  • Sharing files with Android devices (How do I mount an HP Touchpad, Cyanogen Mod 9?)

    - by C.Werthschulte
    I've recently installed Cyanogen Mod 9 on my HP Touchpad tablet, but I'm encountering problems when trying to access it from my Ubuntu laptop (Ubuntu 11.10, Gnome-Shell, Nautilus). I've first tried accessing it via PTP as suggested here. Ubuntu will recognize the Touchpad as a digicam and only grant me access to two directories: "DCIM" and "Pictures". I then tried accessing the tablet via MTP using this post on OMGUbuntu!. Ubuntu will connect to the tablet, but only grant me access to a folder named "Playlists". I'm a bit clueless as to what I'm doing wrong and would very much appreciate any help or hints. Many thanks!

  • Site inaccessible by some people, fine for others [on hold]

    - by Paul Howell
    A couple of days ago my website www.howellphoto.com (hosted by one.com, wordpress site) started loading really slowly, and I have been unable to access any pages linked from the homepage. Several of my friends have found the same issue, yet many are able to access the site without problem. Live support at one.com have not been all that much help, requesting the ip addresses of a few people who cannot access the site, and saying it could be a firewall issue. Wordpress support (my site was created in prophotoblogs) have been better and have updated all plugins, etc, but can see no issue from their end. My main issue is that even if there was a local fix that I could do on my computer, this would not help wih any potential customers visiting my site for information! This is driving me crazy!!! Any help will be legendary! Cheers, Paul

  • Auto mount USB drive with permissions for all users

    - by oneaustin
    I have an Ubuntu 14.04 based Media Center and I store the media files on a USB HDD. I add files to drive directly on a Mac so I have it formatted as FAT32. The problem is that after reconnecting the drive to the Ubuntu, it mounts at /media/user/drivename and only the root user is allowed access. I need several applications to have full access to this drive. I can change file permissions in the terminal but it doesn't change because of the /media/user location. I am able to manually sudo mount /dev/sdc1 /media/drivename & sudo chmod 777 /media/drivename but the mount point changes each time. Is there a way to make this drive always mount where root and other applications have access?

  • Connecting to a Windows SVN server from Ubuntu

    - by skytreader
    I need to access an SVN repo hosted on a Windows machine from Ubuntu. However, even if I supply the proper credentials, it denies me access, apparently because Windows does not allow Linux connections (as they told me); sure enough, I got in when I tried to checkout from my XP partition. While I have my box dual-booted, it is inconvenient to switch just for SVN. So, does anyone know how I can access that SVN repo from Ubuntu? I've tried installing TortoiseSVN and Windows Subversion under Wine but I can't even get them to run; they were asking for some DLLs that I don't know how to supply. I've thought of installing a virtual XP just for SVN but I consider that too extreme and I'd be glad if anyone can advise a simpler workaround.

  • Encrypted Ubuntu Partition HELP!

    - by user207984
    I had Zorin 7 Encrypted. I accidentally deleted important GRUB data trying to make more room in the boot folder i think? So the computer would no longer boot up. Anyways, I installed a second Linux OS on the same laptop, but I am unable to access all of my important information that is still on the encrypted partition. When i go to mount it to access everything, it asks for the encryption password... however, it tells me the password is incorrect, which I know 100% that it is the correct password. Someone please help me! Inform me how I can access this encrypted partition or restore the data so that I can boot the computer in Zorin 7 again.

  • Do any database "styles" use discrete files for their tables?

    - by Brad
    I've been talking to some people at work who believe some versions of a database store their data in discrete tables. That is to say you might open up a folder and see one file for each table in the database then several other supporting files. They do not have a lot of experience with databases but I have only been working with them for a little over a half year so I am not a canonical source of info either. I've been touting the benefits of SQL Server over Access (and before this, Access over Excel. Great strides have been made :) ). But, other people were of the impression that the/one of the the benefit(s) of using SQL Server over Access was that all the data was not consolidated down into one file. Yet, SQL Server packs everything into a single .mdf file (plus the log file). My question is, is there an RDBMS which holds it's data in multiple discrete files instead of one master file? And if the answer is yes, why do it one way over the other?

