• Double launchers and mouse captured between screens in Twinview configuration

  - by Numpty

  Just upgraded to 12.04 and noticed an extremely annoying issue. While using twinview, there now appears to be a launcher on each screen. Moving the mouse between monitors and over the launcher "captures" the mouse for half a second or so, creating the perception of lag. According to some bug reports I've read it appears that a launcher on every screen is a new "feature". Is there any way I can get rid of the 2nd launcher? It's driving my crazy.

• Futures/Monads vs Events

  - by c69

  So, the question is quite simple: in an application framework, when performance impact can be ignored (10-20 events per second at max), what is more maintainable and flexible to use as a preferred medium for communication between modules - Events or Futures/Promices/Monads ? Its often being said, that Events (pub/sub, mediator) allow loose-coupling and thus - more maintainable app... My experience deny this: once you have more that 20+ events - debugging becomes hard, and so is refactoring - because it is very hard to see: who, when and why uses what. Promices (i'm coding in javascript) are much uglier and dumber, than Events. But: you can clearly see connections between function calls, so application logic becomes more straight-forward. What i'm afraid. though, is that Promices will bring more hard-coupling with them... p.s: the answer does not have to be based on JS, experience from other functional languages is much welcome.

• How to loop through a javascript object and check each key exists in a separate multidimensional object

  - by Paul Atkins

  I have 2 javascript objects and I am trying to loop through one object and check whether the key exists in a second multidimensional object going one level deeper each time. Here are the two objects var check = {'scope':'instance', 'item':'body', 'property': 'background'}; var values = {'instance': {'body' : {'background': '000000'}}}; b.map(check, function(key){ console.log(values[key]); }); How am I able to check 1 level deeper in the values object each time? What I am trying to do is check the values object as follows: 1st values['instance'] 2nd values['instance']['body'] 3rd values['instance']['body']['background'] Thanks

• Moving OVD from Test to Production

  - by mark.wilcox

  Customer asked support "How to move a test OVD server to production". There is a couple of ways to do this. One way is to clone the environment: http://download.oracle.com/docs/cd/E15523_01/core.1111/e10105/testprod.htm#CH... Another way - which is particularly useful if you want to push configuration from a parent OVD server to children in a cluster: http://download.oracle.com/docs/cd/E14571_01/oid.1111/e10046/basic_server_set... Note if you use the second option and you have any data in a Local Store Adapter - you may also need to use the oidcmprec tool to synchronize that data: http://download.oracle.com/docs/cd/E14571_01/oid.1111/e10029/replic_mng_mon.h...

• When designing a job queue, what should determine the scope of a job?

  - by Stuart Pegg

  We've got a job queue system that'll cheerfully process any kind of job given to it. We intend to use it to process jobs that each contain 2 tasks: Job (Pass information from one server to another) Fetch task (get the data, slowly) Send task (send the data, comparatively quickly) The difficulty we're having is that we don't know whether to break the tasks into separate jobs, or process the job in one go. Are there any best practices or useful references on this subject? Is there some obvious benefit to a method that we're missing? So far we can see these benefits for each method: Split Job lease length reflects job length: Rather than total of two Finer granularity on recovery: If we lose outgoing connectivity we can tell them all to retry The starting state of the second task is saved to job history: Helps with debugging (although similar logging could be added in single task method) Single Single job to be scheduled: Less processing overhead Data not stale on recovery: If the outgoing downtime is quite long, the pending Send jobs could be outdated

• Utility Queries–Database Files, (and Filegroups)

  - by drsql

  It has been a while since I last posted a utility query, and today, to avoid other work I am supposed to be doing, I decided to go ahead and work on another post.  Today, I went ahead and worked on a server configuration type query. One query I find I use pretty often is the following one that lists the files in the database. In this blog I will include 3 queries.  The first will deal with files and databases, and the second runs in a database to see the files and their filegroups (If there...(read more)

• Battery charging is flickering [closed]

  - by Michael

  A few days ago my notebook started to bug around with charging the battery. When the battery is not absent notebook runs smoothly. Until I plug in the battery. Then it starts to charge but immediately stops and restarts charging and stops and so on. If the notebook is not running battery seems to charge well (LED is not blinking). And LED is not blinking intermittently. Seems to be arbitrary. Does it have something to do with that? This happens every second. [13354.078696] keyboard: can't emulate rawmode for keycode 240

