• What software can I use to create a video of following type?

  - by Bond

  Here is a video on this link http://www.youtube.com/watch?v=kSx873lOgIc&feature=player_embedded#at=62 Someone among my bosses wants to create some thing similar to the video on above link and has asked me what software can they use to do the same.The purpose is to create educational content only.Which can have the demonstrations (animations ) and audio also running in backend. I am not clear as what software can be used for this on Linux or Windows. I have users which use Windows and Linux both. I have used video editing on Mac using Final Cut Pro but the video on the above link is not some thing which can be achieved with FCP.(Or may be I am not aware) I am looking solution for 1) Linux users 2) Windows users In case of Linux it is Ubuntu for some users and Fedora for some others. I am a Linux guy so I am specifically posting this question in terms of Ubuntu but I also need suggestions for Windows type of users.I have no clue of such video animations at all.

• Why doesn't openSUSE Linux upgrade itself through its software repositories?

  - by Dougal

  openSUSE - fast becoming my favourite Linux distro on the client - doesn't seem to upgrade itself through its own configured software repositories. Do we know why this is the case? Is it a money-making thing where they can then sell upgrade CDs / DVDs? I mean, pretty much every other Linux upgrades itself through the normal software repositories. For example, Ubuntu can upgrade itself from 10.4 to 10.10 just through the normal software package upgrade procedure. Why must it be a huge procedure to upgrade openSUSE? Any knowledge or ideas appreciated. Thank you.

• Super user in LDAP?

  - by John8894

  I am running 10 Linux machines that is doing different types of work. The machines are configured to use LDAP authentication so when one user is configured in slapd he can login on all the machines. To make maintenance easier i want to create a root account in slapd so i can use this instead of the local root accounts when installing applications etc. but i am not sure on how to do this. Is it enough to create a user with the name root and gid/uid 0? should the local root be disabled somehow? I am fully aware that this is normally not a good idea from a security perspective, but as mentioned before this is a special case.

• After reboot allocated node gets commissioned again

  - by cloudfan

  i had set up a maas with juju and deployed Openstack into it for testing. During my vacation i shut down all computers. Afterwards i started at first the maas server, then the node where juju was bootstrapped and juju-gui was deployed to. Sadly the node got commissioned again and so all my deployments are gone. I decomissioned the according node from the maas and bootstrapped it again. Afterwards i tested again juju bootstrapping the node, shutting down both nodes and starting them in the same order again. The Juju node gets commisioned again. After bootstrapping everything looked fine in the MAAS GUI (node was set to allocated to root, which was also the case after the restart) and also the JUJU GUI was available and juju status worked fine. Before my vacation i also had some other nodes deployed through juju. They all seem to be still available and have not been commisioned again. Do you have any ideas what might have happened? Is there any issue with a bootstrapped juju node and the commisioning? Any help or hints on what i could check are appreciated! Thank in advance for your help!

• How can I redirect all files in a directory that doesn't conform to a certain filename structure?

  - by user18842

  I have a website where a previous developer had updated several webpages. The issue is that the developer had made each new webpage with new filenames, and deleted the old filenames. I've worked with .htaccess redirects for a few months now, and have some understanding of the usage, however, I am stumped with this task. The old pages were named like so: www.domain.tld/subdir/file.html The new pages are named: www.domain.tld/subdir/file-new-name.html The first word of all new files is the exact name of the old file, and all new files have the same last 2 words. www.domain.tld/subdir/file1-new-name.html www.domain.tld/subdir/file2-new-name.html www.domain.tld/subdir/file3-new-name.html ect. We also need to be able to access the url: www.domain.tld/subdir/ The new files have been indexed by google (the old urls cause 404s, and need redirected to the new so that google will be friendly), and the client wants to keep the new filenames as they are more descriptive. I've attempted to redirect it in many different ways without success, but I'll show the one that stumps me the most RewriteBase / RewriteCond %{THE_REQUEST} !^subdir/.*\-new\-name\.html RewriteCond %{THE_REQUEST} !^subdir/$ RewriteRule ^subdir/(.*)\.html$ http://www.domain.tld/subdir/$1\-new\-name\.html [R=301,NC] When visiting www.domain.tld/subdir/file1.html in the browser, this causes a 403 Forbidden error with a url like so: www.domain.tld/subdir/file1-new-name-new-name-new-name-new-name-new-name-new-name-new-name-new-name-new-name-new-name-new-name-new-name-new-name.html I'm certain it's probably something simple that I'm overlooking, can someone please help me get a proper redirect? Thanks so much in advance! EDIT I've also got all the old filenames saved on a separate document in case I need them set up like the following example: (file(1|2|3|4|5)|page(1|2|3|4|5)|a(l(l|lowed|ter)|ccept)

