  • Java - How to detect that the internet connection has got disconnected through a java desktop applic

    - by Yatendra Goel
    I am developing a Java Desktop Application that access internet. It is a multi-threaded application, each thread do the same work (means each thread is an instance of same Thread class). Now, as all the threads need internet connection to be active, there should be some mechanism that detects whether an internet connection is active or not. Q1. How to detect whether the internet connection is active or not? Q2. Where to implement this internet-status-check-mechanism code? Should I start a separate thread for checking internet status regularly and notifies all the threads when the status changes from one state to another? Or should I let each thread check for the internet-status itself? Q3. This issue should be a very common issue as every application accessing an internet should deal with this problem. So how other developers usually deal with this problem? Q4. If you could give me a reference to a good demo application that addresses this issue then it would greatly help me.

  • Building a Data Warehouse

    - by Paul
    I've seen tutorials articles and posts on how to build datawarehouses with star and snowflakes schemas, denormalization of OLTP databases fact and dimension tables and so on. Also seen comments like: Star schemas are for datamarts, at best. There is absolutely no way a true enterprise data warehouse could be represented in a star schema, or snowflake either. I want to create a database that will server for reporting services and maybe (if that isn't enough) install analisys services and extract reports and data from cubes. My question was : Is it really necesarry to redesign my current database and follow the star/snowflake schemas with fact and dimension tables ? Thank you

  • MSTest unit test passes by itself, fails when other tests are run

    - by Sarah Vessels
    I'm having trouble with some MSTest unit tests that pass when I run them individually but fail when I run the entire unit test class. The tests test some code that SLaks helped me with earlier, and he warned me what I was doing wasn't thread-safe. However, now my code is more complicated and I don't know how to go about making it thread-safe. Here's what I have: public static class DLLConfig { private static string _domain; public static string Domain { get { return _domain = AlwaysReadFromFile ? readCredentialFromFile(DOMAIN_TAG) : _domain ?? readCredentialFromFile(DOMAIN_TAG); } } } And my test is simple: string expected = "the value I know exists in the file"; string actual = DLLConfig.Domain; Assert.AreEqual(expected, actual); When I run this test by itself, it passes. When I run it alongside all the other tests in the test class (which perform similar checks on different properties), actual is null and the test fails. I note this is not a problem with a property whose type is a custom Enum type; maybe I'm having this problem with the Domain property because it is a string? Or maybe it's a multi-threaded issue with how MSTest works?

  • What equipment do real ISP's use?

    - by Allanrbo
    In a dormitory of 550 residents, people often mistakenly set up DHCP servers for the whole network by plugging in their private Wi-Fi routers wrongly. Also recently, someone mistakenly configured their PC to a static IP being the same as that of the default gateway. We use cheap 3Com switches at the moment. I know that Cisco switches support DHCP snooping to solve the DHCP problem, but that still does not solve the default gateway IP takeover problem. What sort of switch equipment do real ISP's use so their customers cannot break the network for the other customers? What we ended up doing In case anyone are courious, we ended up doing seperate VLANs for each user. And as a matter of fact, not just the 550 users, but for 2500 users (11 dorms). Here's a page describing the setup: http://k-net.dk/technicalsetup/ (the section "Transparent firewall using VLANs"). There was no significant load on the router server as I feared in one of the comments below. Even at 800Mpbs.

  • Debian date jumping, causing complete lockup

    - by artfulrobot
    I have a Debian Squeeze VM that has suddenly chosen to jump it's date forwards just over a month, which seems to confuse it no end and cause it to require a hard reset (yikes!). There is nothing unusual in the logs, except that the datestamp suddenly jumps (today back to 2005). It's happened three times, so I don't think it's to do with the leap second issue as the last one of those was in July. When it happened once I spent ages checking stuff but could not find anything, decided to forget it. But three times is becoming an issue on a production server. Edits providing information requested in comments (thanks!): I do not have control over the hypervisor, it is a hired VM. # cat /sys/devices/system/clocksource/clocksource0/current_clocksource kvm-clock # ntpq -p remote refid st t when poll reach delay offset jitter ============================================================================== +grendel.exizten 130.149.17.8 2 u 29 64 77 14.811 1.778 1.744 *panoramix.linoc 193.67.79.202 2 u 32 64 77 19.729 -0.419 1.691 +robert.elnounch 213.251.128.249 2 u 27 64 77 17.762 0.600 1.722 -janetzki.eu 83.169.43.165 3 u 31 64 77 27.214 3.575 1.638

  • Why does waking a PC up with a timer act differently than with the power button?

