  • Dell Inspiron 1525 - internal hard drive not detected

    - by GingerT
    Others have asked about this issue but had intermittent access to their HD, therefore their results did not apply to this situation. I have tried reseating the HD to no effect. I also tried booting from the Internal HD to no effect. Next step get a connector cable and move the data to a different HD, or send in for HD recovery? Any suggestions?

  • Mounting /var /tmp /var/log to separate partition

    - by William MacDonald
    Per DISA hardening requirements for RHEL, I'm supposed to make sure a number of locations on the filesystem are mounted on separate partitions. A few of the locations they specify include /var /tpm /var/log etc. Is it possible to go about doing this on a live machine (without booting a separate OS)? And how would I go about doing that. I've backed up the OS so if I do screw something up I can recover. Thanks!

  • jQuery/ajax working on IIS5.1 but not IIS6

    - by Mikejh99
    I'm running a weird issue here. I have code that makes jquery ajax calls to a web service and dynamically adds controls using jquery. Everything works fine on my dev machine running IIS 5.1, but not when deployed to IIS 6. I'm using VS2010/ASP.Net 4.0, C#, jQuery 1.4.2 and jQuery UI 1.8.1. I'm using the same browser for each. It partially works though. The code will add the controls to the page, but they aren't visible until I click them (they aren't visible though). I thought this was a css issue, but the styles are there too. The ajax calls look like this: $.ajax({ url: "/WebServices/AssetManager.asmx/Assets", type: "POST", datatype: "json", async: false, data: "{'q':'" + req.term + "', 'type':'Condition'}", contentType: "application/javascript; charset=utf-8", success: function (data) { res($.map(data.d, function (item) { return { label: item.Name, value: item.Name, id: item.Id, datatype: item.DataType } })) } }) Changing the content-type makes the autocomplete fail. I've quadruple checked and all the paths are correct, there is no document footer enabled in IIS, and I'm not using IIS compression. Any idea why the page will display and work properly in IIS 5 but only partially in IIS 6? (If it failed completely, that'd make more sense!). Is it a jQuery or CSS issue?

  • Windows 64bit Sandboxing software alternatives

    - by Pacifika
    As you might know sandboxing software doesn't work in 64bit Windows due to patchguard. What are the alternatives for a person looking to test untrusted / temporary software? Edit: @Nick I'd prefer an alternative to VMs as I'm not happy with the extended startup time, the extra login sequences and the memory overhead that accompanies booting a VM solution to test something out ocassionally as a home user. Also it's another system that needs to be kept secure and up to date.

  • How to boot a Linux live USB on a Mac?

    - by nambuls
    I have a USB stick with a Fedora 11 live environment on it. It's booting fine on 3 PCs where I've tried it. But I can't get it to boot on a Mac (Intel). When pressing the alt key (or command key, I don't remember which one) during startup I can only choose the "Macintosh HD" and the USB stick doesn't appear.

  • Creating a Ruby method that pads an Array

    - by CJ Johnson
    I'm working on creating a method that pads an array, and accepts 1. a desired value and 2. an optional string/integer value. Desired_size reflects the desired number of elements in the array. If a string/integer is passed in as the second value, this value is used to pad the array with extra elements. I understand there is a 'fill' method that can shortcut this - but that would be cheating for the homework I'm doing. The issue: no matter what I do, only the original array is returned. I started here: class Array def pad(desired_size, value = nil) desired_size >= self.length ? return self : (desired_size - self.length).times.do { |x| self << value } end end test_array = [1, 2, 3] test_array.pad(5) From what I researched the issue seemed to be around trying to alter self's array, so I learned about .inject and gave that a whirl: class Array def pad(desired_size, value = nil) if desired_size >= self.length return self else (desired_size - self.length).times.inject { |array, x| array << value } return array end end end test_array = [1, 2, 3] test_array.pad(5) The interwebs tell me the problem might be with any reference to self so I wiped that out altogether: class Array def pad(desired_size, value = nil) array = [] self.each { |x| array << x } if desired_size >= array.length return array else (desired_size - array.length).times.inject { |array, x| array << value } return array end end end test_array = [1, 2, 3] test_array.pad(5) I'm very new to classes and still trying to learn about them. Maybe I'm not even testing them the right way with my test_array? Otherwise, I think the issue is I get the method to recognize the desired_size value that's being passed in. I don't know where to go next. Any advice would be appreciated. Thanks in advance for your time.

