• Windows 7, file properties - Is "date accessed" ALWAYS 100% accurate?

  - by Robert

  Hello, Here's the situation: I went on vacation for a couple of weeks, but before I left, I took the harddrive out of my computer and hid it in a different location. Upon coming back on Monday and putting the harddrive back in my computer, I right-clicked on different files to see their properties. Interestingly enough, several files had been accessed during the time I was gone! I right-clicked different files in various locations on the harddrive, and all of these suspect files had been accessed within a certain time range (Sunday, ?January ?09, ?2011, approximately ??between 6:52:16 PM - 7:16:25 PM). Some of them had been accessed at the exact same time--down to the very second. This makes me think that someone must have done a search on my harddrive for certain types of files and then copied all those files to some other medium. The Windows 7 installation on this harddrive is password protected, but NOT encrypted, so they could have easily put the harddrive into an enclosure/toaster to access it from a different computer. Of course I did not right-click every single file on my computer, but did so in different folders. For instance, one of the folders I went through has different types of files: .mp3, ,prproj, .3gp, .mpg, .wmv, .xmp, .txt with file-sizes ranging from 2 KB to 29.7 MB (there is also a sub-folder in this folder which contains only .jpg files); however, of all these different types of files in this folder and its subfolder, all of them had been accessed (including the .jpg files from the sub-folder) EXCEPT the .mp3 files (if it makes any difference, the .mp3 files in this folder range in size from 187 KB to 4881 KB). Additionally, this sub-folder which contained only .jpg files (48 .jpg files to be exact) was not accessed during this time--only the .jpg files within it were accessed-- (between 6:57:03 PM - 6:57:08 PM). I thought that perhaps this was some kind of Windows glitch that was displaying the wrong access date, but then I looked at the "date created" and "date modified" for all of these files in question, and their created/modified dates and times were spot on correct. My first thought was that someone put the harddrive into an enclosure/toaster and viewed the files; but then I realized that this was impossible because several of the files had been accessed at the same exact time down to the second. So this made me think that the only other way the "date accessed" could have changed would have been if someone copied the files. Is there any chance at all whatsoever that this is some kind of Windows glitch or something, or is it a fact that someone was indeed accessing my files (and if someone was accessing my files, am I right about the files in question having been copied)? Is there any other possibility for what could have happened? Do I need to use any kinds of forensics tools to further investigate this matter (and if so, which tools), or is there any other way in which I can be certain of what took place in that timeframe the day before I got back? Or is what I see with Windows 7 good enough (i.e. accurate and truthful)? Thanks in advance, and please let me know if any other details are required on my part.

• dropbox slow on ubuntu 14.04

  My dropbox syncing is incredibly slow... I am using dropbox from the ubuntu repository on an almost fresh ubuntu installation. I would like to avoid to install the package from the dropbox website for the reasons explained here Dropbox Upgrade Is someone having the same problem? How can I solve? EDIT : This is an example of what I get. donbeo@donbeo-HP-EliteBook-Folio-9470m:~$ dropbox status Syncing (17 files remaining, 22 secs left) Uploading 17 files (123.3 KB/sec, 22 secs left) donbeo@donbeo-HP-EliteBook-Folio-9470m:~$ dropbox status Syncing (17 files remaining, 3 mins left) Uploading 17 files (13.2 KB/sec, 3 mins left) donbeo@donbeo-HP-EliteBook-Folio-9470m:~$ dropbox status Syncing (17 files remaining, 5 mins left) Uploading 17 files (8.2 KB/sec, 5 mins left) donbeo@donbeo-HP-EliteBook-Folio-9470m:~$ dropbox status Syncing (17 files remaining) Uploading 17 files... donbeo@donbeo-HP-EliteBook-Folio-9470m:~$ dropbox status Syncing (17 files remaining) Uploading 17 files... donbeo@donbeo-HP-EliteBook-Folio-9470m:~$ EDIT: I have run sudo dropbox update so I am probably using the last version of dropbox

• New Bundling and Minification Support (ASP.NET 4.5 Series)

