• Why is Apache seg faulting?

  - by Jamie Howard

  We have a production server that seems to Seg Fault a few times every day. The fault is picked up by Apache and logged in the error log - but there seems to be no traffic around the time. If it's a request generating the fault then it looks like it happens before any other logging is made so I can't see how it's happening so it's very hard to debug. Our setup is Linux 64 bit Centos 5.3 Apache is loaded with the following modules apachectl -t -D DUMP_MODULES | more Loaded Modules: core_module (static) mpm_prefork_module (static) http_module (static) so_module (static) auth_basic_module (shared) auth_digest_module (shared) authn_file_module (shared) authn_alias_module (shared) authn_anon_module (shared) authn_dbm_module (shared) authn_default_module (shared) authz_host_module (shared) authz_user_module (shared) authz_owner_module (shared) authz_groupfile_module (shared) authz_dbm_module (shared) authz_default_module (shared) ldap_module (shared) authnz_ldap_module (shared) include_module (shared) log_config_module (shared) logio_module (shared) env_module (shared) ext_filter_module (shared) mime_magic_module (shared) expires_module (shared) deflate_module (shared) headers_module (shared) usertrack_module (shared) setenvif_module (shared) mime_module (shared) dav_module (shared) status_module (shared) autoindex_module (shared) info_module (shared) dav_fs_module (shared) vhost_alias_module (shared) negotiation_module (shared) dir_module (shared) actions_module (shared) speling_module (shared) userdir_module (shared) alias_module (shared) rewrite_module (shared) proxy_module (shared) proxy_balancer_module (shared) proxy_ftp_module (shared) proxy_http_module (shared) proxy_connect_module (shared) cache_module (shared) suexec_module (shared) disk_cache_module (shared) file_cache_module (shared) mem_cache_module (shared) cgi_module (shared) version_module (shared) security2_module (shared) unique_id_module (shared) fcgid_module (shared) php5_module (shared) proxy_ajp_module (shared) ssl_module (shared) Here's an exert from the Apache error log: [Mon Mar 15 06:39:25 2010] [error] [client 213.246.222.74] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 07:41:31 2010] [error] [client 213.246.222.74] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 08:24:16 2010] [error] [client 67.19.250.146] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 08:43:46 2010] [error] [client 213.246.222.74] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 08:54:02 2010] [error] [client 74.208.123.71] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 09:09:51 2010] [notice] child pid 2138 exit signal Segmentation fault (11), possible coredump in /tmp [Mon Mar 15 09:45:27 2010] [error] [client 213.246.222.74] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 09:49:05 2010] [error] [client 190.12.113.196] File does not exist: /var/www/vhosts/default/htdocs/phpMyAdmin [Mon Mar 15 09:49:06 2010] [error] [client 190.12.113.196] File does not exist: /var/www/vhosts/default/htdocs/PMA And the Access log around the same time (09:09:51): 213.246.222.74 - - [15/Mar/2010:08:43:46 +0000] "GET /" 400 561 "-" "-" 208.80.193.28 - - [15/Mar/2010:08:52:20 +0000] "GET / HTTP/1.0" 301 313 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; SU 2.009)" 74.208.123.71 - - [15/Mar/2010:08:54:02 +0000] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 298 "-" "-" 81.149.146.231 - - [15/Mar/2010:09:15:18 +0000] "GET /zabbix/ HTTP/1.1" 200 3565 "-" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_2; en-us) AppleWebKit/531.21.8 (KHTML, like Gecko) Version/4.0.4 Safari/531.21.10" 81.158.71.196 - - [15/Mar/2010:09:16:06 +0000] "GET / HTTP/1.1" 301 313 "-" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.0.18) Gecko/2010020219 Firefox/3.0.18" 213.246.222.74 - - [15/Mar/2010:09:45:27 +0000] "GET /" 400 561 "-" "-" 213.246.222.74 - - [15/Mar/2010:09:45:27 +0000] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 298 "-" "-" 190.12.113.196 - - [15/Mar/2010:09:49:05 +0000] "GET /phpMyAdmin/main.php HTTP/1.0" 404 295 "-" "-" So As you can see, there's no access logged around the time of the fault!!

Can anyone shed any light on how to move forward with this? I can confirm that the server is operational and doesn't appear to be misbehaving - the failures are so infrequent that I haven't seen it do one while making a request myself. Really appreciate any help! Cheers!

• ViewPager cycle between views?

  - by Erdem Azakli

  I want my ViewPager implementation to cycle between views instead of stopping at the last view. For example, if I have 3 views to display via a ViewPager, it should return back to the first View after the third View on fling instead of stopping at that third view.

• JSF2 and Richfaces 3.3.3 application on tomcat 6.0 crashes with a StackOverflowError

• website creation - for non web programmers?

  - by Tim

  I thought I would find decent questions and answers for this, but none really caught my eye... I am a C++ developer and I own a few domains. I'd like to start off with simple web sites for each with a minimum of time and fuss and minimum learning. I have too many projects going and don't have the time to learn how to build websites. One is for a company that currently has only a single product with custom development as well. I hacked together some really bad html with paypal links on it. It is just one simple product. I want to add uservoice to it and maybe some other stuff like FAQ, forums, etc. Right now I just link to a google group I created. Another is a startup in development phase, but we want to provide simple content like whitepapers and press releases and a section for investors. - mostly an "about us" type of thing. We will also be providing details about our product. Then there is a blog site - currently using godaddy's quickblogcast. Not a bad start but I suspect I want to move to something else. The question is - is there a framework that I can use that will make decent, if not outstanding, sites? Again, I have my hands full with three projects in addition to my day job and don't have time to learn web programming. I also don;t want to just pay a web person and then be out in the cold for upgrades, changes, etc. I have been burned before. I am happy with a web-based app or a desktop app that builds html or whatever and then I can ftp it up to the hosting servers. To summarize: - simple to get started - low time to get a web page going - ability to integrate with a few hand-done pages - pay pal integration - uservoice integration - ability to put under my svn would be nice too EDIT Thanks to the responders. I understand now why my original searches failed. I was not searching for "CMS". I'll go back and do that. I would expect that this is a many-times-duplicate... EDIT: I am considering using Wordpress and Drupal - one for each of the sites. I did one Drupal site quickly just so I could qualify for one of the Microsoft programs for discounted dev tools - anyway - it was a quick and dirty homepage and I am still on the learning curve. I look forward to playing with it. So far it has been ok. I am not sure about doing a taste-test between the two - might be a waste of time where I could just become that much better at Drupal faster than spending time on wordpress... Will keep updated. EDIT: Selecting the Drupal answer by slim for now. That is what I am going with. Don't have time to check them all out. Wordpress sounds like a good option too, but such limited time... Results: I have tried wordpress and drupal so far. Wordpress is great for blogging or for a site that you want to run ads from, but I disagree that it is ready for a corporate site, unless you want to spend lots of time making your own theme, etc. But if you spend that time, why not work with drupal? Drupal was a little intimidating at first - but after spending about 4 hours reading the overview and step-by-step guide online was a HUGE step. I got a simple site up and running easily after that. Trying to make a website just by going to the admin panel without reading anything is a waste of time. You really need to read the docs. The site is great. start here: http://drupal.org/getting-started I'd suggest drupal to anyone. It has amazing capabilities, lots of support and lots of users. Just doing blogging? Wordpress is really great for that. So now I've got two sites running with a lot of the functionality I wanted - and they look good. ONE MORE EDIT Well, I have switched back to wordpress after buying a theme and then getting help from web developers. I guess either one will work - it is just a matter of getting comfortable witht he basics, using the right tools and trying things out.

