• How to make VLC play a .vlm configuration file in "With no interface mode"?

  - by Ole Jak

  How to make VLC play a VLM configuration file (.vlm) in "With no interface mode" on Windows? So I have a VLM configuration file that should stream audio from mic to localhost so no VLC user interface is needed. If I say to Windows "play VLM file with VLC" it plays correctly, starts the server where I need and streams data. But how to do such a thing manually from the command line (so we suppose we can call vlc.exe by VLC and we are now in folder with the vlc.exe and vlcConfig.vlm files)?

• "Programming error" exceptions - Is my approach sound?

  - by Medo42

  I am currently trying to improve my use of exceptions, and found the important distinction between exceptions that signify programming errors (e.g. someone passed null as argument, or called a method on an object after it was disposed) and those that signify a failure in the operation that is not the caller's fault (e.g. an I/O exception). As far as I understand, it makes little sense for an immediate caller to actually handle programming error exceptions, he should instead assure that the preconditions are met. Only "outer" exception handlers at task boundaries should catch them, so they can keep the system running if a task fails. In order to ensure that client code can cleanly catch "failure" exceptions without catching error exceptions by mistake, I create my own exception classes for all failure exceptions now, and document them in the methods that throw them. I would make them checked exceptions in Java. Now I have a few questions: Before, I tried to document all exceptions that a method could throw, but that sometimes creates an unwiedly list that needs to be documented in every method up the call chain until you can show that the error won't happen. Instead, I document the preconditions in the summary / parameter descriptions and don't even mention what happens if they are not met. The idea is that people should not try to catch these exceptions explicitly anyway, so there is no need to document their types. Would you agree that this is enough? Going further, do you think all preconditions even need to be documented for every method? For example, calling methods in IDisposable objects after calling Dispose is an error, but since IDisposable is such a widely used interface, can I just assume a programmer will know this? A similar case is with reference type parameters where passing null makes no conceivable sense: Should I document "non-null" anyway? IMO, documentation should only cover things that are not obvious, but I am not sure where "obvious" ends.

• Make own dial-up ISP using broadband connection [on hold]

  - by SkylarMT

  So, I see no reason why this wouldn't be possible. I have a Linux server (a Raspberry Pi to be exact) connected via Ethernet to a broadband ISP. I want to be able to dial a number, have it go through the normal telephone network, onto the Internet via a VoIP provider (I know you can call a Skype user from a landline), to my Raspberry Pi, and then have the Pi connect me to the Internet. I've found guides on making your own ISP, but they all involve a dedicated phone line on the server end. Is there a way to do this with no modem on the server end? I live in an area with a lot of people still on dialup, and if I pull this off I could make some extra money. Thanks!

• Xmonad Xsession

  - by AntLord

  My user level: noob-ish, so please bear with me I'm running 12.04 LTS. I have installed and, to some extent, configured xmonad 0.10 The "automagically" created xsession for it works fine as it is, but when I login it won't run a startup script I've created and "call from" /usr/share/xsessions/xmonad.desktop, if that's right. I've read pretty much all I could find about .xinitrc and .xsession, I tried that and it somehow messed up the other "sessions", if I'm explaining myself correctly. Had to $unity --reset to have the "main session" working again. Anyway, my question is, how do I autostart xmobar and set a desktop background after login into xmonad's default Xsession? I tried this script, start-xmonad: #!/bin/bash # #I only used one of the following each time I tried, none worked #Also, do I really need the '&'? I know what they're for, but... nitrogen --restore & feh --bg-scale ~/Pictures/picture.png & #Then I want xmobar to start, again do I need the '&'? I know it's for it to run #in the background, but I tried removing the '&' and xmonad still launched xmobar & #Finally, the only thing that seems to work in this script exec xmonad Yes, I made sure I did chomd +x ~/start-xmonad The xmonad.desktop is [Desktop Entry] Name=XMonad Encoding=UTF-8 Comment=Lightweight tiling window manager Exec=/home/myusername/start-xmonad Icon=custom_xmonad_badge.png Type=XSession So, this didn't work, now I'm here. Please help :s thanks

• Should a sysadmin contractor charge overtime for off-peak hours?

  - by Jakobud

  This is not necessarily a server-related question, but more of a system admin question that I think would related to many on SF. I'm doing Sysadmin/IT consulting for a small company. I only work about 3 days a week for them on average. If a server goes down or something like that during off hours (nights, weekends, 3am, etc) and they need it fixed during those time periods, should I be charging overtime for that? I would I not be justified in charging overtime until I've logged 40 hours for the week? Perhaps calling it overtime isn't the best name. I guess maybe its better to call it an off-peak hourly rate. Anyways I just was curious what other consultants did in these circumstances.

