  • Java Program Compilaton on Windows [closed]

    - by Mc Elroy
    I am trying to compile my program on the command line on windows using the java command and it says: Error: could not find or load main class or addition class It is for a program for adding two integers. I don't understand how to resolve the problem since I defined the static main class in my source code here is it: //Filename:addition.java //Usage: this program adds two numbers and displays their sum. //Author: Nyah Check, Developer @ Ink Corp.. //Licence: No warranty following the GNU Public licence import java.util.Scanner; //this imports the scanner class. public class addition { public static void main(String[] args) { Scanner input = new Scanner(System.in);//this creates scanners instance to take input from the input. int input1, input2, sum; System.out.printf("\nEnter First Integer: "); input1 = input.nextInt(); System.out.printf("\nEnter Second Integer: "); input2 = input.nextInt(); sum = input1 + input2; System.out.printf("\nThe Sum is: %d", sum); } }//This ends the class definition

  • Add custom command line to extended context menu in Windows 7

    - by 280Z28
    I have an application pinned to the task bar. 90% of the time, I run it with no additional command line options, so I can either click it (if not already open), or right click the icon and click the application name to open a new instance. I want to make it where when I right click it, there are 2 options listed: the first is the program with no command line options and the second is the one with a custom command line (that I hard code). If this is impossible, it would be tolerable to add it to the extended context menu (shift + right click the icon), but I prefer the former.

  • How do I block requests to Apache on a network interface?

    - by Dmitry Dulepov
    The problem: I have a local Apache instance on my Macbook Pro. I need it to listen on all network interfaces except en0 and en1 (basically, listen on lo and vnicX from Parallels). I know about "Listen *:80" but this is not a solution in this particular case. The only thing I could imagine if to use OS X firewall to block incoming requests to Apache on those interfaces. But I could not find any working examples and could not make such rules myself. Could somebody help, please?

  • Windows Load Balancing Services and File Shares

    - by cbkadel
    We are using Windows Load Balancing Services (WLBS). One of the things that I do notice, is that if I create a File Share on one of the physical hosts, I am able browse to that file share using the clustered-ip address. This might be a 'opinion' question, but I haven't been able to find much literature on file shares in particular with wlbs. Is this a recommendation configuration? Are there any limitations? What about when the share contains different sets of content on both hosts? For instance: Three 'hostnames' - host1 (physical1), host2 (physical2), and cluster. I create the following shares: \physical1\myshare \physical2\myshare What I notice is that i can see: \cluster\myshare I'm guessing that this is read-only, and that there's no file synchronization. But what happens if they are in fact out of sync, what would a network browser see then? Thanks for your time!

  • Block all third party domains from web pages

    - by wizlb
    When I'm browsing the web, I'd like to not be tracked by any third party services like Facebook or Google. For instance, if I visit somepage.com I don't want my browser requesting things from facebook.com unless I allow it. However, if I visit facebook.com, Facebook still works. Does anyone know of a Chrome or Firefox extension that will allow me to do this? AdBlock in Chrome doesn't seem to work because it just hides the web page elements, it doesn't stop the browser from downloading them. I imagine that some kind of proxy/browser extension hybrid would be the best. Any suggestions? Thank you.

  • Named my RPi 512MB @jerpi_bilbo

    - by hinkmond
    To keep our multiple Raspberry Pi boards apart from each other, I've now named my RPi Model B w/512MB: "jerpi_bilbo", which stands for Java Embedded Raspberry Pi - Bilbo (named after the Hobbit from the J.R.R. Tolkien stories). I also, set up a Twitter account for him. You can follow him at: @jerpi_bilbo He's self-tweeting, manual prompted so far (using Java Embedded 7.0 and twitter4j Java library). Works great! I'm setting him up to be automated self-tweeting soon, so watch for that... Here's a pointer to the open source twitter4j Java library: download here Just unzip and extract out the twitter4j-core-2.2.6.jar and put it on your Java Embedded classpath. Here's how @jerpi_bilbo uses it to Tweet with his Java Embedded runtime: import twitter4j.*; import java.io.* public final class Tweet { public static void main(String[] args) { String statusStr = null; if ((args.length 0) && (args[0] != null)) { statusStr = args[0]; } else { statusStr = new String("Hello World!"); } // Create new instance of the Twitter class Twitter twitter = new TwitterFactory().getInstance(); try { Status status = twitter.updateStatus(statusStr); System.out.println ("Successfully updated the status to: " + status.getText()); } catch (Exception e) { e.printStackTrace(); } } } That's all you need. Java Embedded rocks the RPi! And, @jerpi_bilbo is alive... Hinkmond

  • Amazon EC2 - Reserved Private Addresses

    - by reach4thelasers
    I've got a private DNS Server running on Amazon EC2. I don't need a public IP Address because its only used for private addressing web1.xxx.internal database1.xxx.internal Problem is I had to terminate the instance recently and start a new one. This meant that the private IP address of the DNS server changed and I had to log in to each of my other 15 server one-by-one and change the DNS address to point to the new DNS server. There must be a better way to do this, if so, what is it?

