• Can a 32-bit RHEL4 userland work with a 64-bit kernel?

  - by James

  Is there a way to change an i386 RHEL4 machine to run an amd64 kernel, but ensure that it still builds software into same i386 binaries? On Debian this seems quite straightforward: just install an amd64 kernel (worst case, build one like this guy: http://www.debian-administration.org/users/jonesy/weblog/1) and prefix everything with "linux32". Then everything that considers uname -m will be unchanged, I just need to handle the few cases that consider uname -r. What is the Red Hat equivalent? Is the only way a full 64-bit installation on another disk and then chrooting back to the 32-bit system before anyone builds anything? (Even the best examples of that seem to be Debian-based.) Background: We make a large system that runs on (a variant of) i386 RHEL4. However, some of the larger RHEL build machines now have enough RAM that they might benefit from going 64-bit (for the kernel and maybe some of the bigger build steps). Our build system doesn't support cross-compilation.

• Is there any sense in performing binary AND with a number where all bits are set to 1

  - by n535

  Greetings everybody. I have seen examples of such operations for so many times that I begin to think that I am getting something wrong with binary arithmetic. Is there any sense to perform the following: byte value = someAnotherByteValue & 0xFF; I don't really understand this, because it does not change anything anyway. Thanks for help. P.S. I was trying to search for information both elsewhere and here, but unsuccessfully. EDIT: Well, off course i assume that someAnotherByteValue is 8 bits long, the problem is that i don't get why so many people ( i mean professionals ) use such things in their code. For example in Jon Skeet's MiscUtil there is: uint s1 = (uint)(initial & 0xffff); where initial is int.

• SharePoint filtered column that only allows item to be used once

  - by Jason

  I have a WSS 3.0 site that I use for change management. There are three primary lists on it -- a bug list, an enhancement list, and a release list. The release list has two lookup columns that provide a list of bugs and enhancements that are included in that particular release. I am trying to figure out how to filter the bug and enhancement list to include only items that have not already been included in another release. All the docs and examples I have seen regarding filtered lookups deal with a query on the list itself. For my situation, and if this was a SQL query, I would need to use a LEFT JOIN to generate the list.

• Steps in subclassing UINavigationController

  - by RickiG

  Hello I would like to subclass the UINavigationController to get some more freedom in regards to the appearance of the controller. I have some graphics for the different parts, bars, buttons, text etc. Looking at the UINavigationController header file I get little help, I don't know where to start out. I have never subclassed/overridden a UIKit component before, it seems it is a bit like playing Sherlock Holmes. What is the approach? How do I know what to override to get a a specific piece of graphics "injected" the correct place? Do I need to subclass UINavigationBar, UIBarButtonItem etc. etc to get the complete customized look? How do I know if something is off limits in regards to being approved by Apple? Hope someone can point me in the right direction, I have only been able to find examples of changing small parts of the controller, not a full customization by subclassing. Am I going about this the wrong way? Thanks:)

• Facebook - using an external flash application to connect via PHP

  - by Anonymous

  So, I have this application that needs to connect to facebook. It uses php for all of its data access, in older examples of the facebook API, i see people get the UID, and sessionkey from the iframe page, then send them to php and run a function called $facebook-setUser($UID, $sessionKey). This is how the majority of the tutorials online are doing it. That would be great, except the newest facebook API doesn't have any function like that. I have been scouring the web for 2 hours and have found nothing relating to the disappearance of this seemingly critical function. So, I have a flash application that needs to authenticate via a stateless php resource. I would love it if my PHP code could be completely uncaring if the request originated from flash, or iphone, or another application altogether-it should just need userId and and sessionKey. Is this still possible? Thank you in advance for your help! :)

• How to engineer features for machine learning

  - by Ivo Danihelka

  Do you have some advices or reading how to engineer features for a machine learning task? Good input features are important even for a neural network. The chosen features will affect the needed number of hidden neurons and the needed number of training examples. The following is an example problem, but I'm interested in feature engineering in general. A motivation example: What would be a good input when looking at a puzzle (e.g., 15-puzzle or Sokoban)? Would it be possible to recognize which of two states is closer to the goal?

