• Windows undetectable after interrupted chkdsk

  - by Felthragar

  I have a computer that is running Windows XP. For some reason, the other day it wouldn't start giving me the following message: "ntoskrnl.exe is missing or corrupt" So I put the XP disc in the tray and fired up the repair console and ran the following: chkdsk /r It was on for about eight hours and it got to about 52% I believe. Then there was a power outage and the computer shut down (obviously). Today when I was booting it, it isn't even detecting there's an OS anymore. If I boot the computer with no cd in the tray it says: "Reboot and select a proper Boot device or Insert Boot Media in selected Boot device and press a key" If I run the repair console, or the xp installation program it isn't finding any OS installations. Any ideas on what to do next? Any help is appreciated. Thanks! Update: After turning boot-time diagnostics on, I got this message when booting without cd (instead of the previous one): "Couldn't open drive multi(0)disk(0)rdisk(0)partition(2)"

• Weird windows quirk when renaming file

  - by Roy Rico

  Hi, I am finding when I try to rename a file in windows 7, i typically select the file i want to rename, hit F2 (rename) and type the new name. I've been getting this weird bug which the while file name gets selected again, sometimes right in the middle of me typing. I can sit there and watch it reselect the entire filename every second or so as if someone is invisibly hitting control+a while type. I have tried making sure that my keys aren't being pressed, and also have even gotten a new keyboard and this problem still consists. I know it'll probably be a long shot, but just hoping someone's seen this issue and has a resolution. UPDATE: This is on a desktop machine, not a laptop, so there's no issue with Trackpad.

• PHP JQuery: Where to specify uploadify destination folder

  - by Eamonn

  I have an uploadify script running, basic setup. Works fine when I hard code the destination folder for the images into uploadify.php - now I want to make that folder dynamic. How do I do this? I have a PHP variable $uploadify_path which contains the path to the folder I want. I have switched out my hard coded $targetPath = path/to/directory for $targetPath = $uploadify_path in both uploadify.php and check_exists.php, but it does not work. The file upload animation runs, says it is complete, yet the directory remains empty. The file is not hiding out somewhere else either. I see there is an option in the Javascript to specify a folder. I tried this also, but to no avail. If anyone could educate me on how to pass this variable destination to uploadify, I'd be very grateful. I include my current code for checking (basically default): The Javascript <script type="text/javascript"> $(function() { $('#file_upload').uploadify({ 'swf' : 'uploadify/uploadify.swf', 'uploader' : 'uploadify/uploadify.php', // Put your options here }); }); </script> uploadify.php $targetPath = $_SERVER['DOCUMENT_ROOT'] . $uploadify_path; // Relative to the root if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetFile = $targetPath . $_FILES['Filedata']['name']; // Validate the file type $fileTypes = array('jpg','jpeg','gif','png'); // File extensions $fileParts = pathinfo($_FILES['Filedata']['name']); if (in_array($fileParts['extension'],$fileTypes)) { move_uploaded_file($tempFile,$targetFile); echo '1'; } else { echo 'Invalid file type.'; } }

• xcode project-/target-settings-syntax for linker flag force_load on iPhone

  - by Kaiserludi

  Hi all. I am confronted with the double bind, that on the one hand for one of the 3rd party static libraries, my iPhone application uses, the linker flag -all_load has to be set in the application project- or target settings, otherwise the app crashes at runtime not finding some symbols, called internally from the lib, on the other hand for another 3rd party static lib -all_load must not be set on application level, or the app won't build thanks to a "duplicate symbols"-linker error. To solve this issue I now want to use force_load instant of load_all, as it due to documentation it does the same like all_load, but only for the passed path or lib-file, instead of all libs. The problem with force_load is, I do not have a clue, how to pass a path or file as parameter with it, when passing it via xcode project- or target-settings. All syntax-possibilities coming to my mind either lead into xcode thinking its another linker flag instead of a parameter to the previous one, or the linker is throwing syntax related errors or the flag simply does nothing at all in comparison to not being set. I also opened the .pbxproj-file in a text-editor to edit it to the correct command line syntax manually, but when reloading the project with xcode, it auto changes the syntax into interpreting the parameter to force_load as a separate flag. Anyone having an idea on this issue? Thx, Kaiserludi.

