  • No access to Samba shares

    - by koanhead
    I have three shared folders in my local home directory- that is to say, on my Ubuntu desktop's /home/me/. All were set up using "Sharing Options" in Nautilus' right-click menu. The standard "Music" and "Videos" folders are configured identically: the "Guest Access" box is checked, but the "Allow others to create and delete" is not. The third folder, called "shared", is configured to not allow Guest access but to allow others to modify files. I have not altered /etc/samba/smb.conf by hand, I have only used Sharing Options to create and modify these so-called "shares". My roommates have two Windows 7 computers and one Ubuntu Netbook Remix netbook. I have the aforementioned desktop machine and laptop running 10.04. None of these machines can access any of the shares. Attempts to access the Guest shares result in the message \\machine\directory is not accessible. The network name could not be found. This is the error message generated by a VM running Windows 2000. The other Windows machines generate a similar error. The Ubuntu laptop gives the error Unable to mount location: Failed to mount Windows share. Hurrah, once again, for informative error messages. That really helps a lot. When attempting to browse the folder called "shared" from the laptop, I'm confronted with a password dialog. This behavior is the same will all machines I've tried in the situation. On entering my username and password for the account to which the shares belong, the password dialog briefly disappears and is replaced with an identical dialog. No error message, useful or not, appears. When attempting to browse this folder with the VM, the outcome is the same except that the password dialog helpfully states "incorrect username or password". My assumption is that the username and password in question is that of the user which owns the shares. I have tried all other username and password combinations available in this context and the outcome is the same. I would like to be able to share files. Sharing them with Windows machines is a nice feature, or would be if it was available. Really I consider sharing files between two machines with the same version of the same operating system kind of a minimum condition for network usability. Samba last functioned reliably for me more than ten years ago. I have attempted to use it on and off since then with only intermittent success. Oh, and "Personal File Sharing" from the Preferences menu does not result in an entry in Places → Network → my-server. In fact, the old entry "MY-SERVER" goes away and is replaced by "koanhead's public files on my-server", which when I attempt to open it from the laptop gives a "DBus.Error.NoReply: Message did not receive a reply." I know I come here and gripe about Ubuntu a lot, but on the other hand I spend literally hours every day trying to fix things in Ubuntu. It's a good system which aspires to greatness, which is why things like this either Need to work; or Be adequately documented. Ideally both would be the case. Anyway, rant over. Hopefully someone will have some insight on this issue. Thanks all who bother to read this wall o'text for your time.

  • Building Enterprise Smartphone App &ndash; Part 1: Why Build Smart Phone Apps

    - by Tim Murphy
    This is part 1 in a series of post based on a talk I gave recently at the Chicago Information Technology Architects Group.  Feel free to leave feedback. Intro Most of us already carry smartphones. We play games on them. We keep up with what is going on with our friends and our favorite teams. We take pictures of our kids at their events. But the question is if that is all they are good for. Many companies have aspects of their business that lend themselves to being performed by mobile devices. Some of them lean toward larger device such as tablets, but many can be executed on smartphones. This and the following articles will discuss some of the possible applications of smartphone technology for businesses, the platforms that are available and the considerations you need to make when building them. I'll take a look at some specific scenarios and wrap up with a couple of capabilities that are just emerging that can be used in the future. Why Build Enterprise Smartphone Applications So what are some of the ways that you can leverage smartphone technology to gain efficiency in your business or a clients business. There are a few major areas that I have seen mobile platforms being an advantage to. Your mobile sales force is a key candidate for leveraging smartphone apps.  They can visit clients in their retail location and place orders on site. It is a more personal approach which can gain you customer loyalty.  A sales person may also gather information about the way a client does business or who their target market is. This allows them you to focus marketing information or build customized support for your customer. You may also have need to track physical inventory in a store. This is something that has historically been done with laser scanners, but with the camera capabilities in today's phones and tablets it is possible to use more general multi-purpose devices.  This can save costs on both hardware and telecommunication contracts. Delivery verification is another area that historically has been the domain of specialized devices but can now be accomplished with smartphones.  This also reduces costs because it is also used for communicating with the driver and other operations.  Add to that the navigation capability of smartphones and you can see how the return on investment increases. Executives are always on the go. They spend most of their time in meetings and yet they need access to decision making information at their finger tips. With a smartphone app they can get alerts when major sales are closed or critical accounting process are completed that may need their attention. They can also answer questions by instantly pulling up BI reports. I have often heard operations support people say that they need things like VPN and RDP from their phones. If they can also have notifications of outages or critical support requests they can be react to situations without needing to be tied to their desks. These are all valid reasons to need smartphone applications.  In the next installment I will discuss platforms and features. del.icio.us Tags: Smartphones,Enterprise Smartphone Apps,Architecture

