• Help Installing phpMyAdmin on Linux Server

  - by Joe Majewski

  I constantly get this error when attempting to view index.php in the phpMyAdmin folder I have setup: Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly. I am using subversion with three co-workers and I am trying to install this on my repository, which is at /svni3/myusername/intranet/ on our linux development server. I do have shell access so I would be able to install it somewhere else if that may be causing the problem. My config.inc.php file looks like this (only the things I changed): $cfg['blowfish_secret'] = 'blah'; $cfg['Servers'][$i]['auth_type'] = 'cookie'; //$cfg['Servers'][$i]['user'] = 'username'; //$cfg['Servers'][$i]['password'] = 'password'; $cfg['Servers'][$i]['host'] = 'localhost'; Other helpful information??? When I ping localhost it works. When I run the command "ls -l /var/lib/php": drwxrwx--- 2 root apache 4096 2009-04-17 02:31 session If there's anything else that may be helpful let me know; this has been plaguing me for a few hours now.

• Help translating from assembly to C

  - by user324994

  I have some code from a function subl $24, %esp movl 8(%ebp), %eax cmpl 12(%ebp), %eax Before the code is just the 'ENTER' command and afterwards there's an if statement to return 1 if ebp eax or 0 if it's less. I'm assuming cmpl means compare, but I can't tell what the concrete values are. Can anyone tell me what's happening?

• Please help me optimize my Python code

  - by Haidon

  Beginner here! Forgive me in advance for raising what is probably an incredibly simple problem. I've been trying to put together a Python script that runs multiple find-and-replace actions and a few similar things on a specified plain-text file. It works, but from a programming perspective I doubt it works well. How would I best go about optimizing the actions made upon the 'outtext' variable? At the moment it's basically doing a very similar thing four times over... import binascii import re import struct import sys infile = sys.argv[1] charenc = sys.argv[2] outFile=infile+'.tex' findreplace = [ ('TERM1', 'TERM2'), ('TERM3', 'TERM4'), ('TERM5', 'TERM6'), ] inF = open(infile,'rb') s=unicode(inF.read(),charenc) inF.close() # THIS IS VERY MESSY. for couple in findreplace: outtext=s.replace(couple[0],couple[1]) s=outtext for couple in findreplace: outtext=re.compile('Title: (.*)', re.I).sub(r'\\title'+ r'{\1}', s) s=outtext for couple in findreplace: outtext=re.compile('Author: (.*)', re.I).sub(r'\\author'+ r'{\1}', s) s=outtext for couple in findreplace: outtext=re.compile('Date: (.*)', re.I).sub(r'\\date'+ r'{\1}', s) s=outtext # END MESSY SECTION. outF = open(outFile,'wb') outF.write(outtext.encode('utf-8')) outF.close()

• Error using 'send_file' for ruby/rails - help appreciated

  - by user1653279

  I am trying to create a link to download a file from the file system. For this, I define the following in the "license_helper.rb" file: def license_download_link(license, link_text = nil) if link_text.blank? link_text = image_tag("download_icon.png", :border => 0, :width => 32, :height =>32, :alt => 'Download License', :title => 'Download License') end tempLicenseFile = "tempLicense.xml" File.open("#{tempLicenseFile}", 'w') do |tf| tf.puts license.data end command = "./runLicenseEncoder.bat #{tempLicenseFile}" generateEncryptedLicenseFile = `#{command}` theLicenseFile = "license.xml" link_to link_text, "license/download" end My "view" just calls this helper class: <td><%= license_download_link(license, ' ') %></td> In the 'routes.rb' file, I have defined the following: map.licensedownload "license.xml", :controller = 'licenses', :action = 'download' map.download "/licenses/download", :controller = 'licenses', :action = 'download' In the 'controller', I have 'licenses_controller.rb' which includes the following: def download theLicense = @license licenseFileName = "license.xml" send_file "#{licenseFileName}" , :type => "application/xml", :filename => "#{licenseFileName}" end However, I am unable to obtain the '@license' attribute from the database in the controller. Could someone please let me know what I am doing wrong here and why I am unable to get the value for "@license". Thanks for your time, Regards, --- AJ

  I own the domain name, iamgabeaudick.com. It was my personal website, but I now want to use it as my tumblr domain. I've changed the DNS, and tumblr confirms that the domain is set up correctly. But when I access iamgabeaudick.com, a blank "Index of /" page appears. Any ideas why this is? Do I need to configure the ftp files in some way?

