  • Is there a faster way to download a page from the net to a string?

    - by cphil5
    I have tried other methods to download info from a URL, but needed a faster one. I need to download and parse about 250 separate pages, and would like the app to not appear ridiculously slow. This is the code I am currently using to retrieve a single page, any insight would be great. try { URL myURL = new URL("http://www.google.com"); URLConnection ucon = myURL.openConnection(); InputStream inputStream = ucon.getInputStream(); BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream); ByteArrayBuffer byteArrayBuffer = new ByteArrayBuffer(50); int current = 0; while ((current = bufferedInputStream.read()) != -1) { byteArrayBuffer.append((byte) current); } tempString = new String(byteArrayBuffer.toByteArray()); } catch (Exception e) { Log.i("Error",e.toString()); }

    Hi. I've just made the switch to Ubuntu on my main PC and I've been looking for a media player that can: Play all the usual video formats Rate (and ideally, tag) each file Display thumbnails for each file Other than that there isn't much I'm after. Banshee comes close, but doesn't display thumbnails. I've Google'd lots but I'm running out of search terms to try. Does anyone have any suggestions? Cheers!

  • Which version of emacs is best on Mac?

    - by justinhj
    On windows and ubuntu I just download the latest drops of emacs straight from the gun/fsf site, but they don't have Mac binaries there. I have a decent version that came with Snow Leopard, but just running in the bash terminal. Is there a version that runs in a standalone window and is more Mac friendly? I did try using ports, and downloaded one called emacs cocoa, but it didn't compile.

  • Prepared statement initialized tiwice and closed once

    - by sonam
    Hi, I want to know that if a PreparedStatement object is initialized twice the way shown in code snippet below and closed only once in finally block, will it fail to close? I am not getting any error in this code but will it be a better idea to use 2 different preparedStatements instead of one. I think it fails to close the preparedStatement at #1. Connection conn = null; PreparedStatement ps = null; try { conn = getConnection(); ps = conn.prepareStatement(QueryUtil.UPDATE_POLICY_DETAILS); // #1 ps.setInt(1, iCancellationPolicyId); ps.executeUpdate(); //some code here ps = conn.prepareStatement(QueryUtil.UPDATE_POLICY_CHARGES); // #2 ps.setInt(1, iCancellationPolicyId); ps.executeUpdate(); //some code here } catch (SQLException sqlExp) { sqlExp.printStackTrace(); LOG.fatal(sqlExp); } finally { conn.close(); ps.close(); }

  • Handling download abort in PHP

    - by Aron Rotteveel
    Is it somehow possible to handle a download abort in PHP? In this specific case I am not speaking of a connection abort, but handling the event that triggers when the 'cancel' button in the browser download dialog button is clicked. Since this dialog already interprets the headers of the file that is to be download but does not actually start the download, it only seems logical there should be some way to catch this. Small (pseudo) code example to clear things up: // set some headers header('...'); // Question: what happens between the part where the headers are sent // and the actual data is being outputted to the client? IE: this is the part // where the download dialog should show up // Logical question that follows is: is there a way to detect a 'cancel'? $filename = '/some/file.txt'; $handle = fopen($filename, 'rb'); // output data to client while (!feof($handle)) { echo fread($handle, 8096); } fclose($handle);

  • How to force main Acivity to wait for subactivity in Android?

    - by rmaster
    hi, I am calling a subactivity from main activity. This subactivity should take few numbers from user (i'm using Edit text control to achieve this), save them to static variable in another class and terminate. I want main activity to wait for subactivity but both are just running simultaneously. Even doing sth like that doesn't help: Thread t = new Thread(new Runnable(){ public void run(){ Log.v("==================", "run "+new Date()); startActivityForResult(new Intent(ctx,myCustomSubactivity.class),1); } }); Log.v("==================", "calling run "+new Date()); t.start(); try { t.join(); } catch (InterruptedException e) {Log.v("==================", "can't join");} Log.v("==================", "back from activity "+new Date()); do you know how to force main activity to wait? Thread.wait() method is not supported in Android(program throws error).

  • tmux equivalent of "screen -R"?

    - by Drew Frank
    The tmux attach command acts more like a combination of screen -r and screen -x -- first it trys to attach to the most recently detached session, and then if none is available it will attach to a currently attached session. I want to emulate the behavior of screen -R: first try to attach to a detached session, then start a new session if there were no detached sessions. What is the best way to achieve this in tmux?

  • Ruby Methods: return an usage string when insufficient arguments are given

    - by Shyam
    Hi, After creating a serious bunch of classes, with initialize methods, loading them in IRb requires to look back at the code. However, I think it should be easy enough to return a usage message, instead of: ArgumentError: wrong number of arguments (0 for 9) So I prefer to return a string with the human readable arguments, by example using "puts" or just a return of a string. Now I have seen the rescue keyword inside begin-end code, but I wonder how I could catch the ArgumentError when the initialize method is called. Thank you for your answers, feedback and comments!

  • Request/Response pattern in SOA implementation

    - by UserControl
    In some enterprise-like project (.NET, WCF) i saw that all service contracts accept a single Request parameter and always return Response: [DataContract] public class CustomerRequest : RequestBase { [DataMember] public long Id { get; set; } } [DataContract] public class CustomerResponse : ResponseBase { [DataMember] public CustomerInfo Customer { get; set; } } where RequestBase/ResponseBase contain common stuff like ErrorCode, Context, etc. Bodies of both service methods and proxies are wrapped in try/catch, so the only way to check for errors is looking at ResponseBase.ErrorCode (which is enumeration). I want to know how this technique is called and why it's better compared to passing what's needed as method parameters and using standard WCF context passing/faults mechanisms?

