• Configure Mouse Buttons for "Administrator"/Elevated privileges

  - by Zhaph - Ben Duguid

  I am, for better or worse, an administrator on my Windows 7 machine. However, even then, I still need to run certain programs "as Administrator" - for example, Visual Studio 2008 when working with local IIS sites. I also like to have the extra buttons on my IntelliMouse Optical doing non-standard things, like representing Ctrl and Shift. However, when in VS running as administrator, these settings aren't picked up, just like my mapped drives aren't picked up - I would understand this if I was logging in as a different user, supplying credentials, etc, but I'm not, I'm just pressing "Yes" at the UAC prompt. Normally, I'd just right click the item in the start menu and select "Run as administrator", but that's not an option on the context menu for either the Microsoft IntelliPoint Mouse application that appears under "Programs", nor the "Mouse" control panel item. Running the control panel as administrator also doesn't seem to help. So has any one got any suggestions on how I can configure my mouse buttons for the elevated version of me that Visual Studio is running as?

• Mapping drives on MacOSX (Leopard/Snow Leopard) permanently inside LAN

  - by Shyam

  Hi, How do I "map" shared folders on a Mac, permanently? With map, I do not mean 'connect', but permanently add it to the system so it exists after reboot. Since workstations tend to shutdown, I wonder also the symptoms and cures in case that happens. In Linux, this can be done using the fstab file, but I noticed that volumes are mounted in a different structure than Linux. I need this to backup some workstations, doing a recursive job over a single directory, that should contain the shared folders. I use Terminal to access the main system, so by preference, the solution would be nice that works within a bash shell vs GUI. I can access all folders in Finder. Thanks!

• Replace text in word textbox objects using VSTO and C#

  - by Roberto

  Hi, I have to find/replace text from a word document. It works fine for plain text spread through the document, however when the text is in a textbox, the standard find/replace approach doesn't reach it. I found a vba solution, however since I am working in C#, I would like to find a solution in C#. The word document is in 2007 format and my visual studio is 2010. I am using .Net Framework 3.5, but if required, I can consider moving to 4.0. Here is the code for the find/replace that only works with plain text (not in word textbox objects): object Missing = System.Reflection.Missing.Value; object fileToOpen = (object)@"c:\doc.docx"; object fileToSave = (object)@"c:\doc.docx"; Word.Application app = new Word.ApplicationClass(); Word.Document doc = new Word.Document(); try { doc = app.Documents.Open(ref fileToOpen, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing); object replaceAll = Word.WdReplace.wdReplaceAll; app.Selection.Find.ClearFormatting(); app.Selection.Find.Text = "MyTextForReplacement"; app.Selection.Find.Replacement.ClearFormatting(); app.Selection.Find.Replacement.Text = "Found you!"; app.Selection.Find.Execute( ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref Missing, ref replaceAll, ref Missing, ref Missing, ref Missing, ref Missing); I also tried using the below code, but didn't work as well: foreach(Word.Shape s in app.ActiveDocument.Shapes) { if(s.TextFrame.HasText >= 1) //The value is always 0 or -1, and even leaving 0 go forward, // it doesn't work, because there is no text in there... { foreach(Word.Field f in s.TextFrame.TextRange.Fields) { switch( f.Type) { . . //I never reached this point . } } } Any help will be appreciated... Thanks, -- Roberto Lopes

• Math operations in nHibernate Criteria Query

  - by Richard Tasker

  Dear All, I am having troubles with a nHibernate query. I have a db which stores vehicle info, and the user is able to search the db by make, model, type and production dates. Make, model & type search is fine, works a treat, it is the productions dates I am having issues with. So here goes... The dates are stored as ints (StartMonth, StartYear, FinishMonth, FinishYear), when the end-user selects a date it is passed to the query as an int eg 2010006 (2010 * 100 + 6). below is part of the query I am using, FYI I am using Lambda Extensions. if (_searchCriteria.ProductionStart > 0) { query.Add<Engine>(e => ((e.StartYear * 100) + e.StartMonth) >= _searchCriteria.ProductionStart); } if (_searchCriteria.ProductionEnd > 0) { query.Add<Engine>(e => ((e.FinishYear * 100) + e.FinishMonth) <= _searchCriteria.ProductionEnd); } But when the query runs I get the following message, Could not determine member from ((e.StartYear * 100) + e.StartMonth) Any help would be great, Regards Rich

