  • SATA drive not recognized when installing RHEL 5.1 on PowerEdge R410

    - by Rachel
    Here's my setup: Dell R410 with Perc S100 (software) raid controller on an Intel ICH10R chipset The first problem is that the Perc S100 is only supported on windows. I'm trying to install RHEL 5.1. It boots from the cdrom, but later the installer can't see the cdrom or hard drive. Both are connected to the on-board sata controller. The only options in the R410 bios for SATA are ATA or RAID. I don't need raid, I just want a single drive setup.

  • Baseline for GIS Applications

    - by Geertjan
    The application I introduced here yesterday can best be understood via its author's explanation: "As I developed several different WorldWind-based applications, I noticed that they all started out the same. Terramenta was born so I wouldn't have to recreate the baseline every time, I could just provide NetBeans plugin modules to introduce the new features required by different projects." So, to try it out for myself, I checked out the sources from the Mercurial repo today, built them, and ran them. hg clone https://bitbucket.org/heidtmare/terramenta On Windows, things worked fine, on Ubuntu they didn't because the relevant native libraries aren't provided yet out of the box. Here's the result: The above provides the WorldWind globe, together with all the standard options, e.g., for showing names and other WorldWind features, together with several features that I don't understand yet, such as tools for creating shapes and a recorder for replaying sequences. The complete application is like this, i.e., one single functionality module is provided, which exposes several API packages that can be extended: It would really be cool if the above module could also be added to a Maven-based application via a reference to a Maven repository, in the way that Timon Veenstra and the AgroSense team have made available their GeoViewer. One cool thing from the GeoViewer solution is the Flamingo menubar, which I added to Terramenta by simply putting the dependency below into the application POM: <dependency>    <groupId>nl.cloudfarming.client</groupId>    <artifactId>menu</artifactId>    <version>1.0.24</version></dependency> The result, without doing anything other than the above: I am looking forward to helping to document the use cases and developer scenarios for Terramenta! Something like this, created by Timon to demonstrate the GeoViewer use case would be cool to have: http://java.net/projects/agrosense/pages/ExampleGeoviewerNormal

  • 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.

  • Webserver insists on opening "blog1.php" instead of "index.php"

    - by pepoluan
    I'm at my wits' end. I have just ripped out a website and in the process of rebuilding everything. Previously, the 'home page' of the website is a blog, with the address "www.mydomain.com/blog1.php". After exporting everything, I deleted the whole directory, and -- based on request -- immediately create a blog/ directory. The idea is to get the blog back up as soon as possible, and temporarily redirect people accessing www.mydomain.com to the blog. Accessing the blog via http://www.mydomain.com/blog/ works. So I put in an index.php file containing a (temporary) redirect to the blog's address. The problem: The server insists on opening blog1.php instead of index.php. Even after we deleted all the files (including .htaccess). And even putting in a new .htaccess file with the single line of DirectoryIndex index.php doesn't work. The server stubbornly wants blog1.php. Now, the server is actually a webhosting, so I have no actual access to it. I have to do my work via cPanel. Currently, I work around this issue by creating blog1.php; but I really want to know why the server does not revert to opening index.php. Did I perhaps miss some important settings in the byzantine cPanel menu page?

  • Configuring BitLocker on existing Windows Server 2008

    - by neildeadman
    On our file server, we want to enable BitLocker so that we can encrypt a single drive and I know that we have to also encrypt the drive the system is installed on. In my tests with VMs, I have to create a partition on the same disk as Windows is installed either before I install Windows or after (I can use the BitLocker Drive Preparation Tool). This tool shrinks the C: drive to make way for a 1.5GB partition. I'm a little concerned about doing this with a live system so wanted to see if it was possible to get BitLocker to use a partition on another drive?

  • Website: Requested filename being rewritten

    - by horatio
    I have been unable to find an answer via search. I have a website (I do not administer the servers) where the server will serve a different file than the one requested. I first noticed this when using a filename of the following form: _foo.php (single underscore) If I request foo.php (does not exist), the server returns _foo.php. By "returns" I mean that the server decides I meant _foo.php, processes the php file, and serves the output. If I request afoo.php, zfoo.php, or even __foo.php (two underscores) (these files do not exist) the server returns _foo.php. If I request aafoo.php, the server returns 404. To sum up: the server seems to be doing a partial filename match. My question is: what is happening and is this accepted behavior for a web server (or standard behavior of a common mod/package/etc)?

