  • Why not to use Array of errors instead of Exception Handling !?

    - by Naughty.Coder
    Why not using array of errors instead of throwing errors and check if it's not empty later in the code.... Exception handling is very confusing to me , I can not understand it's purpose ... can anybody enlighten me !? they compare it with die() as better not to stop the execution of the code , why would I stop the execution of code if I don't want to !? ofcourse I do I'm a beginner programmer , it might be confusing to you as well , or because i'm not very experienced in this ugly thing. Please in the context of PHP only.

  • MSDN Example of handling an exception from the TPL - Is this a race condition?

    - by David
    I'm looking at the TPL exception handling example from MSDN @ http://msdn.microsoft.com/en-us/library/dd537614(v=VS.100).aspx The basic form of the code is: Task task1 = Task.Factory.StartNew(() => { throw new IndexOutOfRangeException(); }); try { task1.Wait(); } catch (AggregateException ae) { throw ae.Flatten(); } My question is: Is this a race condition? What happens if task1 throws before the try has executed? Am I missing something that stops this being a race? Shouldn't it be written like this instead: try { Task task1 = Task.Factory.StartNew(() => { throw new IndexOutOfRangeException(); }); task1.Wait(); } catch (AggregateException ae) { throw ae.Flatten(); }

  • Has glassfish 2.1.1 a bug handling http request and handle them twice?

    - by marabol
    I'm using glassfish 2.1.1. I've watched a mysterious http/webservice-call handling. It seams an http request is handled by two different threads. After http basic authentication the first thread is faster. Persisting some data end, but writing response fails in glassfish internal. The second thread fails, because it tries to persist identical data and there are (unique) constrain failures. The response (the failure) of second thread was delivered to client. I don't won't discuss the behavior with the unique constrain failure. I've improve the webservice, so it can handle this better, because it could be happen anytime, that the client send the ws call a second time. But I think, glassfish 2.1.1 has an bug handling http request. Is there any known issue? Have I done an mistake?

  • TabWidget Activity Handling - Does it Create a New Activity EVERY Time?

    - by stormin986
    When a TabWidget is using intents to designate the target Activity for each tab, is there any special handling of those Activities on the Activity Stack outside of the default operation? For Instance, if my app has tabs A, B, and C, and I click them in this order––A, B, A, C, A, B––how will the Activity stack change? My understanding of the default operation, if startActivity() is called each time on the intent, would have the Stack keep loading up new instances of the activities: A, AB, ABA, ABAC, ABACA, ABACAB It's hard to believe that's how it works though... Seems like it would be a waste of resources and could be endless. Can anyone tell me how this will actually work?

  • I'm having a hard time wrapping my head around handling the Activity Lifecycle...

    - by kefs
    So it seems i've created a fatal flaw and coded an app before understanding/handling rotation/lifecycle events.. Currently, all of my code is in onCreate of each activity. I've read a lot of lifecycle tutorials online, including the official dev guide info, but i'm still having an almost unbelievably hard time trying to wrap my head around the rotation/lifecycle events/methods and when to use them correctly. For example, my app currently has an activity that opens the db, inserts a record, then closes the db.. if i rotate my screen on this activity, the data is re-entered into the db. Using the available lifecycle events (onPause(), onResume(), etc..), how would I prevent this db call from happening again? Would I have to pass a variable through the state saying that the db call has been done, and not to do it again? Thanks in advance..

  • IE or Firefox,which one has a more logical CSS handling ?

    - by Najm
    hello there , i know that there is some rules and standards in css handling but i mean which one is closer to a human thinking. for example : when i give a DIV tag a height property of 100px i just want it to be 100px! but in Firefox i should work on min-height or max-width and so on ! there is many like this examlpe , i think IE read css more humanestic against Firefox. i have several experiences in this case , your final nice design in IE can be a mess in Firefox thats because of the way they handle css. Firefox act as a robot but IE act as a human-half robot ! its just my idea. i will be glad to hear and learn from you proffesionals and other friends here. thank you.

  • Java how does Key Event Handling Mechanism(KeyListeners notified) work ?

    - by Carbonizer
    How does application/JVM know which classes if implemented key handling interfaces ? Does it use java Reflections or does it check all the classes for methods ? How can a application or executing JVM understanding to deliver the user event or call the specific methods on a class that implemented the keylistener interface. Does it look at all the classes if those methods are implemented or how does it know which classes implmented keylistener interface ? If you dont implement the keylistener Interface for a class but still implmentation all its methods. Do the class still process the user event occurred ?

