   I once heard the same about the FT and tried it. In general, it was a pleasant experience and they not only covered topics in a neutral way but also allowed commentaries from different viewpoints. However, I didn't extend my subscripti

   The papers are written by Brian Beckman as you have found out by yourself certainly. However, this doesn't answer my question.

   As those papers are hosted on vixra.org, how credible is the content? Has somebody with deeper knowledge on the subject had a look into it?

   Has somebody here experience with Jd and could comment on the status or the performance? Thanks!

   The real one got adopted when he was four years old and his new parents "raised him as their own." He found out about the adoption a long time later. Therefore, it is safe to assume that he also had a different name.

    Spoiler: The real one was adopted and met Johanna later. Source: The story can be found on Kindle Singles, but the BBC article contains basically everything interesting already.

    I also remember them being called "software machine gun" by Duntemann in his assembly book. Using REP STOSW could save you 5 instructions.

    Also, if you know a little bit about finance and are interested in Ed Thorp, read his papers. For example, https://books.google.de/books?id=uOPa9XtzoJ4C&lpg=PA181&ots=... should give you a feeling of how his hedge f

    You are mixing up some facts. By taking your number of 120.000,- EUR salary before tax and entering it into the tax calculator of the Ministry of Finance [0], I get about the same number for the final salary. Therefore, the employee had to

    The 50% tax rate is a marginal tax rate. If you would earn e.g. 100.000 EUR per year, you would pay about 39% (tax plus social security). 200.000 EUR per year -> 42% (tax plus social security) totally. This calculation was done for an em

    Insurance companies develop HPC stochastic financial projection models in C++. I have seen approaches using R or Python, but they couldn't give the performance necessary for getting results in reasonable time.

    Who else is quoted in the article with an opinion similar to Ted Ligety's? Also, I don't want to insinuate bad motives, but it should be pointed out that he is a co-founder of slytech ( http://slytechprotection.com/

    I would rather suggest to read Popper's Logic of Scientific Discovery or works of Lakatos before reading Feyerabend's Against Method. Feyerabend was a former assistant of Popper and mainly criticised his methodological views.

    I would be happy to use languages like J/K or Julia for our actuarial projection simulations instead of C++. However, despite quicker development times, a factor of 2 in the runtime for our stochastic projections would be terrible. Has
