• Question about software that tracks divs better than notepad++

  - by Jeff

  I recently got hired as a web developer, and the project that I am overseeing has a formatting issue on one of the pages because one of the divs is out of whack. It is a fairly complex page with quite a bit of php, and from what I can gather, I am missing a </div> tag somewhere, and accordingly everything is messed up. I am currently using notepad++, which is decent at lining up divs, meaning that if you click on the opening div tag, it will highlight purple and also highlight the closing one. But it seems as though if you have div tags that span several lines (hundreds) it won't work. Has anyone else run into a similar situation? Is there a better editor I could be using that would do a better job of helping me with my div issue? Or do I have to go through and line up the divs 1 by 1? (there are like over 100). Please let me know!! Thanks

• How can I get the palette of an 8-bit surface in SDL.NET/Tao.SDL?

  - by lolmaster

  I'm looking to get the palette of an 8-bit surface in SDL.NET if possible, or (more than likely) using Tao.SDL. This is because I want to do palette swapping with the palette directly, instead of blitting surfaces together to replace colours like how you would do it with a 32-bit surface. I've gotten the SDL_Surface and the SDL_PixelFormat, however when I go to get the palette in the same way, I get a System.ExecutionEngineException: private Tao.Sdl.Sdl.SDL_Palette GetPalette(Surface surf) { // Get surface. Tao.Sdl.Sdl.SDL_Surface sdlSurface = (Tao.Sdl.Sdl.SDL_Surface)System.Runtime.InteropServices.Marshal.PtrToStructure(surf.Handle, typeof(Tao.Sdl.Sdl.SDL_Surface)); // Get pixel format. Tao.Sdl.Sdl.SDL_PixelFormat pixelFormat = (Tao.Sdl.Sdl.SDL_PixelFormat)System.Runtime.InteropServices.Marshal.PtrToStructure(sdlSurface.format, typeof(Tao.Sdl.Sdl.SDL_PixelFormat)); // Execution exception here. Tao.Sdl.Sdl.SDL_Palette palette = (Tao.Sdl.Sdl.SDL_Palette)System.Runtime.InteropServices.Marshal.PtrToStructure(pixelFormat.palette, typeof(Tao.Sdl.Sdl.SDL_Palette)); return palette; } When I used unsafe code to get the palette, I got a compile time error: "Cannot take the address of, get the size of, or declare a pointer to a managed type ('Tao.Sdl.Sdl.SDL_Palette')". My unsafe code to get the palette was this: unsafe { Tao.Sdl.Sdl.SDL_Palette* pal = (Tao.Sdl.Sdl.SDL_Palette*)pixelFormat.palette; } From what I've read, a managed type in this case is when a structure has some sort of reference inside it as a field. The SDL_Palette structure happens to have an array of SDL_Color's, so I'm assuming that's the reference type that is causing issues. However I'm still not sure how to work around that to get the underlying palette. So if anyone knows how to get the palette from an 8-bit surface, whether it's through safe or unsafe code, the help would be greatly appreciated.

