  • Ubuntu - connecting 3rd monitor fails with "xrandr: cannot find crtc for output DVI-0"

    - by MDCore
    I've got a laptop with a DVI and VGA output on the back. With everything connected it will only allow me to run 2 of the 3 monitors e.g. laptop display + VGA or DVI+VGA but not all 3. xrandr says I have 2 CRTC's, 0 and 1. The internet says I should be able to share a CRTC if the modeline is the same, and my 2 external monitors are the exact same make and model. How do I convince the software to drive all this hardware?

  • Running programs in cache and registers

    - by OSX NINJA
    In my operating systems class we were shown a picture depicting a hierarchy of memory starting from most expensive and fastest at the top and least expensive and slowest at the bottom. At the very top was registers and underneath it was cache. The professor said that the best place to run programs is in cache. I was wondering why programs can't be run in registers? Also, how can a program load itself into cache? Isn't the cache something that's controlled by the CPU and works automatically without software control?

  • Load balance between two virtual directories on a single machine running IIS6

    - by Emil Lerch
    I'm trying to simulate a production environment using a single VM. The production environment will have 3 servers behind a load balancer with sticky sessions. Production will be using IIS6. For development, I have no need to distribute load, but I want to make sure the team does not write code that relies on a single-server module. I have been hoping to set up two virtual directories and find some isapi filter to perform some rudimentary software load balancing, but I've been unable to locate anything suitable. isapi_rewrite comes close but there's no ability for a random rewrite. I don't even need sticky sessions since the application does not (in theory) rely on them. Is there something easy/free to do this, or am I stuck with multiple VMs and a NLB setup (which seems like total overkill)?

  • Is there a simple Load Balancer app for development environment on Windows?

    - by djangofan
    Does there exist a simple Load Balancer app for development on Windows? I am running a pair of JBoss 5.x instances in a cluster on a single machine. Normally , this configuration is load balanced by a nice hardware load balancer but I am wondering if there is a simple piece of software to enable load balancing in my Eclipse dev environment. Basically, for example, I want a load balancer running on port 11111 that round-robins between the 2 clustered JBoss instances on ssl ports 8443 and 8543 . (or http port if thats not possible) I know that Glassfish has a built-in load balancer but I can't use Glassfish. One idea I have is to try to setup a separate instance of Tomcat with the "balancer" web app. Im trying that now... not sure if it will work... and its a complicated setup and I wish there was something really easy.

  • How to optimize sandboxie for faster application loading

    - by user23950
    I'm referring to this one: http://www.sandboxie.com/index.php?DownloadSandboxie Do you know of any alternatives that might be better than this software. And if you don't know of any alternative. Can you show me how can I make it faster to load firefox. Or any other browser. Because it really makes application incredibly slow at loading when you run them inside a sandbox. I've also seen lots from here: http://superuser.com/questions/57129/alternative-to-sandboxie-for-64-bit-systems Do you know of any other?

  • resize image without image quality reduction

    - by ali
    In web design , it's usually needed to design an image for example in Photoshop and then use multiple sizes of it. but I don't understand something here : When I resize the image (PNG or JPG) and reduce the dimensions of that in Photoshop , the image quality extremely gets reduced and the edges become messy while resizing the image in a simple software like Microsoft Paint gives a really better output! So what's the reason ? Is there a trick in Photoshop for image resizing which I've missed? Thanks for your help. UPDATE: I resize in this way : image image size , then enter new dimensions , all of checkboxes are checked , and have tried all of resample modes including Bicubic sharper

  • Do out-of-office replies get sent to the return-path header?

    - by Brian Armstrong
    I always thought that the return-path header was used for bounced messages, so I have my email newsletter software setup to unsubscribe anyone whose email address replies back to the return-path email address. But recently some users started telling me their out-of-office replies where unsubscribing them. Do out-of-office replies get sent to the return-path on some email servers? I could check all emails to that address and see if they have the "message/delivery-status" content-type in one of the parts, but I wasn't sure if this was necessary.