  • BizTalk 2009 - Scoped Record Counting in Maps

    - by StuartBrierley
    Within BizTalk there is a functoid called Record Count that will return the number of instances of a repeated record or repeated element that occur in a message instance. The input to this functoid is the record or element to be counted. As an example take the following Source schema, where the Source message has a repeated record called Box and each Box has a repeated element called Item: An instance of this Source schema may look as follows; 2 box records - one with 2 items and one with only 1 item. Our destination schema has a number of elements and a repeated box record.  The top level elements contain totals for the number of boxes and the overall number of items.  Each box record contains a single element representing the number of items in that box. Using the Record Count functoid it is easy to map the top level elements, producing the expected totals of 2 boxes and 3 items: We now need to map the total number of items per box, but how will we do this?  We have already seen that the record count functoid returns the total number of instances for the entire message, and unfortunately it does not allow you to specify a scoping parameter.  In order to acheive Scoped Record Counting we will need to make use of a combination of functoids. As you can see above, by linking to a Logical Existence functoid from the record/element to be counted we can then feed the output into a Value Mapping functoid.  Set the other Value Mapping parameter to "1" and link the output to a Cumulative Sum functoid. Set the other Cumulative Sum functoid parameter to "1" to limit the scope of the Cumulative Sum. This gives us the expected results of Items per Box of 2 and 1 respectively. I ran into this issue with a larger schema on a more complex map, but the eventual solution is still the same.  Hopefully this simplified example will act as a good reminder to me and save someone out there a few minutes of brain scratching.

  • Saving Dragged Dropped items position on postback in asp.net [closed]

    - by Deeptechtons
    Ok i saw many post's on how to serialize the value of dragged items to get hash and they tell how to save them. Now the question is how do i persist the dragged items the next time when user log's in using the has value that i got eg: <ul class="list"> <li id="id_1"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_2"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_3"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_4"> <div class="item ui-corner-all ui-widget"> </div> </li> </ul> which on serialize will give "id[]=1&id[]=2&id[]=3&id[]=4" Now think that i saved it to Sql server database in a single field called SortOrder. Now how do i get the items to these order again ? the code to make these sort is below,without which people didn't know which library i had used to sort and serialize <script type="text/javascript"> $(document).ready(function() { $(".list li").css("cursor", "move"); $(".list").sortable(); }); </script>

  • Exim redirect all unexisting accounts for local domains to a specific account

    - by tntu
    I want to route all incoming emails for local domains only to a single account if an account is not setup for that user. I would also like each email to be written in it's own file in user folder. I have a catchall user with /home/catchall/ path where I have a mail folder made for this but so far emails wither fail to deliver (thus my rule did not work) or they do deliver to /etc/mail/catchall file. I have been trying to put something together from the Exim configuration but so far nothing seem to work. http://exim.org/exim-html-current/doc/html/spec_html/ch20.html

  • How do you structure your shared code so that it is "re-findable" for new developers?

    - by awmckinley
    I started working at my current job about 8 months ago, and its been one of the best experiences I've had as a young programmer. It's a small company, and both my co-developers are brilliant guys. One of the practices that they both have been encouraging is lots of code-reuse. Our code base is mainly C#, and we're using a centralized revision control system. The way the repository is currently structured, there is a single folder in which all shared class libraries are placed (along with unit tests for each library), and our revision control system allows for sharing or linking those libraries out to other projects. What I'm trying to understand at this point is how the current structure of the folder can be made more conducive for finding those libraries again. I've talked to the other developers about this, and they agree that it's gotten a little messy. I find that I am sometimes "reinventing the wheel" because I didn't realize that there was an existing piece of code that solved a particular problem. The issue is complicated further by the fact that we're sharing some code between ASP.NET MVC2, WinForms, and Windows CE projects, and sharing code between applications built against multiple versions of .NET. How do other people approach this? Is the answer in naming the libraries in a certain way or is it preferable to invest in some code-search software? Is the answer in doc comments? Should we be sharing libraries at all or should we simply branch the class libraries for re-use? Thanks for any and all help!

