• Recording slow web stream

  - by Budric

  I'm trying to record an mpeg2 video stream from a website that doesn't have the greatest bandwidth. The video often buffers. I want to download the stream and watch it offline. The extract stream format received is: Stream #0.0[0x44]: Audio: mp2, 48000 Hz, stereo, s16, 192 kb/s Stream #0.1[0x45]: Video: mpeg2video (Main), yuv420p, 704x576 [PAR 16:11 DAR 16:9], 15000 kb/s, 27.19 fps, 25 tbr, 90k tbn, 50 tbc I use the following tool to transocde the stream: ffmpeg -i "http://url" -y -vcodec libx264 -b 3000k -acodec copy /tmp/stream.mp4 Unfortunately after a few seconds ffmpeg stops recording with an error [mpegts @ 0x1f0b9c0] PES packet size mismatch [mp2 @ 0x1f14640] incomplete frame Error while decoding stream #0.0 [mpeg2video @ 0x1f16860] ac-tex damaged at 0 26 [mpeg2video @ 0x1f16860] Warning MVs not available I've tried encoding with vlc as well with similar issues.

Anyone know what's wrong or how to fix this?

• What's the best practice to do SOA exception handling?

  - by sun1991

  Here's some interesting debate going on between me and my colleague when coming to handle SOA exceptions: On one side, I support what Juval Lowy said in Programming WCF Services 3rd Edition: As stated at the beginning of this chapter, it is a common illusion that clients care about errors or have anything meaningful to do when they occur. Any attempt to bake such capabilities into the client creates an inordinate degree of coupling between the client and the object, raising serious design questions. How could the client possibly know more about the error than the service, unless it is tightly coupled to it? What if the error originated several layers below the service—should the client be coupled to those lowlevel layers? Should the client try the call again? How often and how frequently? Should the client inform the user of the error? Is there a user? By having all service exceptions be indistinguishable from one another, WCF decouples the client from the service. The less the client knows about what happened on the service side, the more decoupled the interaction will be. On the other side, here's what my colleague suggest: I believe it’s simply incorrect, as it does not align with best practices in building a service oriented architecture and it ignores the general idea that there are problems that users are able to recover from, such as not keying a value correctly. If we considered only systems exceptions, perhaps this idea holds, but systems exceptions are only part of the exception domain. User recoverable exceptions are the other part of the domain and are likely to happen on a regular basis. I believe the correct way to build a service oriented architecture is to map user recoverable situations to checked exceptions, then to marshall each checked exception back to the client as a unique exception that client application programmers are able to handle appropriately. Marshall all runtime exceptions back to the client as a system exception, along with the stack trace so that it is easy to troubleshoot the root cause. I'd like to know what you think about this? Thank you.

• Why do I get "permission denied" errors with Python easy_install?

  - by ATMathew

  I'm an Ubuntu newbie and have been trying to install python's easy_install so that I don't have to deal with source files when install Python libraries. I"ve ran the following, and it seems to install the correct applications: sudo apt-get install python-setuptools However, when i run easy_install sqlalchemy or easy_install pysqlite3, it doesn't work. I get the following error message: install_dir /usr/local/lib/python2.6/dist-packages/ error: can't create or remove files in install directory The following error occurred while trying to add or remove files in the installation directory: [Errno 13] Permission denied: '/usr/local/lib/python2.6/dist-packages/test-easy-install-1674.pth' The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was: /usr/local/lib/python2.6/dist-packages/ Perhaps your account does not have write access to this directory? If the installation directory is a system-owned directory, you may need to sign in as the administrator or "root" account. If you do not have administrative access to this machine, you may wish to choose a different installation directory, preferably one that is listed in your PYTHONPATH environment variable. For information on other options, you may wish to consult the documentation at: http://packages.python.org/distribute/easy_install.html Please make the appropriate changes for your system and try again. Help! Abraham

• Procedure or function has too many arguments specified

  - by bullpit

  This error took me a while to figure out. I was using SqlDataSource with stored procedures for SELECT and UPDATE commands. The SELECT worked fine. Then I added UPDATE command and while trying to update, I would get this error: "Procedure of function has too many arguments specified" Apparently, good guys at .NET decided it is necessary to send SELECT parameters with the UPDATE command as well. So when I was sending the required parameters to the UPDATE sp, in reality, it was also getting my SELECT parameters, and thus failing. I had to add the extra parameters in the UPDATE stored procedure and make them NULLABLE so that they are not required....phew... Here is piece of SP with unused parameters. ALTER PROCEDURE [dbo].[UpdateMaintenanceRecord]        @RecordID INT     ,@District VARCHAR(255)     ,@Location VARCHAR(255)         --UNUSED PARAMETERS     ,@MTBillTo VARCHAR(255) = NULL     ,@SerialNumber VARCHAR(255) = NULL     ,@PartNumber VARCHAR(255) = NULL Update: I was getting that error because unkowingly, I had bound the extra fields in my GridVeiw with Bind() call. I changed all the extra one's, which did not need to be in Update, to Eval() and everything works fine.

