  • Problems using PHP on a Plesk Windows dedicated server

    - by wpsmdouble
    I'm having a few issues with my dedicated Windows server that has a Plesk panel: 1.) I can't send e-mail via PHP's mail() function, it always returns the following error: SMTP server response: 550 Requested action not taken: mailbox unavailable or not local Which setting should I alter in order to enable sending mail? 2.) The exec() and passthru() PHP functions don't work; their outputs are blank even when I try to run simple commands such as dir. Is there an option that I can toggle in the control panel to enable this functionality?

  • Ubuntu One isn't syncing in Windows 7

    - by tuxtu
    Ubuntu One was working just fine in friend's computer on Windows 7. Problem is that, suddenly it has stopped syncing. I want to share some observation regarding this problem. Hope this could be helpful to solve the problem. If I upload any file directly on web (using browser), the amount of file size (KB/GB) changed in both places, Web dashboard and Ubuntu One control panel on Windows 7, but I can't find the file on PC. "File sync in progress" hangs on the U1 control panel on windows for indefinite time. If I keep any file in the U1 synced folder, that's not available on the PC and the total amount of file size isn't changed anywhere. "File sync in progress" dialogue is always there, since the starting of the PC. User using the PC with administrative previlage. Hope this problem will be solved quickly.

  • Re-sizing the form without scaling the GUI

    - by Bmoore
    I am writing a turn based strategy game in C#. My GUI implementation consists of class that extends Form containing a class that extends Panel. When I render the GUI I draw to the paint method in the panel. I am trying to figure out what is the best way for handling form re-size events. I know I want a minimum window size, but I would prefer to not have a maximum or a set size. Ideally the GUI would reveal more/less of the map as the user changes the window size. I would like to avoid scaling the graphics if at all possible. What is the best way to handle re-size events?

  • Triple Monitor Setup with Nvidia and Compiz

    - by AndrewX192
    I have a triple monitor setup with two video cards on Ubuntu 10.04. I have the monitors and graphics cards currently setup as follows: Nvidia Geforce 210 #1 - 1920x1080 Monitor (Twinview) [Center - Monitor #1] - 1920x1080 Monitor (Twinview) [Right - Monitor #2] Nvidia Geforce 210 #2 - 1920x1080 Monitor (Separate X Screen) [Left - Monitor #3] This works fine, except when I open a program, it shows up in between monitor #1 and #2 - meaning I have to drag it to one screen before I can use the window. Gnome2's gnome-panel also does not work on the twinview setup; it spans between both monitors, but it does not redraw (ex: the clock never changes). In addition, when I maximize an application, it spans both monitors, which is not acceptable. When I enable Xinerama for my setup, gnome-panel no longer spans two monitors, and applications maximize as expected, but compiz does not work, as X11 compositing is not available. The lack of desktop compositing causes problems with dragging windows between screens (redraws take forever). Is there anything I can do to fix these issues without opting for different graphics cards?

  • Why do I have Unity and GNOME Classic running at the same time?

    - by jerowin
    I've recently updated and found that Unity shows on the gnome-classic/fallback desktop. Is this a new feature (which I doubt to be), or a bug? If it is a bug, tell me how to disable Unity because it interferes with the lower panel (i.e. I bring out Trash instead of showing the desktop when I try pressing the "Show desktop" button when the panel is not in focus). I don't encounter this problem in gnome-classic (No effects). Don't judge me. I like pokemon!

