  • PrintableArea in C# - Bug?

    - by Brandi
    I am having an issue with PageSettings.PrintableArea's width and height values. Width, Height, and Size properties claim to "get or set" the values. Also, the inflate() function claims to change the size based on values passed in. However, all of these attempts to change the value have not worked. Inflate() is ignore (no error, just passes as if it worked, but the values remain unchanged. Attempting to set the height, width, or size gives a compiler error: "Cannot modify the return value of 'System.Drawing.Printing.PageSettings.PrintableArea' because it is not a variable". I get the feeling that this means the "or set" part of the description is a lie. Why I want to know this: (Someone always asks...) I have a printing application (C#, WinForm) that for most things is working rather well. I can set the printer settings and page settings objects to control what displays in the print dialog's printer properties. However, with Microsoft Office Document Image Writer, these settings are sometimes ignored, and the paper size returns as 0, 0 even when it displayed something else. All I really want it for it to be WYSIWYG as far as the displayed values go, so I change the paper size back to what it should be, but the printable area, if it is wrong, makes the resulting image wonky. The resulting image is the size of the printable area instead of the value in papersize. Just wondering if there was a reason for this or a way to get it not to do that. Thanks in advance. :)

  • Preserving Language across inline Calculated Members in SSAS

    - by Tullo
    Problem: I need to retrieve the language of a given cell from the cube. The cell is defined by code-generated MDX, which can have an arbitrary level of indirection as far as calculated members and sets go (defined in the WITH clause). SSAS appears to ignore the Language of the specified members when you declare a calculated member inline in the query. Example: The cube's default locale is 1033 (en-US) The cube contains a Calculated Measure called [Net Pounds] which is defined as [Net Amt], language=2057 (en-GB) The query requests this measure alongside an inline calculated measure which is simply an alias to the [Net Pounds] When used directly, the measure is formatted in the en-GB locale, but when aliased, the measure falls back to using the cube default of en-US. Here's what the query looks like: WITH MEMBER [Measures].[Pounds Indirect] AS [Measures].[Net Pounds] SELECT { [Measures].[Pounds Indirect], [Measures].[Net Pounds] } ON AXIS (0) FROM [Cube] CELL PROPERTIES language, value, formatted_value The query returns the expected two cells, but only uses the [Net Pounds] locale when used directly. Is there an option or switch somewhere in SSAS that will allow locale information to be visible in calculated members? I realise that it is possible to declare the inline calculated member in a particular locale, but this would involve extracting the locale from the tuple first, which (since the cube's member is isolated in the application's query schema) is unknown.

  • How to manage Javascript modules in django templates?

    - by John Mee
    Lets say we want a library of javascript-based pieces of functionality (I'm thinking jquery): For example: an ajax dialog a date picker a form validator a sliding menu bar an accordian thingy There are four pieces of code for each: some Python, CSS, JS, & HTML. What is the best way to arrange all these pieces so that: each javascript 'module' can be neatly reused by different views the four bits of code that make up the completed function stay together the css/js/html parts appear in their correct places in the response common dependencies between modules are not repeated (eg: a javascript file in common) x-------------- It would be nice if, or is there some way to ensure that, when called from a templatetag, the templates respected the {% block %} directives. Thus one could create a single template with a block each for CSS, HTML, and JS, in a single file. Invoke that via a templatetag which is called from the template of whichever view wants it. That make any sense. Can that be done some way already? My templatetag templates seem to ignore the {% block %} directives. x-------------- There's some very relevant gasbagging about putting such media in forms here http://docs.djangoproject.com/en/dev/topics/forms/media/ which probably apply to the form validator and date picker examples.

  • Issue with VS 2008 designer and usercontrol.

    - by Ram
    Hello, I have created a custom data grid control. I dragged it on windows form and set its properties like column and all & ran the project. It built successfully and I am able to view the grid control on the form. Now if i try to view that form in designer, I am getting following error.. Object reference not set to an instance of an object. Instances of this error (1) 1.

