• MySQL InnoDB insertion is very slow

  - by dharmapurikar

  We use MySQL server 5.1.43 64-bit edition. InnoDB is used as engine. We have a sql script which we execute every time we build the application. On ubuntu machine with MySQL server and InnoDB engine it takes about 55 seconds to complete the execution. If I run the same script on OSX, it takes close to 3 minutes! Any ideas why OSX is so slow while executing this script?

• Up to date, JPA compliant GenericDAO Implementation

  - by HDave

  I read this article: http://www.ibm.com/developerworks/java/library/j-genericdao.html several times and believe I understand what it is saying. However, it is 4 years old and I have a JPA compliant Java application to contend with. In addition, I see that there is a JPATemplate in Spring that has some good functionality, but the Spring documentation says it is already deprecated! Can anybody point me to a solid, modern, JPA compliant, Spring based, working example of a GenericDAOImpl that proxies an Interface to provide generic finder execution?

• How can a WF4 Custom Activity determine that its in design mode v. executing mode

  - by Preet Sangha

  I have a WF4 custom activity with a custom designer (WPF). I would like to have slightly different behaviour in the CacheMetaData override depending on if the Activity is in Design or Execution mode. Since the Activity can be debugged, it could in be VS in either case so I cannot check for that. Is there a service within WF4 I can call to tell what mode I'm in please?

• Command line semaphore utility

  - by compie

  I want to write a command line utility that can be used to synchronize the execution off programs in different consoles. Console A: $ first_program && semaphore -signal Console B: $ semaphore -wait && second_program The first program takes a long take to complete. The second program can only start when the first program has finished. Which synchronization object do I need to implement this (in Python)?

• When to address managed heap fragmentation

  - by emddudley

  I was reading a blog entry by Josh Smith where he used a cache mechanism in order to "reduce managed heap fragmentation". His caching reduces the number of short-lived objects being created at the cost of slightly slower execution speed. How much of a problem is managed heap fragmentation in a managed language like C#? How can you diagnose if it's an issue? In what situations would you typically need to address it?

• Maven building for GoogleAppEngine, forced to include JDO libraries?

  - by James.Elsey

  Hi, I'm trying to build my application for GoogleAppEngine using maven. I've added the following to my pom which should "enhance" my classes after building, as suggested on the DataNucleus documentation <plugin> <groupId>org.datanucleus</groupId> <artifactId>maven-datanucleus-plugin</artifactId> <version>1.1.4</version> <configuration> <log4jConfiguration>${basedir}/log4j.properties</log4jConfiguration> <verbose>true</verbose> </configuration> <executions> <execution> <phase>process-classes</phase> <goals> <goal>enhance</goal> </goals> </execution> </executions> </plugin> According to the documentation on GoogleAppEngine, you have the choice to use JDO or JPA, I've chosen to use JPA since I have used it in the past. When I try to build my project (before I upload to GAE) using mvn clean package I get the following output [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Failed to resolve artifact. Missing: ---------- 1) javax.jdo:jdo2-api:jar:2.3-ec Try downloading the file manually from the project website. Then, install it using the command: mvn install:install-file -DgroupId=javax.jdo -DartifactId=jdo2-api -Dversion=2.3-ec -Dpackaging=jar -Dfile=/path/to/file Alternatively, if you host your own repository you can deploy the file there: mvn deploy:deploy-file -DgroupId=javax.jdo -DartifactId=jdo2-api -Dversion=2.3-ec -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id] Path to dependency: 1) org.datanucleus:maven-datanucleus-plugin:maven-plugin:1.1.4 2) javax.jdo:jdo2-api:jar:2.3-ec ---------- 1 required artifact is missing. for artifact: org.datanucleus:maven-datanucleus-plugin:maven-plugin:1.1.4 from the specified remote repositories: __jpp_repo__ (file:///usr/share/maven2/repository), DN_M2_Repo (http://www.datanucleus.org/downloads/maven2/), central (http://repo1.maven.org/maven2) [INFO] ------------------------------------------------------------------------ [INFO] For more information, run Maven with the -e switch [INFO] ------------------------------------------------------------------------ [INFO] Total time: 3 seconds [INFO] Finished at: Sat Apr 03 16:02:39 BST 2010 [INFO] Final Memory: 31M/258M [INFO] ------------------------------------------------------------------------ Any ideas why I should get such an error? I've searched through my entire source code and I'm not referencing JDO anywhere, so unless the app engine libraries require it, I'm not sure why I get this message.

