  • Will Apple's new "originally written in" clause affect your decision to target the iPhone?

    - by Michael Aaron Safyan
    So, you've probably heard about Apple's change to its agreement to prohibit source-to-source translation, thereby blocking translation from Flash (in CS5) and also from Android (via XMLVM). You may also have read about a response by a well-known Adobe developer, and calls to boycott development for the iPhone. Given that this audience is a better representative of the developer community than those who post comments on the NYT, Digg, and other news sites, I was wondering what your opinions were about this decision. Will any of you switch to Android from the iPhone or avoid development on the iPhone as a result of this? Since this is fairly subjective, I am making this a community wiki. Also, please, keep things civil.

  • Problems with html forms.

    - by Michael
    My form views fine in IE7 and IE8 but FireFox does not display the form correctly: The problem is it does not display the form inside my "mainContent1" Note my code below: <div id="mainContent1"> <form action="forms.php" target="_self"> <fieldset> <legend>Postal Address</legend> <label for="street">Street address:</label> <input id="street" name="street" type="text" /> <label for=" suburb">County</label> <input id="county" name="county" type="text" /> <label for="state">State</label> <input id="state" name="state" type="text" /> <label for="zip">Zip Code</label> <input id="zip" name="zip" type="text" /> </fieldset> </form> </div>

  • Unit Testing Error - The unit test adapter failed to connect to the data source or to read the data

    - by michael.lukatchik
    I'm using VSTS 2K8 and I've set up a Unit Test Project. In it, I have a test class with a method that does a simple assertion. I'm using an Excel 2007 spreadsheet as my data source. My test method looks like this: [DataSource("System.Data.Odbc", "Dsn=Excel Files;dbq=|DataDirectory|\\MyTestData.xlsx;defaultdir=C:\\TestData;driverid=1046;maxbuffersize=2048;pagetimeout=5", "Sheet1", DataAccessMethod.Sequential)] [DeploymentItem("MyTestData.xlsx")] [TestMethod()] public void State_Value_Is_Set() { string expected = "MD"; string actual = TestContext.DataRow["State"] as string; Assert.AreEqual(expected, actual); } As indicated in the method decoration attributes, my Excel spreadsheet is on my local C:/ Drive. In it, the sheet where all of my data is located is named "Sheet1". I've copied the Excel spreadsheet into my project and I've set its Build Action = "Content" and I've set its Copy to Output Directory = "Copy if Newer". When trying to run this simple unit test, I receive the following error: The unit test adapter failed to connect to the data source or to read the data. For more information on troubleshooting this error, see "Troubleshooting Data-Driven Unit Tests" (http://go.microsoft.com/fwlink/?LinkId=62412) in the MSDN Library. Error details: ERROR [42S02] [Microsoft][ODBC Excel Driver] The Microsoft Office Access database engine could not find the object 'Sheet1'. Make sure the object exists and that you spell its name and the path name correctly. I've verified that the sheet name is spelled correctly (i.e. Sheet1) and I've verified that my data sources are set correctly. Web searches haven't turned up much at all. And I'm totally stumped. All help or input is appreciated!!!!

  • cakephp Activation Email Sending slow

    - by Michael
    Hi all, I have a simple email sender for user account activation. Depending on which email address I use, I get significantly different response times: University email - 1 minute, Gmail - 3-4 hours, Yahoo - 1 or 2 days -- which seems bizarre. Has anyone else seen this phenomenon? EDIT: There weren't many responses (even for a bounty), but I'll try to explain my problem more clearly. This probably isn't greylsting -- If I so a simple: php mail ($to, $subject, $body) // this delivers instantly. My cakephp code: function __sendActivationEmail($id) { $User = $this->User->read ( null, $id ); $this->set ( 'suffix_url', $User ['User'] ['id'] . '/' . $this->User->getActivationHash () ); $this->set ( 'username', $User ['User'] ['username'] ); $this->Email->to = $User ['User'] ['email']; $this->Email->subject = 'Test.com - ' . __ ( 'please confirm your email address', true ); $this->Email->from = '[email protected]'; $this->Email->template = 'user_confirm'; $this->Email->sendAs = 'text'; $this->Email->delivery = 'mail'; $this->Email->send (); } Causes delays from 13 minutes (ok; we'll deal with it) to 5-6 hours (less okay, since this is an activation email). For some of my users, it works instantly, but for other users (of the same service provider, i.e., gmail, it sees these delays). Any clues?