  • Away3D & Directional Light w/ Rotating Meshes

    - by seethru
    This is likely a stupid error but I can't seem to find what I've done wrong. I've got a simple scene with 10 cylinders rotating at a default speed. If I grab one of these cylinders I can rotate it in the opposite direction or at a greater speed. I have a single directional light in the scene. It would appear that the directional light is only calculated at initialization and not on further frames. The shadow created by the light rotates with the cylinder giving the impression that the light is rotating when it isn't. Camera & Light Initialization _view = new View3D(); addChild(_view); _view.antiAlias = 4; _view.backgroundColor = 0xFFFFFF; _view.camera.z = -850; _view.camera.y = 0; _view.camera.x = 0; _view.camera.lookAt(new Vector3D()); _view.camera.lens = new PerspectiveLens(15); _view.mousePicker = PickingType.RAYCAST_BEST_HIT; _light = new DirectionalLight(); _light.z = -850; _light.direction = new Vector3D(1, 1, 1); _light.color = 0xFFFFFF; _light.ambient = 0.1; _light.diffuse = 0.7; _view.scene.addChild(_light); Mesh and Material creation var material:TextureMaterial = new TextureMaterial(createPow2Texture(sprite, _colors[i]) , true, false, true); material.animateUVs = true; material.lightPicker = _lightPicker; cylinder = new Mesh(new CylinderGeometry(radius, radius, 13, 70, 1, true, true), material); cylinder.subMeshes[0].scaleU = spriteWidth / sprite.width; cylinder.y = y; cylinder.mouseEnabled = true; cylinder.pickingCollider = PickingColliderType.AS3_BEST_HIT; cylinder.addEventListener(MouseEvent3D.MOUSE_OVER, onMouseOverMesh); cylinder.addEventListener(MouseEvent3D.MOUSE_MOVE, onMouseOverMesh); cylinder.addEventListener(MouseEvent3D.MOUSE_OUT, onMouseOutMesh); _cylinders.push(cylinder); Frame private function onEnterFrame(event:Event):void { for each (var mesh:Mesh in _cylinders) { if (mesh == _mouseOverMesh) continue; mesh.rotationY += 0.25; } _view.render(); }

  • Django - how to write users and profiles handling in best way?

    - by SpankMe
    Hey, I am writing simple site that requires users and profiles to be handled. The first initial thought is to use django's build in user handling, but then the user model is too narrow and does not contain fields that I need. The documentation mentions user profiles, but user profiles section has been removed from djangobook covering django 1.0 (ideally, the solution should work with django 1.2), and the Internet is full of different solutions, not making the choice easier (like user model inheritance, user profiles and django signals, and so on). I would like to know, how to write this in good, modern, fast and secure way. Should I try to extend django builtin user model, or maybe should I create my own user model wide enough to keep all the information I need? Below you may find some specifications and expectations from the working solution: users should be able to register and authenticate every user should have profile (or model with all required fields) users dont need django builtin admin panel, but they need to edit their profiles/models via simple web form Please, let me know how do you solve those issues in your applications, and what is the best current way to handle users with django. Any links to articles/blogs or code examples are highly appreciated!

  • How can I build a generic dataset-handling Perl library?

    - by Pep.
    Hello, I want to build a generic Perl module for handling and analysing biomedical character separated datasets and which can, most certain, be used on any kind of datasets that contain a mixture of categorical (A,B,C,..) and continuous (1.2,3,881..) and identifier (XXX1,XXX2...). The plan is to have people initialize the module and then use some arguments to point to the data file(s), the place were the analysis reports should be placed and the structure of the data. By structure of data I mean which variable is in which place and its name/type. And this is where I need some enlightenment. I am baffled how to do this in a clean way. Obviously, having people create a simple schema file, be it XML or some other format would be the cleanest but maybe not all people enjoy doing something like this. The solutions I can think of are: Create a configuration file in XML or similar and with a prespecified format. Pass the information during initialization of the module. Use the first row of the data as headers and try to guess types (ouch) Surely there must be a "canonical" way of doing this that is also usable and efficient. Thanks p.

