• Sound in Ubuntu 12.10 on Chromebook

  - by Paul Mennega

  I've got an HP Chromebook 14 that I've rooted and installed Ubuntu via Crouton (upgraded to 12.10) and most things are working nicely. One issue that I am having trouble solving relates to sound. I've got sound output that I can control via the individual app (e.g. Youtube), but when trying to control the volume via the built-in xfce4-mixer, I get the following error: GStreamer was unable to detect any sound devices. Some sound system specific GStreamer packages may be missing. It may also be a permissions problem. Opening a terminal, I can run the alsamixer and control the volume levels. It is reporting back that the card is CRAS. I'd love to be able to do it from XFCE and the built-in mixer. I've tried re-installing the GStreamer packages, but no luck. It seems like I am close but not sure where to go from here. On a maybe unrelated note, plugging headphones into the headphone jack in Ubuntu also does not stop the sound from coming from the speakers and nothing comes through the headphones. Switching back to ChromeOs, everything works as expected, so I think that it's a driver issue.

• Massive amount of subfolders and long subfolders. ¿How can I delete all of them?

  - by Carlos

  Good day. We have a little problem here. We have a share with the backup of all the server's offices, Its a really big share with more than 8.000.000 files. Our users usually give long names to the folders they create, and then make subfolders (long too) and more subfolders... and more suboflders.... We have a new share with more capacity, and with a simpe robocopy bat we copied all the files and folders (some give problems, but we manually copied them) But the problem is deleting them. del command didnt work well when so long paths, neirder rmdir... I'm tried some commanders, but no luck. Can u recommend me any tool that can delete recursively or able to delete 255+ paths? Edited: The SO on background of the share it's NetApp OS. But I can access it from Windows Servers. 2000 and 2003 Thanks.

• How to change or remove all traces of original author name in Excel 2010 document

  - by Adam Ryczkowski

  At our company we need to deploy one Excel Workbook in that way that nobody would see it is made by us by looking at the Office metadata. What fields do we need to look for? I know, that the document has track of original writer and the last save author. But is it all? I guess there might be some hidden properties, that might give our company name. Where to look for such fields? Is there any good editor available, or will explorer's property page give enough power? I use Excel 2010

• Failed to load session gnome-fallback, after messing with metacity

  - by Carlito

  I am using Ubuntu 12.04 with gnome-session-fallback (Gnome Classic in the login menu). I wanted to remove window borders from metacity and stumbled across this post which basically changes window->mwm_decorated from TRUE to FALSE, which should remove the window borders in metacity. I know that it is also possible to change your GTK theme to one without window borders, but I wanted to try this solution. So I downloaded the source from my current metacity version (2.34.1) and changed that row. After compiling (./configure && make) I ran checkinstall which generates a .deb file from the source (had to change the version a bit to match the current one exactly). But after installing and loging out and back in, I couldn't load Gnome Classic. I get the error Failed to load session gnome-fallback. I could reinstall the old metacity which was still saved in /var/cache/apt/archives/, so everything is back where it was before. But I would like to mess around with metacity. Have I installed it correctly or did I forgot something? Are there any log files that I should check for solving this error? Thanks in advance!

• Joomla 1.5 Media Manager sets incorrect file permissions when uploading

  - by Scott Mayfield

  Howdy all, I have a Joomla 1.5 installation running on Windows Server 2008, installed via the Web Platform Installer. When uploading images with the media manager (native uploader, not the flash bulk uploader), the files arrive on the server correctly, but are given incorrect permissions. Specifically, the IIS_IUSRS group is not given access to the file. I might be incorrect about what group/user is SUPPOSED to get access to the files, but so far, I've found that unless I give IIS_IUSRS access to the uploaded files, they won't appear on the site or in the media manager (appear as broken images). Once I give IIS_IUSRS permission to the files, they work fine. So far, all the research I've done has led me to linux specific fixes that involve either changing the umask on the server, or directly modifying the Joomla codebase to add an appropriate chmod command to the upload process, but I really don't want to modify Joomla directly. I have to believe there's a setting here somewhere that will do the job, either on the Joomla or Windows side of the equation. Any thoughts? Scott

• Sharing business logic between server-side and client-side of web application?