• How can I build multiple processes with TBB?

  - by Jackie

  Now I plan to parallelize my sequential solver. I hope I could run several copies of my solver(maybe with different parameters) in parallel simultaneously on a multi-core computer. can I do this with TBB? The reason I ask this question is that the book says: do not introduce anything in your code that will not allow single-thread execution. Any experts can explain this issue? Thanks.

• Web Services API Versioning

  - by Paul Izzy

  I offer a small Web Services API to my clients which I plan to evolve over time. So I need some sort of versioning, but I can't find any information about how you do something like that. Is there a best practise? How can I keep adding new functionality without breaking compatibility with the web services consumers?

• How to get hibernate3-maven-plugin hbm2ddl to find JDBC driver?

  - by HDave

  I have a Java project I am building with Maven. I am now trying to get the hibernate3-maven-plugin to run the hbm2ddl tool to generate a schema.sql file I can use to create the database schema from my annotated domain classes. This is a JPA application that uses Hibernate as the provider. In my persistence.xml file I call out the mysql driver: <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/> When I run Maven, I see it processing all my classes, but when it goes to output the schema, I get the following error: ERROR org.hibernate.connection.DriverManagerConnectionProvider - JDBC Driver class not found: com.mysql.jdbc.Driver java.lang.ClassNotFoundException: com.mysql.jdbc.Driver I have the MySQL driver as a dependency of this module. However it seems like the hbm2ddl tool cannot find it. I would have guessed that the Maven plugin would have known to search the local Maven file repository for this driver. What gives? The relevant part of my pom.xml is this: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>hibernate3-maven-plugin</artifactId> <executions> <execution> <phase>process-classes</phase> <goals> <goal>hbm2ddl</goal> </goals> </execution> </executions> <configuration> <components> <component> <name>hbm2ddl</name> <implementation>jpaconfiguration</implementation> </component> </components> <componentProperties> <persistenceunit>my-unit</persistenceunit> </componentProperties> </configuration> </plugin>

• Slow (to none) performance on SQL 2005 after attaching SQL 2000 database

  - by ploft

  Issue: Using the detach/attach SQL database from a SQL 2000 SP4 instance to a much beefier SQL 2005 SP2 server. Run reindex, reorganize and update statistics a couple of times, but without any success. Queries on SQL 2000 took about 1-2 sec. to complete, now the same queries take 2-3 min on the SQL 2005 (and even 2008 - tested it there also). Have looked at the execution plans and the overall percent matches or are alike on each server.

• How to restrict rightBarButtonItem size in UINavigationBar ?

  - by lefakir

  I create a rightBarButtonItem with this method : - (UIBarButtonItem *)customBarButtonWithSelector:(SEL)callback { UIButton *customButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; customButton.bounds = CGRectMake(0, 0, 30.0f, 30.0f); return [[[UIBarButtonItem alloc] initWithCustomView:customButton] autorelease]; } At execution time the selector is fired when the bar is touched outside the button (near the middle). Is there a way to restrict the event responder in the defined bounds or in a acceptable range ?

• Adding an HTTP Header to the request in a servlet filter

  - by Mason

  I'm integrating with an existing servlet that pulls some properties out of the HTTP header. Basically, I'm implementing an interface that doesn't have access to the actual request, it just has access to a map of k-v for the HTTP headers. I need to pass in a request parameter. The plan is to use a servlet filter to go from parameter to header value but of course the HttpServletRequest object doesn't have an addHeader() method. Any ideas?

• Are there Java libraries to do drag and drop

  - by Kenston

  Hello. Are there open source libraries for Java to make implementation of drag and drop easier? I plan to make something like the one shown below: The program is Alice, where you can drag some elements on the left and nest them to the right. It's open source, but they did not use any libraries I think. I'm wondering if we anyone know of open source frameworks that work this way, or assist in doing complex drag and drops.

• Store PHP Exceptions in array

  - by Industrial

  Hi everyone, I am really not sure if this is the right way to go, since exceptions is really a fresh subject to me. Is it possible to catch multiple exceptions (let the execution of the script continue) and then store the exceptions in a array to be able to return all exceptions caused? By that said, it would be awesome to be able to use exceptions to more than just showing an error that kills the application (script) Thanks!