• Am I crazy? (How) should I create a jQuery content editor?

  - by Brendon Muir

  Ok, so I created a CMS mainly aimed at Primary Schools. It's getting fairly popular in New Zealand but the one thing I hate with a passion is the largely bad quality of in browser WYSIWYG editors. I've been using KTML (made by InterAKT which was purchased by Adobe a few years ago). In my opinion this editor does a lot of great things (image editing/management, thumbnailing and pretty good content editing). Unfortunately time has had its nasty way with this product and new browsers are beginning to break features and generally degrade the performance of this tool. It's also quite scary basing my livelihood on a defunct product! I've been hunting, in fact I regularly hunt around to see if anything has changed in the WYSIWYG arena. The closest thing I've seen that excites me is the WYSIHAT framework, but they've decided to ignore a pretty relevant editing paradigm which I'm going to outline below. This is the idea for my proposed editor, and I don't know of any existing products that can do this properly: Right, so the traditional model for editing let's say a Page in a CMS is to log into a 'back end' and click edit on the page. This will then load another screen with the editor in it and perhaps a few other fields. More advanced CMS's will maybe have several editing boxes that are for different portions of the page. Anyway, the big problem with this way of doing things is that the user is editing a document outside of the final context it will appear in. In the simplest terms, this means the page template. Many things can be wrong, e.g. the with of the editing area might be different to the width of the actual template area. The height is nearly always fixed because existing editors always seem to use IFRAMES for backward compatibility. And there are plenty of other beefs which I'm sure you're quite aware of if you're in this development area. Here's my editor utopia: You click 'Edit Page': The actual page (with its actual template) displays. Portions of the page have been marked as editable via a class name. You click on one of these areas (in my case it'd just be the big 'body' area in the middle of the template) and a editing bar drops down from the top of the screen with all your standard controls (bold, italic, insert image etc...). Iframes are never used, instead we rely on setting contentEditable to true on the DIV's in question. Firefox 2 and IE6 can go away, let's move on. You can edit the page knowing exactly how it will look when you save it. Because all the styles for this template are loaded, your headings will look correct, everything will be just dandy. Is this such a radical concept? Why are we still content with TinyMCE and that other editor that is too embarrassing to use because it sounds like a swear word!? Let's face the facts: I'm a JavaScript novice. I did once play around in this area using the Javascript Anthology from SitePoint as a guide. It was quite a cool learning experience, but they of course used the IFRAME to make their lives easier. I tried to go a different route and just use contentEditable and even tried to sidestep the native content editing routines (execCommand) and instead wrote my own. They kind of worked but there were always issues. Now we have jQuery, and a few libraries that abstract things like IE's lack of Range support. I'm wondering, am I crazy, or is it actually a good idea to try and build an editor around this editing paradigm using jQuery and relevant plugins to make the job easier? My actual questions: Where would you start? What plugins do you know of that would help the most? Is it worth it, or is there a magical project that already exists that I should join in on? What are the biggest hurdles to overcome in a project like this? Am I crazy? I hope this question has been posted on the right board. I figured it is a technical question as I'm wanting to know specific hurdles and pitfalls to watch out for and also if it is technically feasible with todays technology. Looking forward to hearing peoples thoughts and opinions.

• Why does my program crash when given negative values?

  - by Wayfarer

  Alright, I am very confused, so I hope you friends can help me out. I'm working on a project using Cocos2D, the most recent version (.99 RC 1). I make some player objects and some buttons to change the object's life. But the weird thing is, the code crashes when I try to change their life by -5. Or any negative value for that matter, besides -1. NSMutableArray *lifeButtons = [[NSMutableArray alloc] init]; CCTexture2D *buttonTexture = [[CCTextureCache sharedTextureCache] addImage:@"Button.png"]; LifeChangeButtons *button = nil; //top left button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(50 , size.height - 30); [button buttonText:-5]; [lifeButtons addObject:button]; //top right button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(size.width - 50 , size.height - 30); [button buttonText:1]; [lifeButtons addObject:button]; //bottom left button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(50 , 30); [button buttonText:5]; [lifeButtons addObject:button]; //bottom right button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(size.width - 50 , 30); [button buttonText:-1]; [lifeButtons addObject:button]; for (LifeChangeButtons *theButton in lifeButtons) { [self addChild:theButton]; } This is the code that makes the buttons. It simply makes 4 buttons, puts them in each corner of the screen (size is the screen) and adds their life change ability, 1,-1,5, or -5. It adds them to the array and then goes through the array at the end and adds all of them to the screen. This works fine. Here is my code for the button class: (header file) // // LifeChangeButtons.h // Coco2dTest2 // // Created by Ethan Mick on 3/14/10. // Copyright 2010 Wayfarer. All rights reserved. // #import "cocos2d.h" @interface LifeChangeButtons : CCSprite <CCTargetedTouchDelegate> { NSNumber *lifeChange; } @property (nonatomic, readonly) CGRect rect; @property (nonatomic, retain) NSNumber *lifeChange; + (id)lifeButton:(CCTexture2D *)texture; - (void)buttonText:(int)number; @end Implementation file: // // LifeChangeButtons.m // Coco2dTest2 // // Created by Ethan Mick on 3/14/10. // Copyright 2010 Wayfarer. All rights reserved. // #import "LifeChangeButtons.h" #import "cocos2d.h" #import "CustomCCNode.h" @implementation LifeChangeButtons @synthesize lifeChange; //Create the button +(id)lifeButton:(CCTexture2D *)texture { return [[[self alloc] initWithTexture:texture] autorelease]; } - (id)initWithTexture:(CCTexture2D *)atexture { if ((self = [super initWithTexture:atexture])) { //NSLog(@"wtf"); } return self; } //Set the text on the button - (void)buttonText:(int)number { lifeChange = [NSNumber numberWithInt:number]; NSString *text = [[NSString alloc] initWithFormat:@"%d", number]; CCLabel *label = [CCLabel labelWithString:text fontName:@"Times New Roman" fontSize:20]; label.position = CGPointMake(35, 20); [self addChild:label]; } - (CGRect)rect { CGSize s = [self.texture contentSize]; return CGRectMake(-s.width / 2, -s.height / 2, s.width, s.height); } - (BOOL)containsTouchLocation:(UITouch *)touch { return CGRectContainsPoint(self.rect, [self convertTouchToNodeSpaceAR:touch]); } - (void)onEnter { [[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES]; [super onEnter]; } - (void)onExit { [[CCTouchDispatcher sharedDispatcher] removeDelegate:self]; [super onExit]; } - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint touchPoint = [touch locationInView:[touch view]]; touchPoint = [[CCDirector sharedDirector] convertToGL:touchPoint]; if ( ![self containsTouchLocation:touch] ) return NO; NSLog(@"Button touch event was called returning yes. "); //this is where we change the life to each selected player NSLog(@"Test1"); NSMutableArray *tempArray = [[[UIApplication sharedApplication] delegate] selectedPlayerObjects]; NSLog(@"Test2"); for (CustomCCNode *aPlayer in tempArray) { NSLog(@"we change the life by %d.", [lifeChange intValue]); [aPlayer changeLife:[lifeChange intValue]]; } NSLog(@"Test3"); return YES; } - (void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint touchPoint = [touch locationInView:[touch view]]; touchPoint = [[CCDirector sharedDirector] convertToGL:touchPoint]; NSLog(@"You moved in a button!"); } - (void)ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event { NSLog(@"You touched up in a button"); } @end Now, This function: - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event Is where all the shit goes down. It works for all of the buttons except the -5 one. And then, it gets to: NSLog(@"we change the life by %d.", [lifeChange integerValue]); And it crashes at that statement. It only crashes when given anything less than -1. -1 works, but nothing smaller does. Here is the code in the CustomCCNode Class, "changeLife" that is being called. - (void)changeLife:(int)lifeChange { NSLog(@"change life in Custom Class was called"); NSLog(@"wtf is lifechange: %d", lifeChange); life += lifeChange; lifeString = [[NSString alloc] initWithFormat:@"%d",life]; [text setString:lifeString]; } Straight forward, but when the NSnumber is -5, it doesn't even get called, it crashes at the NSlog statement. So... what's up with that?

