• Windows ACL inheritance issues for FTP server and automated tools

  - by Martin Sall

  I have set up Cerberus FTP server. By default, Cerberus FTP service runs under SYSTEM ACCOUNT. Also I have some console applications which run as scheduled tasks. They are running under a dedicated "Utilities" user account which has "Log on as batch job" permissions. These console applications take uploaded FTP files, process them and then move them to some dedicated archive folder. The problem is that my console apps are throwing Security exceptions when trying to acces the uploaded files. I tried to give the Full control permissions on the ftproot folder for my "Utilities" account and I have checked that "Replace all Child object permissions with inheritable permissions from this object" checkbox, but it affects only current files. When new files are uploaded, they again are not accessible by my "Utilities" account. I tried to go another way and put Cerberus FTP service under "Utilities" account. Then I also needed to give "Utilities" account permissions on Cerberus Data folder in ProgramData. Still no luck - after this operation, Cerberus internal SOAP web service stopped working (although everything else seems to work). I need that SOAP service to be available, so running the Cerberus FTP under "Utilities" account seems to be not an option. Unless I find out, what else do I need to set up for that "Utilities" account to stop Cerberus from complaining. I guess, Cerberus is uploading files to some temporary folder and so those files get the permissions form that folder and keep the same permissions even after moved to the ftproot. What would be the right solution for this which would grant Cerberus FTP server and the "Utilities" account minimal needed permissions to access the contents of the ftproot folder?

• SQuirreL Client: Opening up a table in a separate tab

  - by Dalin Seivewright

  I've switched to SQuirrel Client to view an Oracle database with a variety of tables. At any given time, I need to look at the contents of several related tables at the same time. The problem is that, at least by default, SQuirrel Client does not open up multiple tables at a time. When you click on a different Table object, the main view is refreshed with newly selected table data. Oracle's SQLDeveloper (which I am trying to move away from) did this by default if I recall, but there was an option to "freeze" panes. Does a similar option exist in SQuirrel Client? I do not require the ability to view the contents of two different tables on the same screen (i.e. a split view) but I would like the ability to have tabs for each table so I can quickly switch between each table view rather then having to find the table in the table list over and over again. Note: I am using this in a professional capacity but if it does not "belong" here then I suppose it could be moved to superuser.

• How do I apply 2 rotations about different points to a single primitive using OpenGL

  - by Fenoec

  I'm working on a 2D top-down shooter game that has a rotation feature like Realm Of The Mad God such that if you press e the camera rotates around the character in a clockwise direction and q rotates the camera around the character in a counterclockwise direction. I have this working with my floors and walls by translating to the character, doing the screen rotation, and drawing everything with the character as the origin. The problem arises when I shoot projectiles which need to both rotate around the character and rotate around themselves (shooting uses the mouse cursor so I can shoot at any angle). For example, if the screen is not rotated and I'm shooting rectangular projectiles, I want them to face in the direction I'm shooting (rotation around themselves). However if I only do this rotation, when I then rotate the screen the projectiles will always shoot at the same position because my cursor position does not change. Therefore I need to also either rotate the projectiles around the character or rotate the mouse cursor position to get the correct position (which would then totally screw up all of the collision detection). Likewise if I only do the screen rotation on projectiles, the rectangles will always be facing the same way and they would only look correct if I were shooting straight up or straight down. So my question is, how can I perform 2 rotations on a primitive around 2 different points? The only way I can think of is to translate to the character and do the screen rotation, then somehow calculate the translation required to move back to the middle of the projectile (seeing as how my axes are now rotated) and do its rotation. Or am I thinking about this in the wrong way and there is a different solution to accomplishing this effect?

• Multiple Java EE Agents on Single Managed Server

  - by tina.wang

  A default JEE agent is created when you create domain, which is named as OracleDIAgent. 1. In Studio, duplicate the agent, change its name to genAgent, change the web application context to genagent. 2: Go to datasource of genAgent, drop all datasources.3: Generate server template. put the jar file under odi\common\templates\wls 4: Deploy this template by update the existing domain. Bring up the config.cmd, choose update existing domain. 5: Update the domain using the template that just generated. Go through the Configuration wizard. (I did not modify anything or configure anything here). 6: The wizard will give information says the deployment was successful. 7: Bring up the admin server and ODI_server1.

