• The conventional location for storing my Java libraries and applications in UNIX based systems

  - by Bytecode Ninja

  I usually store the Java applications and JAR files that I download from the Web in the ~/Java folder on my computer (an OS X machine). I have been doing this since the days when I was a Windows user. However I think in UNIX based systems user local apps are conventionally stored in another directory. I have a feeling that this directory should either be /usr/local/, /usr/local/USERNAME, /opt/local, or /opt/local/USERNAME but I am not sure. Any ideas which directory can I use for this purpose? Please note that, I am talking about archive files that I download from the Web, unpack and use locally and not programs that have installation scripts or MacPorts, etc.

• ASP.NET, Visual Studio and Subversion - how to integrate?

  - by Michael Stum

  I use AnkhSVN and Visual Studio 2005 and 2008. Now, one thing that bugs me is that Ankh does not really work with ASP.NET sites. I cannot add them properly to a repository and it won't detect changes, especially because the site is on a remote server accessed through Frontpage Extensions (File = Open Site). What are the alternatives? Does a better plug-in exist? Manually downloading the files through FTP and using TortoiseSVN or svn.exe is not really the level of integration I want :) I want to stay within the Visual Studio IDE when possible. Also, I do not control the remote Server, so I can not install anything on it, which means the whole change tracking/comparison to repository has to be done on my machine.

• XMLHttpRequest cross site scripting on same server but differnt port

  - by clamp

  hello, using XMLHttpRequest it is not possible to open a connection to a document on a different domain than where the page itself is hosted. but what about different ports? for example i have a webserver running on my machine listening on port 80 so the webaddress would look like this: http://localhost:80/mypage.html and i have another webserver running on localhost which is meant to process the ajax requests but listens on a different port. so the javascript in mypage.html would look like this: var xmlhttprequest = new XMLHttpRequest(); xmlhttp.open("GET", "http://localhost:1234/?parameters", true); xmlhttp.send(); would this work? or will it give a security exception as well?

• User.Identity.Name returning NT AUTHORITY\NETWORK SERVICE i want Domain\USER

  - by Jalvemo

  in my asp.net MVC project i have an database connection with connectionstring: Data Source=.;Initial Catalog=dbname;Integrated Security=True All users can execute Stored Procedures on that connection and i want to log those users. so after each execution I store "User.Identity.Name" to another database. This work great on my development machine but after deployment, to access the site i have to go through a VPN-connention and then remote desktop to the same server that the IIS is running on and use a web-browser there. Then i get User.Identity.Name: "NT AUTHORITY\NETWORK SERVICE". i would expect it to be the credentials i entered in remote desktop that have access to the database. any idea how i can get this to work? iis6 authentication: "windows authentication: enabled" web.config:

• Does this have anything to do with endian-ness?

  - by eSKay

  This piece of code: #include<stdio.h> void hello() { printf("hello\n"); } void bye() { printf("bye\n"); } int main() { printf("%p\n", hello); printf("%p\n", bye); return 0; } output on my machine: 0x80483f4 0x8048408 [second address is bigger in value] on Codepad 0x8048541 0x8048511 [second address is smaller in value] Does this have anything to do with endian-ness of the machines? If not, Why the difference in the ordering of the addresses? Also, Why the difference in the difference? 0x8048541 - 0x8048511 = 0x30 0x8048408 - 0x80483f4 = 0x14 Btw, I just checked. This code (taken from here) says that both the machines are Little-Endian #include<stdio.h> int main() { int num = 1; if(*(char *)&num == 1) printf("Little-Endian\n"); else printf("Big-Endian\n"); return 0; }

• Problem when using \LaTeX \includegraphics with some PDF files

  - by brandstaetter

  I noticed some strange effects when including existing pdf graphics in my laTeX documents: Most file work flawlessly, but some PDFs that were created on a different machine (or from the web) cause the whole page on which they are embedded to become ever-so-slightly distorted. I only notice the difference in a side-by-side comparison, but once you see it, it's obvious. The text layout seems slightly broken, and when you zoom in you can see it better. I will try to make some screenshots to further elaborate, but in the meantime: Has anyone seen this before and how can I get rid of these distortions?

• How do I prevent race condition WITHOUT using locks in C++?

