• Performance Overhead of Perf Event Subsystem in Linux Kernel

  - by Bo Xiao

  Performance counters for Linux are a new kernel-based subsystem that provide a framework for all things performance analysis. It covers hardware level (CPU/PMU, Performance Monitoring Unit) features and software features (software counters, tracepoints) as well. Since 2.6.33, the kernel provide 'perf_event_create_kernel_counter' kernel api for developers to create kernel counter to collect system runtime information. What I concern most is the performance impact on overall system when tracepoint/ftrace is enabled. There are no docs I can find about them. I was once told that ftrace was implemented by dynamically patching code, will it slow the system dramatically?

• HQL updates and domain objects

  - by CaptainAwesomePants

  I have what may be a pretty elementary Hibernate question. Do HQL (and/or Criteria) update queries cause updates to live domain objects? And do they automatically flush now-invalid domain objects from the first-level cache? Example: Player playerReference1 = session.get(Player.class,1); session.createQuery("update players set gold = 100").executeUpdate(); //Question #1 -- does playerReference1.getGold() now return 100? Player playerReference2 = session.get(Player.class,1); //Question #2 -- does playerReference2.getGold() return 100, or is it the same exact object? Should I make a practice of evicting all objects that are affected by an HQL update if there's a chance some code will need it later?

• Incompatible classes when loading SWF

  - by Bart van Heukelom

  I have two ActionScript 3 projects, game(.swf) and minigame(.swf). At runtime the main game loads the minigame via Loader. I also have a shared library (SWC) of event classes, included by both, which minigame will need to dispatch and game will need to listen to. First: Is this possible this way? Second: What will happen if I compile the minigame, then change the event classes so they're incompatible, then compile the main game. Will Flash crash when trying to load the minigame SWF? (I hope so) Third: And what will happen if I change the event classes, but in a way that preserves interface-level compatibility?

• Windows Phone 7 and C++/CLI

  - by Fabio Ceconello

  Microsoft recently released tools and documentation for its new Phone 7 platform, which to the dismay of those who have a big C++ codebase (like me) doesn't support native development anymore. Although I've found speculation about this decision being reversed, I doubt it. So I was thinking how viable would be to make this codebase available to Phone 7 by adapting it to compile under C++/CLI. Of course the user interface parts couldn't be ported, but I'm not sure about the rest. Anyone had a similar experience? I'm not talking about code that does heavy low-level stuff - but there's a quite frequent use of templates and smart pointers.

• App Engine: Launching a script upon update/run

  - by kovshenin

  Hi all. I'm working with App Engine and I'm thinking about using the LESS CSS extension in my next project. There's no good LESS CSS library written in Python so I went on with the original Ruby one which works great and out of the box. I'd like App Engine to execute lessc ./templates/css/style.less before running the development server and before uploading the files to the cloud. What is the best way to automate this? I'm thinking: #run.sh: lessc ./templates/css/style.less .gae/dev_appserver.py --use_sqlite . And #deploy.sh lessc ./templates/css/style.less .gae/appcfg.py update . Am I on the correct path or is there a more elegant way of doing things, perhaps at the appcfg.py level? Thanks.

• Loading UINavigationController from another nib automatically by UITabBarController

  - by porneL

  I think I've found the cause: Document Info window in IB has a warning: "'Selected Navigation Controller (Second)' has nib name property set to 'SecondView.nib', but this view controller is not intended to have its view set in this manner." Bummer. I've built nib in Interface Builder that has UITabBarController at top level and switches between UINavigationControllers. It works fine when everything is in a single nib file, but I'd like to use separate nib files for UINavigationControllers. Starting with Apple's TabBar template, if I just change class of SecondView to UINavigationController, it all breaks: and all I get is this: Is it possible to have separate file for UINavigationController without programmatically setting everything? I would like TabBarController to handle loading and unloading of nibs.