• Setting up multiple wireless access points on same network

  - by SqlRyan

  I'd like to add wireless to my network, and I need multiple access points to cover the whole area. I'd like to set them up so that there's only one "wireless network" that the clients see, and it switches them as seamlessly as possible between access points as they wander around (if that's not possible, then at least have it so that they don't need to set up the security by hand on each one the first time, if possible). I've searched online, and there are quite a few sets of mixed instructions (same vs different SSID, frequency, does the security need to match exactly, etc.). Can somebody who has some experience doing this please let me know what they did? I imagine it's pretty simple, but there seems to be no clear cut "yes, you can do this" online, even though I know you can. I have a mid-size LAN with about 20 workstations and two Domain Controllers on it. Also, I'll be doing this with consumer wireless components, if it makes a difference, not enterprise-level components (ie. Linksys rather than Cisco).

• Displaying shifts on a timetable/calendar using C#

  - by Dave Peters

  I am very much a beginner and have experience of SQL and a tiny amount of VBA. What I am looking to do is create a tool to pull shift times from a database and to display them on a timetable/calendar. It will be part of a desktop application that the (very tech illiterate) end users will use to view and amend shift patterns. In essence it will be a grid with days on one axis and people on the other (I would however like to have the blocks proportional to shift length). In my mind it would potentially be a simple Gantt chart. All computing stuff I’ve learnt has been through trial and error and I want to use this project to get a much better understanding of C# as well as to get to the end product. I have been reading around for ways to tackle the problem and my issue is creating the timetable framework to which I will bind the data. I am using Visual Studio 2010 and SQL Server 2008 R2. Do you know of good resources which will either start me on the road to designing my own interface or give a basic framework I can adapt? All the resources I’ve found so far have been in different languages or for web based applications. Thank you for your time.

• Windows 7 - Windows get autoselected

  - by DjRikyx

  I have a really annoying problem in Windows 7. I just updated Windows vista to Windows 7 32bit The problem is that every second the top windows is being selected. To explain better what happens: I open task manager and leave it there, then i select a icon on desktop, after 1 second, the icon is deselected and Task Manager windows is selected. Also i see windows borders blinking, every second. This is Annoying, because every time i do a right click or selecting a menu in any application, every second the menu get closed... I do not know what is doing this, i searched in task manager for some 'bad' application running, but seems ok, tried closing all programs but it's still there. If i restart the computer first i don't get that problem, but after a while it start.. I noticed that When using Visual Studio Express 2012, but i don't think is the problem, because also if i close VS the problem remains. Hope you can help me, i'm getting hungry!! It's annoying!

• WCF Service w/ SharePoint Error: Could not find default endpoint element that references contract...

  - by Brian Clark

  Full error message: Could not find default endpoint element that references contract 'PublicationServices.IPublicationService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element. I have a SharePoint site that I have already opened a project for in Visual Studio 2010. I also created a project that contains a WCF Service Application and added it to the same solution that contains the project for my SharePoint site. I have created a visual web part in my SharePoint project that I am trying to use to consume the WCF Service. I am doing so like this, from within the user control for my web part: PublicationServiceClient proxy = new PublicationServiceClient(); Just having this line alone in OnPreRender, Page_Load, etc. will generate the above error. I've read previous posts about having to have items in the config file of the WCF service also in the config file of the consuming application. I have done this, I copied this section the Web.config file in my WCF service and have placed it in the system.serviceModel tags of my SharePoint project's app.config file: In other words, this is in both of my config files. When I add this web part to the front page of my SharePoint site though, I get the above error every time. I should also note that I have created a console app that I was able to use with no problems to consume data from this very same WCF service. Any help would be appreciated!

