• What's new at Oracle in Gamification?

  - by erikanollwebb

  It's been a crazy few weeks in Apps UX.  We are actively working on some gamification designs in now 4 different application product areas, as well as supporting some teams in other areas of Oracle.  Since that gets to be a pretty diverse group with a lot of resources and ideas, we've started a group in the Oracle Social Network on Gamification at Oracle.  That's limited to internal users at Oracle, but if you are interested in joining,  ping me directly for more information at [email protected]. We're planning another design jam like we did here at Oracle in May and at the Enterprise Gamification Forum in San Diego in September.  This time, we're taking the show to the UK, and hosting it with a group of customers on the Oracle Usability Advisory Board.  It should be a great event!   We're also actively designing some gamified flows which we'll be testing with users at the UKOUG to see what our customers think about some of our gamification ideas. We're looking at more feedback opportunities.  Internally, we surveyed 444 folks within Oracle about gamification and we'll be posting some of our findings on that here soon.  I'll be posting a blog on gamification for our customers at useableapps.oracle.com  in the next few weeks and I'll cross-post to here when it comes out.  So even though it's been quiet on this blog, we are busy and I'm hoping to push out more content in the next few weeks!  Would love to know what's most interesting to the folks reading so if there's something you especially want to see, feel free to comment or email me about it.

• Dynamic VPN tunneling technologies

  - by Adam

  Ok, so I'm asking a more specific question this time. I'm writing a paper about Cisco's DMVPN and one of the tasks I have is to make the analysis of available network solutions which use dynamic VPN tunnels. Because the paper is about DMVPN, I have to compare those solutions to it. I know there are a lot of dynamic tunneling technologies but I'm looking for ones that can be compared to DMVPN. So the question is: are there any technologies which use dynamic VPN tunnels (not necessarily using crypto) that can be compared to DMVPN? What are those technologies?

• How can I shut down all my Virtual Machines when my UPS kicks in?

  - by Tim

  I have a Dell T610 running ESXi4, an APC Smart UPS 1000VA and a local "console" machine running Vista and the vSphere 4 Essentials pack. A dedicated management network is in place between the T610 and the Vista machine. We have 4 VMs: SBS 2003, Server 2003 running Terminal Services, and two XP Machines. Ideally, when the UPS is forced to use battery power [for a set number minutes], I would like to gracefully shutdown all the VMs, then the ESXi, then the console machine. The latter two are not strictly a priority, but the VMs within ESXi are. Google provided lots of deprecated scripts that used to work on ESXi 3.x or similar, however I am unable to find what they were deprecated by. What do I need to be able to do this? I have Powerchute Express as supplied with the UPS, but would be willing to pay for software if required.

• What's static.ak.fbcdn.net that appears on the status bar of my browser everytime Facebook is loading?

  - by Maverick

  I find the message: "waiting for static.ak.fbcdn.net..." on the status bar of my browser everytime I load Facebook and many a times even while loading other websites. I searched on net and found out that static.ak.fbcdn.net stands for static akamai facebook content delivery network. I reckon that static.ak.fbcdn.net is the server URL from where Facebook delivers contents to our browser. Am I right? Can anyone elaborate? Also, why does the above mentioned message appear while loading other websites too?

• software for compression-decompression of pictures

  - by infant programmer

  I need to send hundreds of pictures via email. The size is reaching 100s of MBs .. which is certainly burden on network. WinRar, 7-Zip aren't helping .. Would you like to suggest any software which can carry out compression so that I can reduce the size and send it via email, and decompress it at the other end .. opensource or freeware are more preferred .. paid-versions are appreciated too Edit: I am seeking an alternative software for winrar and 7-zip which is more efficient in compressing .. but still not losing any data ..

• debian hang on startup "starting the winbind daemon: winbind"

  - by Bajingan Keparat

  I took a copy of a VM running a debian, just so that I can play around with it. I spin up the copy, but didn't give it any network connection to avoid conflict with the original one. However, when I turn the VM on, it seems to freeze after this startup message Starting Sambe daemons:nmbd smbd Starting PostgreSQL 8.4 database server: main Starting the Winbind daemon: winbind how do i fix this? I never get to the prompt to login. This vm does have a mount point that connects to a windows share folder.

• Why can't gif images copy at a reasonable speed on this dell laptop with XP?

  - by alt234

  I've got this somewhat old Dell Latitude D810. Strangest thing... If I try to copy anything that has gif files in it the gif files take forever. Like a few minutes per gif regardless of size. Everything else copies fine. I notice this when copying files off our network, copying off multiple external drives, and even when files are copying during an installation process. I'm on Windows XP Pro service pack 3. I've never seen anything like this before. Anyone else?

