  • How to forward a [sub]domain to another address? (not just HTTP!)

    - by M. Joanis
    Hello everyone! I have bought domain1.me from GoDaddy... (yeah, I know... but ME domain registrars seemed quite hard to find...) I'm mainly hosted at 1and1. I have registered subdomain sub1.domain1.me and redirected it to my 1and1 account. That should eventually work fine. Then I have registered sub2.domain1.me and tried to redirect it to a box at home. It works #1 when for HTTP. I can access SSH server without any problem when I use the IP directly, but not when using sub2.domain1.me:22. The way I see this, they (GoDaddy) are redirecting only on port 80 (why would they?). I have looked at 1and1 forwarding too and they ask for an URI starting with http so I guess that's the same behavior. What are you guys doing to be able to host stuff from home (HTTP, SSH, SVN, Git, etc. etc.) using a domain name to prevent everyone to have to remember your IP??? Heeeelp! Thanks!

  • webmail suite recommendation

    - by hoball
    Hello, I have serveral emails in a few domains (email@domain1, email@domain2, email@domain3). Currently they are on an owned email server and I am collecting emails via IMAP protocol (i would not like to use POP..) in Thunderbird. I have a few partners and I want to allow them to access the same email address. Here is what I desired: All users can open All the inboxes via IMAP @ Thunderbird (with proper configuration) at the same time, there are a webmail system, every user can login their account (userA, userB, userC), and they will see all inboxes (email@domain1, email@domain2, email@domain3) Would you recommend any suite that fits my needs? Either (a system to be installed on my server) or (a remote service where I need to config MX records) will do. Thank you.

  • How can i update Preview.app from the command line without loosing focus on OSX ?

    - by snies
    Hello, i want to update Preview.app in the background from the command line without loosing focus of my current window. I know that i can use the following to open/update the view of a file, but than i loose focus to the Preview.app. open -a Preview foo.pdf I guess there might be some clever Apple Script commands to do so but so far i didn't find the right one. Alternatively i would be interested into transfering the focus back to my current app directly after the update. I need this in order to update Preview.app's view of a pdf through a vi autocmd after i update the pdf according to changes in a tex file i am editing. Here is an example of what i want to achive but using Ubuntu and evince.

  • environment variable issue in shell

    - by George2
    I am using Red Hat Linux Enterprise 5. I know the theory that -- using export to set environment variable, the environment variable will apply to current and child environment, but without using export to set environment variable, the environment variable will only apply to the current environment. My confusion is, what is the exact definition of "child environment" and "current environment"? For example, $ var1=123 $ echo "Hello [$var1]" the value of var1 (which is 123) is printed in shell, but I think echo is a command invoked by current shell, and it (the echo command) should be a child environment of current shell and the value of var1 should not (because not using export var1=123) impact echo. Any comments? Thanks in advance!

  • WebLogic Server 11gR1 Interactive Quick Reference

    - by JuergenKress
    The WebLogic Server 11gR1 Administration interactive quick reference is a multimedia tool for various terms and concepts used in WebLogic Server architecture. This tool is available for administrators for online or offline use. This is built as a multimedia web page which provides descriptions of WebLogic Server Architectural components, and references to relevant documentation. This tool offers valuable reference information for any complex concept or product in an intuitive and useful manner. Each interactive type presents data that may be available in the documentation (in the case of Oracle products), but presents it in a way that is more intuitive and useful to a user of Oracle products because it displays data the way it is used in a real world, best practice scenario. For example, the architectural diagram interactive type provides an image of an architectural diagram that is typically larger than a single slide or paper. The image is scrollable and provides zoom capabilities to easily and clearly view any part of the image. The image itself contains a hotspot map that you can click to get more information about a feature, including reference links to the documentation in question. Linking the visual image of the component and where it fits in the overall architecture of the product, or technology in use, to the technical explanation and how-to materials related to that component is something not offered by the documentation. In a future release, the poster will also enable you to drill down even further into the individual subsystems in nested diagrams to look at the details of that subsystem. In short, the interactive posters are good at showing you the big picture, then quickly and easily getting you to the detailed information you need. In an instant, you can see where a technical component fits into an overall architecture, and zero in on the nitty-gritty details that show you how to do it yourself. Note: This is a first initial release with more features in development. Currently known information: Only Firefox 8.0 and higher is known to work with this product. This product may work with Chrome and Safari browsers, but is known to have issues in Internet Explorer at this time. Smartphones, such as iPads and iPhones, are partially supported WebLogic Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