• How to implement Cocoa copyWithZone on derived object in MonoMac C#?

  - by Justin Aquadro

  I'm currently porting a small Winforms-based .NET application to use a native Mac front-end with MonoMac. The application has a TreeControl with icons and text, which does not exist out of the box in Cocoa. So far, I've ported almost all of the ImageAndTextCell code in Apple's DragNDrop example: https://developer.apple.com/library/mac/#samplecode/DragNDropOutlineView/Listings/ImageAndTextCell_m.html#//apple_ref/doc/uid/DTS40008831-ImageAndTextCell_m-DontLinkElementID_6, which is assigned to an NSOutlineView as a custom cell. It seems to be working almost perfectly, except that I have not figured out how to properly port the copyWithZone method. Unfortunately, this means the internal copies that NSOutlineView is making do not have the image field, and it leads to the images briefly vanishing during expand and collapse operations. The objective-c code in question is: - (id)copyWithZone:(NSZone *)zone { ImageAndTextCell *cell = (ImageAndTextCell *)[super copyWithZone:zone]; // The image ivar will be directly copied; we need to retain or copy it. cell->image = [image retain]; return cell; } The first line is what's tripping me up, as MonoMac does not expose a copyWithZone method, and I don't know how to otherwise call it. Update Based on current answers and additional research and testing, I've come up with a variety of models for copying an object. static List<ImageAndTextCell> _refPool = new List<ImageAndTextCell>(); // Method 1 static IntPtr selRetain = Selector.GetHandle ("retain"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } // Method 2 [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; _refPool.Add(cell); return cell; } [Export("dealloc")] public void Dealloc () { _refPool.Remove(this); this.Dispose(); } // Method 3 static IntPtr selRetain = Selector.GetHandle ("retain"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; _refPool.Add(cell); Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } // Method 4 static IntPtr selRetain = Selector.GetHandle ("retain"); static IntPtr selRetainCount = Selector.GetHandle("retainCount"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone (IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell () { Title = Title, Image = Image, }; _refPool.Add (cell); Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } public void PeriodicCleanup () { List<ImageAndTextCell> markedForDelete = new List<ImageAndTextCell> (); foreach (ImageAndTextCell cell in _refPool) { uint count = Messaging.UInt32_objc_msgSend (cell.Handle, selRetainCount); if (count == 1) markedForDelete.Add (cell); } foreach (ImageAndTextCell cell in markedForDelete) { _refPool.Remove (cell); cell.Dispose (); } } // Method 5 static IntPtr selCopyWithZone = Selector.GetHandle("copyWithZone:"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { IntPtr copyHandle = Messaging.IntPtr_objc_msgSendSuper_IntPtr(SuperHandle, selCopyWithZone, zone); ImageAndTextCell cell = new ImageAndTextCell(copyHandle) { Image = Image, }; _refPool.Add(cell); return cell; } Method 1: Increases the retain count of the unmanaged object. The unmanaged object will persist persist forever (I think? dealloc never called), and the managed object will be harvested early. Seems to be lose-lose all-around, but runs in practice. Method 2: Saves a reference of the managed object. The unmanaged object is left alone, and dealloc appears to be invoked at a reasonable time by the caller. At this point the managed object is released and disposed. This seems reasonable, but on the downside the base type's dealloc won't be run (I think?) Method 3: Increases the retain count and saves a reference. Unmanaged and managed objects leak forever. Method 4: Extends Method 3 by adding a cleanup function that is run periodically (e.g. during Init of each new ImageAndTextCell object). The cleanup function checks the retain counts of the stored objects. A retain count of 1 means the caller has released it, so we should as well. Should eliminate leaking in theory. Method 5: Attempt to invoke the copyWithZone method on the base type, and then construct a new ImageAndTextView object with the resulting handle. Seems to do the right thing (the base data is cloned). Internally, NSObject bumps the retain count on objects constructed like this, so we also use the PeriodicCleanup function to release these objects when they're no longer used. Based on the above, I believe Method 5 is the best approach since it should be the only one that results in a truly correct copy of the base type data, but I don't know if the approach is inherently dangerous (I am also making some assumptions about the underlying implementation of NSObject). So far nothing bad has happened "yet", but if anyone is able to vet my analysis then I would be more confident going forward.

• Is there a better way to avoid an infinite loop using winforms?

