• image archive VS image strip

  - by DevA

  Hi, i've noticed that plenty of games / applications (very common on mobile builds) pack numerous images into an image strip. I figured that the advantages in this are making the program more tidy (file system - wise) and reducing (un)installation time. During the runtime of the application, the entire image strip is allocated and copied from FS to RAM. On the contrary, images can be stored in an image archive and unpacked during runtime to a number of image structures in RAM. The way I see it, the image strip approach is less efficient because of worse caching performance and because that even if the optimal rectangle packing algorithm is used, there will be empty spaces between the stored images in the strip, causing a waste of RAM. What are the advantages in using an image strip over using an image archive file?

• DDD: Client-side script to enforce invariants

  - by Mosh

  Hello, One thing that I'm confused about in regards to DDD is that our domain is supposed to handle all business logic and enforce invariants. I have noticed some people (me included) handle certain invariants in the presentation layer (i.e. WebForms, Views, etc) with javascript. This is mainly done to improve performance so the server is not hit for every request which may be invalid. Even though this approach may be beneficial performance-wise, it violates DDD principles. What if the business rules are changed? This way we don't have a rich domain where all the business rules are captured. In case of a change, we should change the domain as well as the presentation layer. Has anyone come across this situation before? I'd like to know your thoughts on this. Cheers, Mosh

• What's the best way to read/write array contents from/to binary files in C#?

  - by Eric

  I would like to read and write the contents of large ( 2GB), raw volume files (e.g. MRI scans). These files are just a sequence of e.g. 32 x 32 x 32 floats so they map well to 1D arrays. I would like to be able to read the contents of the binary volume files into 1D arrays of e.g. float or ushort (depending on the data type of the binary files) and similarly export the arrays back out to the raw volume files. What's the best way to do this with C#? Read/Write them 1 element at a time with BinaryReader/BinaryWriter? Read them piece-wise into byte arrays with FileStream.Read and then do a System.Buffer.BlockCopy between arrays (keeping in mind that I want 2GB arrays)? Write my own Reader/Writer?

• Mysql results sorted by list which is unique for each user

  - by ADAM

  Ive got a table of thousands of products and 50 or so authenticated users. These users all show the products on their own web sites and they all require the ability to have them ordered differently. Im guesing i need some kind of seperate table for the orders which contains the product_id, user_id and order column? How do i do this the most efficiently in mysql so as to be very fast, and not slow down if i get millions of products in the database. Is it even wise to do it in mysql or should i be using some kind of other index like solr/lucene? My Product table is called "products" My User table is called "users" A good example of the functionality i need is google search where you can order/supress the results if you are logged in. edit: the product results will be paginated and the users have the authority to edit the products, so its not just ready only

• using document.createDocumentFragment() child dom elements that contain jQuery.data

  - by taber

  I want to use document.createDocumentFragment() to create an optimized collection of HTML elements that contain ".data" coming from jQuery (v 1.4.2), but I'm kind of stuck on how to get the data to surface from the HTML elements. Here's my code: var genres_html = document.createDocumentFragment(); $(xmlData).find('genres').each(function(i, node) { var genre = document.createElement('a'); $(genre).addClass('button') .attr('href', 'javascript:void(0)') .html( $(node).find('genreName:first').text() ) .data('genreData', { id: $(node).find('genreID:first').text() }); genres_html.appendChild( genre.cloneNode(true) ); }); $('#list').html(genres_html); // error: $('#list a:first').data('genreData') is null alert($('#list a:first').data('genreData').id); What am I doing wrong here? I suspect it's probably something with .cloneNode() not carrying over the data when the element is appended to the documentFragment. Sometimes there are tons of rows so I want to keep things pretty optimized, speed-wise. Thanks!

• Can I distribute my MATLAB program as open source?

