  just installed mongokit and can't figure out why I get AssertionError python console: >>> from mongokit import Connection >>> c = Connection() Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python2.6/dist-packages/mongokit-0.5.3-py2.6.egg/mongokit/connection.py", line 35, in __init__ super(Connection, self).__init__(*args, **kwargs) File "build/bdist.linux-i686/egg/pymongo/connection.py", line 169, in __init__ File "build/bdist.linux-i686/egg/pymongo/connection.py", line 338, in __find_master File "build/bdist.linux-i686/egg/pymongo/connection.py", line 226, in __master File "build/bdist.linux-i686/egg/pymongo/database.py", line 220, in command File "build/bdist.linux-i686/egg/pymongo/collection.py", line 356, in find_one File "build/bdist.linux-i686/egg/pymongo/cursor.py", line 485, in next File "build/bdist.linux-i686/egg/pymongo/cursor.py", line 461, in _refresh File "build/bdist.linux-i686/egg/pymongo/cursor.py", line 429, in __send_message File "build/bdist.linux-i686/egg/pymongo/helpers.py", line 98, in _unpack_response AssertionError >>> mongodb console: Wed Mar 31 10:27:34 connection accepted from 127.0.0.1:60480 #30 Wed Mar 31 10:27:34 end connection 127.0.0.1:60480 db 1.5 pymongo 1.5 (tested also on 1.4.) mongokit 0.5.3 (also 0.5.2)

• Why does Perl's DBI complain about "failed: ERROR OCIEnvNlsCreate" when I try to connect to Oracle 1

  - by John

  I am getting the following error connecting to an Oracle 11g database using a simple Perl script: failed: ERROR OCIEnvNlsCreate. Check ORACLE_HOME (Linux) env var or PATH (Windows) and or NLS settings, permissions, etc. at The script is as follows: #!/usr/local/bin/perl use strict; use DBI; if ($#ARGV < 3) { print "Usage: perl testDbAccess.pl dataBaseUser dataBasePassword SID dataBasePort\n"; exit 0; } my ($user, $pwd, $sid, $port) = @ARGV; my $host = `hostname`; my $dbh; my $sth; my $dbname = "dbi:Oracle:HOST=$host;SID=$sid;PORT=$port"; openDbConnection(); closeDbConnection(); sub openDbConnection() { $dbh = DBI->connect ($dbname, $user ,$pwd , { RaiseError => 1}) || die "Database connection not made: $DBI::errstr"; } sub closeDbConnection() { #$sth->finish(); $dbh->disconnect(); } Anyone seen this problem before?

• Calculate the digital root of a number

  - by Gregory Higley

  A digital root, according to Wikipedia, is "the number obtained by adding all the digits, then adding the digits of that number, and then continuing until a single-digit number is reached." For instance, the digital root of 99 is 9, because 9 + 9 = 18 and 1 + 8 = 9. My Haskell solution -- and I'm no expert -- is as follows. digitalRoot n | n < 10 = n | otherwise = digitalRoot . sum . map (\c -> read [c]) . show $ n As a language junky, I'm interested in seeing solutions in as many languages as possible, both to learn about those languages and possibly to learn new ways of using languages I already know. (And I know at least a bit of quite a few.) I'm particularly interested in the tightest, most elegant solutions in Haskell and REBOL, my two principal "hobby" languages, but any ol' language will do. (I pay the bills with unrelated projects in Objective C and C#.) Here's my (verbose) REBOL solution: digital-root: func [n [integer!] /local added expanded] [ either n < 10 [ n ][ expanded: copy [] foreach c to-string n [ append expanded to-integer to-string c ] added: 0 foreach e expanded [ added: added + e ] digital-root added ] ] EDIT: As some have pointed out either directly or indirectly, there's a quick one-line expression that can calculate this. You can find it in several of the answers below and in the linked Wikipedia page. (I've awarded Varun the answer, as the first to point it out.) Wish I'd known about that before, but we can still bend our brains with this question by avoiding solutions that involve that expression, if you're so inclined. If not, Crackoverflow has no shortage of questions to answer. :)