  - by thoughtpunch

  Quick question concerning shared code/logic in back and front ends of a web application. I have a web application (Rails + heavy JS) that parses metadata from HTML pages fetched via a user supplied URL (think Pinterest or Instapaper). Currently this processing takes place exclusively on the client-side. The code that fetches the URL and parses the DOM is in a fairly large set of JS scripts in our Rails app. Occasionally want to do this processing on the server-side of the app. For example, what if a user supplied a URL but they have JS disabled or have a non-standard compliant browser, etc. Ideally I'd like to be able to process these URLS in Ruby on the back-end (in asynchronous background jobs perhaps) using the same logic that our JS parsers use WITHOUT porting the JS to Ruby. I've looked at systems that allow you to execute JS scripts in the backend like execjs as well as Ruby-to-Javascript compilers like OpalRB that would hopefully allow "write-once, execute many", but I'm not sure that either is the right decision. Whats the best way to avoid business logic duplication for apps that need to do both client-side and server-side processing of similar data?

• Can't Move Windows to 2nd Monitor without Left Mouse and Cntl Key

  - by John C

  I have 2 very frustrating problems that maybe someone can help me with: I have 2 monitors (different sizes and resolutions) setup with the "Extended" monitor Win7 setup. My problem is this = I can not "move" a window from my Primary Monitor (larger and higher resolution on right side in front of me) to my Secondary 2nd monitor (smaller and lower resolution) with just selecting the title bar with the left mouse button and dragging it to the left. Windows 7 "snaps" it back to the left Primary Monitor when the window is physically in the 2nd window area as I'm holding the left mouse button. I can prevent this problem - by holding down the Cntl Key with the Left Mouse button, but this is extremely annoying to me. Also I typically "lose" focus if I try typing input on the 2nd monitor. Typing is erratic with regard to keystroke accuracy from my keyboard translated into input on the 2nd screen. No problem with typing input on the primary left monitor. I find this extremely annoying in Windows 7 and turning off the "snap" feature via the Control panel does NOT work for me. Win7 stubbornly refuses to move my selected window to my 2nd monitor without me "forcing" Win7 to do this with the Cntrl Key. Please tell me this is not a Win7 feature. Also on my system - Windows Key + Shift, Left arrow Key (pressed together) or the same combo with The Right arrow Key - don't do anything whatsoever. Widows Key with "+" however does maximize current window across both monitors, and I can "restore" it with Windows Key and "-" back to original monitor and size. I have tried various solutions including changing the resolutions of one or both of my monitors and sometimes "temporarily helps" but reverts back to the problem. Also if I swap the logical (not physical) layout so that I tell Win7 the monitors are setup in a reserved situation (Large monitor on the left, and small on the right) - this also sometimes helps for awhile - and is very strange and awkward to work with "backwards". But all of these solutions stop working. The only solution that consistently works for "moving" the screens is to hold the Cntrl Key down as I'm moving window with the left mouse selected on the title bar. Even that however, doesn't prevent the loss of typing focus for me on the 2nd monitor - while at the same time the typing on the 1st monitor is fine. Any help on moving my window screens from one monitor on my 2nd monitor without having to press the Cntrl key while holding down my left mouse button with be appreciated. Also any help on gaining typing "focus" into my 2nd screen with be helpful too. Thanks - John

• Recovering from an incorrectly deployed robots.txt?

  - by Doug T.

  We accidentally deployed a robots.txt from our development site that disallowed all crawling. This has caused traffic to dip dramatically, and google results to report: A description for this result is not available because of this site's robots.txt – learn more. We've since corrected the robots.txt about a 1.5 weeks ago, and you can see our robots.txt here. However, search results still report the same robots.txt message. The same appears to be true for Bing. We've taken the following action: Submitted site to be recrawled through google webmaster tools Submitted a site map to google (basically doing everything possible to say "Hey we're here! and we're crawlable!") Indeed a lot of crawl activity seems to be happening lately, but still no description is crawled. I noticed this question where the problem was specific to a 303 redirect back to a disallowed path. We are 301 redirecting to /blog, but crawling is allowed here. This redirect is due to a site redesign, wordpress paths for posts such as /2012/02/12/yadda yadda have been moved to /blog/2012/02/12. We 301 redirect to wordpress for /blog to keep our google juice. However, the sitemap we submitted might have /blog URLs. I'm not sure how much this matters. We clearly want to preserve google juice for URLs linked to us from before our redesign with the /2012/02/... URLs. So perhaps this has prevented some content from getting recrawled? How can we get all of our content, with links pointed to our site from pre-and-post redesign reporting descriptions? How can we resolve this problem and get our search traffic back to where it used to be?