  - by yuk

  I know, the general answer will be yes, but here is my situation. I got a plotting function from one MATLAB's toolbox and modified its m-file to draw what I need. Eventually this function became a part of program I would like to distribute as an open source (or under other license). Can I do this? Well, may be it was not wise to create a function in such a way, but I didn't think about distribution at that time. The function still depends on other functions in this toolbox, so a potential user supposed to have a license for it. Any thoughts, recommendations? Have you ever modified MATLAB's m-files directly?

• In ASP.NET, Can I Delete a row in GridView while the primary key of that table is not loaded into the gridview?

  - by Reddy S R

  Hi, I have a table with primary key whose importance is technically high and none business wise. So, when I display the table data to user, I would like not to show him the primary key. Even if I load it in sqldatasource and dont show (I did this by removing the cloumn in "Columns" tag of GridView), I am not able to update or delete row using the built-in UpdateCommand & DeleteCommand. I have created the delete paramters but it does nothing when I hit the delete button. How to get around it? Thanks R S Reddy

• How safe am I signing into Google Spreadsheets with yeroon.net/ggplot2

  - by Farrel

  I am impressed by what I have seen of yeroon.net/ggplot2 which is a web interface for Hadley Wickham's R package ggplot2. I want to try it out on my own data. The part that has me very excited is that one can use data stored in one's own Google spreadsheet as the data. One just signs into their Google Account so that yeroon.net/ggplot2 can access the spreadsheet list. I have been hesitant to do it. If I sign in whilst on yeroon.net am I handing over my username and password to a third party? It would not be wise of me to divulge my google password to third parties since Google is fast becoming my repository of everything. How do I know if Jeroon's application is using ClientLogin or OAuth? My understanding is very basic and may be wrong but nevertheless here it is. OAuth would be better since it does not actually pass the password onto the third party application.

• Simplest solution to replace a tiny file inside an MSI?

  - by sascha

  Many of our customers have access to InstallShield, WISE or AdminStudio. These aren't a problem. I'm hoping there is some way I can provide our smaller customers without access to commercial repackaging tools a freely available set of tools and steps to do the file replacement themselves. Only need to replace a single configuration file inside a compressed MSI, the target user can be assumed to already have Orca installed, know how to use this to customize the Property table (to embed license details for GPO deployment) and have generated an MST file. Disclaimer: this is very similar to another question but both questions and answers in that thread are not clear.

• Is it a good idea to cache data from web services into a database?

  - by Thierry Lam

  Let's assume that Stackoverflow offers web services where you can retrieve all the questions asked by a specific user. A request to get all question from user A can result in the following json output: { { "question": "What is rest?", "date_created": "20/02/2010", "votes": 1, }, { "question": "Which database to use for ...", "date_created": "20/07/2009", "votes": 5, }, } If I want to manipulate and present the data in any ways that I want, will it be wise to dump it in a local database? At some point, I will also want to retrieve all answers for each question and store them in a local database. The workflow that I'm thinking is: User logs in. Web services retrieve all questions asked by the logged in user, dump them in a local database. User wants all answers for a specific question, another web service does the retrieval and dump them in a local database. After user logs out, delete from the local database all questions and answers from that user.

• Prevent SQL injection from form-generated SQL.

  - by Markos Fragkakis

  Hi all, I have a search table where user will be able to filter results with a filter of the type: Field [Name], Value [John], Remove Rule Field [Surname], Value [Blake], Remove Rule Field [Has Children], Value [Yes], Remove Rule Add Rule So the user will be able to set an arbitrary set of filters, which will result essentially in a completely dynamic WHERE clause. In the future I will also have to implement more complicated logical expressions, like Where (name=John OR name=Nick) AND (surname=Blake OR surname=Bourne), Of all 10 fields the user may or may not filter by, I don't know how many and which filters the user will set. So, I cannot use a prepared statement (which assumes that at least we know the fields in the WHERE clause). This is why prepared statements are unfortunately out of the question, I have to do it with plain old, generated SQL. What measures can I take to protect the application from SQL Injection (REGEX-wise or any other way)?

• Code working in jsFiddle but not in browser...

