• Wrong values reported by pyPDF for various box regions

  - by romor

  Using pyPdf, for most files I get matched results concerning various box's dimensions compared to what Acrobat reports. However for some files I get different values reported by pyPdf and Acrobat, like: pyPdf: artBox: 595.3 x 841.9 bleedBox: 595.3 x 841.9 cropBox: 595.3 x 841.9 trimBox: 517.3 x 754 Acrobat: artBox: 439.35 x 666.13 pt bleedBox: 439.35 x 666.13 pt cropBox: 439.35 x 666.13 pt trimBox: 439.35 x 666.13 pt I thought it's units issue, but then ratio between widths and heights doesn't match also, not mentioning trimBox mismatch Correct results are those reported by Acrobat of course. Does someone know why is this and is there a way I get correct dimensions by using pyPdf? Thanks couple of minutes later... After reading this question: Are PDF box coordinates relative or absolute? I figured I didn't considered uper left corner to be different then 0 (zero). It turned out that box starts at 77.95 x 87.87, so if we reduce reported values of trimBox by this values correct result is obtained. artBox: 0 x 0 bleedBox: 0 x 0 cropBox: 0 x 0 trimBox: 77.95 x 87.87 Other boxes seem with misleading values or I misinterpret them. Snippet: from pyPdf import PdfFileReader pdfread = PdfFileReader(file('my.pdf', 'rb')) page = 1 width = pdfread.getPage(page).trimBox[2]-pdfread.getPage(page).trimBox[0] height = pdfread.getPage(page).trimBox[3] - pdfread.getPage(page).trimBox[1] print width, height

• Are local variables in Fortran 77 static or stack dynamic?

  - by mm2887

  For my programming languages class one hw problem asks: Are local variables in FORTRAN static or stack dynamic? Are local variables that are INITIALIZED to a default value static or stack dynamic? Show me some code with an explanation to back up your answer. Hint: The easiest way to check this is to have your program test the history sensitivity of a subprogram. Look at what happens when you initialize the local variable to a value and when you don’t. You may need to call more than one subprogram to lock in your answer with confidence. I wrote a few subroutines: - create a variable - print the variable - initialize the variable to a value - print the variable again Each successive call to the subroutine prints out the same random value for the variable when it is uninitialized and then it prints out the initialized value. What is this random value when the variable is uninitialized? Does this mean Fortran uses the same memory location for each call to the subroutine or it dynamically creates space and initializes the variable randomly? My second subroutine also creates a variable, but then calls the first subroutine. The result is the same except the random number printed of the uninitialized variable is different. I am very confused. Please help! Thank you so much.

• Can you have a Dynamic Data Field which consists of a list of fields?

  - by Telos

  This is a purely theoretical question (at least until I start trying to implement it) but here goes. I wrote a web form a long time ago which has a configurable section for getting information. Basically for some customers there are no fields, for other customers there are up to 20 fields. I got it working by dynamically creating the fields at just the right time in the page lifecycle and going through a lot of headaches. 2 years later, I need to make some pretty big updates to this web form and there are some nifty new technologies. I've worked with ASP.NET Dynamic Data just a bit and, well, I half-crazed plan just occurred to me: The Ticket object has a one-to-many relationship to ExtendedField, we'll call that relationship Fields for brevity. Using that, the idea would be to create a FieldTemplate that dynamically generated the list of fields and displayed it. The big questions here would probably be: 1) Can a single field template resolve to multiple web controls without breaking things? 2) Can dynamic data handle updating/inserting multiple rows in such a fashion? 3) There was a third question I had a few minutes ago, but coworkers interrupted me and I forgot. So now the third question is: what is the third question? So basically, does this sound like it could work or am I missing a better/more obvious solution?

• Is this a hole in dynamic binding in C# 4?

