  • I did my own web framework: now, how keep it sync with applications? must I use versions?

    - by Daniel Koch
    ... and I did the first web application using it, now I'm going to create the second. In this first web application I enhanced the framework's core library with new things and promptly updated framework branch. I'm using bazaar to keep framework and web application committed. The application was in the beginning, a full branch of framework source tree, now I'm updating framework manually at every change on core files. (copying changed files from web app to framework's branch). With this second web application that I'm going to create, I need to know about versions (or revisions) which the application is based. If I found a bug in this version I can fix and then sync files with first web application no worrying: functions will be the same to this application. If I'm going to make changes in core (new behavior, new functions in library or something new in source tree) it must be named as "new version". What's the best way to do this? Because I'm using a Distributed Version Control System (bazaar), I'm not dealing with VERSIONS, but revision numbers that change every time. Please fresh my mind with new ideas.

  • LBA48 in Linux SCSI ATA Passthrough

    - by Ben Englert
    I am writing a custom disk monitoring/diagnostics app which, among other things, needs to do stuff to SATA disks behind a SAS PCI card under Linux. So far I am following this guide as well as the example code in sg_utils to pass ATA taskfiles through the SCSI layer. Seems to be working okay. However, in both cases, the CDB data structure (pointed to by the cmdp member of the sg_io argument to the ioctl) has only one unsigned char worth of space for the number of sectors. If you look at the ata_taskfile structure in linux\ata.h you'll see that it has an "nsect" and a "hob_nsect" field - high order bits for the sector count, to support LBA48. It turns out that in my application I need LBA48 support. So, anyone know how to set up an sg_io_hdr structure with an LBA48 sector count?

  • How to efficiently convert String, integer, double, datetime to binary and vica versa?

    - by Ben
    Hi, I'm quite new to C# (I'm using .NET 4.0) so please bear with me. I need to save some object properties (their properties are int, double, String, boolean, datetime) to a file. But I want to encrypt the files using my own encryption, so I can't use FileStream to convert to binary. Also I don't want to use object serialization, because of performance issues. The idea is simple, first I need to somehow convert objects (their properties) to binary (array), then encrypt (some sort of xor) the array and append it to the end of the file. When reading first decrypt the array and then somehow convert the binary array back to object properties (from which I'll generate objects). I know (roughly =) ) how to convert these things by hand and I could code it, but it would be useless (too slow). I think the best way would be just to get properties' representation in memory and save that. But I don't know how to do it using C# (maybe using pointers?). Also I though about using MemoryStream but again I think it would be inefficient. I am thinking about class Converter, but it does not support toByte(datetime) (documentation says it always throws exception). For converting back I think the only options is class Converter. Note: I know the structure of objects and they will not change, also the maximum String length is also known. Thank you for all your ideas and time. EDIT: I will be storing only parts of objects, in some cases also parts of different objects (a couple of properties from one object type and a couple from another), thus I think that serialization is not an option for me.

  • jQuery Dialog form serialize reposting incorrect data on subsequent uses

    - by Ben Dauphinee
    I'm working with forms inside jQuery Dialog, and am having some issues with the data it's posting. First load and save works fine, posts the correct data. Until I refresh the page though, every subsequent load seems to work, as in the correct data is in the form, however, when saved, the data from the first load is what is posted every time. function formdialog(url, tack, divid, scriptload){ $.getJSON(url+tack+"/form", function(data){ var formwin = '<div><form id="formdialog">'+data['form']+'</form></div>'; var dialog = $(formwin).dialog({ title: data['title'], autoOpen: false, modal: true, buttons: { "Save": function(){ $.post(url+tack+"/process", $("#formdialog").serialize(), function(data){ alert($("#formdialog").serialize()); $(this).dialog('close'); $(this).remove(); } ); }, "Cancel": function(){$(this).dialog('close'); $(this).remove();} } }); dialog.dialog("open"); }); } $(function(){ $("a.edlnk").click(function(){ var url = $(this).attr("href"); formdialog(CONFIG_HREF_SITE+"ajax/"+appControl, "/"+url, divid); return false; }); });

  • How can I get started with PHPUnit, where my class construct requires a preconfigured db connection?