• - Default value of variables at the time of declaration -

  - by gotye

  Hey guys, I was wondering what was the default values of variables before I intialize them .. For example, if I do : //myClass.h BOOL myBOOL; // default value ? NSArray *myArray; // default value ? NSUInteger myInteger; // default value ? Some more examples here : //myClass.m // myArray is not initialized, only declared in .h file if ([myArray count] == 0) { // TRUE or FALSE ? // do whatever } More generally, what is returned when I do : [myObjectOnlyDeclaredAndNotInitialized myCustomFunction]; Thank you for your answers.

• C functions invoked as threads - Linux userland program

  - by Einar

  I'm writing a linux daemon in C which gets values from an ADC by SPI interface (ioctl). The SPI (spidev - userland) seems to be a bit unstable and freezes the daemon at random times. I need to have some better control of the calls to the functions getting the values, and I was thinking of making it as a thread which I could wait for to finish and get the return value and if it times out assume that it froze and kill it without this new thread taking down the daemon itself. Also I could do other things like resetting the ADC before restarting. Is this possible? Pseudo example of what I want to achieve: (function int get_adc_value(int adc_channel, float *value) ) pid = thread( get_adc_value(1,&value); //makes thread wait_until_finish(pid, timeout); //waits until function finishes/timesout if(timeout) kill pid, start over //if thread do not return in given time, kill it (it is frozen) else if return value sane, continue //if successful, handle return variable value and continue Thanks for any input on the matter, examples highly appreciated!

• Websites with horizontal accordion effect

  - by peterdp

  Hi Folks, I was delighted with the responses folks offered to the question about horizontal sliding panels that I thought I would try again. In subsequent discussions with my colleagues, it became clearer that we would also like to consider horizontal accordion effects, so I am looking for some concrete, real world examples. Soo... I would once again be most grateful to the stalwart StackOverflowians who could take a moment to paste links to their favorite website(s) that use a horizontal accordion effect well. Extra kudos if you can promote your own site! Thanks so very much if you can help!

• JQuery-tmpl Template Switching Not working.

  - by Mike

  I'm trying to implement "more/less" functionality using the official jquery-tmpl plugin. I've looked at the examples, but I cannot seem to get the functionality to work in my own implementation. When I click on one of my "More" buttons, I seem to get an error thrown of: Uncaught TypeError: Property 'tmpl' of object #<an Object> is not a function This is my implementation here From what I can tell, the example I'm trying to replace is doing the following: Render the "Master" template On-click: Find the corresponding template object (tmplItem) to the clicked element. Pass in reference to a new template. Call the update function to re-render. Have I understood the documentation wrong? From what I can tell I'm doing the same thing as the example on the official documentation.

• Object does not support this propery or method IE & jQuery

  - by Mirko

  I am using jQuery and the cornerz plug in to get rounded corners on elements of the page without using images. In IE7 and 8 it fails and I get this error: "Object doesn't support this property or method" on this lines: if($.browser.msie && settings.fixIE) { var ow = $$.outerWidth(); var oh = $$.outerHeight(); Basically it complains about the outerWidth and outerHeight properties... The cornerz demo page (here) works perfectly on IE7 and 8 without throwing any error and it has got several examples...I do not know why this is happening Any suggestion will be appreciated Thanks in advance

• How to retrieve email from GMail account using PHP?

  - by Tatu Ulmanen

  Hi, I'm trying to automatically retrieve some email from my GMail account for further parsing, but I can't get my head around on how to do that. I've searched the internets and it suggested that I use PHP's imap functions, like this: $server = '{imap.gmail.com:993/ssl}'; $connection = imap_open($server, '[email protected]', 'password'); But using that code, I get: Warning: imap_open() [function.imap-open]: Couldn't open stream {imap.gmail.com:993/ssl} Any idea what I am doing wrong? Any server setting that might be preventing me from making a connection to GMail (I'm using a shared service)? Is the address even right? Has anyone ever managed to do something like this? I've found tons of examples on how to send email via GMail, but very little of retrieving. Any help is much appreciated.

