  • How do I automatically start Clamz with AMZ files for Amazon MP3 downloads?

    - by Takkat
    Chromium can open downloaded files with the default application (e.g. PDF in Evince). In my setup a downloaded .AMZ (for Amazon MP3) always opened with Gedit. However I would like to have all downloaded .amz files to autromatically open with Clamz, a command line tool for downloading that works like a charm. As in Nautilus my .amz files were associated to open with Gedit too I thought it was a good idea to add a clamz.desktop file in ~/.local/share/applications (according to this answer) [Desktop Entry] Encoding=UTF-8 Name=Clamz Comment=Open AMZ files for Amazon MP3 download Exec=/usr/bin/clamz %u Terminal=True Type=Application Icon= Categories=Application; StartupNotify=true MimeType=audio/x-amzxml; NoDisplay=true This lets me choose Clamz as default application in Nautilus. But when opening an .amz file in Nautilus it still does not open with Clamz as expected but is treated as an executable text file instead (note that the executable bit is not set!). Is there any other way to make Chromium or Nautilus always open an .amz file with Clamz? Did I miss to change setting in another place?

  • Proper way to do texture mapping in modern OpenGL?

    - by RubyKing
    I'm trying to do texture mapping using OpenGL 3.3 and GLSL 150. The problem is the texture shows but has this weird flicker I can show a video here. My texcords are in a vertex array. I have my fragment color set to the texture values and texel values. I have my vertex shader sending the texture cords to texture cordinates to be used in the fragment shader. I have my ins and outs setup and I still don't know what I'm missing that could be causing that flicker. Here is my code: Fragment shader #version 150 uniform sampler2D texture; in vec2 texture_coord; varying vec3 texture_coordinate; void main(void) { gl_FragColor = texture(texture, texture_coord); } Vertex shader #version 150 in vec4 position; out vec2 texture_coordinate; out vec2 texture_coord; uniform vec3 translations; void main() { texture_coord = (texture_coordinate); gl_Position = vec4(position.xyz + translations.xyz, 1.0); } Last bit Here is my vertex array with texture coordinates: GLfloat vVerts[] = { 0.5f, 0.5f, 0.0f, 0.0f, 1.0f, 0.0f, 0.5f, 0.0f, 1.0f, 1.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.5f, 0.0f, 0.0f, 1.0f, 0.0f}; //tex x and y If you need to see all the code, here is a link to every file. Thank you for your help.

  • Looking for a free SMTP server program

    - by Richard
    Hello all, I am looking for a free SMTP server. I am currently using Free SMTP Server http://www.softstack.com/freesmtp.html This software works great other than the fact that it can only send 10 messages a day. This is a bit of a problem seeing that the software I am writing needs to send a message every half hour. Anyone knows of a good piece of software that does the same thing, but does not limit the amount of messages that can be sent in a day? I am using Windows XP, so software must be Windows friendly

  • two thoughts about career excellence

    - by john.rose
    I love Dickens, warts and all. Sometimes he is sententious, and (like the mediocre modern I am) at such points I am willing to listen non-ironically. This bit here struck me hard enough to stop and write it down: I mean a man whose hopes and aims may sometimes lie (as most men's sometimes do, I dare say) above the ordinary level, but to whom the ordinary level will be high enough after all if it should prove to be a way of usefulness and good service leading to no other. All generous spirits are ambitious, I suppose, but the ambition that calmly trusts itself to such a road, instead of spasmodically trying to fly over it, is of the kind I care for. It is Woodcourt's kind. (John Jarndyce to Esther Summerson, Bleak House, ch. 60) Woodcourt is, of course, one of the heroes of the story. It is a heroism that is attractive to me. Here is a similar idea, from the Screwtape Letters. In the satirically inverted logic of that book, the “Enemy” is God, the enemy of the devils but the author of good: The Enemy wants to bring the man to a state of mind in which he could design the best cathedral in the world, and know it to be the best, and rejoice in the, fact, without being any more (or less) or otherwise glad at having done it than he would be if it had been done by another. (C.S. Lewis, Screwtape Letters, ch. 14) Though I will be happy with a good Bazaar, I also dream of Cathedrals. Put whatever name you like on it, as long as I get some part in the fun of building a good one.

