  • Elastix, how to MOVE files from one server to other server?

    - by yudayyy
    In my office, i have to schedule for moving a file from one computer to other computer (Both are using Elastix). My idea is using cron, scp, and rm to do this. So here are the script that i use: scp -r /home/data/* [email protected]:/home/data1 && rm -r /home/data/* That script did the copy, but not remove the source file. I already read this question: Hov to _MOVE_ files with scp? The problem is, the computer doesn't have an internet connection. So i cannot install rsync on my elastix computer. yum install rsync Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile and then it freezes. Any idea how to do this?

  • How to get xy coordinates along a given path

    - by netbrain
    Say i have two points (x,y), (0,0) and (10,10). Now i wan´t to get coordinates along the line by stepping through values of x and y. I thought i solved it with the following functions: fy = startY + (x - startX) * ((destY-startY)/(destX-startX)); fx = (y + startY) / ((destY-startY)/(destX-startX)) + startX; taken from http://en.wikipedia.org/wiki/Linear_interpolation However, it seems that im getting a problem when destX and startX is the same value, so you get division by zero. Is there a better way of getting coordinates along a line when knowing the start and endpoint of the line?

  • hp laserjet 4200 madness

    - by C-dizzle
    I have an HP LaserJet 4200 printer that is acting really weird. I can print from internet just fine, no problem... but when I try to print from a document used in microsoft word, for example, I always get "Manual Feed Tray 1". I have racked my brain on this and cannot get it figured out. It's a networked printer and only an administrator account can make changes to it, I have also reset the printer back to factory settings, uninstalled and reinstalled onto the pc's and server it is connected to. Running out of hair since I'm pulling it all out... please help.

  • FastCgiModule Error 500 on Windows7 Ultimate + IIS 7.5

    I'm running IIS 7.5 on Windows 7 Ultimate. I've installed PHP Version 5.2.14 using Microsoft Web Platform Installer.

  • Navigate Quickly with JustCode and Ctrl+Click

    Ctrl + Click is a widely used shortcut for Go To Definition in many development environments but not in Visual Studio. We, the JustCode team, find it really useful so we added it to Visual Studio. But we didn't stop there - we improved it even further. Read on to find the details. With JustCode you get an enhanced Go To Definition. By default you can execute it in the Visual Studio editor using one of the following shortcuts: Middle Click, Ctrl+Left Click, F12, Ctrl+Enter, Ctrl+B. The first usage of this feature is not much different from the default Visual Studio Go To Definition command use it where a member, type, method, property, etc is used to navigate to the definition of that item. For example, if you have this method:         public void Start()         {             lion = new Lion();             lion.Roar();         } If you hold Ctrl and click on the usage of the lion you will go to the lion member definition. If you hold Ctrl and click on the Lion you will go to the Lion class definition. What we added is the ability to easily find all the usages of the item you just navigated to. For example:     public class Lion     {         public void Roar()         {             Console.WriteLine("Rhaaaar");         }     }   If you hold Ctrl and click on the Lion definition you will see all the usages of the Lion type; if you click on the Roar method definition you will see all the usages of the Roar method: And if there is only one usage you will get automatically to that usage. In the examples I use C#, but it works also in VB.NET, JavaScript, ASP.NET and XAML. Why we like this feature? Let me first start with how the Ctrl+Click (or Go To Definition command) is used. We noticed that developers use it especially in what we call "code browsing sessions". In simple words this is when you browse around the code looking for a bug, just reading the code or searching for something. Sounds familiar? In our experience when you go to the definition of some item you often want to know more about it and the first thing you need is to find its usages. With JustCode this is just one click away. Why Ctrl+Click/Middle Click over F12/Ctrl+Enter/Ctrl+B? Actually you can use all of them. But during these "code browsing sessions" we noticed that most developers use the mouse. So the mouse is already in use and pressing Ctrl+Click (or the Middle Click) is so natural. During heavy coding sessions or if you are a keyboard type developer F12 (or any of the other keyboard shortcuts) is the key. We really use heavily this feature not only in our team but in the whole company. It saves us a bit of time many times a day. And it adds up. We hope you will like it too. Your feedback is more than welcome for us. P.S. If you dont want JustCode to capture the Ctrl+Click and the Middle Click in the editor, you can change that in JustCode->Options->General in the Navigation group. Keyboard shortcuts can be reassigned using the Visual Studio keyboard shortcuts editor.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • How are Programming Languages Designed?