  • Unset the system immutable bit in Mac OS X

    - by skylarking
    In theory I believe you can unlock and remove the system immutable bit with: chflags noschg /Path/To/File But how can you do this when you've set the bit as root? I have a file that is locked, and even running this command as root will not work as the operation is not permitted. I tried logging in as Single-User mode to no avail. I seem to remember that even though you are in as root you are in at level '1'. And to be able to remove the system-immutable flag you need to be logged in at level '0'. Does this have something to do with this issue?

  • What is logical cohesion, and why is it bad or undesirable?

    - by Matt Fenwick
    From the c2wiki page on coupling & cohesion: Cohesion (interdependency within module) strength/level names : (from worse to better, high cohesion is good) Coincidental Cohesion : (Worst) Module elements are unrelated Logical Cohesion : Elements perform similar activities as selected from outside module, i.e. by a flag that selects operation to perform (see also CommandObject). i.e. body of function is one huge if-else/switch on operation flag Temporal Cohesion : operations related only by general time performed (i.e. initialization() or FatalErrorShutdown?()) Procedural Cohesion : Elements involved in different but sequential activities, each on different data (usually could be trivially split into multiple modules along linear sequence boundaries) Communicational Cohesion : unrelated operations except need same data or input Sequential Cohesion : operations on same data in significant order; output from one function is input to next (pipeline) Informational Cohesion: a module performs a number of actions, each with its own entry point, with independent code for each action, all performed on the same data structure. Essentially an implementation of an abstract data type. i.e. define structure of sales_region_table and its operators: init_table(), update_table(), print_table() Functional Cohesion : all elements contribute to a single, well-defined task, i.e. a function that performs exactly one operation get_engine_temperature(), add_sales_tax() (emphasis mine). I don't fully understand the definition of logical cohesion. My questions are: what is logical cohesion? Why does it get such a bad rap (2nd worst kind of cohesion)?

  • Hyper-V shutdown/start up host causing issues in VMs

    - by Colin Desmond
    I have a single physical host, running 2008 R2 with Hyper-V, all fully updated. On that host I am running 3 clients, a DC, a web server and a SQL Server 2008 R2 SP1. All are running on Windows Server 2008 R2, again all fully patched. Generally all is fine, but sometimes and not repeatably, when I shutdown the host properly, which suspends the Clients, when it all comes up again, SQL Server is no longer running and the IIS App Pool I am running the website in needs to be told which account to run in again! Any ideas!?

  • Assigning valid moves on board game

    - by Kunal4536
    I am making a board game in unity 4.3 2d similar to checkers. I have added an empty object to all the points where player can move and added a box collider to each empty object.I attached a click to move script to each player token. Now I want to assign valid moves. e.g. as shown in picture... Players can only move on vertex of each square.Player can only move to adjacent vertex.Thus it can only move from red spot to yellow and cannot move to blue spot.There is another condition which is : if there is the token of another player at the yellow spot then the player cannot move to that spot. Instead it will have to go from red to green spot. How can I find the valid moves of the player by scripting. I have another problem with click to move. When I click all the objects move to that position.But I only want to move a single token. So what can i add to script to select a specific object and then click to move the specific object.Here is my script for click to move. var obj:Transform; private var hitPoint : Vector3; private var move: boolean = false; private var startTime:float; var speed = 1; function Update () { if(Input.GetKeyDown(KeyCode.Mouse0)) { var hit : RaycastHit; // no point storing this really var ray = Camera.main.ScreenPointToRay (Input.mousePosition); if (Physics.Raycast (ray, hit, 10000)) { hitPoint = hit.point; move = true; startTime = Time.time; } } if(move) { obj.position = Vector3.Lerp(obj.position, hitPoint, Time.deltaTime * speed); if(obj.position == hitPoint) { move = false; } } }`

  • Why Standards Place Limits on Data Transfer Rates?

    - by Mehrdad
    This is a rather general question about hardware and standards in general: Why do they place limits on data transfer rates, and disallow manufacturers from exceeding those rates? (E.g. 100 Mbit/s for Wireless G, 150 Mbit/s for Wireless N, ...) Why not allow for some sort of handshake protocol, whereby the devices being connected agree upon the maximum throughput that they each support, and use that value instead? Why does there have to be a hard-coded limit, which would require a new standard for every single improvement to a data rate?