    - by Ben Dauphinee
    I have a class that uses a lot of database internally, so I built the constructor with a $db handle that I am supposed to pass to it. I am just getting started with PHPUnit, and I am not sure how I should go ahead and pass the database handle through setup. public function setUp(/*do I pass a database handle through here, using a reference? aka &$db*/){ $this->_acl = new acl; } public function __construct(Zend_Db_Adapter_Abstract $db, $config = array()){

  • Visual Studio + Database Edition + CDC = Deploy Fail

    - by Ben
    Hi All, I've got a database using change data capture (CDC) that is created from a Visual Studio database project (GDR2). My problem is that I have a stored procedure that is analyzing the CDC information and then returning data. How is that a problem you ask? Well, the order of operation is as follows. Pre-deployment Script Tables Indexes, keys, etc. Procedures Post-deployment Script Inside the post-deployment script is where I enable CDC. Here-in lies the problem. The procedure that is acting on the CDC tables is bombing because they don't exist yet! I've tried to put the call to sys.sp_cdc_enable_table in the script that creates the table, but it doesn't like that. Error 102 TSD03070: This statement is not recognized in this context. C:...\Schema Objects\Schemas\dbo\Tables\Foo.table.sql 20 1 Foo Is there a better/built-in way to enable CDC such that it's references are available when the stored procedures are created? Is there a way to run a script after tables are created but before other objects are created? How about a way to create the procedure dependencies be damned? Or maybe I'm just doing things that shouldn't be done?!?! Now, I have a work around. Comment out the sproc body Deploy (CDC is created) Uncomment sproc Deploy Everything is great until the next time I update a CDC tracked table. Then I need to comment out the 'offending' procedure. Thanks for reading my question and thanks for your help!

  • Valid signed Hex to long function

    - by Ben
    I am trying to convert a 24bit Hexadecimal string (6 characters) signed in two's complement to a long int in C. This is the function I have come up with: long int hex2li (char string[]) { char *pEnd; long int result = strtol (string, &pEnd, 16); if (strcmp (pEnd, "") == 0) { if (toupper (string[0]) == 'F') { return result - 16777216; } else { return result; } } return LONG_MIN; } Is it valid? Is there a better way of doing this?

  • Bypassing Javascript form handler

    - by Ben Aston
    We are writing an ASP.NET MVC application. By default, if the client browser has Javascript, the handler for every form on the page is set, by Javascript, to be one that sends the submission down an Ajax "pipe" (progressive enhancement). But, for one form (on a page of several), I'd like this handler to be bypassed/ignored. Is there a simple way to do this? Perhaps by overriding the handler by specifying my own onsubmit event directly in the DOM - or some other method? We use jQuery, so those libraries are available to me.

  • IEnumerable<T> ToArray usage, is it a copy or a pointer?

    - by Daniel
    I am parsing an arbitrary length byte array that is going to be passed around to a few different layers of parsing. Each parser creates a Header and a Packet payload just like any ordinary encapsulation. And my problem lies in how the encapsulation holds its packet byte array payload. Say i have a 100 byte array, and it has 3 levels of encapsulation. 3 packet objects will be created and i want to set the payload of these packets to the corresponding position in the byte array of the packet. For example lets say the payload size is 20 for all levels, then imagine it has a public byte[] Payload on each object. However the problem is that this byte[] Payload is a copy of the original 100 bytes. So i'm going to end up with 160 bytes in memory instead of 100. If it were in c++ i could just easily use a pointer however i'm writing this in c#. So i created the following class: public class PayloadSegment<T> : IEnumerable<T> { public readonly T[] Array; public readonly int Offset; public readonly int Count; public PayloadSegment(T[] array, int offset, int count) { this.Array = array; this.Offset = offset; this.Count = count; } public T this[int index] { get { if (index < 0 || index >= this.Count) throw new IndexOutOfRangeException(); else return Array[Offset + index]; } set { if (index < 0 || index >= this.Count) throw new IndexOutOfRangeException(); else Array[Offset + index] = value; } } public IEnumerator<T> GetEnumerator() { for (int i = Offset; i < Offset + Count; i++) yield return Array[i]; } System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator() { IEnumerator<T> enumerator = this.GetEnumerator(); while (enumerator.MoveNext()) { yield return enumerator.Current; } } } This way i can simply reference a position inside the original byte array but use positional indexing. However if i do something like: PayloadSegment<byte> something = new PayloadSegment<byte>(someArray, 5, 10); byte[] somethingArray = something.ToArray(); Will the somethingArray be a copy of the bytes, or a reference to the original PayloadSegment which in turn is a reference to the original byte array? Sorry it was hard to word this lol _<

  • What's the equivalent of use-commit-times for git?

    - by Ben W
    I need the timestamps of files on my local and on my server to be in sync. This is accomplished with Subversion by setting use-commit-times=true in the config so that the last modified of each file is when it was committed. Each time I clone my repository, I want the timestamps of files to reflect when they were last changed in the remote repository, not when I cloned the repo. Is there any way to do this with git?

