  • Using terminal vs KDE in linux?

    - by Ke
    Hi Im used to using nautilus within centos but have recently just got a VPS and quickly realising that using a KDE is unacceptable in this environment. Although I do find it so much quicker doing things like folder permissions in KDE rather than typing it all out in the terminal? Everyone I speak to says, use the terminal and I should learn this way as opposed to using the KDE, but theres certain things I just dont get How is it possible to make quick changes to scripts and viewing them in a browser etc , without a mouse or using KDE? and only using a terminal?? I am wondering how to develop websites just using the terminal??? How can it be quicker to type out/view permissions etc in the terminal when its instant and just a few clicks in the KDE? Any thoughts are much appreciated. I would love to understand the benefits but just cant seem to see them right now. Cheers Ke.

  • Debugging asp.net with firefox and visual studio.net - very slow compared to IE

    - by john
    Debugging asp.net websites/web projects in visual studio.net 2005 with Firefox is loads slower than using IE. I've read something somewhere that there is a way of fixing this but i can't for the life of me find it again. Does anyone know what i'm on about and can point me in the right direction please? Cheers John edit sorry rob i haven't explained myself very well(again). I prefer Firefox for debugging (firebug etc) hitting F5 when debugging with IE the browser launches really quickly and clicking around my web application is almost instant and when a breakpont is hit i get to my code straight away with no delays. hitting F5 when debugging with FireFox the browser launches really slowly (ok i have plugins that slow FF loading) but clicking around my web application is really really slow and when a breakpoint is hit it takes ages to break into code. i swear i've read something somewhere that there is a setting in Firefox (about:config maybe?) that when changed to some magic setting sorts all this out.

  • Oracle .NET Provider DLL hell

    - by Pablo Santa Cruz
    I am currently developing on a Win7-32bits computer. Everything works fine. It's a ASP.NET application. I was able to use Microsoft's Oracle deprecated .NET provider to connect to Oracle (using 32 bit instant client) and also ODP.NET. No problems at all. Application runs fine. The problem comes when I deploy it to IIS7 on Windows 2008 Server 64bit computer. I can't get Microsoft's deprecated .NET provider or ODP.NET to work easily. Is there a straightforward way to use a 32bit based ODP.NET or Microsoft's Oracle deprecated .NET provider in Windows 2008 Server 64bits? DLL hell here! Thanks.

  • How can I enjoy or avoid designing every web application I make ?

    - by schmrz
    I know this sounds silly, but I'm having huge problems (ok, not that huge, but still...) problems when I get an idea for a web project, small or big. The instant turn off is when I remember that I have to code the html/css by hand again and again. I like programming a lot more that designing web sites, and I simply don't enjoy designing them as much as I enjoy programming them. With that said, I also prefer simple and minimalistic designs. What is your approach in web design, how do you make it enjoyable (at least a little bit)?

  • Constant expression with custom object

    - by nils
    I'm trying to use an instant of a custom class as a template parameter. class X { public: X() {}; }; template <class Foo, Foo foo> struct Bar { }; const X x; Bar<X, x> foo; The compiler states that x cannot appear in a constant expression. Why that? There is everything given to construct that object at compile time.

  • UISlider returns two Touch Up Inside events, why does that happen?

    - by willc2
    I have a slider that I'm using to set a float value somewhere. I connect Value Changed to a method in my viewController. That part works fine. I need to know when the user starts touching the control but not necessarily every single instant that the slider changes (I receive the Value Changed events for that). So I connected a Touch Up Inside event to another method in the viewController. The problem it, that method gets called twice when the user touches the UISlider control. WTF? It doesn't work that way with UIButtons or other touch events like Touch Down. I can work around it, I think, but it seems like a bug in the way the slider control handles touches. Does anybody know why it happens? BTW: the double touch event happens even when Touch Up Inside is the only connected event.

