and The Divided Brain and the Search for Meaning.

The book Thinking, Fast and Slow by psychologist Daniel Kahneman demarcates two systems of thinking: one fast and automatic, the other slow and deliberative.

The quotation “the stupid are cocksure, while the intelligent are full of doubt” is variously attributed (including to Bertrand Russell).

Check out Mr Inbetween, it’s really excellent!

Love you my brother, see you on Christmas Day! <3

Books by Bill Inmon

This is a note for Future John.

I am reading Fundamentals of Data Engineering which says that beside Ralph Kimball, Bill Inmon had a lot to do with data warehousing in the early days. I’m going to try and read a few of his books, many of which are available in Kindle (and Audible) format from Amazon.

What is elliptic curve cryptography?

The following quotation is taken from Elliptic Curve Cryptography for Developers.

What is elliptic curve cryptography?

First, there are no ellipses. Second, there are no curves. So why is it called an “elliptic curve”? The primary reason is history. Performing integrals of the elliptical orbits of planets gave rise to formulas labeled elliptic curves. These formulas were then used in other areas of mathematics, and the label stuck.

The areas of mathematics used in public key cryptography involve number theory (the properties of integers), combinatorics (the study of counting), and finite fields (sets with finite objects and specific rules). Elliptic curves are used in just about every area of mathematics. This makes studying elliptic curve math very difficult because it is hard to determine what you really need to know and what is just really interesting.

For example, elliptic curves have been used for factoring numbers and solving Fermat’s Last Theorem. In chapter 3, I explain how elliptic curves on the complex plane are used to understand elliptic curves over finite fields. It’s all interesting but not necessarily applicable to cryptography.

USB on Hackaday

Some articles about USB on Hackaday recently:

Rory Sutherland reading list

I just watched this presentation from Rory Sutherland: Rory Sutherland: Want Fewer People to go to A&E? Change the Name | Health | WIRED.

At the end he provides this reading list:

I don’t have the time (or money) to read all of those books, the book I picked to read was Nudge.
