• How to remove geoclue-master?

  - by dunderhead

  Looking in System Monitor I saw a process called geoclue-master. As far as I can tell, this reports my precise location to applications and the internet. This computer is sitting in the same office all the time so I have no need whatsoever for such a thing, and would rather have the memory and processor cycles that this unnecessary service uses up - however small - free for things that I do need and want. I could not find instructions for disabling and removing this service so I renamed the file, but then the calendar disappeared from the notification area. Is there a way to remove this service but leave the calendar? I'm using 11.10.

• A good language for c# dev to expand his mind [closed]

  - by Jan Kratochvil

  I have some free time on my hands and I was thinking about learning a new language. I do not plan to use it in my day-to-day job, but I rather want to expand my way of thinking to get a better sense where the dev world is heading from a language perspective and to don't get stuck in my way when programming by rather try new approaches. I was thinking either a functional language, like Haskell or F# (which is a bit more 'pragmatic from a .NET dev standpoint) or something dynamic (like Python, that in my oppinion has nicer syntax than Ruby). What can you recommend that is enjoyable, at least a bit practical, but most of all, new (from a c# dev perspective). I appreciate any answers.

• Is it practical to have perfect validation score on HTML?

  - by Truth

  I was in a heated discussion the other day, about whether or not it's practical to have a perfect validation score on any HTML document. By practical I mean: Does not take a ridiculous amount of time compared to it's almost-perfect counterpart. Can be made to look good on older browsers and to be usable on very old browsers. Justifies the effort it may take to do so (does it come with some kind of reward on SEO/Usability/Accessibility that cannot be achieved in a simpler way with almost-perfect validation) So basically, is perfect validation score practical on any HTML document?

• Rotate to a set degree then stop Unity

  - by N0xus

  I'm trying to make an object rotate up on the Y axis 90 degrees, then stop. I've got the rotating up bit working fine, it's getting it to stop once it hits 90. Some of the things I've tried include the following: float i = rotateSpeed * Time.deltaTime; while ( x != 90 ) { transform.Rotate( i, 0, 0); } int x = 0; x++; if( x == 90 ) { transform.Rotate( 0, 0, 0 ); } For some reason I can't get this simple thing to work. What am I missing / not doing?

• What measures can be taken to make sure Google is aware of the existence of a newly created page?

  - by knorv

  Consider a website with a large number of pages. New pages are published regularly. When publishing a new page the website operator wants to get the newly created paged indexed in Google as soon as possible. The website operator wants to minimize the time spent between publication and indexing. Consider the site http://www.example.com/ with hundreds of thousands of pages. The page page http://www.example.com/something/important-page.html is created at say 12:00. I want to get important-page.html indexed as soon as possible after 12:00. Ideally within seconds or minutes. What options are available to try to get Google to index a specific newly created page as soon as possible?

• Using VBA to model data in Autodesk Inventor?

  - by user108478

  I have a close friend who is using a specific device that records the dimensions of an object as it is eroded and outputs the dimensional data to an excel sheet. The object is spherical in nature but is eroded from the top and bottom, so the shape is constantly changing and a single formula for surface area and volume would not work. This is where Inventor comes in. My friend can plug the dimensional data to Inventor and it immediately returns the surface area and volume. The erosion process takes several minutes to complete and records data at very short intervals, so it would be very arduous to plug in the data thousand of time. Since Inventor supports macros and VBA, is there a way to plug the data into Inventor and output it into another spreadsheet? Any suggestions would be appreciated.

• Virtualbox, How do I change guest (precise) resolution to 16:9 (1920x1080) instead of default 4:3?

  - by CHolmstedt

  There are many questions about resolution issues on askubuntu but no question/solution seems to solve my issue. I've a 12.04/precise host system and installed Ubuntu 12.04/precise as guest system as well. After installation I had the option of selecting 1024x768 (4:3) and 800x600 (4:3) as resolution in display settings. After installing guest additions the options 1280x960 (4:3) and 1440x1050 (4:3) was added to the list. Now 4 in total all having the 4:3 ratio. I then activated full screen mode (host+f) and got the guest running in native 1920x1200 (16:10) for my screen. After deactivating full screen two more options had been added to the resolutions dropdown list, 1920x1200 (16:10) and 1600x1200 (4:3). I want to run the guest in 1920x1080 (16:9) so I can easily record screencasts in "full-hd". Last time I had this problem the solution was to run "VBoxManage controlvm nameofyourVM setvideomodehint width height colordepth" command from the host but now I want to know if there is any easier way to solve this?

