  • Permission problem - users can't access main index.php anymore

    - by JMan
    From /var/www, I executed "chmod -R 774 ." and now none of my .php scripts are accessible. From my browser, when I type in mydomain.com or mydomain.com/test2.php or mydomain.com/test.php, I get the 403 Forbidden error msg. So, I changed the permissions of 3 of the .php scripts to 775, but this didn't help either.

  • Snow Leopard dock - when I minimize files, where do they go?

    - by user40150
    I upgraded to Snow Leopard a bit ago. Recently, when I minimize files in any application the files disappear - no icon that I can find, showing how to bring to a dominant window any of the minimized files. I search, can't find, have to re-boot app., and lose data. Not good. When I minimize files, where do they go, how do I reopen them, and how can I change it so icons for all minimized files remain visible? Thanks

  • Need USB drivers for Nexus One and Mac Snow Leopard?

    - by melling
    I got a AT&T compatible Nexus One that I'm trying to connect to my Mac Book Pro (Snow Leopard) for development. When I do an adb devices, it doesn't appear, and I can't do an adb install either. Until today, I've been using a G1 and I haven't had any issues. I haven't placed a SIM in the phone yet, but I don't think that should matter.

  • JavaScript Class Patterns

    - by Liam McLennan
    To write object-oriented programs we need objects, and likely lots of them. JavaScript makes it easy to create objects: var liam = { name: "Liam", age: Number.MAX_VALUE }; But JavaScript does not provide an easy way to create similar objects. Most object-oriented languages include the idea of a class, which is a template for creating objects of the same type. From one class many similar objects can be instantiated. Many patterns have been proposed to address the absence of a class concept in JavaScript. This post will compare and contrast the most significant of them. Simple Constructor Functions Classes may be missing but JavaScript does support special constructor functions. By prefixing a call to a constructor function with the ‘new’ keyword we can tell the JavaScript runtime that we want the function to behave like a constructor and instantiate a new object containing the members defined by that function. Within a constructor function the ‘this’ keyword references the new object being created -  so a basic constructor function might be: function Person(name, age) { this.name = name; this.age = age; this.toString = function() { return this.name + " is " + age + " years old."; }; } var john = new Person("John Galt", 50); console.log(john.toString()); Note that by convention the name of a constructor function is always written in Pascal Case (the first letter of each word is capital). This is to distinguish between constructor functions and other functions. It is important that constructor functions be called with the ‘new’ keyword and that not constructor functions are not. There are two problems with the pattern constructor function pattern shown above: It makes inheritance difficult The toString() function is redefined for each new object created by the Person constructor. This is sub-optimal because the function should be shared between all of the instances of the Person type. Constructor Functions with a Prototype JavaScript functions have a special property called prototype. When an object is created by calling a JavaScript constructor all of the properties of the constructor’s prototype become available to the new object. In this way many Person objects can be created that can access the same prototype. An improved version of the above example can be written: function Person(name, age) { this.name = name; this.age = age; } Person.prototype = { toString: function() { return this.name + " is " + this.age + " years old."; } }; var john = new Person("John Galt", 50); console.log(john.toString()); In this version a single instance of the toString() function will now be shared between all Person objects. Private Members The short version is: there aren’t any. If a variable is defined, with the var keyword, within the constructor function then its scope is that function. Other functions defined within the constructor function will be able to access the private variable, but anything defined outside the constructor (such as functions on the prototype property) won’t have access to the private variable. Any variables defined on the constructor are automatically public. Some people solve this problem by prefixing properties with an underscore and then not calling those properties by convention. function Person(name, age) { this.name = name; this.age = age; } Person.prototype = { _getName: function() { return this.name; }, toString: function() { return this._getName() + " is " + this.age + " years old."; } }; var john = new Person("John Galt", 50); console.log(john.toString()); Note that the _getName() function is only private by convention – it is in fact a public function. Functional Object Construction Because of the weirdness involved in using constructor functions some JavaScript developers prefer to eschew them completely. They theorize that it is better to work with JavaScript’s functional nature than to try and force it to behave like a traditional class-oriented language. When using the functional approach objects are created by returning them from a factory function. An excellent side effect of this pattern is that variables defined with the factory function are accessible to the new object (due to closure) but are inaccessible from anywhere else. The Person example implemented using the functional object construction pattern is: var personFactory = function(name, age) { var privateVar = 7; return { toString: function() { return name + " is " + age * privateVar / privateVar + " years old."; } }; }; var john2 = personFactory("John Lennon", 40); console.log(john2.toString()); Note that the ‘new’ keyword is not used for this pattern, and that the toString() function has access to the name, age and privateVar variables because of closure. This pattern can be extended to provide inheritance and, unlike the constructor function pattern, it supports private variables. However, when working with JavaScript code bases you will find that the constructor function is more common – probably because it is a better approximation of mainstream class oriented languages like C# and Java. Inheritance Both of the above patterns can support inheritance but for now, favour composition over inheritance. Summary When JavaScript code exceeds simple browser automation object orientation can provide a powerful paradigm for controlling complexity. Both of the patterns presented in this article work – the choice is a matter of style. Only one question still remains; who is John Galt?