However I can see the code for the grid in the designer file. Any pointer on this would be a great help.

  • Reinforcement learning toy project

    - by Betamoo
    My toy project to learn & apply Reinforcement Learning is: - An agent tries to reach a goal state "safely" & "quickly".... - But there are projectiles and rockets that are launched upon the agent in the way. - The agent can determine rockets position -with some noise- only if they are "near" - The agent then must learn to avoid crashing into these rockets.. - The agent has -rechargable with time- fuel which is consumed in agent motion - Continuous Actions: Accelerating forward - Turning with angle I need some hints and names of RL algorithms that suit that case.. - I think it is POMDP , but can I model it as MDP and just ignore noise? - In case POMDP, What is the recommended way for evaluating probability? - Which is better to use in this case: Value functions or Policy Iterations? - Can I use NN to model environment dynamics instead of using explicit equations? - If yes, Is there a specific type/model of NN to be recommended? - I think Actions must be discretized, right? I know it will take time and effort to learn such a topic, but I am eager to.. You may answer some of the questions if you can not answer all... Thanks

  • How to insert a blank line above my copyright text inside the comment lines in intelliJ IDEA?

    - by tim_wonil
    I'm using intelliJ IDEA 9. It has a function to make a copyright profile and apply to all files I create. What I'm trying to do is to format the copyright comment right. Suppose I have a copyright text as this: Copyright (c) 2010 my.company. All rights reserved. I wish it to be inserted in files automatically as following: //////////////////////////////////////////////////////////////////////////////// // // Copyright (c) 2010 my.company. All rights reserved. // //////////////////////////////////////////////////////////////////////////////// But when I enter the line "Copyright (c) 2010 my.company. All rights reserved." in the copyright profile (without quotes) and configure the formatting to use line comment and borders, and so on, I can only make it to display as below: //////////////////////////////////////////////////////////////////////////////// // Copyright (c) 2010 my.company. All rights reserved. //////////////////////////////////////////////////////////////////////////////// Even when I put the copyright text with blank line above and below to the template, as following, it still comes out like above. Copyright (c) 2010 my.company. All rights reserved. It seems to ignore blank lines in the copyright template. Is there any way to configure it so the copyright text will have blank lines above and below within the comments?

  • Confusion about maven-war-plugin and jetty-maven-plugin

    - by waxwing
    I am trying to get the run-exploded goal of the jetty-maven-plugin to work correctly. I find the documentation somewhat lacking on what I need to do to set this up. I believe I have a standard WAR-file setup. (The reason I wrote "believe" is that I find the maven-war-plugin documentation lacking as well.) When I build my webapp using maven package, I get the following in my target folder: classes maven-archiver surefire-reports test-classes tmp mywebapp-version mywebapp-version.war where mywebapp-version is the exploded war and mywebapp-version.war is the packaged one. So far so good (I think?). Now, running mvn jetty:run-exploded, it seems the default deploy folder is target/tmp/webapp/mywebapp-version.war/. This folder exists, but contains no files except for a webapp-cache.xml. This seems wrong to me. I also tried to actively set the webApp configuration element to ${project.build.directory}/mywebapp-version/, but run-exploded seems to ignore it (despite the documentation stating otherwise). What am I doing wrong? It looks as if I am missing something simple since no one else appears to be running into the same problem.

  • FxCop hates my usage of MVVM

    - by Dave
    I've just started to work with FxCop to see how poorly my code does against its full set of rules. I'm starting off with the "Breaking" rules, and the first one I came across was CA2227, which basically says that you should make a collection property's setter readonly, so that you can't accidentally change the collection data. Since I'm using MVVM, I've found it very convenient to use an ObservableCollection with get/set properties because it makes my GUI updates easy and concise in the code-behind. However, I can also see what FxCop is complaining about. Another situation that I just ran into is with WF, where I need to set the parameters when creating the workflow, and I'd hate to have to write a wrapper class around the collection I'm using just to avoid this particular error message. For example, here's a sample runtime error message that I get when I make properties readonly: The activity 'MyWorkflow' has no public writable property named 'MyCollectionOfStuff' What are you opinions on this? I could either ignore this particular error, but that's probably not good because I could conceivably violate this rule elsewhere in the code where MVVM doesn't apply (model only code, for example). I think I could also change it from a property to a class with methods to manipulate the underlying collection, and then raise the necessary notification from the setter method. I'm a little confused... can anyone shed some light on this?

