  • mysql 5.0.23 vs 5.5 performance benefits and upgrade issues ?

    - by WarDoGG
    I have been told that mysql 5.5 has a significant performanance boost compared to 5.0 Our server handles alot of data (around 30 million records processed per 5-10 seconds) and requires every drop of performance boost we can give. Will it be beneficial if we upgrade from 5.0.23 to mysql 5.5 ? Also, we have lots of database indexes setup on the tables and i've been told that sometimes the indexes become corrupt after a version upgrade and they have to be rebuilt. Is this true ?

  • Saving large webpage as Image

    - by Nalaka526
    I'm trying to save webpage as an image. The web page I'm trying to save is bit long and has many images (http://www.boston.com/bigpicture/2012/10/hurricane_sandy_the_superstorm.html) I tried Google Chrome Screen Capture Extention and few other Chrome Screen Capture Plugins but all gave empty image as output. How to overcome this? Is there any other known Plugin (non Chrome is OK) to save large web page as an Image?

  • What are the steps to set up a Hyper-V solution with one NIC

    - by Cameron Aziz
    I have successfully installed centos on a virtual machine via Hyper-V on Windows Server 2008 R2. This server has one NIC. I have created a virtual NIC, and virtual subnet, and within the virtual machine (via console) I can ping the gateway. But not google. Is there certain steps I am missing, I feel like I'm one setting away. Im not sure what other information would be useful. Here is the ipconfig of the host: Ethernet adapter vNIC losangeles1_1: Connection-specific DNS Suffix .. : IPv4 Address. . . . . . . . . . . : 10.10.0.1 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : Ethernet adapter Local Area Connection 2: Connection-specific DNS Suffix .. : IPv4 Address. . . . . . . . . . . : 72.51.43.43 Subnet Mask . . . . . . . . . . . : 255.255.255.192 Default Gateway . . . . . . . . . : 72.51.43.1

  • What to do with old OS install media?

    - by dwj
    I'm doing an end-of-the-year clean up and found some old OS install media - Mac OS X 10.3.5, Windows 2000, Windows XP. It seems wrong to just throw them out but they can't have a home with me anymore.  Is there some place I can donate them to?  Anyone know of anyone collecting this stuff for posterity?

  • OS X Snow Leopard 10.6 Refuses to Load Websites the first time intermittently

    - by Brandon
    Many times when I am browsing the web, Snow Leopard will sit and load a site for 20 seconds or more, until it times out and says it cannot be displayed. If I refresh, it loads RIGHT away, every time. The issue is intermittent but happens from once every couple of days to a few times a day. So the long and short of it is this: Aluminum MacBook (Non-Pro) 2.4GHz Core2Duo, 4GB DDR3 I am using 10.6.6 but I have had this issue since 10.6.0 It happens in Firefox, Chrome, and Safari I have flushed my DNS (using the command 'blablabla flush') I am using custom DNS servers which I hoped would fix it but it had no effect* I am running Apache currently but haven't been for most of the time I've reformatted multiple times, always experiencing the issue I am on Cox cable internet, with a Motorola Surfboard & a Belkin F6D4230-4 v1 (Pre?) N wireless router. I've put the router in G only & N only & G+N to no effect It seems to be domain dependant as I can sometimes load the Google cache right away, and sometimes other sites will load but Google will refuse My Powerbook G4 with Leopard, other Windows XP laptops, & my wired Win7 desktop do not suffer from the issue. *I recently started using these to escape the awful Cox redirect page on timeouts I'm almost positive the issue has happened on other networks but I can't recall a specific instance (I have a terrible memory). The problem is intermittent and fixable enough (I just have to wait until it times out and hit refresh one time) but incredibly annoying since I'm constantly reading documentation from a large variety of sites. EDIT: To clarify, this happens with ALL sites, not only specific sites. I haven't been able to detect any pattern to the failures, but one day Google.com will refuse to load while reddit.com will, and the next day vice versa. Keep in mind that waiting for a timeout and hitting refresh loads the page right away, every time. If I don't wait for the timeout, opening more links, hitting refresh, and clicking the link a billion times have no effect. It seems to be domain neutral, affecting sites seemingly at random. It doesn't seem to have anything to do with connection inactivity either, because I will be SSHed into different servers, uploading files, browsing, downloading, etc, and it will just quit loading Jquery.com (for example) until I sit and wait for a timeout. /EDIT This is my last resort. Please, someone, tell me what is happening. Thank you.

  • Quicksilver doesn't open PDF's like it used to

    - by Niels Bom
    I've been using Quicksilver for a while now but lately I've been getting this problem that QS doesn't show the Acrobat Reader icon when a PDF is selected, but goes to the "Open With" tab. See the screenshot here: http://skitch.com/niels.bom/n8nw5/google-reader-1000 Is this a bug? Or did I somehow bork a preference setting? I'm using QS B54, 3815, which is the latest AFAIK and Mac OS X 10.5.8. Thanks!

