  • Network connection via USB

    - by Fco
    Can I get my Nexus One/Android on my local network over USB instead of WiFi and browse to my computer's IP address, the one to which the phone would be connected to, via USB? For instance, let's say my computer has an IP address 100.1.1.1 and when I go to it from the computer I would go to my localhost and see a website I've set up locally in the computer. Then, I connect my phone to that computer via USB. Can I then go to 100.1.1.1 from the browser and see the same website? All this through the USB, no WiFi?

  • How do web servers enforce the same-origin policy?

    - by BBnyc
    I'm diving deeper into developing RESTful APIs and have so far worked with a few different frameworks to achieve this. Of course I've run into the same-origin policy, and now I'm wondering how web servers (rather than web browsers) enforce it. From what I understand, some enforcing seems to happen on the browser's end (e.g., honoring a Access-Control-Allow-Origin header received from a server). But what about the server? For example, let's say a web server is hosting a Javascript web app that accesses an API, also hosted on that server. I assume that server would enforce the same-origin policy --- so that only the javascript that is hosted on that server would be allowed to access the API. This would prevent someone else from writing a javascript client for that API and hosting it on another site, right? So how would a web server be able to stop a malicious client that would try to make AJAX requests to its api endpoints while claiming to be running javascript that originated from that same web server? What's the way most popular servers (Apache, nginx) protect against this kind of attack? Or is my understanding of this somehow off the mark? Or is the cross-origin policy only enforced on the client end?

  • Mac OS X: easiest (free, non-QuickTime Pro) application for converting numbered folder of images to movie

    - by Jared Updike
    I'd like to convert a folder of PNGs into a quicktime .mov with PNG compression (it's a folder of fractals in an animation; PNG compression works great here and the losslessness is important). What programs will do this with minimal fuss? (I don't have or want to pay for a full license of QuickTime Pro.) UPDATE: Let me make this more clear: minimal fuss means: I download some EncoderMagic.app (for example), I double click it to launch it. I select the folder with my numbered images, and out pops my movie. No mess. No resizing. ... Perhaps this doesn't exist (or is called QuickTime Pro?)

  • Lubuntu 12.10: Icon Display Problems

    - by SlcBullseye
    First off, I would like to let you know that I am new to Linux. I finally decided to give it a try and my first project was installing Lubuntu on an old PC and using it for a media server for my PS3. So, one thing that I noticed right away is that my icons for applications, files, folders, etc...are not visible. If I move my mouse over the name of the application or file (It only works if I move the mouse up from the bottom of the name) then the icon will appear, but if I move my mouse back over any other place on the file the icon will disappear again. Also, if I open a folder sometimes an icon or two will be displayed but the rest won't, and like I said before if I move my mouse over the top of the application or file the icon will disappear. Is there any way to fix this? Is this normal? Or could it be a problem with my hardware? I never had this issue when I was running the last OS (Windows XP). Any help would be greatly appreciated. Remember, I am new to Linux so a thorough explanation would be helpful. Also, if there are any tips, tricks, references, or recommendations any of you have to help me jump in and become more familiar with using Linux that would be great! I'm very interested in taking advantage of the power Linux has. Currently I am studying computer programming so maybe one day I will be able to develop my own Linux distribution.

  • ADF Logging In Deployed Apps

    - by Duncan Mills
    Harking back to my series on using the ADF logger and the related  ADF Insider Video, I've had a couple of queries this week about using the logger from Enterprise Manager (EM). I've alluded in those previous materials to how EM can be used but it's evident that folks need a little help.  So in this article, I'll quickly look at how you can switch logging on from the EM console for an application and how you can view the output.  Before we start I'm assuming that you have EM up and running, in my case I have a small test install of Fusion Middleware Patchset 5 with an ADF application deployed to a managed server. Step 1 - Select your Application In the EM navigator select the app you're interested in: At this point you can actually bring up the context ( right mouse click) menu to jump to the logging, but let's do it another way.  Step 2 - Open the Application Deployment Menu At the top of the screen, underneath the application name, you'll find a drop down menu which will take you to the options to view log messages and configure logging, thus: Step 3 - Set your Logging Levels  Just like the log configuration within JDeveloper, we can set up transient or permanent (not recommended!) loggers here. In this case I've filtered the class list down to just oracle.demo, and set the log level to config. You can now go away and do stuff in the app to generate log entries. Step 4 - View the Output  Again from the Application Deployment menu we can jump to the log viewer screen and, as I have here, start to filter down the logging output to the stuff you're interested in.  In this case I've filtered by module name. You'll notice here that you can again look at related log messages. Importantly, you'll also see the name of the log file that holds this message, so it you'd rather analyse the log in more detail offline, through the ODL log analyser in JDeveloper, then you can see which log to download.

