• In Opera 11, how can I set up shortcuts to switch to specific tabs?

  - by gphilip

  In Firefox on Linux, we can use Alt+1, Alt+2, etc. to switch to the first, second, etc. tabs, till the 9th tab. This is very useful to switch between tabs. In Opera 11 on Linux, I couldn't find a way to do this: the only way to switch among tabs seems to be to use Ctrl+Tab and then cycle till we reach the tab that we want. Needless to say, this "linear access" method is slower (and more annoying) than the random access available in FF. So my question is: How can I set up shortcuts in Opera 11 on Linux so that I can switch to one of the first nine tabs using a numbered shortcut?

• Snow Leopard, PHP, and MySQL

  - by Peter

  I have just installed Snow Leopard and now my PHP/MySQL program ends in a "Segmentation fault". I have been searching the web for a solution, I realize that there are some issues with SL/PHP/MySQL, but I have not found anything that works yet. I downloaded the binary MySQL package mysql-5.1.42-osx10.6-x86_64. I have updated the php.ini file as suggested at various posts. When I run PHP and connect to the MySQL server the behavior is a bit random. In many cases it works fine to connect and read data. In my specific case the PHP program constructs a LOAD DATA LOCAL INFILE ... statement to load data from a text file. It should do several such queries after each other in a loop. It works one time but the halts in a "Segmentation fault". The program worked fine in Leopard, but not now. My versions are: OS 10.6.2, PHP 5.3.0, MySQL 5.1.42

• Multiple .bkf files created in Backupexec 12.5 or 2010 related to heavy I/O?

  - by syuusuke

  Hey everyone, I was wondering if anyone who has used backupexec 12.5 or 2010 have ever experienced multiple .bkf files created for a single job. To describe what I mean by multiple files, the .bkf are being created with random file sizes under 2GB even though I've assigned the setting to chop the file after 10GB size. Some jobs will create 20x .bkf files in 1 job with file chunks ranging from 50MB to 800MB sizes. Is this is a sign of heavy I/O issues? Bandwidth limitations? I'm not sure, I'm here to seek some advices and suggestions. I've setup another backup server with the same exact settings and they seem to create a new .bkf file when 10GB limit has been reached. Although I am backing up different machines but I know my settings are an exact match to the problematic or atleast I think it's a problem.

• spurious hardware memory 'errors' on hp dl380 g5's being generated

  - by friedchicken

  Hi All, i've got 2 new HP dl380g5 servers running HP's esxi4 patched to 219382. they have both been patched up to the latest hp firmware levels (firmware cd 8.7) both are running 32gb (4 x 8gb sticks) both servers are showing the same symptoms - the memory lights come on for two (random) dimms on the front of the server and the health led turns red. sometimes the server stays up and running with no problems. othertimes the server locks dead and only a power reset can bring it back. there is nothing showing in the ilo logs and nothing within the vmware hardware monitoring. the memory has been replaced i've got other customers that have been running dl380g5's with out any issues on esx3.5 - this is our first vsphere deployment with them. these are meant to go live soon so any advice would be great. thanks in advance.

• File corruption

  - by firesoul

  Recently, almost every file I try to copy into my HDDs gets corrupted. When writing to the disk, some portion of the file is replaced by random bytes (Checked using Diff apps) There's no problem reading existing files. I'm pretty sure it's not the HDD, becasue I've tried another HDD (a brand new 1TB WD) and the problem still remains. I have an AMD Athlon 64 X2 CPU, an ASUS M2NE motherboard, 2 WD SATA II HDDs (320GB + 1TB) and 3GB of Corsair RAM. My OS is Windows 7 (64 bit) Now, what could be the cause of this? If it's the motherboard, can it be fixed by using a PCI SATA card?

• Is there a simple way to make my laptop always turn on muted? [closed]

  - by tehp

  Possible Duplicate: How to mute the sound output on Windows Start up? I carry a laptop around. Sometimes I'll open it up in meetings or other quiet settings. The speaker is interrupted by the windows startup noise or Pandora refreshing it's page and starting to play a song or some other random computer noise. Is there a simple way to mute the sound on startup/resume/whatever? Kind of like the BIOS option to turn on or off the Num Lock.

• Rendering artifact when using Eclipse (FlashBuilder)

  - by Demian Brecht

  Once in a while when using FlashBuilder, I'll get a rendering artifact that doesn't go away until I do a full reboot. This artifact seems to be caused by a popup triggered by code documentation popups (hovering over keywords) that linger after the popup has been dismissed: This behavior is seemingly random and incredibly annoying. It only happens when using Eclipse (although I don't run many Java-based programs) and run an NVidia Quadro 2000M (with the latest drivers - figured I'd try that before posting). Has anyone else encountered this issue? Any known solutions?

• How to handle knowledge handover effectively?

  - by Zizzencs

  Let's say a large enterprise opens a new office in (insert random location here) and want the new colleges up to speed as fast as possible. Let's also say this enterprise is a very typical one with a complex environment, lots of history and almost full lack of documentation. What's already been decided is that the new colleges will receive howto-style documentation for the most typical tasks and will get seme architecture documentation for some of the more complicated systems. Any ideas about improving this process? And more specifically, how should such a howto document look like to be helpful?