  • CLR Profiler Allocated Bytes and XNA ContentManager

    - by Vackup
    I've been fighting with XNA ContentManager and memory allocations for some weeks because I'm trying to port my game from XNA (Windows) to ExEn / Monotouch (iphone). The problem is that after playing a few levels, my game exits unexpectedly on a real iPhone device (not simulator). Profiling memory usage on Windows with CLRProfile, I found some useful stuff but I also found something I dont understand. If I use 2 ContentManagers (1 for shared assets and 1 for level assets), when profiling, "Allocated Bytes" grows and grows after level through level but Memory consumption measured by Windows Task Manager stays constant (down when I unload the content manager and up again when I load content). Obviously, I contentManager.Unload() when level ends. After a few levels my game exits unexpectedly on an iPhone device. If I use 1 content manager, "CRLProfiler Allocated Bytes" stays constant on Windows and on the iPhone; I can play the game normally and it doesnt exit unexpectedly. I use the same assets level through level. It seems like in ios (iPhone) when loading and unloading the same assets, it allocates memory and consumes all device memory, so the ios kill it. Can anybody explain me how this really works? I've read quite a bit, but I still don't understand what's going on.

  • moving my site, IP change worries...

    - by Sherif Buzz
    Hi all, my site has outgrown the shared hosting account it's on and i've setup a VPS that i'll be moving to soon. I cannot keep the same IP between my new account and the old one and I'm a bit at loss as to how to minimize user downtime while the new IP is reflected in all DNS caches. Note I cannot have the site running on both accounts at the same time as it's a dating site and this would cause data inconsistency. Here's what i am planning to do : Put up a 'under maintenance' page on old host Get the site up and running on new host, and update domain to point to new host. Hope downtime isn't too long. Would it be a good idea to have a link on the page in (1) that opens the new site but using it's ip ? Or even redirect all requests at the old host, to the new one (again by ip) ? Any advice much appreciated.

  • List of Asus U46 laptop troubles with Ubuntu 12.04

    - by Cybertib
    I've bought my ASUS U46 last february. I would like to make it work better with Ubuntu 12.04. Note taht I was forced to install Ubuntu 12.04 (before its publication) by ethernet. After a successfull install, several problem remain unfixed such as : USB 3 just does not work correctly. Can be fixed, but I didn't succeed yet. Nvidia Optimus (means that you can use Intel Chipset or the Nvidia GeForce) is possible to use thanks to BumbleBee project. It seems to work, though. But Nvidia tools still say they don't see any Nvidia driver installed. Battery duration can be optimised by using Laptop-tools. Any standby state lead to a X server crash. A good CTRL+ALT+F1 login and "shutdown -r" avoids a brutal power off. And since few weeks, I have some bug reports right after boot about "unattended-upgrade", and dpkg troubles after any apt-get install or update (Linux kernel doesn't compile anymore), ... Are there any ways to fix those troubles ? I would need a bit of assistance, in fact. Thank you for you help, Sincerly yours, Thibault

    I have not been able to get this to work. We are running our OEM grid control database/oms on Red Hat 5(32 bit), but our databases are on Solaris x86-64. I could not mass deploy agents since the Operating Systems were different. When I download patches it is by OS. Is there a way to mass deploy to multiple operating systems? I have alot of databases. I was given the redhat server for OEM because it was available. We are have 10.1,10.2, and 11.1 databases. OEM DB is 10.2.0.5

  • Hyper V cluster - one VM won't migrate

    - by Chris W
    We have a Failover Cluster built up on 6 blades, each running Hyper V. Each box is running Server 2008 R2. We've got a number of VMs running that all have the same basic config: VHD stored on a cluster shared volume. 2 virtual NICs (1 for LAN connection and 1 for SAN connection). All of our VMs will happily migrate between any other blade apart from one single VM which is running fine on it's current blade but will not migrate to any other location. What could be the cause of it or where should I look to get a detailed error message as I can't seem to find much information logged in any of the logs. Edit: I know the usual culprit is mis-matching resource names. We've already been there with the NICs named differently on some of the blades. As far as we can tell now everything looks to be identical on each bit of metal.

  • Windows 7 on 1st Gen MacbookPro Unibody (Q4-2008) - power problems.

    - by typemismatch
    I have the first generation macbook pro, purchased Q4 2008. I've been trying to run Windows 7 and can get it all installed great with the BootCamp 3.1 64 bit drivers however ... power management isn't great. The screen and keyboard don't automatically dim - the laptop gets too hot. I noticed on some newer macbook pros that windows 7 works perfectly and the above doesn't happen. Does anyone know if there really is a hardware issue with this 1st gen or is there some firmware update I can use to fix this? Thanks!