  • Avoid painting over nested controls

    - by Cobus Kruger
    I am writing a toolbar-style control and use the ThemeServices unit to paint the background required by the toolbar. Like so: ThemeServices.DrawElement(Canvas.Handle, ThemeServices.GetElementDetails(trRebarRoot), ARect); I then drop child controls onto the toolbar and voila - instant toolbar. Except that every now and again I notice that the nested (child) controls don't repaint as well. So my control paints its background and the child controls disappear until you move the mouse over them. Some of the edit controls show their client area (no border) and some of them are just gone altogether. This happens mostly when I place a window from another application over the toolbar and move it away. I keep thinking this has to be very easy to cure, that perhaps I'm somehow preventing the paint message from reaching the child controls, or missing an override but I have been unable to figure it out.

  • C# Training Quizzes

    - by John Sheppard
    Hello there, I have been programming 10 years, mostly in vba and vb.net but I know c# well enough to program what I normally do. I yesterday was applying for a Senior c# position and I did so poorly on the induction test its not funny :) I have always found that for me the best way to learn and recall is via question's and answers (multichoice and short answer). That is, a question is posed and after I answer instant feedback is given as to whether I choose right or wrong and the reasons why. As such I was wondering if anyone knew of or could recommend a C# quiz website. Something like a daily c# quiz to keep my brain up to date and fresh if I'm not always programming in it. Not something wimpy either. Something that does everything. Paying is not an obstacle, id prefer to pay for a good resource than muck around. Thank you

  • When to use MVP in Windows Forms .net application?

    - by Janalopa
    I am familiar with MVC/MVP though my question is simple, I'm about to program a simple Instant Messaging software when the engine and communication part is an open API. so my software will have about 3 forms, a splash screen with login details, the options form and a main form with all the functionality like: Friends List, Send message, Received messages (tabbed), search user, etc. In UI perspective, its important for the GUI to be in 1 form in my application. So my question is, for the only complicated form that I'm going to have, is it necessary to implement an MVP design pattern or in this case its better to just go straight forward and put all the logic in 1 place? THANKS Janalopa!

  • Speed up dialog/page transitions in jQuery Mobile on iPhone?

    - by Crashalot
    There are other SO questions on speeding up jQuery Mobile for Android, but does anyone know how to accelerate page transitions on iPhones, specifically dialog transitions? We're on JQM 1.0. JQM 1.1 is supposed to speed up page transitions (though we haven't seen any demos yet), but we're wondering if anyone has done anything for JQM 1.0. Right now, there is a two second delay, which is too much to show a dialog. We resort to one of two options. Using no animation for the page transition, which provides instant feedback, or rolling our own by binding to "touchstart" and animating the dialog, which is really just a big DIV inside the current page. Neither is ideal. Suggestions?

  • Scapy PcapReader and packets time

    - by auino
    I'm reading a PCAP file using Scapy using a script such as the (semplified) following one: #! /usr/bin/env python from scapy.all import * # ... myreader = PcapReader(myinputfile) for p in myreader: pkt = p.payload print pkt.time In this case the packets time is not relative to PCAP capture time, but starts from the instant I've launched my script. I'd like to start from 0.0 or to be relative to the PCAP capture. How can I fix it (possibly without "manually" retrieving the first packet time and repeatedly using math to fix the problem)?

  • review on django book vs django tutorial

    - by momo
    going through both the django book and tutorial, am a bit confused to the differences in approach (aren't they both written by the same people?) can anyone who has experience in both give a short review on them? i have decent python skills (largely untested though), but no experience at all in web apps and am trying to decide which one to stick to. i briefly looked in to practical django projects but that was a bit too complicated for me, my background is primarily bash scripting, the python i know i learned from an instant hacking tutorial and diving into python.

  • Prevent users from being able to access a webpage via web browser?