  - by Galilyou

  I've seen a very interesting post on Fabio Maulo's blog. Here's the code and the bug if you don't want to jump to the url. I defined a new generic class like so: public class TableStorageInitializer<TTableEntity> where TTableEntity : class, new() { public void Initialize() { InitializeInstance(new TTableEntity()); } public void InitializeInstance(dynamic entity) { entity.PartitionKey = Guid.NewGuid().ToString(); entity.RowKey = Guid.NewGuid().ToString(); } } Note that InitializeInstance accepts one parameter, which is of type dynamic. Now to test this class, I defined another class that is nested inside my main Program class like so: class Program { static void Main(string[] args) { TableStorageInitializer<MyClass> x = new TableStorageInitializer<MyClass>(); x.Initialize(); } private class MyClass { public string PartitionKey { get; set; } public string RowKey { get; set; } public DateTime Timestamp { get; set; } } } Note: the inner class "MyClass" is declared private. Now if i run this code I get a "Microsoft.CSharp.RuntimeBinder.RuntimeBinderException" on the line "entity.PartitionKey = Guide.NewGuid().ToString()". The interesting part, though is that the message of the exception says "Object doesn't contain a definition for PartitionKey". Also note that if you changed the modifier of the nested class to public, the code will execute with no problems. So what do you guys think is really happening under the hood? Please refer to any documentation -of course if this is documented anywhere- that you may find?

• Dynamic Select boxes page load

  - by Chris

  Hello, I have a dynamic chained select box that I am attempting to show the value of on a page load. In my chained select box, it will default to the first option within the select box on page load, could anyone provide assitance? I stumbled upon this thread, but I can't seem to translate what they are doing with that answer to my language of CF. Dynamic chained drop downs on page refresh Here is the JS script I am using. function dynamicSelect(id1, id2) { // Feature test to see if there is enough W3C DOM support if (document.getElementById && document.getElementsByTagName) { // Obtain references to both select boxes var sel1 = document.getElementById(id1); var sel2 = document.getElementById(id2); // Clone the dynamic select box var clone = sel2.cloneNode(true); // Obtain references to all cloned options var clonedOptions = clone.getElementsByTagName("option"); // Onload init: call a generic function to display the related options in the dynamic select box refreshDynamicSelectOptions(sel1, sel2, clonedOptions); // Onchange of the main select box: call a generic function to display the related options in the dynamic select box sel1.onchange = function() { refreshDynamicSelectOptions(sel1, sel2, clonedOptions); } } } function refreshDynamicSelectOptions(sel1, sel2, clonedOptions) { // Delete all options of the dynamic select box while (sel2.options.length) { sel2.remove(0); } // Create regular expression objects for "select" and the value of the selected option of the main select box as class names var pattern1 = /( |^)(select)( |$)/; var pattern2 = new RegExp("( |^)(" + sel1.options[sel1.selectedIndex].value + ")( |$)"); // Iterate through all cloned options for (var i = 0; i < clonedOptions.length; i++) { // If the classname of a cloned option either equals "select" or equals the value of the selected option of the main select box if (clonedOptions[i].className.match(pattern1) || clonedOptions[i].className.match(pattern2)) { // Clone the option from the hidden option pool and append it to the dynamic select box sel2.appendChild(clonedOptions[i].cloneNode(true)); } } } Thanks so much for any assistance

• Creating dynamic breadcrumb in asp.net mvc with mvcsitemap provider

  - by Jalpesh P. Vadgama

  I have done lots breadcrumb kind of things in normal asp.net web forms I was looking for same for asp.net mvc. After searching on internet I have found one great nuget package for mvpsite map provider which can be easily implemented via site map provider. So let’s check how its works. I have create a new MVC 3 web application called breadcrumb and now I am adding a reference of site map provider via nuget package like following. You can find more information about MVC sitemap provider on following URL. https://github.com/maartenba/MvcSiteMapProvid So once you add site map provider. You will find a Mvc.SiteMap file like following. And following is content of that file. <?xml version="1.0" encoding="utf-8" ?> <mvcSiteMap xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-3.0" xsi:schemaLocation="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-3.0 MvcSiteMapSchema.xsd" enableLocalization="true"> <mvcSiteMapNode title="Home" controller="Home" action="Index"> <mvcSiteMapNode title="About" controller="Home" action="About"/> </mvcSiteMapNode> </mvcSiteMap> So now we have added site map so now its time to make breadcrumb dynamic. So as we all know that with in the standard asp.net mvc template we have action link by default for Home and About like following. <div id="menucontainer"> <ul id="menu"> <li>@Html.ActionLink("Home", "Index", "Home")</li> <li>@Html.ActionLink("About", "About", "Home")</li> </ul> </div> Now I want to replace that with our sitemap provider and make it dynamic so I have added the following code. <div id="menucontainer"> @Html.MvcSiteMap().Menu(true) </div> That’s it. This is the magic code @Html.MvcSiteMap will dynamically create breadcrumb for you. Now let’s run this in browser. You can see that it has created breadcrumb dynamically without writing any action link code. So here you can see with MvcSiteMap provider we don’t have to write any code we just need to add menu syntax and rest it will do automatically. That’s it. Hope you liked it. Stay tuned for more till then happy programming.