  • Help with Apache rewriteengine rules

    - by Vinay
    Hello - I am trying to write a simple rewrite rule using the rewriteengine in apache. I want to redirect all traffic destined to a website unless the traffic originates from a specific IP address and the URI contains two specific strings. RewriteEngine On RewriteLog /var/log/apache2/rewrite_kudithipudi.log RewriteLogLevel 1 RewriteCond %{REMOTE_ADDR} ^199\.27\.130\.105 RewriteCond %{REQUEST_URI} !/StringOne [NC, OR] RewriteCond %{REQUEST_URI} !/StringTwo [NC] RewriteRule ^/(.*) http://www.google.com [R=302,L] I put these statements in my virtual host configuration. But the rewriteengine seems to be redirect all requests, whether they match the condition or not. Am I missing something? Thank you. Vinay.

  • Apache availability with the two front-ends on diferent locations. Is it possible?

    - by marc.riera
    Hello, I have to locations (office and service providers). One DNS(bind) serving our domain as authoritative, and a service provider webserver with our corporate web on a private server. So.. Now we are planing to upgrade our server on the ISP to a new one, and I would like to use this situation to improve our service. Is it possible to mount a high availability apache/mysql/php within to different locations? I will install a bind slave on the same new server, so I hope it will make things easier, but I need some hints and tips on how to ride it. THanks.

  • Tunneling HTTP traffic from a particular host/port

    - by knoopx
    Hello, I'm trying to figure out how to access from my development machine (Devel) to a third party web service (www.domain.com) which I am not allowed to directly contact using my office IP address. Here's a basic diagram (i'm not allowed to post images...): http://yuml.me/diagram/scruffy/class/%5BDevel%5D-%5BA%5D,%20%5BA%5D-%5BB%5D,%20%5BB%5D-%5Bwww.domain.com%5D The only machine allowed to access that service is B (production server) but I do neither can directly access it from my development machine (Devel). So in order to access the web service I have to ssh into A, and then from A to B to access www.domain.com Is there any way of tunneling traffic from B to A and then back to my development machine so I can directly access www.domain.com without having to ssh into every box? Devel: My development machine. A, B: Linux servers. I own root access on both. B: Production server www.domain.com: Third party HTTP API production server uses.

  • DNS protocol message example

    - by virtual-lab
    hello there, I am trying to figure out how to send out DNS messages from an application socket adapter to a DNSBL. I spent the last two days understanding the basics, including experimenting with WireShark to catch an example of message exchanged. Now I would like to query the DNS without using dig or host command (I'm using Ubuntu); how can I perform this action at low level, without the help of these tools in wrapping the request in a proper DNS message format? How the message should be post it? Hex or String? Thanks in advance for any help. Regards Alessandro Ilardo

  • vim: how do I keep 10 lines visible when scrolling up to EOF with CRTL-F ???

    - by Gaston
    Hello! I am used to use vi, not vim. What I find annoying in vim is that when you are scrolling with CTRL-F and reach EOF, vim scrolls down to the very last line and put this line on the top of your screen, and you can't see the lines above. You must scroll up a little bit so you can see the context. All this happens with CTRL-F only, not with j or the down cursor key. In vi, you scroll down (with CTRL-F), but when you reach EOF it still show you, say, 15 lines and then the tippical ~. I am using Putty for remote access. How can I config vim to behave like vi in this case? Hope you understand the question. Thank you! Gaston.

  • How to convert a mpeg4-aac video to mpeg-ts using MEncoder?

    - by Mahendra Liya
    Hello, I know this can be done using FFMpeg and I have done it. The only problem here was that FFMpeg actually tries to "encode" the file while converting to mpeg-ts which I don't want. i.e. I just want to change the container format to mpeg-ts without encoding the media. Is this type of conversion possible with FFMpeg? (I know about "copy" option, but it works with H264-aac and not with mpeg4-aac). Is it possible to change mpeg4-aac to mpeg-ts container format with MEncoder? I wish to know the personal opinion/advice of those who have already worked on such stuff. Thanks in advance.