  • The HTTP request was forbidden with client authentication scheme 'Anonymous'

    - by dudia
    I am trying to configure a WCF server\client to work with SSL I get the following exception: The HTTP request was forbidden with client authentication scheme 'Anonymous' I have a self hosted WCF server. I have run hhtpcfg both my client and server certificates are stored under Personal and Trusted People on the Local Machine Here is the server code: binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate; binding.Security.Mode = WebHttpSecurityMode.Transport; _host.Credentials.ClientCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.PeerOrChainTrust; _host.Credentials.ClientCertificate.Authentication.RevocationMode = X509RevocationMode.NoCheck; _host.Credentials.ClientCertificate.Authentication.TrustedStoreLocation = StoreLocation.LocalMachine; _host.Credentials.ServiceCertificate.SetCertificate("cn=ServerSide", StoreLocation.LocalMachine, StoreName.My); Client Code: binding.Security.Mode = WebHttpSecurityMode.Transport; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate; WebChannelFactory<ITestClientForServer> cf = new WebChannelFactory<ITestClientForServer>(binding, url2Bind); cf.Credentials.ClientCertificate.SetCertificate("cn=ClientSide", StoreLocation.LocalMachine, StoreName.My); ServicePointManager.ServerCertificateValidationCallback += RemoteCertificateValidate; Looking at web_tracelog.svclog and trace.log reveals that the server cannot autheticate the client certificate My certificate are not signed by an Authorized CA but this is why I added them to the Trusted People.... What Am I missing? What am I missing?

  • Exception on SslStream.AuthenticateAsClient (The message was badly formatted)

    - by Noms
    I have got wierd problem going on. I am trying to connect to Apple server via TCP/SSL. I am using a Client certificate provided by Apple for push notifications. I installed the certificate on my server (Win2k3) in both Local Trusted Root certificates and Local Personal Certificates folder. Now I have a class library that deals with that connection, when i call this class library from a console application running from the server it works absolutely fine, but when i call that class library from an asp.net page or asmx web service I get the following exception. A call to SSPI failed, see inner exception. The message received was unexpected or badly formatted. This is my code: X509Certificate cert = new X509Certificate(certificateLocation, certificatePassword); X509CertificateCollection certCollection = new X509CertificateCollection(new X509Certificate[1] { cert }); // OPEN the new SSL Stream SslStream ssl = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null); ssl.AuthenticateAsClient(ipAddress, certCollection, SslProtocols.Default, false); ssl.AuthenticateAsClient is where the error gets thrown. This is driving me nuts. If the console application can connect fine, there must be some problem with asp.net network layer security that is failing the authentication... not sure, perhaps need to add something or some sort of security policy in the web.config. Also just to point out that i can connect fine on my local development machine both with console and website. Anyone has got any ideas?

  • Why can't I resolve ambiguity with Android.OS.Environment?