  • MySQL ORDER BY date and team

    - by Michael
    I would like to order by date and then team in a MySQL query. It should be something similar to this: SELECT * FROM games ORDER BY gamedate ASC, team_id AND it should output something like this: 2010-04-12 10:20 Game 1 Team 1 2010-04-12 11:00 Game 3 Team 1 2010-04-12 10:30 Game 2 Team 2 2010-04-14 10:00 Game 4 Team 1 So that Team 1 is under each other on the same date, but separate on a new date

  • count clicks using actionscript 3.0 in flash

    - by Michael Stone
    I want to change the variable value based on the number of clicks. So if you click the button once, the cCount should equal 1 and twice it should equal 2. Right now all I'm returning for the value is 0, no matter the amount of clicks. Any ideas? btnRaw.addEventListener(MouseEvent.CLICK, flip); btnRaw.addEventListener(MouseEvent.MOUSE_UP,count); //create the flipping function //create the variable to store the click count var cCount:Number = 0; function flip(Event:MouseEvent):void{ raw_patty_mc.gotoAndPlay(1); } function count(Event:MouseEvent):void{ cCount = cCount+1; if(cCount>3 || cCount<6){ titleText.text="See you're doing a great job at flipping the burger! "+String(cCount); } }

  • onmouseover problems with JavaScript (rendered using django and django-imagekit)

    - by Michael Moreno
    I'm using Imagekit. View.py includes: def pics(request): p = Photo.objects.all() return render_to_response('Shots.html', {'p': p}) The following simple code in the template will generate associated images: {% for p in p %} <img src = "{{ p.display.url }}"> <img src = "{{ p.thumbnail_image.url }}"> {% endfor %} I'm attempting to generate a series of thumbnails {{ p.thumbnail_image.url }} which, when mouseover'd, will generate the slightly larger version of the image, {{ p.display.url }} via Javascript. The following code in the template attempts to do so: <html> <head> <HEAD> <script language="Javascript"> { image1 = new Image image2 = new Image image1.src = {{ p.thumbnail_image.url }} image2.src = {{ p.display.url }} </script> </head> <body> {% for p in p %} <a href="" onMouseOver="document.rollover.src= image2.src onMouseOut="document.rollover.src= image1.src"> <img src="{{ p.thumbnail_image.url }}" border=0 name="rollover"></a> {% endfor %} </body> </html> This will display the series of thumbnails, but the larger image will not display when mouseover'd. I believe it has to do with how I'm specifying the variable {{ p.display.url }}.

  • PyML 0.7.2 - How to prevent accuracy from dropping after stroing/loading a classifier?