  • How can I get image data from QTKit without color or gamma correction in Snow Leopard?

    - by Nick Haddad
    Since Snow Leopard, QTKit is now returning color corrected image data from functions like QTMovies frameImageAtTime:withAttributes:error:. Given an uncompressed AVI file, the same image data is displayed with larger pixel values in Snow Leopard vs. Leopard. Currently I'm using frameImageAtTime to get an NSImage, then ask for the tiffRepresentation of that image. After doing this, pixel values are slightly higher in Snow Leopard. For example, a file with the following pixel value in Leopard: [0 180 0] Now has a pixel value like: [0 192 0] Is there any way to ask a QTMovie for video frames that are not color corrected? Should I be asking for a CGImageRef, CIImage, or CVPixelBufferRef instead? Is there a way to disable color correction altogether prior to reading in the video files? I've attempted to work around this issue by drawing into a NSBitmapImageRep with the NSCalibratedColroSpace, but that only gets my part of the way there: // Create a movie NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys : nsFileName, QTMovieFileNameAttribute, [NSNumber numberWithBool:NO], QTMovieOpenAsyncOKAttribute, [NSNumber numberWithBool:NO], QTMovieLoopsAttribute, [NSNumber numberWithBool:NO], QTMovieLoopsBackAndForthAttribute, (id)nil]; _theMovie = [[QTMovie alloc] initWithAttributes:dict error:&error]; // .... NSMutableDictionary *imageAttributes = [NSMutableDictionary dictionary]; [imageAttributes setObject:QTMovieFrameImageTypeNSImage forKey:QTMovieFrameImageType]; [imageAttributes setObject:[NSArray arrayWithObject:@"NSBitmapImageRep"] forKey: QTMovieFrameImageRepresentationsType]; [imageAttributes setObject:[NSNumber numberWithBool:YES] forKey:QTMovieFrameImageHighQuality]; NSError* err = nil; NSImage* image = (NSImage*)[_theMovie frameImageAtTime:frameTime withAttributes:imageAttributes error:&err]; // copy NSImage into an NSBitmapImageRep (Objective-C) NSBitmapImageRep* bitmap = [[image representations] objectAtIndex:0]; // Draw into a colorspace we know about NSBitmapImageRep *bitmapWhoseFormatIKnow = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:getWidth() pixelsHigh:getHeight() bitsPerSample:8 samplesPerPixel:4 hasAlpha:YES isPlanar:NO colorSpaceName:NSCalibratedRGBColorSpace bitmapFormat:0 bytesPerRow:(getWidth() * 4) bitsPerPixel:32]; [NSGraphicsContext saveGraphicsState]; [NSGraphicsContext setCurrentContext:[NSGraphicsContext graphicsContextWithBitmapImageRep:bitmapWhoseFormatIKnow]]; [bitmap draw]; [NSGraphicsContext restoreGraphicsState]; This does convert back to a 'Non color corrected' colorspace, but the color values NOT are exactly the same as what is stored in the Uncompressed AVI files we are testing with. Also this is much less efficient because it is converting from RGB - "Device RGB" - RGB. Also, I am working in a 64-bit application, so dropping down to the Quicktime-C API is not an option. Thanks for your help.