• New features for Expression Blend 4 Release Candidate

  - by kaleidoscope

  With Microsoft Expression Blend 4, you can create websites and applications based on Microsoft Silverlight 3 and Microsoft Silverlight 4, and desktop applications based on Windows Presentation Foundation (WPF) 3.5 with Service Pack 1 (SP1) and WPF4. Expression Blend provides new support for prototyping, interactivity through behaviors, special Silverlight functionality, and on-the-fly sample data generation. Expression Blend includes new behaviors that are quickly and easily configured Expression Blend offers new sample data, behaviors, and features of project templates to support the Model-View-ViewModel (MVVM) pattern The MVVM pattern is a way to structure a Silverlight or WPF application so that user interface (UI) objects are as decoupled as possible from the application's data and behavior. This makes it easier for design tasks and development tasks to be performed independently and without breaking each other. Essentially, your UI is the View. You bind objects in the View to properties and commands of the ViewModel, and the View can also call methods on the ViewModel. Compatible with Silverlight 3 and WPF 3.5 with Service Pack 1 (SP1) Interoperate able with Visual Studio. Included New Shapes: The Assets panel in Expression Blend contains a new Shapes category, including presets for the easy creation of arcs, arrows, callouts, and polygons. New Controls: Expression Blend has tooling support for the RichTextBox control in Silverlight. XAML cleanliness :Expression Blend generates less XAML with respect to animations and animation-related properties. MVVM project template: Expression Blend includes a new project template that offers a basic starting point for Model-View-ViewModel pattern applications. Run project with CTRL+F5:To improve consistency with Visual Studio, you can now invoke the Run Project command by pressing either CTRL+F5 or F5 Technorati Tags: Rituraj,Features of Expression Blend4 RC

• Relationship between Repository and Unit of Work

  - by NullOrEmpty

  I am going to implement a repository, and I would like to use the UOW pattern since the consumer of the repository could do several operations, and I want to commit them at once. After read several articles about the matter, I still don't get how to relate this two elements, depending on the article it is being done in a way u other. Sometimes the UOW is something internal to the repository: public class Repository { UnitOfWork _uow; public Repository() { _uow = IoC.Get<UnitOfWork>(); } public void Save(Entity e) { _uow.Track(e); } public void SubmittChanges() { SaveInStorage(_uow.GetChanges()); } } And sometimes it is external: public class Repository { public void Save(Entity e, UnitOfWork uow) { uow.Track(e); } public void SubmittChanges(UnitOfWork uow) { SaveInStorage(uow.GetChanges()); } } Other times, is the UOW whom references the Repository public class UnitOfWork { Repository _repository; public UnitOfWork(Repository repository) { _repository = repository; } public void Save(Entity e) { this.Track(e); } public void SubmittChanges() { _repository.Save(this.GetChanges()); } } How are these two elements related? UOW tracks the elements that needs be changed, and repository contains the logic to persist those changes, but... who call who? Does the last make more sense? Also, who manages the connection? If several operations have to be done in the repository, I think using the same connection and even transaction is more sound, so maybe put the connection object inside the UOW and this one inside the repository makes sense as well.

• How can I fix this configure error?

  - by balor123

  I'm trying to build mosh from source on a SUSE10 machine and am getting the following error: checking for protobuf... no configure: error: Package requirements (protobuf) were not met: No package 'protobuf' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables protobuf_CFLAGS and protobuf_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. I downloaded the source to protobuf and installed it in a custom path as well. I'm not using a package manager for any of this and cannot for various reasons outside the scope of the question. I added that custom path to my PATH and rehashed. Typically, this is enough for configure but in this case its not doing the trick. I added the prefix for protobuf to PKG_CONFIG_PATH but am still hitting this error. What should I do next to get past this error?

• "Half" ssh authorization to a server with git repository

  - by hsz

  Hello ! Currently I have purchased web hosting with ssh access. I have created a git repository on it and if I set my public key in ~/.ssh/authorized_keys file, I have access to that repo, I can push/pull data, etc. This solution allows access for every user that has his public key in authorized_keys file. But there is one thing that I want to avoid. Every user can login to the server too and has access to whole ssh account. Is it possible to create a blacklist of users' keys that will not have an access to ssh ? I see it that way: user logs in to a git - ok, allow for every one user logs in to ssh account ~/.profile file is hooked and called a custom script: check user's public key if public key is in ~/.ssh/blacklist_keys call bash exit/logout Is it possible in any way ?

• Redirecting to a diferent exe for download based on user agent

  - by Ra

  I own a Linux-Apache site where I host exe files for download. Now, when a user clicks this link to my site (published on another site): http://mysite.com/downloads/file.exe I need to dynamically check their user agent and redirect them to either http://mysite.com/downloads/file-1.exe or http://mysite.com/downloads/file-2.exe It seems to me that I have to options: Put a .htaccess file stating that .exe files should be considered to be scripts. Then write a script that checks the user agent and redirects to a real exe placed in another folder. Call this script file.exe. Use Apache mod-rewrite to point file.exe to redirect.php. Which of these is better? Any other considerations? Thanks.