• How to pass password text while calling Java CXF webservice from PHP

• GHC 6.12 and MacPorts

  - by absz

  I recently installed GHC 6.12 and the Haskell Platform 2010.1.0.1 on my Intel MacBook running OS X 10.5.8, and initially, everything worked fine. However, I discovered that if I use cabal install to install a package which depends on a MacPorts library (e.g., cabal install --extra-lib-dirs=/opt/local/lib --extra-include-dirs=/opt/local/include gd), things work fine in GHCi, but if I try to compile, I get the error Linking test ... Undefined symbols: "_iconv_close", referenced from: _hs_iconv_close in libHSbase-4.2.0.0.a(iconv.o) "_iconv", referenced from: _hs_iconv in libHSbase-4.2.0.0.a(iconv.o) "_iconv_open", referenced from: _hs_iconv_open in libHSbase-4.2.0.0.a(iconv.o) ld: symbol(s) not found collect2: ld returned 1 exit status After some Googling, I found a long Haskell-cafe thread discussing this problem. The upshot seems to be that MacPorts installs an updated version of libiconv, and the binary interface is slightly different from the version included with the system. Consequently, if you try to link with any MacPorts library, the MacPorts libiconv gets linked in too; and since the base library was built to link against a different version of libiconv, things break. I've tried setting LD_LIBRARY_PATH and DYLD_LIBRARY_PATH and adding more flags to try to get it to look at /usr/lib again (e.g. cabal install --extra-lib-dirs=/opt/local/lib --extra-include-dirs=/opt/local/include --extra-lib-dirs=/usr/lib --extra-include-dirs=/usr/include gd), but neither worked. Uninstalling the MacPorts libiconv isn't really an option, since I have a bunch of ports installed which depend on it---including some ports I want Haskell to link to, like gd2. From what I've seen online, the upshot really seems to be "you're boned": you cannot link against any MacPorts library while compiling with GHC, and there doesn't seem to be a solution. However, that thread was from the end of 2009, so I figure there's a chance that someone has a solution, workaround, ridiculous hack… anything, really. So: does anybody know how to get GHC 6.12 to link against the system libiconv at the same time as it links to libraries from MacPorts? Or, failing that, a way to make linking not break in some other clever way?

• Matlab crashes on library initialize when called from Java

  - by David Sauter

  Hello everyone. The setup I have is I'm using a Java application to call native C-code with JNI, which in turn starts up the MATLAB runtime and calls functions on it (I know there are other solutions to call MATLAB methods from Java). The problem is that the MATLAB engine crashes at some point during the initialization and I don't know what's causing it exactly. The crash causes my jvm to terminate, I assume it's some kind of memory corruption. The C++ code calling MATLAB functions that is actually crashing is JNIEXPORT void JNICALL some_jni_vodoo_initializeLibrary(JNIEnv* env, jclass thisClass) { try { if (!mclInitializeApplication(NULL, 0)) { THROW_EXCEPTION(env, "Could not initialize the application properly."); return; } if (!<library>Initialize()) { THROW_EXCEPTION(env, "Could not initialize the library."); return; } } ... The function <library>Initialize() crashes here, the Java error log reads Stack Trace: [0] jmi.dll:0x793f4175(0x7934cdca, 1, 0x7937e67c "à;.y`[email protected] in C:\BUILD_ARE..", 0x792d6a32) [1] jvm.dll:0x792df9a5(0xc0000005, 0x79356791, 0x4961b400 "Ð\8y", 0x6d8b29de) [2] jvm.dll:0x792e0431(0x8b515008, 0x70f0e8ce, 0x8b5ffffa, 0xc25d5ec6) ------------------------------------------------------------------------ Fatal Java Exception detected at Fri Apr 30 11:08:08 2010 ------------------------------------------------------------------------ Configuration: MATLAB Version: 7.8.0.347 (R2009a) MATLAB License: unknown Operating System: Microsoft Windows Vista Window System: Version 6.0 (Build 6002: Service Pack 2) Processor ID: x86 Family 6 Model 10 Stepping 5, GenuineIntel Virtual Machine: Java is not enabled Default Encoding: windows-1252 Java is not enabled I really have no idea what could be wrong. Is there not enough memory from the jvm? I guess the problem is somehow related to Java, since calling the JNI functions from a simple test C++ program works fine... Thanks

• How to test an HTTP 301 redirect?