  • public key infrastructure - distribute bad root certificates

    - by iamrohitbanga
    Suppose a hacker launches a new Linux distro with firefox provided with it. Now a browser contains the certificates of the root certification authorities of PKI. Because firefox is a free browser anyone can package it with fake root certificates. Can this be used to authenticate some websites. How? Many existing linux distros are mirrored by people. They can easily package software containing certificates that can lead to such attacks. Is the above possible? Has such an attack taken place before?

    How to create a customized version of an xp installation cd. I want a hand's off installation that will install all the themes, drivers , and applications I need without my intervention. How can I do that. I tried to make use of this software called Nlite. But when I tested the iso file using virtual box. The virtual box said that there's a certain file that cannot be copied. And by the way, before I customized the original iso image of windows xp sp3, it doesn't have the file copying problem that I mentioned above.

  • SQL Server MVP Deep Dives 2. The Awesome Returns.

    - by Mladen Prajdic
    Two years ago 59 SQL Server MVP's came together and helped make one of the best book on SQL Server out there. Each chapter was written by an MVP about a part of SQL Server they loved working with. This resulted in superb quality content and excellent ratings from the readers. To top it off all earnings went to a good cause, the War Child International organization. That book was SQL Server MVP Deep Dives. This year 63 SQL Server MVPs, me included, decided it was time do repeat the success of the first book. Let me introduce you the: SQL Server MVP Deep Dives 2 The topics in 60 chapters are grouped in 5 groups: Architecture, Database Administration, Database Development, Performance Tuning and Optimization, Business Intelligence. They represent over 1000 years of daily experience in various areas of SQL Server. I have contributed chapter 28 in Database Development group titled Getting asynchronous with Service Broker. In it I show you the Service Broker template you can use for secure communication between two or more SQL server instances for whatever purpose you may have. If you haven't heard of Service Broker it's a part of the database engine that enables you to do completely async operations in the database itself or between databases and instances. The official release of the book will be next week at PASS where there will be 2 slots where most of the authors will be there signing the books you bring. This is also a great opportunity to meet everyone and ask about any problems you may have. So definitely come say hi. Again we decided on a charity that will be supported by this book. It's called Operation Smile. They provide free surgeries to repair cleft lip, cleft palate and other facial deformities for children around the globe. You can also help them by donating. You can preorder it on at Manning Publications website or on Amazon. By having it you not only get to learn a lot, improve your skills and have fun but you also help a child have a normal life. If that's not a good cause then I don't know what it is.

  • CAPTCHA blocking for my scraping script?

    - by Surabhil Sergy
    I am working on a scraping project which involves getting web data and parsing them for further use. I have been working using PHP and CURL to make scraping scripts which crawls web data and I make use of either PHP Dom or Simple HTML DOM Parser library for these kinds of projects. On a recent project I encountered some challenges; initially I found the target website blocked my server IP such that the server could not make any successful requests to the site. Understanding these issues as common I bought a set of private proxies and tried to make request calls using them. Though this could get successful response, I noticed the script is getting some kind of blocks after 2-3 continuous requests. On printing and checking the response I could see a pop-up asking for CAPTCHA validation. I could not see any captcha characters to be entered and it also shows an error “input error: invalid referrer”. On examining the source I could see some Google recaptcha scripts within. I’m stuck at this point and I m not able to execute my script. My script is used for gathering data and it needs to go through a large number of pages periodically over the site. But in the current scenario I am not able to proceed with my script. I could see there are some options to overcome these captcha issues and scraping these kinds of sites too are common. I have been checking my script performance and responses over last two months. I could see during first month I was able to execute very large number of requests from a single IP and I was able to get results. Later I get an IP block and used private proxies which could get me some results. Later I am facing now with the captcha trouble. I would appreciate any help or suggestions in this regard. (Often in this kind of questions I used to get a first comment as, ‘Have you asked for prior permission from the target?’ .I haven’t ,but I know there are many sites doing so to get the details out of sites and target sites may not often give access to them. I respect the legality and scraping etiquettes but I would like to know at what point I stuck and how could I overcome that! ) I could provide any supporting information if needed.

