• Return different siteMapNodes for different roles

  - by abatishchev

  I'm using my own SiteMapProvider which is just inherited and little bit rewritten System.Web.XmlSiteMapProvider. I want to return different siteMapNode for clients and for managers. Or maybe the same but with different Title property. Is it possible? If yes, how can I do that?

• auto_increment in MySQL - can I omit it?

  - by kees-kist

  I've noticed that PHPmyAdmin creates the following SQL for table creation: CREATE TABLE something ( ... ) auto_increment=1; When I write a database creation script I don't use the auto_increment bit. From reading related questions here I understand that it determines the starting value for auto_increment values. But it is good practice to reset it to 1, or should I just leave it out of the SQL so that the default is used?

• List of valid characters for the fragment identifier in an URL?

  - by sohtimsso1970

  I'm using the fragment identifier to create a permalink for AJAX events in my web app similar to this guy. Something like: http://www.myapp.com/calendar#filter:year/2010/month/5 I've done quite a bit of searching but can't find a list of valid characters for the fragment idenitifer. The W3C spec doesn't offer anything. Do I need to encode the characters the same as the URL in has in general? There doesn't seem to be any good information on this anywhere.

• C precision of double: compiler dependent?

  - by yCalleecharan

  Hi,on my 32-bit machine (with an Intel T7700 duo core), I have 15 precision digits for both double and long double types for the C language. I compared the parameters LDBL_DIG for long doubles and DBL_DIG for doubles and they are both 15. I got these answers using MVS2008. I was wondering if these results can be compiler dependent or do they just depend on my processor? Thanks a lot...

• What is the fastest way to calculate the number of bits needed to store a number

  - by Matt Wamboldt

  I'm trying to optimize some bit packing and unpacking routines. In order to do the packing I need to calculate the number of bits needed to store integer values. Here is the current code. if (n == -1) return 32; if (n == 0) return 1; int r = 0; while (n) { ++r; n >>= 1; } return r;

• How to stop htaccess rewrite rule carrying over query string

  - by geoffs3310

  I am setting up some redirects. I want to redirect the following URL: /cms/index.php?cat_id=2 to the following URL: /flash-chromatography The rule I currently have is as follows: RewriteCond %{QUERY_STRING} ^cat_id=2$ [NC] RewriteRule ^cms/index\.php$ /flash-chromatography [L,R=301] This rule is almost perfect apart from it redirect the URL to the following: /flash-chromatography?cat_id=2 So you see my problem is it has kept the ?cat_id=2 part when I don't want it to. How do I stop it keeping this bit?

• Autocomplete server-side implementation

  - by toluju

  What is a fast and efficient way to implement the server-side component for an autocomplete feature in an html input box? I am writing a service to autocomplete user queries in our web interface's main search box, and the completions are displayed in an ajax-powered dropdown. The data we are running queries against is simply a large table of concepts our system knows about, which matches roughly with the set of wikipedia page titles. For this service obviously speed is of utmost importance, as responsiveness of the web page is important to the user experience. The current implementation simply loads all concepts into memory in a sorted set, and performs a simple log(n) lookup on a user keystroke. The tailset is then used to provide additional matches beyond the closest match. The problem with this solution is that it does not scale. It currently is running up against the VM heap space limit (I've set -Xmx2g, which is about the most we can push on our 32 bit machines), and this prevents us from expanding our concept table or adding more functionality. Switching to 64-bit VMs on machines with more memory isn't an immediate option. I've been hesitant to start working on a disk-based solution as I am concerned that disk seek time will kill performance. Are there possible solutions that will let me scale better, either entirely in memory or with some fast disk-backed implementations? Edits: @Gandalf: For our use case it is important the the autocompletion is comprehensive and isn't just extra help for the user. As for what we are completing, it is a list of concept-type pairs. For example, possible entries are [("Microsoft", "Software Company"), ("Jeff Atwood", "Programmer"), ("StackOverflow.com", "Website")]. We are using Lucene for the full search once a user selects an item from the autocomplete list, but I am not yet sure Lucene would work well for the autocomplete itself. @Glen: No databases are being used here. When I'm talking about a table I just mean the structured representation of my data. @Jason Day: My original implementation to this problem was to use a Trie, but the memory bloat with that was actually worse than the sorted set due to needing a large number of object references. I'll read on the ternary search trees to see if it could be of use.

• Build farms using ccnet

  - by Grzenio

  Is it possible to use CruiseControl.Net to set up a build farm? We currently have 4 different build machines building different things at different times and have a bit of a headache to manually balance the load somehow. I would prefer to designate one of them to be the master build machine, which would delegate work to the other ones when they are free.

• Is ZendX still active (Specifically ZendX_JQuery) ?

  - by Doron

  I need to have an autocomplete functionality using jquery, and I've encountered ZendX_JQuery which has such functionality available. However, I've noticed that the entire ZendX_JQuery classes, are a bit old (the default jquery version is 1.3.2, and jquery ui 1.7.1). (see http://framework.zend.com/svn/framework/extras/branches/release-1.10/library/ZendX/JQuery.php) Should I use that instead of my own written code to include the jquery library and etc., and should I use the ZendX_JQuery_View_Helper_AutoComplete class for such functionality ?