  - by ScottGu

  This is the sixth in a series of blog posts I'm doing on ASP.NET 4.5. The next release of .NET and Visual Studio include a ton of great new features and capabilities.  With ASP.NET 4.5 you'll see a bunch of really nice improvements with both Web Forms and MVC - as well as in the core ASP.NET base foundation that both are built upon. Today’s post covers some of the work we are doing to add built-in support for bundling and minification into ASP.NET - which makes it easy to improve the performance of applications.  This feature can be used by all ASP.NET applications, including both ASP.NET MVC and ASP.NET Web Forms solutions. Basics of Bundling and Minification As more and more people use mobile devices to surf the web, it is becoming increasingly important that the websites and apps we build perform well with them. We’ve all tried loading sites on our smartphones – only to eventually give up in frustration as it loads slowly over a slow cellular network.  If your site/app loads slowly like that, you are likely losing potential customers because of bad performance.  Even with powerful desktop machines, the load time of your site and perceived performance can make an enormous customer perception. Most websites today are made up of multiple JavaScript and CSS files to separate the concerns and keep the code base tight. While this is a good practice from a coding point of view, it often has some unfortunate consequences for the overall performance of the website.  Multiple JavaScript and CSS files require multiple HTTP requests from a browser – which in turn can slow down the performance load time.  Simple Example Below I’ve opened a local website in IE9 and recorded the network traffic using IE’s built-in F12 developer tools. As shown below, the website consists of 5 CSS and 4 JavaScript files which the browser has to download. Each file is currently requested separately by the browser and returned by the server, and the process can take a significant amount of time proportional to the number of files in question. Bundling ASP.NET is adding a feature that makes it easy to “bundle” or “combine” multiple CSS and JavaScript files into fewer HTTP requests. This causes the browser to request a lot fewer files and in turn reduces the time it takes to fetch them.   Below is an updated version of the above sample that takes advantage of this new bundling functionality (making only one request for the JavaScript and one request for the CSS): The browser now has to send fewer requests to the server. The content of the individual files have been bundled/combined into the same response, but the content of the files remains the same - so the overall file size is exactly the same as before the bundling.   But notice how even on a local dev machine (where the network latency between the browser and server is minimal), the act of bundling the CSS and JavaScript files together still manages to reduce the overall page load time by almost 20%.  Over a slow network the performance improvement would be even better. Minification The next release of ASP.NET is also adding a new feature that makes it easy to reduce or “minify” the download size of the content as well.  This is a process that removes whitespace, comments and other unneeded characters from both CSS and JavaScript. The result is smaller files, which will download and load in a browser faster.  The graph below shows the performance gain we are seeing when both bundling and minification are used together: Even on my local dev box (where the network latency is minimal), we now have a 40% performance improvement from where we originally started.  On slow networks (and especially with international customers), the gains would be even more significant. Using Bundling and Minification inside ASP.NET The upcoming release of ASP.NET makes it really easy to take advantage of bundling and minification within projects and see performance gains like in the scenario above. The way it does this allows you to avoid having to run custom tools as part of your build process –  instead ASP.NET has added runtime support to perform the bundling/minification for you dynamically (caching the results to make sure perf is great).  This enables a really clean development experience and makes it super easy to start to take advantage of these new features. Let’s assume that we have a simple project that has 4 JavaScript files and 6 CSS files: Bundling and Minifying the .css files Let’s say you wanted to reference all of the stylesheets in the “Styles” folder above on a page.  Today you’d have to add multiple CSS references to get all of them – which would translate into 6 separate HTTP requests: The new bundling/minification feature now allows you to instead bundle and minify all of the .css files in the Styles folder – simply by sending a URL request to the folder (in this case “styles”) with an appended “/css” path after it.  