  • Triggering GDM login on a remote machine

    - by creator
    I have to briefly describe the situation. We are planning to make a computer classroom with workstations running Ubuntu 10.04. Since making accounts for each student has not been considered reasonable, we decided to make accounts for each student group. We don't want students to share their passwords between groups so the solution would be not to give them passwords at all, but let the teacher log them in instead. Obviously he shouldn't go from one machine to another typing in credentials by hand, so we need some script that will connect to a remote machine by ssh and make GDM (or probably any other login manager if GDM cannot serve this purpose) log in specified user. I couldn't find any solutions, as well as I haven't noticed anybody in similar situation asking for help, so my question will be: can the scheme described be realized and if yes, then how? Thanks in advance.

  • Is this a good implementation of a loop in Prolog?

    - by Carles Araguz
    First of all, let me tell you that this happens to be the first time I ask something here, so if it's not the right place to do so, please forgive me. I'm developing a rather complex software that has a Prolog core implementing a FSM. Since I don't want it to stop (ever), I'm trying to write a good loop-like predicate that would work using Prolog's recursion. After a few unsuccessful tries (mainly because of stack problems) I ended up having something similar to this: /* Finite State Transition Network */ transition(st0,evnt0,st1). transition(st1,evnt1,st2). transition(st2,evnt2,st0). fsm_state(state(st0),system(Energy,ActivePayloads),[]) :- /* ... */ transition(st0,evnt0,NextState), !, fsm_state(state(NextState),system(Energy,ActivePayloads),[]). fsm_state(state(st1),system(Energy,ActivePayloads),[]) :- /* ... */ transition(st1,evnt1,NextState), !, fsm_state(state(NextState),system(Energy,ActivePayloads),[0,1,2]). fsm_state(state(st2),system(Energy,ActivePayloads),[P|Params]) :- /* ... */ transition(st2,evnt2,NextState), !, fsm_state(state(NextState),system(Energy,ActivePayloads),[]). start :- Sys = system(10,[]), fsm_state(state(s0),Sys,[]). Is this a good approach?

  • How can I edit unuusal clipboard content? [on hold]

    - by Peter Jaric
    I'd like to edit application specific clipboard content, with an application specific format. There are clipboard managers that let me edit the plain text content, but I'd like to access clipboard content that application use for internal cut and paste. An example would be when you copy something from a web page in Firefox. When you look at the different formats in a clipboard viewer, there are three or so formats starting with "moz", with content that is not plain text. I'd like to edit that content before pasting it back into Firefox. Can this be done?

  • grep/search for multiple lines in a file.

    - by GSto
    Let's say I have a file with a long nested array, that's formatted like this: array( 'key1' => array( 'val1' => 'val', 'val2' => 'val', 'val3' => 'val', ), 'key2' => array( 'val1' => 'val', 'val2' => 'val', 'val3' => 'val', ), //etc... ); what I would like to do is have a way to grep/search a file, and by knowing key 1, get all the lines (the sub-array) it contains. is this possible?

  • Can you have multiple PHP 5.x versions with cPanel 11.3x?

    - by atomicguava
    I've been Googling around for a while on this one but I haven't found a good answer yet! Is it possible to set up cPanel 11.3x so that it can run different versions of PHP 5.x (e.g. 5.2, 5.3 and later on 5.4) for each of the configured apache vhosts / domains? It would be great to do this either using .htaccess, php.ini or a setting within cPanel itself. I've seen EasyApache 3 mentioned in the documentation but even after reading through several times I haven't seen a definitive yes or no for whether this is possible - please let me know if you need any more info. This was the documentation I found for EA3: http://goo.gl/IH1sP

  • Android: Not able to experiment on own?

    - by user221287
    I have just started learning Android App Development a few days ago, with prior knowledge of C/C++, HTML and CSS. This is the situation I am facing Repeatedly: I am learning from a Video Tutorial Series, after each video, or each few videos, I say myself: Let's use what I have just learnt in the simple (and also "meaningless") app that I have made so far by watching the tutorials. I start implementing it, but then after a few minutes, I realize that I cannot do it because I do not know a few other syntax related to the particular thing, (or) I do not know whether these things can be combined with these other things by the use of . (dot). Whatever I try, I get either an error in eclipse or "Sorry...the app com.example.simple has stopped unexpectedly...." when the app runs. Then I search StackOverflow, Google and learn that what I want to implement requires learning about a few more classes, syntax and creating a few more java classes. I am not able to experiment on my own. Is it normal? Is it the HARD-WAY in which one is supposed to learn? Should I first learn Java and then come back to Android - would that be helpful?

