• Sql Server 2000 Stored Procedure Prevent Parallelism or something?

  - by user187305

  I have a huge disgusting stored procedure that wasn't slow a couple months ago, but now is. I barely know what this thing does and I am in no way interested in rewriting it. I do know that if I take the body of the stored procedure and then declare/set the values of the parameters and run it in query analyzer that it runs more than 20x faster. From the internet, I've read that this is probably due to a bad cached query plan. So, I've tried running the sp with "WITH RECOMPILE" after the EXEC and I've also tried putting the "WITH RECOMPLE" inside the sp, but neither of those helped even a little bit. When I look at the execution plan of the sp vs the query, the biggest difference is that the sp has "Parallelism" operations all over the place and the query doesn't have any. Can this be the cause of the difference in speeds? Thank you, any ideas would be great... I'm stuck.

• Is code clearness killing application performance?

  - by Jorge Córdoba

  As today's code is getting more complex by the minute, code needs to be designed to be maintainable - meaning easy to read, and easy to understand. That being said, I can't help but remember the programs that ran a couple of years ago such as Winamp or some games in which you needed a high performance program because your 486 100 Mhz wouldn't play mp3s with that beautiful mp3 player which consumed all of your CPU cycles. Now I run Media Player (or whatever), start playing an mp3 and it eats up a 25-30% of one of my four cores. Come on!! If a 486 can do it, how can the playback take up so much processor to do the same? I'm a developer myself, and I always used to advise: keep your code simple, don't prematurely optimize for performance. It seems that we've gone from "trying to get it to use the least amount of CPU as possible" to "if it doesn't take too much CPU is all right". So, do you think we are killing performance by ignoring optimizations?

• Getting user data from Active Directory using PL/SQL

  - by David Neale

  I had a discussion today regarding an Oracle procedure I wrote some time ago. I wanted to get 7500 user email addresses from Active Directory using PL/SQL. AD will return a maximum of 1000 rows and the LDAP provider used by Oracle will not support paging. Therefore, my solution was to filter on the last two characters of the sAMAccountName (*00,*01,*02...etc.). This results in 126 queries (100 for account names ending in digits, 26 for those ending in a letter...this was sufficient for my AD setup). The person I was speaking to (it was a job interview by the way) said he could have done it a better way, but he would not tell me what that method was. Could anybody hazard a guess at what this method was?

• Does anyone has the experience of using the new p4 replicate command in their Perforce back-up /rest

  - by Thomas Corriol

  Hi all, we recently performed an upgrade of our whole perforce system to 2009.02 During this exercise, we noticed that the back-up /restore process that was installed here by the Perforce consultant a year ago was not completely working. Basically, the verify command has never worked (scary !). As we are obliged to revisit our Back-Up/Restore scripts, I was toying with the idea of using the new p4 replicate command. The idea is to use it alongside an rsync of the data files, so that in case of crash we will lose at worst an hour of work (if we execute them every hour). Does anyone has the experience or an example of back-up/restore scripts using the p4 replicate command of the 2009.02 version ? Thanks, Thomas

• Overloading Controller Actions

  - by DaveDev

  Hi Guys I was a bit surprised a few minutes ago when I tried to overload an Action in one of my Controllers I had public ActionResult Get() { return PartialView(/*return all things*/); } I added public ActionResult Get(int id) { return PartialView(/*return 1 thing*/); } .... and all of a sudden neither were working I fixed the issue by making 'id' nullable and getting rid of the other two methods public ActionResult Get(int? id) { if (id.HasValue) return PartialView(/*return 1 thing*/); else return PartialView(/*return everything*/); } and it worked, but my code just got a little bit ugly! Any comments or suggestions? Do I have to live with this blemish on my Controllers? Thanks Dave

• iPad as programming platform--What future do touch screens have with programming?

  - by user94154

  I read this question a few weeks ago. I thought about it when I first saw the iPad. Do you think it would be possible to set up a development environment on the iPad? I think it would be awesome if there was an InstantRails App, a Django App, maybe even 280 North's Atlas could run on it :). Would you develop using an on-screen keyboard and a 10 inch screen? Steve Jobs seems to think touch-screens are the future of web browsing. What Future does touch have with programming?

• Is there a good reason Uni courses still use "academic" languages like modula2?

  - by Cheeso

  This question prompts me to ask - why do universities still teach in languages like Modula2, when improved modern languages are available for free? Are there uni's that still teach Pascal, for example? I mean, it was good 30 years ago, but... now? Why? Why not Java, C#, Haskell? Related: Is it backwards to still teach LISP? Is this a duplicate question? If not, I think it ought to be a community wiki topic.

• Weird <T> Activator Question.

