• mpicc hangs when called from makefile; runs fine as single command

  - by user2518579

  i'm trying to compile WRF (doubt that's relevant) and am having a problem where mpicc will hang when run w/ the compile script. icc and mpif90 have no issues. the compile script is executed w/ #!/bin/csh -f just to be verbose, here's an example. i run the script and get here make[3]: Entering directory `/home/jason/wrf/wrf3.5/external/RSL_LITE' mpicc -DMPI2_SUPPORT -DMPI2_THREAD_SUPPORT -DFSEEKO64_OK -w -O3 -DDM_PARALLEL -DMAX_HISTORY=25 -DNMM_CORE=0 -c rsl_bcast.c and hang. so then i run that line by itself jason@server:~/wrf/wrf3.5$ cd /home/jason/wrf/wrf3.5/external/RSL_LITE jason@server:wrf3.5/external/RSL_LITE$ mpicc -DMPI2_SUPPORT -DMPI2_THREAD_SUPPORT -DFSEEKO64_OK -w -O3 -DDM_PARALLEL -DMAX_HISTORY=25 -DNMM_CORE=0 -c rsl_bcast.c jason@server:wrf3.5/external/RSL_LITE$ compiles instantly. starting the compile script again does the exact same thing but on the next file. i have no idea what to do, and this is basically impossible to google for.

• Does setting an onload event for a <script> tag work consistently in modern browsers?

  - by Matchu

  I observe that placing the following in an external script file has the desired effect in my copies of Firefox and Google Chrome: var s = document.createElement('script'); s.setAttribute('type', 'text/javascript'); s.setAttribute('src', 'http://www.example.com/external_script.js'); s.onload = function () { doSomethingNowThatExternalScriptHasLoaded } document.getElementsByTagName('body')[0].appendChild(s); It adds a an external script tag to them DOM, and attaches a function to the tag for when the script has loaded. I'm having trouble testing in Internet Explorer right now, but I'm not sure if it's related to that addition in particular, or something else. Does this method work in the more modern versions of other browsers, including IE7/8? If not, how else could I go about this?

• Urllib's urlopen breaking on some sites (e.g. StackApps api): returns garbage results

  - by Edan Maor

  I'm using urllib2's urlopen function to try and get a JSON result from the StackOverflow api. The code I'm using: >>> import urllib2 >>> conn = urllib2.urlopen("http://api.stackoverflow.com/0.8/users/") >>> conn.readline() The result I'm getting: '\x1f\x8b\x08\x00\x00\x00\x00\x00\x04\x00\xed\xbd\x07`\x1cI\x96%&/m\xca{\x7fJ\... I'm fairly new to urllib, but this doesn't seem like the result I should be getting. I've tried it in other places and I get what I expect (the same as visiting the address with a browser gives me: a JSON object). Using urlopen on other sites (e.g. "http://google.com") works fine, and gives me actual html. I've also tried using urllib and it gives the same result. I'm pretty stuck, not even knowing where to look to solve this problem. Any ideas?

• file_get_contents() returns "failed to open stream" when used with Facebook access_token flow

  - by TMC

  file_get_contents() is returning "failed to open stream" when I call it on a Facebook oAuth access_token URL. Warning: file_get_contents(https://graph.facebook.com/oauth/access_token?client_id=XXXXX&redirect_uri=http://mydomain.com/fb/callback3.php&client_secret=xxxx&code=YYYY) [function.file-get-contents]: failed to open stream: No error in E:\\htdocs\fb\callback3.php on line 5 (I have removed ClientID, clientSecret and the oAuth Code). If I try to manually hit the Facebook access_token URL that my code is attempting to fetch, I get an actual payload returned in the browser: access_token=XYZ&expires=6508 (where XYZ is the access token) So for some reason, there is a problem with the access_token URL specifically when used with file_get_contents(). At first, I thought it was a security issue with my webhoster, but I have verified with phpinfo() that allow url open is indeed allowed. I have also tried this code and verified it works: $foo = file_get_contents('http://google.com'); echo $foo Anyone have any ideas why file_get_contents() is failing with the Facebook access_token URL?

• Sitemaps on multiple front end servers using a http handler, is that a good idea?

  - by Rihan Meij

  Question 1 We would like to generate a site map for our CMS site We have multiple front end servers with approx a million articles. Environment multiple MS SQL servers multiple front end servers (load balanced) ASP.net - and IIS 6 Windows 2003 To have the site maps (the site map index file, and the site map files) physically on the front end servers will be a operations nightmare and error prone. So we are considering using http handlers instead so that it does not matter what server gets the request, it will be able to serve the correct xml file. Question 2 If we ping Google each time we publish a new article will that effect us negatively if that happens more than once a hour. Thanks!

• Windows Network Programming

  I am planning to get some good book for Windows Socket Programming in VC++. I have 2+ years of experience in working with VC++/ATL/COM/MFC; but not in the networking domain.