• How to have tortoisesvn Always freeze svn:externals for tags

  - by dnndeveloper

  Is this possible with tortoiseSVN?: Always freeze svn:externals for tags the scenario is our trunk will always use the 'head' revision for externals, however when we create 'tags' we would like for them to have a revision set for externals to properly 'freeze' them at a specific point in time. Thanks! Update Thanks to everyone for your feedback/info. Since I could not find anything that would completely meet our needs (tried smartsvn and svncopy.pl) I made a console app that so far has passed all our test cases. A high level overview: The app takes a repository URL then looks for all externals and adds the last commit revision for them - I do a "svn info" and get the "commit revision". The app works with both folder and single file externals. Here is the source code and complete setup files: http://svnxf.codeplex.com/

• How to change password hashing algorithm when using spring security?

  - by harry

  I'm working on a legacy Spring MVC based web Application which is using a - by current standards - inappropriate hashing algorithm. Now I want to gradually migrate all hashes to bcrypt. My high level strategy is: New hashes are generated with bcrypt by default When a user successfully logs in and has still a legacy hash, the app replaces the old hash with a new bcrypt hash. What is the most idiomatic way of implementing this strategy with Spring Security? Should I use a custom Filter or my on AccessDecisionManager or …?

• Has anyone managed to get Visual Studio 2003 running on Windows 7?

  - by Jeremy White

  Yes, I know... I could set up a virtual machine running XP. Unfortunately our build environment is such that we need to be running VC2003, 2005 and 2008 concurrently and it would be much more convenient if I could run 2003 natively on Windows 7 for the few projects we have that require it. I realize some things may not be available in the IDE, but I was able to run 2003 under windows Vista and if I could get the same base level of functionality under Windows 7 I would be extremely happy. Right now I get an error opening the *.pdb file when I compile after switching vc2003 to run as Administrator under compatibility mode for XP SP 2. Thanks!

• Managing Large Database Entity Models

  - by ChiliYago

  I would like hear how other's are effectively (or not) working with the Visual Studio Entity Designer when many database tables exists. It seems to me that navigating the Designer is tough enough to find what you are looking for with just a few tables but how about a database with say 100 to 200 tables? When a table change is made at the database level how is the model updated? Does it overwrite any manual changes you have made to the model? How would you quickly find an entity in the designer to make a change or inspect a change? Seems unrealistic to be scrolling around looking for specific entity. Thanks for your feedback!

• What data/service is where?

  - by MrTelly

  What management tools (open source or otherwise) are there to track the location of data, the services that deliver/use that data and the services themselves. If you believe the snake oil a combination of DB, ESB and SOA will deliver anything anywhere, but how do you know what's where. BTW I'm not interested at the WSDL level, I'm thinking of a tool that the users/BA community would populate and use. A combination of SOA and Database is now the bedrock of most applications, however what used to be called Data Dictionaries, and would now be Service Catalogues? or MetaData repositories still seem to live in purely DataCentric world.

• Scrum for Team System 2010 - How to use story points instead of Hours

  - by dretzlaff17

  I have installed TFS 2010 using the Scrum for Team System v3. The work item templates want you to enter a Project Backlog Item that includes story points, then you need to add linked tasks as a child of the PBI. It is at the task level where you can assign team individuals, update estimated hours left, etc. What is the importance of the Story Points used at the PBI item if individual tasks are using hours? Has anyone customized this template so that the child work item tasks use story point burn downs instead of hours? Also, I would be nice to have the total number of story points from each individual task roll up into the PBI item as a read only field for total story points. Thanks for your time.

• What Kind of Knowledge is Necessary For a Permon Who Does Not Have IT Background? [closed]

  - by skyflyer

  One of my colleagues joined our company, which by the way is a internet company, months ago as an on-line marketing specialist. He majored English in his college and has never deeply touched IT before. He says that to be a good on-line marketing specialist he needs to lean some basic IT skills in order to deliver superb work. According to him, things like Search Engine Optimization, monitoring competitors' web sites, design some functionality on web site and so on require IT entree-level knowledge. And he asks me what kind knowledge is helpful for him to do his job. I am stunted by his question. It is easy enough to answer, things like HTML, CSS, even Photo-shop are required in some job descriptions. Also, I believe some basic understanding of dynamic web site, static web site is helpful to him. On the other hand, as a techie I still feel my answer is awkward. What is your opinion on this? Always lot of thanks to you guys on SO.