  • Cursor seems to freeze in the first attempt of typing - Unity 3D, 12.04

    - by Denis
    It happens in the first attempt of typing, no matter is after the startup, or 5 minutes later, or then after. The cursor (or maybe it's the system) seems to freeze, no matter the application I use, taking up 5 sec to appear what is typed. Subsequently, everything is normal, using another applications. @Anwar Shah suggested it could be a daemon waiting to run before the lauching of the first application. Turning off Zeitgest didn't help. It occurs only with Unity-3d. Tested with Unity-2d, everything is fine. Tried to change some Compiz settings, nothing worked, although not tested with every single parameter. Also I deactivated Ati proprietary driver, no effect. My system: AMD E350 1.6Gh, 2G-Ram, ATI graphics - Ubuntu 12.04, 64bits. Update 1: the cursor is blinking normally before I start typing. After the first character (which is not showed), seems to freeze, taking 5 seconds to get normal again. Very annoying, specially when you want to access login sites. Update 2: I tested on a different and old machine (Athlon 64 4800 x2, 4Gb ram, no problems - takes 2 seconds, acceptable. I think it could be related to my specific hardware (Samsung RV415), but not sure about it. Anyone experiencing something similar? Is that what I should expect, or can be fixed or improved? Thanks.

  • Why does Windows share permissions change file permissions?

    - by Andrew Rump
    When you create a (file system) share (on windows 2008R2) with access for specific users does it changes the access rights to the files to match the access rights to the share? We just killed our intranet web site when sharing the INetPub folder (to a few specified users). It removed the file access rights for authenticated users, i.e., the user could not log in using single signon (using IE & AD)! Could someone please tell me why it behaves like this? We now have to reapply the access right every time we change the users in the share killing the site in the process every time!

  • Is creating a separate pool for each individual image created from a png appropriate?

    - by Panzercrisis
    I'm still possibly a little green about object-pooling, and I want to make sure something like this is a sound design pattern before really embarking upon it. Take the following code (which uses the Starling framework in ActionScript 3): [Embed(source = "/../assets/images/game/misc/red_door.png")] private const RED_DOOR:Class; private const RED_DOOR_TEXTURE:Texture = Texture.fromBitmap(new RED_DOOR()); private const m_vRedDoorPool:Vector.<Image> = new Vector.<Image>(50, true); . . . public function produceRedDoor():Image { // get a Red Door image } public function retireRedDoor(pImage:Image):void { // retire a Red Door Image } Except that there are four colors: red, green, blue, and yellow. So now we have a separate pool for each color, a separate produce function for each color, and a separate retire function for each color. Additionally there are several items in the game that follow this 4-color pattern, so for each of them, we have four pools, four produce functions, and four retire functions. There are more colors involved in the images themselves than just their predominant one, so trying to throw all the doors, for instance, in a single pool, and then changing their color properties around isn't going to work. Also the nonexistence of the static keyword is due to its slowness in AS3. Is this the right way to do things?

  • what are some good interview questions for a position that consists of reviewing code for security vulnerabilities?

    - by John Smith
    The position is an entry-level position that consists of reading C++ code and identifying lines of code that are vulnerable to buffer overflows, out-of-bounds reads, uncontrolled format strings, and a bunch of other CWE's. We don't expect the average candidate to be knowledgeable in the area of software security nor do we expect him or her to be an expert computer programmer; we just expect them to be able to read the code and correctly identify vulnerabilities. I guess I could ask them the typical interview questions: reverse a string, print a list of prime numbers, etc, but I'm not sure that their ability to write code under pressure (or lack thereof) tells me anything about their ability to read code. Should I instead focus on testing their knowledge of C++? Ask them if they understand what a pointer is and how bitwise operators work? My only concern about asking that kind of question is that I might unfairly weed out people who don't happen to have the knowledge but have the ability to acquire it. After all, it's not like they will be writing a single line of code, and it's not like we are looking only for people who already know C++, since we are willing to train the right candidate. (It is true that I could ask those questions only to those candidates who claim to know C++, but I'd like to give the same "test" to everyone.) Should I just focus on trying to get an idea of their level of intelligence? In other words, should I get them to talk and pay attention to the way they articulate their thoughts, and so on?