  • How to embed woff fonts for iframe source pages?

    - by Mon
    I am trying to make and embed a slideshow (of text, photo, audio, video, etc) in my site (HTML5) by loading webpages consecutively inside an iframe embedded in my first page. Most or all of the frame source pages, i.e. pages loaded inside first iframe are mine, but located in many different places. All of these pages are in an Indic language. Although I can use UTF-8 charset and lang="" declaration and that's probably enough functionally, but I also want to embed my preferred Indic unicode font in WOFF format via CSS3 @font-face rule , so the size and look of the text is uniform and the way I want it - throughout the slideshow. Problem is, there are many many pages in the slideshow all located in various places with many more linked pages, and it is next to impossible, or at least would be extremely tedious, to embed my custom WOFF font in every single page (which will also require separate css and uploading of fonts in every single instance). Besides, this may make the slideshow very heavy, sluggish and cumbersome for the user, since it will have to load the custom Indic font again and again everytime a new page is loaded in the iframe. I am not sure about this though. Is that how it works? I ask this, because I noticed that when I embedded my custom WOFF font in the 'first' page, it did not have any effect on the pages loaded inside the iframe. If I embed the font in some of the pages in the iframe, the next pages still don't get my font. Is there a way to embed my custom WOFF font only once, preferably in the first page where the first iframe is, and pass its effect on to all the pages embedded / loaded through the iframe and make their text show up as per my initially embedded woff font - without embedding my font in every single of them? Please help!

  • Logging in over ssh in a different session?

    - by Jordan Reiter
    I don't know exactly what the correct term is, but I notice if I log in to a remote SSH server, then close the window, open a new one, and log into that server again, my bash history and user processes appear to be different. For instance, if I started a background process I can't get back into it, or something I typed won't show up in my bash history. The problem is for some reason occasionally something happens to my remote session and instead of being disconnected the session just hangs; I have to close the window and open a new one to reconnect. As a result sometimes it means a long running process basically is "lost" since I can't get back into it. Is there any way to set it up so that when I log back in I log back in to the same "session"? This is using OS X Terminal.

  • How to change row color based on a single cell's value?

    - by flyfisher
    I have a spreadsheet where I have cell within a row that will contain specific text via data validation. So for instance a cell could contain the text "Due in 7 Days", "Past Due", or "Closed". I want the row color to change depending on the text that appears in the cell. So if the text "Past Due" appears in the cell I want that entire row to turn red, if "Due In 7 Days" appears the row should turn yellow, and if "Closed" the row would turn gray. How can I do that?

  • Network connection via USB

    - by Fco
    Can I get my Nexus One/Android on my local network over USB instead of WiFi and browse to my computer's IP address, the one to which the phone would be connected to, via USB? For instance, let's say my computer has an IP address 100.1.1.1 and when I go to it from the computer I would go to my localhost and see a website I've set up locally in the computer. Then, I connect my phone to that computer via USB. Can I then go to 100.1.1.1 from the browser and see the same website? All this through the USB, no WiFi?

  • SSL encryption standards by browser

    - by hfidgen
    Hiya, Does anyone have a table of the default levels of encryption which the various browsers out there support? For instance I know that IE5 and lower struggle even to cope with 40 bit encryption but the latest browsers easily do 256 and beyond. The reason I ask is that I'm looking to get a wildcard certificate for my domain and the price difference is huge between a server gated certificate (where it enforces a minimum of 128bit) and a non-gated certificate (where the browser sets the encryption level). Obviously I like the idea of paying £300 less for the non-gated certificate, but only if I can be sure that the majority of my users (FF3 / Opera / Chrome / IE7+) are going to get good encryption.