• Magento Flash + XML frontend

  - by Nick Dima

  Hi guys, I'm working on a Flash frontend for a Magento powered store. This frontend will be an alternative to the HTML shop so it will sit in a subdirectory and use the same Magento installation as the main HTML site. The Flash application will get the data from dynamic XML files. It needs to get almost everything as the HTML site (categories, products, cart, etc). I want this to be a Magento module that can be installed on an already existing Magento installation. I would like to use the Block classes available in Magneto's core code as they already provide a lot of the functionality needed. What steps would you take in order to achieve this? Do you know any examples or articles related to this? Thanks!

• Reading HttpURLConnection InputStream - manual buffer or BufferedInputStream?

  - by stormin986

  When reading the InputStream of an HttpURLConnection, is there any reason to use one of the following over the other? I've seen both used in examples. Manual Buffer: while ((length = inputStream.read(buffer)) > 0) { os.write(buf, 0, ret); } BufferedInputStream is = http.getInputStream(); bis = new BufferedInputStream(is); ByteArrayBuffer baf = new ByteArrayBuffer(50); int current = 0; while ((current = bis.read()) != -1) { baf.append(current); } EDIT I'm still new to HTTP in general but one consideration that comes to mind is that if I am using a persistent HTTP connection, I can't just read until the input stream is empty right? In that case, wouldn't I need to read the message length and just read the input stream for that length? And similarly, if NOT using a persistent connection, is the code I included 100% good to go in terms of reading the stream properly?

• How to deal with databases for websites written in Java, more specifically Wicket?

  - by John

  Hi there. I'm new to website development using Java but I've got started with Wicket and make a little website. I'd like to expand on what I've already made (a website with a form, labels and links) and implement database connectivity. I've looked at a couple of examples, in example Mystic Paste, and I see that they're using Hibernate and Spring. I've never touched Hibernate or Spring before and to be honest the heavy use of annotations scare me a little bit as I haven't really made use of them before, with the exception of supressing warnings and overriding. At this point I have one Connection object which I set up in the WebApplication class upon initialization. I then retrieve this connection object whenever I need to perform queries. I don't know if this is a bad approach or not for a production web application. All help is greatly appreciated.

• Unit testing a SQL code generator

  - by Tom H.

  The team I'm on is currently writing code in TSQL to generate TSQL code that will be saved as scripts and later run. We're having a little difficulty in separating our unit tests between testing the code generator parts and testing the actual code that they generate. I've read through another similar question, but I was hoping to get some specific examples of what kind of unit test cases we might have. As an example, let's say that I have a bit of code that simply generates a DROP statement for a view, given the view schema and name. Do I just test that the generated code matches some expected outcome using string comparisons and then in a later integration or system test make sure that the drop actually drops the view if it exists, does nothing if the view doesn't exist, or raises an error if the view is one that we are marking as not allowing a drop? Thanks for any advice!

• Overwrite Content in PHP fwrite()

  Is there any way you can overwrite a line in PHP. let me be a little more clearer using examples. My array array{ [DEVICE] => eth0, [IPADDR] => 192.168.0.2, [NETMASK] => 255.255.255.0, [NETWORK] => 192.168.0.0, [BROADCAST] => 255.255.255.255, [GATEWAY] => 192.168.0.1, [ONBOOT] => no } File im overwriting DEVICE=eth0 IPADDR=192.168.200.2 NETMASK=255.255.255.0 NETWORK=192.168.200.0 BROADCAST=255.255.255.255 GATEWAY=192.168.200.1 ONBOOT=no DNS1=195.100.10.1 Result of the File that is rewritten DEVICE=eth0 IPADDR=192.168.0.2 NETMASK=255.255.255.0 NETWORK=192.168.0.0 BROADCAST=255.255.255.255 GATEWAY=192.168.0.1 ONBOOT=no DNS1=195.100.10.1 Note that DNS1=195.100.10.1 Stays in the file becuase it dosent have a key with the value of DNS in our array.