  • Javascript Canvas Drawing Efficiency

    - by jujumbura
    I have just recently started some experiments with game development in Javascript/HTML5, and so far it has been going pretty well. I have a simple test scene running with some basic input handling, and a hundred-ish drawImage() calls with a few transforms. This all runs great on Chrome, but unfortunately, it already chugs on Firefox. I am using a very large canvas ( 1920 x 1080 ), but it doesn't seem like I should be hitting my limit already. So on that note, I was hoping to ask a few questions: 1) What exactly is done on the CPU vs. the GPU in terms of canvas and drawImage()? I'm afraid the answer is probably "it depends on the browser", but can anybody give me some rules of thumb? I naively imagined that each drawImage call results in a textured quad on the GPU with the canvas effectively being a render target, but I'm wondering if I'm pretty far off base there... 2) I have seen posts here and there with people saying not to use the translate(), rotate(), scale() functions when drawing on the canvas. Am I adding a lot of overhead just by adding a translate() call, as opposed to passing in the x,y to drawImage()? Some people suggest using "transate3d", etc., which are CSS properties, but I'm not sure how to use them within a scene. Can they be used for animated sprites within a single canvas? 3) I have also seen a lot of posts with people mentioning that pre-building canvases and then re-using them is a lot faster than issuing all the individual draw calls again. I am guessing that my background should definitely be pre-built into a canvas, but how far should I take this? Should I maintain an individual canvas for each sprite, to cache all static image data when not animating? Thank you much for your advice!

  • Automated Acceptance tests under specific contraints

    - by HH_
    This is a follow up to my previous question, which was a bit general, so I'll be asking for a more precise situation. I want to automate acceptance testing on a web application. Briefly, this application allows the user to create contracts for subscribers with the two constraints: You cannot create more than one contract for a subscriber. Once a contract is created, it cannot be deleted (from the UI) Let's say TestCreate is a test case with tests for the normal creation of a contract. The constraints have introduced complexities to the testing process, mainly dependencies between test cases and test executions. Before we run TestCreate we need to make sure that the application is in a suitable state (the subscriber has no contract) If we run TestCreate twice, the second run will fail since the state of the application will have changed. So we need to revert back to the initial state (i.e. delete the contract), which is impossible to do from the UI. More generally, after each test case we should guarantee that the state is reverted back. And since, in this case, it is impossible to do it from the UI, how do you handle this? Possible solution: I thought about doing a backup of the database in the state that I desire, and after each test case, run a script which deletes the db and restores the backup. However, I find that to be too heavy to do for each single test case. In addition, what if some information are stored in files? or in multiple or unaccessible databases? My question: In this situation, what would an experienced tester do to write automated and maintanable tests. Thank you. More info: I'm trying to integrate tests into a BDD framework, which I find to be a neat solution for test documentation and communication, but it does not solve this particular problem (it even makes it harder)

  • Multiple test Active Directory envirovments hand in hand with production domain controllers

    - by MadBoy
    What's the best approach of having multiple test environments next to production one? We have multiple programming teams that build solutions that use Active Directory very often. We have tried different approaches, starting with their own domain controllers (in same subnet), or additional OU's in our production AD that the team gets control over and can create/delete accounts within that one OU. We thought of possible 4 solutions: Setting up separate OU's in ou production env. Creating subdomains for our contoso.com domain like test.contoso.com, something.contoso.com and delegating control to the teams (would we need additional DC's or the two that we have already would be enough to hold this? Setting up additional test domain controler that has a trust to our main domain and all teams can use the test domain controler as they please. Setting up single domain controller for every team/project. We're taking in consideration amount of resources needed, security (for example having multiple domain controlers with multiple passwords may lead users to use simpler passwords) and overall best practices for this scenario.

  • What technical test should I give to a job candidate

    - by Romain Braun
    I'm not sure if this is the right stackexhange website, but : I have three candidates coming in tomorrow. One has 15 years of experience in PHP, and the two others have about 1 year of experience in PHP/ frontend development. For the last ones I was thinking about a test where they would have to develop a web app allowing users to manage other users, as in : Display a list of users, display a single user, modify an user, and add extended properties to an user. This way it would feature html, css, js, ajax, php and SQL. Do you think this would be a good test? What test should I give to the first one? He needs something much more difficult, I guess. I'm also listening, if you have any advice/ideas about what makes a good developer, and what I should pay attention to in the guys' codes. I was also considering thinking outside of the box, more algorithm-related, and asked him to make the fastest function to tell if a number is a prime number, because there are a lot of optimizations you can apply to such a function. They have one day to do it.