    - by Dan Rasmussen
    I have a Windows 7 machine set up as a server. It has no monitor and is only accessed through remote desktop. I set up two scheduled tasks, one to put the computer to sleep at night and another to wake it up in the morning. When it's woken up from sleep via a timer, it stays awake for only a couple minutes before going back to sleep. When woken up by pushing the power button, however, it stays awake all the way until the sleep timer. Why does my PC behave differently in these two scenarios? I have set the PC not to prompt for a user's password on wake, since I worried that the login screen might follow different power rules. I tried SmartPower Configuration but had the same problems. I can provide more details if questions are asked in the comments, but I'm not sure what's relevant.

  • php-fpm start error

  • Ruby on Rails is complaining about a method that doesn't exist that is built into Active Record. Wha

    - by grg-n-sox
    This will probably just be a simple problem and I am just blind or an idiot but I could use some help. So I am going over some basic guides in Rails, reviewing the basics and such for an upcoming exam. One of the guides included was the sort-of-standard getting started guide over at guide.rubyonrails.org. Here is the link if you need it. Also all my code is for my app is from there, so I have no problem releasing any of my code since it should be the same as shown there. I didn't do a copy paste, but I basically was typing with Vim in one half of my screen and the web page in the other half, typing what I see. http://guides.rubyonrails.org/getting_started.html So like I said, I am going along the guide when I noticed past a certain point in the tutorial, I was always getting an error on the site. To find the section of code, just hit Ctrl+f on the page (or whatever you have search/find set to) and enter "accepts_". This should immediately direct you to this chunk of code. class Post < ActiveRecord::Base validates_presence_of :name, :title validates_length_of :title, :minimum => 5 has_many :comments has_many :tags accepts_nested_attributes_for :tags, :allow_destroy => :true , :reject_if => proc { |attrs| attrs.all? { |k, v| v.blank? } } end So I tried putting this in my code. It is in ~/Rails/blog/app/models/post.rb in case you are wondering. However, even after all the other code I put in past that in the guide, hoping I was just missing some line of code that would come up later in the guide. But nothing, same error every time. This is what I get. NoMethodError in PostsController#index undefined method `accepts_nested_attributes_for' for #<Class:0xb7109f98> /usr/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/active_record/base.rb:1833:in `method_missing' app/models/post.rb:7 app/controllers/posts_controller.rb:9:in `index' Request Parameters: None Response Headers: {"Content-Type"=>"", "cookie"=>[], "Cache-Control"=>"no-cache"} Now, I copied the above code from the guide. The two code sections I edited mentioned in the error message I will paste as is below. class PostsController < ApplicationController # GET /posts # GET /posts.xml before_filter :find_post, :only => [:show, :edit, :update, :destroy] def index @posts = Post.find(:all) # <= the line 9 referred to in error message respond_to do |format| format.html # index.html.erb format.xml { render :xml => @posts } end end class Post < ActiveRecord::Base validates_presence_of :name, :title validates_length_of :title, :minimum => 5 has_many :comments has_many :tags accepts_nested_attributes_for :tags, :allow_destroy => :true , # <= problem :reject_if => proc { |attrs| attrs.all? { |k, v| v.blank? } } end Also here is gem local gem list. I do note that they are a bit out of date, but the default Rails install any of the school machines (an environment likely for my exam) is basically 'gem install rails --version 2.2.2' and since they are windows machines, they come with all the normal windows ruby gems that comes with the ruby installer. However, I am running this off a Debian virtual machine of mine, but trying to set it up similarly and I figured the windows ruby gems wouldn't change anything in Rails. *** LOCAL GEMS *** actionmailer (2.2.2) actionpack (2.2.2) activerecord (2.2.2) activeresource (2.2.2) activesupport (2.2.2) gem_plugin (0.2.3) hpricot (0.8.2) linecache (0.43) log4r (1.1.7) ptools (1.1.9) rack (1.1.0) rails (2.2.2) rake (0.8.7) sqlite3-ruby (1.2.3) So any ideas on what the problem is? Thanks in advanced.

