  • Ubuntu 12.10 "Turn screen off when inactive for: Never" still turns off

    - by Will
    After a fresh install of Ubuntu 12.10, my screen still goes off after about ten minutes. I've been to the Brightness and Lock control panel. The Turn screen off when inactive for: setting is set for Never. I've been through the dconf Editor searching for power, screen, and idle changing parameters. This doesn't seem to have any effect on the display timeout. Here's one more interesting thing, the screen doesn't go off, per se. It just goes black. Meaning, the back lighting is still on, and all the pixels are black. When it goes black, it does a very pleasant quick dim to black. Similarly, it quickly un-dim's after a key press, mouse movement, or mouse click. So, I'm feeling this is more of a software setting the timeout, not a power saving function.

  • How to negate current window in gnome shell?

    - by k0pernikus
    I dislike that most websites use a black font on white background for their sites, as it gets too tiresome for me to read. Back in the days of 11.04, using Gnome2 with compiz, there actually was a Negative feature that could negate the content of any window, making the background black and the font white. Much easier on the eyes for me. Yet since 11.10, using gnome shell with mutter, I have no idea if there is something alike out there. Hence my question: How do I negate the currently active window in gnome shell? I am not interested in alternative methods, e.g. user styles. I am aware of their existence but I find it much easier to just invert the screen by the hit of a key shortcut. I also want the solution to be application-agnostic. As I also from time to time would want to invert libre-office or some other glaringly white application.

  • Git does not ask for passphrase during pull/push in terminal

    - by Damian
    I'm trying to use git from the terminal in my Ubuntu 12.04 desktop. My repository is hosted in Github, and I have the a key for my desktop. Whenever I do either "git pull" or "git push," a dialog box will pop up asking for my passphrase. This works fine if I type the passphrase correctly. However, if I'm connected to my desktop through ssh and do a git pull or push, the command does not prompt the passphrase and it outputs the following error: Permission denied (publickey). fatal: The remote end hung up unexpectedly This error makes sense because I'm not inputting my passphrase. So the question is, how can I get the passphrase prompted in the terminal? Thanks!

  • Enterprise Trade Compliance: Changing Trade Operations around the World

    - by John Murphy
    We live in a world of incredible bounty and speed where any product can be delivered anywhere on earth. However, our world is also filled with challenges for business – where volatility, uncertainty, risk, and chaos are our daily companions. To prosper amid the realities of this new world, organizations cannot rely on old strategies; they need new business models. Key trends within the global economy are mandating that companies fully integrate global trade management best practices within broader supply chain management strategies, rather than simply leaving it as a discrete event at the end of the order or procurement cycle. To explain, many companies face a complicated and changing compliance environment. This is directly linked to the speed and configuration of the supply chain, particularly with the explosion of new markets, shorter service cycles and ship times, accelerating rates of globalization and outsourcing, and increasing product complexity and regulation.

  • Screen Brightness not adjustable for Acer Aspire S3

    - by Kakadu90
    First of all, thank you very much for providing this useful forum. Too bad for me, there is no support for the Acer Aspire S3 yet (just came out in October) Short Description of the Problem: I cannot adjust the screen brightness. Neither Compiz nor the FN Key combination work. Also the fan keeps running on full power. As you can guess, both of these drain my battery. The Setup: Acer Aspire S3, Intel i5 newest Generation, Intel HD3000 Grafic Accelerator (no driver maybe?) Thanks in advance, Kakadu90

  • How to get Multimedia keys working at my ASUS N56VZ Ubuntu 12.04 Notebook

    - by linuxrecon
    I don't get my multimedia keys (FN Keys) working. The Notebook is a ASUS N56VZ. If I normally press the multimedia key combinations, nothing happens. If I try to get the keycodes while pressing, for e. g., FN+F8 (this should turn volume up) with xev or acpi_listen started, there is no output at all. Only the FN+F1 (Standby) and the FN+F2 (Wireless on/off) combinations are working, but also, there is no output at xev or acpi_listen, while doing this. What can I do here?