  - by Hamish Grubijan

  I am using .Net 3.5 for now. Right now I am using a using trick to disable and enable events around certain sections of code. The user can change either days, hours, minutes or total minutes, and that should not cause an infinite cascade of events (e.g. minutes changing total, total changing minutes, etc.) While the code does what I want, there might be a better / more straight-forward way. Do you know of any? For brawny points: This control will be used by multiple teams - I do not want to make it embarrassing. I suspect that I do not need to reinvent the wheel when defining hours in a day, days in week, etc. Some other standard .Net library out there must have it. Any other remarks regarding code? This using (EventHacker.DisableEvents(this)) business - that must be a common pattern in .Net ... changing the setting temporarily. What is the name of it? I'd like to be able to refer to it in a comment and also read up more on current implementations. In the general case not only a handle to the thing being changed needs to be remembered, but also the previous state (in this case previous state does not matter - events are turned on and off unconditionally). Then there is also a possibility of multi-threaded hacking. One could also utilize generics to make the code arguably cleaner. Figuring all this out can lead to a multi-page blog post. I'd be happy to hear some of the answers. P.S. Does it seem like I suffer from obsessive compulsive disorder? Some people like to get things finished and move on; I like to keep them open ... there is always a better way. // Corresponding Designer class is omitted. using System; using System.Windows.Forms; namespace XYZ // Real name masked { interface IEventHackable { void EnableEvents(); void DisableEvents(); } public partial class PollingIntervalGroupBox : GroupBox, IEventHackable { private const int DAYS_IN_WEEK = 7; private const int MINUTES_IN_HOUR = 60; private const int HOURS_IN_DAY = 24; private const int MINUTES_IN_DAY = MINUTES_IN_HOUR * HOURS_IN_DAY; private const int MAX_TOTAL_DAYS = 100; private static readonly decimal MIN_TOTAL_NUM_MINUTES = 1; // Anything faster than once per minute can bog down our servers. private static readonly decimal MAX_TOTAL_NUM_MINUTES = (MAX_TOTAL_DAYS * MINUTES_IN_DAY) - 1; // 99 days should be plenty. // The value above was chosen so to not cause an overflow exception. // Watch out for it - numericUpDownControls each have a MaximumValue setting. public PollingIntervalGroupBox() { InitializeComponent(); InitializeComponentCustom(); } private void InitializeComponentCustom() { this.m_upDownDays.Maximum = MAX_TOTAL_DAYS - 1; this.m_upDownHours.Maximum = HOURS_IN_DAY - 1; this.m_upDownMinutes.Maximum = MINUTES_IN_HOUR - 1; this.m_upDownTotalMinutes.Maximum = MAX_TOTAL_NUM_MINUTES; this.m_upDownTotalMinutes.Minimum = MIN_TOTAL_NUM_MINUTES; } private void m_upDownTotalMinutes_ValueChanged(object sender, EventArgs e) { setTotalMinutes(this.m_upDownTotalMinutes.Value); } private void m_upDownDays_ValueChanged(object sender, EventArgs e) { updateTotalMinutes(); } private void m_upDownHours_ValueChanged(object sender, EventArgs e) { updateTotalMinutes(); } private void m_upDownMinutes_ValueChanged(object sender, EventArgs e) { updateTotalMinutes(); } private void updateTotalMinutes() { this.setTotalMinutes( MINUTES_IN_DAY * m_upDownDays.Value + MINUTES_IN_HOUR * m_upDownHours.Value + m_upDownMinutes.Value); } public decimal TotalMinutes { get { return m_upDownTotalMinutes.Value; } set { m_upDownTotalMinutes.Value = value; } } public decimal TotalHours { set { setTotalMinutes(value * MINUTES_IN_HOUR); } } public decimal TotalDays { set { setTotalMinutes(value * MINUTES_IN_DAY); } } public decimal TotalWeeks { set { setTotalMinutes(value * DAYS_IN_WEEK * MINUTES_IN_DAY); } } private void setTotalMinutes(decimal nTotalMinutes) { if (nTotalMinutes < MIN_TOTAL_NUM_MINUTES) { setTotalMinutes(MIN_TOTAL_NUM_MINUTES); return; // Must be carefull with recursion. } if (nTotalMinutes > MAX_TOTAL_NUM_MINUTES) { setTotalMinutes(MAX_TOTAL_NUM_MINUTES); return; // Must be carefull with recursion. } using (EventHacker.DisableEvents(this)) { // First set the total minutes this.m_upDownTotalMinutes.Value = nTotalMinutes; // Then set the rest this.m_upDownDays.Value = (int)(nTotalMinutes / MINUTES_IN_DAY); nTotalMinutes = nTotalMinutes % MINUTES_IN_DAY; // variable reuse. this.m_upDownHours.Value = (int)(nTotalMinutes / MINUTES_IN_HOUR); nTotalMinutes = nTotalMinutes % MINUTES_IN_HOUR; this.m_upDownMinutes.Value = nTotalMinutes; } } // Event magic public void EnableEvents() { this.m_upDownTotalMinutes.ValueChanged += this.m_upDownTotalMinutes_ValueChanged; this.m_upDownDays.ValueChanged += this.m_upDownDays_ValueChanged; this.m_upDownHours.ValueChanged += this.m_upDownHours_ValueChanged; this.m_upDownMinutes.ValueChanged += this.m_upDownMinutes_ValueChanged; } public void DisableEvents() { this.m_upDownTotalMinutes.ValueChanged -= this.m_upDownTotalMinutes_ValueChanged; this.m_upDownDays.ValueChanged -= this.m_upDownDays_ValueChanged; this.m_upDownHours.ValueChanged -= this.m_upDownHours_ValueChanged; this.m_upDownMinutes.ValueChanged -= this.m_upDownMinutes_ValueChanged; } // We give as little info as possible to the 'hacker'. private sealed class EventHacker : IDisposable { IEventHackable _hackableHandle; public static IDisposable DisableEvents(IEventHackable hackableHandle) { return new EventHacker(hackableHandle); } public EventHacker(IEventHackable hackableHandle) { this._hackableHandle = hackableHandle; this._hackableHandle.DisableEvents(); } public void Dispose() { this._hackableHandle.EnableEvents(); } } } }

• OpenGL true coordinates and glutTimerFunc() problem C++

  - by Meko

  HI I am starting to learn openGl for C++.but at stating point I stucked. I have 2 question that is the coordinates for drawing some objects? I mean where is X, Y and Z? Second one I am making tutorial from some sites. and I am trying to animate my triangle.In tutorial it works but on my computer not.I Also downloaded source codes but It doesnt move. Here sample codes. I thougt that problem is glutTimerFunc(). #include #include #ifdef APPLE #include #include #else #include #endif using namespace std; //Called when a key is pressed void handleKeypress(unsigned char key, int x, int y) { switch (key) { case 27: //Escape key exit(0); } } //Initializes 3D rendering void initRendering() { glEnable(GL_DEPTH_TEST); } //Called when the window is resized void handleResize(int w, int h) { glViewport(0, 0, w, h); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective(45.0, (double)w / (double)h, 1.0, 200.0); } float _angle = 30.0f; float _cameraAngle = 0.0f; //Draws the 3D scene void drawScene() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glMatrixMode(GL_MODELVIEW); //Switch to the drawing perspective glLoadIdentity(); //Reset the drawing perspective glRotatef(-_cameraAngle, 0.0f, 1.0f, 0.0f); //Rotate the camera glTranslatef(0.0f, 0.0f, -5.0f); //Move forward 5 units glPushMatrix(); //Save the transformations performed thus far glTranslatef(0.0f, -1.0f, 0.0f); //Move to the center of the trapezoid glRotatef(_angle, 0.0f, 0.0f, 1.0f); //Rotate about the z-axis glBegin(GL_QUADS); //Trapezoid glVertex3f(-0.7f, -0.5f, 0.0f); glVertex3f(0.7f, -0.5f, 0.0f); glVertex3f(0.4f, 0.5f, 0.0f); glVertex3f(-0.4f, 0.5f, 0.0f); glEnd(); glPopMatrix(); //Undo the move to the center of the trapezoid glPushMatrix(); //Save the current state of transformations glTranslatef(1.0f, 1.0f, 0.0f); //Move to the center of the pentagon glRotatef(_angle, 0.0f, 1.0f, 0.0f); //Rotate about the y-axis glScalef(0.7f, 0.7f, 0.7f); //Scale by 0.7 in the x, y, and z directions glBegin(GL_TRIANGLES); //Pentagon glVertex3f(-0.5f, -0.5f, 0.0f); glVertex3f(0.5f, -0.5f, 0.0f); glVertex3f(-0.5f, 0.0f, 0.0f); glVertex3f(-0.5f, 0.0f, 0.0f); glVertex3f(0.5f, -0.5f, 0.0f); glVertex3f(0.5f, 0.0f, 0.0f); glVertex3f(-0.5f, 0.0f, 0.0f); glVertex3f(0.5f, 0.0f, 0.0f); glVertex3f(0.0f, 0.5f, 0.0f); glEnd(); glPopMatrix(); //Undo the move to the center of the pentagon glPushMatrix(); //Save the current state of transformations glTranslatef(-1.0f, 1.0f, 0.0f); //Move to the center of the triangle glRotatef(_angle, 1.0f, 2.0f, 3.0f); //Rotate about the the vector (1, 2, 3) glBegin(GL_TRIANGLES); //Triangle glVertex3f(0.5f, -0.5f, 0.0f); glVertex3f(0.0f, 0.5f, 0.0f); glVertex3f(-0.5f, -0.5f, 0.0f); glEnd(); glPopMatrix(); //Undo the move to the center of the triangle glutSwapBuffers(); } void update(int value) { _angle += 2.0f; if (_angle 360) { _angle -= 260; } glutPostRedisplay(); //Tell GLUT that the display has changed //Tell GLUT to call update again in 25 milliseconds glutTimerFunc(25, update, 0); } int main(int argc, char** argv) { //Initialize GLUT glutInit(&argc, argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH); glutInitWindowSize(400, 400); //Create the window glutCreateWindow("Transformations and Timers - videotutorialsrock.com"); initRendering(); //Set handler functions glutDisplayFunc(drawScene); glutKeyboardFunc(handleKeypress); glutReshapeFunc(handleResize); glutTimerFunc(24, update, 0); //Add a timer glutMainLoop(); return 0; }