  • Many ui panels needs interaction with same object

    - by user877329
    I am developing a tool for simulating systems like the Gray-Scott model (That is systems where spatial distribution depends on time). The actual model is loaded from a DLL or shared object and the simulation is performed by a Simulation object. There are at least two situations when the simulation needs to be destroyed: The user loads a new model The user changes the size of the domain To make sure nothing goes wrong, the current Model, Simulation, and rendering Thread are all managed by an ApplicationState object. But the two cases above are initiated from two different UI objects. Is it then ok to distribute a reference to the ApplicationState object to all panels that need to access at least one method on the ApplicationState object? Another solution would be to use aggregation so that the panel from which the user chooses model knows the simulation parameter panel. Also, the ApplicationState class seems somewhat clumsy, so I would like to have something else

  • List of Application indicators

    - by user8592
    I installed Ubuntu 11.04 on one of my systems and I am using Unity interface. Unity is working quite nice so far but i really miss panel applets for net speed, cpu temp, and system monitor. These applets show useful quickinfo. Unlike 10.10, there is no other way to get these infos onto the panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look. If you know then please list out any third party indicators with links so that they can be found at one place.

  • Down to the Wire - Yet More Solaris Things to See at OpenWorld (and JavaOne!)

    - by Larry Wake
    San Francisco is bracing for the annual invasion. The airport's jammed, the tweets are flying, and the numbers are crazy: more than 50,000 attendees and 2,500+ sessions, taking over Moscone Convention Center, two streets, Union Square, and seemingly every hotel in town (98,000 hotel room nights). So yeah, it's busy. And it's not just OpenWorld--we've also got JavaOne, MySQL Connect, and four other sub-events going on as well. Speaking of JavaOne, you can find Solaris-related activity there, too -- I've highlighted one hands-on lab below. Here's a last pre-event roundup of activities for consideration; enjoy the show(s)! (Remember, Schedule Builder is your friend; use it with the session numbers below to register.) Monday, October 1st: 3:15 PM - General Session: Accelerate Your Business with the Oracle Hardware Advantage(GEN9691, Moscone North Hall D) John Fowler, head of Oracle's Systems organization, will talk about Oracle hardware technology and how it's co-engineered with other key technologies, including Oracle Solaris. Tuesday, October 2nd: 10:15 AM - Building an IaaS Platform with SPARC, Oracle Solaris 11, and Oracle VM Server for SPARC(CON4431, Moscone South 270)Get the birds-eye lowdown (whatever that means) on how U.S. Cellular  built its Infrastructure as a Service (IaaS) cloud delivery platform with Oracle’s SPARC T4 servers, Oracle Solaris 11, Oracle Solaris Cluster 4, and Oracle VM Server for SPARC. The session covers the high-level design, business case made, implementation details, and lessons learned. 11:45 AM - Oracle Solaris 11 Panel: Insights and Directions from Oracle Solaris Core Engineering(CON8790, Moscone South 252) This has been one of the livelier Solaris-related sessions in years past (and I'm not saying that just because I get to moderate it this year). A panel of core engineers responsible for a wide range of key Solaris technologies will talk about some of the interesting work they've been doing -- but mostly we keep time open for the panel to take questions from attendees, because that's the fun part. Wednesday, October 3rd: 10:00 AM - Tracing Your Java Application Tuning on Oracle Solaris with DTrace(HOL10214, Hilton San Francisco, Franciscan A/B/C/D) This JavaOne hands-on lab will show how to use the DTrace framework to dynamically trace your Java applications on Oracle Solaris and uncover new tuning opportunities.

  • What is the "don't force full gpu scalling" configuration in the newest Nvida driver settings?

    - by wild_oscar
    I have a Zotac Ion board on a computer running Linux ad I had the driver version 295.xx. I was trying to run a 1080 video on XBMC and, because playback was a bit sluggish, part of my (unsuccessful) attempt at making it run smoothly was to upgrade the Nvidia driver. The problem is that the computer is connected by HDMI to a Pioneer A/V system - which in turn is connected to the TV (also through HDMI). When I created this set up I didn't get any image on my tv until I Unchecked "force full gpu scaling" in "Flat Panel Scaling". After upgrading the Nvidia driver I no longer have image. Upon investigating, I saw on the release changelog: Removed Flat Panel Scaling configurability in nvidia-settings. Any desired scaling can be configured through the new "ViewPortIn" and "ViewPortOut" MetaMode attributes. I know very little about this, however, so I'm lost. What would the correct configuration be with these new ViewPortIn/Out options to achieve the same result as "unchecking force full gpu scalling"?

