• Strategies for testing reactive, asynchronous code

  - by Arne

  I am developing a data-flow oriented domain-specific language. To simplify, let's just look at Operations. Operations have a number of named parameters and can be asked to compute their result using their current state. To decide when an Operation should produce a result, it gets a Decision that is sensitive to which parameter got a value from who. When this Decision decides that it is fulfilled, it emits a Signal using an Observer. An Accessor listens for this Signal and in turn calls the Result method of the Operation in order to multiplex it to the parameters of other Operations. So far, so good, nicely decoupled design, composable and reusable and, depending on the specific Observer used, as asynchronous as you want it to be. Now here's my problem: I would love to start coding actual Tests against this design. But with an asynchronous Observer... how should I know that the whole signal-and-parameters-plumbing worked? Do I need to use time outs while waiting for a Signal in order to say that it was emitted successfully or not? How can I be, formally, sure that the Signal will not be emitted if I just wait a little longer (halting problem? ;-)) And, how can I be sure that the Signal was emitted because it was me who set a parameter, and not another Operation? It might well be that my test comes to early and sees a Signal that was emitted way before my setting a parameter caused a Decision to emit it. Currently, I guess the trivial cases are easy to test, but as soon as I want to test complex many-to-many - situations between operations I must resort to hoping that the design Just Works (tm)...

• Server Unable to Capture the POST Data sent from another server by Redirecting the URL

  - by user1749092

  Recently i started working on the Payment Gateway( further spelled as 'PG') process for my site. And for the process we have to send the Post data by form to PG server by redirecting to there page and by response from the PG about the Transaction they are sending POST data by redirecting the URL to our server page, the problem arises here, as my server unable to retrieve the POST Data sent from PG server. As i am coding in PHP, i tried to print all the response coming from PG by print_r($_POST); and even tried with print_r($_REQUEST);. I didn't found any data printing except the PHPSESSID and some other data array. As for the confirmation I checked wether they sending the Data or not by the IE addon as "TamperIE" where it is showing the all the POST Data sending from there server. But it is not at all coming to our server. And I tried this process on some other Server, there i able to get the POST response but not with currently working server. So please can you suggest me what might be the problem. Thanks!

• Creating transparent PNG with exact RGBA values

  - by rrowland

  I'm color-coding a transparent image to be read programatically. However, the image seems to be getting compressed and my code is reading color values other than the ones I mean to pass it. Concept This is the output I get, exporting as PNG-24. I programatically check each pixel for one of the six colors I use in creating the image: 0x00000F 0x0000F0 0x000F00 0x00F000 0x0F0000 0xF00000 Each color represents a different texture to apply. Top right (0x00000F) will pull texture from the tile to its top right and blend it at a ratio equal to the opacity of the pixel. The end goal is to create a hex tiled grid with differing textures that blend smoothly. What's happening It seems that when converting to PNG, Photoshop will change the RGBA to make it smoother, or just to help compression size. Parts that should be 250 red range anywhere from 150 to 255. Question Whether using PNG or another web-compatible format, I need to be able to save these pixel values, essentially instructions, loss-less and still maintain transparency. Is this possible in any format or will I need to re-think my approach?

  hi friends, I have text file with list of alphabets and numbers. I want to do sorting w.r.t this number using java. My text file looks like this: a---12347 g---65784 r---675 I read the text file and i split it now. But i dont know how to perform sorting . I am new to java. Please give me a idea. My output want to be g---65784 a---12347 r---675 Plese help me. Thanks in advance. My coding is String str = ""; BufferedReader br = new BufferedReader(new FileReader("counts.txt")); while ((str = br.readLine()) != null) { String[] get = str.split("----"); When i search the internet all suggest in the type of arrays. I tried. But no use.How to inlude the get[1] into array. int arr[]=new int[50] arr[i]=get[1]; for(int i=0;i<50000;i++){ for(int j=i+1;j<60000;j++){ if(arr[i]arr[j]){ System.out.println(arr[i]); } }

• How to get correct children ids using fields_for "parents[]", parent do |f| using f.fields_for :children, child ?

  - by Anatortoise House

  I'm editing multiple instances of a parent model in an index view in one form, as in Railscasts #198. Each parent has_many :children and accepts_nested_attributes_for :children, as in Railscasts #196 and #197 <%= form_tag %> <% for parent in @parents %> <%= fields_for "parents[]", parent do |f| <%= f.text_field :job %> <%= f.fields_for :children do |cf| %> <% cf.text_field :chore %> <% end %> <% end %> <% end %> <% end %> Given parent.id==1 f.text_field :job correctly generates <input id="parents_1_job" type="text" value="coding" size="30" name="parents[1][job]"> But cf.text_field :chore generates ids and names that don't have the parent index. id="parents_children_attributes_0_chore" name="parents[children_attributes][0][chore]" If I try passing the specific child object to f.fields_for like this: <% for child in parent.children %> <%= f.fields_for :children, child do |cf| %> <%= cf.text_field :chore %> <% end %> <% end %> I get the same. If I change the method from :children to "[]children" I get id="parents_1___children_chore" which gets the right parent_index but doesn't provide an array slot for the child index. "[]children[]" isn't right either: id="parents_1__children_3_chore" as I was expecting attributes_0_chore instead of 3_chore. Do I need to directly modify an attribute of the FormBuilder object, or subclass FormBuilder to make this work, or is there a syntax that fits this situation? Thanks for any thoughts.