• IPhone iOs 5, need help getting my tab bar at the top to work

  - by Patrick

  I wanted to have the tab bar at the top. So i created a new project in XCode. Added a view and then inside that view i added (scrollbar, text and another view). See picture. What i wanted was to have my tab bar at the top. Then in the middle would be the contents from the tab bar and below it a small copyright text. See picture. No idea how to make this correctly. I have tried to create the UITabBarController on the fly and then assign it into the view at the top. (Top white space on the picture dedicated for the tab bar). Here is my code to init the MainWindow. MainWindow.h #import <UIKit/UIKit.h> @class Intro; @interface MainWindow : UIViewController @property (strong, nonatomic) IBOutlet UIScrollView *mainContentFrame; @property (strong, nonatomic) IBOutlet UIView *mainTabBarView; @property (strong, nonatomic) UITabBarController *mainTabBar; @property (nonatomic, strong) Intro *intro; // Trying to get this tab to show in the tab bar @end MainWindow.m #import "MainWindow.h" #import "Intro.h" @interface MainWindow () @end @implementation MainWindow @synthesize mainContentFrame = _mainContentFrame; @synthesize mainTabBarView = _mainTabBarView; @synthesize mainTabBar = _mainTabBar; @synthesize intro = _intro; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { _intro = [[Intro alloc] init]; NSArray *allViews = [[NSArray alloc] initWithObjects:_intro, nil]; [super viewDidLoad]; // Do any additional setup after loading the view. _mainTabBar = [[UITabBarController alloc] init]; [_mainTabBar setViewControllers:allViews]; [_mainTabBarView.window addSubview:_mainTabBar.tabBarController.view]; } - (void)viewDidUnload { [self setMainTabBar:nil]; [self setMainContentFrame:nil]; [self setMainContentFrame:nil]; [super viewDidUnload]; // Release any retained subviews of the main view. } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait); } @end What am i missing to get this to work? Wanted the content to end up in the scrollview so that all tabs are scrollable.

• Need help/guidance about creating a desktop application with gui

  - by Somebody still uses you MS-DOS

  I'm planning to do an Desktop application using Python, to learn some Desktop concepts. I'm going to use GTK or Qt, I still haven't decided which one. Fact is: I would like to create an application with the possibility to be called from command line, AND using a GUI. So it would be useful for cmd fans, and GUI users as well. It would be interesting to create a web interface too in the future, so it could be run in a server somewhere using an html interface created with a template language. I'm thinking about two approaches: - Creating a "model" with a simple interface which is called from a desktop/web implementation; - Creating a "model" with an html interface, and embeb a browser component so I could reuse all the code in both desktop/web scenarios. My question is: which exactly concepts are involved in this project? What advantages/disadvantages each approach has? Are they possible? By naming "interface", I'm planning to just do some interfaces.py files with def calls. Is this a bad approach? I would like to know some book recommendations, or resources to both options - or source code from projects which share the same GUI/cmd/web goals I'm after. Thanks in advance!

• Need some help in understanding SSL concepts

  - by user1115256

  I am new to SSL programming and finding some difficulties in understanding SSL concepts. I tried to get it through openssl site,but it is not much informative. Here is my doubts. What is difference between SSL Buffer and BIO buffer..? I mean layerwise detail will be very helpful. Can I use SSL_Write and SSL_Read without setting any BIO object to SSL object..? What exactly BIO_flush will do... I mean is it going to flush all the data to network buffer from BIO buffer.. ? If it is possible to do write and read data from SSL directly without using any BIO object then is it possible to flush the data from SSL buffer to network buffer by any means.. ? It would be very helpful if any body explain these things or giving any links where I can find answers to my questions.