• Slow Python HTTP server on localhost

  - by Abiel

  I am experiencing some performance problems when creating a very simple Python HTTP server. The key issue is that performance is varying depending on which client I use to access it, where the server and all clients are being run on the local machine. For instance, a GET request issued from a Python script (urllib2.urlopen('http://localhost/').read()) takes just over a second to complete, which seems slow considering that the server is under no load. Running the GET request from Excel using MSXML2.ServerXMLHTTP also feels slow. However, requesting the data Google Chrome or from RCurl, the curl add-in for R, yields an essentially instantaneous response, which is what I would expect. Adding further to my confusion is that I do not experience any performance problems for any client when I am on my computer at work (the performance problems are on my home computer). Both systems run Python 2.6, although the work computer runs Windows XP instead of 7. Below is my very simple server example, which simply returns 'Hello world' for any get request. from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer class MyHandler(BaseHTTPRequestHandler): def do_GET(self): print("Just received a GET request") self.send_response(200) self.send_header("Content-type", "text/html") self.end_headers() self.wfile.write('Hello world') return def log_request(self, code=None, size=None): print('Request') def log_message(self, format, *args): print('Message') if __name__ == "__main__": try: server = HTTPServer(('localhost', 80), MyHandler) print('Started http server') server.serve_forever() except KeyboardInterrupt: print('^C received, shutting down server') server.socket.close() Note that in MyHandler I override the log_request() and log_message() functions. The reason is that I read that a fully-qualified domain name lookup performed by one of these functions might be a reason for a slow server. Unfortunately setting them to just print a static message did not solve my problem. Also, notice that I have put in a print() statement as the first line of the do_GET() routine in MyHandler. The slowness occurs prior to this message being printed, meaning that none of the stuff that comes after it is causing a delay.

• iPhone AVAudioPlayer failed to find codec

  - by Anthony

  Hello, I am writing an app that downloads a wav file from a server and needs to play that file. The files use the mulaw codec with 2:1 compression. These wav files are dynamically created by a seperate process so there is no way for me to preconvert the files to a different format or codec, I need to be able to play them as is. I am using an AVAudioPlayer instance initialized as follows: NSURL *audioURL = [[NSURL alloc] initWithString:@"http://xxx.../file.wav"]; NSData *audioData = [[NSData alloc] initWithContentsOfURL:audioURL]; AVAudioPlayer *audio = [[AVAudioPlayer alloc] initWithData:audioData error:nil]; [audio play]; However, when the play method executes, I get the following Console Output when executing on the Simulator: AudioQueue codec policy 1: failed to find a codec of the requested type I also tried saving the downloaded data to a local file and using a file URL, however that yeilds the same results. The downloaded file does play fine on both Mac and Windows based desktop media players. The SDK docs state that the mulaw codec is supported on the iPhone, so I am unsure why it is failing to find it. Any assistance would be greatly appreciated. Thanks.

• Web page database query optimization

  - by morpheous

  I am putting together a web page which is quite 'expensive' in terms of database hits. I don't want to start optimizing at this stage - though with me trying to hit a deadline, I may end up not optimizing at all. Currently the page requires 18 (that's right eighteen) hits to the db. I am already using joins, and some of the queries are UNIONed to minimize the trips to the db. My local dev machine can handle this (page is not slow) however, I feel if I release this into the wild, the number of queries will quickly overwhelm my database (MySQL). I could always use memcache or something similar, but I would much rather continue with my other dev work that needs to be completed before the deadline - at least retrieving the page works - its simply a matter of optimization now (if required). My question therefore is - is 18 db queries for a single page retrieval completely outrageous - (i.e. I should put everything on hold and optimize the hell of the retrieval logic), or shall I continue as normal, meet the deadline and release on schedule and see what happens? [Edit] Just to clarify, I have already done the 'obvious' things like using (single and composite) indexes for fields used in the queries. What I haven't yet done is to run a query analyzer to see if my indexes etc are optimal.

• Limiting ssh user account only to access his home directory!