    - by C. Lang
    I'm trying to use Environment.(...) in my Xamarin app. It complains that "Environment is an ambiguous reference between System.Environment and Android.OS.Environment" I can fix it by using the fully qualified name System.Environment.(...) but not with Android.OS.Environment.(...). For example: // Obviously ambiguous with error above using System; using Android.OS; // ... // OnCreate uses Bundle also in Android.OS //... string path = Environment.GetFolderPath(Environment.SpecialFolder.Personal); // Can be fixed by prefixing Environment with "System." But I can't fix it with any variation of possibilities using Android.OS including removing it and explicitly using it. The auto-complete box only shows the Activities and "Resource" and not any of the classes. // Solution to be able to use Android's Environment using Android.OS; // same as above Java.IO.File storageDir = Environment.ExternalStorageDirectory; // Defaults to Android.OS but can still use "System.Environment.(...) // Of course not with this example, but with the one above; yes. // Why doesn't it work both ways? If I remove the using statement and // try to use Android.OS.Environment.(...) it complains // 'OS type or namespace doesn't not exist' The reason is prefixing with Android. is referring to MyAppName.App.Android. Why is that and is there a way to directly access Android.OS.(...)? I've tried Mono.Android.OS.(...).

  • What are some good/reputable/widely-used libraries written in VB.NET?

    - by Dan Tao
    Generally speaking, when VB.NET and C# are compared, there is a lot of strong support for C#, accompanied by some bashing of VB.NET until a respected developer comes along and acts as The Voice Of Reason, pointing out that while VB prior to VB.NET had its fair share of issues, VB.NET is really a very strong, fully OOP language that is, feature-wise, right about on par with C# (with the exception of certain things like a full-bodied lamba syntax [pre-VB10] or the yield keyword, as many C# faithfuls are quick to point out). I myself, having written plenty of code in both VB.NET and C#, fall squarely in the "I prefer C#, but don't consider VB.NET any less of a language" camp. However, one thing I have noticed is that when it comes to respected and/or widely-used libraries for .NET, everyting is written in C#. Or at least that's been my impression. This strikes me as a little strange because, aside from the abovementioned sprinkling of nice features (in particular the yield keyword), I tend to view the VB.NET/C# divide as primarily a matter of personal taste. Obviously, plenty of developers prefer C#. But I personally know some developers (good ones) who prefer VB.NET, which would lead me to suspect that surely some libraries (good ones) would be written in VB.NET. They must be out there, and I just haven't found them. What are some good libraries that've been written in VB.NET? The best would be open source, as that would allow interested developers to take a look at some good VB.NET code and see how effective the language can be when used properly. But I'd be interested to know about any libraries at all, particularly reputable ones.

  • Powershell Transcript is empty when running script from SQL Agent Job in 2005 SQL Server

    - by Greg Bray
    I have a complex Powershell script that gets run as part of a SQL 2005 Server Agent Job. The script works fine, but it uses the "Start-Transcript $strLogfile -Append" command to log all of it's actions to a transcript file. The problem is that the transcript is always empty. It adds the header and footer to indicate that the transcript is starting and stopping, but it doesn't actually log anything. Example: ********************** Windows PowerShell Transcript Start Start time: 20100304173001 Username : xxxxxxxxxxxx\SYSTEM Machine : xxxxx-xxx (Microsoft Windows NT 5.2.3790 Service Pack 2) ********************** ********************** Windows PowerShell Transcript End End time: 20100304173118 ********************** When I execute the script from a command prompt or start - run everything works just fine. Here is the command used to run the script (same command used in the Operating system CmdExec step of the SQL Agent Job) powershell.exe -File "c:\temp\Backup\backup script.ps1" I first thought it must have something to do with the script running under the System account (default SQL Agent account), but even when I tried changing the SQL Agent to run under my own personal account it still created a blank transcript. Is there any way to get PowerShell Transcripts to work when executing them as part of a 2005 SQL Server Agent Job?