    - by Rob
    My friend and I are working on a program. This program is going to submit GET data to our webpage. However, we don't want users accessing the webpage any other way than the program. We can prevent users from sharing the program using HWID authentication, but nothing prevents them from using a packet scanner to get the URL of the webpage. We thought about user-agent authentication, which we will implement, but user-agents can easily be spoofed. So my question is, how can we prevent users from accessing the webpage directly, instead of through the program? Even if you don't have an answer that will completely work, anything that will help deter them would be nice. Currently we will be implementing: HWID Authentication to use the program User-Agent Authentication to access the web page Instant IP Blacklisting to anyone accessing the webpage without the proper User-Agent

  • XmlSerializer Performance Issue when Specifying XmlRootAttribute

    - by Dougc
    I'm currently having a really weird issue and I can't seem to figure out how to resolve it. I've got a fairly complex type which I'm trying to serialize using the XmlSerializer class. This actually functions fine and the type serializes properly, but seems to take a very long time in doing so; around 5 seconds depending on the data in the object. After a bit of profiling I've narrowed the issue down - bizarrely - to specifying an XmlRootAttribute when calling XmlSerializer.Serialize. I do this to change the name of a collection being serialized from ArrayOf to something a bit more meaningful. Once I remove the parameter the operation is almost instant! Any thoughts or suggestions would be excellent as I'm entirely stumped on this one!

Do you know any way to avoid it? thanks

  • Using mozilla plataform to develop desktop applications

    - by RHaguiuda
    Hi everyone. From what It seems mozilla plataform was designed to be used focused in web development (browsers, e-mail clients, instant message...). I want to use Mozilla plataform to develop desktop applications that need most access to computer serial port and some applications that have nothing to do with web. Im considering mozilla because its multi-plataform and easy to extend using themes and extensions. Is it possible to program a serial terminal for example using mozilla? Does mozilla have any class ou framework that do this job or I`ll have to code for windows API? Thank you!

  • how random is Math.random() in java across different jvms or different machines

    - by user881480
    I have a large distributed program across many different physical servers, each program spawns many threads, each thread use Math.random() in its operations to draw a piece from many common resource pools. The goal is to utilize the pools evenly across all operations. Sometimes, it doesn't appear so random by looking at a snapshot on a resource pool to see which pieces it's getting at that instant (it might actually be, but it's hard to measure and find out for sure). Is there something that's better than Math.random() and performs just as good (not much worse at least)?

  • Help with replacing Mac factory install of apache with MAMP PRO so FileMaker will work with my other

    - by tannerSF
    I am running Mac 10.4 and have been using MAMP PRO to host several websites I manage. Now that I have installed FileMaker Pro Server, it forces me to turn Web Sharing on in System Preference. So is it possible to either replace Apache with MAMP PRO's version? Or is it possible to get FileMaker Pro to use MAMP instead of Web Sharing? If so, how can I make it happen? Also, with FileMaker Instant Web Publishing, how , how can I make my domain link directly to where FileMaker publishes it? So what I want to be able to do is type http:///mydomain.com and it direct to mydomain.com:591/FMI/IWP/

  • How do I backup my C++ Builder component installation?

    - by Gary Benade
    Hi I finally have my c++ Builder 2010 installation the way I want it, with all my components upgraded and installed. (touch wood) I have been working with c++builder since version 1 and I know from countless previous traumatic experiences that this state of affairs could change in an instant. I would like to backup the installation and component set. Is there a way to do this? A tool perhaps? A menu command that I have maybe missed all these years? I don't want to have to reinstall all the components from the bpl source again. I make nightly backup images of my entire drive, I would like to do this for c++builder only if possible. If it's a matter of simply copying files, which files would I need to copy? Are there entries in the registry that would need to be restored? Thanks in advance for any thoughts and suggestions

  • Open a chrome tab from delayed javascript window.open

    - by jettero
    When I window.open("http://blarg") in chrome, I get a new tab. If I delay the open, say using a jquery $(hrm).animate({},5e3,function(){window.open(url)); it opens the url in a new window with no status bar, etc — if I give it permission to pop-up that is. I'm looking for a way to get the instant behavior, that is, I wish to open a URL after an animation, but still in a new tab. I imagine I could get by with learning a way to instruct chrome to never ever open pop-ups and to always open them in tabs (I imagine there's a webkit setting, why it's not a built in is a mystery); but I'd rather try to find a way to do it from the javascript if possible. I somewhat doubt there's any way to do this though. I'm not aware of any javascript that's tab-aware.