    - by RectangleTangle
    After doing a bit of programming, I've become quite curious on language design itself. I'm still a novice (I've been doing it for about a year), so the majority of my code pertains to only two fields (GUI design in Python and basic algorithms in C/C++). I have become intrigued with how the actual languages themselves are written. I mean this in both senses. Such as how it was literally written (ie, what language the language was written in). As well as various features like white spacing (Python) or object orientation (C++ and Python). Where would one start learning how to write a language? What are some of the fundamentals of language design, things that would make it a "complete" language?

  • sharepoint 2007 access denied when accessing user profiles via ssp

    - by user22215
    Guys I have a really strange problem in regards to sharepoint mysites today I go into user profiles and properties in order to setup a property all of a sudden I get access denied. First off I know that I'm logged in with the correct account after the access denied I decided to click on personalization services and permissions I than get An unhandled exception occurred in the user interface.Exception Information: Cannot complete this action. I'm not seeing anything in the server application logs either. So have any of you guys seen this before is there some kind of way to grant a user account the manage profiles right permission using stsadm. BTW all other fucntions of the ssp are working fine so my question is if the user profiles and my sites of a ssp tanks how do you repair that portion of the ssp? BTW the user accounts that I'm using are site collection owners and also they have full control at the web application level. I actually ran across this interesting post but this does not really help my problem. http://blog.tylerholmes.com/2008/09/access-denied-for-site-collection.html

  • Any tips to learn how to program with severe ADHD?

    - by twinbornJoint
    I have a difficult time trying to learn how to program from straight text-books. Video training seems to work well for me in my past experiences with PHP. I am trying my hardest to stay focussed and push through. Specifically I am looking to start indie game development. Over the last two weeks I have been trying to pick the "right" language and framework to develop with. I started going through Python, but I am not really enjoying the language so far. I am constantly looking through this website to compare this language to that, and keep getting distracted. Aside from all of this, is it possible to become a programmer when you have trouble focussing? Has anyone been through this that can recommend some advice? edit - you guys can check my new question out with detailed information thanks to all of the responses from this thread. http://programmers.stackexchange.com/questions/15916/what-is-the-best-language-and-framework-for-my-situation

  • Why Outlook 2007 pasted images are larger than original?

    - by Jersey Dude
    I have been using Outlook 2007 for over a year with no image problems. Around September 1st, images that I paste into messages are enlarged in the messages. This happends with WinSnap, the Vista Snipping Tool, or any jpeg pasted into the message I tried jpegs with 96dpi settings w/o sucess I tried different Outlook Format Picture ... and Size ... settings Problem happens with both RTF and HTML messages Attached images are ok Something mysteriously changed and I cannot figure it out. I googled this to death without any success (others have the problem but there is no solution). This is driving me nuts because I snap screenshots all day long ("a picture is worth a thousand words"). Thanks in advance.

  • What does SVN do better than git?

    - by doug
    No question that the majority of debates over programmer tools distill to either personal choice (by the user) or design emphasis, i.e., optimizing design according to particular uses cases (by the tool builder). Text Editors are probably the most prominent example--a coder who works on a Windows at work and codes in Haskell on the Mac at home, values cross-platform and compiler integration and so chooses Emacs over Textmate, etc. It's less common that a newly introduced technology is genuinely, demonstrably superior to the extant options. I wonder if this is in fact the case with version-control systems, in particular, centralized VCS (CVS, SVN) versus distributed VCS (git, hg)? I used SVN for about five years, and SVN is currently used where I work. A little less than three years ago, I switched to git (and gitHub) for all of my personal projects. I can think of a number of advantages of git over subversion (and which for the most part abstract to advantages of distributed over centralized VCS), but I cannot think of one contra example--some task (that's relevant and arises in a programmers usual workflow) that subversion does better than git. The only conclusion I have drawn from this is that I don't have any data--not that git is better, etc. My guess is that such counter-examples exist, hence this question.