  - by j-t-s

  Hello, I'm sorry, but a while ago I wrote a piece of code that was so nice. And now I'm trying to remember it for a new project. All I can remember about it is that it looked something like this: public static Create<T>() *something missing here* : *Something missing here* { // add methods etc here. I also think I remember something like " Activator.CreateInstance" being used. But I'm not sure. } Has anybody written code like this before? Basically what it did was it created a control and passed it back to another project. Thank you jt

• PHP getting blank pages after submit a form + signal Segmentation fault (11)

  - by Ole Media

  I few days ago I update my macbook pro to snow leopard, and since then some php files are not showing. This is what happens: I created a php form, when going to 'http://localhost/webform.php' I can see the form just fine. Then, once I submit the form, I just get a blank page. I enable error and warnings reporting under php.ini to make sure I'm not missing something, but still I'm not getting anything, just the blank page. Then I checked under apache log files, and what I notice is that every time I submit the form I see the following line coming up under the apache logs: [Wed Apr 07 21:40:28 2010] [notice] child pid 70223 exit signal Segmentation fault (11) I'm clueless on this one. Any ideas on how to fix it?

• Weblogic server lib VS instance libext

  - by Sebastien Lorber

  Hello, I use weblogic 10. Its provide an Oracle JDBC driver 10.2.0.2 (in the server/lib on weblogic home). Actually someone at work put a long time ago a 10.2.0.3 driver in instance libext folder. But in production we got a jdbc driver stack (nullpointer :O) and by reverse engineering it seems we are using driver 10.2.0.2. We know that we could change the driver in the server/lib of weblogic but i want to understand. Isn't libext supposed to override server libs like META-INF libs override libext? By the way we are in a strange situation: - We have 2 EAR, and for the exact same treatment in those 2, one will sometime throw the oracle driver nullpointer while the other doesn't - I wonder if one ear isn't using 10.2.0.2 while the other is using 10.2.0.3 (i saw a bug fixed that could fit to our problem for this version). - I need to look better but at first sight both ear use the exact same datasource set in weblogic JNDI resources Any idea?

• Where is a Web Development Career fueled by Passion? [closed]

  - by JMC Creative

  Quick Background Since learning basic html 5 years ago, I've become completely obsessed with the technology, the logic, and the thrill of solving problems involved with building websites. I am still stuck at a thoroughly non-programming type job, but would really like to move into the field of web programming/design. I have no educational background in the field (was trained as a fine artist and tutor), but in the past few years have progressed fully self-taught (and self-motivated) from html to css to php, mysql, jquery, and am now building rich web applications. The Question How can I prove to a company that even though I have no education, I have a passion to learn whatever is thrown my way? ...That essentially I would come at every issue with not only knowledge, but with a passionate desire to solve it, whether that means tackling a new language or debugging code for hours at a time? p.s. Sorry for the stupid title.

• In .NET which loop runs faster for or foreach

  - by Binoj Antony

  In c#/VB.NET/.NET which loop runs faster for or foreach? Ever since I read that for loop works faster than foreach a long time ago I assumed it stood true for all collections, generic collection all arrays etc. I scoured google and found few articles but most of them are inconclusive (read comments on the articles) and open ended. What would be ideal is to have each scenarios listed and the best solution for the same e.g: (just example of how it should be) for iterating an array of 1000+ strings - for is better than foreach for iterating over IList (non generic) strings - foreach is better than for Few references found on the web for the same: Original grand old article by Emmanuel Schanzer CodeProject FOREACH Vs. FOR Blog - To foreach or not to foreach that is the question asp.net forum - NET 1.1 C# for vs foreach [Edit] Apart from the readability aspect of it I am really interested in facts and figures, there are applications where the last mile of performance optimization squeezed do matter.

• Find java classes implementing an interface

  - by Linor

  Some time ago, I came across a piece of code, that used some piece of standard java functionality to locate the classes that implemented a given interface. I know the the functions were hidden in some non logical place, but they could be used for other classes as the package name implied. Back then I did not need it, so I forgot about it, but now I do, and I can't seem to find the functions again. Does anyone know where to find these functions? edit: I'm not looking for any IDE functions or anything, but rather something that can be executed within the java application.

• Can I automatically overwrite repository files using svn_load_dirs.pl or similiar?

  - by Andy Strang

  I am working with a legacy VSS repository which was transferred over to a new SVN repository a few months ago. In the meantime, before we go live with the SVN repository, we need to bring over all the changes that have happened on the VSS one between then and now. I was looking at different ways to do this which seem to be things such as: 1.) svn_load_dirs.pl then merge the files manually? 2.) svn import straight into the trunk and merge files manually 3.) checkout a working copy of my SVN repository, copy in the changed files which will overwrite some of the ones in my working copy then commit the changes. My question is, can any of these options be used (or any other options) to automate things so that I don't have to merge the files, and can instead just overwrite them? I think only Option 3 would do this but any help is appreciated.

