• Proper way to handle issue when porting 32 to 64 bit. Conversion from DT1 to DT2 of greater size

  - by grobartn

  So I am trying to port 32 bit to 64 bit. I have turned on the VS2008 flag for detecting problems with 64 bit. I am trying following: char * pList = (char *)uiTmp); warning C4312: 'type cast' : conversion from 'unsigned int' to 'char *' of greater size Disregard the code itself. This is also true for any pointer, because 64 bit pointer is greater than 32 bit unsigned int or int for that purpose. Given that you have to cast smaller type to greater how would you go about doing it so it correctly on both 32/64 bit systems

• Loading jQuery with Tapestry 5

  - by American Yak

  Okay, so I'm not a Java guy, but I work with loads of them. We generally load Prototype with Tapestry 5, as Tapestry was built on this javascript library. As a UI/front end developer/engineer, I know the awesomeness of jQuery and the lack of prototype therein. (Feel free to debate that elsewhere -- this ticket doesn't concern that question, ha.) I've been curious for some time if it's possible to port jQuery into Tapestry instead of Prototype -- as in completely removing Prototype and Scriptaculous -- I realize it kind of defeats the purpose of the already bundled Prototype, but I wanted other opinions on the matter. Thanks.

• Leaving SQL Management open on the internet

  - by Tim Fraud

  I am a developer, but every so often need access to our production database -- yeah, poor practice, but anyway... My boss doesn't want me directly on the box using RDP, and so we decided to just permit MS SQL Management Console access so that I can do my tasks. So right now we have the SQL box somewhat accessible on the internet (on port 1433 if I am not mistaken), which opens a security hole. But I am wondering, how much of an uncommon practice is this, and what defaults should I be concerned about? We use MSSQL2008 and I created an account that has Read-Only access, because my production tasks only need that. I didn't see any unusual default accounts with default passwords on the system, so I would be interested to hear your take. (And of-course, is there a better way?)

• ORB forwards to a wrong location

  - by dave-keiture

  I have an orbd started at a virtual host (with the IP A), with some remote object registered. Box that hosts virual boxes has IP B. When client tries to connect to the ORB at A to acquire the NamingContext, ORB replies with a LocationForward message poiniting to host B and port 1049 (like if another ORB would be started at that host). NamingContext is returned successfully, but obviously I'm not able to acqure the objects, registered at the NamingContext (at ORB hosted at A) by the name. Could anyone please explain what's happening? How can I access the orb hosted at A remotely? Thanks in advance.

• Determine phone number based on time zone?

  - by Zachary Burt

  I have a (potentially international) phone number. It may or may not have a country code prefix. Does anyone know of a database that will help me map phone number = time zone? I would even just like to map phone number = country, since I can probably create country = time zone by scraping existing data on the web. This is a more complicated problem than it looks; for example, how do I know if it's a US-based number -- e.g. is it a USA area code, or an international country calling code? Any language is fine; I can port it.

• How to use #ifdef entities as part of functions in header files

  - by Crazyjavahacking

  I would like to ask if it is possible to use the entities defined in #ifdef block in header files. To be clear, I have following code: #ifdef #include <winsock2.h> #define SOCKET_HANDLE SOCKET #define CONNECTION_HANDLE SOCKET #endif SOCKET_HANDLE createServerSocket(const char* hostAddress, short port); I am Java developer and this seems completely fine for me. However compiler has a problem with this. Can you explain why is that code a problem? Also how can I force to compile it. (The idea is to have generic interface and conditional compilation to determine real types according to running platform at compile time.) Thanks

• How to determine IP used by client connecting to INADDR_ANY listener socket in C