For example:    This will cause ASP.NET to scan the directory, bundle and minify the .css files within it, and send back a single HTTP response with all of the CSS content to the browser.  You don’t need to run any tools or pre-processor to get this behavior.  This enables you to cleanly separate your CSS into separate logical .css files and maintain a very clean development experience – while not taking a performance hit at runtime for doing so.  The Visual Studio designer will also honor the new bundling/minification logic as well – so you’ll still get a WYSWIYG designer experience inside VS as well. Bundling and Minifying the JavaScript files Like the CSS approach above, if we wanted to bundle and minify all of our JavaScript into a single response we could send a URL request to the folder (in this case “scripts”) with an appended “/js” path after it:   This will cause ASP.NET to scan the directory, bundle and minify the .js files within it, and send back a single HTTP response with all of the JavaScript content to the browser.  Again – no custom tools or builds steps were required in order to get this behavior.  And it works with all browsers. Ordering of Files within a Bundle By default, when files are bundled by ASP.NET they are sorted alphabetically first, just like they are shown in Solution Explorer. Then they are automatically shifted around so that known libraries and their custom extensions such as jQuery, MooTools and Dojo are loaded before anything else. So the default order for the merged bundling of the Scripts folder as shown above will be: Jquery-1.6.2.js Jquery-ui.js Jquery.tools.js a.js By default, CSS files are also sorted alphabetically and then shifted around so that reset.css and normalize.css (if they are there) will go before any other file. So the default sorting of the bundling of the Styles folder as shown above will be: reset.css content.css forms.css globals.css menu.css styles.css The sorting is fully customizable, though, and can easily be changed to accommodate most use cases and any common naming pattern you prefer.  The goal with the out of the box experience, though, is to have smart defaults that you can just use and be successful with. Any number of directories/sub-directories supported In the example above we just had a single “Scripts” and “Styles” folder for our application.  This works for some application types (e.g. single page applications).  Often, though, you’ll want to have multiple CSS/JS bundles within your application – for example: a “common” bundle that has core JS and CSS files that all pages use, and then page specific or section specific files that are not used globally. You can use the bundling/minification support across any number of directories or sub-directories in your project – this makes it easy to structure your code so as to maximize the bunding/minification benefits.  Each directory by default can be accessed as a separate URL addressable bundle.  Bundling/Minification Extensibility ASP.NET’s bundling and minification support is built with extensibility in mind and every part of the process can be extended or replaced. Custom Rules In addition to enabling the out of the box - directory-based - bundling approach, ASP.NET also supports the ability to register custom bundles using a new programmatic API we are exposing.  The below code demonstrates how you can register a “customscript” bundle using code within an application’s Global.asax class.  The API allows you to add/remove/filter files that go into the bundle on a very granular level:     The above custom bundle can then be referenced anywhere within the application using the below <script> reference:     Custom Processing You can also override the default CSS and JavaScript bundles to support your own custom processing of the bundled files (for example: custom minification rules, support for Saas, LESS or Coffeescript syntax, etc). In the example below we are indicating that we want to replace the built-in minification transforms with a custom MyJsTransform and MyCssTransform class. They both subclass the CSS and JavaScript minifier respectively and can add extra functionality:     The end result of this extensibility is that you can plug-into the bundling/minification logic at a deep level and do some pretty cool things with it. 2 Minute Video of Bundling and Minification in Action Mads Kristensen has a great 90 second video that shows off using the new Bundling and Minification feature.  You can watch the 90 second video here. Summary The new bundling and minification support within the next release of ASP.NET will make it easier to build fast web applications.  It is really easy to use, and doesn’t require major changes to your existing dev workflow.  It is also supports a rich extensibility API that enables you to customize it however you want. You can easily take advantage of this new support within ASP.NET MVC, ASP.NET Web Forms and ASP.NET Web Pages based applications. Hope this helps, Scott P.S.