  • Why is my router not routing?

    - by dwj
    Starting a week and half ago my router stopped working with my cable modem. I went to sleep with it working and woke up with it not. I swapped in another router and am still having issues; I was gone for 10 days so now I'm back to trying to figure it out. While I was gone I left everything (cable modem, router, and computer) powered off. My setup: Comcast Ambit cable modem (from Comcast) Netgear WGR614 v4 router -- replaced with Linksys WRT54GS v1.1 Windows XP SP3 other computers, all currently unplugged The modem is using the firmware (ver 2.105.2001) provided by Comcast; hardware version 1.3 The Linksys router is using FW ver 4.71.4 (latest for this release of HW), factory defaults I am only using the wired connections; no wireless. I have swapped out all of the cat5 cable. If I plug my computer directly into the cable modem, I can ping by name or number. Everything works perfectly. If I plug my computer into the router and the router into the modem, I cannot access anything outside of my local network. This is the exact setup I've used for the past 5 years; there were no changes in the past year. Now here's the interesting part: I can log into the Linksys router and get status information from it; everything appears good. Using the Diagnostics, I can run ping and traceroute to any site on the internet. These work perfectly. From my computer, I can ping the router and the modem. However, I cannot ping anything on the internet by with name or number. If I plug in another computer, I can ping it successfully. I've included two transcripts below that show these two attempts. Addresses, DNS, gateways, etc. look good. I cannot access the internet through either router. I am at a loss here. Suggestions? Help!

  • How to stop a ICMP attack?

    - by cumhur onat
    We are under a heavy icmp flood attack. Tcpdump shows the result below. Altough we have blocked ICMP with iptables tcpdump still prints icmp packets. I've also attached iptables configuration and "top" result. Is there any thing I can do to completely stop icmp packets?

  • Does RVM "failover" to another ruby instance on error?

    - by JohnMetta
    Have a strange problem in that I have a Rake task that seems to be using multiple versions of Ruby. When one fails, it seems to try another one. Details MacBook running 10.6.5 rvm 1.1.0 Rubies: 1.8.7-p302, ree-1.8.7-2010.02, ruby-1.9.2-p0 Rake 0.8.7 Gem 1.3.7 Veewee (provisioning Virtual Machines using Opcode.com, Vagrant and Chef) I'm not entirely sure the specific details of the error matter, but since it might be an issue with Veewee itself. So, what I'm trying to do is build a new box base on a veewee definition. The command fails with an error about a missing method- but what's interesting is how it fails. Errors I managed to figure out that if I only have one Ruby installed with RVM, it just fails. If I have more than one Ruby install, it fails at the same place, but execution seems to continue in another interpreter. Here are two different clipped console outputs. I've clipped them for size. The full outputs of each error are available as a gist. One Ruby version installed Here is the command run when I only have a single version of Ruby (1.8.7) available in RVM boudica:veewee john$ rvm rake build['mettabox'] --trace rvm 1.1.0 by Wayne E.

Prior to doing this, I used "rvm use 1.8.7." Again, I don't know how important the details of the specific errors are- what's interesting to me is that there are three separate errors- each with it's own stacktrace- and each in a different Ruby interpreter. Look at the bottom of each stacktrace and you'll see that they are all sourced from different interpreter locations- First ree-1.8.7, then ruby-1.8.7, then ruby-1.9.2: boudica:veewee john$ rvm rake build['mettabox'] --trace rvm 1.1.0 by Wayne E.

Discussion Does anyone have any idea what's going on here? Has anyone seen this "failover"-like behavior before? It seems strange to me that the first exception would not halt execution as it did with one interpreter, but I wonder if there are things happening when RVM is installed that we Ruby developers are not considering.

    - by iamrohitbanga
    I have a Netgear WG311 v2 wireless card. It was working fine on vista. Now I have installed Windows 7 and the device is not identified. Device Manager shows it as an Ethernet card. When I update the driver using the list provided with the Windows distribution. It shows it under Wireless devices in Device Manager but it says device cannot start code 10. Any idea on how to install it.

  • How to boot linux direct to application on console with no login

    - by amanda
    I have a need to start an application on bootup on the linux console and I do not have a need for any type of login or security. I do not need any ALT-F1,F2,etc virtual consoles but I would like to allow SSH access via the network port for debugging, loading, etc. The application is a SDL graphics program running with fbcon as the SDL_VIDEODRIVER if that matters. I'm currently using Fedora 10 and 12 but any distro that supports SDL using the fbcon framebuffer would be acceptable.

  • Linux buffer cache effect on IO writes?

