• measure the response time of a link

  - by Ahoura Ghotbi

  I am trying to create a simple load balance script and I was wondering if it is possible to find the response time of a server live? By that I mean is it possible to measure how long it takes for a server to respond after the request has been sent out? What I am trying to do is fairly simple, I want to send a request to a link/server and do a count down, if the server took more than 5 seconds to reply, I would like to fall on the backup server. Note that it doesnt have to be in pure php, I wouldnt mind using other languages such as javascript, C/C++, asp, but I prefer to do it in PHP. if it is possible to do the task, could you just point me to the right direction so I can read up on it. Clarification What I want to do is not to download a file and see how long it took, my servers have high load and it takes a while for them to respond when you click on a file to download, what I want to do is to measure the time it takes the server to respond (in this situation, its the time it takes the server to respond and allow the user to download the file), and if it takes longer than x seconds, it should fall back on a backup server.

• bind event handler on keydown listen function JavaScript jQuery

  - by user1644123

  I am trying to bind a handler to an event. The event is a keydown function. The handler will listen for hit variables to produce one of two conditions. The 1st condition (odd number of hits) will perform 1 function, the 2nd (even number of hits) will perform another function. To elaborate, the 1st function will scroll to one element, the 2nd will scroll to another element. My syntax may be the wrong approach, but it works for the 1st condition, but not the 2nd. I think I have the conditional statement in the wrong place. How can I rewrite this to work as intended? Thank you kindly, in advance! $(document).keydown(function(e) { switch (e.which) { case 37: break; case 38: break; case 39: break; case 40: //bottom arrow key var hits = 0; if (hits % 2 !== 0) { $('#wrap').animate({ scrollTop: $("#scrollToHere").offset().top }, 2800); } else { $('#wrap').animate({ scrollTop: $("#scroll2ToHere").offset().top }, 2800); } hits++; return false; break; } })? *I moved "var hits = 0;" to the top, but it only works! But is there a way I can reset the whole thing after every two hits? I want to reset because when there is a bug and if I press a 3rd time it scrolls to the very top of the page, where there is no element to make it scroll to the top. Why would it scroll to the top of the page if I never scripted it to do so?? *

• Windows Phone period task, function not executing

  - by Special K.

  I'm trying to execute a code (to parse an XML to be more precisely, and after that I'll toast message the user with some new info's), but the class function AccDetailsDownloaded is not executed (is simply skipped), also the memory usage is ~2mb out of 6, here is my code: if (task is PeriodicTask) { getData(); } else { getData(); } // If debugging is enabled, launch the agent again in one minute. #if DEBUG_AGENT ScheduledActionService.LaunchForTest(task.Name, TimeSpan.FromSeconds(60)); #endif // Call NotifyComplete to let the system know the agent is done working. NotifyComplete(); } public void getData() { var settings = IsolatedStorageSettings.ApplicationSettings; string url = "http://example.com/example.xml"; if (!System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable()) { MessageBox.Show("No network connection available!"); return; } // start loading XML-data WebClient downloader = new WebClient(); Uri uri = new Uri(url, UriKind.Absolute); downloader.DownloadStringCompleted += new DownloadStringCompletedEventHandler(AccDetailsDownloaded); downloader.DownloadStringAsync(uri); string toastTitle = ""; toastTitle = "Periodic "; string toastMessage = "Mem usage: " + DeviceStatus.ApplicationPeakMemoryUsage + "/" + DeviceStatus.ApplicationMemoryUsageLimit; // Launch a toast to show that the agent is running. // The toast will not be shown if the foreground application is running. ShellToast toast = new ShellToast(); toast.Title = toastTitle; toast.Content = toastMessage; toast.Show(); } void AccDetailsDownloaded(object sender, DownloadStringCompletedEventArgs e) { if (e.Result == null || e.Error != null) { MessageBox.Show("There was an error downloading the XML-file!"); } else { string toastTitle = ""; toastTitle = "Periodic "; string toastMessage = "Mem usage: " + DeviceStatus.ApplicationPeakMemoryUsage + "/" + DeviceStatus.ApplicationMemoryUsageLimit; // Launch a toast to show that the agent is running. // The toast will not be shown if the foreground application is running.

