  • bash script to delete old deployments

    - by benjwarner
    I have a directory where our deployments go. A deployment (which is itself a directory) is named in the format: <application-name>_<date> e.g. trader-gui_20091102 There are multiple applications deployed to this same parent directory, so the contents of the parent directory might look something like this: trader-gui_20091106 trader-gui_20091102 trader-gui_20091010 simulator_20091106 simulator_20091102 simulator_20090910 simulator_20090820 I want to write a bash script to clean out all deployments except for the most current of each application. (The most current denoted by the date in the name of the deployment). So running the bash script on the above parent directory would leave: trader-gui_20091106 simulator_20091106 Any help would be appreciated.

  • Is there a COMPLETE tutorial for upgrading for dummies?

    - by Windwood Trader
    I have tried upgrading in the past with zero success doing a backup of stuff and futilely attempting to enter my stuff into the new version. My email accounts and folders, my bookmarks and web browser info and of course my photos. In the past I have received messages that the back up files were done using version XXX and cannot be read by the new system, as an example. I need a hand-holding tutorial to go from 11.04 to 12.10. What are the actual step by step mechanics? Frustrated Non-Geek

  • How to use a DHT for a social trading environment

    - by Lirik
    I'm trying to understand if a DHT can be used to solve a problem I'm working on: I have a trading environment where professional option traders can get an increase in their risk limit by requesting that fellow traders lend them some of their risk limit. The lending trader will can either search for traders with certain risk parameters which are part of every trader's profile, i.e. Greeks, or the lending trader can subscribe to requests from certain traders. I want this environment to be scalable and decentralized, but I don't know how traders can search for specific profile parameters when the data is contained in a DHT. Could anybody explain how this can be done?

  • Send post data while opening SSE connection

    - by Prosto Trader
    I'm trying to establish SSE connection and do some long-taking actions on server-side, informing user about how it goes through SSE events. Actually, I don't understand how would I send some data along with new connection. I have to combine regular ajax with new EventSource or there is a way to transfer post data inside that event? Here is what I have so far, and I need to send pretty big JSON with the request. Is it possible or the only way to send data is GET? var source = new EventSource('/terminal/ajax-put-packet-trade-order/');

  • Most efficient way to connect an ISAPI Dll to a windows service

    - by Mike Trader
    I am writing a custom server for a client. They want scalability so I must use a thread pool and probably I/O completion port to regulate it. The main requirement is that a windows service manage the HTTP requests for a number of reasons. An example of one would be that a client session spans many requests and continuity must be maintained. Another would be that the ISAPI Dll will be in the IIS address space and so it's code will be lean and very carefully implemented. The extensive processing in the Windows service may get unruly for the duration of the lengthy development. If the service crashes it will not take out IIS. Anyway, the remaining decision is how to have these two processes communicate. We have talked about pipes, tcp, global memory and even a single pipe with multiplexed data ala FastCGI. Would love to hear anyones experience with a decision like this.

  • EXEC() syntax error using ODBC

    - by Mike Trader
    I have written a little ETL application that I wish to run a few lines of TSQL from. If i enter a simple query like "SELECT * FROM MyTable" everything is fine. All single line commands run as expected. A multiline query like this is also fine: DECLARE @TableName NVARCHAR(MAX) set @TableName = 'MyTable' EXECute ( 'DROP TABLE '+ @TableName ) Howevery when I try and run: DECLARE @TableName NVARCHAR(MAX) OPEN Tables FETCH NEXT FROM Tables INTO @TableName WHILE @@FETCH_STATUS = 0 BEGIN EXEC( 'DROP TABLE ' + @TableName ) FETCH NEXT FROM Tables INTO @TableName END I get a syntax error after TABLE in the EXEC() call. I have spent 6 hours trying to figure this out thinking perhaps I need to escape the single quote or something. I just cannot see the problem. A set of fresh eyes would be appreciated.

  • How to hide a program that is running on a virtual machine?