• What git branching models actually work - the final question

  - by UncleCJ

  In our company we have successfully deployed git and we are currently using a simple trunk/release/hotfixes branching model. However, this has it's problems, I have some key issues of confusion in the community which would be awesome to have answered here. Maybe my hopes for an Alexander stroke are too great, quite possibly I'll decompose this question into more manageable issues, but here's my first shot. Workflows / branching models - below are the three main descriptions of this I have seen, but they are partially contradicting each other or don't go far enough to sort out the subsequent issues we've run into (as described below). Thus our team so far defaults to not so great solutions. Are you doing something better? gitworkflows(7) Manual Page (nvie) A successful Git branching model (reinh) A Git Workflow for Agile Teams Merging vs rebasing (tangled vs sequential history) - the bids on this are as confusing as it gets. Should one pull --rebase or wait with merging back to the mainline until your task is finished? Personally I lean towards merging since this preserves a visual illustration of on which base a task was started and finished, and I even prefer merge --no-ff for this purpose. It has other drawbacks however. Also many haven't realized the useful property of merging - that it isn't commutative (merging a topic branch into master does not mean merging master into the topic branch). I am looking for a natural workflow - sometimes mistakes happen because our procedures don't capture a specific situation with simple rules. For example a fix needed for earlier releases should of course be based sufficiently downstream to be possible to merge upstream into all branches necessary (is the usage of these terms clear enough?). However it happens that a fix makes it into the master before the developer realizes it should have been placed further downstream, and if that is already pushed (even worse, merged or something based on it) then the option remaining is cherry-picking, with it's associated perils... What simple rules like such do you use? Also in this is included the awkwardness of one topic branch necessarily excluding other topic branches (assuming they are branched from a common baseline). Developers don't want to finish a feature to start another one feeling like the code they just wrote is not there anymore How to avoid creating merge conflicts (due to cherry-pick)? What seems like a sure way to create a merge conflict is to cherry-pick between branches, they can never be merged again? Would applying the same commit in revert (how to do this?) in either branch possibly solve this situation? This is one reason I do not dare to push for a largely merge-based workflow. How to decompose into topical branches? - We realize that it would be awesome to assemble a finished integration from topic branches, but often work by our developers is not clearly defined (sometimes as simple as "poking around") and if some code has already gone into a "misc" topic, it can not be taken out of there again, according to the question above? How do you work with defining/approving/graduating/releasing your topic branches? Proper procedures like code review and graduating would of course be lovely, but we simply cannot keep things untangled enough to manage this - any suggestions? integration branches, illustration please? Vote and comment as much as you'd like, I'll try to keep the issue page clear and informative enough. Thanks! Below is a list of related topics on stackoverflow I have checked out: What are some good strategies to allow deployed applications to be hotfixable? Workflow description for git usage for in-house development Git workflow for corporate Linux kernel development How do you maintain development code and production code? (thanks for this PDF!) git releases management Git Cherry-pick vs Merge Workflow How to cherry-pick multiple commits How do you merge selective files with git-merge?

• Help with 2-part question on ASP.NET MVC and Custom Security Design

  - by JustAProgrammer

  I'm using ASP.NET MVC and I am trying to separate a lot of my logic. Eventually, this application will be pretty big. It's basically a SaaS app that I need to allow for different kinds of clients to access. I have a two part question; the first deals with my general design and the second deals with how to utilize in ASP.NET MVC Primarily, there will initially be an ASP.NET MVC "client" front-end and there will be a set of web-services for third parties to interact with (perhaps mobile, etc). I realize I could have the ASP.NET MVC app interact just through the Web Service but I think that is unnecessary overhead. So, I am creating an API that will essentially be a DLL that the Web App and the Web Services will utilize. The API consists of the main set of business logic and Data Transfer Objects, etc. (So, this includes methods like CreateCustomer, EditProduct, etc for example) Also, my permissions requirements are a little complicated. I can't really use a straight Roles system as I need to have some fine-grained permissions (but all permissions are positive rights). So, I don't think I can really use the ASP.NET Roles/Membership system or if I can it seems like I'd be doing more work than rolling my own. I've used Membership before and for this one I think I'd rather roll my own. Both the Web App and Web Services will need to keep security as a concern. So, my design is kind of like this: Each method in the API will need to verify the security of the caller In the Web App, each "page" ("action" in MVC speak) will also check the user's permissions (So, don't present the user with the "Add Customer" button if the user does not have that right but also whenever the API receives AddCustomer(), check the security too) I think the Web Service really needs the checking in the DLL because it may not always be used in some kind of pre-authenticated context (like using Session/Cookies in a Web App); also having the security checks in the API means I don't really HAVE TO check it in other places if I'm on a mobile (say iPhone) and don't want to do all kinds of checking on the client However, in the Web App I think there will be some duplication of work since the Web App checks the user's security before presenting the user with options, which is ok, but I was thinking of a way to avoid this duplication by allowing the Web App to tell the API not check the security; while the Web Service would always want security to be verified Is this a good method? If not, what's better? If so, what's a good way of implementing this. I was thinking of doing this: In the API, I would have two functions for each action: // Here, "Credential" objects are just something I made up public void AddCustomer(string customerName, Credential credential , bool checkSecurity) { if(checkSecurity) { if(Has_Rights_To_Add_Customer(credential)) // made up for clarity { AddCustomer(customerName); } else // throw an exception or somehow present an error } else AddCustomer(customerName); } public void AddCustomer(string customerName) { // actual logic to add the customer into the DB or whatever // Would it be good for this method to verify that the caller is the Web App // through some method? } So, is this a good design or should I do something differently? My next question is that clearly it doesn't seem like I can really use [Authorize ...] for determining if a user has the permissions to do something. In fact, one action might depend on a variety of permissions and the View might hide or show certain options depending on the permission. What's the best way to do this? Should I have some kind of PermissionSet object that the user carries around throughout the Web App in Session or whatever and the MVC Action method would check if that user can use that Action and then the View will have some ViewData or whatever where it checks the various permissions to do Hide/Show?