• C++ Program performs better when piped

  - by ET1 Nerd

  I haven't done any programming in a decade. I wanted to get back into it, so I made this little pointless program as practice. The easiest way to describe what it does is with output of my --help codeblock: ./prng_bench --help ./prng_bench: usage: ./prng_bench $N $B [$T] This program will generate an N digit base(B) random number until all N digits are the same. Once a repeating N digit base(B) number is found, the following statistics are displayed: -Decimal value of all N digits. -Time & number of tries taken to randomly find. Optionally, this process is repeated T times. When running multiple repititions, averages for all N digit base(B) numbers are displayed at the end, as well as total time and total tries. My "problem" is that when the problem is "easy", say a 3 digit base 10 number, and I have it do a large number of passes the "total time" is less when piped to grep. ie: command ; command |grep took : ./prng_bench 3 10 999999 ; ./prng_bench 3 10 999999|grep took .... Pass# 999999: All 3 base(10) digits = 3 base(10). Time: 0.00005 secs. Tries: 23 It took 191.86701 secs & 99947208 tries to find 999999 repeating 3 digit base(10) numbers. An average of 0.00019 secs & 99 tries was needed to find each one. It took 159.32355 secs & 99947208 tries to find 999999 repeating 3 digit base(10) numbers. If I run the same command many times w/o grep time is always VERY close. I'm using srand(1234) for now, to test. The code between my calls to clock_gettime() for start and stop do not involve any stream manipulation, which would obviously affect time. I realize this is an exercise in futility, but I'd like to know why it behaves this way. Below is heart of the program. Here's a link to the full source on DB if anybody wants to compile and test. https://www.dropbox.com/s/6olqnnjf3unkm2m/prng_bench.cpp clock_gettime() requires -lrt. for (int pass_num=1; pass_num<=passes; pass_num++) { //Executes $passes # of times. clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &temp_time); //get time start_time = timetodouble(temp_time); //convert time to double, store as start_time for(i=1, tries=0; i!=0; tries++) { //loops until 'comparison for' fully completes. counts reps as 'tries'. <------------ for (i=0; i<Ndigits; i++) //Move forward through array. | results[i]=(rand()%base); //assign random num of base to element (digit). | /*for (i=0; i<Ndigits; i++) //---Debug Lines--------------- | std::cout<<" "<<results[i]; //---a LOT of output.---------- | std::cout << "\n"; //---Comment/decoment to disable/enable.*/ // | for (i=Ndigits-1; i>0 && results[i]==results[0]; i--); //Move through array, != element breaks & i!=0, new digits drawn. -| } //If all are equal i will be 0, nested for condition satisfied. -| clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &temp_time); //get time draw_time = (timetodouble(temp_time) - start_time); //convert time to dbl, subtract start_time, set draw_time to diff. total_time += draw_time; //add time for this pass to total. total_tries += tries; //add tries for this pass to total. /*Formated output for each pass: Pass# ---: All -- base(--) digits = -- base(10) Time: ----.---- secs.