• All in a Day's Work: Unblocking Multiple Downloaded Files with a Single Command

  - by Sam Abraham

  Files downloaded using Internet Explorer retain Internet Zone permission level and hence are “Blocked” by default on Windows 7 machines. Honestly, while an added overhead for developers; I really appreciate this feature as it provides a good protection layer for casual web users. My workaround is to simply unblock the downloaded zip file (if download was a zip file) which, in turn, unblocks the files stored within. Today however, I was left with a situation where I had to “Open” and “Copy” the content rather than “Save” a zip file. That of course left me with a few dozen files I have to manually unblock. A few minutes of internet search lead me to the link below which worked like a charm: 1-Download streams.exe from SystInternals - http://technet.microsoft.com/en-us/sysinternals/bb897440.aspx 2-Go to command prompt (cmd.exe) 3-Navigate to where you have streams.exe installed 4-Use command line switches: streams.exe –s –d “<folder path>” This removed the Internet Zone restrictions from all files under “<folder path>” and its subfolders as well. [Deleted :Zone.Identifier:$DATA] References: http://social.technet.microsoft.com/Forums/en-US/itproxpsp/thread/806f0104-1caa-4a66-b504-7a681d1ccb33/

• Disabling IPv6 on a single interface

  - by ijw

  I'm slightly weirded out by the fact that Ubuntu won't process ipv4 DHCP unless you explicitly tell it to, but will happily take ipv6 RAs unless you tell it not to. Is there any way to change the default behaviour to be 'do nothing unless I explicitly turn it on'? (Note to answerers: I'm not looking to globally disable ipv6, or completely turn off autoconf. I'm looking to disable autoconf by default (as in, I don't want ipv6 unless I say so in /etc/network/interfaces, in the same way that I don't just get a v4 address unless I've explicitly turned on dhcp). What's happening is that, for any interface that's up - e.g. has an ipv4 config - a v6 address tends to just turn up on the interface as well, despite the fact that I've not enabled that explicitly. The solutions to date are fine as far as they go, but if I disable v6 or autoconf globally, I can't then re-enable v6 on a per-interface basis with a simple command in /etc/network/interfaces. I'm fairly sure I'm asking for the moon on a stick, mind you.)

• ASP.NET MVVM Handling multiple Data Transfer Objects on a single page

  - by meffect

  I have an asp.net mvc "edit" page which allows the user to make edits to the parent entity, and then also "create" child entities on the same page. Note: I'm making these data transfer objects up. public class CustomerViewModel { public int Id { get; set; } public Byte[] Timestamp { get; set; } public string CustomerName { get; set; } public etc.. public CustomerOrderCreateViewModel CustomerOrderCreateViewModel { get; set; } } In my view I have two html form's. One for Customer "edit" Http Posts, and the other for CustomerOrder "create" Http Posts. In the view page, I load the CustomerOrder "create" form in using: <div id="CustomerOrderCreate"> @Html.Partial("Vendor/_CustomerOrderCreatePartial", Model.CustomerOrderCreateViewModel) </div> The CustomerOrder html form action posts to a different controller HttpPost ActionResult than the Customer "edit" Action Result. My concern is this, on the CustomerOrder controller, in the HttpPost ActionResult [HttpPost] public ActionResult Create(CustomerOrderCreateViewModel vm) { if (!ModelState.IsValid) { return [What Do I Return Here] } ...[Persist to database code]... } I don't know what to return if the model state isn't valid. Right now it's not a problem, because jquery unobtrusive validation handles validation on the client. But what if I need more complex validation (ie: the server needs to handle the validation).

