• Business not showing up on right hand side of google search

  - by Chris

  The business I work has currently has a verified business Google+ page and in the past this page has shown up as a thumbnail during Google searches. The thumbnail brings up basic information such as our picture and operating hours etc. However, since verifying the business page, the thumbnail overview of our business does not seem to show up anymore. I have tried Google searching our business on several computers and it still just brings up the normal search results. Is there a setting I need to activate in order for the thumbnail to appear? Thanks

• Storing documents in DMS

  - by Shaza

  I need your opinions and suggestions about storing documents in a DMS system. I think the DMS should save its own copies of the documents, not their original path on the disk. So, the DMS should have its own space to write on. But what about the way they're stored? Do they have their own extension different from the original one? What about the algorithm that stores them? What about the algorithm that retrieves them? What do you suggest??

• Is it possible to create a virtual drive and share via USB?

  - by Matthew

  My question is kind of hard to follow, but I'm asking if it's possible to make a virtual flash drive and sync it to another device with a USB to USB cable? To make things more clear, think of a typical flash drive. You connect it to a laptop and it shows up as a removable disk. Is it possible to make a computer a host of a "Virtual Drive" that would be connected to a USB cord on one end, and the other end connecting to another device such as a Xbox 360, or another computer.

• How to organize unit/integration test in BDD

  - by whatf

  So finally after reading a lot, I have understood that the difference between BDD and TDD is between T & B. But coming from basic TDD background, what I used to was, first write unittest for database models write test for views (at this point start with integration test as well, along with unittests) write more integration tests for testing UI stuff. What would be a correct way to approach BDD. Say I have a simple blog application. Given : When a user logs in. He should be shown list of all his posts. But for this, I need a model with a row user, another row blog posts. So how do we go about writing tests? when do we create fixtures? When do we write integration (selenium) tests?

• Sensor based vs. AABB based collision

  - by Hillel

  I'm trying to write a simple collision system, which will probably be primarily used for 2D platformers, and I've been planning out an AABB system for a few weeks now, which will work seamlessly with my grid data structure optimization. I picked AABB because I want a simple system, but I also want it to be perfect. Now, I've been hearing a lot lately about a different method to handle collision, using sensors, which are placed in the important parts of the entity. I understand it's a good way to handle slopes, better than AABB collision. The thing is, I can't find a basic explanation of how it works, let alone a comparison of it and the AABB method. If someone could explain it to me, or point me to a good tutorial, I'd very much appreciate it, and also a comparison of the advantages and disadvantages of the two techniques would be nice.

• Why can't get past the user info screen when installing 10.10?

  - by Faceless

  I have a Dell Inspiron 1318 (07-08?) with an Intel Cored 2 Duo Processor and 3 GB of RAM. I can run Ubuntu 10.10 from the disk, but I've tried to install it three times with no success. As the files are installing, the program asks me to enter my user information. I'm fine through the time zone screen, and fine through the keyboard screen. But when it asks me to set my used name and password, the "next" button stays ghosted out no matter what I enter. Eventually, the installation gets to the point where it says it's waiting for me, but no matter what I do I can't get the "next" button to click. I'm a complete newbie, and I've been stuck at the same spot three times. If anyone has any idea what's going wrong, I'd love to hear about it.

• How to balance this Pokémon simulator metagame by feedback?

  - by Dokkat

  This is a Pokémon simulator where you build a team of 6 pokémon and battle with someone. Unfortunately, some Pokémon are stronger than others and only a few of the hundredth species are practical. I'm trying to create a metagame where all of them are competitive. For this, I am tagging a Pokémon with a parameter (level) that changes it's strength and scales up/down depending on the it's performance. That is, if the system detects Mewtwo is overperforming, it should decrease it's level tag until Mewtwo is balanced. The question is: how can I identify if a Pokémon is causing an unbalance? The data I have is the historic of the battles (player 1, player 2, pokémon list, winner). The most basic solution I can think of is victory/loss counting.

• Windows 7/Ubuntu 12 dual boot deleted for Windows 8 installation. How to make grub rescue go away?