Please recommend some good book with Pros and Cons. The books I found are below. Windows Sockets Network programming Network Programming for Microsoft Windows Thanks.

• Using ptrace to generate a stack dump

  - by Gomez

  Hello. I am compiling C++ on *nix and I would like to generate a stack dump a) at an arbitrary point in the program, b) during any signal, particularly during SIGSEGV. Google tells me that ptrace is probably the tool for the job, but I can't find any comprehensible examples of walking the stack. Getting the return address, yeah, but what about the NEXT return address? And what about extracting the symbolic name of the function at that point? Something to do with DWARF? Many thanks if you can tell me where to go from here.

• Rails 3: What is the proper way to respond to REST-ful actions with JSON in rails?

  - by Damien Wilson

  Hello SO. I'm trying to make an API for my rails application using JSON responses to RESTful resource controllers. This is a new experience for me, so I'm looking for some guidance and pointers. To start things off: In a rails application, what is the "proper" way to respond with JSON to REST-ful controller methods? (create, update, destroy) Is there an idiomatic way to indicate success/failure through a JSON response? Additional information: I'm currently working with rails 3.0.beta2 I would like to avoid using a plugin or gem to do the grunt work, my goal is to gain a better understanding of how to make a rails 3 API. Links to places I could find more information on the topic would also be appreciated, some quick searching on google didn't do me much good.

• PECL install fails

  - by James

  Hey! I have browsed every Google result, read all the forum posts about this error, but I cannot solve it. When using PECL install for anything, I always end up getting this error: checking whether the C compiler works... configure: error: cannot run C compiled programs. Everything else succeeds up to that point them bam! I'm using CentOS 4.3, PEAR is the latest stable version, GCC is a stable and recent version. Everything is working as it should, but the C compiler always seems to error. I've tried to make tmp have the right privilages for the operation by temporarily enabling it using: mount -o remount,exec,suid /tmp But that doesn't work. I've literally tried everything that has been suggested by to no avail. Any ideas?

• Visual Studio Team System 2008 - messy formatting/control characters/marks in source code

  - by AL

  Hi, I don't know what I did but somehow the IDE has started displaying a green dot whenever I press spacebar and a green arrowhead whenever I press TAB. The source has become littered with these characters all over and I am finding it very difficult to code in the presence of so many formatting marks. I have tried to search a solution on Google but couldn't perhaps enter the right keywords so haven't been able to fix the behavior. Is there any way I can stop VS2008 IDE from littering my source code with these green dots and arrowheads whenever I press spacebar/tab? I would be really thankful for this help. Thanks, -AL

• GWT Acegi alternative

  - by DroidIn.net

  I'm starting new project. The client interface is based on GWT (and GXT) I have no say it's predetermined. However I can pick and choose as far as server side so I can have some fun and hopefully learn something new in the process. Some requirements are : Exchange with server will be through use of JSON, most if not all of UI will be generated by GWT (JS) on the client, so the client/serve exchange will be limited to data exchange as much as possible No Hibernate (it's not really supported on the proprietary db I will be connecting to). In the past projects people would use JDBC or iBATIS Some sort of IoC (I'm thinking Guice just to stick with Google) Some sort of Security framework based on LDAP. In the past we would use Spring security (Acegi) but it wasn't ideal and we had to customize it a lot So basically should I stick with tried-and-true Spring/Acegi or try something based on Guice? And what that "something" would be and how mature is it?

• How does Windows LIve ID work?

  - by Morgan Cheng

  I happens to find this nice article explaining how OpenID works. Clearly, OpenID consumer and OpenID server transfer information through URL query string. I'm wondering how Live ID accomplish similar functionality. It seems the info is not exchanged through query string in URL. And, since Live ID login server have different domain name from consumer domain, it is not applicable to transfer info through cookie. I tried to google tutorial of Live ID, but the result is full of jargon and hard to understand. Is there any easy-to-understand tutorial about How Live ID works?

• Parse HTML file to grab all ID and Classes for a CSS file

  - by iamfriendly

  Hey all, A short while ago, I'm fairly certain I came across an application (or perhaps a plugin for Coda - the IDE I use) which quickly parses a html document and then spits out all of the elements with IDs and Classes for me to use in a CSS file. Having fully 'got into' zen coding - using the wonderful TEA plugin for Coda, I'm now hot on the heels of this app/plugin again. I've tried and failed miserably at hunting through Google, but have come up completely empty handed. Does anyone know of anything which can do this? Happy New Year everyone!