  • Model validation with enumerable properties in Asp.net MVC2 RTM

    - by Robert Koritnik
    I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

  • Send Email via Google Apps in C#

    - by NateReid
    Hello, I am trying to send a basic email through Google Apps/Gmail using C# (System.Net.Mail/Framework 4) and I am having trouble doing so. I am receiving the following exception: "The operation has timed out." My code is below: //Create the mail message MailMessage mail = new MailMessage(); //Set the addresses mail.From = new MailAddress("[email protected]", "My Name"); mail.To.Add(Email); //Set the subject and bodycontent mail.Subject = "Email Testing"; mail.Body = "This is the body of the email"; //Send the message using the SmtpClient SmtpClient smtp = new SmtpClient(); smtp.EnableSsl = true; smtp.Send(mail); My web.config has the following settings: <smtp from="[email protected]" deliveryMethod="Network"> <network host="smtp.gmail.com" password="password" port="587" userName="[email protected]" /> </smtp> During my troubleshooting I have tried: Using my personal gmail address as well as another from a domain hosted through Google Apps. Using ports 25, 465, and 587 Hard coding the config settings in the c# code instead of using the web.config Sending and telneting from multiple network locations to ensure the firewall/ISP was not blocking it Ensured that POP was enabled in the GMail settings (according to Google this should turn on the ability to send using SMTP) Changing the send from and replyTo address to ensure they match the account (apparently a GMail necessity). I am able to send and receive email fine through the GMail interface for both of my email accounts. I have also tried the settings and solutions offered in Question # 757987 to no avail. Any suggestions would be greatly appreciated. Thanks all.

  • Can aptitude for learning Programming paradigms be influenced by culture or native language's gramma

    - by DVK
    It is well known that different people have different aptitudes regarding various programming paradigms (e.g. some people have trouble learning non-procedural, especially functional languages. Some people have trouble understanding pointers - see Joel Spolsky's blog for musings on that. Some people have trouble grasping recursion). I was recently reading about a study that looked at how the grammar of someone's native language affected their speed of learning math. Can't find that article now but a quick googling found this reference. That led me to wondering whether someone's native culture or first language might affect their aptitude towards various programming paradigms. I'm more curious about positive influences - e.g. some trait that make it easier/faster for someone to learn a particular paradigm, for example native language grammar being very recursion-oriented. To be clear, I'm looking for how culture/language grammare may affect the difference between aptitude of the same person towards various paradigms as opposed to how it affects overall aptitude towards programming between different persons. Important: the only answers I'm interested in are either references to scientific studies, or personal observations from someone intimately familiar with a particular culture/language, including from their own experience. E.g. I'm not interested in your opinion of how Chinese being your first language affects anything unless you speak Chinese or worked with extremely large set of Chinese-native programmers extensively. I'm OK with your guesstimates not based on scientific studies, but please be sure to supply your reasoning about plausible causes of your observation. I'm not interested in culture-bashing (any such commends will be deleted or flagged for deletion). I'm also not particularly interested in culture-building - we all know Linus is from Finland and Tetris was written in Russia and Larry Wall is an American. Any culture/nation can produce a brilliant mind in any discipline. I'm interested in averages.

  • Schliemann's method of programming language learning

    - by DVK
    Background: 19th-century German archeologist Heinrich Schliemann was of course famous for his successful quest to find and excavate the city of Troy (an actual archeological site for the Troy of Homer's Iliad). However, he is just as famous for being an astonishing learner of languages - within the space of two years, he taught himself fluent Dutch, English, French, Spanish, Italian and Portuguese, and later went on to learn seven more, including both modern and ancient Greek. One of the methods he famously used was comparison of a known text, e.g. take a book in a language one is fluent in, take a good translation of a book in a language you wish to learn, and go over them in parallel. (various sources cited the book used by Schliemann to be the Bible, or, as the link above states, a novel). Now, for the actual question. Has anyone used (or heard of) an equivalent of Schliemann's method for learning a new programming language? E.g. instead of basing the leaning on references and tutorials, take a somewhat comprehensive set of programs known to have high-quality code in both languages implementing similar/identical algorithms and learn by comparing them? I'm curious about either personal experiences of applying such an approach, or references to something published, or existance of codebases which could be used for such an approach? What got me thinking about the idea was Project Euler and some code snippets I saw on SO, in C++, Perl and Lisp.