  - by NoozNooz42

  How can one easily test HTTP return codes, like, say, a 301 redirect? For example, if I want to "see what's going on", I can use telnet to do something like this: ... $ telnet nytimes.com 80 Trying 199.239.136.200... Connected to nytimes.com. Escape character is '^]'. GET / HTTP/1.0 (enter) (enter) HTTP/1.1 200 OK Server: Sun-ONE-Web-Server/6.1 Date: Mon, 14 Jun 2010 12:18:04 GMT Content-type: text/html Set-cookie: RMID=007af83f42dd4c161dfcce7d; expires=Tuesday, 14-Jun-2011 12:18:04 GMT; path=/; domain=.nytimes.com Set-cookie: adxcs=-; path=/; domain=.nytimes.com Set-cookie: adxcs=-; path=/; domain=.nytimes.com Set-cookie: adxcs=-; path=/; domain=.nytimes.com Expires: Thu, 01 Dec 1994 16:00:00 GMT Cache-control: no-cache Pragma: no-cache Connection: close <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> ... Which is an easy way to access quite some infos. But now I want to test that a 301 redirect is indeed a 301 redirect. How can I do so? Basically, instead of getting a HTTP/1.1 200 OK I'd like to know how I can get the 301? I know that I can enter the name of the URL in a browser and "see" that I'm redirected, but I'd like to know what tool(s) can be used to actually really "see" the 301 redirect. Btw, I did test with a telnet, but when I enter www.example.org, which I redirected to example.org (without the www), all I can see is an "200 OK", I don't get to see the 301.

• What are the benefits of running chef-server instead of chef-solo?

  - by strife25

  I am looking at automated deployment solutions for my team and have been playing with Chef for the past few days. I've been able to get a simple web app up an running from a base Red Hat VM using chef-solo. Our end goal is to use Chef (or another system) to automatically deploy application topologies to the cloud as we run builds. Our process would basically run like so: Our web app code, dependencies, and chef cookbooks are stored in SCM A build is executed and greats a single package for images to acquire and test against The build engine then deploys new cloud images that run a chef client to get packages installed. The images acquire the cookbooks from SCM or the Chef server and install everything to get up and running What are the benefits and/or use cases for getting a Chef Server running? Are there any major benefits to have a Chef Server hold and acquire the cookbooks from SCM vs. using chef-solo and having a script that will pull the cookbooks from SCM?

• Jetty startup delay

  - by Tauren

  I'm trying to figure out what would be causing a 1 minute delay in the startup of Jetty. Is it a configuration problem, my application, or something else? I have Jetty 7 (jetty-7.0.1.v20091125 25 November 2009) installed on a server and I deploy a 45MB ROOT.war file into the webapps directory. This is the only webapp configured in Jetty. I then start Jetty with the command: java -DSTOP.PORT=8079 -DSTOP.KEY=mystopkey -Denv=stage -jar start.jar etc/jetty-logging.xml etc/jetty.xml & I get two lines of output right after doing this: 2010-03-07 14:20:06.642:INFO::Logging to StdErrLog::DEBUG=false via org.eclipse.jetty.util.log.StdErrLog 2010-03-07 14:20:06.710:INFO::Redirecting stderr/stdout to /home/zing/jetty-distribution-7.0.1.v20091125/logs/2010_03_07.stderrout.log When I press the enter key, I get my command prompt back. Looking at the log file (logs/2010_03_07.stderrout.log), I see the following at the beginning: 2010-03-07 14:08:50.396:INFO::jetty-7.0.1.v20091125 2010-03-07 14:08:50.495:INFO::Extract jar:file:/home/zing/jetty-distribution-7.0.1.v20091125/webapps/ROOT.war!/ to /tmp/Jetty_0_0_0_0_8080_ROOT.war___.8te0nm/webapp 2010-03-07 14:08:52.599:INFO::NO JSP Support for , did not find org.apache.jasper.servlet.JspServlet 2010-03-07 14:09:51.379:INFO::Set web app root system property: 'webapp.root' = [/tmp/Jetty_0_0_0_0_8080_ROOT.war___.8te0nm/webapp] 2010-03-07 14:09:51.585:INFO::Initializing Spring root WebApplicationContext INFO - ContextLoader - Root WebApplicationContext: initialization started INFO - XmlWebApplicationContext - Refreshing Root WebApplicationContext: startup date [Sun Mar 07 14:09:51 PST 2010]; root of context hierarchy ...