  • Internet Explorer 10 auto-correct randomly capitalises words

    - by Andreas Rejbrand
    I use Internet Explorer 10 on my Windows 7 laptop (because the fingerprint browser add-on only works in IE). I have noticed that IE 10 has a built-in spellchecker, which is great. Now, I write about 90 % English and 10 % Swedish on web sites, so it is somewhat unfortunate that it isn't possible to change the spell-checker language 'on-the-fly'. But that's a minor issue. The main problem is that, when I write English comments, the spell-checker (apparently randomly) capitalises some Words. For instance, the 'words' of the previous sentence was changed automatically to 'Words'. Another Word that is Always capitalised is Before. (Yes, the Three Words that are incorrectly capitalised in the previous sentence are due to the auto-correct 'feature', and apparently 'three' is also a problematic word.) Is this really something that happens to every (bilingual) user? Is there any way to fix the issue (preferably without disabling the spell-checker altogether)?

  • Monitoring Dell/HP Servers Running ESXi (Free)

    - by Untalented
    What are you all doing to monitor ESXi servers that run the free edition? With the lack of SNMP support, it seems fairly limited to me. What'd I'd like to be able to do is get some type of alert when a drive or other hardware fails. I've seen a few articles on getting OpenManage installed on an ESXi box (to rebuild an array), but it seems to be quite a pain as well. Even if I get OpenManage working, I won't have alerts without SNMP. Any comments, input, or guidance would be greatly appreciated.

  • Sending jpegs by tcp socket...sometimes incomplete.

    - by Guy
    Vb.net Hi I've been working on a project for months now (vb 2008 express). There is one final problem which I can't solve. I need to send images to a client from a 'server'(listener). The code below works most of the time but sometimes the image is incomplete. I believe this might be something to do with the tcp packet sizes varying, maybe limited by how busy it is out there on the net. I have seen examples of code that splits the image into chunks and sends them out, but I can't get them to work maybe because I'm using a different vb version. The pictures to be sent are small 20k max. Any working code examples would be wonderful. I have been experimenting and failing with this final hurdle for weeks. Thanks in anticipation. Client----- Sub GetPic() '------- Connect to Server ClientSocket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, _ ProtocolType.Tcp) ClientSocket.Connect(Epoint) '------- Send Picture Request Dim Bytes() As Byte = System.Text.ASCIIEncoding.ASCII.GetBytes("Send Picture") ClientSocket.Send(Bytes, Bytes.Length, SocketFlags.None) '------- Receive Response Dim RecvBuffer(20000) As Byte Dim Numbytes As Integer Numbytes = ClientSocket.Receive(RecvBuffer) Dim Darray(Numbytes) As Byte Buffer.BlockCopy(RecvBuffer, 0, Darray, 0, Numbytes) '------- Close Connection ClientSocket.Shutdown(SocketShutdown.Both) ClientSocket.Close() '------- Dim MStrm = New MemoryStream(Darray) Picture = Image.FromStream(MStrm) End Sub Listener----- 'Threaded from a listener Sub ClientThread(ByVal Client As TcpClient) Dim MStrm As New MemoryStream Dim Rbuffer(1024) As Byte Dim Tbyte As Byte() Dim NStrm As NetworkStream = Client.GetStream() Dim I As Integer = NStrm.Read(Rbuffer, 0, Rbuffer.Length) Dim Incoming As String = System.Text.Encoding.ASCII.GetString(Rbuffer, 0, I) If Incoming = "Send Picture" then Picture Save(MStrm, Picture.RawFormat) Tbyte = MStrm.ToArray NStrm.Write(Tbyte, 0, Tbyte.Length) End if Client.Close() End Sub