• What's wrong with my MAC address?

  - by Shaul

  I have a D-Link DSL-2650U router, and exactly one computer on the network. For reasons of port forwarding I want to give my computer a static internal IP address, so that I don't take the chance of losing my NAT settings every time the computer reboots. So here's a screen shot that summarizes the entire problem: WTH is wrong with my MAC address? It's copied and pasted from the command prompt window! I tried editing out the dashes, but it still doesn't work. Am I doing something wrong, or is there a bug in the D-Link firmware?

• How do I set the UNC permissions on a SQL Server 2008 Filestream UNC?

  - by Justin Dearing

  I have a SQL Server 2008 instance. I have configured filestream access properly, and use it from one column on one table in one of my databases. However, I cannot access the UNC share for the filestream data. I have tried browsing to it as well as trying to open specific files and I get errors both ways. I am running SQL Server 2008 enterprise on a Windows 7 workstation running on the domain. I've tried running the sql server service as a local user, then as network admin. The user I am logged in as is a local admin and a sysadmin in SQL server.

• What would be the best way to correlate logs and events on several hosts?

  - by user220746

  I'm trying to build a log correlation system on multiple hosts. SEC seems interesting but I don't know if it will cover my needs. How could I correlate system events, logs, network events, etc. on multiple hosts at the same time, in real time? Examples: If 5 failed logins happened on host A the last minute and if firewall B has denied lots of access on differents ports on A, then we assume there is a potential attack in progress on A. If the Apache service on host A didn't receive any request for the last N minutes and Apache service on host B did, then the load balancing could be faulty.

• Monitoring host and app parameters in real-time

  - by devopsdude42

  I have a bunch of VMs that I need to monitor in real-time. For all nodes I need to watch host parameters like load, network usage and free memory; and for some I need app-specific metrics too, like redis (some vars from the output of INFO command) and nginx (like requests/sec, avg. request time). Ideally I'd also like to track some parameters from the custom apps that run on these node too. These parameters should get tracked as a bunch of line charts on a dashboard. I checked out graphite and it looks suitable (although the UX and aesthetics looks like it needs some love). But setting up and maintaining graphite looks to be a pain, esp. since we don't have a full-time person just for this. Are there any alternatives? Or at least something that is simpler to setup and will scale? Reasonable paid services are also ok.

• Why does VNC eat certain characters?

  - by TK Kocheran

  I often use VNC to connect to my desktop upstairs using a laptop downstairs over my home network. I tunnel the VNC connection via SSH. The problem I keep running into is that I'll attempt to type a ! or a : or even a captial A and it will come across the wire as a 1, ;, or a respectively. Is this something I can fix? It's really REALLY annoying while one is programming to have to pop open character map and find a colon and copy/paste it in each time. Running Ubuntu 10.04 upstairs, Linux Mint 10 downstairs.

• Upgrade to 0.25, files served to uPNP devices cannot play

  - by David Buttrick

  I have a Sony BDP-S390 bluray & network player. I upgraded my Myth server to 0.25. When I browse to the Myth server, and try to play a recording, I get an error message about the file not being payable in the player. Interestingly, the files that i have recorded, and the videos that I have loaded into my Video volume group are .mpg or .mp4. The player shows the filetype that it thinks the file is in it's list, and it claims that these files are AVI files, however none of them are. They are all .mp4 or .mpg files. Thinking that that was just an optical illusion, I went ahead and tried to play a file, but I get an error about the file not being playable. First of all, is there something that I need to do to make the uPNP server know about different filetypes? Is it reporting AVI because it hasn't been told about MPG or MP4? Second, I'd like to help out some more here and collect some logging about the uPNP server in the myth server. I cant seem to find information on how to turn on logging, and there is no mythbackend settings file int /etc/default. Thanks very much.

• There is a commercial tool like Xen + Remus?

  - by SoMoS

  Hello, I have a project where we need a completely redundant system like the one offered by Remus with a Xen virtualization system. I wondered if there is a system like this one built by VMWare or some other company because the project is a very critical one and we do not want to have to wait that a bug is fixed by "the community" and money is not a problem. What Remus does is to build a completely redundant system where you can shutdown one machine and the other continues the work where the other left it maintaining the network connections opened, etc Any hint? Thanks in advance.