  • Android Remote Video with Titanium

    - by Tim
    Greetings all! I'm trying to play a video that is hosted on our webserver on an android phone. I've already built this for iPhone and it works great. Droid, however is a different issue. Instead of getting video, I'm just getting a black screen, no error or anything. The code I am using is: activeContent = Titanium.Media.createVideoPlayer({ contentURL: content, backgroundColor:'#111', movieControlMode:Titanium.Media.VIDEO_CONTROL_DEFAULT }); win.add(activeContent); activeContent.play(); The video I'm downloading does play on the droid when not using Titanium, so I know its not a format issue. (its an .MP4 incase anyone is wondering.) I've used Titanium SDK's 1.5.1 and am on the continuous build of 1.6.0 from earlier today. using the 2.2 Droid SDK, and Titanium Developer 1.2.2 Does anyone have any thoughts on this? One of the big selling points for android is its ability to pull media from the net, and I'm honestly a little concerned about this shortcoming if its an issue with Titanium.

  • ADO.NET DataTable/DataRow Thread Safety

    - by Allen E. Scharfenberg
    Introduction A user reported to me this morning that he was having an issue with inconsistent results (namely, column values sometimes coming out null when they should not be) of some parallel execution code that we provide as part of an internal framework. This code has worked fine in the past and has not been tampered with lately, but it got me to thinking about the following snippet: Code Sample lock (ResultTable) { newRow = ResultTable.NewRow(); } newRow["Key"] = currentKey; foreach (KeyValuePair<string, object> output in outputs) { object resultValue = output.Value; newRow[output.Name] = resultValue != null ? resultValue : DBNull.Value; } lock (ResultTable) { ResultTable.Rows.Add(newRow); } (No guarantees that that compiles, hand-edited to mask proprietery information.) Explanation We have this cascading type of locking code other places in our system, and it works fine, but this is the first instance of cascading locking code that I have come across that interacts with ADO .NET. As we all know, members of framework objects are usually not thread safe (which is the case in this situation), but the cascading locking should ensure that we are not reading and writing to ResultTable.Rows concurrently. We are safe, right? Hypothesis Well, the cascading lock code does not ensure that we are not reading from or writing to ResultTable.Rows at the same time that we are assigning values to columns in the new row. What if ADO .NET uses some kind of buffer for assigning column values that is not thread safe--even when different object types are involved (DataTable vs. DataRow)? Has anyone run into anything like this before? I thought I would ask here at StackOverflow before beating my head against this for hours on end :) Conclusion Well, the consensus appears to be that changing the cascading lock to a full lock has resolved the issue. That is not the result that I expected, but the full lock version has not produced the issue after many, many, many tests. The lesson: be wary of cascading locks used on APIs that you do not control. Who knows what may be going on under the covers!

  • UITableView UITableViewCell dynamic UILabel Height storyboard

    - by Mikel Nelson
    This isn'an a question, just a results log on an issue I had with XCode 4.5 storyboards and dynamic height UITableCell with a UILabel. The issue was; the initial display of a cell would only show part of the resized UILabel contents, and that the visual UILabel was not resized. It would only display correctly after scrolling off the top of the Table and back down. I did the calculations in hieghtForRowAtIndexPath and sizeToFit the UILabel in rowAtIndexPath. The sizes where coming up ok in debug, but the device was not updating the display with the correct size and UILable.text value. I had created the dynamic UITableCell in a storyboard. However, I had set the width and height to a nominal value (290x44). It turns out, this was causing my issues. I set the width and height to zero (0) in the story board, and everything started working correctly. (i.e. the UILabels displayed at the correct size with full content). I was unable to find anything online on this issue, except for some references to creating the custom table cell with a frame of zero. Turns out, that was really the answer (for me).