• How can I locate empty space next to polygon regions?

  - by Stephen

  Let's say I have the following area in a top-down map: The circle is the player, the black square is an obstacle, and the grey polygons with red borders are walk-able areas that will be used as a navigation mesh for enemies. Obstacles and grey polygons are always convex. The grey regions were defined using an algorithm when the world was generated at runtime. Notice the little white column. I need to figure out where any empty space like this is, if at all, after the algorithm builds the grey regions, so that I can fill the space with another region. Basically what I'm hoping for is an algorithm that can detect empty space next to a polygon.

• What is the most simple implementation of IDynamicMetaObjectProvider?

  - by Néstor Sánchez A.

  Hi, I have this scenario... 1.- I'm providing a "Dynamic Table" for wich users can define Fields. Each Dynamic Table will have as many rows/records as needed, but the Field definitions are centralized. 2.- My Dynamic Row/Record class was inherited from the .NET DLR DynamicObject class, and the underlying storage was a List appropriately associated to the defining fields. Everything works fine! BUT... 3.- Because I need to Serialize the content, and DynamicObject is not Serializable, I was forced to generate and carry a Dynamic Object when dynamic member access is required. But this is ugly and redundant. So, I need to implement IDynamicMetaObjectProvider myself to achieve dynamic access and serialization together. After googling/binging unsuccessfully I ask for your help... Can anybody please give a good example (or related link) for doing that?

• Getting a linq table to be dynamically sent to a method

  - by Damian Spaulding

  I have a procedure: var Edit = (from R in Linq.Products where R.ID == RecordID select R).Single(); That I would like to make "Linq.Products" Dynamic. Something like: protected void Page_Load(object sender, EventArgs e) { something(Linq.Products); } public void something(Object MyObject) { System.Data.Linq.Table<Product> Dynamic = (System.Data.Linq.Table<Product>)MyObject; var Edit = (from R in Dynamic where R.ID == RecordID select R).Single(); My problem is that I my "something" method will not be able to know what table has been sent to it. so the static line: System.Data.Linq.Table Dynamic = (System.Data.Linq.Table)MyObject; Would have to reflect somthing like: System.Data.Linq.Table Dynamic = (System.Data.Linq.Table)MyObject; With being a dynamic catch all variable so that Linq can just execute the code just like I hand coded it statically. I have been pulling my hair out with this one. Please help.

• Domain registration and DNS, what am I actually paying for? [on hold]

  - by jozxyqk

  Long story short I'm quite confused as to exactly what is offered by domain registration and dns service sites. When I go to the url "http://google.com", my PC connects to a name server and gets the IP for "google.com", then connects to the IP and says, give me the page for "http://google.com". AFAIK there are many name servers and they all cache these bits of information in some hierarchical network, but ultimately a DNS record must come from a single source (not sure what this is called). There are different kinds of records, that might not an IP but an alias/redirect to other records for example. Lets say I want my own domain name for some server. Maybe it even has a static IP but I want a nicer thing for people to remember, or my ISP assigns dynamic IPs and I want a URL that always works, or my website is hosted on a shared machine so the browser needs to send "http://mydnsname.com" to the webserver to distinguish it from other requests to the same IP but for different sites. Registering a domain costs a small amount of money per year. Where does this money go, not that I'm complaining :P? Is that really all it costs to maintain the entire DNS system of nameservers? If I just register the domain and nothing else, what do I get? Is that just reserving a name or hosting WHOIS information or have I paid for a dns recrord to be hosted? Can a domain alone have a record, such as an IP or be an alias to another? A bunch of sites out there offer other services, in addition to domain registration (I'm assuming they register the domain through another party for me). One example is "dynamic DNS" (DDNS), but isn't this just a regular DNS record that's updated regularly? Does it cost extra to update more often? Without a DDNS, can a DNS record still point to an IP? I've also seen the term "managed DNS" and have no idea where that fits in.

