  • Unload image of UIImageView thats offscreen

    - by ludo
    Hi, I'm coding an application on Ipad, in a certain point of my application I present a ViewController with the presentModalViewController. My ViewController is a UISScrollView who take the larger of the modalView and inside it I display some images, I allow pagingEnabled so I can see all my images inside the scrollView. Sometimes I have to display more than 10 images inside the scrollView, so I have this error RECEIVE MEMORY WARNING LEVEL=1 after this one RECEIVE MEMORY WARNING LEVEL=2 and finnaly the debugger exited due to signal 10 (Sigbus). What can I do? is there a way to unload the image thats offscreen? or others things to do? Thanks,

  • Is there anyway to make a Rails / Rack application tell the web server to drop the connection

    - by dasil003
    There are many security reasons why one would want to drop an HTTP connection with no response (eg. OWASP's SSL best practices). When these can be detected at the server level then it's no big deal. However, what if you can only detect this condition at the application level? Does Rails, or more generally Rack, have any standard way of telling the server to drop the connection without a response? If not, are there some standard headers to pass in that will accomplish that in common web servers (I'm thinking Nginx or Apache)? Even if there is not a standard header is there a reasonable way to configure that behavior? Is this a fool's errand?

  • 500 Internal Server Error with PHP application

    - by James
    I have written a PHP application using Windows and XAMPP. I've been trying to run it on Ubuntu 10.10 with Lighttpd 1.4.26. Parts of the application work fine, but whenever I try to log in, I get a 500 - Internal Server Error page. The only thing that shows up in /var/log/lighttpd/error.log is 2011-02-25 13:43:13: (mod_fastcgi.c.2582) unexpected end-of-file (perhaps the fastcgi process died): pid: 1169 socket: unix:/tmp/php.socket-0 2011-02-25 13:43:13: (mod_fastcgi.c.3367) response not received, request sent: 1596 on socket: unix:/tmp/php.socket-0 for /~denton/customer-facing-portal/index.php?, closing connection If I had any output whatsoever from PHP, this would be a lot easier to debug.

  • Problem setText UITextView

    - by Mat
    Hi i have a problem. I have 2 viewcontroller, in the first there is a mapView that implements the function "calloutAccessoryControlTapped" to tap a button on an annotation on the mapView; in the second there is just a UITextView. I want to change the text of the UITextView (and show the SecondViewController) in the second controller once the button on annotation is clicked; here is my code (FirstViewController) Header @interface FirstViewController<MKMapViewDelegate>{ IBOutlet MKMapView *mapView; SecondViewController *secondV;} @end Implementation @implementation FirstViewController - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control{ secondV = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; NSString *myS = @"some text here"; [secondV.myTextView setText:myS]; //Switch from this to the secondview [self presentModalViewController:secondV animated:YES]; @end (SecondViewController) Header @interface SecondViewController{ IBOutlet UITextView *myTextView; } @property(nonatomic, retain)UITextView *postitTextView; - (IBAction)backToMAp; - (void)setText:(NSString *)string; @end Implementation @implementation SecondViewController - (IBAction)backToMAp{ //Back To First View; [self dismissModalViewControllerAnimated:YES];} - (void)setText:(NSString *)string{ myTextView.text = string;} In this code when i tap on the button ([self presentModalViewController:secondV animated:YES];) on annotation the first time the second view show up but the text of UITextView don't change, when i back on the FirstView ([self dismissModalViewControllerAnimated:YES];) and then again tap the button to switch again to secondView the text of UITextView change..... Sorry for long thread and for my bad english!! Thank you stack!

  • running bash scripts in php

    - by HDawg
    I have two computers. On the first computer I have apache running with all my web code. On the second computer I have large amounts of data stored with a retrieval script (the script usually takes hours to run). I am essentially creating a web UI to access this data without any time delay. so I call: exec("bash initial.bash"); this is a driver script that is in my Apache folder. It calls the script on the other computer. calling: ssh otherMachine temp.bash& this script invokes the data retrieval script on the second computer. If I call initial.bash in the terminal, everything works smoothly and successfully, but if I call it in my PHP file, then all my commands in initial.bash run, with the exception of ssh otherMachine temp.bash&. I put the & at the end of that, so that temp.bash will run in the background, since it does take a few hours to complete. I am not sure why the nested script is not running when invoked by Apache. Is there a better alternative than using exec or shell_exec to call a script, which ultimately calls another script. The reason I don't call a script on the second machine directly is because of the time it takes the program to run. Shell_exec does not render the php page until the script is complete.