• Short names versus long names in Windows

  - by normski

  I have some code which gets the short name from a file path, using GetShortNameW(), and then later retrieves the long name view GetLongNameA(). The original file is of the form "C:/ProgramData/My Folder/File.ext" However, following conversion to short, then back to long, the filename becomes "C:/Program Files/My Folder/Filename.ext". The short name is of the form "C:/PROGRA~2/MY_FOL~1/FIL~1.EXT" The short name is being incorrectly resolved. The code compiles using VS 2005 on Windows 7 (I cannot upgrade the project to VS2008) Does anybody have any idea why this might be happening? DWORD pathLengthNeeded = ::GetShortPathNameW(aRef->GetFilePath().c_str(), NULL, 0); if(pathLengthNeeded != 0) { WCHAR* shortPath = new WCHAR[pathLengthNeeded]; DWORD newPathNameLength = ::GetShortPathNameW(aRef->GetFilePath().c_str(), shortPath, pathLengthNeeded); if(newPathNameLength != 0) { UI_STRING unicodePath(shortPath); std::string asciiPath = StringFromUserString(unicodePath); pathLengthNeeded = ::GetLongPathNameA(asciiPath.c_str(),NULL, 0); if(pathLengthNeeded != 0) {// convert it back to a long path if possible. For goodness sake can't we use Unicode throughout?F char* longPath = new char[pathLengthNeeded]; DWORD newPathNameLength = ::GetLongPathNameA(asciiPath.c_str(), longPath, pathLengthNeeded); if(newPathNameLength != 0) { std::string longPathString(longPath, newPathNameLength); asciiPath = longPathString; } delete [] longPath; } SetFullPathName(asciiPath); } delete [] shortPath; }

• Intel RAID0 on Windows 8 not Displaying Correct Media Type

  - by kobaltz

  I have my primary C Drive which consists of 2 Intel 120GB SSD Drives in a RAID0. I have a clean install of Windows 8 Pro, latest MEI software, latest RST software, latest Intel Toolbox. Prior to this I had installed Windows 8 Pro as an upgrade. When I went into the Optimize Drives while in the Upgrade installation, it showed the Media Types as Solid State Drives. However, now since I am in a brand new install, it is showing the Media Type as Hard Disk Drive. I am worried about this because of the trim not working properly. Before when in the upgrade, it showed SSD as the media type and the Optimize option would perform a manual trim. Unfortunately, my search credentials on Google are so common to many other things (ie Raid0, SSD, Windows 8, Media Type) that all I am finding are useless topics. Before, (found on random site) it showed the Media Type as below

• Windows 7 file sharing password protecting or making stuff available to just me

  - by Carbonara

  Even with the new Homegroup feature I'm still finding the way Windows deals with folder sharing utterly baffling. Here's what I want to do. I have two computers, a PC Desktop and a laptop. I also live in a shared flat with other computer users. I have set up a Homegroup and a Workgroup on the desktop and joined them on the laptop and in the home group I have shared video, music and pictures. This is so that anyone on the network can view pictures and listen to music etc. But I want my Documents folder from my desktop to only be available to me on my laptop and not to anyone else that may be on the network. The Homegroup only allows (from what I can gather from the baffling array of options) sharing with everyone or no one. Is it possible to only allow the laptop to access the documents folder on the desktop? The user name and password are the same on both computers.