    - by Michael Aaron Safyan
    This is a followup from "Save PyML.classifiers.multi.OneAgainstRest(SVM()) object?". The solution to that question was close, but not quite right, (the SparseDataSet is broken, so attempting to save/load with that dataset container type will fail, no matter what. Also, PyML is inconsistent in terms of whether labels should be numbers or strings... it turns out that the oneAgainstRest function is actually not good enough, because the labels need to be strings and simultaneously convertible to floats, because there are places where it is assumed to be a string and elsewhere converted to float) and so after a great deal of hacking and such I was finally able to figure out a way to save and load my multi-class classifier without it blowing up with an error.... however, although it is no longer giving me an error message, it is still not quite right as the accuracy of the classifier drops significantly when it is saved and then reloaded (so I'm still missing a piece of the puzzle). I am currently using the following custom mutli-class classifier for training, saving, and loading: class SVM(object): def __init__(self,features_or_filename,labels=None,kernel=None): if isinstance(features_or_filename,str): filename=features_or_filename; if labels!=None: raise ValueError,"Labels must be None if loading from a file."; with open(os.path.join(filename,"uniquelabels.list"),"rb") as uniquelabelsfile: self.uniquelabels=sorted(list(set(pickle.load(uniquelabelsfile)))); self.labeltoindex={}; for idx,label in enumerate(self.uniquelabels): self.labeltoindex[label]=idx; self.classifiers=[]; for classidx, classname in enumerate(self.uniquelabels): self.classifiers.append(PyML.classifiers.svm.loadSVM(os.path.join(filename,str(classname)+".pyml.svm"),datasetClass = PyML.VectorDataSet)); else: features=features_or_filename; if labels==None: raise ValueError,"Labels must not be None when training."; self.uniquelabels=sorted(list(set(labels))); self.labeltoindex={}; for idx,label in enumerate(self.uniquelabels): self.labeltoindex[label]=idx; points = [[float(xij) for xij in xi] for xi in features]; self.classifiers=[PyML.SVM(kernel) for label in self.uniquelabels]; for i in xrange(len(self.uniquelabels)): currentlabel=self.uniquelabels[i]; currentlabels=['+1' if k==currentlabel else '-1' for k in labels]; currentdataset=PyML.VectorDataSet(points,L=currentlabels,positiveClass='+1'); self.classifiers[i].train(currentdataset,saveSpace=False); def accuracy(self,pts,labels): logger=logging.getLogger("ml"); correct=0; total=0; classindexes=[self.labeltoindex[label] for label in labels]; h=self.hypotheses(pts); for idx in xrange(len(pts)): if h[idx]==classindexes[idx]: logger.info("RIGHT: Actual \"%s\" == Predicted \"%s\"" %(self.uniquelabels[ classindexes[idx] ], self.uniquelabels[ h[idx] ])); correct+=1; else: logger.info("WRONG: Actual \"%s\" != Predicted \"%s\"" %(self.uniquelabels[ classindexes[idx] ], self.uniquelabels[ h[idx] ])) total+=1; return float(correct)/float(total); def prediction(self,pt): h=self.hypothesis(pt); if h!=None: return self.uniquelabels[h]; return h; def predictions(self,pts): h=self.hypotheses(self,pts); return [self.uniquelabels[x] if x!=None else None for x in h]; def hypothesis(self,pt): bestvalue=None; bestclass=None; dataset=PyML.VectorDataSet([pt]); for classidx, classifier in enumerate(self.classifiers): val=classifier.decisionFunc(dataset,0); if (bestvalue==None) or (val>bestvalue): bestvalue=val; bestclass=classidx; return bestclass; def hypotheses(self,pts): bestvalues=[None for pt in pts]; bestclasses=[None for pt in pts]; dataset=PyML.VectorDataSet(pts); for classidx, classifier in enumerate(self.classifiers): for ptidx in xrange(len(pts)): val=classifier.decisionFunc(dataset,ptidx); if (bestvalues[ptidx]==None) or (val>bestvalues[ptidx]): bestvalues[ptidx]=val; bestclasses[ptidx]=classidx; return bestclasses; def save(self,filename): if not os.path.exists(filename): os.makedirs(filename); with open(os.path.join(filename,"uniquelabels.list"),"wb") as uniquelabelsfile: pickle.dump(self.uniquelabels,uniquelabelsfile,pickle.HIGHEST_PROTOCOL); for classidx, classname in enumerate(self.uniquelabels): self.classifiers[classidx].save(os.path.join(filename,str(classname)+".pyml.svm")); I am using the latest version of PyML (0.7.2, although PyML.__version__ is 0.7.0). When I construct the classifier with a training dataset, the reported accuracy is ~0.87. When I then save it and reload it, the accuracy is less than 0.001. So, there is something here that I am clearly not persisting correctly, although what that may be is completely non-obvious to me. Would you happen to know what that is?

  • CSS : overflow : auto will not work under FireFox 3.6.2

    - by Michael Mao
    Hello everyone: This is a CSS related question, I got one good answer from my previous question, which suggested to use some CSS code like overflow:auto together with a fixed height container. And here is my actual implementation : on uni server Please follow the instructions on screen and buy more than 4 kinds of tickets. If you are using IE8, Opera, Safari, Chrome, you would notice that the lower right corner of the page now has a vertical scroll bar, which scrolls the content inside it and prevent it from overflowing. That's what I want to have in this section. Now the problem is, this would not do in FireFox 3.6.2. Am I doing something not compliant to the CSS standard or FireFox has its own way of overflow control? You can inspect the elements on screen, and all controlling functions are done in one javascript using jQuery. All CSS code are kept in a separated file as well. According to the professor, FireFox would be the target browser, although the version was set to 2.0...