• Changing drag cursor in VirtualTreeView

  - by Coder12345

  When using VirtualTreeView drag operation by default is [doCopy,doMove]. Move operation is indicated by arrow pointer with small box and Copy operation is indicated by same pointer icon but with added [+] next to it. By default VT uses copy operation and if you press modifier key (SHIFT key) it modifies operation to move therefore removing the [+] from pointer. Here is what I need: reverse the operations (default would be move, with modifier key pressed - copy) and thus reverse pointer arrow too replace modifier key - CTRL instead of SHIFT read in an event which of the two operations occurred and start copy or move operation Any pointers into right direction(s) appreciated.

• Writing a batch script to perform differently on different days?

  - by Tom

  I am in the process of setting up a batch script to do a specified action if the script was run on a weekday, and an alternate action if run on the weekend. I am almost completely unfamiliar with writing batch scripts, but I know how to write my entire script except the logic I describe above. Can someone please answer both if it is possible, and if it is at least a framework of how to implement it. Thanks in advance.

• Process AJAX response with long runing tasks

  - by mpz

  I have long time task in controller action. I use delayed job for it. (Also in heroku it is good practice for perfomance - dyno must work for small time in each request) But my client need result of it work and users can wait on that task. It is more clear: no any addition models or records in it, simple view and js... I think about such way: On client run AJAX with very long timeout (5 min for example) Client make request to server as usual On controller in action1 def start_work (with delay work setup) i need NO any response to client After work performs (delay job finished) i need run new action2 with response to client Client recieve response after about 1-5 min It is possible?

• Python Speeding Up Retrieving data from extremely large string

  - by Burninghelix123

  I have a list I converted to a very very long string as I am trying to edit it, as you can gather it's called tempString. It works as of now it just takes way to long to operate, probably because it is several different regex subs. They are as follow: tempString = ','.join(str(n) for n in coords) tempString = re.sub(',{2,6}', '_', tempString) tempString = re.sub("[^0-9\-\.\_]", ",", tempString) tempString = re.sub(',+', ',', tempString) clean1 = re.findall(('[-+]?[0-9]*\.?[0-9]+,[-+]?[0-9]*\.?[0-9]+,' '[-+]?[0-9]*\.?[0-9]+'), tempString) tempString = '_'.join(str(n) for n in clean1) tempString = re.sub(',', ' ', tempString) Basically it's a long string containing commas and about 1-5 million sets of 4 floats/ints (mixture of both possible),: -5.65500020981,6.88999986649,-0.454999923706,1,,,-5.65500020981,6.95499992371,-0.454999923706,1,,, The 4th number in each set I don't need/want, i'm essentially just trying to split the string into a list with 3 floats in each separated by a space. The above code works flawlessly but as you can imagine is quite time consuming on large strings. I have done a lot of research on here for a solution but they all seem geared towards words, i.e. swapping out one word for another. EDIT: Ok so this is the solution i'm currently using: def getValues(s): output = [] while s: # get the three values you want, discard the 3 commas, and the # remainder of the string v1, v2, v3, _, _, _, s = s.split(',', 6) output.append("%s %s %s" % (v1.strip(), v2.strip(), v3.strip())) return output coords = getValues(tempString) Anyone have any advice to speed this up even farther? After running some tests It still takes much longer than i'm hoping for. I've been glancing at numPy, but I honestly have absolutely no idea how to the above with it, I understand that after the above has been done and the values are cleaned up i could use them more efficiently with numPy, but not sure how NumPy could apply to the above. The above to clean through 50k sets takes around 20 minutes, I cant imagine how long it would be on my full string of 1 million sets. I'ts just surprising that the program that originally exported the data took only around 30 secs for the 1 million sets

• Writing to a file in a servlet

  - by ankur verma

  I am working in a servlet and has this code : public void doPost(blah blah){ response.setContentType("text/html"); String datasent = request.getParameter("dataSent"); System.out.println(datasent); try{ FileWriter writer = new FileWriter("C:/xyz.txt"); writer.write("hello"); System.out.println("I wrote"); }catch(Exception ex){ ex.printStackTrace(); } response.getWriter().write("I am from server"); } But everytime it is throwing an error saying Access Denied..