• Cygwin socket & thread & other programming issues (some question about Cygwin)

  - by SjB

  I have some question about cygwin : Can I use Cygwin develop socket based code? Does Cygwin have read() and write() functions that work with file descriptors? Can I use Pthread library in Cygwin? Does code that compiles in Cygwin also compile in Linux without any change or with little change? Will an executable file that built by Cygwin run in Linux ? Why does Cygwin not need the linker option -lpthread when I use pthread library? why in #include <iostream> don't I need to use using namespace std; ? Can I work with QT in Cygwin? If so, How?

  Hello everyone there, Me and my mates have been given an Excel spreasheet,which contains the data of the Census report. The column here corresponds to "Year" (from 2000-2010),the row means "City/Town",the cell is simply the population of a town at a particular year. We are up to doing some analysis like “what town had its first population gain in 10 years?” etc.My question is just about can we do this in Excel,or do we need to export the data to other database(SQL) then do the programming? Thanks in advance.

• Django URL regex question

  - by shawnjan

  Hey all! I had a quick question about Django URL configuration, and I guess REGEX as well. I have a small configuration application that takes in environments and artifacts in the following way: url(r'^env/(?P<env>\w+)/artifact/(?P<artifact>\w+)/$', 'config.views.ipview', name="bothlist"), Now, this works fine, but what I would like to do is have it be able to have additional parameters that are optional, such as a verbose mode or no formating mode. I know how to do this just fine in the views, but I can't wrap my head around the regex. the call would be something like GET /env/<env>/artifact/<artifact>/<opt:verbose>/<opt:noformat> Any help would be appreciated, thanks! -Shawn

• General Web Programming/designing Question: ?

  - by Prasad

  hi, I have been in web programming for 2 years (Self taught - a biology researcher by profession). I designed a small wiki with needed functionalities and a scientific RTE - ofcourse lot is expected. I used mootools framework and AJAX extensively. I was always curious when ever I saw the query strings passed from URL. Long encrypted query string directly getting passed to the server. Especially Google's design is such. I think this is the start of providing a Web Service to a client - I guess. Now, my question is : is this a special, highly professional, efficient / advanced web design technique to communicate queries via the URL ? I always felt that direct URL based communication is faster. I tried my bit and could send a query through the URL directly. here is the link: http://sgwiki.sdsc.edu/getSGMPage.php?8 By this , the client can directly link to the desired page instead of searching and / or can automate. There are many possibilities. The next request: Can I be pointed to such technique of web programming? oops: I am sorry, If I have not been able to convey my request clearly. Prasad.

• Excel and Tab Delimited Files Question

  - by OneNerd

  I am encountering what I believe to be a strange issue with Excel (in this case, Excel 2007, but maybe also Excel 2003, but don't have access to it as I write this). I can reliably convert some server data over into a tab-delimited format (been doing this for years) and then open it using Excel - no issue. However, what seems to be happening is if I have an html <table inside one of the fields, it looks like Excel 2007 thinks it should be converting the table into rows and columns inside Excel (not what I want). As you might imagine, this throws off the entire spreadsheet. So question is, is there any way to set up excel to NOT do this (perhaps some setting in Excel that pertains to reading tab delimited files), or am I missing something? Thanks.