  We need to redirect the logs from our Cisco firewall(SA520-K9) to syslogd server(it's a CentOS server). The settings are done on the firewall. But the messages from firewall are going to /var/log/messages and console instead of /var/log/firewall.log which is our requirent. *.info;mail.none;authpriv.none;cron.none /var/log/messages authpriv.* /var/log/secure mail.* -/var/log/maillog cron.* /var/log/cron *.emerg * uucp,news.crit /var/log/spooler local7.* /var/log/firewall.log This is our syslog config file. Any advices ?

• Is it a bad practice to store large files (10 MB) in a database?

  - by B Seven

  I am currently creating a web application that allows users to store and share files, 1 MB - 10 MB in size. It seems to me that storing the files in a database will significantly slow down database access. Is this a valid concern? Is it better to store the files in the file system and save the file name and path in the database? Are there any best practices related to storing files when working with a database? I am working in PHP and MySQL for this project, but is the issue the same for most environments (Ruby on Rails, PHP, .NET) and databases (MySQL, PostgreSQL).

• MVC Portable Areas &ndash; Static Files as Embedded Resources

  - by Steve Michelotti

  This is the third post in a series related to build and deployment considerations as I’ve been exploring MVC Portable Areas: #1 – Using Web Application Project to build portable areas #2 – Conventions for deploying portable area static files #3 – Portable area static files as embedded resources In the last post, I walked through a convention for managing static files.  In this post I’ll discuss another approach to manage static files (e.g., images, css, js, etc.).  With this approach, you *also* compile the static files as embedded resources into the assembly similar to the *.aspx pages. Once again, you can set this to happen automatically by simply modifying your *.csproj file to include the desired extensions so you don’t have to remember every time you add a file: 1: <Target Name="BeforeBuild"> 2: <ItemGroup> 3: <EmbeddedResource Include="**\*.aspx;**\*.ascx;**\*.gif;**\*.css;**\*.js" /> 4: </ItemGroup> 5: </Target> We now need a reliable way to serve up these static files that are embedded in the assembly. There are a couple of ways to do this but one way is to simply create a Resource controller whose job is dedicated to doing this. 1: public class ResourceController : Controller 2: { 3: public ActionResult Index(string resourceName) 4: { 5: var contentType = GetContentType(resourceName); 6: var resourceStream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName); 7:   8: return this.File(resourceStream, contentType); 9: return View(); 10: } 11:   12: private static string GetContentType(string resourceName) 13: { 14: var extention = resourceName.Substring(resourceName.LastIndexOf('.')).ToLower(); 15: switch (extention) 16: { 17: case ".gif": 18: return "image/gif"; 19: case ".js": 20: return "text/javascript"; 21: case ".css": 22: return "text/css"; 23: default: 24: return "text/html"; 25: } 26: } 27: } In order to use this controller, we need to make sure we’ve registered the route in our portable area registration (shown in lines 5-6): 1: public class WidgetAreaRegistration : PortableAreaRegistration 2: { 3: public override void RegisterArea(System.Web.Mvc.AreaRegistrationContext context, IApplicationBus bus) 4: { 5: context.MapRoute("ResourceRoute", "widget1/resource/{resourceName}", 6: new { controller = "Resource", action = "Index" }); 7:   8: context.MapRoute("Widget1", "widget1/{controller}/{action}", new 9: { 10: controller = "Home", 11: action = "Index" 12: }); 13:   14: RegisterTheViewsInTheEmbeddedViewEngine(GetType()); 15: } 16:   17: public override string AreaName 18: { 19: get { return "Widget1"; } 20: } 21: } In my previous post, we relied on a custom Url helper method to find the actual physical path to the static file like this: 1: <img src="<%: Url.AreaContent("/images/arrow.gif") %>" /> Hello World! However, since we are now embedding the files inside the assembly, we no longer have to worry about the physical path. We can change this line of code to this: 1: <img src="<%: Url.Resource("Widget1.images.arrow.gif") %>" /> Hello World! Note that I had to fully quality the resource name (with namespace and physical location) since that is how .NET assemblies store embedded resources. I also created my own Url helper method called Resource which looks like this: 1: public static string Resource(this UrlHelper urlHelper, string resourceName) 2: { 3: var areaName = (string)urlHelper.RequestContext.RouteData.DataTokens["area"]; 4: return urlHelper.Action("Index", "Resource", new { resourceName = resourceName, area = areaName }); 5: } This method gives us the convenience of not having to know how to construct the URL – but just allowing us to refer to the resource name. The resulting html for the image tag is: 1: <img src="/widget1/resource/Widget1.images.arrow.gif" /> so we can always request any image from the browser directly. This is almost analogous to the WebResource.axd file but for MVC. What is interesting though is that we can encapsulate each one of these so that each area can have it’s own set of resources and they are easily distinguished because the area name is the first segment of the route. This makes me wonder if something like this ResourceController should be baked into portable areas itself. I’m definitely interested in anyone has any opinions on it or have taken alternative approaches.