• htaccess correct, Apache logs still showing the evil visitors with 200 code

  - by bulgin

  I hope someone can help me. Please take a look at the following snippet of Apache logs: 95-169-172-157.evilvisitor.com - - [12/Nov/2012:09:46:02 -0500] "GET /the-page-I-dont-want-to-deliver.html HTTP/1.1" 200 9171 "http://hackers.ru/" "Mozilla/4.0 (MSIE 6.0; Windows NT 5.1; Search)" I have the following included in my .htaccess for the root directory of the website and there are no other .htaccess files anywhere that would affect this: RewriteEngine On Options +FollowSymLinks ServerSignature Off ErrorDocument 403 "Nothing Interesting Here" order allow,deny deny from evilvisitor.com deny from hackers.ru deny from anonymouse.org allow from all I also have GeoIP functioning properly and have this included there: #for stuff from different countries RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^(UA|TR|RU|RO|LV|CZ|IR|HR|KR|TW|NO|NL|NO|IL|SE) RewriteRule ^(.*)$ [R=F,L I know this works because whenever I attempt to access the website from a proxy in say, Spain, I get the error message. I also know it works because when accessing the website from anonymouse.org, the proper error code page is displayed. So then why am I still getting these visitors who successfully access the page I don't want them to see with an Apache 200 code when it should be an error code?

• Still can't mount windows 8 drive after restart

  - by Ishai Bloch

  After following the instructions in other posts, I am still getting the same error when I try to mount my Windows 8 drive in Ubuntu 14.04 on a dual boot system. I have disabled fast start after shutdown, hybrid hibernation, and the preinstalled Asus Instant On service. I have tried restarting Windows rather than shutting down. In all cases I get the same error message, namely: Error mounting /dev/sda4 at /media/jesse/OS: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda4" "/media/jesse/OS"' exited with non-zero exit status 14: Windows is hibernated, refused to mount. Failed to mount '/dev/sda4': Operation not permitted The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option. I did not have the same issue before upgrading from Ubuntu 12 to 14. For what it's worth my computer is supposedly a "hybrid" with an SSD drive installed, although I can't see that the SSD drive is being used at all with my present settings. Any thoughts?

• Windows 8 Store App Crash Logs

  - by David Paquette

  I was recently working on a Windows 8 app, and the application was crashing occasionally.  When resuming the application, the app would crash and close immediately without providing any feedback or information on what went wrong.  The crash was very difficult to reproduce, and I could never get the crash to occur when I was debugging through Visual Studio.  My app was crashing, and I had no idea what was going wrong!  HELP!!! After doing some digging, I found that when a Windows 8 Store App crashes, an error is logged in Windows Administrative Events.  You can view the details of any app crash by launching the Event Viewer and selecting Administrative Events under Custom Views.  The Source of the error will be listed as AppHost.  AppHost is the process that runs your Windows 8 Store App.  The error details contain all the information you would expect to find, including a stack trace and line numbers.   Windows 8 Tip:  A shortcut for launching the Event Viewer in Windows 8.  Right click on the bottom left corner of your desktop (where you normally click to go to the Start Screen).  A menu will appear with shortcuts to a number of common system tasks such as Event Viewer, Task Manager, Command Prompt, and Device Manager.

• Question about a simple design problem

  - by Uri

  At work I stumbled uppon a method. It made a query, and returned a String based on the result of the query, such as de ID of a customer. If the query didn't return a single customer, it'd return a null. Otherwise, it'd return a String with the ID's of them. It looked like this: String error = getOwners(); if (error != null) { throw new Exception("Can't delete, the flat is owned by: " + error); } ... Ignoring the fact that getCustomers() returns a null when it should instead return an empty String, two things are happening here. It checks if the flat is owned by someone, and then returns them. I think a more readable logic would be to do this: if (isOwned) { throw new Exception("Can't delete, the flat is owned by: " + getOwners()); } ... The problem is that the first way does with one query what I do with two queries to the database. What would be a good solution involving good design and efficiency for this?