    - by Femto Trader
    Some softwares contain tests to see if they are running on a virtual machine. It's very unpleasant to see alert messages such as "Sorry, this application cannot run under a Virtual Machine." and have your software stopped! There is a lot of legal reasons to override such tests. Moreover such limitations are (most of the time) not written in User License Agreement. So... how to hide a program that is running on a virtual machine? I'm using a Virtual Private Server (VPS) with Hyper-V... I'm administrator of the Operating System (Windows 2003) installed on this VPS, not administrator of Hyper-V.

  • Windows Server 2008 - Setting Up DNS and Web Server (IIS) to host personal website?

    - by Car Trader
    Okay, I have a server, (Windows Server 2008 R2 to be more precise) and I have installed PHP, MySQL, phpMyAdmin, for web hosting purposes. I have set up a static ip address internally. I have installed the role DNS and Web Server (IIS) role. I now set up my forward looking zone as my chosen domain. I set up the nameservers as ns1.domain.co.uk with my IP address which I found from whatismyip.org. However, when I type my IP address, it times out with an error (Timeout Error). Am I doing something wrong? Am I missing something? Also I have seen that most websites have multiple nameservers, which are apparently mirror IP addresses which all redirect to one IP address. Also, I can locally connect using the IP address 192.168.0.8, however, I want to put my website online/live on the internet. Can anyone help me with this? -- Regards

  • Skype Raw API (NOT COM API) send message problem

    - by Mike Trader
    In converting this CONSOLE example to a full windows dialog implementation I have run into a very "simple problem". SendMessage() (line 283) is returning zero, GetLastError reveals 0x578 - Invalid window handle. http://read.pudn.com/downloads51/sourcecode/windows/multimedia/175678/msgapitest.cpp__.htm (https://developer.skype.com/Download/Sample...example_win.zip) C++ 2005 Studio express edition instructions http://forum.skype.com/index.php?showtopic=54549 The previous call using HWND_BROADCAST works and Skype replies as expected, so I know Skype is installed and working properly. The handle I use is the wParam value from the Skype Reply message, as in the code. This is non zero, but I am not sure if there is a way to test it other than with SendMessage. The compiled app from this C++ code example (see zip download) does actually work so I am stumped. I do encode the message with UTF8, and I create an instance of the COPYDATASTRUCT in my app, populate it then call SendMessage() with the COPYDATASTRUCT pointer in lparam. Skype does not respond nor does it obey. Am I missing something obvious here?

  • Batch Geocoding with Garmin Mapsource

    - by Mike Trader
    Please Note: I AM NOT LOOKING FOR AN ALTERNATIVE SOLUTION I lost track of this effort years ago but have need to geocode thousands of addresses nightly. I must use the very accurate database sitting on the machine, installed when the Nuvi map update installed Mapsource. When I contacted Garmin years ago, they expressed an interest in providing an API for this, but then I heard nothing and did not follow up. Their database is provided by navtec? I believe. Anyone have experience with that format? I posted on the Garmin Developer forum a while ago, but its a little lethargic over there :) Has anyone done this? Does anyone know how it might be done without an API; meaning database structure and calls? I'll take a solution in any language. Added: Garmin has expressed an interest in making this available to me. They just have not done it. I do not know the database format. I am NOT looking for an online solution or any other "alternative". This question is very specific. Contact Info: MikeTrader2 A T gmail D O T com Added: I offered a 400 pt bounty for this. Jeff Atwood then offered 400pts also. If you would like to see a solution to this, vote up the question and I will chase up Garmin and show there is interest in finally providing this. Please Note: I AM NOT LOOKING FOR AN ALTERNATIVE SOLUTION

  • Synchronizing reading and writing with synchronous NamedPipes

    - by Mike Trader
    A Named Pipe Server is created with hPipe = CreateNamedPipe( zPipePath, PIPE_ACCESS_DUPLEX, PIPE_TYPE_BYTE | PIPE_WAIT | PIPE_READMODE_BYTE, PIPE_UNLIMITED_INSTANCES, 8192, 8192, NMPWAIT_USE_DEFAULT_WAIT, NULL) Then we immediately call: ConnectNamedPipe( hPipe, BYVAL %NULL ) Which blocks until the client connects. Then we proceed directly to ReadFile( hPipe, ... The problem is that it takes the Client takes a finite amount of time to prepare and write all the fcgi request parameters. This has usually not completed before the Pipe Server performs its ReadFile(). The Read file operation thus finds no data in the pipe and the process fails. Is there a mechanism to tell when a Write() has occurred/finished after a client has connected to a NamedPipe? If I had control of the Client process, I could use a common Mutex, but I don't, and I really do not want to get into I/O completion ports just to solve this problem! I can of course use a simple timer to wait 60m/s or so which is usually plenty of time for the wrote to complete, but that is a horrible hack.