  • Is it possible to retrieve lost Windows XP profile information?

    - by Simon Shaw
    I'm running Windows XP Professional on a PC which is less than a year old. About 3 months ago I got an error on boot saying windows could not find my profile. At this point it created a temp one. On this occasion I copied the temp data back into my existing profile and carried on using it. After another month it died again and, once again set me up a temp user. Each time this happens I lose everything related to my profile (desktop, start menu, etc). I ran checks on the hard disk and these suggested nothing was wrong so this seems a software issue not a disk problem. On the advice of my computer manufacturer I am now considering reinstalling Windows but just wanted to check if there's any other ideas for things I might be able to try. Any suggestions for what could be causing the problem would also be gladly appreciated.

  • syslog-ng fails to log on lxc host

    - by christian
    we are running CentOS 6 servers with multiple lxc-containers. For system logging we are using syslog-ng. After a while the syslog-ng daemon stops logging messages, but the daemon keeps running. This happens on the host and inside the containers (where another syslog-ng is running) as well. We could not find any patterns for the failure yet but we assume that it has something to do with lxc, because we don't have these problems on other hosts. We have the suspicion that these problems occur when more than on lxc-container is running and that only "new" processes can not log. We are running the following software versions: CentOS-Linux 6.4/6.5 lxc-0.7.5 syslog-ng-3.2.5 Do you have any ideas? Best regards trademesh

  • Show which modifier keys are pressed during screen recording?

    - by Jenko
    I'd like to see which modifier keys I've pressed during screen recordings so my students can understand what keys I've pressed while I click and drag. Is there any software that can do this? I'm aware that Windows 7 does this internally, if there's a way to enable it. Windows 7 When you have a Wacom tablet connected to your PC, or if you have a Tablet PC, windows shows little yellow tip bubbles whenever you press modifier keys. Any way to enable these on a normal PC? Update: I've tried starting the Tablet PC Input Service but nothing happens. The Tablet PC Settings dialog has nothing interesting either. Is there a registry setting I can tweak?

  • MyMessageBox for Phone and Store apps

    - by Daniel Moth
    I am sharing a class I use for both my Windows Phone 8 and Windows Store app projects. Background and my requirements For my Windows Phone 7 projects two years ago I wrote an improved custom MessageBox class that preserves the well-known MessageBox interface while offering several advantages. I documented those and shared it for Windows Phone 7 here: Guide.BeginShowMessageBox wrapper. Aside: With Windows Phone 8 we can now use the async/await feature out of the box without taking a dependency on additional/separate pre-release software. As I try to share code between my existing Windows Phone 8 projects and my new Windows Store app projects, I wanted to preserve the calling code, so I decided to wrap the WinRT MessageDialog class in a custom class to present the same MessageBox interface to my codebase. BUT. The MessageDialog class has to be called with the await keyword preceding it (which as we know is viral) which means all my calling code will also have to use await. Which in turn means that I have to change my MessageBox wrapper to present the same interface to the shared codebase and be callable with await… for both Windows Phone projects and Windows Store app projects. Solution The solution is what the requirements above outlined: a single code file with a MessageBox class that you can drop in your project, regardless of whether it targets Windows Phone 8, or Windows 8 Store apps or both. Just call any of its static Show functions using await and dependent on the overload check the return type to see which button the user chose.// example from http://www.danielmoth.com/Blog/GuideBeginShowMessageBox-Wrapper.aspx if (await MyMessageBox.Show("my message", "my caption", "ok, got it", "that sucks") == MyMessageBoxResult.Button1) { // Do something Debug.WriteLine("OK"); } The class can be downloaded from the bottom of my older blog post. Comments about this post by Daniel Moth welcome at the original blog.