  - by codebox_rob

  I have a network server application written in C, the listener is bound using INADDR_ANY so it can accept connections via any of the IP addresses of the host on which it is installed. I need to determine which of the server's IP addresses the client used when establishing its connection - actually I just need to know whether they connected via the loopback address 127.0.0.1 or not. Partial code sample as follows (I can post the whole thing if it helps): static struct sockaddr_in serverAddress; serverAddress.sin_family = AF_INET; serverAddress.sin_addr.s_addr = INADDR_ANY; serverAddress.sin_port = htons(port); bind(listener, (struct sockaddr *) &serverAddress, sizeof(serverAddress)); listen(listener, CONNECTION_BACKLOG); SOCKET socketfd; static struct sockaddr_in clientAddress; ... socketfd = accept(listener, (struct sockaddr *) &clientAddress, &length);

• What c# equivalent encoding does Python's hash.digest() use ?

  - by The_AlienCoder

  I am trying to port a python program to c#. Here is the line that's supposed to be a walkthrough but is currently tormenting me: hash = hashlib.md5(inputstring).digest() After generating a similar MD5 hash in c# It is absolutely vital that I create a similar hash string as the original python program or my whole application will fail. My confusion lies in which encoding to use when converting to string in c# i.e ?Encoding enc = new ?Encoding(); string Hash =enc.GetString(HashBytes); //HashBytes is my generated hash Because I am unable to create two similar hashes when using Encoding.Default i.e string Hash = Encoding.Default.GetString(HashBytes); So I'm thinking knowing the deafult hash.digest() encoding for python would help

• .NET Runtime Object Browser.

  - by user290907

  Is there a framework which can be used in your application, to make it expose internal objects on some port for inspection. for.e.g. after i start my application in this case a GUI Application, and then say launch http://localhost:9100 then it should show me the statistics of the app. I played a bit with HttpListener accepting connections and then outputting raw HTML, it works fine for simple tasks, but there is too much worked involved if i have make a proper object browser. Thanks in Advance.

• What is the Sql Server equivalent for Oracle's DBMS_ASSERT?

  - by dotNetYum

  DBMS_ASSERT is one of the keys to prevent SQL injection attacks in Oracle. I tried a cursory search...is there any SQL Server 2005/2008 equivalent for this functionality? I am looking for a specific implementation that has a counterpart of all the respective Oracle package members of DBMS_ASSERT. NOOP SIMPLE_SQL_NAME QUALIFIED_SQL_NAME SCHEMA_NAME I know the best-practices of preventing injection...bind variables...being one of them. But,in this question I am specifically looking for a good way to sanitize input...in scenarios where bind-variables were not used. Do you have any specific implemetations? Is there a library that actually is a SQL Server Port of the Oracle package?

• WCF: What happens if a channel is established but no method is called?

  - by mafutrct

  In my specific case: A WCF connection is established, but the only method with "IsInitiating=true" (the login method) is never called. What happens? In case the connection is closed due to inactivity after some time: Which setting configures this timeout? Is there still a way for a client to keep the connection alive? Reason for this question: I'm considering the above case as a possible security hole. Imagine many clients connecting to a server without logging in thus preventing other clients from connecting due to bandwidth problems or port shortage or lack of processing power or ... Am I dreaming, or is this an actual issue?

• Rewriting ASP.NET (.aspx) pages in Apache

  - by whitstone86

  I managed to get ASP.NET to work in Apache, as per http://weblogs.asp.net/israelio/archive/2005/09/11/424852.aspx but I'm unsure how to get it to rewrite pages, with a web.config file. I've tried using Google endlessly, but came to nothing. What's the best solution for me to rename my pages, e.g. mytestpage.aspx to mytestpage.htm Also, anyone know how to get IIS and MySQL working? I've tried but I'm struggling to get it to work. I did this simply because I needed multiple sites on port 80 on localhost, and the website I'm developing is not suited to PHP. IIS is installed, but not being used at the moment. Thanks

• Sending a large file over network continuously

  - by David Parunakian

  Hello, We need to write software that would continuously (i.e. new data is sent as it becomes available) send very large files (several Tb) to several destinations simultaneously. Some destinations have a dedicated fiber connection to the source, while some do not. Several questions arise: We plan to use TCP sockets for this task. What failover procedure would you recommend in order to handle network outages and dropped connections? What should happen upon upload completion: should the server close the socket? If so, then is it a good design decision to have another daemon provide file checksums on another port? Could you recommend a method to handle corrupted files, aside from downloading them again? Perhaps I could break them into 10Mb chunks and calculate checksums for each chunk separately? Thanks.