  • How can I pull data from PeopleSoft on demand?

    - by trpt4him
    I work in IT at a university and I'm working with about 5 different departments to develop a new process for students to apply to a specific school within the university (not the university as a whole). We're using a web-based college application vendor and adding the applicant questions for the school itself to the main university application. Currently the main application feeds into PeopleSoft. The IT staff here is building a new table to hold just our school's applicant data. I want to be able to access that data from PeopleSoft for use in external applications, but our IT staff doesn't really seem to understand what I'm requesting, as they simply tell me I can have access to the PS query tools. The problem is, I don't want to run just ad hoc queries, I want to be able to connect from outside PeopleSoft and show current data within the external app. I am unable to find documentation or get a clear answer to my question. Does PeopleSoft support access via a web services API or anything similar, and does that sound like the right direction for me to take?

  • How to fix: "The connection to the server was reset while the page was loading."?

    - by stupidity
    I have a 64-bit Ubuntu 12.04 installed. I used to login to a website (chess.com) but since a few days ago I get this message: The connection was reset The connection to the server was reset while the page was loading. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web. This is the case in Firefox, and chrome. A friend of mine confirmed to me that the website is working fine and he could access it. And I can access many other websites and facing no issues except for this website. I tried switching the use TLS 1.0 option as suggested by someone but this didn't fix it. Can someone suggest a way to fix this issue?

  • mysql questions for beginners

    - by ankhseeker
    ok, I have a few questions regarding mysql. I am currently running ubuntu 12.04.4 LTS command line version. I am looking for a database that I can use. I am confused at this point because I am uninformed. mysql is just one database that is on the server? or can it contain several or many databases What programs do I use to access it on the server or is it a vt-100 type access? I understand that mysql comes with lamp? or ubuntu. I am thinking that it is already installed but not sure how to access it, but that is another question for later. Outside of the man pages and the ubuntu manual, is there a site for its setup and use? Thanks!

  • Joomla: How can I prevent certain user from visiting a certain page?

    - by user6657
    I have an internal section in my Joomla only for "Registered" users. There they can edit preferences. Multiple users can access the same preferences (different stakeholders). Now I have "smithcorp" and "smithcorp_guest". They should both be able to view the same things, but "smithcorp_guest" shouldn't be able to edit the preferences. Is there a way to forbid "smithcorp_guest" access to this page? I have only seen access regulation via the user level, i.e. unregistered, registered, admin.

  • .NET: Can I use DataContractJsonSerializer to serialize to a JSON associative array?

    - by Cheeso
    When using DataContractJsonSerializer to serialize a dictionary, like so: [CollectionDataContract] public class Clazz : Dictionary<String,String> {} .... var c1 = new Clazz(); c1["Red"] = "Rosso"; c1["Blue"] = "Blu"; c1["Green"] = "Verde"; Serializing c1 with this code: var dcjs = new DataContractJsonSerializer(c1.GetType()); var json = new Func<String>(() => { using (var ms = new System.IO.MemoryStream()) { dcjs.WriteObject(ms, c1); return Encoding.ASCII.GetString(ms.ToArray()); } })(); ...produces this JSON: [{"Key":"Red","Value":"Rosso"}, {"Key":"Blue","Value":"Blu"}, {"Key":"Green","Value":"Verde"}] But, this isn't a Javascript associative array. If I do the corresponding thing in javascript: produce a dictionary and then serialize it, like so: var a = {}; a["Red"] = "Rosso"; a["Blue"] = "Blu"; a["Green"] = "Verde"; // use utility class from http://www.JSON.org/json2.js var json = JSON.stringify(a); The result is: {"Red":"Rosso","Blue":"Blu","Green":"Verde"} How can I get DCJS to produce or consume a serialized string for a dictionary, that is compatible with JSON2.js ? I know about JavaScriptSerializer from ASP.NET. Not sure if it's very WCF friendly. Does it respect DataMember, DataContract attributes?