• printSoln module problem

  - by dingo_d

  Hi I found in book:Numerical Methods in engineering with Python the module run_kut5, but for that module I need module printSoln, all provided in the book. Now I cp the code, made necessary line adjustments and so. The code looks like: # -*- coding: cp1250 -*- ## module printSoln ''' printSoln(X,Y,freq). Prints X and Y returned from the differential equation solvers using printput frequency ’freq’. freq = n prints every nth step. freq = 0 prints initial and final values only. ''' def printSoln(X,Y,freq): def printHead(n): print "\n x ", for i in range (n): print " y[",i,"] ", print def printLine(x,y,n): print "%13.4e"% x,f for i in range (n): print "%13.4e"% y[i], print m = len(Y) try: n = len(Y[0]) except TypeError: n = 1 if freq == 0: freq = m printHead(n) for i in range(0,m,freq): printLine(X[i],Y[i],n) if i != m - 1: printLine(X[m - 1],Y[m - 1],n) Now, when I run the program it says: line 24, in <module> m = len(Y) NameError: name 'Y' is not defined But I cp'd from the book :\ So now when I call the run_kut module I get the same error, no Y defined in printSoln... I'm trying to figure this out but I suck :( Help, please...

• JAVA - How to code Node neighbours in a Grid ?

  - by ke3pup

  Hi guys I'm new to programming and as a School task i need to implement BFS,DFS and A* search algorithms in java to search for a given Goal from a given start position in a Grid of given size, 4x4,8x8..etc to begin with i don't know how to code the neighbors of all the nodes. For example tile 1 in grid as 2 and 9 as neighbors and Tile 12 has ,141,13,20 as its neighbours but i'm struggling to code that. I need the neighbours part so that i can move from start position to other parts of gird legally by moving horizontally or vertically through the neighbours. my node class is: class node { int value; LinkedList neighbors; bool expanded; } let's say i'm given a 8x8 grid right, So if i start the program with a grid of size 8x8 right : 1 - my main will func will create an arrayList of nodes for example node ArrayList test = new ArrayList(); and then using a for loop assign value to all the nodes in arrayList from 1 to 64 (if the grid size was 8x8). BUT somehow i need t on coding that, if anyone can give me some details i would really appreciate it.

• C# WPF Unable to control Textboxes

  - by Bo0m3r

  I'm a beginner in coding into C#. While I'm launching a process I can't controls my textboxes. I found some answers on this forum but the explaination is a bit to difficult for me to implement it for my problem. I created a small program that will run a batch file to make a backup. While the backup is running I can't modify my textboxes, disabling buttons etc... I already saw that this is normal but I don't know how to implement the solutions. My last attempt was with Dispatcher.invoke as you can see below. public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); tb_Status.Text = "Ready"; } public void status() { Dispatcher.Invoke(DispatcherPriority.Send, new Action( () => { tb_Status.Text = "The backup is running!"; } ) ); } public void process() { try { Process p = new Process(); p.StartInfo.WindowStyle = ProcessWindowStyle.Minimized; p.StartInfo.CreateNoWindow = true; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.FileName = "Robocopy.bat"; p.Start(); string output = p.StandardOutput.ReadToEnd(); p.WaitForExit(); tb_Output.Text = File.ReadAllText("Backup\\log.txt"); } catch (Exception ex) { tb_Status.Text = ex.Message.ToString(); } } private void Bt_Start_Click(object sender, EventArgs e) { status(); Directory.CreateDirectory("Backup"); process(); tb_Status.Text = "The backup finished"; File.Delete("Backup\\log.txt"); } } } Any help is appreciated!