  - by Jascination

  I'm trying to run the following code, written on my local machine: http://www.jsfiddle.net/WShdx/3/ Functionality-wise (ignore the broken images in the previous and next buttons, and the wrongly-sized main images) the click/hover function is working properly in jsfiddle. However, on my local machine it's not working at all. For all intents and purposes the code is identical, except the local copy has this head section to load in the javascript/css files that are contained within the jsfiddle page: <head> <title>Jquery Wizard</title> <link href="style.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script> <script src="wizard.js" type="text/javascript" ></script> </head> Is there some wonderful function of jsFiddle that is making my code magically work, or am I missing something here?

• ASP.NET Web Service - Passing a base object with list/collection?

  - by schooner

  We need to create a simple web service in ASP.NET that can be called from PHP or other languages. This in turn will be used to update records in a database for an item submission. The core part is fairly simple, we have a base set of fields for the object - first name, last name, birth date, city, etc. In addition however we need to accept a list of items associated with that object that can range from 0-n. Jan 1 2009, ABC May 1 2010, 123 Jun 30 2010, XXXXX What would be the best way to structure this so it can be easily passed to the ASP.NET web service and processed as a single call for the entire object? Would passing the list of items as a single delimted string be a wise approach? Ex: Jan 1 2009, ABC|May 1 2010, 123|Jun 30 2010, XXXXX

• How to develop a Google Gadget compatible server

  - by Peter Stegnar

  I am going to develop a Google Gadget container site, that will be able to host OpenSocial compatible widgets (that I believe are Google gadgets, too, right?). Do you have any guidance where to start? I know that the good start is the iGoogle Developer Home site and that framework what I would like exists - Shindig, but is little clumsy. Tutorial links do not work, for start. Do you think it would be wise to use Shindig? Maybe just for a start and then develop any customizations, if needed? Or would be wiser to start from scratch? So where to start? Do you have any advices, tips or other useful resources to get on faster with this topic? I guess I can start with Compliance - Gadget Server?

• Using Spotlight as the "database" of an application

  - by vicvicvic

  I'm developing an OS X application to organize "things" (as iTunes is to music and iPhoto to photos). Instead of having my own database and index, I'm considering using Spotlight to essentially serve this purpose. Has anyone tried this? Is it wise? The main benefit, as I see it, would be simplicity and avoiding redundancy. It seems a bit wasteful to implement my own index machinery when OS X comes with one built in. I have little experience working with Spotlight, however. From a user's perspective, I do know that it has been slow and imprecise in older versions of OS X. I also have a gut-feeling that since it's aimed at searching the whole filesystem, using it for "local" purposes becomes hackish. Obviously, my applications's index needs to constantly be up-to-date. Can mdimport be used for this?

• Rotation towards an object in 3d space

  - by retoucher

  hello, i have two coordinates on a 2d plane in 3d space, and am trying to rotate one coordinate (a vector) to face the other coordinate. my vertical axis is the y-axis, so if both of the coordinates are located flat on the 2d plane, they would both have a y-axis of 0, and their x and z coordinates determine their position length/width-wise on the plane. right now, i'm calculating the angle like so (language agnostic): angle = atan2(z2-z1,x2-x1); and am rotating/translating in space like so: pushMatrix(); rotateY(angle); popMatrix(); this doesn't seem to be working though. are my calculations/process correct?

• In what order does evaluation of post-increment operator happen?

  - by sum1stolemyname

  Given std::vector<CMyClass> objects; CMyClass list[MAX_OBJECT_COUNT]; Is it wise to do this? for(unsigned int i = 0; i < objects.size(); list[i] = objects.at(i++)); Or should I expand my loop to this? for(unsigned int i = 0; i < objects.size(); i++) { list[i] = objects.at(i); }