  • Ubuntu Wired network(ethernet does not work)

    - by user36777
    It was working just fine, until the other day I yanked it out. The wireless works just fine on the same router. If I login to a windows 7 instance on this dual boot laptop then the ehternet works just fine. So it's not a hardware, cable or router issue. The card even gets an ip, but I can't connect to the internet. Here are the details from route, iptables, ifconfig, ping etc. Any ideas? I have been struggling with this for day, none seems to have an answer. http://pastie.org/954816

  • Remote connection issue with Sql Server 2005 with SMS and Services but not IIS

    - by Mallioch
    Here is the situation: I have a Server 2008 box that is trying to connect to a Sql Server 2005 instance. Connections from websites running in the context of IIS work fine to the Sql Server machine using Sql Server authentication. Rockin'. However, using the same connection string, I cannot get a windows service on the same box to communicate with the Sql Server. Nor can I get management studio to connect from the same box. IIS great, other options no so much. For grins I have tried monkeying with the user accounts in the IIS app pools to match that of the service to get the sites to break and that hasn't worked, so it doesn't appear to be a user account issue. Since this is happening with two different programs and not with IIS, I'm assuming there is something shut down on the Sql Server that needs to allow non-IIS connecting things to communicate, but I have no idea what that would be. Any help would be appreciated.

  • How to enable a Web portal-based enterprise platform on different domains and hosts without customization

    - by S.Jalali
    I work at Coscend, a cloud and communications software product company. We have built a Web portal-based collaboration platform that we would like to host on five different Windows- and Linux-based servers in different hosting environments that run Web servers. Each of these Windows and Linux servers have a different host name and domain name (and IP address). Out team would appreciate your guidance on: (1) Is there a way to implement this Web portal-based platform on these Linux servers without customizing the host name, domain name and IP address for each individual instance? (2) Is there a way to create some variables using JavaScript for host name and domain name and call them from the different implementations? (3) Can these JavaScript modules be made portable and re-usable object modules for different environments and instances? The portal is written in JavaScript that is embedded in HTML5 and padded with CSS3. Other technologies include Flash, Flex. Databases used are PostgreSQL and MySQL.

  • Make middle-click close window(s) on unity launcher

    - by humanityANDpeace
    I am looking for a way to achieve this on my 12.04 ubuntu system: Clicking with the middle mouse button on one of the unity launcher icons will close the related windows/programs. At present a middle-button-click causes (when possible) another instance of the same programme to start. There is nothing wrong with that, only I use this less often than I need a quick way to close some programs. The current way is a lengthy 2-click way. Right-click on the icon Select "quit" in the unity-setting in the ccsm (compiz config settings manager) some few things can be changed in the ubuntu unity plugin already. there are other reporst about settings being done in dconf and gconf. What chances are there to tweak the behavior as described above? In Firefox I am used to close tabs by "middle-clicking" on the tabs. In GLX/Cairo-dock I also associate "middle-click" with the close the program. When using ubuntu unity launcher I keep on mistakingly opening new windows, when indeed I wanna close the respective window(s). :(

  • How can one one-handed ease working in Emacs?

    - by N.N.
    My right hand is temporarily immobilized. I would like to do some minor work in Emacs, mostly in Org-mode, but also some in AUCTeX. Is there some way to ease one-handed work in Emacs such as some mode or particular work flow? For instance I noticed pressing C-x u is easier than C-_ for undoing and that it is easier to mark text with methods involving C-Space than with combinations of S- and movement commands. I have found http://stackoverflow.com/questions/2391805/how-can-i-remain-productive-with-one-hand-completely-immobilized but that is not what I am asking for. I want to ease whatever little time spent one-handed in Emacs and this is also interesting for situations where there is no injury involved, such as when one hand is occupied. I also do realize I should avoid unnecessary strain.

  • FFMPEG Splitting MP4 with Same Quality

    - by Pragmatic
    I have one large MP4 file. I am attempting to split it into smaller files. ffmpeg -i largefile.mp4 -sameq -ss 00:00:00 -t 00:50:00 smallfile.mp4 I thought using -sameq would keep the same quality settings. However, I must not understand what that does. I'm looking to keep the same quality (audio/video) and compression with the split files. However, this setting makes the split files much larger. What flag(s) do I need to set to keep the same quality and attributes in the split files while maintaining the same quality to size ratio? For instance if my original file is about 12 GB and is 1920x1080 with a bitrate of 10617kbps and a framerate of 23 frames/sec and 6 channel audio with 317kbps, I would like the split files to be the same only a third of this size (if i split it into three pieces).