  • Guid Primary /Foreign Key dilemma SQL Server

    - by Xience
    Hi guys, I am faced with the dilemma of changing my primary keys from int identities to Guid. I'll put my problem straight up. It's a typical Retail management app, with POS and back office functionality. Has about 100 tables. The database synchronizes with other databases and receives/ sends new data. Most tables don't have frequent inserts, updates or select statements executing on them. However, some do have frequent inserts and selects on them, eg. products and orders tables. Some tables have upto 4 foreign keys in them. If i changed my primary keys from 'int' to 'Guid', would there be a performance issue when inserting or querying data from tables that have many foreign keys. I know people have said that indexes will be fragmented and 16 bytes is an issue. Space wouldn't be an issue in my case and apparently index fragmentation can also be taken care of using 'NEWSEQUENTIALID()' function. Can someone tell me, from there experience, if Guid will be problematic in tables with many foreign keys. I'll be much appreciative of your thoughts on it...

  • How can I change a form's input value with javascript

    - by Biroka
    How can I change a form's input value with javascript depending on witch combobox item is selected. I have a form with some imported values, and there is a field of witch imported value can be changed via a combobox. In my case: print("<input type='hidden' name='issue_array[{$issue["nr"]}][\"supplier\"]' value='{$issue["supplier"]}' />"); I have a combobox, that if I change it's value, should change the value of the input above. This is what I tried: print("<select name='supplier_combo' onchange='setSupplierInputValue(this.value, ${issue['nr']})'>"); and the script: echo "\r\n" . '<SCRIPT TYPE="text/javascript">' . "\r\n"; echo 'function setSupplierInputValue(value, issue_nr)' . "\r\n"; echo '{' . "\r\n"; echo ' issue_array[issue_nr]["supplier"] = value;'; echo '}' . "\r\n"; echo '</SCRIPT>'. "\r\n"; But it doesn't work, please help.

  • No Firefox UI if launched during boot-up

    - by kpax
    At work I'm using Windows XP SP2. What I've noticed is if I launch Firefox while Windows hasn't finished booting up, it launches the firefox.exe process but fails to launch the associated UI i.e. there's no Firefox window at the end of it. The only way to resolve this is to kill the firefox.exe process and re-launch Firefox. Has anyone else experienced this kind of behavior? Update: I'm using Firefox 3.6

  • Database.ExecuteNonQuery does not return

    - by dan-waterbly
    I have a very odd issue. When I execute a specific database stored procedure from C# using SqlCommand.ExecuteNonQuery, my stored procedure is never executed. Furthermore, SQL Profiler does not register the command at all. I do not receive a command timeout, and no exeception is thrown. The weirdest thing is that this code has worked fine over 1,200,000 times, but for this one particular file I am inserting into the database, it just hangs forever. When I kill the application, I receive this error in the event log of the database server: "A fatal error occurued while reading the input stream from the network. The session will be terminated (input error: 64, output error: 0). Which makes me think that the database server is receiving the command, though SQL Profiler says otherwise. I know that the appropiate permissions are set, and that the connection string is right as this piece of code and stored procedure works fine with other files. Below is the code that calls the stored procedure, it may be important to note that the file I am trying to insert is 33.5MB, but I have added more than 10,000 files larger than 500MB, so I do not think the size is the issue: using (SqlConnection sqlconn = new SqlConnection(ConfigurationManager.ConnectionStrings["TheDatabase"].ConnectionString)) using (SqlCommand command = sqlconn.CreateCommand()) { command.CommandText = "Add_File"; command.CommandType = CommandType.StoredProcedure; command.CommandTimeout = 30 //should timeout in 30 seconds, but doesn't... command.Parameters.AddWithValue("@ID", ID).SqlDbType = SqlDbType.BigInt; command.Parameters.AddWithValue("@BinaryData", byteArr).SqlDbType = SqlDbType.VarBinary; command.Parameters.AddWithValue("@FileName", fileName).SqlDbType = SqlDbType.VarChar; sqlconn.Open(); command.ExecuteNonQuery(); } There is no firewall between the server making the call and the database server, and the windows firewalls have been disabled to troubleshoot this issue.

  • Computer no display from connection problem.

    - by whamsicore
    My computer is booting but has no display. The optical drive has power, but the USB doesn't, so I figured that I had a broken motherboard. However I tried to boot my computer again laying flat, and it worked fine for two seconds, and then froze like it did the first time. It had no display after that. I have come to the conclusion that it is a connection problem (someone had a similar problem on one of the online forums).