  • Adding cancel ability and exception handling to async code.

    - by Rob
    I have this sample code for async operations (copied from the interwebs) public class LongRunningTask { public LongRunningTask() { //do nowt } public int FetchInt() { Thread.Sleep(2000); return 5; } } public delegate TOutput SomeMethod<TOutput>(); public class GoodPerformance { public void BeginFetchInt() { LongRunningTask lr = new LongRunningTask(); SomeMethod<int> method = new SomeMethod<int>(lr.FetchInt); // method is state object used to transfer result //of long running operation method.BeginInvoke(EndFetchInt, method); } public void EndFetchInt(IAsyncResult result) { SomeMethod<int> method = result.AsyncState as SomeMethod<int>; Value = method.EndInvoke(result); } public int Value { get; set; } } Other async approaches I tried required the aysnc page attribute, they also seemed to cancel if other page elements where actioned on (a button clicked), this approach just seemed to work. I’d like to add a cancel ability and exception handling for the longRunningTask class, but don’t erm, really know how.

  • rhel/centos vs. ubuntu (possibly other debian-based systems) linux in handling duplicate ips in the same subnet

    - by johnshen64
    This has bothered me for quite a while but I never found out why or how to change the behavior. ip duplicates could be caused by typos or dhcp errors etc., but they do occur from time to time. in rpm-based systems such as centos, the old server with the duplicate ip wins, and the new server will get an error in bringing up the nic (ip address already used). this is somewhat harmless because we can just fix the system that is coming up. ubuntu only the other hand happily grabs the used ip for itself and leave the old server/device without a valid ip. this is the more dangerous behavior because it causes outages. what i want is to change the ubuntu behavior to that of the centos/rhel so would appreciate any help.

  • How to install MariaDB rpms in CentOS 6.4 using rpm (not yum cmd) + handling mysql-libs conflicts

    - by Pat C
    I need to script the install of MariaDB using the rpm command in CentOS 6.4. I can't use yum since it's going to be an offline install so there's no access to the repository. The only MySQL package installed is mysql-libs as various other packages in CentOS depend on it. When I did a test install of MariaDB with yum it correctly accounted for mysql-libs and uninstalled it at the end as MariaDB could handle the dependencies after it was installed: [root@new-host-6 ~]# yum install MariaDB-client MariaDB-common MariaDB-compat MariaDB-devel MariaDB-server MariaDB-shared Loaded plugins: downloadonly, fastestmirror, refresh-packagekit, security, verify Loading mirror speeds from cached hostfile * base: mirrors.kernel.org * extras: mirror.keystealth.org * updates: mirror.umd.edu Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package MariaDB-client.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-common.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-compat.x86_64 0:5.5.32-1 will be obsoleting ---> Package MariaDB-devel.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-server.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-shared.x86_64 0:5.5.32-1 will be obsoleting ---> Package mysql-libs.x86_64 0:5.1.66-2.el6_3 will be obsoleted --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================================================================================== Package Arch Version Repository Size ==================================================================================================================================================================== Installing: MariaDB-client x86_64 5.5.32-1 mariadb 10 M MariaDB-common x86_64 5.5.32-1 mariadb 23 k MariaDB-compat x86_64 5.5.32-1 mariadb 2.7 M replacing mysql-libs.x86_64 5.1.66-2.el6_3 MariaDB-devel x86_64 5.5.32-1 mariadb 5.6 M MariaDB-server x86_64 5.5.32-1 mariadb 34 M MariaDB-shared x86_64 5.5.32-1 mariadb 1.1 M replacing mysql-libs.x86_64 5.1.66-2.el6_3 Transaction Summary ==================================================================================================================================================================== Install 6 Package(s) Total download size: 53 M Is this ok [y/N]: y Downloading Packages: (1/6): MariaDB-5.5.32-centos6-x86_64-client.rpm | 10 MB 00:06 (2/6): MariaDB-5.5.32-centos6-x86_64-common.rpm | 23 kB 00:00 (3/6): MariaDB-5.5.32-centos6-x86_64-compat.rpm | 2.7 MB 00:02 (4/6): MariaDB-5.5.32-centos6-x86_64-devel.rpm | 5.6 MB 00:06 (5/6): MariaDB-5.5.32-centos6-x86_64-server.rpm | 34 MB 00:23 (6/6): MariaDB-5.5.32-centos6-x86_64-shared.rpm | 1.1 MB 00:00 -------------------------------------------------------------------------------------------------------------------------------------------------------------------- Total 1.3 MB/s | 53 MB 00:40 warning: rpmts_HdrFromFdno: Header V4 DSA/SHA1 Signature, key ID 1bb943db: NOKEY Retrieving key from https://yum.mariadb.org/RPM-GPG-KEY-MariaDB Importing GPG key 0x1BB943DB: Userid: "Daniel Bartholomew (Monty Program signing key) <[email protected]>" From : https://yum.mariadb.org/RPM-GPG-KEY-MariaDB Is this ok [y/N]: y Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Warning: RPMDB altered outside of yum.