• ASP.NET 'Check all checkboxes' control

  - by RUiHAO

  I am using visual studio 2005 c#, and doing server side coding. I have a list of checkboxes in my gridview via checkbox template. I have tried to assign a checkbox in my header template, and assigned a checkbox_checkchange method to make it such that when the checkbox at the header is checked, the list of checkboxes in the template will be checked as well. However, it does not work and I am not able to spot the mistake. Below is my code for my checkbox in header template: protected void CheckAllCB_CheckedChanged(object sender, EventArgs e) { CheckBox chk = (CheckBox)GridView1.HeaderRow.FindControl("CheckAll"); if (chk.Checked) { for (int i = 0; i < GridView1.Rows.Count; i++) { CheckBox chkrow = (CheckBox)GridView1.Rows[i].FindControl("UserSelector"); chkrow.Checked = true; } } else { for (int i = 0; i < GridView1.Rows.Count; i++) { CheckBox chkrow = (CheckBox)GridView1.Rows[i].FindControl("UserSelector"); chkrow.Checked = false; } } } Thus I tried using a button to assign the checkall command instead. However, when I clicked on the button, the page does nothing but just refreshes itself. Below is my code for the checkall and uncheckall button: private void ToggleCheckState(bool checkState) { // Iterate through the Products.Rows property foreach (GridViewRow row in GridView1.Rows) { // Access the CheckBox CheckBox cb = (CheckBox)row.FindControl("UserSelector"); if (cb != null) cb.Checked = checkState; } } protected void CheckAll_Click(object sender, EventArgs e) { ToggleCheckState(true); } protected void UncheckAll_Click(object sender, EventArgs e) { ToggleCheckState(false); } Anyone can help me identify the mistake I did in my method? Thank you UserSelection GridView template:

• What is the "x = x || {}" technique in JavaScript - and how does it affect this IIFE?

  - by Micky Hulse

  First, a pseudo code example: ;(function(foo){ foo.init = function(baz) { ... } foo.other = function() { ... } return foo; }(window.FOO = window.FOO || {})); Called like so: FOO.init(); My question: What is the technical name/description of: window.FOO = window.FOO || {}? I understand what the code does... See below for my reason(s) for asking. Reason for asking: I'm calling the passed in global like so: ;(function(foo){ ... foo vs. FOO, anyone else potentially confused? ... }(window.FOO = window.FOO || {})); ... but I just don't like calling that lowercase "foo", considering that the global is called capitalized FOO... It just seems confusing. If I knew the technical name of this technique, I could say: ;(function(technicalname){ ... do something with technicalname, not to be confused with FOO ... }(window.FOO = window.FOO || {})); I've seen a recent (awesome) example where they called it "exports": ;(function(exports){ ... }(window.Lib = window.Lib || {})); I guess I'm just trying to standardize my coding conventions... I'd like to learn what the pros do and how they think (that's why I'm asking here)!

• PHP PDO changes remote host to local hostname

  - by Wade Urry

  I'm trying to connect to a remote mysql server using PDO. However, regardless of the hostname or ip address i supply in the dsn, when the script is run it always reverts the address to the hostname of the local server where the webserver is running. Google suggests this could be something to do with SELinux and apaches ability to connect to remote databases, however i have SELinux disabled. Distro: Ubuntu 11.04 x64 Apache version: 2.2.17 PHP Version: PHP 5.3.5-1ubuntu7.11 with Suhosin-Patch (cli) Edit: Added code as requested. Though i dont believe this is an issue with my coding as it works fine on the local server, but doesnt allow remote connection. public function db_connect($driver, $dbhost, $dbname, $user, $pass) { $dsn = $driver . ':host=' . $dbhost . ';dbname=' . $dbname; try { $this->DB = new PDO($dsn, $user, $pass); } catch (PDOException $err) { print 'Database Connection Failed: ' . $err->getMessage(); die(); } } $remote_db = new DB('mysql', 'remote_server.domain.tld', 'database_name', 'user_name', 'password'); This is the error message i am receiving. Database Connection Failed: SQLSTATE[28000] [1045] Access denied for user 'user_name'@'local_server.domain.tld' (using password: YES)

• Real time content editing html5

  - by Mark Lauzon

  So I've seen things like WordPress and FCKEditor, and basically a bunch of stuff that uses external code that I can't see or edit. Whenever I ask about editing and saving the content of a page in real time I just get referenced to an API or I get handed code that only changes the page until it's reloaded. What I want to know is how do I code it myself? I want to add real time content editing to a page without the use of someone else's code. I've checked out code for various forums and wikipedia and whatnot, and all of it references code I don't have access to. Is this a thing? Can I edit a page in real time? I thought of writing the edited text to a file on the server, and then when they click save, reading it back into the code to the section they were editing, but I don't know how to do that or if it's even possible. As a side note, I'm very new to html, but not new to coding. EDIT: The structure can be very much like Wikipedia, it doesn't have to be real time, it just has to work