• Workflow Automation software for SVN

  - by KyleMit

  We're currently using IBM's ClearQuest for task management and ClearCase for change management. They plug and play very well with each other. Users can create tasks in ClearCase as defects and enhancements, and developers can use those tasks to check out and modify code in source control. We're looking to upgrade to a better, more modern Source Control system, like SVN, although we're not married to that as our Source Control system. There are loads of source control systems out there, but I'm having difficulty finding one that also includes the ability to have users enter tasks and track them, especially in a native way to the source control system itself. Are there any products that replace ClearQuest for systems like SVN? Are there any other cheap / open source application pairs that handle both sides of the coin?

• Streaming Youtube Videos

  - by Vinay

  Hi All, I am writing an application to play the youtube videos using streaming. First method: I am getting the RTSP URL to the video using GData APIs. Here is the code to play the RTSP url. VideoView mVideoView = new VideoView(this); setContentView(mVideoView); mVideoView.setVideoURI(Uri.parse("rtsp://rtsp2.youtube.com/CiILENy73wIaGQkDwpjrUxOWQBMYESARFEgGUgZ2aWRlb3MM/0/0/0/video.3gp")); mVideoView.start(); But it throws error on both G1 device and emulator (Emulator has some firewall problem as per mailing list) Here is the error message ERROR/PlayerDriver(35): Command PLAYER_INIT completed with an error or info PVMFFailure Second method: A hack way to get the path of 3gp file from http://www.youtube.com/get_video?v=&t=<&<.. After getting the file path and I can call setVideoURI and it plays fine. But it is a hack way to achieve the requirement. I have checked the Youtube App also, it also does the hack way to play the youtube url.(Checked with logcat) I have tried changing from VideoView to MediaPlayer but no change in the error. Is there a "Clean" way to do this? Please let me know your thoughts.

• Using mod-rewrite to conditionally select existing file in a subdirectory based on Host header?

  - by Kevin Hakanson

  I'm working through a problem where I want to select a different static content file based on the incoming Host header. The simple example is a mapping from URLs to files like this: www.example.com/images/logo.gif - \images\logo.gif skin2.example.com/images/logo.gif - \images\skin2\logo.gif skin3.example.com/images/logo.gif - \images\skin3logo.gif I have this working with the following RewriteRules, but I don't like how I have to repeat myself so much. Each host has the same set of rules, and each RewriteCond and RewriteRule has the same path. I'd like to use the RewriteMap, but I don't know how to use it to map the %{HTTP_HOST} to the path. <VirtualHost *:80> DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs" ServerName www.example.com ServerAlias skin2.example.com ServerAlias skin3.example.com RewriteEngine On RewriteCond %{HTTP_HOST} skin2.example.com RewriteCond %{DOCUMENT_ROOT}$1/skin2/$2 -f RewriteRule ^(.*)/(.*) $1/skin2/$2 [L] RewriteCond %{HTTP_HOST} skin3.example.com RewriteCond %{DOCUMENT_ROOT}$1/skin3/$2 -f RewriteRule ^(.*)/(.*) $1/skin3/$2 [L] </VirtualHost> The concept behind the rules is if the same filename exists in a subdirectory for that host, use it instead of the direct targeted file. This uses host based subdirectories at the lowest level, and not a top level subdirectory to separate content.

• Set ContentTemplate in CodeBehind: XamlParseException 2260 Error

  - by user362215

  Hi, I'd like to change the ContentTemplate of a ContentPresenter in the CodeBehind file. But if I run the Silverlight 4 application a XamlParseException with the error code 2260 occures. foreach (ContentPresenter item in Headers) { item.ContentTemplate = Parent.UnselectedHeaderTemplate; } if ((index >= 0) && (index < Headers.Count)) { ContentPresenter item0 = (ContentPresenter)Headers[index]; item0.ContentTemplate = Parent.SelectedHeaderTemplate; } If I do only the foreach code without the code in the "if", it works. And if I only do the code in the "if" without the foreach it works too. But togheter (the "if"-code and the foreach-code) it doesn't work. I have no idea why it doesn't work. The two templates look like this: <Setter Property="UnselectedHeaderTemplate"> <Setter.Value> <DataTemplate> <ContentControl Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" Margin="10,-10" FontSize="72" Foreground="#FF999999" CacheMode="BitmapCache"/> </DataTemplate> </Setter.Value> </Setter> <!-- SelectedHeader template --> <Setter Property="SelectedHeaderTemplate"> <Setter.Value> <DataTemplate> <ContentControl Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" Margin="10,-10" FontSize="72" Foreground="{TemplateBinding Foreground}" CacheMode="BitmapCache"/> </DataTemplate> </Setter.Value> </Setter> If you have an idea what problem is please tell me.