• acts_as_ferret with multiple hosts

  - by Nick

  I've got everything working with ferret and acts_as_ferret for development (or localhost DRb), but I can't get my multiple host deployment working. All of the remote systems get ECONNREFUSED when accessing the port. On the ferret server, the daemon is listening on localhost only despite the configuration listing the FQDN as the host. I also tried switching to a UNIX socket to share data between the ferret DRb daemon and the app code but it too gets ECONNREFUSED. (The socket is available to all of the machines via an NFS mount). Is there a better way to do this or should I be looking for another search indexer? Thanks.

• How can I load an MP3 or similar music file for display and anaysis in wxWdigets?

  - by Jon Cage

  I'm developing a GUI in wxPython which allows a user to generate sequences of colours for some toys I'm building. Part of the program needs to load an MP3 (and potentially other formats further down the line) and display it to the user. That shuold be sufficient to get started but later I'd like to add features like identifying beats and some crude frequency analysis. Is there any simple way of loading / understanding an MP3's contents to display a plot of it's amplitudes to the screen using wxWidgets? I later intend to port to C++/wxWidgets for speed and to avoid having to distribute wxPython.

• Killing a subprocess including its children from python

  - by user316664

  Hi, I'm using the subprocess module on python 2.5 to spawn a java program (the selenium server, to be precise) as follows: import os import subprocess display = 0 log_file_path = "/tmp/selenium_log.txt" selenium_port = 4455 selenium_folder_path = "/wherever/selenium/lies" env = os.environ env["DISPLAY"] = ":%d.0" % display command = ["java", "-server", "-jar", 'selenium-server.jar', "-port %d" % selenium_port] log = open(log_file_path, 'a') comm = ' '.join(command) selenium_server_process = subprocess.Popen(comm, cwd=selenium_folder_path, stdout=log, stderr=log, env=env, shell=True) This process is supposed to get killed once the automated tests are finished. I'm using os.kill to do this: os.killpg(selenium_server_process.pid, signal.SIGTERM) selenium_server_process.wait() This does not work. The reason is that the shell subprocess spawns another processfor the java program, and the pid of that process is unknown to my python code. I've tried killing the process group with os.killpg, but that kills also the python process which runs this code in the first place. Setting shell to false, thus avoiding the java program to run inside a shell environment, is also out of the question, due to other reasons. Does anyone have an idea how I can kill the shell and any other processes generated by it? Cheers, Ulas

• Setting up scripts in Amazon EC2 Cloud

  - by racket99

  Hello, I am currently running a few perl and python scripts on a windows pc and would like to port over to the Amazon EC2 servers running 64-bit LINUX. The scripts are basic web scrapers that go to a variety of websites, get data and then save daily as csv files. I would like to install these in the cloud and get them running in an automated way so that they will run without my intervention. Also given that I don't want to lose all the data if the instance crashes, I should also upload the csv files to Amazon S3. Any idea how I can do this? I am not terribly versed in LINUX nor do I know Perl/Python well. What is the best way for me to tackle thi

• Simple performance testing tool in C#?

  - by Tomas

  Hi, At first -I need to do it as my university project so I am not interested in using existing tools. I would like to know whether it is even possible to write a very simple tool that I could use for performance testing of web applications. It would only record actions (I do not know, maybe just packet sniffering?) and then replay. However I have basic idea (record packets on port 80 and sending them again), I do not know how to measure time for each transaction as they are not differentiated. Any help is greatly appreciated, thank you!
