    IB Suggestions & Improvements

    Again, the latest TWS Unix release is not up to date. The download page shows the latest version as June 16, but the actual downloaded jar is: Build 860.8, Jun 13, 2006 11:24:36 AM This would be no big deal except for the fact that for reasons unknown the previous realease (Jun 13th) will...

    I did it!...I just configured and ordered a Athlon Dual Core from CyberPowerSystems

    Yes 1 + 1 != 2, but 1 + 1 == 2 - a bit Where 'a bit' has to do with bus contention, memory contention and so forth. The size of the 'bit' depends on system architecture which is why Opteron with hyperchannel beats Xeon in multi CPU configurations. It is simply not true that the...

    I did it!...I just configured and ordered a Athlon Dual Core from CyberPowerSystems

    Sorry, this is incorrect and out of date. You are referring to so called 'green threads' that some Java VMs used in Linux implementations a few years ago. As far as I know all current Java VMs use native (ie kernel) threads - certainly on Linux and Solaris. I cannot imagine that Sun would do it...

    I did it!...I just configured and ordered a Athlon Dual Core from CyberPowerSystems

    I dunno, but I would suggest that there is little to be gained from doing such a thing. There has been 40 - 50 years of work that has been put into the design of operating system scheduling algorithms and probably 20 years or more for scheduling on multiple CPU machines. Statically assigning...

    ip address

    Correct. A DHCP server may choose to always map a MAC address to the same IP address if it wishes.

    Which came first the chart or the tape?

    I think this chart is somewhat interesting, and illustrates a fundamental behavior of the DOM in SIFs. It is todays KOSPI futures taken from IB data feed with bars 75 ticks wide (IB ticks - not necessarily trades). Main chart has a volume profile overlay. The first subchart is built from the DOM...

    Just wanted to say Hi

    valdair, I'm thinking of giving Opentick a try with the Java API. Could you elaborate on your issues with Opentick. Presumably you are using it with your own code with C#. Which exchanges and were the problems with L1, L2 or historical data ? How is the timeliness of the real time feed and...

    IB compatable platforms: Opinions??

    Most likely: 1. You are running out of memory. The pauses are caused by the operating system swapping memory pages to and from the swap file. Even though you have 2 gig installed, you might have lots of other legitimate things running or lots of malware on the machine. Make sure the machine...

    Two dual video cards

    I'm not advocating anything in particular, however I will say this. I have both Matrox G200 MMS PCI and Nvidia NVS 280 AGP in a machine. I run Linux and use my own charting software written in Java. I have run some benchmarks using this charting software. The Nivida card is much more than twice...

    Two dual video cards

    AGP is faster than PCI. PCI-E is faster than AGP. PCI-E is also general purpose, not just for graphics cards.

    Run a traceroute. It will show at what point your connection requests are failing.

    futures questions

    Enough of your position(s) will be liquidated immediately to bring you within the margin requirements. There is no margin call, but the liquidation will show on TWS. You can designate a 'liquidate last' position if you have multiple positions. 'Slippage' will depend on the instrument - expect...

    creation of the universe

    What is your point. Of course there are mistakes, wrong paths and the occasional fraud in science as in any human activity. However in broad sweep of history, science delivers the goods. You wouldn't be posting on ET without it. Blind faith in creationism and the reactionary attacks on science...

    creation of the universe

    What a load of reactionary regressive utter nonsense. You suggest there is some sort of conspiracy by scientists to perpetate some giant fraud on the rest of us. And whats more, the Catholic church is in on the conspiracy too. Well, answer me this. Where would we be without science, engineering...

    best language for quantiative finance? C, D, Fortran,python etc.

    I believe that what segv was referring to in the original post was *guaranteed* performance not necessarily fast performance. Languages that have garbage collection such as Java and Python cannot guarantee response times because the application code cannot control when the garbage collector is...

    best language for quantiative finance? C, D, Fortran,python etc.

    Hmmmm, I don't really fully agree with this. Sure, a capable person will pick up the language itself quickly, but these days it's not just the language itself. It's also about the whole framework and APIs and good practices in using the framework(s). I defy anybody, no matter how good a C++...

    Myth. Java is much faster than Ruby, Python and all other scripting languages.