  • Looking for 'WinHlp32.exe compatible' replacement for free redistribution under vista and windows 7

    - by richardboon
    Our software installs a package of legacy software for the client, some of it has old hlp file from 3rd party vendor requiring winhlp32.exe (note: we have no legal right to modify the hlp). Those client may only have cd/dvd and might not have internet access, etc. So I need a free 'WinHlp32.exe compatible' replacement for our redistribution under vista and windows 7. Background of problem: -Microsoft stopped including the 32-bit Help file viewer in Windows releases beginning with Windows Vista and Windows Server 2008. -Starting with the release of Windows Vista and Windows Server 2008, third-party software developers are no longer authorized to redistribute WinHlp32.exe with their programs. http://support.microsoft.com/kb/917607

  • Rethinking Oracle Optimizer Statistics for P6 Part 2

    - by Brian Diehl
    In the previous post (Part 1), I tried to draw some key insights about the relationship between P6 and Oracle Optimizer Statistics.  The first is that average cardinality has the greatest impact on query optimization and that the particular queries generated by P6 are more likely to use this average during calculations. The second is that these are statistics that are unlikely to change greatly over the life of the application. Ultimately, our goal is to get the best query optimization possible.  Or is it? Stability No application administrator wants to get the call at 9am that their application users cannot get there work done because everything is running slow. This is a possibility with a regularly scheduled nightly collection of statistics. It may not just be slow performance, but a complete loss of service because one or more queries are optimized poorly. Ideally, this should not be the case. The database optimizer should make better decisions with more up-to-date data. Better statistics may give incremental performance benefit. However, this benefit must be balanced against the potential cost of system down time.  It is stability that we ultimately desire and not absolute optimal performance. We do want the benefit from more accurate statistics and better query plans, but not at the risk of an unusable system. As a result, I've developed the following methodology around managing database statistics for the P6 database.  1. No Automatic Re-Gathering - The daily, weekly, or other interval of statistic gathering is unlikely to be beneficial. Quite the opposite. It is more likely to cause problems. 2. Smart Re-Gathering - The time to collect statistics is when things have changed significantly. For a new installation of P6, this is happening more often because the data is growing from a few rows to thousands and more. But for a mature system, the data is not changing significantly from week-to-week. There are times to collect statistics: New releases of the application Changes in the underlying hardware or software versions (ex. new Oracle RDBMS version) When additional user groups are added. The new groups may use the software in significantly different ways. After significant changes in the data. This may be monthly, quarterly or yearly.  3. Always Test - If you take away one thing from this post, it would be to always have a plan to test after changing statistics. In reality, statistics can be collected as often as you desire provided there are tests in place to verify that performance is the same or better. These might be automated tests or simply a manual script of application functions. 4. Have a Way Out - Never change the statistics without a way to return to the previous set. Think of the statistics as one part of the overall application code that also includes the source code--both application and RDBMS. It would be foolish to change to the new code without a way to get back to the previous version. In the final post, I will talk about the actual script I created for P6 PMDB and possible future direction for managing query performance.

  • Audio not working in 12.10

    - by frampy
    I did a clean install of 12.10, when I open Sound Settings in gnome the only device in the list is "Dummy Output", and sound is not working. Sound worked fine out of the box in 12.04 I ran alsamixer, it says my card is "HDA Intel", and chip is "Realtek ALC880". The alsamixer playback output was set to mute at first, unmuting did not fix. I checked out the info at http://www.unixmen.com/2012003-howto-resolve-nosound-problem-on-ubuntu/ as suggested on a similar question, I've done everything there except installing the ubuntu audio dev team driver. Should I try install this? Edit: I've been reading the sound troubleshooting guide at https://help.ubuntu.com/community/SoundTroubleshooting It looks like Ubuntu is finding my audio device correctly. mike@wucade:~$ lspci -v | grep -A7 -i "audio" 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03) Subsystem: Albatron Corp.

  • How can you easily determine the textureRect for tiled maps in SFML 2.0?