    Hello, i have multilingual asp.net site. there is masterpage and default.aspx in masterpage i put two buttons one to click when i want to change the language to english, second for polish.

  • change font-size of nested elements in list

    - by John
    Hi, I have a nested list of ul elements. I would like to decrease the font size by a couple of pixels for each level down. So for example the first li elements would have font size 18px, then nested elements of that would have font size 16px and any nested elements of that would have font size 14px etc. However once the font size gets to a certain size e.g. 8px I would like to stop making them any smaller. These lists are generated on the fly so I have no way of knowing how deep they are going to be so can't just hard code the css to a certain level. Is there a way in css or JQuery where I could apply this type of formatting?

  • agent-based simulation: performance issue: Python vs NetLogo & Repast

    - by max
    I'm replicating a small piece of Sugarscape agent simulation model in Python 3. I found the performance of my code is ~3 times slower than that of NetLogo. Is it likely the problem with my code, or can it be the inherent limitation of Python? Obviously, this is just a fragment of the code, but that's where Python spends two-thirds of the run-time. I hope if I wrote something really inefficient it might show up in this fragment: UP = (0, -1) RIGHT = (1, 0) DOWN = (0, 1) LEFT = (-1, 0) all_directions = [UP, DOWN, RIGHT, LEFT] # point is just a tuple (x, y) def look_around(self): max_sugar_point = self.point max_sugar = self.world.sugar_map[self.point].level min_range = 0 random.shuffle(self.all_directions) for r in range(1, self.vision+1): for d in self.all_directions: p = ((self.point[0] + r * d[0]) % self.world.surface.length, (self.point[1] + r * d[1]) % self.world.surface.height) if self.world.occupied(p): # checks if p is in a lookup table (dict) continue if self.world.sugar_map[p].level > max_sugar: max_sugar = self.world.sugar_map[p].level max_sugar_point = p if max_sugar_point is not self.point: self.move(max_sugar_point) Roughly equivalent code in NetLogo (this fragment does a bit more than the Python function above): ; -- The SugarScape growth and motion procedures. -- to M ; Motion rule (page 25) locals [ps p v d] set ps (patches at-points neighborhood) with [count turtles-here = 0] if (count ps > 0) [ set v psugar-of max-one-of ps [psugar] ; v is max sugar w/in vision set ps ps with [psugar = v] ; ps is legal sites w/ v sugar set d distance min-one-of ps [distance myself] ; d is min dist from me to ps agents set p random-one-of ps with [distance myself = d] ; p is one of the min dist patches if (psugar >= v and includeMyPatch?) [set p patch-here] setxy pxcor-of p pycor-of p ; jump to p set sugar sugar + psugar-of p ; consume its sugar ask p [setpsugar 0] ; .. setting its sugar to 0 ] set sugar sugar - metabolism ; eat sugar (metabolism) set age age + 1 end On my computer, the Python code takes 15.5 sec to run 1000 steps; on the same laptop, the NetLogo simulation running in Java inside the browser finishes 1000 steps in less than 6 sec. EDIT: Just checked Repast, using Java implementation. And it's also about the same as NetLogo at 5.4 sec. Recent comparisons between Java and Python suggest no advantage to Java, so I guess it's just my code that's to blame? EDIT: I understand MASON is supposed to be even faster than Repast, and yet it still runs Java in the end.

  • WinForms Load Event / Static Initialization Strangeness

    - by Eric J.
    Background I'm troubleshooting an WinForms 2.0 program that's already been burned to CD for distribution to an internet-challenged target audience. Some users are experiencing a fatal error that I can reproduce locally. Reproducing the Error I get the fatal error when I log into my Vista box using a standard user that I just created, even if I run the program as administrator. I do not get the fatal error when I log in as local administrator. I'm not sure that being administrator is necessarily the trigger (since runas did not help). I have reproduced this half a dozen times under each account with consistent results. The faulty code Base.cs (base class for several user controls, only one of which is shown on first screen) private void BaseWindow_Load(object sender, EventArgs e) { // This message shown once in both cases MessageBox.Show("BaseWindow_Load for " + this.GetType().FullName); SkinManager.ApplySkin(this); } SkinManager.cs private static Skin skin = null; public static void ApplySkin(UserControl applyTo) { if (skin == null) { skin = new Skin(SkinsDirectory, "Default"); } } Skin.cs internal Skin(string skinPath, string skinName) { config = SkinConfig.Load(path); } SkinConfig.cs public static SkinConfig Load(string path) { // This message shown only once running as Admin but twice running as standard user System.Windows.Forms.MessageBox.Show("@1"); // !!! LOCK path HERE !!! } A user control loads on the first form, which triggers a call to SkinManager.ApplySkin, which checks if skin is null and, if so assigns it (without thread synchronization or recursion protection), which ultimately causes a file to be opened. When logged in as local admin, that sequence completes just fine. When logged in as my test standard user, ApplySkin is always called a second time while skin is still null, causing a second attempt to load, causing the file to be locked on the second attempt. The error handling is draconian at this point and the program terminates. The Question While this code can be easily fixed, I would like to understand why the error is happening only in some cases.