  • What makes it hard to protect from hacks/bots in BF3 and Quake Live?

    - by Jakub P.
    After playing these games, asking other players/admins, and reading online I am led to believe that Quake Live and Battlefield 3 are frequented by bots and there are plenty of hacks of various kinds. I'm confused how this is possible, or even easy seeing how many players have access to these kinds of "tools" (sic). Isn't it possible for the game authors to digitally sign the game executables so that when they run, the server can ensure only the allowed client is sending commands, thus preventing any kind of abuse? I.e. every player command would be signed by a private key, or symmetrically encrypted (not sure which would make more sense). I understand that players can look at the running executable's behavior (memory etc.), but if games are apparently so easy to hack, shouldn't most apps be hacked as well (e.g. Skype, all DRM running on Windows etc.)?

  • Programmatically adding metatags to Masterpages in Web Forms and MVC [migrated]

    - by Mike Clarke
    Has anyone got any ideas on where we should be adding our SEO metadata in a Web Forms project? Why I ask is that currently I have two main Masterpages, one is the home page and the other one is every other page, they both have the same metadata that’s just a generic description and set of key words about my site. The problem with that is search engines are only picking up my home page and my own search engine displays the same title and description for all results. The other problem is the site is predominantly dynamic so if you type in a search for beach which is a major categories on the site you get 10000 results that all go to different information but all look like a link to the same page to the user. edit It's live here www.themorningtonpeninsula.com

  • How to change keyboard layout?

    - by swedishhh
    I'm on ubuntu 12.04. Recently I bought a cheap apple style bluetooth keyboard. It pairs OK. I paired it with the current 102 key still attached. Anyway I noticed that the character mapping is incorrect. Most keys do not type anything - some keys on the right (k, l, ;') etc give numbers, but that's about it. So I rebooted, with 102 kbd unattached, and the bluetooth keyboard on, ready to connect. After boot at the login screen, the bluetooth keyboard had paired. I typed my password, and it logged in fine!! However after the user login was complete it reverted to the broken behaviour. A glance at the layout chart shows ubuntu thinks I still have the 102 layout, even though it remained disconnected. Any ideas? Thanks, Dave

  • How to configure extra buttons in Logitech Mouse

    - by Rick
    Can anyone tell me how to configure all the buttons on a Logitech MX 620 mouse (http://www.logitech.com/en-us/support/mice/2987) under Ubuntu 12.04? Specifically, I like to make one of them just the ctrl key (for control clicking webpages) and another one ctrl-w to close tabs. I also normally make the scroll wheel page down for each click (otherwise it hurts my arms to be scrolling so much). I make pushing the wheel to the left = pageback and pushing to the right = page forward. I've searched for other answers to this and found something related here: http://ubuntuforums.org/showthread.php?t=1789807 But when I posted a followup post to solve the issue, no one responded --perhaps I made the mistake of posting to a question that had been "solved." I'm not sure how I'm supposed to reopen a question that is pertinent to my question but doesn't quite solve mine. Thank you for any help.

  • What are safe keys to remap in vim?

    - by Weeble
    So far I've been trying to use Vim in as vanilla a configuration as possible, so as to save myself hassle when moving between machines. However, there are a few things I'd really like to bind keys, such as to shorten "_diwP which I use often to delete the word under the cursor and replace it with one from the clipboard. Are there any particular keys that are conventionally reserved for user-defined mappings? The point of this question is mostly that I would like to avoid hassle later on when I decide to install some plugin or take my configuration files to vim on another OS and find that my key mappings clash with something else.

  • Event Driven Communication in Game Engine - Yes or No?