  • What's a good way to teach my son to program Java

    - by Software Monkey
    OK, so I've read through various posts about teaching beginner's to program, and there were some helpful things I will look at more closely. But what I want to know is whether there are any effective tools out there to teach a kid Java specifically? I want to teach him Java specifically because (a) with my strong background in C I feel that's too complex, (b) Java is the other language I know extremely well and therefore I can assist meaningfully without needing to teach myself a new but (to me) useless language, and (c) I feel that managed languages are the future, and lastly (d) Java is one of the simplest of all the languages I know well (aside from basic). I learned in basic, and I am open to teaching that first, but I am unaware of a decent free basic shell for Windows (though I haven't really searched, yet since it's not my first choice), and would anyway want to progress quickly to Java. My son is 8, so that's a couple of years earlier than I started - but he has expressed an interest in learning to program (possibly because I work from home a lot and he sees me programming all the time). If no-one can suggest a tool designed for this purpose, I will probably start him off with text/console based apps to teach the basics, and then progress to GUI building. Oh, one last thing, I am not a fan of IDE's (old school text editor type), so I would not be put off at all by a system that has him typing real code, and would likely prefer that to a toy drag/drop system. EDIT: Just to clarify; I really am specifically after ways to teach him Java; there are already a good many posts with good answers for other language alternatives - but that's not what I am looking for here. EDIT: What about Java frameworks for 2D video games - can anyone recommend any of them from personal experience? I like the idea of him starting with the mechanics in place (main game loop, scoring, etc) and adding the specifics for a game of his own imagining - that's what I did, though for me it was basic on a Commodore VIC-20 and a Sinclair ZX-81.

  • Simple iPhone drawing app with Quartz 2D

    - by Mr guy 4
    I am making a simple iPhone drawing program as a personal side-project. I capture touches event in a subclassed UIView and render the actual stuff to a seperate CGLayer. After each render, I call [self setNeedsLayout] and in the drawRect: method I draw the CGLayer to the screen context. This all works great and performs decently for drawing rectangles. However, I just want a simple "freehand" mode like a lot of other iPhone applications have. The way I thought to do this was to create a CGMutablePath, and simply: CGMutablePathRef path; -(void)touchBegan { path = CGMutablePathCreate(); } -(void)touchMoved { CGPathMoveToPoint(path,NULL,x,y); CGPathAddLineToPoint(path,NULL,x,y); } -(void)drawRect:(CGContextRef)context { CGContextBeginPath(context); CGContextAddPath(context,path); CGContextStrokePath(context); } However, after drawing for more than 1 second, performance degrades miserably. I would just draw each line into the off-screen CGLayer, if it were not for variable opacity! The less-than-100% opacity causes dots to be left on the screen connecting the lines. I have looked at CGContextSetBlendingMode() but alas I cannot find an answer. Can anyone point me in the right direction? Other iPhone apps are able to do this with very good efficiency.

  • Client Certificate installed in IE8 on Windows 7 doesn't work - 403.7

    - by mlauter
    We have configured IIS 6 to accept client certificates and have installed the certificate services on our server. When we go to http://[our site]/CertSrv and request a Web Browser Certificate (client certificate) from IE7/8 on Windows XP and Vista and Windows 7, then issue the cert on the server certificate authority manager, all combinations of the client/OS seem to install the client certificate properly in the personal certificate store. When we visit our test application that requires client certificates, all IE versions installed in Windows XP propmt for the client certificate and then properly display the page. Uhfortunately, all IE versions installed on Vista and Windows 7 do not prompt for the cert, nor do they automatically send the cert. It's like IE on these operating systems is unaware of the client certificate and it doesn't prompt for it, nor does it send it to the site. Since everything works as expected, at least on the XP configurations, we assume that IIS6 is correctly configured. It's been 8 hours with two of us trying to figure this out and we're ready to throw a laptop through a window and "the google" has let us down. Thanks for anyone who can help. Mark