  • Create a Customized Tab on the Office 2010 Ribbon

    - by Mysticgeek
    Some MS Office users were put off a bit by the Ribbon feature in 2007 for being cumbersome and confusing. Today we look at a cool new feature in Office 2010 that allows you to create your own custom tabs with specific commands for easier document creation. Create a Customized Tab In our example we’re using Word, but you can create a custom tab in the other Office apps as well. To do so, right-click on the Ribbon and select Customize the Ribbon. The Word Options screen opens up and from here you can manage a lot of customization options. We want to create a new customized tab, so click on the New Tab button.   Now give it a name… Now just drag the commands you want to add from the left column over to your new custom group. You have every command available to choose from. You can select specific groups or all commands from the dropdown menu on the left. That is all there is to it…now you have your own customized tab with the commands you use most often to help you work more efficiently. In this example We didn’t add a whole lot of commands, but you can customize it with as many as you need. You can also create other tabs with different sets of commands too. When you create a customized tab in one application, it’s only going to be in that app. For example if you create on in Word, it’s not going to show in Excel as commands differ between apps. If you want a custom tab in another Office app you’ll need to create one for it. Another very cool thing you can do is export the customizations to use on another machine or pass them to a coworker. To export the customizations, go to the Customize Ribbon section and at the bottom of the right field click Import/Export then Export all customizations. Then save the file to a location on your hard drive.   To import the settings to another machine, go into Ribbon Customizations and select Import customizations file… then browse the the file you exported. You’ll be prompted to confirm you want to import he customizations… After confirming the choice now you’ll see the customization show up on the other machine. This is very handy if you work on several machines throughout the day and want to easily bring your customized tabs with you. If you find yourself using a lot of specific commands throughout the day, creating your own customized tab will help access them more quickly. If you want to test out Office 2010 it’s currently in Public Beta and can be downloaded for free.

  • Windows Workflow Foundation (WF) and things I were more intuitive

    - by pjohnson
    I've started using Windows Workflow Foundation, and so far ran into a few things that aren't incredibly obvious. Microsoft did a good job of providing a ton of samples, which is handy because you need them to get anywhere with WF. The docs are thin, so I've been bouncing between samples and downloadable labs to figure out how to implement various activities in a workflow. Code separation or not? You can create a workflow and activity in Visual Studio with or without code separation, i.e. just a .cs "Component" style object with a Designer.cs file, or a .xoml XML markup file with code behind (beside?) it. Absence any obvious advantage to one or the other, I used code separation for workflows and any complex custom activities, and without code separation for custom activities that just inherit from the Activity class and thus don't have anything special in the designer. So far, so good. Service - In the WF world, this is simply a class that talks to the workflow about things outside the workflow, not to be confused with how the term "service" is used in every other context I've seen in the Windows and .NET world, i.e. an executable that waits for events or requests from a client and services them (Windows service, web service, WCF service, etc.). ListenActivity - Such a great concept, yet so unintuitive. It seems you need at least two branches (EventDrivenActivity instances), one for your positive condition and one for a timeout. The positive condition has a HandleExternalEventActivity, and the timeout has a DelayActivity followed by however you want to handle the delay, e.g. a ThrowActivity. The timeout is simple enough; wiring up the HandleExternalEventActivity is where things get fun. You need to create a service (see above), and an interface for that service (this seems more complex than should be necessary--why not have activities just wire to a service directly?). And you need to create a custom EventArgs class that inherits from ExternalDataEventArgs--you can't create an ExternalDataEventArgs event handler directly, even if you don't need to add any more information to the event args, despite ExternalDataEventArgs not being marked as an abstract class, nor a compiler error nor warning nor any other indication that you're doing something wrong, until you run it and find that it always times out and get to check every place mentioned here to see why. Your interface and service need an event that consumes your custom EventArgs class, and a method to fire that event. You need to call that method from somewhere. Then you get to hope that you did everything just right, or that you can step through code in the debugger before your Delay timeout expires. Yes, it's as much fun as it sounds. TransactionScopeActivity - I had the bright idea of putting one in as a placeholder, then filling in the database updates later. That caused this error: The workflow hosting environment does not have a persistence service as required by an operation on the workflow instance "[GUID]". ...which is about as helpful as "Object reference not set to an instance of an object" and even more fun to debug. Google led me to this Microsoft Forums hit, and from there I figured out it didn't like that the activity had no children. Again, a Validator on TransactionScopeActivity would have pointed this out to me at design time, rather than handing me a nearly useless error at runtime. Easily enough, I disabled the activity and that fixed it. I still see huge potential in my work where WF could make things easier and more flexible, but there are some seriously rough edges at the moment. Maybe I'm just spoiled by how much easier and more intuitive development elsewhere in the .NET Framework is.