  • MKMapView loading all annotation views at once (including those that are outside the current rect)

    - by jmans
    Has anyone else run into this problem? Here's the code: - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(WWMapAnnotation *)annotation { // Only return an Annotation view for the placemarks. Ignore for the current location--the iPhone SDK will place a blue ball there. NSLog(@"Request for annotation view"); if ([annotation isKindOfClass:[WWMapAnnotation class]]){ MKPinAnnotationView *browse_map_annot_view = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"BrowseMapAnnot"]; if (!browse_map_annot_view) { browse_map_annot_view = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"BrowseMapAnnot"] autorelease]; NSLog(@"Creating new annotation view"); } else { NSLog(@"Recycling annotation view"); browse_map_annot_view.annotation = annotation; } ... As soon as the view is displayed, I get 2009-08-05 13:12:03.332 xxx[24308:20b] Request for annotation view 2009-08-05 13:12:03.333 xxx[24308:20b] Creating new annotation view 2009-08-05 13:12:03.333 xxx[24308:20b] Request for annotation view 2009-08-05 13:12:03.333 xxx[24308:20b] Creating new annotation view and on and on, for every annotation (~60) I've added. The map (correctly) only displays the two annotations in the current rect. I am setting the region in viewDidLoad: if (center_point.latitude == 0) { center_point.latitude = 35.785098; center_point.longitude = -78.669899; } if (map_span.latitudeDelta == 0) { map_span.latitudeDelta = .001; map_span.longitudeDelta = .001; } map_region.center = center_point; map_region.span = map_span; NSLog(@"Setting initial map center and region"); [browse_map_view setRegion:map_region animated:NO]; The log entry for the region being set is printed to the console before any annotation views are requested. The problem here is that since all of the annotations are being requested at once, [mapView dequeueReusableAnnotationViewWithIdentifier] does nothing, since there are unique MKAnnotationViews for every annotation on the map. This is leading to memory problems for me. One possible issue is that these annotations are clustered in a pretty small space (~1 mile radius). Although the map is zoomed in pretty tight in viewDidLoad (latitude and longitude delta .001), it still loads all of the annotation views at once. Thanks...

  • C# - closures over class fields inside an initializer?

    - by Richard Berg
    Consider the following code: using System; namespace ConsoleApplication2 { class Program { static void Main(string[] args) { var square = new Square(4); Console.WriteLine(square.Calculate()); } } class MathOp { protected MathOp(Func<int> calc) { _calc = calc; } public int Calculate() { return _calc(); } private Func<int> _calc; } class Square : MathOp { public Square(int operand) : base(() => _operand * _operand) // runtime exception { _operand = operand; } private int _operand; } } (ignore the class design; I'm not actually writing a calculator! this code merely represents a minimal repro for a much bigger problem that took awhile to narrow down) I would expect it to either: print "16", OR throw a compile time error if closing over a member field is not allowed in this scenario Instead I get a nonsensical exception thrown at the indicated line. On the 3.0 CLR it's a NullReferenceException; on the Silverlight CLR it's the infamous Operation could destabilize the runtime.