• Showing latex commands in text string using mathjax

  - by robezy

  I have a text string, for ex. 'A vehicle travels from A to B, distance {$d} km at constant speed. While returning back to A on same path it {$variation} its speed by {$v} km/hr. The total time of journey is {$t} hours. Find the original speed of vehicle.' The variables in the curly brackets are to be replaced by appropriate latex equation. I'm using php's preg_replace to replace the variables with latex commands. Unfortunately, my latex commands are coming as it is. It is not processed by mathjax. For ex, above text becomes A vehicle travels from A to B, distance 1 km at constant speed. While returning back to A on same path it increased its speed by (\frac{3}{2}) km/hr. The total time of journey is 1 hours. Find the original speed of vehicle. The frac is show as it is. What is wrong here? Please ask me if you need any more info. Thanks

• 2.5" SSD in a 3.5" desktop drive bay normal?

  - by Cory Petosky

  I'm a little out of touch with modern desktop builds, but I recently built a new machine anyway. I want to pick up a SSD for my I/O intensive apps (EverQuest 2 and Flash CS4 mostly), but I'm having trouble finding any in the 3.5" form factor. Is this expected, or do I fail at product search? And, if it is expected, do 2.5" SSDs come with an adapter to fit them in my desktop machine, or will I need to purchase one separately? And, finally, if I do need to purchase an adapter, are they pretty standard or are some better than others. General advice is most welcomed, though specific product recommendations in addition would be helpful!

• Files slow to save sometimes after Ubuntu upgrade

  - by Matchu

  I haven't quite been able to track down why this happens sometimes in Ubuntu 10.04 and not other times. I'll go into gedit or OpenOffice.org and try to save files, and, during some sessions, it will take up to 10 seconds to save the file, sometimes causing the program to become unresponsive. But during these same sessions, the files sometimes save instantly. This didn't start happening until after the 10.04 (Lucid) upgrade. I suspect that something is reading all the changes I make, or that there's some other big file action going on, or something like that. I disabled Tracker a while back, before the upgrade, and don't see it under the settings - could it be back under a different name under Lucid? You probably don't already know the answer, but how can I go about finding the cause of this problem?

• Rails runner command not saving to cache

  - by mark

  Hi I'm having a bit of a problem with a cron task generated by rails whenever plugin that should store remote data in the rails cache for display. What I have is this: schedule.rb set :path, '/var/www/apps/tuexplore/current' every 1.hour do runner "Weather.cache_remote", :environment => :production end calls this model class Weather def self.cache_remote Rails.cache.write('weather_data', Net::HTTP.get_response(URI.parse(WEATHER_URL)).body) end end Calling whenever returns this PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/deploy/.gem/ruby/1.8/bin 0 * * * * /var/www/apps/tuexplore/current/script/runner -e production "Weather.cache_remote" This doesn't work. Calling the weather model method from a controller works fine, but I need to schedule it hourly. The cron task causes a "Cache write: weather_data" entry to appear in the production log but data isn't stored nor output into the page. Additional information, I can log into production console and run Weather.cache_remote, then read the data from the rails cache. I'd be really appreciative if someone could point out the error of my ways. If further explanation is needed please ask. Thanks in advance for any pointers.

