• Foreach loop with 2d array of objects

  - by Jacob Millward

  I'm using a 2D array of objects to store data about tiles, or "blocks" in my gameworld. I initialise the array, fill it with data and then attempt to invoke the draw method of each object. foreach (Block block in blockList) { block.Draw(spriteBatch); } I end up with an exception being thrown "Object reference is not set to an instance of an object". What have I done wrong? EDIT: This is the code used to define the array Block[,] blockList; Then blockList = new Block[screenRectangle.Width, screenRectangle.Height]; // Fill with dummy data for (int x = 0; x <= screenRectangle.Width / texture.Width; x++) { for (int y = 0; y <= screenRectangle.Height / texture.Width; y++) { if (y >= screenRectangle.Height / (texture.Width*2)) { blockList[x, y] = new Block(1, new Rectangle(x * 16, y * 16, texture.Width, texture.Height), texture); } else { blockList[x, y] = new Block(0, new Rectangle(x * 16, y * 16, texture.Width, texture.Height), texture); } } }

• XSF-FO intellisense and national languages with Apache FOP

  - by Lukasz Kurylo

  Some time ago I showed how to get an intellisense and how to configure the FO.NET to acquire national characters inside the generated pdf files. Due to the limitations that I mensioned in my previous post, I started playing with the Apache FOP. In this post I want to show, how to acquire the same result as I showed in the two posts related to FO.NET.   Intellisense   To get the intellisense from the XSL-FO templates set the xsi:schemaLocation the same way I showed it in this post. The only diffrence to FO.NET is that, during generating the document by the code I showed last time we will get an exception:   org.apache.fop.fo.ValidationException: Invalid property encountered on "fo:root": xsi:schemaLocation (See position 6:11)   Fortunatelly there is a very easy way to resolve this without removing the entire attribute along with the intellisense. Add to the FopFactory the ignoreNamespace by:   FopFactory fopFactory = FopFactory.newInstance(); fopFactory.ignoreNamespace(http://www.w3.org/2001/XMLSchema-instance);   Notice that, the url specified in this method this is a namespace for the xmlns:xsi namespace, not xsi.schemaLocation.   Fonts / national characters   This point is a little dfferent to acquire, but not more complicated that it was with FO.NET. To set the fonts in Apache FOP 1.0, we need a configuration file. A sample one can be get from the directory where we unpacked the fop binaries, from conf subdirectory. There is a file called fop.xconf. We must copy this file to our solution. In the simplest way, in the <fonts> tag we can add  <auto-detect/>. Thanks to this, FOP will index all fonts available on the installed operating system. There probably should be no problem, if we have a http handler or a WCF Service on the server that serves the generated pdf documents. In this situation we can use all available fonts on this server.   To use this config file, we must set a path to it:   FopFactory fopFactory = FopFactory.newInstance(); fopFactory.setUserConfig(new File("fop.xconf"));

• Session serialization in JavaEE environment

  - by Ionut

  Please consider the following scenario: We are working on a JavaEE project for which the scalability starts to become an issue. Up until now, we were able to scale up but this is no longer an option. Therefore we need to consider scaling out and preparing the App for a clustered environment. Our main concern right now is serializing the user sessions. Sadly, we did not consider from the beginning the issue and we are encountering the following excetion: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: org.apache.catalina.session.StandardSessionFacade I did some research and this exception is thrown because there are objects stored on the session which does not implement the Serializable interface. Considering that all over the app there are quite a few custom objects which are stored on the session without implementing this interface, it would require a lot of tedious work and dedication to fix all these classes declaration. We will fix all this declarations but the main concern is that, in the future, there may be a developer which will add a non Serializable object on the session and break the session serialization & replication over multiple nodes. As a quick overview of the project, we are developing using a home grown framework based on Struts 1 with the Servlet 3.0 API. This means that at this point, we are using the standard session.getAttribute() and session.setAttribute() to work with the session and the session handling is scattered all over the code base. Besides updating the classes of the objects stored on session and making sure that they implement the Serializable interface, what other measures of precaution should we take in order to ensure a reliable Session replication capability on the Application layer? I know it is a little bit late to consider this but what would be the best practice in this case? Furthermore, are there any other issues we should consider regarding this transition? Thank you in advance!