• A Virtual Seat at the Architect&rsquo;s Table

  - by Bob Rhubart

  I always have fun producing the Arch2Arch podcasts, but the latest batch was all that and a bag of chips, since I was required to do absolutely no preparation and very little talking, and since the conversation was reminiscent of those I’ve had with various architects (you know who you are) in various watering holes: free-ranging, extemporaneous, and far, far from dull. The three most recent programs were recorded during a virtual mini meet-up of architects back in February.  You’ll find more detail here, but in a nutshell, I invited several previous Arch2Arch panelists to join me on Skype to talk about whatever was on their minds.  The resulting conversation yielded the three latest programs. Check them out – it’s like you’re sitting at the table. Listen to Part 1 Listen to Part 2 Listen to Part 3 The conversation begins with the participant’s responses to my challenge to fill in the blank in the sentence “Most conversations about Enterprise Architecture are too ____.” From there the conversation morphed into a discussion of the sheer joy of finding funding for architecture projects. The architects seated at the virtual table in these programs are:  Todd Biske, a veteran enterprise architect and the author of the book SOA Governace, from Packt Publishing. ( LinkedIn | Twitter | Blog | Oracle Mix ) Jordan Braunstein, an Oracle ACE Director and the Business Integration and Architecture Partner at TUSC. (Blog | Twitter | LinkedIn | Oracle Mix) Basheer Khan,  also an Oracle ACE Director, and the founder and CEO of Innowave Technology (Blog | LinkedIn | Twitter | Oracle Mix) Pat Shepherd, an enterprise architect with the Oracle Enterprise Solutions Group. (Oracle Mix | LinkedIn | Blog) Coming Soon I was so pleased with the results of this meet-up format that I did the same thing for the next series of programs.  These free-ranging conversations feature a different group of participants, covering a different set topics, including the fear of SOA, the misunderstanding and misinformation behind that fear, and the idea of beauty in architecture. Yeah, you read that right. So stay tuned: RSS   Technorati Tags: oracle,otn,enterprise architecture,podcast. arch2arch,meet-up del.icio.us Tags: oracle,otn,enterprise architecture,podcast. arch2arch,meet-up

• Organizing single page code well with Notepad++

  - by Hudson

  I've a c# file that will contain, most likely 10,000+ lines of code. I'd like to break this file into tabbed segments, so I can organize each method into a certain tab and label the tab something like : initial setup, helper functions,execution logic,list structures,global variables, etc. If I were using PHP I would have separate files and use include(); to include the separate files. What can be done, following the same style, with c#?

• Single-Click Checkbox in RadGridView

  - by Anthony Trudeau

  Originally posted on: http://geekswithblogs.net/tonyt/archive/2014/06/05/156809.aspxThe Telerik RadGridView for WPF is a flexible visual control for displaying and manipulating tables of data. It’s not without it’s quirks though. I ran into one of those quirks recently. The behavior of the RadGridView requires that you first activate the cell for editing. That enables the editing controls underneath. Although that provides better editing capabilities, it also can be unintuitive. In my case I don’t want my users to have to click a checkbox value twice in order to change the value. This can be solved easily by setting the EditTriggers and AutoSelectOnEdit properties to CellClick and True respectively. Unfortunately, the story doesn’t end there. You would think you could set those properties in a style with a TargetType of GridViewCheckBoxColumn. You’d be wrong. <!-- This works --> <telerik:GridViewCheckBoxColumn Header="Flag #1"       DataMemberBinding="{Binding Flag1}"       EditTriggers="CellClick" AutoSelectOnEdit="True"/> <!-- This doesn’t work --> <Style TargetType="{x:Type telerik:GridViewCheckBoxColumn}">       <Setter Property="EditTriggers" Value="CellClick" />       <Setter Property="AutoSelectOnEdit" Value="True" /> </Style> Telerik told me that is the correct, expected behavior, because the columns in the RadGridView are not visual elements. Their explanation is that the Style property comes from the base class FrameworkContentElement, but the column objects aren’t visual elements. That may be an implementation truth, but that doesn’t make the behavior correct or expected. It’s unintuitive that the GridViewCheckBoxColumn exposes a Style property that cannot be used properly, but there it is. At least there’s a way to get the desired effect.

• How does a single programmer make a game?