    - by ThePlan
    I'm working on creating a 2d map prototype, and I've come across the rendering bit of it. I have a tilesheet with tiles, each tile is 30x30 pixels, and there's a 1px border to delimitate them. In SFML the usual method of drawing a part of a tilesheet is declaring an IntRect with the rectangle coordinates then calling the setTextureRectangle() method to a sprite. In a small game it would work, but I have well over 45 tiles and adding more every day, I can't declare 45 intRects for every material, the map is not optimized yet, it would get even worse if I would have to call the setTextureRect() method, aside from declaring 45 rectangleInts. How could I simplify this task? All I need is a very simple and flexible solution for extracting a region of the tilesheet. Basically I have a Tile class. I create multiple instances of tiles (vectors) and each tile has a position and a material. I parse a map file and as I parse it I set the materials of the map according to the parsed map file, and all I need to do is render. Basically I need to do something like this: switch(tile.getMaterial()) { case GRASS: material_sprite.setTextureRect(something); window.draw(material_sprite); break; case WATER: material_sprite.setTextureRect(something); window.draw(material_sprite); break; // handle more cases }

  • what is the purpose of the files in this directory: /var/lib/apt/lists?

    - by Magpie
    linux lubuntu HD4000 intel ivy-bridge 8gb 1600 ram. I am getting a duplicate entry error message from synaptic package manager and it says the problem is there. I am wondering a few things: What this directory is. Whether it safe to simply delete the offending duplicates from there. Whether this is a useful new discovery... Is this where all the packages I have no use for end up and something I can edit to suit my fancy in the long run? It would be nice to be able to reduce the clutter in my package manager. Especially find a way to get rid of all the 32 bit stuff or older versions of programs I have downloaded manually elsewhere. I had meant to post this in linux! So if this is wrong place let me know and I will move it there!

  • Strange Phantom Local Disks appearing in my drive list...

    - by Paul
    Win7 Home Prem 32 bit I seem to have several phantom Local Disks mapped to different letters, they are of 0 bytes in size? Strangely they do not show up when i view my drives through windows explorer but if i open an application such as ACDSee Pro or MS Word and then go to open a file i can see all these Local Disks mapped to different letters. This means when i plug in my external hard disk it ends up mapped to letter R instead of its usual G which messes up any programs i have pointing to it by default. How did they get there and more importantly how do i get rid of them please??

  • MVVM and service pattern

    - by alfa-alfa
    I'm building a WPF application using the MVVM pattern. Right now, my viewmodels calls the service layer to retrieve models (how is not relevant to the viewmodel) and convert them to viewmodels. I'm using constructor injection to pass the service required to the viewmodel. It's easily testable and works well for viewmodels with few dependencies, but as soon as I try to create viewModels for complex models, I have a constructor with a LOT of services injected in it (one to retrieve each dependencies and a list of all available values to bind to an itemsSource for example). I'm wondering how to handle multiple services like that and still have a viewmodel that I can unit test easily. I'm thinking of a few solutions: Creating a services singleton (IServices) containing all the available services as interfaces. Example: Services.Current.XXXService.Retrieve(), Services.Current.YYYService.Retrieve(). That way, I don't have a huge constructor with a ton of services parameters in them. Creating a facade for the services used by the viewModel and passing this object in the ctor of my viewmodel. But then, I'll have to create a facade for each of my complexe viewmodels, and it might be a bit much... What do you think is the "right" way to implement this kind of architecture ?

  • Is there a PROPRIETARY driver (NVIDIA or ATI) that actually works with 12.10?

    - by DS13
    NOTE: I see many similar topics on this, but I've tried all their suggestions, and nothing has worked. THE MAIN DIFFERENCE SEEMS TO BE: I always get a black screen with a blinking cursor, while others seem to get through the boot-up and see distorted graphics or just their wallpaper. ISSUE: I do a clean install of Ubuntu 12.10. Boots fine with the “nouveau” graphics driver – graphics (even just menus) are very slow, choppy, and distorted. The three other driver options in Ubuntu (official NVIDIA drivers), all result in a variation of the black screen on boot up. There will be NO access to a command line/GUI in anyway what-so-ever (tried every option recommended out there, but the system is unusable at this stage). I can only reinstall, and try different drivers…and I only ever get one shot at it. QUESTIONS: -Does anyone know of a PROPRIETARY driver that will actually work on 12.10 with a NVIDIA or ATI card? -Should I just buy a newer graphics card to put in as a replacement? MORE INFO: This is my second computer, and I’m just trying to get a working install of Ubuntu on it. I don’t want to put much money into it, as I have seen Ubuntu run great on much older/less capable machines. I’ve got a decent'ish Core2Duo Intel processor (2.13Ghz), 2GB of RAM, 320GB hard drive, 32-bit architecture, and there is no other O/S installed. It appears as if the graphics card (NVIDIA Geforce 7350 LE) is holding me back. TRIED SO FAR: -all drivers available in Ubuntu *all fail -manual install of some different NVIDIA drivers *all fail -also tried installing the generic kernel, Nvidia driver doesn't work in 12.10 *no difference -tried installing 12.04 *same results -every method suggested to at least get a command line after switching to a NVIDIA driver *all fail -UPDATE- Re-tried everything above with a new NVIDIA Geforce 210...same results for everything. -UPDATE #2- Re-tried everything above with a new AMD Radeon HD 6450...installed the proprietary driver from Ubuntu's "Software Sources" menu...EVERYTHING NOW WORKS. See "answer" below for summary.