  • C# code to GZip and upload a string to Amazon S3

    Hello. I currently use the following code to retrieve and decompress string data from Amazon C#: GetObjectRequest getObjectRequest = new GetObjectRequest().WithBucketName(bucketName).WithKey(key); using (S3Response getObjectResponse = client.GetObject(getObjectRequest)) { using (Stream s = getObjectResponse.ResponseStream) { using (GZipStream gzipStream = new GZipStream(s, CompressionMode.Decompress)) { StreamReader Reader = new StreamReader(gzipStream, Encoding.Default); string Html = Reader.ReadToEnd(); parseFile(Html); } } } I want to reverse this code so that I can compress and upload string data to S3 without being written to disk. I tried the following, but I am getting an Exception: using (AmazonS3 client = Amazon.AWSClientFactory.CreateAmazonS3Client(AWSAccessKeyID, AWSSecretAccessKeyID)) { string awsPath = AWSS3PrefixPath + "/" + keyName+ ".htm.gz"; byte[] buffer = Encoding.UTF8.GetBytes(content); using (MemoryStream ms = new MemoryStream()) { using (GZipStream zip = new GZipStream(ms, CompressionMode.Compress)) { zip.Write(buffer, 0, buffer.Length); PutObjectRequest request = new PutObjectRequest(); request.InputStream = ms; request.Key = awsPath; request.BucketName = AWSS3BuckenName; using (S3Response putResponse = client.PutObject(request)) { //process response } } } } The exception I am getting is: Cannot access a closed Stream.

  • A list of Entity Framework providers for various databases

    - by Robert Koritnik
    Which providers are there and your experience using them I would like to know about all possible native .net Framework Entity Framework providers that are out there as well as their limitations compared to the default Linq2Entities (from MS for MS SQL). If there are more for the same database even better. Tell me and I'll be updating this post with this list.

Entity Framework 1 Microsoft SQL Server Standard/Enterprise/Express Linq 2 Entities - Microsoft SQL Server connector DataDirect ADO.NET Data Providers Microsoft SQL Server CE (Compact Edition) Any provider? MySQL MySQL Connector (since version 6.0) - I've read about issues when using Skip(), Take() and Sort() in the same expression tree - everyone welcome to input their experience/knowledge regarding this. (NOTE: MySQL Connector/NET Visual Studio Integration is not supported in the Express Editions of Visual Studio, meaning you won't be able to view MySQL databases in the Database explorer window or add a MySQL data source via Visual Studio wizard dialog boxes.

  • Linq, Left Join and Dates...

    - by BitFiddler
    So my situation is that I have a linq-to-sql model that does not allow dates to be null in one of my tables. This is intended, because the database does not allow nulls in that field. My problem, is that when I try to write a Linq query with this model, I cannot do a left join with that table anymore because the date is not a 'nullable' field and so I can't compare it to "Nothing". Example: There is a Movie table, {ID,MovieTitle}, and a Showings table, {ID,MovieID,ShowingTime,Location} Now I am trying to write a statement that will return all those movies that have no showings. In T.SQL this would look like: Select m.* From Movies m Left Join Showings s On m.ID = s.MovieID Where s.ShowingTime is Null Now in this situation I could test for Null on the 'Location' field but this is not what I have in reality (just a simplified example). All I have are non-null dates. I am trying to write in Linq: From m In dbContext.Movies _ Group Join s In Showings on m.ID Equals s.MovieID into MovieShowings = Group _ From ms In MovieShowings.DefaultIfEmpty _ Where ms.ShowingTime is Nothing _ Select ms However I am getting an error saying 'Is' operator does not accept operands of type 'Date'. Operands must be reference or nullable types. Is there any way around this? The model is correct, there should never be a null in the Showings:ShowTime table. But if you do a left join, and there are no show times for a particular movie, then ShowTime SHOULD be Nothing for that movie... Thanks everyone for your help.