• Javascript form validation/sanitizing do i need regex here ?

  - by user318144

  I have a single form input that is for checking domains. Sometimes people type in www. before the domain or .com after the domain name. The service that i use to check availability automatically checks for all top level domains so when people add the .com at the end it becomes redundant. For example the string submitted is domainname.com.com which is clearly invalid. I understand you can do this on the server side but due to some rather weird circumstance i must use javascript for this. So is regex the solution here ? If so is there some kind of regex generator i can use for this or can someone point me in the right direction with a code snippet perhaps ? Appreciate any help thanks!

• How to estimate memory need by XPathDocument for a specific xml file

  - by bill seacham

  Is there any way to estimate the memory requirement for creating an XpathDocument instance based on the file size of the xml? XpathDocument xdoc = new XpathDocument(xmlfile); Is there any way to programmatically stop the process of creating the XpathDocument if memory drops to a very low level? Since it loads the entire xml into memory, it would be nice to know ahead of time if the xml is too big. What I have found is that when I create a new XpathDocument with a big xml file, an outofmemory exception is never fired, but that the process slows to a crawl, only 5 Mb of memory remains a available and the Task Manager reports it is not responding. This happened with a 266 Mb xml file when there was 584 Mb of ram. I was able to load a 150 Mb file with no problems in 18. After loading the xml, I want to do xpath queries using an XpathNavigator and an XpathNodeIterator. I am using .net 2.0, xp sp3.

• RewriteRule being greedy

  - by lardlad

  I have been looking for an answer for a few hours now, so sorry if this was asked a ton of times, I missed it. I basically want to make a rewrite to ignore the first directory. That first dir in the path will be different so I thought I could use a regex. But my regex is matching all the way to the file name: RewriteRule ^([a-z]+)?/(.+)$ $2 [L] this works if I am one level deep: http://test.domain.com/one/index.php I get the actual index page of the root. Which is what I want. but if I were to go deeper: http://test.domain.com/one/two/index.php I get a message saying /index.php was not found. So it seems my regex is not stopping after the last [a-z]. I appreciate any help. This is Apache2 if that matters at all.

• XNA 2d camera with arbitrary zoom center

  - by blooop

  I have a working 2D camera in XNA with these guts: ms = Mouse.GetState(); msv = new Vector2(ms.X, ms.Y); //screenspace mouse vecor pos = new Vector2(0, 0); //camera center of view zoom_center = cursor; //I would like to be able to define the zoom center in world coords offset = new Vector2(scrnwidth / 2, scrnheight / 2); transmatrix = Matrix.CreateTranslation(-pos.X, -pos.Y, 0) * Matrix.CreateScale(scale, scale, 1) * Matrix.CreateTranslation(offset.X, offset.Y, 0); inverse = Matrix.Invert(transmatrix); cursor = Vector2.Transform(msv, inverse); //the mouse position in world coords I can move the camera position around and change the zoom level (with other code that I have not pasted here for brevity). The camera always zooms around the center of the screen, but I would like to be able to zoom about an arbitrary zoom point (the cursor in this case), like the indie game dyson http://www.youtube.com/watch?v=YiwjjCMqnpg&feature=player_detailpage#t=144s I have tried all the combinations that make sense to me, but am completely stuck.

• Making the #include square

  - by David

  I'm trying to write a makefile using CC on Solaris 10. [Only the first bit of that really matters, I think]. I have the following rule for foo.o: foo.o: foo.cc common_dependencies.h CC -c foo.cc -I../../common Unfortunately, common_dependencies.h includes all sorts of idiosyncratic trash, in directories not named '.' or '../../common' . Is this just going to have to be a brute force makefile where I ferret out all of the dependency paths? All of the dependencies are somewhere under '../..', but sometimes 1-level down and sometimes 2-levels down.