  • How to have a consistent mail receiver name displayed in Outlook 2007 in the inbox folder

    - by usr
    Currently the same sender address appears differently in my inbox for different mails. The variations are: john[email protected] Doe, John That is because I received some mails before I changed the name to "John Doe" and some after. It is now very annoying to find mails from John because I have to look at two places in my inbox after I sort them by sender. How can I make Outlook always sho "Doe, John"?

  • How to install Mac OS X Snow Leopard server on any virtual machine with DMG?

    - by Eonil
    I'm trying to install Mac OS X Snow Leopard Server on VirtualBox. I know this is duplicated question, however another questions have no fine answer. I'm trying to install on VirtualBox on iMac. So this is pretty legal. But the problem is I want to install with DMG image. Because installing DVD drive is too slow, and I have to install Mac OS X many times. And taking DVD disc from box is annoying too. But VirtualBox fails installing. It couldn't load kernel. It installs well with DVDs. Is there any way to do this? I'm considering using other VM solutions like Parallels or VMWare if they can support install from DMG images well. If you know about them certainly, please let me know.

  • Oracle Social Network Developer Challenge: Fishbowl Solutions

    - by Kellsey Ruppel
    Originally posted by Jake Kuramoto on The Apps Lab blog. Today, I give you the final entry in the Oracle Social Network Developer Challenge, held last week during OpenWorld. This one comes from Friend of the ‘Lab and Fishbowl Solutions (@fishbowle20) hacker, John Sim (@jrsim_uix), whom you might remember from his XBox Kinect demo at COLLABORATE 12 (presentation slides and abstract) hacks and other exploits with WebCenter. We put this challenge together specifically for developers like John, who like to experiment with new tools and push the envelope of what’s possible and build cool things, and as you can see from his entry John did just that, mashing together Google Maps and Oracle Social Network into a mobile app built with PhoneGap that uses the device’s camera and GPS to keep teams on the move in touch. He calls it a Mobile GeoTagging Solution, but I think Avengers Assemble! would have equally descriptive, given that was obviously his inspiration. Here’s his description of the mobile app: My proposed solution was to design and simplify GeoLocation mapping, and automate updates for users and teams on the move; who don’t have access to a laptop or want to take their ipads out – but allow them to make quick updates to OSN and upload photos taken from their mobile device – there and then. As part of this; the plan was to include a rules engine that could be configured by the user to allow the device to automatically update and post messages when they arrived at a set location(s). Inspiration for this came from on{x} – automate your life. Unfortunately, John didn’t make it to the conference to show off his hard work in person, but luckily, he had a colleague from Fishbowl and a video to showcase his work.    Here are some shots of John’s mobile app for your viewing pleasure: John’s thinking is sound. Geolocation is usually relegated to consumer use cases, thanks to services like foursquare, but distributed teams working on projects out in the world definitely need a way to stay in contact. Consider a construction job. Different contractors all converge on a single location, and time is money. Rather than calling or texting each other and risking a distracted driving accident, an app like John’s allows everyone on the job to see exactly where the other contractors are. Using his GPS rules, they could easily be notified about how close each is to the site, definitely useful when you have a flooring contractor sitting idle, waiting for an electrician to finish the wiring. The best part is that the project manager or general contractor could stay updated on all the action (or inaction) using Oracle Social Network, either sitting at a desk using the browser app or desktop client or on the go, using one of the native mobile apps built for Oracle Social Network. I can see this being used by insurance adjusters too, and really any team that, erm, assembles at a given spot. Of course, it’s also useful for meeting at the pub after the day’s work is done. Beyond people, this solution could also be implemented for physical objects that are in route to a destination. Say you’re a customer waiting on rail shipment or a package delivery. You could track your valuable’s whereabouts easily as they report their progress via checkins. If they deviated from the GPS rules, you’d be notified. You might even be able to get a picture into Oracle Social Network with some light hacking. Thanks to John and his colleagues at Fishbowl for participating in our challenge. We hope everyone had a good experience. Make sure to check out John’s blog post on his work and the experience using Oracle Social Network. Although this is the final, official entry we had, tomorrow, I’ll show you the work of someone who finished code, but wasn’t able to make the judging event. Stay tuned.

