  • How do I copy or move an NSManagedObject from one context to another?

    - by Aeonaut
    I have what I assume is a fairly standard setup, with one scratchpad MOC which is never saved (containing a bunch of objects downloaded from the web) and another permanent MOC which persists objects. When the user selects an object from scratchMOC to add to her library, I want to either 1) remove the object from scratchMOC and insert into permanentMOC, or 2) copy the object into permanentMOC. The Core Data FAQ says I can copy an object like this: NSManagedObjectID *objectID = [managedObject objectID]; NSManagedObject *copy = [context2 objectWithID:objectID]; (In this case, context2 would be permanentMOC.) However, when I do this, the copied object is faulted; the data is initially unresolved. When it does get resolved, later, all of the values are nil; none of the data (attributes or relationships) from the original managedObject are actually copied or referenced. Therefore I can't see any difference between using this objectWithID: method and just inserting an entirely new object into permanentMOC using insertNewObjectForEntityForName:. I realize I can create a new object in permanentMOC and manually copy each key-value pair from the old object, but I'm not very happy with that solution. (I have a number of different managed objects for which I have this problem, so I don't want to have to write and update copy: methods for all of them as I continue developing.) Is there a better way?

  • Dropdown OnSelectedIndexChanged not firing

    - by Jim
    The OnSelectedIndexChanged event is not firing for my dropdown box. All forums I have looked at told me to add the AutoPostBack="true", but that didn't change the results. HTML: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:Label ID="Label1" runat="server" Text="Current Time: " /> <br /> <asp:Label ID="lblCurrent" runat="server" Text="Label" /><br /><br /> <asp:DropDownList ID="cboSelectedLocation" runat="server" AutoPostBack="true" OnSelectedIndexChanged="cboSelectedLocation_SelectedIndexChanged" /><br /><br /> <asp:Label ID="lblSelectedTime" runat="server" Text="Label" /> </div> </form> </body> </html> Code behind: public partial class _Default : System.Web.UI.Page { string _sLocation = string.Empty; string _sCurrentLoc = string.Empty; TimeSpan _tsSelectedTime; protected void Page_Load(object sender, EventArgs e) { AddTimeZones(); cboSelectedLocation.Focus(); lblCurrent.Text = "Currently in " + _sCurrentLoc + Environment.NewLine + DateTime.Now; lblSelectedTime.Text = _sLocation + ":" + Environment.NewLine + DateTime.UtcNow.Add(_tsSelectedTime); } //adds all timezone displaynames to combobox //defaults combo location to seoul, South Korea //defaults current location to current location private void AddTimeZones() { foreach(TimeZoneInfo tz in System.TimeZoneInfo.GetSystemTimeZones()) { string s = tz.DisplayName; cboSelectedLocation.Items.Add(s); if (tz.StandardName == "Korea Standard Time") cboSelectedLocation.Text = s; if (tz.StandardName == System.TimeZone.CurrentTimeZone.StandardName) _sCurrentLoc = tz.StandardName; } } //changes timezone name and time depending on what is selected in the cbobox. protected void cboSelectedLocation_SelectedIndexChanged(object sender, EventArgs e) { foreach (TimeZoneInfo tz in System.TimeZoneInfo.GetSystemTimeZones()) { if (cboSelectedLocation.Text == tz.DisplayName) { _sLocation = tz.StandardName; _tsSelectedTime = tz.GetUtcOffset(DateTime.UtcNow); } } } } Any advice into what to look at for a rookie asp coder?

  • I know the big picture but can't put it in place

    - by Simbilim
    Hi, I'm interested in web development and by that I mean the bigger projects like facebook or twitter. I know the basics of java, css, php and mysql. I know there is a lot more out there. I read about it. But I don't know what the purpose is and how to put in place. Things like: Scribe, thrift, casandra, Unix/Linux, shell/perl/python scripting, PostgreSQL, MongoDB, non-relational NoSQL datastores, JVM, nginx I want to know why they need it, how they use it and what te purpose is. What I need is a book like technical background of facebook for dummies or so. Are there any books or websites that explain this from scratch? Thank you!

  • HP DL380 RAID5 Mistake

    - by Eddy
    I had drives fail in both logical drives on a server. When I replaced failed 146GB drive in Raid 5 array with four (4) 146GB drives. On reboot the Smart Array controller asked if I wanted to accept data loss. Guess mistake to choose yes. Can't seem to find a way to get system to repair RAID5 but it seems to want to just create a new partition. Is there anyway I can go back and get the system to restore the data from other three drives now that I said accept data loss?