  - by dimious

  I had a Windows 7/Ubuntu 12 dual boot and I decided to clean install Windows 8 over them. The problem is that after I deleted all partitions and installed windows I was getting an "Operation system not found", however after an "enter" the system will normally boot into Windows 8. I realized that Windows did their trick and put the system (not partition anymore?!?) "tag" (Disk Management) on my media hard drive. After trying to fix the boot/mbr to be able to boot from my main drive the "Operation system not found" changed to the "grub rescue" prompt. I know that I cannot use that because I have killed the grub files. Windows can still boot as long as I choose to boot from the media drive. The question is, is there any way to move the "system", whatever it is now, to the main drive and have the PC boot from there, while making grub disappear? And if that is possible after that, can I just make the Media drive inactive or I will have to somehow remove the "system" tag?

• Looking for a non-cryptographic hash function that returns a single character

  - by makerofthings7

  Suppose I have a dictionary of ASCII words stored in uppercase. I also want to save those words into separate files so that the total word count of each file is approximately the same. By simply looking at the word I need to know which file it should be in (if it's there at all). Duplicate words should go into the same file and overwrite the last one. My first attempt at solving this problem is to use .NET's object.GetHashCode() function and .Trim() to get one of the "random" characters that pop up. I asked a similar question here If I only use one character of object.GetHashCode() I would get a hash code character of A..Z or 0..9. However saving the result of GetHashCode to disk is a no-no so I need a substitute. Question: What algorithm (or subset of an algorithm) is appropriate for pigeonholing strings into a single character or range of characters (Like hex 0..F offers 16 chars)? Real world usage: I'll use this answer to modify the Partition key used in Azure Table storage as described here

• HTML5-Canvas: worth using ImpactJS or other framework?

  - by John

  I've been making an HTML5 game without any type of external framework. I haven't found a reason to use one so far. However, there is one thing I'm wondering about. On my Galaxy Nexus, I get about ~40fps. While that would usually be a decent framerate, my game is a rather fast paced game with a gamepad. Because of this, it feels very unsatisfying to play when not capped at 60fps. Are there frameworks out there that can improve performance without toning down on graphics? Or is there something I could do myself without necessarily having to use a framework? I've looked over the basic things such as sticking to integer coordinates, but I didn't see an increase in performance whatsoever? I did some testing with jsperf and results were virtually identical. Does this depend more on the browser?

• Ubuntu 12.04 not Locking Encrypted Hard Drive on Log Out

  - by J.L.

  I'm running Ubuntu 12.04 with Gnome 3.4. I have two external hard drives. I encrypted both using Ubuntu's Disk Utility. When I use Nautilus to mount them, I'm asked for my decryption password. Regardless of whether I then click "Forget password immediately" or "Remember password until you logout", though, I find that Ubuntu does not lock the drives when I log out. Rather, when I log back in, they're still mounted. (To be clear, restarting the computer does unmount them so that they require the password on the next log in.) I'm concerned that these drives are remaining unprotected when I log out without restarting my computer. I would be grateful for help understanding whether this is a bug. Thank you!

• Why is web app development path in Java this much confusing? [closed]

  - by Farshid

  I'm currently a .net web developer and I really like to switch to Java. I've used JSP about 7 years ago to develop and deploy a small web application on a JRUN app server. But after 7 years that I like to return back to Java, I can't find the clue. There are many web development frameworks that exist in Java world and each of them has fans that recommand it. There are extensions that sit above jvm for web development (like jRuby i think). I am confused and I do not know where to start the path of learning java web development. I do not want to focus on custom tailor-made approaches and want to remain on the basic path of developing with standard tools and methods and deploy them into standard app servers. (For example some says do not use EJBs, some says focus on MVC facilities like JSF. I'm confused and I do not know the path that i should go on)

• Activate swap by default

  - by San

  I installed Ubuntu 11.04 Natty and I set a partition for swap about 900 MB. Afterthat, I installed Kubuntu 12.10 Quantal, repartitioned my hard disk so I had 2048 MB swap (replaced 900 MB swap partition). I ran Kubuntu, and it's ok. But after I ran Ubuntu 11.04 Natty, It didn't use that swap. But I can activate it with Gparted. Some additional information. When I installed Kubuntu Quantal. I make 256 MB partition (ext4 mount point in /boot) which replaced previous 256 MB partition (ext4 mount point in /boot) that I created when I installed Natty. Something wrong with my configuration?.