  • Best method to implement a filtered search

    - by j0N45
    I would like to ask you, your opinion when it comes to implement a filtered search form. Let's imagine the following case: 1 Big table with lots of columns It might be important to say that this SQL Server You need to implement a form to search data in this table, and in this form you'll have several check boxes that allow you to costumize this search. Now my question here is which one of the following should be the best way to implement the search? Create a stored procedure with a query inside. This stored procedure will check if the parameters are given by the application and in the case they are not given a wildcard will be putted in the query. Create a dynamic query, that is built accordingly to what is given by the application. I am asking this because I know that SQL Server creates an execution plan when the stored procedure is created, in order to optimize its performance, however by creating a dynamic query inside of the stored procedure will we sacrifice the optimization gained by the execution plan? Please tell me what would be the best approach in your oppinion.

  • Learn as much as possible about the setup behind a website.

    - by carrier
    Let's say I'm in the process of planning the setup of a website. I study similar sites that offer similar services or might receive similar traffic model. Is there a way to determine a bit the kind of setup, software and/or hardware. Some things are obvious. If I see .php or .jsp then I already know a bit. But any ideas on how to decipher more? Maybe where the site is hosted, hardware, platforms...

  • Own mediawiki/wikipedia naming convention for pages

    - by Andy M
    I recently installed a mediawiki at home and I'm looking for a way to name pages. Let's say I have the following structure : Main - Dev - C# - Tips Main - Cooking - Mexixan Cooking - Tips Main - Annoying my girlfriend - Tips Each final page is a different Tips page. Naming them only "tips" won't work because I need three different pages. Now, I could name each of my tips page with its "path" (ex: main_cooking_mexican_cooking_tips) but it looks cumbersome and the problem is that, whenever I'll change the structure of my mediawiki, some pages will need to change their name in order to be corrects. Does it exist some convention to follow regarding this ? Thanks for your help !

  • Which Microsoft server applications are compatible with Windows Server 2012? [closed]

    - by Massimo
    As mush as I personally find the new user interface to be absolutely awful (and even more so on a server O.S.), we'll soon have to put up with Windows Server 2012 (formerly Windows Server 8). So, let's start with the basics: which Microsoft products do actually run on it? I've been looking around for a compatibility chart for a while, but couldn't find one. On the requirements/support pages for various Microsoft products (even for the latest releases), Windows Server 2012 is never mentioned at all. So, what about... SQL Server Exchange Lync SharePoint System Center (CM, OM, DPM, VMM...) And so on?

  • Controlling TV Channel Through Computer

    - by killianmcc
    I'm passing my TV input through my computer so that I can use the video stream in an application I'm creating which then outputs to my TV. E.g. Sky Digibox/FreeView box - Laptop - TV Where on my laptop I'll be using the stream in a WPF application so I can overlay XAML objects onto it. My question is, what would be the best way for me to send the signal back to the box to say change the channel for example? I don't want to have to use the remote, I want the computer to handle everything. Is there a standard cable these boxes have that could take what would normally be a remote control signal and use that as input instead? Or would I have to go down the route of looking at some sort of Infared LED to send the signal recreating the remote? Apologies if this is not clear enough, let me know and I'll try and be more precise.

  • An algorithm for finding subset matching criteria?

    - by Macin
    I recently came up with a problem which I would like to share some thoughts about with someone on this forum. This relates to finding a subset. In reality it is more complicated, but I tried to present it here using some simpler concepts. To make things easier, I created this conceptual DB model: Let's assume this is a DB for storing recipes. Recipe can have many instructions steps and many ingredients. Ingredients are stored in a cupboard and we know how much of each ingredient we have. Now, when we create a recipe, we have to define how much of each ingredient we need. When we want to use a recipe, we would just check if required amount is less than available amount for each product and then decide if we can cook a dinner - if amount required for at least one ingredient is less than available amount - recipe cannot be cooked. Simple sql query to get the result. This is straightforward, but I'm wondering, how should I work when the problem is stated the other way round, i.e. how to find recipies which can be cooked only from ingredients that are available? I hope my explanation is clear, but if you need any more clarification, please ask.