It doesn't even look like it has started my Spring initialization yet. Note that I checked my /tmp directory to see if it was simply the time to unpack my war file, but the file had been completely unpacked even at the start of this 1 minute delay.

• Java Server Client Program I/O Exception

  - by AjayP

  I made this program: http://java.sun.com/docs/books/tutorial/networking/sockets/clientServer.html And it works perfectly if I put the server's hostname as 127.0.0.1 or my computers name (Ajay-PC). However these 2 methods are LAN or local only not internet. So I changed it to my internet ip. 70.128.xxx.xxx etc. But it didn't work. I checked: canyouseeme.org and it said 4444 was CLOSED. So I did a quick port forward. Portforward: Name: My Java Program Start Port: 4444 End Port: 4444 Server IP: 10.0.0.12 <-- (Yeah this is my Local IP I checked) then I tried canyouseeme.org AGAIN: and it said 4444 was OPEN I ran my server client program and it yet to work. So my problem is the client server program is not working on the internet just locally. So something is blocking it and I don't know what. Computer: Windows Vista x64 Norton AntiVirus 2010 Thanks! I'll give best answer or whatever to who ever answers the best ;) :)

• String trouble in Rave Reports 8

  - by Jørn E. Angeltveit

  We are currently working with Delphi 2006, but we are now very ready to move on to Delphi 2010. The problem lies in our Rave reports, though... We just get to many string errors when running our reports with Rave 8. And they just don't make any sense. (The reports compile with no error, and we can even run them without any error in Rave 6.) For instance: //This event causes access violation (in rtl14.bpl) at run time { Event for Page1.OnBeforeReport } function Page1_OnBeforeReport(Self: TRavePage); var s: String; begin s := 'My text in param'; s := s + ' and som more text'; s := copy(s,1,length(s)) + ' and then some more'; RaveProject.SetParam('MyTestParam', s); end OnBeforeReport; //This event works OK { Event for Page1.OnBeforeReport } function Page1_OnBeforeReport(Self: TRavePage); var s: String; begin s := 'My text in param'; s := s + ' and som more text'; s := copy(s,1,length(s)); // + ' and then some more'; RaveProject.SetParam('MyTestParam', s); end OnBeforeReport; //This event works OK too { Event for Page1.OnBeforeReport } function Page1_OnBeforeReport(Self: TRavePage); var s: String; begin s := 'My text in param'; s := s + ' and som more text'; s := copy(s,1,length(s)) + s; RaveProject.SetParam('MyTestParam', s); end OnBeforeReport; We really want to stick to Rave, because we have a lot of reports (150+) with a lot of functionality (sql statements, events etc). Besides, we have customers who have designed their own custom reports as well. Does anybody know the reason for these errors? Is there any solution or workaround to these problems?

• How do you Access an Authenticated Google App Engine Service with Ruby?

  - by viatropos

  I am trying to do this same thing here but with Ruby: Access Authenticated GAE Client with Python. Any ideas how to retrieve authenticated content from GAE with Ruby? I am using the Ruby GData Gem to access everything in Google Docs and such and it's making life very easy, but now I'd like to access things on GAE that require admin access, programmatically, and it doesn't support that. Here's what I'm getting (using DocList, not sure what to use yet): c = GData::Client::DocList.new c.clientlogin(username, password, nil, nil, nil, "HOSTED") c => #<GData::Client::DocList:0x201bad8 @clientlogin_service="writely", @version="2", @auth_handler=#<GData::Auth::ClientLogin:0x200803c @account_type="HOSTED", @token="long-hash", @auth_url="https://www.google.com/accounts/ClientLogin", @service="writely">, @source="AnonymousApp", @headers={"Authorization"=>"GoogleLogin auth=long-hash", "User-Agent"=>"GoogleDataRubyUtil-AnonymousApp", "GData-Version"=>"2", "Content-Type"=>"application/atom+xml"}, @authsub_scope="http://docs.google.com/feeds/", @http_service=GData::HTTP::DefaultService> url = "http://my-cdn.appspot.com/files/restricted-file.html" c.get(url) => #<GData::HTTP::Response:0x20004b8 @status_code=302, @body="", @headers={"connection"=>"close", "date"=>"Sun, 11 Apr 2010 00:30:20 GMT", "content-type"=>"text/html", "server"=>"Google Frontend", "content-length"=>"0", "location"=>"https://www.google.com/accounts/ServiceLogin service=ah&continue=http://my-cdn.appspot.com/_ah/login%3Fcontinue%3D http://my-cdn.appspot.com/files/restricted-file.html& ltmpl=gm&ahname=My+CDN&sig=a-signature"}> Any tips? That other SO question pointed to doing something with the redirect... Not sure how to handle that. Just looking for a point in the right direction from the ruby experts. Thanks.