  • jQuery resizable() dynamic maxWidth option

    - by Vitaliy Isikov
    I have 3 columns that are resizable. When one is made wider, the one to it's left is made smaller. Essentially there are only 2 handles. Left col and Mid col. So when Mid col is made thinner, Right col expands accordingly. All three of them are contained with a 900px parent div, so the sum of all three is always 900. They have max and min widths set statically. My issue is that if you take the left handle and move it all the way to the right you're still able to use the right handle and expand the mid col past the edge of the parent div. I thought of a way to solve that issue by writing up a function that checks the widths of the columns and then subtracts left and right columns from the parent div width, I called it mWid. This leaves me with the number I want to set as the maxWidth for Mid col. Now the issue is that mWid is not gettings updated for here "maxWidth: mWid" Here is what the function for the right handle looks like: $(function() { $("#midResizable").resizable({ handles: 'e', containment: '#container', maxWidth: mWid, // gets set once, but doesn't update! WHY? minWidth: 195, resize: function(event, ui) { contWidth = $('#container').width() newWidth = $(this).width() leftWidth = $('#leftResizable').width() rightWidth = $('#rightResizable').width() $("#rightResizable").css("width", (contWidth-15)-(newWidth)-(leftWidth)+"px"); checkWid() } }); }); function checkWid() { rightWidth = $('#rightResizable').width() leftWidth = $('#leftResizable').width() contWidth = $('#container').width() mWid = (contWidth-15)-(rightWidth)-(leftWidth) }

  • Long running method causing race condition

    - by keeleyt83
    Hi, I'm relatively new with hibernate so please be gentle. I'm having an issue with a long running method (~2 min long) and changing the value of a status field on an object stored in the DB. The pseudo-code below should help explain my issue. public foo(thing) { if (thing.getStatus() == "ready") { thing.setStatus("finished"); doSomethingAndTakeALongTime(); } else { // Thing already has a status of finished. Send the user back a message. } } The pseudo-code shouldn't take much explanation. I want doSomethingAndTakeALongTime() to run, but only if it has a status of "ready". My issue arises whenever it takes 2 minutes for doSomethingAndTakeALongTime() to finish and the change to thing's status field doesn't get persisted to the database until it leaves foo(). So another user can put in a request during those 2 minutes and the if statement will evaluate to true. I've already tried updating the field and flushing the session manually, but it didn't seem to work. I'm not sure what to do from here and would appreciate any help. PS: My hibernate session is managed by spring.

  • Being pressured to GOTO the dark-side

    - by Dan McG
    We have a situation at work where developers working on a legacy (core) system are being pressured into using GOTO statements when adding new features into existing code that is already infected with spagetti code. Now, I understand there may be arguments for using 'just one little GOTO' instead of spending the time on refactoring to a more maintainable solution. The issue is, this isolated 'just one little GOTO' isn't so isolated. At least once every week or so there is a new 'one little GOTO' to add. This codebase is already a horror to work with due to code dating back to or before 1984 being riddled with GOTOs that would make many Pastafarians believe it was inspired by the Flying Spagetti Monster itself. Unfortunately the language this is written in doesn't have any ready made refactoring tools, so it makes it harder to push the 'Refactor to increase productivity later' because short-term wins are the only wins paid attention to here... Has anyone else experienced this issue whereby everybody agrees that we cannot be adding new GOTOs to jump 2000 lines to a random section, but continually have Anaylsts insist on doing it just this one time and having management approve it? tldr; How can one go about addressing the issue of developers being pressured (forced) to continually add GOTO statements (by add, I mean add to jump to random sections many lines away) because it 'gets that feature in quicker'? I'm beginning to fear we may loses valuable developers to the raptors over this...

  • Avoiding mass propagation of properties and events for exposure to ViewModels.