• How-to get the binding for a tab in the Dynamic Tab Shell Template

  - by Frank Nimphius

  The Dynamic Tab Shell template does expose a method on the Tab.java class that allows you to get access to the ADF binding container for a tab. At least in theory this works, because in practice this call always returns a null value (a bug is filed for this). To work around the problem, you can use code similar to the following to get the ADF binding for a specific tab DCBindingContainer currentBinding = (DCBindingContainer) BindingContext.getCurrent().getCurrentBindingsEntry(); DCBindingContainer templateBinding = (DCBindingContainer)currentBinding.get("ptb1"); DCBindingContainer tabBinding= (DCBindingContainer)templateBinding.get("r"+0);  In the code line above, the tabBinding variable will hold the binding reference to the first tab in the dynamic tab shell template. Note that the tab doesn't need to be visible for this (which has to do with how the template works).  "ptb1" is the template reference name in the PageDef file (Executable section) of the template consumer view. Check this string in your page before using this code. If it differs, change it also in the code above. "r0" is the binding reference of the first tab in the template. Te last tab is referenced by "r14".

• Sprites rendering blurry with velocity

  - by ashes999

  After adding velocity to my game, I feel like my textures are twitching. I thought it was just my eyes, until I finally captured it in a screenshot: The one on the left is what renders in my game; the one on the right is the original sprite, pasted over. (This is a screenshot from Photoshop, zoomed in 6x.) Notice the edges are aliasing -- it looks almost like sub-pixel rendering. In fact, if I had not forced my sprites (which have position and velocity as ints) to draw using integer values, I would swear that MonoGame is drawing with floating point values. But it isn't. What could be the cause of these things appearing blurry? It doesn't happen without velocity applied. To be precise, my SpriteComponent class has a Vector2 Position field. When I call Draw, I essentially use new Vector2((int)Math.Round(this.Position.X), (int)Math.Round(this.Position.Y)) for the position. I had a bug before where even stationary objects would jitter -- that was due to me using the straight Position vector and not rounding the values to ints. If I use Floor/Ceiling instead of round, the sprite sinks/hovers (one pixel difference either way) but still draws blurry.

• Adding file type to ack permanently

  - by Martin Tóth

  I've recently learned how to let ack support more filetypes (adding the following to .ackrc): --type-add latte=.latte Unfortunately, that produces an info line on every ack search I use, even ones with 0 results. $ ack --latte dump ack: --type-add: Type "latte" does not exist, creating with ".latte" ... Is there a way to make this a more permanent addition? (i.e. get rid of this info line) This looks to me like it's adding this new type on every ack call. Is it a problem with my installation of ack? I'm on Mac OS X 10.5.8 with ack 1.92 (Running under Perl 5.10.1)

• Why isn't there a typeclass for functions?

  - by Steve314

  I already tried this on Reddit, but there's no sign of a response - maybe it's the wrong place, maybe I'm too impatient. Anyway... In a learning problem I've been messing around with, I realised I needed a typeclass for functions with operations for applying, composing etc. Reasons... It can be convenient to treat a representation of a function as if it were the function itself, so that applying the function implicitly uses an interpreter, and composing functions derives a new description. Once you have a typeclass for functions, you can have derived typeclasses for special kinds of functions - in my case, I want invertible functions. For example, functions that apply integer offsets could be represented by an ADT containing an integer. Applying those functions just means adding the integer. Composition is implemented by adding the wrapped integers. The inverse function has the integer negated. The identity function wraps zero. The constant function cannot be provided because there's no suitable representation for it. Of course it doesn't need to spell things as if it the values were genuine Haskell functions, but once I had the idea, I thought a library like that must already exist and maybe even using the standard spellings. But I can't find such a typeclass in the Haskell library. I found the Data.Function module, but there's no typeclass - just some common functions that are also available from the Prelude. So - why isn't there a typeclass for functions? Is it "just because there isn't" or "because it's not so useful as you think"? Or maybe there's a fundamental problem with the idea? The biggest possible problem I've thought of so far is that function application on actual functions would probably have to be special-cased by the compiler to avoid a looping problem - in order to apply this function I need to apply the function application function, and to do that I need to call the function application function, and to do that...