  - by Hristo

  How do I prevent a race condition WITHOUT locking or using mutexes/semaphors in C++? I'm dealing with a nested for loop in which I will be setting a value in an array: for (int i = 0; i < m; ++i) for (int j = 0; j < n; ++j) for (int k = 0; k < o; ++k) array[k] += foo(...); More or less, I want to deal with this so that I can ensure different threads running at the same time don't write to array[k] at the same time. Any suggestions on how to approach this? Edit: I am running on a Linux machine and I also have to use the Intel compiler. I will be using "icc" instead of "gcc" to compile the code.

• How to set -Xbootclasspath for a JRE with a custom launcher?

  - by Tom

  I have a Java application which is using a certain Java Runtime Environment. The application uses it's own launcher to startup the java virtual machine. No use of the java.exe, javaw.exe, javaws.exe binaries is being made -- as the application seems to have it's own launcher which is a different executable. This custom launcher is using the rest of the JRE files, such as bin/client/jvm.dll and rt.jar package etc. Now, the problem is that I want to set a boot class path for this custom launcher. The custom launcher does not support the -Xbootclasspath command line parameter, like the default java.exe does. Is there any way for me to set the boot class path now for this java runtime environment? Thanks in advance. Some things to keep in mind: I do not have the source of this application This is meant for self and personal debugging use only, not for distribution

• Calling C/C++ library function from PHP

  - by Anon. BlackBerry Developer

  We have a PHP web app running on a customer's machine. For an update, we have a bit of code in C that we'd like to include as a native opaque library along with the PHP web app. How does one go about calling a C/C++ lib. function from PHP? It cannot be assumed that the PHP app, called by the web server, has any sort of permission to call an exec(), eval(), or system() type of function to execute a C wrapper driver which in turn uses the C/C++ library, so it would need to be a direct C library use from within the PHP code.

• Runtime Error in asp.net site?

  - by Surya sasidhar

  hi, I developed a website in asp.net and i place the site in online. I upload my site in online by using CuteFTP. After uploading when i type my url it is giving error like this... Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.

• Detect if an assembly is available

  - by jgaa

  I'm implementing an installer in Java, that is supposed to download and install an application for non-privileged users in Windows (from XP and up). The application is written in C++, and depend on the usual VC runtime-libraries (msvcm90.dll and friends). In order to save bandwidth, I want to avoid downloading the VC redistributables if they already are available for the user. I do however have a problem finding a reliable method to detect if an assembly is installed. If the assembly is missing, I will deploy it as described here: http://msdn.microsoft.com/en-us/library/ms235291%28VS.80%29.aspx So the question is simply how to detect if a (any) assembly is installed on the machine. It's no requirement that this can be done from Java. I can easily write a small probe in C++ and link it statically for the task. jgaa

• Using Google Map Headers (YM4R) on Heroku

  - by Kevin

  I have the following at the top of my view: <%= GMap.header %> Heroku is giving me an ActionView::TemplateError on that line.... this works on my own machine but not on Heroku.... why is that? Is there something about Heroku that doesn't allow? In the final compile on the browser, the above code translates into this on the client side: <script src="http://maps.google.com/maps?file=api&amp;v=2.x&amp;key=XXXXX;hl=&amp;sensor=false" type="text/javascript"> </script> <script src="/javascripts/ym4r-gm.js" type="text/javascript"></script>

• Asp.net profile in a separate assembly

  - by Shimrod

  Hi everyone, I have a web application which uses membership and profiles. I successfully used the WebProfileBuilder extension, so my profile class is correctly generated, and is working nicely. However, after a new request of my client, I need now to move that profile management part into another assembly (so I'd be able to get profile information in a windows service running on the same machine). What I made is created the new assembly, moved my generated profile file, and tried to use it from the other assembly, but without any success. I always get a SettingsPropertyNotFoundException. My tought is that the profile system doesn't know where to find its connection information, so I tried to add the connectionstring and provider in the app.config of this assembly, but this doesn't seem to work. What am I missing ? Is it possible to do ? Thanks in advance!

• How to refresh database data only in SQL Server

  - by MaxGeek

  So I want to copy just the data from a Prod database (SQL 2005) down to my local machine (SQL 2005 & SQL 2008 Management Studio installed). The problem is I'm running into foreign key constraints that are causing the task/scripts to fail. I can get by these errors if I import certain tables first, but is there an easier way to do this all at once? I'm not a DBA so I don't have access to the database back up. I've tried the SQL Import/Export data Wizard and Publishing Wizard, but it also gets the PK error.