• JDeveloper News &ndash; Did You Know

  - by shay.shmeltzer

  There have been a few issues lately with access to blogs.oracle.com to write new messages – and as a result I’m a little behind on reporting the latest and greatest in JDeveloper. (I’m also unable to approve comments :-( ) But just in case you missed it here are a few note worthy things you should know: ADF Mobile Client went production – this is a solution that let you use ADF to develop on-device applications for mobile devices. You develop once and run on various devices (right now Blackberry and Windows Mobile with other platforms coming soon). For more information check out the ADF Mobile page on OTN. ADF Developer Certification goes production – you can now take the official test and get an official certification that you can include in your resume.Should be a must for any consultant looking to get ADF related gigs. Learn more about the ADF Certification Exam. ADF Vision Stencils Released – If you are looking for a quick way to draw prototypes of ADF screens you probably can’t get any faster and more accurate results than this. This is a set of Vision components that you can drag over and design a page visually. You can also set properties for components and do other advance things. You do need a license for Visio to use this, but the ADF stencils are free. We’ve been using these internally at Oracle for some time now and we thought the ADF community would enjoy these too. Download the ADF Visio Stencils here (and watch a youtube demo of how they work).

• table alias (or 'symlink') in mysql

  - by andreash

  Hi there, in MySQL5.1, is there a way to make one table accessible by two different names? I'm thinking about somethink like a symlink on linux filesystems. I know theres the CREATE VIEW myview AS SELECT * FrOM mytable thing, but I don't only need to SELECT from both names, but also delete etc ... You might ask why I want to do this? It's about getting a commercial, closed-source app to work, which is crappily programmed (usually, the table names are all lower-case, but occasionally, they use capitalized names for the same table ...). Oh, that would be another idea: Is there a way to tell MySQL not to care about capitalization of table names (like on Windows filesystems?)? that would also do the trick ... Thanks for your insight! A.

• Boundary conditions for testing

  - by Loggie

  Ok so in a programming test I was given the following question. Question 1 (1 mark) Spot the potential bug in this section of code: void Class::Update( float dt ) { totalTime += dt; if( totalTime == 3.0f ) { // Do state change m_State++; } } The multiple choice answers for this question were. a) It has a constant floating point number where it should have a named constant variable b) It may not change state with only an equality test c) You don't know what state you are changing to d) The class is named poorly I wrongly answered this with answer C. I eventually received feedback on the answers and the feedback for this question was Correct answer is a. This is about understanding correct boundary conditions for tests. The other answers are arguably valid points, but do not indicate a potential bug in the code. My question here is, what does this have to do with boundary conditions? My understanding of boundary conditions is checking that a value is within a certain range, which isn't the case here. Upon looking over the question, in my opinion, B should be the correct answer when considering the accuracy issues of using floating point values.

• Gentoo+urxvt+terminus: How do I change font version?

  - by gaidal

  In my Debian installation I can type extended ASCII characters such as åäö by default using the terminus font, however in Gentoo I can't get it to work so far. Nothing happens when I hit those keys, like in this thread: Missing glyphs in Terminus font, how to setup a fallback font ? But in this case I know terminus supports those characters in at least some of its versions, since it's works in Debian. So what I want is to find out how to see and choose which of the many different terminus font files is being used. I set the font in the same way on both Debian and Gentoo, using URxvt*font: xft:terminus:size=xx in .Xdefaults. Both systems use en_US.UTF-8 as default locale.