• android compile error: could not reserve enough space for object heap

  - by moonlightcheese

  I'm getting this error during compilation: Error occurred during initialization of VM Could not create the Java virtual machine. Could not reserve enough space for object heap What's worse, the error occurs intermittently. Sometimes it happens, sometimes it doesn't. It seems to be dependent on the amount of code in the application. If I get rid of some variables or drop some imported libraries, it will compile. Then when I add more to it, I get the error again. I've included the following sources into the application in the [project_root]/src/ directory: org.apache.httpclient (I've stripped all references to log4j from the sources, so don't need it) org.apache.codec (as a dependency) org.apache.httpcore (dependency of httpclient) and my own activity code consisting of nothing more than an instance of HttpClient. I know this has something to do with the amount of memory necessary during compile time or some compiler options, and I'm not really stressing my system while i'm coding. I've got 2GB of memory on this Core Duo laptop and windows reports only 860MB page file usage (haven't used any other memory tools. I should have plenty of memory and processing power for this... and I'm only compiling some common http libs... total of 406 source files. What gives? edit (4/30/2010-18:24): Just compiled some code where I got the above stated error. I closed some web browser windows and recompiled the same exact code with no edits and it compiled with no issue. this is definitely a compiler issue related to memory usage. Any help would be great.... because I have no idea where to go from here. Android API Level: 5 Android SDK rel 5 JDK version: 1.6.0_12 Sorry I had to repost this question because regardless of whether I use the native HttpClient class in the Android SDK or my custom version downloaded from apache, the error still occurs.

• Stored proc running 30% slower through Java versus running directly on database