  • Passing data structures to different threads

    - by Robb
    I have an application that will be spawning multiple threads. However, I feel there might be an issue with threads accessing data that they shouldn't be. I'm relatively new to threading so bare with me. Here is the structure of the threaded application (sorry for the crudeness): MainThread / \ / \ / \ Thread A Thread B / \ / \ / \ / \ / \ / \ Thread A_1 Thread A_2 Thread B_1 Thread B_2 Under each lettered thread (which could be many), there will only be two threads and they are fired of sequentially. The issue i'm having is I'm not entirely sure how to pass in a datastructure into these threads. So, the datastructure is created in MainThread, will be modified in the lettered thread (Thread A, etc) specific to that thread and then a member variable from that datastructure is sent to Letter_Numbered threads. Currently, the lettered thread class has a member variable and when the class is constructed, the datastructure from mainthread is passed in by reference, invoking the copy constructor so the lettered thread has it's own copy to play with. The lettered_numbered thread simply takes in a string variable from the data structure within the lettered thread. My question is, is this accceptable? Is there a much better way to ensure each lettered thread gets its own data structure to play with? Sorry for the somewhat poor explanation, please leave comments and i'll try to clarify.

  • Monorail - Form submission using GET instead of POST

    - by Septih
    Hello, I'm writing some additions to a Castle MonoRail based site involving an Add and an Edit form. The add form works fine and uses POST but the edit form uses GET. The only major difference I can see is that the edit method is called with the Id of the object being edited in the query string. When the submit button is pressed on the edit form, the only argument passed is this object Id again. Here is the code for the edit form: <form action="edit.ashx" method="post"> <h3>Coupon Description</h3> <textarea name="comments" width="200">$comments</textarea> <br/><br/> <h3>Coupon Actions</h3> <br/> <div>Give Stories</div> <ul class="checklist" style="overflow:auto;height:144px;width:100%"> #foreach ($story in $stories.Values) <li> <label> #set ($associated = "") #foreach($storyId in $storyIds) #if($story.Id == $storyId) #set($associated = " checked='true'") #end #end <input type="checkbox" name="chk_${story.Id}" id="chk_${story.Id}" value="true" class="checkbox" $associated/> $story.Name </label> </li> #end </ul> <br/><br/> <div>Give Credit Amount</div> <input type="text" name="credit" value="$credit" /> <br/><br/> <h3>Coupon Uses</h3> <input type="checkbox" name="multi" #if($multi) checked="true" #end /> Multi-Use Coupon?<br/><br/> <b>OR</b> <br/> <br/> Number of Uses per Coupon: <input type="text" name="uses" value="$uses" /> <br/> <input type="submit" name="Save" /> </form> The differences between this and the add form is the velocity stuff to do with association and the values of the inputs being from the PropertyBag. The Method dealing with this on the controller starts like this: public void Edit(int id) { Coupon coupon = Coupon.GetRepository(User.Site.Id).FindById(id).Value; if(coupon == null) { RedirectToReferrer(); return; } IFutureQueryOfList<Story> stories = Story.GetRepository(User.Site.Id).OnlyReturnEnabled().FindAll("Name", true); if (Params["Save"] == null) { ... } } It reliably gets called but a breakpoint on the Params["Save"] lets me see that the HttpMethod is "GET" and the only arguments passed (In the Form and the Request) are the object Id and additional HTTP headers. At the end of the day I'm not that familiar with MonoRail and this may be a stupid mistake on my behalf, but I would very much appreciate being made a fool out of if it fixes the problem! :) Thanks

  • How to open a second instance of the pdf x-change viewer?

    - by rumtscho
    Every time I open a new document in the pdf x-change viewer, it gets opened in the same window. I want to place different documents on different places on the screen (independently of each other, not just tiling the window for side-by-side view), but cannot do it. Even going to the start menu and starting the reader again doesn't open a new instance of the application. Can I force the program to open a new instance or a new independent window? If this is impossible, which other free reader does what I need and also lets me make changes to the file? I don't need to edit the text itself, but I want to be able to add comments, underline and highlight text, and add some graphic elements (e.g. a circle or a freehand line).