• loading splash screen takes priority over terminal or windows manager while running elsa

  - by schonjones

  I recently installed e17 and was trying to set up defaults to use elsa and ecomorph over the standard compiz as it constantly crashes since updating to 12.04. If elsa is installed the loading screen hangs and never loads to login, however i can get to a terminal or the e17 login instead of the standard gdm that usually shows up, within a second the screen goes back to the loading screen. I can still type and login as well as run commands in the terminal, but all I see is the loading screen. Switching between terminals i can confirm my commands before it switches back to the loading screen. If i remove elsa the loading screen hangs, but I can get to a terminal login and run lightdm to start my session with no problems. I have multiple DE installed and am unsure which loading screen is coming up. i think it's the KDE screen, grub comes up with a debian background if that helps. I'm not sure if i can switch the loading screen and resolve this issue or if i'm just going to have to scrap using elsa and get lightdm to load on boot again. Elsa would be my preference. I don't have the space to backup my files for a complete reinstall. Please help!

• Windows 8 Unable to perform hibernate

  - by Jones

  Windows 8 Enterprise edition x86. Already enabled hibernate option, to have it on shutdown menu (start menu?) and set to hibernate on lid closing. However it's not hibernating for me. When I'm trying to sleep, it's sleep fine and wake up like a kid. But when I'm demanding hibernate, it disconnects internet, turn off screen and be back to lock screen in one second. Steps I've tried. Complete shutdown Clear hiberfile.sys by disabling and enabling back Resetting my power settings. Causes I suspect: Had dual boot with BackTrack with Windows 8 GUI boot manager. It was fine until I reinstall BackTrack, bootmgr resetted and I'm in Ubuntu boot menu;. Using additional hard disk through USB cable.(But it's not a problem before few days, however) How to make my system to hibernate and wakeup again.

• Is it bad practice for a module to contain more information than it needs?

  - by gekod

  I just wanted to ask for your opinion on a situation that occurs sometimes and which I don't know what would be the most elegant way to solve it. Here it goes: We have module A which reads an entry from a database and sends a request to module B containing ONLY the information from the entry module B would need to accomplish it's job (to keep modularity I just give it the information it needs - module B has nothing to do with the rest of the information from the read DB entry). Now after finishing it's job, module B has to reply to a module C if it succeeded or failed. To do this module B replies with the information it has gotten from module A and some variable meaning success or fail. Now here comes the problem: module C needs to find that entry again BUT the information it has gotten from module B is not enough to uniquely find the exact same entry again. I don't think that module A giving more information to module B which it doesn't need to do it's job but which it could then give back to module C would be a good practice because this would mean giving some module information it doesn't really need. What do you think?

• How to stop OS X from switching input method (keyboard layout) automatically?

  - by adolf garlic

  After using the wireless keyboard that comes with the iMac, I have switched to a MS Ergo Natural 4000 one. Surprisingly I had to install extra software as OS X could not work out which keyboard I had. After which I went into sys prefs and set the main input method to be "British - Microsoft" first and "Swiss German" second (what the wireless keyboard is), on the "input sources" tab: However... OS X keeps resetting my input method back to Swiss German which is driving me bananas. I have the flag thingy top right so I can see when this changes. N.B. I have "input source options" set to "use the same one in all documents" which I am assuming means keep the language the same for anything running. It also flips back on the login page. Does anyone know how to fix this?

• Repeat use of Schema / Rich Snippets Markup i.e LocalBusiness Data

  - by bybe

  I am unable to find official wording and I'm hoping that some Rich Snippets/Schema Guru can give me some insight into proper usage of repeated content when it comes to using markup. I'm building a site that wants to use Schema as the markup type and the owner would like as much usage as possible. The business name, telephone and address will appear on every page now is it valid or even useful to use Rich Snippets on every page where this information is displayed. For example this information appears in the header, and footer of every page of the site and too give you an example of my current markup see below: <body itemscope itemtype="http://schema.org/LocalBusiness"> <header> <a itemprop="url" href="http://www.domain.co.uk/"> <img itemprop="logo" src="image.png" alt="Company Name Logo" /> </a> <span itemprop="telephone">01202 000 000</span> </header> <div> This is where the content will go</div> <footer> <span itemprop="name">Company Name</span> <span itemprop="description"> A small little bit about this company</span> <div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress"> <span itemprop="streetAddress">Address Goes here</span> <span itemprop="addressLocality">Area Here</span>, <span itemprop="addressRegion">Region Here</span> </div> </footer> </body> !-- Local Business Schema Now Closed --> So as you can see above this information will be displayed on every single page.... Is this valid or bad to repeat usage of this information in schema format...

