• What happened to my files?

  - by Ivan Broes

  After a successful upgrade from 11.04 to 11.10 a gradual deterioration occurred -- my laptop became unstable with updates -- I corrected the Aspell file, only to have another appear, I sought but I was blocked out. Had an idea, but resolved one that another problem appeared -- going from bad to worse -- I re-installed windows Vista and Ubuntu 11.10 in the original partitions. Window called it Windows Old and I had no problems recovering my files there - Ubuntu decided it is going to make a new Home directory -- . the questions is where did these files go to after re-installation -- are they deleted? If so That's fine duplicates are in Ubuntu 1 by synchronization - I can only download one file at a time!

• Welcome to our Friday tips series!

  - by Chris Kawalek

  Today we're starting a brand new blog series. For your Friday afternoon reading, we'll be posting a technical tip or question and answer on a technical topic. We'll start by introducing ideas on our own, but we'd really like it if you were involved and asked us questions via Twitter! Tag your tweet with #AskOracleVirtualization and we'll consider your question for the blog. Today's tip is on Storage and Oracle Virtual Desktop Infrastructure: Question: I run Oracle Virtual Desktop 3.4.1 on Solaris and use a local ZFS storage pool.  How should I configure my ZFS ARC cache?  Answer by John Renko, Consulting Developer, Oracle: Oracle recommends about 5G of ARC cache per template in use to achieve up to a 90% disk read offload. Set your ARC min=max to reserve the maximum amount of your remaining memory for your running VMs. In /etc/system: set zfs:zfs_arc_min = 5368709120 set zfs:zfs_arc_max = 5368709120 The amount you need to reserve will depend on your template but this has proven to be a great start for a typical windows 7 VM running productivity applications.

• Collision Systems Implementation

  - by hrr4

  Just curious what might be a good way to implement a decent collision system. As a class inherited by a base Entity class? Currently I'm stuck and could just use a couple better ideas than my own. Any help is appreciated! Edit: Sorry, it's 2D Collisioning but honestly, I'm not looking for specific collision methods. I'm looking more about the lines of implementation. Just curious of some of the common methods of how to implement collision systems such as: Should the entire collision system be it's own class? What, if anything, should be inheritable? These are some of my questions. Sorry for the confusion.

• Application lens as default

  - by user24484

  I want to open the Application lens in the Unity Dash as the default lens, since I much more open a programm then searching for a wikipedia article, the weather or anything else the home lens offers. Here How do I show the Applications Lens By Default? and here What are Unity's keyboard and mouse shortcuts? are the same questions, but the suggested answers don't work anymore on Trusty. I know that I can open the application lens with Super + A but I just would like to press Super to open it. An alternative would be to only get online suggestions whe partikular asked for them, but even though I just select the application scope in the filter section I get some useles online results. Btw. I don't want to open the online search results in generall, since I just reactivated them to try it out.

• How to play many sounds at once in OpenAL

  - by Krom Stern

  I'm developing an RTS game and I would like to add sounds to it. My choice has landed on OpenAL. I have plenty of units which from time to time make sounds: fSound.Play(sfx_shoot, location). Sounds often repeat, e.g. when squad of archers shoots arrows, but they are not synced with each other. My questions are: What is the common design pattern to play multiple sounds in OpenAL, when some of them are duplicate? What are the hardware limitations on sounds count and tricks to overcome them?

• pop up html as javascript string instead of hidden div for seo [closed]

  - by user1324762

  Possible Duplicate: How bad is it to use display: none in CSS? I have heard that using display:none or visibility:hidden css properties are not a very good idea for seo purposes. I have about 4 different pop up windows to display and each one has about 20 words inside it. I can create hidden divs. Another option is to store div html elements as javascript string. In this way pop up html elements will be generated from javascript string. This will be still faster than using ajax since the data is static. Is this method absolutely safe for SEO? P.S.: I was just asking about similar question on http://stackoverflow.com/questions/12389075/storing-data-in-javascript-array-for-further-use, but this one is different, it is about static data and about SEO.

• How is Logitech C510 HD Webcam

  - by Ashfame

  I am going to buy Logitech C510 HD webcam and I just checked on other questions here on AskUbuntu that it works out of the box with cheese. Jorge's response also confirm this and I feel confident buying it now. My question is can it be limited in any functionality that I would like to do with it? I would like it to be used with everything - Skype, Gtalk video chat, Facebook, Youtube etc. Also this may sound lame but I need to know whether I could record or do a video call in lesser resolution video (its a 720p one)? Edit: Ported part of this question to another question to make it more specific.

• Is it me, or is it you? Does the sync work?

  - by bisi

  I have been on this for several hours now, trying to get a simple second folder to sync with my (paid) account. I cannot tell you how many times I removed all devices, removed stored passwords, killed all processes of u1, logged out and back in online...and still, the tick in the file browser (Synchronize this folder) is loading and loading and loading. Also, I have logged out, rebooted countless times. And this is after me somehow managing to get the u1 preferences to finally "connect" again. I have also checked the status of your services, and none are close to what I am experiencing. And I have checked the suggested related questions above! So please, just confirm whether it is a problem on my side, or a problem on your side.

