• Watch videos from a remote computer on the LAN on ubuntu

  - by tapan

  I want to watch the videos on a friends computer on the LAN without having to download it. Both of us are running ubuntu. Now one way is to ssh to his computer, cd to the directory where the video is and run the falling command: cat video.avi | ssh me@mycomputer mplayer - This works. However the problem is that I cannot seek inside the video as in can't go forward or backward in it. Is there a method by which I can watch the videos and also seek in them ? I can install any software on his comp and my comp to aid this process. I have root level access on both computers. Any suggestions ?

• Oracle Tutor: Document Audit and Maintenance

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif";} Perhaps the most critical phase in the process of documenting policies and procedure -- and the greatest challenge to owners -- is the maintenance of published documents. Documents must reflect current practice and they must be accurate. The most effective way to ensure this is through the regular audit of documents. In the Tutor environment, a Document Owner must audit each of his/her documents once every 6 to 12 months to verify that the document reflects actual practice. If it does not, the document is updated or employees are retrained (depending on the nature of the discrepancy). If a document update is required, the Tutor system enables the owner to modify and redistribute the document within one work day. This is possible because: Documents contain a minimum of detail, thereby reducing the edits. Document format and structure are simple, so changes are easy to identify The Tutor Author software tool enables the Document Owner or the Document Administrator to update the file quickly. The Document Administrator verifies the document format and integration, publishes the document, and distributes it to all affected employees, thereby freeing the Document Owner of the more tedious tasks.

• how to setup sonicwall tz210 to port forward packets received from external ip to another external ip

  - by lplp

  i have a sonicwall tz210 on a fixed ip, say ip1. And then i have, let's say a legacy server, with external ip ip2, which sends data to ip1 (and I have another server on ip1 behind the sonicwall which receives and processes that data). I would like to set up a new server on a different external ip ip3 that will receive and process data from the legacy server. How can I setup the sonicwall so that the packets received from the legacy server (from an external ip) are port forwarded to the external ip address ip3?

• What every beginner should know about website development? [closed]

  - by user975234

  I am a novice at building websites and considering to make one. But there is a lot of confusion that's going on right now. I guess every beginner faces them. Few questions that come up are: I have an idea and a need a website. That's all i know right now. But how do i start ? HTML is for sure the basic language but there are a hell of other technologies too. What is actually asp, php, ruby etc? How do i choose the right one from them? Other than asp, php there is javascript and other languages under the same belt. What are they used for? Hosting. When i am choosing the host, what considerations i have to keep in mind ? What support do i need from them (other than getting some important space obviously!). I am considering of making the website in ruby on rails. I don't know about php and what effect it would have if i choose ruby over php. I thought about ruby just because its new and i dont want to learn some thing "not new"! :P Moreover what is a framework and how does a framework effect my development process? These three questions are just to explain my "confusion" better. There is obviously a lot more to it. Just to try to answer how the flow of website development goes keeping in mind my questions!

• Fine-tuning a LNMP stack

  - by Norman

  I'm in the process of setting up a server with 4GB RAM and 2 CPUs. The stack will be CentOS + NGINX + MySQL + PHP (with APC) and spawn-fcgi. It will be used to serve 10 Wordpress blogs, 3 of which receive about 20,000 hits per day. Each Wordpress instance is equipped with the W3 TotalCache. I have a few variables to play with: NGINX (How many worker_processes, worker_connections, etc) PHP (What parameters in php.ini should I change? What about apc?) Spawn-fcgi (Right now I have 6 php-cgi spawned. How many of them should I have?) I realize it's hard to tell without testing, but if you could please provide me with some ballpark numbers, that would be helpful too.