• CSS: achieving TWO-WAY infinite scroll with mouse drag

  - by Miguel Ping

  Hi, I'm trying to create an infinite scroll component. I'm using this site as a tutorial, but it seems that I can only get the infinite scroll on one way, because when I add elements to the leftmost side, the scrollLeft property auto-adjusts thus the page gets a quirky scroll, jumping instead of making a smooth movement. Is there any way of achieving infinite scroll both-ways? I don't plan to use scrolling buttons, just mouse drag for moving the scroll view.

• How can I trace a variable at runtime in C#?

  - by luvieere

  How can I track a variable's values as they change, at runtime, in C#? I'm interested in the same functionality that the debugger provides when I'm tracing a variable through execution steps, only that I need to call upon it from my code. Some sort of key-value observing, but for all kinds of variables(local, class, static, etc), not only properties. So, basically, receive a notification when a variable's value changes.

• C - equivalent of .NET Console.ReadLine

• How do I stop myself from redesigning my Silverlight screens? Is there a theme that looks like Sket

  - by Dan Ryan

  Whilst working in Silverlight I am always fighting the urge to work on the screen design rather than coding the behaviour (which is what I should be doing). My cunning plan is to find a theme that looks something like MS SketchFlow or Balsamiq which will remind me of the draft nature of the screens whilst being somewhat prettier than the default look & feel of Silverlight. Does anyone know of such a theme? Alternatively can anyone give advise on how they overcame there design addiction :) Thanks, Dan

• How to optimize my PostgreSQL DB for prefix search?

  - by asmaier

  I have a table called "nodes" with roughly 1.7 million rows in my PostgreSQL db =#\d nodes Table "public.nodes" Column | Type | Modifiers --------+------------------------+----------- id | integer | not null title | character varying(256) | score | double precision | Indexes: "nodes_pkey" PRIMARY KEY, btree (id) I want to use information from that table for autocompletion of a search field, showing the user a list of the ten titles having the highest score fitting to his input. So I used this query (here searching for all titles starting with "s") =# explain analyze select title,score from nodes where title ilike 's%' order by score desc; QUERY PLAN ----------------------------------------------------------------------------------------------------------------------- Sort (cost=64177.92..64581.38 rows=161385 width=25) (actual time=4930.334..5047.321 rows=161264 loops=1) Sort Key: score Sort Method: external merge Disk: 5712kB -> Seq Scan on nodes (cost=0.00..46630.50 rows=161385 width=25) (actual time=0.611..4464.413 rows=161264 loops=1) Filter: ((title)::text ~~* 's%'::text) Total runtime: 5260.791 ms (6 rows) This was much to slow for using it with autocomplete. With some information from Using PostgreSQL in Web 2.0 Applications I was able to improve that with a special index =# create index title_idx on nodes using btree(lower(title) text_pattern_ops); =# explain analyze select title,score from nodes where lower(title) like lower('s%') order by score desc limit 10; QUERY PLAN ------------------------------------------------------------------------------------------------------------------------------------------ Limit (cost=18122.41..18122.43 rows=10 width=25) (actual time=1324.703..1324.708 rows=10 loops=1) -> Sort (cost=18122.41..18144.60 rows=8876 width=25) (actual time=1324.700..1324.702 rows=10 loops=1) Sort Key: score Sort Method: top-N heapsort Memory: 17kB -> Bitmap Heap Scan on nodes (cost=243.53..17930.60 rows=8876 width=25) (actual time=96.124..1227.203 rows=161264 loops=1) Filter: (lower((title)::text) ~~ 's%'::text) -> Bitmap Index Scan on title_idx (cost=0.00..241.31 rows=8876 width=0) (actual time=90.059..90.059 rows=161264 loops=1) Index Cond: ((lower((title)::text) ~>=~ 's'::text) AND (lower((title)::text) ~<~ 't'::text)) Total runtime: 1325.085 ms (9 rows) So this gave me a speedup of factor 4. But can this be further improved? What if I want to use '%s%' instead of 's%'? Do I have any chance of getting a decent performance with PostgreSQL in that case, too? Or should I better try a different solution (Lucene?, Sphinx?) for implementing my autocomplete feature?