  - by EBAGHAKI

  By reading some tutorials online I used these commands: Make a local group: net localgroup CopsshUsers /ADD Deny access to this group at top level: cacls c:\ /c /e /t /d CopsshUsers Open access to the copSSH installation directory: cacls copssh-inst-dir /c /e /t /r CopsshUsers Add Copssh user to the group above: net localgroup CopsshUsers mysshuser /add simply put these commands will try to create a usergroup that has no permission on your computer and it only have access to the copSSH Installation directory. This is not true, since you cannot change the permission on your windows directory, the third command won't remove access to windows folder (it says access denied on his log). Somehow I achieved that by taking ownership of Windows folder and then i execute the third command so CopsshUsers has no permissions on windows folder from now on. Now i tried to SSH to the server and it simply can't login! this is kind of funny because with permission on windows directory you can login and without it you can't!! So if you CAN SSH to the server somehow you know that you have access to the windows directory! (Is this really true??) Simple task: Limiting ssh user account only to access his home directory on WINDOWS and nothing else! Guys please help!

• TortoiseSVN lists files as modified, but they are identical

  - by BJ Safdie

  I am merging a hot fix from our QA branch back into our Dev branch. Five files have changed. I do a fresh checkout of the Dev branch. I then do a merge (range of revisions) from QA into the Dev working copy. It brings in five files and there is a conflict on an external and ignore property -- which I resolve by "using local" (dev). When I check modifications or commit, I expect to see the five files I merged as the only changes. However, I get close to 700 "modified" files showing up in the commit dialog. If I select one of these file and "Compare with base," WinMerge comes up and says the "files are identical." I have tried this with the file dates set to "last committed" and not. Why are all of these files showing up as modified, when they are identical? What in the merge is causing this? How do I prevent SVN/TortoiseSVN from getting confused this way in the future?

• Where did Pylons beautiful error handling go? Using Nginx + Paster + Flup#fcgi_thread

  - by Tony

  I need to run my development through nginx due to some complicated subdomain routing rules in my pylons app that wouldn't be handled otherwise. I had been using lighttpd + paster + Flup#scgi_thread and the nice error reporting by Pylons had been working fine in that environment. Yesterday I recompiled Python and MySQL for 64bit, and also switched to Ngix + paster + Flup#fcgi_thread for my development environment. Everything is working great, but I miss the fancy error reports. This is what I get now, and it is a mess compared to what I got used to: http://drp.ly/Iygeg . And here are the pylons/nginx configs. Pylons: [server:main] use = egg:Flup#fcgi_thread host = 0.0.0.0 port = 6500 Nginx: location / { #include /usr/local/nginx/conf/fastcgi.conf; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param QUERY_STRING $query_string; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_pass_header Authorization; fastcgi_intercept_errors off; fastcgi_pass 127.0.0.1:6500; }

• Version Control: multiple version hell, file synchronization

  - by SigTerm

  Hello. I would like to know how you normally deal with this situation: I have a set of utility functions. Say..5..10 files. And technically they are static library, cross-platform - SConscript/SConstruct plus Visual Studio project (not solution). Those utility functions are used in multiple small projects (15+, number increases over time). Each project has a copy of a few files or of an entire library, not a link into one central place. Sometimes project uses one file, two files, some use everything. Normally, utility functions are included as a copy of every file and SConscript/SConstruct or Visual Studio Project (depending on the situation). Each project has a separate git repository. Sometimes one project is derived from other, sometimes it isn't. You work on every one of them, in random order. There are no other people (to make things simpler) The problem arises when while working on one project you modify those utility function files. Because each project has a copy of file, this introduces new version, which leads to the mess when you try later (week later, for example) to guess which version has a most complete functionality (i.e. you added a function to a.cpp in one project, and added another function to a.cpp in another project, which created a version fork) How would you handle this situation to avoid "version hell"? One way I can think of is using symbolic links/hard links, but it isn't perfect - if you delete one central storage, it will all go to hell. And hard links won't work on dual-boot system (although symbolic links will). It looks like what I need is something like advanced git repository, where code for the project is stored in one local repository, but is synchronized with multiple external repositories. But I'm not sure how to do it or if it is possible to do this with git. So, what do you think?