• MSDN / TechNet Key Importer for KeePass 2

  - by Stacy Vicknair

  If you have an MSDN account and, like me, systematically claim keys just as well as you systematically forget which keys you’ve used in which test environments! Well, in a meager attempt to help myself track my keys I created an importer for KeePass 2 that takes in the XML document that you can export from MSDN and TechNet. The source is available at https://github.com/svickn/MicrosoftKeyImporterPlugin.   How do I get my KeysExport.xml from MSDN or TechNet? Easy! First, in MSDN, go to your product keys. From there, at the top right select Export to XML. This will let you download an XML file full of your Microsoft Keys.   How do I import it into KeePass 2? The instructions are simple and available in the GitHub ReadMe.md, so I won’t repeat them. Here is a screenshot of what the imported result looks like:   As you can see, the import process creates a group called Microsoft Product Keys and creates a subgroup for each product. The individual entries each represent an individual key, stored in the password field. The importer decides if a key is new based on the key stored in the password, so you can edit the notes or title for the individual entries however you please without worrying about them being overwritten or duplicated if you re-import an updated KeysExport.xml from MSDN! This lets you keep track of where those pesky keys are in use and have the keys available anywhere you can access your KeePass database!   Technorati Tags: KeePass,KeePass 2,MSDN,TechNet

• Strategy for backwards compatibility of persistent storage

  - by Baqueta

  In my experience, trying to ensure that new versions of an application retain compatibility with data storage from previous versions can often be a painful process. What I currently do is to save a version number for each 'unit' of data (be it a file, database row/table, or whatever) and ensure that the version number gets updated each time the data changes in some way. I also create methods to convert from v1 to v2, v2 to v3, and so on. That way, if I'm at v7 and I encounter a v3 file, I can do v3-v4-v5-v6-v7. So far this approach seems to be working out well, but I haven't had to make use of it extensively yet so there may be unforseen problems. I'm also concerned that if the objects I'm loading change significantly, I'll either have to keep around old versions of the classes or face updating all my conversion methods to handle the new class definition. Is my approach sound? Are there other/better approaches I could be using? Are there any design patterns applicable to this problem?

• How to make Microsoft Keyboard special keys run osascript commands on OSX?

  - by t-a-w

  I'm trying to make (1) special key open new terminal window. I bound it to file /Users/taw/bin/new_term, which contains: #!/bin/sh exec osascript -e 'tell application "Terminal" to do script "cd ."' This does the trick, except it also opens a Terminal window with this (even though Terminal.app is configured to always close windows when processes finish): Last login: Thu Mar 11 19:41:29 on ttys000 /Users/taw/bin/new_term ; exit; ~$ /Users/taw/bin/new_term ; exit; tab 1 logout [Process completed] How do I make it all work correctly? (possibly using a way different that what I've been attempting so far)

• How to build Visual Studio Setup projects (.vdproj) with TFS 2010 Build ?

  - by Vishal

  Out of the box, Team Foundation Server 2010 Build does not support building of setup projects (.vdproj). Although, you can modify DefaultTemplate.xaml or create your own in order to achieve this. I had to try bunch of different blog post's and finally got it working with a mixture of all those posts.   Since you don’t have to go through this pain again, I have uploaded the Template which you can use right away : https://skydrive.live.com/redir?resid=65B2671F6B93CDE9!310 Download and CheckIn this template into your source control. Modify your Build Definition to use this template. Unless you have CheckedIn the template, it wont show up in the template selection section in the process task of build definition. In your Visual Studio Solution Configuration Manager, make sure you specify to build the setup project also. You might get this warning in your build result: “The project file “*.vdproj” is not support by MSBuild and cannot be build. Hope it helps. Thanks, Vishal Mody Reference blog posts I had used: http://geekswithblogs.net/jakob/archive/2010/05/14/building-visual-studio-setup-projects-with-tfs-2010-team-build.aspx http://donovanbrown.com/post/I-need-to-build-a-project-that-is-not-supported-by-MSBuild.aspx http://lajak.wordpress.com/2011/02/19/build-biztalk-deployment-framework-projects-using-tfs2010/

• A "region code" restriction for a custom created video dvd file

  - by user180820

  I want to create a video dvd ( no menus, just "plug and play" ) from a few video files. I`m doing it like this: ffmpeg -i sample-media/hellboy-2.wmv -y -target ntsc-dvd sample-media-to-mpeg/hellboy-2.vob dvdauthor -o sample-dvd -x dvdauthor-settings.xml mkisofs -dvd-video -o hellboy-2-trailers.iso sample-dvd/ where "dvdauthor-settings.xml" is: link. But when I try to play the iso file in windows it says: Windows Media Player cannot play the DVD because the disc prohibits playback in your region of the world. You must obtain a disc that is intended for your geographic region. When I open the *.IFO file with IfoEdit it says that all world regions are unabled. Can someone tell me why is this happening? ( maybe the whole process of creating the *.iso file is wrong? )