  • Run a script as root from apache

    - by Lord Loh.
    I would like to update my hosts file and restart dnsmasq from a web interface (php/apache2). I tried playing around with suid bits (the demonstaration). I have both apache and dnsmasq running on an EC2 instance. I understand that Linux ignores the setuid bit on text scripts, but works on binary files. (Have I got something wrong?). I added exec("whoami"); to the example C program in Wikipedia. Although the effective UID of the C program is 0, whoami does not return root :-( I would thoroughly like to avoid echo password | sudo service dnsmasq restart or adding apache to the sudoers without password! Is there a way out? How does webmin do such things?

It can connect fine to everythign else in the LAN, but cannot go out on the net It can be reached by ICMP requests over the net (the nagios server can probe it, but not ping it for instance), but not TCP Everything seems fine both in firewall and machine, i get no issues. Anyone care to help me out where i can start looking, i'm seriously confused. edit: it can ping gateway and through the sonicwall site to site VPN, it\s also able to resolve DNS. the only thing it can`t do is reach anything outside of LAN/VPN

  • Problems with 3D transformation - (SharpDX)

    - by Morphex
    First of all , I have been trying to get this right for a couple of day already, I have read so much info and still fail miserably to understand this. So I am going to tell you that even though I have done fairly amount of research myself, I failed to implement it. I must say miserably I am trying to create a generic camera class for a game engine of sorts - for research purposes only - the thing is I have no idea how to go about it. I have read about quaternions and matrices, but when it comes to the actual implementation I suck at it. Sharpdx has already Matrices and QUaternions implemented. SO no big deal on the map behind it. How in the world would I go about creating a camera? I have seen so many camera examples and still can't make one that works as expected. I would like to implement diferent types too (Orbital, 6DoF, FPS). So what is need for a camera? UP, Forward and Right vectors I read they are needed, also a quaternion for rotations, and View and Projection matrices. I understand that a FPS camera for instance only rotates around the World Y and the Right Axis of the camera. the 6DoF rotates always around their own axis, and the orbital is just translating for set distance and making it look always at a fixed target point. The concepts are there, now implementing this is not trivial for me. Can anyone point me on what am I missing, what I got wrong? I would really enjoy if you could give a tutorial, some piece of code, or just plain explanation of the concepts. Thank you for readin, a frustrated coder.

  • Access Domain over Wireless

    - by William
    I have an active directory server and all hard wired clients connect perfectly fine. However any wireless clients do not recognize that they are connected to the domain, despite the dns server being appropriately set to the domain controller for both wired and wireless connections. Also - both wired and wireless clients are on the same subnet. I am using a Verizon food actiontec router. What am I missing? For instance, this is the same computer connected first via an Ethernet cable and second via the wireless.

  • Observing MVC, can/should the Model be instantiated in the ViewController? Or where?

    - by user19410
    I'm writing an experimental iPhone app to learn about the MVC paradigm. I instantiate my Model class in the ViewController class. Is this stupid? I'm asking because storing the id of the Model class, and using it works where it's initialized, but referring to it later (in response to an interface action) crashes. Seemingly, the pointer address of my Model class instance changes, but how can that be? The code in question: @interface Soundcheck_Tone_GeneratorViewController : UIViewController { IBOutlet UIPickerView * frequencyWheel; @public Sinewave_Generation * sineGenerator; } @property(nonatomic,retain) Sinewave_Generation * sineGenerator; @end @implementation Soundcheck_Tone_GeneratorViewController @synthesize sineGenerator; - (void)viewDidLoad { [super viewDidLoad]; [self setSineGenerator:[[Sinewave_Generation alloc] initWithFrequency:20.0]]; // using reference -> fine } // pickerView handling is omitted here... - (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { [[self sineGenerator] setFrequency:20.0]; // using reference -> crash } @end // the Sinewave_Generation class... only to be thorough. Works fine so far. @interface Sinewave_Generation : NSObject { AudioComponentInstance toneUnit; @public double frequency,theta; } @property double frequency; - (Sinewave_Generation *) initWithFrequency: (int) f; @end @implementation Sinewave_Generation @synthesize frequency; - (Sinewave_Generation *) initWithFrequency: (int) f { self = [super init]; if ( self ) { [self setFrequency: f]; } return self; } @end

  • Manual vmware image creation

    - by Gzorg
    A laptop hard disk is being defective, but I managed to be lucky enough to get access to it, using an Ubuntu live cd. Now, I think it would be nice to dump the whole thing, using, for instance, a combination of gzip and split. But that would make the resulting files unusable. I could make a VMware image of it instead. I'm currently looking for the answer, which involves finding how vmware manages fixed size virtual partitions, but maybe you already did this before. Thanks.