• Getting a Script Error Every Time I Click a Link

  - by Flip4Life

  I have everything working perfectly on my site, but for some reason, I get an error message in console whenever I click a link anywhere on my site. The error has to do with this line of coding here: jQuery(function($){ $('.navbar a, .scroll a, .smoothscroll a').bind('click',function(event){ var $anchor = $(this); $('html, body').stop().animate({ scrollTop: $($anchor.attr('href')).offset().top }, 850,'easeInOutExpo'); event.preventDefault(); }); }); And the error I am getting is this: "SCRIPT5007: Unable to get value of the property 'top': object is null or undefined custom.min.js, line 6 character 197" The exact code it is highlighting is this part of the above code: $('html, body').stop().animate({ scrollTop: $($anchor.attr('href')).offset().top }, 850,'easeInOutExpo') All I know is that when I remove the above code, my scroll-to links stop working on pages such as these: http://www.northtownsremodeling.com/things-to-know.php You can see the popup error happen and stay in the console easily by going to a page with a filter like this: http://www.northtownsremodeling.com/bathroom/ And clicking one of the filter buttons. Ultimately, I am trying to make it so my scroll-to setting still works, but not have that error come up anymore. I made this script a long time ago, and I'm really confused as to what could be causing this error when everything is functioning perfectly otherwise? Thanks!

• OOP beginner: classB extends classA. classA already object. method in classB needed.. etc.

  - by Yvo

  Hey guys, I'm learning myself to go from function based PHP coding to OOP. And this is the situation: ClassA holds many basic tool methods (functions). it's __construct makes a DB connection. ClassB holds specific methods based on a certain activity (extract widgets). ClassB extends ClassA because it uses some of the basic tools in there e.g. a database call. In a php file I create a $a_class = new ClassA object (thus a new DB connection). Now I need a method in ClassB. I do $b_class = new ClassB; and call a method, which uses a method from it's parent:: ClassA. In this example, i'm having ClassA 'used' twice. Onces as object, and onces via a parent:: call, so ClassA creates another DB connection (or not?). So what is the best setup for this basic classes parent, child (extend) situation? I only want to make one connection of course? I don't like to forward the object to ClassB like this $b_class = new ClassB($a_object); or is that the best way? Thanks for thinking with me, and helping :d

• Php header('Location") error

  - by Umeed

  I'm having some difficulty with my php coding. I have 3 files, add.php, lib.php, and view.php I created a simple form, and when the user clicks submit, it should direct them to the view.php where it will display the database. Now I'm having a couple issues I can't seem to resolve. when the user clicks submit and the fields are blank or there is an error no entry should be made into the view page (or database)...however when I click submit a blank entry is made into the database. ALSO if i click "enter product" from the top menu bar anytime I click it, it causes a blank entry into the database. I can't figure out why that's happening. My next issue is with the header('Location') and my browser says: "Warning: Cannot modify header information - headers already sent by (output started at lib.php:13) in add.php on line 16" However if I click submit on my form it goes away. Here is the code for the pages: http://ideone.com/Vvz8x I truly apologize if the code is really messy. Any help / advice / solution is greatly appreciated thank you. And yes this was an assignment---it was due last week but since I couldn't finish it, it's not worth any marks anymore.

• C# Basic Multi-Threading Question: Call Method on Thread A from Thread B (Thread B started from Thre

  - by Nick

  What is the best way to accomplish this: The main thread (Thread A) creates two other threads (Thread B and Thread C). Threads B and C do heavy disk I/O and eventually need to pass in resources they created to Thread A to then call a method in an external DLL file which requires the thread that created it to be called correctly so only Thread A can call it. The only other time I ever used threads was in a Windows Forms application, and the invoke methods were just what I needed. This program does not use Windows Forms, and as such there are no Control.Invoke methods to use. I have noticed in my testing that if a variable is created in Thread A, I have no trouble accessing and modifying it from Thread B/C which seems very wrong to me. With Winforms, I was sure it threw errors for trying to access things created on other threads. I know it is unsafe to change things from multiple threads, but I really hoped .NET would forbid it altogether to ensure safe coding. Does .NET do this, and I am just missing the boat, or does it only do it with WinForm apps? Since it does seemingly allow this, do I do something like an OS would do, create a flag and monitor it from Thread A to see if it changes. If it does, then call the method. Doesnt the event handler essentially do this, so could an event be used somehow called on the main thread?

• Eclipc java,writting a program [closed]

  - by ghassar

  I have an important exercise for that i found in the internet please i need help in using eclipc java thanks i have to design, implement, test and document a Java program (a set of classes) for one of the following problem specifications: Problem 1 – Jubilee Estate Agency Property Management System A local Estate Agent would like a prototype system to keep track of properties that are offered for sale. The Estate Agent sells domestic and commercial properties. You will need to define classes that represent the Estate Agency System. You should design your system and the classes that you will need before starting coding. Your system must have a graphical user interface and be designed and developed using the object-oriented principles of the MVC architecture design pattern i.e. the user interface class must be separate from the other classes. The initial basic requirements for the system are as follows: • Include a list of domestic properties for sale that include details of: address, description, selling price, and number of rooms • Include a list of commercial properties for sale that include details of: address, description, selling price, and area in square metres • Enable the properties that are for sale to be viewed on the screen • Allow the customer to select one or more properties to be placed on a ‘viewing list’ so that the properties can be visited in person • Display on the screen the viewing list that shows the details of the properties chosen • Provide a basic search facility to find properties that are for sale in a particular price band and display the results • Enable a property to be marked as sold