    - by Bunkai.Satori
    As I am reading book Game Coding Complete (http://www.amazon.com/Game-Coding-Complete-Third-McShaffry/dp/1584506806/ref=sr_1_1?ie=UTF8&qid=1295978774&sr=8-1), the author recommend Event Driven communication among the all game objects and modules. Basicaly, all the living game actors and object should communicate with the key modules (Physics, AI, Game Logic, Game View, etc..) via internal event messaging system. This would mean designing efficient event manager as well. My question is, whether this is proven and recommended approach. If it is not properly designed, it might mean consuming a lot of CPU cycles, which can be used elsewhere. This is especially true, if the game is targetted for mobile platform. What is your opinion and recommendation, please?

  • Is there a real name policy in the Ubuntu community?

    - by martin001
    I'm not ashamed to be a part of Ubuntu, but I'm trying to keep the number of web search hits for my real name low, which is kinda impossible if you use a Launchpad account. So, I'm wondering if there is a real name policy in the Ubuntu community, or if it's okay to use a pseudonym/nick name/fake name? While it might be okay to use nick names on IRC and in forums, how about these topics: Adding an OpenPGP key to Launchpad. Signing the Ubuntu Code of Conduct. Becoming an Ubuntu member. Code contributions (e.g., signing the Canonical CLA). Thanks in advance for your answers!

  • How do I reset my Ubuntu user password?

    - by Myself
    I lost my Ubuntu user account password... I saw some other questions on this topic that had answers telling me to restart the computer, press the left shift key after BIOS, go to root, type "passwd [username]" and all this other stuff, but none of that worked. After I typed a new password and retyped it, it gave me an error message saying something like "Authentication Manipulation Error." There was another question complaining about this, but there weren't any useful answers that worked. Does anybody know of a way for me to retrieve or reset my password? Am I doing something wrong with that method I mentioned?

  • Use your own domain email and tired of SPAM? SPAMfighter FTW

    - by Dave Campbell
    I wouldn't post this if I hadn't tried it... and I paid for it myself, so don't anybody be thinking I'm reviewing something someone sent me! Long ago and far away I got very tired of local ISPs and 2nd phone lines and took the plunge and got hooked up to cable... yeah I know the 2nd phone line concept may be hard for everyone to understand, but that's how it was in 'the old days'. To avoid having to change email addresses all the time, I decided to buy a domain name, get minimal hosting, and use that for all email into the house. That way if I changed providers, all the email addresses wouldn't have to change. Of course, about a dozen domains later, I have LOTS of pop email addresses and even an exchange address to my client's server... times have changed. What also has changed is the fact that we get SPAM... 'back in the day' when I was a beta tester for the first ISP in Phoenix, someone tried sending an ad to all of us, and what he got in return for his trouble was a bunch of core dumps that locked up his email... if you don't know what a core dump is, ask your grandfather. But in today's world, we're all much more civilized than that, and as with many things, the criminals seem to have much more rights than we do, so we get inundated with email offering all sorts of wild schemes that you'd have to be brain-dead to accept, but yet... if people weren't accepting them, they'd stop sending them. I keep hoping that survival of the smartest would weed out the mental midgets that respond and then the jumk email stop, but that hasn't happened yet anymore than finding high-quality hearing aids at the checkout line of Safeway because of all the dimwits playing music too loud inside their car... but that's another whole topic and I digress. So what's the solution for all the spam? And I mean *all*... on that old personal email address, I am now getting over 150 spam messages a day! Yes I know that's why God invented the delete key, but I took it on as a challenge, and it's a matter of principle... why should I switch email addresses, or convert from [email protected] to something else, or have all my email filtered through some service just because some A-Hole somewhere has a site up trying to phish Ma & Pa Kettle (ask your grandfather about that too) out of their retirement money? Well... I got an email from my cousin the other day while I was writing yet another email rule, and there was a banner on the bottom of his email that said he was protected by SPAMfighter. SPAMfighter huh.... so I took a look at their site, and found yet one more of the supposed tools to help us. But... I read that they're a Microsoft Gold Partner... and that doesn't come lightly... so I took a gamble and here's what I found: I installed it, and had to do a couple things: 1) SPAMfighter stuffed the SPAMfighter folder into my client's exchange address... I deleted it, made a new SPAMfighter folder where I wanted it to go, then in the SPAMfighter Clients settings for Outlook, I told it to put all spam there. 2) It didn't seem to be doing anything. There's a ribbon button that you can select "Block", and I did that, wondering if I was 'training' it, but it wasn't picking up duplicates 3) I sent email to support, and wrote a post on the forum (not to self: reply to that post). By the time the folks from the home office responded, it was the next day, and first up, SPAMfighter knocked down everything that came through when Outlook opend... two thumbs up! I disabled my 'garbage collection' rule from Outlook, and told Outlook not to use the junk folder thinking it was interfering. 4) Day 2 seemed to go about like Day 1... but I hung in there. 5) Day 3 is now a whole new day... I had left Outlook open and hadn't looked at the PC since sometime late yesterday afternoon, and when I looked this morning, *every bit* of spam was in the SPAMfighter folder!! I'm a new paying customer After watching SPAMfighter work this morning, I've purchased a 1-year license, and I now can sit and watch as emails come in and disappear from my inbox into the SPAMfighter folder. No more continual tweaking of the rules. I've got SPAMfighter set to 'Very Hard' filtering... personally I'd rather pull the few real emails out of the SPAMfighter folder than pull spam out of the real folders. Yes this is simply another way of using the delete key, but you know what? ... it feels good :) Here's a screenshot of the stats after just about 48 hours of being onboard: Note that all the ones blocked by me were during Day 1 and 2... I've blocked none today, and everything is blocked. Stay in the 'Light!