  - by Mike

  I have always been a software developer, but lately I've been wanting to get into games. The only thing stopping me is the fact that I'm a programmer, not an artist. I've made some simple stuff, Tetris, 2D chess things like that but I can't do much art and that's really what holds me back. Now the problem is, I've yet to go to college so most commercial projects wouldn't accept me even to work for free and learn a bit especially with my lack of experience in games and any indie projects I've looked into really have an issue with responding to people interested, or actually completing (or starting really, most don't get past the ideas on paper) the project they want to do. I've looked around locally for artists, anyone who can do modeling, textures or animating or even anyone with some ability to make some more advanced 2D assets to get something like a side-scrolling RPG or something but haven't been able to find anyone. So how do you guys do it? Do I really just have to wait until I can go to college to see if I like working with games or is there some way I can get art (for free, anything I do is just going to be for fun so I don't want to have to sink money into it) and just start messing around on my own? Or am I just having bad luck and not looking in the right places for other people interested in having me help? I'm not looking for anything in particular, just something to fill some time with and see if I like making games. If not, well I'll go back to my software projects. I just have one more year of highschool and I'd like to try a few different areas before I go to college.

• Complex shading using one single (small) texture

  - by teodron

  Recently I stumbled upon a demo reel in UDK about how one can attain beautiful results using just one (rather tiny) texture that's being sent to the shader pipeline. The famous link is this one. Basically, the author states that they've used just one texture and give a snapshot of the technique here. I see that every RGBA channel contains different grayscale information.. and that info could be used to inside a shader to obtain a colour blended output. The problem is that the reel displays a fairly complex scene. To top that, the author even makes use of a normal map. How did they manage to fit a normal map in an already cluttered texture? It makes sense to have a half-space normal map by using only RG from an RGB texture, but what about the rest of the information? Since it was proven to be possible, could someone please explain how it was done (the big picture, not the dirty details!)!? Here's the texture being used. Click to see in full size.

• Take a single snaphot from a webcam with a delay

  - by cedivad

  I use gst-launch-0.10 v4l2src num-buffers=1 ! jpegenc ! filesink location=$HOME/Desktop/test.jpg to take snapshots. It works well. However in some light situation I need to drop some of the first frames the webcam outputs so that the webcam white balance doesn't provide me with an impossible to view image. Do you know how could I do that? With the GUI of cheese I can do it without any problem, but I need to automate this via CLI. Many thanks.

• Term for a single C++ endpoint/object file

  - by Qix

  I have heard several terms for a C++ "Codepoint" (which is what I've heard used the most often), or a .cpp file that is compiled into an object file. For instance, .cpp files can include other .cpp files (or any other file, really, so long as it compiles), but during compilation, there is really only one 'main' code file that is used/generated. I know there is a widely accepted term, I just can't recall what it is. What is the accepted term for the final .c/.cpp file used to generate an object file?

• Can a website become popular in a "category" (ie, not just a single page)

  - by Earlz

  I have a few keywords where my website is high ranking(2nd and 3rd result). For instance, I have 3 blog posts covering a certain kind of modem. Is it common for search engines to consider a website popular in a "category"? For instance, if I was the first result for "foobar" with one page, and then added another separate page which mentioned "foobar"(and maybe a link from the original page), would a search engine prioritize this separate page when compared to a completely separate website with a page with the same content?

• Single Responsibility Principle: Responsibility unknown

  - by lurkerbelow

  I store sessions in a SessionManager. The session manager has a dependency to ISessionPersister. SessionManager private readonly ISessionPersister sessionPersister; public SessionManager(ISessionPersister sessionPersister) { this.sessionPersister = sessionPersister; } ISessionPersister public interface ISessionPersister : IDisposable { void PersistSessions(Dictionary<string, ISession> sessions); } Q: If my application shuts down how / where do I call PersistSessions? Who is responsible? First Approach: Use Dispose in SessionManager protected virtual void Dispose(bool disposing) { if (disposing) { if (this.sessionPersister != null && this.sessionMap != null && this.sessionMap.Count > 0) { this.sessionPersister.PersistSessions(this.sessionMap); } } } Is that the way to go or are there any better solutions?

