this article is on the options book not on cash equities. By the way, all exchanges still today run dozens if not hundreds of both, linux and windows servers for all kinds of tasks. Regarding its central matching engine for stocks I still like to see contrary evidence that it does not run on Windows Server. It may be that they switched over to linux in which case I happily admit I was wrong in saying that it today still runs on Windows, but the article I first posted clearly points to the fact that Nasdaq ran its central matching engine up until 2013 (and potentially longer) on Windows Server. Even several Nasdaq management officers pointed to Windows Servers as the reason for the outages at that time in order to divert attention away from other potential issues. That was word by word described in the article I posted, and a statement that that engine ran on Windows Server was explicitly mentioned, that article dated late 2013.
In the same way that you will need to pay for many Facebook privileges in 5 years which are all free today. Simple, you get the love-free-crowd (which is 90% of the world's population) to lock themselves into a standard and then you fork and charge for the content that is continued to be developed. Those who don't pay will rely on not-further-maintained versions.
NASDAQ explicitly uses the INET platform, there is no more NASDAQ platform, it was completely dumped, as claimed by NASDAQ itself, you're talking about your own fantasies. And the outages were related to the legacy SIP system, which was intentionally allowed to stagnate, nothing to do with their instinet platform, which was fine for the duration. You have not shown a single document proving nasdaq to use windows for its matching system or its core trading application, other than the garbage SIP. The head of NASDAQ technologies even claimed that the NASDAQ ran on linux, according to the article, along with all the other articles, mentioning NASDAQ and INET and even articles mentioning NASDAQ's switch to instinet. So, the burden of proof is on you to prove that NASDAQ uses windows for its matching system, given that NASDAQ ITSELF claims to have dumped its legacy system, for instinet INET, which runs on linux. There is really nothing more to be said here too.
stop spreading wrong information. You several times purposely falsified information and also changed intentionally what I said. Nasdaq runs multiple servers with different OSs for various data feeds, index calculations and dissemination, its order matching books for options, equities, and other products. For the records: NONE of your cited articles contains a single claim that their stock central matching engine runs on Linux. NONE. So, provide evidence or maybe its better to shut up? (I did provide evidence that Nasdaq until 2013 ran their equities central matching engine on Windows Server. )
Given your idiocy, you showed an article that demonstrated the SIP system, not the matching system, completely different technologies. Go sort through your own spam, and you'll just find another article relating to the deprecated SIP, LOL. You don't need to be running 3 threads on the same topic to post everything multiple times, only to show that you don't know what you're talking about, repeatedly. Especially, after you said that you would not post again.
That guy reminds me of the hftvol guy, exact same spelling of ".Net" and occasionally switching between proper punctuation and lower case leading character, the exact same arguments (something about Stackoverflow tags being the definitive proof that C# is the best programming language in the world - doesn't that mean that there's just much fewer proficient developers using C#?) and zealously steering a thread off-topic to defend MSFT and C# at the expense of reason and fact.
It is quite possible that he is paid Corporate or Gov't troll. Definitely he acts like one trying to discredit participants, hijack threads and frustrate readers. Maybe it is time for him to change Id again (busted! no bonus!)
so now others are idiotic, because you cannot find the right article. By the way this was, as mentioned multiple times not an article on SIP and it was not up-to-date, meaning it was dated 2013 not from this year.So, take it for what its worth. BUT, this is not what this discussion is about, I mentioned Nasdaq as one of many examples where large amounts of data are equally well processed and served on Windows Server, not just Linux. So, for the sake of at least the rest of the community would you PLEASE either provide a clear evidence of your Nasdaq claim or else stop talking about it? I added my side of the factual backup and I owe you nothing, so relax, take a deep breath and let's focus on this discussion. What does Linux offer you that Windows does not? Can you at least answer this question or are you not capable of meaningful participation>?