  • Best practices book for CRUD apps

    - by Kevin L.
    We will soon be designing a new tool to calculate commissions across multiple business units. This new compensation scheme is pretty clever and well thought-out, but the complexity that the implementation will involve will make the Hubble look like a toaster. A significant portion of the programming industry involves CRUD apps; updating insurance data, calculating commissions (Joel included) ...even storing questions and answers for a programmer Q&A site. We as programmers have Code Complete for the low-level formatting/style and Design Patterns for high-level architecture (to name just a few). Where’s the comparable book that teaches best practices for CRUD?

  • Python if statement efficiency

    - by Dennis
    A friend (fellow low skill level recreational python scripter) asked me to look over some code. I noticed that he had 7 separate statements that basically said. if ( a and b and c): do something the statements a,b,c all tested their equality or lack of to set values. As I looked at it I found that because of the nature of the tests, I could re-write the whole logic block into 2 branches that never went more than 3 deep and rarely got past the first level (making the most rare occurrence test out first). if a: if b: if c: else: if c: else: if b: if c: else: if c: To me, logically it seems like it should be faster if you are making less, simpler tests that fail faster and move on. My real questions are 1) When I say if and else, should the if be true, does the else get completely ignored? 2) In theory would if (a and b and c) take as much time as the three separate if statements would?

  • jquery creating stacked bar chart with flot?

    - by KittyYoung
    I'm using jquery flot and I'm trying to create a stacked bar chart, but I'm having some syntax issues... I'll post my code at the end of this, but I'm quite certain it's wrong. I do get a stacked bar chart, but there's only three columns... Basically, here is the data that I'm working with and what I want to accomplish... The first group (Focus Group 1) on each line is the bottom bar of the stacked bar, the second group (Focus Group 2) is the second, and the third group (Focus Group 3) is the top group. The "Responses" are what I want to use on the x-axis, the first number in each set is x, and the second number is y. Response1, [0, 0], [0,0], [0,9] Response2, [1, 5], [1,5], [1,11] Response3, [2, 2], [2,0], [2,8] Response4, [3, 1], [3,2], [3,6] Response5, [4, 0], [4,0], [4,7] I should also mention, that I'm not sure if a stacked chart is the best way to go... Admittedly, I'm not a very visual person, and generally find charts annoying... If there's a better way to present this data, then I am so totally open to suggestions... Essentially... I have a series of questions. Each of these questions were presented to three focus groups. Members of the focus groups selected a response. I'm trying to present the count per response, per focus group, for each question. I thought that a stacked chart would be the best way to go, but again, I'm open to other ways of doing this. The only thing is, I definitely need a visual representation of the data....

  • Using UUIDs for cheap equals() and hashCode()