  • Strange error inserting new relationship data in core-data

    - by michael
    My app will allow users to create a personalised list of events from a large list of events. I have a table view which simply displays these events, tapping on one of them takes the user to the event details view, which has a button "add to my events". In this detailed view I own the original event object, retrieved via an NSFetchedResultsController and passed to the detailed view (via a table cell, the same as the core data recipes sample). I have no trouble retrieving/displaying information from this "event". I am then trying to add it to the list of MyEvents represented by a one to many (inverse) relationship: This code: NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; [myEvents addEventObject:event];//ERROR And this code (suggested below): //would this add to or overwrite the "list" i am attempting to maintain NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; NSMutableSet *myEvent = [myEvents mutableSetValueForKey:@"event"]; [myEvent addObject:event]; //ERROR Bot produce (at the line indicated by //ERROR): *** -[NSComparisonPredicate evaluateWithObject:]: message sent to deallocated instance Seems I may have missed something fundamental. I cant glean any more information through the use of debugging tools, with my knowledge of them. 1) Is this a valid way to compile and store an editable list like this? 2) Is there a better way? 3) What could possibly be the deallocated instance in error? -- I have now modified the Event entity to have a to-many relationship called "myEvents" which referrers to itself. I can add Events to this fine, and logging the object shows the correct memory addresses appearing for the relationship after a [event addMyEventObject:event];. The same failure happens right after this however. I am still at a loss to understand what is going wrong. This is the backtrace #0 0x01f753a7 in ___forwarding___ () #1 0x01f516c2 in __forwarding_prep_0___ () #2 0x01c5aa8f in -[NSFetchedResultsController(PrivateMethods) _preprocessUpdatedObjects:insertsInfo:deletesInfo:updatesInfo:sectionsWithDeletes:newSectionNames:treatAsRefreshes:] () #3 0x01c5d63b in -[NSFetchedResultsController(PrivateMethods) _managedObjectContextDidChange:] () #4 0x0002e63a in _nsnote_callback () #5 0x01f40005 in _CFXNotificationPostNotification () #6 0x0002bef0 in -[NSNotificationCenter postNotificationName:object:userInfo:] () #7 0x01bbe17d in -[NSManagedObjectContext(_NSInternalNotificationHandling) _postObjectsDidChangeNotificationWithUserInfo:] () #8 0x01c1d763 in -[NSManagedObjectContext(_NSInternalChangeProcessing) _createAndPostChangeNotification:withDeletions:withUpdates:withRefreshes:] () #9 0x01ba25ea in -[NSManagedObjectContext(_NSInternalChangeProcessing) _processRecentChanges:] () #10 0x01bdfb3a in -[NSManagedObjectContext processPendingChanges] () #11 0x01bd0957 in _performRunLoopAction () #12 0x01f4d252 in __CFRunLoopDoObservers () #13 0x01f4c65f in CFRunLoopRunSpecific () #14 0x01f4bc48 in CFRunLoopRunInMode () #15 0x0273878d in GSEventRunModal () #16 0x02738852 in GSEventRun () #17 0x002ba003 in UIApplicationMain () Cheers.

  • Should I Return "500" or "404" if a Requested Image is not Found?

    - by Michael Robinson
    I work with code written by other people, occasionally I am left somewhat confused and at these times Stack Overflow saves me. Please, save me again. Our site allows people to upload images and later embed them within text in our site like so: <img src="http://site.com/image_script.php?p=some_image_identifier"/> My question is: If the identifier, "p", does not lead us to an image should the server return "500" or "404"? I would have thought it should be "404", but that's not what is happening right now.

  • bash : recursive listing of all files problem

    - by Michael Mao
    Run a recursive listing of all the files in /var/log and redirect standard output to a file called lsout.txt in your home directory. Complete this question WITHOUT leaving your home directory. An: ls -R /var/log/ /home/bqiu/lsout.txt I reckon the above bash command is not correct. This is what I've got so far: $ ls -1R .: cal.sh cokemachine.sh dir sort test.sh ./dir: afile.txt file subdir ./dir/subdir: $ ls -R | sed s/^.*://g cal.sh cokemachine.sh dir sort test.sh afile.txt file subdir But this still leaves all directory/sub-directory names (dir and subdir), plus a couple of empty newlines How could I get the correct result without using Perl or awk? Preferably using only basic bash commands(this is just because Perl and awk is out of assessment scope)

  • Image Gallery with JQuery Lightbox

    - by Michael
    Hi there, I've used the JQuery lightbox on a couple of websites, by having a gallery of thumbnails and the thumbnails as links to the bigger photos, such as: <a href="Images/Gallery/1.jpg" class="lightbox"> <img src="Images/Gallery/Thumbnails/1T.jpg" width="136" height="97" /> </a> My question is, using lightbox - can I make it so that I have a thumbnail image that when clicked takes you to a folder with a few pictures to cycle through, rather than just linking to one photo like in the example above? I've tried with one link like above and in the Gallery folder having more than one image, but I don't get any navigation buttons, just the one image that is linked to.

