• What is the sequence followed by the Linux kernel to configure a device?

  - by Jaime Soriano

  As I understood after reading the chapter related to The Linux Device Model in the Linux Device Drivers 3rd Edition, when a new device is configured, the kernel follows more or less this sequence: The Device is registered in the driver core (device_register(), what includes device initialization) A kobject is registered in the device model It provokes a hotplug event Bus and drivers are checked to see which one matches with the device Probe Device is binded to the driver My main doubt is, in step 1, when is device_register() called and what info should be yet in the device struct? Is it called by the bus to which the device is connected? Any example in the code? Have I misunderstood something? :)

• Automation of testing using JUnit

  - by Vijay Selvaraj

  Hi, i am trying to automate manual testing of modules in my project. We are dealing with IBM Websphere Message queue software. We have a trigger component written in core java which when executed polls for availability of message in the configured queue. Its an indefinite while loop that keeps the trigger component running. I have written test cases in JUnit to put message in the queue and now will i be able to start/stop the trigger component on demand? Invoking the trigger component keeps it running and i am not getting the control back to check the expected output. If i start it in thread then the log files to which the trigger component is supposed to update when processing the message is not getting updated. How can i resolve this situation. Your suggestion and directions is highly appreciated. Thanks, -Vijay

• Is it proper to get and especially set Perl module's global variables directly?

  - by DVK

  I was wondering what the best practice in Perl is regarding getting - or, more importantly, setting - a global variable of some module by directly accessing $Module::varName in case the module didn't provide getter/setter method for it. The reason it smells bad to me is the fact that it sort of circumvents encapsulation. Just because I can do it in Perl, I'm not entirely certain I should (assuming there actually is an alternative such as adding a getter/setter to the module). I'm asking this because I'm about to request an addition of a getter/setter for a global variable in one of the core Perl modules, and I would like to avoid it soundly and unanimously rejected on the grounds of "Why the heck do you need one when you can access the variable in the package directly?" - in case doing the latter is actually considered perfectly OK by the community.

• Django admin urls return INVALID REQUEST! - Django

  - by RadiantHex

  Hi folks, my admin urls are sat behind a prefix by doing the following. 1# (r'^admin/', include(admin.site.urls)), is placed within urls_core.py 2# (r'^api/', include('project.urls_core')), is palced within urls.py All admin URLs work fine except app indexes. If I go to any URL such as: /api/admin/core/ /api/admin/registration/ /api/admin/users/ /api/admin/filters/ I receive 'INVALID REQUEST' as my response. Status code is 200 (OK) though. I have never received this error message before. Does anyone have a clue? Thanks guys!

• Hibernate - hibernate.hbm2ddl.auto = validate

  - by azp74

  I am interested in how hibernate.hbm2ddl.auto=validate actually works and I am struggling to find comprehensive documentation. We've recently discovered production system was affected by http://opensource.atlassian.com/projects/hibernate/browse/HHH-3532 (Hibernate matches foreign keys on name, rather than signature and so will recreate them for you) and hibernate.hbm2ddl.auto=update is being removed from our next release. I would be quite happy to just get rid of hibernate.hbm2ddl.auto altogether and manage our database ourselves. However, not all my colleagues share this world view and some are keen to add back in hibernate.hbm2ddl.auto=validate. I'm concerned this will hit the same problem and I'm interested in finding more documentation about how this validation actually works. The Hibernate Community Documentation (http://docs.jboss.org/hibernate/core/3.3/reference/en/html/session-configuration.html) really just makes reference to the values. Does anyone have any good documentation pointers, or any real life experience of using validate in a production system?

• Slow insert speed in Postgresql memory tablespace

  - by Prashant

  Hi, I have a requirement where I need to store the records at rate of 10,000 records/sec into a database (with indexing on a few fields). Number of columns in one record is 25. I am doing a batch insert of 100,000 records in one transaction block. To improve the insertion rate, I changed the tablespace from disk to RAM.With that I am able to achieve only 5,000 inserts per second. I have also done the following tuning in the postgres config: Indexes : no fsync : false logging : disabled Other information: - Tablespace : RAM - Number of columns in one row : 25 (mostly integers) - CPU : 4 core, 2.5 GHz - RAM : 48 GB I am wondering why a single insert query is taking around 0.2 msec on average when database is not writing anything on disk (as I am using RAM based tablespace). Is there something I am doing wrong? Help appreciated. Prashant

• File Uploads with Turbogears 2

  - by William Chambers

  I've been trying to work out the 'best practices' way to manage file uploads with Turbogears 2 and have thus far not really found any examples. I've figured out a way to actually upload the file, but I'm not sure how reliable it us. Also, what would be a good way to get the uploaded files name? file = request.POST['file'] permanent_file = open(os.path.join(asset_dirname, file.filename.lstrip(os.sep)), 'w') shutil.copyfileobj(file.file, permanent_file) file.file.close() this_file = self.request.params["file"].filename permanent_file.close() So assuming I'm understanding correctly, would something like this avoid the core 'naming' problem? id = UUID. file = request.POST['file'] permanent_file = open(os.path.join(asset_dirname, id.lstrip(os.sep)), 'w') shutil.copyfileobj(file.file, permanent_file) file.file.close() this_file = file.filename permanent_file.close()

• Is Private Bytes >> Working Set normal?