    I have a load of media files on my PC, mostly AVI/MKV and some mpegs. On windows, I would use ConvertXToDVD to convert these to DVD format, and to burn to disc. That application also lets you save a bit of space on the DVD to put the original file in its AVI format on as well. How can I do this on linux? What are the alternatives to this Windows application? I could try to run ConvertXtoDVD under wine but I would prefer to find a native linux solution Thanks in advance!

  • Workaround broken sudo?

    - by perreal
    I managed to break sudo by deleting the libc.so.6 sym-link in /lib. I copied the actual file and created a symbolic link with the same name under my home directory by using LD_PRELOAD=/lib/libc-2.11.3.so. At this point, all binaries linking libc are working through preload except sudo. For sudo, I need to write (and don't know why): $ /lib/ld-linux-x86-64.so.2 --library-path . /usr/bin/sudo but this gives me: $ sudo: must be setuid root Checking the permissions: $ ls -l /usr/bin/sudo $ -rwsr-xr-x 2 root root 166120 So the setuid bit is actually set. Question: I need to create a symbolic link named /lib/libc.so.6 through my active ssh connection without using sudo, or, make sudo work somehow. I don't have the root password and I can't connect through ssh anymore. Is there any other way I can get authorization?

Thanks to Priti Pushpak (my wife) for all the amazing Windows Phone 7 apps she is creating and uploading on appHub… I kind of like refreshing feel of win8 and apps. I also have fair bit of exposure on iPhone / iPad; Mac apps and I do put my two cents for win8 as well. If not an instant hit; win8 apps surely grows on you. So eventually win8 platform is here to stay. (oh yes and I cannot tell you how much hope I have for WP8 platform as well). Nevertheless; here is few topics I covered in a session on .Net 4.5  and on popular demand I am posting it all here… Note that for the demo you must have Win8 installed along with VS2012. The Demo includes a ASP .NET Web API http://www.slideshare.net/spushpak/new-features-in-net-45-c-and-vs2012 New features in .NET 4.5, C# and VS2012 from Subodh Pushpak The slide deck, demo and the session recording is at: http://sdrv.ms/R1thCf and https://www.dropbox.com/sh/0ogfayv0djfafyg/hfw5mNLaz9

  • RHEL 6.5 and LDAP

    - by zuboje
    I am trying to connect our Active directory server to brand new RHEL 6.5 server. I want to authenticate users using AD credentials, but I want to restrict that only certain users can login, I don't want to allow anybody from AD to connect to it. I would like to use something like this: CN=linuxtest,OU=SecurityGroups,DC=mydomain,DC=local but I am not sure how would I setup OU and CN. I use sssd for authentication and my id_provider = ad. I wanted to use id_provider = ldap, but that did not work at all and RHEL customer service told me to setup this way. But I want to have a little bit more control who can do what. I know I can use this to restrict simple_allow_users = user1, user2, but I have 400+ users, I really don't want to go and type them all. Question is how would I setup OU or CN for my search?

  • Tile sizes in 2D games

    - by Ephismen
    While developing a small game using tile-mapping method a question came to my mind: I would develop the game on Windows but wouldn't exclude adapting it to another platform. What size(in pixels) would you recommend using for creating the tiles of a tile-mapped game(ie: RPG) with the following requirements? Have an acceptable level of detail without having too many tiles. Having a decent map size. Allow adaptation of the game on a handheld(ie: PSP), smartphone or a computer without too much loss of detail or slowdowns. Allow more or less important zoom-in / zoom-out. Have a resolution of tile that permits either pixel-perfect collision or block-collision. Anything from a good explanation to a game example is useful as long as it can fit the requirements. This question may seem a bit simplistic, but I noticed that many Indies game developer were using inappropriate scales scenery. Also sorry for the poor syntax and the lack of vocabulary of my question, being a non-native English speaker doesn't help when talking about computers programming.