• First Experience with Web Services

  When I first started programming with Microsoft .Net (1.0 Framework) I had a strong desire to learn how search engines indexed web sites. At that time I was a working as a search engine spammer creating web pages to generate traffic for specific themes for various clients. One way I attempted to better understand .Net was to build a web spider that analyzed web pages on demand. An example of the spider is hosted at AddLinkz.com. After my spider was built I had no real idea what I could/should do with it until I found the MSN Search API. I used this web service to compare its results with my spider. Additionally, I used the API to feed my .Net web spider new URLs from the API based on specific search terms. MSN’s search API was very easy to use, I just had to request information by calling a web URL with parameters via a Get request and the results were returned in XML. At that time all requests were limited to XML responses and a maximum of 1,000 results per query.   Since then the entire API has gone through several reconstructions, rebranding and new search services.  Microsoft’s new Bing API replaced the older MSN search API and added several new search capabilities. These new features allow search data to be returned for web searches, image searches, new searches, and related search terms to name a few. Bing API Version 2.0 SourceTypes Web Searches for web content Sushi Image Searches for images on the web Sushi News Searches news stories Sushi InstantAnswer Searches Encarta online what is sushi, convert 5 feet to meters, x*5=7, and 2 plus 2 Spell Searches Encarta dictionary for spelling suggestions Phonebook Searches phonebook entries sushi in Los Angeles RelatedSearch Returns the query strings most similar to yours Ad Returns advertisements to incorporate with results I currently plan to start using the web search feature from the new Bing 2.0 API in an open source project related to exception management. Currently, it is still in the conception phase.

• Oracle has some very helpful and free code...I think

  I found that some of the code that Oracle uses is very useful so I don't have to re-invent the wheel.

• Linking one uniform variable to many shaders

  - by Winged

  Let's say, that I have 3 programs, and in each of those programs there is a view matrix uniform, which should be the same in all those programs. Right now, when my camera moves, I need to re-upload the modified matrix to every program separately. Is it possible to create some kind of global uniforms which are constant for all programs linked to it, so I could just upload the matrix once? I tried creating a globalUniforms object which looked kinda like this: var globalUniforms = { program: {}, // (...) vMatrixUniform: null, // (...) initialize: function() { vMatrixUniform = gl.getUniformLocation(this.program, 'uVMatrix'); } }; So I could just link it to proper programs like this: program.vMatrixUniform = globalUniforms.vMatrixUniform;, and then pass the matrix like this: if (camera.isDirty.viewMatrix !== false) { camera.isDirty.viewMatrix = false; gl.uniformMatrix4fv(globalUniforms.vMatrixUniform, false, camera.viewMatrix.element); } but unfortunately it throws an error: Uncaught exception: gl.INVALID_VALUE was caused by call to: getUniformLocation called from line 272, column 2 in () in mysite/js/mesh.js: vMatrixUniform = gl.getUniformLocation(this.program, 'uVMatrix'); Summing up: is there a more efficient way of managing shaders which follows my logic?

• How to write constructors which might fail to properly instantiate an object

  - by whitman

  Sometimes you need to write a constructor which can fail. For instance, say I want to instantiate an object with a file path, something like obj = new Object("/home/user/foo_file") As long as the path points to an appropriate file everything's fine. But if the string is not a valid path things should break. But how? You could: 1. throw an exception 2. return null object (if your programming language allows constructors to return values) 3. return a valid object but with a flag indicating that its path wasn't set properly (ugh) 4. others? I assume that the "best practices" of various programming languages would implement this differently. For instance I think ObjC prefers (2). But (2) would be impossible to implement in C++ where constructors must have void as a return type. In that case I take it that (1) is used. In your programming language of choice can you show how you'd handle this problem and explain why?

• Delphi Client-Server Application using Firebird 2.5 error

  - by Japie Bosman

  I have got a lengthy question to ask. First of all Im still very new when it comes to Delphi programming and my experience has beem mostly developing small single user database applications using ADO and an Access database. I need to take the transition now to a client server application and this is where the problem starts. I decided to use Firebird 2.5 embeded as my database, as it is open source, and it is can be used with the interbase components in Delphi and that multiple clients can access the database simultanously. So I followed the interbase tutorial in Delphi. I managed to connect the client to the server and see the data in the example (While both are running on my pc), but when i tried to move the client to another pc, keeping the server on mine and running it to see if I can connect to the server it gave me the following error. Exception EIdSocketError in module clientDemo.exe at 0029DCAC. Socket Error # 10061 Connection refused. I understand that this might be because the host is defined as localhost in the client. But here is my first question. In the TSQLConncetion you can set die hostname under Driver-Hostname. The thing I want to know is how do you do this at run time, as I cannot get the property when I try and make an edit box to allow the user to enter the value and then set it via code like for example: SQLConncetion1.Driver.Hostname := edtHost.text; The thing is there is not such property to set, so how do you set the hostname at run time? Im using Delphi XE2 There is still a lot of questions to come especially when it comes to deployment, but I will take this piece by piece and I appreciate the advice.