  • Problems compiling peazip on OSX

    - by Yansky
    I'm having some problems with compiling Peazip on OSX (10.6). I emailed the Peazip developer and he said he probably couldn't help me too much as the error seems to be OSX specific and he doesn't have access to an OSX machine any more. The compiler I'm using is Lazarus as the source is in Pascal. The actual compile process seems to go ok, but when I run the peazip.app program launcher, I get the following error: http://img.photobucket.com/albums/v215/thegooddale/Screen-shot-2010-05-22-at-71907-PM.png Here is the app launcher that the compile made: http://forboden.com/coding/peazip.app.zip - you can use an unzip program to look at the files inside (i.e. unzip it twice). I also tried just running the peazip unix file executable that was produced after the compile from the terminal and I got this: http://img.photobucket.com/albums/v215/thegooddale/Screen-shot-2010-05-22-at-72148-PM.png Here are the messages from the compile log from Lazarus while compiling Peazip: http://pastebin.com/qK4bdncL (I asked on the Lazarus forums and they said I can just ignore those "ld: warning: unknown stabs type" warnings). Here is the info from the project_peach.compiled file: <?xml version="1.0"?> <CONFIG> <Compiler Value="/usr/local/bin/ppc386" Date="1238949773"/> <Params Value=" -MObjFPC -Sgi -O1 -gl -k-framework -kCarbon -k-framework -kOpenGL -k'-dylib_file' -k'/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib' -WG -vewnhi -l -Fu/Users/yansky/Desktop/peazip-3.1.src/res/themes/crystalc/ -Fu/Developer/lazarus/components/synedit/units/i386-darwin/ -Fu/Developer/lazarus/ideintf/units/i386-darwin/ -Fu/Developer/lazarus/lcl/units/i386-darwin/ -Fu/Developer/lazarus/lcl/units/i386-darwin/carbon/ -Fu/Developer/lazarus/packager/units/i386-darwin/ -Fu/Users/yansky/Desktop/peazip-3.1.src/ -Fu. -opeazip -dLCL -dLCLcarbon project_peach.lpr"/> </CONFIG> I guess there's little chance that anyone here has experience with Pascal and Lazarus since it's not that popular a language and the compiler is still in beta, but I thought I would post here in the hopes that someone might point me in the right general direction about where/how the peazip.app launcher is breaking.

  • How to implement a .net 3-tier architecture using Winforms

    - by Anders Jakobsen
    I have for some time build n-tier Applications using a database server as the data tier, Winforms as the presentation tier and an ASP.NET asmx webservice in the middle to send back and forth untyped Datasets. While this approach has worked for me so far, it certainly does feel outdated today. What technologies should I use if I were to create a similar architectured application today? .net 4.0 technology is welcome. I still want a database server as the datatier and the asmx webservices should probably be replaced by WCF. I would still like to have the presentation tier running as a desktop application (Winforms or WPF) so ignore ASP.net for this question. My main question really comes down to what to use as business objects. I want something that is easier to bind to the interface than untyped Datasets and strongly-typed datasets feels very heavy. I also need something that can track changes to make sure users do not override each other's changes in the database. Will the Entity Framework 4 be usable for a scenario like this? Are there any thorough guides available?

  • Handling Digital ID/Signature in Outlook Add-in

    - by CoSteve
    I have a C# Outlook Add-In application (VS2005 and 2003 Outlook) that reads incoming emails and strips out the attachments and the email text body for future processing. Occasionally I'll get an email that contains a digital signature. The application will fail when I try to access the mailitem.body property, throwing the following exception: System.Runtime.InteropServices.COMException (0xAB404001): The operation failed. at Microsoft.Office.Interop.Outlook._MailItem.get_Body() at MyLib.MyApp.OutlookAddin.MailProcessor.ProcessMailItem(MailItem mailItem) I'm pretty sure it is the digital signature causing the problem because if I forward the email back to myself, it will strip off the original sender's digital signature and the add-in application will process the email without any problems. I'm not sure what to do. I need to process the email, so I can't just ignore it. Somehow getting the body of the original email without throwing an exception would be ideal. Or I guess if I can identify that there is a digital signature associated with the email, I could forward the email to myself, but that seems a little messy. Does anyone have any suggestions/fixes? Thanks for any help.