  • Not able to suspend or hibernate

    - by Tim
    My Ubuntu 10.10 on my laptop Lenovo T400 is not able to suspend or hibernate. Whenever I click Suspend or Hibernate, the moon LED on the bottom of the lid flashes a few seconds, the screen quickly shows something like "some devices fail to suspend, error 5", and then the moon LED goes off and the display still has ambient light illumination. I suppose in suspend or hibernation state, the display should have no illumination, just like when the laptop is turned off, right? If I press any key, the unlock screen dialogue will pop out. I searched a little on the internet, and installed 'acpi-support' according to some advice but it does not help. Any suggestions to solve this problem? Thanks and regards!

  • Null Values And The T-SQL IN Operator

    - by Jesse
    I came across some unexpected behavior while troubleshooting a failing test the other day that took me long enough to figure out that I thought it was worth sharing here. I finally traced the failing test back to a SELECT statement in a stored procedure that was using the IN t-sql operator to exclude a certain set of values. Here’s a very simple example table to illustrate the issue: Customers CustomerId INT, NOT NULL, Primary Key CustomerName nvarchar(100) NOT NULL SalesRegionId INT NULL   The ‘SalesRegionId’ column contains a number representing the sales region that the customer belongs to. This column is nullable because new customers get created all the time but assigning them to sales regions is a process that is handled by a regional manager on a periodic basis. For the purposes of this example, the Customers table currently has the following rows: CustomerId CustomerName SalesRegionId 1 Customer A 1 2 Customer B NULL 3 Customer C 4 4 Customer D 2 5 Customer E 3   How could we write a query against this table for all customers that are NOT in sales regions 2 or 4? You might try something like this: 1: SELECT 2: CustomerId, 3: CustomerName, 4: SalesRegionId 5: FROM Customers 6: WHERE SalesRegionId NOT IN (2,4)   Will this work? In short, no; at least not in the way that you might expect. Here’s what this query will return given the example data we’re working with: CustomerId CustomerName SalesRegionId 1 Customer A 1 5 Customer E 5   I was expecting that this query would also return ‘Customer B’, since that customer has a NULL SalesRegionId. In my mind, having a customer with no sales region should be included in a set of customers that are not in sales regions 2 or 4.When I first started troubleshooting my issue I made note of the fact that this query should probably be re-written without the NOT IN clause, but I didn’t suspect that the NOT IN clause was actually the source of the issue. This particular query was only one minor piece in a much larger process that was being exercised via an automated integration test and I simply made a poor assumption that the NOT IN would work the way that I thought it should. So why doesn’t this work the way that I thought it should? From the MSDN documentation on the t-sql IN operator: If the value of test_expression is equal to any value returned by subquery or is equal to any expression from the comma-separated list, the result value is TRUE; otherwise, the result value is FALSE. Using NOT IN negates the subquery value or expression. The key phrase out of that quote is, “… is equal to any expression from the comma-separated