• Ubuntu 12.04 wallpaper problem when using two monitors

  - by jiomsa

  I am using two monitors, the main resolution is 1920x1080 and the secondary is 1440x900. Everything seems to work fine (with default drivers, fglrx crashes bad), besides windows opening in the wrong monitor (even when the main is set correctly), but now what I am trying to fix is the wallpaper problem, here's an image to explain it easier: http://i.imgur.com/msLRR.jpg It also happens with gradients. The secondary monitor is physically aligned like in the image, lower than the other, the wallpaper on the main screen seems to keep the size of the lower resolution, and then it start at the correct resolution the last part at right. Any way to fix this? I am using Ubuntu 12.04 with Gnome-Shell 3.4.1, the vga is a Radeon HD 6950 UPDATE I went to gnome-tweak-tool and disabled "Have file manager handle the desktop", now it looks ok on both monitors, but I can't have icons on my desktop, so I am still interested in solving it. UPDATE2 Disabling "Have file manager handle the desktop", in gnome-tweak-tool and then re-enabling it seems to work, but has to be done every time you turn on the PC.

• Shut down Netbook by closing lid - ubunti 13.10

  - by The Liquidator

  My wife has an Acer Aspire One (with the SSD Card and an SD expansion card). It has never been able to hibernate or suspend, always creating errors and occasionally trashing the data on the SD card, which is the home partition so it's unfortunate. To get around the problem I have set all exit methods to produce shutdown - she tends to simply shut the lid. I'm aware the default behaviour has for some time been to suspend, but I've got round that using the gnome tweak tool. However, I've just installed 13.10 and whilst I have installed the gnome tweak tool and set it to shut down the system appears to be ignoring/bypassing the setting, electing to suspend when the lid is shut. Can anyone tell me how to fix it please? I'm quite happy to get my hands dirty with the command line.

• What to do when blocked

  - by darkcminor

  I began to code different for 3 different projects, and it is alright, I have done it for 5 months, some php, some c, some matlab, but for some reason I got stucked... Usually when I pass through this I leave a while or go to sleep (and while sleeping I'm thinking on a solution to the problem I´m currently facing, the most important or urgent), and usually when I return (If I slept well) I have the solution and code comes easily, I don not know what you think, but I have like 10 consecutive days! I can't get out of the hole, I only see how time is going... What do you do when you lose the inspiration (I know leave it a while works), I mean, when all seems like it is not working, no matter what you do. Some friends say Go get some air, do sports, well I have tried... I know lot of you have passed this stage but How...

• Ubuntu install doesn't run on 32Gb Nexus7 with 3g?

  - by raj

  I tried installing Ubuntu on my recently purchased (for this purpose!) Nexus 7 32Gb, with the Cellular option. When I rebooted with Ubuntu, it didn't come up. I know, I need to post the errors I received. I was in a hurry to get back to something usable for the holiday (on the road, Thanksgiving, etc.), so I just reinstalled Android for now. When I have time, I'll post more of the errors. All I remember right now is that it dropped into busybox and I didn't have a keyboard or any way to attach one. (I used the 32Gb Ubuntu, by the way.) Have others seen this?

• Coherence on Exalogic: 6x Speeds on Half the Hardware is Possible

  - by jeckels

  Recently, Oracle Coherence released its 12c version, focused on scalability and real-time data delivery. As part of the launch, we showcased Coherence's tight coupling with Exalogic Elastic Cloud. By leveraging the Inifiniband Fabric in Exalogic, Coherence can now operate at up to 6x the speed on as little as half the hardware on an Exalogic box. This breakthrough is helping customers save money on their hardware costs while improving performance of their data grid. Here's a free resource available for you to explore this technology relationship further.For even more information on Coherence, attend our upcoming free virtual developer day on November 5th to see how developers can leverage Coherence in their everyday tasks.

• Alternative Web model

  - by Above The Gods

  One of the problems web apps have against native apps, especially on the mobile front, is the constant need to re-download each web page on request. Ultimately, this leads to slower performance. Why if web apps only download new pages if they're actually needed, not because they're simply requested. For example: perhaps the server can store a web page version in a cookie. Every slight change to the page on the server-side changes the version number. Now instead of the browser requesting a new page each time, why not just check the version number and have the server send the page if they're different? If the page similar, the user can just use a cached page. I'm sure browsers doesn't necessarily have to change to accommodate changes to this, correct?