  • Context Sensitive JTable (Part 2)

    - by Geertjan
    Now, having completed part 1, let's add a popup menu to the JTable. However, the menu item in the popup menu should invoke the same Action as invoked from the toolbar button created yesterday. Add this to the constructor created yesterday: Collection<? extends Action> stockActions =         Lookups.forPath("Actions/Stock").lookupAll(Action.class); for (Action action : stockActions) {     popupMenu.add(new JMenuItem(action)); } MouseListener popupListener = new PopupListener(); // Add the listener to the JTable: table.addMouseListener(popupListener); // Add the listener specifically to the header: table.getTableHeader().addMouseListener(popupListener); And here's the standard popup enablement code: private JPopupMenu popupMenu = new JPopupMenu(); class PopupListener extends MouseAdapter { @Override public void mousePressed(MouseEvent e) { showPopup(e); } @Override public void mouseReleased(MouseEvent e) { showPopup(e); } private void showPopup(MouseEvent e) { if (e.isPopupTrigger()) { popupMenu.show(e.getComponent(), e.getX(), e.getY()); } } }

  • Upgrading Blog to WordPress, keep old one or redirect?

    - by Spazm
    I have had a blog for around 4 years now that has gained some success and gets tons of residual and organic traffic. I am using an outdated version of BlogEngine.NET and we are going to switch to WordPress. Currently, our blog is at ourwebsite.com/blog, and I don't really want to mess with our web server. I setup a new server just for WordPress and instead of dealing with proxies and things that are above my head, the new blog will be at blog.oursite.com. I am trying to figure out the best way to go about doing this. We value our search engine rankings very much so, as that is where 90% of our traffic comes from. Would I be best off: Importing all of the old blog posts from oursite.com/blog to blog.oursite.com and then redirecting all of the articles, categories, authors, pages and tags to the new blog and giving up the direct links to our current site. Keeping all of our current articles as they are, and only add new content to the new blog.oursite.com and just kind of let the old blog float around our site.

  • USB 3 to Gigabit Ethernet adapters: where are they?

    - by intuited
    I'm looking for an adapter that will let me use a USB 3 port as a Gigabit Ethernet port. This is proving surprisingly hard to find! Is there some reason why this product is either unavailable or very obscure? Is there an online shop (US/Canada) where I can buy such an item? Newegg, TigerDirect, NCIX, etc. do not seem to carry such an item. I find this surprising since it will provide at least double the bandwidth (possibly quadruple) compared to a USB 2 Ethernet adapter.

  • Run a service after networking is ready on Ubuntu?

    - by TK Kocheran
    I'm trying to start a service that depends on networking being started, whenever the computer is rebooted. I have a few questions: Is this easily possible from an /etc/init.d script? I have tried creating a script here (conforming to the standards), but I'm really doubtful that it's even running on boot, let alone working. When I test it manually, it works. I've seen the new Upstart service, but as far as how that actually works, I'm completely in the dark. How can I make a script that runs on boot which runs after networking has been started? If I could run it after connected to wireless network, even better :)

  • Does connecting to the default host via public IP from within its subnet cause any issues?

    - by username
    I'm setting up a small office network with a single public IP (let's say it's 69.16.230.117). I've configured NAT on the router with incoming traffic forwarded to the server (say the server has a private IP of 192.168.0.2). Is it okay to configure the client machines on the same subnet to access the server via the router's public IP (69.16.230.117)? In practice it's never caused me problems, but I've heard, here and there, that it is a bad idea, and one should use the private IP (192.168.0.2). Does connecting to the default host via public IP from within its subnet cause any issues? Please refrain from writing "never! it breaks the intranet!" ;-)

  • Does searching a keyword on Google make the crawlers look harder in the future?

    - by Foo Bar
    Do the search requests made by the users influence the Google crawlers "attraction" by this keyword? Let's say Google has some hits on a specific keyword in the search index. And now I search for exactly this keyword. Will the Google crawlers react to the search and keep looking more intense for pages that could match this keyword? A reason why this could be important: Privacy when searching yourself. Assume you just want to know how much Google (and thus other people) can find out about you. If now any (statistical) additional search for your name trigger the crawlers even one step harder to find even more about you, it would have the negative effect that you would actually be found easier in the future, even though you had the intention and hope to find out how few Google finds about you. It's a bit like the dillema in quantum mechanis: Does observing the system automatically change the system?