• Tomato vs X-Wrt Wireless Router Firmware - which is better?

  - by wag2639

  A few years ago, I've switched over from DD-WRT to Tomato and I haven't looked back since. Before I did, I poked around with OpenWRT but found it too confusing or annoying to use (and I'm a CS major and setup and configured Linux servers using SSH). I'm probably not going back to DD-WRT because of all the controversy but I was wondering how X-Wrt is nowadays? From the screenshots, it looks a lot more featured packed than Tomato and that definitely has its appeal. Then again, simplicity has its advantages to. Any thoughts?

• Automated Acceptance tests under specific contraints

  - by HH_

  This is a follow up to my previous question, which was a bit general, so I'll be asking for a more precise situation. I want to automate acceptance testing on a web application. Briefly, this application allows the user to create contracts for subscribers with the two constraints: You cannot create more than one contract for a subscriber. Once a contract is created, it cannot be deleted (from the UI) Let's say TestCreate is a test case with tests for the normal creation of a contract. The constraints have introduced complexities to the testing process, mainly dependencies between test cases and test executions. Before we run TestCreate we need to make sure that the application is in a suitable state (the subscriber has no contract) If we run TestCreate twice, the second run will fail since the state of the application will have changed. So we need to revert back to the initial state (i.e. delete the contract), which is impossible to do from the UI. More generally, after each test case we should guarantee that the state is reverted back. And since, in this case, it is impossible to do it from the UI, how do you handle this? Possible solution: I thought about doing a backup of the database in the state that I desire, and after each test case, run a script which deletes the db and restores the backup. However, I find that to be too heavy to do for each single test case. In addition, what if some information are stored in files? or in multiple or unaccessible databases? My question: In this situation, what would an experienced tester do to write automated and maintanable tests. Thank you. More info: I'm trying to integrate tests into a BDD framework, which I find to be a neat solution for test documentation and communication, but it does not solve this particular problem (it even makes it harder)

• Recover files after unsuccesfull partitioning

  - by arsan

  I wanted to install another Linux on my comp, so i tried to resize one of my NTFS partitions with Norton Partition Magic, but it didn't complete successfully and it showed some errors and said that the partition is not resized and that it's the same size like before, but when i rebooted my comp i couldn't open that partition anymore and also i am not able to mount it from my linux. So this is my question: I had very important data on that partition - can i recover it back ? I guess nothing's deleted it's just something messed up so it's not usable, but can i get it back ? Please if there's any possible way of doing it, reply to me, thank you.

• Is DevCon.exe still the best way to restart/power cycle USB ports after resuming from hibernation in

  - by ProfessionalAmateur

  I have a USB broadband card on my Windows 7 laptop. It loathes resuming from hibernation properly. Back in the XP days I would issue a call devcon.exe from the command prompt and restart the selected ports (Saves you having to manually unplug and plug back in your USB devices). Ive been trying this is Windows 7, but the UAC keeps getting in the way. I'll start a command prompt. Issue the devcon command, but UAC asks me if I really want to do this, when I click yes it opens a different command prompt and launches the command. After the command completed this new prompt window closes faster than the speed of light and I cannot see the results. So Im thinking there has to be a better way to do this in the Vista/Win7 world...?

• Mercurial mirror: abort: No such file or directory: http://[...]/00manifest.i

  - by Sridhar Ratnakumar

  I am trying to setup a daily mirror of a mercurial repository - code.python.org in particular - within our local network, and serve that via Apache HTTPD. On the remote host that hosts apache, I did this: $ cd /var/www $ hg clone http://code.python.org/hg/trunk/ On my macbook, I ran: $ hg -v clone http://remote/trunk/ (falling back to static-http) abort: No such file or directory: http://remote/trunk/.hg/store/00manifest.i Google does not show any relevant result for this particular error. I remember back in those days being able to setup Bazaar mirrors by a simple clone. Doesn't Mercurial work like that? How do I setup a mirror that must further act like a clone URL?

• Giving a scanner-printer-combo a zoom function when copying ?