  • Practical way to implement prevention of IP Spoofing

    - by user1369975
    I am an undergraduate Computer Science student and was hoping to gain some knowledge of ways to help prevent IP spoofing but all the resources I have tried out elaborate this concept in a theoretical way. I want to try out my hands at one of the techniques like: http://en.wikipedia.org/wiki/Port_knocking http://en.wikipedia.org/wiki/SYN_cookies How do I simulate this whole situation in my own system were I myself am the attacker and I myself have to defend it? And once I have gained an understanding of it, then how do I start translating that into programming terms?

  • cygwin running commands with switches when ssh in

    - by Troz123
    When I SSH into a Windows 2008 R2 box and try to run a command with switches like /cygdrive/c/directory/Reports.exe /ReportID=1 /DateRange=LastWeek the command just hangs and never finishes. I can see the Reports.exe spawn a process under the user but never finishes. If I RDP into the box open cygwin terminal and run the exact command it works. Any reason why I can't run the command when I SSH in?

  • Is my external hard drive dying?

    - by thatotherguy
    I keep getting this error lately when I try to copy large (200+ MB) files over to my external. Following this, the disk becomes unresponsive and I got to unplug it and plug it in again to work. The copy process also is unreasonably slow. It is worth noting that this happens on Windows too, so it's not the notorious "Error -36" bug OS X had prior to 10.6.3. The disk is a Western Digital 3200BMV. Any ideas?

  • Where to add an observer to the NotificationCenter in a UITableViewController

    - by Saifis
    I want to send a notification from a UITableViewController-A to UITableViewController-B. I was adding the observer in the initwithCoder of the UITableViewController that is supposed to catch the notifications. The classes are correlated as folows RootViewController ===NavigationController-A =====UITableViewController-A ===NavigationController-B =====UITableViewController-B I need to add the observer before the views are actually loaded because notifications may be sent before the view is called. However I have been told that initializing in the initWithCoder method in a UIViewController is not advisable, and was told to add the observer in the AppDelegate. Are there any other suggestions for doing this?

  • Ubuntu Server on live Internet

    - by vaibhav
    I just installed Ubuntu Server 12.04 in an office machine with openSSH, DNS and LAMP Server. I also made the IP static and I can access the server in my office premises easily, but when I try to access my server from my home it is not working. I know I have to make some changes and need to install some firewall (I had just gone through with a couple of posts) but I guess an expert advise will save my time here.

  • Python cannot go over internet network

    - by user1642826
    I am currently trying to work with python networking and I have reached a bit of a road block. I am not able to network with any computer but localhost, which is kind-of useless with what networking is concerned. I have tried on my local network, from one computer to another, and I have tried over the internet, both fail. The only time I can make it work is if (when running on the server's computer) it's ip is set as 'localhost' or '192.168.2.129' (computers ip). I have spent hours going over opening ports with my isp and have gotten nowhere, so I decided to try this forum. I have my windows firewall down and I have included some pictures of important screen shots. I have no idea what the problem is and this has spanned almost a year of calls to my isp. The computer, modem, and router have all been replaced in that time. Screen shots: import socket import threading import socketserver class ThreadedTCPRequestHandler(socketserver.BaseRequestHandler): def handle(self): data = self.request.recv(1024) cur_thread = threading.current_thread() response = "{}: {}".format(cur_thread.name, data) self.request.sendall(b'worked') class ThreadedTCPServer(socketserver.ThreadingMixIn, socketserver.TCPServer): pass def client(ip, port, message): sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.connect((ip, port)) try: sock.sendall(message) response = sock.recv(1024) print("Received: {}".format(response)) finally: sock.close() if __name__ == "__main__": # Port 0 means to select an arbitrary unused port HOST, PORT = "192.168.2.129", 9000 server = ThreadedTCPServer((HOST, PORT), ThreadedTCPRequestHandler) ip, port = server.server_address # Start a thread with the server -- that thread will then start one # more thread for each request server_thread = threading.Thread(target=server.serve_forever) # Exit the server thread when the main thread terminates server_thread.daemon = True server_thread.start() print("Server loop running in thread:", server_thread.name) ip = '12.34.56.789' print(ip, port) client(ip, port, b'Hello World 1') client(ip, port, b'Hello World 2') client(ip, port, b'Hello World 3') server.shutdown() I do not know where the error is occurring. I get this error: Traceback (most recent call last): File "C:\Users\Dr.Frev\Desktop\serverTest.py", line 43, in <module> client(ip, port, b'Hello World 1') File "C:\Users\Dr.Frev\Desktop\serverTest.py", line 18, in client sock.connect((ip, port)) socket.error: [Errno 10061] No connection could be made because the target machine actively refused it Any help will be greatly appreciated. *if this isn't a proper forum for this, could someone direct me to a more appropriate one.

  • Need help on how to setup my packages and projects in eclipse

    - by jax
    I am new to Java and am making a license generator. This is my current setup. com.example.licensegenerator.client (used by the client application) :LicenseLoader (no Main method) :LicenseDownloader (no Main method) com.example.licensegenerator.server.keys (used by the server) :ProductKeyGenerator(Main method) com.example.licensegenerator.server.license (used on the server also) :LicenseGenerator(Main method) com.example.licensegenerator.lib (Shared classes between client and server) :Contants (no main) Now I have a few questions. Is it OK to have multiple Main() methods in a single project? Will I be able to compile them to different .jar files? (In this case I need two different jars for the server) Is there a better way to setup the packages? And a totally unrelated question, with exceptions, is it better to handle them right then and there or throw them and let the main method catch them all (the program cannot recover if an error occurs)
