I really wanted to like Typst. No more latex would be fantastic. Decided to use it for a project, and had to give up and return to latex, just too many corner cases. Both things it…

I have European debit cards. They get rejected in many Albert Heijn when Dutch cards (debit and credit) are taken. Jumbo takes foreign cards. Jumbo gets my (and a lot of my colleag…

I agree. But plenty of Dutch vendor only accept Dutch mastercards and not foreign. The fee s the same. WHY? And foreigners can't get IDEAL or Dutch mastercards. I have gotten used …

One reason to like the visa mastercard duopoly. They work everywhere. I go to the Netherlands a lot for work, and it is a real pain as they have their own payment system, IDEAL, on…

AMEX unusable in Europe? Hardly. I payed for my dentist Friday with it, both supermarket and lunch today, and all Amazon, etc. Some vendors dont take it, but in my European country…

I much prefer parallel in R with mclapply() to the Julia implementation of parallel. One of the few areas where I prefer R to julia (other being R data.tables to julia dataframes)

I think that is exactly what is happening. Most of my code is much much faster in Julia, and the code is nicer. But R has its moments. Which is good since this particular app has 3…

Great idea, I do lurk there, just might do that next time I look at the code. My hunch is that simd is the low hanging fruit julia brings. But, and I am not an expert, both might e…

No, its 4 lines of code. I just benchmarked for myself. All it is for 2 vectors x and y of average length 50, and 5 parameters, with exponential, addition, and multiplication, and …

no, the function it calls is pure R and that is where the the code spends all its time.

I used to think so, but I have a function that gets called about a billion times each and every day as new data comes in, and and takes about 0.01 seconds to evaluate (optimizaiton…

Well I exported to ps this morning, since I used the pstricks package in latex. It is the best way I have seen to make diagrams with code, which can be very convenient. so python t…

I disagree, there are at least 2 reasons why eps can be better. a) you can exactly match the fonts in an eps figure to a latex file, which will look much better. b) you can use \ps…

yes, the book Ultra-Processed People https://www.nytimes.com/2023/07/07/books/review/ultra-proces... does that quite well.

Can believe that, but there is more to such additives than cancer. The book Ultra-Processed People https://www.nytimes.com/2023/07/07/books/review/ultra-proces... makes clear the d…

The demographic most likely to fall for scams is the 20 year old. So. no.

Its doomed to failure. Latex is horrible but makes beautiful documents and the relevant world either uses latex or Mircosoft Office. Why use anything else? Latex lives by the commu…

I have to disagree to "arguably not a very good fit, such as for presentation slides." I have to make regular work presentations with a lot of math. There are two choices: Powerpoi…

It is easy to say this doesn’t matter, and personally, I couldn’t care less which is used. However, professionally, I have twice in the past two months had a deal with text that wa…

I just hired a R engineer, so not that tiny. For a data science job with a lot of stats and math. R still beats Python for stats/data science programing. In my market, R people hav…

Last time I tried Octave it was several times slower than Matlab. Why use Octave instead of R, Python, or Julia? There is nothing Octave/Matlab can do that they can't. And anybody …

No. This week, the treasuries and other assets in capital are effectively cash equivalents.

You are conflating two things. Reserve requirements are not same as capital. And there is a modern capital requirement, as per Basel III, in effect since 2022. Capital historically…