• Java AD Authentication across Trusted Domains

  - by benjiisnotcool

  I am trying to implement Active Directory authentication in Java which will be ran from a Linux machine. Our AD set-up will consist of multiple servers that share trust relationships with one another so for our test environment we have two domain controllers: test1.ad1.foo.com who trusts test2.ad2.bar.com. Using the code below I can successfully authenticate a user from test1 but not on test2: public class ADDetailsProvider implements ResultSetProvider { private String domain; private String user; private String password; public ADDetailsProvider(String user, String password) { //extract domain name if (user.contains("\\")) { this.user = user.substring((user.lastIndexOf("\\") + 1), user.length()); this.domain = user.substring(0, user.lastIndexOf("\\")); } else { this.user = user; this.domain = ""; } this.password = password; } /* Test from the command line */ public static void main (String[] argv) throws SQLException { ResultSetProvider res = processADLogin(argv[0], argv[1]); ResultSet results = null; res.assignRowValues(results, 0); System.out.println(argv[0] + " " + argv[1]); } public boolean assignRowValues(ResultSet results, int currentRow) throws SQLException { // Only want a single row if (currentRow >= 1) return false; try { ADAuthenticator adAuth = new ADAuthenticator(); LdapContext ldapCtx = adAuth.authenticate(this.domain, this.user, this.password); NamingEnumeration userDetails = adAuth.getUserDetails(ldapCtx, this.user); // Fill the result set (throws SQLException). while (userDetails.hasMoreElements()) { Attribute attr = (Attribute)userDetails.next(); results.updateString(attr.getID(), attr.get().toString()); } results.updateInt("authenticated", 1); return true; } catch (FileNotFoundException fnf) { Logger.getAnonymousLogger().log(Level.WARNING, "Caught File Not Found Exception trying to read cris_authentication.properties"); results.updateInt("authenticated", 0); return false; } catch (IOException ioe) { Logger.getAnonymousLogger().log(Level.WARNING, "Caught IO Excpetion processing login"); results.updateInt("authenticated", 0); return false; } catch (AuthenticationException aex) { Logger.getAnonymousLogger().log(Level.WARNING, "Caught Authentication Exception attempting to bind to LDAP for [{0}]", this.user); results.updateInt("authenticated", 0); return true; } catch (NamingException ne) { Logger.getAnonymousLogger().log(Level.WARNING, "Caught Naming Exception performing user search or LDAP bind for [{0}]", this.user); results.updateInt("authenticated", 0); return true; } } public void close() { // nothing needed here } /** * This method is called via a Postgres function binding to access the * functionality provided by this class. */ public static ResultSetProvider processADLogin(String user, String password) { return new ADDetailsProvider(user, password); } } public class ADAuthenticator { public ADAuthenticator() throws FileNotFoundException, IOException { Properties props = new Properties(); InputStream inStream = this.getClass().getClassLoader(). getResourceAsStream("com/bar/foo/ad/authentication.properties"); props.load(inStream); this.domain = props.getProperty("ldap.domain"); inStream.close(); } public LdapContext authenticate(String domain, String user, String pass) throws AuthenticationException, NamingException, IOException { Hashtable env = new Hashtable(); this.domain = domain; env.put(Context.INITIAL_CONTEXT_FACTORY, com.sun.jndi.ldap.LdapCtxFactory); env.put(Context.PROVIDER_URL, "ldap://" + test1.ad1.foo.com + ":" + 3268); env.put(Context.SECURITY_AUTHENTICATION, simple); env.put(Context.REFERRAL, follow); env.put(Context.SECURITY_PRINCIPAL, (domain + "\\" + user)); env.put(Context.SECURITY_CREDENTIALS, pass); // Bind using specified username and password LdapContext ldapCtx = new InitialLdapContext(env, null); return ldapCtx; } public NamingEnumeration getUserDetails(LdapContext ldapCtx, String user) throws NamingException { // List of attributes to return from LDAP query String returnAttributes[] = {"ou", "sAMAccountName", "givenName", "sn", "memberOf"}; //Create the search controls SearchControls searchCtls = new SearchControls(); searchCtls.setReturningAttributes(returnAttributes); //Specify the search scope searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE); // Specify the user to search against String searchFilter = "(&(objectClass=*)(sAMAccountName=" + user + "))"; //Perform the search NamingEnumeration answer = ldapCtx.search("dc=dev4,dc=dbt,dc=ukhealth,dc=local", searchFilter, searchCtls); // Only care about the first tuple Attributes userAttributes = ((SearchResult)answer.next()).getAttributes(); if (userAttributes.size() <= 0) throw new NamingException(); return (NamingEnumeration) userAttributes.getAll(); } From what I understand of the trust relationship, if trust1 receives a login attempt for a user in trust2, then it should forward the login attempt on to it and it works this out from the user's domain name. Is this correct or am I missing something or is this not possible using the method above? --EDIT-- The stack trace from the LDAP bind is {java.naming.provider.url=ldap://test1.ad1.foo.com:3268, java.naming.factory.initial=com.sun.jndi.ldap.LdapCtxFactory, java.naming.security.authentication=simple, java.naming.referral=follow} 30-Oct-2012 13:16:02 ADDetailsProvider assignRowValues WARNING: Caught Authentication Exception attempting to bind to LDAP for [trusttest] Auth error is [LDAP: error code 49 - 80090308: LdapErr: DSID-0C0903A9, comment: AcceptSecurityContext error, data 52e, v1db0]

• Handling file upload in a non-blocking manner

  - by Kaliyug Antagonist

  The background thread is here Just to make objective clear - the user will upload a large file and must be redirected immediately to another page for proceeding different operations. But the file being large, will take time to be read from the controller's InputStream. So I unwillingly decided to fork a new Thread to handle this I/O. The code is as follows : The controller servlet /** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse * response) */ protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub System.out.println("In Controller.doPost(...)"); TempModel tempModel = new TempModel(); tempModel.uploadSegYFile(request, response); System.out.println("Forwarding to Accepted.jsp"); /*try { Thread.sleep(1000 * 60); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); }*/ request.getRequestDispatcher("/jsp/Accepted.jsp").forward(request, response); } The model class package com.model; import java.io.IOException; import java.util.concurrent.ExecutionException; import java.util.concurrent.Future; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import com.utils.ProcessUtils; public class TempModel { public void uploadSegYFile(HttpServletRequest request, HttpServletResponse response) { // TODO Auto-generated method stub System.out.println("In TempModel.uploadSegYFile(...)"); /* * Trigger the upload/processing code in a thread, return immediately * and notify when the thread completes */ try { FileUploaderRunnable fileUploadRunnable = new FileUploaderRunnable( request.getInputStream()); /* * Future<FileUploaderRunnable> future = ProcessUtils.submitTask( * fileUploadRunnable, fileUploadRunnable); * * FileUploaderRunnable processed = future.get(); * * System.out.println("Is file uploaded : " + * processed.isFileUploaded()); */ Thread uploadThread = new Thread(fileUploadRunnable); uploadThread.start(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } /* * catch (InterruptedException e) { // TODO Auto-generated catch block * e.printStackTrace(); } catch (ExecutionException e) { // TODO * Auto-generated catch block e.printStackTrace(); } */ System.out.println("Returning from TempModel.uploadSegYFile(...)"); } } The Runnable package com.model; import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.nio.ByteBuffer; import java.nio.channels.Channels; import java.nio.channels.ReadableByteChannel; public class FileUploaderRunnable implements Runnable { private boolean isFileUploaded = false; private InputStream inputStream = null; public FileUploaderRunnable(InputStream inputStream) { // TODO Auto-generated constructor stub this.inputStream = inputStream; } public void run() { // TODO Auto-generated method stub /* Read from InputStream. If success, set isFileUploaded = true */ System.out.println("Starting upload in a thread"); File outputFile = new File("D:/06c01_output.seg");/* * This will be changed * later */ FileOutputStream fos; ReadableByteChannel readable = Channels.newChannel(inputStream); ByteBuffer buffer = ByteBuffer.allocate(1000000); try { fos = new FileOutputStream(outputFile); while (readable.read(buffer) != -1) { fos.write(buffer.array()); buffer.clear(); } fos.flush(); fos.close(); readable.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println("File upload thread completed"); } public boolean isFileUploaded() { return isFileUploaded; } } My queries/doubts : Spawning threads manually from the Servlet makes sense to me logically but scares me coding wise - the container isn't aware of these threads after all(I think so!) The current code is giving an Exception which is quite obvious - the stream is inaccessible as the doPost(...) method returns before the run() method completes : In Controller.doPost(...) In TempModel.uploadSegYFile(...) Returning from TempModel.uploadSegYFile(...) Forwarding to Accepted.jsp Starting upload in a thread Exception in thread "Thread-4" java.lang.NullPointerException at org.apache.coyote.http11.InternalInputBuffer.fill(InternalInputBuffer.java:512) at org.apache.coyote.http11.InternalInputBuffer.fill(InternalInputBuffer.java:497) at org.apache.coyote.http11.InternalInputBuffer$InputStreamInputBuffer.doRead(InternalInputBuffer.java:559) at org.apache.coyote.http11.AbstractInputBuffer.doRead(AbstractInputBuffer.java:324) at org.apache.coyote.Request.doRead(Request.java:422) at org.apache.catalina.connector.InputBuffer.realReadBytes(InputBuffer.java:287) at org.apache.tomcat.util.buf.ByteChunk.substract(ByteChunk.java:407) at org.apache.catalina.connector.InputBuffer.read(InputBuffer.java:310) at org.apache.catalina.connector.CoyoteInputStream.read(CoyoteInputStream.java:202) at java.nio.channels.Channels$ReadableByteChannelImpl.read(Unknown Source) at com.model.FileUploaderRunnable.run(FileUploaderRunnable.java:39) at java.lang.Thread.run(Unknown Source) Keeping in mind the point 1., does the use of Executor framework help me in anyway ? package com.utils; import java.util.concurrent.Future; import java.util.concurrent.ScheduledThreadPoolExecutor; public final class ProcessUtils { /* Ensure that no more than 2 uploads,processing req. are allowed */ private static final ScheduledThreadPoolExecutor threadPoolExec = new ScheduledThreadPoolExecutor( 2); public static <T> Future<T> submitTask(Runnable task, T result) { return threadPoolExec.submit(task, result); } } So how should I ensure that the user doesn't block and the stream remains accessible so that the (uploaded)file can be read from it?