• Help me come up with my new job title

  - by Seva Alekseyev

  Hi all, I used to be a technical lead in a group of 3-5 programmers. Tech lead's responsibilities here would include thinking of/designing overall solution architecture, coding, refactoring, being the first to dive into the next big thing, reviewing others' code, sitting on customer meetings and answering endless questions from the rest of the team. Now I'm moving on to a branch-level position (in a branch of ~60 people), which entails pretty much the same, sans maybe the coding/refactoring part. Still kinda a tech lead, but the title "tech lead" is already being used and means something else - a group-level tech lead. Please help me come up with a good job title. I need something for my e-mail signature and, eventually, resume.

• Proper password handling for login

  - by piers

  I have read a lot about PHP login security recently, but many questions on Stack Overflow regarding security are outdated. I understand bcrypt is one of the best ways of hashing passwords today. However, for my site, I believe sha512 will do very well, at least to begin with. (I mean bcrypt is for bigger sites, sites that require high security, right?) I´m also wonder about salting. Is it necessary for every password to have its own unique salt? Should I have one field for the salt and one for the password in my database table? What would be a decent salt today? Should I join the username together with the password and add a random word/letter/special character combination to it? Thanks for your help!

• Putting coworkers as references in CV [closed]

  - by Jaded

  My friend is working in one organisation for some time and wants to change a job. Problem is that motivation is money related (management is refusing to raise salary without any explanation despite 1) they don't have any questions nor problems related to his work 2) they promised raise long ago) and they won't find anyone to replace him. So they not just won't recommend him, but surely will say he is bad specialist and person as he leaves. Don't put that work in CV is not an option, so he thinks the possible solution is to reference his co-workers and teammates. He didn't work for them as employee, but he worked with them, so their (100% positive) feedback looks like fair compensation of what management will say. Is that correct? Looking for interviewers/employers opinion.

• Have you used a Framework/Lib whose LGPL License? if yes, what are the impressions of your customers?

  - by Smarty Twiti

  I am trying to make my first app for sale, I would like to ask some questions for those who have already sold their software: Have you used a Framework/Lib whose LGPL License? if yes, what are the impressions of your customers? for example, if your customers/ competitors from the market reveal technology/secrets that you used in your solution (as LGPL requires that you make a Dynamic Link (.DLL) for your libs and you clearly tell the use of a Lib/Framework). Full story: For my project, I used a framework LGPL/commercial (Dual License) the second one it was too expensive (about 3000 USD) which pushed me to use LGPL however I still concerned. That is why I ask for advise and especially motivations.

• Managing SharePoint permissions via Active Directory?

  - by rgmatthes

  My company has thousands of employees organized thoroughly via Active Directory. I have confidence in the accuracy of the Department and Title information displayed in the user profiles. I'm helping to put up a brand new SharePoint 2007 site, and I contacted IT about managing the site's permissions through AD Groups. The goal is to have the site automatically assign read/write/contribute/whatever permissions based on the information in AD. For example, we could create an AD Group called "Managers" that would contain anyone with the "Manager" title in their AD user profile. I would have SharePoint tap into this AD Group to mass assign permissions if I knew all managers would need a certain level of access (read/write/contribute/whatever). Then if a manager joins the company or leaves it, the group is automatically updated (provided AD gets updated, of course). My IT rep called back and said it couldn't be done. This seems like a pretty straightforward business requirement, and one of the huge benefits of having Active Directory, but maybe I'm mistaken. Could anyone shed some light on this? A) Is it possible to use dynamically-updated AD Groups when assigning permissions via SharePoint? (Does anyone know of a guide I could show my doubtful IT rep?) B) Is there a "best practice" way to go about this? I've read some debate on whether SharePoint Groups or AD Groups are the way to go. My main concern is dynamic updating. C) If this isn't available out of the box, can someone recommend third-party software that will provide the functionality I'm looking for? A big thanks to anyone who can help me out!!

• Sync Local ICS File with Android via Exchange/Outlook

  - by sinDizzy

  At my company we have a 3rd party app which tracks off-hours duty for all of our engineers. The app is not web-enabled and we cannot make any changes to it. It does write a simple text file and I have created an app that translates that to an ICS file. My goal is to have that appear on my calendar on my Android phone. Here is the path I am working on: DutyApp -- TextFile -- ICSFile -- Outlook(exchange) -- Android (via exchange sync) My problems: If I place the ICS file on our FILE server and then in Outlook if I go to the option CalendarOpen CalendarFrom Internet it shows up in Outlook and looks pretty good. After a couple minutes it shows up on my Android phone as well. If I change the original ICS file those changes never display in Outlook and never sync to my Android phone. This seems to be a one shot deal almost like an import. Now if I place the ICS file on our WEB server and then in Outlook if I go to the option CalendarOpen CalendarFrom Internet and use webcal:\ as the address, it shows up in Outlook and also looks pretty good. Any changes I make to the original ICS file display in Outlook. However the entire calendar never shows up in Android. This calendar is a subscription and it seems, although am not sure, that Android doesn't display Exchange subscription calendars. Yes I know it works with Gmail subscription calendars but this is Exchange. So my question is what other options are there? We are behind a firewall so cant link the ICS file to a Gmail account. I can't put the ICS file anywhere else other than our file or web server.