  • Workflow for academic research projects, one-step builds, and the Joel Test

    - by Steve
    Working alone on academic research sometimes breeds bad habits. With no one else reading my code, I would write a lot of throw-away code, and I would lose track of intermediate results which, weeks or months later, I wish I had retained. My recent attempts to make my personal workflow conform to the Joel Test raised interesting questions. Academic research has inherently different goals than industrial software development, and therefore some aspects of the Joel Test become less valid. Nevertheless, I find these steps to be still valuable for academic research: Do you use source control? Can you make a build in one step? Do you have an up-to-date schedule? Do you have a spec? Of particular use is the one-step build. I find myself more organized now that I have implemented the following "one-step build": In other words, I have a single script, build.py, that accepts Python code, data, and TeX as inputs. The outputs are results, figures, and a paper with all the results filled in. (Yes, I know "build" is probably not accurate in this context, but you get the idea.) By consolidating many small steps into one, I am not backtracking as much as I used to. ...but I'm sure there is still room for improvement. Question: For research projects, which steps of the Joel Test do you still value? Do you have a one-step build? If so, what does yours consist of, i.e., what inputs does it accept, and what output does it generate?

  • Convert ISO-8859-1 to UTF-8

    - by tau
    I have several documents I need to convert from ISO-8859-1 to UTF-8 (without the BOM of course). This is the issue though. I have so many of these documents (it is actually a mix of documents, some UTF-8 and some ISO-8859-1) that I need an automated way of converting them. Unfortunately I only have ActivePerl installed and don't know much about encoding in that language. I may be able to install PHP, but I am not sure as this is not my personal computer. Just so you know, I use Scite or Notepad++, but both do not convert correctly. For example, if I open a document in Czech that contains the character "ž" and go to the "Convert to UTF-8" option in Notepad++, it incorrectly converts it to an unreadable character. There is a way I CAN convert them, but it is tedious. If I open the document with the special characters and copy the document to Windows clipboard, then paste it into a UTF-8 document and save it, it is okay. This is too tedious (opening every file and copying/pasting into a new document) for the amount of documents I have. Any ideas? Thanks!!!

  • Accessing Yahoo realtime stock quotes

    - by DVK
    There's a fairly easy way of retrieving 15-minute delayed quotes off of Yahoo! Finance web site ("quotes.csv" API). However, so far I was unable to find any info on how to access real-time quotes. The hang-ups with real-time quotes are: Only available to logged-in user No API Non-obvious how to scrape the info - I'm somewhat convinced they are placed on the page by some weird Ajax call. So I was wondering if anyone had managed to develop a publically available solution to retrieve real-time quotes for a stock from Yahoo! Finance. Notes: Implementation language/framework need is flexible but Perl or Excel is highly preferred. Assume that security is not an issue - I'm willing to supply yahoo userid and pasword, even in cleartext. I'm not 100% hung up on Yahoo - they are merely the only provider of free realtime stock quotes I'm familiar with. if the same thing can be done with Google Finance, I'd be just as happy. This is for a personal project, so scalability/fault tolerance/etc... are not important. I'm looking for a "do the whole retrieval" library ideally, but if I'm pointed to partial solutions (e.g. how to retrieve info from Yahoo's user-logged-in pages; how to scrape realtime quotes from Yahoo's page) I can fill in the blanks. I saw Finance::YahooQuote but it does not seem to allow you to supply log-in information and appears to use the lagging quotes.csv API Thanks!

  • Storing info in a PostgreSQl database issue

    - by MrEnder
    Ok I am making a registry for my website. First page asks for some personal info if($error==false) { $query = pg_query("INSERT INTO chatterlogins(firstName, lastName, gender, password, ageMonth, ageDay, ageYear, email, createDate) VALUES('$firstNameSignup', '$lastNameSignup', '$genderSignup', md5('$passwordSignup'), $monthSignup, $daySignup, $yearSignup, '$emailSignup', now());"); $query = pg_query("INSERT INTO chatterprofileinfo(email, lastLogin) VALUES('$emailSignup', now());"); $userNameSet = $emailSignup; $_SESSION['$userNameSet'] = $userNameSet; header('Location: signup_step2.php'.$rdruri); } The first query works.