• automatically change the gnome-terminal "title" for the window

  - by tom

  Hi. Trying to change the title of a current gnome-terminal (similar to the "set title" that you can do manually") The system is running Fedora 9. The HowTo Xterm-Title discusses how to set the prompt, for an xterm. Tried to implement the escape sequences with no luck. (might be something weird..) Tried to use the gconftool to dump/change/load the changed conf attributes, and again, no luck. Also, set the PROMPT_COMMAND just in case the prompt command was somehow changing the title back (which is highly doubtful) Searching the 'net indicates that a few people have tried to solve this with no luck... I'd also like to figure out how to create a new gnome-terminal with a unique specified title... once this is solved, i'l gladly create a quick writeup/post onn how to accomplish this for others... thanks

• Should I make up my own HTTP status codes? (a la Twitter 420: Enhance Your Calm)

  - by Max Bucknell

  I'm currently implementing an HTTP API, my first ever. I've been spending a lot of time looking at the Wikipedia page for HTTP status codes, because I'm determined to implement the right codes for the right situations. Listed on that page is a code with number 420, which is a custom code that Twitter used to use for rate limiting. There is already a code for rate limiting, though. It's 429. This led me to wonder why they would set a custom one, when there is already a use case. Is that just being cute? And if so, then which circumstances would make it acceptable to return a different status code, and what, if any problems may clients have with it? I read somewhere that Mozilla doesn't implement the joke 418: I’m a teapot response, which makes me think that clients choose which status codes they implement. If that's true, then I can imagine Twitter's funny little enhance your calm code being problematic. Unless I'm mistaken, and we can appropriate any code number to mean whatever we like, and that only convention dictates that 404 means not found, and 429 means take it easy.

• make gnome3 to work as I expect! [closed]

  - by gnome

  Possible Duplicate: How to revert to GNOME Classic? I don't like unity so I tried Ubuntu Gnome Remix 12.10. But I feel disappointed too. - No right click on desktop. (I know there is a way to enable it). - No icon on desktop. - I want to have "applications", "palces", "systems" on top panel as before. It just takes much more steps to arrive where I want to go in default gnome 3 settings. - It seems to me that for some applications, when it is maximalized, there is no close buttons or "restore to previous size" button. In fact, it has no title bar in this case, so I can't drag the title bar to restore its previous size and move the window. So I got 3 questions here: (for those who like the way gnome work before) What difference between gnome2 and gnome3 that you prefer the way it works in gnome2? How do you change it to work in the gnome2 way? I don't like the appearance in gnome3. For those who have tried to make your gnome3 looks good, could you share how you customize your gnome3 appearance? (this is for chatting only, not a real question) Why all the main OS (Windows, Mac, Some Linux) want to integrate Desktop and Tablet with focus on Tablet? (Which means that when it is installed on a desktop, it still has tablet appearance, which makes things strange.) Do they think the personal desktop PC will become less and less?

• Software for defining rules for folder permissions and monitoring deviations

  - by Kjensen

  Let's say a company has a large number of users, and each user has a home area. On each share used for home area folders, I would like to define some rules saying who is supposed to have which permissions on the folder. Then I would like to audit automatically, that this is actually the case and get some sort of report on deviations. So a rule for \MegaServer\Home01 could be defined something like: Domain Admins - Full Control Backup Agent - Read [Home folder owner] - Full Control I am talking about Windows platform and Windows servers, although I think it would most likely also work for *nix machines that expose Windows shares. Does software like this exist? I could roll my own basic version, but if something already exists, that is usually a better option. I am aware of tools to make displaying permissions easier (AccessEnum, DumpSec), but that is not what I am looking for.

• BackupPC - are full backups really full when using rsync?

  - by mhost

  Hi, When you run a full backup in backuppc and you use rsync as the transfer method, does it actually transfer the full backup source? Or does it only transfer the changes? The docs seem to imply that it would transfer the full thing and only an incremental would transfer the changes. If this is the case, could I simply use incrementals only, and never do a full backup? The way the backups are stored (using hard links to make each incremental appear full), I would think that this would be the best method. Incrementals will only transfer the changes, yet each backup will appear full. Thanks.