• SQL Where question

  - by needshelp

  Hi all, I have a question about case statements and nulls in a where clause. I want to do the following: Declare @someVar int = null select column1 from TestTable t where t = case when @someVar is not null then @someVar else t end Here is the problem: Let's say @someVar is null. Let's also say that column1 from TestTable t has NULL column values. Then, my condition t = t in the case statement will always evaluate to false. I basically just want to be able to conditionally filter the column based on the value of @someVar if it's provided. Any help?

• algorithm analysis - orders of growth question

  - by cchampion

  I'm studing orders of growth "big oh", "big omega", and "big theta". Since I can't type the little symbols for these I will denote them as follows: ORDER = big oh OMEGA = big omega THETA = big theta For example I'll say n = ORDER(n^2) to mean that the function n is in the order of n^2 (n grows at most as fast n^2). Ok for the most part I understand these: n = ORDER(n^2) //n grows at most as fast as n^2 n^2 = OMEGA(n) //n^2 grows atleast as fast as n 8n^2 + 1000 = THETA(n^2) //same order of growth Ok here comes the example that confuses me: what is n(n+1) vs n^2 I realize that n(n+1) = n^2 + n; I would say it has the same order of growth as n^2; therefore I would say n(n+1) = THETA(n^2) but my question is, would it also be correct to say: n(n+1) = ORDER(n^2) please help because this is confusing to me. thanks.

• Question regarding Manifest in Java jar file

  - by Tara Singh

  Hi All, Is is mandatory to have classpath inside a Manifest file inside the java jar file? can we do work without having the classpath inside it? The reason why I am asking this is because I have a jar file for a server application. When I tried to connect many connections with Server, Server went down and the error was "Too many open files", when searched about it, I found one Sun Bug http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6446657 . Then I checked and i was having a classpath entry in the Jar file. So this question arises. Thanks, Tara Singh

• Efficiency Question for an Ajax App

  - by Kubi

  Hi, Currently I am dealing with a web application which uses a txt file as a database for testing for now. But we will connect it to a server later on. My question is, if there is a more efficient way to get my objects than the way I am using now. During the page_init I am getting all my objects into a Collection as List, then I am populating the ajax toolkit accordion objects in the page with that. I have some client side buttons which fires callbacks for getting some other objects to populate the accordions in an update panel. And I am using .net Collections too much like dictionary and list, I am wondering if using arrays is more efficient. Could you advise me about how to make this site better and faster ? Is it better or possible to initialize those TravelP objects in javascript at the beginning and use it like that ? Any comments would be greatly appreciated, Thanks

• Naming conventions and field naming question for CakePHP

  - by jphenow

  Okay so two questions very related: 1) Does following the naming convention for classes, controllers, database fields, etc. affect the framework's ability to work the way it was intended? (I'm a little new to working with a framework from the beginning of app development) 2) This question is more important if 1 is a yes. Say I have a table, A, that has 2 foreign keys pointing at the same table, B, but different entries (they're like edges of a graph that point at two vertices) how would I follow the naming convention of their database fields? All I can think to do is something like vertex_1_id and vertex_2_id but I don't know how the framework would handle that if the naming conventions are necessary for its functioning correctly.

• basic javascript question on geolocation and googlemaps

  - by ade

  hello all, Im hoping that somebody can help me out on what i feel is an easy answer but I just cant get it to work out. Im trying to trap the geolocation lat and long and place it into the google maps api so far i have var myOptions = { zoom:7, trips:1, mapTypeId: google.maps.MapTypeId.ROADMAP } var map = new google.maps.Map(document.getElementById("map"), myOptions); directionsDisplay.setMap(map); var request = { origin: 'newyork' destination: 'deleware', travelMode: google.maps.DirectionsTravelMode.DRIVING }; this works fine for what i want. how ever I want to be able to change Origin to the users lat long using the following script from google.maps.api. their code is: if(navigator.geolocation) { navigator.geolocation.getCurrentPosition(function(position) { initialLocation = new google.maps.LatLng(position.coords.latitude,position.coords.longitude); var placeMarker = new google.maps.Marker({ position: initialLocation, map: map, }); map.setCenter(initialLocation); }, function() { handleNoGeolocation(browserSupportFlag); }); } else { // Browser doesn't support Geolocation handleNoGeolocation(); } function handleNoGeolocation() { initialLocation = newyork; map.setCenter(initialLocation); } I want to pull out the navigator.geolocation.getCurrentPosition(function(position) { initialLocation = new google.maps.LatLng(position.coords.latitude,position.coords.longitude); and allocate it two 2 varibles, myLat and myLong. I then want to be able to change my orignal script from var request = { origin: 'newyork' destination: 'deleware', travelMode: google.maps.DirectionsTravelMode.DRIVING }; to var request = { origin: myLat,myLong destination: 'deleware', travelMode: google.maps.DirectionsTravelMode.DRIVING }; Does this make sense..? Im currently having a pig with it and as im not a JS developer its what i think should be a simple bit of coding that im losing the battle with.. any thoughts..?