  • How can one detect if a server/script is accessing their site through cURL/file_get_contents()? (excluding user-agents and IP addresses)

    - by navnav
    I've come across a question where a user is having difficulties accessing an image through a script (using cURL/file_get_contents()): How to save an image from url using PHP? The image link seems to return a 403 error when using file_get_contents() to request it. But in cURL, a more detailed error is returned: You were denied access to the system. Turn off the engine or Surf Proxy, Fake IP if you really want to access. Proxy or not accepted from any Web tools Intrusion Prevention System. Binh Minh Online Data Services @ 2008 - 2012 I also failed to access the same image after fiddling around with a cURL request myself. I tried changing the user-agent to my exact browsers user-agent which can successfully access the image. I've also tried the script on my personal local server, which (obviously) uses the same IP address as my browser... So as far as I know, user-agents and IP addresses are out of the situation. How else can someone detect a script performing a request? BTW, this is not for anything crazy. I'm just curious xD

  • iPhone Developer Program registration for UK trading partnership

    - by CMLloyd
    I have been looking into this for a long time and have found no definitive answer. I can't be the only person to have faced this problem and am wondering how you guys proceeded in similar cases. I'm part of a partnership, based in the UK, trading as, lets say, "ABCD iPhone Apps" (legally, a perfectly legitimate way of doing business). I've now developed an iPhone App and I want our company name ("ABCD iPhone Apps") to appear as the seller in the App Store. This way, any future Apps that we develop can all get released under the "ABCD iPhone Apps" aegis too. Given that we aren't an incorporated company (and probably never will be), is it possible for us to enroll in the iPhone Developer Program as a company? Or is there another solution? (Note: I do also have an Individual account but that is for personal projects and is in no way connected to the partnership, and shall remain that way) EDIT: I've just spoken to a guy at ADC UK and he tells me there is no other solution. For a company to be approved on the Developer Program, Apple needs to see a copy of the company's Certificate of Incorporation during the registration process, otherwise no approval.

  • How to handle correctly HTTP Digest Authentication on iPhone

    - by Fabiano Francesconi
    Hello guys. I'm trying to upload a file onto my personal server. I've written a small php page that works flawlessy so far. The little weird thing is the fact that I generate all the body of the HTTP message I'm going to send (let's say that amounts to ~4 mb) and then I send the request to my server. The server, then, asks for an HTTP challenge and my delegate connection:didReceiveAuthenticationChallenge:challenge replies to the server with the proper credentials and the data. But, what's happened? The data has been sent twice! In fact I've noticed that when I added the progressbar.. the apps sends the data (4mb), the server asks for authentication, the apps re-sends the data with the authentication (another 4mb). So, at the end, I've sent 8mb. That's wrong. I started googling and searching for a solution but I can't figure out how to fix this. The case scenarios are two (my guess): Share the realm for the whole session (a minimal HTTP request, then challenge, then data) Use the synchronized way to perform an HTTP connection (things that I do not want to do since it seems an ugly way to handle this kind of stuff to me) Thank you

