bug in kdb2.7,file processing

bug in kdb2.7,file processing

I have a text file that contains data in the form
“TESS” NOTE, OPTN TEN
when I read the data from the file It is read as
TESS” NOTE, OPTN TEN
The double quotes in the beginning are removed

I read the file using the below command
table1: flip `acct`accountStatus`fullname!(“SSS”;”|”) 0:`:outdata1.dt

select fullname from table1 where acct=`0720002C
fullname
———————
TESS” NOTE, OPTN TEN

Can someone suggest a workaround?

 

==

Recent versions of q use Excel rules for escaping quotes and commas, but only in a 0: with comma as a separator, and only for fields parsed as string (“*”).

Ninja Trader 7 is junk. Full of bugs!! I removed it

Ninja Trader 7 is junk. Full of bugs!! I removed it
I cannot even display a basic chart after connecting with Yahoo. What gives? It sounds like I am not the only one with this problem nor do I have the patience to figure it out. I am downgrading to Ninja Trader 6.5.
An why do i get this message at start up? These sort of things are not encouraging.

Zen-Fire has informed us that on Wednesday June 29th, 2011 they will be retiring the connection points used in NinjaTrader 6.5. We don’t expect this change to impact NinjaTrader 7 users however, in the event that on or after this date you are unable to connect using NinjaTrader 7.0.1000.5 or later, please take the following action to try and remedy your situation.

* Start NinjaTrader 7
* Go to the menu Tools > Account Connections
* Remove your Zen-Fire connection
* Re-create your Zen-Fire connection
* Try and connect

Please let us know should you have any questions.

Regards,
NinjaTrader Customer Service

Update: I have confirmed on two different Windows versions of XP and 7 with same problem. Ninja 6.5 seems ok on the charting front.

Is there a bug with Ubuntu 10.X and VMWARE 7? ActiveQuant does not work on Windows 7 Eclipse?

Is there a bug with Ubuntu 10.X and VMWARE 7? ActiveQuant does not work on Windows 8 Eclipse?

I spent days trying to figure this out. It seems there is a strange bug with VMWare 7 and Ubuntu Desktop 10.x as being the guest. Everything will install fine with no issue. Once complete, I cannot type anything in my Ubuntu Desktop 10.x guest environment. I thought it was a fluke so I reinstalled twice but still had the same symptom. I wanted to verify that was the not the case with Windows Server 2003 as being guest. I even installed both Debian and CentOS 5 as being the guest. I had no issue with any of these guest operating systems which was kind of strange.

Well I can somehow verify there is an issue somehow but I cannot explain it nor did I not diagnose. I got better things to do than trying to figure out strange thing like this. I am only reporting it.

My resolution was pretty simple. I decided to install Ubuntu Server 9.x which appears to have the resolve typing issue. I then installed the Gnome graphic user interface on top of the Ubuntu Server edition with no issues. I will report that it really slows down so maybe that might not be wise. Anyhow, everything seems to run ok. Again, don’t ask? If someone can explain this in my comments sections that would be highly appreciated.

Now that brings me to my next question. As for Active Quant which is explained on setting up an Eclipse environment at:
http://www.activequant.org/wiki/aqt-env-docs
There was a strange warning I got once I built the Maven dependencies. This happened on Windows 7 but I moved ahead with the above environment with Ubuntu, It seems to work ok to. Is there a strange bug going on within Windows 7? Or at least with the required Windows Eclipse version? Comment your experiences below.

Did I discover a crazy (un)known bug within Marketcetera?

Call me crazy but Marketcetera might have a bug that would be deadly. As I ran their sample VWAP strategy within Photon, it seems I stopped it but the strategy kept running in my Order Routing Server. Thankfully, I was running against the Bogus feed but it seems that the Order Routing Server kept running the running the strategy until I broke it with Control C. Yikes that kind of looks scary. I am also using Marketcetera 1.5 for Windows. I wonder if this is a bug or just some one off wonky issue.