• Can a pc with a 1.2 ghz dual core run VS 2013? [on hold]

  - by moo2

  Edit: This question is about a tool used for programming, Microsoft Visual Studio 2013. I already read the minimum requirements for VS 2013 before I posted or I wouldn't have asked the question. I searched on the web for an answer for a few hours before posting. Why should I go out and spend $400 on a laptop if I can spend less than $100 and use it to learn how to program? In the context of the question it is clear I was not asking for advice on what laptop to buy and it was also clear I was not asking for someone to walk me through the system requirements of VS 2013. This is a vast community and I was wondering if someone in this vast community would have experience in dealing with my question. In other words has anyone ever tried anything like it? If I had an old computer sitting around I would have tested it. At the moment all I have is a friend's Chromebook I'm borrowing. End Edit. I know the requirements for Microsoft Visual Studio 2013 state 1.6 ghz processor. I'm looking at getting a laptop for school and I found one that is old but cheap and would work for college. The Dell D430 I'm looking at getting has a 1.2ghz Core 2 Duo CPU, 80GB HD, 2GB RAM, and Windows 7 Home Premium. It's refurbished. I can get it for less than most phone's cost and from a Microsoft Authorized Refurbisher. I know it's not a skyrim rig but it's lightweight and can handle being a college laptop and doing word processing. Would Visual Studio 2013 run at all? If it is slower I'm not concerned. I just want to know if it would work and compile my assignments and run them? I'd be using this laptop for doing assignments and learning programming languages not for coding the next social media sensation.

• multiple webapps in tomcat -- what is the optimal architecture?

  - by rvdb

  I am maintaining a growing base of mainly Cocoon-2.1-based web applications [http://cocoon.apache.org/2.1/], deployed in a Tomcat servlet container [http://tomcat.apache.org/], and proxied with an Apache http server [http://httpd.apache.org/docs/2.2/]. I am conceptually struggling with the best way to deploy multiple web applications in Tomcat. Since I'm not a Java programmer and we don't have any sysadmin staff I have to figure out myself what is the most sensible way to do this. My setup has evolved through 2 scenarios and I'm considering a third for maximal separation of the distinct webapps. [1] 1 Tomcat instance, 1 Cocoon instance, multiple webapps -tomcat |_ webapps |_ webapp1 |_ webapp2 |_ webapp[n] |_ WEB-INF (with Cocoon libs) This was my first approach: just drop all web applications inside a single Cocoon webapps folder inside a single Tomcat container. This seemed to run fine, I did not encounter any memory issues. However, this poses a maintainability drawback, as some Cocoon components are subject to updates, which often affect the webapp coding. Hence, updating Cocoon becomes unwieldy: since all webapps share the same pool of Cocoon components, updating one of them would require the code in all web applications to be updated simultaneously. In order to isolate the web applications, I moved to the second scenario. [2] 1 Tomcat instance, each webapp in its dedicated Cocoon environment -tomcat |_ webapps |_ webapp1 | |_ WEB-INF (with Cocoon libs) |_ webapp1 | |_ WEB-INF (with Cocoon libs) |_ webapp[n] |_ WEB-INF (with Cocoon libs) This approach separates all webapps into their own Cocoon environment, run inside a single Tomcat container. In theory, this works fine: all webapps can be updated independently. However, this soon results in PermGenSpace errors. It seemed that I could manage the problem by increasing memory allocation for Tomcat, but I realise this isn't a structural solution, and that overloading a single Tomcat in this way is prone to future memory errors. This set me thinking about the third scenario. [3] multiple Tomcat instances, each with a single webapp in its dedicated Cocoon environment -tomcat |_ webapps |_ webapp1 |_ WEB-INF (with Cocoon libs) -tomcat |_ webapps |_ webapp2 |_ WEB-INF (with Cocoon libs) -tomcat |_ webapps |_ webapp[n] |_ WEB-INF (with Cocoon libs) I haven't tried this approach, but am thinking of the $CATALINA_BASE variable. A single Tomcat distribution can be multiply instanciated with different $CATALINA_BASE environments, each pointing to a Cocoon instance with its own webapp. I wonder whether such an approach could avoid the structural memory-related problems of approach [2], or will the same issues apply? On the other hand, this approach would complicate management of the Apache http frontend, as it will require the AJP connectors of the different Tomcat instances to be listening at different ports. Hence, Apache's worker configuration has to be updated and reloaded whenever a new webapp (in its own Tomcat instance) is added. And there seems no way to reload worker.properties without restarting the entire Apache http server. Is there perhaps another / more dynamic way of 'modularizing' multiple Tomcat-served webapps, or can one of these scenarios be refined? Any thoughts, suggestions, advice much appreciated. Ron

• How can I simulate blocking RTMP over port 80 on Windows?