  • Prevent full table scan for query with multiple where clauses

    - by Dave Jarvis
    A while ago I posted a message about optimizing a query in MySQL. I have since ported the data and query to PostgreSQL, but now PostgreSQL has the same problem. The solution in MySQL was to force the optimizer to not optimize using STRAIGHT_JOIN. PostgreSQL offers no such option. Here is the explain: Here is the query: SELECT avg(d.amount) AS amount, y.year FROM station s, station_district sd, year_ref y, month_ref m, daily d LEFT JOIN city c ON c.id = 10663 WHERE -- Find all the stations within a specific unit radius ... -- 6371.009 * SQRT( POW(RADIANS(c.latitude_decimal - s.latitude_decimal), 2) + (COS(RADIANS(c.latitude_decimal + s.latitude_decimal) / 2) * POW(RADIANS(c.longitude_decimal - s.longitude_decimal), 2)) ) <= 50 AND -- Ignore stations outside the given elevations -- s.elevation BETWEEN 0 AND 2000 AND sd.id = s.station_district_id AND -- Gather all known years for that station ... -- y.station_district_id = sd.id AND -- The data before 1900 is shaky; insufficient after 2009. -- y.year BETWEEN 1980 AND 2000 AND -- Filtered by all known months ... -- m.year_ref_id = y.id AND m.month = 12 AND -- Whittled down by category ... -- m.category_id = '001' AND -- Into the valid daily climate data. -- m.id = d.month_ref_id AND d.daily_flag_id <> 'M' GROUP BY y.year It appears as though PostgreSQL is looking at the DAILY table first, which is simply not the right way to go about this query as there are nearly 300 million rows. How do I force PostgreSQL to start at the CITY table? Thank you!

  • Load testing multipart form

    - by JacobM
    I'm trying to load-test a Rails application using JMeter. A critical part of the application involves a form that includes both text inputs and file uploads. It works fine in a browser, but when I try to post that page in JMeter, Rails is saving all of the parts of the multipart form as temp files, which causes things to break when it's looking for a string and gets a tempfile instead. It appears that the difference is that, from a browser, the piece of the multipart request that contains a text input looks like this: -----------------------------7d93b4186074c Content-Disposition: form-data; name="field_name" test -----------------------------7d93b4186074c while from JMeter it looks like this: -----------------------------7d159c1302d0y0 Content-Disposition: form-data; name="field_name" Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit test -----------------------------7d159c1302d0y0 So apparently Rails sees the former and interprets it as a plain text value and treats it as a string, but sees the latter and saves it to a temp file. I have not been able to find a setting to convince JMeter not to send the additional headers in the multipart form for non-file fields. Is there a way to convince Rails to ignore those headers and treat the text/plain text as strings instead of text files? Or a quick way to put a filter in front of my controller that will strip the extra headers? Alternately, is there a better tool to load-test a Rails application that includes file upload?

  • Wix create non advertised shortcut for all users / per machine

    - by mcdon
    In WIX, how do you create a non advertised shortcut in the allusers profile? So far I've only been able to accomplish this with advertised shortcuts. I prefer advertised shortcuts because you can go to the shortcut's properties and use "find target". In the tutorials I've seen use a registry value for the keypath of a shortcut. The problem is they use HKCU as the root. When HKCU is used, and another user uninstalls the program (since it's installed for all users) the registry key is left behind. When I use HKMU as the root I get an ICE57 error, but the key is removed when another user uninstalls the program. I seem to be pushed towards using HKCU though HKMU seems to behave correctly (per-user vs all-users). When I try to create the non advertised shortcut I get various ICE error such as ICE38, ICE43, or ICE 57. Most articles I've seen recommend "just ignore the ice errors". There must be a way to create the non advertised shortcuts, without creating ICE errors. Please post sample code for a working example.