• How can I associate .doc files to MS Word 2010 using the same .desktop file as launcher?

  - by nastys

  I'm trying to associate .doc and .docx files to MS Word 2010 using the same .desktop file as Unity dash and launcher, so I can use the Word icon in launcher. I tried: [Desktop Entry] Name=Microsoft Word 2010 Exec=env WINEPREFIX="/home/nastys/.mso2010" wine "C:/Program Files/Microsoft Office/Office14/WINWORD.exe" %f Type=Application StartupNotify=true Comment=Create and edit professional-looking documents such as letters, papers, reports, and booklets by using Microsoft Word. Icon=29F5_WINWORD.0 StartupWMClass=WINWORD.EXE MimeType=application/msword; application/vnd.openxmlformats-officedocument.wordprocessingml.document; Using this .desktop file I can launch Word with its icon in Unity launcher, but if I associate .doc files to the same file Word will launch, but it won't open the .doc file. If I associate .doc files to any .desktop file generated by Wine it will launch Word, but it will use Wine icon.

• Symbolic link all files in directory to show in another directory?

  - by Thomas Clayson

  What I want is to be able to display all files that are ftp'd into /home/ftp in /srv/ftp /srv/ftp is password protected, and has files in it which I don't want to be accessible from the public ftp. So as such I wish that all files uploaded to /home/ftp are automatically symbolically linked (or otherwise) to /srv/ftp. Does this make sense? e.g. ls /srv/ftp: file.sh another.txt something_else.i386 then a user ftp's and drops a file in /home/ftp (or ssh, or whatever) ls /home/ftp: user_file.mk ls /srv/ftp: file.sh another.txt something_else.i386 user_file.mk I hope this makes sense. I have been told that this can probably be achieved using ln to create symbolic links, but I don't want to have to ssh in and create the links every time I (or someone else) puts files over ftp. Thanks! :)

• Making files generally available on Linux system (when security is relatively unimportant)?

  - by Ole Thomsen Buus

  Hi, I am using Ubuntu 9.10 on a stationary PC. I have a secondary 1 TB harddrive with a single big logical partition (currently formatted as ext4). It is mounted as /usr3 with options user, exec in /etc/fstab. I am doing highspeed imaging experiments. Well, only 260fps, but that still creates many individual files since each frames is saved as one png-file. The stationary is not used by anyone other than me which is why the default security model posed by ubuntu is not necessary. What is the best way to make the entire contents of /usr3 generally available on all systems. In case I need to move the harddrive to another Ubuntu 9.x or 10.x machine? When grabbing image with the firewire camera I use a selfmade grabbing software-utility (console based) in sudo-mode. This creates all files with root as owner and group. I am logged in as user otb and usually I do the following when having to make files generally available to otb: sudo chown otb -R * sudo chgrp otb -R * sudo chmod a=rwx -R * This takes some time since the disk now contains individual ~200000 files. After this, how would linux behave if I moved the harddrive to another system where the user otb is also available? Would the files still be accessible without sudo use?