list…”. The NULL SalesRegionId isn’t included in the NOT IN because of how NULL values are handled in equality comparisons. From the MSDN documentation on ANSI_NULLS: The SQL-92 standard requires that an equals (=) or not equal to (<>) comparison against a null value evaluates to FALSE. When SET ANSI_NULLS is ON, a SELECT statement using WHERE column_name = NULL returns zero rows even if there are null values in column_name. A SELECT statement using WHERE column_name <> NULL returns zero rows even if there are nonnull values in column_name. In fact, the MSDN documentation on the IN operator includes the following blurb about using NULL values in IN sub-queries or expressions that are used with the IN operator: Any null values returned by subquery or expression that are compared to test_expression using IN or NOT IN return UNKNOWN. Using null values in together with IN or NOT IN can produce unexpected results. If I were to include a ‘SET ANSI_NULLS OFF’ command right above my SELECT statement I would get ‘Customer B’ returned in the results, but that’s definitely not the right way to deal with this. We could re-write the query to explicitly include the NULL value in the WHERE clause: 1: SELECT 2: CustomerId, 3: CustomerName, 4: SalesRegionId 5: FROM Customers 6: WHERE (SalesRegionId NOT IN (2,4) OR SalesRegionId IS NULL)   This query works and properly includes ‘Customer B’ in the results, but I ultimately opted to re-write the query using a LEFT OUTER JOIN against a table variable containing all of the values that I wanted to exclude because, in my case, there could potentially be several hundred values to be excluded. If we were to apply the same refactoring to our simple sales region example we’d end up with: 1: DECLARE @regionsToIgnore TABLE (IgnoredRegionId INT) 2: INSERT @regionsToIgnore values (2),(4) 3:  4: SELECT 5: c.CustomerId, 6: c.CustomerName, 7: c.SalesRegionId 8: FROM Customers c 9: LEFT OUTER JOIN @regionsToIgnore r ON r.IgnoredRegionId = c.SalesRegionId 10: WHERE r.IgnoredRegionId IS NULL By performing a LEFT OUTER JOIN from Customers to the @regionsToIgnore table variable we can simply exclude any rows where the IgnoredRegionId is null, as those represent customers that DO NOT appear in the ignored regions list. This approach will likely perform better if the number of sales regions to ignore gets very large and it also will correctly include any customers that do not yet have a sales region.

  • Wireless speed drops over time and doesn't get up if not reconnected

    - by Vili Lehto
    I am using Ubuntu 12.10 64bit and I have a Asus PCE-N15 wireless card(in PCI-E slot). The problem is that first when I connect to my WiFi network the speed is just fine, and actually my link speed never drops, it shows a solid 150mb/s+ link speed and good signal. But the download and upload speeds drop dramatically after couple minutes of use and I have to reconnect to fix this. Network is type IEEE 802.11bgn and uses WPA2/AES encryption. I don't have similar problems on the windows side, and the network is working fine on every other device. iwconfig shows this: wlan0 IEEE 802.11bgn ESSID:"WLAN-AP" Mode:Managed Frequency:2.412 GHz Access Point: 00:1E:AB:05:EF:31 Bit Rate=300 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off Link Quality=61/70 Signal level=-49 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:2 Missed beacon:0 So the question is: Is there a way to fix this?