• How to give parallax backgrounds more depth

  - by user28015

  I have 3 tiled images of some sort of galaxy/space in the background of a 2D Game: The first one has an alpha of 100%, the second an alpha of 80% and the last one has an alpha of 60%. I scroll the the one in the background slower than the other ones of course. classic parallax. In the foreground I have some particles flying towards the player to simulate some dust / stars flying by. (I know that stars don't fly by, but I think we all have seen this in a lot of games). But I can't quite achieve the depth effect I am looking for. I want it to look "deeper". I did read something about using blending modes for the backgrounds, but that would require to render them as objects right? So the question is: What is a good technique to do a scrolling parallax background in GameMaker?

• When should one use "out" parameters?

  - by qegal

  In Objective-C, there are several methods like initWithContentsOfFile:encoding:error: where one passes in a reference to an NSError object for the error: parameter. In this example, the value of the NSError object passed in can change based on what goes on at runtime when the method is being called and whether the body of the method was executed in a certain way successfully. In a way I think of this NSError object as sort of like a second return value from the method, and only differs from an object anObject in the statement return anObject; in that when this statement is called, execution leaves the method. So my question is, not only in the context of error handling in Objective-C, but in general, when should one use an "out" parameter in place of returning said value in a return statement?

• SQL Server 2008 R2: StreamInsight changes at RTM: Event Flow Debugger and Management Interface Secur

  - by Greg Low

  In CTP3, I found setting up the StreamInsight Event Flow Debugger fairly easy. For RTM, a number of security changes were made. First config: To be able to connect to the management interface, your user must be added to the Performance Log Users group. After you make this change, you must log off and log back on as the token is only added to your login token when you log on. I forgot this and spent ages trying to work out why I couldn't connect. Second config: You need to reserve the URL that the...(read more)

• How can I teleport seamlessly, without using interpolation?

  - by modchan

  I've been implementing Bukkit plugin for creating toggleable in-game warping areas that will teleport any catched entity to other similar area. I was going to implement concept of non-Euclidean maze using this plugin, but, unfortunately, I've discovered that doing Entity.teleport() causes client to interpolate movement while teleporting, so player slides towards target like Enderman and receives screen updates, so for a split second all underground stuff is visible. While for "just teleport me where I want" usage this is just fine, it ruins whole idea of seamless teleporting, as player can clearly see when transfer happened even without need to look at debug screen. Is there possibility to somehow disable interpolating while teleporting without modifying client, or maybe prevent client from updating screen while it's being teleported?

• Should concrete classes avoid calling other concrete classes, except for data objects?

  - by Kazark

  In Appendix A to The Art of Unit Testing, Roy Osherove, speaking about ways to write testable code from the start, says, An abstract class shouldn't call concrete classes, and concerete classes shouldn't call concrete classes either, unless they're data objects (objects holding data, with no behavior). (259) The first half of the sentence is simply Dependency Inversion from SOLID. The second half seems rather extreme to me. That means that every time I'm going to write a class that isn't a simple data structure, which is most classes, I should write an interface or abstract class first, right? Is it really worthwhile to go that far in defining abstract classes an interfaces? Can anyone explain why in more detail, or refute it in spite of its benefit for testability?

• What kind of connection this is?

  I happened to use `netstat' program this morning.. And what I couldn't understand its results. The snap-shot of the results window is given below: Screen-shot is at http://s2.postimg.org/3zt058415/image.png ( I can't post images! :/ ) Can somebody explain me the last entry in the results, where I've pointed them with arrows? [1] I don't understand why `canonical' servers are connected with my computer even if I am not currently using anything that I would expect such a connection to exist. [2] Second, I don't see the PID/Program name of the Program which has made this connection. I would at-least expect a PID.