• m and s keys do not work over vnc connection to ubuntu server

  - by Don

  I'm new at setting a lot of this up, so bear with me. I installed Ubuntu 10.4 server on a 64 bit machine. Then I added vnc so I could manage it while it's racked. I start the server, SSH to it, and run vncserver :1 At this point, all keys work fine. Next I exit out of the SSH session and fire up my client vnc app. I connect via the IP :1, enter my password, and everything seems to be fine. Now when I enter a terminal (through the vnc connection) I cannot type lowercase "s" or "m" (upper case works). I've tried on two different pc's running the vnc client, but it's the same. I also installed the latest updates from Ubuntu as of today. Thanks for any help.

  I want to use Originate API of Asterisk to place an outbound call on a FXO channel, for testing purpose I am using X100P card and, as expected, card is not able to detect if the number is busy/ringing or when it is answered. I want to know which card should I use so that I can get such basic events ... I am not really interested in detailed call progress analysis for answering machine or live voice. I just need basic busy/ringing and answer events and maybe a dis-connect event. Thanks.

• How to authenticate users against a Windows AD?

  - by Potinos

  I've a JSF-Hibernate web application. I need to authenticate users against a Windows AD and the web application should only allow logins from members of group X, otherwise it should redirect to an error page. How can I configure this? Also, I would like to display the name of the logged-in user on all pages, not the name of the Windows user of the server machine. I have tried the System.property("user.name") for this, but this only returns the name of the Windows user of the server name.

• Error in vb.net windows service when connecting to SQL

  - by Clint

  I've installed a vb.net windows service on a Windows 2008 machine, that is attempting to connect to SQL 2005. The service starts succesfully, but can't see the database. The event log has the following entry. The description for Event ID 0 from source SU4.ESMR.DAL.Job.FillPriorityJobByType(oJobDS, TypeID: 3 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. This was tested locally on both XP and 2008. All environments are 32 bit.

• What is the easiest way to deploy a MVC2 application from Visual Studio 2010 to IIS 7.5?

  - by Richard

  I´ve tried a couple of different ways to deploy a application to a IIS 7.5 running on my machine for testing purposes and i´ve sort of hit a wall. Nothing works out of the box. Everything assumes I have knowledge I don't have and would prefer not to have to aqquire. Google isn't really helping either with answers ranging from "copy files by hand" to "install teamcity and set it up for CI". I have set up TeamCity for java projects before and it's really over kill for my needs at the moment. So anyone know of a fast, simple and easy way to deploy a application during testing/building?

• How SEO friendly is this URL ?

  - by The_AlienCoder

  I have this products catalog site.For the sake of SEO, I would have wanted my 'view details' link to look some thing like this ~/products/26-productname or ~/products/26/productname On my machine I'm using a url re-writing module and it works well. Unfortunately My host(shared) does not support url re-writing modules or Aspnet 4.0 for now. So I came up with a workaround that attempts to be SEO friendly Instead of this : ~/Products/details.aspx?id=26 I decided to simply append the product name in the url and i.e ~/Products/details.aspx?product=26-Toshiba Qosmio Notebook So my question is how SEO friendly is such a URL and is my attempt worth anything at all?

• Can Visual Studio exclude certain folders when searching for header files?

  - by identitycrisisuk

  I'm having trouble with a library that we are using, which has two copies of header files that are needed - one which we are modifying and building from and another which is automatically created during the build process. I don't fully know why or really want to change this but it can cause a bit of annoyance when on random occasions the go to definition function takes you to the auto created header instead of the one used to build. Usually you can spot it but sometimes you don't and make changes to the auto created one, which are then overwritten or sometimes stay around for a while so that something works on your machine but breaks on other peoples. I don't know if there is any way around this as the auto created folder is in the additional include directories of some of the projects in the solution but I just thought I would ask if there was any good way of reducing the chance of this annoying situation cropping up.

• How can I know if a computer supports hardware-assisted virtualization before I purchase the computer?

  - by Poaters

  I'm an iPhone programmer who is no longer in possession of a personal Mac computer on which to use XCode. I have two Windows desktops, and I would like to run OS X in VMWare rather than purchase Apple's expensive hardware. However, neither of my machines supports hardware-assisted virtualization, which is required to virtualize OS X. I went shopping online for a computer today, since I've been planning to purchase a laptop anyway, but sites like Best Buy don't appear to give any indication of whether or not a product supports this. Is there any other site out there or some trick to figuring this out other than buying the machine and running Microsoft's nifty little detection tool?