• C# UTF8 output keep encoded characters intact

  - by Stefan Pohl

  Hello, i have a very simple question I can't seem to get my head around. I have a properly encoded UTF8-String I parse into a JObject with Json.NET, fiddle around with some values and write it to the commandline, keeping the encoded characters intact. Everything works great except for the keeping the encoded characters intact part. Code: var json = "{roster: [[\"Tulg\u00f4r\", 990, 1055]]}"; var j = JObject.Parse(json); for (int i = 0; i < j["roster"].Count(); i++) { j["roster"][i][1] = ((int)j["roster"][i][1]) * 3; j["roster"][i][2] = ((int)j["roster"][i][2]) * 3; } Console.WriteLine(JsonConvert.SerializeObject(j, Formatting.None)); Actual Output: {"roster":[["Tulgôr",2970,3165]]} Desired Output: {"roster":[["Tulg\u00f4r",2970,3165]]} It seems like my phrasing in Google is inappropriate since nothing useful came up. I'm sure it's something uber-easy and i will feel pretty stupid afterwards. :)

  - by b0x0rz

  is there a project hosting for c# code and that has a simple to use visual studio plugin? does not need to be free. it does need to be private. should have a plugin or already by usable from within visual studio. something like a hosted team foundation server would be best, however i only found one and for $150 per user per month. a bit much, don't you think :P the problem with searching via google is that there is a lot of free project hostings for open source and can't seem to weed them out :( thnx a lot for any info

• Is there a calculator with LaTeX-syntax?

  - by Jørgen Fogh

  When I write math in LaTeX I often need to perform simple arithmetic on numbers in my LaTeX source, like 515.1544 + 454 = ???. I usually copy-paste the LaTeX code into Google to get the result, but I still have to manually change the syntax, e.g. \frac{154,7}{25} - (289 - \frac{1337}{42}) must be changed to 154,7/25 - (289 - 1337/42) It seems trivial to write a program to do this for the most commonly used operations. Is there a calculator which understand this syntax? EDIT: I know that doing this perfectly is impossible (because of the halting problem). Doing it for the simple cases I need is trivial. \frac, \cdot, \sqrt and a few other tags would do the trick. The program could just return an error for cases it does not understand.

• How load text into JavaStackTraceConsolePage programmatically?

  - by Marcel

  In my Eclipse plugin I'd like to send a Java console output (loaded from some other system) to the Java Stack Trace Console. I pseudo-code it'd be something like: get the console output from the other system obtain a reference to a JavaStackTraceConsolePage instance send the text to the console page display the console i.e. switch from my plugin's view to the Console view Step 1 is easy as it is specific to my plugin. As for the rest I'm pretty much clueless - Google and stackoverflow.com don't come up with useful references or how-tos. Since the class JavaStackTraceConsolePage is part of an internal Eclipse API (org.eclipse.jdt.internal.debug.ui.console) I'm not even sure whether it's doable at all.

• In what programing language are the things i actualy care about writin? [closed]

  To be more specific and less subjective: In what language are video games like Halo 3/COD 4/ mario cart written? Microsoft word for windows? for mac? The animation software used by big movie studios to make movies like toystory and monsters inc? The software that helps pilots control the F22 raptor? The software that watches the stock market? The software in the computer in my car? The software that makes the internet work? (this one is a bit vague, if more specificness is needed then google specifically) robots?

• AppleScript to open URL in Safari crashes for Flash-based websites

  - by Mark

  I'm trying to open a URL in Safari. It works fine for websites without Flash embedded, but crashes Safari for Flash sites. Example (this WORKS): tell application "Safari" to open location "http://google.com" This CRASHES when Safari is not already running: tell application "Safari" to open location "http://grooveshark.com" Two things I noticed: Safari only crashes for websites with embedded Flash The script above only crashes if a new instance of Safari is created (i.e. Safari was not running before) From the second observation I assume that it could be a permission issue of some sort. Maybe the Safari instance launched from the AppleScript has a problem loading plugins?

• Parse error when trying to install app on Asus eee PC 701 running Android 2.0

  - by Don

  A beta tester of mine has a Asus eee pc 701 running Android 2.0 and he is trying to install an app on it from my web site. He is able to download the app but is getting a "Parse Error: There is a problem parsing the package" error. I don't really know if this problem is with the eee pc or with the apk since he is the first person to try to install it. I built it for 2.0, the manifest has 5 as the minimum API level and I used Eclipse to export and sign it. But this is my first Android app and he is the first to try to install it, so I am not sure what the problem might be? Could just be the Android implementation too. Here is a site about putting Android on the Asus: http://www.liliputing.com/2009/01/how-to-built-google-android-for-the-asus-eee-pc-701.html Any thoughts on what I might try to get this app installed on his machine?

• Reading Local Group Policy / Active Directory Settings

  - by Shinobi

  I'm writing a C# program that will enforce password complexity in accordance with the Windows Group Policy setting "Password must meet complexity requirements". Specifically, if that policy is set to Enabled either on the local machine (if it's not part of a domain) or by the Domain Security Policy (for domain members), then my software needs to enforce a complex password for its own internal security. The issue is that I can't figure out how to read that GPO setting. Google searches have indicated that I can read GPO settings with one of these two APIs: the System.DirectoryServices library in .NET Framework, and Windows Management Instrumentation (WMI), but I haven't had any success so far. Any insights would be helpful.