    - by Patrick LeBoutillier
    I'm copying large files (3 x 30G) between 2 filesystems on a Linux server (kernel 2.6.37, 16 cores, 32G RAM) and I'm getting poor performance. I suspect that the usage of the buffer cache is killing the I/O performance. To try and narrow down the problem I used fio directly on the SAS disk to monitor the performance. Here is the output of 2 fio runs (the first with direct=1, the second one direct=0): Config: [test] rw=write blocksize=32k size=20G filename=/dev/sda # direct=1 Run 1: test: (g=0): rw=write, bs=32K-32K/32K-32K, ioengine=sync, iodepth=1 Starting 1 process Jobs: 1 (f=1): [W] [100.0% done] [0K/205M /s] [0/6K iops] [eta 00m:00s] test: (groupid=0, jobs=1): err= 0: pid=4667 write: io=20,480MB, bw=199MB/s, iops=6,381, runt=102698msec clat (usec): min=104, max=13,388, avg=152.06, stdev=72.43 bw (KB/s) : min=192448, max=213824, per=100.01%, avg=204232.82, stdev=4084.67 cpu : usr=3.37%, sys=16.55%, ctx=655410, majf=0, minf=29 IO depths : 1=100.0%, 2=0.0%, 4=0.0%, 8=0.0%, 16=0.0%, 32=0.0%, >=64=0.0% submit : 0=0.0%, 4=100.0%, 8=0.0%, 16=0.0%, 32=0.0%, 64=0.0%, >=64=0.0% complete : 0=0.0%, 4=100.0%, 8=0.0%, 16=0.0%, 32=0.0%, 64=0.0%, >=64=0.0% issued r/w: total=0/655360, short=0/0 lat (usec): 250=99.50%, 500=0.45%, 750=0.01%, 1000=0.01% lat (msec): 2=0.01%, 4=0.02%, 10=0.01%, 20=0.01% Run status group 0 (all jobs): WRITE: io=20,480MB, aggrb=199MB/s, minb=204MB/s, maxb=204MB/s, mint=102698msec, maxt=102698msec Disk stats (read/write): sda: ios=0/655238, merge=0/0, ticks=0/79552, in_queue=78640, util=76.55% Run 2: test: (g=0): rw=write, bs=32K-32K/32K-32K, ioengine=sync, iodepth=1 Starting 1 process Jobs: 1 (f=1): [W] [100.0% done] [0K/0K /s] [0/0 iops] [eta 00m:00s] test: (groupid=0, jobs=1): err= 0: pid=4733 write: io=20,480MB, bw=91,265KB/s, iops=2,852, runt=229786msec clat (usec): min=16, max=127K, avg=349.53, stdev=4694.98 bw (KB/s) : min=56013, max=1390016, per=101.47%, avg=92607.31, stdev=167453.17 cpu : usr=0.41%, sys=6.93%, ctx=21128, majf=0, minf=33 IO depths : 1=100.0%, 2=0.0%, 4=0.0%, 8=0.0%, 16=0.0%, 32=0.0%, >=64=0.0% submit : 0=0.0%, 4=100.0%, 8=0.0%, 16=0.0%, 32=0.0%, 64=0.0%, >=64=0.0% complete : 0=0.0%, 4=100.0%, 8=0.0%, 16=0.0%, 32=0.0%, 64=0.0%, >=64=0.0% issued r/w: total=0/655360, short=0/0 lat (usec): 20=5.53%, 50=93.89%, 100=0.02%, 250=0.01%, 500=0.01% lat (msec): 2=0.01%, 4=0.01%, 10=0.01%, 20=0.01%, 50=0.12% lat (msec): 100=0.38%, 250=0.04% Run status group 0 (all jobs): WRITE: io=20,480MB, aggrb=91,265KB/s, minb=93,455KB/s, maxb=93,455KB/s, mint=229786msec, maxt=229786msec Disk stats (read/write): sda: ios=8/79811, merge=7/7721388, ticks=9/32418456, in_queue=32471983, util=98.98% I'm not knowledgeable enough with fio to interpret the results, but I don't expect the overall performance using the buffer cache to be 50% less than with O_DIRECT. Can someone help me interpret the fio output? Are there any kernel tunings that could fix/minimize the problem? Thanks a lot,

    I have a question regarding Layer Markers in AE. What I'm trying to do is have a layer start off normal then in the time line I'll place a marker and have it change its color using Effect Color correction Change color to. The hue will change from 0% to 50% for 10 frames then turn back to normal. How would I go about doing this?

  • wondering how much data bandwidth can a 3G gsm cell tower can support?

    - by Karim
    i was always wondering how many simaltinues users can a 3G tower supports with its data rates? i mean they advertize 28.8Mb/Sec for the 3G Data but in reallity if a lot of people use it say 10 , it wont give 288Mb/Sec bandwidth. i didnt find anywhere where such information is published so i thought to ask here. dont know why the cell operators keep it such a secret :)
