  • Is Oracle Smartscan really effective?

    - by Vimvq1987
    Oracle is marketing Exadata to our company, and they're focusing on Smartscan, which is, advertised 10x more effective than traditional solution. I don't really understand (and somewhat don't really believe) this solution, because they assume that data is put on separated storage, and no indexes are used, so "1TB data was scanned and only 2MB is returned". So, I want to ask you: is Smartscan really effective. Is it true solution that greatly improves performance or just a buzzword? Thank you so much for your experience

  • Where does ubuntu store keyboard shortcut settings?

    - by Herms
    I'm having trouble setting a keyboard shortcut in Ubuntu. Trying to use the win (super) key as a modifier, but as soon as I press the win key the keyboard shortcut UI just assumes I wanted to use just that key. I figure the easiest thing would be to modify the settings file itself, where I should be able to put in whatever I want. But I can't figure out where that's stored. Does anyone know?

  • How to strip logfile with grep to remove various dispensable information?

    - by NES
    My logfile has the following format: Dec 26 13:11:48 192.168.1.1 kernel: ACCEPT IN=br0 OUT=vlan1 SRC=192.168.1.2 DST=74.125.43.147 LEN=44 TOS=0x00 PREC=0x00 TTL=63 ID=9312 DF PROTO=TCP SPT=11733 DPT=80 WINDOW=5840 RES=0x00 SYN URGP=0 OPT (020405B4) Now i'm trying to remove some dispensable information to make the output better readable and well arranged and put it into a new file. The result should look like this and should only have the following information: Dec 26 13:11:48 192.168.1.2 74.125.43.147 TCP SPT=11733 DPT=80 How to do it?

  • Group your tabs feature Firefox: Automatically sort by domain?

    - by Dan
    I'm using Firefox 8.0 and am enjoying the Group your tabs feature: But I'm not always good at keeping it organized. I'm trying to find a way to automatically put certain domains in certain groups. Probably through a plug-in? All the tab related plug-ins just help cluster your tabs together and don't actually work with the "Group your tabs" feature (which is why I posted the picture, to avoid ambiguity, since grouping tabs can refer to a lot of things).

  • Run WMIC command across network

    - by C-dizzle
    Instead of typing this in a command prompt one at a time: wmic /node:ipaddress /user:administrator /password:mypassword bios get serialnumber How can I run that against one entire subnet and output to a text document? Since I do this every couple months to verify our inventory of computers, I would assume there would be a much of easier way I could put this in a batch script instead of doing it manually.

  • iPhone: how to test that a 3Gs is what it says it is?

    - by Mike
    I'm about to buy a second hand iPhone. It's supposedly a 3Gs; hardly used and de-blocked. Is there any way of checking this through the handset before I give over my money? I recently sold my Nokia W72 and the guy I sold it too put in a code and it showed him my usage details? Any advice given is greatly appreciated. Thanks Mike.

  • Sun Grid Engine : jobs are not well balanced

    - by GlinesMome
    I use Open Grid Scheduler (a fork/copy of Sun Grid Engine). I have tried this configuration from master: # qconf -mattr exechost complex_values slots=8 slave2 # qconf -mq all.q | grep slots slots 100,[slave1=1],[slave2=8] slave1 is down, then I run 10 qsub with a sleep example (so no CPU consumption) but only 4 jobs are run at the same time on slave2 instead of I have put 8 slots. What does I missed ? PS: my goal is to provide infinite slots to force SGE to schedule only via consummable ressources.

  • Always route a keypress to an application regardless of focus

    - by George Mauer
    I have to transcribe some audio (not enough to download dedicated software but enough to put my hacker hat on) and flipping back and forth between vlc and my text editor every time I want to pause is really annoying. Is there a way to always route a key-press (for example F10) to vlc regardless of what window has focus. Bonus - I have a Makey Makey so if I can get this working I can create a pedal and it will be my first real use of it!

  • How can I use a keyfile on a removable USB drive for my encrypted root in Debian?

    - by naivem
    Recently set up root encryption with a couple of LVM volumes inside one LUKS volume, and I am just a little confused as to how I would go about getting it to automatically unlock using a keyfile stored on a USB flash drive, I presume I would have to put the drive in the fstab inside my initramfs (if there is one), and add a hook for USB device support. But I digress, essentially, I want to know what I have to do to enable my LUKS volume (containing all of my partitions sans /boot) to unlock using a keyfile stored on a USB flash drive, rather than a manually entered passphrase.