  • Binary stream 'NN' does not contain a valid BinaryHeader. Possible causes are invalid stream or obje

    - by FinancialRadDeveloper
    I am passing user defined classes over sockets. The SendObject code is below. It works on my local machine, but when I publish to the WebServer which is then communicating with the App Server on my own machine it fails. public bool SendObject(Object obj, ref string sErrMsg) { try { MemoryStream ms = new MemoryStream(); BinaryFormatter bf1 = new BinaryFormatter(); bf1.Serialize(ms, obj); byte[] byArr = ms.ToArray(); int len = byArr.Length; m_socClient.Send(byArr); return true; } catch (Exception e) { sErrMsg = "SendObject Error: " + e.Message; return false; } } I can do this fine if it is one class in my tools project and the other class about UserData just doesn't want to know. Frustrating! Ohh. I think its because the UserData class has a DataSet inside it. Funnily enough I have seen this work, but then after 1 request it goes loopy and I can't get it to work again. Anyone know why this might be? I have looked at comparing the dlls to make sure they are the same on the WebServer and on my local machine and they look to be so as I have turned on versioning in the AssemblyInfo.cs to double check. Edit: Ok it seems that the problem is with size. If I keep it under 1024 byes ( I am guessing here) it works on the web server and doesnt if it has a DataSet inside it.k In fact this is so puzzling I converted the DataSet to a string using ds.GetXml() and this also causes it to blow up. :( So it seems that across the network something with my sockets is wrong and doesn't want to read in the data. JonSkeet where are you. ha ha. I would offer Rep but I don't have any. Grr

  • Separation of multipage tiff with compression "CCITT T.6" very slow

    - by Alex
    I need to separate multiframe tiff files, and use the following method: public static Image[] GetFrames(Image sourceImage) { Guid objGuid = sourceImage.FrameDimensionsList[0]; FrameDimension objDimension = new FrameDimension(objGuid); int frameCount = sourceImage.GetFrameCount(objDimension); Image[] images = new Image[frameCount]; for (int i = 0; i < frameCount; i++) { MemoryStream ms = new MemoryStream(); sourceImage.SelectActiveFrame(objDimension, i); sourceImage.Save(ms, ImageFormat.Tiff); images[i] = Image.FromStream(ms); } return images; } It works fine, but if the source image was encoded using the CCITT T.6 compression, separating a 20-frame-file takes up to 15 seconds on my 2,5ghz CPU.(edit: One core is at 100% during the process) When saving the images afterward to a single file using standard compression (LZW), the separation time of the LZW-file is under 1 second. Saving with CCITT compression also takes very long. Is there a way to speed up the process?

  • Displaying ppt, doc, and xls in UIWebView doesn't work but pdf does

    - by slugolicious
    It looks like a few people on stackoverflow get this to work but their code isn't posted. I'm using [web loadData:data MIMEType:MIMEType textEncodingName:@"UTF-8" baseURL:nil]; where MIMEType is: @"application/vnd.ms-powerpoint" @"application/vnd.ms-word" @"application/vnd.ms-excel" (BTW, I've seen DOC files use mimetype @"application/msword" but the "vnd" version seems more appropriate. I tried both just in case.) I verified that my 'data' is correct. PDF and TXT files work. When the UIWebView displays PPT, DOC, or XLS files, it's blank. I put NSLOG statements in my UIWebViewDelegate calls. shouldStartLoadWithRequest:<NSMutableURLRequest about:blank> navType:5 webViewDidStartLoad: didFailLoadWithError:Error Domain=NSURLErrorDomain Code=100 UserInfo=0x122503a0 "Operation could not be completed. (NSURLErrorDomain error 100.)" didFailLoadWithError:Error Domain=WebKitErrorDomain Code=102 UserInfo=0x12253840 "Frame load interrupted" so obviously the load is failing, but why? If I change my mimetype to @"text/plain" for a PPT file, the UIWebView loads fine and displays unprintable characters, as expected. That's telling me the 'data' passed to loadData: is ok. Meaning my mimetypes are bad? And just to make sure my PPT, DOC, and XLS files are indeed ok to display, I created a simple html file with anchor tags to the files. When the html file is displayed in Safari on the iPhone, clicking on the files displays correctly in Safari. I tried to research the error code displayed in didFailLoadWithError (100) but all the documented error codes are negative and greater than 1000 (as seen in NSURLError.h). -(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error { NSLog(@"didFailLoadWithError:%@", error); }

  • Why does ObservableCollection throws an exception when being modified?