• How do I add pcie_aspm=force to my boot options?

  - by nargo7

  I just upgraded to 11.10 from 11.04 on my laptop (I don't have Windows) by downloading from the Ubuntu website. The laptop battery is in bad condition, but I was using it with the 11.04 plugged to AC all the time, and everything was fine. After installing 11.10, the laptop seems to not notice that it is connected to AC, so it shuts down a few minutes after starting. I read that I have to type pcie_aspm=force in the boot command, so I tried accessing it by pressing the "F6" key while booting, and then the other F keys, but nothing happened. I also found that I can write that instruction in the terminal window, but I don't know in which file or location. I would appreciate some help, but I am not a computer engineer, so please write the instructions in plain English.

• gnome-power-manager is running while trying to log in. How to get rid of it?

  - by koushik

  After booting into the ubuntu login screen and clicking on my user name and entering the password, I get a dialog stating that gnome-power-manager is still running. The dialog presents 2 buttons, 1 to Cancel and other to Logout Anyway. This issue happens about 50% of the time and I don't remember doing anything related to power management recently. Also, even if I don't choose any option in the dialog it goes away after about 30s. This is happening on a desktop machine as well as a laptop. On the laptop I have configured power management for myself (not for gdm) whereas in desktop I have not configured power management for any user. This is only an annoyance but still I would like to fix it, especially on my desktop where I am interested in getting it auto-login ASAP into my userid. Any ideas why this could be happenning?

• How to CURL and avoid timeout death (Twitter Down) [migrated]

  - by David

  Twitter is down right now, and one of my site's home pages relies on getting data from Twitter (relies is the problem - it should be more of an accessory feature, as it just shows follow count from its feed). Here's the code in question: function socials_Twitter_GetFollowerCount($username) { $method = function () use ($username) { return file_get_contents('https://api.twitter.com/1/users/show.json?screen_name='.$username.'&include_entities=true'); }; $json = cache('bmdtwitter', 3600, $method, false); $json = json_decode($json, true); return intval($json['followers_count']); } What is a good way to make it so if Twitter is down (or not responsive for some reasonable amount of time), our site doesn't appear to be down (I think the timeout maybe defaulting to 30-60 seconds or more).

• Does saving my progress on a U1-synced file/folder put unneccesary strain on the servers?

  - by Chauncellor

  I love Ubuntu One and I use it all the time. I have my documents and music composition folders set to sync. It's been a real boon. However, sometimes I feel that constantly saving my progress forces the file to sync dozens and dozens of times to the servers. It seems wasteful to me so I've been disconnecting U1 until I'm finished working on a project. Is this an unnecessary action that I am taking? I know it's using Amazon's storage but I'm still paranoid that I'm costing Canonical money when I constantly save my progress.

• Vocabulary: Should I call this apply or map?

  - by Carlos Vergara

  So, I'm tasked with organizing the code and building a library with all the common code among our products. One thing that seems to happen all the time and I wanted to abstract is posted below in pseudocode, and I don't know how to call it (different products have different domain specific implementations and names for it) list function idk_what_to_name_it ( list list_of_callbacks, value common_parameter ): list list_of_results = new list for_each(callback in list_of_callbacks) list_of_results.push(callback(common_parameter)) end for_each return list_of_results end function Would you call this specific construct a list ListOfCallbacks.Map( value value_to_map) method or would it better be value Value.apply(list list_of_callbacks) I'm really curious about this kind of thing. Is there a standard guide for this stuff?

• How do I consolidate the differences between iOS and Android update loops?

  - by kkan

  I'm currently working on moving some Android-ndk code to the iPhone. From looking at some samples it seems that the main loop is handled for you and all you've got to do is override the render method on the view to handle the rendering. Then add a selector to handle the update methods. The render method itself looks like it's attached to the windows refresh. But in android I've got my own game loop that controls the rendering and updates using C++ time.h. Is it possible to implement the same here bypassing Apple's loop? I'd really like the keep the structures of the code similar.

  My server has 2 IP addresses via two networks. Due to some restrictions,my client will be able to access only one of the network at a time. Hence, I want a way to transfer a live ssh session with all the open applications seamlessly from one network to another. The physical devices (client and the server) are the same. What changes is the network through which it connects. can this be done? Thanks!