• Joomla 1.6 site cannot add a new extension through admin interface

  - by Ghlouw

  I'm having a very frustrating problem with my Joomla 1.6 site. I cannot add any new extensions through the admin interface. I have tried to upload the extension, or to use the search folder option or even the direct link. Neither of these options work, and all that happens is that the page tries to load forever until it finally timesout with a blank white page (no further error messages). I have tried this with multiple browsers (Chrome,FF,IE) and I have tried it with different extensions (modules, components, templates - all the same result). So I don't think it has anything to do with what I am uploading, but more likely the problem is something with the post action. I have also seen the exact same error occur when I try to update menu items or even create new menu items. I am not getting this error with a duplicate of the site in the dev environment, but only get this on my shared web hosting live server. This is on a Windows IIS / PHP / mySQL environment. Any help would be much appreciated!

• Network print to brother MFC-7420

  - by trampster

  I am trying to pint to a Brother MFC-7420 from my ubuntu 10.04 machine. The brother is attached to a windows XP machine and is shared. This is what I have tried: System-Administration-Printing, Add, Expand Network Printer, Windows Printer via SAMBA, Browse (I can find the printer no problems here), Foward, Choose Driver Dialog, Brother, My printer is not in this list So the next thing I tried was to download the printer driver from here http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/download_prn.html The driver installed fine but my printer still does not appear in the list. I also tried installing the cups wrapper but that gave the following error. Restarting Common Unix Printing System: cupsd [ OK ] cp: cannot stat `/usr/share/cups/model/MFC7420.ppd': No such file or directory dpkg: error processing cupswrappermfc7420 (--install): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: cupswrappermfc7420 I tried connecting the printer directly but even though I have installed the driver, when I go to printers and click on the printer (it shows up fine as a USB printer) then it say searching for drivers and then gives me a list, this is the same list as before which doesn't have my printer. It really shouldn't be this hard. on window you don't have to installing anything it just works and the same is true for my brothers Mac. How do I print to my printer?

  - by TestSubject528491

  In the head of my HTML page, I have: <script src="https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js"></script> When I load the page in my browser (Google Chrome v 27.0.1453.116) and enable the developer tools, it says: Refused to execute script from 'https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled. Indeed, the script won't run. Why does Chrome think this is a plain text file? It clearly has a .js file extension. Since I'm using HTML5, I omitted the type attribute, so I thought that might be causing the problem. So I added type="text/javascript" to the <script> tag, and got the same result. I even tried type="application/javascript" and still got the same error. Then I tried changing it to type="text/plain" just out of curiosity. The browser did not return an error, but of course the JavaScript did not run either. Finally I thought the periods in the filename might be throwing the browser off. So in my HTML code, I changed all the periods to the URL escape character %2E: <script src="https://raw.github.com/cloudhead/less%2Ejs/master/dist/less-1%2E3%2E3.js"></script> This still did not work. The only thing that truly works (i.e. the browser does not give an error and the JS successfully runs) is if I download the file, upload it to a local directory, and then change the src value to the local file. I'd rather not do this since I'm trying to save space on my own website. How do I get Chrome to recognize that the linked file is actually a JavaScript type?

• Wubi installation broken by update - now unable to mount

  - by Outspaced

  As of today, my wubi installation of Ubuntu won't boot (goes straight to 'minimal bash-like interface) and I am unable to mount it when I boot straight to Ubuntu. If I boot straight into Ubuntu (not using Wubi, not going via Windows), I am able to mount the Windows partition and see the Wubi partition there: sudo mount -t ntfs /dev/sda5 /media/winxp And from there I can see the wubi root disk: /media/winxp/ubuntu/disks/root.disk But if I try to mount this: sudo mount -o loop /media/winxp/ubuntu/disks/root.disk /media/wubi I get an error: /media/winxp/ubuntu/disks/root.disk Input/Output Error If I then try fsck: sudo fsck /media/winxp/ubuntu/disks/root.disk I get this: Input/Output Error while trying to open /media/winxp/ubuntu/disks/root.disk The Superblock could not be read or does not describe a correct etx2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt and you might want to try running e2fsk with an alternate superblock: e2fsck -b 8193 <device ... this gives me the same result. There is data on this partition that I really need to be able to access, so I can't delete and reinstall. Any help much appreciated. Thanks.

  I'm having a serious problem with allegro.

• Cannot install ia32-lib package

  - by A British Person

  I have several programs that reuquire 32 bit packages (pointing to the ia32-lib package). However, when I try to install it, this happens. spirit@ubuntu:~$ sudo apt-get install ia32-libs Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: ia32-libs : Depends: ia32-libs-multiarch but it is not installable E: Unable to correct problems, you have held broken packages. No big whoop, packages die all the time. I tried a month later however and I still got this error, trying to install the specific package produces this error. spirit@ubuntu:~$ sudo apt-get install ia32-libs-multiarch Reading package lists... Done Building dependency tree Reading state information... Done Package ia32-libs-multiarch is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'ia32-libs-multiarch' has no installation candidate I am no Linux whizz-kid, but this seems to be that the package doesn't exist. I searched for Skype in the software centre (I was told this installs the 32-bit packages) and it does not appear in the software centre, and the downloadable from their website produces an error about - funnily enough - no 32-bit packages. Anyone who helps me will get a medal from the gods with the weight of a thousand planets. Just don't wear it for god's sake.