  • Node Serialization in NetBeans Platform 7.0

    - by Geertjan
    Node serialization makes sense when you're not interested in the data (since that should be serialized to a database), but in the state of the application. For example, when the application restarts, you want the last selected node to automatically be selected again. That's not the kind of information you'll want to store in a database, hence node serialization is not about data serialization but about application state serialization. I've written about this topic in October 2008, here and here, but want to show how to do this again, using NetBeans Platform 7.0. Somewhere I remember reading that this can't be done anymore and that's typically the best motivation for me, i.e., to prove that it can be done after all. Anyway, in a standard POJO/Node/BeanTreeView scenario, do the following: Remove the "@ConvertAsProperties" annotation at the top of the class, which you'll find there if you used the Window Component wizard. We're not going to use property-file based serialization, but plain old java.io.Serializable  instead. In the TopComponent, assuming it is named "UserExplorerTopComponent", typically at the end of the file, add the following: @Override public Object writeReplace() { //We want to work with one selected item only //and thanks to BeanTreeView.setSelectionMode, //only one node can be selected anyway: Handle handle = NodeOp.toHandles(em.getSelectedNodes())[0]; return new ResolvableHelper(handle); } public final static class ResolvableHelper implements Serializable { private static final long serialVersionUID = 1L; public Handle selectedHandle; private ResolvableHelper(Handle selectedHandle) { this.selectedHandle = selectedHandle; } public Object readResolve() { WindowManager.getDefault().invokeWhenUIReady(new Runnable() { @Override public void run() { try { //Get the TopComponent: UserExplorerTopComponent tc = (UserExplorerTopComponent) WindowManager.getDefault().findTopComponent("UserExplorerTopComponent"); //Get the display text to search for: String selectedDisplayName = selectedHandle.getNode().getDisplayName(); //Get the root, which is the parent of the node we want: Node root = tc.getExplorerManager().getRootContext(); //Find the node, by passing in the root with the display text: Node selectedNode = NodeOp.findPath(root, new String[]{selectedDisplayName}); //Set the explorer manager's selected node: tc.getExplorerManager().setSelectedNodes(new Node[]{selectedNode}); } catch (PropertyVetoException ex) { Exceptions.printStackTrace(ex); } catch (IOException ex) { Exceptions.printStackTrace(ex); } } }); return null; } } Assuming you have a node named "UserNode" for a type named "User" containing a property named "type", add the bits in bold below to your "UserNode": public class UserNode extends AbstractNode implements Serializable { static final long serialVersionUID = 1L; public UserNode(User key) { super(Children.LEAF); setName(key.getType()); } @Override public Handle getHandle() { return new CustomHandle(this, getName()); } public class CustomHandle implements Node.Handle { static final long serialVersionUID = 1L; private AbstractNode node = null; private final String searchString; public CustomHandle(AbstractNode node, String searchString) { this.node = node; this.searchString = searchString; } @Override public Node getNode() { node.setName(searchString); return node; } } } Run the application and select one of the user nodes. Close the application. Start it up again. The user node is not automatically selected, in fact, the window does not open, and you will see this in the output: Caused: java.io.InvalidClassException: org.serialization.sample.UserNode; no valid constructor Read this article and then you'll understand the need for this class: public class BaseNode extends AbstractNode { public BaseNode() { super(Children.LEAF); } public BaseNode(Children kids) { super(kids); } public BaseNode(Children kids, Lookup lkp) { super(kids, lkp); } } Now, instead of extending AbstractNode in your UserNode, extend BaseNode. Then the first non-serializable superclass of the UserNode has an explicitly declared no-args constructor, Do the same as the above for each node in the hierarchy that needs to be serialized. If you have multiple nodes needing serialization, you can share the "CustomHandle" inner class above between all the other nodes, while all the other nodes will also need to extend BaseNode (or provide their own non-serializable super class that explicitly declares a no-args constructor). Now, when I run the application, I select a node, then I close the application, restart it, and the previously selected node is automatically selected when the application has restarted.