• PerlRegEx vs RegularExpressionsCore Delphi Units

  - by Jan Goyvaerts

  The RegularExpressionsCore unit that is part of Delphi XE is based on the latest class-based PerlRegEx unit that I developed. Embarcadero only made a few changes to the unit. These changes are insignificant enough that code written for earlier versions of Delphi using the class-based PerlRegEx unit will work just the same with Delphi XE. The unit was renamed from PerlRegEx to RegularExpressionsCore. When migrating your code to Delphi XE, you can choose whether you want to use the new RegularExpressionsCore unit or continue using the PerlRegEx unit in your application. All you need to change is which unit you add to the uses clause in your own units. Indentation and line breaks in the code were changed to match the style used in the Delphi RTL and VCL code. This does not change the code, but makes it harder to diff the two units. Literal strings in the unit were separated into their own unit called RegularExpressionsConsts. These strings are only used for error messages that indicate bugs in your code. If your code uses TPerlRegEx correctly then the user should not see any of these strings. My code uses assertions to check for out of bounds parameters, while Embarcadero uses exceptions. Again, if you use TPerlRegEx correctly, you should never get any assertions or exceptions. The Compile method raises an exception if the regular expression is invalid in both my original TPerlRegEx component and Embarcadero’s version. If your code allows the user to provide the regular expression, you should explicitly call Compile and catch any exceptions it raises so you can tell the user there is a problem with the regular expression. Even with user-provided regular expressions, you shouldn’t get any other assertions or exceptions if your code is correct. Note that Embarcadero owns all the rights to their RegularExpressionsCore unit. Like all the other RTL and VCL units, this unit cannot be distributed by myself or anyone other than Embarcadero. I do retain the rights to my original PerlRegEx unit which I will continue to make available for those using older versions of Delphi.

• Why are my videos playing speeded up with no audio, but work fine if I log in as a guest?

  - by Martins Kruze

  Since the start of this week I have been experiencing a glitch in the multimedia on my Samsung R518 laptop. I have 2 problems: Videos in every player are speeded up around 2 or 4 times (including youtube.com (both HTML5 and flash variants), any other video on the web and videos on my laptop played by Totem Media Player), exception is VLC player, but 2nd problem does concern even that. There is no sound - simple as that (with or without headphones plugged in). These all problems are now, and has not seen before, I upgraded to Ubuntu 10.10 after it was possible, and from start I didn't have anything from this - it just started in this week. I haven't even putted new software in. I have more or less solved the question (kind of) - I just logged in as a guest - and it all works, but when I make a new user - it does not. Please help me.

• Calling COM from Intel Fortran?

  - by user57460

  I'm trying to get COM working from my Fortran application. I do a "COMINITIALIZE" followed by a "COMCreateObjectByProgID". Both of these appear to be successful and return a status of zero. However, when I try to use the COM object, I get "Unhandled exception at 0x00000000 in FortranProg01.exe: 0xC0000005: Access violation." I realize that this error can mean almost anything, but has anyone got some suggestions of common problems with COM that produce this problem? Here are some more details. My program code: program FortranProg01 use myolepg implicit none integer*4 comInitStatus integer:: comCreateStatus INTEGER(INT_PTR_KIND()) $OBJECT INTEGER(4) funcResult REAL(8) pkgVersion call COMINITIALIZE(comInitStatus) print *, comInitStatus call COMCreateObjectByProgID('MyOlePg.MyOlePkg', $OBJECT, comCreateStatus) print *, comCreateStatus funcResult = IMyOlePkg_GetPackageVersion($OBJECT, pkgVersion) print *, funcResult call COMUNINITIALIZE() end program FortranProg01 The wizard-generated interface code: INTERFACE !property PackageVersion INTEGER(4) FUNCTION IMyOlePkg_GetPackageVersion($OBJECT, pVal) INTEGER(INT_PTR_KIND()), INTENT(IN) :: $OBJECT !