• Using openssl command line tool to encrypt/decrypt data, DES ECB

  - by smsrecv

  Hello How can I create a random 64 bit key for DEC ECB encryption/decryption, and then use the same key for encryption/decryption many times? All this must be done using openssl command line tool. In all the examples I have seen, they do not use a "key", they use "password". But I need a key - array of bytes - because I need to send it to the other party (I don't know which API they use for cryptography.) Then I need to use this key - array of bytes - to encrypt/decrypt data. Thnak you

• Screenflick Audio option in MacBook Pro

  - by John

  When after I shut down my MacBook Pro by holding the power button for a few sec, (which I found is bad for the computer, so I will not do anymore) I found that my speaker doesn't play until I plug in and out earphone into the machine. When my speaker is not working like this, and when I am on a random webcam chatting site like chatroulette.com, they can hear the music playing on my iTunes when I choose Screenflick Audio option in the Mic setting. But when the Speaker is working back again, they don't hear the music playing even when I do Screenflick Audio mode. How can I make it work? Also, how do you make the chatting partner hear my music playing on my computer while I talk to them (not via my speaker, since it's bad quality).

• Messages going missing from Apple mailboxes

  - by Ho Li Cow

  A colleague has noticed random messages being deleted from her Apple Mailboxes. e.g. Message sent to client - client replies - original message nowhere to be found. Not in sent items/sent messages/junk/trash. No rules set up. Have tried rebuilding mailboxes but message doesn't show up. Quite worrying really as it was only noticed by chance so don't know how long/how widespread it is. Mail is controlled by Exchange 2003 server. Anyone come across this before or know what's happening? Many thanks MBP 2.53GHz OS X 10.5.8 Mail 3.6

• Any examples of a complex, changeable system modelled with a spreadsheet?

  - by andygrunt

  When I asked this question using games as the example (hoping it would be more likely to have been done), it was closed as being off topic so let me ask it this way... Has anyone used a spreadsheet to model a complex, changeable system (something like crowd behaviour, weather systems, a closed ecology, evolution or whatever) and if so, can you point me at it? I'm hoping for a normal (albeit complex) spreadsheet using the spready's inbuilt formulae and functions rather than something specially coded. I'm also after something where it's possible to change the variables and see the changed outcome - perhaps the variables change using random numbers or the like.

• Windows Xp, Svchost.exe connecting to different ips with remote port 445

  - by Coll911

  Im using Windows Xp professional Sp2 Whenever i start my windows, svchost.exe starts connecting to all the possible ips on lan like from 192.168.1.2 to 192.168.1.200 The local port ranges from 1000-1099 and the remote port being 445. After its done with the local ips, it starts connecting to other random ips. I tried blocking connections to the port 445 using the local security polices but it didn't work Is there any possible way i could prevent svchost from connecting to these ips without involving any firewall installed ? since my pc slows down due to the load I'd be thankful for any advices

• Rsync fails for files that start with underscore when destination is zfs

  - by Eric

  everyone. I'm using rsync3.1.0pre1 on Mac OS X 10.8.5, and am trying to rsync one folder to another. The destination is a ZFS volume mounted via SMB. The problem I'm having is that files that start with underscore (e.g., '_filename.jpg') are not being successfully synced to the destination. I get the following error message: rsync: mkstemp "/path/to/destination/._filename.jpg.NUgYJw" failed: Permission denied (13) In this case, '_filename.jpg' does not make it to the destination. I understand that rsync creates hidden, temporary files at the destination which are preceded with '.' and have a random file extension appended on the end. But the original filename starts with '', not '.', and I haven't asked rsync to copy extended attributes / resource forks over (unless it always does it). The rsync command I'm using is: rsync -avE --exclude='.DS_Store' --exclude '.Trash' --exclude 'Thumbs.db' --exclude '._*' --delete /source/ /destination/ Has anyone found a way around this problem? Thank you!

• root domain to www forwarding issue

  - by user182332

  I want to forward my root domain(yourdomain.com) to www.yourdomain.com Should I delete the A record of the root domain and then setup 301 permanent forwarding to www.yourdomain.com? I am hosting my app on heroku. So I don't really have an IP address to setup an A record. The thing is I first deleted the A record of my root domain and then forwarded it. I pinged it and here is the result - ping yourdomain.com ping: cannot resolve yourdomain.com: Unknown host Update and some more information - I am hosting a static website. And managing the DNS on cloudflare.com I added an A record for yourdomain.com - 184.168.221.51 Just an random IP.

• wireless dropping out

  - by Sam

  My wireless network connection is dropping out and its driving me nuts. It is weird because it happens at totally random intervals and other devices work while my computer has been dropped. Both my USB dongle and wifi card randomly disconnect from the router and I am unable to connect for a couple of minutes. It is especially irritating because two different adapters are failing at the same time, sounds like a software problem to me, but where? Both my laptop and iPod remain connected when the connection drops. What on earth is happening? I doubt its the router because the other devices would disconnect as well.