  - by Christian Nunciato

  It seems like this should be so simple, but since this isn't my area of expertise, I'm having a hell of a time figuring out how to do it. Basically, I have a Flash app and I'm connecting to a Flash Media Server to stream some content. The URL I'm using to do this, for example, looks like this: rtmp://someserver.com/some/path/mp3:somefile Everything works -- but that's sort of the problem. When I'm trying to do is simulate my users attempting to play back my media under more restrictive conditions than the ones I have here (i.e., none) -- namely being stuck behind firewalls or proxy servers that block access to RTMP streams. Flash, according to Adobe, is equipped to handle proxy servers and firewalls automatically, like so (from the docs): When you do not specify a port number in an RTMP address, Flash will attempt to connect to port 1935. If it fails it will then try to connect to port 443; if that fails, it will try port 80. [And if that fails, it will attempt to connect via RTMPT (i.e., HTTP tunneling) on port 80.] So no coding is required to access ports 1935, 443, or port 80 if you do not specify a port in the RTMP address. The problem I'm having is setting up a reliable environment in which to test that this behavior actually happens. I'm on a Windows machine, for example, so with Windows Firewall, I can block certain ports and protocols (1935, 443), but I don't want to block port 80, because the final fallback protocol (RTMPT) is supposed to run on port 80, and Windows Firewall only gives me enough granularity (as far as I know, anyway) to block "all outbound TCP traffic to remote port 80" -- that is, I can't, apparently, block "all outbound RTMP traffic to port 80" while leaving RTMPT traffic to port 80 unaffected. My understanding thus far is that I'll probably need to set up a proxy server to do this. Is this correct? Or is there a simpler way (on Win 7, at least) to filter out RTMP to 1935, RTMP to 443, RTMP to 80, but still allow RTMPT to 80 (where all four hostnames are identical)? And if I do have to set up a proxy server, what's the simplest way to go on Windows? I've set up WinProxy, which seems a bit janky but apparently works -- but then what I can't figure out is how to tell Windows to force all TCP traffic (including RTMP, RTMPT and HTTO) through this proxy server so I can turn around and reject the requests for RTMP. Any help would be hugely appreciated. This isn't my realm of expertise and I've alreasdy spent more time on it than I probably should. :)

• Having troubles connectiong Magento to external Windows Database Server using Windows Azure

  - by Kevin H

  "I tried to make this easy to read through" I am using Ubuntu 12.04 LTS for Magento and installed these commands onto the system: sudo apt-get install apache2 sudo apt-get install php5 libapache2-mod-php5 sudo apt-get install php5-mysql sudo apt-get install php5-curl php5-mcrypt php5-gd php5-common sudo apt-get install php5-gd I used Windows Server 2008 R2 August 2012 for Mysql Server For a reference, I used http://www.windowsazure.com/en-us/manage/windows/common-tasks/install-mysql/ When the server was setup, I added an empty disk to it Then, I added endpoints 3306 Next I accessed the server remotely After that, I formatted the empty disk and was inserted as F: Next I downloaded Mysql from http://*.mysql.com version Windows (x86, 64-bit), MSI Installer 5.5.28 In the installation process, I used these settings: Typical Setup - Clicked Next, install, next Chose Detailed Configuration - Clicked next Chose Dedicated MySQL Server Machine - Clicked Next Chose Transactional Database Only - Clicked Next Chose the "F:" Drive - Clicked Next Chose Online Transactional Processing (OLTP) - Clicked Next For Networking Options, I checkmarked 'Enable TCP/IP Networking" 'Add firewall exception for this port' 'Enable Strict Mode' - Clicked Next Chose Standard Character Set - Clicked Next For Windows Options, I checkedmarked 'Install as Window Service" 'Launch the MySQL Server automatically' 'Include Bin Directory in Windows PATH - Clicked Next For Security Options, I checkmarked 'Modify Security Settings' and set root password - Clicked Next Finally clicked Execute and Finish These are the Firewall Setting that I set I clicked inbound rules Properties Scope Allow IP Address and used the internal Address for Magento Server Clicked Apply and exited Next, I opened up MySQL 5.x Command Line Client Entered Root Password Then entered these commands mysql create database magento; mysql Create user magentouser identified by 'password'; mysql Grant select, insert, create, alter, update, delete, lock tables on magento.* to magentouser mysql exit Finally, I opened up the Magento Downloader Magento validation has approved all PHP version is right.