  • Annoying Twisted Python problem

    - by Kalmi
    I'm trying to answer the following question out of personal interest: What is the fastest way to send 100,000 HTTP requests in Python? And this is what I have came up so far, but I'm experiencing something very stange. When installSignalHandlers is True, it just hangs. I can see that the DelayedCall instances are in reactor._newTimedCalls, but processResponse never gets called. When installSignalHandlers is False, it throws an error and works. from twisted.internet import reactor from twisted.web.client import Agent from threading import Semaphore, Thread import time concurrent = 100 s = Semaphore(concurrent) reactor.suggestThreadPoolSize(concurrent) t=Thread( target=reactor.run, kwargs={'installSignalHandlers':True}) t.daemon=True t.start() agent = Agent(reactor) def processResponse(response,url): print response.code, url s.release() def processError(response,url): print "error", url s.release() def addTask(url): req = agent.request('HEAD', url) req.addCallback(processResponse, url) req.addErrback(processError, url) for url in open('urllist.txt'): addTask(url.strip()) s.acquire() while s._Semaphore__value!=concurrent: time.sleep(0.1) reactor.stop() And here is the error that it throws when installSignalHandlers is True: (Note: This is the expected behaviour! The question is why it doesn't work when installSignalHandlers is False.) Traceback (most recent call last): File "/usr/lib/python2.6/dist-packages/twisted/internet/base.py", line 396, in fireEvent DeferredList(beforeResults).addCallback(self._continueFiring) File "/usr/lib/python2.6/dist-packages/twisted/internet/defer.py", line 224, in addCallback callbackKeywords=kw) File "/usr/lib/python2.6/dist-packages/twisted/internet/defer.py", line 213, in addCallbacks self._runCallbacks() File "/usr/lib/python2.6/dist-packages/twisted/internet/defer.py", line 371, in _runCallbacks self.result = callback(self.result, *args, **kw) --- <exception caught here> --- File "/usr/lib/python2.6/dist-packages/twisted/internet/base.py", line 409, in _continueFiring callable(*args, **kwargs) File "/usr/lib/python2.6/dist-packages/twisted/internet/base.py", line 1165, in _reallyStartRunning self._handleSignals() File "/usr/lib/python2.6/dist-packages/twisted/internet/base.py", line 1105, in _handleSignals signal.signal(signal.SIGINT, self.sigInt) exceptions.ValueError: signal only works in main thread What am I doing wrong and what is the right way? I'm new to twisted.

  • Model validation with enumerations

    - by Robert Koritnik
    I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

  • SCM for Xcode?

    - by Gregor
    I am developing an application for the Mac as a small team (me + another person) effort. We are located in different cities, and have started to see the need for solid source control management. None of us have any experience with this, and both of us are relatively new to Cocoa/Obj-C/Xcode (but do have C knowledge). Does anyone have any recommendations as to which SCM system to choose? I understand that a lot of people are using Subversion, which is also supported in Xcode 3.1. Does anyone have experience with using Subversion through Xcode? Or is it a better option to chose a stand alone GUI alternative, such as Versions? Grateful for any input on this. Gregor Tomasevic, Sweden Update/personal experiences: Since this post, we have tried Versions and Cornerstone (both of which are SVN GUI-clients), as well as Xcodes built-in support for SVN. We were not particularly pleased with Versions, which seemed to have some problems with committing unversioned files/build files. The built-in SVN support in Xcode works quite well, although it probably has limitations that we have still not run into. Cornerstone is both simple to use and powerful, and does not seem to suffer from the problems we encountered with Versions. So far, we have just tried committing, updating repo, checking out latest/previous versions of our files and worked some with file comparison. It might be a whole different ball game once you start working extensively with branching, an area which we have been told both these GUI clients might have some weaknesses in. For what it's worth (and with only days of evaluation) Cornerstone seems to be a somewhat better alternative, although for simpler SCM, Xcode works well too. Thanks for all the comments.

  • What are some strategies for maintaining a common database schema with a team of developers and no D

    - by Mahmoud Abdelkader
    I'm curious about how others have approached the problem of maintaining and synchronizing database changes across many (10+) developers without a DBA? What I mean, basically, is that if someone wants to make a change to the database, what are some strategies to doing that? (i.e. I've created a 'Car' model and now I want to apply the appropriate DDL to the database, etc..) We're primarily a Python shop and our ORM is SQLAlchemy. Previously, we had written our models in such a way to create the models using our ORM, but we recently ditched this because: We couldn't track changes using the ORM The state of the ORM wasn't in sync with the database (e.g. lots of differences primarily related to indexes and unique constraints) There was no way to audit database changes unless the developer documented the database change via email to the team. Our solution to this problem was to basically have a "gatekeeper" individual who checks every change into the database and applies all accepted database changes to an accepted_db_changes.sql file, whereby the developers who need to make any database changes put their requests into a proposed_db_changes.sql file. We check this file in, and, when it's updated, we all apply the change to our personal database on our development machine. We don't create indexes or constraints on the models, they are applied explicitly on the database. I would like to know what are some strategies to maintain database schemas and if ours is seems reasonable. Thanks!