• Trouble extending event log messages

  - by Matt H

  Hi. I'm trying to add some extended error codes to the event log but I get the following error. The description for Event ID ( 109 ) in Source ( PumpServer ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: The event log file is corrupt.. The message file looks like this and I added the one on the end:- <---snip---> MessageId= SymbolicName=EVMSG_BADREQUEST Language=English The service received an unsupported request. . MessageId= SymbolicName=EVMSG_DEBUG Language=English %1 . MessageId= SymbolicName=EVMSG_STOPPED Language=English The service was stopped. . MessageId= SymbolicName=EVMSG_INVALIDLICENCE Language=English The service does not have a valid licence. Initialization failed. . It compiles fine. The mc program is running over this file and producing a header file of the same name with my new message id showing. // // MessageId: EVMSG_INVALIDLICENCE // // MessageText: // // The service does not have a valid licence. Initialization failed. // #define EVMSG_INVALIDLICENCE 0x0000006DL Any ideas why it's not finding my message? All the others work.

• PHP & cUrl - POST problems in while loop.

  - by Max Hoff

  I have a while loop, with cUrl inside. (I can't use curl_multi for various reasons.) The problem is that cUrl seems to save the data it POSTS after each loop traversal. For instance, if parameter X is One the first loop through, and if it's Two the second loop through, cUrl posts: "One,Two". It should just POST "Two".(This is despite closing and unsetting the curl handle.) Here's a simplified version of the code (with unecessary info stripped out): while(true){ // code to form the $url. this code is local to the loop. so the variables should be "erased" and made new for each loop through. $ch = curl_init(); $userAgent = 'Googlebot/2.1 (http://www.googlebot.com/bot.html)'; curl_setopt($ch,CURLOPT_USERAGENT, $userAgent); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_POST,count($fields)); curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string); curl_setopt($ch, CURLOPT_FAILONERROR, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_AUTOREFERER, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER,true); curl_setopt($ch, CURLOPT_TIMEOUT, 10); $html = curl_exec($ch); curl_close($ch); unset($ch); $dom = new DOMDocument(); @$dom->loadHTML($html); $xpath = new DOMXPath($dom); $resultTable = $xpath->evaluate("/html/body//table"); // $resultTable is 20 the first time through the loop, and 0 everytime thereafter becauset he POSTing doesn't work right with the "saved" parameters. What am I doing wrong here?

• rails Rake and mysql ssh port forwarding.

  - by rube_noob

  Hello, I need to create a rake task to do some active record operations via a ssh tunnel. The rake task is run on a remote windows machine so I would like to keep things in ruby. This is my latest attempt. desc "Syncronizes the tablets DB with the Server" task(:sync => :environment) do require 'rubygems' require 'net/ssh' begin Thread.abort_on_exception = true tunnel_thread = Thread.new do Thread.current[:ready] = false hostname = 'host' username = 'tunneluser' Net::SSH.start(hostname, username) do|ssh| ssh.forward.local(3333, "mysqlhost.com", 3306) Thread.current[:ready] = true puts "ready thread" ssh.loop(0) { true } end end until tunnel_thread[:ready] == true do end puts "tunnel ready" Importer.sync rescue StandardError => e puts "The Database Sync Failed." end end The task seems to hang at "tunnel ready" and never attempts the sync. I have had success when running first a rake task to create the tunnel and then running the rake sync in a different terminal. I want to combine these however so that if there is an error with the tunnel it will not attempt the sync. This is my first time using ruby Threads and Net::SSH forwarding so I am not sure what is the issue here. Any Ideas!? Thanks

• using volatile keyword

  - by sap

  As i understand, if we declare a variable as volatile, then it will not be stored in the local cache. Whenever thread are updating the values, it is updated to the main memory. So, other threads can access the updated value. But in the following program both volatile and non-volatile variables are displaying same value. The volatile variable is not updated for the second thread. Can anybody plz explain this why testValue is not changed. class ExampleThread extends Thread { private int testValue1; private volatile int testValue; public ExampleThread(String str){ super(str); } public void run() { if (getName().equals("Thread 1 ")) { testValue = 10; testValue1= 10; System.out.println( "Thread 1 testValue1 : " + testValue1); System.out.println( "Thread 1 testValue : " + testValue); } if (getName().equals("Thread 2 ")) { System.out.println( "Thread 2 testValue1 : " + testValue1); System.out.println( "Thread 2 testValue : " + testValue); } } } public class VolatileExample { public static void main(String args[]) { new ExampleThread("Thread 1 ").start(); new ExampleThread("Thread 2 ").start(); } } output: Thread 1 testValue1 : 10 Thread 1 testValue : 10 Thread 2 testValue1 : 0 Thread 2 testValue : 0

• Why does one of these statements compile in Scala but not the other?

