  • How to add data from an NSTextField to a Core Data Attribute without having to press Return or Tab a

    - by roy-fleming
    I use a sheet with 3 NSTextFields and a Cancel- and OK-Button to edit the attributes of a Core Data Entity. The text entered in the NSTextFields is only updated in the Core Data Entity if i press Tab or Return after writing in the NSTextField or if i focus another NSTextField with the mouse. If i just enter text in an NSTextField and press the OK-Button the entered text is lost. Is there some attribute i can set in Interface Builder to change this NSTextField behaviour?

  • "state is undetermined" when starting Grails app on CloudFoundry

    - by SeattleStephens
    I have a Grails app that has been running on CloudFoundry for months. I updated the app from Grails 2.0.4 to 2.1.0 and also updated a few plugins I have been using. Now when I push the app to CloudFoundry and do the start, I receive the error: 'appname' state is undetermined, not enough information available. The tomcat Catalina log shows the NoClassDefFoundError below. I've read about issues with the Ivy cache but have not looked into that yet. I have updated vmc to the latest version (0.3.18).

  • Evolution of an Application: how to manage and improve core engine?

    - by Phil Carter
    The web application I work on has been live for a year now, but it's time for it to evolve and one of the ways in which it is evolving is into a multi-brand application - in this case several different companies using the application, different templates/content and some slight business logic changes between them. The problem I'm facing is implementing a best practice across the site where there are differences in business logic for each brand. These will mostly be very superficial, using a an alternative mailing list provider or capturing some extra data in a form. I don't want to have if(brand === x) { ... } else { ... } all over the site especially as most of what needs to be changed can be handled with extending the existing class. I've thought of several methods that could be used to instantiate the correct class, but I'm just not sure which is going to be best especially as some seem to lead to duplication of more code than should be necessary. Here's what I've considered: 1) Use a Static Loader similar to Zend_Loader which can take the class being requested, and has knowledge of the Brand and can then return the correct object. $class = App_Loader::getObject('User', $brand); 2) Factory classes. We use these in the application already for Products but we could utilise them here also to provide a transparent interface to the class. 3) Routing the page request to a specific brand controller. This however seems like it would duplicate a lot of code/logic. Is there a pattern or something else I should be considering to solve this problem? 4) How to manage a growing project that has multiple custom instances in production? Update This is a PHP application so the decisions on which class to load are made per request. There could be upwards of 100+ different 'brands' running.

  • SceneManagers as systems in entity system or as a core class used by a system?

    - by Hatoru Hansou
    It seems entity systems are really popular here. Links posted by other users convinced me of the power of such system and I decided to try it. (Well, that and my original code getting messy) In my project, I originally had a SceneManager class that maintained needed logic and structures to organize the scene (QuadTree, 2D game). Before rendering I call selectRect() and pass the x,y of the camera and the width and height of the screen and then obtain a minimized list containing only visible entities ordered from back to front. Now with Systems, originally in my first attempt my Render system required to get added all entities it should handle. This may sound like the correct approach but I realized this was not efficient. Trying to optimize It I reused the SceneManager class internally in the Renderer system, but then I realized I needed methods such as selectRect() in others systems too (AI principally) and make the SceneManager accessible globally again. Currently I converted SceneManager to a system, and ended up with the following interface (only relevant methods): /// Base system interface class System { public: virtual void tick (double delta_time) = 0; // (methods to add and remove entities) }; typedef std::vector<Entity*> EntitiesVector; /// Specialized system interface to allow query the scene class SceneManager: public System { public: virtual EntitiesVector& cull () = 0; /// Sets the entity to be used as the camera and replaces previous ones. virtual void setCamera (Entity* entity) = 0; }; class SceneRenderer // Not a system { vitual void render (EntitiesVector& entities) = 0; }; Also I could not guess how to convert renderers to systems. My game separates logic updates from screen updates, my main class have a tick() method and a render() method that may not be called the same times. In my first attempt renderers were systems but they was saved in a separated manager, updated only in render() and not in tick() like all other systems. I realized that was silly and simply created a SceneRenderer interface and give up about converting them to systems, but that may be for another question. Then... something does not feel right, isn't it? If I understood correctly a system should not depend on another or even count with another system exposing an specific interface. Each system should care only about its entities, or nodes (as optimization, so they have direct references to relevant components without having to constantly call the component() or getComponent() method of the entity).

  • New Workstation &ndash; Lenovo W530 Core i7 32GB 256GB SSD Win8Pro

    - by Brian Lanham
    So I pretty-much have my new machine up and running full-time. I am still going to have to hit my old workstation for some things but am more-or-less working on my new machine.  It’s really fast. And Bret was right, I’m not so far using all the RAM. 16 would have been enough but as @CodeMonkeyJava “go big or go home”. Windows 8 is…interesting.  So far I still seem to do most of my work in the “Desktop”.  However, I like the Store concept and I like the Metro UX.  Live tiles are also nice.  I really like how I can switch between Desktop and Metro easily.  Overall I think Microsoft has done a great job of combining the needed experience for touch and mouse. My overall Windows 8 rating is 5.9 because of the video card. Otherwise I’m hitting 7.8.  The system boots from cold in about 11 seconds and performs complete shutdown in 4.7 seconds.  It wakes from sleep in less than 1 second. VS 2012 starts and restarts almost instantly.  In fact, I find myself staring at the start page without realizing it.  Build time doesn’t seem to be significantly increased but it is faster. I seem to already be reinvigorated for work with this new machine. I’m looking forward to the performance.

  • What design pattern (in python) to use for properly seperate runtime infos with core code?