• Checking preconditions or not

  - by Robert Dailey

  I've been wanting to find a solid answer to the question of whether or not to have runtime checks to validate input for the purposes of ensuring a client has stuck to their end of the agreement in design by contract. For example, consider a simple class constructor: class Foo { public: Foo( BarHandle bar ) { FooHandle handle = GetFooHandle( bar ); if( handle == NULL ) { throw std::exception( "invalid FooHandle" ); } } }; I would argue in this case that a user should not attempt to construct a Foo without a valid BarHandle. It doesn't seem right to verify that bar is valid inside of Foo's constructor. If I simply document that Foo's constructor requires a valid BarHandle, isn't that enough? Is this a proper way to enforce my precondition in design by contract? So far, everything I've read has mixed opinions on this. It seems like 50% of people would say to verify that bar is valid, the other 50% would say that I shouldn't do it, for example consider a case where the user verifies their BarHandle is correct, but a second (and unnecessary) check is also being done inside of Foo's constructor.

• What reasons are there to reduce the max-age of a logo to just 8 days? [closed]

  - by callum

  Most websites set max-age=31536000 (1 year) on the Cache-control headers of static assets such as logo images. Examples: YouTube Yahoo Twitter BBC But there is a notable exception: Google's logo has max-age=691200 (8 days). I've checked the headers on the Google logo in the past, and it definitely used to be 1 year. (Also, it used to be part of a sprite, and now it is a standalone logo image, but that's probably another question...) What could be valid technical reasons why they would want to reduce its cache lifetime to just 8 days? Google's homepage is one of the most carefully optimised pages in the world, so I imagine there's a good reason. Edit: Please make sure you understand these points before answering: Nobody uses short max-age lifetimes to allow modifying a static asset in future. When you modify it, you just serve it at a different URL. So no, it's nothing to do with Google doodles. Think about it: even if Google didn't understand this basic trick of HTTP, 8 days still wouldn't be appropriate, as only those users who don't have the original logo cached would see the doodle on doodle-day – and then that group of users would go on seeing the doodle for the following 8 days after Google changed it back :) Web servers do not worry about "filling up" the caches of clients (or proxies). The client manages this by itself – when it hits its own storage limit, it just starts dropping the lowest priority items to make space for new items. The priority score is based on the question "How likely am I to benefit from having cached this URL?", which is nothing to do with what max-age value the server sent when the URL was originally requested; it's a heuristic based on the "frecency" of requests for that URL. The max-age simply lets the server set a cut-off point – the time at which the client is supposed to discard the item regardless of how often it's being re-used. It would be very nice and trusting of a downstream client/proxy to rely on all origin servers "holding back" from filling up their caches, but I don't think we live in that world ;)

• I don't understand the definition of side effects

  - by Chris Okyen

  I don't understand the wikipedia article on Side Effects: In computer science, a function or expression is said to have a side effect if, in addition to returning a value, it also 1.) Modifies some state or 2.) Has an observable interaction with calling functions or the outside world. I know an example of the first thing that causes a function or expression to have side effects - modifying a state Function and Expression modifying a state : 1.) foo(int X) { return x = x % x; } a = a + 1; What does 2.) - Has an observable interaction with calling functions or the outside world," mean? - Please give an example. The article continues on to say, "For example, a function might modify a global or static variable, modify one of its arguments, raise an exception, write data to a display or file, read data, or call other side-effecting functions...." Are all these examples, examples of 1.) - Modifiying some state , or are they also part of 2.) - Has an observable interaction with calling functions or the outside world?

• "Viral" license that only blocks legal actions of user and developer against each other

  - by Lukasz Zaroda

  I was thinking a lot about software licensing lately, because I would like to do some coding. I'm not an expert in all those licenses, so I came up with my own idea, and before I will put in on paper, I would like to make sure that I didn't reinvent a wheel, so maybe I would be able to use something that exists. Main idea behind my license is to guarantee freedom of use the software, but not "freedom to" (positive) (e.g. freedom to having source code), but "freedom from" (negative) (strictly from legal actions against you). It would be "viral" copyleft license. You would be able to without fear do everything you want with the software (and binaries e.g. reverse engineering), as long as You will include information about author and/or authors, and all derivative works will be distributed with the same license. I'm not interested in anything that would restrict a freedom of company to do something like "tivoization". I'm just trying to accomplish something that would block any legal actions of user and developer, targeted against each other, with the exception of basic attribution. Does exist something like that?