• Redirect one input from one terminal to another

  - by Niki Yoshiuchi

  I have sshed into a linux box and I'm using dvtm and bash (although I have also tried this with Gnu screen and bash). I have two terminals, current /dev/pts/29 and /dev/pts/130. I want to redirect the input from one to the other. From what I understand, in /dev/pts/130 I can type: cat </dev/pts/29 And then when I type in /dev/pts/29 the characters I type should show up in /dev/pts/130. However what ends up happening is that every other character I type gets redirected. For example, if I type "hello" I get this: /dev/pts/29 | /dev/pts/130 $ | $ cat </dev/pts/29 $ el | hlo This is really frustrating as I need to do this in order to redirect the io of a process running in gdb (I've tried both run /dev/pts/# and set inferior-tty /dev/pts/# and both resulted in the aforementioned behavior). Am I doing something wrong, or is this a bug in bash/screen/dvtm?

• Showing content from pages at different URL's (masking), possibly with .htaccess

  - by zigojacko

  If I have URL's like:- domain.com/category/widgets/filter/blue domain.com/category/widgets/filter/red And it is pretty difficult to reconstruct them to something like:- domain.com/category/blue-widgets domain.com/category/red-widgets Is there any way at all that I can use URL rewrites or anything else with .htaccess or on the server to display the URL's as the domain.com/category/blue-widgets on the domain.com/category/widgets/filter/blue page? I've looked into masking URL's but got nowhere and this has been something bugging me for almost 6 months now. Is there any way to achieve what I want to do? FYI: This is a Magento website and the above process, I am wanting to implement for potentially hundreds of URL's. Edit To respond to @kkugelmann's answer:- I couldn't get your proposed RewriteRule to make a difference at all in the .htaccess file so I started testing a few things in this .htaccess tester:- The proposed RewriteRule didn't work in this tester:- However, the following did:- But adding any of these RewriteRule's into the website's .htaccess file did not rewrite the URL at all... Edit2 By the way, if I add [R=301,L] to the end of the URL rewrite rule, it does actually then rewrite the rule, but of course 301 redirects it as well which is unwanted behaviour. Edit3 I found another question with the same issue... And an accepted answer that solved the problem which seemed to be something to do with using mod_proxy and the [P] tag on the rule (if I try this, the page 404's).

• Access Control Service: Home Realm Discovery (HRD) Gotcha

  - by Your DisplayName here!

  I really like ACS2. One feature that is very useful is home realm discovery. ACS provides a Nascar style list as well as discovery based on email addresses. You can take control of the home realm selection process yourself by downloading the JSON feed or by manually setting the home realm parameter. Plenty of options – the only option missing is turning it off… In other words, when you setup your ACS namespace and realm and register identity provider, there is no way to keep the list of identity providers secret. An interested “user” can always retrieve all registered identity provider (using the browser or download the JSON feed). This may not be an issue with web identity providers, but when you use ACS to federate with customers or business partners, you maybe don’t want to disclose that list to the public (or to other customers). This is an adoption blocker for certain situations. I hope this feature will be added soon. In addition I would also like to see a feature I call “home realm aliases”. Some random string that I can use as a whr parameter instead of using the real issuer URI.

• What are the mandatory Linux kernel modules to run inside of ESXi

  - by Marcin

  I'm used to rolling my own kernels for servers, as it nicely minimizes the number of exploits (and the resulting patches) to take care of. In a traditional (bare metal) world, the whole process is about knowing what you have (hardware), and what you need (Ethernet, IPv4, iptables, etc.) In a virtualized environment, some things stay the same (still need Ethernet and IPv4), some things go away (power management), and then there are some new needs (vxnet3, or vmware-tools, even though that's compiled outside of the kernel). So my question mostly concerns itself with the last two categories: what can I remove completely, and what new stuff do I want? For example, what IO scheduler do I want, if all my disk operations are going through another filesystem/scheduler/cache to get to the virtual disk? Do I need hyper-threading enabled, or is the VM going to show them to me anyway as a CPU anyway? Do I need Large Receive Offload turned on, or is that something that the hypervisor's network drivers are going to do for me?