  - by James B

  Hi All, I'm using Java 1.6, JTDS 1.2.2 (also just tried 1.2.4 to no avail) and SQL Server 2005 to create a CallableStatement to run a stored procedure (with no parameters). I am seeing the Java wrapper running the same stored procedure 30% slower than using SQL Server Management Studio. I've run the MS SQL profiler and there is little difference in I/O between the two processes, so I don't think it's related to query plan caching. The stored proc takes no arguments and returns no data. It uses a server-side cursor to calculate the values that are needed to populate a table. I can't see how the calling a stored proc from Java should add a 30% overhead, surely it's just a pipe to the database that SQL is sent down and then the database executes it....Could the database be giving the Java app a different query plan?? I've posted to both the MSDN forums, and the sourceforge JTDS forums (topic: "stored proc slower in JTDS than direct in DB") I was wondering if anyone has any suggestions as to why this might be happening? Thanks in advance, -James (N.B. Fear not, I will collate any answers I get in other forums together here once I find the solution) Java code snippet: sLogger.info("Preparing call..."); stmt = mCon.prepareCall("SP_WB200_POPULATE_TABLE_limited_rows"); sLogger.info("Call prepared. Executing procedure..."); stmt.executeQuery(); sLogger.info("Procedure complete."); I have run sql profiler, and found the following: Java app : CPU: 466,514 Reads: 142,478,387 Writes: 284,078 Duration: 983,796 SSMS : CPU: 466,973 Reads: 142,440,401 Writes: 280,244 Duration: 769,851 (Both with DBCC DROPCLEANBUFFERS run prior to profiling, and both produce the correct number of rows) So my conclusion is that they both execute the same reads and writes, it's just that the way they are doing it is different, what do you guys think? It turns out that the query plans are significantly different for the different clients (the Java client is updating an index during an insert that isn't in the faster SQL client, also, the way it is executing joins is different (nested loops Vs. gather streams, nested loops Vs index scans, argh!)). Quite why this is, I don't know yet (I'll re-post when I do get to the bottom of it) Epilogue I couldn't get this to work properly. I tried homogenising the connection properties (arithabort, ansi_nulls etc) between the Java and Mgmt studio clients. It ended up the two different clients had very similar query/execution plans (but still with different actual plan_ids). I posted a summary of what I found to the MSDN SQL Server forums as I found differing performance not just between a JDBC client and management studio, but also between Microsoft's own command line client, SQLCMD, I also checked some more radical things like network traffic too, or wrapping the stored proc inside another stored proc, just for grins. I have a feeling the problem lies somewhere in the way the cursor was being executed, and it was somehow giving rise to the Java process being suspended, but why a different client should give rise to this different locking/waiting behaviour when nothing else is running and the same execution plan is in operation is a little beyond my skills (I'm no DBA!). As a result, I have decided that 4 days is enough of anyone's time to waste on something like this, so I will grudgingly code around it (if I'm honest, the stored procedure needed re-coding to be more incremental instead of re-calculating all data each week anyway), and chalk this one down to experience. I'll leave the question open, big thanks to everyone who put their hat in the ring, it was all useful, and if anyone comes up with anything further, I'd love to hear some more options...and if anyone finds this post as a result of seeing this behaviour in their own environments, then hopefully there's some pointers here that you can try yourself, and hope fully see further than we did. I'm ready for my weekend now! -James

• Advanced file compression software for Mac OSX

  - by Steven Roose

  Back when I used Windows, I always used WinRAR for file compression and decompression. It had a fair amount of options like 'just storage' vs 'hard compression', password protection and archive type. Now that I use Mac OSX, the only compression possibility I have is the default Finder's Compress to Zip. I downloaded the most popular decompression software "Unarchiver". But this app can't compress other archive types either. I went for a search but there seem to be hardly any good advanced compression tools that work nice in OSX and have the options WinRAR has. (WinRAR works in OSX but command line only, I'm looking for something with a GUI.) Any ideas? I strongly prefer freeware. I found Archiver and StiffIt, but they are both commercial.

• Will fixed-point arithmetic be worth my trouble?

  - by Thomas

  I'm working on a fluid dynamics Navier-Stokes solver that should run in real time. Hence, performance is important. Right now, I'm looking at a number of tight loops that each account for a significant fraction of the execution time: there is no single bottleneck. Most of these loops do some floating-point arithmetic, but there's a lot of branching in between. The floating-point operations are mostly limited to additions, subtractions, multiplications, divisions and comparisons. All this is done using 32-bit floats. My target platform is x86 with at least SSE1 instructions. (I've verified in the assembler output that the compiler indeed generates SSE instructions.) Most of the floating-point values that I'm working with have a reasonably small upper bound, and precision for near-zero values isn't very important. So the thought occurred to me: maybe switching to fixed-point arithmetic could speed things up? I know the only way to be really sure is to measure it, that might take days, so I'd like to know the odds of success beforehand. Fixed-point was all the rage back in the days of Doom, but I'm not sure where it stands anno 2010. Considering how much silicon is nowadays pumped into floating-point performance, is there a chance that fixed-point arithmetic will still give me a significant speed boost? Does anyone have any real-world experience that may apply to my situation?

• Authenticating Linux users against AD without Likewise Open

  - by Graeme Donaldson

  Has anyone got their Linux systems authenticating against Active Directory without using Likewise Open? We are close to implementing Likewise Open, but first we need to rename roughly 70 of 110 Linux servers so that their hostnames are not longer than 15 characters. This is required because Likewise Open actually joins the Linux computer to the domain, and it fails to do so if the hostname is too long due to some legacy NetBIOS naming limitation. Is there a way to authenticate via AD, using only LDAP perhaps? What are the advantages/disadvantages over doing it like that vs just using Likewise?