• How do I remove a malformed line from my sources.list?

  - by eminencejae

  I have unistalled and reinstalled the Ubuntu Software Center as per info I found in a similar thread and I got the same response about line 91 or something like that. I just tried to upload a screen shot but since I'm new it won't allow me to. I also can not figure out how to cut and paste anything so I have to hand type what the error screen says, both when I attempt to open the software center and nothing happens, when I try to enter commands into the terminal to uninstall, reinstall, whatever I get the same following: COULD NOT INTITIALIZE THE PACKAGE INFORMATION An unresolvable problem occured while initializing the package information Please report t:his bug against the 'update-manager' package and include the following error message: 'E: Malformed line 91 in source list/etc/apt/sources.list (dist parse) E: The list of sources could not be read., E: The package list of status file could not be parsed or opened. How do I report bugs? What can be done about this. I have searched and everything everyone says to do leads me back to the same line error message. So, I don't know how to get to line 91 in the source list; to tell you what it says. Sorry, I'm really new to this. That is what I need is to find out how to get there and fix what it says. I would really like to NOT have to re partition my hard drive and start from scratch, so I'm really looking forward to getting this problem solved. I need to be able to install new software.

• Problems when rendering code on Nvidia GPU

  - by 2am

  I am following OpenGL GLSL cookbook 4.0, I have rendered a tesselated quad, as you see in the screenshot below, and i am moving Y coordinate of every vertex using a time based sin function as given in the code in the book. This program, as you see on the text in the image, runs perfectly on built in Intel HD graphics of my processor, but i have Nvidia GT 555m graphics in my laptop, (which by the way has switchable graphics) when I run the program on the graphic card, the OpenGL shader compilation fails. It fails on following instruction.. pos.y = sin.waveAmp * sin(u); giving error Error C1105 : Cannot call a non-function I know this error is coming on the sin(u) function which you see in the instruction. I am not able to understand why? When i removed sin(u) from the code, the program ran fine on Nvidia card. Its running with sin(u) fine on Intel HD 3000 graphics. Also, if you notice the program is almost unusable with intel HD 3000 graphics, I am getting only 9FPS, which is not enough. Its too much load for intel HD 3000. So, sin(X) function is not defined in the OpenGL specification given by Nvidia drivers or something else??

• Incompleted ubuntu 12.04 install dual-boot xp

  - by Mike

  This weekend has been the 1st time i've tried to install ubuntu. On the initial install, (I am using a USB) the installation went all the way through and asked to restart when completed. I was not able to get grub to boot and kept going through windows. After some research I found some articles on updating/reinstalling grub, so I followed those. I finally got grub to load after a day but there was no windows option only the Ubuntu 12.04 which when I selected it only gave me a fatal error 17. I booted from the usb again and deleted the partitions and installed again. This time I got an error 15. I then booted through xp and downloaded the WUBI.exe and uninstalled ubuntu and reinstalled again. The installation went to the very end and then gave an error message (which I don't remember exactly what it said) something along the lines of checking my logs on my C drive. I then uninstalled ubuntu and removed the wubi.exe file and wiped my usb and did the download to the usb again. Booted through usb and ran the install process again. It again went through the install process but after creating username and password and hitting continue the installation dialogue box disappears and the mouse spinning wheel is displayed but I do not receive the prompt to restart. I can still access the side menu for ubuntu but the wheel keeps spinning. How to I get Ubuntu to install properly

• unable remove/reinstall libxss1:amd

  - by mono

  Whenever I try to install anything (software-center or apt-get) I get an error report stating that libxss1:amd is in a "very bad inconsistent state" (translated from german) and that I should reinstall it. That would not bother me much but I am never sure if the stuff I'm trying will be working in the end. It really resists from being repaired apt-get install, apt-get remove, apt-get -f install, and all the usual suspects - nothing works. It always comes to: dpkg: Fehler beim Bearbeiten von libxss1:amd64 (--configure): Paket ist in einem sehr schlechten inkonsistenten Zustand - Sie sollten es nochmal installieren, bevor Sie die Konfiguration versuchen. Fehler traten auf beim Bearbeiten von: libxss1:amd64 E: Sub-process /usr/bin/dpkg returned an error code (1) I posted the error as is, since my translation might not be exact. But I guess you can figure from my text. I found out that this file is the X screen saver. Maybe I should kill it before handling that file. If thats so, than please tell me how. Thanks for your help, thomas