    Now let's create the start of a CRUD application on the NetBeans Platform, using Hibernate and PostgreSQL to do so. Here's what I see in NetBeans IDE after setting things up as outlined yesterday: The NetBeans Platform CRUD Tutorial should get you up and started creating the NetBeans Platform application. Open the generated "persistence.xml" in Design mode and then switch the persistence library to Hibernate.

  • Internal Server Error when using eForm with ModX

    - by Austin
    One of our clients is using modx v.0.9.6.3 with eForm. They also have their own exchange server and web hosting is done through us. We used the eForm v.1.4.4.5 to send out emails. However, they cannot get any emails from this form and when addressed to [email protected] it instantly gets to 500 Internal Server Error when the form is submitted. Note: the eForm is successfully sent when the receiver is anyone but the client. I have successfully received the email form report from a work email, and also personal email.

  • port forwarding using 3 static ip addresses

    - by Danny
    I am new to configuring routers. We have purchased a RV016 Cisco business router that has multiwan capability. What we are attempting to do is take map services from 3 different servers and assign 3 different static IP addresses and then forward port 80 through the router. A short term solution to building a proxy server. Is this possible? Right now we have a consumer grade Cisco router and assign a static IP and it works, we attempted the same settings on the business router and cannot get to the internet. We set it DHCP and it works fine, however we want to to forward the static ports not use DHCP.

  • Enterprise laptop doesn't recognize WiFi

    - by Michiel
    My cousin is using an enterprise laptop for home work, but for some reason she can't connect to her home WiFi. The laptop isn't able to detect any WiFi networks, although she used to be able to detect and connect to the network. Whenever I troubleshoot for possible issues, Windows Vista is telling me the switch for wireless reception is turned off, but I'm sure it's turned on (If I turn it on, the HP Wireless Assistant tells me it's turned on, so...). But if I take a look at the settings, I get this message (sorry it's in Dutch): So for some reason, the WLAN reception is deactivated and I cannot activate this... Does this have something to do with the laptop being an enterprise laptop? Or is there a simple setting I missed? The most recent driver of the Wireless Network Card (Intel Wireless 5100) is installed.

  • Creating a file server - How can I use a large VHD file in Hyper-V? (700GB)

    - by barfoon
    Hey everyone, After a few discussions (here, here, and here), I am still unable to create a simple VM that will be used as a fileserver hosted on my Hyper-V box. I have created a fixed 700GB SCSI drive (.vhd file), as I have learned an IDE drive of this size is not possible. Not to sound too cynical, but its blown me away at how much trouble its been to create a large amount of space and start using it. What is the best way to create a fileserver with a drive of this size hosted on Hyper-V Server 2008, and how can I get it going??? Inclusion of OS, driver, integration tools etc, anything you feel is required would be greatly appreciated. Extra information I am using the stand-alone version of Hyper-V server, and not Windows Server 2008. I have tried loading the Linux Integration Tools (linked in the comments of the last link above) onto a SUSE 11 VM and the installation fails, the machine cannot see the vhd at all. Thanks very much,

  • How can I make the icon font color on a windows 7 prof desktop work?

    - by naxa
    I have C:\Windows\Web\Wallpaper\Scenes\img25.jpg as wallpaper (I think it's a standard windows wallpaper.) The desktop icon font color is white. It cannot be read without heavy eye pain. I want it to be black. I couldn't change the icon font color in advanced properties (ie the good old window color settings dialog) for aero for windows 7 professional x32. I've heard that the icon font color should change automatically to suit my needs, it doesn't work as advertised in my scenario. How could I fix it and rescue my eyes from popping out? EDIT screenshot attached. sorry for bad english.

  • Text box select issue

    - by Kent Boogaart
    I have this issue where the entire text in text boxes is selected whilst I'm typing in it. For example, in FireFox search box I'd try to type "foo" but end up with "o" because I managed to type "fo" before everything was selected, and then typed "o" which replaced the "fo". When it happens, it is incessant - not just a one-off. But it doesn't happen all the time, and I haven't managed to figure out what causes it to start and stop. Is this a known problem with an easy solution? EDIT: this has nothing to do with touchpad. I get this occasionally even on a machine without one. I can usually rectify the issue just be alt-tabbing about a few times.