My question is, what is the equivalent way to install the MariaDB packages using the rpm command only as opposed to yum? If I do rpm -ivh MariaDB*.rpm, I will get a ton of messages like the following about conflicts with mysql-libs: file /etc/my.cnf from install of MariaDB-common-5.5.32-1.x86_64 conflicts with file from package mysql-libs-5.1.66-2.el6_3.x86_64 file /usr/share/mysql/charsets/Index.xml from install of MariaDB-common-5.5.32-1.x86_64 conflicts with file from package mysql-libs-5.1.66-2.el6_3.x86_64 I then used the --force option to install the MariaDB rpms and uninstalled mysql-lib, I didn't get any weird messages but I'm not sure that is the cleanest method to handle the conflicts and do the install. So can someone confirm that installing MariaDB with the following rpm commands would be the same as using yum to install the packages and handle mysql-libs conflicts/removal: rpm -ivh --force MariaDB*.rpm rpm -e mysql-libs Thanks for any input!

  • How do I stop postfix from handling my mail?

    - by Tatu Ulmanen
    Here's the situation: I have a domain, let's say domain.com. That domain has Google Apps for Business enabled, so all mail delivered to @domain.com will end up at Google (MX records point to Google). I have a PHP script at domain.com that I use to send mail to myself. But when the PHP script tries to send mail to [email protected], Postfix at that server decides that the recipient is a local user (because the address matches the domain Postfix itself is at), and tries to deliver the mail locally. But inevitably fails as the mailbox cannot be found. How can I instruct Postfix to not try to handle locally any emails to @domain.com and just send them forward so Google can pick them up? I have already removed $myhostname from mydestination field in Postfix's main.cf file, and I have restarted Postfix but Postfix still tries to deliver the mail locally. Here's a snip from mail.log that show the problem (addresses replaced): postfix/pickup[20643]: AF718422E5: uid=33 from=<server> postfix/cleanup[20669]: AF718422E5: message-id=<62e706bcca5a0de0bfec6baa576d88a5@server> postfix/qmgr[20642]: AF718422E5: from=<server>, size=517, nrcpt=1 (queue active) postfix/pipe[20678]: AF718422E5: to=<[email protected]>, relay=dovecot, delay=0.62, delays=0.47/0.03/0/0.13, dsn=5.1.1, status=bounced (user unknown) postfix/bounce[20680]: AF718422E5: sender non-delivery notification: 29598422E7 postfix/qmgr[20642]: AF718422E5: removed

  • Handling emails on a web server - Making sure the FQDN is set correctly based on the website sending the email

    - by webnoob
    I have a Windows 2008 Web Edition server hosting multiple websites using IIS 7.5. At the moment, all the emails are sent via the IIS6 SMTP service. The FQDN of the SMTP service is set to the computer name at the moment which isn't correct as it doesn't resolve to a valid DNS entry and is not RFC compliant. Some questions: Is there any way I can change the FQDN of the SMTP service based on the site sending the email? Would it be Ok to just setup mailserver.mydomain.com and use that as the FQDN for all the sites on multiple domains. Should I be using some other mail server software to handle this better? The reason I am asking is lots of emails are hitting spam folders because the settings are incorrect. I have access to the code that is running the websites so if something needs to be done there then that shouldn't be a problem. The sites are written using ASP.NET 2.0. EDIT: I have just found an option to create an SMTP virtual service. Would this be the way forward? Create a virtual server for each site? Thanks.

  • How are large companies handling the storing and cataloging of software installation disks?