• Soundtest works, but no other sounds and windows starts very slowly

  - by Kristian Kari

  So suddenly all sounds on my computer stopped working expect the sound test works, but when I go to control panel and audio it says there's no audio device. And audio players and audio on website doesn't work either. and Also windows starts very slowly. I'm not sure if this helps but I'll tell what happened before this. I downloaded this program from a little shady website, I hesitated and for a good reason I guess cos the moment I finished downloading it, my antivir detected it as unwanted program and put it on quarantine. I thought everything was fine, but had some problems with program (won't go to details about it cos it's not really related to audio) so rebooted the computer and I was suprised that windows started really really slowly. It took like 5 mins to load the desktop such. After that I noticed the sounds were missing, I immediately deleted the program since I thought it was causing the problem. But it didn't change much. I tried to find the solution with no success and now I'm just scanning again my computer. I'd be thankful if anyone would be able to help me. I might have left a thing or ten things out, so feel free to ask. oh and I'm using windows xp

• Google Drive terminates without error on startup

  - by Iszi

  I've used Google Drive for awhile now, but it won't start up after installing on my latest system re-build. I'm still using the same OS, hardware, and basic software load (antivirus, firewall, etc.) that I have for years during which I had not previously had problems with Drive. OS: Windows 7 Ultimate x64 Google Drive Version: 1.12.5329.1887 Now, whenever I try to run Google Drive, it just spawns two instances of the executable which die shortly after. No error messages are posted to the desktop, and nothing indicating any problem is written to the Event Log. After some research, I've yet to find anyone having the same problem who's found an answer. I did find out how to run Google Drive in diagnostic mode, using the --vv parameter at the command line. After that, I opened up the sync log and got this: 2013-10-31 17:11:24,039 INFO pid=3664 1892:MainThread logging:1600 OS: Windows/6.1.7601-SP1 2013-10-31 17:11:24,039 INFO pid=3664 1892:MainThread logging:1600 Google Drive (build 1.12.5329.1887) 2013-10-31 17:11:24,039 DEBUG pid=3664 1892:MainThread logging:1608 DEBUGGING DUMP is ON. 2013-10-31 17:11:24,051 ERROR pid=3664 1892:MainThread logging:1575 ERROR, UNEXPECTED EXCEPTION 2013-10-31 17:11:24,051 ERROR pid=3664 1892:MainThread logging:1575 [Error 5] Access is denied Traceback (most recent call last): File "<string>", line 232, in Main File "<string>", line 118, in RegisterCustomFileTypes File "P:\p\agents\hpal4.eem\recipes\353983091\base\b\drb\googleclient\apps\webdrive_sync\windows\build\pyi.win32\main\outPYZ1.pyz/windows.registry", line 62, in GetValue WindowsError: [Error 5] Access is denied 2013-10-31 17:11:24,052 INFO pid=3664 1892:MainThread logging:1600 Crash reporting disabled.

• Windows 2008 R2 file share - any way to "lock it down" outside of a 3rd party app?

  - by TheCleaner

  I have a 3rd party app that "makes a call" to write files to a file share on our network using the currently logged in credentials of the Windows domain user. Meaning the 3rd party app doesn't pass the apps credentials but simply issues a behind the scenes copy command to take a source file specified and copy/move it to the destination "repository" on the file share. The basic premise is that it keeps revisions/approvals for Document Control (think svn/git I guess, similar to this question: Lock down Windows folder to only be updatable by SVN). This all works fine...but here's my issue: I need a way to lock down the file share from being accessed/modified outside of using the 3rd party app (meaning prevent explorer/word/excel/etc from getting to that share). I know I can do the following: make the share a hidden share ($) - this definitely helps. Most users would have zero clue on how to get to such a share. Solves probably 95% of my issue. go one step further and set the "Hidden" attribute on the folders in the hidden share - this would go a little further in that even if a user knows the path to the hidden share like \\server\hidden$ they still won't see folders in that share without changing their explorer options to "show hidden files/folder Any other ideas on how I can lock this down? The users still need modify rights to this share/folders since the 3rd party app relies on their Windows permissions to that location when copying the files into it. I can't really use 3rd party tools to password protect the folder/share without causing the 3rd party app functions to fail.

Although, if i login as a guest, it works fine. I have already used startx command, and tried reinstalling the desktop as well but it doesn't work! If I use ctrl+alt+f9, terminal screen vanishes and a black screen appears, and then nothing happens after that. ctrl+alt+f1 takes me to the command prompt. I know similar questions have been asked here, but i could not find a solution for my laptop. Please help!!