  • Same font, character spacing and line-height but different results

    - by Ben Huh
    The introduction of @font-face in CSS3 allows web designers to use fonts that look the same across all browsers. That is what I thought until trying it out with the following code in jsFiddle: HTML: <div> The_Quick_Brown<br> Fox_Jumps_Over<br> The_Lazy_Dog </div> CSS: @font-face { font-family: 'Open Sans'; font-style: normal; font-weight: 400; src: url('http://themes.googleusercontent.com/static/fonts/opensans/v6/cJZKeOuBrn4kERxqtaUH3T8E0i7KZn-EPnyo3HZu7kw.woff') format('woff'); } div { display: block; width: 496px; height: 86px; font-size: 1.3em; font-family: 'Open Sans'; font-style: normal; margin: 0; border: 0; padding: 0; background: cyan; letter-spacing: 1.44em; line-height: 1.44; overflow: hidden; } This is the view from Firefox 12.0. Take note of the partially obscured 'o' in 'brown', the position of 'g' in 'dog' and the underscore '_' at the bottom edge. This is the view from Google Chrome 19.0. Despite explicitly setting letter-spacing and line-height for the same font, why are the results still different?

  • dojo.connect won't connect 'onclick' with button

    - by Daniel
    I'm running into a problem using dojo.connect() to connect an 'onclick' event with this button: <button dojoType="dijit.form.Button" widgetId="inbox_button" id="inbox_button">Inbox</button> and the code making the connection is: var inbox_button=dojo.byId("inbox_button"); dojo.connect(inbox_button,'onclick',function(){ var container=dijit.byId("center"); container.addChild(new dijit.layout.ContentPane({region: "left", content: "...", style: "width: 100px;"})) }); However, instead of executing the function when the button is clicked, ANY onclick event triggers the function, and I end up with a lot of children containers. Even though I'm pretty certain the .connect() function should be available as part of dojo's base functionality, I've 'required' it explicitly: dojo.require("dojo._base.connect"); Any ideas as to why this might be happening?

  • How can I force a jQuery plugin to refresh the data it has loaded?

    - by Ben Dauphinee
    I am working with jQuery Pagination, and a popup form. On saving the data in the form, how would I go about forcing the Pagination plugin to reload the data it would load for whatever page I am on, without reloading the entire webpage? Ex: Item 1 Item 2 Item 3 Add Item-Item 23-Save-Reload List Item 1 Item 2 Item 3 Item 23 http://d-scribe.de/webtools/jquery-pagination/lib/jquery_pagination/README

  • How can I simply change a class variable from another class in ObjectiveC?

    - by Daniel
    I simply want to change a variable of an object from another class. I can compile without a problem, but my variable always is set to 'null'. I used the following code: Object.h: @interface Object : NSObject { //... NSString *color; //... } @property(nonatomic, retain) NSString* color; + (id)Object; - (void)setColor:(NSString*)col; - (NSString*)getColor; @end Object.m: +(id)Object{ return [[[Object alloc] init] autorelease]; } - (void)setColor:(NSString*)col { self.color = col; } - (NSString*)getColor { return self.color; } MyViewController.h #import "Object.h" @interface ClassesTestViewController : UIViewController { Object *myObject; UILabel *label1; } @property UILabel *label1; @property (assign) Object *myObject; @end MyViewController.m: #import "Object.h" @implementation MyViewController @synthesize myObject; - (void)viewDidLoad { [myObject setColor:@"red"]; NSLog(@"Color = %@", [myObject getColor]); [super viewDidLoad]; } The NSLog message is always Color = (null) I tried many different ways to solve this problem, but no success. Any help would be appreciated.

  • JSF - Session Bean restart on logout and login

    - by Ben
    Hi, I have a web application with a backing bean which has the context of the current logged in user. It is implemented on JSF. When the user logs out he is forwarded to a login screen (in another JSP page). I would like the current session to be erased when that happens and a new one to be created the next time the user logs in and enters the application. My question is - how do you delete a session? (I guess the new session will be created automatically the next time the user enters the link) This is kinda newb i guess, but I couldn't find a solution for this. Thanks for the Help!

  • View controller/NIB architecture for non-navigation application with transitions?

    - by Ben
    I'm tinkering with an app that doesn't use the UINavigation root view control system, so I don't have natural ownership for each app "view". I essentially have two basic views, a document list view, and a document edit view. I'm playing with UIView animation for getting from a selected document to the edit view. I also have a toolbar that exists in both "views". Because I don't have UINavigation running the show for me, I have a tendency to just throw more and more stuff into one NIB and one view controller that owns the whole container. But now I'm trying to figure out how to segue from the document list view to the edit view if the edit view lives inside a different NIB, preserving the toolbar too. Anyone have thoughts or experience on app structures like this? I find the docs lacking on best practices around code/UI structure for anything except trivial one-screen apps or full-on navigation apps. Thanks!