PHP Extension curl is loaded PHP Extension dom is loaded PHP Extension gd is loaded PHP Extension hash is loaded PHP Extension iconv is loaded PHP Extension mcrypt is loaded PHP Extension pcre is loaded PHP Extension pdo is loaded PHP Extension pdo_mysql is loaded PHP Extension simplexml is loaded These are all installed on Magento Server For the Database Connection, I used: The Database server only has MySQL 5.5 Server installed on it Host - Internal IP address User Name - The User I created when setting up database Password - The Password I created when setting up database For the password, I did some research and found out that Magento only accepts alphanumeric, so I went and set it up again and used only alphanumeric for the User password Now, I am still getting Accessed denied for database Connection. Also, I have tryed to setup mysql on independant Linux Server but kept getting errors. When, I found the solution. Wouldn't work, so I decided to try Windows. These is the questions, I have been asking and researching to debug this issue Is it because I am using Linux for magento and Windows for Database. I have had no luck in finding a reason why this wouldn't work There must be something, I am missing I also researched the difference between linux sql databases and windows sql databases but have not come to conclusion, if installing Mysql on windows would make a difference in syntax and coding. I have spent a lot of time looking into this and need some help with direction on how to complete my project. Any type of help would be appreciated.

• T60 Screen/LCD gets black after some minutes with a highpitched sound rising and fading

  - by Edward De Leau

  Just now my T60 screen got "black" (so no display). On my second monitor: no problems so the vga output works. symptom: Screen blanks / no display but works on second monitor steps to reproduce: - boot - wait (it does not matter what you do you do not have to login or anything) - (now the monitor of the laptop slowly begins to make a ssssssssHHHHHHHHHHHHHHHHHWOEOEssssssss noice of about 10 seconds) - right after the sounds ends the monitor gets black times seem to be the same each time. software: installed no new software before/after, running zone alarm and antivirus. other: it does not feel hot in any place, there dont seem to be running processes with strange behaviour. warranty: out of warranty what was i doing: typing text on a website and doing some php coding in a text editor. Anyone any idea what I can do here other than buy a new laptop? / does it sound familiar to known cases? update: * exactly the same problem: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-Screen-Blackout/m-p/288772 and the second poster (garyj) here: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/Black-Screen-on-T60/m-p/235053#M48627 and here: "i have that same problem. i replaced the CCRL on mine and it works fine when the screen is not screwed in. once the frame of the LCD screen (metal portion) touches the metal on the laptop which holds the screen the screen goes black. If the metal is touching the screen when you boot up it boots up with it being very dimmly lit. " from http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-screen-problems/m-p/205047#M44995 (it seems replacing the lcd is no use, he tried it 3 times). same problem: http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60-black-screen/m-p/80604#M25914 Hmmm... not handy 3 or 4 months ago I ordered and installed a new fan. Now the LCD. Which does not seem the core isse but some electric issue so it seems replacing the LCD is not the thing todo here. I have the following question: If it is not the LCD that needs to be replaced (see other threads) which parts can I order to fix this? Has anyone got any information which could lead me to identify the issue? I have read replacing the "inverter" AND the "backlightning" would that make sense?

• Problems with MGCP proxy creation

  - by Popof

  Hi, I'm trying to bypass my ISP router with my FreeBSD server (I've an optical connection so I've a RJ45 used to connect the box to WAN) Internet and TV are working fine (Using igmpproxy to forward TV stream) but I've a problem with phone. ISP's box is connected to the server which gives it a LAN address. The problem is that when the box builds MGCP packets (and especially SDP ones) it uses its LAN address. So I've think of writing an UDP proxy to handle MGCP and SDP packets in order to replace LAN address with server WAN address and then forward packet to WAN. Before starting coding I've captured stream packets using my server as a bridge between WAN connection and the ISP's box. And, in order to see if my solution is viable, I've tried to send those packets to the box using nemesis. I tried to send a packet (found in capture) containing an endpoint audit: AUEP 1447 aaln/[email protected] MGCP 1.0 F: A In the wireshark capture the box replied: 200 1447 OK A: a:PCMU;PCMA;G726-16;G726-24;G726-32;G726-40;G.723.1-5.3;G.723.1-6.3;G729;TELEPHONE-EVENT, fmtp:"TELEPHONE-EVENT 0-15,144,149,159", p:10-30, b:4-40, e:on, t:00, s:on, v:L;M;G;D, m:sendonly;recvonly;sendrecv;inactive;confrnce;replcate;netwtest;netwloop, dq-gi But when I use nemesis, I got an ICMP error: Port unreachable (Type 3, Code 3). To build this packet, WAN source address of the capture is replaced with my server LAN address, using the mgcp-callagent port (2727) and the packet is sent to the LAN address of the box at mgcp-gateway port (2427). The command I use is nemesis udp -S 192.168.2.1 -D 192.168.2.2 -x 2727 -y 2427 -P packet_to_send. I also tried an UDP scan to the box on callagent and gateway port: PORT STATE SERVICE 2727/udp open|filtered unknown 2427/udp closed unknown I found those results a little bit strange because it should be the 2427 port opened, as it was in capture. Internet Protocol, Src: <ISP MGCP Server>, Dst: <My WAN Address> User Datagram Protocol, Src Port: mgcp-callagent (2727), Dst Port: mgcp-gateway (2427) Does someone has any idea about how having my box responding to my requests ? Thanks in advance and sorry for my english.