• DirectX9 dynamic rendering

  - by gardian06

  What I am planning to do is have the models (or maybe just an identifier for the model to be used) stored outside of the directX9 framework, and so in nature have completely dynamic rendering. All of the information that I have found contains static rendering (rendering models that are stored in memory at specific positions) I would like information on how to take a model (or identifier for a model type) that is stored outside of the framework, and render it to the screen. I am expected to take a container that holds all the relevant data to be rendered. The information outside would hold the position, orientation (quaternion, though I am told that I can also get a rotation matrix if I prefer), and dimensions (scale)

• Dynamic Memory Allocation and Memory Management

  - by Bunkai.Satori

  In an average game, there are hundreds or maybe thousands of objects in the scene. Is it completely correct to allocate memory for all objects, including gun shots (bullets), dynamically via default new()? Should I create any memory pool for dynamic allocation, or is there no need to bother with this? What if the target platform are mobile devices? Is there a need for a memory manager in a mobile game, please? Thank you. Language Used: C++; Currently developed under Windows, but planned to be ported later.

• Create dynamic buffer SharpDX

  - by fedab

  I want to set a buffer that is updated every frame but can't figure it out, what i have to do. The only working thing i have is this: mdexcription = new BufferDescription(Matrix.SizeInBytes * Matrices.Length, ResourceUsage.Dynamic, BindFlags.VertexBuffer, CpuAccessFlags.Write, ResourceOptionFlags.None, 0); instanceBuffer = SharpDX.Direct3D11.Buffer.Create(Device, Matrices, mdexcription); vBB = new VertexBufferBinding(instanceBuffer, Matrix.SizeInBytes, 0); DeviceContext.InputAssembler.SetVertexBuffers(1, vBB); Draw: //Change Matrices (Matrix[]) every frame... instanceBuffer.Dispose(); instanceBuffer = SharpDX.Direct3D11.Buffer.Create(Device, Matrices, mdexcription); vBB = new VertexBufferBinding(instanceBuffer, Matrix.SizeInBytes, 0); DeviceContext.InputAssembler.SetVertexBuffers(1, vBB); I guess Dispose() and creating a new buffer is slow and can be done much faster. I've read about DataStream but i do not know, how to set this up properly. What steps do i have to do to set up a DataStream to achieve fast every-frame update?

• WPF more dynamic views and DataAnnotations

  - by Ingó Vals

  Comparing WPF and Asp.Net Razor/HtmlHelper I find WPF/Xaml to be somewhat lacking in creating views. With HtmlHelpers you could define in one place how you wan't to represent specific type of data and include elements set from the DataAnnotations of the property. In WPF you can also define DataTemplates for data but it seems much more limited then EditorTemplates. It doesn't use information from DataAnnotations. Also the layout of elements can be bothersome. I hate having to constantly add RowDefinitions and update the Grid.Row attribute of lot of elements when I add a new property somewhere in line. I understand that GUI programming can be a lot of grunt work like this but as Asp.Net MVC has shown there are ways around that. What solutions are out there to make view creation in WPF a little bit cleaner, maintainable and more dynamic?

• How to create a good sitemap for dynamic website

  - by Saif Bechan

  I have a website with dynamic content and different kind of pages. I have some pages that rarely change, and I have pages like blogs that change often. The blog pages also have links for sorting, for example sorting on date, asc, desc. On some of the pages I also have links to different tabbed content, and links that are just anchor links. Now when I use a xml sitemap generator then all the links are thrown into the site, and so I don't think all the links are really relevant. The blogposts up until now are also taken into the sitemap. Is this really necessary? I think the links to the blogposts can be indexed just fine. Is the best way to make a sitemap just to manually assign the main menu links to the sitemap, or is indexing everything really recommended?

• Best practice for managing dynamic HTML modules?