• Python: Most efficient way to concatenate and rearrange files

  - by user300890

  Hi, I am reading from several files, each file is divided into 2 pieces, first a header section of a few thousand lines followed by a body of a few thousand. My problem is I need to concatenate these files into one file where all the headers are on the top followed by the body. Currently I am using two loops; one to pull out all the headers and write them, and the second to write the body of each file (I also include a tmp_count variable to limit the number of lines to be loading into memory before dumping to file). This is pretty slow - about 6min for 13gb file. Can anyone tell me how to optimize this or if there is a faster way to do this in python ? Thanks! Here is my code: def cat_files_sam(final_file_name,work_directory_master,file_count): final_file = open(final_file_name,"w") if len(file_count) > 1: file_count=sort_output_files(file_count) # only for @ headers for bowtie_file in file_count: #print bowtie_file tmp_list = [] tmp_count = 0 for line in open(os.path.join(work_directory_master,bowtie_file)): if line.startswith("@"): if tmp_count == 1000000: final_file.writelines(tmp_list) tmp_list = [] tmp_count = 0 tmp_list.append(line) tmp_count += 1 else: final_file.writelines(tmp_list) break for bowtie_file in file_count: #print bowtie_file tmp_list = [] tmp_count = 0 for line in open(os.path.join(work_directory_master,bowtie_file)): if line.startswith("@"): continue if tmp_count == 1000000: final_file.writelines(tmp_list) tmp_list = [] tmp_count = 0 tmp_list.append(line) tmp_count += 1 final_file.writelines(tmp_list) final_file.close()

• PC with 2 RAMs of different frequencies (1GB 533MHz + 2GB 667MHz) showing only 2GB RAM

  - by srinivas

  I have 6 years old PC with 1.25GB (1GB + 256MB) of DDR2 533MHz RAM. As computer has become very slow and memory usage reaching its limits most of the times, i decided to upgrade RAM. But unfortunately, im not finding retailers selling DDR2 533Mhz RAM near my area. Since I was not sure mixing up RAMs of different frequencies, i searched in web. Most results said they can be mixed but computer would run at lower frequency of the 2 RAMs. So I bought 2GB DDR2 667Mhz RAM expecting my pc to have 3GB RAM running at 533 MHz. But computer properties page shows only 2GB RAM. BIOS settings too show the slot with 2GB 667MHz as ACTIVE and other slot with 1GB 533MHz as "NOT INSTALLED". When I removed 2GB RAM, they computer shows only 1GB RAM. So for some reason, 1GB RAM is not getting detected/used. What is the problem here? thanks in advance.

• Reverse lookup of inode/file from offset in raw device on linux and ext3/4?

  - by lilinjn

  In linux, given an offset into a raw disk device, is it possible to map back to an partition + inode? For example, suppose I know that string "xyz" is contained at byte offset 1000000 on /dev/sda: (e.g. xxd -l 100 -s 1000000 /dev/sda shows a dump that begins with "xyz") 1) How do I figure out which partition (if any) offset 1000000 is located in?(I imagine this is easy, but am including it for completeness) 2) Assuming the offset is located in a partition, how do I go about finding which inode it belongs to (or determine that it is part of free space) ? Presumably this is filesystem specific, in which case does any one know how to do this for ext4 and ext3?

• I have a WPF/Silverlight ListView whose height is unpredictable and too high. How do I control it be