• How do I install Ubuntu 13.10 from a partition on my Mac?

  - by Barry

  I am trying to install Ubuntu 13.10 on my Macbook Air. I've previously had no issue installing from a USB stick to this machine. However, I don't currently have access to a USB stick or any external media at all! What I've done so far is partitioned my SSD into 3 partitions. One holds OS X, another is a 5gb partition intended for the install ISO, and a third is intended to be the target for that install. The second two partitions are formatted as FAT. I've used dd (with and without bs=1m) to "burn" my ISO to the small 5gb FAT partition. I also at one point tried using hdituil to convert my ISO file to IMG and went through the same process with same result below. After "burning" my ISO to the small partition, I reboot into Refind. Refind sees my small 5gb partition perfectly well, and when I select that partition it loads GRUB appropriately. However, from here, regardless of what I choose, Ubuntu will start to load and then after a few minutes crash out to: BuzyBox V1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash) Enter 'help' for a list of built in commands. (initramfs) unable to find a medium containing a live file system. I've Googled this error and found a number of people encountering it when trying to install from USB, but no solutions seem applicable to my case (installing from a partition on my SSD, to another partition on my SSD). Is there any solution to this, or do I just need to wait a few days until I have access to a USB stick? Many thanks in advance, and apologies for length -- I figured I'd err on the side of being exhaustive rather than having people suggest things I've already tried.

• Automated backups for Windows Azure SQL Database

  - by Greg Low

  One of the questions that I've often been asked is about how you can backup databases in Windows Azure SQL Database. What we have had access to was the ability to export a database to a BACPAC. A BACPAC is basically just a zip file that contains a bunch of metadata along with a set of bcp files for each of the tables in the database. Each table in the database is exported one after the other, so this does not produce a transactionally-consistent backup at a specific point in time. To get a transactionally-consistent copy, you need a database that isn't in use.The easiest way to get a database that isn't in use is to use CREATE DATABASE AS COPY OF. This creates a new database as a transactionally-consistent copy of the database that you are copying. You can then use the export options to get a consistent BACPAC created.Previously, I've had to automate this process by myself. Given there was also no SQL Agent in Azure, I used a job in my on-premises SQL Server to do this, using a linked server configuration.Now there's a much simpler way. Windows Azure SQL Database now supports an automated export function. On the Configuration tab for the database, you need to enable the Automated Export function. You can configure how often the operation is performed for you, and which storage account will be used for the backups.It's important to consider the cost impacts of this as well. You are charged for how ever many databases are on your server on a given day. So if you enable a daily backup, you will double your database costs. Do not schedule the backups just before midnight UTC, as that could cause you to have three databases each day instead of one.This is a much needed addition to the capabilities. Scott Guthrie also posted about some other notable changes today, including a preview of a new premium offering for SQL Database. In addition to the Web and Business editions, there will now be a Premium edition that has reserved (rather than shared) resources. You can read about it all in Scott's post here: http://weblogs.asp.net/scottgu/archive/2013/07/23/windows-azure-july-updates-sql-database-traffic-manager-autoscale-virtual-machines.aspx

• Get Started with JavaFX 2 and Scene Builder

  - by Janice J. Heiss

  Up on otn/java is a very useful article by Oracle Java/Middleware/Core Tech Engineer Mark Heckler, titled, “How to Get Started (FAST!) with JavaFX 2 and Scene Builder.”  Heckler, who has development experience in numerous environments, shows developers how to develop a JavaFX application using Scene Builder “in less time than it takes to drink a cup of coffee, while learning your way around in the process”. He begins with a warning and a reassurance: “JavaFX is a new paradigm and can seem a bit imposing when you first take a look at it. But remember, JavaFX is easy and fun. Let's give it a try.” Next, after showing readers how to download and install JDK/JavaFX and Scene Builder, he informs the reader that they will “create a simple JavaFX application, create and modify a window using Scene Builder, and successfully test it in under 15 minutes.” Then readers download some NetBeans files:“EasyJavaFX.java contains the main application class. We won't do anything with this class for our example, as its primary purpose in life is to load the window definition code contained in the FXML file and then show the main stage/scene. You'll keep the JavaFX terms straight with ease if you relate them to the theater: a platform holds a stage, which contains scenes. SampleController.java is our controller class that provides the ‘brains’ behind the graphical interface. If you open the SampleController, you'll see that it includes a property and a method tagged with @FXML. This tag enables the integration of the visual controls and elements you define using Scene Builder, which are stored in an FXML (FX Markup Language) file. Sample.fxml is the definition file for our sample window. You can right-click and Edit the filename in the tree to view the underlying FXML -- and you may need to do that if you change filenames or properties by hand - or you can double-click on it to open it (visually) in Scene Builder.” Then Scene Builder enters the picture and the task is soon done.