• How can I keep directories in sync

  - by Guillaume Boudreau

  I have a directory, dirA, that users can work in: they can create, modify, rename and delete files & sub-directores in dirA. I want to keep another directory, dirB, in sync with dirA. What I'd like, is a discussion on finding a working algorithm that would achieve the above, with the limitations listed below. Requirements: 1. Something asynchronous - I don't want to stop file operations in dirA while I work in dirB. 2. I can't assume that I can just blindly rsync dirA to dirB on regular interval - dirA could contain millions of files & directories, and terrabytes of data. Completely walking the dirA tree could take hours. Those two requirements makes this really difficult. Having it asynchronous means that when I start working on a specific file from dirA, it might have moved a lot since it appeared. And the second limitation means that I really need to watch dirA, and work on atomic file operations that I notice. Current (broken) implementation: 1. Log all file & directory operations in dirA. 2. Using a separate process, read that log, and 'repeat' all the logged operations in dirB. Why is it broken: echo 1 > dirA/file1 # Allow the 'log reader' process to create dirB/file1: log = "write dirA/file1"; action = cp dirA/file1 dirB/file1; result = OK echo 1 > dirA/file2 mv dirA/file1 dirA/file3 mv dirA/file2 dirA/file1 rm dirA/file3 # End result: file1 contains '1' # 'log reader' process starts working on the 4 above file operations: log = "write file2"; action = cp dirA/file2 dirB/file2; result = failed: there is no dirA/file2 log = "rename file1 file3"; action = mv dirB/file1 dirB/file3; result = OK log = "rename file2 file1"; action = mv dirB/file2 dirB/file1; result = failed: there is no dirB/file2 log = "delete file3"; action = rm dirB/file3; result = OK # End result in dirB: no more files! Another broken example: echo 1 > dirA/dir1/file1 mv dirA/dir1 dirA/dir2 # 'log reader' process starts working on the 2 above file operations: log = "write file1"; action = cp dirA/dir1/file1 dirB/dir1/file1; result = failed: there is no dirA/dir1/file1 log = "rename dir1 dir2"; action = mv dirB/dir1 dirB/dir2; result = failed: there is no dirA/dir1 # End result if dirB: nothing!

• No Visual studio template information found. See application log in Event viewer for more details

  - by sathya

  I tried installing the .NET Framework 4.0 and ASP.NET MVC 2 Framework through the web platform installer. It took a long time and finally i had a restart in between for .NET 4 installation and after that due to my system hang problems had to do a couple of restarts. And after that tried installing the ASP.NET MVC 2 alone and it succeeded. (During this time i had all my VS instances closed).  I am having VS 2008 SP1. And finally after opening VS 2008 and clicking on new project it said the above error no template info found. and i dint have even a single template in the new project template selection window. So these are the steps that i did for recovering the same.  Start Menu --> Microsoft Visual Studio 2008 --> Visual Studio Tools. Right-click over the Visual Studio Command Prompt shortcut and make sure you select Run as Administrator. Once the VS Command Prompt comes up, execute the command 1. "devenv /installvstemplates" 2. "devenv /resetsettings"  And that worked out. No Visual studio template information found. See application log in Event viewer for more detail

• How to verify that all files are intact prior to install?

  - by Kalle H. Väravas

  I'm working on my CMS (in PHP platform) for a long time now. The main program is done and I'm currently developing the Installer part. Installation itself will be fairly simple: Upload all files Verify that the "content/" dir has correct permissions Check if ALL files are intact and not modified [This is the subject of this question] Insert the config data and first settings Run install (Generate all DB tables and insert sample data etc.) Now the question-mark is at step 3. How do I verify ALL files? Verification itself should compare all CMS root-directories files against a list from remote location. List should contain filename, filesize and filetype. This way the user can check, that there are no unnecessary or corrupted files, that could indicated a breach in the software. I have seen some software installers do that, but I cannot find any right now and there for I'm clueless on the most optimal method for this. Of course there always is a simple array trick, but there surely must be a better and faster method?!

• Is there now any way to convert mp3 files to m4a or aac 192kbit?