  13 days ago I wrote a blog post entitled Introducing sp_ssiscatalog (v1.0.0.0) in which I first made mention of sp_ssiscatalog, an open source stored procedure intended to make it easy to query the SSIS Catalog. I have been working on some enhancements since then and hence v1.0.1.0 is now available for download from Codeplex. What’s new in this release This release includes the following enhancements: [execution_id] now gets returned in a call to EXEC [dbo].[sp_ssiscatalog] @operation_type='exec'; Filter events by specifying packages to ignore EXEC [dbo].[sp_ssiscatalog] @operation_type='exec',@exec_events_packagesexcluded='SomePackage.dtsx,AnotherPackage.dtsx'; [event_message_id] is now returned in a list of events List of executions can now be filtered via a minimum and maximum execution_id EXEC [dbo].[sp_ssiscatalog] @operation_type='execs',@execs_minimum_execution_id=198,@execs_maximum_execution_id=201 Events resultsets now have a field, [event_message_context_xml] that contains an XML document containing all [event_message_context] info (if any exists) Installation instructions Download the zip file at DB v1.0.1.0. It contains two files, SsisReportingPack.dacpac & SSISDB.dacpac Unzip to a folder of your choosing Open a command prompt and change to the directory into which you unzipped the files Execute: "%PROGRAMFILES(x86)%\Microsoft SQL Server\110\DAC\bin\sqlpackage.exe" /a:Publish /tdn:SsisReportingPack /sf:SSISReportingPack.dacpac /v:SSISDB=SSISDB /tsn:(local) (/tsn specifies the target server. Change as appropriate.) If everything works OK you’ll see something like the following: or depending on whether the target database already exists or not This will create a database called [SsisReportingPack] which contains [dbo].[sp_ssiscatalog] Feedback is welcomed! @Jamiet

• Why does explorer restart automatically when I kill it with Process.Kill?

  If I kill explorer.exe like this: private static void KillExplorer() { var processes = Process.GetProcessesByName("explorer"); Console.Write("Killing Explorer... "); foreach (var process in processes) { process.Kill(); process.WaitForExit(); } Console.WriteLine("Done"); } It restarts immediately. But if I use taskkill /F /IM explorer.exe, or kill it from the task manager, it doesn't restart. Why is that? What's the difference? How can I close explorer.exe from code without restarting it? Sure, I could call taskkill from my code, but I was hoping for a cleaner solution...

• How do I set up an sftp user to login with a password to an EC2 ubuntu server ?

  - by Doron

  Hello, I have an Ubuntu Server running on an EC2 instance. To login to that server I use a certificate file without any password. I've installed and configured vsftpd and created a user (let's call him "testuser") for which I've set a /bin/false ssh terminal so it will only be able to connect via sftp and upload/access files on his home directory. However - when I try to connect to the server from my computer, running sftp testuser@my-ec2-server I get Permission denied (publickey). Connection closed messages so I can't log in. How can I remove the certificate requirement for this user only (meaning, the "ubuntu" user will still have to use the certificate file to login via ssh), so normal sftp clients will be able to connect using a username and a password ? Thank you. PS Using Ubuntu Server 10.10 official AMI from canonical, 64bit on a micro instance.

• How can I fix my WRT54GL's constant crashing?

  - by Aarthi

  I have a Linksys WRT54GL wireless router (the old blue-and-black) whose underside indicates it is Version 2. I've noticed that, on wireless mode, if I am on a Skype call or in a Google Hangout, the wireless aspect will crash completely. In addition, if I am connected via an ethernet cord, my quality (that is, how my voice is received) tanks very quickly. I suspect this is due, in part, to my internet connectivity itself (I'm on Comcast instead of Verizon FiOS, as I'd prefer) but I'd like to stop my wireless router's wireless capability from crashing. I considered a firmware upgrade, but it looks to me as if I am upgraded. Short of manually running ethernet all over my house, I'm not sure what to do. How can I solve my wireless router's issues? If the answer is "buy a new router," then that's valid, as well, in my opinion.

• Perth's ADF Community Event now an open invite

  - by Chris Muir

  Yesterday saw the next ADF Community Event in Perth, and as promised we grew from 15 to 25 attendees (which is going to cause a bit of a problem soon if we keep growing as we're going to run out of powerpoints for laptops). This bimonthly enjoyed presentations from Matthew Carrigy from the Dept of Finance WA on the ADF UI Shell, a small presentation from me about how Fusion Apps uses ADF, and a hands on based on programatically extending ADF BC to call external web services.  For Matt, his first presentation to a user group, with two live demos, all kudos to him for making it look smooth (for the record I hate live demos, I always break something) - thank you Matt! We've already lined up our speakers for the next event in November, and will be inviting yet more customers to this event.  However the event will now move to an open invite, so if you'd like your staff to attend please let me know by emailing chris DOT muir AT oracle DOT com. Alternatively I've had a fair few requests now for an "Intro to ADF" 1 day session so I'll consider this soon.  Certainly if you're interested let me know as this will help organize the event earlier rather than later.