• Alternatives to Pessimistic Locking in Cluster Applications

  - by amphibient

  I am researching alternatives to database-level pessimistic locking to achieve transaction isolation in a cluster of Java applications going against the same database. Synchronizing concurrent access in the application tier is clearly not a solution in the present configuration because the same database transaction can be invoked from multiple JVMs concurrently. Currently, we are subject to occasional race conditions which, due to the optimistic locking we have in place via Hibernate, cause a StaleObjectStateException exception and data loss. I have a moderately large transaction within the scope of my refactoring project. Let's describe it as updating one top-level table row and then making various related inserts and/or updates to several of its child entities. I would like to insure exclusive access to the top-level table row and all of the children to be affected but I would like to stay away from pessimistic locking at the database level for performance reasons mostly. We use Hibernate for ORM. Does it make sense to start a single (perhaps synchronous) message queue application into which this method could be moved to insure synchronized access as opposed to each cluster node using its own, which is a clear race condition hazard? I am mentioning this approach even though I am not confident in it because both the top-level table row and its children could also be updated from other system calls, not just the mentioned transaction. So I am seeking to design a solution where the top-level table row and its children will all somehow be pseudo-locked (exclusive transaction isolation) but at the application and not the database level. I am open to ideas and suggestions, I understand this is not a very cut and dried challenge.

• Using local repository with vmbuilder and https

  I seem to be having problems using vmbuilder with a local https mirror "--mirror=https:///archive.ubuntu.com/ubuntu/" as shown below: Process (['/usr/sbin/debootstrap', '--arch=amd64', 'precise', '/tmp/tmpYc0cOktmpfs', '<my_internal_server>/ubuntu/']) returned 1. stdout: I: Retrieving Release E: Failed getting release file <my_internal_server>/ubuntu/dists/precise/Release , stderr: 2012-10-18 10:36:36,429 INFO : Unmounting tmpfs from /tmp/tmpYc0cOktmpfs Traceback (most recent call last): File "/usr/bin/vmbuilder", line 24, in <module> cli.main() File "/usr/lib/python2.7/dist-packages/VMBuilder/contrib/cli.py", line 216, in main distro.build_chroot() File "/usr/lib/python2.7/dist-packages/VMBuilder/distro.py", line 83, in build_chroot self.call_hooks('bootstrap') File "/usr/lib/python2.7/dist-packages/VMBuilder/distro.py", line 67, in call_hooks call_hooks(self, *args, **kwargs) File "/usr/lib/python2.7/dist-packages/VMBuilder/util.py", line 165, in call_hooks getattr(context, func, log_no_such_method)(*args, **kwargs) File "/usr/lib/python2.7/dist-packages/VMBuilder/plugins/ubuntu/distro.py", line 136, in bootstrap self.suite.debootstrap() File "/usr/lib/python2.7/dist-packages/VMBuilder/plugins/ubuntu/dapper.py", line 269, in debootstrap run_cmd(*cmd, **kwargs) File "/usr/lib/python2.7/dist-packages/VMBuilder/util.py", line 120, in run_cmd raise VMBuilderException, "Process (%s) returned %d. stdout: %s, stderr: %s" % (args.__repr__(), status, mystdout.buf, mystderr.buf) VMBuilder.exception.VMBuilderException: Process (['/usr/sbin/debootstrap', '--arch=amd64', 'precise', '/tmp/tmpYc0cOktmpfs', '<my_internal_server>/ubuntu/']) returned 1. stdout: I: Retrieving Release E: Failed getting release file <my_internal_server>/ubuntu/dists/precise/Release , stderr: I've checked that the files are in the correct place and i'm able to setup this using http instead of https. However this server will be providing https access only to the repos, the http is only temporarily open. This might be due to the certificate not being valid on the https (since it's self signed) or due to the fact that vmbuilder doesn't support https? In either case how can i get this to work? (If it's the case of the invalid certificate I don't mind ignoring any checks)

• How can I improve my isometric tile-picking algorithm?