  - by Jeff

  (Note: I'm using Scala 2.7.7 here, not 2.8). I'm doing something pretty simple -- creating a map based on the values in a simple, 2-column CSV file -- and I've completed it easily enough, but I'm perplexed at why my first attempt didn't compile. Here's the code: // Returns Iterator[String] private def getLines = Source.fromFile(csvFilePath).getLines // This doesn't compile: def mapping: Map[String,String] = { Map(getLines map { line: String => val pairArr = line.split(",") pairArr(0) -> pairArr(1).trim() }.toList:_*) } // This DOES compile def mapping: Map[String,String] = { def strPair(line: String): (String,String) = { val pairArr = line.split(",") pairArr(0) -> pairArr(1).trim() } Map(getLines.map( strPair(_) ).toList:_*) } The compiler error is CsvReader.scala:16: error: value toList is not a member of (St ring) = (java.lang.String, java.lang.String) [scalac] possible cause: maybe a semicolon is missing before `value toList'? [scalac] }.toList:_*) [scalac] ^ [scalac] one error found So what gives? They seem like they should be equivalent to me, apart from the explicit function definition (vs. anonymous in the nonworking example) and () vs. {}. If I replace the curly braces with parentheses in the nonworking example, the error is "';' expected, but 'val' found." But if I remove the local variable definition and split the string twice AND use parens instead of curly braces, it compiles. Can someone explain this difference to me, preferably with a link to Scala docs explaining the difference between parens and curly braces when used to surround method arguments?

• Dependency Property ListBox

• Import CSV to mysql

  - by 404error

  I have created a database and table. I have also created all the fields i will be needing. I have created 46 fields including 1 that is my ID for the row. The CSV doesn't contain the id field, nor does it contain the headers for the columns. I am new to all of this but have been trying to figure this out. I'm not on here being lazy asking for the answer, but looking for direction. I'm trying to figure out how to import the CSV but have it start importing data starting at the 2nd field, since I'm hoping the auto_increment will fill in the ID field, which is the first field i created. I tried these instructions with now luck. Can anyone offer some insight? your cvs file's column name must match your table column name browse your required .csv file select CSV using LOAD DATA options Check box 'ON' for Replace table data with file in Fields terminated by box type , in Fields enclosed by box " in Fields escaped by box \ in Lines terminated by box auto in Column names box type column name seperated by , like column1,column2,column3 10 check box ON for Use LOCAL keyword.

• Connecting to database on web host in Visual Studio

  - by Anders Svensson

  I have a web site developed locally with a local Sql Server database. I also have a web host that provides one Sql Server database for my site. Now I want to deploy the application, and I would like to be able to manage the remote database from the Server Explorer in Visual Studio. I have the connection string used in the application, which works fine for adding, say, a datasource to a control etc. But I don't know if there's any way to use it to connect the database inside the Server Explorer so that I can add tables etc. I have read that you're supposed to be able to this instead of using the Sql Server Management Studio, but I have'nt read anything about how to connect to the remote database in it. What I have tried so far is this: I have selected Add database in Server Explorer. This brings up first a dialog where I choose Sql Server. And then I get a dialog where I can set Server name (which I tried using the ip address in the connection string below), and Authentication (where I chose Sql Server Authentication, with the user id and password from below). But when I test the connection it fails. Here's the connection string, which works fine when used for datasources in the application (obviously with different user name and password): Any help appreciated!

  Hi all, I have the following situation: I have class User with the follwing properies : public class User { string user name ; List <Contact> contacts ; List <BookMark> book marks; . . . } I have the same class in a different namespace , with some different properties . BWT , it's the same situation of it's classes (Contact) and (BookMark). I need to make a deep copy of the same properties from the two classes . Actually , I arrive to this situation by having an Entity Framework edmx file . I created the first database (SQL server 2008) from this model . And copied he same edmx file to another project and created the database with SQL CE db. Now I get the first data model objects by WCF service and need to persist them in the local database in my application . The objects are the same but there are some changs because of the modeling issue with a different databse. Do you have any workarround about this assue. Thanks in advance ...