  • Is there a name for this use of the State design pattern?

    - by Chris C
    I'm looking to see if there is a particular name for this style of programming a certain kind of behavior into a program. Said program runs in real time, in an update loop, and the program uses the State design pattern to do some work, but it's the specific way it does the work that I want to know about. Here's how it's used. - Object Foo constructed, with concrete StateA object in it - First loop runs --- Foo.Run function calls StateA.Bar --- in StateA.Bar replace Foo's state to StateB - Second loop runs --- Foo.Run calls StateB.Bar - Third loop runs --- Foo.Run calls StateB.Bar - Fourth loop --- etc. So in short, Foo doesn't have an explicit Initialize function. It will just have Run, but Run will do something unique in the first frame to initialize something for Foo and then replace it with a different action that will repeat in all the frames following it- thus not needing to check if Foo's already initialized. It's just a "press start and go" action. What would you call implementing this type of behavior?

  • What failure can kill a long running IRC client? [closed]

    - by Xeoncross
    I have an IRC bot that I built in PHP using sockets that attempts to run forever and (if disconnected) reconnects again. I have it listening to several channels. Apparently it's fairly resilient, because it can run for several days before the process ends and CRON has to start it up again. However, based on the fact the process ends I'm assuming there are other conditions I'm not accounting for that are causing problems. I have nothing in my error logs giving me a hint. In addition, sometimes the process will continue running - but I notice it's no longer present in any of the channels on the IRC server which makes me think it violated some part of the protocol. I have logic setup to handle: reply to PING's correctly reconnect on disconnect (and reconnect to channels) respond to private messages (so someone doesn't ban it) prevent memory leaks What other failure could be killing my long-running IRC client?

  • 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.

  • What caused you to stop using UML tools on your team?

    - by jamie
    There seems to be plenty of good, free UML tools. I hear about UML tools being used by large organizations, and they seem to have plenty of advocates. However, in my career I have never seen them used beyond "dabbling". Now, I have seen many UML diagrams drawn on whiteboards, and I use them myself all the time, on paper, to think about problems. I've also seen articles such as this one claiming why developers don't use UML, but the arguments just don't land with me. Frankly, this seems like an opportunity for a start-up if one can figure out why developers really don't use them, and solve those problems. So I'm asking anyone here who has attempted to use UML tools in a team, and stopped, this question: "why did you stop?" I'm especially interested in experience from agile teams. I am looking for concrete experience, not hypothetical opinion. Thanks.

  • PyQt design issues

    - by Falmarri
    I've been working on a my first real project using PyQt lately. I've done just a little bit of work in Qt for C++ but nothing more than just messing around. I've found that the Qt python bindings are essentially just a straight port of C++ classes into python, which makes sense. The issue is that this creates a lot of messy, unpythonic code. For example if you look at QAbstractItemModel, there's a lot of hoops you have to go through that forces you to hide the actual python. I was just wondering if there's any intention of writing a python implementation of Qt that isn't necessarily just a wrapper? Either by Nokia or anyone else? I really like Qt but I would love to be able to write more pythonic code. I hope this is OK to ask here. I'm not trying to start a GUI war or anything.

  • Design for future changes or solve the problem at hand

    - by Naveen
    While writing the code or during design do you try to generalize the problem at the first instance itself or try to solve that very specific problem. I am asking this because, trying to generalize the problem tends to complicate the things (which may not be necessary) and on the otherhand it will be very difficult to extend the specific solution if there is a change in the requirement. I guess the solution is to find the middle path which is easier said than done. How do you tackle this type of problem ? If you start generalizing it at what point of time you know that this much of generalization is sufficient ?

  • Java JRE: Setting default heap size

    - by AndiDog
    I'm having trouble with Java on a virtual server, it always gives me the following error: # java Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I first solved this by using the CACAO virtual machine (of OpenJDK, by putting it first in jvm.cfg), but then I run into problems with my web application (Play! framework based, gives me nasty LinkageErrors). So I cannot use that VM. Instead I'd like to just use the normal server VM and set -Xmx128M by default. How can I do that? Related: this question