• Jobs magically disappear from queue (delayed_job mongoid 2 on heroku)

  - by Hayk Saakian

  lets say i do something like arrs = Article.where(:body => nil) i'll have arrs.count is let's say 900 and i do arrs.each do |ar| ar.delay.download_via_diffbot #a method that takes some time, does some http, and writes a non-nil value to ar.body end now i'll watch the logs, and a wait a few minutes on ~5 dynos do the jobs, and do a count again: arrs.count is now ~800 so wtf, i thought i just told my workers to do ~900 jobs, what happened to the other 800? i can confirm that i'm only making ~100 HTTP requests b/c the api reporting shows me this, also simply watching the logs is telling enough that 900 jobs are not happening.

• How find all overlapping circles from radius of central circle?

  - by roza

  How to do an intersection or overlap query in mongo shell - what circles overlap my search region? Within relate only to the center position but doesn't include radius of the other circles in searched scope. Mongo: # My bad conception: var search = [[30, 30], 10] db.places.find({circle : {"$within" : {"$center" : [search]}}}) Now I can obtain only this circles within central point lies in searched area of circle: Ruby: # field :circle, type: Circle # eg. [ [ 30, 30 ], 10 ] field :radius, type: Integer field :location, :type => Array, :spatial => true spatial_index :location Places.within_circle(location: [ [ 30, 30 ], 10 ]) # {"$query"=>{"location"=>{"$within"=>{"$center"=>[[30, 30], 10]}}} I created example data with additional location (special index) and radius instead circle because circle isn't supported by mongodb geo index: { "_id" : 1, "name" : "a", "circle" : [ [ 5, 5 ], 40 ], "latlng" : [ 5, 5 ], "radius" : 40 } { "_id" : 2, "name" : "b", "circle" : [ [ 10, 10 ], 5 ], "latlng" : [ 10, 10 ], "radius" : 5 } { "_id" : 3, "name" : "c", "circle" : [ [ 20, 20 ], 5 ], "latlng" : [ 20, 20 ], "radius" : 5 } { "_id" : 4, "name" : "d", "circle" : [ [ 30, 30 ], 50 ], "latlng" : [ 30, 30 ], "radius" : 50} { "_id" : 5, "name" : "e", "circle" : [ [ 80, 80 ], 30 ], "latlng" : [ 80, 80 ], "radius" : 30} { "_id" : 6, "name" : "f", "circle" : [ [ 80, 80 ], 20 ], "latlng" : [ 80, 80 ], "radius" : 20} Desired query result: { "_id" : 1, "name" : "a", "circle" : [ [ 5, 5 ], 40 ], "latlng" : [ 5, 5 ], "radius" : 40 } { "_id" : 3, "name" : "c", "circle" : [ [ 20, 20 ], 5 ], "latlng" : [ 20, 20 ], "radius" : 5 } { "_id" : 4, "name" : "d", "circle" : [ [ 30, 30 ], 50 ], "latlng" : [ 30, 30 ], "radius" : 50} { "_id" : 5, "name" : "e", "circle" : [ [ 80, 80 ], 30 ], "latlng" : [ 80, 80 ], "radius" : 30} Solution below assumes that I get all rows and then filter on the ruby side my radius but it returns only: { "_id" : 4, "name" : "d", "circle" : [ [ 30, 30 ], 50 ], "latlng" : [ 30, 30 ], "radius" : 50}

• Mostly PJAX site with some AngularJS

  - by jrhicks

  I have a site using PJAX all over the place and I have a few pages that are using AngularJS. For the AngularJS pages I would like to continue to use PJAX to get all the benefits associated with not reloading the entire HTML page, assets etc. Unfortunately, PJAX just loads some HTML into the page and doesn't fire any javascript. This is okay, because I can fire the javascript manually on pjax success, but I can't quite figure out what makes AngularJS initialize. For a simple scenario, lets say I AJAX the following HTML into a page. Also assume, the page already had Angular.js included. What could I call to have the following behave like an Angular App? <div> <label>Name:</label> <input type="text" ng-model="yourName" placeholder="Enter a name here"> <hr> <h1>Hello {{yourName}}!</h1> </div> Thanks

• Debugging fortran code in Eclipse with Photran and GDB debugger: missing symbols

  - by tvandenbrande

  I have a program, written in fortran90, previously successfully compiled on a compaq compiler and working, that I'm now trying to compile with gfortran. I can compile the code to an .exe and run it. It works fine until a certain point in the routine and then an error is thrown. My current configuration: Windows 7 Eclipse Juno with CDT Photran Cygwin installation with gfortran compiler and GDB debugger (gdb.exe) Configurations for the debugger: GDB command set: Standard (Windows) Protocol: mi Shared libraries: don't load shared library symbols automatically (when activating this, no changes are noted). When running the debug command I get the following output: .gdbinit: No such file or directory. Reading symbols from /cygdrive/c/Users/thys/Documents/doctoraat/12_in progress/Hamfem/Debug/Hamfem.exe...done. auto-solib-add on Undefined command: "auto-solib-add". Try "help".