    - by Tom McIntyre
    I have an immutable class, TokenList, which consists of a list of Token objects, which are also immutable: @Immutable public final class TokenList { private final List<Token> tokens; public TokenList(List<Token> tokens) { this.tokens = Collections.unmodifiableList(new ArrayList(tokens)); } public List<Token> getTokens() { return tokens; } } I do several operations on these TokenLists that take multiple TokenLists as inputs and return a single TokenList as the output. There can be arbitrarily many TokenLists going in, and each can have arbitrarily many Tokens. These operations are expensive, and there is a good chance that the same operation (ie the same inputs) will be performed multiple times, so I would like to cache the outputs. However, performance is critical, and I am worried about the expense of performing hashCode() and equals() on these objects that may contain arbitrarily many elements (as they are immutable then hashCode could be cached, but equals will still be expensive). This led me to wondering whether I could use a UUID to provide equals() and hashCode() simply and cheaply by making the following updates to TokenList: @Immutable public final class TokenList { private final List<Token> tokens; private final UUID uuid; public TokenList(List<Token> tokens) { this.tokens = Collections.unmodifiableList(new ArrayList(tokens)); this.uuid = UUID.randomUUID(); } public List<Token> getTokens() { return tokens; } public UUID getUuid() { return uuid; } } And something like this to act as a cache key: @Immutable public final class TopicListCacheKey { private final UUID[] uuids; public TopicListCacheKey(TopicList... topicLists) { uuids = new UUID[topicLists.length]; for (int i = 0; i < uuids.length; i++) { uuids[i] = topicLists[i].getUuid(); } } @Override public int hashCode() { return Arrays.hashCode(uuids); } @Override public boolean equals(Object other) { if (other == this) return true; if (other instanceof TopicListCacheKey) return Arrays.equals(uuids, ((TopicListCacheKey) other).uuids); return false; } } I figure that there are 2^128 different UUIDs and I will probably have at most around 1,000,000 TokenList objects active in the application at any time. Given this, and the fact that the UUIDs are used combinatorially in cache keys, it seems that the chances of this producing the wrong result are vanishingly small. Nevertheless, I feel uneasy about going ahead with it as it just feels 'dirty'. Are there any reasons I should not use this system? Will the performance costs of the SecureRandom used by UUID.randomUUID() outweigh the gains (especially since I expect multiple threads to be doing this at the same time)? Are collisions going to be more likely than I think? Basically, is there anything wrong with doing it this way?? Thanks.

  • Django - categories & sub-categories

    - by Bluey
    Some advice needed on how I can structure my models for my site. I have seen this post from Django project but still a little lost. Also come across Django-MPTT - but that's no help and possibly overkill. I'm looking to have categories & subcategories that are shown in the URLs like this: mysite.com/Level1/Maths/Calculations/Addition/ mysite.com/Level3/English/ mysite.com/Level2/English/Storytelling/ In my admin interface I'm looking to have drop downs for each level of category or subcategory. Also at each level I will be querying items (another model) like get all items that have the category 'Level1' AND 'Maths'. There could also be a situation where I have five or more subcategories. How is it best to create my models for best performance? It it worth using tagging instead?

  • Use absolute path for easier modify include path in future?

    config.php put at the root level, this file will be included in any pages. Then at config.php <?php define( 'ROOT_DIR', dirname(__FILE__) ); ?> So at all other pages from different sub/a.php , sub/sub/b.php directories, when I want to include a specific file in specific location, I just need to include( ROOT_DIR.'/include/functions.php' ); In windows server, the ROOT_DIR bring the value to C:/inetpub/vhosts/domain.com Is this a good/secure way? It seems like via this way, when I move the b.php to other upper level folder, I don't need to do any changes to the include file path, which is good for maintenance. Any cons? Like SEO wise, or any other reason... What you guys think.

  • Spinlocks, How Much Useful Are They?

    - by unknown
    How often do you find yourself actually using spinlocks in your code? How common is it to come across a situation where using a busy loop actually outperforms the usage of locks? Personally, when I write some sort of code that requires thread safety, I tend to benchmark it with different synchronization primitives, and as far as it goes, it seems like using locks gives better performance than using spinlocks. No matter for how little time I actually hold the lock, the amount of contention I receive when using spinlocks is far greater than the amount I get from using locks (of course, I run my tests on a multiprocessor machine). I realize that it's more likely to come across a spinlock in "low-level" code, but I'm interested to know whether you find it useful in even a more high-level kind of programming?

  • Java .doc generation

    - by bozo
    Hi, anyone knows an easy method to generate mail merge .doc file from Java? So, I want to create a Word (95/97) document in Word, put some simple placeholders in it (only single value, no iterators and other advanced tags) like the ones used with mailmerge option, and then at runtime replace those placeholders with values from Java. One option is to use Jasperreports, but this would require that I create exact replica of non-trivial Word document in Jasper format, which is not easy and is hard to change later. Is there some method of filling placeholders in Word from Java, which does not require low-level document alteration with positioning and others low-level .doc tags from code, but something like this: docPreparer.fillPlaceholder('placeholder1', 'my real value from runtime'); Some CRMs do this via ActiveX control for internet explorer, and it works great (they use Word's mailmerge) but I need an all-Java solution. Ideas? Thanks, Bozo
