• Displaying build times in Visual Studio?

  - by Roger Lipscombe

  Our build server is taking too long to build one of our C++ projects. It uses Visual Studio 2008. Is there any way to get devenv.com to log the time taken to build each project in the solution, so that I know where to focus my efforts? Improved hardware is not an option in this case. I've tried setting the output verbosity (under Tools / Options / Projects and Solutions / Build and Run / MSBuild project build output verbosity). This doesn't seem to have any effect in the IDE. When running MSBuild from the command line (and, for Visual Studio 2008, it needs to be MSBuild v3.5), it displays the total time elapsed at the end, but not in the IDE. I really wanted a time-taken report for each project in the solution, so that I could figure out where the build process was taking its time. Alternatively, since we actually use NAnt to drive the build process (we use Jetbrains TeamCity), is there a way to get NAnt to tell me the time taken for each step?

• What is the scope of JS variables in anonymous functions

  - by smorhaim

  Why does this code returns $products empty? If I test for $products inside the function it does show data... but once it finishes I can't seem to get the data. var $products = new Array(); connection.query($sql, function(err, rows, fields) { if (err) throw err; for(i=0; i< rows.length; i++) { $products[rows[i].source_identifier] = "xyz"; } }); connection.end(); console.log($products); // Shows empty.

• How to force programs out of swap file when a resources-intensive batch finishes?

  - by sharptooth

  We use employees' desktops for CPU-intensive simulation during the night. Desktops run Windows - usually Windows XP. Employees don't log off, they just lock the desktops, switch off their monitors and go. Every employee has a configuration file which he can edit to specify when he is most likely out of office. When that time comes a background program grabs data for simulation from the server, spawns worker processes, watches them, gets results and sends them to the server. When the time specified by the employee elapses simulation stops so that normal desktop usage is not interfered. The problem is that simuation consumes a lot of memory, so when the worker processes run they force other programs into the swap file. So when the employee comes all the programs he left are luggish and slow until he opens them one by one so that they are unswapped. Is there a way the program can force other programs out of swap file when it stops simulation so that they again run smoothly?

• Websphere exception handling

  - by Benjamin

  Hi all, From a security standpoint, what is the best solution to handle application errors with Websphere? I've been thinking of creating a class that is called every time an application error is generated, log the error and display a generic error message to the users. In PHP this can be achieved using the set_exception_handler() function. Is there something similar for websphere that could be configured in the web.xml? I've found codes like this on the internet: <error-page> <error-code>500</error-code> <location>/servlet/ExceptionHandlerServlet</location> </error-page> But that would only work with "500" HTTP error codes. I really want something generic that catches everything. Something like a class that implements a certain interface which can have access to all information about the error. Thanks for your time.

• importing CELERY* environment variables in django settings.py causes celeryd not to start

  - by Taras

  I just spent 2 hours trying to figure out why django celery stopped working. Celery would being to start, but would stop short of printing out the configuration items, implying that it wasn't starting correct. The log would only contain The celery.decorators module along with the magic keyword arguments, are deprecated, and will be removed in version 3.0. Please use the celery.task module instead of celery.decorators, and the task.request should be used instead of the magic keyword arguments: from celery.task import task See http://bit.ly/celery22major for more information. """)) It turns out that some celery env variables that I was importing to try and fix a different problem were causing celery not to start correctly: from celery.tests.config import CELERY_QUEUES, CELERY_DEFAULT_QUEUE, CELERY_DEFAULT_ROUTING_KEY Even though I wasn't using them anywhere. Does anyone know what was happening?

• How to get hudson to display the SCM diff since last build in the individual build page

  - by Steen

  I'm not sure it's even possible, but my command line usecase goes something like this: do svn update do a svn log -l {how many times since my last commit - 1} do a `svn diff -rHEAD:{my last commit revision + 1} and try to get an overview of what happened since last time I touched the code. I get a lot of valuable information from this, and would like everybody in my team to get the same feeling of control and overview of the code base. Not everyone in my team is comfortable with the command line but like the hudson interface. So; is there a way to the the commit diff since last build (we do a build per commit) in the individual build page?

• visual studio 2002: c# threading question

  - by dotnet-practitioner

  Hi, I have a piece of code where I send a file content over tcp/ip channel. There are times when this connection hangs causing entire application to freeze. Is there a way for my main thread to spawn a worker thread and monitor that worker thread. If worker thread succeeds, well and good. If it hangs , the main thread could log error message and continue. How can I simulate in my test code that a worker thread is hanging. please let me know what could the code look like. I am using C# Visual studio 2002.

• Is it possible to use Integrated Windows Auth when Server isn't on the domain?

  - by jskentzos

  Our production web servers ARE NOT part of the domain, but we'd like people to be able to log in automatically since they are logged into the domain on their PC. Is there anyway to get the browser (IE7+) to send the appropriate information to the server (IIS6) so I can retrieve the ServerVariables["AUTH_USER"] or ServerVariables["LOGON_USER"]? I presume the answer is no since if I set the security for windows auth to "on" and anonymous access to "off", then the server wouldn't know what do do with any user information for a domain which it has no knowledge of. I just want to know for sure before I give the SSO team a "not possible" answer.