  - by piedro

  Since about two years now I am trying to find a way to convert high quality mp3 files to m4a or aac files with a fixed bitrate 192k. Please don't suggest using another format - i thought this through as far as it goes. The problem here is: ffmpeg obvioulsy can't convert to a higher bitrate than 152k. Even when it says it does so the resulting files still have 152k instead of 192k. ffmpeg also has/had a bug not writing the bitrate into the audio file tags which means when testing you have to calculate the bitrate manually by dividing the filesize by the length of the audio in seconds (resulting in 152k - see above) choosing faac as converter gets me the same results other programs don't work reliably (see this thread Howto convert audio files to *.m4a? I know that this is not an original new problem but I am wondering if there is still no way to convert with ubuntu/kubuntu 12.04 after a lot time passed and I can't find some of the bug issues mentioned in the other thread anymore. So: Is there a solution after all?

• How can I create a zip archive of a whole directory via terminal without hidden files?

  I have a project with lots of hidden folders / files in it. I want to create a zip-archive of it, but in the archive shouldn't be any hidden folders / files. If files in a hidden folder are not hidden, they should also not be included. I know that I can create a zip archive of a directory like this: zip -r zipfile.zip directory I also know that I can exclude files with the -x option, so I thought this might work: zip -r zipfile.zip directory -x .* It didn't work. All hidden directories were still in the zip-file.

• What are the files in /dev/input/ and what they do?

  - by Pouya

  I'm fairly new to ubuntu and I've started to search around everywhere and check everything! Recently I saw these files at /dev/input/eventX, js0, mice, mouseX. By printing the output using "cat" I realized they are somehow responsible for mouse and keyboard input but the output had an strange character encoding (even for the keyboard). My questions are, what are these files and how can I interpret the data of these files? Are there any other places that I can access the input/output of my Ubuntu machine? And are there any ebooks, manual or something similar that I can check the duty and structure of ubuntu system files? (i.e. to find the answer of such question)

• My ubuntu server is losing connectivity, require assistance troubleshooting

  - by Coderama

  I have two server monitoring tools that check the uptime of my Ubuntu 10.04.1 LTS server. Over the last month both of these tools have reported the following outages: Jan - 15mins: self recovery Jan - 5 mins: self recovery Feb - 15mins: I managed to be online when this happened and logged into my control panel to find that my server was shutdown. I manually restarted it only because I was online. I wonder if it would have restarted? I have contacted my VPS provider (webbynode) who could not see any any problems with their VPS infrastructure for the February outage. I have also checked the following log files to see if there are any anomalies that could be the cause of the outages; I am unable to see anything related to the server shutdown (Feb) in these logs: /var/log/auth.log /var/log/apache2/error.log /var/log/syslog /var/log/kern.log /var/log/boot /var/log/messages Could anyone suggest any other things I should look out for, such as additional system logs? I just added bootlogging through /etc/default/bootlogd

• Prevent Nautilus from generating thumbnails for video files larger than 5 MB?

  - by Lisa

  If I set in Nautilus preferences that it should generate thumbnail previews only for files larger than 10 MB, then this only works for pictures. Nautilus still keeps generating thumbnails for videos and pdf files. Even if a video file is 500 MB. It should only generate thumbnails for video files less than 10 MB as set in the preferences. Same goes for pdf. I have many pdf files that are larger than 50 MB. I don't want Nautilus to generate thumbnails for these, only for small sized pdf. How can I make Nautilus to obey the Previews preferences? Nautilus 3.4.2 Ubuntu 12.04.1, 64bit

• 500 Error on index.php file. All other php files are working well

  - by Stas

  I've successfully installed LAMP and created some virtual hosts. Everything is working fine except index.php files. When I try access them, browser returns 500 Error, regardless of their content. All other PHP files are working fine, index.html files can be opened without any errors. Please, help me to resolve this problem. I guess something wrong with server configuration, but I didn't find what exactly.

• How can I prevent people from looking at a listing of files in parent directory if I haven't uploaded index.html? [closed]

  - by LedZeppelin

  Possible Duplicate: How to restrict the download of all files in a folder? I haven't uploaded index.html or index.php to my root directory. How can I prevent people from looking at a listing of files in parent directory? http://oi56.tinypic.com/sc739e.jpg Also, is it possible for people to obtain a list of all the files in the root directory once I upload index.html? I'm currently using .htaccess and htusers to prompt someone to enter a username and password when they try to access any file in the root directory. This may sound like a weird request but would it be possible to have them come to the site (without an index.html) and just have them not see the files? All it would say on the page would be the following: Index of/ Apache Server at mysite.com Port 80

• How do I use Content.Load() with raw XML files?