  • Trying to reconcile global ip address and Vhosts

    I have been using my local machine as a web server for a while, and I have several websites set up locally on my machine, all with similar Vhost files like the one seen here /etc/apache2/sites-available/john.smith.com: <VirtualHost *:80> RewriteEngine on RewriteOptions Inherit ServerAdmin [email protected] ServerName john.smith.com ServerAlias www.john.smith.com DocumentRoot /home/john/smith # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn LogFormat "%v %l %u %t \"%r\" %>s %b" comonvhost CustomLog /var/log/apache2/access.log comonvhost </VirtualHost> then I set up the /etc/hosts file like so for every Vhost: 192.168.1.100 www.john.smith.com john.smith.com 192.168.1.100 www.jane.smith.com jane.smith.com 192.168.1.100 www.joe.smith.com joe.smith.com 192.168.1.100 www.jimbob.smith.com jimbob.smith.com Now I am hosting my friend's website until he gets a permanent domain. I have port forwarding set up to redirect port 80 to my machine, but I don't understand how the global ip fits into all of this. Do I for example use the following web site addresses (assume global ip is 12.34.56.789): 12.34.56.789.john.smith 12.34.56.789.jane.smith 12.34.56.789.joe.smith 12.34.56.789.jimbob.smith

  • How to resolve `bootpd` crashing constantly on Mac OS X 10.6.4 Snow Leopard Server?

    - by morgant
    I've got a Mac Pro running Mac OS X 10.6.4 Snow Leopard Server and it's recently started getting numerous 'kNetworkError's in Server Admin.app when viewing services. It's acting as a gateway w/NAT and has been so for quite some time. There is one glaring issue, bootpd crashes all the time with the following errors in `/var/log/system.log/: Aug 12 16:54:59 servername bootpd[3572]: server starting Aug 12 16:54:59 servername bootpd[3572]: server name servername.domain.tld Aug 12 16:54:59 servername bootpd[3572]: interface en0: ip 10.0.1.9 mask 255.255.255.0 Aug 12 16:54:59 servername bootpd[3572]: bsdpd: re-reading configuration Aug 12 16:54:59 servername bootpd[3572]: bsdpd: shadow file size will be set to 48 megabytes Aug 12 16:54:59 servername bootpd[3572]: bsdpd: age time 00:15:00 Aug 12 16:54:59 servername bootpd[3572]: [3572] detected buffer overflow Aug 12 16:54:59 servername com.apple.launchd[1] (com.apple.bootpd[3572]): Job appears to have crashed: Abort trap Aug 12 16:54:59 servername com.apple.ReportCrash.Root[3571]: 2010-08-12 16:54:59.828 ReportCrash[3571:2807] Saved crash report for bootpd[3572] version ???

  • SQL Joing on a one-to-many relationship

    - by Harley
    Ok, here was my original question; Table one contains ID|Name 1 Mary 2 John Table two contains ID|Color 1 Red 2 Blue 2 Green 2 Black I want to end up with is ID|Name|Red|Blue|Green|Black 1 Mary Y Y 2 John Y Y Y It seems that because there are 11 unique values for color and 1000's upon 1000's of records in table one that there is no 'good' way to do this. So, two other questions. Is there an efficient way to get this result? I can then create a crosstab in my application to get the desired result. ID|Name|Color 1 Mary Red 1 Mary Blue 2 John Blue 2 John Green 2 John Black If I wanted to limit the number of records returned how could I do something like this? Where ((color='blue') AND (color<>'red' OR color<>'green')) So using the above example I would then get back ID|Name|Color 1 Mary Blue 2 John Blue 2 John Black I connect to Visual FoxPro tables via ADODB. Thanks!

  • How to detect if certain characters are at the end of an NSString?

    - by Sheehan Alam
    Let's assume I can have the following strings: "hey @john..." "@john, hello" "@john(hello)" I am tokenizing the string to get every word separated by a space: [myString componentsSeparatedByString:@" "]; My array of tokens now contain: @john... @john, @john(hello) For these cases. How can I make sure only @john is tokenized, while retaining the trailing characters: ... , (hello) Note: I would like to be able to handle all cases of characters at the end of a string. The above are just 3 examples.