• Windows 7 & Virtual PC and Internet (gateway) problems on host PC

  - by Mufasa

  I upgraded to Windows 7 on a PC that is a few years old. The CPU was one revision away from having Hyper-V on it. So, I had to install Microsoft Virtual PC 2007 (v6.0.156.0) to run full XP instances instead of the seamless XP virtualization that is advertised so much. That's fine though; the 'older' version is useful since I use it to run different versions of the whole XP/IE stack for testing. (I'm a web developer.) ...And for the one 16-bit application we still use at the office for scheduling. * sigh * The virtual instances work fine, including networking. My issue is that after a reboot or coming out of sleep mode, my host Windows 7 won't connect to the Internet. It will connect to the local network fine. If I disable the "Virtual Machine Network Services" item (I'll call "VMNS" from here on) in the LAN Connection properties box, it starts working. But than the Virtual PC instances lose their network connectivity. If I re-enable VMNS again in the same instance, everything works (Internet on host and in the virtualized instances). But after the next reboot/sleep cycle this starts over. The route table gave me a clue though. When doing a cycle w/ VMNS enabled: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 On-link 10.0.3.51 20 0.0.0.0 0.0.0.0 10.0.10.10 10.0.3.51 276 ... After VMNS is disabled, the first route goes away. I assume that is for VMNS to intercept virtualized instance's network connections and forward them correctly? Just a guess though. More info: I checked my Firewall settings and Services (because I'm sort of a control nazi and turn off a lot) but couldn't find anything that made sense and if turned on changed anything. So it might be something there I'm missing, but I don't know what. My current hacked solution: So, I figured I'd mess with the routes myself to see if that helped, it did. If I run a route delete 0.0.0.0 on the universal (0.0.0.0) gateway routes, and add back in just the 2nd line with route add 0.0.0.0 mask 0.0.0.0 10.0.10.10--the one that points to my actual gateway (10.0.10.10)--then I don't have to mess with the disable/enable cycle of VMNS, and everything works. Running those two commands is faster then bringing up connection options and disabling and re-enabling VMNS, but I still don't want to have use that hack script every boot either. (Oh, and I also tried messing with hard-coding TCP/IP settings in my network adapter, including setting high metrics, etc., but that didn't help either.) Any suggestions on the right way to fix this?

• bluetooth connection using pybluez

  - by srj0408

  I am working on bluetooth not exactly on bluetooth stack-development but to use bluetooth in one of my project. I had done all that before using some of the py-bluez commands like hciconfig, hcitool scan , then simple-agents and using serial module inside python. But that was quite random. We were able to connect only one specific device based on its bluetooth address and there was no facility of reconnection once the devices are disconnected. Now i want to try out this stuff in a sequential manner like this (i am doing that all on a RPI and for at present on ubuntu 12.04.) i) Store some names in a file along with some other information with respect to that device. ii) Run a script to find out the device in locality with those names and if any one if found, report that. For this step, i had taken a reference from BTBook , made available from MIT. Below is the script for the same, but that script only search for the single name. from bluetooth import * target_name = "XT1033" target_address = None nearby_devices = discover_devices() for address in nearby_devices: if target_name == lookup_name( address ): target_address = address break if target_address is not None: print "found target bluetooth device with address ", target_address connect_socket(target_address); else: print "could not find target bluetooth device nearby" iii) Connect the device using client sock. But i dont have any device on which i can write a simple python script. My client can be any device that will be publishing data. Now i came through a script in the same book, that actually connect to a client requesting permission to connect to server. from bluetooth import * port = 1 server_sock=BluetoothSocket( RFCOMM ) server_sock.bind(("",port)) server_sock.listen(1) client_sock, client_info = server_sock.accept() print "Accepted connection from ", client_info data = client_sock.recv(1024) print "received [%s]" % data client_sock.close() server_sock.close() here client_sock, client_info = server_sock.accept() provide the client address and port requested to be connected. Can i pass address obtained from the earlier script to this, so that it connect server to the client? iv) Then if client get disconnected, re-connect(a simple polling can be used.) All this stuff can be done using bash and py-bluez functions but i want to do that in a sequential manner.I am not a master in python but i can do some small stuff. Can any one guide me for the same or can direct me to more usefull resource through which i can continue my coding part after finding the "X", "Y" named devices.