• How to get an enum value from an assembly using late binding in C#

  - by tetranz

  Hello I have a C# 3.0 WinForms application which is occasionally required to control Excel with automation. This is working nicely with normal early binding but I've had some problems when people don't have Excel installed but still want to use my app except for the Excel part. Late binding seems to be a solution to this. Late binding is rather tedious in C# 3 but I'm not doing anything particularly difficult. I'm following http://support.microsoft.com/kb/302902 as a starter and it's working out well. My question is how can I use an enum by name? e.g, how can I use reflection to get the value of Microsoft.Office.Interop.Excel.XlFileFormat.xlTextWindows so that I can use it an InvokeMethod call? I know the easiest way is probably to create my own local enum with the same "magic" integer value but it would be nicer to be able to access it by name. The docs often don't list the value so to get it I probably need to have a little early bound test app that can tell me the value. Thanks

• How can I automatically elevate a COM interface used for automation?

  - by Jim Flood

  I have a Windows service built with ATL to expose a LocalServer32 COM interface for a set of admin commands used for configuring the service, and these can be used from VBScript for example: Set myObj = WScript.CreateObject("MySvc.Administrator") myObj.DoSomething() I want DoSomething to run elevated, and I would like the UAC prompt to come up automatically when this is called by the VBScript. Is this possible? I know I can run the script in an elevated command shell, and that I can use objShell.ShellExecute WScript.FullName, Chr(34) & WScript.ScriptFullName & Chr(34), vbNullString, "runas" for example, to run the VBScript itself elevated, and either of those work fine -- the COM method finds itself elevated. However, AFAIK getting an elevated Explorer window on the desktop is convoluted (it's not as simple as right-clicking Start/Accessories/Windows Explorer/Run as Administrator, which doesn't actually elevate.) I want a user in the local admin group to be able to drag-and-drop files and folders onto the script, and then have the script call the admin COM interface with those pathnames as arguments. (And I am hoping for something simpler than monkeying around with the args and using ShellExecute "runas".) I've tried setting UAC Execution Level to requireAdministrator in the service EXE's manifest, and setting Elevated/Enabled = 1 and LocalizedString in the registry for the MySvc.Administrator class, and these don't do the trick.

• String Length Evaluating Incorrectly

  My coworker and I are debugging an issue in a WCF service he's working on where a string's length isn't being evaluated correctly. He is running this method to unit test a method in his WCF service: // Unit test method public void RemoveAppGroupTest() { string addGroup = "TestGroup"; string status = string.Empty; string message = string.Empty; appActiveDirectoryServicesClient.RemoveAppGroup("AOD", addGroup, ref status, ref message); } // Inside the WCF service [OperationBehavior(Impersonation = ImpersonationOption.Required)] public void RemoveAppGroup(string AppName, string GroupName, ref string Status, ref string Message) { string accessOnDemandDomain = "MyDomain"; RemoveAppGroupFromDomain(AppName, accessOnDemandDomain, GroupName, ref Status, ref Message); } public AppActiveDirectoryDomain(string AppName, string DomainName) { if (string.IsNullOrEmpty(AppName)) { throw new ArgumentNullException("AppName", "You must specify an application name"); } } We tried to step into the .NET source code to see what value string.IsNullOrEmpty was receiving, but the IDE printed this message when we attempted to evaluate the variable: 'Cannot obtain value of local or argument 'value' as it is not available at this instruction pointer, possibly because it has been optimized away.' (None of the projects involved have optimizations enabled). So, we decided to try explicitly setting the value of the variable inside the method itself, immediately before the length check -- but that didn't help. // Lets try this again. public AppActiveDirectoryDomain(string AppName, string DomainName) { // Explicitly set the value for testing purposes. AppName = "AOD"; if (AppName == null) { throw new ArgumentNullException("AppName", "You must specify an application name"); } if (AppName.Length == 0) { // This exception gets thrown, even though it obviously isn't a zero length string. throw new ArgumentNullException("AppName", "You must specify an application name"); } } We're really pulling our hair out on this one. Has anyone else experienced behavior like this? Any tips on debugging it?