  - by Rob Perkins

  I have a ListView element with a DataTemplate for each ListViewItem defined as follows. When run, the ListView's height is not collapsed onto the items in the view, which is undesirable behavior: <DataTemplate x:Key="LicenseItemTemplate"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <TextBlock Grid.Row="0" Text="{Binding company}"></TextBlock> <Grid Grid.Row="1" Style="{StaticResource HiddenWhenNotSelectedStyle}"> <Grid.RowDefinitions> <RowDefinition /> </Grid.RowDefinitions> <Button Grid.Row="0">ClickIt</Button> </Grid> </Grid> </DataTemplate> The second row of the outer grid has a style applied which looks like this. The purpose of the style is to : <Style TargetType="{x:Type Grid}" x:Key="HiddenWhenNotSelectedStyle" > <Style.Triggers> <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={ RelativeSource Mode=FindAncestor, AncestorType={x:Type ListViewItem} } }" Value="False"> <Setter Property="Grid.Visibility" Value="Collapsed" /> </DataTrigger> <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={ RelativeSource Mode=FindAncestor, AncestorType={x:Type ListViewItem} } }" Value="True"> <Setter Property="Grid.Visibility" Value="Visible" /> </DataTrigger> </Style.Triggers> </Style> The ListView renders like this: The desired appearance is this, when none of the elements are selected: ...with, of course, the ListView's height adjusting to accommodate the additional content when the second grid is made visible by selection. What can I do to get the desired behavior?

• Django: How can I identify the calling view from a template?

  - by bryan

  Short version: Is there a simple, built-in way to identify the calling view in a Django template, without passing extra context variables? Long (original) version: One of my Django apps has several different views, each with its own named URL pattern, that all render the same template. There's a very small amount of template code that needs to change depending on the called view, too small to be worth the overhead of setting up separate templates for each view, so ideally I need to find a way to identify the calling view in the template. I've tried setting up the views to pass in extra context variables (e.g. "view_name") to identify the calling view, and I've also tried using {% ifequal request.path "/some/path/" %} comparisons, but neither of these solutions seems particularly elegant. Is there a better way to identify the calling view from the template? Is there a way to access to the view's name, or the name of the URL pattern? Update 1: Regarding the comment that this is simply a case of me misunderstanding MVC, I understand MVC, but Django's not really an MVC framework. I believe the way my app is set up is consistent with Django's take on MVC: the views describe which data is presented, and the templates describe how the data is presented. It just happens that I have a number of views that prepare different data, but that all use the same template because the data is presented the same way for all the views. I'm just looking for a simple way to identify the calling view from the template, if this exists. Update 2: Thanks for all the answers. I think the question is being overthought -- as mentioned in my original question, I've already considered and tried all of the suggested solutions -- so I've distilled it down to a "short version" now at the top of the question. And right now it seems that if someone were to simply post "No", it'd be the most correct answer :) Update 3: Carl Meyer posted "No" :) Thanks again, everyone.

  I'm trying to change the resolution on my base shell (the Ctrl+Alt+1) shell in Debian so that it supports my ViewSonic monitor. The shell appears really fuzzy when it is displayed on my lcd monitor, but GRUB looks fine when it's displayed. In I tried changing part of the GRUB_CMDLINE_LINUX_DEFAULT to 'vga=ask', and now I get the error on booting up 'Legacy 'ask' parameter no longer supported' Has this 'vga=ask' value been changed to something else? Note, I tried setting it to 'vga=782' after finding a list of screen modes here and the shell font got real huge for a few seconds during boot up, and then switched back to it's awful fuzzy self again, when I went to use the Debian Bash shell. UPDATE Tried suggestion in this question, it works without fuzziness until the last resolution change which displays the user login to the shell.

• What is a Windows text editor that will make it easy for me to have four text files open onscreen at once?

  - by Ascendant

  When brainstorming / planning I like to have four text files open onscreen at once: One for notes/stream of consciousness, one for action items to follow up on, one for a rough outline, etc.... What I'm looking for is an easy way to create / save four text files in this manner in Windows. Most importantly, I need the lines to wrap based on the width of the actual window itself. Not based on a ruler or document size (a la Word or WordPad) and not wrapping "manually only" (like Windows' built in Notepad application.) Also, I need the windows to have no, or at least, little, fluff at the top of each document (menubars, ribbons, etc.) On my Mac, I've found that the built-in TextEdit application is almost perfect for this. There's no header or ribbon taking up space for each document, and lines wrap when they hit the end of the window. I haven't had any luck finding a Windows application that works the same way.