  • Masters or Second Bachelors Degree..or neither

    - by drD
    I have a degree in Business Administration, because at the time I didn't know what I wanted to do. I have been interested in programming for the past 2 years and have taken some action to self-teach. My experience/ knowledge base is limited to the following: -Read Kochan's Programming in C -Read IOS and Objective-C from the Big Nerd Ranch series -Obtained a C++ at NYU - thought it would be a good way to start to get a grasp on OO & design I would like to continue developing my skills, but most of all, re-orient how I am perceived as a professional. I am fully aware of how much a novice to this subject and would greatly appreciate any guidance anyone could give me. I currently have a job so full-time is not an option My goal is to become a software/ applications developer My questions are: -Should i take up a second bachelors in computer science? or a masters? or continue taking professional certificate programs (how are these viewed?) -If masters in computer science, would that make sense, if I dont have the formal foundation? (being a chief without ever being an Indian) -General advice for a novice to develop skill Thank You in advanced for helping me out.

  • Visual Studio 2010 Is Here!

    - by Bill Evjen
    I think back to the days of the first versions of Visual Studio (when it was called Visual Studio .NET, remember?) and I think about how far Microsoft has come with this IDE. It really is the best IDE on the market. There is so much to this IDE it is amazing. It now can really handle managing your complete software application development lifecycle. For me, it is (besides Windows 7) the best and most successful product Microsoft has developed. You can obviously get this now and it is available on MSDN and some other places: MSDN Visual Studio Trial Editions Visual Studio 2010 Express Editions (free) You will also find great info at the Visual Studio Developer Center. Some other interesting tidbits of info: JetBrain’s ReSharper 5.0 has been released for VS2010 Oracle will have the new Oracle Dev Tools for VS2010 within one month - http://bit.ly/9gC9NE Visual Studio 64-bit - Why there is no 64-bit version of VS - http://bit.ly/dhhwAj In installing this version of Visual Studio, if you have been working on the previous RC builds, then you are going to want to uninstall these previous editions of the 2010 product. You can do this through the Add Remove Programs dialog and you are going to want to select the appropriate item from the long list of Visual Studio items. You are then going to want to step through the Visual Studio dialog (it will seem as if you are installing it again) – and you will then come to a point where you can select the option to Uninstall the entire application. If you have installed the Silverlight 4 RC stuff, then you are also going to want to uninstall this and you are also going to want to uninstall the “Update for Visual Studio 2010 (KB976272)” before installing Silverlight RC2 – which you can find on www.silverlight.net.

  • I need a server or service that reroutes DNS requests

    - by Relentim
    We have two external servers, Dev and Prod. We are a software house and in the code we have a subdomain metrics.company.com that points to Prod. Development is continuous and our internal and external developers and testers will need to switch from Dev to Prod and back again. It is not an option to have a different sub domain in the code during development and change this for production. The way we wish to switch between Dev and Prod is to use DNS. We need a public DNS server that behaves normally apart from routing metrics.company.com to Dev. The users will be able to swap their DNS back and forward to hit the different servers. What is the easiest way to do this? Is there a company that hosts this service or am I going to have to rent a server and set it up myself? Any help would be much appreciated.

  • How to visualize the design of a program in order to communicate it to others

    - by Joris Meys
    I am (re-)designing some packages for R, and I am currently working out the necessary functions, objects, both internal and for the interface with the user. I have documented the individual functions and objects. So I have the description of all the little parts. Now I need to give an overview of how the parts fit together. The scheme of the motor so to say. I've started with making some flowchart-like graphs in Visio, but that quickly became a clumsy and useless collection of boxes, arrrows and-what-not. So hence the question: Is there specific software you can use for vizualizing the design of your program If so, care to share some tips on how to do this most efficiently If not, how do other designers create the scheme of their programs and communicate that to others? Edit: I am NOT asking how to explain complex processes to somebody, nor asking how to illustrate programming logic. I am asking how to communicate the design of a program/package, i.e.: the objects (with key features and representation if possible) the related functions (with arguments and function if possible) the interrelation between the functions at the interface and the internal functions (I'm talking about an extension package for a scripting language, keep that in mind) So something like this : But better. This is (part of) the interrelations between functions in the old package that I'm now redesigning for obvious reasons :-) PS : I made that graph myself, using code extraction tools on the source and feeding the interrelation matrix to yEd Graph Editor.