• How do I generate a connection reset programatically?

  - by Brock Adams

  Hi, I'm sure you've seen the "the connection was reset" message displayed when trying to browse web pages. (The text is from Firefox, other browsers differ.) I need to generate that message/error/condition on demand, to test workarounds. So, how do I generate that condition programmatically? (How to generate a TCP RST from PHP -- or one of the other web-app languages?) Caveats and Conditions: It cannot be a general IP block. The test client must still be able to see the test server when not triggering the condition. Ideally, it would be done at the web-application level (Python, PHP, Coldfusion, Javascript, etc.). Access to routers is problematic. Access to Apache config is a pain. Ideally, it would be triggered by fetching a specific web-page. Bonus if it works on a standard, commercial web host. Update: Sending RST is not enough to cause this condition. See my partial answer, below. I've a solution that works on a local machine, Now need to get it working on a remote host.

• Ultra-Portable Laptop or Tablet PC for Development and Sketching

  - by Nelson LaQuet

  I am a software developer that primarily writes in PHP, [X]HTML, CSS, Javascript, C# and C++. I use Eclipse for web development, Visual Studio 2008 for C++ and C# work, TortoiseSVN, Subversion server for local repositories, SQL Server Express, Apache and MYSQL. I also use Office 2007 for word processing and spreadsheets and use Vista Ultimate 64 as my primary operating system. The only other things I do on my laptop are watch movies, surf the internet and listen to music. I currently have a Acer Aspire 5100 (1.4 GHz AMD Turion X2, 2 GB of RAM and a 15.4" screen). This thing does not cut it in performance or portability, and in addition, my DVD drive failed. And before anybody posts about vista: I have had XP Professional 32 on it for the last two years, and recently upgraded to Vista 64. It is actually faster (with areo disabled) then XP; so it is not the OS that is causing the laptop to be slow. I usually sketch a lot, for explaining things, developing user interfaces and software architecture. Because of my requirements, I was thinking about a Lenovo X61 Tablet PC. It outperforms my current laptop, is significantly more portable, and... is a tablet. My question is: do any other software developers use this (or other tablets) for programming? Does it help to be able to sketch on the computer itself? And is it capable of being a good development machine? Will it handle the above software listed? If not, what is the best ultra-portable laptop that is good for programming? Or are ultra-portable laptops even good for programming? I could manage with my 15.4" screen, but am spoiled by my two 19" at my home desktop and my job's workstation.

• Very weird C file-handling anomaly

  - by KáGé

  Hello, I got a very weird issue that I cant figure out in my school project, which is the simulation of a simple filesystem in a human-readable textfile. Unfortunately I don't yet have enough time to translate the comments in my code or make it less gibberish, so if you are bothered by that, you don't have to help, I understand. See the code HERE. Now in drive.h, at line 574 is this part: i = getline(); #ifdef DEBUG printf("Free space in all found at %d.\n\n", i); if(drive.disk != NULL){ printf("Disk OK\n\n"); } #endif //write in data state = seekline(i); Before this it finds place for the allocation database entry in the ALL sector (see the "image files" in the mounts folder, this issue was tested on mount_30.efs-dbf), then gets the line with i = getline() fine (getline is in lglobal.h, line 39), but after that any file manipulation (in this case seekline's fseek, but if I comment that out, then the first fprintf after that) crashes the program straight away. I think the file gets somehow corrupted (though the Disk OK message appears) but can't figure out how. I've tried putting i = getline(); into comment, but it didn't make any difference. I've also tried asking at local programming forums but they didn't really help either. The last few lines of the output before it crashes: Dir written. (drive.h line 562) Seekline entered: 268 (called at drive.h line 564) Getline entered. (called at drive.h line 574) Line got: 268. Free space in all found at 268. (drive.h line 576) Seekline entered: 268 (called at drive.h line 582, note that this exact call was run successfully less than 20 lines back. This one should set the pointer to the beginning of the line it is currently in) After this it crashes. Does anyone has any idea of what causes this and how could I fix it? Thank you.