• MySQL slow queries

  - by jack

  The MySQL slow query log often shows a bunch of following entries in sequence. SET timestamp=1268999330; commit; # User@Host: username[username] @ localhost [] # Query_time: 4.172700 Lock_time: 0.000000 Rows_sent: 0 Rows_examined: 0 SET timestamp=1268999330; commit; # User@Host: username[username] @ localhost [] # Query_time: 3.628924 Lock_time: 0.000000 Rows_sent: 0 Rows_examined: 0 SET timestamp=1268999330; commit; # User@Host: username[username] @ localhost [] # Query_time: 3.116018 Lock_time: 0.000000 Rows_sent: 0 Rows_examined: 0 ... Usually 6-7 "commit" queries in sequence. Anyone what they are and what's the preceding query of each of them? Thanks in advance.

• Which event handler to use to record leaving page - onunload or onbeforeunload?

  - by symcbean

  Hi all, Having not any answers to my previous questions about using javascript to measure page turn times, I'm going to start writing my own code (!). To measure the length of tie it takes, I'm proposing dropping a cookie containing a timestamp when the user browses away from a page, then in a subsequent page, comparing that time with 'now' and sending back a request to a URL which will log the interval. It seems that there are 2 possible handlers I could associate the first block of code with - the onunload() handler or the onbeforeunload()? It's more important that it fail silently on browsers with no/broken support for the handler, than it be portable across every possible browser. Any pointers? Gotchas? TIA C.

  Dear All, I recently started using Mac OS X for a flex/actionscript project and having a problem with flash player debugger plugin for the browsers: OSX: 10.6.3 Browsers I tried: firefox, safari and chrome Flashplayer debug "Flash Player 10 Plugin content debugger (Intel-based Macs) Whenever I open a page containing a flash content, my browser crashes due to flash player plugin's crash. I checked the version of my flash player debug plugin with http://kb2.adobe.com/cps/155/tn_15507.html and as the version checker is written in flash, my browser crashes a few seconds later.

• Writing a telnet client

  - by MAC

  HI, I have a device that exposes a telnet interface which you can log into using a username and password and then manipulate the working of the device. I have to write a C program that hides the telnet aspect from the client and instead provides an interface for the user to control the device. What would be a good way to proceed. I tried writing a simple socket program but it stops at the login prompt. My guess is that i am not following the TCP protocol. Has anyone attempted this, is there an opensource library out there to do this? Thanks

• How can I get PHP to compile a LaTeX document if it (www-data) can't get access to the required packages?

  - by Mark Jones

  I have a PHP script that compiles LaTeX documents with the use of: exec('cd /path/to/doc && /usr/bin/latexmk -pdf filename.tex'); This is working for some of my LaTeX documents but my latest document doesn't compile and a look at the log reveals: !pdfTeX error: pdflatex (file ecrm1000): Font ecrm1000 at 600 not found ==> Fatal error occurred, no output PDF file produced! Which I have found is the result of LaTeX not being able to see the required font packages. When I run the same compile command under my username the document compiles as it should. So my question is, how can I get PHP (executing as www-data) to get access to the necessary LaTeX packages? I have tried installing the required package under the www-data account using: sudo -u www-data sudo apt-get install texlive-fonts-recommended but it askes for www-data's password, which I don't believe was set by me and isn't anything I've thrown at it. I'm running Ubuntu 12.04 if it's any help.

• Return highest number found in an array of strings

  - by Mdd

  I have an array of objects. The objects have a property called level that is a string which contains a number and is in consistent format. I am trying to find the highest number and return just that one but I seem to be blocked as far as how to proceed from my current code. Here is a fiddle to my current code: http://jsfiddle.net/6sXYR/ Here is my JavaScript: var myArray = [ { color: 'blue', level: 'L1' }, { color: 'red', level: 'L1' }, { color: 'green', level: 'L2' }, { color: 'yellow', level: 'L2' }, { color: 'purple', level: 'L3' } ]; for (var i = 0; i < myArray.length; i++) { console.log( myArray[i].level.substring(1,2) ); }; The result I am trying to get is to return just the number '3' from the example above. The highest number may not always be in the last object in the array, but it will always be in the format of L#.

• Listener to prevent System.out display on the screen.