• Recommended Tape Library Backup software

  - by D4

  Hi, I recently "inherited" a Tape Library (Powevault 136T / Scalar 100). and I was asking for some advise on the backup software to manage the Library. My goal is to be able to manage backups of all my servers (linux and Windows) and also backup VIP´s laptop computers over the network. I am hoping for a GUI application since I will not be the one managing the process after a couple of months... Any idea is more than welcome... thanks in advance....

• No write access on Windows 2008 workgroup share

  - by Serge - appTranslator

  Hi All, I'm trying to access network shares on my new Windows 2008 server (workgroup) using my server's local admin account. I can read files but not modify them. Permissions (sharing + file system) say: Users = Read only. Admins = Full Control. Even though I connect using my admin account (net use x: \\server\share /user:server\me), I can't write. OTOH, I have another share on the same computer where users have Read AND Write. I can write into that one. What's the problem? Does it have to do with UAC? TIA for your help.

• The Most Ridiculous Computer Cameos of All Time

  - by Jason Fitzpatrick

  For the last half century computers have played all sorts of major and minor roles in movies; check out this collection to see some of the more quirky and out-of-place appearances. Wired magazine rounds up some of the more oddball appearances of computers in film. Like, for example, the scene shown above from Soylent Green: Spoiler alert: Soylent Green is people! But that’s not the only thing we’re gonna spoil. Soylent Green is set in 2022, and at one point, you’ll notice that a government facility is still using a remote calculator that plugs into the CDC 6600, a machine that was state-of-the-art in 1971. Come to think of it, we should scratch this from the list. This is pretty close to completely accurate. Hit up the link below to check out the full gallery, including a really interesting bit about how the U.S. Government’s largest computer project–once decommissioned and sold as surplus–ended up on the sets of dozens of movies and television shows.

• Oh snap! My RPi was upgraded to 512MB! Woo-hoo!

  - by hinkmond

  I ordered a Raspberry Pi Model B (256MB) over 4 months ago on backorder. When it finally came I saw it was upgraded to the new half a gig model! Woot! But, all was not perfect. Gary C. told me the shipped configuration of the new RPi models didn't have the right firmware for 512MB, and I had to upgrade the start.elf in the /boot directory to recognize all of the 512MB RAM. I did a "free" command, and sure enough saw only 240MB. Sadness. But, Gary gave me a copy of his start.elf which worked after some trail and error. For anyone ordering the new RPi Model B w/512MB, here are the steps to get you going with full 512MB RAM: sudo apt-get update --fix-missing sudo apt-get upgrade --fix-missing # NOTE: This step takes at least a couple hours on a # fast network wget https://raw.github.com/raspberrypi/firmware/\ 164b0fe2b3b56081c7510df93bc1440aebe45f7e/boot/\ arm496_start.elf sudo mv /boot/start.elf /boot/orig-start.elf sudo mv arm496_start.elf /boot/start.elf sudo reboot free total used free shared buffers cached Mem: 497768 210596 287172 0 16892 169624 -/+ buffers/cache: 24080 473688 Swap: 102396 0 102396 So of course this means... (drumroll) there is now 498MB available for the Java Embedded heap! java -Xmx400m -version java version "1.7.0_06" Java(TM) SE Embedded Runtime Environment (build 1.7.0_06-b24, headless) Java HotSpot(TM) Embedded Client VM (build 23.2-b09, mixed mode) Yeah, baby!

• Prevent machine in a LAN from receiving a remote shutdown

  - by WebDevHobo

  I'm probably just overreacting, but I recently came across a LAN-scanner that showed me the option "remote shutdown", for all found computers on the scanned network. Now, how exactly does this work? If I send such a message, will the shutdown happen no matter what, or is it required to have the password/user-name of the user of that other computer. Mostly I'm wondering: can this be done to me and how do I prevent it? EDIT: what's more, I had the scanner check for shares. The result being this: Double clicking the links opens them in explorer, basically meaning my entire C and F drive(only 2 HD's I have) are completely exposed to anyone in my LAN. Or can I open these because it's my own machine?

• Can remote LogMeIn Hamachi users access our local LAN?

  - by Kev

  Unknown to me, one of the kids has installed LogMeIn Hamachi on his PC so that he can access and play on his pal's Minecraft server, and vice versa. One of the things I did was disable the Client for Microsoft Networks and File and Printer Sharing for Microsoft Networks on the Hamachi NIC in Windows 7's Network Connections. However, my lack of fu when it comes to these types of services is leaving me feeling a little uncomfortable about him using this. Is there anything I should be worried about here? For example, can his friends access our local LAN (which has a number of NAS boxes with unsecured shares) and get up to no good?