  - by xnanewb

  I'm using the Content.Load() mechanism to load core game definitions from XML files. It works fine, though some definitions should be editable/moddable by the players. Since the content pipeline compiles everything into xnb files, that doesn't work for now. I've seen that the inbuild XNA Song content processor does create 2 files. 1 xnb file which contains meta data for the song and 1 wma file which contains the actual data. I've tried to rebuild that mechanism (so that the second file is the actual xml file), but for some reason I can't use the namespace which contains the IntermediateSerializer class to load the xml (obviously the namespace is only available in a content project?). How can I deploy raw, editable xml files and load them with Content.Load()?

• How to structure my java packages

  - by MightyPork

  I have a Java library, quite a huge one. I'm asking regarding Best Practices of structuring the source. For example, the logging sybsystem: Option 1: All in one package, named to sort nicely Log - static accessor LogMonitor - interface for log minotor LogMonitorBase - abstract class LogMonitorStdout - print log to console LogWriter - interface for file logger LogWriterSimple - log writer with just one log file LogWriterArchiving - log writer that handles old log files Option 2: Subpackages for Monitors and Writers, with better names Log monitors/LogMonitor monitors/BaseMonitor monitors/StdoutMonitor writers/LogWriter writers/SimpleLog writers/ArchivingLog The second maybe looks better, but perhaps it's not so practical from the java point of view (two extra packages). What do you suggest as the best practice here? A lot in one package, grouped by naming prefixes, or a lot of subpackages with better names?

• ADF Logging In Deployed Apps

  - by Duncan Mills

  Harking back to my series on using the ADF logger and the related  ADF Insider Video, I've had a couple of queries this week about using the logger from Enterprise Manager (EM). I've alluded in those previous materials to how EM can be used but it's evident that folks need a little help.  So in this article, I'll quickly look at how you can switch logging on from the EM console for an application and how you can view the output.  Before we start I'm assuming that you have EM up and running, in my case I have a small test install of Fusion Middleware Patchset 5 with an ADF application deployed to a managed server. Step 1 - Select your Application In the EM navigator select the app you're interested in: At this point you can actually bring up the context ( right mouse click) menu to jump to the logging, but let's do it another way.  Step 2 - Open the Application Deployment Menu At the top of the screen, underneath the application name, you'll find a drop down menu which will take you to the options to view log messages and configure logging, thus: Step 3 - Set your Logging Levels  Just like the log configuration within JDeveloper, we can set up transient or permanent (not recommended!) loggers here. In this case I've filtered the class list down to just oracle.demo, and set the log level to config. You can now go away and do stuff in the app to generate log entries. Step 4 - View the Output  Again from the Application Deployment menu we can jump to the log viewer screen and, as I have here, start to filter down the logging output to the stuff you're interested in.  In this case I've filtered by module name. You'll notice here that you can again look at related log messages. Importantly, you'll also see the name of the log file that holds this message, so it you'd rather analyse the log in more detail offline, through the ODL log analyser in JDeveloper, then you can see which log to download.

• Ubuntu freezes while working

  - by webid4me

  Ubuntu on my laptop has frozen multiple times in last 6-7 months. Its not frequent but I can not relate the freezing to anything which I was doing. Today it froze again when I was taking notes in class - approximately at 12:00 PM. During the freeze both mouse and keyboard stopped working. I tried Alt-Ctrl-F1, Alt-Ctrl-F2 etc without any success. After that I waited few minutes & then I restarted the laptop. I checked /var/log/syslog and /var/log/kern.log and it seems that it did not log anything (I was not able to understand most of it). Please let me know if you can find something unusual at around 12:00 PM. Is there any other log which might be useful? Here are the /var/log/syslog and /var/log/kern.log files.