  - by ldigas

  You know how everytime you go to a photocopying shop, photocopiers always have a neat zoom function (it can take whatever you give it, and zoom it in/out, so your copy comes out smaller or larger). I got one of those neat 3-in-one printer machines. It has a copy button on it, but it also has some software that comes with it (Epson SX115 to be exact is the model). Apart from going into some photo manipulation application, is there some way (software) to give it that feature. So, in short, I need something that can scan a page, scale it to let's say, a quarter of its size, and then print it out ? Anyone knows of anything like that ?

• Skynet Big Data Demo Using Hexbug Spider Robot, Raspberry Pi, and Java SE Embedded (Part 3)

  - by hinkmond

  In Part 2, I described what connections you need to make for this demo using a Hexbug Spider Robot, a Raspberry Pi, and Java SE Embedded for programming. Here are some photos of me doing the soldering. Software engineers should not be afraid of a little soldering work. It's all good. See: Skynet Big Data Demo (Part 2) One thing to watch out for when you open the remote is that there may be some glue covering the contact points. Make sure to use an Exacto knife or small screwdriver to scrape away any glue or non-conductive material covering each place where you need to solder. And after you are done with your soldering and you gave the solder enough time to cool, make sure all your connections are marked so that you know which wire goes where. Give each wire a very light tug to make sure it is soldered correctly and is making good contact. There are lots of videos on the Web to help you if this is your first time soldering. Check out Laday Ada's (from adafruit.com) links on how to solder if you need some additional help: http://www.ladyada.net/learn/soldering/thm.html If everything looks good, zip everything back up and meet back here for how to connect these wires to your Raspberry Pi. That will be it for the hardware part of this project. See, that wasn't so bad. Hinkmond

• Is there an open source clone of a game in the Total War Series?

  - by sinekonata

  I loved Shogun:Total War gameplay and then later on spent weeks re-enacting historical wars and battles with Europa Barbarorum. It's a mod for Rome:TW that focuses on historical accuracy in the peoples, units, sounds, visuals, everything from macro mechanics to actual battles (e.g. a lot more missiles). Since that time I kind of turned my back on Windows cause it sucks and use Linux cause Mac sucks even worse. So as I miss that game (Eur. Barb.) and consider it the most realistic RTS to date, I'd like to know if there are any free and open source alternatives to it because ever since I'm under linux, I became addicted to FOSS so I also turned my back on paying (even kickstarters) for closed source, pay to play games. I have found a clone/alternative for everyone of the best games like Minecraft, CSS, Natural Selection, TA/SupCom etc... It's kind of the last one I need. The Spring engine is amazing for example, is there another open source project of the source in current development? Or would Spring itself be enough (it certainly looks capable) to make it? Thanks in advance guys...

• The tale of how the PowerShell CmdLets got installed with Azure SDK 1.4

  - by Enrique Lima

  I installed the Azure SDK 1.4 while rebuilding my laptop and ran the installation for the Windows Azure Service Management PowerShell CmdLets. Kicked off the installation script for the WASM PowerShell CmdLets by locating the path to which WASM PowerShell CmdLets was deployed to. Double clicked the startHere command. It will then open the WASM installation dialog. Click Next. Click Next. Notice the red x next to the Azure SDK 1.3, the problem is I have SDK 1.4 Here is the workaround, I go back to the location of the deployed WASM sources. Go into the setup path, then scripts>dependencies>check. Now, locate the CheckAzureSDK.ps1 file, and right-click, then edit. This is the content in the ps1 file, it check for the specific version of the Azure SDK, in this case, it is looking for version 1.3.11133.0038. We need for it to check for version 1.4.20227.1419 Now, save your ps1 file, go back to the open WASM install dialog, and click rescan. This time it should pass, then click next. A Command prompt window will appear, click any key. This completes the installation, click Close.

• How do you redirect pages from a directory to a subdirectory?

  - by kezzman11

  I had recently moved all the content on my website from being in the www.mysite.com/shop directory to being in the root directory. This means that I needed to redirect any request to visit a page with the /shop directory back to the same page in the root directory eg. www.mysite.com/shop/categories/washroom to www.mysite.com/categories/washroom This needed to happen with all pages in my site that were previously using the /shop directory. I was given a solution on here which was: RedirectMatch (^/shop/)(.*) http://www.mysite.com/$2 and it works perfectly however now I have had to switch back to using our old version of our software which is located at the /shop directory so I need the complete opposite redirect now eg. www.mysite.com/categories/washroom to www.mysite.com/shop/categories/washroom Can anyone help me please?