  • Clear form field after select for jQuery UI Autocomplete

    - by jonfhancock
    I'm developing a form, and using jQuery UI Autocomplete. When the user selects an option, I want the selection to pop into a span appended to the parent <p> tag. Then I want the field to clear rather than be populated with the selection. I have the span appearing just fine, but I can't get the field to clear. How do you cancel jQuery UI Autocomplete's default select action? Here is my code: var availableTags = ["cheese", "milk", "dairy", "meat", "vegetables", "fruit", "grains"]; $("[id^=item-tag-]").autocomplete({ source: availableTags, select: function(){ var newTag = $(this).val(); $(this).val(""); $(this).parent().append("<span>" + newTag + "<a href=\"#\">[x]</a> </span>"); } }); Simply doing $(this).val(""); doesn't work. What is maddening is that almost the exact function works fine if I ignore autocomplete, and just take action when the user types a comma as such: $('[id^=item-tag-]').keyup(function(e) { if(e.keyCode == 188) { var newTag = $(this).val().slice(0,-1); $(this).val(''); $(this).parent().append("<span>" + newTag + "<a href=\"#\">[x]</a> </span>"); } }); The real end result is to get autocomplete to work with multiple selections. If anybody has any suggestions for that, they would be welcome.

  • Web service SSL handshake fails in production environment unless SSL debugging enabled

    - by JST
    Scenario: calling a client web service over SSL (https) with mutual SSL authentication. Different service endpoint URLs and certs (both keystore and truststore) for test vs. production environments. Both test and production environments run tomcat / JBoss clustered. Production environment has load balancing / BigIP, runs Blade and non-Blade machines. Truststore is set (using -Djavax.net.ssl.trustStore=value) at startup. Keystore is set using System.setProperty("javax.net.ssl.keyStore", "value") in Java code. Web service call made using Axis2. All works fine in test environment, but when we moved to production environment (6 servers), it appears certs are not being forwarded for the handshake. Here's what we've done: in test environment, handshake using test versions of certs has been working all along, with no ssl debugging enabled confirmed in test environment that handshake with client production endpoint succeeds (production certs, both ours and theirs, are fine) -- this was done using -Djavax.net.debug=handshake,ssl confirmed that the error condition occurs on all 6 production servers took one server out of the cluster, turned on ssl debugging for just that one (with a restart), hit it directly, handshake works! switched to a different server without the debugging turned on, handshake error condition occurs turned debugging on on that second server (with a restart), hit it directly, handshake works! From the evidence, it seems like somehow the debugging being enabled causes the certificates to be properly retrieved/conveyed, although that makes no sense! I wonder whether somehow the enabled debugging makes the system pay attention to the System.setProperty call, and ignore it otherwise. However, in local and test environments, handshake worked without debugging enabled. Do I maybe need to be setting keystore on server startup like I'm setting truststore? Have been avoiding that because the keystore will differ for each of our test environments (16 of them).

  • AutoMapper How To Map Object A To Object B Differently Depending On Context

    - by IanT8
    Calling all AutoMapper gurus! I'd like to be able to map object A to object B differently depending on context at runtime. In particular, I'd like to ignore certain properties in one mapping case, and have all properties mapped in another case. What I'm experiencing is that Mapper.CreateMap can be called successfully in the different mapping cases however, once CreateMap is called, the map for a particular pair of types is set and is not subsequently changed by succeeding CreateMap calls which might describe the mapping differently. I found a blog post which advocates Mapper.Reset() to get round the problem, however, the static nature of the Mapper class means that it is only a matter of time before a collision and crash occur. Is there a way to do this? What I think I need is to call Mapper.CreateMap once per appdomain, and later, be able to call Mapper.Map with hints about which properties should be included / excluded. Right now, I'm thinking about changing the source code by writing a non-static mapping class that holds the mapping config instance based. Poor performance, but thread safe. What are my options. What can be done? Automapper seems so promising.