  • View Docs and PDFs Directly in Google Chrome

    - by Matthew Guay
    Would you like to view documents, presentations, and PDFs directly in Google Chrome?  Here’s a handy extension that makes Google Docs your default online viewer so don’t have to download the file first. Getting Started By default, when you come across a PDF or other common document file online in Google Chrome, you’ll have to download the file and open it in a separate application. It’d be much easier to simply view online documents directly in Chrome.  To do this, head over to the Docs PDF/PowerPoint Viewer page on the Chrome Extensions site (link below), and click Install to add it to your browser. Click Install to confirm that you want to install this extension. Extensions don’t run by default in Incognito mode, so if you’d like to always view documents directly in Chrome, open the Extensions page and check Allow this extension to run in incognito. Now, when you click a link for a document online, such as a .docx file from Word, it will open in the Google Docs viewer. These documents usually render in their original full-quality.  You can zoom in and out to see exactly what you want, or search within the document.  Or, if it doesn’t look correct, you can click the Download link in the top left to save the original document to your computer and open it in Office.   Even complex PDF render very nicely.  Do note that Docs will keep downloading the document as you’re reading it, so if you jump to the middle of a document it may look blurry at first but will quickly clear up. You can even view famous presentations online without opening them in PowerPoint.  Note that this will only display the slides themselves, but if you’re looking for information you likely don’t need the slideshow effects anyway.   Adobe Reader Conflicts If you already have Adobe Acrobat or Adobe Reader installed on your computer, PDF files may open with the Adobe plugin.  If you’d prefer to read your PDFs with the Docs PDF Viewer, then you need to disable the Adobe plugin.  Enter the following in your Address Bar to open your Chrome Plugins page: chrome://plugins/ and then click Disable underneath the Adobe Acrobat plugin. Now your PDFs will always open with the Docs viewer instead. Performance Who hasn’t been frustrated by clicking a link to a PDF file, only to have your browser pause for several minutes while Adobe Reader struggles to download and display the file?  Google Chrome’s default behavior of simply downloading the files and letting you open them is hardly more helpful.  This extension takes away both of these problems, since it renders the documents on Google’s servers.  Most documents opened fairly quickly in our tests, and we were able to read large PDFs only seconds after clicking their link.  Also, the Google Docs viewer rendered the documents much better than the HTML version in Google’s cache. Google Docs did seem to have problem on some files, and we saw error messages on several documents we tried to open.  If you encounter this, click the Download link in the top left corner to download the file and view it from your desktop instead. Conclusion Google Docs has improved over the years, and now it offers fairly good rendering even on more complex documents.  This extension can make your browsing easier, and help documents and PDFs feel more like part of the Internet.  And, since the documents are rendered on Google’s servers, it’s often faster to preview large files than to download them to your computer.

  • Javascript CS-PRNG - 64-bit random

    - by Jack
    Hi, I need to generate a cryptographically secure 64-bit unsigned random integer in Javascript. The first problem is that Javascript only allows 64-bit signed integers, so 9223372036854775808 is the biggest supported integer without going into floating point use I think? To fix this I can use a big number library, no problem. My Method: var randNum = SHA256( randBigInt(128, 0) ) % 2^64; Where SHA256() is a secure hash function and randBigInt() is defined below as a non-crypto PRNG, im giving it a 128bit seed so brute force shouldn't be a problem. randBigInt(n,s) //return an n-bit random BigInt (n>=1). If s=1, then the most significant of those n bits is set to 1. Is this a secure method to generate a cryptographically secure 64-bit random int? And importantly does taking the 2^64 mod guarantee 100% I have a 64-bit number? An abstract example, say this number is prime (it isn't i know), I will use it in the Galois Field [2^p], where p must be 64bits so that every possible 1-63bit number is a field element. In this query, my random int must be larger than any 63-bit number. And Im not sure im correct in taking the 2^64 mod of a 256bit hash output. Thanks (hope that makes sense)

  • What did I do wrong here when trying to unit test a class that references a web service

    - by zachary
    So I had a class that referenced a class that referenced another class that called a web service. So I learn how to create an interface using partial classes. I inject the web service through the constructor. Then my unit test fails because I am newing up the actual web service in the second level of the class. So I end up modifying all three classes to pass the web service down through the constructor... was not happy :-( gave up.... what should I be doing in this case?

What is done about this? Do I have to make ALL links using the newer rewritten format? .htaccess: Options +FollowSymLinks Options +Indexes RewriteEngine On RewriteCond %{REQUEST_URI} !^/ad\.php RewriteRule ^annons/(.*)$ ad.php?ad_id=$1 [NC,L] Thanks

  • Magento: server requirements for a quite big shop to run smoothly

    - by david parloir
    Hi, I'm working on a quite big magento: it will have 50 different shops (1 magento install, 1 admin to rule them all) for start, this number is expected to raise in the future, and a catalog of more than 1k products. This catalog will be shared by all shops. I'm concerned about the server requirements I need for this to run smoothly. So far this is what I've found to get the most of it: Caching: using magento's cache with APC, MySQL's querys Images sprite in the theme use FastCGI instead of mod_php database clustering: I don't think it will be necesary for 1k products, what do you think? using Zend Server Are there other thing I can do in order to improve magento's performance? I'd like to know all I need from the beginning so I can find the right server. thanks in advance.

  • How should I implement lazy session creation in PHP?

    - by Adam Franco
    By default, PHP's session handling mechanisms set a session cookie header and store a session even if there is no data in the session. If no data is set in the session then I don't want a Set-Cookie header sent to the client in the response and I don't want an empty session record stored on the server. If data is added to $_SESSION, then the normal behavior should continue. My goal is to implement lazy session creation behavior of the sort that Drupal 7 and Pressflow where no session is stored (or session cookie header sent) unless data is added to the $_SESSION array during application execution. The point of this behavior is to allow reverse proxies such as Varnish to cache and serve anonymous traffic while letting authenticated requests pass through to Apache/PHP. Varnish (or another proxy-server) is configured to pass through any requests without cookies, assuming correctly that if a cookie exists then the request is for a particular client. I have ported the session handling code from Pressflow that uses session_set_save_handler() and overrides the implementation of session_write() to check for data in the $_SESSION array before saving and will write this up as library and add an answer here if this is the best/only route to take. My Question: While I can implement a fully custom session_set_save_handler() system, is there an easier way to get this lazy session creation behavior in a relatively generic way that would be transparent to most applications?