• .Net MEF newbie question

  - by steve.macdonald

  I am missing something basic when it comes to using MEF. I got it working using samples and a simple console app where everything is in the same assembly. Then I put some imports and exports in a separate project which contains various entities. I want to use these entities in an MS Test, but the composition is never actually done. When I move the composition stuff into the constructor of an entity in question it works, but that's obviously wrong. Does GetExecutingAssembly only "see" the test process? What am I missing re containers? I tried putting the container in a Using in the test without luck. The MEF docs are still very scant and I can't find a simple example of an application (or MS Test) which uses entities from a different project...

• image analysis question for matlab

  - by raekwon

  Hi, I asked a similar question but wasn't quite clear before. I am trying to put a blue or an orange or some other colored circle (more like a donut) around a feature in an image so that I can track it. It should be more like a donut so that I can still view the image... Anyway, I have a multidimensional array and then extract 2D submatrices out of it and plot each one using imagesc(subarray). For all the subarrays there are multiple features that I've located and want to track. Is it possible in Matlab to put a donut/circle around them to do that? How would you do that?

• General question about DirectShow.NET, DirectShow and Windows Media Format

  - by Paul Andrews

  I searched and googled for an answer but couldn't find one. Basically I'm developing a webcam/audio streaming application which should capture audio and video from a pc (usb webcam/microphone) and send them to a receiving server. What the server will do with that it's another story and phase two (which I'm skipping for now) I wrote some code using DirectShow and Windows Media Format and it worked great for capture audio/video and sending them to another client, but there's a major problem: latency. Everywhere in the internet everyone gave me the same answer: "sorry dude but media format isn't for video conferencing, their codecs have too high latency". I thought I could skip the .wmv problems but seems like it's not possible to do... this road ends here then. So I saw a few examples with DirectShow.NET which were faster for both audio and video.. my question is: how come that DirectShow.NET is faster and better for video/audio conferencing? Shouldn't it be just a .NET porting of C++'s DirectShow? Am I missing something? I'm a bit confused at this point

• Hiring *good* Mobile Developers in/to Korea - overseas hiring question

  - by Jason

  Hello everyone. My question is regarding the best way to find a good mobile developer in Korea, or in another country to bring to Korea. Our company is growing fast and we need some quality mobile developers to start getting our system onto mobile. The problem is, however, that in Korea, their are very few mobile developers (currently) and their pay is extremely expensive. We have looked into India and other SE Asian countries and have concluded that bringing in a developer from another country may be the best choice. However, I am worried about how to find developers that are motivated by passion/creativity instead of getting a paycheck, and am also worried about what country may provide the higher quality worker. To clarify, we would bring in these workers from their country to Korea, and help them get settled here and working in our office. Has anyone had any experience doing this sort of thing in America/Korea/another country? Thank you very much for your replies.

• Question - Should I use SPItemReceiver or SPEmailEventReceiver

  - by RiverStorm

  Hello, I have custom SharePoint Document Library which I use to upload spreadsheet data into a database. When a spreadsheet is uploaded, the SPItemReceiver triggers, and upload the data. Now, I would like to add an incoming email feature to the document library. My question is...after the document library has received the spreadsheet by email. Should I use the override-able method EmailReceived of the SPEmailEventReceiver to process the data in the spreadsheet or still use the SPItemReceiver? I gather I could use either, but I would like to know your opinion which is better and why. Thanks in advance
