Via mono. If that's true... that would be an interesting news for the project (not because of the bug itself of course...).

  If the LSE were using F# we'd have heard a lot more about it already. For instance, from Microsoft.
  - viraptor 16y ago
    Maybe not if they were using F# on mono. Their PR would have to work very hard to put this in a way that doesn't say "LSE is using our language on a foreign platform using a completely alternative implementation, which has nothing to do with us apart some ECMA specs - and they're still successful without MS involvement. Yes, we just confirmed that you can trust your highly critical .NET environment to the alternative versions of runtime."

      OK, I wouldn't expect an official press release like this from Microsoft head office. But the team in Microsoft Research are (a) keen to promote their language (people like Don and Brian often help early adopters personally) and (b) supportive of Mono (they've always released a .zip file for Mono at the same time as their Windows installers).

      They have publicly stated that the system is written in C++ on Suse Linux. http://www.computerworlduk.com/news/open-source/3260727/london-stock-exchange-in-historic-linux-go-live/# http://www.computerworlduk.com/news/open-source/3260727/lond...

        I wouldn't believe 100% in those statements.
        IDisposableHero 16y ago
        True enough. If the statement turns out to be not entirely correct, that would be news. I suspect that if there is any F# code, it's in a 3rd party system that talks to the stock exchange. There are lots of those due to the nature of an exchange, though they should all talk over the standard FIX protocol.

        They systematically cover the problems and have zero transparency. Never a post-mortem. Like back in January.

  using a immature language (f#) over unproved software stack for an international multi billion dollar low latency transactions when there are dozens of proven highly stable functional alternatives that run well on a linux platform? I can hardly believe it

    That's modern enterprise computing for you.
  - IDisposableHero 16y ago
    I don't believe it at all. Mainly because of the public statements that the new LSE trading system was written in C++. On the other hand, it has to integrate with lots of enternal trading systems, one of which could easily be written in F#.

I doubt they'd be using Mono - if it really is an F# issue it maybe indicates it's a failure in some of the legacy system they are replacing.
- IDisposableHero 16y ago
  As far as I know, the previous system didn't use F#. "written in C#" http://www.computerworlduk.com/news/open-source/3260727/london-stock-exchange-in-historic-linux-go-live/# http://www.computerworlduk.com/news/open-source/3260727/lond...