• Advanced TSQL training

  - by Dave Ballantyne

  Over the past few years, Ive had it on my to do list to write and deliver and full-scale SQLServer training course and not just an hour long bite size session at user groups and conferences.  To me, SQLServer development is not just knowing and remembering the syntax of commands.  Sometimes I semi-jest that i have “Written a merge statement without looking up the syntax”, but I know from my interactions on and off line that I am far from alone in this.  In any case we have an awesome tool in the internet which is great at looking things up. When developing SQL Server based solutions,  of more importance is knowing the internals of the engine.  SQL Server is a complex piece of software and we need to be able to understand to a fairly low level ( you can always dive deeper ) the choices that it makes and why it makes them in order to deliver performant, reliable, predictable and scalable systems to our customers and end-users. This is the view i shall be taking over two days in March (19th and 20th) in London and ,TBH, one I dont see taken often enough. Early bird discounts are available until 31Dec. Full details of the course and a high level view of the bullet points we shall be covering are available at the Technitrain site ( http://tinyurl.com/TSQLTraining )

• Conventions for search result scoring

  - by DeaconDesperado

  I assume this type of question is more on-topic here than on regular SO. I have been working on a search feature for my team's web application and have had a lot of success building a multithreaded, "divide and conquer" processing system to work through a large amount of fulltext. Our problem domain is pretty specific. Users of the app generate posts, and as a general rule, posts that are more recent are considered to be of greater relevance. Some of the data we are trying to extract from search is very specific (user's feelings about specific items or things) and we are using python nltk to do named-entity extraction to find interesting likely query terms. Essentially we look for descriptive adjective-noun pairs and generate a general picture of a user's expressed sentiment as a list of tokens. This search is intended as an internal tool for our team to draw out a local picture of sentiments like "soggy pizza." There's some machine learning in there too to do entity resolution on terms like "soggy" to all manner of adjectives expressing nastiness. My problem is I am at a loss for how to go about scoring these results. The text being searched is split up into tokens in a list, so my initial approach would be to normalize a float score between 0.0-1.0 generated off of how far into the list the terms appear and how often they are repeated (a later mention of the term being worth less, earlier more, greater frequency-greater score, etc.) A certain amount of weight could be given to the timestamp as well, though I am not certain how to calculate this. I am curious if anyone has had to solve a similar problem in a search relevance grading between appreciable metrics (frequency, term location/colocation, recency) and if there are and guidelines for how to weight each. I should mention as well that the final fallback procedure in the search is to pipe the query to Sphinx, which has its own scoring practices. Sphinx operates as the last resort in case our application specific processing can't find any eligible candidates.

• Advertising on personalized pages behind a login

  - by johneth

  I am currently building a web app which requires a user to log in. After they log in, they can see the content they've added to the web app, and things that the web app has done with the content they added. The URL structure won't differentiate different users (e.g. all user's 'homepage' would be example.com/home, not something like example.com/username/home). This is much the same way that Facebook works (all FB user's messages are at facebook.com/messages, for example). This presents a problem with advertising. I know that you can use AdSense behind a login, but as far as I'm aware, that's for things like forums, where everyone sees the same things (which wouldn't be the case in this site). I also know that I could put AdSense on the pages without allowing it to log in, which would produce inferior ads. I'm fairly certain it would be against the Terms of Service to give AdSense a login to a 'dummy' account with typical content, as it would not be seeing the same thing as every other user (which is impossible, as they all see different things). So, my question is: Is there an ad network, or other method, that can serve ads behind a login, maybe based on keywords rather than content?

• Find methods related to testcases in Java

  - by user3623718

  I want to automatically change some methods in the program. These methods contain some compiler error and my program aims to fix these compiler errors. After fixing compiler errors I need to run test cases related to the changed method (or class) to know it is correct and if not which test cases failed. As the programs under investigation are very big, I only need to run test cases related to changes. As an example, if I change one method, then I need to only run test cases related to this method. Therefore, what I need is to programmatically be able to find test cases related to each method, and class. It is also useful if there is a tool that can do that for me. As an example, a tool which creates a matrix shows each test case is related to which method(s) One easy way to do that is to run all test cases and save functions they accessed. However, the problem is at the beginning the input program contains compiler error and it is not possible to run test cases because of these compiler error. Please let me know what is the best way to do that. An API or a tool that I can be used programmatically is the best for me.

• Read the contents of a ComboBox (or any other windows control) [closed]

  I have a program that reads the contacts from my phone, but I can't export them from it. I'd like to use another program to read the contents of the controls on the original program. In this case, I would like to export the content of a dropdown list (combobox), containing these contacts. Can someone recommend a good program for this or recommend another method? I know I saw something for this last year on lifehacker.com in a collection of diagnostic tools, but I can't find it now.