• Need Help Figuring Out Why Text Is Overflowing My Page

  - by Brian

  Like the title says, I am having issues with a VERY long string overflowing my page. I tried some overflow techniques, but none seem to work. I had previously posted this as a Primefaces problem, but have since learned that it is not a Primefaces issue. Anyway, if anybody has any suggestions on how I can fix this, I would appreciate it. I will post my HTML below so you can see what I am talking about. Thanks for taking the time to read, and have a great day. :-) <!DOCTYPE html> <html> <head> <title> problem </title> <style type="text/css"> span.troubleSpan { overflow: scroll; } </style> </head> <body> <h4> problem </h4> <div> <table border="1"> <tr> <td> <span>cell</span> </td> <td> <span>&nbsp;</span> </td> <td> <span>cell</span> </td> <td> <span class="troubleSpan">asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf</span> </td> <td> <span>&nbsp;</span> </td> </tr> </table> </div> </body> </html>

• Need help optimizing this Django aggregate query

  - by Chris Lawlor

  I have the following model class Plugin(models.Model): name = models.CharField(max_length=50) # more fields which represents a plugin that can be downloaded from my site. To track downloads, I have class Download(models.Model): plugin = models.ForiegnKey(Plugin) timestamp = models.DateTimeField(auto_now=True) So to build a view showing plugins sorted by downloads, I have the following query: # pbd is plugins by download - commented here to prevent scrolling pbd = Plugin.objects.annotate(dl_total=Count('download')).order_by('-dl_total') Which works, but is very slow. With only 1,000 plugins, the avg. response is 3.6 - 3.9 seconds (devserver with local PostgreSQL db), where a similar view with a much simpler query (sorting by plugin release date) takes 160 ms or so. I'm looking for suggestions on how to optimize this query. I'd really prefer that the query return Plugin objects (as opposed to using values) since I'm sharing the same template for the other views (Plugins by rating, Plugins by release date, etc.), so the template is expecting Plugin objects - plus I'm not sure how I would get things like the absolute_url without a reference to the plugin object. Or, is my whole approach doomed to failure? Is there a better way to track downloads? I ultimately want to provide users some nice download statistics for the plugins they've uploaded - like downloads per day/week/month. Will I have to calculate and cache Downloads at some point? EDIT: In my test dataset, there are somewhere between 10-20 Download instances per Plugin - in production I expect this number would be much higher for many of the plugins.

• Help for creating a random String

  I need to create a random string which should be between the length of 6 to 10 but it sometimes generates only about the length of 3 to 5. Here's my code. Can anyone would be able to find out the problem? :( int lengthOfName = (int)(Math.random() * 4) + 6; String name = ""; /* randomly choosing a name*/ for (int j = 0; j <= lengthOfName; j++) { int freq = (int)(Math.random() * 100) + 1; if(freq <= 6){ name += "a"; }if(freq == 7 && freq == 8){ name += "b"; }if(freq >= 9 && freq <= 11){ name += "c"; }if(freq >= 12 && freq <= 15){ name += "d"; }if(freq >= 16 && freq <= 25){ name += "e"; }if(freq == 26 && freq == 27){ name += "f"; }if(freq == 28 && freq == 29){ name += "g"; }if(freq >= 30 && freq <= 33){ name += "h"; }if(freq >= 34 && freq <= 48){ name += "i"; }if(freq == 49 && freq == 50){ name += "j"; }if(freq >= 51 && freq <= 55){ name += "k"; }if(freq >= 56 && freq <= 60){ name += "l"; }if(freq == 61 && freq == 62){ name += "m"; }if(freq >= 63 && freq <= 70){ name += "n"; }if(freq >= 71 && freq <= 75){ name += "o"; }if(freq == 76 && freq == 77){ name += "p"; }if(freq == 78){ name += "q"; }if(freq >= 79 && freq <= 84){ name += "r"; }if(freq == 85 && freq == 86){ name += "s"; }if(freq == 87 && freq == 88){ name += "t"; }if(freq >= 89 && freq <= 93){ name += "u"; }if(freq == 94){ name += "v"; }if(freq == 95 && freq == 96){ name += "w"; }if(freq == 97){ name += "x"; }if(freq == 98 && freq == 99){ name += "y"; }if(freq == 100){ name += "z"; } }