    - by user1824372
    I am not sure if this is a clear question. I work on a python project that is based on terminal(console), for which I am planning to implement a GUI. I am not major in CS so I really have no idea about how to effectively design a message system such that: in console, it provide nice look info when runtime. in GUI, it is directed to a certain widget, let's say, a text label, or a bottom bar, or a hide-able frame. Do you have any suggestions? Currently, I am using print function to provide essential informations on stdout during runtime. So a lot of print .... are distributed here and there among the code. I am thinking to use macro-like variables such as 'FILE_NOT_EXTIS_MESSAGE' for printing, and define the variables in one file. Is this a standard way that people always do? How about I introduce a logging system? In sum, I am ask for a pattern that people are commonly using for handling of screen output information with high effectiveness and adaptivity.

  • Websphere federated repository for Active Directory

    - by Drakiula
    Hi, What I am trying to achieve is to have Websphere 6.1 use Active Directory users authentication. Websphere is running on Windows 2008 R2. What I've done already: Succesfully setup a federated repository for Windows Active Directory (LDAP); Create a realm definition for the federated repository previously defined; Set the realm definition as the current real definition. Stop the Websphere service. When I attempt to start the Websphere service again, it crashes with the following stacktrace: ------Start of DE processing------ = [9/3/10 2:36:14:133 PDT] , key =

  • Multiple subnets on isc-dhcp-server using ddns with bind9

    - by legioxi
    On my network I have two subnets: 10.100.1.0/24 - Wired/wireless 10.100.7.0/24 - VPN Both subnets are served by isc-dhcp-server running on a Debian VM. This same VM runs bind9 for my DNS. ISC-DHCP-SERVER is configured to use DDNS and update BIND9 with hosts/IPs. Everything runs great until a device drops off the wired/wireless network and pops onto the VPN. When connecting on the VPN, a DHCP lease is handed out on the new subnet but DDNS does not update BIND9. Since the device has A/TXT/PTR records it appears ISC-DHCP-SERVER won't switch them to the new IP. The logs show: Connect to wireless: Nov 6 20:55:13 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': adding an RR at 'demo-iphone.internal.mydomain.com' A Nov 6 20:55:13 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': adding an RR at 'demo-iphone.internal.mydomain.com' TXT Nov 6 20:55:13 core-server dhcpd: DHCPACK on 10.100.1.160 to FF:FF:FF:FF:FF:FF (demo-iphone) via eth0 Nov 6 20:55:13 core-server dhcpd: Added new forward map from demo-iphone.internal.mydomain.com to 10.100.1.160 Nov 6 20:55:13 core-server dhcpd: Added reverse map from 160.49.21.172.in-addr.arpa. to demo-iphone.internal.mydomain.com Switch to VPN: Nov 6 20:56:34 core-server dhcpd: DHCPOFFER on 10.100.7.101 to BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': update unsuccessful: demo-iphone.internal.mydomain.com: 'name not in use' prerequisite not satisfied (YXDOMAIN) Nov 6 20:56:34 core-server dhcpd: DHCPREQUEST for 10.100.7.101 (10.100.1.2) from BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server dhcpd: DHCPACK on 10.100.7.101 to BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': update unsuccessful: demo-iphone.internal.mydomain.com/TXT: 'RRset exists (value dependent)' prerequisite not satisfied (NXRRSET) Nov 6 20:56:34 core-server dhcpd: Forward map from demo-iphone.internal.mydomain.com to 10.100.7.101 FAILED: Has an address record but no DHCID, not mine. One thing to note is that the MAC of the device when connecting via VPN is the MAC of my Cisco ASA5512X and not the actual device. The ASA is relaying the DHCP request from the VPN client to the VM running ISC-DHCP-SERVER. Is there a way to get DDNS working in this scenario?

  • Is a 2006 Mac Mini's processor upgradeable to a Core 2 Duo?

    - by chiurox
    I have a Mac Mini with Core Solo 1.5GHz, 512mb RAM, 60gb HDD, etc... I know, it's very old but since it's lying around here, I wanted to bump it up for general usage and some experimental iPhone development. Also, Snow Leopard can't be installed as it doesn't have enough RAM. I browsed around but I'm not sure if this Mac Mini's motherboard accepts a Core2Duo (at least a 2.0GHz). If anyone could inform me which generation of Core2Duo it still accepts, I'd be grateful.

  • is it dangerous for the processor core to be *always* loaded at 100%?

    - by javapowered
    In my HFT software I plan to use one core for stock index calculation. That would be simply while(true) loop without any delays which will calculate (sum and multiply) components as often as possible (so millions times per second) and I plan to do that 8 hours per day every day. I was never before loading my computer to 100% full time every day regullary. May it be dangerous? Do processor has kind of "resource" (very big of course) after which it can stopped working?

  • Why does F@H not bind to more than one core on Windows?

    - by warren
    I have been contributing to Stanford's Folding@Home project for some time with most of the computers I own. I just installed the Windows client on a new machine running Windows 7, but see that the F@H process only binds to one CPU core. Is this due to it being run on Windows? (I have the 64-bit edition of Windows 7 installed.) On the Mac and under 64-bit Linux distros, it will run across all available CPU cores.

  • Dedicated Hosting offering Intel Core 2 Quad @ 6GHz. Is this real?

    - by Daniel Magliola
    Hi, sorry if this is a very dumb question, but... I just got an offer from a dedicated hosting company, offering me a box with "2 Core 2 Quad processors @ 6GHz" I didn't know we could get 6GHz, and some googling turned out a bunch of people getting that, after overclocking like crazy, which seems to confirm my suspicion. Are there hostings offering 6GHz CPUs, or are these people outright lying to me? Thank you!