• PDF text search and split library

  - by Horace Ho

  I am look for a server side PDF library (or command line tool) which can: split a multi-page PDF file into individual PDF files, based on a search result of the PDF file content Examples: Search "Page ???" pattern in text and split the big PDF into 001.pdf, 002,pdf, ... ???.pdf A server program will scan the PDF, look for the search pattern, save the page(s) which match the patten, and save the file in the disk. It will be nice with integration with PHP / Ruby. Command line tool is also acceptable. It will be a server side (linux or win32) batch processing tool. GUI/login is not supported. i18n support will be nice but no required. Thanks~

• "The C Programming Language" interesting quote in the preface

  - by kurige

  From the preface of the second edition of Kernighan and Ritchie's "The C Programming Language": As before, all examples have been tested directly from the text, which is in machine-readable form. That quote threw me for a loop. What exactly does it mean? Was the original manuscript written as a literate program? My first thought was that this book, published in 1988 (original, first edition in 1978) predates literate programming, but now I'm not so sure. Can anybody shed some light on this?

• Project design / FS layout for large django projects

  - by rcreswick

  What is the best way to layout a large django project? The tutuorials provide simple instructions for setting up apps, models, and views, but there is less information about how apps and projects should be broken down, how much sharing is allowable/necessary between apps in a typical project (obviously that is largely dependent on the project) and how/where general templates should be kept. Does anyone have examples, suggestions, and explanations as to why a certain project layout is better than another? I am particularly interested in the incorporation of large numbers of unit tests (2-5x the size of the actual code base) and string externalization / templates.

• Ethics of assisting other programmers, where do we draw the line?

  - by Chris

  In general, not just in relation to stackoverflow, sometimes I'm asked a programming question for which the answer will probably be used for good purposes, but there is a chance that it could not be. Two recent examples which reminded me of some real world questions I've been asked are: Send email to many users, and keep a formless application from closing for a keyboard hook Though I don't believe the intent of the authors of those questions is in any way nefarious, occasionally someone does ask such a question for purposes of aiding a spamming effort, or creating a keylogger. Even though the questioner and answerers had good intent, a 3rd party could pervert those answers to create a piece of malware or a spam utility. Should we always trust the questioner to use the answer for good? Should we feel obligated to ask the purpose of a question, and how the answer will be used? And how can we prevent answers from being overheard (when asked verbally) or being referenced (when posted publicly online) and then used for unsavory purposes?

• Using Markov models to convert all caps to mixed case and related problems

  - by hippietrail

  I've been thinking about using Markov techniques to restore missing information to natural language text. Restore mixed case to text in all caps Restore accents / diacritics to languages which should have them but have been converted to plain ASCII Convert rough phonetic transcriptions back into native alphabets That seems to be in order of least difficult to most difficult. Basically the problem is resolving ambiguities based on context. I can use Wiktionary as a dictionary and Wikipedia as a corpus using n-grams and Markov chains to resolve the ambiguities. Am I on the right track? Are there already some services, libraries, or tools for this sort of thing?

• abstract method signature, inheritance, and "Do" naming convention

  - by T. Webster

  I'm learning about design patterns and in examples of code I've seen a convention where the abstract class declares a method, for example: public abstract class ServiceBase { ... public virtual object GetSomething(); and then protected abstract object DoGetSomething(); My question is on why these two methods exist, since they appear to serve the same purpose. Is this so that the base class GetSomething() method logic cannot be overridden by inherited classes? But then again, the method is marked virtual, so it can be overridden anyway. What is the usefulness here in requiring derived class implementers to implement the abstract method when the virtual method can be called anyway?