• Need help on how to setup package structure and project

  - by jax

  I am new to Java and am making a license generator. This is my current setup. com.example.licensegenerator.client (used by the client application) :LicenseLoader (no Main method) :LicenseDownloader (no Main method) com.example.licensegenerator.server.keys (used by the server) :ProductKeyGenerator(Main method) com.example.licensegenerator.server.license (used on the server also) :LicenseGenerator(Main method) com.example.licensegenerator.lib (Shared classes between client and server) :Contants (no main) Now I have a few questions. Is it OK to have multiple Main() methods in a single project? Will I be able to compile them to different .jar files? (In this case I need two different jars for the server) Is there a better way to setup the packages? And a totally unrelated question, with exceptions, is it better to handle them right then and there or throw them and let the main method catch them all (the program cannot recover if an error occurs)

• Help choosing the right data structure

  - by devoured elysium

  I need a data structure with the following requirements: Needs to be able to get elements by index (like a List). I will always just add / remove elements from the end of the structure. I am inclined to use an ArrayList. In this situation, it seems to be O(1) both to read elements (they always are?), remove elements (I only need to remove them at the end of the list) and to add(I only add to the end of the list). There is only the problem that time to time the ArrayList will have a performance penalty when it's completly full and I need to add more elements to it. Is there any other better idea? I don't think of a data structure that'd beat the ArrayList here. Thanks

• Help adding a backgroundView to UITableViewCell

  - by Alex

  I'm getting really desperate trying to add a UIImageView to UITableViewCell.backgroundView. All my efforts have resulted in this crappy rendering: It looks like the cell's label's white background is sitting on top of cell's background and covering portions of it. I tried setting the label's background color to clear, or some other color and it does not have any event. It is always white. The reason I know it's the text label's background causing this white area is that if I don't do [cell setText:@"Cell text here"]; the white area is gone and I see just the cell's background image. Here's the code that I'm using. The table view is added in the .xib file and UITableView is added to UIViewController: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [myCollection.items count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSUInteger rowIndex = indexPath.row; static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"darkCellBackground.png"]]; cell.selectedBackgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"darkCellBackground.png"]]; } [cell setText:@"Cell text here"]; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; // [self.navigationController pushViewController:anotherViewController]; // [anotherViewController release]; [tableView deselectRowAtIndexPath:indexPath animated:YES]; } - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { return NO; } I'm sure I'm doing something wrong but cant quite figure out what.

• Help with doctype issues

  Hi I am having issues making my footer stick to the bottom of the page in all browsers. I have the following document structure: <html> <head> </head> <body> <div id="wrapper"> <div id="header"> <ul> <li>home</li> </ul> </div> <div class="expander"></div> </div> <div id="footer" class="expander"> </div> </body> </html> Relevant CSS is: body { margin: 0; height: 100%; } #wrapper { min-height: 100%; height: auto !important; height: 100%; margin: 0 auto -116px; } .expander { height: 116px; } #footer { width: 100%; } #header ul { list-style: none outside none; clear: both; margin: 0; } #header li { margin: 0; margin-right: 20px; padding: 0; display: inline-block; height: 85px; padding-top: 20px; margin-bottom: -20px; } When used without any doc type, the page renders as I intend it to in Chrome and Firefox. In IE8, however, the list item tabs are on separate lines When I add an XHTML doctype, the page renders correctly in IE8 except the footer is not drawn at the bottom of the page in IE8, Chrome or Firefox, i.e. the footer sits directly below the menu bar. Example doctype: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> What am I doing wrong?

I can do this with the first listing, but every listing after that isn't affected. how can i tell jquery that foreach letter apply the js code so it can toggle up/down the #show. I don't want to this 26 times (one time for each letter in the alphabet), I tried to use class instead of id but that causes all the #show to toggleup heh.

• Need help with text animation within UITableViewCell

  - by gdiphone

  I'm trying to implement a simple text animation in a custom UITableViewCell without having to go into editing mode which automatically brings up the delete button on the right. What I'm trying to accomplish is that when the label is updated by a button within the UITableviewcell, the text in the label is updated but with some smooth animation like sliding to the right since the updated text is prepended to the string. Any sample code would be great. thanks