• Apple Push Notification Feedback Service - how frequently does it check

  - by gem

  I have been able to successfully create push notifications and I have also received responses from the feedback service, so I am confident that my configuration is correct, but I was wondering, how long after a device has been made inactive, will it be picked up by the Apple Push Notification Service. When I first polled the feedback service, I received details on devices which were inactive several days ago. Now, while testing, when I uninstall the application and occasionally poll the feedback service, I'm not receiving any results. Any idea on how long it takes to update would be useful, as I'm no longer sure if the issue is else where in my code or if I'm just testing too soon. Thanks in advance

• typedef declaration syntax

  - by mt_serg

  Some days ago I looked at boost sources and found interesting typedef. There is a code from "boost\detail\none_t.hpp": namespace boost { namespace detail { struct none_helper{}; typedef int none_helper::*none_t ; } // namespace detail } // namespace boost I didn't see syntax like that earlier and can't explain the sense of that. This typedef introduces name "none_t" as pointer to int in boost::detail namespace. What the syntax is? And what difference between "typedef int none_helper::*none_t" and for example "typedef int *none_t" ?

• Possible Google Analytics Bug - Traffic Sources Total Visits not matching Total Visits in other repo

  - by SBAStats

  Hello, Has anyone else seen this issue? As of roughly 2 weeks ago, I get conflicting figures for the Total Visits metric between the Traffic Sources report and the other reports (e.g. Visitors, Dashboard). For example, for the week of 5/9/2010 through 5/15/2010, the Dashboard and Visitors reports both say 386 Visits. The Traffic Sources report says 157 Visits, and the 4 main source types (Search, Direct, Referral, Other) sum to 157 Visits, not 386. Any ideas? Is this a known bug, or could there be a configuration issue? Thanks.

• Is it me or is developing web based data entry GUIs a big pain?

  - by GregH

  Maybe it's me or maybe it isn't. I don't have a huge amount of experience of developing web based data entry software but do have some. I used to do it quite a bit years ago. Used to use Oracle Forms, Visual Studio, various 4th generation languages, and performing the user interface layout used to be a snap. Now doing the user interface for developing web applications seems to be a huge pain in the rear. Just trying to get text entry fields and widgets to go where they are supposed to go on the screen is a total pain. You have to know Javascript, CSS, JQuery, HTML, etc. There must be an easier way to develop data entry forms that produce the needed underlying code for a web page. Maybe I'm just not looking in the right place. There must be some WYSIWYG GUI development tools for the web for developing data entry forms out there. Anybody know of any?

• Is there a shorthand version of HTML available?

  - by monguin

  I remember reading an article about a shorthand version, or extension, of HTML a few months ago. Its purpose was to make HTML code significantly more concise, by removing end tags, and it may have allowed loops of some sort as well. I want to use it now, but I can't seem to remember what it was called. Searching online, I found HAML, but HAML syntax doesn't look like the example that I remember from the article. The syntax from the article made use of right angle brackets, which were a sort of replacement for indentation. Can anyone identify this language?

• Replacing TCP/IP pipe with WCF

  - by msarchet

  So currently my company is using a TCP/IP connection to talk between server and client programs, right now we are building this connection using System.RunTime.Remoting, which is clunky and not that reliable. It was built about 5 years ago and the model keeps getting reused and it's starting to propagate some issues, ports used, refused connections, etc. I'm trying to find some resources on how to change this over to WCF but I'm not really sure what I am looking for or what I should be searching. If you want some more information on what were actually doing with it I can go into some detail, but I'll need to pull up the code and make sure I explain it completely. thanks!

• PHP Framework Benefits / Downfalls

  - by Lizard

  I have been a PHP developer for about 10 years now and until about a month ago I have never used a framework. The framework I am now using due to an existing codebase is cakePHP 1.2 I can see certain benefits of the frameworks with the basic helpers like default layouts. I can deffinately seen the benefits of MVC keeping the logic sperate etc. But the query building just seems to be bloated. Is this expected? Am I likely to be able to build better queries than the framework could build? I just feel I could get my apps running better without a framework. What are your thoughts?

• Should I auto-increment the assembly version when I build my software?

  - by rwmnau

  In Visual Studio 2003, you could easily set your project assembly to auto-increment every time you built it, but with Visual Studio 2005, this functionality was removed. You can still auto-increment your assembly version on every build, but it's a complicated custom build step instead of an integrated feature. I'm not sure why this was removed, but here's a question I should have asked a while ago - Should I be using a workaround to continue to auto-increment when I build, or is there a good reason to stop doing this, in favor of manually incrementing? Since Microsoft removed it from VS, perhaps there's a good reason, and I'm wondering if anybody knows it.

• Why does it not allowed to use try-catch statement without {} ?

  - by alex

  Why can't I use code like this ? 1 int i = 0; try i = int.Parse("qwerty"); catch throw; 2 try i = int.Parse("qwerty"); catch; finally Log.Write("error"); And should write like this 1 int i = 0; try { i = int.Parse("qwerty"); } catch { throw; } 2 try { i = int.Parse("qwerty");} catch {} finally {Log.Write("error");} PS: I can use if-else statement without {}. Why should I use them with try-catch(-finally) statement ? Is there any meaningful reason ? Is it only because that some people think that code is hard to read ? Several months ago I asked that question on russian programming forum but I got no satisfactory answer ...