  - by Jacob

  OK, this may sound weird, but here goes. There are 2 computers, A (Pentium D) and B (Quad Core) with almost the same amount of RAM running Windows XP. If I run the same code on both computers, the allocated private bytes in A never goes down resulting in a crash later on. In B it looks like the private bytes is constantly deallocated and everything looks fine. In both computers, the working set is deallocated and allocated similarly. Could this be an issue with manifests or DLLs (system)? I'm clueless. Also, I compiled the executable on A and ran it on B and it worked. Note: I observed the utilized memory with Process Explorer. Question: During execution (where we have several allocations and deallocations) is it normal for the number of private bytes to be much bigger (1.5 GB vs 70 MB) than the working set?

• .NET 4.0 project reference 2.0 assembly

  - by jamone

  I have a project in which I'd like to use some of the .NET 4.0 features but a core requirement is that I can use the System.Data.SQLite framework which is compiled against 2.X. I see mention of this being possible such as the accepted answer here but I don't see how to actually achieve this. When I just try and run my 4.0 project while referencing the 2.X assembly I get: Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information. What "additional configuration" is necessary?

• C/C++/Assembly Programatically detect if hyper-threading is active on Windows, Mac and Linux

  - by HTASSCPP

  I can already correctly detect the number of logical processors correctly on all three of these platforms. To be able to detect the number of physical processors/cores correctly I'll have to detect if hyperthreading is supported AND active (or enabled if you prefer) and if so divide the number of logical processors by 2 to determine the number of physical processors. Perphaps I should provide an example: A quad core Intel CPU's with hyperthreading enabled has 4 physical cores, yet 8 logical processors (hyperthreading creates 4 more logical processors). So my current function would detect 8 instead of the desired 4. My question therefore is if there is a way to detect whether hyperthreading is supported AND ENABLED?

• Objective-C partial implementation of classes in separate files

  - by Aran Mulholland

  I am using core data and am generating classes from my data model. I implement custom methods in these classes, however when i regenerate i generate over the top so i end up copying and pasting a bit. What i would like to do is split my implementation files ('.m') so i can have one header file with multiple '.m' files. then i can keep my custom methods in one and not have to worry about erasing them when i regenerate. I use this technique in .NET a lot with its partial keyword. Is there anything similar in objective-C

• Using Fluent NHibernate in commercial application

  - by Paja

  I want to use Fluent NHibernate in commercial desktop application, and I'm little concerned about the licensing. I've downloaded Fluent NHibernate precompiled binaries, and it contains this list of files: Antlr3.Runtime.dll Castle.Core.dll Castle.DynamicProxy2.dll FluentNHibernate.dll Iesi.Collections.dll log4net.dll NHibernate.dll NHibernate.ByteCode.Castle.dll I guess I will have to add all of these files to my Inno Setup script, which will install them on user's computer. But what should I do to comply to all of the licenses associated with each file? I'm sure I'm not the first who wants to use Fluent NHibernate in commercial application, so I hope I won't have to study each of the licenses. I'm not a lawyer.

• Limitations in running Ruby/Rails on windows

  - by johnc

  In the installation documentation to RoR it mentions that there are many limitations to running Ruby on Rails on Windows, and in some cases, whole libraries do not work. How bad are these limitations, should I always default to Linux to code / run RoR, and is Iron Ruby expected to fix these limitations or are they core to the OS itself? EDIT Thanks for the answer around installation and running on Linux, but I am really trying to understand the limitations in functionality as referenced in the installation documentation, and non-working libraries - I am trying to find a link to the comment, but it was referenced in an installation read me when I installed the msi package I think

• High CPU Usage with WebGL?

  - by shoosh

  I'm checking out the nightly builds of Firefox and Chromium with support of WebGL with a few demos and tutorials and I can't help but wonder about the extremely high CPU load they cause. A simple demo like this one runs at a sustained 60% of my dual core. The large version of this one maxes out the CPU to 100% and has some visible frame loss. Chromium seems to be slightly better than firefox but not by much. I'm pretty sure that if these were desktop application the CPU load would be negligible. So what's going on here? what is it doing? Running the simple scripts of these can't be that demanding. Is it the extra layer of security or something?