  - by jt0dd

  I've been building web apps that add and remove lots of dynamic content and even structure within the page, and I'm not impressed by the method I'm using to do it. When I want to add a section or module into a position in the interface, I'm storing the html in the code, and I don't like that: if (rank == "moderator") { $("#header").append('<div class="mod_controls">' + // content, using + to implement line breaks '</div>'); } This seems like such a bad programming practice.. There must be a better way. I thought of building a function to convert a JSON structure to html, but it seems like overkill. For the functionality of the apps I'm using: Node.js JS JQuery AJAX Is there some common way to store HTML modules externally for AJAX importation?

• Dynamic Dijkstra

  I need dynamic dijkstra algorithm that can update itself when edge's cost is changed without a full recalculation. Full recalculation is not an option. I've tryed to "brew" my own implemantion with no success. I've also tryed to find on the Internet but found nothing. A link to an article explaining the algorithm or even it's name will be good. Edit: Thanks everyone for answering. I managed to make algorithm of my own that runs in O(V+E) time, if anyone wishes to know the algorithm just say so and I will post it.

• deactivate dynamic contrast on dell xps

  - by Rock

  I am experiencing annoying automatic backlight brightness changes under ubuntu 12.04 LTS on my Dell XPS ultrabook. It seems to be connected to the amount of white pixels on the screen (switching back an forth between dark/light application windows makes the effect noticable, but also just scrolling through a website.) So I think it is the dynamic contrast feature of the notebook screen. How do I turn this off in Ubuntu? Windows offers specific Intel driver options for this, but I can't find any for Ubuntu. EDIT: Model: Dell XPS 14 Ultrabook and currently running Unity

• Dynamic tests with mstest and T4

  - by Victor Hurdugaci

  If you used mstest and NUnit you might be aware of the fact that the former doesn't support dynamic, data driven test cases. For example, the following scenario cannot be achieved with the out-of-box mstest: given a dataset, create distinct test cases for each entry in it, using a predefined generic test case. The best result that can be achieved using mstest is a single testcase that will iterate through the dataset. There is one disadvantage: if the test fails for one entry in the dataset, the whole test case fails. So, in order to overcome the previously mentioned limitation, I decided to create a text template that will generate the test cases for me. As an example, I will write some tests for an integer multiplication function that has 2 bugs in it: Read more >> [Cross post from victorhurdugaci.com]

• Dynamic Quad/Oct Trees

  - by KKlouzal

  I've recently discovered the power of Quadtrees and Octrees and their role in culling/LOD applications, however I've been pondering on the implementations for a Dynamic Quad/Oct Tree. Such tree would not require a complete rebuild when some of the underlying data changes (Vertex Data). Would it be possible to create such a tree? What would that look like? Could someone point me in the correct direction to get started? The application here would, in my scenario, be used for a dynamically changing spherical landscape with over 10,000,000 verticies. The use of Quad/Oct Trees is obvious for Culling & LOD as well as the benefits from not having to completely recompute the tree when the underlying data changes.

• How to reduce errors in dynamic language such as python, and improve my code quality

  - by Martin Luo

  I post the origin question in stackoverflow, some people suggest me to post here I've always have trouble with dynamic language like Python. Several problems: Typo error, I can use pylint to reduce some of these errors. But there's still some errors that pylint can not figure out. Object type error, I often forgot what type of the parameter is, int? str? some object? Also, forgot the type of some object in my code. Unit test might help me sometimes, but I'm not always have enough time to do UT. When I need a script to do a small job, the line of code are 100 - 200 lines, not big, but I don't have time to do the unit test, because I need to use the script as soon as possible. So, many errors appear. So, any idea on how to reduce the number of these problems?

• Hosting advice for a write-heavy dynamic website

  - by Rahul Rawat

  I have built a website using PHP and MySQL and now I am looking for a hosting service. I am expecting about a 1000 users registering and about 5-10k pageviews/day in a week's time. So which host should I opt for? It will let users submit contents of type blobs and submit around 10 pictures per users. I hope that traffic will increase so can justhost's or bluehost's shared hosting serve that purpose or should I go for more dedicated ones. Basically the site is write heavy and there are average 2-3 MySQL queries per page and it is quite dynamic. So depending on these requirements which web hosting will be optimal for me.