• How can i fit 2 commands in 1 terminal shortcut

  - by Nicky Bailuc

  10 latest updates and drivers and I need to run a game called unreal tournament, but in terminal it requires 2 commands The first one is to mount into the folder: cd /usr/local/games/ut2004/ and then the second one is to open the actual game: sudo aoss ./ut2004 In one shortcut i can only fit 1 command but both don't fit in is there any way i can turn these 2 commands into one? Perhaps turni9ng on the desktop shortcut already mounted into the folder? Any help would be really appreciated because im getting kinda sick of using the terminal to run it every time.

• Using .add() on the same widget more than once

  - by Dillon Gilmore

  I asked this question on Reddit and was directed here. http://www.reddit.com/r/Ubuntu/comments/vhadl/quickly_dynamic_ui/ Unfortunately I am having the same issue and the problems seems that you can only use .add() on a widget once. So here is my code, self.ui.labels = [] for titles in entries: label = Gtk.Label() self.ui.labels.append(label) self.ui.viewport1.add(self.ui.labels[-1]) self.ui.paned1.show_all() Now, for fun I decided "What would happen if I just manually did..." self.ui.viewport1.add(Gtk.Label()) self.ui.viewport1.add(Gtk.Button()) self.ui.viewport1.add(Gtk.Entry()) For my first code snippet I get this error, Gtk-CRITICAL **: gtk_viewport_add: assertion gtk_bin_get_child (bin) == NULL' failed The error happens an unknown amount of times because the list entries can vary in length, but for my second code snippet it happens exactly twice. This means that when I viewport1.add() it works the first time, but all adds after that receive the error above. So my question, is there a way in python to use .add() on the same widget more than once?

• How to suppress "Card not present / present" spam in syslog?

  - by vava

  I'm getting a lot of Dec 27 08:35:49 htpc kernel: [ 1552.153797] pciehp 0000:00:1c.5:pcie04: Card not present on Slot(0-2) Dec 27 08:35:49 htpc kernel: [ 1552.157744] pciehp 0000:00:1c.5:pcie04: Card present on Slot(0-2) messages in my syslog, about 10 every second. That just makes syslog unusable, can I somehow get rid of them? I don't know and don't really care about the reason of those messages being there, partly because my motherboard doesn't have pcie slots on it and partly because everything I care about works perfectly. That might be a WiFi chip I disabled in bios but hey, I don't want wifi to be powered on, I'm not using it. So can I just suppress those messages?

• Failure to start grub with Wubi

  - by Marco Ceppi

  My laptop battery ran down and died while using Ubuntu 10.04 with Wubi. Upon recharge (and restart) selecting Ubuntu from the Windows Boot menu brings me to the typical prompt which says (and I paraphrase): Trying hd(0,0) on Disk... After that the screen flickers to white (for a split second) then black. No grub menu comes up (as I would expect) no cursor, no grub sh prompt. Nothing. I've tried switching TTYs to no avail. As there are no logs, I can't trouble shoot anything. I've run a check disk from windows (on the NTFS partition the root.disk is stored) with no luck. What is causing this failure to load grub (and, by association Ubuntu) - How can I restore my setup and get Ubuntu via Wubi working?

• Window controls missing; Cannot maximise or minimize applications

  - by omg_scout

  Ubuntu 12.10 32 bits, fresh installation. How can I make Unity maximize or minimize a window? I see no button,option, anything, do I miss something big? Quick googling did not give me a piece of answer, too: On first screen, I have a terminal window. Only clue about maximizing it I found was pressing F11 which made it fullscreen, hiding left bar as well. I would prefer it to take whole free space instead of whole screen. How can I do that? On second screen, I have an opera browser which takes bigger part of the screen but I can't make it take whole screen. Restarting opera did not work. How do I minimize/maximize apps? Also, in case I would like to see the desktop, only solution I found was closing everything Help guys. I kind of like new GUI, but I can't have simplest tasks done there, I feel like I miss something big there.

• Closing lid does not suspend laptop

  - by fgysin

  I'm on a Lenovo T400 laptop. In the past I had suspend problems on every second version of Ubuntu (at least it feels like it), but in 11.04 it was working perfectly. Now, after the upgrade to 11.10 closing the laptop lid does no longer initialize suspension. When I choose 'Suspend' from the shutdown menu it works perfectly, so this does not seem to be an issue with suspend itself. The options in System Settings>Power are of course set to suspend in case of closing the lid (both for battery and AC poer). Note: I have no idea if this is of any importance, but I'm running the gnome-session-fallback stuff, as I just hate the Unity desgin.