• NSFetchedResultsController titleForHeaderInSection with formatted NSDate

  - by Daniel Granger

  In my Core Data app I am using a FetchedResultsController. Usually to set titles for headers in a UITableView you would implement the following method like so: - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[<#Fetched results controller#> sections] objectAtIndex:section]; return [sectionInfo name]; } where [sectionInfo name] returns a NSString. my sectionKeyPath is based on an NSDate and this all works fine apart from the section headers it gives me are the raw date description strings (e.g. 12/12/2009 12:32:32 +0100) which look a bit of a mess in a header! So I want to use a date formatter on this to make a nice header like "Apr 17 2010" but I can't do that with the [sectionInfo name] as this is NSString! Any Ideas? Many Thanks

• Exec Maven Plugin to Command Line

  - by mistercaste

  I have an application developed in NetBeans/Maven that can be started via command line with: mvn exec:exec "-Dexec.executable=C:\\Java\\jdk1.6.0_33\\bin\\java.exe" "-Dexec.args=-Dlog4j.properties=... -classpath %classpath com.xxx.MyLauncher" -Dexec.classpathScope=runtime -Dexec.workingdir= Now I need to run the application through the standard java command line method, like: java -Dlog4j.properties=... -jar myapp-1.2-SNAPSHOT.jar Unfortunately this does not work in the same manner, as I get the following exception: opencard.core.util.OpenCardPropertyLoadingException: property file not found Questions: What is the difference between launching applications with the Exec-Maven-plugin and the standard java execution on command line? Is there an easy way to convert a Maven execution script to a standard command line? How to run the application succesfully?

• Maven problems using GAE and DataNucleus

  - by Wraith

  I'm having trouble retrieving 2 artifacts in my Maven/Java/Google App Engine project: com.google.appengine.orm:datanucleus-appengine:jar:1.0.7.final com.google.appengine:appengine-api-1.0-sdk:jar:1.3.4 There's a similar question posted, but each answer brings me back to the same error message. More detail I don't know if it is relevant, but rather than a version number, my original dependency for DataNucleus contained a variable. I am using Eclipse. <groupId>org.datanucleus</groupId> <artifactId>datanucleus-core</artifactId> <version>${datanucleus.version}</version> <scope>runtime</scope> I did not include my stack trace in Maven for brevity's sake. Please let me know if it would help to post it. Thank you.

• GTK+ (GTKSharp) poor performance in Windows

  - by nubela

  Hi, In my Mono (C#) project that is meant to be cross-platform, I am using the GTK for the UI. However one thing I noticed is, on my netbook in Archlinux, the performance is really speedy, so events such as mouse hover, and redrawing of widgets, etc, are really fast. Compared to windows (7) on dual core CPUs, the performance is really really weak. Which perplexes me. Am I doing something wrong that is warranting this difference in performance between OSes? What are some ways I can do to optimize GTK on Windows? Its really bad to take around 0.5 secs for a hover event to kick in whereas its almost immediate on a weak(er) netbook with Linux. My code is here for the GUI layer: http://code.google.com/p/subsynct/source/browse/branches/dev/subsync#subsync/GUI Thanks!

• Why is J2ee/EJBs a dying Trend?

  - by Taranfx

  I might be wrong on this, but I no longer see heavy Business and Web services being hosted using J2ee technologies (Especially EJBs). Having known the power and scalability of J2ee applications, what is keeping developers/decision makers to restrict themselves to Core Java (POJOs) or even other web technologies like PHP, python. Is it the development time? Is it the Ease of configuration? (I feel this should not be a strong reason with Java EE 6, things are simplified) Of course scripting languages are faster to develop, we cannot ignore the fact that they are inherently not-as-scalable as Java Applications are (using App servers)

• UITabBarController With UINavigationController "more" Tab Issue

  - by Medlay

  UITabBarController with UINavigationController "more" tab issue There is a problem with using UINavigationController in UITabBarController. I have a TabBar  with 6 items. Of course, a standart item "more" appears, and there are two UINavigationControllers that didn't fit in a TabBar. The core of the problem is: when I'm working with visible items (a first four), UIViewController can be pushed  in an UINavigationController: [self.navigationController pushViewController:userDataViewController animated:YES]; If you call on in "more" and rearrange items in such way, that a visible UINavigationController gets into "more", when calling on it userDataViewController appears.  This  userDataViewController is the last, which has got in a stack and a Back button leads back to "more", but not to the controllers, that were before a userDataViewController appeared. I understand that in fact a selector pushViewController is called from "more", and it pushes my UINavigationController in a stack, and it's not good. Maybe, someone has faced such problem and could help me to solve it? Thank you forward.

  I'm trying to use the EWS API to access an Exchange server from a console program i'm writing. I've specified the type of exchange server i'm connecting to but when I try to execute the code i have, it gives me Error 1 The type 'System.TimeZoneInfo' is defined in an assembly that is not referenced.

I'm moderately new to programming in C# so some of the stuff is still confusing. Thanks.