  • Auto Log-Off Windows users - Windows 2003 domain

    - by thehatter
    I am trying to make windows clients automatically log off after some time, I have been trying to use the winexit.scr which I have seen working else where in a similar environment. After working though these instructions (I did read the comments and notice the original ADM provided is buggy) I've had no joy what so ever! Winexit.scr refuses to read any settings in the registry, even while using a test account I can access the required reg key(s); edit, add, and remove values. Essentially winexit.scr always uses it's default values: 30 second timeout, no forced log-out. What I really want is a 30 minute timeout with a forced log-out, closing all the users apps etc. I've tried removing and re-adding the ADM template, creating the GPO from scratch several times, giving various registry permissions - including full control to "Everybody" just for fun! Oh, clients are all win XP SP3, DC is win 2003 R2 SP2. So, can anybody suggest something? Cheers!

  • Ubuntu: disable udev's persistent-net-generator.rules

    - by Luke404
    I'm using Ubuntu 12.04 LTS server edition and I am modifying /etc/udev/rules.d/70-persistent-net.rules to define my own mappings of ethernet interfaces to MAC addresses; that file is initially generated by rules in /lib/udev/rules.d/75-persistent-net-generator.rules at system installation time (or at the first boot, I actually don't know and it doesn't matter here). How can I be sure that my edited version will never ever be overwritten by anything? Removing the persistent-net-generator, as suggested on some websites, is not the Right Thing™ to do as told by comments in the file itself: it will be overwritten by any update of the udev package. I'm looking for a more formally correct way to disable it. Is it enough to just make sure that /etc/udev/rules.d/70-persistent-net.rules does exist? Maybe there are other events that could trigger its regeneration? (eg. adding or removing ethernet interfaces to the system?)

  • Search and replace hundreds of strings in tens of thousands of files?

    - by C Johnson
    I am looking into changing the file name of hundreds of files in a (C/C++) project that I work on. The problem is our software has tens of thousands of files that including (i.e. #include) these hundreds of files that will get changed. This looks like a maintenance nightmare. If I do this I will be stuck in Ultra-Edit for weeks, rolling hundreds of regex's by hand like so: ^\#include.*["<\\/]stupid_name.*$ with #include <dir/new_name.h> Such drudgery would be worse than peeling hundreds of potatoes in a sunken submarine in the antarctic with a spoon. I think it would rather be ideal to put the inputs and outputs into a table like so: stupid_name.h <-> <dir/new_name.h> stupid_nameb.h <-> <dir/new_nameb.h> stupid_namec.h <-> <dir/new_namec.h> and feed this into a regular expression engine / tool / app / etc... My Ultimate Question: Is there a tool that will do that? Bonus Question: Is it multi-threaded? I looked at quite a few search and replace topics here on this website, and found lots of standard queries that asked a variant of the following question: standard question: Replace one term in N files. as opposed to: my question: Replace N terms in N files. Thanks in advance for any replies.

  • Program broke my windows. Everything randomly minimizes even after multiple restarts

    - by Xitcod13
    I just installed LoL (league of legends) on my computer. The problem is that almost every time after I play the game, it minimizes all my windows which is really annoying. What is worse however is that afterwards other programs do this as well. In the internet browser doesn't minimize but it does loose focus. For example when i type it randomly looses focus and i have to click on the browser window again to it registers my typing. Is there any way to fix this? What can cause such a strange behavior?? In addition this problem persists even after restarting my computer. I previously thought it was internet driver. I no longer think so this happened right after I started playing the game and seems pretty persistent. Please read the comments for further information. This pretty much renders my computer useless. Even typing this takes a huge effort.