  • Mark assembly App_licenses.dll with AssemblyVersion (FxCop CA1016 rule)

    - by user295479
    Hello everyone, I'm trying to fulfil FxCop's rules in my web site. Since I use some Infragistics controls I have a licenses.licx file that turns into a "app_licenses.dll" assembly after publication. The problem is that this app_licenses.dll assembly does not comply with rule CA1016 (MarkAssembliesWithAssemblyVersion), and I should add an AssemblyVersion attribute to 'App_Licenses.dll'. I found I can add an AssemblyInfo file to my web site and then reference it from the web.config file as following: <compilers> <compiler language="c#;cs;csharp" extension=".cs" compilerOptions="C:\....\AssemblyInfo.cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4"> <providerOption name="CompilerVersion" value="v3.5" /> <providerOption name="WarnAsError" value="false" /> </compiler> </compilers> AssemblyInfo.cs contains: using System; using System.Reflection; using System.Runtime.InteropServices; using System.Resources; [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")] [assembly: NeutralResourcesLanguageAttribute("es-ES")] NeutralResourcesLanguageAttribute worked for another auto-generated dll in the web site (app_GlobalResources.dll) for another FxCop rule, but app_licenses.dll seems to ignore the assembly info and still pops up the same CA1016 error. Any help would be much appreciated.

  • high performance hibernate insert

    - by luke
    I am working on a latency sensitive part of an application, basically i will receive a network event transform the data and then insert all the data into the DB. After profiling i see that basically all my time is spent trying to save the data. here is the code private void insertAllData(Collection<Data> dataItems) { long start_time = System.currentTimeMillis(); long save_time = 0; long commit_time = 0; Transaction tx = null; try { Session s = HibernateSessionFactory.getSession(); s.setCacheMode(CacheMode.IGNORE); s.setFlushMode(FlushMode.NEVER); tx = s.beginTransaction(); for(Data data : dataItems) { s.saveOrUpdate(data); } save_time = System.currentTimeMillis(); tx.commit(); s.flush(); s.clear(); } catch(HibernateException ex) { if(tx != null) tx.rollback(); } commit_time = System.currentTimeMillis(); System.out.println("Save: " + (save_time - start_time)); System.out.println("Commit: " + (commit_time - save_time)); System.out.println(); } The size of the collection is always less than 20. here is the timing data that i see: Save: 27 Commit: 9 Save: 27 Commit: 9 Save: 26 Commit: 9 Save: 36 Commit: 9 Save: 44 Commit: 0 This is confusing to me. I figure that the save should be quick and all the time should be spent on commit. but clearly I'm wrong. I have also tried removing the transaction (its not really necessary) but i saw worse times... I have set hibernate.jdbc.batch_size=20... i need this operation to be as fast as possible, ideally there would only be one roundtrip to the database. How can i do this?

  • Problems installing PHP's PECL sphinx module

    - by Camsoft
    I've installed the sphinx binaries and libraries and am now trying to install the PECL sphinx module. My system is running OS X 10.6 with MAMP 1.8.2 installed. I try to install sphinx using the following command: sudo pecl install sphinx The PECL command outputs the following: running: phpize Configuring for: PHP Api Version: 20090626 Zend Module Api No: 20090626 Zend Extension Api No: 220090626 The versions above don't match the versions listed when doing a phpinfo(). It seems that PECL is trying to complie against the built-in version of PHP. If I ignore the errors and continue the it will successfully compile and place the sphinx.so file in: /usr/lib/php/extensions/no-debug-non-zts-20090626/sphinx.so when in fact it should be: /Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20060613/ I've tried copying the sphinx.so file to the MAMP extensions dir but when I restart apache PHP displays the following warning: PHP Startup: Unable to load dynamic library '/Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20060613/sphinx.so I think this is because MAMP is 32bit and the built-in PHP is 64bit so PECL complies for 64bit. I might be completely wrong but I did read this when I goggled on the topic. Does anyone know how to get PECL to map to the MAMP version of PHP instead of the built-in version?