• Security precautions and techniques for a User-submitted Code Demo Area

  - by Jack W-H

  Hey folks Maybe this isn't really feasible. But basically, I've been developing a snippet-sharing website and I would like it to have a 'live demo area'. For example, you're browsing some snippets and click the Demo button. A new window pops up which executes the web code. I understand there are a gazillion security risks involved in doing this - XSS, tags, nasty malware/drive by downloads, pr0n, etc. etc. etc. The community would be able to flag submissions that are blatantly naughty but obviously some would go undetected (and, in many cases, someone would have to fall victim to discover whatever nasty thing was submitted). So I need to know: What should I do - security wise - to make sure that users can submit code, but that nothing malicious can be run - or executed offsite, etc? For your information my site is powered by PHP using CodeIgniter. Jack

• std::string == operator not working

  - by Paul

  Hello, I've been using std::string's == operator for years on windows and linux. Now I am compiling one of my libraries on linux, it uses == heavily. On linux the following function fails, because the == returns false even when the strings are equal (case sensitive wise equal) const Data* DataBase::getDataByName( const std::string& name ) const { for ( unsigned int i = 0 ; i < m_dataList.getNum() ; i++ ) { if ( m_dataList.get(i)->getName() == name ) { return m_dataList.get(i); } } return NULL; } The getName() method is declared as follows virtual const std::string& getName() const; I am building with gcc 4.4.1 and libstdc++44-4.4.1. Any ideas? it looks perfectly valid to me. Paul

• Why packets injected with libpcap are duplicated?

  - by r0u1i

  I'm using sharppcap in order to send packets as part of a monitoring system. Usually it works well but I've encountered the strangest bug on a hosted vista machine and I would like your help. On that virtual vista machine, injected packets are duplicated. That is, if I send a ping request using libpcap, it somehow gets duplicated and I get two requests on the destination machine. The two requests are almost identical byte-wise, and the only difference between them is that the second packet's TTL field is one minus the original packet's value. Using wireshark I can see the packet gets duplicated before it (and its clone) leave the vista machine. The problem is manifested even when using other tools for injecting packets using libpcap (namely PlayCap). Any ideas?

• difference between a lexical, morphological and semantic mistakes?

  - by AnH

  Hi there, I just want to make sure that I understood the differences between a lexical, morphological and semantic mistakes correctly. If am not mistaken semantic mistakes deal with problems concerning meanings, for example writing a sentence that is correct grammar wise but doesn't make any sense is a semantic mistake, morphological mistakes deals more or less on how the word should look like, for example childrenS is a morphological mistake, so that leaves lexical mistakes, what are those exactly?? can someone sum up the differences between those 3 mistakes please so that I may know for sure that I got them down correctly? Thank you in advance

• Whats the best way to stop this app crash when buttons rapidly pressed iphone obj-c

  - by dubbeat

  Hi, I'm not entirely sure why this crash is happening and I'd like to get advice on the best way to deal with it. My app has 3 buttons. Each button requests a different XML file from a server which is used to populate a table view. If I rapidly press the buttons in sequence , button 1 button 2 button3 button 1 button 2 button3 button 1 button 2 button3 the application quits. What could be causing this. Would id be in the NSURLRequest side of things or the table view population side? How would you suggest I stop this behaviour? I was going to just set a boolean "isRequesting" to true when a button is pressed and set it to false when the table view is finished populating. If any button is pressed while isRequesting is True they do nothing. Does that sound wise or is there a better way? Thanks, dub

• What's so bad about in-line CSS?

  - by ChessWhiz

  When I see website starter code and examples, the CSS is always in a separate file, named something like "main.css", "default.css", or "Site.css". However, when I'm coding up a page, I'm often tempted to throw the CSS in-line with a DOM element, such as by setting "float: right" on an image. I get the feeling that this is "bad coding", since it's so rarely done in examples. I understand that if the style will be applied to multiple objects, it's wise to follow "Don't Repeat Yourself" (DRY) and assign it to a CSS class to be referenced by each element. However, if I won't be repeating the CSS on another element, why not in-line the CSS as I write the HTML? The question: Is using in-line CSS considered bad, even if it will only be used on that element? If so, why? Example (is this bad?): <img src="myimage.gif" style="float:right" />