    I was able to install and run nginx, and passenger but i'm not able to have nginx come up whenever i reboot my server. To start the nginx process i just type in sudo /opt/nginx/sbin/nginx.

    For the past two days, whenever I plug in my USB mouse (which has been working for a long time, previously) into the laptop, my computer restarts! I tried changing mice, but the same thing happens. I have 3 ports, usually, I try one port and the laser does not come on, then I try another one and the laser comes and and off, then I again take out and put it in any port and the damn thing just turns off the computer.

  • Asus K55A Windows 8.1 touchpad smart gestures not working

    - by user291792
    Took me a bit to realize that since upgrading to 8.1 my touchpad smart gestures (two finger scroll, top down swipe, left in swipe, ect) don't work. I have read up a little online but can't seem to find an answer or fix that 1) sounds trustworthy and 2) is put into language and steps that I understand. I already have a hard time navigating windows 8 in general, so any help is awesome, but please dumb it down for me if you can. Thanks -K-

    I have a flash drive that was used primarily on a Mac, and it was ejected improperly. Now when I put it back in, the computer (I tried 2 different Macs,and 3 PCs) does not even register the flash drive- it does not show up in Finder or in My Computer. Any ideas how to get the lost files back?

  • Installing a wiki on Snow Leopard

    - by JPCF
    Hi... I want to install twiki on my mac and serve it from ~/Sites/. Because the wiki has code to be run, I have to modify the user and group of wiki's files and directories, but I'm not sure about the following: 1) It is secure to change the user and group of the directory to the web server's group? If not, what can I do having into account that I'll not put 777 permissions on those files? 2) How are named apache and web user groups? Thanks

  • iTunes and Hulu Playback Choppy and Slow?

    - by Bart Silverstrim
    Specs: Windows XP, latest updates 1.7 ghz Pentium 4 1 gig ram DirectX 9.0c NVIDIA GeForce FX 5200 with 256 meg RAM OpenGL 2.1 The story: Okay, I had an older system laying around that I figured I would try turning into a mini-media system to connect to our TV. I put together a lot of older parts, got it into working order, etc. and hooked it up and voila'...slower, but usable system that displayed to the TV. It could run some things decently. I put in iTunes, it played video okay. Not great, but okay. Played Hulu and since we have a 1Mb download rate, the minimum for their site, there were some choppy moments when watching their shows, but I found that (sadly) changing resolution to 800x600 seemed to help with the issue when running full screen. I downloaded the application called Boxee and installed it. It wouldn't run; apparently the video card in the system supported OpenGL 1.2, and needed at least 1.4. I bought a cheap card, the 5200, with four times the memory in it and support for OpenGL 2.1. Installed, everything seemed fine. iTunes seemed to run fine, the video driver (PNY video card) came with OpenGL 2.1, and Boxee finally ran. I then upgraded to the latest drivers for the video card and ran the DirectX updater from MS. After that, the OpenGL Extension Viewer wouldn't run. It just stayed as an icon in the task bar. Also, any and all videos in iTunes stuttered and went out of sync horribly. Unwatchable. I tried watching Hulu video in Boxee, and it displayed video like it was a series of stills in a very bad powerpoint. Playing straightforward audio-only came through fine, no stutters no hiccups. I tried system restore to roll back updates to pre-directX updates (I thought that seemed to be the time that triggered the weird behavior), no joy. I tried uninstalling and reinstalling the video drivers. I installed updated audio drivers (ensoniq audiopci), nothing helped. I finally wiped the drive last night and tried reinstalling everything and restoring my iTunes content via an import from a backup. Fresh install, no updater on the video card or directx. the problem was still there although I haven't tested Hulu, the iTunes player is still stuttering like crazy if I play video, fine if I play audio. I know the processor isn't high in heft, but with one gig of RAM and the fact that it seemed to do okay before I thought that the problem must be software related. Has anyone else run into this sort of issue and have a solution other than "buy a new computer"? What specs seem to work with video at the low end for you? Right now the system is of little use other than keeping my music library and iTunes apps synced with my iPod.