The Container class: <?php class Container{ private $_obj; public function __construct(){ $this->_obj = array(); } public function addData($data = array()){ if(!empty($data)){ $oldData = $this->_obj; $data = array_merge($oldData,$data); $this->_obj = $data; } } public function removeData($key){ if(!empty($key)){ $oldData = $this->_obj; unset($oldData[$key]); $this->_obj = $oldData; } } public function outputData(){ return $this->_obj; } public function give(){ return get_object_vars($this); } public function insertData($key,$value){ $this->_obj[$key] = $value; } } ? The strange thing is that my result always fall under the default switch statement and the ajax response fit both present statement. I noticed then if I just paste the Container class on the top of the handler.php file, everything works properly but it kind of defeat what I try to achieve. I tried different way to include the Container class but it seem to be than the issue is specific to this current scenario. I'm still learning PHP and my guess is that I'm missing something really basic. I also search on stackoverflow regarding the issue I'm experiencing as well as PHP.net, without success. Regards,

  hi, in my servlet i called an instance of a class.java( a class that construct an html table) in order to create this table in my jsp. the servlet is like the following: String report=request.getParameter("selrep"); String datev=request.getParameter("datepicker"); String op=request.getParameter("operator"); String batch =request.getParameter("selbatch"); System.out.println("report kind was:"+report); System.out.println("date was:"+datev); System.out.println("operator:"+op); System.out.println("batch:"+batch); if(report.equalsIgnoreCase("Report Denied")) { DeniedReportDisplay rd = new DeniedReportDisplay(); rd.ConstruireReport(); } else if(report.equalsIgnoreCase("Report Locked")) { LockedReportDisplay rl = new LockedReportDisplay(); rl.ConstruireReport(); } request.getRequestDispatcher("EspaceValidation.jsp").forward(request, response); in my jsp i can not display this table even empty or full. note: exemple a class that construct denied Report has this structure: /*constructeur*/ public DeniedReportDisplay() {} /*Methodes*/ @SuppressWarnings("unchecked") public StringBuffer ConstruireReport() { StringBuffer retour=new StringBuffer(); int i = 0; retour.append("<table border = 1 width=900 id=sheet align=left>"); retour.append("<tr bgcolor=#0099FF>" ); retour.append("<label> Denied Report</label>"); retour.append("</tr>"); retour.append("<tr>"); String[] nomCols ={"Nom","Prenom","trackingDate","activity","projectcode","WAName","taskCode","timeSpent","PercentTaskComplete","Comment"}; //String HQL_QUERY = null; for(i=0;i< nomCols.length;i++) { retour.append(("<td bgcolor=#0066CC>")+ nomCols[i] + "</td>"); } retour.append("</tr>"); retour.append("<tr>"); try { s= HibernateUtil.currentSession(); tx=s.beginTransaction(); Query query = s.createQuery("select opcemployees.Nom,opcemployees.Prenom,dailytimesheet.TrackingDate,dailytimesheet.Activity," + "dailytimesheet.ProjectCode,dailytimesheet.WAName,dailytimesheet.TaskCode," + "dailytimesheet.TimeSpent,dailytimesheet.PercentTaskComplete from Opcemployees opcemployees,Dailytimesheet dailytimesheet " + "where opcemployees.Matricule=dailytimesheet.Matricule and dailytimesheet.Etat=3 " + "group by opcemployees.Nom,opcemployees.Prenom" ); for(Iterator it=query.iterate();it.hasNext();) { if(it.hasNext()){ Object[] row = (Object[]) it.next(); retour.append("<td>" +row [0]+ "</td>");//Nom retour.append("<td>" + row [1] + "</td>");//Prenom retour.append("<td>" + row [2] + "</td>");//trackingdate retour.append("<td>" + row [3]+ "</td>");//activity retour.append("<td>" + row [4] +"</td>");//projectcode retour.append("<td>" + row [5]+ "</td>");//waname retour.append("<td>" + row [6] + "</td>");//taskcode retour.append("<td>" + row [7] + "</td>");//timespent retour.append("<td>" + row [8] + "</td>");//perecnttaskcomplete retour.append("<td><input type=text /></td>");//case de commentaire } retour.append("</tr>"); } //terminer la table. retour.append ("</table>"); tx.commit(); } catch (HibernateException e) { retour.append ("</table><H1>ERREUR:</H1>" +e.getMessage()); e.printStackTrace(); } return retour; } thanks for help.

• Server 2012 DFS New Member Issue

  - by David

  I am trying to add a new member to our DFS topology. We have 3 DCs (VMs - VMware) running Windows server 2012, two servers are located in or Primary site and the third at our DR site. Currently the two servers at our primary site are currently replicating DFS (full mesh) and are working fine. I have tried several times to add the third DC to our DFS topology, every time i configure the replication path e.g E:\MSI and click ok the MMC snap in crashes. Below is the crash info, any idea what is causing this? What i am doing is fairly straight forward and don't see why this would be happening.

• Problems configuring nameserver in plesk

  - by Saif Bechan

  Hello, i have some troubles with setting up a nameserver in PLESK for months now. I have tried all possible scenario's but i can not get this to work. I am really in need for some help, and if you can i will really appreciate it. Basically what i want is to just set up a nameserver in PLESK. I have a primary IP, and my host gave me a secondary nameserver i can use. My host is leaseweb in the netherlands. I have made some screenshots of the important parts in my opinion, maybe you guys can see some errors in them. To use the secondary nameserver provided by leaseweb i had to enable ACL on that account, i did so and made a screenshot of that too. The DNS recursion is set to localnets. These settings have not changed for months, so the dns should be fully updated everywhere. The check i run is the following: https://www.sidn.nl/over-nl/aanvraag...-server-check/ Domeinnaam (inclusief .nl): rdshosting.nl Eerste Nameserver: ns1.rdshosting.nl Eerste IP: 62.212.66.33 Tweede Nameserver: ns7.leaseweb.net Tweede ip: 62.212.76.50 If i run the dns check of the netherlands it gives me the following errors: primary name server "ns1.rdshosting.nl." Error: specified name server is not listed as NS record. All public name servers for a domain must also be listed as NS records in the zone of the domain. This domain was specified explicitly as a name server, but not found in the zone description of the primary name server. TE.6a rdshosting.nl. 86400 IN SOA ns1.rdspartners.nl. saif2k.hotmail.com. (2010031102 12H 1H 7D 3H) Error: the MNAME in SOA says "ns1.rdspartners.nl." is the primary name server. The MNAME field in the SOA record (first parameter) lists a different primary name server from the one specified for this check. RFC1035 section 3.3.13 rdshosting.nl. 86400 IN NS ns1.rdspartners.nl. Warning: hidden name server "ns1.rdspartners.nl." never used for first contact. The zone contains an NS record for a host which is not in the list of specified name servers. Hence, this name server will not be used to initiate contact to the domain. It may be used in sequential lookups, so it may still be useful. secondary name server "ns1.rdspartners.nl." [BROKEN] [HIDDEN] Failure: name server at 77.232.85.129 cannot be reached: (unknown error) The name server could not be contacted, which may be due to temporary technical problems or global DNS configuration mistakes. The internal error is shown, but not always clear about the cause. secondary name server "ns7.leaseweb.net." Info: name server looks correctly configured. I have the content of the file etc/named.conf also: // $Id: named.conf,v 1.1.1.1 2001/10/15 07:44:36 kap Exp $ // // Refer to the named(8) man page for details.