    - by CT
    I just started working in the IT department of a small-medium sized construction company with about 200 users. One of my responsibilities is to setup and configure all new machines that come in. I would like suggestions on how to best manage the installation disks and licenses of the software that comes with them. Plus any additional licensed software such as Autocad, Photoshop, etc as well as peripheral driver disks such as printers and scanners. Right now every machine is associated and labeled with an asset id. All asset ids are kept in a spreadsheet with applicable serial numbers, current user, warranty info, and software licenses. The physical disks are then kept within a folder in a cabinet. Each folder is marked with the asset id number as well as the current user. My problems with this is that the system was not maintained very completely before I came to the company. There are plenty of software folders with no asset ids labeled on them. Plenty of missing software folders (most likely are a lot of the unlabeled folders). Folders with names but not asset ids. Machines get switched to different users without the folders and spreadsheet being updated. I am not saying this method would necessarily be bad if it was better implemented and managed, but if I am going to have to take a lot of time to fix this system currently in place. I thought I would ask the community first on how others manage this process in case there are easier, more efficient ways of doing so. Thank you.

  • How do I automate the handling of a problem (no network device found) in Ubuntu 10.04 w/ preseed?

    - by user61183
    I have a preseed file that is doing some automation for an installation of Ubuntu 10.04. At the point where the network hardware is auto-detected, however, it fails to find hardware and displays a message, "No network interfaces detected". To make a long story short, I don't care if it can detect my network interface. How do I do one of the following: Skip that step alltogether. Handle the error page automagically. PS. I found somewhere where it suggested this: netcfg/no_interfaces seen true That didn't work. Thanks

  • In terms of load handling, which is better: one server or two of equivalent power?

    - by seldary
    My goal is to figure out if i'm better off with one strong server, or multiple weaker servers with a load balancer. Does the fact of splitting the load between servers have an effect on the total load my website could take? It's hard to single that out, because there are of course a lot of parameters that affect the results, so some assumptions: Putting failover considerations aside - I know it matters, but for the sake of the question's simplicity, lets assume nothing fails. The servers in the multiple servers option have an accumulated "power" equivalent to the one server option (about the same amount of cores and RAM space). If that is too theoretical, here is a concrete question that could help: Suppose I have several instances of exactly the same server - lets call it S. Suppose that server S can serve a load of up to X calls per time unit. Will two S servers with a load balancer serve 2X calls per time unit? significantly more? significantly less?

  • SQL SERVER – Technical Reference Guides for Designing Mission-Critical Solutions – A Must Read

    - by pinaldave
    Yesterday I was reading architecture reference material helping my friend who was looking for material in this respect. While working together we were searching twitter, facebook and search engines to find relevant material.While searching online we end up on very interactive reference point. Once I send the same to him, he replied he may not need anything more after referencing this material. The best part of this article was it gives access to various aspect of the technology of the image map. Here is the abstract of the original article from the site: The Technical Reference Guides for Designing Mission-Critical Solutions provide planning and architecture guidance for various mission-critical workloads deployed by users. These guides reflect the knowledge gained by Microsoft while working with customers on mission-critical deployments. Each guide provides not only the key technical concepts and information helpful for design, but also “lessons learned,” best practices, and references to customer case studies. Once you click on any of the desired topic, you will see further detailed image map of the selected topic. Personally once I ended up on this site, I was there for more than 2 hours clicking through various links.

  • Rendering different materials in a voxel terrain

    - by MaelmDev
    Each voxel datapoint in my terrain model is made up of two properties: density and material type. Each is stored as an unsigned integer value (but the density is interpreted as a decimal value between 0 and 1). My current idea for rendering these different materials on the terrain mesh is to store eleven extra attributes in each vertex: six material values corresponding to the materials of the voxels that the vertices lie between, three decimal values that correspond to the interpolation each vertex has between each voxel, and two decimal values that are used to determine where the fragment lies on the triangle. The material and interpolation attributes are the exact same for each vertex in the triangle. The fragment shader samples each texture that corresponds to each material and then uses the aforementioned couple of decimal values to interpolate between these samples and obtain the final textured color of the fragment. It should work fine, but it seems like a big memory hog. I won't be able to reuse vertices in the mesh with indexing, and each vertex will have a lot of data associated with it. It also seems pretty slow. What are some ways to improve or replace this technique for drawing materials on a voxel terrain mesh?