• Garbled display after Ubuntu upgrade to 2.6.32-2* kernel

  - by Matthias

  I was running Ubuntu 9 (Karmic Koala) with no problems. I recently upgraded to Ubuntu 10 (Lucid Lynx) and cannot use it normally. After I log in, the screen scrambles (a purple/green mess)--impossible to see anything, although I can get out by marking the spot on the screen to click for a restart, so Linux is working behind the scenes. If I start in recovery mode with basic graphics, I have no problems at all (other than limited functionality). If I start the old 2.6.31-22 kernel, I see a bunch of "unmountable" errors in the startup script, but I can use Linux normally with no apparent problems. I'm running an IBM ThinkPad A30 with ATI Mobility graphics. Just to reiterate, the screen looks normal until I log in, at which point it goes bonkers. What do I need to change in order to fix this?

• How To Get a Better Wireless Signal and Reduce Wireless Network Interference

  - by Chris Hoffman

  Like all sufficiently advanced technologies, Wi-Fi can feel like magic. But Wi-Fi isn’t magic – it’s radio waves. A variety of things can interfere with these radio waves, making your wireless connection weaker and more unreliable. The main keys to improving your wireless network’s signal are positioning your router properly — taking obstructions into account — and reducing interference from other wireless networks and household appliances.

• Is it possible for a web-server to send more files than requested for, and have the browser accept them?

  - by Osiris

  I've created a basic web server for a school project, and it serves static content without a problem. I thought of having the server parse all htm/html files for links to .js/.css/image files, and send these files to the client without these files being requested by the client later. eg. The browser requests: index.htm The server responds with intex.htm and image.jpg I modified the server to send two distinct http responses for a "GET /index.html HTTP1.1" (one for the html page and one for the image), but the browser ended up requesting the image when it was good and ready. Is there any way to bypass this? (use a multipart response, perhaps) Will these files be accepted by most browsers, or will they be rejected for security reasons?

• Bit copy of encrypted home and other partitions

  - by Mka

  My laptop is overheating so I need to save all my files before I format the hard drive. I learned how to copy dev/sdX using dd command. However, I am not sure what to copy. Picture from GParted here: http://is.muni.cz/www/256590/fig.png should I copy sda5 and sda6 only? Or sda2 and sda1? I do not need to use these data on another disk, I just want to be able to access them - therefore I want to put them on external hard drive. And last question - how I will then mount my encrypted home? Will it work? Thanks a lot!

• Recovering a deleted partition

  - by Kishore

  I had a dual boot PC running Ubuntu 12.04 and Windows 7. About a month back, I deleted the Ubuntu partition via the disk management utility (I do not remember whether or not I formatted the partition after performing this action). I ran into some grub issues and used lilo to solve the issue. I followed the simple instructions described in this blog post. I now realize that there were some files in the Ubuntu installation that I need. Of course, I backed up the data, but not this folder apparently. Is there any way to get the data back? I tried following the process suggested on another post on askubuntu (suggesting the use of TestDisk), but was not able to even install TestDisk. The live USB I use is running Ubuntu 12.04 and it does not have a synaptic package manager. Installing from the terminal does not work because even after I type: sudo apt-get update sudo apt-get upgrade the command: sudo apt-get install testdisk fails to work.

• How to fix "error: unknown file system" on all available partitions

  - by Jonathan

  I've had a running problem with removing Linux from my Windows 7 laptop. Initially, it was installed as a dual-boot, and worked well. To remove, I deleted the partitions on my laptop. This removed grub, and I was left with needing to enter: set root=... set prefix=... insmod normal normal each restart. I didn't restore the Windows boot-loader and have since re-partitioned my drive. Now, upon reaching the command prompt screen, an ls query showshd0, with three partitions, but none of them have a recognizable boot-loader as each returns with error: unknown file system. Booting from a Windows 7 rescue disk doesn't seem to work, as it sends me to the same command prompt terminal. All I'm looking to do is restore the boot-loader, either grub or Windows 7. Any help would be appreciated. Thanks in advance.