  • Java Applet Tower Defence Game needs tweeking

    - by Ephiras
    Hello :) i have made a tower defence Game for my computer science class as one of my major projects, but have encountered some rather fatal roadblocks. here they are creating a menu screen (class Menu) that can set the total number of enimies, the max number of towers, starting money and the map. i tried creating a constructor in my Main class that sets all the values to whatever the Menu class passes in. I want the Menu screen to close after a difficulty has been selected and the main class to begin. Another problem i would really like some help with is instead of having to write entire arrays i would like to create a small segment of code that runs through an entire picture and sets up an array based on that pixels color.this way i can have multiple levels just dragged into a level folder and have the program read through them. users can even create their own. so a 1 if its yellow, a two if blue and a 3 if purple, then everything else = 0; you can download all the classes and code uif you'd like here sorry about having to redirect you but i wasn't sure how to efficently add a code spoiler. help is greatly appreciated

  • Playing with F#

    - by mroberts
    Project Euler is a awesome site.   When working with a new language it can be tricky to find problems that need solving, that are more complex than "Hello World" and simpler than a full blown application. Project Euler gives use just that, cool and thought provoking problems that usually don't take days to solve.  I've solved a number of questions with C# and some with Java.  BTW, I used Java because it had BigInteger support before .Net. A couple weeks ago, back when winter had a firm grip on Columbus, OH, I began playing (researching) with F#.  I began with Problem #1 from Project Euler.  I started by looking at my solution in C#. Here is my solution in C#. 1: using System; 2: using System.Collections.Generic; 3:   4: namespace Problem001 5: { 6: class Program 7: { 8: static void Main(string[] args) 9: { 10: List<int> values = new List<int>(); 11:   12: for (int i = 1; i < 1000; i++) 13: { 14: if (i % 3 == 0 || i % 5 == 0) 15: values.Add(i); 16: } 17: int total = 0; 18:   19: values.ForEach(v => total += v); 20:   21: Console.WriteLine(total); 22: Console.ReadKey(); 23: } 24: } 25: }   Now, after much tweaking and learning, here is my solution in F#.   1: open System 2:   3: let calc n = 4: [1..n] 5: |> List.map (fun x -> if (x % 3 = 0 || x % 5 = 0) then x else 0) 6: |> List.sum 7:   8: let main() = 9: calc 999 10: |> printfn "result = %d" 11: Console.ReadKey(true) |> ignore 12:   13: main() Just this little example highlights some cool things about F#. Type inference. F# infers the type of a value.  In the C# code above we declare a number of variables, the list, and a couple ints.  F# does not require this, it infers the calc (a function) accepts a int and returns a int. Great built in functionality for Lists.  List.map for example. BTW, I don’t think I’m spilling the beans by giving away the code for Problem 1.  It by far is the easiest question, IMHO, solved by 92,000+ people. Next I’ll look into writing a class library with F#.

  • Windows8, JavaScript and HTML5 - A good thing?

    - by Albers
    Most of us have seen the Windows 8 news regarding support for native HTML5/JavaScript applications. The press has pushed this as a potential threat to the .NET developer community because JavaScript and HTML5 were called "our new developer platform". The press release refers to "Web-connected and Web-powered apps built using HTML5 and JavaScript that have access to the full power of the PC.".Microsoft has also been hush on details related to these comments. Before we buy the hype and start worrying about a world where we drop our Visual Studio licenses and buy DreamWeaver - let's think about how Windows 8 HTML/JavaScript applications would be implemented. The HTML5 spec offers support for offline applications, but this won't offer the OS-integrated experience the press release refers to. MS has to be planning a way to extend access beyond the traditional JavaScript feature set. Microsoft has a similar option today: HTML Applications or HTAs. They come close to required features, but HTAs need ActiveX or Java integration to provide the promised OS-level access. I'm guessing that Microsoft's future OS strategy isn't built on developers cranking out ActiveX controls or Java applets. So where is Microsoft headed? One possibility is that MS builds a new JavaScript framework from the ground up outside their current APIs. Another idea would be for Microsoft to add support for JavaScript as a first class .NET language using the Dynamic Language Runtime. A solution based on the DLR could be integrated into an HTA-like model to provide the promised access, along with the full range of features in .NET Framework. Security comes included in the Framework. And the work necessary to support this integration would tie in nicely with the effort MS has recently made providing better JavaScript and HTML5 support in Visual Studio 2010. As a bonus, a full-fledged JavaScript DLR implementation would allow single language web solutions across client and server (think node.js) and would appeal to developers who are familiar with JavaScript but have less experience with the Microsoft tech stack. We will all get a better picture after the Build conference in September. But in the mean time we know that Microsoft has a reputation for providing strong developer support. We might want to reserve our harshest judgement and consider that the press release could hint at new opportunities for .NET development.