• Python: Script works, but seems to deadlock after some time

  - by sberry2A

  I have the following script, which is working for the most part Link to PasteBin The script's job is to start a number of threads which in turn each start a subprocess with Popen. The output from each subprocess is as follows: 1 2 3 . . . n Done Bascially the subprocess is transferring 10M records from tables in one database to different tables in another db with a lot of data massaging/manipulation in between because of the different schemas. If the subprocess fails at any time in it's execution (bad records, duplicate primary keys, etc), or it completes successfully, it will output "Done\n". If there are no more records to select against for transfer then it will output "NO DATA\n" My intent was to create my script "tableTransfer.py" which would spawn a number of these processes, read their output, and in turn output information such as number of updates completed, time remaining, time elapsed, and number of transfers per second. I started running the process last night and checked in this morning to see it had deadlocked. There were not subprocceses running, there are still records to be updated, and the script had not exited. It was simply sitting there, no longer outputting the current information because no subprocces were running to update the total number complete which is what controls updates to the output. This is running on OS X. I am looking for three things: I would like to get rid of the possibility of this deadlock occurring so I don't need to check in on it as frequently. Is there some issue with locking? Am I doing this in a bad way (gThreading variable to control looping of spawning additional thread... etc.) I would appreciate some suggestions for improving my overall methodology. How should I handle ctrl-c exit? Right now I need to kill the process, but assume I should be able to use the signal module or other to catch the signal and kill the threads, is that right? I am not sure whether I should be pasting my entire script here, since I usually just paste snippets. Let me know if I should paste it here as well.

• C++ Win32 API equivalent of CultureInfo.TwoLetterISOLanguageName

  - by Brian Gillespie

  The .NET framework makes it easy to get information about various locales; the Win32 C++ APIs are a bit harder to figure out. Is there an equivalent function in Win32 to get the two-letter ISO language name given an integer locale ID? In C# I'd do: System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo(1034); string iso = ci.TwoLetterISOLanguageName; // iso == "es" now.

• Passing array into constructor to use on JList

  - by OVERTONE

  I know the title sound confusing and thats because it is. its a bit long so try too stay with me. this is the layout i have my code designed variables constructor methods. im trying too fill a Jlist full on names. i want too get those names using a method. so here goes. in my variables i have my JList. its called contactNames; i also have an array which stores 5 strings which are the contacts names; heres the code for that anyway String contact1; String contact2; String contact3; String contact4; String contact5; String[] contactListNames; JList contactList; simple enough. then in my constructor i have the Jlist defined to fill itself with the contents of the array fillContactList(); JList contactList = new JList(contactListNames); that method fillContactList() is coming up shortly. notice i dont have the array defined in the constructor. so heres my first question. can i do that? define the array to contain something in te constructor rather than filling it fromt the array. now heres where stuff gets balls up. ive created three different methods all of which havent worked. basically im trying to fill the array with all of them. this is the simplest one. it doesnt set the Jlist, it doesnt do anything compilicated. all it trys too do is fill the array one bit at a time public void fillContactList() { for(int i = 0;i<3;i++) { try { String contact; System.out.println(" please fill the list at index "+ i); Scanner in = new Scanner(System.in); contact = in.next(); contactListNames[i] = contact; in.nextLine(); } catch(Exception e) { e.printStackTrace(); } } } unfortunately this doesnt qwork. i get the print out to fill it at index 0; i input something and i get a nice big stack trace starting at contactListNames[i] = contact; so my two questions in short are how i define an array in a constructor. and why cant i fill the array from that method. ************************888 **************************888 stack trace by request please fill the list at index 0 overtone java.lang.NullPointerException please fill the list at index 1 at project.AdminMessages.fillContactList(AdminMessages.java:408) at project.AdminMessages.<init>(AdminMessages.java:88) at project.AdminUser.createAdminMessages(AdminUser.java:32) at project.AdminUser.<init>(AdminUser.java:18) at project.AdminUser.main(AdminUser.java:47) it was a null poiinter exception

• Ruby on rails authlogic config (get rid of capitalization check)

  - by bandhunt

  The authlogic rails gem is doing a LOWER in the sql query. SELECT * FROM `users` WHERE (LOWER(`users`.email) = '[email protected]') LIMIT 1 I want to get rid of the LOWER part since it seems to be slowing down the query by quite a bit. I'd prefer to just lower the case in the code since this query seems to be expensive. I'm not sure where to change this behavior in authlogic. Thanks!

• Visual Studio 2010 -- how to reduce its memory footprint

  - by GregC

  I have a solution with just under 100 projects in it, a mix of C++ and C# (mostly C#). When working in VS2005, the working set of Visual Studio is considerably smaller than that of VS2010. I was wondering if there are some things that can be turned off, so I can develop in VS2010 under 32-bit OS without running out of memory.

• Future proof Tweeting with PHP

  - by YsoL8

  Hello I'm looking to implement a system for tweeting directly from my site backend, which is written in PHP 5. I have a script from the internet that I can adapt, but I'm concerned that when Twitter switches to Oauth only, I'll be out in the cold. Basically, I'm hoping someone can point me toward a script/tutorial that will let me do the following: access twitter via the Oauth system Post Tweets and receive error codes Let me define an application/site name (I'm a bit fuzzy on whether Twitter allows this) Ideally I need all 3 points explained in detail. Thanks

• Change/Update a pane using python wx.AUI

  - by Dan

  I'm using wx.AUI and having a bit of a problem managing panes. Once you have created a new pane using AddPane(), what is the syntax to update or change the pane? I've seen the SetPane command but I can't find any examples. Can someone direct me to an example? Or perhaps it makes sense to use some command to delete the pane and create a new one? Thanks in advance for your time.