  • Home Networking Questions

    - by Eddie Parker
    Hello: I'm looking to wire my home with CAT-X (where X is probably going to be CAT-6, unless someone can convince me differently. ;) ). I'm seeking advice on what equipment I'll need for the job, and any things I should watch out for. It's a two story half-duplex I'll be wiring, roughly about 1800 sq ft. Here's what I believe I need so far: Bulk CAT-6 Ethernet cabling CM Rated Gigabit switch(es?) Patch panel Equipment for cutting, terminating wire, fishing through walls, etc Wall outlet covers, etc. Questions I have: Does it matter the MHz rating on the Ethernet cable? If so, why? I have two gigabit switches currently, an 8-port and a 5-port. Should I buy one massive switch to cover all the connections I need, or should I just chain the two together and buy a switch for however many other connections I need? Do I really need a patch panel? I understand it keeps the cables looking cleaner than coming out of a hole in the wall, but is there some other product I can use, perhaps combining a switch with a patch panel or some such? Ideally I'll have all this running out of a relatively small closet, so the less components (or smaller) the better. Any advice, links, or suggested product to use/avoid would be appreciated!

  • How do you host multiple public facing websites on a VPS?

    - by pedroarvy
    We host about 30 websites using typical shared hosting plans using ASP.NET and SQL 2000/2005/2008. I am now wondering about hosting all of these websites using our own virtual private server. This is clearly cheaper but comes with a lot of questions I need answers to: Is the risk of having to keep this VPS server up and running worth it? Until now, the host provider has managed the server and we have not had to worry about crashes, downtime, software patches etc. We are not server administrators, we are programmers, so this is not really our expertise. On the other hand, it may not be hard to learn. When we make a website live, we log in to a domain management control panel and change the primary and secondary name servers to point to our shared web host: Eg ns1.sharedwebhost.com and ns2.sharedwebhost.com These name servers are going to have to change when we have a VPS. I don’t understand anything about how to set this up. Is there some useful info anyone could direct me to? Or is there software we need to install to make the primary and secondary name servers work on our VPS? The control panel we have for shared hosting comes with DNS management like this: http://www.yart.com.au/stackoverflow/dns.png What software would I need to install to create this for each site we host at a VPS? The control panel we have for shared hosting also comes with a POP email interface that allows email addresses to be added easily by our customers. Is this something that can be easily set up at a VPS so clients can manage their own email addresses? Is there software we need to install to make this work?

  • How do I force Windows 7 to recognize my Projector?