• Closing a dialog form closes the application

  - by user361633

  bool CheckAnswer() { DialogForm dialogForm = new DialogForm(); if (dialogForm.showDialog() == System.Windows.Forms.DialogResult.OK) return true; } The dialog form is invoked by a form created in the main form. When i close the dialog form the application is closed, not just the dialog form! If i invoke the dialog form in other form it works normally. The form from which i invoke the dialog form is top level, but even if i change that i'm getting the same result. Does anyone know what's wrong?

• Is there a graphics/game engine that supports PC & Mac?

  - by Chris Masterton

  Is their a graphics that runs on both Mac & PC? I've seen Unity and thats a possibility, I'm wondering if there are any other choices. Ideally I want to port the same C++ game code to both PC & Mac platforms, but let the underlying game/graphics engine take advantage of the appropriate hardware. edit: I'm looking on the level of Torque, Gamebryo & Unreal. A commercial solution is perfectly acceptable. Thanks, Chris

• Single OpenID Across Sub-Domains

  - by rockinthesixstring

  I'm using OpenID much the same as here on StackOverflow to authenticate my users. What I really need to be able to do though is have that OpenID work across all sub-domains of my site. The site behaves much the same as Kijiji in that each region has it's own subdomain calgary.example.com toronto.example.com vancouver.example.com etc When a user logs into "calgary" and later logs into "toronto", they will be forced to "give permission" at the provider, thus resulting in a new OpenID and resulting also in a new login. My app "can" have multiple OpenID's under one account, but that would become cumbersome to manage. Is there a way to have the provider link up to the top level domain and subsequently work across all sub-domains? I'm using DotNetOpenAuth.

• Other SecurityManager implementations available?

  - by mhaller

  Is there any other implementation (e.g. in an OSS project) of a Java SecurityManager available which has more features than the one in the JDK? I'm looking for features like configurable at runtime policies updateable at runtime, read from other data sources than a security.policy file Thread-aware, e.g. different policies per Thread Higher-level policies, e.g. "Disable network functions, but allow JDBC traffic" Common predefined policies, e.g. "Allow read-access to usual system properties like file.encoding or line.separator, but disallow read-access to user.home" Monitoring and audit trace logging, e.g. "Log all file access, log all network access going NOT to knownhost.example.org" Blocking jobs "requesting" a permission until an administrator grants permission, letting the thread/job continue ... I'm pretty sure that application servers (at least the commercial ones) have their own SecurityManager implementation or at least their own policy configuration. I'm wondering if there is any free project with similar requirements.

• Curious: Could LLVM be used for Infocom z-machine code, and if so how? (in general)

  - by jonhendry2

  Forgive me if this is a silly question, but I'm wondering if/how LLVM could be used to obtain a higher performance Z-Machine VM for interactive fiction. (If it could be used, I'm just looking for some high-level ideas or suggestions, not a detailed solution.) It might seem odd to desire higher performance for a circa-1978 technology, but apparently Z-Machine games produced by the modern Inform 7 IDE can have performance issues due to the huge number of rules that need to be evaluated with each turn. Thanks! FYI: The Z-machine architecture was reverse-engineered by Graham Nelson and is documented at http://www.inform-fiction.org/zmachine/standards/z1point0/overview.html

• Windows 7 UAC elevation

  - by Goz

  I have a single thread that I'd like to run as an administrator in my application. The rest of the application I can happily run as the default user level (asInvoker). Is this possible? I notice there is an "ImpersonateLoggedOnUser" function. Can I somehow use this to log the administrator on and then get the thread to impersonate that person? It seems as though this ought to be something pretty trivial to do ... but there doesn't appear to be any obvious way to do it. Can anyone help me out?