• Using Single Image for Map in 2D Platformer

  - by Jon

  I'm fairly new to game development, and have been messing around with Slick2D. Currently, my map consists of objects that are represented as rectangles. If I wanted to use am image simlar to: How would I be able to use this image to make a level? That question is a bit vague, but like I said, I'm new to game development and am not familiar with terminology or procedures. But going along with this question, how would I also use non-rectangular objects/platforms? Thanks

• Using gerrit (or similar tool) on a team where multiple devs work on a single feature

  - by Bacon

  We have a team of roughly ~8 devs who regularly work on the same feature over the course of a 3 week sprint. It isn't quite pair programming, but in our current workflow devs regularly push up incomplete code for a colleague to complete. This worked fine before we introduced Gerrit, but now our commits need to represent chunks of test-passing, complete, logical functionality, and so the model breaks. My only idea is to have everybody push up to a separate, untracked branch up until the functionality is ready for review, then squash everything into commits that make sense and push up. Is there another Gerrit-ized workflow that could work? I know this is a widely discussed topic on Google Groups, and that there has recently been some discussion of Gerrit topic reviews, but I wanted to see if there is anybody out there using Gerrit in this way, and what the suggested workflow would be.

• Sharepoint 2007 reset permission inheritance

  - by e-mre

  I have this SharePoint 2007 document library which has several levels of folders and files. Some folders in the middle of the hierarchy do not inherit permissions from their parents and have their unique permissions defined. It is a huge library and there are many folders like this. I am currently changing the permission model of my library and I want to reset all those unique permissions and have all of them inherit permissions from the library root. (Something like "Replace child object permissions" checkbox available in windows files system security window) If this is not possible, seeing a list of folders that have their unique permissions defined would also do.

• Single CAS web application in a cluster

  - by Dolf Dijkstra

  Recently a customer wanted to set up a cluster of CAS nodes to be used together with WebCenter Sites. In the process of setting this up they realized that they needed to create a web application per managed server. They did not want to have this management burden but would like to have one web application deployed to multiple nodes. The reason that there is a need for a unique application per node is that the web-application contains information that needs to be unique per node, the postfix for the ticket id.  My customer would like to externalize the node specific configuration to either a specific classpath per managed server or to system properties set at startup.It turns out that the postfix for ticket ids is managed through a property host.name and that this property can be externalized.The host.name property is used in: /webapps/cas/WEB-INF/spring-configuration/uniqueIdGenerators.xmlIt is set in /webapps/cas/WEB-INF/spring-configuration/propertyFileConfigurer.xmlin a PropertyPlaceholderConfigurer.The documentation for PropertyPlaceholderConfigurer:http://static.springsource.org/spring/docs/2.0.x/api/org/springframework/beans/factory/config/PropertyPlaceholderConfigurer.htmlThis indicates that the properties defined through the PropertyPlaceHolderConfigurer can be externalized.To enable this externalization you would need to change host.properties so it is generic for all the managed servers and thus can be reused for all the managed servers: host.name=${cluster.node.id}Next step is to change the startup scripts for the managed servers and add a system property for -Dcluster.node.id=<something unique and stable>.Viola, the postfix is externalized and the web application can be shared amongst the cluster nodes.

• Development methodology for single web developer?

  - by CaseTA

  I'm a web developer who mostly works with the LAMP stack when it comes to my own projects. Most of the time I just start coding on a project and fixing bugs and adding features as I go along. Often I'll try to use an existing solution such as Wordpress or Drupal. Now that I'm thinking of creating my own web application with businesses as the target group, I feel there's a need for proper analysis and design. Something lightweight for a one person project and still solid enough to handle requirements, user interfaces, security, etc. If you could recommend methodologies and literature I would be grateful.

• Tracking a single page on another domain in Google Analytics

  - by Ross

  I have access to edit a 'mini-site' hosted on our organisation's parent site. I'd like to track this page using Google Analytics, however I don't have access to the front page so I can't verify this as my domain. Using the tracking code for our main site works, however I don't want this data to be confused with similarly named pages on our site (for example, our mini-site is at /radio, and if we had a /radio at our main site this would be counted as the same). Has anyone been in this situation before? I'd like to just redirect visitors to our mini-site to our main site, seeing as it ranks higher in Google, but I've been told to maintain a separate site with our main features.