  • jQuery color plugin: onMouseOver animation causes flickering in FF3.5.5

    - by rt-uk
    I'm trying to change the background color of a div on mouseover and mouseout. Instant change to yellow on MouseOver, and slow fade on MouseOut. function hilightel(keydiv) { $('#'+keydiv).animate({ backgroundColor: '#ffffd3' },1); } function lolightel(keydiv) { $('#'+keydiv).animate({ backgroundColor: '#ffffff' },300); } < div onMouseOver=javascript:highlightel('item1'); onMouseOut=javascript:lolightel('item1'); id='item1'CONTENT< /div When the mouse moves over text within the div, though, it thinks I've moused-out and so flickers badly. Alternatives that don't work: - animateToClass doesn't support background-color so I'm using the 'color' plugin - I hear that switchClass doesn't work in Chrome - Can't use .hover because their will be dynamically named divs in the page so need a general function Thanks in advance...

  • Should you restrict developers internet access?

    - by Craig HB
    Our (small to medium-sized) company is going to start enforcing an internet policy which everyone, including the team of 4 senior developers, will be subject to. Amongst other things, this means that developers will not be able to access: web based e-mail (Hotmail, Yahoo, Googlemail) instant messaging accounts (MSN Messenger) social networking sites (Facebook) streaming media (internet radio) At the moment, we don't have any restrictions on our internet use, so I really want to find out what the effect on the team will be. Please let me know your thoughts. What effect do you think this will have on the team (positive or negative).

  • Articles about replication schemes/algorithms?

    - by jkff
    I'm designing an hierarchical distributed system (every node has zero or more "master" nodes to which it propagates its current data). The data gets continuously updated and I'd like to guarantee that at least N nodes have almost-current data at any given time. I do not need complete consistency, only eventual consistency (t.i. for any time instant, the current snapshot of data should eventually appear on at least N nodes. It is tricky to define the term "current" here, but still). Nodes may fail and go back up at any moment, and there is no single "central" node. O overflowers! Point me to some good papers describing replication schemes. I've so far found one: Consistency Management in Optimistic Replication Algorithms

  • Is it Me or Are Rails and Django Difficult to Install on Windows?

    - by Mackristo
    I tried getting these frameworks working on Windows Vista for a couple of days but to no avail. Every single time I thought I had them working I would get some random error involving the PostgreSQL or MySQL setup, or the paths were screwed up or some other command line error "not recognized as an internal or external command" (or something). Someone told me that these frameworks are a lot easier to get running on Ubuntu but I really don't want to make that switch as everything I have is on Windows. Are these common problems when trying to get running on Windows? I think I'll just stick with C# and .NET as everything seems to work pretty nicely together with none of this "install-twenty-different-components" stuff and see if they work together. Is Instant Django advisable to use?

  • Can I send a variable to paypal, and have it post it back to me when payment completes?

    - by Yegor
    Ive been using express checkout API to convert people's accounts on my site to premium accounts after paying. The only problem with it is that it doesn't send the user back to the site until they click the button to return, and it updates their permission when that happens. About 40% of the users don't seem to do that.... so their accounts never get credited after payment. Although paypal does an instant post-back upon the successful payment, I was never able to make it actually update the user's account right away, since I cant get it to send back some sort of informational that would identify the user that just completed the payment. I could only do that when you are sent back to the site, which sends the transaction ID, that I logged with a post-back. It searches for it, and grants permission if it was found int he DB. Is there a way to submit some sort of a variable to paypal, that it will then post back to me? Something like &user_id=123, which would make it very handly to update the user's permission.