  - by harshit

  Hi, I was doing my academic project and while building and testing i have put many println() statements. But when I had to submit all prints should not be displayed. Can i implement something like listener which will be invoked when System.out is tried to be executed and prevents it from displaying. I dont know how feasible this idea is but just want to know whether its possible or not. I know i could have used a log file or write into a file but again its just a thought came into my mind if I have to disable SOP how can i do it .. thanks

• JavaScript on Android randomly stops working

  - by AndersWid

  Hi! I have an application that uses a WebView and a html-page with javascript functions. Randomly the JavaScript functions doesn't seem to be called. It works up to a random point (I have looked at this bug all day) can only be produced on hardware (HTC Legend) not on emulator. Basicly I'm using callback to javaScript whenever the user presses a button, these callbacks tell the html to redraw using javaScript functions. mHandler.post(new Runnable() { public void run() { mWebView.loadUrl("javascript:getDataLine()"); } }); The first line in this javaScript code is an alert that says that it has started, so that I can see that it's working. Settings alerts or console.log's everywhere won't help as it seems the problem is in the webview or in Android itself. I need a way to see what's going on in the background. Maybe see if a previous call failed and stalled the thread or something.

• node.js with SQL Server Native Client 11 scope_identity not being returned

  - by binderbound

  I'm having trouble with inserting a value into a database through node.js. Here is the offending code: sql.query(conn_str ,"INSERT INTO Login(email, hash, salt, firstName, lastName) VALUES(?, ?, ?, ?, ?); SELECT SCOPE_IDENTITY() AS 'Identity';" , [email, hash, salt, firstName, lastName], function(err, results){ console.log(results) } Unfortunately, the console is just echoing [], meaning results is an empty array, I suppose. Does anyone know why the identity is not being returned? Even if it was null, why isn't results then [{Identity: null }] ? Database is on Azure, which does have a "Scope_Identity" function, and the native client also recognises this function. Using node package "msnodesql" Please Help

• Help getting ActiveScaffold to work properly

  - by x3ro

  Hey there I was curious about the ActiveScaffold Rails plugin, but somehow I can't get it to work properly. I've followed the steps which are described on http://activescaffold.com/tutorials/ . The table and everything shows up and when I click on "Create new", the dialog pops up. However, when I fill out the form and click "Create", I just get "500 Internal server error". In the server log, it says "NameError (wrong constant name ###):", with ### being what I entered in the first form field. If I don't enter anything in the form, it says "NoMethodError (undefined method `new_record?' for #):"... So what am I doing wrong here? Thanks in advance for your help :)

• Set Java Application's virtual machine max memory without access to VM parameters because of custom

  - by Tom

  I'm using a Java application which allows you to import custom files. On import, these files are loaded into memory. The problem is that the files I want to import are very big, this causes an OutOfMemory exception. The crash log also informs me that the VM was started with the java parameter "-Xmx512m", I want to alter this to "-Xmx1024m" so that I got double the memory available. The problem is that this application is using it's own JRE folder and that there's a launcher written in C which is calling the jvm.dll file. In any way, java.exe or javaw.exe are never called and thus I cannot set these parameters myself (if I delete these executables it doesn't matter, can still run the application - this is not the case with the dll). So, my question is, can I set this VM parameter in an other way? I'm even willing to alter the JRE files if there is no other way.

• How to configure grails and shiro to mark cookies secure?

  - by j4y

  I'm using Grails 2.2.4 with the Shiro plugin (v1.1.4) and would like to mark the cookies as secure so the session information won't be sent over http. This is the attribute I want to set: securityManager.sessionManager.sessionIdCookie.secure = true The shiro source says to use the Grails bean property override mechanism, which is grails-app/conf/spring/resources.groovy How can I override just the one setting? // If the legacy 'security.shiro.filter.config' option is set, // use our custom INI-based filter... if (application.config.security.shiro.filter.config) { log.warn "security.shiro.filter.config option is deprecated. Use Grails' bean property override mechanism instead."

• Python fCGI + sqlAlchemy = malformed header from script. Bad header=FROM tags : index.py

  - by crgwbr

  I'm writing an Fast-CGI application that makes use of sqlAlchemy & MySQL for persistent data storage. I have no problem connecting to the DB and setting up ORM (so that tables get mapped to classes); I can even add data to tables (in memory). But, as soon as I query the DB (and push any changes from memory to storage) I get a 500 Internal Server Error and my error.log records malformed header from script. Bad header=FROM tags : index.py, when tags is the table name. Any idea what could be causing this? Also, I don't think it matters, but its a Linux development server talking to an off-site (across the country) MySQL server.

• How the hell do you get clients to use your bug tracking system?

  - by louism

  on larger projects i use a simple bug tracking system thats designed to be used by clients i have a lot of trouble convincing clients to use it (they send bug reports via email) does anyone have any strategies they can suggested? also, i have been playing around with a theory as to why this is the case; it goes like this: asking a client to log a bug is like taking your car to a mechanic for a service, and the mechanic hands you the engine oil and says "here, pop that in". basically, the client has paid you to do the work, logging a bug sounds too much like work, so they want you to do it thoughts? -- LM

  what kind of logging frame work or API to use for swing applications which is used by multiple users in Unix. Is it possible to log all verbose/exception in one file per day or event one user one file per day? Since the user can open the same application with multiple instance.