  • How do I make an HTML text box show a hint when empty?

    - by Michael L Perry
    I want the search box on my web page to display the word "Search" in gray italics. When the box receives focus, it should look just like an empty text box. If there is already text in it, it should display the text normally (black, non-italics). This will help me avoid clutter by removing the label. BTW, this is an on-page AJAX search, so it has no button.

  • Help! The log file for database 'tempdb' is full. Back up the transaction log for the database to fr

    - by michael.lukatchik
    We're running SQL Server 2000. In our database, we have an "Orders" table with approximately 750,000 rows. We can perform simple SELECT statements on this table. However, when we want to run a query like SELECT TOP 100 * FROM Orders ORDER BY Date_Ordered DESC, we receive the following message: Error: 9002, Severity: 17, State: 6 The log file for database 'tempdb' is full. Back up the transaction log for the database to free up some log space. We have other tables in our database which are similar in size of the amount of records that are in the tables (i.e. 700,000 records). On these tables, we can run any queries we'd like and we never receive a message about 'tempdb being full'. To resolve this, we've backed up our database, shrunk the actual database and also shrunk the database and files in the tempdb system database, but this hasn't resolved the issue. The size of our log file is set to autogrow. We're not sure where to go next. Are there any ideas why we still might be receiving this message? Error: 9002, Severity: 17, State: 6 The log file for database 'tempdb' is full. Back up the transaction log for the database to free up some log space.

  • Returning unique values of a multi-dimensional array with CodeIgniter PHP

    - by Michael Bradley
    Hi - I'm developing a property rentals website. The search results page will contain a list of property results. It is my intention to redefine the results, say by town, country, property type etc. So let's say for example the user searches 'France'. All of the relative properties will be returned and displayed in a list. However, I also need to reuse this array, to display only unique town names from the search results array. e.g. Montpellier, Lyon, Rennes, Nice etc. The idea is when use user click on 'Nice', only the 'Nice' properties would return. I would also like to display how many properties are in that town. The closest example as to what I want to achieve. http://www.miaandmaggie.com/dog-collars-leashes.html Any ideas how I can use my search array to display the unique towns of the search? Many thanks!

  • How to minimize total cost of shortest path tree

    - by Michael
    I have a directed acyclic graph with positive edge-weights. It has a single source and a set of targets (vertices furthest from the source). I find the shortest paths from the source to each target. Some of these paths overlap. What I want is a shortest path tree which minimizes the total sum of weights over all edges. For example, consider two of the targets. Given all edge weights equal, if they share a single shortest path for most of their length, then that is preferable to two mostly non-overlapping shortest paths (fewer edges in the tree equals lower overall cost). Another example: two paths are non-overlapping for a small part of their length, with high cost for the non-overlapping paths, but low cost for the long shared path (low combined cost). On the other hand, two paths are non-overlapping for most of their length, with low costs for the non-overlapping paths, but high cost for the short shared path (also, low combined cost). There are many combinations. I want to find solutions with the lowest overall cost, given all the shortest paths from source to target. Does this ring any bells with anyone? Can anyone point me to relevant algorithms or analogous applications? Cheers!

  • Different NSTimeZone names being returned

    - by Michael Waterfall
    I've noticed that on some devices the NSTimeZone's name method for a particular timezone can return different values. When testing the Brisbane time zone, my device returns @"Australia/Brisbane" whereas another user's device returns "Etc/GMT-10". Both iPhone's are running 3.1.2. The Date and Time Programming Guide for Cocoa states that: timeZoneWithName: The name passed to this method may be in any of the formats understood by the system, for example EST, Etc/GMT-2, America/Argentina/Buenos_Aires, Europe/Monaco, or US/Pacific, as shown in the following code fragment. I'd just like to know what could determine which value is used? The device? The language?