• Creating static NAT blocks outbound traffic Cisco ASA

  - by natediggs

  Hi Everyone, I have two web servers sitting behind a Cisco ASA 5505, which I don't have much experience with. I'm trying to create two static NATs. One static NAT that goes to xx.xx.xx.150 and another that goes to xx.xx.xx.151. I've created the static NAT for the .150 web server and it works FINE. Incoming and outgoing traffic work great. This is the staging web server. I now need to duplicate the setup for the production web server. So, I connect the webserver to the firewall, change the public IP address on one of the NICs reboot the server and I have outbound internet access. Then I run the command: static (inside,outside) xx.xx.xx.150 192.168.1.x which is successful. I then run the command: access-list acl-outside permit tcp any host xx.xx.xx.150 eq 80 Which is successful. I then try to browse the internet and I get nothing. I try to telnet in through port 80 and I get nothing (though I'm guessing because the response to the telnet request is being blocked). I've tried this with the production web server and then I tried it with another web server that is for internal testing and have the exact same problem. Both work fine until I run the static NAT rule and then no outbound internet access. I have a feeling that it's something simple that I'm missing, but my limited experience with this device is killing me. Below I've pasted the current configuration. I'm currently trying to get this to work on the .153 server which is the internal testing server. Once I can verify that works, I'll try it with production. : Saved : ASA Version 8.2(4) ! hostname QG domain-name XX.com enable password passwd names ! interface Ethernet0/0 switchport access vlan 2 !

• Cisco 881 losing NAT NVI translation config after reload

  - by MasterRoot24

  This is a weird one, so I'll try to explain in as much detail as I can so I'm giving the whole picture. As I've mentioned in my other questions, I'm in the process of setting up a new Cisco 881 as my WAN router and NAT firewall. I'm facing an issue where NAT NVI rules that I have configured are not enabled after a reload of the router, regardless of the fact that they are present in the startup-config. In order to clarify this a little, here's the relevant section of my current running-config: Router1#show running-config | include nat source ip nat source list 1 interface FastEthernet4 overload ip nat source list 2 interface FastEthernet4 overload ip nat source static tcp 192.168.1.x 1723 interface FastEthernet4 1723 ip nat source static tcp 192.168.1.x 80 interface FastEthernet4 80 ip nat source static tcp 192.168.1.x 443 interface FastEthernet4 443 ip nat source static tcp 192.168.1.x 25 interface FastEthernet4 25 ip nat source static tcp 192.168.1.x 587 interface FastEthernet4 587 ip nat source static tcp 192.168.1.x 143 interface FastEthernet4 143 ip nat source static tcp 192.168.1.x 993 interface FastEthernet4 993 ...and here's the mappings 'in action': Router1#show ip nat nvi translations | include --- tcp <WAN IP>:25 192.168.1.x:25 --- --- tcp <WAN IP>:80 192.168.1.x:80 --- --- tcp <WAN IP>:143 192.168.1.x:143 --- --- tcp <WAN IP>:443 192.168.1.x:443 --- --- tcp <WAN IP>:587 192.168.1.x:587 --- --- tcp <WAN IP>:993 192.168.1.x:993 --- --- tcp <WAN IP>:1723 192.168.1.x:1723 --- --- ...and here's proof that the mappings are saved to startup-config: Router1#show startup-config | include nat source ip nat source list 1 interface FastEthernet4 overload ip nat source list 2 interface FastEthernet4 overload ip nat source static tcp 192.168.1.x 1723 interface FastEthernet4 1723 ip nat source static tcp 192.168.1.x 80 interface FastEthernet4 80 ip nat source static tcp 192.168.1.x 443 interface FastEthernet4 443 ip nat source static tcp 192.168.1.x 25 interface FastEthernet4 25 ip nat source static tcp 192.168.1.x 587 interface FastEthernet4 587 ip nat source static tcp 192.168.1.x 143 interface FastEthernet4 143 ip nat source static tcp 192.168.1.x 993 interface FastEthernet4 993 However, look what happens after a reload of the router: Router1#reload Proceed with reload?

I presume that this is because my interfaces are using ip nat enable for use with NVI mappings, instead of ip nat inside/outside. So, I re-apply the mappings: Router1#configure ter Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z.

• Load balancing with multiple gateways

  - by ttouch

  I have to different ISPs, each on each own network. The main connects via ethernet and the secondary via wifi. The two networks have no relation at all. I just connect to them simultaneously.

Once you cancel your account with any business, their promises of keeping the information about their customers private no longer apply... you're not a customer any longer. This is in the large category of business behaviors that individuals would consider immoral and deceptive -- and businesses know are not illegal. -- "_ankh," writing on the XNStalk mailing list ________________________________________________________________________ ..TBTF's long hiatus is drawing to a close Hail subscribers to the TBTF mailing list. Some 2,000 [1] of you have signed up since the last issue [2] was mailed on 2000-07-20. This brief note is the first of several I will send to this list to excise the dead addresses prior to resuming regular publication. While you time the contractions of the newsletter's rebirth, I in- vite you to read the TBTF Log [3] and sign up for its separate free subscription. Send "subscribe" (no quotes) with any subject to [email protected] . I mail out collected Log items on Sun- days. If you need to stay more immediately on top of breaking stories, pick up the TBTF Log's syndication file [4] or read an aggregator that does. Examples are Slashdot's Cheesy Portal [5], Userland [6], and Sitescooper [7]. If your news obsession runs even deeper and you own an SMS-capable cell phone or PDA, sign up on TBTF's WebWire- lessNow portal [8]. A free call will bring you the latest TBTF Log headline, Jargon Scout [9] find, or Siliconium [10]. Two new columnists have bloomed on TBTF since last summer: Ted By- field's roving_reporter [11] and Gary Stock's UnBlinking [12]. Late- ly Byfield has been writing in unmatched depth about ICANN, but the roving_reporter nym's roots are in commentary at the intersection of technology and culture. Stock's UnBlinking latches onto topical sub- jects and pursues them to the ends of the Net. These writers' voices are compelling and utterly distinctive.