[New Thread 5816.0x1914] [New Thread 5816.0x654] Basicly that leaves me with 2 questions: Where can I find the .gdbinit file in the cygwin installation? Are there any other possible errors in my setup, or points to think about?

• Writing an unthemed view while still using Orchard shapes and helpers

  - by Bertrand Le Roy

  This quick tip will show how you can write a custom view for a custom controller action in Orchard that does not use the current theme, but that still retains the ability to use shapes, as well as zones, Script and Style helpers. The controller action, first, needs to opt out of theming: [Themed(false)] public ActionResult Index() {} .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Then, we still want to use a shape as the view model, because Clay is so awesome: private readonly dynamic _shapeFactory; public MyController(IShapeFactory shapeFactory) { _shapeFactory = shapeFactory; } [Themed(false)] public ActionResult Index() { return View(_shapeFactory.MyShapeName( Foo: 42, Bar: "baz" )); } As you can see, we injected a shape factory, and that enables us to build our shape from our action and inject that into the view as the model. Finally, in the view (that would in Views/MyController/Index.cshtml here), just use helpers as usual. The only gotcha is that you need to use “Layout” in order to declare zones, and that two of those zones, Head and Tail, are mandatory for the top and bottom scripts and stylesheets to be injected properly. Names are important here. @{ Style.Include("somestylesheet.css"); Script.Require("jQuery"); Script.Include("somescript.js"); using(Script.Foot()) { <script type="text/javascript"> $(function () { // Do stuff }) </script> } } <!DOCTYPE html> <html> <head> <title>My unthemed page</title> @Display(Layout.Head) </head> <body> <h1>My unthemed page</h1> <div>@Model.Foo is the answer.</div> </body> @Display(Layout.Tail) </html> Note that if you define your own zones using @Display(Layout.SomeZone) in your view, you can perfectly well send additional shapes to them from your controller action, if you injected an instance of IWorkContextAccessor: _workContextAccessor.GetContext().Layout .SomeZone.Add(_shapeFactory.SomeOtherShape()); Of course, you’ll need to write a SomeOtherShape.cshtml template for that shape but I think this is pretty neat.

• IIS 8 FTP

  This post began its life as ‘What’s new in IIS 8 FTP’ but has since morphed into something quite different. As the ultimate goal is still to talk about what’s new with FTP for IIS 8, I have retained IIS, 8, and FTP in the title but nothing more.

• Remote network traffic not passing through VPN

  - by John Virgolino

  We have the following topology: LAN A LAN B LAN C 10.14.0.0/16 <-VPN-> 10.18.0.0/16 --- SONICWALL <-VPN-> M0N0WALL --- 10.32.0.0/16 Traffic between LAN A and LAN B works perfectly. Traffic between LAN C and LAN B works perfectly. Traffic between LAN A and LAN C, not so much. LAN A's gateway has a route to LAN C that points to the Sonicwall. The Sonicwall has a route to LAN A pointing to the VPN gateway connecting LAN B to LAN A. Tracing packets on the Sonicwall shows the LAN C destined traffic to arrive on the Sonicwall, but it does not forward the traffic, it dies there. Traffic from LAN B gets forwarded. Tracing packets on the Sonicwall while sending traffic from LAN C destined for LAN A shows nothing. This tells me that the M0N0WALL is not forwarding traffic for the 10.14.0.0 network and the Sonicwall is not forwarding from 10.14.0.0. The SA on the Sonicwall terminates on the WAN ZONE and is defined to use an address group that incorporates both the 10.14.0.0 and 10.18.0.0 networks. The M0N0WALL is configured for the 10.18.0.0 network and I have tried with both a static route to 10.14.0.0 and without on the M0N0WALL. I tried manually adding the 10.14.0.0 network to the SA on the M0N0WALL, but that really aggravated it and the SA never came up, so I reverted. I have checked all the firewall rules to make sure nothing is blocked. All of the Sonicwall auto-added rules look right. Specs: Sonicwall TZ200, Enhanced OS M0N0WALL v1.32 I'm at a loss at this point. Any help would be appreciated.