• How do I know when my on-board ethernet is dead? (Realtek 8112L LAN controller w/ AI NET2 )

  - by Usagi

  So I have an ASUS P7P55D-E Pro motherboard. It has an on-board Realtek 8112L LAN controller w/ AI NET2. I suspect that my LAN controller is dead but I don't really know for sure. This is what I know thus far: Everything was working, I have a triple booted system and ethernet was functional under Linux, Win7, and OSX. My ethernet is no longer functional under all three of the operating systems. I was experiencing random momentary internet outages before everything finally went dark. I don't know much about the AI NET BIOS tool but I believe it just checks for ethernet problems before you boot into an operating system. In any case, it doesn't find a connection upon boot. I've checked the connection on a couple of other machines and everything worked fine. I think I already know the answer to my question, but are there any other possible explanations, or is it dead?

• Forums that compell one to read? [closed]

  - by Alex

  I want to create a forum for a very specific, somewhat fight-club-like area of information. The participants need to be unique, not people I know. To be precise, it needs to be an entirely random set of participants. To do this I am going on the assumption that whatever a potential viewer sees when he visits this particular domain he will be COMPELLED to go further. He feels an intense urge within him to read more. I need forum software that will evoke this feeling regardless of the content. Minimal and aesthetically fluid and functional. It must have.. zen.. What are my options?

• Munin "Available entropy" when using adress space layout randomization

  - by clawspoon

  Having just configured munin for statistics logging on my gentoo server (hardened profile), I am noticing that my "Available entropy" is consitently in the 200-300 range. This seems way to low, so I checked it manually using the command $ cat /proc/sys/kernel/random/entropy_avail 3544 Odd. Consistently very low values in Munin and practically filled up when checking manually. After thinking about the problem for a while I came to the conclusion that the problem is probably that I'm using Adress Space Layout Randomization which is using the entropy when running commands/programs. Since Munin runs a whole slew of programs all the entropy is used up, and Munin then measures how much entropy there is, resulting in the low values. Does anyone have any experience with this? How can this be avoided?

• Odd SVN Checkout failures occur frequenctly on VMWare virtual machines

  - by snowballhg

  We've recently been experiencing seemingly random SVN checkout failures on our Hudson build system. Google search has failed me; I'm hoping the super user community can help me out :-) We are occasionally receiving the following SVN error when our Hudson build jobs checkout source via the Hudson Subversion plug-in (which uses svn kit): ERROR: Failed to check out http://server/svnroot/trunk org.tmatesoft.svn.core.SVNException: svn: Processing REPORT request response failed: XML document structures must start and end within the same entity. (/svnroot/!svn/vcc/default) svn: REPORT request failed on '/svnroot/!svn/vcc/default' This issue seems to only occur when checking out from our Virtual Machines (Windows XP, Fedora 9, Fedora 12) using Hudson's SVN Plug-in. Systems that use the traditional SVN client seem to work. SVN Server version: 1.6.6 Hudson version: 1.377 Hudson SVN Plugin Version: 1.17 Has anyone dealt with this issue, or have any suggestions? Thanks

• How to check if cell contains a value of another cell

  - by Antonio Oliveira

  Here is the scenario: On column A each cell has random text within it (names, address, account numbers, etc). Column A extends down to over 40 thousand rows. On column B I have a list of (account) numbers. Column B extends down to about 5 thousand rows. I need to filter column A to show only the rows that contain the account numbers that are part of column B. Neither column A nor B are in any specific order. I think he above scenario speaks for itself, but I can provide a quick example if needed (don't want to over complicate it).

• General purpose ticketing/tech support system [closed]

  - by crazybyte

  Possible Duplicate: What’s your favorite ticketing system? I was wondering if somebody could recommend me a very user friendly or simple general purpose ticketing/tech support system. I need something that is web based, preferably open-sourced/free software implemented using PHP, Ruby, Ruby on Rails or Java (as back end) with MySQL or PostgreSQL as database engine. I need something that is not development management oriented or project management oriented like Eventum or similar (random example), something to which the user can connect open a tech support request and be able to follow it until is solved or dropped.I need it to be open-sourced to be able to modify it if there is a need or extend it. I tried a number of such systems available and I found that osTicket or eTicket is something that it's close to what I need, but the code is somewhat flaky and some of the features are working badly or behaving strangely. Any thoughts/advice where to find something similar? Thanks!

  I am trying to use the command line utility Siege to load test a service. The service recieves json in the request body via a POST. I have a file called example-data.json with the json inside. I will eventually turn this into a tiny service which creates random json for testing, but this should do for now I have another file called hit-qa.siege with http://www.qa-url.com POST < example-data.json and i try and run siege -c10 -d1 -r1 -f ops/perf/hammer-dev.siege When I check the logs of the service, it is not recieving anything in the request body. My googles have been fruitless, does anyone know how to accomplish this?