    Hi! My application uses a WPF DataGrid. One of the columns is a template column that containts a combobox bound to an ObservableCollection of the entity which feeds the row. When I add a value to the ObservableCollection, a NullReferenceException is thrown. Has anybody an idea why this happens? Here is the stacktrace of the exception: at MS.Internal.Data.PropertyPathWorker.DetermineWhetherDBNullIsValid() at MS.Internal.Data.PropertyPathWorker.get_IsDBNullValidForUpdate() at MS.Internal.Data.ClrBindingWorker.get_IsDBNullValidForUpdate() at System.Windows.Data.BindingExpression.ConvertProposedValue(Object value) at System.Windows.Data.BindingExpressionBase.UpdateValue() at System.Windows.Data.BindingExpression.Update(Boolean synchronous) at System.Windows.Data.BindingExpressionBase.Dirty() at System.Windows.Data.BindingExpression.SetValue(DependencyObject d, DependencyProperty dp, Object value) at System.Windows.DependencyObject.SetValueCommon(DependencyProperty dp, Object value, PropertyMetadata metadata, Boolean coerceWithDeferredReference, OperationType operationType, Boolean isInternal) at System.Windows.DependencyObject.SetValue(DependencyProperty dp, Object value) at System.Windows.Controls.Primitives.Selector.UpdatePublicSelectionProperties() at System.Windows.Controls.Primitives.Selector.SelectionChanger.End() at System.Windows.Controls.Primitives.Selector.OnItemsChanged(NotifyCollectionChangedEventArgs e) at System.Windows.Controls.ItemsControl.OnItemCollectionChanged(Object sender, NotifyCollectionChangedEventArgs e) at System.Collections.Specialized.NotifyCollectionChangedEventHandler.Invoke(Object sender, NotifyCollectionChangedEventArgs e) at System.Windows.Data.CollectionView.OnCollectionChanged(NotifyCollectionChangedEventArgs args) at System.Windows.Controls.ItemCollection.System.Windows.IWeakEventListener.ReceiveWeakEvent(Type managerType, Object sender, EventArgs e) at System.Windows.WeakEventManager.DeliverEventToList(Object sender, EventArgs args, ListenerList list) at System.Windows.WeakEventManager.DeliverEvent(Object sender, EventArgs args) at System.Collections.Specialized.CollectionChangedEventManager.OnCollectionChanged(Object sender, NotifyCollectionChangedEventArgs args) at System.Windows.Data.CollectionView.OnCollectionChanged(NotifyCollectionChangedEventArgs args) at System.Windows.Data.ListCollectionView.ProcessCollectionChangedWithAdjustedIndex(NotifyCollectionChangedEventArgs args, Int32 adjustedOldIndex, Int32 adjustedNewIndex) at System.Windows.Data.ListCollectionView.ProcessCollectionChanged(NotifyCollectionChangedEventArgs args) at System.Windows.Data.CollectionView.OnCollectionChanged(Object sender, NotifyCollectionChangedEventArgs args) at System.Collections.ObjectModel.ObservableCollection`1.OnCollectionChanged(NotifyCollectionChangedEventArgs e) at System.Collections.ObjectModel.ObservableCollection`1.InsertItem(Int32 index, T item) at System.Collections.ObjectModel.Collection`1.Add(T item) at ORF.PersonBook.IdentityModule.Model.SubsidiaryModel.AddRoom(RoomModel room) in C:\Project\Phoenix\Development\src\ORF.PersonBook.IdentityModule\Model\SubsidiaryModel.cs:line 127