  • Thunderbird: moving email from local Junk folder to IMAP folder yields "Message contains invalid header"

    - by Peltier
    Whenever I try to move an email from a local Junk folder to an IMAP folder in Thunderbird, I get the following error message: The current command did not succeed. The mail server responded: Message contains invalid header If Thunderbird's Junk folder is an IMAP folder on the server, then after Thunderbird has moved messages to that folder, I can successfully move messages from Junk back into to some other IMAP folder. However, if the Junk folder is not on the server, then moving a message from the local Junk folder to an IMAP folder yields the aforementioned error. The only interesting thing I've found about this error is "Message contains invalid header" from the MozillaZine Knowledge Base. That article officially is about importing folders from another email client, and does not mention the Junk filter as another possible cause. However the proposed solution is not very helpful since it requires manual editing of the message box files. Any better ideas? EDIT: make sure you read the comments before answering the question.

  • Run script when POST data is sent to Apache

    - by Nathan Adams
    Among my several years of running servers there seems to be a pattern with most spam activity. My question/idea is that is there a way to tell Apache to run a script when POST data is detected? What I would want to do is perform a reverse DNS lookup on the client's IP address, and then perform a DNS lookup on the hostname in the PTR record. Afterwards, perform some checks, excuse the pseudo-code: if PTR does not exist: deny POST request if IP of PTR hostname = client's IP Allow POST request else deny POST request Though I don't care about GET requests, even though they can be just as malicious, this idea is targeted towards spam comments which use POST data to send the comment data to the web server. In order to make sure there isn't much of a time delay, I would run my own recursive DNS server. Please do note, this isn't meant to be a sliver bullet to spam, but it should decrease the volume. Possible or impossible?

  • Aironet 1200's Auto-Channel Feature: When should it be used?

    - by Josh Brower
    In our building we have around 25 1200 series Aironets, with a bit of overlap in some areas. Up until this point, we have had them deployed in alternating 1/6/11 channels, but we are wondering if we would get better performance if we used the auto-channel select feature. In looking around, I have seen comments that this feature should not be used as the WAP does a channel scan only on the radio startup, but I have not found this in any Cisco docs. Anybody have anymore information, or real-world experience with this feature? Thanks! -Josh

  • CISCO WS-C4948-10GE SFP+?

    - by Brian Lovett
    I have a pair of CISCO WS-C4948-10GE's that we need to connect to a new switch that has SFP+ and QSFP ports. Is there an X2 module that supports this? If so, can someone name the part number that will work? I have found some information, but want to make sure I have the correct part number for our exact switches. Per the discussion in the comments, I believe I have a better understanding of things now. Would I be correct in saying that I need these SR modules on the cisco side: [url]http://www.ebay.com/itm/Cisco-original-used-X2-10GB-SR-V02-/281228948970?pt=LH_DefaultDomain_0&hash=item417a8d35ea[/url] Then, on the switch with sfp+ ports, I can pick up an SR to SFP+ transceiver like this: [url]http://www.advantageoptics.com/SFP-10G-SR_lp.html?gclid=CKP4s-G27b4CFXQiMgodLD8AQA[/url] and finally, an SR calbe such as this: [url]http://www.colfaxdirect.com/store/pc/viewPrd.asp?idproduct=1551[/url] Am I on the right track here?

  • 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!

  • Python C API from C++ app - know when to lock

    - by Alex
    Hi Everyone, I am trying to write a C++ class that calls Python methods of a class that does some I/O operations (file, stdout) at once. The problem I have ran into is that my class is called from different threads: sometimes main thread, sometimes different others. Obviously I tried to apply the approach for Python calls in multi-threaded native applications. Basically everything starts from PyEval_AcquireLock and PyEval_ReleaseLock or just global locks. According to the documentation here when a thread is already locked a deadlock ensues. When my class is called from the main thread or other one that blocks Python execution I have a deadlock. Python Cfunc1() - C++ func that creates threads internally which lead to calls in "my class", It stuck on PyEval_AcquireLock, obviously the Python is already locked, i.e. waiting for C++ Cfunc1 call to complete... It completes fine if I omit those locks. Also it completes fine when Python interpreter is ready for the next user command, i.e. when thread is calling funcs in the background - not inside of a native call I am looking for a workaround. I need to distinguish whether or not the global lock is allowed, i.e. Python is not locked and ready to receive the next command... I tried PyGIL_Ensure, unfortunately I see hang.