  • Servicing a WIM image with the recently released SP1 for Windows 7/Server 2008 R2

    - by noonand
    Hello, I normally hang out over on SO but wanted to ask this question in a more appropriate forum. I have, for the sheer fun of learning how to do (as I'm sick of GHOST and dd images) set up WDS and captured a reference WIM file. One of the things that I remember being promised was the ability to do offline servicing of WIM files. I'm just wondering what the actual procedure is for this? I have the full SP1 ISO down (covers 7 and 2008R2) and was wondering about next steps. If someone could point me in the right direction I'd appreciate it greatly. Thanks - Derek

  • How to make an ISO copy of Linux-filesystem and user files of VPS Debian based?

    - by moogeek
    Hello! I have a Debian-Based VPS on some hosting. I want to migrate from it and i need to make a full copy of all Linux-filesystem (and installed packages) + all home directory with website files. And then pack/convert it to ISO image so that to use it on cloud hostings like Amazon. The problem is that i have only ssh root access. Hosting support can't do that for me. Another part of the question - is it possible to enlarge the Linux-filesystem by not re-installing it and using the free space of home directory? Is it possible to do? I guess it is possible with rsync or something like that. Will my Mysql databes copy together with all other data? Thanks in advance!

  • SFX Played Once per Collision or Hit

    - by David Dimalanta
    I have a question about using Box2D (engine for LibGDX used to make realistic physics). I observed on the code that I've made for the physics here below: @Override public boolean touchUp(int screenX, int screenY, int pointer, int button) { // TODO Touch Up Event if(is_Next_Fruit_Touched) { BodyEditorLoader Fruit_Loader = new BodyEditorLoader(Gdx.files.internal("Shape_Physics/Fruity Physics.json")); Fruit_BD.type = BodyType.DynamicBody; Fruit_BD.position.set(x, y); FixtureDef Fruit_FD = new FixtureDef(); // --> Allows you to make the object's physics. Fruit_FD.density = 1.0f; Fruit_FD.friction = 0.7f; Fruit_FD.restitution = 0.2f; MassData mass = new MassData(); mass.mass = 5f; Fruit_Body[n] = world.createBody(Fruit_BD); Fruit_Body[n].setActive(true); // --> Let your dragon fall. Fruit_Body[n].setMassData(mass); Fruit_Body[n].setGravityScale(1.0f); System.out.println("Eggs... " + n); Fruit_Loader.attachFixture(Fruit_Body[n], Body, Fruit_FD, Fruit_IMG.getWidth()); Fruit_Origin = Fruit_Loader.getOrigin(Body, Fruit_IMG.getWidth()).cpy(); is_Next_Fruit_Touched = false; up = y; Gdx.app.log("Initial Y-coordinate", "Y at " + up); //Once it's touched, the next fruit will set to drag. if(n < 50) { n++; }else{ System.exit(0); } } return true; } Now, I'm thinking which part o line should I implement for the sound effects. My objectives to make SFX played once for every collision (Or should I say "SFX played once per collision"?) on the following: SFX played once if they hit on the objects of its kind. (e.g. apple vs. apple) SFX played once on a different sound when it hit on the ground. (e.g. apple land on the mud) Take note that I'm using Box2D for the Java programming version thanks to LibGDX via Box2D engine and I edited the physics body using Physics Body Editor before I implement it to code. I tried to check every available methods for body, fixture definition, or body definition to code for the SFX when hit but it seems only for the gravity and weight. Is there possibly available on the document for SFX played when collision happens if possible?

  • netcat as a multithread server

    - by etuardu
    Hello, I use netcat to run a simple server like this: while true; do nc -l -p 2468 -e ./my_exe; done This way, anyone is able to connect to my host on port 2468 and talk with "my_exe". Unfortunately, if someone else wants to connect during an open session, it would get a "Connection refused" error, because netcat is no longer in listening until the next "while" loop. Is there a way to make netcat behave like a multithread server, i.e. always in listening for incoming connections? If not, are there some workarounds for this? Thank you all!

  • Any ideas about how to make Programming Techniques Class more interesting.

    - by Eedoh
    Hello. I already found similar question here on SO, but almost all the answers were more philosophical, then practical. I'd like You to share some of Your PRACTICAL ideas about how to make my course more interesting. It doesn't matter how much effort it takes from me. I even thought about trying to motivate them to pick some topic in the beginning of the course and to work on it as some kind of real, small, startup project that they could maybe financially exploit once it's finished. But I'm afraid that most of them will not get the project to the end, and that it could be boring to them working on one thing all year long. Also I thought about involving them in Torcs, but I'm afraid most of them wouldn't be up to the task. Btw, Torcs is Car Racing Simulation, but there's an API for developers so they can develop their own AI for the driver, and then race their cars against the other programmer's AI's. I'm not asking here for problem examples, as I asked a separate question about that. I need ideas about making my lectures more interesting and fun.