• Share files - Ubuntu 12.4 and Windows 7 - one network - password not accepted

  - by gotqn

  I have three machines - two with windows 7 and one with Ubuntu 12.4 version. There are in the same network connected by modem. The two machines shares file with no problem, but they can not see the machine with Ubuntu. On the other hand, I am able to see the share files of the windows machines from the Ubuntu's Network. When I select a folder, it wants the network password - I changed it several times in order to be sure that I am entering the correct one but in every case it says that the password is wrong. I have read some topics about files sharing between Linux and windows in which it is said that I should use samba, but is there a more easy way to do this, using the build it options?

• Lots of Internet browsing issues, all browsers

  - by dario_ramos

  Before the upgrade, everything was working fine. Now, however, I can connect to the Internet but a lot of stuff fails, and the weirdest thing is that it happens with Firefox, Chromium and Opera. Some of the things that fail: I can't log in to Stack Overflow, after entering user/pass it loads for a long time on Firefox and throws Error 408 (browser request timed out) on Chromium and Opera I can't log in to Hotmail, similar symptoms I can login to Facebook, but when I try to write a comment, or just post something in my wall, it stays loading for a long time, and then fails The first two issues seem to be related to secure pages, and the second one is another issue altogether, I believe. However, they all happen with all browsers, which is really weird. Talking about weird: I connect using a Huawei SmartAX MT 810 USB modem, which cost me blood and tears to get it working under Ubuntu. I ordered an ethernet modem/router with my ISP, and I'm still waiting, but this issue intrigues me anyway. Has anyone experienced this kind of problems? I Googled around, but couldn't find a similar case.

• What is a "good" tool to password-protect .pdf files?

  - by Marius Hofert

  What is a "good" tool to encrypt (password protect) .pdf files? (without being required to buy additional software; the protection can be created under linux but the password query should work on Windows, too) I know that zip can do it: zip zipfile_name_without_ending -e files_to_encrypt.foo What I don't like about this is that for a single file, you have to use Winzip to open the zip and then click the file again. I rather would like to be prompted for a password when opening the .pdf (single file case). I know that pdftk can do this: pdftk foo.pdf output foo_protected.pdf user_pw mypassword. The problem here is that the password is displayed in the terminal -- even if you use ... user_pw PROMPT. But in the end you get a password-protected .pdf and you are prompted for the password when opening the file.

• Understanding interfaces [closed]

  - by user985482

  Possible Duplicate: When to use abstract classes instead of interfaces and extension methods in C#? Why are interfaces useful? What is the point of an interface? What other reasons are there to write interfaces rather than abstract classes? What is the point of having every service class have an interface? Is it bad habit not using interfaces? I am reading Microsoft Visual C# 2010 Step by Step which I feel it is a very good book on introducing you to the C# language. I have just finished reading a chapter on interfaces and although I understood the syntax of creating and using interfaces I have trouble of understanding the point on why should I use them? Correct me If I am wrong but in an interface you can only declare methods names and parameters.The body of the method should be declared in the class that inherits the interface. So in this case why should I declare an interface if I am going to declare the entire method in the class that inherits that interface? What is the point? Does this have something to do with the fact that a class can inherit multiple interfaces?

• Several border firewalls in the same network

  - by nimai

  I'm currently analyzing the consequences of multipath connections for the firewalls. In that context, I'm wondering if it's really uncommon to have several firewalls at the borders of a network to protect it. The typical case I'd imagine would be a multihomed network, for which the administrator would have different policies for links from different (or not) ISPs. Or maybe even in an ISP's network. What would be the practical (dis)advantages of such a configuration? Could you provide an example of an existing topology using several border firewalls?

• How to tell start-stop-daemon to update $HOME and $USER accordingly to --chuid parameter

  - by iElectric

  I'm trying to run a service that uses $HOME and $USER environment variables. I could set them in service itself, but that would only be a temporary solution. Let's say I have a script test.sh with following content: echo $USER And I run it with start-stop-daemon to see my results: $ start-stop-daemon --start --exec `pwd`/test.sh --user guest --group guest --chuid -guest root Seems like it does not update environment, maybe that should be reported as a bug? I have found a nasty hacky solution, which only works (for unknown reason) on my this simple use case: $ start-stop-daemon --exec /usr/bin/sudo --start -- -u guest -i 'echo $USER' guest I'm sure someone else stumbled upon this, I'm interested in clean solution. $ start-stop-daemon --version start-stop-daemon 1.13.11+gentoo