  • C++ Windows IOCP - HTTP POST data missing

    - by Mike Trader
    I have written a very simple IOCP HTTP server that works for the GET verb, but not POST. I create a socket and a listen thread in which accept() is waiting for a connection. When a client connects I call ioctlsocket() to unblock the socket then I associate the socket with IOCP and finally call WSARecv() to read the data. Some data is indeed read and when that has happened, IOCP wakes up a worker thread via GetQueuedCompletionStatus() and I recover the request data. I only ever get the request header when I POST from any browser. Any suggestions as to why? I am assuming the IOCP completes when ALL the data has arrived from TCP?

  • Different RegisterWindowMessage() names appear the same

    - by Mike Trader
    Using the C/C++ Windows API RegisterWindowMessage() I am using the name of the application as the message name. Next I call CreatMutex() using the same name so that I can tell if it already exists. If it does, I know this application is already running and not to launch a second instance of it. THis is the operation of my function Running() My confusion is over the message name. It seems that "AutoConvert.exe" and "AutoAppend.exe" are interpreted as the same name. Why?

  • Is CDS a valid analogy for pointers? [closed]

    - by Flinkman
    So.. bear with me. I just found an analogy to c++ pointers and CDS. This clip describes CDS(Credit Default Swaps). http://www.youtube.com/watch?v=KPNdYtrlgaU#t=120s "Here we know we have an instrument of a particular financial instrument that is demonstrably dangerous, it creates long chains of risk which are vulnerable to the failure of individual trader or market partipants, in that chain and these instruments in an affect permit the creation of vicious spirals. In which the CDS price interact with the bound price, the market price and you can have a downward spiral." What my ears are telling me: "Don't create dependences that will create long chains of crashing systems." Update: Trying to clarify with something that is closer to the readers. If I change the words: instrument = construct financial = language trader = object market partipants = c structs CDS price = uptime bound price = outcome market price = ROI(return on incestment) The quote become more understandable. Look: "Here we know we have construct of a particular language construct that is demonstrably dangerous, it creates long chains of risk which are vulnerable to the failure of individual object or structs in that chain and these system in an affect permit the creation of vicious spirals. In which the uptime interact with the outcome, the ROI and you can have a downward spiral."