    - by firoso
    I have an MVVM application I am developing that is to the point where I'm ready to start putting together a user interface (my client code is largely functional) I'm now running into the issue that I'm trying to get my application data to where I need it so that it can be consumed by the view model and then bound to the view. Unfortunately, it seems that I've either got a few structural oversights, or I'm just going to have to face the reality that I need to be propogating events and raising excessive amounts of errors to notify view models that thier properties have changed. Let me go into some examples of my issue: I have a class "Unit" contained in a class "Test", contained in a class "Session" contained in a class "TestManager" which is contained in "TestDataModel" which is utilized by "TestViewModel" which is databound to by my "TestView" .... WHOA. Now, consider that Unit (the bottom of the heiarchy) has a property called "Results" that is updated periodically, I want to expose that to my viewmodel and then databind it to my view, trouble is, the only way I can really think to do this is to perpetuate events WAY up a chain that say "I've been updated!" and then request the new value... This seems like an aweful way to do this. Alternatively, I could register a static event and raise it, and have the appropriate "Unit view model" grab the event and request the update. This SEEMS better... but... static events? Is that a taboo idea? Also, having an expression like: TestDataModel.TestManager.Session.Test.Unit.Results[i] Seems REALLY gross to have on a View Model. I know this all reeks of a bad design issue, but I can't figure out what I did wrong? Should I be using more singleton/container controlled lifetimes type objects? Register object instances with static helper containers? Obviously these are hard questions to answer without being intimate with the existing structure, but if you've run into situations like this, what did you do to refactor? Should I just live with this, add mass events, and propogate them?

  • psqlODBC won't load after installing MS SQL ODBC driver on RHEL 6

    I had the PostgreSQL drivers working on my RHEL 6. But after I installed Microsoft® SQL Server® ODBC Driver 1.0 for Linux I can no longer connect to PosgreSQL data sources. I can connect to SQL Server data sources fine. When I had this same issue a week ago I uninstalled MS SQL Server ODBC driver from Linux and it fixed the issue. I had to copy the psqlodbcw.so files from another machine to replenish the files. I don't want to do the same this time. I want both drivers to work on Linux. This time around the setup files got deleted: /usr/lib64/libodbcpsqlS.so. Replenishing it did not fix the issue.

  • Mysterious horizontal lines on my site when rendered on iPad

    - by Ferdy
    The following site: http://staging.jungledragon.com Has a few rendering issues on the iPad using Safari, so I'm trying to fix them. There is one issue where I am stuck though. If you have an iPad, open the site in portrait mode. There are two unwanted horizontal lines appearing, a top one that crosses the tabs (Popular, Fresh, etc) and a bottom one that sits right above the lizard illustration. Both lines should not be there. These lines do not appear on any other browser tested, including Safari on Windows. When you move that same site into landscape mode on the iPad, the top horizontal line dissapears, whilst the bottom one stays. If you zoom in a bit to the bottom line, it then dissapears too. I've been trying out various CSS fixes to no avail and am now beginning to think this is a rendering issue of Safari, although possibly triggered by me. Any help is greatly appreciated. It seems like a minor issue but I hate sloppiness.

  • How to deal with a flaw in System.Data.DataTableExtensions.CopyToDataTable()

    - by andy
    Hey guys, so I've come across something which is perhaps a flaw in the Extension method .CopyToDataTable. This method is used by Importing (in VB.NET) System.Data.DataTableExtensions and then calling the method against an IEnumerable. You would do this if you want to filter a Datatable using LINQ, and then restore the DataTable at the end. i.e: Imports System.Data.DataRowExtensions Imports System.Data.DataTableExtensions Public Class SomeClass Private Shared Function GetData() As DataTable Dim Data As DataTable Data = LegacyADO.NETDBCall Data = Data.AsEnumerable.Where(Function(dr) dr.Field(Of Integer)("SomeField") = 5).CopyToDataTable() Return Data End Function End Class In the example above, the "WHERE" filtering might return no results. If this happens CopyToDataTable throws an exception because there are no DataRows. Why? The correct behavior should be to return a DataTable with Rows.Count = 0. Can anyone think of a clean workaround to this, in such a way that whoever calls CopyToDataTable doesn't have to be aware of this issue? System.Data.DataTableExtensions is a Static Class so I can't override the behavior....any ideas? Have I missed something? cheers UPDATE: I have submitted this as an issue to Connect. I would still like some suggestions, but if you agree with me, you could vote up the issue at Connect via the link above cheers