    - by user63564
    I have a new Dell XPS with an NVIDIA GeForce GT 445M and an old (several years) Epson PowerLite Cinema 550 projector. Windows 7 refuses to recognize that the projector is connected under normal conditions (I'll get to the strange condition in a moment). Here are some things that I have already tried: Confirm that the projector continues to work well on my old Windows XP laptop. Confirm that the video cable (HDMI to HDMI) is connected Make sure the Dell laptop is plugged in to wall power at all times Reboot both the computer and the projector Click "Detect" under the "Connect to an External Display" Windows dialog (no reaction) Click "Rigorous Display Detection" under NVIDIA Control Panel (dialog: none found) Checked "Force Television Detection on startup" under "My display is not shown..." in NVIDIA Control Panel (no effect) Here's where it gets weird... My projector has three states: off, standby and on. Standby means the power switch on the back is on, but the projector is effectively off (no picture, no access to menu or controls). When I plug in the HDMI cable while the projector is in standby, Windows detects the projector! It lets me switch to Duplicate, Extend, or Project Only mode, and adjusts the resolution appropriately. A new Generic Plug-n-Play monitor shows up in my device manager. A "Seiko EPSON PJ" display shows up in my NVIDIA control panel. Then if I turn my projector on, Windows no longer recognizes the display. This is true whether I turn the projector on while the HDMI cable is plugged in, or if I unplug the HDMI cable while turning on the projector. Anyone have any ideas, because I'm completely stumped...?

  • Gmail notification in Ubuntu's native mail icon.

    - by D Connors
    So, new Ubuntu 10.04 up and running. Playing with the interface eventually got me curious about something. Up until now, I've only used the chat and broadcasting functionalities of the mail icon in Ubuntu's top panel, mostly because I take care of my mail on firefox so I don't need one more program (empathy) running on my poor little netbook. I'm currenty using gnome-gmail to set gmail as my default mail client in Ubuntu. But, when I click on the "Set up mail" item, inside the Panel's Mail icon, it simply brings up empathy. My question is: Is it possible (in any way whatsoever) to have my gmail notifications up there, configured so that clicking it will just take me to a gmail tab in Firefox? (instead of opening up empathy) This is really just some frivolous interest of mine, nothing important. Right now I'm using check-gmail to notify me of new mail, but the panel is really cramped up on my netbook, so it'd be nice to free up some room by getting rid of check-gmail and only using Ubuntu's mail icon. Ok, hope I was clear enough.

  • Why does USB thumb drive screw up boot sequence?

    - by Carl B
    I am looking for understanding to a boot issue. I have at times had some files and such that I save and retrieve from my thumb drive. I use the front panel as it is nice and easy to get to and I typically power down my system nightly. If I forget to pull the drive and power on the system, it becomes the first bootable device. As there is no OS on the USB Drive I get the BOOTMGR is missing press CTRL+ALT+DELETE. When I go into BIOS to see Boot sequence, there’s the thumb drive up top, DVD drive is missing and not found in the list of devices. All of the hard drives are next in line. When I pull the USB drive, and reboot, everything is back to normal. Old boot sequence is in place, DVD drive right where it should be and no issues. So why does this happen with a USB drive in port at boot up? If it can’t be booted from, shouldn’t the next drive be attempted? Note: This happens when the thumb drive is plugged into a USB port on the front panel. It does not seem to happen on rear panel ports.

  • dns configuration error in plesk

    - by Karthik Malla
    I purchased a domain www.softmail.me at Godaddy.com and tried it DNS and getting lots of errors and finally change my nameservers to my server DNS i.e. NS101.VPSLAND.COM and NS202.VPSLAND.COM and created a domain in my plesk panel (Marked DNS & Mail required). After adding my domain to my plesk panel of my server I opened DNS records of that domain and found DNS records are automatically generated to my needs as following 65.75.241.26 / 24 PTR softmail.me. ftp.softmail.me. CNAME softmail.me. lists.softmail.me. CNAME softmail.me. mail.softmail.me. A 65.75.241.26 mssql.softmail.me. A 65.75.241.26 ns.softmail.me. A 65.75.241.26 sitebuilder.softmail.me. A 65.75.241.26 softmail.me. NS ns.softmail.me. softmail.me. A 65.75.241.26 softmail.me. MX (10) mail.softmail.me. webmail.softmail.me. A 65.75.241.26 www.softmail.me. CNAME softmail.me. Finally I waited for a week for I am unable to use my domain. Also in DNS lookup I cannot find any records to my Server except name servers of VPSland. Do I need to add VPSland namesevers anywhere in Plesk panel? If so where? Can anyone assist me where the mistake is?...