  • Windows Azure End to End Examples

    - by BuckWoody
    I’m fascinated by the way people learn. I’m told there are several methods people use to understand new information, from reading to watching, from experiencing to exploring. Personally, I use multiple methods of learning when I encounter a new topic, usually starting with reading a bit about the concepts. I quickly want to put those into practice, however, especially in the technical realm. I immediately look for examples where I can start trying out the concepts. But I often want a “real” example – not just something that represents the concept, but something that is real-world, showing some feature I could actually use. And it’s no different with the Windows Azure platform – I like finding things I can do now, and actually use. So when I started learning Windows Azure, I of course began with the Windows Azure Training Kit – which has lots of examples and labs, presentations and so on. But from there, I wanted more examples I could learn from, and eventually teach others with. I was asked if I would write a few of those up, so here are the ones I use. CodePlex CodePlex is Microsoft’s version of an “Open Source” repository. Anyone can start a project, add code, documentation and more to it and make it available to the world, free of charge, using various licenses as they wish. Microsoft also uses this location for most of the examples we publish, and sample databases for SQL Server. If you search in CodePlex for “Azure”, you’ll come back with a list of projects that folks have posted, including those of us at Microsoft. The source code and documentation are there, so you can learn using actual examples of code that will do what you need. There’s everything from a simple table query to a full project that is sort of a “Corporate Dropbox” that uses Windows Azure Storage. The advantage is that this code is immediately usable. It’s searchable, and you can often find a complete solution to meet your needs. The disadvantage is that the code is pretty specific – it may not cover a huge project like you’re looking for. Also, depending on the author(s), you might not find the documentation level you want. Link: http://azureexamples.codeplex.com/site/search?query=Azure&ac=8    Tailspin Microsoft Patterns and Practices is a group here that does an amazing job at sharing standard ways of doing IT – from operations to coding. If you’re not familiar with this resource, make sure you read up on it. Long before I joined Microsoft I used their work in my daily job – saved a ton of time. It has resources not only for Windows Azure but other Microsoft software as well. The Patterns and Practices group also publishes full books – you can buy these, but many are also online for free. There’s an end-to-end example for Windows Azure using a company called “Tailspin”, and the work covers not only the code but the design of the full solution. If you really want to understand the thought that goes into a Platform-as-a-Service solution, this is an excellent resource. The advantages are that this is a book, it’s complete, and it includes a discussion of design decisions. The disadvantage is that it’s a little over a year old – and in “Cloud” years that’s a lot. So many things have changed, improved, and have been added that you need to treat this as a resource, but not the only one. Still, highly recommended. Link: http://msdn.microsoft.com/en-us/library/ff728592.aspx Azure Stock Trader Sometimes you need a mix of a CodePlex-style application, and a little more detail on how it was put together. And it would be great if you could actually play with the completed application, to see how it really functions on the actual platform. That’s the Azure Stock Trader application. There’s a place where you can read about the application, and then it’s been published to Windows Azure – the production platform – and you can use it, explore, and see how it performs. I use this application all the time to demonstrate Windows Azure, or a particular part of Windows Azure. The advantage is that this is an end-to-end application, and online as well. The disadvantage is that it takes a bit of self-learning to work through.  Links: Learn it: http://msdn.microsoft.com/en-us/netframework/bb499684 Use it: https://azurestocktrader.cloudapp.net/

So when I started learning Windows Azure, I of course began with the Windows Azure Training Kit – which has lots of examples and labs, presentations and so on. But from there, I wanted more examples I could learn from, and eventually teach others with. I was asked if I would write a few of those up, so here are the ones I use. CodePlex CodePlex is Microsoft’s version of an “Open Source” repository. Anyone can start a project, add code, documentation and more to it and make it available to the world, free of charge, using various licenses as they wish. Microsoft also uses this location for most of the examples we publish, and sample databases for SQL Server. If you search in CodePlex for “Azure”, you’ll come back with a list of projects that folks have posted, including those of us at Microsoft. The source code and documentation are there, so you can learn using actual examples of code that will do what you need. There’s everything from a simple table query to a full project that is sort of a “Corporate Dropbox” that uses Windows Azure Storage. The advantage is that this code is immediately usable. It’s searchable, and you can often find a complete solution to meet your needs. The disadvantage is that the code is pretty specific – it may not cover a huge project like you’re looking for. Also, depending on the author(s), you might not find the documentation level you want.

If you’re not familiar with this resource, make sure you read up on it. Long before I joined Microsoft I used their work in my daily job – saved a ton of time. It has resources not only for Windows Azure but other Microsoft software as well. The Patterns and Practices group also publishes full books – you can buy these, but many are also online for free. There’s an end-to-end example for Windows Azure using a company called “Tailspin”, and the work covers not only the code but the design of the full solution. If you really want to understand the thought that goes into a Platform-as-a-Service solution, this is an excellent resource. The advantages are that this is a book, it’s complete, and it includes a discussion of design decisions. The disadvantage is that it’s a little over a year old – and in “Cloud” years that’s a lot. So many things have changed, improved, and have been added that you need to treat this as a resource, but not the only one. Still, highly recommended.

And it would be great if you could actually play with the completed application, to see how it really functions on the actual platform. That’s the Azure Stock Trader application. There’s a place where you can read about the application, and then it’s been published to Windows Azure – the production platform – and you can use it, explore, and see how it performs. I use this application all the time to demonstrate Windows Azure, or a particular part of Windows Azure. The advantage is that this is an end-to-end application, and online as well. The disadvantage is that it takes a bit of self-learning to work through.  Links: Learn it: http://msdn.microsoft.com/en-us/netframework/bb499684 Use it: https://azurestocktrader.cloudapp.net/