• Producer-consumer pattern with consumer restrictions

  - by Dan

  I have a processing problem that I am thinking is a classic producer-consumer problem with the two added wrinkles that there may be a variable number of producers and there is the restriction that no more than one item per producer may be consumed at any one time. I will generally have 50-100 producers and as many consumers as CPU cores on the server. I want to maximize the throughput of the consumers while ensuring that there are never more than one work item in process from any single producer. This is more complicated than the classic producer-consumer problem which I think assumes a single producer and no restriction on which work items may be in progress at any one time. I think the problem of multiple producers is relatively easily solved by enqueuing all work items on a single work queue protected by a critical section. I think the restriction on simultaneously processing work items from any single producer is harder because I cannot think of any solution that does not require each consumer to notify some kind of work dispatcher that a particular work item has been completed so as to lift the restriction on work items from that producer. In other words, if Consumer2 has just completed WorkItem42 from Producer53, there needs to be some kind of callback or notification from Consumer2 to a work dispatcher to allow the work dispatcher to release the next work item from Producer53 to the next available consumer (whether Consumer2 or otherwise). Am I overlooking something simple here? Is there a known pattern for this problem? I would appreciate any pointers.

• How to monetize and protect a engine's and its framework's copyrights and patents?

  - by Arthur Wulf White

  I created a game engine that handles: Rendering levels with 2d textured curved surfaces Collisions with curved surfaces Animationn paths on and navigation in 2d-sapce I have also made a framework for: Procedural organic level generation with round surfaces Level editing Light weight sprite design The engine and framework are written in AS3 and I am in the process of translating the code into HaXe to better support other platforms. I am also interested in adding Animated curved platforms More advanced level editing features Currently, I have a part time job and any time I spend on this engine is either taken out of my limited free time (I'm a student working to support myself through school) or out my time working at my job. I really believe this engine can make life much easier for people designing Tower Defence games, Shooters and and Platformers while also possibly improving their results. It could also support RTS, RPGs and racing games very well. It continains original algorithms that could be used for procedural generation of organic round and smooth levels. The algorithms I used are new and are not available in any other level editor I've seen. In order to constantly improve the Engine and have it tested thoroughly I think the best route is releasing it to the public. What are the best ways to benefit myself and others with my new framework? I want to have some lisence, allowing me to share the framework and still benefit from it. Any advice would be appreciated. This issue has been on my mind a lot this year. I am hoping to find a solution that will bring me some relief. I am thinking of designing three sample games, releasing them and starting a kickstarter, any advice and thoughts on the matter would be valuable. My goal is like Markus von Broady suggested, to get people involved in developing the engine and let people use it for games for either a symbolic fee or for free and charge for support. That or use some form of croud sourcing. Do I need to hire a lawyer to get some sort of legal document to protect my work?

• sound clipping in windows 7 64bit

  - by Sonic Soul

  something is up with 64 bit version of windows 7. i have 2 (good pro-sumer) sound cards which i've used in other version of windows 7 w/out problems, but now it is causing severe clipping (noise, sound having little gaps surrounded by static).. the cards i am using is echo mia, and native instruments audio kontrol 1. the audio kontrol 1 is a external card, and would work ok for a few hours after rebooting, and than it would go back into clipping mode, to the point where you tube videos would not play from trying to process sound and it stopping for extended periods of time. echo mia is performing better, but there is still some clipping and distortion. the machine i use is newly built, with i7 920 64 bit cpu, 6 gigs of ram and an outdated nvidia video card (geforece 7950 gx2)