  - by Cypher

  I've spent the last few days researching isometric tile-picking algorithms (converting screen-coordinates to tile-coordinates), and have obviously found a lot of the math beyond my grasp. I have come fairly close and what I have is workable, but I would like to improve on this algorithm as it's a little off and seems to pick down and to the right of the mouse pointer. I've uploaded a video to help visualize the current implementation: http://youtu.be/EqwWcq1zuaM My isometric rendering algorithm is based on what is found at this stackoverflow question's answer, with the exception that my x and y axis' are inverted (x increased down-right, while y increased up-right). Here is where I am converting from screen to tiles: // these next few lines convert the mouse pointer position from screen // coordinates to tile-grid coordinates. cameraOffset captures the current // mouse location and takes into consideration the camera's position on screen. System.Drawing.Point cameraOffset = new System.Drawing.Point( 0, 0 ); cameraOffset.X = mouseLocation.X + (int)camera.Left; cameraOffset.Y = ( mouseLocation.Y + (int)camera.Top ); // the camera-aware mouse coordinates are then further converted in an attempt // to select only the "tile" portion of the grid tiles, instead of the entire // rectangle. this algorithm gets close, but could use improvement. mouseTileLocation.X = ( cameraOffset.X + 2 * cameraOffset.Y ) / Global.TileWidth; mouseTileLocation.Y = -( ( 2 * cameraOffset.Y - cameraOffset.X ) / Global.TileWidth ); Things to make note of: mouseLocation is a System.Drawing.Point that represents the screen coordinates of the mouse pointer. cameraOffset is the screen position of the mouse pointer that includes the position of the game camera. mouseTileLocation is a System.Drawing.Point that is supposed to represent the tile coordinates of the mouse pointer. If you check out the above link to youtube, you'll notice that the picking algorithm is off a bit. How can I improve on this?

• WCF - Automatically create ServiceHost for multiple services

  - by Rajesh Pillai

  WCF - Automatically create ServiceHost for multiple services Welcome back readers!  This blog post is about a small tip that may make working with WCF servicehost a bit easier, if you have lots of services and you need to quickly host them for testing. Recently I was encountered a situation where we were faced to create multiple service host quickly for testing.  Here is the code snippet which is pretty self explanatory.  You can put this code in your service host which in this case is  a console application. class Program   {       static void Main(string[] args)       { // Stores all hosts           List<ServiceHost> hosts = new List<ServiceHost>();           try           { // Get the services element from the serviceModel element in the config file               var section = ConfigurationManager.GetSection("system.serviceModel/services") as ServicesSection;               if (section != null)               {                   foreach (ServiceElement element in section.Services)                   { // NOTE : If the assembly is in another namespace, provide a fully qualified name here in the form // <typename, namespace> // For e.g. Business.Services.CustomerService, Business.Services                       var serviceType = Type.GetType(element.Name); // Get the typeName                        var host = new ServiceHost(serviceType);                       hosts.Add(host); // Add to the host collection                       host.Open(); // Open the host                   }               }               Console.ReadLine();           }           catch (Exception e)           {               Console.WriteLine(e.Message);               Console.ReadLine();           }           finally           {               foreach (ServiceHost host in hosts)               {                   if (host.State == CommunicationState.Opened)                   {                       host.Close();                   }                   else                   {                       host.Abort();                   }               }           }       }   } I hope you find this useful.  You can make this as a windows service if required.

• CA For A Large Intranet

  - by Tim Post

  I'm managing what has become a very large intranet (over 100 different hosts / services) and will be stepping down from my role in the near future. I want to make things easy for the next victim person who takes my place. All hosts are secured via SSL. This includes various portals, wikis, data entry systems, HR systems and other sensitive things. We're using self signed certificates which worked o.k. in the past, but are now problematic because: Browsers make it harder for users to understand exactly what is going on when a self signed certificate is encountered, much less accept them. Putting up a new host means 100 phone calls asking what "Add an exception" means What we were doing is just importing the self signed certs when we set up a new workstation. This was fine when we only had a dozen to deal with, but now its just overwhelming. Our I.T. Department has classified this as ya all's problem, all we get from them is support for switch and router configurations. Beyond the user having connectivity, everything else is up to the intranet administrators. We have a mix of Ubuntu and Windows workstations. We'd like to set up our own self signed CA root, which can sign certificates for each host that we deploy on the intranet. Client browsers would of course be told to trust our CA. My question is, would this be dangerous and would we be better off going with intermediate certificates from someone like Verisign? Either way, I still have to import the root for the intermediate CA, so I really don't see what the difference is? Other than charging us money, what would Verisign be doing that we could not, beyond protecting the root CA cert so it can't be used to make forgeries?