• How to organize my site's file system properly?

  - by Wolfpack'08

  Doing some reading on Stack Overflow, I've found a lot of information suggesting that proper organization of a file system is crucial to a well-written web app. One of the key pieces of evidence is high-frequency references to "separation of concerns" in questions related to keeping programs organized. Now, I've found some information on organizing file systems (Filesystem Hierarchy Standard) from 2004. It raises only two concerns: first, the standard's a bit dated, so I believe it may be possible to do better given the changes in technology over the past 8 years; second, and most important, my application is very small compared to an entire Linux distro. I think that the file system should be organized very differently because of that. Here's what I'm looking at, currently: /scripts, /databases, /www -> /dev, /production -> login, router, admin pages, /sites -> content types, static pages /modules, /includes, /css, /media -> /module-specific-media

• Language Design: Are languages like phyton and coffescript really more comprehendable?

  - by kittensatplay

  the "Verbally Readable !== Quicker Comprehension" arguement on http://ryanflorence.com/2011/case-against-coffeescript/ is really potent and interesting. i and im sure other would be very interested in evidence arguing against this. there's clear evidence for this and i believe it. ppl naturally think in images, not words, so we should be designing languages dissimilar to human language like english, french, whatever. being "readable" is quicker comprehension. most articles on wikipedia are not readable as they are long, boring, dry, sluggish, very very wordy, and because wikipedia documents a ton of info, is not especially helpful when compared to much more helpful sites with more practical, useful, and relevant info. but languages like phyton and coffescript are "verbally readable" in that they are closer to the english language syntax, and programming firstly and mainly in python, im not so sure this is really a good thing. the second interesting argument is that coffeescript is an intermediator so thereby another step between to ends, which may increase chances of bugs. while coffeescript has other practical benefits, this question is focused specifically on evidence showing support for the counter-case of language "readability"

• Recovery from hell - undeleting partition overwritten by Xubuntu 12.10 installer?

  - by DaimyoKirby

  This is turning into a nightmare - following my initial recovery of my two partitions, I went to install Xubuntu 12.10 (again). At this time I had two partitions - one of ~39 GB had Zorin OS 6 installed on it, and another of ~33 GB had nothing installed, just a few files in it that I had manually backed up (moved) there. When I got to the partitioning step, I chose "Replace Zorin OS 6 with Xubuntu 12.10", along with LVM, naturally thinking that the installer wouldn't touch the second partition, since Zorin wasn't installed on it. I was dead wrong. Upon booting my newly installed Xubuntu 12.10, I found in gparted that there were only two partitions - ~255MB, which appears to have the boot stuff in it (it's flagged boot in gparted), and another of ~74 GB. Question: Is there any way to salvage my old files on the non-Zorin ext3 partition? I'm really upset I made such a dumb move (again...), and any and all help is appreciated very, very much!

• Does Ubuntu ever push new versions of GCC into the package repository between releases?

  - by Lex Fridman

  Current version of GCC in Ubuntu 11.04 is 4.5.2. For certain C++0x features, I need GCC version 4.6, but would like to avoid compiling from source. Is there hope that Ubuntu will update GCC in the package repository before the next release in October (11.10). This question asks a similar thing except for an earlier version of Ubuntu and GCC. A second part of the question, if the answer is "no" to the first, then can I hope to see it appear in Ubuntu's unstable repository?

• How to disable integrated webcam and still be able to use an external one

  - by alikasundara

  I am looking for a way to disable the webcam that is integrated into my laptop. The webcam is using uvcvideo module but I do not want to blacklist it since it is also being used by an external webcam I have. Is there any way of disabling the device itself without touching the modules list? This is how the webcams are listed by lsusb. The first one is an integrated one (It is identified by some apps as BisonCam NB Pro), the second one is the external Logitech C525: Bus 002 Device 004: ID 5986:0361 Acer, Inc Bus 003 Device 002: ID 046d:0826 Logitech, Inc. I have already checked BIOS - there is no way of disabling the webcam from there. Besides I would love to learn how to disable the device by ID anyway. Thanks!
