### How to model an opamp? (the implications on simulation)

This entry is part 4 of 13 in the series Analog modelling

It’s a question I always asked myself. Models in SPICE are usually for full models, or you can use a gain voltage gain as well. What are the implications of selecting one model over another for a real time model? Let’s go for the more complex model to the simplest ones.

### Book review: Too Much And Never Enough: How My Family Created the World’s Most Dangerous Man

Yet another book on Trump, but I liked the premise of this one, as it’s his own niece that wrote it. With a training as a psychologist, she can give a unique perspective on the guy, and het point of view is not the one of an angry betrayed Republican…

### Announcement: Audio TK 3.2.0

Audio ToolKit is finally updated to 3.2.0. The main changes for this release are mainly cleanup of the API and better C++17 support with variable defaulting.

### Book review: Why I’m No Longer Talking to White People About Race

It’s only logical to go on an read this book after Me and White Supremacy, as they are answering to each other, one about how to get rid of racism, and this one more on the history and the testimony on racism. It’s also the second book on #BlackLivesMatter that we shared in my fitness book club.

### Should I invert my matrix or not?

This entry is part 5 of 13 in the series Analog modelling

In almost all analog modeling algorithms, we solve a (non-)linear system they require at some point to solve $A x=y$, with given $A$ and $y$. Depending on the size of the matrix and its characteristics, computing an inverse can be costly and may incur numerical problems. Let’s tackle cost in this discussion.

### Book review: Me and White Supremacy: How to Recognise Your Privilege, Combat Racism and Change the World

Is it fair to say that this issue is quite current? My fitness book club had this book on their list since before the CrossFit scandal, so it’s fair to see that they were ahead of the curve on this one, and I’m proud to be part of the team.

Still, is being proud of what they did enough? What should I do more to tackle white supremacy?

### Book review: A Very Stable Genius: Donald J. Trump’s Testing of America

I started reading this book a few weeks ago, when Trump started the whole ObamaGate nonsense, and when he tried to flip the narrative on what happened with Flynn. As I was reading what happened 3 years ago, it was astonishing to see how manipulative this president is.

This is clearly a political book, and this is not something that I usually review, but sometimes you need to wake up and take position.

### Book review: Masters Of Doom: How Two Guys Created an Empire and Transformed Pop Culture

Did you ever wonder what happened at id Software when they created their famous first games? This book sheds a novelized light on the life in id Software and the main characters that made happened, focused on the relationship between the two Johns.

### Book review: Beat the Reaper

For this week’s book club, I was supposed to read Normal People, which is supposed to be an acclaimed book. Frankly, I couldn’t read it. The style is horrendous and unreadable (and I managed to read the Hunger Games books which were ranked at the lowest in my opinion). A few reasons are the fact that it’s a first person-present tense book, which I always fail to dive in. By definition, these books don’t allow me to immerse myself in their environment. Then the other reason is that when the book start, in the first few pages, you don’t get any information, any goal to go on reading.

So instead, I turned myself to an older book I read when I came in the UK (I think), Beat the Reaper.

### Book review: 10% Human: How Your Body’s Microbes Hold the Key to Health and Happiness

As some of you may have noticed, I’m quite interested in medicine, with my PhD and some recent reads like the French equivalent of this book (Le charme discret des intestins) or Book review: Why We Sleep. So when our book club selected this book, I was thrilled.