• Disabling the shell of user "daemon" (/bin/false)

  - by BurninLeo

  on a Linux system there are lot's of users by default: daemon, bin, sys, games, etc. According to my /etc/passwd most of these users have a shell assigned (/bin/sh) which seems some kind of insecure to me. My naive thinking would say: Only give those users a shell that may login to the server. Is my thinking wrong? If not completely wrong: Can I disable the shell for "daemon" and "www-data" without having side effects (e.g. the system wont start or the Apache PHP cannot excute system calls)? Thanks for your hints!

• Trying to Set up SMTP Server on WIndows Server 2012

  - by datc

  I'm working on a website, and I need to test the functionality of sending email messages from ASP.NET, something like this: Dim msg As New MailMessage("email1", "email2") msg.Subject = "Subject"<br> msg.IsBodyHtml = True<br> msg.Body = "Click <a href='site'>here</a>." Dim client As SmtpClient = New SmtpClient() client.Host = "My-Server"<br> client.Port = 25<br> client.DeliveryMethod = SmtpDeliveryMethod.Network<br> client.Send(msg) This is running from a Windows 8 workstation. I've installed SMTP server on my Windows Server 2012 machine. The mail shows up in the mailroot/Queue folder and sits there, eventually getting deposited into Badmail. Now I have AT&T U-verse at home, and a few devices connected to the gateway, including let's call it "My-Server." When I run SmtpDiag from say, datc@... to [email protected] I get SOA serial number match passed, Local DNS (99-135-60-233.lightspeed.bcvloh.sbcglobal.net) & Remote DNS (hotmail.com) tests *not* passed, and ultimately, Connecting to the server failed. Error: 10060. Failed to submit mail to mx2.hotmail.com error. When I set My-Server's IP to static and equal to the external IP, 99.135.60.233, and again run SmtpDiag, I get SOA, Local DNS, and Remote DNS tests passed, but the same 10060 error. Same for yahoo.com, gmail.com, and so forth. Is it my ISP's job to fix this? Some PTR record missing somewhere? Is it at all possible to have a home-based SMTP server? All I want is to test my email code. Perhaps, my IP address is just not "trusted" somehow. Thanks.

• Puppet yum repo - Pull down 2.7.x vs 3.0.x

  - by Mike Purcell

  So a few weeks ago I started on the path to using puppet to automate all the configs/services. At the time I was using the EPEL repo, which installed version 2.6.x. After some reading I was trying to gain access to the flatten method available via the puppet stdlib, and thought it was available by default in the newer 2.7.x version. So I added a puppet repo with the following settings: [puppetlabs] name=Puppet Labs Packages baseurl=http://yum.puppetlabs.com/el/$releasever/products/$basearch/ enabled=1 gpgcheck=1 gpgkey=http://yum.puppetlabs.com/RPM-GPG-KEY-puppetlabs The problem with this, is it installed v3.0.x instead of 2.7.x. And apparently 3.0.x is a major upgrade which was released only a few weeks ago. Obviously I would prefer to use the 2.7.x for the next few months while PuppetLabs fix any defects which will inevitably arise after a major version. So my question is, what setting can I add to the puppet repo config to pull down only the 2.7.x branch and not the 3.0.x branch?

• Intermittent apt-get 'no installation candidate' error on fabric deploy

  - by jberryman

  I'm experiencing a strange issue with a fabric script I'm using to bootstrap a server on EC2. I launch a stock Ubuntu 12.04 AMI, wait for it to start, then proceed with: with settings(host_string="ubuntu@%s" % i.dns_name, connection_attempts=30): sudo('apt-get -qy update') sudo('apt-get -qy install --no-install-recommends mdadm') # don't install postfix #etc... The apt-get update appears to run fine and gives no errors, however (2/3 of the time or so) installing mdadm throws a "no installation candidate" error. When I ssh into the server and run apt-get install mdadm I get the same error. Running apt-get update by hand, then the package installs fine. Any ideas on what might be happening, or ideas for debugging?
